of, and Switching and Yard Services for, all trains  (including  Operator Trains
and CRC Trains) over the Shared Assets (other than Operator's Facilities, unless
requested to do so by the Operator  thereof) without any  discrimination  at any
time in favor of or against  either  Operator,  but in  accordance  with written
policies and  priorities  for  categories of freight,  type of Railcar,  size of
train  and  train  destinations  established  from  time to time by the  General
Manager and  approved by the CRC Board to achieve  the  maximum  efficiency  and

non-discrimination, written policies and priorities applicable to the control of
such functions by CRC at other locations included within the Shared Assets Area.

               (k) Railcar Weighing. All Railcars for the account of an Operator
which  originate or terminate on Shared Assets and which require  weighing shall
be weighed by and at the  expense of such  Operator or its  customer,  and at no
cost to CRC.

               (l) Freight Claims. The Operators shall agree among themselves on
the  most  fair,   practical  and  efficient   arrangements   for  handling  and
administering  freight  loss and damage  claims  with the  intent  that (i) each
Operator  shall be  responsible  for losses  occurring  to lading  either in its
possession  or in the  possession of CRC for the account of such  Operator,  and
(ii) the Operators shall follow relevant AAR rules and formulas in providing for
the allocation of losses which are either of undetermined  origin or in Railcars
handled in interline service by or for the account of both Operators.

               (m) Freight Car Repairs. If any Railcars are bad ordered while on
the Shared  Assets and must be set out from a CRC Train or Operator  Train,  CRC
shall  promptly  return such  Railcars to the  Operator  in whose  account  such
Railcars  reside in  accordance  with such  Operator's  instructions.  CRC shall
furnish, at such Operator's expense, required labor and material to perform, and
shall perform,  light repairs on such bad ordered  Railcars as necessary to make
such Railcars legal and safe for movement.  CRC shall bill such Operator for the
costs of such light repairs in accordance  with the Field and Office  Manuals of
the AAR Interchange Rules in effect at the time such repairs are performed.  CRC
shall bill  directly to and collect  from the  applicable  Operator  charges for
repair items that, under the AAR Interchange  Rules, are the  responsibility  of
the Railcar  owner and/or the handling line  carriers.  Each Operator may rebill
charges for repair items that are the responsibility of the Railcar owner and/or
the handling line carriers. If any such bad ordered Railcar cannot be made legal

                                     - 14 -


and safe for movement by the  performance of light repairs,  CRC shall,  at such
Operator's  expense,  arrange for appropriate removal of the affected Railcar in
accordance with such Operator's instructions.

               (n) Train  Services.  Actual  costs  incurred  by CRC to  provide
special services (other than services  otherwise provided for in this Agreement)
at the request of an Operator with respect to trains,  locomotives  and Railcars
for the  account  of such  Operator,  shall  be  paid by such  Operator  to CRC,
provided that the costs and terms of similar special  services  rendered to each
Operator shall be without discrimination between Operators as to cost and terms,
giving due allowance to any differences in the costs of providing such services.

               (o) Wrecking Service.  Wrecking service or wrecking train service
required in connection  with services  contemplated  by this Agreement  shall be
provided by CRC (or its designee) as promptly as possible.

               (p)  Admission  of  Third  Parties.   Notwithstanding  any  other
provision in this Agreement,  no party may permit any Person (other than a party
hereto) to have  access to,  operate  over or use any Shared  Asset  without the
prior  approval of all  parties,  which  approval may be given or refused in the
sole discretion of each party.

               Section 4     Equipment and Properties.

               (a)  Procurement.  CRC shall  procure,  operate and  maintain all
equipment,  real property rights and  improvements  thereon which are reasonably
required  for (i) CRC to operate the Shared  Assets,  and (ii) the  Operators to
move  trains  over the  Shared  Assets,  in each  case in  accordance  with this
Agreement.

               (b)  Contribution  of Locomotives by Operators.  Upon  reasonable
request by the General  Manager,  the Operators  shall  furnish to CRC,  through
full-service  lease or other  mutually  satisfactory  arrangements,  locomotives
reasonably  required by CRC for the  performance of its  obligations  under this
Agreement.   The  respective  obligations  of  each  Operator  to  furnish  such
locomotives  shall  be  based,  insofar  as  reasonably  practicable,  upon  the
Operator's CRC Train Usage  Percentage  during the calendar month preceding such
request for the Shared Assets Area or Zone in which such  locomotives are needed
by CRC. It is the parties' intention that (i) the arrangements pursuant to which
such  locomotives  are  furnished by either  Operator to CRC shall  provide that
heavy  maintenance,  repair and  overhaul  shall be the  responsibility  of such
Operator,  (ii) locomotives furnished by either Operator to CRC may, in order to
permit  maintenance,  repair and overhaul of such locomotive units, be exchanged
for other locomotive units furnished by such Operator,  and (iii) the respective

                                     - 15 -


obligations  of each  Operator to furnish such  locomotives  upon request by the
General Manager shall be adjusted on at least a monthly or more frequent basis.

               (c)  Locomotive  Service  and  Repairs.  At  the  request  of  an
Operator,  CRC shall furnish  required labor and material to perform,  and shall
perform,  fueling and servicing of any Operator's  locomotive,  as well as light
repairs on any Operator's  locomotive as necessary to make such locomotive legal
and safe for  movement.  CRC shall bill such  Operator  (or other  owner of such
locomotive)  for the  costs of such  fueling,  servicing  and light  repairs  in
accordance with industry  practice in effect at the time such fueling,  services
or  repairs  are  performed.  If any such  locomotive  cannot  be made  safe for
movement by the performance of light repairs,  CRC shall, at the expense of such
Operator (or other owner of such locomotive), arrange for appropriate removal of
such locomotive in accordance with such Operator's instructions.

               Section 5     Maintenance.

               (a)    Routine Maintenance.

                      (i)    CRC  shall be responsible  for Routine  Maintenance
        when  necessary or  desirable  to maintain  the Shared  Assets in a safe
        operating condition, and to permit and facilitate (A) the performance by
        CRC of its obligations  pursuant to this  Agreement,  and (B) the use of
        Shared Assets by the Operators in accordance with this Agreement.

                      (ii)   CSXT or NSR,  directly or through their  respective
        affiliates,  may perform the work which CRC performed  prior to the date
        of this  Agreement  when (A) CRC does not possess the skills  needed for
        such work,  (B) CRC lacks the  necessary  employees to do such work in a
        timely fashion,  or (C) CRC does not possess the equipment  needed to do
        such  work.  CRC and the  party  performing  the work  shall  agree to a
        reasonable fee for such work prior to performance. CRC, CSXT and NSR may
        agree to have  additional  work  performed  either by CSXT, NSR or their
        affiliates.

               (b)    CRC Program Maintenance.

