                             -----------------------

                 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 retirement plan, hereinafter called the "Special
Plan," is to provide an incentive for corporate officers comprising a select
group of management or highly compensated employees to exert maximum efforts for
the Company's success and to remain in the service of the Company until
retirement.

     2.   The Special Plan as provided herein was originally effective as of
March 1, 1983, and supersedes the Employees' Special Pension Plan of The
Chesapeake and Ohio Railway Company and the Plan for Additional Annuities for
Qualifying Members under the Supplemental Pension Plan of The Baltimore and Ohio
Railroad Company, hereinafter called the "Former Plans."

     3.   The "Company" as used herein means CSX Corporation and such other of
its affiliated corporations as shall adopt this Special Plan with the approval
of the Compensation Committee and by action of their boards of directors for the
benefit of corporate officers who are covered or may become covered by the
Special Plan.

     4.   The term "Compensation Committee" means the Compensation Committee of
the Board of Directors of CSX Corporation (the "Board of Directors").

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

     6.   The Company's "Independent Accountant" means an independent accountant
or actuary engaged by the Company and, if selected or changed following a Change
of Control, approved by the Benefits Trust Committee.

     7.   The incentives under the Special Plan shall consist of special
retirement allowances provided by the Company at retirement to certain
employees, hereinafter referred to as "Participants," who shall participate as
provided herein (eligibility for participation is set forth in Section II).

     8.   "Cause," as to any Participant, means (i) an act or acts of personal
dishonesty of the Participant intended to result in substantial personal
enrichment of the Participant at the expense of the Company or any of its
affiliates; (ii) a violation of the management responsibilities by the
Participant which is demonstrably willful and deliberate on the Participant's
part and which is not remedied in a reasonable period of time after receipt of
written notice from the Participant's employer; or (iii) the conviction of the
Participant of a felony involving moral turpitude.

     9.   "Good Reason," as to any Participant, means (i) the Participant's
compensation or employment related benefits are reduced (other than
across-the-board reductions that affect management employees generally); (ii)
the Participant's status, title(s), office(s), working conditions, or management
responsibilities are diminished (other than changes in reporting or management
responsibilities required by applicable federal or state law); or (iii) the
location of Participant's place of employment is changed by more than 30 miles
without the Participant's consent.

     10.  The Special Plan shall, where appropriate, refer to and have meanings
consistent with all of the relevant terms of any other regularly maintained
pension plan which currently provides or did provide immediately prior to March
1, 1983, retirement benefits for non-contract employees of the Company and is or
was maintained by CSX Corporation or any of its affiliated corporations whose
officers participate in the Special Plan. Such existing regularly

                                        1

<PAGE>

maintained pension plans which provided benefits immediately prior to March 1,
1983 for employees of the Company, and covered periods of service granted in
subsections 4(a) and 4(b) of Section V, or those which may be established
hereafter, as amended from time to time, shall be referred to herein as the
"Pension Plans." Accordingly, regardless of formal differences which may exist
between the Special Plan and the Pension Plans in the use of terminology, the
definitions and principles which are set forth in the Pension Plans with respect
to compensation, average compensation, credited service, and similar terms shall
be applied and construed hereunder in a manner consistent with the purposes of
the Special Plan and the Pension Plans. In any instance in which the male gender
is used herein, it shall also include persons of the female gender in
appropriate circumstances.

Section II - PARTICIPATION
--------------------------

     1.   Every person who was a Participant in the Former Plans as in effect
immediately prior to March 1, 1983, shall continue as a Participant in the
Special Plan on and after such date for the purpose of any applicable provisions
hereof.

     2.   On and after March 1, 1983, Participants shall include any employees
who participate in the Pension Plans and who are entitled to benefits provided
under Section V, Subsection 8 hereof; provided, however, that the only benefit
that such employees shall be eligible to receive under this Special Plan shall
be the benefit provided in accordance with such Subsection unless they are
otherwise entitled to benefits under other provisions of this Special Plan.

     3.   On and after March 1, 1983, additional persons eligible to be
Participants shall be those specified in Section V, Subsection 4(c).

