Debentures, Old 2007 Debentures, Old 2017 Debentures, Old 7.95% 2027 Debentures, Old 6.95% 2027 Debentures, Old 7.25% 2027 Debentures, and Old 2032 Debentures (collectively, the "Old Debentures"), respectively, except that (i) the New Debentures will be registered under the Securities Act of 1933, as amended (the "Securities Act"), and hence will not bear legends restricting the transfer thereof and (ii) the holders of the New Debentures will not be entitled to certain rights of holders of the Old Debentures under the Registration Rights Agreement (as defined herein), which rights will terminate upon the consummation of the Exchange Offers. The New 2002 Debentures, New 2004 Debentures, New 2007 Debentures, New 2017 Debentures, New 7.95% 2027 Debentures, New 6.95% 2027 Debentures, New 7.25% 2027 Debentures, and New 2032 Debentures will evidence the same debt as the Old 2002 Debentures, Old 2004 Debentures, Old 2007 Debentures, Old 2017 Debentures, Old 7.95% 2027 Debentures, Old 6.95% 2027 Debentures, Old 7.25% 2027 Debentures, and Old 2032 Debentures, respectively, and will be entitled to the benefits of an indenture, dated as of August 1, 1990 and supplemented and amended by a First Supplemental Indenture dated as of June 15, 1991 and a Second Supplemental Indenture dated as of May 6, 1997 (as supplemented and amended, the "Indenture"), governing the Old Debentures and the New Debentures. The Indenture provides for the issuance of both the New Debentures and the Old Debentures. The New 2002 Debentures and the Old 2002 Debentures are sometimes referred to herein collectively as the "2002 Debentures"; the New 2004 Debentures and the Old 2004 Debentures are sometimes referred to herein collectively as the "2004 Debentures"; the New 2007 Debentures and the Old 2007 Debentures are sometimes referred to herein collectively as the "2007 Debentures"; the New 2017 Debentures and the Old 2017 Debentures are sometimes referred to herein collectively as the "2017 Debentures"; the New 7.95% 2027 Debentures and the Old 7.95% 2027 Debentures are sometimes referred to herein collectively as the "7.95% 2027 Debentures"; the New 6.95% 2027 Debentures and the Old 6.95% 2027 Debentures are sometimes referred to herein collectively as the "6.95% 2027 Debentures"; the New 7.25% 2027 Debentures and the Old 7.25% 2027 Debentures are sometimes referred to herein collectively as the "7.25% 2027 Debentures"; the Old 2032 Debentures and the New 2032 Debentures are sometimes referred to herein collectively as the "2032 Debentures"; and the 2002 Debentures, the 2004 Debentures, the 2007 Debentures, the 2017 Debentures, the 7.95% 2027 Debentures, the 6.95% 2027 Debentures, the 7.25% 2027 Debentures, and the 2032 Debentures are sometimes referred to herein collectively as the "Debentures."

Interest on each series of the Debentures will be paid semiannually on May 1 and November 1 of each year, commencing on November 1, 1997. The 2032 Debentures are not redeemable prior to May 1, 2007. On or after that date, the 2032 Debentures will be redeemable at the option of the Company, as a whole or in part, at any time on at least 30 days' notice, at the respective prices indicated herein. None of the other series of Debentures are redeemable at the Company's option prior to maturity. Each holder of the 6.95% 2027 Debentures may require the Company to repurchase all or a portion of such series owned by such holder on May 1, 2002 at a purchase price equal to 100% of the principal amount thereof plus accrued interest thereon. Each holder of the 7.25% 2027 Debentures may require the Company to repurchase all or a portion of such series owned by such holder on May 1, 2005 at a purchase price equal to 100% of the principal amount thereof. None of the series of Debentures is subject to any sinking fund. See "Description of New Debentures."

Prior to the Exchange Offers, there has been no public market for the Old Debentures. The Company does not intend to list the New Debentures on any securities exchange or to seek approval for quotation through any automated quotation system. There can be no assurance that an active market for the New Debentures will develop. To the extent that a market for the New Debentures does develop, the market value of the New Debentures will depend on market conditions (such as yields on alternative investments), general economic conditions, the Company's financial condition and other conditions. Such conditions might cause the New Debentures, to the extent that they are actively traded, to trade at a significant discount from face value.

Except as discussed below, the New Debentures will be available only in book-entry form. The Company expects that the New Debentures issued pursuant to the Exchange Offers will be issued in the form of one or more fully registered global debentures that will be deposited with, or on behalf of, The Depository Trust Company ("DTC") and registered in its name or in the name of Cede & Co., as its nominee. Beneficial interests

i

in the global debentures representing the New Debentures will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its participants. After the initial issuance of such global debentures, New Debentures in certificated form will be issued in exchange for the global debentures only in accordance with the terms and conditions set forth in the Indenture. See "Description of the New Debentures--Book-Entry, Delivery and Form" and "Description of the New Debentures--Certificated Debentures."

The Company will accept for exchange any and all Old Debentures which are properly tendered in the Exchange Offers prior to 5:00 p.m., New York City time, on , 1997 (if and as extended, the "Expiration Date"). Tenders of Old Debentures may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date. The Exchange Offers are not conditioned upon any minimum principal amount of Old Debentures being tendered for exchange. Old Debentures may be tendered only in integral multiples of $1,000. The Company may terminate the Exchange Offers in certain circumstances described herein. See "The Exchange Offers." In the event the Company terminates any or all of the Exchange Offers and does not accept for exchange any of the Old 2002 Debentures, Old 2004 Debentures, Old 2007 Debentures, Old 2017 Debentures, Old 7.95% 2027 Debentures, Old 6.95% 2027 Debentures, Old 7.25% 2027 Debentures, or Old 2032 Debentures, as the case may be, the Company will promptly return all previously tendered Old 2002 Debentures, Old 2004 Debentures, Old 2007 Debentures, Old 2017 Debentures, Old 7.95% 2027 Debentures, Old 6.95% 2027 Debentures, Old 7.25% 2027 Debentures, and Old 2032 Debentures, as the case may be, to the holders thereof.

Based on a previous interpretation by the staff of the Securities and Exchange Commission (the "Commission") set forth in no-action letters to third parties, the Company believes that the New Debentures issued pursuant to the Exchange Offers in exchange for Old Debentures may be offered for resale, resold, and otherwise transferred by a holder thereof (other than (i) a broker-dealer who purchases such New Debentures directly from the Company to resell pursuant to Rule 144A or any other available exemption under the Securities Act or (ii) a person that is an affiliate of the Company (within the meaning of Rule 405 under the Securities Act)) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the holder is acquiring the New Debentures in such holder's ordinary course of business and is not participating, and has no arrangement or understanding with any person to participate, in the distribution of the New Debentures. Holders of Old Debentures wishing to accept any or all of the Exchange Offers must represent to the Company that such conditions have been met.

Each broker-dealer that receives New Debentures for its own account pursuant to any or all of the Exchange Offers must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Debentures. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter," within the meaning of the Securities Act, in connection with the resale of New Debentures received in exchange for Old Debentures where such Old Debentures were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the Expiration Date, it will make this Prospectus available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution."

The Company believes that none of the registered holders of the Old Debentures is an affiliate (as such term is defined in Rule 405 under the Securities Act) of the Company. The Company has not entered into any arrangement or understanding with any person to distribute the New Debentures to be received in the Exchange Offers, and to the best of the Company's information and belief, each person participating in any or all of the Exchange Offers is acquiring the New Debentures in the ordinary course of business and has no arrangement or understanding with any person to participate in the distribution of the New Debentures to be received in any or all of the Exchange Offers.

The Company will not receive any proceeds from the Exchange Offers. The Company has agreed to bear the expenses of the Exchange Offers. No underwriter is being used in connection with the Exchange Offers.

SUMMARY DESCRIPTION OF THE NEW DEBENTURES

The terms of the New Debentures and the Old Debentures are identical in all material respects, except for certain transfer restrictions and registration rights relating to the Old Debentures. Whenever defined terms of the Indenture not otherwise defined herein are referred to, such defined terms are incorporated herein by reference. In the event that (i) by November 2, 1997 (or November 4, 1997 with respect to the Old 2032 Debentures), neither the Registration Statement of which this Prospectus is a part (sometimes referred to herein as the "Exchange Offer Registration Statement") is declared effective nor (if the Exchange Offers are not permitted as described above) the Shelf Registration Statement is filed with the Commission, or (ii) by December 2, 1997 (or December 4, 1997 with respect to the Old 2032 Debentures) , one or more of the Exchange Offers with respect to any series of Debentures is not consummated or the Shelf Registration Statement is not declared effective with respect thereto (each such event referred to in clauses (i) or (ii), a "Registration Default"), interest will accrue on the applicable Old Debentures (in addition to stated interest on such Old Debentures) from and including the next day following each such Registration Default. In each case such additional interest (the "Special Interest") will be payable in cash semiannually in arrears each May 1 and November 1, at a rate per annum equal to 0.25% of the principal amount of such Old Debentures for each such Registration Default. The aggregate amount of Special Interest payable pursuant to the above provisions will in no event exceed 0.25% per annum of the principal amount of such Old Debentures. Upon (a) the effectiveness of the Exchange Offer Registration Statement or the filing of the Shelf Registration Statement after the date set forth in clause (i) above or (b) the consummation of the Exchange Offer for such Old Debentures or the effectiveness of a Shelf Registration Statement, as the case may be, after the date set forth in clause (ii) above, the Special Interest payable on such Old Debentures as a result of the applicable Registration Default will cease to accrue.

The New Debentures will bear interest from the most recent date to which interest has been paid on the Old Debentures or, if no interest has been paid on the Old Debentures, from May 1, 1997. Accordingly, registered

7

holders of New Debentures on the relevant record date for the first interest payment date following the consummation of the Exchange Offers will receive interest accruing from the most recent date to which interest has been paid on the Old Debentures or, if no interest has been paid, from May 1, 1997. Old Debentures accepted for exchange will cease to accrue interest from and after the date of consummation of the Exchange Offers. Holders whose Old Debentures are accepted for exchange will not receive any payment in respect of interest on such Old Debentures otherwise payable on any interest payment date, the record date for which occurs on or after consummation of the Exchange Offers.

RISK FACTORS

Holders of Old Debentures should carefully review the information contained elsewhere in this Prospectus and should particularly consider the following matters.

CONSEQUENCES OF FAILURE TO EXCHANGE OLD DEBENTURES

The Old Debentures have not been registered under the Securities Act or any state securities laws and therefore may not be offered, sold or otherwise transferred except in compliance with the registration requirements of the Securities Act and any other applicable securities laws, or pursuant to an exemption therefrom or in a transaction not subject thereto, and in each case in compliance with certain other conditions and restrictions. Old Debentures which remain outstanding after consummation of the Exchange Offers will continue to bear a legend reflecting such restrictions on transfer. In addition, upon consummation of the Exchange Offers, holders of Old Debentures which remain outstanding will not be entitled to any rights to have such Old Debentures registered under the Securities Act or to any similar rights under the Registration Rights Agreement (subject to certain limited exceptions as described herein). See "Description of the New Debentures--Registration Rights Agreement." The Company does not intend to register under the Securities Act any Old Debentures which remain outstanding after consummation of the Exchange Offers (subject to such limited exceptions, if applicable). To the extent that Old Debentures are tendered and accepted in the Exchange Offers, a holder's ability to sell untendered Old Debentures could be adversely affected. See "The Exchange Offers--Consequences of Failure to Exchange Old Debentures."

ABSENCE OF PUBLIC MARKET

The Old Debentures were issued to, and the Company believes are currently owned by, a relatively small number of beneficial owners. The Old Debentures have not been registered under the Securities Act and will be subject to restrictions on transferability to the extent that they are not exchanged for the New Debentures. Although the New Debentures will generally be permitted to be resold or otherwise transferred by the holders (who are not affiliates of the Company) without compliance with the registration requirements under the Securities Act, they will constitute a new issue of securities with no established trading market. Any market-making activity will be subject to the limits imposed by the Securities Act and the Exchange Act and may be limited during the Exchange Offers. Accordingly, no assurance can be given that an active public or other market will develop for the New Debentures or the Old Debentures or as to the liquidity of or the trading market for the New Debentures or the Old Debentures. If an active public market does not develop, the market price and liquidity of the New Debentures may be adversely affected.

If a public trading market for the New Debentures develops, future trading prices of such securities will depend on many factors, including, among other things, prevailing interest rates, results of operations and the market for similar securities. Depending on prevailing interest rates, the market for similar securities and other factors, including the financial condition of the Company, the New Debentures may trade at a discount.

Notwithstanding the registration of the New Debentures in the Exchange Offers, holders who are "affiliates" (as defined under Rule 405 of the Securities Act) of the Company may publicly offer for sale or resell the New Debentures only in compliance with the provisions of Rule 144 under the Securities Act.

Each broker-dealer that receives New Debentures for its own account in exchange for Old Debentures, where such Old Debentures were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such New Debentures. See "Plan of Distribution."

EXCHANGE OFFER PROCEDURES

Unless tenders are made by book-entry transfer, issuance of the New Debentures in exchange for Old Debentures pursuant to the Exchange Offers will be made only after timely receipt by the Exchange Agent of

10

such Old Debentures, a properly completed and duly executed Letter of Transmittal and all other required documents. Therefore, holders of the Old Debentures desiring to tender such Old Debentures in exchange for New Debentures should allow sufficient time to ensure timely delivery. Neither the Exchange Agent nor the Company is under any duty to give notification of defects or irregularities with respect to the tenders of Old Debentures for exchange.

JOINT CSX/NSC ACQUISITION OF CONRAIL

CSX/NSC Agreement

On April 8, 1997, the Company and Norfolk Southern Corporation, a Virginia corporation ("NSC"), entered into an agreement (the "CSX/NSC Agreement") providing for their joint acquisition of Conrail Inc., a

11

Pennsylvania corporation ("Conrail"), and the division of Conrail's routes and other assets. Conrail is a holding company of which the principal subsidiary is Consolidated Rail Corporation, a Class I freight railroad that operates approximately 10,500 route miles in the Northeast and Midwest of the United States and the Province of Quebec, Canada, and which possesses superior access to certain major northeast markets, including the New York and Boston metropolitan areas. NSC owns an eastern Class I freight railroad, Norfolk Southern Railway Company.

Under the CSX/NSC Agreement, the Company and NSC acquired all outstanding shares of Conrail not already owned by them (the "Shares") for $115 in cash per Share through a jointly owned acquisition entity (the "Acquisition Entity"). Each of the Company and NSC possesses 50% of the voting and management rights of the Acquisition Entity, and non-voting equity is apportioned between the parties to achieve overall economic allocations of 42% for CSX and 58% for NSC (their respective "Percentages"). Following approval by the Surface Transportation Board (the "STB") as described below, Conrail's assets will be segregated within Conrail, and the Company and NSC will each benefit from the operation of a specified portion of the Conrail routes and other assets through the use of various operating arrangements, and certain Conrail assets will be operated for the joint benefit of the Company and NSC.

Acquisition of most of the Conrail Shares was effected under a tender offer, initiated by the Company in December 1996 and amended in April 1997 to include NSC as a co-bidder (the "Joint Tender Offer"), which closed in May 1997. Shortly thereafter, Conrail was merged with a wholly-owned subsidiary of the Acquisition Entity and all remaining Conrail Shares not tendered were converted into the right to receive $115 in cash per share. The aggregate cost of the Joint Tender Offer, the merger and the shares of Conrail already acquired by the Company and NSC was approximately $9.9 billion. Pursuant to the CSX/NSC Agreement, the Company has paid 42%, or approximately $4.2 billion, and NSC has paid 58%, or approximately $5.7 billion, of such cost. These totals include approximately $2.0 billion spent by the Company and $1.0 billion spent by NSC to acquire approximately 30%, in the aggregate, of Conrail's shares prior to the Joint Tender Offer. Including its capitalized transaction costs, the Company's aggregate purchase price was approximately $4.3 billion.

Conrail Shares purchased in the Joint Tender Offer and the merger, together with all Conrail shares previously purchased by the Company and NSC, have been deposited into a voting trust pending STB approval of the joint acquisition, control and division of Conrail by the Company and NSC. Furthermore, by entering into the CSX/NSC Agreement, the Company is obligated under the Pennsylvania anti-takeover laws to purchase any Conrail Shares "put" to the Company in accordance with the procedures of such laws for at least $115 per share in cash.

Joint CSX/NSC STB Application

The exercise of control over Conrail by the Company and NSC remains subject to a number of conditions and approvals, including approval by the STB, which has the authority to modify contract terms and impose additional conditions, including with respect to divestitures, grants of trackage rights and other terms of continuing operations. The Company and NSC intend to file a joint application with the STB in June 1997 for control and division of Conrail and for such other matters as may be required to be approved by the STB. The joint STB application will address traffic flows, operations and related matters; will outline the capital investments each company plans to make in new connections and facilities and to increase capacity on critical routes; and will detail operating savings and other public benefits resulting from the transaction. The application also will contain certain historical and pro forma financial information required by the STB. The STB has issued a scheduling order that provides for issuance of a final STB decision no later than 350 days after the Company and NSC file their joint application. No assurance can be given with respect to the receipt of STB approval or the modifications or conditions that may be imposed in connection therewith.

Proposed Division of Conrail Routes

Until the date the Company and NSC are permitted by the STB to assume control over Conrail (the "Control Date"), Conrail will continue to be managed by its current Board of Directors and management. After

12

the Control Date, Conrail will segregate its assets primarily into two groups to facilitate their separate operation pursuant to leasing, operating, partnership or other similar arrangements. The remaining assets and liabilities of Conrail, including joint facilities, generally will either be shared or allocated ratably between the Company and NSC according to their Percentages. In arriving at the proposed division of Conrail and their Percentages, the Company and NSC negotiated with a view toward producing the best fits with their existing systems and optimizing service to their respective customers. The maps reprinted on the front inside cover and back inside cover of this Prospectus show, respectively, the proposed post- Transaction (as defined below) CSXT route system and the approximate division of Conrail's routes as contemplated by the CSX/NSC Agreement. These maps are included for illustrative purposes only and are qualified in their entirety by reference to the CSX/NSC Agreement. See "Incorporation of Certain Documents by Reference."

The acquisition by the Company of the Conrail Shares and the right to use the assets allocated to or shared by the Company pursuant to the CSX/NSC Agreement and the liabilities allocated to or shared by it pursuant to the CSX/NSC Agreement will be referred to in this Prospectus as the "Transaction." Many of the terms of the Transaction will be detailed in further definitive documentation that is currently being negotiated between CSX and NSC (the "Definitive Documentation").

For additional information regarding the Transaction and the CSX/NSC Agreement, reference is made to the Company's Tender Offer Statement on Schedule 14D-1, together with exhibits thereto, initially filed with the Commission on December 6, 1996, as amended.