                      (i)    The General Manager shall prepare and submit to the
        CRC Board a Program Maintenance plan concurrently with the submission of
        an Operating Budget and the Capital Expenditure Budget to the CRC Board.

                                     - 16 -


                      (ii)   Any  of CRC,  CSXT or NSR may at any time deliver a
        Program Maintenance Proposal to the other two of them and to the General
        Manager and each member of the CRC Board.

                      (iii)  The  CRC Board shall  either (A) approve any or all
        of such Program  Maintenance  Proposals and plan with such changes as it
        deems  appropriate,  include  the costs  thereof in a pending or amended
        Capital  Expenditure Budget, and direct the General Manager to cause the
        maintenance  described in approved Program Maintenance Proposals or plan
        to be performed in  accordance  with  Sections  5(b)(iv) and (v), or (B)
        disapprove any or all of such Program Maintenance Proposals or plan.

                      (iv)   Program  Maintenance shall be the responsibility of
        CSXT and NSR  pursuant to contracts  or  arrangements  with CRC, and CRC
        shall not perform Program  Maintenance,  except for Program  Maintenance
        which can be provided by Persons  other than CSXT or NSR at a lower cost
        to CRC than the CSXT or NSR cost thereof.

                      (v)    CRC   shall   select,   to  perform   each  Program
        Maintenance  project  or  program,  the  Operator  which CRC  reasonably
        determines will perform such project or program at the least cost to CRC
        consistent with safe and efficient  operations,  and taking into account
        scheduling considerations,  based on written proposals submitted by each
        Operator.

               (c) Maintenance Standards. Unless otherwise authorized by the CRC
Board,  the General  Manager shall prepare and submit to the CRC Board proposals
(including the Program  Maintenance plan submitted pursuant to Section 5(b)) for
the  performance  of such  Routine  Maintenance  and Program  Maintenance  as is
reasonably  necessary to keep and maintain the Shared  Assets  substantially  in
their condition as of the date of this Agreement.  If the CRC Board fails either
to approve or disapprove by majority vote any such proposal within 45 days after
it was submitted to the CRC Board, the  disagreement  over the propriety or need
for any of the  Routine  Maintenance  or Program  Maintenance  included  in such
proposal  may  be  submitted  by  either  Operator  for  resolution  by  binding
arbitration pursuant to Section 13.

               Section 6     Capital Improvements. Except as provided in Section
5, all capital  improvements  involving  Shared  Assets shall be governed by the
following provisions:

               (a)  Proposed  Projects.  Either  Operator,  CRC or  the  General
Manager  may  propose  to the CRC Board  from time to time  capital  improvement

                                     - 17 -



projects.  Each such  project  shall be  reviewed  by the CRC  Board,  which may
approve or disapprove by majority vote, or fail to approve, such projects.

               (b)  CRC  Board  Approved   Projects.   Each  Operator  shall  be
responsible for an equal share of the initial  budgeted  funding of each capital
improvement  project which has been approved by the CRC Board and is included in
an approved Capital  Expenditure  Budget,  except as provided in Section 6(c). A
final  accounting  shall be made to adjust the initial  budgeted  funding to the
actual project cost as specified in the Accounting Plan.

               (c)    Nonseverable Improvement Projects.

                      (i)    At the written request of an Operator  delivered to
        the other,  each Operator shall,  within 45 days of the delivery of such
        request, submit to an arbitrator in accordance with Section 13 a written
        proposal with respect to a  Nonseverable  Improvement  project which was
        neither  approved  nor  disapproved  by  majority  vote by the CRC Board
        within 45 days  after such  project  was  proposed  to the CRC Board (A)
        describing  any  changes  which such  Operator  proposes be made to such
        project and specifying a schedule,  budget and  allocations  between the
        Operators of initial capital costs of such Nonseverable Improvement,  or
        (B) proposing that it not be made.

                      (ii)   The  arbitrator receiving the proposals referred to
        in Section  6(c)(i) (A) shall consider (1) the degree,  if any, to which
        the  construction,  operation and use of such  Nonseverable  Improvement
        would impair or interfere with the use of Shared Assets by CRC or either
        Operator,  or conflict with any pending capital improvements included in
        an  approved  Capital   Expenditure  Budget,  and  (2)  the  budget  and
        allocations  between  the  Operators  of initial  capital  costs of such
        Nonseverable  Improvement  as proposed by each  Operator,  and (B) shall
        determine  within 45 days of such receipt which of such proposals  shall
        be implemented, or that such Nonseverable Improvement shall not be made,
        and the CRC Board  shall  approve  any  proposal  which such  arbitrator
        determines shall be implemented.

               (d)    Severable Improvement Projects.

                      (i)    Each  Operator shall have the  unilateral  right to
        construct and exclusively fund any Severable  Improvement  which was not
        approved by the CRC Board.

                      (ii)     Each Severable  Improvement funded exclusively by
        an Operator shall be used  exclusively by that Operator,  which shall be
        solely responsible for maintaining such Severable Improvement at its own
        expense,  until such time that the other  Operator  gives written notice
        that it desires  also to use such  Severable  Improvement,  stating  the
        amount  which such other  Operator is  prepared  to pay to the  Operator

                                     - 18 -


        which initially  funded such Severable  Improvement for the right to use
        such Severable Improvement.

                      (iii)  If  the Operators are unable to agree on the amount
        of such payment  within 45 days after the notice  referred to in Section
        6(d)(ii) was given, then at the written request of an Operator delivered
        to the other  after 45 days but  before 60 days  after  such  notice was
        given,  each  Operator  shall,  within 15 days of the  delivery  of such
        request, submit to an arbitrator in accordance with Section 13 a written
        statement setting forth the proposed payment by the second Operator, and
        the arbitrator  shall within 45 days of such receipt  determine which of
        such  proposed  amounts  shall  apply,  which  shall be  binding on both
        Operators and paid promptly.

                      (iv)    Such   Severable   Improvement   shall   become  a
        Nonseverable  Improvement  at the time  such  second  Operator  pays the
        amount so  determined  and,  thereafter,  maintenance  and  other  costs
        associated with the operation of such  improvement  shall be apportioned
        between the Operators as provided in this Agreement.

               (e) Capital  Improvements as Shared Assets. Upon completion,  all
capital improvements approved by the CRC Board and all Nonseverable Improvements
shall become part of the Shared Assets owned by CRC subject to all provisions of
this Agreement, free and clear of all Operator liens.

               (f) Title to Severable  Improvements.  Each Operator shall retain
title to all Severable Improvements  exclusively funded by such Operator. At any
time  during the term of this  Agreement,  an  Operator  may remove (at its sole
expense) any Severable  Improvement which it exclusively  funded,  provided that
such  Operator has  repaired (at its sole  expense) any damage to a Shared Asset
caused by such removal and has restored the related Shared Assets  substantially
to their  condition at the time such  Severable  Improvements  were made. In the
event an Operator shall not have removed any Severable  Improvement to which the
Operator  shall  have  title  prior to the  expiration  or  termination  of this
Agreement, title to such Severable Improvement shall vest in CRC, free and clear
of all Operator liens, upon such expiration or termination.