Section III - CREDITABLE SERVICE
--------------------------------

     1.   Creditable service under the Special Plan shall have the same meaning
and apply in the same manner as creditable service under the Pension Plans,
except that it shall also include any additional creditable service which may
have been or which may be granted to a Participant in accordance with the
provisions of Section V, Subsections 3 and 4. Provided, however, notwithstanding
any provisions of the Pension Plans to the contrary, a Participant in the
Special Plan who is in the employ of the Company and who does not receive
compensation in any calendar month due to amounts deferred under the Company's
Deferred Compensation Program, Supplementary Savings and Incentive Award
Deferral Plan, and any other amounts of compensation deferred under any other
arrangement approved by the Compensation Committee nevertheless shall receive
creditable service under the Special Plan.

     2.   Notwithstanding any other provisions of this Special Plan or the
Pensions Plans to the contrary, effective January 1, 1989:

     (a)  Prior to January 1, 1992, a Participant must have been continuously
          employed by the Company for a period of not less than 10 years to
          become entitled upon retirement to receive payment of a special
          retirement allowance from this Special Plan in respect of any
          additional creditable service, pension supplement, pension or benefit
          granted under Section V, Subsections 3(a) or 3(b) of this Special
          Plan. After December 31, 1991, this Subsection (a) shall only apply to
          Section V, Subsection 3(b); and,

     (b)  Prior to January 1, 1992, a Participant must have been continuously
          employed by the Company for a period of not less than 5 years to
          become entitled to receive payment of a special retirement allowance
          from this Special Plan in respect of any additional creditable service
          granted under Section V, Subsection 4(d), of this Special Plan;
          provided, however, a person who has already attained age 60 when he
          first becomes employed by the Company, and who also becomes and
          continuously remains a Participant from his first date of employment
          until attainment of age 65, shall become entitled upon retirement to
          receive payment of a special retirement allowance from this Special
          Plan in respect of any additional creditable service granted under
          Section V, Subsection 4(d) of this Special Plan; and

                                       2

<PAGE>

     (c)  After December 31, 1991, a Participant must have been continuously
          employed by the Company for a period of not less than 10 years and
          must have attained age 55 to become entitled to receive a special
          retirement allowance from this Special Plan in respect to any
          additional creditable service accrued after December 31, 1991, granted
          under Section V, Subsection 4(d), of this Special Plan or a pension or
          benefit granted after December 31, 1991 under Section V, Subsection
          3(a) of this Special Plan; provided, however, a Participant who has at
          least 5 years of continuous service and who dies while actively
          employed shall be entitled to the additional creditable service
          accrued after December 31, 1991; and, provided further, a Participant
          who terminates employment because of a Divisive Transaction or a
          workforce downsizing or with the consent of the Chief Executive
          Officer of CSX Corporation ("Chief Executive Officer") prior to age 55
          with 10 years of continuous service shall be entitled to the
          additional creditable service accrued after December 31, 1991. For
          purposes of this Section III, Subsection 2(c), "Divisive Transaction"
          shall mean a transaction in which the Participant's employer ceases to
          be a subsidiary of CSX Corporation or there is a sale of substantially
          all of the assets of the subsidiary.

     (d)  Prior to a Change of Control, in no event shall a Participant be
          eligible to receive a payment in respect of any benefits granted under
          Section V, Subsections 3(a), 3(b) or 4(d) of this Special Plan before
          such date as the Participant attains the earliest retirement age
          specified in the particular Pension Plan in which the Participant also
          participates, unless an earlier payment from the Special Plan is
          specifically authorized by the Compensation Committee. The
          Compensation Committee shall have full authority and sole discretion
          to interpret and administer the foregoing rules, and any decision made
          by the Compensation Committee shall be final and binding. Following a
          Change of Control, the same rules apply except that the Benefits Trust
          Committee shall have full authority and sole discretion to interpret
          and administer the foregoing rules. Any such decision made by the
          Benefits Trust Committee shall be final and binding.

