                     Supplemental Retirement Benefit Plan
                of CSX Corporation and Affiliated Corporations

                    As Amended and Restated January 1, 1995
                      (As Amended through June 27, 2000)

Section I - INTRODUCTION
------------------------

     1.   The purpose of this plan, hereinafter called the "Supplemental Plan",
is to provide benefit payments to individuals who are participants (or members,
as the case may be) in funded, tax-qualified defined benefit pension plans
maintained by CSX Corporation (the "Company") and certain of its affiliated
corporations (whose participation in the Supplemental Plan is approved by the
Compensation Committee of the Board of Directors of the Company ("Compensation
Committee")) and which adopts this Supplemental Plan by action of its board of
directors and whose benefits would otherwise be reduced by Section 415 of the
Internal Revenue Code ("Code") of 1986, as amended ("Code") which imposes
limitations on benefits which may be accrued under such plans ("Code
Limitations"). Notwithstanding the preceding, following a Change of Control, an
affiliated corporation may not become a participating employer in this
Supplemental Plan without the approval of the Benefits Trust Committee.

     2.   This Supplemental Plan preserves and continues in effect all
provisions for accruals based upon limitations of benefits imposed by Code
Limitations, heretofore credited to Participants under Section V, paragraph
(subsection) 5, of the Special Retirement Plan of CSX Corporation and Affiliated
Corporations ("Special Plan"), the Supplemental Benefits Plan of Sea-Land
Corporation and Participating Companies, and the American Commercial Lines
Benefit Restoration Plan ("Predecessor Plans").

Section II - DEFINITIONS
------------------------

     1.   Supplemental Benefit means the benefit described in Section IV of this
Supplemental Plan.

     2.   The Supplemental Plan shall, where appropriate, refer to and have
meanings consistent with all of the relevant terms of the CSX Pension Plan and
any other regularly maintained funded, tax-qualified defined benefit pension
plan of any other corporation affiliated with the Company whose participation in
the Supplemental Plan as a participating employer is approved by the board of
directors of any such affiliated corporation and by the Compensation Committee.
Such existing regularly maintained defined benefit pension plans which provided
benefits for employees of the Company or its affiliates prior to the Effective
Date of this Supplemental Plan document, or those which may be established
hereafter, as amended from time to time, shall be referred to herein as the
"Pension Plan."

     3.   Regardless of formal differences which may exist between the
Supplemental Plan and the Pension Plan or the Predecessor Plans in the use of
terminology, the definitions and principles which are set forth in the Pension
Plan or the Predecessor Plans with respect to compensation, average
compensation, credited service and similar terms shall be construed and applied
hereunder in a manner consistent with the purposes of this Supplemental Plan and
the Pension Plan or the Predecessor Plans. In
<PAGE>

any instance in which the male gender is used herein, it shall also include
persons of the female gender in appropriate circumstances.

     4.   "Benefits Trust Committee" means the committee created pursuant to the
CSX Corporation and Affiliated Companies Benefits Assurance Trust Agreement (the
"Benefits Assurance Trust").

     5.   Any reference to the "Company's independent actuary", "independent
actuaries", "actuary" or "Actuary" means the independent actuary engaged by CSX
Corporation and, if selected or changed following a Change of Control, approved
by the Benefits Trust Committee.

Section III - MEMBERSHIP
------------------------

     1.   Every person who previously participated in a Predecessor Plan shall
automatically be a Participant in this Supplemental Plan on and after the
Effective Date.

     2.   Each employee who is a Participant in a Pension Plan on or after the
Effective Date shall participate in this Supplemental Plan to the extent of the
benefits provided herein.

     3.   A Participant's participation in this Supplemental Plan shall
terminate coincident with the termination of such individual's participation in
the Pension Plans; provided, however, in the event that the Participant shall be
reassigned or transferred into the employ of the Company or any of its
affiliates which also is a participating employer in this Supplemental Plan, the
Participant's participation shall be continued.