Financing Arrangements

The Company spent approximately $2.2 billion to purchase its portion of the outstanding Shares pursuant to the Joint Tender Offer and the merger. The Company previously paid approximately $2 billion to acquire about 20% of Conrail's shares in November 1996. At that time, the Company arranged a five- year $4.8 billion bank credit facility (the "Credit Agreement") to finance an acquisition of Conrail and to meet general working capital needs. The Company used the majority of the net proceeds from the sale of the Old Debentures to finance the balance of its contribution under the Joint Tender Offer and the merger. On May 6, 1997, in connection with the consummation of the sale of Old Debentures, the Company reduced by $2.3 billion the lenders' commitments under the Credit Agreement. See "Capitalization."

Such financings have resulted in the Company's having outstanding a combination of long-term debt with staggered maturities and commercial paper. The Company expects its long-term debt levels (including the Company's portion of Conrail debt) to peak in 1998 at approximately $6.8 billion, with related interest charges (including interest payments on the Company's portion of Conrail debt) to peak at approximately $520.0 million. While the Definitive Documentation is not complete, the Company and NSC contemplate that payments to Conrail under operating or similar arrangements and through capital contributions to the Acquisition Entity will be sufficient to pay obligations on Conrail's outstanding debt instruments in accordance with their terms, or to refinance such obligations, as appropriate. The Company and NSC have agreed in the CSX/NSC Agreement that such debt will be shared ratably according to their Percentages.

BENEFITS OF THE TRANSACTION

Broadest Geographic Network in Eastern United States

The Transaction will significantly enhance the Company's position as a leading global transportation company. The Company will remain the largest railroad in the eastern United States and become the third largest railroad in the nation, measured in terms of route miles and ton-miles. The Company, as a result of the Transaction, will be adding approximately 3,500 route miles, or 19%, to its rail network, and sharing with NSC approximately 1,200 additional route miles. The Company will have approximately 22,000 route miles in 22 states, the District of Columbia and the Provinces of Ontario and Quebec, Canada, and will provide direct access to virtually every major metropolitan area east of the Mississippi River and to eleven of the largest east coast and gulf ports.

13

Enhanced Operating Efficiencies and Revenue Growth

Management expects the integration of Conrail operations resulting from the Transaction to add approximately $1.6 billion, or 15%, to the Company's annual revenue beginning in the first twelve months following the Control Date. Management believes that the Transaction will also result in growth of the Company's rail revenue base through expansion of single-line service and the Company's ability to compete more effectively on certain routes along which large quantities of goods are now transported by truck. Single-line service is preferred by shippers over joint-line service because of lower transaction costs, reduced delays, less damage from interchange operations and single- carrier accountability. The addition of Conrail lines to the Company's rail network also will improve operational efficiency through better asset utilization. Optimization of train sizes, increased length of haul, improved backhauls, shorter routes to many destinations and fewer empty movements are all expected to produce cost reductions for the combined rail network. Other significant savings will be achieved through the realization of economies of scale, rationalization of administrative and other overhead expenses and consolidation of duplicative facilities.

Financial Effects

The Company expects that the benefits from the Transaction will begin to build from the Control Date and should be largely realized within a three-year period thereafter. Therefore, for the purposes of the following discussion, Year 1, Year 2 and Year 3 correspond to the three consecutive 12-month periods following the Control Date. Based on joint efforts of the Company and Conrail to identify potential cost savings, management currently estimates that the Transaction will lead to quantifiable pretax benefits from increased traffic and cost efficiencies of approximately $75 million, $170 million and $240 million annually in Years 1, 2 and 3, respectively, compared to the separate operation of the Company and its share of Conrail. These benefits include estimated incremental operating income of $25 million, $54 million and $75 million expected through increased traffic in Years 1, 2 and 3, respectively. The remaining pretax benefits will be in the form of operating cost savings, with $50 million, $116 million and $165 million expected to be realized in Years 1, 2 and 3, respectively. Further, management expects a reduction in the requirement for annual capital expenditures of approximately $12 million, $28 million and $40 million in Years 1, 2 and 3, respectively. Management estimates that the Company will, in Years 1 and 2, incur one-time transition capital expenditures in connection with the integration of operations. Those are expected to be $310 million in Year 1 and $178 million in Year 2. The Company is continuing to evaluate the foregoing estimates, some or all of which may be refined in the joint application to be filed with the STB.

The overall purchase price, including transaction costs, paid by the Company is expected to exceed the historical net book value of the Company's share of the underlying Conrail assets by approximately $2.9 billion. Although purchase accounting adjustments will not be finalized until the Transaction is completed, a substantial portion of the excess purchase price is expected to be allocated to specific net assets and amortized over the remaining useful lives of those assets. The remainder of the excess purchase price will be allocated to goodwill and amortized over 40 years.

Because of the time required to obtain necessary regulatory and other approvals, the Company does not expect integrated operations to have a significant effect on operating and financial results prior to fiscal 1998. The primary impact of the proposed Transaction on net earnings prior to the integration of operations is likely to be the after-tax effect of the Company's share of Conrail's net earnings, reported under the equity method of accounting, less amortization of the excess purchase price and interest on debt incurred to acquire Conrail shares. Net cash flow prior to operational integration is expected to be reduced by interest payments on such debt. The average interest rate in 1996 on debt incurred to acquire Conrail shares was approximately 5.6%. The degree of negative impact on net earnings or net cash flow during 1997 will be significantly affected by the net earnings reported by Conrail and the average interest rate and timing of interest payments on the related debt.

THE ABOVE ESTIMATES AND FORECASTS ARE BASED UPON NUMEROUS ESTIMATES AND

USE OF PROCEEDS

The Company will not receive any proceeds from the Exchange Offers. On May 6, 1997, the Company issued $350,000,000 principal amount of Old 2002 Debentures, $300,000,000 principal amount of Old 2004 Debentures, $450,000,000 principal amount of Old 2007 Debentures, $400,000,000 principal amount of Old 2017 Debentures, $500,000,000 principal amount of Old 7.95% 2027 Debentures, $100,000,000 principal amount of Old 6.95% 2027 Debentures and $250,000,000 principal amount of Old 7.25% 2027 Debentures, and on May 8, 1996 the Company issued $150,000,000 principal amount of Old 2032 Debentures (together, the "Offering"). The Old Debentures were sold by the Company to Salomon Brothers Inc, Credit Suisse First Boston Corporation, Chase Securities Inc., Goldman, Sachs & Co., Morgan Stanley & Co. Incorporated and NationsBanc Capital Markets, Inc. (the "Initial Purchasers") and were in turn sold by the Initial Purchasers to a limited number of qualified institutional buyers and accredited investors pursuant to Rule 144A and Regulation D, respectively, under the Securities Act and exemptions from applicable state securities laws, and the Offering was not subject to the registration requirements of the Securities Act and applicable state securities laws. The net proceeds from the sale of the Old Debentures sold in the Offering primarily were used to fund a portion of the Company's obligations under the CSX/NSC Agreement, including the purchase of Conrail Shares pursuant to the Joint Tender Offer and the merger. The balance of the net proceeds were used for general corporate purposes, including, without limitation, repayment of borrowings, working capital and capital expenditures. See "The Company--Joint CSX/NSC Acquisition of Conrail."

(1) Commercial paper borrowings of $2.3 billion, including approximately $2.0 billion incurred to acquire a 19.9% investment in Conrail, were classified as long-term debt at March 28, 1997 based on the Company's ability and intent to maintain this debt outstanding for more than one year. Approximately $2.2 billion of the proceeds from the issuance of the Old Debentures was used to fund the Company's obligation under the Joint Tender Offer and the merger, and the remaining $300 million was used to reduce long-term commercial paper borrowings.

CONSOLIDATED RATIO OF EARNINGS TO FIXED CHARGES
AND SELECTED FINANCIAL RATIO

The Company's consolidated ratio of earnings to fixed charges and ratio of total long-term debt to total capitalization for each of the fiscal periods indicated are as follows:

(a) For purposes of computing the ratio of earnings to fixed charges, earnings represent earnings (loss) before income taxes plus interest expense on indebtedness, amortization of debt discount, the interest portion of fixed rent expense, undistributed earnings of unconsolidated subsidiaries and minority interest expense. Fixed charges include interest on indebtedness (whether expensed or capitalized), amortization of debt discount and the interest portion of fixed rent expense.
(b) Operating income includes a charge of $257 million to recognize the estimated costs of initiatives to revise, restructure and consolidate specific operations and administrative functions at the Company's rail and container-shipping units. Excluding the impact of the charge, the ratio of earnings to fixed charges would have been 3.7x.
(c) Operating income includes a charge of $93 million to recognize the estimated costs of restructuring certain operations and functions at the Company's container-shipping unit. Excluding the impact of the charge, the ratio of earnings to fixed charges would have been 2.5x.
(d) Operating income includes a charge of $699 million to recognize the estimated costs of buying out certain trip-based compensation elements paid to train crews at the Company's rail unit. Excluding the impact of the charge, the ratio of earnings to fixed charges would have been 2.5x.

FISCAL QUARTER ENDED:

Mar. 28, 1997--  The Company incurred net costs before income taxes of $24
                 million with respect to its investment in Conrail common stock.
                 These net costs, principally interest on debt issued to acquire
                 the investment less dividends received on the stock, reduced
                 net earnings by $16 million, seven cents per share.

FISCAL YEARS ENDED:

Dec. 29, 1995--  Operating income includes a charge of $257 million to recognize
                 the estimated costs of initiatives to revise, restructure and
                 consolidate specific operations and administrative functions at
                 its rail and container-shipping units. The restructuring charge
                 reduced net earnings by $160 million, 76 cents per share. The
                 Company also recognized a net investment gain of $77 million,
                 $51 million after tax, 24 cents per share, on the issuance of
                 an equity interest in a Sea-Land terminal and related
                 operations in Asia and the write-down of various investments.

Dec. 30, 1994--  Net earnings includes an accelerated pretax gain of $69
                 million, $42 million after tax, 20 cents per share on the
                 satisfaction by the state of Florida of its remaining unfunded
                 obligation issued in 1988 to consummate the purchase of 80
                 miles of track and right of way.

                                      18

Dec. 31, 1993--  Operating income includes a charge of $93 million to recognize
                 the estimated costs of restructuring certain operations and
                 functions at the Company's container-shipping unit. The
                 restructuring charge reduced net earnings by $61 million, 30
                 cents per share. Net earnings also includes charges of $56
                 million, 26 cents per share, relating to the revision of the
                 Company's estimated annual effective tax rate to reflect the
                 change in the federal statutory income tax rate from 34% to
                 35%.

Dec. 31, 1992--  Operating income includes a charge of $699 million to recognize
                 the estimated costs of buying out certain trip-based
                 compensation elements paid to train crews. The charge reduced
                 net earnings by $450 million, $2.19 per share.

RESTATEMENT:

Beginning with the quarter ended June 28, 1996, the Company changed its earnings presentation to exclude non-transportation activities from operating revenue and expense. These activities, principally real estate and resort operations, are now included in other income. Amounts for periods prior to June 28, 1996 have been restated to conform to the revised presentation.

All per share data for periods prior to December 21, 1995 have been adjusted for the two- for-one common stock split distributed to shareholders on that date.

QUARTER ENDED MARCH 31,

1997--  Operating income includes merger-related costs of $22 million. These
        costs reduced net income by $14 million and earnings per share ("EPS")
        17 cents on a primary basis and 16 cents on a fully diluted basis.

YEARS ENDED DECEMBER 31,

1996--  Operating income includes a charge of $135 million for voluntary
        separation programs, which reduced net income by $83 million and EPS
        $1.07 on a primary basis and 95 cents on a fully diluted basis.
        Operating income also includes merger-related costs of $16 million,
        which reduced net income by $10 million and EPS by 13 cents on a primary
        basis and 11 cents on a fully-diluted basis.


1995--  Operating income includes an asset disposition charge of $285 million
        for rail lines and other assets written down to estimated net realizable
        value, which reduced net income by $176 million and EPS $2.24 on a
        primary basis and $1.98 on a fully diluted basis. Net income also
        includes a one-time $21 million benefit related to a decrease in a state
        income tax rate which increased EPS 27 cents on a primary basis and 23
        cents on a fully diluted basis.

20

1994--  Included in operating income is a charge of $84 million ($51 million
        after tax benefits) for a voluntary early retirement program and
        related costs. This reduced EPS 64 cents on a primary basis and 57
        cents on a fully diluted basis.


1993--  Net income includes charges of $74 million as a result of the adoption
        of required changes in accounting for income taxes and postretirement
        benefits other than pensions which reduced EPS 92 cents on a primary
        basis and 81 cents on a fully diluted basis; $50 million ($80 million
        before tax benefit of $30 million) for the disposition of a subsidiary
        which decreased EPS 62 cents on a primary basis and 55 cents on a
        fully diluted basis; and $34 million for the increase in the federal
        corporate income tax rate which decreased EPS 42 cents on a primary
        basis and 37 cents on a fully diluted basis.

UNAUDITED PRO FORMA FINANCIAL STATEMENTS

On May 23, 1997, the Joint Tender Offer for the Conrail Shares expired. As a result of the contribution by the Company and NSC of Conrail shares owned by them before the Joint Tender Offer as well as the contribution of funds to complete the Joint Tender Offer and the merger, they have, respectively, a 42 percent and a 58 percent economic interest in the Acquisition Entity which now owns all of the Conrail shares. Such shares are being held in a voting trust pending STB approval. The Company and NSC also each may exercise a 50 percent voting interest in the Acquisition Entity and each has the right to appoint half of that entity's directors and a full-time Co-Chief Executive Officer. Under the CSX/NSC Agreement, subject to STB approval, the Company will operate routes and assets (or rights thereto) that generated approximately 42 percent of Conrail's 1995 revenues.

The Unaudited Pro Forma Financial Statements included herein present a Condensed Consolidated Statement of Financial Position for the Company as of March 28, 1997, and Condensed Consolidated Statements of Earnings for the fiscal quarter ended March 28, 1997, and the fiscal year ended December 27, 1996. The pro forma financial statements reflect (i) the completion by the Company and NSC of their Joint Tender Offer for the Conrail Shares and the merger at $115 per share through the Acquisition Entity; and (ii) the related borrowings by the Company, including the Debentures.

These events are reflected in the Pro Forma Condensed Consolidated Statement of Financial Position as if they had occurred on March 28, 1997, and in the Pro Forma Condensed Consolidated Statements of Earnings as if they had occurred at the beginning of the period presented. The financial information for Conrail was based upon its historical financial statements for the quarter ended March 31, 1997, and for the year ended December 31, 1996, as reported in its Form 10-Q and Form 10-K, respectively. Conrail's 1996 results included a special charge of $135 million (pre-tax) for voluntary separation programs.

The Company is using the equity method of accounting for its interest in Conrail following consummation of the Joint Tender Offer and the merger and continuing as long as the Conrail shares are held in the voting trust--a period that will extend at least until the effective date of the STB's decision approving the transactions contemplated by the CSX/NSC Agreement (if such approval is obtained). In accordance with Accounting Principles Board ("APB") Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock," the excess of the Company's purchase price over the underlying net assets acquired ("Excess") is being amortized. Based on a preliminary analysis of the fair value of the underlying net assets of Conrail, the Company believes a significant portion of the Excess will be allocated to long-lived assets other than goodwill. Further information as to the values of assets and liabilities, as well as specific allocations to the Company or NSC, may affect these preliminary estimates.

The method of accounting for the investment in Conrail subsequent to dissolution of the voting trust will depend on the final terms of the ownership arrangement between the Company and NSC approved by the STB. Additionally, the ultimate terms of leases, operating partnerships and other arrangements will affect the accounting. It is also expected that some of the assets and operations of Conrail will remain subject to joint control by the Company and NSC and, thus, will continue to be accounted for using the equity method of accounting even after STB approval.

The unaudited pro forma financial statements do not reflect synergies and, accordingly, do not account for any potential increases in operating income, any estimated cost savings, any adjustments to conform accounting practices or any capital expenditures to be realized or made by either the Company or Conrail to achieve such improvements. THE UNAUDITED PRO FORMA FINANCIAL STATEMENTS ARE PREPARED FOR ILLUSTRATIVE PURPOSES ONLY AND ARE NOT NECESSARILY INDICATIVE OF THE FINANCIAL POSITION OR RESULTS OF OPERATIONS THAT MIGHT HAVE OCCURRED HAD THE APPLICABLE TRANSACTIONS ACTUALLY TAKEN PLACE ON THE DATE INDICATED, OR OF FUTURE RESULTS OF OPERATIONS OR FINANCIAL POSITION OF THE STANDALONE OR COMBINED ENTITIES.

The unaudited pro forma financial statements are based on the historical consolidated financial statements of the Company and Conrail and should be read in conjunction with such historical financial statements and the notes thereto.

NOTE 1. PRELIMINARY CALCULATION OF PURCHASE PRICE

Pursuant to the CSX/NSC Agreement, CSX has invested approximately $4.156 billion (including $1.955 billion expended in November 1996, and excluding transaction costs) to acquire, through its ownership interest in Conrail, various Conrail routes and assets or rights thereto. The acquisition was financed with a combination of debentures and commercial paper. The purchase price has been preliminarily calculated as follows:

(a) Exclusive of 85,000 shares previously sold by CSX at an average price of $98.983 per share.

NOTE 2. DEBT

Long-term debt has been increased by $2.2 billion and short-term debt has been increased by $0.1 billion to reflect the net additional borrowing subsequent to March 28, 1997 to finance the Company's purchase price (including transaction fees and debt issuance costs) in excess of the $1.955 billion previously paid. This net additional borrowing is inclusive of the proceeds of the $2.5 billion of Debentures, reduced by net repayments of commercial paper previously outstanding. As a consequence of the Company's first tender offer and its share of the subsequent Joint Tender Offer and merger, short-term and long-term debt of $4.256 billion is outstanding, as follows:

                                                  ======

Pro forma interest expense has been increased as a result of the additional debt incurred, as noted below. Debt placement fees, debt discount and related costs are being amortized on the interest method and, together

26

with annual commitment fees, approximate $7 million in the first year after consummation of the Joint Tender Offer. Inclusive of these costs, the effective interest rate is approximately 6.95%. If interest rates assumed were to change by one-eighth of one percent, the pro forma interest expense on variable rate debt associated with the transaction would vary by $2 million annually.