     (e)  In the event of a Change of Control, as defined in Section XI, the age
          55 and length of service requirements contained in Section III,
          Subsection (2)(c), shall be waived for those Participants who are
          employed by the Company at the time of the Change of Control.

Section IV - COMPENSATION AND AVERAGE COMPENSATION
--------------------------------------------------

     Compensation and average compensation under the Special Plan shall have the
same meanings and apply in the same manner as those terms do under the Pension
Plans, except as provided in Section V, Subsection 3(b); provided, however, that
amounts deferred under the Company's Deferred Compensation Program,
Supplementary Savings and Incentive Award Deferral Plan, and any other amounts
of compensation deferred under any other arrangement approved by the
Compensation Committee shall be included in the determination of compensation
and average compensation; and further provided, that compensation and average
compensation hereunder shall not be limited to the amount of $150,000, or such
other amount as adjusted by regulation, as imposed by Sections 401(a)(17) and
415(d) of the Internal Revenue Code.

Section V - SPECIAL RETIREMENT ALLOWANCES
-----------------------------------------

     1.   All of the provisions, conditions, and requirements set forth in the
Pension Plans with respect to the granting and payment of retirement benefits
thereunder shall be equally applicable to the granting of the special retirement
allowances hereunder to Participants in the Special Plan and to the payment
thereof from the Company's general assets or from the Benefits Assurance Trust.
Except as otherwise may be provided in this Special Plan, whenever a
Participant's rights under the Special 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 special
retirement allowance under the Special Plan shall be paid to a surviving spouse
in conformance with the provisions of the Pension Plans, the final installment
payment hereunder shall be made only to the estate of such surviving spouse and
shall not be otherwise paid, regardless of any different provision for such
payment which may be prescribed in the Pension Plans.

                                       3

<PAGE>

     2.   All special retirement allowances being paid on March 1, 1983, under
the Former Plans as they existed immediately prior to such date shall be
continued and be paid hereunder, and, persons participating under the Former
Plans shall continue to participate hereunder in accordance with the terms and
conditions of the Former Plans and any applicable provisions of this Special
Plan.

     3.   The Compensation Committee, upon the recommendation of the Chief
Executive Officer, may grant to an officer of the Company the following benefits
under the Special Plan:

     (a)  Additional creditable service, pensions or benefits hereunder other
          than as provided in the Pension Plan, in recognition of previous
          service deemed to be of special value to the Company.

     (b)  A pension supplement hereunder in a particular instance as determined
          by the Compensation Committee, to be calculated on the basis of
          specific instructions which may depart only for such purpose from any
          of the terms, conditions or requirements of the Pension Plans,
          notwithstanding the provisions of Section I, Subsection 5, and Section
          V, Subsection 1, hereof.

     4.   The following additional creditable service under the Special Plan
shall be granted by the Company at retirement under the Pension Plans:

     (a)  To those Participants of the "Former Plans," creditable service equal
          to that accrued under Section V, Subsection 4 of The Employees'
          Special Plan of The Chesapeake and Ohio Railway Company or under
          paragraphs 1, 2 and 3 of the Plan for Additional Annuities for
          Qualifying Members Under the Supplemental Pension Plan of the
          Baltimore and Ohio Railroad Company, provided that, effective upon a
          Participant's retirement on or after March 1, 1983, creditable service
          under the Special Plan and Pension Plans shall not exceed 44 years.

     (b)  To those Participants in the Special Plan who are listed in Appendix
          I, and who are also participants in the Pension Plans, additional
          creditable service under the Special Plan will be granted as indicated
          for each individual as shown in Appendix I, provided that additional
          creditable service under the Special Plan and credited service under
          the Pension Plans at retirement shall not exceed 44 years.

     (c)  On and after March 1, 1983, new admissions into the class of persons
          who may become Participants in the Special Plan to receive additional
          creditable service hereunder shall only include participants in the
          Pension Plans who are appointed by the Chief Executive Officer or his
          designee.

