Supplemental Retirement Benefit Plan
                 of CSX Corporation and Affiliated Corporations

                     As Amended and Restated January 1, 1995
                      (As Amended through December 7, 1999)

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 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.

        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,  certain  senior  executives  of the  Company  or its  affiliates  (as
identified  by the Chief  Executive  Officer of the Company  from time to time),
will,  prior to their  commencement  of retirement  benefits under the Company's
qualified  pension  plan,  be  permitted  to elect to  receive  (or  elect 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 in  accordance  with rules  established  by the  Supplemental
Plan's Administrator.  For purposes of this subsection 5, the `actuarial present
value' shall be determined as of the  Valuation  Date  preceding the date of the
payment of the benefit and on the basis of the UP 1984 Mortality Table, set back
one year,  and a discount  rate equal to the interest  rate  promulgated  by the
Pension Benefit  Guaranty  Corporation for use in determining the sufficiency of
single employer defined benefit pension plans terminating on that date.

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.

        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.

               (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.

        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 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  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.

        The  actuarial  present value shall be determined on the basis of the UP
1984  Mortality  Table,  set back one year,  and a  discount  rate  equal to the
interest rate promulgated by the Pension Benefit Guaranty Corporation for use in
determining  the  sufficiency of single  employer  defined benefit pension plans
terminating on the date of such Change in Control.

        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  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

               Common Stock.

        (b)    The Committee may impose conditions  and/or  restrictions as part
               of a Stock  Award and  specify  the terms or  circumstances  upon

               conditions previously imposed on an award of Common Stock.

        (d)    A  Participant  who receives base  compensation  in excess of a
               dollar level to be determined by   the  Committee  and  who  is
               eligible  to receive  an  award  under  the  Company's  Incentive
               Compensation  Program  ("ICP") may elect,  by the  prescribed
               election form with the Company in    accordance  with rules
               established by the  Committee,  to receive all or part of his
               annual ICP award in shares of the  Company's  common  stock,
               rather  than  cash;  provided,  however,  the   Participant  must
               agree that his receipt of the stock will be deferred  until his
               retirement or  termination  of  employment,  with a minimum
               deferral  period of three (3) years.  Elections to   defer are
               irrevocable.  A Participant who makes such election shall, at the
               time that the stock is deferred  receive an  additional  award of
               stock  equal to a  percentage established  by the Committee  from
               time to time,  of the  amount  that he  elected  to have deferred
               (the  "Stock Premium"). The Participant's election to defer shall
               also apply to the Stock Premium.

               If a Participant made an effective  election to defer the payment
               of shares of common  stock and  receive  the Stock  Premium,  the
               Company  shall,  within a  reasonable  period  of time  after the
               deferral  election is made,  transfer  shares of common  stock or
               other  assets  equal in value to the number of shares as to which
               payment  is  deferred  to  the  Trust  to  secure  the  Company's
               obligation  to pay shares of common stock to the  Participant  in
               the future.  However,  in any event,  the Company  shall make any
               previously deferred payment of shares to the Participant upon:

               (1)    the death of the Participant;

               (2)    the Disability of the Participant;

               (3)    the  Participant's  termination  of  employment  with  the
                      Company  or a  Subsidiary,  subject  to the  Participant's
                      deferral   election  and  the  three  (3)  year   deferral
                      requirement;

               (4)    a Divisive Transaction, subject to the Participant's
                      deferral elections; or

               (5)    a Change of Control.

        (e)    The  obligations  of  the  Company  and  any  of  its  affiliated
               corporations  and  the  benefit  due any  Participant,  surviving
               spouse or  beneficiary  hereunder  shall be reduced by any amount
               received in regard  thereto under the Trust or any similar trust,
               trusts or other vehicle.

        (f)    Notwithstanding the preceding, following a Change of Control, the
               authority  to delay  payment  of a  Participant's  benefit  rests
               solely with the Benefits Trust Committee.

6.      Contributions to the Trust.

(a)            The  Company  shall make  contributions  to the Trust to secure a
               source of future payments with respect to Participant's  deferral
               elections pursuant to Section 5. The Trustee shall be responsible
               only for contributions  actually received by it hereunder and the
               Trustee shall have no duty or responsibility  with respect to the
               timing,  amounts,  and sufficiency of contributions made or to be
               made by the Company hereunder.