NOTE 3. OTHER INCOME

The equity method of accounting will be applied to the Company's investment in Conrail throughout the period the investment is held in the voting trust. In accordance with APB Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock," other income includes 42% of Conrail's historical net income, adjusted for amortization, net of tax, of the difference between the Company's investment in Conrail and 42% of Conrail's underlying equity in net assets. The difference is primarily attributable to the estimated fair value of property and equipment, net of the related deferred taxes, and includes approximately $757 million in goodwill. This allocation is based on preliminary estimates of fair values of all Conrail assets and liabilities and is likely to change after the Definitive Documentation is finalized and regulatory approvals are obtained. To the extent that specific assets and liabilities are allocated to Conrail entities over which the Company will have a controlling financial interest, the allocation will be redesignated to follow the method in which the investment is accounted for subsequent to the approval by the STB. The preliminary estimates are also likely to change as additional information concerning fair values and remaining useful lives becomes available. An appraisal of the assets is currently underway. The Company intends to amortize any goodwill resulting from the purchase over a period of 40 years. Adjustments to property and equipment are depreciated over their estimated remaining useful lives, which range from 2 to 102 years.

NOTE 5. UNUSUAL EVENTS

As described in Note 3, pro forma amounts reflected in the Pro Forma Condensed Consolidated Statements of Earnings were calculated and presented in accordance with the equity method of accounting. If the effects of 42% of Conrail's after-tax merger-related costs of $14 million had been excluded for the fiscal quarter ended March 28, 1997, pro forma net earnings and pro forma earnings per share would have been $128 million and 59 cents, respectively. If the effects of 42% of Conrail's one-time after-tax charge of $83 million related to voluntary separation programs and after-tax merger-related costs of $10 million had been excluded for the fiscal year ended December 27, 1996, pro forma net earnings and pro forma earnings per share would have been $775 million and $3.63, respectively.

NOTE 6. SUMMARIZED CONSOLIDATED CONRAIL FINANCIAL DATA

Because of the numerous agreements that must be negotiated and completed, and because STB approval must be obtained, it is not possible to present some or most of the Company's investment in Conrail based on separate assets, liabilities and operations. However, the Company has a 42% economic interest in the entity formed to acquire Conrail Shares. It is expected that in some form, yet to be finally determined, the Company will have a primary operating interest in the routes and facilities, as described more fully in "The Company--Joint CSX/NSC Acquisition of Conrail". The following historical Conrail financial data, as of and for the quarter ended March 31, 1997 and the year ended December 31, 1996, respectively, is presented to facilitate an understanding of the Company's ultimate economic interest in Conrail:

THE EXCHANGE OFFERS

The Old Debentures were sold by the Company on May 6, 1997 (except for the Old 2032 Debentures which were sold on May 8, 1997) to the Initial Purchasers, who in turn sold the Old Debentures to a limited number of qualified institutional buyers and accredited investors pursuant to Rule 144A and Regulation D, respectively, under the Securities Act. In connection with the sale of the Old Debentures, the Company and the Initial Purchasers entered into a registration rights agreement dated as of May 6, 1997 (the "Registration Rights Agreement"), which requires the Company to file with the Commission a registration statement under the Securities Act with respect to the New Debentures of the Company, which are identical in all material respects to the Old Debentures, and to use its best efforts to cause such registration statement to become effective under the Securities Act. The Company is further obligated, upon the effectiveness of that registration statement, to offer the holders of the Old Debentures the opportunity to exchange their Old Debentures for a like principal amount of New Debentures, which will be issued without a restrictive legend and may be reoffered and resold by the holder without restrictions or limitations under the Securities Act. In the event certain circumstances occur which would result in either the New Debentures not becoming freely tradeable or certain holders of the Old Debentures not being eligible to participate in the Exchange Offer, then the Company is required to file a Shelf Registration Statement and use its best efforts to cause the Old Debentures to be registered under the Securities Act. A copy of the Registration Rights Agreement has been filed as an exhibit to the Registration Statement of which this Prospectus is a part. The Exchange Offers are being made pursuant to the Registration Rights Agreement to satisfy the Company's obligations thereunder. The term "Holder" with respect to the Exchange Offers means any person in whose name Old Debentures are registered on the security registrar's books or any other person who has obtained a properly completed assignment from the registered holder or any participant in the DTC system whose name appears on a security position listing as the holder of such Old Debentures and who desires to deliver such Old Debentures by book- entry transfer at DTC. See "Description of the New Debentures--Registration Rights Agreement."

Upon the terms and subject to the conditions set forth in this Prospectus and in the accompanying Letter of Transmittal (which together constitute the Exchange Offers), the Company will accept for exchange Old Debentures which are properly tendered on or prior to the Expiration Date and not withdrawn as permitted below. As used herein, the term "Expiration Date" means 5:00 p.m., New York City time, on , 1997; provided, however, that if the Company, in its sole discretion, has extended the period of time during which any or all of the Exchange Offers are open, the term "Expiration Date" means the latest time and date to which the applicable Exchange Offer is extended.

As of the date of this Prospectus, $350,000,000 aggregate principal amount of the Old 2002 Debentures, $300,000,000 aggregate principal amount of the Old 2004 Debentures, $450,000,000 aggregate principal amount of the Old 2007 Debentures, $400,000,000 aggregate principal amount of the Old 2017 Debentures, $500,000,000 aggregate principal amount of the Old 7.95% 2027 Debentures, $100,000,000 aggregate principal amount of the Old 6.95% 2027 Debentures, $250,000,000 aggregate principal amount of the Old 7.25% 2027 Debentures, and $150,000,000 aggregate principal amount of the Old 2032 Debentures, are outstanding. This Prospectus, together with the Letter of Transmittal, is first being sent on or about , 1997 to all Holders of Old Debentures known to the Company. The Company's obligation to accept Old Debentures for exchange pursuant to the Exchange Offers is subject to certain customary conditions as set forth under "--Certain Conditions to the Exchange Offers" below.

The Company expressly reserves the right, at any time or from time to time, to extend the period of time during which any or all of the Exchange Offers are open, and thereby delay acceptance for exchange of any Old Debentures, by giving oral or written notice of such extension to the Holders thereof as described below. During any such extension, all Old Debentures previously tendered will remain subject to the Exchange Offers and may be accepted for exchange by the Company. Any Old Debentures not accepted for exchange for any reason will be returned without expense to the tendering Holder thereof as promptly as practicable after the expiration or termination of the Exchange Offers.

30

Old Debentures tendered in the Exchange Offers must be in denominations of principal amount of $1,000 or any integral multiple thereof.

The Company expressly reserves the right to amend or terminate any or all of the Exchange Offers, and not to accept for exchange any Old Debentures not theretofore accepted for exchange, upon the occurrence of any of the conditions of the Exchange Offers specified below under "--Certain Conditions to the Exchange Offers." The Company will give oral or written notice of any extension, amendment, non-acceptance or termination to the Holders of the Old Debentures as promptly as practicable, such notice in the case of any extension to be issued by means of a press release or other public announcement no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

PROCEDURES FOR TENDERING OLD DEBENTURES

Only a Holder of Old Debentures may tender such Old Debentures in the Exchange Offers. The tender to the Company of Old Debentures by a Holder thereof as set forth below and the acceptance thereof by the Company will constitute a binding agreement between the tendering Holder and the Company upon the terms and subject to the conditions set forth in this Prospectus and in the accompanying Letter of Transmittal. A Holder who wishes to tender Old Debentures for exchange pursuant to any or all of the Exchange Offers must transmit a properly completed and duly executed Letter of Transmittal, including all other documents required by such Letter of Transmittal, to The Chase Manhattan Bank (the "Exchange Agent") at the address set forth below under "--Exchange Agent" or (in the case of a book-entry transfer) an Agent's Message in lieu of the Letter of Transmittal on or prior to the Expiration Date. In addition, either (i) certificates for such Old Debentures must be received by the Exchange Agent along with the Letter of Transmittal, (ii) a timely confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such Old Debentures, if such procedure is available, into the Exchange Agent's account at The Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedure for book-entry transfer described below, must be received by the Exchange Agent prior to the Expiration Date, or (iii) the Holder must comply with the guaranteed delivery procedures described below (see "--Guaranteed Delivery Procedures").

THE METHOD OF DELIVERY OF OLD DEBENTURES, LETTERS OF TRANSMITTAL AND ALL

OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE HOLDERS. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTERS OF TRANSMITTAL OR CERTIFICATES FOR OLD DEBENTURES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OF OTHER NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.

The term "Agent's Message" means a message, transmitted by the Book-Entry Transfer Facility to and received by the Exchange Agent and forming a part of a Book-Entry Confirmation, which states that DTC has received an express acknowledgment from the tendering participant, which acknowledgment states that such participant has received and agrees to be bound by the Letter of Transmittal and that the Company may enforce the Letter of Transmittal against such participant.

Any beneficial owner whose Old Debentures are registered in the name of a broker, dealer, commercial bank, trust company, or other nominee and who wishes to tender should contact the registered Holder promptly and instruct such registered Holder to tender on such beneficial owner's behalf. If such beneficial owner wishes to tender on such owner's own behalf, such owner must, prior to completing and executing the Letter of Transmittal and delivering such owner's Old Debentures, either make appropriate arrangements to register ownership of the Old Debentures in such beneficial owner's name or obtain a properly completed bond power from the registered Holder. The transfer of registered ownership may take considerable time.

31

Signatures on a Letter of Transmittal or a notice of withdrawal described below (see "--Withdrawal Rights"), as the case may be, must be guaranteed (see "--Guaranteed Delivery Procedures") unless the Old Debentures surrendered for exchange pursuant thereto are tendered (i) by a registered Holder of the Old Debentures who has not completed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or (ii) for the account of an Eligible Institution (as defined below). In the event that signatures on a Letter of Transmittal or a notice of withdrawal, as the case may be, are required to be guaranteed, such guarantees must be by a financial institution (including most banks, savings and loan associations and brokerage houses) that is a participant in the Securities Transfer Agents Medallion Program, the New York Stock Exchange Medallion Program or the Stock Exchanges Medallion Program (collectively, "Eligible Institutions"). If Old Debentures are registered in the name of a person other than a signer of the Letter of Transmittal, the Old Debentures surrendered for exchange must be endorsed by or be accompanied by a written instrument or instruments of transfer or exchange, in satisfactory form as determined by the Company in its sole discretion, duly executed by the registered Holder exactly as the name or names of the registered Holder or Holders appear on the Old Debentures with the signature thereon guaranteed by an Eligible Institution.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance of Old Debentures tendered for exchange will be determined by the Company in its sole discretion, which determination shall be final and binding. The Company reserves the absolute right to reject any and all tenders of any particular Old Debentures not properly tendered or not to accept any particular Old Debentures which acceptance might, in the judgment of the Company or its counsel, be unlawful. The Company also reserves the absolute right to waive any defects or irregularities or conditions of the Exchange Offers as to any particular Old Debentures either before or after the Expiration Date (including the right to waive the ineligibility of any Holder who seeks to tender Old Debentures in the Exchange Offers). The interpretation of the terms and conditions of the Exchange Offers as to any particular Old Debentures either before or after the Expiration Date (including the Letter of Transmittal and the instructions thereto) by the Company shall be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of Old Debentures for exchange must be cured within such reasonable period of time as the Company shall determine. None of the Company, the Exchange Agent or any other person shall be under any duty to give notification of any defect or irregularity with respect to any tender of Old Debentures for exchange, nor shall any of them incur any liability for failure to give such notification.

If the Letter of Transmittal or any Old Debentures or powers of attorney are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such person should so indicate when signing and, unless waived by the Company, proper evidence satisfactory to the Company of their authority to so act must be submitted with the Letter of Transmittal.

By tendering, each Holder will represent to the Company that, among other things, the New Debentures acquired pursuant to the Exchange Offers are being obtained in the ordinary course of business of the person receiving such New Debentures, whether or not such person is the Holder, and that neither the Holder nor such other person has any arrangement or understanding with any person to participate in the distribution of the New Debentures. If any Holder or any such other person is an "affiliate," as defined under Rule 405 of the Securities Act, of the Company or is engaged in or intends to engage in, or has an arrangement or understanding with any person to participate in, a distribution of such New Debentures to be acquired pursuant to the Exchange Offers, such Holder or any such other person (i) may not rely on the applicable interpretation of the staff of the Commission and (ii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. Each broker-dealer that receives New Debentures for its own account in exchange for Old Debentures, where such Old Debentures were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Debentures. See "Plan of Distribution." The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

32

ACCEPTANCE OF OLD DEBENTURES FOR EXCHANGE; DELIVERY OF NEW DEBENTURES

Upon satisfaction or waiver of all of the conditions to the Exchange Offers, the Company will accept on, or promptly after, the Expiration Date, all Old Debentures properly tendered and will issue the New Debentures promptly after acceptance of the Old Debentures. See "--Certain Conditions to the Exchange Offers" below. For purposes of the Exchange Offers, the Company will be deemed to have accepted properly tendered Old Debentures for exchange when, as and if the Company has given oral (promptly confirmed in writing) or written notice thereof to the Exchange Agent.

For each Old Debenture accepted for exchange, the Holder of such Old Debenture will receive as set forth below under "Description of the New Debentures--Book-Entry, Delivery and Form" a New Debenture having a principal amount equal to that of the surrendered Old Debenture. Accordingly, registered Holders of New Debentures on the relevant record date for the first interest payment date following the consummation of the Exchange Offers will receive interest accruing from the most recent date to which interest has been paid on the Old Debentures or, if no interest has been paid, from May 1, 1997. Old Debentures accepted for exchange will cease to accrue interest from and after the date of consummation of the Exchange Offers. Holders whose Old Debentures are accepted for exchange will not receive any payment in respect of accrued interest on such Old Debentures otherwise payable on any interest payment date the record date for which occurs on or after consummation of the Exchange Offers. In the event that (i) by November 2, 1997 (or November 4, 1997 with respect to the Old 2032 Debentures), neither the Exchange Offer Registration Statement is declared effective nor (if the Exchange Offers are not permitted as described above) the Shelf Registration Statement is filed with the Commission, or (ii) by December 2, 1997 (or December 4, 1997 with respect to the Old 2032 Debentures), one or more of the Exchange Offers with respect to any series of Debentures is not consummated or the Shelf Registration Statement is not declared effective with respect thereto (each such event referred to in clauses (i) or (ii), a "Registration Default"), interest will accrue on the applicable Old Debentures (in addition to stated interest on such Old Debentures) from and including the next day following each such Registration Default. In each case such additional interest (the "Special Interest") will be payable in cash semiannually in arrears each May 1 and November 1, at a rate per annum equal to 0.25% of the principal amount of such Old Debentures for each such Registration Default. The aggregate amount of Special Interest payable pursuant to the above provisions will in no event exceed 0.25% per annum of the principal amount of such Old Debentures. Upon
(a) the effectiveness of the Exchange Offer Registration Statement or the filing of the Shelf Registration Statement after the date set forth in clause
(i) above or (b) the consummation of the Exchange Offer for such Old Debentures or the effectiveness of a Shelf Registration Statement, as the case may be, after the date set forth in clause (ii) above, the Special Interest payable on such Old Debentures as a result of the applicable Registration Default will cease to accrue.

In all cases, issuance of New Debentures for Old Debentures that are accepted for exchange pursuant to the Exchange Offers will be made only after timely receipt by the Exchange Agent of certificates for such Old Debentures or a timely Book-Entry Confirmation of such Old Debentures into the Exchange Agent's account at the Book-Entry Transfer Facility, a properly completed and duly executed Letter of Transmittal or an Agent's Message in lieu thereof and all other required documents. If any tendered Old Debentures are not accepted for any reason set forth in the terms and conditions of the Exchange Offers or if Old Debentures are submitted for a greater principal amount than the Holder desires to exchange, such unaccepted or non-exchanged Old Debentures will be returned without expense to the tendering Holder thereof (or, in the cases of Old Debentures tendered by book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry procedures described below, such non-exchanged Old Debentures will be credited to an account maintained with such Book-Entry Transfer Facility) as promptly as practicable after the expiration or termination of the Exchange Offers.

BOOK-ENTRY TRANSFER

The Exchange Agent will make a request to establish an account with respect to the Old Debentures at the Book-Entry Transfer Facility for purposes of the Exchange Offers within two business days after the date of this

Prospectus unless the Exchange Agent already has established an account with the Book-Entry Transfer Facility suitable for the Exchange Offers, and any financial institution that is a participant in the Book-Entry Transfer Facility's systems may make book-entry delivery of Old Debentures by causing the Book-Entry Transfer Facility to transfer such Old Debentures into the Exchange Agent's account at the Book-Entry Transfer Facility in accordance with such Book-Entry Transfer Facility's procedures for transfer. However, although delivery of Old Debentures may be effected through book-entry transfer at the Book-Entry Transfer Facility, the Letter of Transmittal or a facsimile thereof, with any required signature guarantees or an Agent's Message in lieu thereof and any other required documents, must, in any case, be transmitted to and received by the Exchange Agent at the address set forth below under "--Exchange Agent" on or prior to the Expiration Date or the guaranteed procedures described below must be complied with.

GUARANTEED DELIVERY PROCEDURES

If a registered Holder of the Old Debentures desires to tender such Old Debentures and time will not permit such Holder's Old Debentures or other required documents to reach the Exchange Agent before the Expiration Date, or the procedure for book-entry transfer cannot be completed on a timely basis, a tender may be effected if (i) the tender is made through an Eligible Institution, (ii) on or prior to 5:00 p.m., New York City time, on the Expiration Date, the Exchange Agent receives from such Eligible Institution a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form provided by the Company (by telegram, telex, facsimile transmission, mail or hand delivery), setting forth the name and address of the Holder of Old Debentures and the amount of Old Debentures tendered, stating that the tender is being made thereby and guaranteeing that within three New York Stock Exchange ("NYSE") trading days after the date of execution of the Notice of Guaranteed Delivery, the certificates for all physically tendered Old Debentures, in proper form for transfer, or a Book- Entry Confirmation, as the case may be, together with a properly completed and duly executed Letter of Transmittal (or facsimile thereof or Agent's Message in lieu thereof) with any required signature guarantees and any other documents required by the Letter of Transmittal will be deposited by the Eligible Institution with the Exchange Agent, and (iii) the certificates for all physically tendered Old Debentures, in proper form for transfer, or a Book-Entry Confirmation, as the case may be, together with a properly completed and duly executed Letter of Transmittal (or facsimile thereof or Agent's Message in lieu thereof) with any required signature guarantees, and any other documents required by the Letter of Transmittal are deposited by the Eligible Institution within three NYSE trading days after the date of execution of the Notice of Guaranteed Delivery.