     (d)  In addition to the additional creditable service granted to
          Participants under (a) or (b) above, beginning March 1, 1983, one year
          of additional creditable service shall be granted for each year of
          actual service (with allowances for months less than twelve) between
          ages 45 and 65 during which a person is a Participant. Those who
          become qualified as provided in (c) above shall have one year of
          additional credited service granted, beginning no earlier than the
          date they are both a Participant and at least age 45, for each year of
          actual service (with allowances made for months less than twelve)
          during which they remain a Participant, but only up to age 65.
          Additional creditable service granted under the Special Plan shall be
          combined with credited service under the Pension Plan (but only if
          credited service under the Pension Plans does not exceed 44 years), to
          result in total credited service and additional creditable service
          under the Pension Plans and the Special Plan which shall not exceed a
          maximum of 44 years. The position, compensation, and other conditions
          upon which a non-contract employee's participation herein is based
          shall be determined from time to time in the absolute discretion of
          the Compensation Committee. Effective December 31, 1993, there shall
          be no new admissions into the class of persons who may receive
          additional benefits pursuant to this subsection 4(d); provided,
          however, the Chief Executive Officer may, by express agreement, offer
          the additional benefits pursuant to this subsection 4(d) to selected
          individuals.

     (e)  Anything to the contrary notwithstanding, any Participant in the
          Special Plan receiving additional creditable service under this
          Subsection 4, and whose responsibilities and compensation are reduced,

                                       4

<PAGE>

          may, in the discretion of the Compensation Committee or the Chief
          Executive Officer, cease to receive any further additional creditable
          service hereunder.

     (f)  A Participant's accrual of additional creditable service as provided
          herein shall not be subject to termination except as provided in
          subparagraph (e) above, or upon retirement or termination of
          employment.

     (g)  Prior to January 1, 1992, a Participant who receives benefits under a
          Salary Continuance and Long-Term Disability Plan of the Company shall
          continue to accrue additional creditable service hereunder subject to
          the same rules that are applicable in such instances under the Pension
          Plans.

     (h)  It is the intent of this Section V that, for the purpose of the
          Special Plan, the additional creditable service provided hereunder
          when added to credited service under the Pension Plans or otherwise,
          shall not in any case exceed 44 years in the aggregate.

     (i)  To those Participants who become qualified as provided in (a), (b) or
          (c) above, a special retirement allowance shall be payable under the
          Special Plan to such Participants or their surviving spouses equal to
          any amount due under the Pension Plans which is not paid in full under
          the Pension Plans.

     (j)  Notwithstanding the preceding, following a Change of Control, any
          additional service or benefits granted under Article V, Subsection 4
          shall be subject to the approval of the Benefits Trust Committee.

     5.   The Company shall accrue and pay under this Special Plan as an
additional supplemental benefit any annual pension benefits that would have been
payable under the Pension Plans as in effect on September 1, 1974, or
thereafter, if Sections 415(b) and 401(a)(17) of the Internal Revenue Code, and
any other relevant provisions of law that impose limitations or have the effect
of limiting the accrual of benefits under the Pension Plans, had not been
enacted into law, unless such additional supplemental benefit is provided by the
Company through another plan created for that purpose.

     6.   The Company shall accrue reserves to the credit of the Special Plan in
advance to cover the costs of any additional creditable service, pensions or
benefits granted under Subsections 3 and 4 hereof, and such pensions or benefits
or special retirement allowances reflecting such credit shall be paid under the
Special Plan. Where additional creditable service is granted, upon retirement in
accordance with the provisions of the Pension Plans, the Participant shall
receive a special retirement allowance equal to the difference between the
retirement allowance computed under the Pension Plans and the amount which would
be payable if the additional credit granted hereunder had been included with the
actual credited service in the computation of the retirement allowance payable
under the Pension Plans. Where a pension or other benefit is granted to a
Participant, such pension or benefit shall be payable as a special retirement
allowance from the Special Plan.

     7.   Notwithstanding any other provision of this Special 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 Special 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 7, "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

                                       5

<PAGE>

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.

     8.   The Company shall accrue and pay under this Special Plan any annual
pension benefit which otherwise would have been payable under the Pension Plans
but for the Participant's deferral of compensation under the Company's Deferred
Compensation Program, Supplementary Savings and Incentive Award Deferral Plan,
or under any other deferred compensation arrangement approved by the
Compensation Committee.