               (g)  Noninterference.  The  construction,  operation  and  use of
Severable Improvements by an Operator shall not impair or interfere with the use
of  Shared  Assets  by  CRC or the  other  Operator,  nor  shall  any  Severable
Improvement  conflict  with any  pending  capital  improvements  included  in an
approved Capital Expenditure Budget.

                                     - 19 -



               (h) Switch  Connections.  CRC shall,  upon the written request of
one or both Operators,  provide for switch and turnout  connections  from Shared
Asset tracks to a private  sidetrack owned by a shipper or other Person, if such
request:

                       (i)   includes   the commitment of the  Operator or  both
Operators making such request, or

                      (ii)   is  accompanied by a  written undertaking from such
shipper or other Person,

in each case  satisfactory to CRC, to pay to CRC all costs incurred from time to
time by CRC to provide for such switch and  turnout  connections  within 30 days
after it delivers a bill for such costs to such Operator,  Operators, shipper or
other Person.

               (i)    Adjacent Improvements.

                      (i)    In  the event an Operator  constructs,  acquires or
        funds the cost of an Adjacent  Improvement (whether or not such Adjacent
        Improvement is ultimately  owned by such  Operator),  the other Operator
        shall be entitled to share usage of such Adjacent  Improvement by giving
        written  notice stating the amount which such other Operator is prepared
        to pay to the first Operator for such right. If the Operators are unable
        to agree on the amount of such payment  within 45 days after such notice
        was given,  then at the written request of an Operator  delivered to the
        other after 45 days but before 60 days after such notice was given,  the
        matter shall be submitted for resolution by binding arbitration pursuant
        to Section 13 and the  provisions  of Section  6(d)(iii)  shall apply to
        determine the amount of such payment.

                      (ii)   After  the  second  Operator  pays  the  amount  so
        determined, if the first Operator owns or has a property interest in the
        Adjacent Improvement,  the provisions of this Section 6 shall be applied
        as if such improvement were a Nonseverable Improvement.  If a shipper or
        another  Person  unrelated  to the first  Operator  owns  such  Adjacent
        Improvement,  the second  Operator  shall be entitled to share fully the
        rights  of  the  first   Operator  in  connection   with  such  Adjacent
        Improvement in consideration of the initial payment.

               (j)  Operator's  Facilities.  The  foregoing  provisions  of this
Section 6 shall not apply to any capital improvement (including, but not limited
to, a transloading facility or automotive ramp) within an Operator's Facility.

               Section 7     Accounting.

to the Shared Assets Area shall be readily  identifiable by distinct  accounting
codes.

               (b) Financial Statements.  CRC shall deliver to each Operator (i)
within 30 days after the end of each calendar month, a summary income  statement
and a summary  balance sheet showing as of the last day of and for such calendar
month, major categories of CRC revenue,  expense,  assets and liabilities,  (ii)

statements  described  in Rule  10-01 of  Regulation  S-X under  the  Securities
Exchange Act of 1934, as amended,  as modified by the Accounting Plan, and (iii)
within 30 days after the last day of each CRC fiscal year,  statements of income
and cash flow and a balance  sheet as of and for the  fiscal  year ended on such
day,  prepared  in  accordance  with  GAAP  and the  USOA,  as  modified  by the
Accounting Plan.

               Section 8     Costs and Budgets.

               (a) CRC Costs.  CRC shall pay (and,  except for  Excluded  Taxes,
CSXT and NSR shall,  pursuant to Section 9,  reimburse CRC for) all of the costs
and expenses to maintain its  ownership of the Shared  Assets and to operate and
maintain  the  Shared  Assets,  including  but  not  limited  to all  Taxes  and
assessments,   licenses,  permits  and  any  other  governmental  authorizations
required to own,  operate and maintain the Shared  Assets,  the principal of and

all other costs of its capital.

               (b) Employee Cost Reimbursement. CRC shall reimburse CSXT and NSR
for the wages,  pro rata portion of fringe  benefits,  other  direct  employment
costs (including additives) and other actual  employee-related costs of any CSXT
or NSR employee, respectively, who provides Temporary Services.

               (c)    Capital Expenditure Budget.

                      (i)    The  General  Manager  shall  prepare and submit to
        each member of the CRC Board at least 30 days prior to the  beginning of
        each CRC fiscal year, a Capital Expenditure Budget for such fiscal year,
        specifying for such year the schedule of Program  Maintenance and Shared
        Asset  capital  improvements  to be performed  and  constructed  for the
        benefit of both Operators during such fiscal year and the months therein
        during which such expenditures are proposed to be made, for approval, or
        modification and approval, by the CRC Board.

                                     - 21 -



                      (ii)   The  General  Manager  shall not permit any capital
        expenditure to be made by CRC, CSXT or NSR except in accordance with the
        Capital  Expenditure  Budget  in  effect  from  time to time,  Severable
        Improvements  exclusively  funded by an Operator and  emergency  capital
        expenditures made (A) to preserve,  or to mitigate a serious  diminution
        in, the value and  usefulness of a Shared Asset to CRC, CSXT and NSR, or
        (B) to prevent or mitigate a serious disruption in the operation and use
        of the Shared Assets by or for CRC, CSXT or NSR.

                      (iii)  Any  Capital Expenditure  Budget may be  amended in
        writing at any time by the CRC Board.

               (d)    Operating Budget.

                      (i)    The  General  Manager  shall  prepare and submit to
        each member of the CRC Board at least 30 days prior to the  beginning of
        each  fiscal  year of CRC,  an  Operating  Budget for such  fiscal  year
        showing  the budget  amounts of  revenues  and  expenses  for each month
        during such fiscal year, for approval,  or modification and approval, by
        the CRC Board.

                      (ii)   The   General  Manager  shall  use  all  reasonable
        efforts to prevent  CRC  expenses  with  respect to Shared  Assets for a
        period from exceeding the amounts shown on the Operating Budget for such
        period.

                      (iii)  The  General  Manager  shall  give  prompt  written
        notice to each member of the CRC Board of any actual or, in the judgment
        of the  General  Manager,  probable,  material  change in the  revenues,
        expenses or working capital  requirements  shown on the Operating Budget
        for any period.

                      (iv)   Any  Operating Budget  may be amended in writing at
        any time by the CRC Board.

               Section 9     Cost Sharing.