(b)            The Company may make contributions to the Trust in Common Stock.

(c)            A separate  bookkeeping account (an "Account") shall be
               established by the Trustee for each Participant   covered  by the
               Trust  pursuant  to the  Plan, as  directed  in  writing  by  the
               Company.  A  Participant  may have more than one Account.  Each
               Account is intended to represent  the amount  of a  Participant's
               deferred and unpaid  benefit under the Plan.  The value of a
               Participant's Account at any time will  equal the fair  market
               value of the number of shares of Common  Stock owed to a
               Participant  under this Plan at such time.  The number of shares
               owed at any time will equal the number of shares of Common Stock
               which were  originally  deferred by the  Participant,    plus the
               number of Common Stock shares which could have been acquired if
               dividends  subsequently  declared  by the  Company had been paid
               with  respect to such  shares and  reinvested  in Common   Stock,
               less shares actually  distributed to the Participant  pursuant to
               the Plan.  Account may also mean  individual  sub-accounts  which
               have been or may be established under the Plan from time to time.

(d)            Within sixty days  following the close of each calendar  year, or
               more  frequently  or at such other time as may be required by the
               Trust  Agreement,  the Trustee shall provide the Company and each
               Participant   with  a  written   statement  of  Account  of  each
               Participant.

7.      Options.

(a)            Options  will  consist  of  options  to  purchase  shares  of the
               Company's  common  stock at  purchase  prices  not less  than 100
               percent of the Fair Market Value of such common stock on the date
               of grant.

(b)            Options will be exercisable  upon the date or dates  specified in
               an  Option  agreement  entered  into with a  Participant  but not
               earlier  than one year after the date of grant of the Options and
               not later than 15 years  after the date of grant of the  Options;
               provided,  however,  that  whether  or not the  one-year  holding
               requirement is satisfied, any Exercisability  Requirement must be
               satisfied.

(c)            Any Participant may exercise an Option to purchase stock upon the
               date or dates specified in the Option  agreement  offered to him.
               In no case may an Option be exercised  for a fraction of a share.
               Except as set forth in Section 8, no Option  holder may  exercise
               an  Option  unless  at the  time of  exercise  he has been in the
               continuous  employ of the Company or a Subsidiary since the grant
               of his  Option.  An Option  holder  under this Plan shall have no
               rights as a shareholder with respect to any shares subject to the
               Option until such shares have been issued.

(d)            For purposes of this section, written  notice of exercise must be
               received by the Corporate Secretary of the  Company,  not earlier
               than one year nor later than 15 years after the Option is
               granted.  Such notice must state the number of shares being
               exercised and must be accompanied by payment of the full purchase
               price of such  shares.  Payment  for the  shares  for  which an
               Option is  exercised may be made by (1) a personal check or money
               order payable to CSX  Corporation;  (2) a  tender by the employee
               (in accordance with  procedures  established by the Company) of
               shares of  the  Company's  common  stock  having a Fair  Market
               Value on the date of tender  equaling  the purchase  price of the
               shares for which the Option is being  exercised;  (3) the
               delivery  of a  properly  executed  exercise  notice,  together
               with  irrevocable  instructions  to a broker to promptly  deliver
               to the Company  either sale proceeds of shares sold to pay the
               purchase  price or the amount loaned by the broker to pay the
               purchase  price;  or (4) any  combination  of (1), (2) and (3).

8.      Separation from Employment and Divisive Transactions.

(a)            If the  Participant's  Separation  from  Employment is because of
               Disability  or  death,  the  right  of  the  Participant  or  his
               successor in interest to exercise an Option shall  terminate  not
               later than five years after the date of such Disability or death,
               but in no  event  later  than 15 years  from  the date of  grant;
               provided, however, that if such Participant is eligible to retire
               with  the  ability  to  begin  immediately  receiving  retirement
               benefits under the Company's pension plan at or after age 55, his
               or his successor in interest's right to exercise Options shall be
               determined as if his  Separation  from  Employment was because of
               Retirement.