     9.   The obligations of the Company or any of its affiliated corporations
and the benefit due any Participant, surviving spouse or beneficiary under this
Plan shall be reduced by any amount received in regard thereto under the
Benefits Assurance Trust or any similar trust or other vehicle.

Section VI - FUNDING METHOD
---------------------------

     1.   The benefits provided under the Special Plan shall be financed by the
Company and no contribution shall be required of Participants. The Company shall
accrue reserves on its books as follows:

     (a)  As of March 1, 1983, an amount shall be calculated with respect to the
          Former Plans which shall be the actuarially determined present value
          as of that date of all special retirement allowances payable under the
          Former Plans and, under a schedule approved by the Company's
          Independent Accountant, the reserve previously accrued will be
          adjusted.

     (b)  As of March 1, 1983, the actuarially determined present value as of
          that date of all special retirement allowances payable under Section
          V, Subsection 4(b) shall be calculated and, under a schedule approved
          by the Company's Independent Accountant, a reserve equal to that
          amount established.

     (c)  During the year 1983, there shall be accrued the amount required to
          allow regular interest on the adjusted reserve provided in (a) and (b)
          above. Each year thereafter there shall be accrued the amount required
          to allow regular interest on the average reserves standing to the
          credit of the Special Plan during the preceding year.

     (d)  Each year the reserves shall be adjusted to reflect the payment of
          special retirement allowances during the year.

     (e)  Such additional reserves shall be accrued from time to time as may be
          required in accordance with Section V, Subsections 3 and 4, on account
          of grants thereunder made after March 1, 1983.

     (f)  There shall be accrued from time to time, as required, additional
          reserves on account of benefits pursuant to Section V, Subsection 6.

     (g)  At such times as the Plan Administrator shall recommend, the reserves
          accrued to the credit of the Special Plan shall be adjusted on the
          basis of actuarial valuations to reflect the experience under the
          Special Plan, or amendments thereto, or changes in the rate of regular
          interest, or any other actuarial assumptions.

     2.   The Company shall provide all funds required for the administration
expenses of the Special Plan.

     3.   The Company has established the CSX Corporation and Affiliated
Companies Benefits Assurance Trust ("Trust"). Except as provided in Section XI,
the Company is not obligated to make any contribution to the Trust.

     4.   The Special Plan is intended to be unfunded for tax purposes and for
purposes of Title I of ERISA. Participants in the Special Plan have the status
of general unsecured creditors of the Company, and the Special Plan constitutes
a mere promise by the participating employer to make benefit payments in the
future.

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

Section VII - ADMINISTRATION OF SPECIAL PLAN
--------------------------------------------

     1.   Prior to a Change of Control, the Plan Administrator for the CSX
Pension Plan shall be responsible for the general administration of the Special
Plan and for carrying out its provisions.

     2.   Following a Change of Control, the Benefits Trust Committee may remove
and/or replace the Plan Administrator as to the Special Plan. Additionally,
following a Change of Control, any and all benefits determinations for
Participants, their beneficiaries, heirs and assigns and decisions regarding
benefit claims under this Special Plan shall rest with the Benefits Trust
Committee or its delegate in its sole and absolute discretion.

Section VIII - MODIFICATION, AMENDMENT AND TERMINATION
------------------------------------------------------

     1.   The Special Plan represents a contractual obligation heretofore
entered into by the Company in consideration of services rendered and to be
rendered by Participants covered under the Special Plan. Prior to a Change of
Control, the Company 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 provisions of this Special
Plan, or to terminate this Special Plan; provided, however, prior to December 1,
1991, no modification or amendment shall be made to this Special Plan unless
there have been modifications or amendments to correlative provisions of the
Pension Plans, and any modifications or amendments to this Special Plan shall
coincide with the modifications or amendments of the Pension Plans (except
nonconforming revisions to administrative provisions shall be permitted); and
provided, further, that this Special Plan shall only be terminated if the
Pension Plans are terminated, subject to the following limitations:

     (a)  In the event any modification or amendment adversely affects the
          benefits to be received by a retired Participant and the designated
          surviving spouse of a retired Participant, they shall be entitled to
          receive for life the special retirement allowance they would have
          received had the Special Plan not been modified or amended, and each
          designated surviving spouse of a retired Participant shall become
          entitled to receive for life the special retirement allowance that
          such designated surviving spouse would have received had the Special
          Plan not been modified or amended.