Section IV - SUPPLEMENTAL BENEFITS
----------------------------------

     1.   All of the provisions, conditions and requirements set forth in the
applicable Pension Plan with respect to the granting and payment of retirement
benefits thereunder shall be equally applicable to the payment of supplemental
benefits hereunder to affected Participants in the Supplemental Plan and to the
payment thereof from the employer's general assets.  Whenever an individual
Participant's rights under the Supplemental Plan are to be determined,
appropriate reference shall be made to the particular Pension Plan in which such
person is also a participant.  Notwithstanding the preceding sentence, if a
supplemental benefit under this Supplemental Plan shall be paid to a surviving
spouse or other surviving designated beneficiary in conformance with the
provisions of the Pension Plans, the final installment payment hereunder shall
be made to the estate of the surviving spouse or other surviving designated
beneficiary.

     2.   Each Participant shall receive a Supplemental Benefit under this
Supplemental Plan in an amount equal to the difference, if any, between (i) the
Participant's monthly retirement income benefit under the provisions of the
particular Pension Plan in which such person is also a participant calculated
before the application of any Code Limitations and (ii) the Participant's
monthly retirement income benefit determined after application of the Code
Limitations.

                                      -2-
<PAGE>

     3.   Notwithstanding any other provision of this Supplemental Plan to the
contrary, a Supplemental Benefit shall not be determined or paid which would
duplicate a payment of benefit provided to a Participant under the Pension Plan,
the Predecessor Plans or any other unfunded or funded retirement plan of the
Company or any of its affiliated corporations.  Further, the obligations of the
Company or any of its affiliated companies and the benefit plan due any
Participant, surviving spouse or beneficiary hereunder shall be reduced by any
amount received in regard thereto from the Benefits Assurance Trust or any
similar trust or other vehicle.

     4.   A Supplemental Benefit payable under the provisions of this
Supplemental Plan shall be paid in such forms and at such times as shall be
consistent with the payment of the Participant's retirement income benefit under
the particular Pension Plan in which such person is also a participant.
Notwithstanding the foregoing, prior to a Change of Control, the Company may
delay payment of a Supplemental Benefit under the Supplemental Plan to any
Participant who is determined to be among the top five most highly paid
executives for the year that the Supplemental Benefit payment would otherwise be
paid; provided, however, if a Participant's payment is delayed, that will not
decrease the total Supplemental Benefit to which he is entitled. Notwithstanding
the preceding, following a Change of Control, the authority to delay payment of
a Supplemental Benefit rests solely with the Benefits Trust Committee.

     5.   Notwithstanding any other provision of this Supplemental Plan to the
contrary, the Chief Executive Officer of the Company (the "CEO") may designate
certain senior executives of the Company or its affiliates as eligible to elect,
prior to the commencement of their retirement benefits under the Company's
qualified pension plan, to receive (or for a beneficiary to receive in the event
of the executive's death) the actuarial present value of their benefits under
this Supplemental Plan in a lump sum. Such election shall be made in accordance
with rules established by the Plan Administrator and shall not be effective
until six months after it is made.  An election may be changed at any time prior
to commencement of retirement benefits, but such change shall not be effective
until six months after it is made.  For purposes of this subsection 5,
"actuarial present value" shall be determined as of the date of the payment of
the benefit using the UP 1994 Mortality Table, set back one year, and a discount
rate of 5%, or other such rate as the Compensation Committee may establish from
time to time.  A Participant as to whom a lump sum distribution has been elected
may also elect to lock in, by notifying the Plan Administrator in writing, the
applicable discount rate for three calendar years beyond the year in which the
election to do so is made (or such longer or extended period as the CEO may from
time to time approve).  At least six (6) months advance notice will be provided
with respect to any proposed change in the manner or basis in which the discount
rate to be used to calculate lump sums is determined.  Further, in the event of
a Change of Control, the Benefits Trust Committee shall assume all
responsibilities of the CEO and the Chairman of the Compensation Committee under
this subsection.

Section V - FUNDING METHOD
--------------------------

     1.   The Supplemental Benefit shall be paid exclusively from the general
assets of the applicable employers participating in the Supplemental Plan or
from the Benefits Assurance Trust which has been established to secure the
payment of the obligations created herein. No Participant or other person shall
have any rights or claims against the assets of the employers or against the
Benefits Assurance Trust which are superior to or different from the right or
claim of a general, unsecured creditor of any participating employer.

                                      -3-
<PAGE>

     2.   The Supplemental Plan is intended to be unfunded for tax purposes and
for purposes of Title I of ERISA, and constitutes a mere promise by the
participating employer to make benefit payments in the future.