WITHDRAWAL RIGHTS

Tenders of Old Debentures may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date. For a withdrawal to be effective, a written notice or facsimile transmission notice of withdrawal must be received by the Exchange Agent at the address set forth below under "-- Exchange Agent." Any such notice of withdrawal must specify the name of the person having tendered the Old Debentures to be withdrawn, identify the Old Debentures to be withdrawn (including the principal amount of such Old Debentures), and (where certificates for Old Debentures have been transmitted) specify the name in which such Old Debentures are registered, if different from that of the withdrawing Holder. If certificates for Old Debentures have been delivered or otherwise identified to the Exchange Agent, then, prior to the release of such certificates the withdrawing Holder must also submit the serial numbers of the particular certificates to be withdrawn and a signed notice of withdrawal with signatures guaranteed by an Eligible Institution unless such Holder is an Eligible Institution in which case such guarantee will not be required. If Old Debentures have been tendered pursuant to the procedure for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Old Debentures and otherwise comply with the procedures of such facility. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by the Company, whose determination will be final and binding on all parties. Any Old Debentures so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the Exchange Offers. Any Old Debentures which have been

34

tendered for exchange but which are not exchanged for any reason will be returned to the Holder thereof without cost to such Holder (or, in the case of Old Debentures tendered by book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry transfer procedures described above, such Old Debentures will be credited to an account maintained with such Book-Entry Transfer Facility for the Old Debentures) as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offers. Properly withdrawn Old Debentures may be retendered by following one of the procedures described under "--Procedures for Tendering Old Debentures" above at any time on or prior to the Expiration Date.

CERTAIN CONDITIONS TO THE EXCHANGE OFFERS

Notwithstanding any other provisions of the Exchange Offers, and subject to its obligations pursuant to the Registration Rights Agreement, the Company shall not be required to accept for exchange, or to issue New Debentures in exchange for, any Old Debentures and may terminate or amend any or all of the Exchange Offers, if at any time before the acceptance of such New Debentures for exchange, any of the following events shall occur:

(i) any injunction, order or decree shall have been issued by any court or any governmental agency that would prohibit, prevent or otherwise materially impair the ability of the Company to proceed with any of the respective Exchange Offers; or

(ii) the Exchange Offers will violate any applicable law or any applicable interpretation of the staff of the Commission.

The foregoing conditions are for the sole benefit of the Company and may be asserted by the Company in whole or in part at any time and from time to time upon advice of outside counsel. The failure by the Company at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and such right shall be deemed an ongoing right which may be asserted at any time and from time to time.

In addition, the Company will not accept for exchange any Old Debentures tendered and no New Debentures will be issued in exchange for any such Old Debentures, if at such time any stop order is threatened by the Commission or in effect with respect to the Registration Statement of which this Prospectus is a part or the qualification of the Indenture with respect to the New Debentures under the Trust Indenture Act of 1939, as amended.

The Exchange Offer is not conditioned on any minimum principal amount of Old Debentures being tendered for exchange.

DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE A VALID DELIVERY OF SUCH LETTER OF TRANSMITTAL.

FEES AND EXPENSES

The Company will not make any payment to brokers, dealers or others soliciting acceptances of the Exchange Offers.

The expenses to be incurred in connection with the Exchange Offers will be paid by the Company. Such expenses include registration fees, fees and expenses of the Exchange Agent and Trustee, accounting and legal fees and printing costs, among others.

TRANSFER TAXES

Holders who tender their Old Debentures for exchanges will not be obligated to pay any transfer taxes in connection therewith, except that Holders who instruct the Company to register New Debentures in the name of, or request that Old Debentures not tendered or not accepted in the Exchange Offers be returned to, a person other than the registered tendering Holder will be responsible for the payment of any applicable transfer tax thereon.

CONSEQUENCES OF FAILURE TO EXCHANGE OLD DEBENTURES

Holders of Old Debentures who do not exchange their Old Debentures for New Debentures pursuant to the Exchange Offers will continue to be subject to the provisions in the Old Debentures regarding transfer and exchange of the Old Debentures and the restrictions on transfer of such Old Debentures as set forth in the legend thereon as a consequence of the issuance of the Old Debentures pursuant to exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws. In general, the Old Debentures may not be offered or sold, unless registered under the Securities Act and applicable state securities laws. The Company does not currently anticipate that it will register under the Securities Act Old Debentures not tendered. See "Description of the New Debentures--Registration Rights Agreement."

Based on interpretations by the staff of the Commission, as set forth in no- action letters issued to third parties, the Company believes that New Debentures issued pursuant to the Exchange Offers in exchange for Old Debentures may be offered for resale, resold or otherwise transferred by Holders thereof (other than any such Holder which is an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such New Debentures are acquired in the ordinary course of such Holders' business and such Holders, other than broker-dealers, have no arrangement or understanding with any person to participate in the distribution of such New Debentures. However, the Commission has not considered the Exchange Offers in the context of a no-action letter and there can be no assurance that the staff of the Commission would make a similar determination with respect to the Exchange Offers as in such other circumstances. Each Holder, other than a broker-dealer, must acknowledge that it is not engaged in, and does not intend to engage in, a distribution of such New Debentures and has no arrangement or understanding to participate in a distribution of New Debentures. If any Holder is an affiliate of the Company or is engaged in or intends to engage in or has any arrangement or understanding with respect to the distribution of the New Debentures to be acquired pursuant to the Exchange Offers, such Holder (i) may not rely on the applicable interpretations of the staff of the Commission and (ii) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction. Each broker-dealer that receives New Debentures for its own account in exchange for Old Debentures pursuant to the Exchange Offers must acknowledge that such Old Debentures were acquired by such broker-dealer as a result of market-making activities or other trading activities and that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Debentures. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed

36

to admit that it is an "underwriter" within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Debentures received in exchange for Old Debentures where such Old Debentures were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that for a period of 180 days after the Expiration Date, it will make this Prospectus available to any broker-dealer for use in connection with any such laws of certain jurisdictions, if applicable, where the New Debentures may not be offered or sold unless they have been registered or qualified for sale in such jurisdictions or any exemption from registration or qualification is available and is complied with. The Company has agreed, pursuant to the Registration Rights Agreement, subject to certain limitations specified therein, to register or qualify the New Debentures for offer or sale under the securities laws of such jurisdictions as any Holder reasonably requests in writing. Unless a Holder so requests, the Company does not currently intend to register or qualify the sale of the New Debentures in any such jurisdictions.

37

DESCRIPTION OF NEW DEBENTURES

GENERAL

The Old Debentures were issued under the Indenture and the New Debentures also will be issued under the Indenture. Each series of Old Debentures and the corresponding series of New Debentures will be treated as a single series of securities under the Indenture. The following summary of certain provisions of the Indenture does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the Indenture, including the definitions of certain terms therein and those terms made a part thereof by the Trust Indenture Act of 1939, as amended. A copy of the Indenture is available from the Company upon request. Whenever defined terms of the Indenture not otherwise defined herein are referred to, such defined terms are incorporated herein by reference. The term "Debentures" means the New Debentures and the Old Debentures treated as a single class.

The Indenture does not limit the aggregate principal amount of securities that can be issued thereunder. Securities may be issued in one or more series as may be authorized from time to time by the Company. Ten series of securities, including the Debentures, are currently outstanding under the Indenture.

Payments of interest on the Debentures may be made at the option of the Company by check mailed to the registered holders thereof or, at the option of a holder, by wire transfer to an account maintained by the payee with a bank located in the United States designated by such holder.

The Debentures may be transferred or exchanged at an office or agency to be maintained by the Company, subject to the limitations provided in the Indenture, without the payment of any service charge, other than any tax or governmental charge payable in connection therewith. Each series of Debentures is issuable in denominations of $1,000 and multiples thereof.

All moneys deposited with the Trustee or any Paying Agent, or held by the Company, in trust for the payment of principal of or interest on any Debentures and remaining unclaimed at the end of two years after such principal or interest shall have become due and payable will be repaid to the Company, and the holders of such Debentures will thereafter look only to the Company for payment thereof.

PURCHASE AT OPTION OF HOLDER

Each holder of 6.95% 2027 Debentures and each holder of 7.25% 2027 Debentures will have the right to require the Company to repurchase all or a portion of such series of Debentures owned by such holder (the "Put Option") on May 1, 2002 and May 1, 2005, respectively (the "Put Option Exercise Date"), at a purchase price equal to 100% of the principal amount of such Debentures tendered by such holder plus accrued interest thereon. On and after the Put Option Exercise Date, interest will cease to accrue on such Debentures or any portion thereof tendered for repayment. On or before the Put Option Exercise Date, the Company shall deposit with a paying agent (or the Trustee) money sufficient to pay the principal of and any accrued interest on such Debentures to be tendered for repayment.

A holder must provide the Company with notice of such holder's intention to exercise the Put Option during the period from and including March 1, 2002 through and including April 1, 2002 (with respect to the 6.95% 2027 Debentures) and the period from and including March 1, 2005 through and including April 1, 2005 (with respect to the 7.25% 2027 Debentures). Such notice, once given, will be irrevocable unless waived by the Company.

The Company will comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act if required and will file Schedule 13E-4 or any other schedule if required thereunder in connection with any offer by the Company to purchase the 6.95% 2027 Debentures or the 7.25% 2027 Debentures.

RANKING

The Debentures will be senior securities of the Company and the indebtedness evidenced thereby will rank pari passu with all other unsubordinated and unsecured indebtedness of the Company.

CERTAIN COVENANTS AND AGREEMENTS OF THE COMPANY

The Indenture does not limit the amount of indebtedness or lease obligations that may be incurred by the Company and its subsidiaries. The Indenture does not contain provisions which would give holders of the Debentures the right to require the Company to repurchase their Debentures in the event of a decline in the credit rating of the Company's debt securities resulting from a takeover, recapitalization or similar restructuring.

Limitation on Liens on Stock or Indebtedness of Principal Subsidiaries

The Indenture provides that, with respect to the Debentures, the Company 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 Indenture or thereafter acquired, of any Principal Subsidiary, to secure any Obligation (other than the Debentures) of the Company, any Subsidiary or any other Person, without in any such case making effective provision whereby all of the outstanding Debentures (and other outstanding debt securities issued from time to time pursuant to the Indenture) shall be directly secured equally and ratably with such Obligation. This provision does not restrict any other property of the Company or its Subsidiaries. The 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, Sea-Land and ACL; and "Subsidiary" as a corporation a majority of the outstanding voting stock of which is owned, directly or indirectly, by the Company or one or more Subsidiaries, or by the Company and one or more Subsidiaries. The Indenture does not prohibit the sale by the Company or any Subsidiary of any stock or indebtedness of any Subsidiary.

Consolidation, Merger and Sale of Assets

The Indenture provides that the Company may, without the consent of the holders of any of the outstanding Debentures of a series, consolidate with, merge into or transfer its assets substantially as an entirety to any

41

corporation organized under the laws of any domestic or foreign jurisdiction, provided that (i) the successor corporation assumes the due and punctual payment of the principal of and interest on all debt securities issued under the Indenture and the performance of every covenant of the Indenture, (ii) immediately after giving effect thereto, no Event of Default, and no event which, after notice or lapse of time, or both, would become an Event of Default, shall have happened and be continuing, and (iii) certain other conditions are met.

EVENTS OF DEFAULT AND REMEDIES

An Event of Default with respect to the Debentures of any series is defined in the Indenture as being a:

(a) default in the payment of any interest upon any Debenture of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or

(b) default in the payment of the principal of or any premium on any Debenture of that series at its Maturity; or

(c) default in the performance, or breach, of any covenant or warranty of the Company in the Indenture (other than a covenant or warranty a default in the performance of which or the breach of which is elsewhere specifically dealt with or which has expressly been included in the Indenture solely for the benefit of series of Debentures other than that series), and continuance of such default or breach for a period of 90 days after there has been given written notice of such default to the Company by the Trustee or to the Company and the Trustee by the holders of at least 25% in principal amount of the outstanding Debentures of that series; or

(d) certain events of bankruptcy, insolvency or reorganization of the Company.

No Event of Default with respect to any particular series of Debentures necessarily constitutes an Event of Default with respect to any other series of Debentures. The Indenture provides that the Trustee thereunder may withhold notice to the holders of the Debentures of the occurrence of a default with respect to such Debentures (except a default in payment of principal, premium, if any, or interest) if the Trustee in good faith determines it is in the interest of the holders to do so.

The Indenture provides that if an Event of Default with respect to any Debentures of any series then outstanding issued thereunder shall occur and be continuing, either the Trustee or the holders of not less than 25% in aggregate principal amount of such Debentures then outstanding may declare the principal amount of all such Debentures of that series to be due and payable immediately, but upon certain conditions such declaration may be rescinded and annulled by the holders of a majority in aggregate principal amount of such Debentures then outstanding.

Subject to the provisions of the Trust Indenture Act of 1939, as amended, requiring each Trustee, during an Event of Default under the relevant Indenture, to act with the requisite standard of care, the Trustee is 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 any Debentures unless such holders have offered the Trustee reasonable indemnity. Subject to the foregoing, holders of a majority in aggregate principal amount of Debentures of any series then outstanding issued under the Indenture shall have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee under the Indenture with respect to such Debentures. The Indenture requires the annual filing by the Company with the Trustee of a certificate as to whether or not the Company is in default under the terms of the Indenture.

BOOK-ENTRY, DELIVERY AND FORM

Except as described below, each series of Debentures sold will be issued in the form of one or more Global Securities. The Global Securities will be deposited with, or on behalf of, the Depositary and registered in the name of the Depositary or its nominee. Except as set forth below, the Global Securities may be transferred, in whole and not in part, only to the Depositary or another nominee of the Depositary. Investors may hold their

beneficial interests in the Global Securities directly through the Depositary if they have an account with the Depositary or indirectly through organizations which have accounts with the Depositary.

Debentures (i) originally purchased by or transferred to institutional "accredited investors" who are not QIBS or (ii) except as described below, purchased by or transferred to Persons outside the United States pursuant to sales in accordance with Regulation S under the Securities Act (collectively referred to herein as the "Non-Global Purchasers"), will be in registered form without interest coupons ("Certificated Debentures"). Upon the transfer to a QIB of Certificated Debentures initially issued to a Non-Global Purchaser, such Certificated Debentures will be exchanged for an interest in the Global Security. For a description of the restrictions on transfer of Certificated Debentures, see "Notice to Investors."

Debentures originally purchased by persons outside the United States pursuant to sales in accordance with Regulation S under the Securities Act will be represented upon issuance by a temporary global Debenture certificate in fully registered form without interest coupons (the "Temporary Certificate") which will not be exchangeable for Certificated Debentures until the expiration of the "40-day restricted period" within the meaning of Rule 903(c)(3) of Regulation S under the Securities Act. The Temporary Certificate will be registered in the name of, and held by, a temporary certificate holder until the expiration of such 40-day period, at which time the Temporary Certificate will be delivered to the Trustee in exchange for Certificated Debentures registered in the names requested by such temporary certificate holder. In addition, until the expiration of such 40-day period, transfers of interests in the Temporary Certificate can only be effected through such temporary certificate holder in accordance with the requirements set forth in "Notice to Investors."

The Depositary has advised the Company as follows: The Depositary is a limited-purpose trust company and organized under the laws of the State of New York, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and "a clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary was created to hold securities of institutions that have accounts with the Depositary ("participants") and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The Depositary's participants include securities brokers and dealers (which may include the Initial Purchasers), banks, trust companies, clearing corporations and certain other organizations. Access to the Depositary's book-entry system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, whether directly or indirectly ("indirect participants").

Upon the issuance of the Global Securities, the Depositary or its custodian will credit, on its book-entry registration and transfer system, the principal amount of the Debentures represented by such Global Securities to the accounts of participants. The accounts to be credited shall be designated by the Initial Purchasers (as defined below) of such series of Debentures. Ownership of beneficial interests in the Global Securities will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in the Global Securities will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by the Depositary or its nominee (with respect to participants' interests) and such participants (with respect to the owners of beneficial interests in the Global Securities other than participants). The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to transfer or pledge beneficial interests in the Global Securities.

So long as the Depositary, or its nominee, is the registered holder and owner of the Global Securities, the Depositary or such nominee, as the case may be, will be considered the sole legal owner and holder of the related Debentures for all purposes of such Debentures and the Indenture. Except as set forth below, owners of beneficial interests in the Global Securities will not be entitled to have the Debentures represented by the Global Securities registered in their names, will not receive or be entitled to receive physical delivery of certificated Debentures in definitive form and will not be considered to be the owners or holders of any Debentures under the Global

43

Securities. The Company understands that under existing industry practice, in the event an owner of a beneficial interest in the Global Securities desires to take any action that the Depositary, as the holder of the Global Securities, is entitled to take, the Depositary would authorize the participants to take such action, and that the participants would authorize beneficial owners owning through such participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

Payment of principal of and interest on Debentures represented by the Global Securities registered in the name of and held by the Depositary or its nominee will be made to the Depositary or its nominee, as the case may be, as the registered owner and holder of the Global Securities.

The Company expects that the Depositary or its nominee, upon receipt of any payment of principal of or interest on the Global Securities, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Securities as shown on the records of the Depositary or its nominee. The Company also expects that payments by participants to owners of beneficial interests in the Global Securities held through such participants will be governed by standing instructions and customary practices and will be the responsibility of such participants. The Company will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the Global Securities for any Debentures or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between the Depositary and its participants or the relationship between such participants and the owners of beneficial interests in the Global Securities owning through such participants.

Unless and until exchanged in whole or in part for certificated Debentures in definitive form, the Global Securities for each series of Debentures may not be transferred except as a whole by the Depositary to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by the Depositary or any nominee to a successor of the Depositary or a nominee of such successor.

Although the Depositary has agreed to the foregoing procedures in order to facilitate transfers of interests in the Global Securities among participants of the Depositary, it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither the Trustee nor the Company will have any responsibility for the performance by the Depositary or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

The Global Securities representing the Debentures are exchangeable for definitive Debentures in registered form, of like tenor and of an equal aggregate principal amount, only if (x) the Depositary notifies the Company that it is unwilling, unable or ineligible to continue as Depositary for such Global Securities or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act, (y) the Company in its sole discretion determines that the Global Securities representing the Debentures shall be exchangeable for definitive Debentures in registered form or (z) any event shall have happened and be continuing which, after notice or lapse of time, or both, would become an Event of Default with respect to such Debentures. In the event that any Global Security representing the Debentures is exchangeable pursuant to the preceding sentence, it shall be exchangeable in whole for definitive Debentures in registered form, of like tenor and of an equal aggregate principal amount, in denominations of $1,000 and integral multiples thereof. Such definitive Debentures shall be registered in the name or names of such person or persons as the Depositary shall instruct the security registrar. It is expected that such instructions may be based upon directions received by the Depositary from its participants with respect to ownership of Debentures.

MODIFICATION OF THE INDENTURE

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the relevant series of Debentures, as the case may be, then outstanding and affected by a modification or amendment, to modify or amend any of the provisions of the Indenture or of such Debentures or the rights of the holders of such Debentures under the Indenture, provided

44

that no such modification or amendment shall, without the consent of each holder of each outstanding Debenture affected thereby:

(i) change the Stated Maturity of the principal of, or any installment of interest on, any such Debenture or reduce the principal amount thereof or any premium thereon, or reduce the rate of interest thereon, or change the coin or currency in which any Debenture or any premium or interest thereon is payable, or impair the holder's right to institute suit to enforce the payment of any such Debentures on or after the Stated Maturity,

(ii) reduce the aforesaid percentage in principal amount of such Debentures, the consent of the holders of which is required for any such modification or amendment or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Indenture or certain defaults thereunder and their consequences) or reduce the requirements for a quorum or voting at a meeting of holders of such Debentures,

(iii) change any obligation of the Company to maintain an office or agency in the places and for the purposes required by the Indenture, or

(iv) modify any of the above provisions.