     (b)  In the event of the termination of this Special Plan, each retired
          Participant and designated surviving spouse of a retired Participant
          shall be entitled to receive for life the special retirement allowance
          they would have received had the Special Plan not been terminated, and
          each designated surviving spouse of a retired Participant shall become
          entitled to receive for life the special retirement allowance that
          such designated surviving spouse would have received had the Special
          Plan not been terminated.

     (c)  In the event any modification or amendment adversely affects the
          benefit which an active Participant would have been entitled to
          receive if such amendment or modification had not been made, such
          active Participant shall, so long as he remains in the active service
          of the Company, only continue to accrue creditable service and
          benefits prospectively in accordance with the provisions of the
          Special Plan as so modified or amended, unless the Participant shall
          earlier cease to receive any additional creditable service as provided
          in Section V, Subsection 4(e).

     (d)  In the event this Special Plan is terminated, each active Participant,
          in consideration of his continued service to the Company until the
          date of his termination from active employment by retirement or
          otherwise, shall be entitled to retain his accrued additional service,
          or pension or benefits as granted hereunder to such Participant, in
          accordance with the provisions of this Special Plan in effect on the
          day prior to the date of termination, unless the Participant shall
          earlier cease to receive any additional creditable service as provided
          in Section V, Subsection 4(e).

     (e)  In lieu of paying special retirement allowances in accordance with the
          foregoing provisions, the Plan Administrator, at its election, may
          direct the discharge of all obligations to retired Participants,

                                        7

<PAGE>

          designated spouses of retired Participants, and active Participants by
          cash payments of equivalent actuarial value or through the provision
          of immediate or deferred annuities or other periodic payments of
          equivalent actuarial value, as it shall in its sole discretion
          determine, provided that following a Change of Control, the authority
          to make such decisions shall rest solely with the Benefits Trust
          Committee.

     2.   Following a Change of Control, this Special Plan may not be amended or
terminated without the approval of the Benefits Trust Committee.

Section IX - NON-ALIENATION OF BENEFITS
---------------------------------------

     1.   No benefit under the Special Plan shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or
charge, and any attempt to do so shall be void, except as specifically provided
in the Special Plan, nor shall any benefit be in any manner liable for or
subject to the debt, contracts, liabilities, engagements, or torts of the person
entitled to such benefit; and in the event that the Plan Administrator shall
find that any active or retired Participant or designated spouse or spouse under
the Special 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 Special Plan, except as specifically provided in the
Special Plan, then such benefits shall cease to accrue and shall be determined,
and in that event, the Plan Administrator shall hold or apply the same to or for
the benefit of such active or retired Participant or spouse, in such manner as
the Plan Administrator may deem proper.

     2.   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 X - MISCELLANEOUS PROVISIONS
------------------------------------

     1.   Anything in the Special Plan to the contrary notwithstanding, prior to
a Change of Control, if the Plan Administrator finds that any retired
Participant or spouse is engaged in acts detrimental to the Company or is
engaged or employed in any occupation which is in competition with the Company,
and if after due notice such retired Participant or spouse continues to be so
engaged or employed, the Plan Administrator shall suspend the special retirement
allowance 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 special retirement allowance. Furthermore, if the Plan
Administrator finds that any Participant has been discharged for having
performed acts detrimental to the Company, then regardless of any other
provision in the Special Plan, no benefit shall be payable to or on account of
any such Participant's coverage under this Special Plan. Notwithstanding the
preceding, following a Change of Control, the Plan Administrator shall not
implement such action or make such determination without the consent of the
Benefits Trust Committee.

     2.   The establishment of the Special 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 the Company 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 Special Plan.