     3.   The employers participating in the Supplemental Plan shall provide all
funds required to pay benefits accrued and to administer this Supplemental Plan.

     4.   To the extent reflected by resolutions of the applicable boards of
directors, obligations for benefits under this Supplemental Plan shall be joint
and several.

Section VI - ADMINISTRATION OF PLAN
-----------------------------------

     1.   Prior to a Change of Control, the Plan Administrator of the CSX
Pension Plan shall be the "Plan Administrator" of this Supplemental Plan and
shall be responsible for the general administration of the Supplemental Plan,
claims review and for carrying out its provisions. Administration of this
Supplemental Plan shall be carried out consistent with the terms and conditions
of the Pension Plan and the Supplemental Plan.

     2.   Following a Change of Control, the Benefits Trust Company may remove
and/or replace the Plan Administrator.

     3.   The Plan Administrator shall have sole and absolute discretion to
interpret the Plan, determine eligibility for and benefits due hereunder.
Decisions of the Plan Administrator regarding participation in and the
calculation of benefits under this Supplemental Plan, shall at all times be
binding and conclusive on Participants, their beneficiaries, heirs and assigns.

     4.   Notwithstanding Subsection 3 above, following a Change of Control,
final benefit determinations for Participants, their beneficiaries, heirs and
assigns and decisions regarding benefit claims under this Supplemental Plan
shall rest with the Benefits Trust Committee or its delegate in its sole and
absolute discretion.

Section VII - CERTAIN RIGHTS AND OBLIGATIONS
--------------------------------------------

     1.   (a)  Prior to a Change of Control the Compensation Committee may
terminate the Supplemental Plan upon the termination of one or more of the
Pension Plans. Prior to a Change of Control the Board of Directors of CSX
Corporation may terminate the Plan at any time for any reason in any manner not
prohibited by law. Following a Change of Control, this Supplemental Plan may not
be terminated without the approval of the Benefits Trust Committee.

          (b)  Prior to a Change of Control, the Board of Directors of the
Company may terminate an affiliated corporation's participation as a
participating employer in this Supplemental Plan for any reason at any time.
Following a Change of Control, an affiliated corporation may not be terminated
from participation as a participating employer without the consent of the
Benefits Trust Company.

                                      -4-
<PAGE>

          (c)  Prior to a Change of Control, an affiliated corporation's board
of directors may terminate that affiliated corporation's participation as a
participating employer for any reason at any time. Following a Change of
Control, an affiliated corporation's participation as a participating employer
may not be terminated without the consent of the Benefits Trust Committee.

     2.   The participating employers agree in the event that the Supplemental
Plan is terminated:

     (a)  Each retired Participant, surviving spouse of a retired Participant or
          surviving designated beneficiary of a retired Participant shall be
          entitled to receive the Supplemental Benefit they would have received
          had the Supplemental Plan not been terminated, and each surviving
          spouse or surviving designated beneficiary of a deceased Participant
          shall become entitled to receive for life the Supplemental Benefit
          that such surviving spouse or surviving designated beneficiary would
          have received had the Supplemental Plan not been terminated; and

     (b)  Each active Participant shall be entitled to receive for life the
          Supplemental Benefit he or she would have received had the
          Supplemental Plan not been terminated, calculated on the basis of the
          Supplemental Benefit which had accrued at the time of termination;
          provided, however, that the Participant shall become entitled to such
          Supplemental Benefit only at the time and in accordance with the
          provisions of the Supplemental Plan had it continued in effect.

     (c)  In lieu of paying a Supplemental Benefit in accordance with the
          foregoing provisions, the Plan Administrator, at its election, may
          direct the discharge of all obligations to retired Participants,
          surviving spouses or surviving designated beneficiaries of deceased
          Participants, and active Participants by cash payment of equivalent
          actuarial value or through the provision of immediate or deferred
          annuities or such other periodic payments of equivalent actuarial
          value, as it shall in its sole discretion determine.  Notwithstanding
          the preceding, any such action taken by the Plan Administrator
          following  a Change of Control is subject to the approval of the
          Benefits Trust Committee.