               (a)  Accounting  Plan.  The parties shall develop and implement a
written plan of  accounting  containing a detailed  description,  by category of
cost and location,  of the costs associated with the management and operation of

        CRC  within  the  Shared  Assets  Area or each Zone with  respect to CRC

        functions related to the Shared Assets Area shall be apportioned between
        the Operators on the basis of the CRC Train Usage Percentages;

                      (v)    Dispatching  and train  control  costs  (including,
        without  limitation,   labor,   equipment,   materials  and  maintenance
        expenses)  incurred by CRC with respect to the Shared  Assets Area shall
        be apportioned between the Operators on the basis of the CRC Train Usage
        Percentages;

                      (vi)   Police and other costs incurred by CRC with respect
        to security  within the Shared Assets Area shall be apportioned  between

        for the period to which such Taxes relate; and

                      (x)    Insurance  costs  incurred  by CRC with  respect to

                                     - 23 -


        apportioned between the Operators on the basis of the Operator's Expense
        Percentages for the period to which such insurance costs relate;

If the parties are unable to agree on the terms and provisions of the Accounting
Plan,  such  disagreement  may be submitted by either Operator for resolution by
binding arbitration pursuant to Section 13.

               (b) Usage Statement.  CRC shall deliver to each Operator prior to
the last day of each calendar month, a written  statement  showing for the prior
Billing Month:

                      (i)    the  total  number of loaded and empty  Railcars in
        the account of each Operator in CRC Trains which performed Switching and
        Yard Services or operated  directly between customer  facilities in each
        Zone;

                      (ii)   the total number of loaded and empty Railcars moved
        by or for such Operator in Operator  Trains which  operated  overhead or
        directly  to  Jointly-Operated  Facilities,   Operators'  Facilities  or

first or last Railcar of such train is on Shared Assets and (B) each time that a
Railcar is  removed  from or added to a train in the  Shared  Assets  Area shall
constitute a separate movement of such Railcar.

               (c) Expense  Statement.  Concurrently  with the  delivery of each
Usage Statement to the Operators, CRC shall deliver to the Operators a statement
showing (i) the expenses incurred by CRC to own, operate and maintain the Shared

accordance with GAAP and the USOA, as modified by the Accounting Plan.

               (d) Capital Expenditure Statement. Concurrently with the delivery
of each Usage  Statement to the Operators,  CRC shall deliver to the Operators a

                                     - 24 -



               (e) Bills.  Concurrently  with the delivery to the Operators of a
Usage  Statement for a Billing Month,  CRC shall deliver to each Operator a bill
(a "Bill") showing for such Billing Month:

                      (i)    one hundred and two percent (102%) of the amount of
        each Reimbursable  Expense apportioned to such Operator for such Billing
        Month under the Accounting Plan;

                      (ii)   one-twelfth of  fifty  percent (50%) of the  annual
        amount of Budgeted Capital Expenditures approved by the CRC Board; and

                      (iii)  one-twelfth of the  Interest Rental  apportioned to
        such Operator.

               (f) Payment.  Each Operator  shall pay to CRC the amount shown on
each Bill as being payable by such Operator, on or before the 30th day after the
date of such Bill  regardless  of  whether  or not such  Operator  disputes  the
accuracy of any amount or calculation shown on such Bill.

               (g)    Disputed Bills.

                      (i)    Any  dispute by an Operator of the  accuracy of any
        amount or calculation shown on any Bill shall be described and specified
        in reasonable  detail in a Dispute  Letter from such Operator to CRC and
        the other Operator within two years after the date of such Bill.

                      (ii)   Any amounts or calculations shown on any Bill which
        are not disputed in accordance with Section  9(g)(i) shall  conclusively
        be deemed to be accurate and shall be binding on each Operator and CRC.

                      (iii)  CRC and both Operators  shall promptly  endeavor to
        resolve the disputes  described in each Dispute Letter, and if they fail
        to agree to a resolution of such disputes within 60 days of the delivery
        of such  Dispute  Letter  to CRC,  then the firm of  independent  public
        accountants  which has been engaged as auditors for CRC shall be engaged
        to  resolve  such  disputes  in  accordance  with GAAP and the USOA,  as
        modified by the  Accounting  Plan,  and the written  resolution  of such
        disputes  signed  by such  accounting  firm  shall  be  binding  on each
        Operator and CRC.

                      (iv)   Any  adjustments  to Bills  which  result  from the
        resolution of Dispute  Letter  disputes shall be reflected as charges or
        credits on the first Bills  delivered by CRC to the Operators after such
        disputes have been resolved.


                                     - 25 -



                      (v)    The  fees in connection  with the resolution of any
        Dispute Letter disputes of the accounting firm which has been engaged as
        auditor  for CRC  shall be paid  fifty  percent  (50%) by CSXT and fifty
        percent (50%) by NSR.

               Section  10    Access.  CRC shall  give to each  Operator  during
normal CRC  Administrative  Office  business  hours,  access to inspect and make
copies of any and all books of record and accounts  relating to this  Agreement,
all of which shall be maintained by CRC at the CRC Administrative Office.

               Section 11    Liability.  Except as otherwise provided in Section
3(l) (Freight Claims), Section 11(f) (Specified Level Damages) and Section 11(g)
(Substance Abuse Exceptions), the responsibility between and among CRC, CSXT and
NSR for all Damage arising out of, incidental to or occurring in connection with
this Agreement shall be apportioned without consideration of fault or negligence
of any kind or  degree  in  accordance  with the  remaining  provisions  of this
Section 11. The  provisions of this Section 11 are intended to inure only to the
benefit of the parties hereto and their corporate successors and affiliates, and
not to create any benefits for any third parties.

               (a) Operators' Sole Responsibility.  Except as otherwise provided
in Section 11(f)  (Specified  Level Damages) and Section 11(g)  (Substance Abuse
Exceptions),  each Operator shall assume and bear all  responsibility for Damage
to its own trains,  locomotives  and  equipment,  to Railcars  and lading in its
possession  or being  handled  for its account and for the death of or injury to
its own employees.

               (b)    Operators' Joint Responsibility.

                      (i)    Train  Usage.  Except as otherwise  provided in (1)
        Section  11(b)(ii)  (First  Year),  (2) Section 11(a)  (Operators'  Sole
        Responsibility),  (3) Section  11(c)(i)  (CRC  Damages  Generally),  (4)
        Section 11(c)(ii)(B) (No Reallocation for Insurance),  (5) Section 11(f)
        (Specified  Level  Damages),  and (6)  Section  11(g)  (Substance  Abuse
        Exceptions), and subject to Section 11(c)(ii)(A) (Net of Insurance), all
        Damage shall be apportioned between the Operators in proportion to their
        respective  Total  Train  Usage  Percentages  in the Zone in  which  the
        incident  giving rise to such Damage  occurred for the 12 calendar month
        period immediately preceding the incident giving rise to such Damage.