Section XI - CHANGE OF CONTROL
------------------------------

     1.   If a Change of Control has occurred, the Company shall contribute to
the 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, but calculated with respect to
          the date of the Change of Control, rather than the date of the
          applicable Distribution Event (if different);

     (b)  the present value of accumulated Plan benefits based on the
          assumptions the Company's independent actuary deems reasonable for
          this purpose, as of a Valuation Date, as defined in subsection (7),
          below,

                                       8

<PAGE>

          coinciding with or next preceding the date of Change of Control, to
          the extent such amounts are not already in the Trust. The aggregate
          value of the amount of the lump sum to be contributed to the Trust
          pursuant to this Section XI 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
          who has not yet received a lump sum payment pursuant to subsection
          (2), below, the greater of:

          (i)  the amount such Participant would have received under subsection
               (2), but calculated with respect to the Change of Control, rather
               than the date of the applicable Distribution Event (if
               different), 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 Trust relating to this
               Special Plan does not equal the amount described in the preceding
               sentence, at the time of the valuation, the Company shall make a
               lump sum contribution to the Trust equal to the difference; or

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

     2.   In the event a Distribution Event has occurred, the trustee of the
Benefits Assurance Trust shall, within 45 days of such Distribution Event, pay
to each Participant not making an election under subsection (3), a lump sum
payment equal to the actuarial present value of the aggregate special retirement
allowance each Participant (or any beneficiary of a Participant) has accrued as
of the Valuation Date preceding the date of such Distribution Event pursuant to
the terms of Section V of this Special Plan. 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 on 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 7 of Section V 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.

     For purposes of this Section XI.2, "Participant" includes a former
Participant (i) who resigns within three months after an event constituting Good
Reason or (ii) whose employment was terminated without Cause by the Company or a
participating employer in this Special Plan, in either case upon or after an
event described in Section XI.5(c) or XI.5(d) and prior to the earlier of (x)
the consummation of such event, i.e., actual change in ownership of Outstanding
Corporation Common Stock, Outstanding Corporation Voting Stock (as defined in
Section X.5), and/or assets of CSX Corporation or its principal subsidiary and
(y) a determination by the Board of Directors that such event has been unwound
or reversed or is no longer expected to be consummated.

                                       9

     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 Distribution Event, if earlier, to have amounts and benefits
determined and payable under the terms of this Special Plan as if a Distribution
Event had not occurred. New Participants in the Plan may elect in a time and
manner determined by the Compensation 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 Special Plan as if a Distribution Event 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 Distribution Event shall be invalid.

     4.   Notwithstanding anything in this Special Plan to the contrary, each
Participant who has made an election under subsection (3), above, may elect
within 90 days following a Distribution Event, in a time and manner determined
by the Compensation 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 by the Participant.
Furthermore, as a result of such election, the Participant shall no longer be
eligible to participate or otherwise benefit under the Special Plan. Payments
under this subsection (4) shall be made not later than 7 days following receipt
by the Company of the Participant's election. The Compensation Committee shall,
no later than 7 days after a Distribution Event has occurred, cause written
notification to be given to each Participant eligible to make an election under
this subsection (4), that a Distribution Event has occurred and informing such
Participant of the availability of the election.

     For purposes of this Section XI.4, "Participant" includes a former
Participant (i) who resigns within three months after an event constituting Good
Reason or (ii) whose employment was terminated without Cause by the Company or a
participating employer in this Special Plan, in either case upon or after an
event described in Section XI.5(c) or XI.5(d) and prior to the earlier of (x)
the consummation of such event, i.e., actual change in ownership of Outstanding
                                ----
Corporation Common Stock, Outstanding Corporation Voting Stock (as defined in
Section X.5), and/or assets of CSX Corporation or its principal subsidiary and
(y) a determination by the Board of Directors that such event has been unwound
or reversed or is no longer expected to be consummated.