(b)            If the  Participant's  Separation  from  Employment is because of
               Retirement,  the right of the  Participant  to exercise an Option
               shall terminate not later than 15 years from the date of grant.

(c)            Unless the Committee  deems it necessary in  individual  cases to
               extend  a  Participant's  exercise  period,  if  a  Participant's
               Separation   from   Employment  is  for  any  reason  other  than
               Retirement,  Disability or death, the right of the Participant to
               exercise an Option  shall  terminate  not later than 30 days from
               the date of Separation from Employment but in no event later than
               15 years after the date of grant.

(d)            At the time of his  Separation  from  Employment  for any  reason
               other than Cause,  a  Participant  shall vest in a portion of any
               Option  granted  that he has held for less than one year from the
               date of the  grant.  The  portion  of such  Options  in which the
               Participants  shall vest shall be determined by  multiplying  all
               shares  subject to such Options by a fraction,  the  numerator of
               which  shall be the  number of  Completed  Months  of  employment
               following the date of grant and the denominator of which shall be
               twelve.

(e)            A Participant  who vests in any Options under  subsection (d) may
               not  exercise  such  Options  prior  to the  satisfaction  of the
               one-year holding  requirement and the Exercisability  Requirement
               pertaining to such Options.  Any Options vested under  subsection
               (d)  must be  exercised  within  one  year  from  the date of the
               Participant's Separation from Employment.

(f)            If  the  Participant's  employer  is a  Subsidiary  involved  in
               a  Divisive  Transaction,  or  if  the  Participant's  employment
               is  terminated  with the  consent  of the  Company  (as a result
               of a    business  transaction  or a  reduction  in  force or any
               other  circumstances  approved  by the  Committee),  the right of
               the  Participant  or his  successor  in interest to exercise an
               Option   shall  terminate  not less than  three  years  after the
               date of the  closing  of such  Divisive  Transaction,  or if a
               Participant's  employment is terminated  with the consent of the
               Company,  but in no  event  later  than 15  years  from  the date
               of  grant;  provided,  however,  if such Participant  is eligible
               to retire with the ability to begin  immediately  receiving
               retirement benefits  under  the  Company's  pension  plan at or
               after  age  55,  his or his  successor  in  interest's  right to
               exercise  any  Option  shall be  determined  as if he had
               separated from  employment, and such Separation  from  Employment
               was because of  Retirement.  Notwithstanding      anything to the
               contrary in this subsection,  a Participant may not exercise such
               Options prior  to  satisfaction  of the  one  year  holding
               requirement  and  the  Exercisability  Requirement pertaining  to
               such  Options.  In the event of a Divisive Transaction, employees
               of  Sea-Land  Service,  Inc., hired by that corporation  prior to
               January 1, 1986,    shall   be deemed  eligible  to   retire upon
               termination of employment  after age 50 with 20 years of service
               and eligibility to   begin   immediately   receiving   retirement
               benefits under the Company's  defined benefit pension       plan.

(g)            Notwithstanding  anything to the  contrary in the Plan,  if a
               Participant  or former  Participant (i) becomes associated  with,
               recruits or solicits  customers or other employees of the Company
               or   its  Subsidiaries  for, is employed by, renders services to,
               or owns any interest in (other than any nonsubstantial  interest,
               as  determined  by  the  Committee)  any   business  that  is  in
               competition with the Company or one of its subsidiaries,  (ii)
               has his employment  terminated by   the  Company or one of its
               Subsidiaries  for Cause or on account of actions by the
               Participant which are detrimental to the interests of the Company
               or its subsidiaries,  or (iii) engages in,   or has engaged in,
               conduct at the time of or subsequent to the  termination  of his
               employment with the Company or its Subsidiaries which the
               Committee  determines to be  detrimental to the  interests of the
               Company or its  subsidiaries then the Committee  may, in its sole
               discretion, except following a Change of Control, terminate any
               Options held by the Participant,  regardless   of whether then
               exercisable.

9.      Options Non-assignable and Non-transferable.

        Any  Option  granted  under  this  Plan  shall  be  non-assignable   and
non-transferable  other than as provided in Section 10 and shall be  exercisable
during the  Participant's  lifetime only by the Participant who is the holder of
the Option or by his guardian or legal representative.