                      (ii)   First  Year.  If an incident  giving rise to Damage
        for which the Operators are jointly  responsible  under Section 11(b)(i)
        (Train Usage) occurs before June 1, 2000, responsibility for such Damage
        shall be borne  equally by the  Operators,  with each  being  liable for
        one-half (1/2) of the damages.

               (c)    CRC Responsibility - Allocation and Insurance.

                      (i)    CRC Damages Generally. Except as otherwise provided
        in this Section 11(c), all Damages incurred by CRC,  including,  without
        limitation,  those  Damages  apportioned  to  CRC  under  Section  11(f)
        (Specified  Level Damages) shall be CRC expenses,  allocated as provided
        in Section  11(b)  (Operators'  Joint  Responsibility),  and included in
        Expense Statements charged to the Operators.

                      (ii)   (A)    Net of Insurance.

                                    (1)  Notwithstanding  any other provision in
                      this  Agreement (but subject to Section  11(c)(ii)(B)  (No
                      Reallocation  for  Insurance)),   all  Damages  (including
                      without limitation,  loss or destruction of, or damage to,
                      CRC's own property)  charged to the  Operators,  under the
                      Expense  Statements or otherwise,  shall be net of any CRC
                      insurance.  It is the intent of the parties (a) for CRC to
                      look  first  to any  insurance  proceeds  available  to it
                      before  attempting  to recover any such  Damages  from the
                      Operators  and (b) for the  Operators'  obligation to make
                      direct  payment to CRC not to include  any  obligation  to
                      make direct  payment for any Damages  covered by insurance
                      procured by or on behalf of CRC.

                                    (2)  If and to  the  extent  that  CRC is an
                      insured under,  or otherwise  provided  coverage under, an
                      insurance  policy  or  policies  each  of  which  provides
                      coverage  for both CRC and one  Operator but not the other
                      Operator,  and  regardless of whether two or more of these
                      policies   shall  be  in  existence   or  have   different
                      deductible-retention  amounts  and/or  limits of recovery,
                      then the amount of insurance  proceeds deemed  "available"
                      under  Section  11(c)(ii)(A)(1)  to which CRC  shall  look
                      before  either  Operator  shall  have any  obligation  for
                      direct payment shall, as to each Operator,  be the maximum
                      available  limit of the insurance  providing  coverage for
                      both that Operator and CRC.

                             (B) No Reallocation for Insurance. When part of the
               apportioned  Damage will be  satisfied  from  insurance  coverage
               under this Section 11(c), and part paid directly by the Operator,
               the insured  portion of the Damage shall be apportioned  among or
               between CRC and the Operators (and consequently  between or among
               their  insurers)  in the same manner and amounts as it would have
               been  apportioned  if the loss were not net of insurance.  If any
               such allocation  results in one party hereto  suffering a greater
               uninsured loss than the other(s) because of differing deductibles

                                     - 27 -


               or  self-retentions,  that  difference in coverage shall not be a
               basis for any reapportionment or reallocation of Damage.

               (d) Process.  Each Operator shall be responsible for the payment,
handling,  administration  and  disposition  of all  Damage  for  which it bears
exclusive  responsibility under Section 11(a) (Operators' Sole  Responsibility),
and both Operators shall have joint  responsibility  for the payment,  handling,
administration  and  disposition  of all  Damage  for  which  they  are  jointly
responsible under Section 11(b) (Operators'  Joint  Responsibility)  and Section
11(c) (CRC  Responsibility  - Allocation  and  Insurance).  In  assigning  joint
responsibility  to both  Operators,  it is not the intent of this Agreement that
the  Operators  will actually act jointly,  but rather that the  Operators  will
agree between  themselves on the most practical and efficient  arrangements  for
handling,  administering,  and  disposing  of Damage  for which  they bear joint
responsibility,  with the objective of  eliminating  unnecessary  duplication of
effort and minimizing overall costs.

               (e)  Indemnification.  Each party to this Agreement covenants and
agrees to (i) fully  indemnify  and save  harmless  the  other  parties  to this
Agreement  from and against any payments  which are the  responsibility  of such
party under this  Agreement,  and all expenses,  including  attorneys'  fees and
expenses and other expenses of any court or regulatory  proceeding,  incurred by
such  other  parties  in  defending  any  claim  that they are  liable  for such
payments,  and (ii) defend such other  parties  against such claims with counsel
selected by such party and reasonably acceptable to such other parties.

               (f)    Specified Level Damages.

                      (i)    Damages  Amount.  Section  11(a)  (Operators'  Sole
        Responsibility)  and Section  11(b)  (Operators'  Joint  Responsibility)
        shall apply directly only when the total amount of all Damages resulting
        from a  single  incident  is $25  million  or less.  Responsibility  for
        Damages  resulting  from a single  incident for which Damages exceed $25
        million shall be allocated as stated in this Section 11(f)(i).

                             (A.1) Tier One  Damages  Defined.  In this  Section
               11(f),  "Tier One Damages" for any incident  occurring during and
               between June 1, 1999 and May 31, 2000 shall,  except as otherwise
               provided in Section 11(g) (Substance Abuse  Exceptions),  include
               the greater of:

                                    (1)     $25 million of Damages; or

                                    (2) the lowest amount of Damages which, when
                      allocated  among all parties,  results in an allocation to
                      either  Operator  of  Damages  in an  amount  equal to all
                      insurance  benefits available to that Operator (called the

                                     - 28 -


                      "Lesser  Insured  Operator")  which  has  the  lesser  (as
                      between  the  Operators)  amount  of  insurance   benefits
                      available to it, including, without limitation,  insurance
                      to which CRC looks under Section 11(c) (CRC Responsibility
                      - Allocation  and  Insurance).  In  determining  insurance
                      benefits  available to the Lesser Insured  Operator,  both
                      property and liability  insurance  shall be considered but
                      (I) only to the extent benefits are actually  available in
                      connection  with  that  incident  and (II)  they  shall be
                      calculated  separately (i.e.,  property insurance benefits
                      shall not be considered in any  determination of available
                      liability insurance benefits and vice versa).

               In this  Section  11(f),  "Tier  One  Damages"  for any  incident
               occurring  on or after June 1, 2000  shall,  except as  otherwise
               provided in Section 11(g) (Substance Abuse  Exceptions),  include
               only the first $25 million of Damages  incurred  by the  parties,
               unless otherwise agreed by the parties.

                             (A.2)  Allocation  of   Tier One Damages.  Tier One
               Damages shall be allocated among the parties as follows:

                                    (1) Any Damage for which each Operator would
                      otherwise  be  solely   responsible  under  Section  11(a)
                      (Operators'  Sole  Responsibility)  shall be  allocated as
                      provided in Section 11(a);

                                    (2) Any and all CRC Damages other than those
                      specified    in   preceding    Section    11(f)(i)(A.2)(1)
                      (including,  without  limitation,  Damage  to its  trains,
                      locomotives  and  equipment,  whether owned or leased,  to
                      Railcars and lading in its possession or being handled for
                      its account, and to the property of any others, as well as
                      any Damage arising from or in connection with the death of
                      or injury to any persons,  including,  without limitation,
                      its own employees) shall be allocated and paid as provided
                      in Section  11(c) (CRC  Responsibility  -  Allocation  and
                      Insurance); and

                                    (3) Any  and  all  other  Damages  shall  be
                      allocated as provided in Section 11(b)  (Operators'  Joint
                      Responsibility).