The Indenture also contains provisions permitting the Company and the Trustee, without the consent of the holders of such Debentures issued thereunder, to modify or amend the Indenture in order, among other things:

(a) to add any additional Events of Default or add to the covenants of the Company for the benefit of the holders of all or any series of Debentures issued under the Indenture;

(b) to establish the form or terms of Debentures of any series;

(c) to cure any ambiguity, to correct or supplement any provision therein which may be inconsistent with any other provision therein, or to make any other provisions with respect to matters or questions arising under the Indenture which shall not adversely affect the interests of the holders of any debt securities issued thereunder in any material respect; or

(d) to change or eliminate any of the provisions of the Indenture, provided that any such change or elimination shall become effective only when there is no debt security outstanding of any series issued under the Indenture created prior to the execution of the supplemental indenture which is entitled to the benefit of such provision.

The holders of at least a majority in aggregate principal amount of outstanding Debentures of a series may, on behalf of the holders of Debentures of that series, waive compliance by the Company with certain restrictive provisions of the Indenture, including the covenant described above under "Certain Covenants of the Company--Limitation on Liens on Stock or Indebtedness of Principal Subsidiaries." The holders of not less than a majority in aggregate principal amount of such outstanding Debentures of any series may, on behalf of all holders of such series of Debentures, waive any past default under the Indenture with respect to such Debentures and its consequences, except a default in the payment of the principal of, premium, if any, or interest on such Debentures or in respect of a covenant or provision which cannot be modified or amended without the consent of the holder of each outstanding Debenture affected.

The Indenture contains provisions for convening meetings of the holders of the Debentures of any series. A meeting may be called at any time by the Trustee, and also, upon request, by the Company or the holders of at least 10% in aggregate principal amount of the outstanding Debentures of any series, in any such case upon notice given in accordance with the provisions of the Indenture. Except for any consent which must be given by the holder of each outstanding Debenture affected thereby, 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 such outstanding Debentures of that series; provided, however, that any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action which may be made, given or taken by the holders of a specified

45

percentage, which is less than a majority, in principal amount of such outstanding Debentures may be adopted at a meeting or adjourned meeting duly reconvened at which a quorum is present by the affirmative vote of the holders of such specified percentage in principal amount of such outstanding Debentures. Any resolution passed or decision taken at any meeting of holders of Debentures of any series duly held in accordance with the Indenture will be binding on all holders of such Debentures. 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 such outstanding Debentures, subject to certain exceptions.

SATISFACTION AND DISCHARGE OF THE INDENTURE; DEFEASANCE

The Indenture shall generally cease to be of any further effect if (a) the Company has delivered to the Trustee for cancellation all debt securities issued thereunder or (b) all debt securities issued thereunder not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year, and the Company shall have deposited with the Trustee as trust funds the entire amount sufficient to pay and discharge at Stated Maturity or upon redemption the entire indebtedness on all debt securities issued thereunder (and if, in either case, the Company has paid or caused to be paid all other sums payable under the Indenture by the Company and the Company has delivered an officers' certificate and an opinion of counsel each stating that the requisite conditions have been complied with).

In addition, the Company shall have a "legal defeasance option" (pursuant to which it may terminate, with respect to any series of Debentures, all of its obligations under such Debentures and the Indenture with respect to such Debentures) and a "covenant defeasance option" (pursuant to which it may terminate, with respect to any series of Debentures, its obligations with respect to such Debentures under certain specified covenants contained in the Indenture, including its obligations described under "Limitation on Liens on Stock and Indebtedness of Principal Subsidiaries"). If the Company exercises its legal defeasance option with respect to any series of Debentures, payment of such Debentures may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option with respect to any series of Debentures, payment of such Debentures may not be accelerated because of an Event of Default related to the specified covenants. The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.

The Company may exercise its legal defeasance option or its covenant defeasance option with respect to any series of Debentures, only if (a) the Company irrevocably deposits in trust with the Trustee cash and/or U.S. Government Obligations for the payment of principal, premium, if any, and interest with respect to such Debentures to maturity or redemption, as the case may be, and the Company delivers to the Trustee a certificate from a nationally recognized firm of independent public accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times and in such amounts as will be sufficient to pay the principal, premium, if any, and interest when due with respect to all such Debentures to maturity or redemption, as the case may be, (b) no Event of Default with respect to the Debentures of such series shall have occurred and be continuing (i) on the date of such deposit or (ii) with respect to certain bankruptcy defaults, at any time during the period ending on the 123rd day after the date of such deposit, (c) such legal defeasance or covenant defeasance does not result in the trust arising from such deposit to constitute, unless it is qualified as, a regulated investment company under the Investment Company Act of 1940, as amended, (d) the legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, the Indenture or any other agreement or instrument to which the Company is a party or by which it is bound, (e) the Company delivers to the Trustee an opinion of counsel that the holders of such Debentures will not recognize income, gain or loss for United States federal income tax purposes as a result of such legal defeasance or covenant defeasance and will be subject to United States federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance or covenant defeasance had not occurred, and (f) the Company delivers to the Trustee an officers' certificate and an opinion of counsel, each stating that all

46

conditions precedent to the defeasance and discharge of such Debentures as contemplated by the Indenture have been complied with. The opinion of counsel, with respect to legal defeasance, referred to in clause (e) 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 Indenture.

The Trustee shall hold in trust cash or U.S. Government Obligations deposited with it as described above and shall 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 such Debentures.

CONCERNING THE TRUSTEE

The Company has the right to replace the Trustee under certain circumstances, including (subject to the Company's satisfying certain conditions) if the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to another corporation or banking association.

The Company and certain of its subsidiaries may from time to time maintain lines of credit, and have other customary banking and commercial relationships, with the Trustee and its affiliates. The Trustee also acts as trustee under another indenture pursuant to which the Company issued its 9% Debentures Due 2006. The Trustee is the Administrative Agent under the Credit Agreement and is an affiliate of one of the Initial Purchasers, Chase Securities Inc. In addition, the Trustee and certain of its affiliates may own Debentures.

REGISTRATION RIGHTS AGREEMENT

The Company entered into the Registration Rights Agreement with the Initial Purchasers in connection with the sale of the Old Debentures pursuant to which the Company has agreed, for the benefit of the holders of each series of Old Debentures, at the Company's cost, to (i) file the Exchange Offer Registration Statement, of which this Prospectus is a part, within 150 days after the date of original issuance of such Old Debentures (May 8, 1997 for the Old 2032 Debentures and May 6, 1997 for the other Old Debentures, the "Issue Date") with the Commission with respect to the Exchange Offers and (ii) use its best efforts to cause the Exchange Offer Registration Statement to be declared effective under the Securities Act within 180 days after the Issue Date. Promptly after the Exchange Offer Registration Statement is declared effective, the Company will consummate the Exchange Offers. The Company will keep the Exchange Offers open for not less than 30 days (or longer if required by applicable law) after the date notice of the Exchange Offers is mailed to the holders of Old Debentures.

In the event that any changes in law or applicable interpretations of the staff of the Commission do not permit the Company to effect the Exchange Offers with respect to any series of Old Debentures, or if for any reason the Exchange Offer Registration Statement is not declared effective within 180 days following the Issue Date, or upon the request of the Initial Purchasers under certain circumstances, the Company will, in lieu of effecting the registration of the applicable New Debentures pursuant to the Exchange Offer Registration Statement and at its cost, (i) as promptly as practicable, file with the Commission a Shelf Registration Statement covering resales of the applicable Old Debentures, (ii) use its best efforts to cause the Shelf Registration Statement to be declared effective under the Securities Act by the 210th day after the Issue Date (or promptly in the event of a request by the Initial Purchasers) and (iii) keep effective the Shelf Registration Statement until the earliest of (x) the second anniversary of the Issue Date (or the first anniversary of the effective date if such Shelf Registration Statement is filed at the request of the Initial Purchasers), (y) the time when the Old Debentures registered thereunder can be sold by non-affiliates pursuant to Rule 144 under the Securities Act without limitation under clauses
(c), (e), (f) and (h) of Rule 144, or (z) such time as all the Old Debentures registered thereunder have been sold. During any consecutive 365-day period, the Company will have the ability to suspend the availability of the Shelf Registration Statement for up to two periods of up to 45 consecutive days, but no more than an aggregate of 60 days during any 365-day period. The Company will, in the event of the filing of a Shelf Registration Statement, provide to each holder of such applicable Old Debentures copies of the prospectus which is part of the Shelf Registration Statement, notify each such holder when the Shelf Registration Statement for such Old Debentures has become effective and take certain other actions as are required to permit unrestricted

47

resales of such Old Debentures. A holder of such Old Debentures that sells such Old Debentures pursuant to the Shelf Registration Statement generally will be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to the purchaser, will be subject to certain of the civil liability provisions under the Securities Act in connection with such sales and will be bound by the provisions of the Registration Rights Agreement which are applicable to such a holder (including certain indemnification obligations). In addition, each Holder of such Old Debentures will be required to deliver information to be used in connection with the Shelf Registration Statement and to provide comments on the Shelf Registration Statement within the time periods set forth in the Registration Rights Agreement in order to have their Old Debentures included in the Shelf Registration Statement and to benefit from the provisions regarding Special Interest set forth in the following paragraph. If the Company has consummated the Exchange Offers, then, subject to certain limited exceptions, the Company will have no obligation to file or to maintain the effectiveness of a Shelf Registration Statement with respect to any Old Debentures that are not tendered in the Exchange Offers.

In the event that (i) by the 150th day following the Issue Date, the Exchange Offer Registration Statement is not filed with the Commission, (ii) by the 180th day following the Issue Date, neither the Exchange Offer Registration Statement is declared effective nor (if the Exchange Offers are not permitted as described above) the Shelf Registration Statement is filed with the Commission, or (iii) by the 210th day following the Issue Date, one or more of the Exchange Offers with respect to any series of Old Debentures is not consummated or the Shelf Registration Statement is not declared effective with respect thereto (each such event referred to in clauses (i) through
(iii), a "Registration Default"), interest will accrue on the applicable Old Debentures (in addition to stated interest on such Old Debentures) from and including the next day following each such Registration Default. In each case such additional interest (the "Special Interest") will be payable in cash semiannually in arrears each May 1 and November 1, at a rate per annum equal to 0.25% of the principal amount of such Old Debentures for each such Registration Default. The aggregate amount of Special Interest payable pursuant to the above provisions will, however, in no event exceed 0.25% per annum of the principal amount of such Old Debentures. Upon (a) the filing of the Exchange Offer Registration Statement after the 150-day period described in clause (i) above, (b) the effectiveness of the Exchange Offer Registration Statement or the filing of the Shelf Registration Statement after the 180-day period described in clause (ii) above or (c) the consummation of the Exchange Offer for such Old Debentures or the effectiveness of a Shelf Registration Statement, as the case may be, after the 210-day period described in clause
(iii) above, the Special Interest payable on such Old Debentures as a result of the applicable Registration Default will cease to accrue. For purposes of the preceding sentence, the curing of a Registration Default by the means described in clause (b) above shall constitute a cure of the Registration Defaults described in clauses (i) and (ii) above, and the curing of a Registration Default by the means described in clause (c) above shall constitute a cure of the Registration Defaults described in clauses (i), (ii) and (iii) above.

In the event that a Shelf Registration Statement is declared effective pursuant to the paragraph preceding the immediately preceding paragraph, if the Company fails to keep such Registration Statement continuously effective for the period required by the Registration Rights Agreement (except as specifically permitted therein), then from such time as the Shelf Registration Statement is no longer effective until the earlier of (i) the date that the Shelf Registration Statement is again deemed effective and (ii) the date that is the earliest of (x) the second anniversary of the Issue Date (or until the first anniversary of the effective date if the Shelf Registration Statement is filed at the request of the Initial Purchasers), (y) the time when the Old Debentures registered thereunder can be sold by non-affiliates pursuant to Rule 144 under the Securities Act without any limitation under clauses (c),
(e), (f) and (h) of Rule 144, or (z) the date as of which all such Old Debentures are sold pursuant to the Shelf Registration Statement, Special Interest shall accrue at a rate per annum equal to 0.25% of the principal amount of the Old Debentures and shall be payable in cash semiannually in arrears each May 1 and November 1.

The summary herein of certain provisions of the Registration Rights Agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the Registration Rights Agreement, a copy of which is available upon request to the Company.

48

CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATION
IN THE EXCHANGE OFFERS

An exchange of the Old Debentures for the New Debentures pursuant to the Exchange Offers will not constitute a taxable event for federal income tax purposes. As a result, holders who exchange their Old Debentures for New Debentures should not recognize any income, gain or loss for federal income tax purposes with respect to such exchange. An exchanging holder will have the same adjusted basis and holding period in the New Debentures as it had in the Old Debentures immediately before the exchange.

HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF EXCHANGING OLD DEBENTURES FOR NEW DEBENTURES IN THE EXCHANGE OFFERS, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL, OR FOREIGN TAX LAWS.

PLAN OF DISTRIBUTION

Each broker-dealer that receives New Debentures for its own account pursuant to the Exchange Offers must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Debentures. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Debentures received in exchange for Old Debentures where such Old Debentures were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, starting on the Expiration Date and ending on the close of business 180 days after the Expiration Date, it will make this Prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

The Company will not receive any proceeds from any sale of New Debentures by broker-dealers. New Debentures received by broker-dealers for their own account pursuant to the Exchange Offers may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the New Debentures or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such New Debentures. Any broker-dealer that resells New Debentures that were received by it for its own account pursuant to the Exchange Offers and any broker or dealer that participates in a distribution of such New Debentures may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit of any such resale of New Debentures and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that by acknowledging that it will deliver and by delivering a prospectus meeting the requirements of the Securities Act, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

For a period of 180 days after the Expiration Date, the Company will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all expenses incident to the Exchange Offers (including the expenses of one counsel for the holders of the Old Debentures) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Old Debentures (including any broker dealers) against certain liabilities, including liabilities under the Securities Act.

VALIDITY OF DEBENTURES

The validity of the New Debentures offered hereby will be passed upon for the Company by McGuire, Woods, Battle & Boothe, L.L.P., Richmond, Virginia. Robert L. Burrus, Jr., a partner of McGuire, Woods, Battle & Boothe, L.L.P., is a director of the Company and owns 4,449 shares of the Company's common stock.

EXPERTS

The consolidated financial statements of the Company, incorporated by reference in this Prospectus and elsewhere in the Registration Statement, have been audited by Ernst & Young LLP, independent auditors, as set forth in their report thereon included therein and incorporated herein by reference. Such consolidated financial statements are incorporated by reference in this Prospectus and in the Registration Statement in reliance upon such report given upon the authority of said firm as experts in accounting and auditing.

The consolidated financial statements of Conrail as of December 31, 1996 and 1995, and for each of the years in the three-year period ended December 31, 1996 have been incorporated by reference in reliance on the report of Price Waterhouse LLP, independent accountants, given on the authority of said firm as experts in auditing and accounting.

With respect to the unaudited consolidated financial information of Conrail for the quarters ended March 31, 1997 and 1996, incorporated by reference in this Prospectus, Price Waterhouse LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report dated April 16, 1997 incorporated by reference herein, states that they did not audit and they do not express an opinion on that unaudited consolidated financial information. Price Waterhouse LLP has not carried out any significant or additional audit tests beyond those which would have been necessary if their report had not been included. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Price Waterhouse LLP is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited consolidated financial information because that report is not a "report" or a "part" of the registration statement prepared or certified by Price Waterhouse LLP within the meaning of Sections 7 and 11 of the Securities Act.

ITEM 20. 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 the Company's Amended and Restated Articles of Incorporation provides for mandatory indemnification of any director or officer of the Company who is, was or is threatened to be made a party to any proceeding (including any proceeding by or on behalf of the Company) by reason of the fact that he or she is or was a director or officer of the Company 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.

The Company'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 of officer of the Company to the Company or its shareholders arising out of a single transaction, occurrence or course of conduct shall be limited to one dollar.

The Company maintains a standard policy of officers' and directors' liability insurance.

Reference is made to the Purchase Agreement included herein as an exhibit to the Registration Statement for provisions regarding indemnification of the Company's officers, directors and controlling persons against certain liabilities.

ITEM 22. UNDERTAKINGS

The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any acts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement (notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act of 1933 if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement); (iii) to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in 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 Company 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 of 1933, 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.

The undersigned Registrant hereby further undertakes that, for the purpose of determining any liability under the Securities Act of 1933, 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.

II-2


Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant, pursuant to the provisions described under Item 15 or otherwise, the Registrant has 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 of 1933 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 Registrant 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 of 1933 and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the Prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request.

The undersigned Registrant hereby undertakes to supply by means of a post- effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective.

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS OR ANY OTHER APPLICABLE SECURITIES LAW. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION.

Re: CSX Corporation (the "Company")
___% Securities due May 1, 20__ (the "Securities")

Ladies and Gentlemen:

1. We understand that the _____% Securities due May 1, ____, (the "Offered Securities") of CSX Corporation (the "Company") have not been registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws, and may not be offered or sold except as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing the Offered Securities that, if, prior to the date which is two years after the later of the date of original issue of the Offered Securities and the last date on which the Company or any affiliate of the Company was the owner of such Offered Securities (the "Resale Restriction Termination Date"), we decide to offer, sell or otherwise transfer any such Offered Securities, such offer, sale or transfer will be made only (a) to the Company, (b) pursuant to an effective registration statement under the Securities Act, (c) so long as the Offered Securities are eligible for resale pursuant to Rule 144A under the Securities Act, to a person we reasonably believe is a qualified institutional buyer under Rule 144A (a "QIB") that purchases for its own account or for the account of a QIB and to whom notice is given that the transfer is being made in reliance on Rule 144A, (d) to an institutional "accredited investor" within the meaning of subparagraph (a)(1),
(2), (3) or (7) of Rule 501 under the Securities Act that is acquiring Offered Securities for its own account or for the account of such an institutional accredited investor for investment purposes and not with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act, (e) pursuant to offers and sales to non-U.S. persons that occur outside the United States within the meaning of Regulation S under the Securities Act or (f) pursuant to another available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirements of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control and to compliance with any applicable state securities laws. The foregoing restrictions on resale will


16

not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer of the Offered Securities is proposed to be made pursuant to clause (d) above prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form of this letter to the Trustee, which shall provide as applicable, among other things, that the transferee is an institutional "accredited investor" within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act that is acquiring such Offered Securities for investment purposes and not for distribution in violation of the Securities Act. We acknowledge on our behalf and on behalf of any investor account for which we are purchasing Offered Securities that the Company and the Trustee reserve the right prior to any offer, sale or other transfer pursuant to clause (d), (e) or (f) prior to the Resale Restriction Termination Date of the Offered Securities to require the delivery of any opinion of counsel, certifications and/or other information satisfactory to the Company and the Trustee. We understand that the certificates for any Offered Security that we receive will bear a legend substantially to the effect of the foregoing.

