     this  Escrow  Agreement  in  its  performance  hereunder  or in  connection
     herewith,  except to the  extent  such loss,  liability,  damage or expense

     the Escrow Agent exercises its right to apply funds from the Escrow Fund to
     the  payment  of  any  amounts  owing  to  it  hereunder   ("Escrow   Agent
     Receivable")  as a  result  of the  failure  of  one of KCS or TMM to  make
     payment in full of 50% of the Escrow Agent  Receivable in  accordance  with
     Section 11 hereof,  such  non-paying  Party shall promptly  transfer to the
     account  of  the  other  Party  in  accordance   with  such  other  Party's
     instructions  in  immediately  available  funds  an  amount  equal  to  the
     difference  between 50% of the Escrow Agent  Receivable and the amount,  if
     any,  actually paid by the non-paying  Party to the Escrow Agent in respect
     of the  Escrow  Agent  Receivable.  In the  event  that  the  Escrow  Agent
     exercises  its right to apply  funds from the Escrow Fund to the payment of
     the Escrow Agent  Receivable  as a result of the failure of both of KCS and
     TMM to make  payment  in  full of 50% of the  Escrow  Agent  Receivable  in
     accordance  with  Section  11  hereof,  each such  non-paying  Party  shall
     promptly transfer to the account of the other Party in accordance with such
     other Party's  instructions in immediately  available funds an amount equal
     to the  difference  between  50% of the  Escrow  Agent  Receivable  and the
     amount,  if any,  actually paid by the non-paying Party to the Escrow Agent
     in respect of the Escrow Agent Receivable.

     6.   (a) The Escrow Agent may consult legal counsel of its selection in the
     event of any dispute or question as to the meaning or  construction  of any
     of the  provisions of this  Agreement or its duties  hereunder,  including,
     without  limitation,  the validity of any order of any court or arbitration
     tribunal,  and it shall incur no liability and shall be fully  protected in
     acting  or  refraining  from  acting in  accordance  with the  opinion  and
     instructions of such counsel.

          (b) Each of the Parties  acknowledges and agrees that the Escrow Agent
     (i)  shall  not be  deemed  to  have  knowledge  of  the  terms  of,  or be
     responsible  for, any of the  agreements  referred to or  described  herein
     (including,  without limitation,  the Acquisition



     Agreement,  but excluding  this  Agreement) or for  determining  compliance
     therewith  and shall  not  otherwise  be bound  thereby  and (ii)  shall be
     obligated only for the performance of such duties as are  specifically  set
     forth in this  Agreement on its part to be performed and no implied  duties
     or obligations  of any kind shall be read into this  Agreement  against the
     Escrow Agent.

     7. In the event of any  disagreement  between  any of the  Parties  to this
Agreement,  any  adverse  claims or demands  being made in  connection  with the
subject  matter of the escrow,  or in the event that the Escrow  Agent,  in good
faith, is in doubt as to what action it should take hereunder,  the Escrow Agent
may, at its sole option,  refuse to comply with any claims and demands on it and
retain in its possession  without liability to anyone all or any of the property
held by it hereunder,  or refuse to take any other action hereunder,  so long as
such  disagreement  continues or such doubt  exists.  The Escrow Agent shall not
become  liable in any way or to any person for its  failure or refusal to act in
such event,  and the Escrow  Agent shall be entitled to continue to refrain from
acting  until (i) the rights of all  parties  shall have been fully and  finally
adjudicated  by a court of competent  jurisdiction  or  arbitration  tribunal of
competent jurisdiction (and in the case of an arbitration tribunal,  accompanied
by a certificate  signed by an  Appropriate  Officer of KCS and TMM stating that
such  arbitration  was  undertaken  in  accordance  with  Section  12.11  of the
Acquisition  Agreement),  accompanied  by an opinion of counsel that such order,
decree or judgment is final, or (ii) all differences shall have been resolved by
agreement  among all the  interested  persons,  and Escrow Agent shall have been
notified thereof in writing signed by all such persons.  Escrow Agent shall have
the option,  after  thirty (30)  calendar  days  notice to the  Parties,  of its
intention to do so, to file an action in  interpleader  requiring the Parties to

Escrow Agent under this  paragraph  are  cumulative of all other rights which it
may have by law or otherwise.

     8. Notice to the Parties shall be given as provided  below.  Whenever under
the terms hereof the time for giving a notice or  performing an act falls upon a
Saturday, a Sunday or a banking holiday in New York, such time shall be extended
to the next day on which the Escrow Agent is open for business.

     9. The Escrow Agent may, in its sole  discretion,  resign and terminate its
position  hereunder  at any time  following  thirty (30)  calendar  days written

of  resignation  specified  in such notice,  the Parties will jointly  appoint a
successor  escrow agent. On the effective date of such  appointment,  the Escrow
Agent shall  deliver  this Escrow  Agreement  together  with any and all related
instruments or documents and all of the funds,  securities,  documents and other
assets  held in escrow  hereunder  to any  successor  escrow  agent  selected in
writing by Parties to this Agreement.  If a successor  escrow agent has not been
appointed  prior to the  expiration of thirty (30)  calendar days  following the
date  of  notice  of  such  resignation,   then  (i)  the  Escrow  Agent's  sole
responsibility  after that time shall be



to safekeep the property  held in escrow by it hereunder  until receipt by it of
designation  of a successor  escrow agent and (ii) the Escrow Agent may petition
any court of competent  jurisdiction  for the appointment of a successor  escrow
agent, or other  appropriate  relief.  Any such resulting  appointment  shall be
binding upon all the Parties to this Agreement.

     10. The Parties to this  Agreement may by mutual  written  agreement with a
copy of such  agreement  forwarded to the Escrow Agent at any time  substitute a
new escrow agent by giving ten (10) days notice  thereof to the Escrow Agent and
paying all fees and  expenses  due to the Escrow  Agent.  Any such  substitution
shall terminate all obligations and duties of the Escrow Agent hereunder. On the
effective  date of such  substitution,  the  Escrow  Agent  shall  deliver  this
Agreement together with any and all related  instruments or documents and all of
the funds, securities,  documents and other assets held in escrow hereunder to a
successor escrow agent that the Parties have selected in writing.

     11. The Escrow Agent shall  receive the fees provided in Appendix B hereto.
Except as set  forth in  Section  5(b)  above,  the  Escrow  Agent  shall not be
permitted  to utilize the Escrow Fund to cover any of its fees or  expenses.  As
between  themselves,  KCS and TMM agree that all fees and expenses of the Escrow
Agent shall be paid equally (50% by KCS and 50% by TMM).

     12.  Any  modification  of this  Agreement  or any  additional  obligations
assumed by any party  hereto  shall be binding  only if  evidenced  by a writing
signed by each of the parties  hereto.  Upon  distribution in full of the Escrow
Fund,  this Agreement  shall be thereupon  terminated and of no further force or
effect;  provided  that the  provisions  of Section  5(b) and 11 (for the period
prior to such  termination,  resignation  or  substitution)  shall  survive  the
termination of this Agreement and the  resignation or substitution of the Escrow
Agent.

     13. This  Agreement  shall be governed by the laws of the state of New York