                             (B.1) Tier Two  Damages  Defined.  In this  Section
               11(f),  "Tier  Two  Damages"  shall  include  (1)  those  Damages
               allocated  to Tier  Two  under  Section  11(g)  (Substance  Abuse
               Exceptions)  and  (2)  all of  those  Damages  in  excess  of the
               aggregate   Tier   One   Damages    calculated    under   Section
               11(f)(i)(A.1).

                                     - 29 -




                             (B.2)  Allocation  of Tier  Two  Damages.  Tier Two
               Damages shall be allocated between or among the parties hereto in
               proportion to their respective fault or negligence in causing the
               Damage.

                      (ii)   Dispute  Resolution.  Any dispute  between or among
        the parties hereto in determining  their  respective fault or negligence
        in  causing  the  Damage  or  otherwise  relating  to  their  respective
        responsibilities  for Damage arising out of,  incidental to or occurring
        in connection  with any incident  shall be submitted  for  resolution by
        binding arbitration pursuant to Section 13 (Arbitration).

                      (iii)  Amendment  of  Certain  Amounts.  The  $25  million
        amount  referred to in this  Section  11(f) may be  adjusted  every five
        years  following the date of this  Agreement  with the prior approval of
        all  parties,  which  approval  may be  given  or  refused  in the  sole
        discretion of each party.

               (g) Substance  Abuse  Exceptions.  Each Operator shall assume and
bear all  responsibility for Damage to the extent caused by acts or omissions of
any of its employees while under the influence of drugs or alcohol, and Sections
11(b)  (Operators'  Joint  Responsibility)  and Section 11(f)  (Specified  Level
Damages)  shall not apply to any such Damage.  If, but for the operation of this
Section  11(g),  all or any Damages from an incident  would  otherwise have been
Tier One Damages under Section 11(f) (Specified  Level Damages),  the portion of
the Damages caused by acts or omissions of any the  employee(s)  while under the
influence of drugs or alcohol  shall be Tier Two Damages,  and  allocated  under
Section  11(f)(i)(B.2)  (Allocation  of Tier  Two  Damages),  and the  remaining
portion of the Damages from that  incident  shall be included in, and  allocated
under,  Tier One or Tier Two  under  the  otherwise  applicable  provisions  for
Section 11(f)(i).

               (h)  Transaction  Agreement.   Section  2.8  of  the  Transaction
Agreement  shall control any conflict  between  Sections  11(b) and (c) and said
Section 2.8.

               (i)  Damages.   As  used  in  this  Section  11  only,  the  term
"Damage(s)" shall exclude:

                      (i)    Operator   Consequential  Damages (which are always
        borne by the Operator which sustained them); and

                      (ii)   any  claim by any party, in its own right,  against
        any  other  party  for  exemplary  or  punitive  damages,  but  not  for
        allocation  under  this  Section 11 of  exemplary  or  punitive  damages
        claimed against that party by a third person not a party hereto.


                                     - 30 -



With regard to exemplary and punitive Damages the parties  acknowledge and agree
that, with regard to the subject of this Agreement,  the intent and agreement of
the parties is that no party shall bring or recover any claim for  exemplary  or
punitive damages, in its own right,  against any other party, but that any party
will allocate, in accordance with this Section 11, exemplary or punitive Damages
from any claim against it by a third person not a party hereto.

               Section 12    No Partnership.  Nothing in this Agreement shall be
construed to establish a partnership or joint venture between or among CRC, CSXT
or NSR or any of their affiliates or associates.

               Section 13    Arbitration.  Any dispute, controversy or claim (or
any  failure  by the  parties  to agree on a matter as to which  this  Agreement
expressly or implicitly contemplates subsequent agreement by the parties, except
for matters left to the sole  discretion of a party)  arising out of or relating
to this  Agreement,  or the breach,  termination  or validity  hereof,  shall be
finally settled through binding arbitration by a sole,  disinterested arbitrator
in accordance with the Commercial  Arbitration Rules of the American Arbitration
Association. The arbitrator shall be jointly selected by the parties but, if the
parties  do  not  agree  on an  arbitrator  within  30  days  after  demand  for
arbitration  is made by a party,  they  shall  request  that the  arbitrator  be
designated by the American Arbitration Association.  The award of the arbitrator
shall be final,  binding  and  conclusive  upon the  parties.  Each party to the
arbitration  shall pay the  compensation,  costs,  fees and  expenses of its own
witnesses,  experts and counsel.  The compensation and any costs and expenses of
the arbitrator shall be borne equally by the parties.  The arbitrator shall have
the power to  require  the  performance  of acts  found to be  required  by this
Agreement,  and to require the cessation or  nonperformance  of acts found to be
prohibited by this Agreement.  The arbitrator  shall not have the power to award
consequential  or punitive  damages.  Judgment  upon the award  rendered  may be
entered  in any  court  having  jurisdiction  thereof,  which  court  may  award
appropriate  relief at law or in equity.  All  proceedings  relating to any such
arbitration, and all testimony, written submissions and award, of the arbitrator
therein,  shall be private and confidential as among the parties,  and shall not
be  disclosed  to any other  Person,  except as  required  by law and  except as
reasonably  necessary to  prosecute  or defend any  judicial  action to enforce,
vacate or modify such arbitration award.

               Section  14    Term.  This Agreement shall become effective as of
the date first above  written and shall remain in effect until the  twenty-fifth
(25th)  anniversary of such date,  subject to the right of CSXT and NSR to agree
prior  to the  twenty-third  (23rd)  anniversary  of such  date to  extend  this
Agreement for a renewal period of five (5) years;  and if so extended,  to agree
prior to the  twenty-eighth  (28th)  anniversary  of such date to further extend
this  Agreement  for an additional  renewal  period of five (5) years (each such
period, a "Renewal Term").


                                     - 31 -



               Section 15    Force Majeure. The obligations,  other than payment
obligations,  of the parties to this Agreement shall be subject to force majeure
(which shall include strikes, riots, floods,  accidents,  Acts of God, and other
causes or  circumstances  beyond the  control of the party  claiming  such force
majeure  as an  excuse  for  non-performance),  but only as long as,  and to the
extent that, such force majeure shall prevent performance of such obligations.