2. We are an institutional "accredited investor" within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities Act purchasing for our own account or for the account of such an institutional "accredited investor," and we are acquiring the Offered Securities for investment purposes and not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act and we have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Offered Securities, and we and any account for which we are acting are each able to bear the economic risks of our or its investment.

3. We are acquiring the Offered Securities purchased by us for our own account (or for one or more accounts as to each of which we exercise sole investment discretion and have authority to make, and do make, the statements contained in this letter) and not with a view to any distribution of the Offered Securities, subject, nevertheless, to the understanding that the disposition of our property will at all times be and remain within our control.

4. We acknowledge that (a) none of the Company, or the Initial Purchasers (as defined in the Offering Memorandum dated May 1, 1997 relating to the Offered Securities (the "Final Memorandum")) nor any person acting on behalf of the Company or the Initial Purchasers has made any representation to us with respect to the Company or the offer or sale of any Offered Securities and (b) any information we desire concerning the Company and the Offered Securities or any other matter relevant to our decision to purchase the Offered Securities (including a copy of the Final Memorandum) is or has been made available to us.

5. We acknowledge that the Company, the Trustee, Initial Purchasers and others will rely upon the truth and accuracy of the foregoing acknowledgements, representations,


17

warranties and agreements and agree that if any of the acknowledgements, representations, warranties and agreements made by us herein with respect to our purchase of the Offered Securities are no longer accurate, we shall promptly notify the Initial Purchasers.

Section 1.11 Redemption of Securities. Section 1102 of the Indenture is hereby amended and supplemented to read as follows:

Section 1102. Election to Redeem; Notice to Trustee.

The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In the case of any redemption at the election of the Company, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company, notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed.

Section 1.12 Repayment at the Option of Holders. The Indenture is amended and supplemented by adding the following Article Fifteen:

ARTICLE FIFTEEN

REPAYMENT AT THE OPTION OF HOLDERS

Section 1501. Applicability of Article. Repayment of Securities of any series before their Stated Maturity at the option of Holders thereof shall be made in accordance with the terms of such Securities and (except as otherwise specified by the terms of such series established pursuant to Section 301) in accordance with this Article.

Section 1502. Repayment of Securities. Securities of any series subject to repayment in whole or in part at the option of the Holders thereof will, unless otherwise provided in the terms of such Securities, be repaid at a price equal to the principal amount thereof, together with interest, if any, thereon accrued to the Repayment Date specified in or pursuant to the terms of such Securities. The Company covenants that on or before the Repayment Date it will deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money sufficient to pay the principal (or, if so provided by the terms of the Securities of any series, a percentage of the principal) of, and (except if the Repayment Date shall be an Interest Payment Date) accrued interest on, all the Securities or portions thereof, as the case may be, to be repaid on such date.

Section 1503. Exercise of Option. Securities of any series subject to repayment at the option of the Holders thereof will contain an "Option of Holder to Elect Purchase" form on such Securities. In order for any Security to be repaid at the option of the Holder, the Trustee must receive at the Place to Payment therefor specified in the terms of such Security (or at such other place or places of which the Company shall from time to time notify the Holders of such Securities) not earlier than 60 days nor later than 30 days prior to the Repayment Date (1) the Security so providing for such repayment together with the "Option of Holder to Elect Purchase" form duly completed by the Holder (or by the Holder's

20

attorney duly authorized in writing) or (2) a telegram, facsimile transmission or a letter from a member of a national securities exchange, or the National Association of Securities Dealers, Inc. ("NASD"), or a commercial bank or trust company in the United States setting forth the name of the Holder of Security, the principal amount of the Security, the amount of the Security to be repaid, the certificate number or a description of the tenor and terms of the Security, a statement that the option to elect repayment is being exercised thereby and a guarantee that the Security to be repaid, together with the duly completed form entitled "Option of Holder to Elect Purchase", will be received by the Trustee not later than the fifth Business Day after the date of such telegram, facsimile transmission or letter; provided, however, that such telegram, facsimile transmission or letter shall only be effective if such Security and form duly completed are received by the Trustee by such fifth Business Day. If less than the entire principal amount of such Security is to be repaid in accordance with the terms of such Security, the principal amount of such Security to be repaid, in increments of the minimum denomination for Securities of such series, and the denomination or denominations of the Security or Securities to be issued to the Holder for the portion of the principal amount of such Security surrendered that is not to be repaid, must be specified. The principal amount of any Security providing for repayment at the option of the Holder thereof may not be repaid in part if, following such repayment, the unpaid principal amount of such Security would be less than the minimum authorized denomination of Securities of the series of which such Security to be repaid is a part. Except as otherwise may be provided by the terms of any Security providing for repayment at the option of the Holder thereof, exercise of the repayment option by the Holder shall be irrevocable unless waived by the Company.

Section 1504. When Securities Presented for Repayment Become Due and Payable. If the Securities of any series providing for repayment at the option of the Holders thereof shall have been surrendered as provided in this Article and as provided by or pursuant to the terms of such Securities, such Securities or the portions thereof, as the case may be, to be repaid shall become due and payable and shall be paid by the Company on the Repayment Date therein specified, and on and after such Repayment Date (unless the Company shall default in the payment of such Securities on such Repayment Date) such Securities so to be repaid shall cease to bear interest. Upon surrender of any such Security for repayment in accordance with such provisions, the principal amount of such Security so to be repaid shall be paid by the Company, together with accrued interest, if any, to the Repayment Date; provided that, installments of interest, if any, whose Stated Maturity is on or prior to the Repayment Date shall be payable (but without interest thereon, unless the Company shall default in the payment thereof) to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307.

If the principal amount of any Security surrendered for repayment shall not be so repaid upon surrender thereof, such principal amount (together with interest, if any,


21

thereon accrued to such Repayment Date) shall, until paid, bear interest from the Repayment Date at the rate of interest set forth in such Security.

Section 1505. Securities Repaid in Part. Upon surrender of any Registered Security which is to be repaid in part only, the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge and at the expense of the Company, a new Registered Security or Securities of the same series, of any authorized denomination specified by the Holder, in an aggregate principal amount equal to and in exchange for the portion of the principal of such Security so surrendered which is not to be repaid.

Section 1506. Compliance with Exchange Act. In connection with any Repayment of Securities pursuant to this Article, the Company will comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Securities Exchange Act of 1934, if required, and will file Schedule 13E-4 or any other schedule, if required.

[ISIN] [____________]

This security (the "Security") is one of a duly authorized issue of securities (herein called the "Securities") of CSX Corporation, a Virginia corporation (hereinafter called the "Company," which term includes any successor corporation under the Indenture hereinafter referred to), issued and to be issued in one or more series under an indenture, unlimited as to aggregate principal amount, dated as of August 1, 1990 between the Company and The Chase Manhattan Bank, Trustee (herein called the "Trustee," which term includes any successor trustee under the Indenture (as hereinafter defined)), as supplemented by a First Supplemental Indenture dated as of June 15, 1991 and a Second Supplemental Indenture dated as of May 6, 1997, to which indenture and all indentures supplemental thereto (the indenture, as supplemented being herein called the "Indenture") reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, which series has been issued in an aggregate initial principal amount of $_____________ ([DOLLARS]). This Security represents an aggregate initial principal amount of $________________ ([DOLLARS]) (as adjusted from time to time in accordance with the terms and provisions hereof and as set forth on Exhibit A hereto, the "Principal Amount") of the Securities of such series, with the Interest Payment Dates, date of original issuance, and date of Maturity specified herein and bearing interest on said Principal Amount at the interest rate specified herein.

The Company, for value received, hereby promises to pay to _______________ or its registered assigns, the principal sum of $____________ ([DOLLARS]) on May 1, 20__, and to pay interest (computed on the basis of a 360- day year of twelve 30-day months) thereon from the Issue Date or from the most recent Interest Payment Date to which interest has been paid or duly provided for, or, if the date of this Security is an Interest Payment Date to which interest has been paid or duly provided for, then from the date hereof, semiannually in arrears on May 1 and November 1 in each year,


4

commencing November 1, 1997, and at Maturity at the rate of ___% per annum, until the principal hereof is paid or duly made available for payment. The Company shall pay interest on overdue principal and premium, if any, and (to the extent lawful) interest on overdue installments of interest at the rate per annum borne by the Security. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the April 15 or October 15 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Except as otherwise provided in the Indenture, any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date to be fixed by the Trustee for the payment of such Defaulted Interest, notice whereof shall be given to the Holder of this Security not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Security of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in such Indenture. Notwithstanding the foregoing, interest payable on this Security at Maturity will be payable to the person to whom principal is payable.

[Additional Interest (the "Special Interest") shall become payable in respect of the Security as follows, if any of the following events occur with respect to such Security (each such event in clauses (i) through (iv) below, a "Registration Default"):

(i) if a registration statement for an exchange offer (the "Exchange Offer") under the Securities Act with respect to the Securities (an "Exchange Offer Registration Statement") is not filed with the Commission on or prior to 150 days after the Issue Date;

(ii) if neither the Exchange Offer Registration Statement is declared effective nor (if the Exchange Offer is not permitted for the reasons described in the Registration Rights Agreement dated as of May 6, 1997 among the Company and the Initial Purchasers (the "Registration Rights Agreement")) a shelf registration statement under the Securities Act with respect to the Securities (the "Shelf Registration Statement") is filed with the Commission on or prior to 180 Days after the Issue Date;

(iii) if one or more of the Exchange Offers is not consummated with respect to the Securities of this series or the Shelf Registration Statement is declared effective on or prior to 210 days after the Issue Date; or

(iv) if, after 210 days after the Issue Date, and after the Shelf Registration Statement is declared effective, the Company fails to keep the Shelf Registration Statement effective (except as permitted by the proviso to
Section 3(b) of the Registration Rights


5

Agreement) then from such time as the Shelf Registration Statement is no longer effective until the earlier of (i) the date that the Shelf Registration Statement is again deemed effective and (ii) the date that is the earliest of
(x) the second anniversary of the Issue Date (or until the first anniversary of the effective date of the Shelf Registration Statement if the Shelf Registration Statement is filed at the request of the Initial Purchaser), (y) the time when the Security registered under the Shelf Registration Statement can be sold by non-Affiliates pursuant to Rule 144 under the Act without any limitations under clauses (c), (e), (f) and (h) of Rule 144, or (z) the date as of which all of such Securities are sold pursuant to the Shelf Registration Statement.

The holder of this Security is entitled to the benefits of the Registration Rights Agreement.

Special Interest shall accrue on the Security, over and above the interest rate set forth in the Indenture applicable to such Security following the occurrence of each Registration Default set forth in clauses (i), (ii),
(iii) and (iv) above from and including the next day following each such Registration Default, in each case at a rate equal to 0.25% per annum of the principal amount of such Security, provided, however, that the aggregate amount of Special Interest payable will in no event exceed 0.25% per annum of the principal amount of the Security. The Special Interest attributable to each Registration Default shall cease to accrue from the date such Registration Default is cured. Upon (a) the filing of the Exchange Offer Registration Statement after the period described in clause (i) above, (b) the effectiveness of the Exchange Offer Registration Statement or the filing of the Shelf Registration Statement after the period described in clause (ii) above or (c) the consummation of the Exchange Offer for such Security or the effectiveness of a Shelf Registration Statement, as the case may be, after the period described in clause (iii) above, Special Interest payable on such Security as a result of the applicable Registration Default will cease to accrue. For purposes of the preceding sentence, the curing of a Registration Default by the means described in clause (b) above shall constitute a cure of the Registration Defaults described in clauses (i) and (ii) above, and the curing of a Registration Default by the means described in clause (c) above shall constitute a cure of the Registration Defaults described in clauses (i), (ii) and (iii) above.

Any amounts of Special Interest due pursuant to the foregoing paragraphs will be payable in cash on May 1 and November 1 of each year to the holders of record on the preceding April 15 and October 15, respectively.]*

This Security is exchangeable in whole or from time to time in part for definitive Registered Securities of this series only as provided in this paragraph. If (x) the U.S. Depository with respect to the Securities of this series (the "U.S. Depository") notifies


* Only for a Security not registered under the Securities Act.

the Company that it is unwilling, unable or ineligible to continue as U.S. Depository for this Security or if at any time the U.S. Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, (y) the Company in its sole discretion determines that this Security shall be exchangeable for definitive Registered Securities and executes and delivers to the Trustee a Company Order providing that this Security shall be so exchangeable or (z) there shall have happened and be continuing an Event of Default or any event which, after notice or lapse of time, or both, would become an Event of Default with respect to the Securities of the series of which this Security is a part, this Security or any portion hereof shall, in the case of clause (x) above, be exchanged for definitive Registered Securities of this series, and in the case of clauses (y) and (z) above, be exchangeable for definitive Registered Securities of this series, provided that the definitive Security so issued in exchange for this Security shall be in authorized denominations and be of like tenor and of an equal aggregate principal amount as the portion of the Security to be exchanged, and provided further that, in the case of clauses (y) and (z) above, definitive Registered Securities of this series will be issued in exchange for this Security, or any portion hereof, only if such definitive Registered Securities were requested by written notice to the Security Registrar by or on behalf of a Person who is a beneficial owner of an interest herein given through the Holder hereof. Any definitive Registered Security of this series issued in exchange for this Security, or any portion hereof, shall be registered in the name or names of such Person or Persons as the Holder hereof shall instruct the Security Registrar. Except as provided above, owners of beneficial interests in this Security will not be entitled to receive physical delivery of Security in definitive form and will not be considered the Holders thereof for any purpose under the Indenture.

Any exchange of this Security or portion hereof for one or more definitive Registered Securities of this series will be made at the New York office of the Security Registrar. Upon exchange of any portion of this Security for one or more definitive Registered Securities of this series, the Trustee shall endorse Exhibit A of this Security to reflect the reduction of its Principal Amount by an amount equal to the aggregate principal amount of the definitive Registered Securities of this series so issued in exchange, whereupon the Principal Amount hereof shall be reduced for all purposes by the amount so exchanged and noted. Except as otherwise provided herein or in the Indenture, until exchanged in full for one or more definitive Registered Securities of this series, this Security shall in all respects be subject to and entitled to the same benefits and conditions under the Indenture as a duly authenticated and delivered definitive Registered Security of this series.

The principal and any interest in respect of any portion of this Security payable in respect of an Interest Payment Date or at the Stated Maturity thereof, in each case occurring prior to the exchange of such portion for a definitive Registered Security or Securities of this series, will be paid, as provided herein, to the Holder hereof which will undertake in such circumstances to credit any such principal and interest received by it in respect of this Security to the respective accounts of the Persons who are the beneficial owners of such interests on such Interest Payment Date or at Stated Maturity. If a definitive


7

Registered Security or Registered Securities of this series are issued in exchange for any portion of this Security after the close of business at the office or agency where such exchange occurs on (i) any Regular Record Date and before the opening of business at such office or agency on the relevant Interest Payment Date, or (ii) any Special Record Date and before the opening of business at such office or agency on the related proposed date for payment of Defaulted Interest, then interest or Defaulted Interest, as the case may be, will not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Registered Security, but will be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Holder hereof, and the Holder hereof will undertake in such circumstances to credit such interest to the account or accounts of the Persons who were the beneficial owners of such portion of this Security on such Regular Record Date or Special Record Date, as the case may be.

Payment of the principal of and any such interest on this Security will be made at the offices of The Chase Manhattan Bank, as Paying Agent, in the Borough of Manhattan, The City of New York, or at such other office or agency of the Company as may be designated by it for such purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts by check mailed to the registered Holders thereof; provided, however, that at the option of the Holder, payment of interest may be made by wire transfer of immediately funds to an account of the Person entitled hereto as such account shall be provided to the Security Registrar and shall appear in the Security Register.

[The Company may be required to repurchase the Securities of this series, in whole or in part (the "Put Option"), on May 1, 20__, (the "Put Option Exercise Date") at a purchase price equal to 100% of the principal amount tendered by the Holder, plus accrued interest, if any, to the Put Option Exercise Date. On or before the Put Option Exercise Date, the Company shall deposit with the Trustee money sufficient to pay the principal of and any interest accrued on the such Securities to be tendered for repayment. On and after the Put Option Exercise Date, interest will cease to accrue on such Securities or any portion thereof tendered for repayment.

In the event of repurchase of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

A holder must provide the Company with notice of its intention to exercise the Put Option during the period from and including March 1, 20__ through and including April 1, 20__. Such notice, once given, will be irrevocable unless waived by the Company.]

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding on behalf of the Holders of all Securities of such series to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and the Persons who are beneficial owners of interests represented hereby, and of any Security issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Security.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the Outstanding Securities of this series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of (and premium, if any) or interest on this Security on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional to pay the principal of (and premium, if any) and interest on this Security at the time, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of Registered Securities of the series of which this Security is a part may be registered on the Security Register of the Company, upon surrender of such Securities for registration of transfer at the office of the Security Registrar, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or his attorney duly authorized in

The sale of the Securities to the Initial Purchasers will be made without registration of the Securities under the Securities Act of 1933, as amended (the "Securities Act"), in reliance upon exemptions from the registration requirements of the Securities Act. You have advised the Company that the Initial Purchasers will offer and sell the Securities purchased by them hereunder in accordance with Section 4 hereof as soon as you deem advisable.

Holders of the Securities will be entitled to the benefits of the Registration Rights Agreement (the "Registration Rights Agreement"), to be dated the First Closing Date (as defined below), in each case among the Company and the Initial Purchasers. The Registration Rights Agreement will be as described in the Preliminary Offering Memorandum (as defined below), with such changed, other or additional terms reasonably acceptable to the Company and the Initial Purchasers.

In connection with the sale of the Securities, the Company has prepared a preliminary offering memorandum, dated April 22, 1997 (including any and all exhibits thereto and any information incorporated by reference therein, the "Preliminary Memorandum") and a final offering memorandum, dated May 1, 1997 (including any and all exhibits thereto and any information incorporated by reference therein, the "Final Memorandum"). Each of the Preliminary Memorandum and the Final Memorandum sets forth certain information concerning the Company and the Securities. The Company hereby confirms that it has authorized the use of the Preliminary Memorandum and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers. Unless stated to the contrary, all references herein to the Final Memorandum are to the Final Memorandum at the Execution Time (as defined below) and are not meant to include any amendment or supplement, or any information incorporated by reference therein, subsequent to the Execution Time, and any reference to the terms "amend," "amendment" or "supplement" with respect to the Final Memorandum shall be deemed to refer to and include any information filed under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), subsequent to the Execution Time which is incorporated by reference therein.