     3.   Anything in the Supplemental Plan to the contrary notwithstanding, if
the Plan Administrator finds that any Participant, retired Participant or spouse
is engaged in acts detrimental to the Company or any of its affiliated
corporations, and if after due notice such Participant, the retired Participant
or spouse continues to be so engaged or employed, the Plan Administrator shall
suspend the Supplemental Benefit of such person, which suspension shall continue
until removed by notice from the Plan Administrator; provided, however, that if
such suspension has continued for one year, the Plan Administrator shall
forthwith cancel such Participant's or spouse's Supplemental Benefit.
Furthermore, if the Plan Administrator finds that any Participant had been
discharged for having performed acts detrimental to the Company or any of its
affiliated corporations, then regardless of any other provision in the Pension
Plan or the Supplemental Plan, no benefit shall be payable to or on account of
any such Participant's coverage under this Supplemental Plan. Notwithstanding
the preceding, following a Change of Control, the Plan Administrator shall not
implement such action without the consent of the Benefits Trust Committee.

                                      -5-
<PAGE>

     4.   The establishment of the Supplemental Plan shall not be construed as
conferring any legal rights upon any employee for a continuation of employment,
nor shall it interfere with the rights of an employing corporation to discharge
any employee and to treat him without regard to the effect which such treatment
might have upon him as a Participant in the Supplemental Plan.

Section VIII - NON-ALIENATION OF BENEFITS
-----------------------------------------

     To the extent permitted by applicable law, no benefit under the
Supplemental Plan shall be subject in any manner to anticipation, alienation,
sale, transfer, assignment, pledge, encumbrance, or charge, and any attempt so
to do shall be void, except as specifically provided in the Supplemental Plan,
nor shall any benefit be in any manner liable for or subject to the debts,
contracts, liabilities, engagements, or torts of the person entitled to such
benefits; and in the event that the Plan Administrator shall find that any
active or retired Participant, surviving spouse or surviving designated
beneficiary under the Supplemental Plan has become bankrupt or that any attempt
has been made to anticipate, alienate, sell, transfer, assign, pledge, encumber,
or charge any of his benefits under the Supplemental Plan, expect as
specifically provided in the Supplemental Plan, then such benefits shall cease,
and in that event, the Plan Administrator shall hold or apply the same to or for
the benefit of such active or retired Participant, surviving spouse or surviving
designated beneficiary, in such manner as the Plan Administrator may deem
proper. Notwithstanding the preceding, following a Change of Control, the Plan
Administrator shall not implement such action without the consent of the
Benefits Trust Committee.

Section IX - AMENDMENTS
-----------------------

     The Supplemental Plan represents a contractual obligation entered into by a
participating employer in consideration of services rendered and to be rendered
by Participants covered under the Supplemental Plan, and

     1.   Any Participant in this Supplemental Plan who remains in the active
service of a participating employer shall not be deprived of his or her
participation or benefit which shall accrue under the Supplemental Plan except
as provided hereunder.

     2.   No modification or amendment may be made which shall deprive any
Participant, the surviving spouse of a Participant or the surviving designated
beneficiary of a Participant, without the consent of such Participant, surviving
spouse of a Participant or the surviving designated beneficiary of a
Participant, of any Supplemental Benefit under the Supplemental Plan to which he
or she would otherwise be entitled by reason of the Supplemental Benefit
standing to his or her credit to the date of such modification or amendment, and
in the event of any modification or amendment which adversely affects such
Supplemental Benefit, the amount of all reserves required to be accrued on the
books of a participating employer shall thereupon be determined and accrued, if
the same has not already been done, and such Supplemental Benefit shall become
and remain a fixed liability of the participating employers for the payment of
such benefits accrued to the date of such modification or amendments.

     3.   Subject to the foregoing, prior to a Change of Control, the Board of
Directors of the Company on the recommendation of the Compensation Committee,
reserves the right at any time and from time to time to modify or amend in whole
or in part any or all of the Supplemental Plan.  Following

                                      -6-
<PAGE>

a Change of Control, all amendments to this Supplemental Plan are subject to the
approval of the Benefits Trust Committee.