               Section 16. Entire Agreement.  This Agreement and the Transaction
Agreement,   including  the  other  Ancillary  Agreements  (as  defined  in  the
Transaction  Agreement)  constitute the entire agreement and supersede all other
prior  agreements and  understandings,  both written and oral, among the parties
with respect to the subject matter  hereof,  except the letter  agreement  dated
April 8, 1997  between  CSX and NSC to the  extent  such  April 8,  1997  letter
agreement  covers matters not addressed or amended hereby or in the  Transaction
Agreement or the Ancillary Agreements (as defined in the Transaction Agreement);
provided  that it is the intent of the parties that this  Agreement  shall be an
effectuation of such April 8, 1997 letter  agreement  consistent with its terms,
and that the provisions of this Agreement shall be interpreted to give effect to
such April 8, 1997 letter agreement;  and provided further that, in the event of
any  inconsistency  between the terms of this  Agreement  and such April 8, 1997
letter agreement, this Agreement shall prevail.

               Section   17    Amendment  and  Waiver.  Any  amendment  to  this
Agreement  must be in writing and executed and  delivered by CRC,  CSXT and NSR,
subject to any  jurisdiction  of the STB. Any waiver of any term or provision of
this  Agreement  must be in writing  and  executed  and  delivered  by the party
entitled to enforcement of such term or provision.

               Section 18    Severability.  If any term, provision,  covenant or
restriction  of this Agreement is held by a court of competent  jurisdiction  or
other  authority to be invalid,  void,  unenforceable  or against its regulatory
policy,  such provision is intended to be  ineffective  only to the most limited
extent  possible in such  context and the  remainder  of the terms,  provisions,
covenants  and  restrictions  of this  Agreement  shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

               Section 19    Remedies.

               (a) Entitlement to Certain Remedies.  Each party acknowledges and
agrees that the other parties would be  irreparably  damaged in the event any of
the  provisions of this  Agreement  were not performed by it in accordance  with
their specific terms or were otherwise  breached.  It is accordingly agreed that
each party shall be entitled to an injunction or injunctions to prevent breaches
of such provisions and to specifically  enforce such provisions,  in addition to
any other remedy to which such party may be entitled, at law or in equity.

                                     - 32 -



               (b) Preclusion of Certain  Remedies.  In no event shall any party
be liable to the other  parties  for any  consequential,  indirect,  incidental,
punitive or other similar  damages  including,  but not limited to, lost profits
for any breach or default,  or any act or omission  arising out of or in any way
relating  to this  Agreement,  under any form or  theory  of action  whatsoever,
whether in contract,  tort or otherwise.  The foregoing is not intended to alter
or limit the allocation of responsibility for Damage as provided in Section 11.

               Section 20    Interpretation.  This Agreement was drafted jointly
by CSXT and NSR, each of which was advised by its own counsel and other advisors
concerning all of the terms and provisions  hereof;  accordingly,  any ambiguity
herein should not be construed in favor of or against any of them.

               Section 21.  Headings.  Headings of  Sections and   paragraphs in
this  Agreement are for  reference purposes only and shall not affect in any way
the   meaning or   interpretation of  any term  or provision of  this Agreement.

               Section 22    Parties.  This Agreement shall inure to the benefit
of and be binding  upon CRC,  CSXT and NSR and any  successor  of any of them by
operation of law, and any assignee  agreed to by them in accordance with Section
23, and nothing in this  Agreement is intended or shall be construed to give any
other Person any legal or equitable right, remedy or claim under or with respect
to this Agreement or any term or provision hereof.

               Section 23.  Assignment.

               (a) Limitation. Except as provided in Section 23(b), neither this
Agreement  (including the documents and instruments  referred to herein) nor any
of the rights,  interests  or  obligations  hereunder,  shall be assigned by any
party,  including by operation of law,  without the prior written consent of the
other parties (except to a controlled subsidiary), which consent may be given or
refused in the sole discretion of each party.

               (b) Successor. Any party without the consent of the other parties
may assign all of its rights and  obligations  under this  Agreement only to any
successor in the event of a merger, consolidation,  sale of all or substantially
all its assets  (but only if such sale  includes  all routes and lines  owned by
such party to access the Shared Assets),  if such assignee executes and delivers
to the other parties  hereto an agreement  reasonably  satisfactory  in form and
substance  to such other party under which such  assignee,  which is  reasonably
satisfactory to the other party, assumes and agrees to perform and discharge all
the obligations and liabilities of the assigning  party;  provided that any such

                                     - 33 -


assignment  shall not  relieve  the  assigning  party from the  performance  and
discharge of such obligations and liabilities.

               Section 24. Notices.  Any notice given by CRC, CSXT or NSR to the
others  under  this  Agreement  shall be  deemed  delivered  on the date sent by
registered  mail,  or by such  other  means  as they  may  agree,  and  shall be

to be executed in counterparts by their duly authorized  officials as of the day
first above written.

                               OPERATING PROTOCOLS


                          Consolidated Rail Corporation
                               Shared Assets Area
                          Terminal Capacity Guidelines


Yard Operations

o   Cars  loaded or empty moving  outbound to either parent* company, which have
    been  made up  for train   departure at either a  serving  merchandise yard,
    Automotive  Terminal or jointly used  Intermodal Facility will be considered
    available at the published departure time for scheduled trains and the later
    of 4 hours after   notice to the parent or actual  available time (set time)
    for non-scheduled or extra trains.  Cars  remaining available for  departure
    in excess of ten (10) hours will be subject to a charge of $141.00  per car.
    Thereafter, for every  eight (8) hours that the same cars continue to remain
    on track, along  with all   other cars of the   same block codes  within the
    originating   dispatch yard, will  be subject  to an   additional  charge of
    $141.00 per car.

o   Cars loaded or empty  assembled for outbound train dispatch to either parent
    company will be considered  available at published  departure  time for such
    scheduled  trains.  The Shared Assets Areas management will provide four (4)
    hours  advance  notice  prior to set time on  non-scheduled  or extra trains
    before they will be considered available for departure.

o   Management  of Shared  Assets Areas may refuse an inbound  train of the same
    category when a specific destination terminal has been holding more than one
    (1)  intermodal,  automotive,  manifest  or unit train of a parent for power
    and/or crew beyond ten (10) hours of scheduled departure or availability and
    conditions within the involved  destination  terminal preclude the effective
    handling of the offered inbound trains.

o   Acts  of God,  Mainline  blockages,  labor  strikes  or  other  causes  to a
    cessation of consistent  service beyond the control of a parent company will
    be  considered  by the  management  of the  Shared  Assets  Areas  as to the
    legitimacy of any assessment.

o       Opportunities for the Shared Assets Areas management to consolidate

- ---------------------
*The term "parent" means CSXT and/or Norfolk Southern Railway Co. ("NSR") and is
not intended to describe the legal relationship between the parties.