2

the Company makes no representation or warranty as to the information contained in or omitted from the Final Memorandum, or any amendment or supplement thereto, in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of the Initial Purchasers through the Representative specifically for inclusion therein. All documents incorporated by reference in the Final Memorandum which were filed under the Exchange Act on or before the Execution Time complied, and all such documents which are filed under the Exchange Act after the Execution Time and on or before the applicable Closing Date will comply, in all material respects with the applicable requirements of the Exchange Act and the rules thereunder.

(b) The Company has not taken and will not take, directly or indirectly, any action designed to or which has constituted or which might reasonably be expected to cause or result in stabilization or manipulation of the price of the Securities (other than any stabilization done by the Initial Purchasers, as to which the Company makes no representation).

5

5. Agreements. The Company agrees with each Initial Purchaser that:

(a) The Company will furnish to each Initial Purchaser and to Counsel for the Initial Purchasers, without charge, during the period referred to in paragraph (c) below, as many copies of the Final Memorandum and any amendments and supplements thereto as it may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering.

(b) The Company will not amend or supplement the Final Memorandum (other than by filing documents under the Exchange Act which are incorporated by reference therein), without having previously advised and furnished to the Representative a copy of such amendment or supplement to which the Representative, on advice from counsel, has not reasonably objected; provided, however, that, prior to the completion of the distribution of the Securities by the Initial Purchasers (as determined by the Representative), the Company will not file any document under the Exchange Act which is incorporated by reference in the Final Memorandum unless, prior to such proposed filing, the Company has furnished the Representative with a copy of such document. The Company will promptly advise the Representative when any document filed under the Exchange Act which is incorporated by reference in the Final Memorandum shall have been filed with the Securities and Exchange Commission (the "Commission").

Section 5, will prepare and provide to the Representative pursuant to paragraph (a) of this Section 5 an amendment or supplement which will correct such statement or omission or effect such compliance and, in the event that such an amendment or supplement is required to be filed under the Exchange Act and is to be incorporated by reference in the Final Memorandum, will file such amendment or supplement with the Commission. The Representative will promptly

6

advise the Company, in writing, of the completion of the initial distribution of the Securities.

(d) The Company will cooperate with the Initial Purchasers and their counsel in arranging for the qualification of the Securities for sale by the Initial Purchasers under the laws of such jurisdictions as the Initial Purchasers may designate and will maintain such qualifications in effect so long as required for the sale of the Securities; provided, however, that in connection therewith, the Company shall not be required to qualify as a foreign corporation or to execute a general consent to service of process in any jurisdiction or subject itself to taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject. The Company will promptly advise the Representative of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(e) The Company will not, and will not permit any of its Affiliates to, resell any Securities that have been acquired by any of them.

(f) Neither the Company, nor any of its Affiliates, nor any person acting on its or their behalf will, directly or indirectly, make offers or sales of any security, or solicit offers to buy any security, which are or could be integrated with the sale of the Securities in a manner that would require the registration of the Securities under the Securities Act.

(g) Neither the Company, nor any person acting on its behalf, will engage in any form of general solicitation or general advertising (within the meaning of Rule 502(c) of Regulation D) in connection with any offer or sale of the Securities in the United States, except as contemplated by the Registration Rights Agreement.

(h) So long as any of the Securities are "restricted securities" within the meaning of Rule 144(a)(3) under the Securities Act, the Company will, during any period in which it is not subject to Section 13 or 15(d) of the Exchange Act, provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Securities Act.

(i) The Company shall, during any period in the two years after the Closing Date in which the Company is subject to the reporting requirements of Section 13 or Section 15(d) of the Exchange Act, timely file all Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and any other reports, statements, documents, registrations, filings or submissions required to be filed by the Company with the Commission pursuant to the Exchange Act.

7

(j) Neither the Company, nor any of its Affiliates, nor any person acting on its or their behalf will engage in any directed selling efforts with respect to the Securities, and each of them will comply with the offering restrictions requirement of Regulation S. Terms used in this paragraph have the meanings given to them by Rule 902(b) of Regulation S.

(k) The Company will cooperate with the Representative and use its reasonable best efforts to permit the Securities to be eligible for clearance and settlement through The Depository Trust Company.

(l) If requested by the Initial Purchasers, the Company shall use its reasonable best efforts to cause Securities sold in reliance on Rule 144A to be eligible for the PORTAL trading system of the National Association of Securities Dealers, Inc.

(m) Until such time as any Security is registered under the Securities Act pursuant to the Registration Rights Agreement and transferred pursuant to such registration, the Company shall include a legend on the Securities to the effect as set forth under "Notice to Investors" in the Final Memorandum.

6. Conditions to the Obligations of the Initial Purchasers. The obligations of the Initial Purchasers to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein at the date and time that this Agreement is executed and delivered by the parties hereto (the "Execution Time"), and, with respect to the 2002 Debentures, the 2004 Debentures, the 2007 Debentures, the 2017 Debentures, the 7.95% 2027 Debentures, the 6.95% 2027 Debentures and the 7.25% 2027 Debentures, the First Closing Date and, with respect to the 2032 Debentures, the Second Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a) The Company shall have furnished to the Initial Purchasers the opinion of the General Counsel, or an Assistant General Counsel, of the Company, dated the applicable Closing Date, to the effect that:

(i) The Company has been duly incorporated and is an existing corporation in good standing under the laws of the Commonwealth of Virginia, with corporate power and authority to own, lease and operate its properties and conduct its business as described in the Final Memorandum; and the Company is duly qualified to do business as a foreign corporation in good standing in all other jurisdictions in which it owns or leases substantial properties or in which the conduct of its business requires such qualification except where the failure to so qualify or be in good standing would not have a

8

material adverse effect on the Company and its subsidiaries, considered as one enterprise;

(ii) Each significant subsidiary as defined in Rule 405 of Regulation C of the Securities Act (each a "Significant Subsidiary") of the Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has corporate power and authority to own, lease and operate its properties and conduct its business as described in the Final Memorandum; and, to the best of such counsel's knowledge, is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, except where the failure to so qualify or be in good standing would not have a material adverse effect on the Company and its subsidiaries, considered as one enterprise; all of the issued and outstanding capital stock of each Significant Subsidiary has been duly authorized and validly issued, is fully paid and nonassessable, and, except for directors' qualifying shares, if any, is owned by the Company free and clear of any mortgage, pledge, lien, encumbrance, claim or equity;

(iii) No consent, approval, authorization or order of, or filing with, any governmental agency or body or any court is required for the consummation of the transactions contemplated herein, except such as may be required under state securities laws; and

(iv) The execution, delivery and performance of the Indenture, this Agreement, the Registration Rights Agreement and the issuance and sale of the Securities and compliance with the terms and provisions thereof will not result in a material breach or violation of any of the terms and provisions of, or constitute a default under, any statute, rule, regulation or order of any governmental agency or body or any court having jurisdiction over the Company or any Significant Subsidiary or any of their properties or, to the best of such counsel's knowledge, any agreement or instrument to which the Company or any of its Significant Subsidiaries is a party or by which the Company or any Significant Subsidiary is bound or to which any of the properties of the Company or any Significant Subsidiary is subject, or the charter or by-laws of the Company or any Significant Subsidiary, and the Company has full power and authority to authorize, issue and sell the Securities as contemplated by this Agreement.

In addition, such counsel shall state that he or she has participated in conferences with officers and other representatives of the Company, representatives of Ernst & Young, independent auditors for the Company, and the Representative, at which the contents of the Final Memorandum and any amendment thereof or supplement thereto and related matters were discussed and although such counsel has

9

not undertaken to investigate or verify independently, and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Final Memorandum or any amendment thereof or supplement thereto, no facts have come to the attention of such counsel which would lead such counsel to believe that at the Execution Time the Final Memorandum (other than the historical, proforma, projected or other financial statements, information and data and statistical information and data included or incorporated by reference therein, in each case as to which no opinion need be given) contained any untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or that the Final Memorandum (other than the historical, proforma, projected or other financial statements, information and data and statistical information and data included or incorporated by reference therein, in each case as to which no opinion need be given) at the applicable Closing Date includes any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Except as otherwise set forth herein, all references in this Section 6(a) to the Final Memorandum shall be deemed to include any amendment or supplement thereto at the applicable Closing Date.

(b) The Company shall have furnished to the Initial Purchasers the opinion of McGuire, Woods, Battle & Boothe, L.L.P., counsel for the Company, dated the applicable Closing Date, to the effect that:

(i) The Indenture has been duly authorized, executed and delivered by the Company; the Securities have been duly authorized, executed, issued and delivered by the Company; the Indenture and the Securities, when authenticated in the manner provided in the Indenture, constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles (in rendering such opinion, such counsel may assume that the Indenture has been duly authorized, executed and delivered, and the Securities have been duly authenticated, by the Trustee); and the Securities conform to the description thereof contained in the Final Memorandum;

(ii) The Registration Rights Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles (in rendering such opinion, such counsel may assume due authorization, execution

10

and delivery by parties thereto other than the Company), provided, however, that no opinion is rendered as to the enforceability against the Company of any rights to indemnification or contribution included therein; and the Registration Rights Agreement conforms to the description thereof contained in the Final Memorandum;

(iii) This Agreement has been duly authorized, executed and delivered by the Company;

(iv) Assuming the accuracy of the representations and warranties and compliance with the agreements made by the Company and the Initial Purchasers herein, it is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers under, or in connection with the initial resale of such Securities by the Initial Purchasers in the manner contemplated by, this Agreement to register the Securities under the Securities Act or to qualify the Indenture, as amended, under the Trust Indenture Act of 1939, as amended;

(vi) The Company is not an "investment company" within the meaning of the Investment Company Act without taking account of any exemption arising out of the number of holders of the Company's securities;

(vii) The statements in the Final Memorandum under the captions "Description of Debentures" and "Exchange Offers; Registration Rights", insofar as they purport to summarize certain provisions of the Securities and the Registration Rights Agreement, are accurate summaries of such provisions; and

(viii) The information contained in the Final Memorandum under the caption "Certain Federal Income Tax Considerations for Non-U.S. Holders", to the extent that it constitutes matters of law or legal conclusions, has been reviewed by such counsel and is correct in all material respects.

In addition, subject to such counsel's customary qualifications about the scope of its obligations in connection with its participation in the preparation of documents, such counsel shall state that they have participated in conferences with officers and other representatives of the Company, representatives of Ernst & Young, independent auditors for the Company, the Representative, and Counsel for the Initial Purchasers at which the contents of the Final Memorandum and any amendment thereof or supplement thereto and related matters were discussed and although such counsel have not undertaken to investigate or verify independently, and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Final Memorandum or any amendment thereof or supplement thereto, and did not participate in the preparation of the documents incorporated by reference in the Final

11

Memorandum, no facts have come to the attention of such counsel which would lead such counsel to believe that at the Execution Time the Final Memorandum (other than the historical, proforma, projected or other financial statements, information and data and statistical information and data included or incorporated by reference therein, in each case as to which no opinion need be given) contained any untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or that the Final Memorandum at the applicable Closing Date (other than the historical, proforma, projected or other financial statements, information and data and statistical information and data included or incorporated by reference therein, in each case as to which no opinion need be given) includes any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

In rendering such opinion, McGuire, Woods, Battle & Boothe, L.L.P. may rely (A) as to matters governed by New York law upon the opinion of Counsel for the Initial Purchasers, referred to below and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. Except as otherwise set forth herein, all references in this Section 6(b) to the Final Memorandum shall be deemed to include any amendment or supplement thereto at the applicable Closing Date.

(c) The Representative shall have received from Counsel for the Initial Purchasers such opinion or opinions, dated the Closing Date, with respect to the issuance and sale of the Securities, the Final Memorandum (as amended or supplemented at the applicable Closing Date) and other related matters as they may require, and the Company shall have furnished to such counsel such documents as they may reasonably request for the purpose of enabling them to pass upon such matters. In rendering such opinion, Counsel for the Initial Purchasers may rely as to the incorporation of the Company on the opinion of the General Counsel or Assistant General Counsel of the Company and as to all other matters governed by Virginia law upon the opinion of McGuire, Woods, Battle & Boothe, L.L.P., referred to above.

(d) The Company shall have furnished to the Representative a certificate of the Company, signed by the Chairman of the Board or the President or an Executive Vice President or the Managing Director-Corporate Finance and another person who is the principal financial or accounting officer of the Company, dated the applicable Closing Date, to the effect that the signers of such certificate have examined the Final Memorandum, any amendment or supplement to the Final Memorandum and this Agreement and that, to the best of their knowledge after reasonable investigation:

(i) the representations and warranties of the Company in this Agreement are true and correct in all material respects on and as of the

12

applicable Closing Date with the same effect as if made on and as of such Closing Date, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to such Closing Date; and

(ii) since the date of the most recent financial statements incorporated by reference in the Final Memorandum, there has been no material adverse change in the condition (financial or other), earnings, business or properties of the Company and its subsidiaries, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated by the Final Memorandum (exclusive of any amendment or supplement thereto) or as described in such certificate.

(e) (A) At the Execution Time, Ernst & Young, LLP shall have furnished to the Representative a letter, dated as of the Execution Time, in form and substance satisfactory to the Representative, confirming that they are independent accountants within the meaning of the Securities Act and the applicable rules and regulations thereunder and containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained in the Final Memorandum and (B) at the applicable Closing Date, Ernst & Young, LLP shall have furnished to the Representative a letter dated such date, to the effect that they reaffirm the statements made in the letter furnished pursuant to clause (A), except that the specified date referred to shall be a date not more than three business days prior to the applicable Closing Date.

(f) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Final Memorandum, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the business or properties of the Company and its subsidiaries the effect of which, in any case referred to in clause (i) or (ii) above, is, in the reasonable judgment of the Representative, so material and adverse as to make it impractical or inadvisable to market the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereof or thereto).

(g) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Company's debt securities by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Securities Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

Prior to the applicable Closing Date, the Company shall furnish to the Representative such conformed copies of such opinions, certificates, letters and documents as the Representative may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representative and Counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder with respect to the 2002 Debentures, the 2004 Debentures, the 2007 Debentures, the 2017 Debentures, the 7.95% 2027 Debentures, the 6.95% 2027 Debenture, the 7.25% 2027 Debentures, and/or the 2032 Debentures, as the case may be, may be canceled at, or at any time prior to, the applicable Closing Date by the Representative. Notice of such cancellation shall be given to the Company in writing or by telephone or telefax confirmed in writing.

The documents required to be delivered by this Section 6 will be delivered at the office of Counsel for the Initial Purchasers, at 599 Lexington Avenue, New York, New York, on the applicable Closing Date.

7. Reimbursement of Expenses. If the sale of the Securities provided for herein is not consummated because of cancellation by the Representative pursuant to Section 6 hereof, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any material agreement herein or comply with any material provision hereof other than by reason of a default by any of the Initial Purchasers in payment for the Securities on the applicable Closing Date, the Company will reimburse the Initial Purchasers severally upon demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of Counsel for the Initial Purchasers) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in

14

connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Initial Purchasers through the Representative specifically for inclusion therein. The foregoing indemnity with respect to any untrue statement contained in or any omission from the Preliminary Memorandum shall not inure to the benefit of any Initial Purchaser (or the directors, officers, employees or agents of each Initial Purchaser or any person who controls such Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) from whom the person asserting any such loss, claim, damage or liability purchased any of the Securities that are the subject thereof if such person was not sent or given a copy of the Final Memorandum (or any amendment or supplement thereto) at or prior to the written confirmation of the sale of such Securities to such person and the untrue statement contained in or the omission from such Preliminary Memorandum was corrected in the Final Memorandum (or any amendment or supplement thereto), unless such failure resulted from noncompliance by the Company with its obligations hereunder to furnish the Initial Purchasers with copies of the Final Memorandum. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Initial Purchaser severally agrees to indemnify and hold harmless the Company, its directors, its officers, and each person who controls the Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Initial Purchaser, but only with respect to claims and actions based upon written information relating to such Initial Purchaser furnished to the Company by or on behalf of such Initial Purchaser through the Representative specifically for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto). This indemnity agreement will be in addition to any liability which any Initial Purchaser may otherwise have. The Company acknowledges that the statements set forth in the first two sentences of the last paragraph of the cover page, and the first and second sentences of the second paragraph, the second sentence of the third paragraph and the first three sentences of the last paragraph under the heading "Plan of Distribution" in the Preliminary Memorandum and the Final Memorandum constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto).

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above

15

unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), however, the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel only if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded upon advice of counsel that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. An indemnifying party shall not be liable under this Section 8 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise, or consent is consented to by such indemnifying party, which consent shall not be unreasonably withheld.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Initial Purchasers agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company and by the Initial

16

Purchasers from the offering of the Securities; provided, however, that in no case shall any Initial Purchaser (except as may be provided in any agreement among the Initial Purchasers relating to the offering of the Securities) be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder, in each case as set forth on the cover page of the Final Memorandum. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Initial Purchasers shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and of the Initial Purchasers in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses), and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions received by the Initial Purchasers from the Company in connection with the purchase of the Securities hereunder, in each case as set forth on the cover page of the Final Memorandum. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the Company or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchasers' obligations to contribute as provided in this
Section 8(d) are several in proportion to their respective purchase obligations and not joint. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each director, officer, employee and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers

17

agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such non-defaulting Initial Purchasers do not purchase all the Securities within 36 hours of such default, this Agreement will terminate without liability to any non-defaulting Initial Purchaser or the Company except as otherwise provided in Section 11. In the event of a default by any Initial Purchaser as set forth in this Section 9, the applicable Closing Date shall be postponed for such period, not exceeding seven days, as the Representative shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or to any non- defaulting Initial Purchaser for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the applicable Securities, if prior to such time (i) there shall have occurred any change, or any development involving a prospective change, in or affecting particularly the business or properties of the Company or its subsidiaries which, in the judgment of the Representative, materially impairs the investment quality of the Securities, (ii) any downgrading in the rating of any debt securities of the Company by any "nationally recognized statistical rating organization" (as defined for purposes of Rule 436(g) under the Securities Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating), (iii) trading in any of the Company's securities shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or materially limited or minimum prices shall have been established on such exchange, (iv) a banking moratorium shall have been declared either by federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the reasonable judgment of the Representative, impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereof or thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Company or any of the officers, directors or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

18

12. Fees, Expenses. The Company covenants and agrees with the Representative that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company's counsel and accountants in connection with the issue of the Securities and all other expenses in connection with the preparation and printing of the Preliminary Memorandum and Final Memorandum and any amendments and supplements thereto and the mailing and delivering of copies thereof to the Initial Purchasers; (ii) the cost of printing or other production of all documents relating to the offering, purchase, sale and delivery of the Securities as provided in Section 4(a); (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws, including the fees and disbursements of Counsel for the Initial Purchasers in connection with such qualification and in connection with any Blue Sky surveys; (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities;
(vi) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities; (vii) any cost incurred in connection with the designation of the Securities for trading in PORTAL (viii) any fees charged by DTC; and (ix) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this
Section 12, including through payment or reimbursement of any roadshow expenses incurred by or on behalf of the Company. It is understood, however, that except as provided in Sections 7 and 12 hereof, the Initial Purchasers will pay all of their own costs and expenses, including the fees, disbursements and expenses of their counsel and any marketing expenses connected with any offers they may make.

13. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representative, will be mailed, delivered or telefaxed and confirmed to them, care of Salomon Brothers Inc, at Seven World Trade Center, New York, New York, 10048, facsimile (212) 783-2274; or, if sent to the Company, will be mailed, delivered or telefaxed and confirmed to it at One James Center, 901 East Cary Street, Richmond, Virginia 23219, attention: David D. Owen, Managing Director-Corporate Finance, telefax number

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8 hereof, and, except as expressly set forth in Section 5(h) hereof, no other person will have any right or obligation hereunder.

15. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York.

16. Business Day. For purposes of this Agreement, "business day" means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in The City of New York, New York are authorized or obligated by law, executive order or regulation to close.

19

17. Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original, but all such counterparts will together constitute one and the same instrument.

18. Headings. The section headings are for convenience only and shall not affect the construction hereof.

(i) mail to each Holder a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents;

(ii) keep the Registered Exchange Offer open for not less than 30 days (or longer if required by applicable law);

3. Shelf Registration.

(a) The Company shall at its own cost, as promptly as practicable, file with the Commission, and thereafter shall use its best efforts to cause to be declared effective under the Act within 210 days after the Closing Date (or promptly in the event of a request by a Purchaser), a Shelf Registration Statement relating to the offer and sale of the Securities or the Exchange Securities, as applicable, by the applicable Holders from time to time in accordance with the methods of distribution elected by such Holders and set forth in such Shelf Registration Statement; provided that, with respect to Exchange Securities received by a Purchaser in exchange for Securities constituting any portion of an unsold allotment, the Company may, if permitted by current interpretations by the Commission's staff, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Regulation S- K Items 507 and/or 508, as applicable, in satisfaction of its obligations

9

under this paragraph (a) with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement.

(b) The Company shall keep the Shelf Registration Statement continuously effective until the earliest of (i) the second anniversary of the Closing Date (or the first anniversary of the effective date of the Shelf Registration Statement if such Shelf Registration Statement is filed at the request of any Purchaser), (ii) the time when the Securities registered under the Shelf Registration Statement can be sold by non- affiliates pursuant to Rule 144 under the Act without any limitation under clauses (c), (e) (f) and (h) of Rule 144 or (iii) such time when all the Securities covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (in any such case, such period being called the "Shelf Registration Period"); provided, however, that the Company will have the ability to suspend the availability of the Shelf Registration Statement during any consecutive 365-day period for up to two periods of up to 45 consecutive days each, but no more than an aggregate of 60 days during any 365-day period (a "Suspension"), provided that the Company notifies the holder of the Securities covered thereby of any such Suspension.

4. Registration Procedures. In connection with any Shelf Registration Statement and, to the extent applicable, any Exchange Offer Registration Statement, the following provisions shall apply:

(a) The Company shall furnish to the Purchasers, prior to the filing thereof with the Commission, a copy of any Shelf Registration Statement and any Exchange Offer Registration Statement, and each amendment thereof and each amendment or supplement, if any, to the Prospectus included therein, and shall use its best efforts to reflect in each such document, when so filed with the Commission, such comments as you reasonably may propose.

(b) The Company shall ensure that (i) any Registration Statement and any amendment thereto and any Prospectus forming part thereof and any amendment or supplement thereto complies in all material respects with the Act and the rules and regulations thereunder, (ii) any Registration Statement and any amendment thereto does not, when it becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any Prospectus forming part of any Registration Statement, and any amendment or supplement to such Prospectus, does not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements, in the light of the circumstances under which they were made, not misleading.

(c) (1) The Company shall advise you and, in the case of a Shelf Registration Statement, the Holders of Securities covered thereby, and, if requested by you or any such Holder, confirm such advice in writing:

(i) when a Registration Statement and any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective; and

(ii) of any request by the Commission for amendments or supplements to the Registration Statement or the Prospectus included therein or for additional information.

(2) The Company shall advise you and, in the case of a Shelf Registration Statement, the Holders of Securities covered thereby, and, in the case of an Exchange Offer Registration Statement, any Exchanging Dealer which has provided in writing to the Company a telephone or facsimile number and address for notices, and, if requested by you or any such Holder or Exchanging Dealer, confirm such advice in writing of the inability to use the Shelf Registration Statement for resales of the Securities or the Exchange Securities as a result of:

(i) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose;

(ii) the receipt by the Company of any notification with respect to the suspension of the qualification of the securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose;

(iii) a Suspension; and

(iv) the happening of any event that requires the making of any changes in the Registration Statement or the Prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading (which advice shall be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made).


11

(d) The Company shall use its best efforts to prevent the issuance and if issued to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement at the earliest possible time.

(e) The Company shall furnish to each Holder of Securities included within the coverage of any Shelf Registration Statement, without charge, at least one copy of such Shelf Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits (including those incorporated by reference).

(f) The Company shall, during the Shelf Registration Period, deliver to each Holder of Securities included within the coverage of any Shelf Registration Statement, without charge, as many copies of the Prospectus (including each preliminary Prospectus) included in such Shelf Registration Statement and any amendment or supplement thereto as such Holder may reasonably request; and the Company consents to the use of the Prospectus or any amendment or supplement thereto by each of the selling Holders of Securities in connection with the offering and sale of the Securities covered by the Prospectus or any amendment or supplement thereto.

(g) The Company shall furnish to each Exchanging Dealer that so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, any documents incorporated by reference therein, and, if the Exchanging Dealer so requests in writing, all exhibits (including those incorporated by reference).

(h) The Company shall, during the Exchange Offer Registration Period, promptly deliver to each Exchanging Dealer, without charge, as many copies of the Prospectus included in such Exchange Offer Registration Statement and any amendment or supplement thereto as such Exchanging Dealer may reasonably request for delivery by such Exchanging Dealer in connection with a sale of Exchange Securities received by it pursuant to the Registered Exchange Offers; and the Company consents to the use of the Prospectus or any amendment or supplement thereto by any such Exchanging Dealer, as aforesaid.

(i) Prior to the Registered Exchange Offers or any other offering of Securities pursuant to any Registration Statement, the Company shall use its reasonable best efforts to register or qualify or cooperate with the Holders of Securities included therein and their respective counsel in connection with the registration or qualification of such Securities for offer and sale under the securities or blue sky laws of such jurisdictions as any such Holders reasonably request in writing and do any and all other acts or things necessary or advisable to enable the


12

offer and sale in such jurisdictions of the securities covered by such Registration Statement; provided, however, that the Company will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process or to taxation in any such jurisdiction where it is not then so subject.

(j) Unless the applicable securities shall be in book-entry only form, the Company shall cooperate with the Holders of Securities or Exchange Securities to facilitate the timely preparation and delivery within the times required by normal way of settlement of certificates representing securities to be sold pursuant to any Registration Statement free of any restrictive legends and in such authorized denominations and registered in such names as Holders may request prior to sales of securities pursuant to such Registration Statement.

(k) Upon the occurrence of any event contemplated by paragraphs
(c)(1)(ii) or (c)(2)(iv) above, the Company shall promptly prepare a post- effective amendment to any Registration Statement or an amendment or supplement to the related Prospectus or file any other required document so that, as thereafter delivered to purchasers of the securities included therein, the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(l) Not later than the effective date of any Shelf Registration Statement hereunder, the Company shall provide a CUSIP number for the Securities or Exchange Securities, as the case may be, registered under such Registration Statement, and provide the applicable trustee with printed certificates for such Securities or Exchange Securities, in a form eligible for deposit with The Depository Trust Company.

(m) The Company shall use its best efforts to comply with all applicable rules and regulations of the Commission and shall make generally available to its security holders as soon as practicable after the effective date of the applicable Registration Statement an earnings statement satisfying the provisions of Section 11(a) of the Act.

(n) The Company shall cause the Indenture or the Exchange Securities Indenture, as the case may be, to be qualified under the Trust Indenture Act in a timely manner.

(o) The Company may require each Holder of Securities to be sold pursuant to any Shelf Registration Statement to furnish to the Company such


13

information regarding such Holder and the distribution of such Securities as the Company may from time to time reasonably require for inclusion in such Registration Statement.

(p) The Company shall, if requested by the Managing Underwriters or the Holders of Securities covered by such Shelf Registration Statement incorporate in a Prospectus supplement or post-effective amendment to a Shelf Registration Statement, such information with respect to such Managing Underwriters and Holders as such Managing Underwriters and Majority Holders reasonably agree should be included therein and shall make all required filings of such Prospectus supplement or post-effective amendment as soon as practically possible after written notification of the matters to be incorporated in such Prospectus supplement or post-effective amendment.

(q) In the case of any Shelf Registration Statement, the Company shall enter into such agreements (including underwriting agreements) and take all other appropriate actions in order to expedite or facilitate the registration or the disposition of the Securities or the Exchange Securities, as the case may be, and in connection therewith, if an underwriting agreement is entered into, cause the same to contain indemnification provisions and procedures no less favorable than those set forth in Section 6 (or such other provisions and procedures acceptable to the Majority Holders and the Managing Underwriters, if any) with respect to all parties to be indemnified pursuant to Section 6.

(r) If a Shelf Registration Statement is filed pursuant to Section 3, the Company shall make reasonably available for inspection by any selling Holder of such Securities being sold, any underwriter participating in any such disposition of Securities, if any, and any attorney, accountant or other agent retained by any such selling Holder or underwriter (collectively, the "Inspectors"), at the offices where normally kept, during reasonable business hours, all financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries (collectively, the "Records") as shall be reasonably necessary to enable them to exercise any applicable due diligence responsibilities, and cause the officers, directors and employees of the Company and its subsidiaries to supply all relevant information in each case reasonably requested by any such Inspector in connection with such Registration Statement; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Holders by the Initial Purchasers and on behalf of the other parties by one counsel designated by the Initial Purchasers. Records which the Company determines, in good faith, to be confidential and any records which the Company notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (i) the disclosure of such Records is necessary to avoid or correct a material misstatement or omission in such Registration Statement,

14

(ii) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or is necessary in connection with any action, suit or proceeding or (iii) the information in such Records has been made generally available to the public. Each selling Holder of such Securities will be required as a condition to the receipt of such information to agree in writing that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company unless and until such is made generally available to the public. Each selling Holder of such Securities will be required to further agree in writing that it will, upon learning that disclosure of such Records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company at its expense to undertake appropriate action to prevent disclosure of the Records deemed confidential; (iii) make such representations and warranties to the Holders of securities registered thereunder and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement; (iv) obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the Managing Underwriters, if any) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Holders and underwriters (it being agreed that the matters to be covered by such opinion may be subject to customary qualifications and exceptions); (v) obtain "cold comfort" letters and updates thereof from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial statements and financial data are, or are required to be, included in the Registration Statement), addressed to each selling Holder of Securities registered thereunder and the underwriters, if any, in customary form and covering matters of the type customarily covered in "cold comfort" letters in connection with primary underwritten offerings; and (vi) deliver such documents and certificates as may be reasonably requested by the Majority Holders and the Managing Underwriters, if any, including those to evidence compliance with Section 4(k) and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company. The foregoing actions set forth in clauses (iii), (iv), (v) and (vi) of this Section 4(r) shall be performed at (A) the effectiveness of such Registration Statement and each post- effective amendment thereto and (B) each closing under any underwriting or similar agreement as and to the extent required thereunder.

5. Registration Expenses. The Company shall bear all expenses incurred in connection with the performance of its obligations under Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will reimburse the Holders for the

15

reasonable fees and disbursements of one firm or counsel, reasonably satisfactory to the Company, designated by the Majority Holders to act as counsel for the Holders in connection therewith, and, in the case of any Exchange Offer Registration Statement, will reimburse the Purchasers for the reasonable fees and disbursements of one counsel, reasonably satisfactory to the Company, acting in connection therewith.

6. Indemnification and Contribution. (a) In connection with any Registration Statement, the Company agrees to indemnify and hold harmless each Holder of Securities or Exchange Securities, as the case may be, covered thereby (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and agents of each such Holder and each person who controls any such Holder within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any preliminary Prospectus or Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any such Holder specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

The Company also agrees to indemnify or contribute to Losses of, as provided in Section 6(d), any underwriters of Securities or Exchange Securities registered under a Shelf Registration Statement, their officers and directors and each person who controls such underwriters on substantially the same basis as that of the indemnification of the Purchaser and the selling Holders provided in this Section 6(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 4(q) hereof.

(b) Each Holder of Securities or Exchange Securities covered by a Registration Statement (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally agrees to


16

indemnify and hold harmless (i) the Company, (ii) each of its directors, (iii) each of its officers who signs such Registration Statement and (iv) each person who controls the Company within the meaning of either Section 15 of the Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to each such Holder, but only with reference to claims and actions based upon written information relating to such Holder furnished to the Company by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this
Section 6, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above or paragraph (d) below unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and
(ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), however, the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (and local counsel) only if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded upon advice of counsel that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement,

17

compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. An indemnifying party shall not be liable under this Section 6 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise, or consent is consented to by such indemnifying party, which consent shall not be unreasonably withheld.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 6 is unavailable to or insufficient to hold harmless an indemnified party for any reason, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other hand, from the Initial Placement and the Registration Statement which resulted in such Losses; provided, however, that in no case shall any Purchaser or any subsequent Holder of any Security or Exchange Security be responsible, in the aggregate, for any amount in excess of the purchase discount or commission applicable to such Security, or in the case of an Exchange Security, applicable to the Security which was exchangeable into such Exchange Security, as set forth on the cover page of the Final Memorandum, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Registration Statement which resulted in such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the sum of (x) the total net proceeds from the Initial Placement (before deducting expenses) as set forth on the cover page of the Final Memorandum and (y) the total amount of additional interest which the Company was not required to pay as a result of registering the securities covered by the Registration Statement which resulted in such Losses. Benefits received by the Purchasers shall be deemed to be equal to the total purchase discounts and commissions as set forth on the cover page of the Final Memorandum, and benefits received by any other Holders shall be deemed to be equal to the value of the net proceeds received by such Holder from the sale of Securities or Exchange Securities, as applicable, registered under the Act. Benefits received by any underwriter shall be deemed to be equal to the total underwriting discounts and commissions, as set forth on the cover page of the Prospectus forming a part of the Registration Statement

18

which resulted in such Losses. Relative fault shall be determined by reference to whether any alleged untrue statement or omission relates to information provided by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person who controls a Holder within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

(e) The provisions of this Section 6 will remain in full force and effect, regardless of any investigation made by or on behalf of any Holder, the Company or any of the officers, directors or controlling persons referred to in this Section 6, and will survive the sale by a Holder of securities covered by a Registration Statement.

7. Miscellaneous.

(a) No Inconsistent Agreements. The Company has not, as of the date hereof, entered into, nor shall it, on or after the date hereof, enter into, any agreement with respect to the Securities that is inconsistent with the rights granted to the Holders herein or otherwise conflicts with the provisions hereof.

(b) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of the Holders of at least a majority of the then outstanding aggregate principal amount of Securities (or, after the consummation of any Exchange Offer in accordance with Section 2 hereof, of Exchange Securities); provided that, with respect to any matter that directly or indirectly affects the rights of any Purchaser hereunder, the Company shall obtain the written consent of each such Purchaser against which such amendment, qualification, supplement, waiver or consent is to be effective. Notwithstanding the foregoing (except the foregoing proviso), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Securities are being sold pursuant to a Registration

19

Statement and that does not directly or indirectly affect the rights of other Holders may be given by the Majority Holders, determined on the basis of securities being sold rather than registered under such Registration Statement.

(c) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail, telex, telecopier, or air courier guaranteeing overnight delivery:

(1) if to a Holder, at the most current address given by such Holder to the Company in accordance with the provisions of this Section 7(c), which address initially is, with respect to each Holder, the address of such Holder maintained by the Registrar under the Indenture, with a copy in like manner to Salomon Brothers Inc;

(2) if to you, initially at the address set forth in the Purchase Agreement; and

(3) if to the Company, initially at its address set forth in the Purchase Agreement.

All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when answered back, if telexed; when receipt is acknowledged, if telecopied; and on the next Business Day, if timely delivered to an air courier guaranteeing overnight delivery.

The Purchasers or the Company by notice to the other may designate additional or different addresses or telex or telecopy numbers for subsequent notices or communications.

(d) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including, without the need for an express assignment or any consent by the Company thereto, subsequent Holders of Securities and/or Exchange Securities. The Company hereby agrees to extend the benefits of this Agreement to any Holder of Securities and/or Exchange Securities and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto.

(e) Counterparts. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

20

(f) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

(g) Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed in said State.

(h) Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law.

(i) Securities Held by the Company, etc. Whenever the consent or approval of Holders of a specified percentage of principal amount of Securities or Exchange Securities is required hereunder, Securities or Exchange Securities, as applicable, held by the Company or its Affiliates (other than subsequent Holders of Securities or Exchange Securities if such subsequent Holders are deemed to be Affiliates solely by reason of their holdings of such Securities or Exchange Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

Please confirm that the foregoing correctly sets forth the agreement between the Company and you.

Very truly yours,

CSX CORPORATION

ANNEX A

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Securities where such Exchange Securities were acquired by such broker-dealer as a result of market-making activities or other trading activities. The Company has agreed that, starting on the Expiration Date (as defined in the Exchange Offer) and ending on the close of business 180 days after the consummation of the Exchange Offer, it will make this Prospectus available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution".


ANNEX B

Each broker-dealer that receives Exchange Securities for its own account in exchange for Securities, where such Securities were acquired by such broker- dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any sale or transfer of the Exchange Securities. See "Plan of Distribution."


ANNEX C

PLAN OF DISTRIBUTION

Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Securities where such Securities were acquired as a result of market-making activities or other trading activities. The Company has agreed that, starting on the Expiration Date and ending on the close of business on the first anniversary of the Expiration Date, it will make this Prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

The Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such Exchange Securities may be deemed to be an "underwriter" within the meaning of the Act and any profit from any such resale of Exchange Securities and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Act. The Letter of Transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker- dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Act.

For a period of 180 days after the consummation of the Exchange Offer, the Company will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all expenses incident to the Exchange Offer (including the expenses of one counsel for the holders of the Securities) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Securities (including any broker-dealers) against certain liabilities, including liabilities under the Act.