10.     Death of Option Holder.

        In the event of the death of a Participant who is an Option holder under
the Plan while  employed by the Company or a Subsidiary or prior to the exercise
of all rights under an Option,  the Option  theretofore  may be exercised by the
Participant's  Beneficiary or, if no Beneficiary is designated,  by the executor
or  executrix  of the  Participant's  estate or by the person or persons to whom
rights  under  the  Option  shall  pass  by  will or the  laws  of  descent  and
distribution in accordance with the provisions of the Plan and of the Option and
to the same extent as though the Participant were then living.

11.     Withholding Tax.

        Whenever the Company proposes or is required to issue or transfer shares
of Company  Stock under the Plan,  a  Participant  shall remit to the Company an
amount sufficient to satisfy any federal,  state or local income and payroll tax
withholding  liability  prior to the delivery of any certificate or certificates
for such shares.  Alternatively,  in the sole discretion of the Company,  to the
extent permitted by applicable laws including regulations  promulgated under the
Exchange Act, such  federal,  state or local income and payroll tax  withholding
liability  may  be  satisfied  prior  to the  delivery  of  any  certificate  or
certificates for the shares by an adjustment,  equal in value to such liability,
in the number of shares to be transferred to the Participant. Whenever under the
Plan payments are to be made in cash,  such  payments  shall be net of an amount
sufficient  to  satisfy  any  federal,  state or local  income and  payroll  tax
withholding liability.

12.     Effective Date of the Plan.

        This Plan is effective on September 12, 1990.

13.     Termination, Modification.

(a)            Prior to a Change of Control, the Board, on the recommendation of
               the  Committee,  may  terminate the Plan or may amend the Plan in
               such respects as it shall deem  advisable.  Following a Change of
               Control,  this Plan may not be terminated or amended  without the
               approval  of the  Benefits  Trust  Committee.  A  termination  or
               amendment  of the Plan  shall  not,  without  the  consent of the
               Participant,  affect a Participant's rights under any Stock Award
               previously granted to him.

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

(c)            Prior to a Change of Control,  an affiliated  corporation's board
               of directors may, with the approval of the  Committee,  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.

14.     Change in Capital Structure or Change in Control.

        (a)    If the number of outstanding shares of Company Stock is increased
               or decreased as a result of a   subdivision or  consolidation  of
               shares,  the payment of a stock dividend,  stock split, or any
               other  change in  capitalization  effected  without  receipt  of
               consideration  by the  Company   (including,  but not limited to,
               the creation or issuance to  shareholders  generally of rights,
               options or warrants for the purchase of common or preferred
               stock of the  Company),  the number   and kind of shares of stock
               or securities of the Company to be subject to the Plan,  the
               maximum  number of shares  or  securities which may be  delivered
               under the Plan,  and other  relevant    provisions  shall be
               appropriately  adjusted by the  Committee,  whose  determination
               shall be  binding and conclusive on all persons.

        (b)    If the Company is a party to a consolidation or a merger in which
               the Company is not the surviving corporation,  a transaction that
               results in the acquisition of substantially  all of the Company's
               outstanding  stock by a single  person  or  entity,  or a sale or
               transfer  of  substantially  all of  the  Company's  assets,  the
               Committee  may,  subject to the  approval of the  Benefits  Trust
               Committee,  take such actions with respect to  outstanding  Stock
               Awards as the Committee deems appropriate.

        (c)    Notwithstanding  anything  in  the  Plan  to  the  contrary,  the
               Committee  may,  subject to the  approval of the  Benefits  Trust
               Committee,  take the foregoing actions without the consent of any
               Participant and the Committee's determination shall be conclusive
               and binding on all persons for all purposes.

        (d)    Notwithstanding any provisions of this Plan to the contrary, upon
               the  occurrence  of  (i)  a  Change  of  Control  as  defined  in
               subsection  (e),   below,   and  subject  to  an  election  under
               subsection (f), below, the three (3) year holding  requirement of
               the Stock  Premium for  deferred  ICP shall be deemed  satisfied;
               (ii)  a  Divisive   Transaction,   the  three  (3)  year  holding
               requirement of the Stock Premium for deferred ICP shall be deemed
               satisfied.