                                        1





     trains for the  benefit of a  specific  Shared Assets  Area  operation  and
     the involved parent,  as mutually agreed by the parties, will not result in
     charges on cars designated for the annulled train resulting from said
     consolidation.

o   An  inventory  of hold cars  awaiting  disposition  within any given  Shared
    Assets Area territory  should not exceed thirty (30) cars per day for either
    CSXT or NSR  individually.  The Shared Assets Areas  management may elect to
    limit  receipt  of  inbound  car flow  from the  delinquent  parent  for the
    affected  Shared Assets Areas  territory,  in accordance with the guidelines
    for holding  trains.  Any loaded or empty car including  those in unit train
    consists  carrying a "No Bill" status more than  twenty-four (24) hours will
    be assessed $10.00 per hour in excess thereof.

o   Trains  inbound to the Shared Assets Area territory must have proper car and
    train documents.  If this information is lacking,  the Shared Area managers,
    at their  discretion,  may hold trains  outside the boundaries of the Shared
    Assets Area until proper documentation is received.

o   Regardless of company of  employment,  any qualified crew in the Shared Area
    may operate any  locomotive,  regardless of ownership,  in that area for the
    purposes of positioning/hostling or movement of light power between yards.

Held Trains

o   In recognition  of terminal  fluidity and capacity  utilization,  the Shared
    Assets Areas management can require, in coordination with a parent's command
    center,  an inbound  train to be held  outside  the  boundaries  of a Shared
    Assets Area.

    -     Such  notification  must be given with enough notice for the parent to
          chamber  the  train  at  a  location  that  minimizes   disruption  to
          operations.

    -     Decisions by the Director of Train  Operations  of Shared Assets Areas
          management  are final in this  regard.  Neither  parent may compel the
          Shared Assets Areas management to accept trains.

    -     Similarly, the decision to hold out a train other than temporary holds
          is recognized as a serious  action,  which will be done only after all
          other alternatives are  exhausted.  Data  on  these  actions  will  be
          maintained by Shared  Assets  Areas management  and will be  regularly
          available for briefing  to the  Conrail's  Board of  Directors  at its
          pleasure.






                                        2


Storage

o   Neither  parent  company  may store or  pre-position  cars on Shared  Assets
    Area's  tracks,  including  yard and  industrial  tracks to which  they have
    access.  Empty cars routed to the Shared  Assets  Areas must have a customer
    destination assigned, and must be loaded without beginning to accrue charges
    as described in Conrail's Demurrage Tariff in effect on May 1, 1999. When it
    is determined  that cars cannot be delivered to the customer within 60 hours
    of arrival,  a call will be made to the parent's  operations  center.  After
    such a call is made, except in extraordinary  cases, these cars will then be
    placed on the parent's first available outbound train.

o   CSXT and NS will  independently  establish  such  demurrage  and car storage
    arrangements  with customers as each deems proper.  Should customers keep or
    store cars on SAA tracks  beyond the time at which  charges  would  begin to
    accrue as called for in Conrail's Demurrage Tariff in effect on May 1, 1999,
    then the  parent  road  will be  assessed  $100 per car per day to cover the
    operational  cost of congestion and  inefficient  use of Shared Assets Areas
    facilities.

o   CSXT  and   NSR recognize that  certain customers are currently provided car
    storage  within the   Shared Asset  Areas, and   that this   storage  may be
    essential to the  functioning of the business of these customers.  CSXT, NSR
    and   Shared Assets  will review   current pools and by consent of all three
    parties   approve their makeup and location based on operating efficiencies.
    Thereafter  pools will   be regularly   reviewed for the   provision of such
    storage to avoid congestion.  Any request for additional car storage for any
    Shared   Assets  Area customers  must be approved   by the Parents, who will
    consider  the  availability of  additional space with a view toward assuring
    that   operations in the  Shared Assets   Area remain  fluid and will not be
    affected by providing such car storage.

Interchange

o   CSXT and NSR will not  interchange  cars to each  other  within  the  Shared
    Assets  Areas  locations  unless  specifically   provided  through  separate
    agreements. No open interchanges have been established except at industries.










                                        3



Blocking

o   To ensure the equal and fair use of the Shared  Assets Area  capacity by its
    parent companies, the following car classification requirements will govern:

    -   Each parent  company  will be required to block  inbound  trains for the
        Shared Assets  Areas.  Each parent will make the number of blocks called
        for in the  split-date  Operating  Plan.  Failure to comply with inbound
        blocking  requirements and execute appropriate setoffs (unless otherwise
        directed by Shared Assets
        management)  within the Shared  Assets Area will result in an assessment
        of $50.00 per loaded or empty car.

    -   Management of the Shared Assets Areas will be required to block outbound
        trains.  Parent  companies  will  receive  the  number of blocks at each
        Shared  Assets  Area  terminal  that  is  called  for in the  split-date
        Operating Plan.

    -   Changes to the number of blocks made by or  delivered  to a Shared Asset
        terminal may be made only by mutual consent of all three parties.

    -   Parent companies,  except by joint agreement,  may not compel the Shared
        Assets  Areas  management  to make a  greater  number  of  blocks at any
        terminal,  beyond the number of called for in the  split-date  Operating
        Plan.

    -   Each   parent may  change  the  definition of   its own  specific blocks
        originating at a Shared Assets Area terminal.

Hours of Service and Recrews

o   Train  crews on parent  trains  approaching  a Shared  Assets Area must have
    sufficient  time to  terminate  in or exit the Shared  Assets  Areas  before
    hours-of-service  laws require them to rest.  Sufficient  time is considered
    the trains scheduled elapsed time to terminate in or pass through the Shared
    Assets Area.  The Shared Assets Areas  management  may grant an exception if
    the train can make it to its destination without undue disruption.

o   Shared Assets Areas shall have the option to provide T&E relief  service for
    any road train on the hours-of-service law, regardless of parent company.

    -   Such relief will be provided  after  coordination  with the  appropriate
        parent's  operations  center indicating the involved parent will provide

    -   Recrews  will be at the sole cost and expense of the parent  whose train
        is recrewed at full cost plus a $500 surcharge.

    -   If specific  trains  frequently  require  recrews,  Shared  Assets Areas
        management  may request the parent to change its schedule or slotting of
        subject train with the right to repeatedly  hold that train for a recrew
        outside the Shared  Assets  Areas as set forth  under the "held  trains"
        provision   until  such   appropriate   adjustments   are  made  to  the
        non-conforming schedule.

    -   Data on  trains  recrewed  will be  maintained  by Shared  Assets  Areas
        management  and will be  regularly  available  for briefing to Conrail's
        Board of Directors at its pleasure.

Charges

o   The charges  paid by either  owner under these  protocols  will be made to a

    the three parties (CSXT, NSR, and/or CSAO).  Proposed changes are subject to
    the arbitration  provisions of the Shared Asset Area Operating Agreements in
    the event CSXT and NSR cannot agree.