Section X - CHANGE OF CONTROL
-----------------------------

     1.   If a Change of Control has occurred, the Company and its participating
affiliates shall contribute to the Benefits Assurance Trust within 7 days of
such Change of Control, a lump sum contribution equal to the greatest of:

     (a)  the aggregate value of the amount each Participant would be eligible
          to receive, under Subsection (2), below;

     (b)  the present value of accumulated Plan benefits based on the
          assumptions the Company's independent actuary deems reasonable for
          this purpose, as of the Valuation Date, as defined in subsection (6),
          below, coinciding with or next preceding the date of Change of
          Control, to the extent such amounts are not already in the Benefits
          Assurance Trust.  The aggregate value of the amount of the lump sum to
          be contributed to the Benefits Assurance Trust pursuant to this
          Section X shall be determined by the Company's independent actuaries.
          Thereafter, the Company's independent actuaries shall annually
          determine as of a Valuation Date for each Participant not receiving a
          lump sum payment pursuant to subsection (2), below, the greater of:

          (i)  the amount such Participant would have received under subsection
               (2) had such Participant not made the election under subsection
               (3), below, if applicable; and

          (ii) the present value of accumulated benefits based on assumptions
               the actuary deems reasonable for this purpose.  To the extent
               that the value of the assets held in the Benefits Assurance Trust
               relating to this Supplemental Plan does not equal the amount
               described in the preceding sentence, (and the value of other
               liabilities held in the applicable segregated account of the
               Benefits Assurance Trust), at the time of the valuation, the
               Company shall make a lump sum contribution to the Benefits
               Assurance Trust equal to the difference.

     (c)  the amount determined under Section 1(h) of the Benefits Assurance
          Trust attributable to liabilities relating to this Supplemental Plan.

     2.   In the event a Change of Control has occurred, the trustee of the
Benefits Assurance Trust shall, within 45 days of such Change of Control, pay to
each Participant not making an election under subsection (3), a lump sum payment
equal to the actuarial present value of the aggregate supplemental benefit each
Participant (or any beneficiary of a Participant) has accrued as of the
Valuation Date preceding the date of such Change of Control. If a Participant's
benefit has not commenced as of such date, such lump sum shall be determined
assuming that:

     (a)  The Participant's benefit would commence at the earliest date he would
          qualify for early or normal retirement under the Plan, were his
          employment with the Company to

                                      -7-
<PAGE>

          continue, but in no event earlier than the later of age 55 or the date
          of such Change of Control.

     (b)  The Participant would qualify for an early (or normal) retirement
          benefit as of the date determined in (a).

     (c)  If married, the Participant would receive his benefit under the 50%
          Joint and Survivor form of payment with the spouse as beneficiary; if
          not married, the benefit would be payable in the form of a single life
          annuity.

     "Actuarial present value" shall be determined using the UP 1994 Mortality
Table, set back one year, and a discount rate of 5%, or other such rate as the
Compensation Committee may establish from time to time, or, where applicable
and, if lower, the "lock in rate" elected by a Participant pursuant to
Subsection 5 of Section IV and in effect.  Discount rates producing lower lump
sums not in effect for at least six (6) months at the time of a Change of
Control shall be disregarded.

     3.   Each Participant may elect in a time and manner determined by the
Compensation Committee but, in no event later than December 31, 1996, or the
occurrence of a Change of Control, if earlier, to have amounts and benefits
determined and payable under the terms of this Supplemental Plan as if a Change
of Control had not occurred.  New Participants in the Plan may elect in a time
and manner determined by the Compensation Committee, (or, after a Change of
Control, the Benefits Trust Committee) but in no event later than 90 days after
becoming a Participant, to have amounts and benefits determined and payable
under the terms of this Supplemental Plan as if a Change of Control had not
occurred.  A Participant who has made an election,  as set forth in the two
preceding sentences, may, at any time and from time to time, change that
election; provided, however, a change of election that is made within one year
of a Change of Control shall be invalid.

     4.   Notwithstanding anything in this Supplemental Plan to the contrary,
each Participant who has made an election under subsection (3), above, may elect
within 90 days following a Change of Control, in a time and manner determined by
the Benefits Trust Committee, to receive a lump sum payment calculated under the
provisions of subsection (2), above, determined as of the Valuation Date next
preceding such payment, except that such amount shall be reduced by 5% and such
reduction shall be irrevocably forfeited to the Company or the applicable
participating employer by the Participant. Furthermore, as a result of such
election, the Participant shall no longer be eligible to participate or
otherwise benefit under the Supplemental Plan. Payments under this subsection
(4) shall be made not later than 7 days following receipt by the Benefits Trust
Committee of the Participant's election. The Benefits Trust Committee shall, no
later than 7 days after a Change of Control has occurred, cause written
notification to be given to each Participant eligible to make an election under
this subsection (4), that a Change of Control has occurred and informing such
Participant of the availability of the election.