        (e)    As used in this Plan, a "Change of Control" means:

               (i)    Stock  Acquisition.  The  acquisition  by any  individual,

                      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

                             the  Outstanding   Company  Common  Stock  and
                             Outstanding   Company  Voting  Securities, as the
                             case may be;

                             Combination)   beneficially  owns,  directly  or
                             indirectly, 20% or more of, respectively,  the then

                             then  outstanding   voting  securities  of  such
                             corporation  except  to the  extent  that  such
                             ownership  existed  prior  to the     Business
                             Combination; and

                      (C)    at least a majority  of the members of the board of

                             were members of the Incumbent  Board at the time of
                             the execution of the initial  agreement,  or of the
                             action of the  Board  providing  for such  Business
                             Combination; or

               (iv)   Regulated   Business   Combination.    Approval   by   the
                      shareholders of the Company of a Business Combination that
                      is subject, as a matter of law or contract, to approval by
                      the STB (a "Regulated Business  Combination")  unless such
                      Business  Combination  complies  with clauses (A), (B) and
                      (C) of subsection (iii) of this Section 9(e); or

               (v)    Liquidation or  Dissolution.  Approval by the shareholders
                      ---------------------------
                      of the Company of a complete liquidation or dissolution of
                      the Company or its principal Subsidiary.

        (f)    Each  Participant who has elected to defer the payment of an ICP
               award pursuant to Section 5(e),  may elect in a time and manner
               determined by the 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 currently  deferred,  and to be
               deferred,  under the Plan determined and payable under the terms
               of the 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  Committee,  but in no event later than ninety
               (90) days  after  becoming a  Participant,  to have  amounts and
               benefits currently deferred,  and to be  deferred, under the Plan
               determined and payable under the terms of the 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.

        (g)    Upon a Change of Control, the Company shall, as soon as possible,
               but in no event more than seven (7) days following a Change of
               Control,  make an irrevocable  contribution to the Trust in
               an amount that is sufficient to pay each  Participant  or
               beneficiary of this Plan the unfunded portion of the benefits to
               which Participants of this Plan or their  beneficiaries are
               entitled, and for which the  Company is liable  pursuant to the
               terms of this Plan as of the date on which  the Change of Control
               occurred.  The amount of the Company's  irrevocable  contribution
               shall be  based on the  accounting  for the most recent  calendar
               year or more recent period for the Plan,  as approved by the
               independent actuary or accountant engaged by the Company prior to
               the Change  of Control and  approved by the Benefits  Trust
               Committee, if selected or changed following a Change  of  Control
               (the "Actuary"),  and shall include  an amount  deemed  necessary
               to pay  estimated  administrative  expenses  for the  following
               five  (5)  years.  The  Benefits  Trust    Committee  shall cause
               such  accounting to be updated, using  participant  data supplied
               to the    Actuary by the Company,  through a date no earlier than
               the date of the initial contribution and notify the Company of
               the amount of additional contributions required as soon as
               possible.

15.     Administration of the Plan.

        Prior to a Change of  Control,  the Plan  shall be  administered  by the
Committee  appointed  from  time to time by the  Board to  administer  the Plan.
Subject  to  paragraph  (e)  below  the  "Committee"  shall be the  Compensation
Committee  unless the Board shall appoint  another  committee to administer  the
Plan.  The Committee  shall have general  authority to impose any  limitation or
condition  upon a Stock Award the  Committee  deems  appropriate  to achieve the
objectives of the award and the Plan,  and in addition,  and without  limitation
and in  addition  to powers  set forth  elsewhere  in the Plan,  shall  have the
following specific authority:

        (a)    The Committee shall have the power and complete discretion (i) to
               delegate  to any  individual,  or to  any  group  of  individuals
               employed by the Company or any Subsidiary thereof,  the authority
               to grant Stock Awards  under the Plan and (ii) to  determine  the
               terms and  limitations of any delegation of authority,  including
               but not  limited to the maximum  Fair  Market  Value of any Stock
               Award  granted  pursuant  to such  delegation,  provided  that no
               individual  Stock  Award  granted  by  an  individual  or  entity
               operating under authority delegated by the Committee may exceed a
               Fair Market Value of $50,000  ($100,000  after December 10, 1997)
               on Date of Grant.