     5.   As used in this Plan the term "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

          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

          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

          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 individual whose initial
          assumption of office occurs as a result of an actual or threatened

                      Supplemental Retirement Benefit Plan
                 of CSX Corporation and Affiliated Corporations

                      As Amended through February 14, 2001

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

<PAGE>

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.   "Cause," as to any Participant, means (i) an act or acts of personal
dishonesty of the Participant intended to result in substantial personal
enrichment of the Participant at the expense of the Company or any of its
affiliates; (ii) a violation of the management responsibilities by the
Participant which is demonstrably willful and deliberate on the Participant's
part and which is not remedied in a reasonable period of time after receipt of
written notice from the Participant's employer; or (iii) the conviction of the
Participant of a felony involving moral turpitude.

     6.   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.

     7.   "Good Reason," as to any Participant, means (i) the Participant's
compensation or employment related benefits are reduced (other than
across-the-board reductions that affect management employees generally); (ii)
the Participant's status, title(s), office(s), working conditions, or management
responsibilities are diminished (other than changes in reporting or management
responsibilities required by applicable federal or state law); or (iii) the
location of a Participant's place of employment is changed by more than 30 miles
without the Participant's consent.

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

                                       -2-

<PAGE>

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, 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

                                      -3-

<PAGE>

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.

     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.

                                      -4-

<PAGE>

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.

                                      -5-

<PAGE>

     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.

                                      -6-

<PAGE>

     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, but calculated with respect to
          the date of the Change of Control, rather than the date of the
          applicable Distribution Event (if different);

     (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 (7),
          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 who has not yet
          received a lump sum payment pursuant to subsection (2), below, the
          greater of: (i) the amount such Participant would have received under
          subsection (2), but calculated with respect to the date of the Change
          of Control, rather than the date of the applicable Distribution Event
          (if different), had such Participant not made the election under
          subsection (3), below, if applicable; and

          (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

                                      -7-

<PAGE>

               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 Distribution Event has occurred, the trustee of the
Benefits Assurance Trust shall, within 45 days of such Distribution Event, 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 Distribution Event. 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.

     "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.

     For purposes of this Section X.2, "Participant" includes a former
Participant (i) who resigns within three months after an event constituting Good
Reason or (ii) whose employment was terminated without Cause by the Company or a
participating employer in this Supplemental Plan, in either case upon or after
an event described in Section X.5(c) or X.5(d) and prior to the earlier of (x)
the consummation of such event, i.e., actual change in ownership of Outstanding
                                ----
Corporation Common Stock, Outstanding Corporation Voting Stock (as defined in
Section X.5), and/or assets of the Company or its principal subsidiary and (y) a
determination by the Board of Directors that such event has been unwound or
reversed or is no longer expected to be consummated.

     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 Distribution Event, if

                                      -8-

<PAGE>

earlier, to have amounts and benefits determined and payable under the terms of
this Supplemental Plan as if a Distribution Event had not occurred. New
Participants in the Plan may elect in a time and manner determined by the
Compensation Committee, (or, after a Distribution Event, 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 Distribution Event 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 Distribution Event 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 Distribution Event, 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 Distribution Event has occurred, cause written
notification to be given to each Participant eligible to make an election under
this subsection (4), that a Distribution Event has occurred and informing such
Participant of the availability of the election.

     For purposes of this Section X.4, "Participant" includes a former
Participant (i) who resigns within three months after an event constituting Good
Reason or (ii) whose employment was terminated without Cause by the Company or a
participating employer in this Supplemental Plan, in either case upon or after
an event described in Section X.5(c) or X.5(d) and prior to the earlier of (x)
the consummation of such event, i.e., actual change in ownership of Outstanding
                                ----
Corporation Common Stock, Outstanding Corporation Voting Stock (as defined in
Section X.5), and/or assets of the Company or its principal subsidiary and (y) a
determination by the Board of Directors that such event has been unwound or
reversed or is no longer expected to be consummated.

     5.   As used in this Supplemental Plan, 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 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

                                       -9-

<PAGE>

          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
               (including, without limitation, a corporation which as a result
               of such transaction owns the Company or its principal subsidiary
               or all or substantially all of the assets of the Company or its
               principal subsidiary either directly or through one or more
               subsidiaries) in substantially the same proportions as their