     5.   As used in this Section X, a "Change of Control" shall mean:

     (a)  Stock Acquisition.  The acquisition by any individual, entity or group
          -----------------
          [within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities
          Exchange Act of 1934, as amended (the "Exchange Act")] (a "Person") of
          beneficial ownership (within the meaning of Rule 13d-3 promulgated
          under the Exchange Act) of 20% or more of either (i) the then

                                      -8-
<PAGE>

          outstanding shares of common stock of the Company (the "Outstanding
          Company Common Stock"), or (ii) the combined voting power of the then
          outstanding voting securities of the Company entitled to vote
          generally in the election of directors (the "Outstanding Company
          Voting Securities"); provided, however, that for purposes of this
                               --------  -------
          subsection (a), the following acquisitions shall not constitute a
          Change of Control:  (i) any acquisition directly from the Company;
          (ii) any acquisition by the Company; (iii) any acquisition by any
          employee benefit plan (or related trust) sponsored or maintained by
          the Company or any corporation controlled by the Company; or (iv) any
          acquisition by any corporation pursuant to a transaction which
          complies with clauses (i), (ii) and (iii) of subsection (c) of this
          Section X(5); or

     (b)  Board Composition.  Individuals who, as of the date hereof, constitute
          -----------------
          the Board of Directors (the "Incumbent Board") cease for any reason to
          constitute at least a majority of the Board of Directors; provided,
                                                                    --------
          however, that any individual becoming a director subsequent to the
          -------
          date hereof whose election or nomination for election by the Company's
          shareholders, was approved by a vote of at least a majority of the
          directors then comprising the Incumbent Board shall be considered as
          though such individual were a member of the Incumbent Board, but
          excluding, for this purpose, any such individuals whose initial
          assumption of office occurs as a result of an actual or threatened
          election contest with respect to the election or removal of directors
          or other actual or threatened solicitation of proxies or consents by
          or on behalf of a Person other than the Board of Directors; or

     (c)  Business Combination.  Approval by the shareholders of the Company of
          --------------------
          a reorganization, merger or consolidation, or sale or other
          disposition of all or substantially all of the assets of the Company
          or its principal subsidiary that is not subject, as a matter of law or
          contract, to approval by the Interstate Commerce Commission or any
          successor agency or regulatory body having jurisdiction over such
          transactions (the "Agency") (a "Business Combination"), in each case,
          unless, following such Business Combination:
          ------

          (i)  all or substantially all of the individuals and entities who were
               the beneficial owners, respectively, of the Outstanding Company
               Common Stock and Outstanding Company Voting Securities
               immediately prior to such Business Combination beneficially own,
               directly or indirectly, more than 50% of, respectively, the then
               outstanding shares of common stock and the combined voting power
               of the then outstanding voting securities entitled to vote
               generally in the election of directors, as the case may be, of
               the corporation resulting from such Business Combination

     1.  Purpose. The CSX Long Term Incentive Cash Program (the "Program") for
the 2000-2002 Performance Period is intended to provide long term cash
incentives to select management employees to improve CSX's financial
performance, and to reward such employees with a cash payment if CSX's
performance pursuant to the terms of the Program are met. The Program shall be
operated as Performance Grants under the provisions of Section 8 of the CSX
Omnibus Incentive Plan.

     2.  Definitions.  As used in the Program, the following terms have the
meanings indicated below. All other capitalized terms have the definitions in
the CSX Omnibus Incentive Plan:

          (a) "Award Matrix" means a matrix which contains the Performance Goals
     selected by the Committee for the Performance Period and other objective
     factors necessary to determine the amount, if any, of the Long Term Award
     for the Performance Period.

          (b) "Cash Unit" means a unit with a value of $1.00 that is designated
     as part of a Long Term Grant.