        (b)    The  Committee,  or other individual  or entity  operating  under
               authority delegated  by the Committee and to the extent permitted
               by the terms of such delegation,  shall have the power and
               complete  discretion to determine (i) which eligible officers or
               employees shall receive a Stock  Award, (ii) the number of shares
               of Company Stock to be awarded,  (iii) the time or times when a
               Stock Award shall be granted, (iv) whether a Stock Award shall be
               subject to  restrictions  and   when or upon such other terms the
               restrictions  shall lapse,  and  (v) whether  arrangements to
               discharge a  Participant's  tax obligations  are  satisfactory
               and, if not, to have the Company retain from the shares of Common
               Stock  granted  that number of shares  necessary to satisfy the
               Participant's tax liabilities arising from the Stock Award.

        (c)    The  Committee may adopt rules and  regulations  for carrying out
               the Plan. The interpretation and construction of any provision of
               the Plan by the  Committee  shall be final  and  conclusive.  The
               Committee  may consult  with  counsel,  who may be counsel to the
               Company,  and shall not incur any  liability for any action taken
               in good faith in reliance upon the advice of counsel.

        (d)    The  Board  from  time to time  may  appoint  members  previously
               appointed  and  may  fill  vacancies,   however  caused,  in  the
               Committee.  No  member  of the  Committee  shall be  eligible  to
               participate  in the Plan or in any other  plan of the  Company or
               any  Parent  or   Subsidiary   of  the  Company   that   entitles
               participants   to   acquire   stock,   stock   options  or  stock
               appreciation rights of the Company or any Parent or Subsidiary of
               the Company,  if as a result of such  eligibility he or she would
               cease  to be a  "disinterested  person"  under  Rule  16b-3  with
               respect to the Plan.

        (e)    Following a Change of Control,  the Benefits Trust  Committee may
               remove  and/or  replace the Plan's  administrator.  Additionally,
               following  a  Change  of  Control,  any  and  all  final  benefit
               determinations for Participants,  their beneficiaries,  heirs and
               assigns and decisions  regarding  benefit  claims under this Plan
               shall rest with the Benefits  Trust  Committee or its delegate in
               its sole judgment and absolute discretion.

16.     Notice.

        All notices and other  communications  required or permitted to be given
under this Plan shall be in writing  and shall be deemed to have been duly given
if delivered  personally or mailed first class,  postage prepaid, as follows (a)
if to the Company - at its  principal  business  address to the attention of the
Secretary;  (b) if to any  Participant - at the last address of the  Participant
known to the sender at the time the notice or other communication is sent.

17.     Construction.

        The Plan shall be governed by the laws of the Commonwealth of Virginia.

Addendum.

        Addendum I

        "Pursuant  to  Sections  4a  and 8 of  the  Plan,  with  respect  to any
Non-Qualified  Stock  Option  ("NQSO")  granted  to any  Participant  who may be
subject to taxation in The Netherlands at any time during the term of such NQSO,
the Committee  shall have the authority to impose  additional  conditions on the
exercise of the NQSO.

        "Effective  for any NQSO granted after  December 31, 1997, the Committee
may, in  addition to any other  conditions  specified  in the option  agreement,
require that the NQSO is granted  conditionally.  Such conditions  shall include
that the NQSO can be  exercised  only  with the  approval  of the  Participant's
Senior Vice  President - Human  Resources  ("SVP-HR").  Such  approval  shall be
granted  at the  discretion  of the  SVP-HR,  which  shall  not be  unreasonably
refused.  Approval  may be refused for  reasons  which shall be set forth in the
option agreement such as, but not limited to, the following:  (i) termination of
employment  for willful or gross  misconduct or receipt of notice of termination
for  such  conduct;  (ii)  disclosure  of  confidential  information;  or  (iii)
rendering  services  to a  competitor.  Once  approval  has been  obtained,  the
Participant must immediately exercise the NQSO. If approval is refused or if the
NQSO is not  exercised  immediately  upon  receipt  of  approval,  it  shall  be
forfeited.