          (c) "Long Term Award" means a payment of cash at the end of the
     Performance Period based on the terms of the Long Term Grant.

          (f) "Peer Group" means a group of public companies that the Committee
     determines to be appropriate competitors of CSX for purposes of performance
     comparison. During a Performance Period, the Peer Group shall be adjusted

          (j) "Program" means the CSX Long Term Incentive Cash Program for the
2000-2002 Performance Period.

3.   Participation.

          (a) All present and future management employees of CSX or a Subsidiary
shall be eligible to receive Long Term Grants under the Program. The Committee
shall have the power and complete discretion to select eligible employees to
receive Long Term Grants and to determine for each employee the terms and
conditions of each Long Term Grant.

          (b) A person who becomes eligible to participate at any time after the
commencement of a Performance Period or a Participant whose employment
terminates during a Performance Period because of death, Retirement, or
Disability shall be eligible to receive a pro rata Long Term Grant based on the
ratio that the Participant's number of full months of participation during the
Performance Period bears to the number 36. A Participant who is removed from the
original position held when the Long Term Grant was made or whose employment
terminates during the Performance Period for reasons other than death,
Retirement, Disability, or involuntary separation for reasons other than Cause
shall forfeit any outstanding Long Term Grant, unless otherwise provided by the
Committee.

          (c) A Participant in this Program shall be eligible to participate in
other cash incentive or profit sharing plans established or maintained by CSX or
any Subsidiary. No award under any other incentive or profit sharing plan
maintained by CSX may be made contingent, in whole or in part, on the
Participant not receiving payment of a Long Term Award under this Program.

4.   Determination of Awards.

         (a) Before or within ninety days of the beginning of each Performance
Period, the Committee will select one or more Performance Criteria, the
appropriate Performance Goals for the Performance Criteria, and number of Cash
Units for each Participant with respect to which a Long Term Grant may be made.
The Committee's determinations shall be set forth in an Award Matrix. The
Committee shall consult with senior management executives of CSX to the extent
deemed appropriate by the Committee. Performance Criteria may be used singularly
or in combination, as the Committee determines. The Award Matrix will fix the
objective components for determining whether a Long Term Award will be paid and,
if so, the amount of the Long Term Award. Long Term Awards shall be based on a
percentage of each Participant's Cash Units for the Performance Period if and to
the extent the Performance Goal is achieved. The amount payable to a Participant
for the Performance Period will be determined from the Award Matrix as a
percentage of the Cash Units if the actual performance under a Performance Goal
is within the range fixed by the Committee for the Performance Period

                                       2
<PAGE>

     to generate a payment under the Award Matrix. As determined by the
     Committee, Performance Criteria shall be calculated in accordance with
     public financial statements of CSX and the Peer Group

          (b) The Committee may establish such threshold requirements for the
     payment of a Long Term Award as the Committee shall deem appropriate. Once
     fixed, the Performance Criteria and Performance Goals for a Performance
     Period may not be modified as to a Covered Employee, except as provided in
     Section 4(d).

          (c) Before any Long Term Award may be paid for a Performance Period,
     the Committee shall certify in writing that the Performance Goals and any
     other requirements of the Program have been satisfied for the Performance
     Period.

          (d) Even though the Performance Goals have been met, the Committee may
     reduce or eliminate entirely any Long Term Award to a Participant if the
     Committee determines that such action is in the best interests of CSX. Any
     action by the Committee under this Section 4(d) shall be conclusive and
     binding on CSX and the Participant.

          (e) It is the intent of the Committee that this Program and any Long
     Term Grant satisfy, and be interpreted in a manner to satisfy, the
     applicable requirements of Code Section 162(m) with respect to a Covered
     Employee. If any provision of this Program or if any Long Term Grant would
     otherwise conflict with the expressed intent of this Section 4(e), that
     provision shall be interpreted so as to avoid such conflict to the extent
     possible.

     5. Payment of Long Term Awards. All Long Term Grants will be paid in cash.

     6. Administration. The Committee shall administer the Program under the
terms and conditions of the Plan.

     7. Effective Date of the Program. The effective date of the Program is
January 1, 2000.

     8. Amendment and Termination. This Program shall continue until the end of
the 2002 fiscal year. The Program may be amended or terminated as provided under
the Plan.
