INTERCORPORATE SERVICES AGREEMENT


         This INTERCORPORATE SERVICES AGREEMENT (the "Agreement"),  effective as
of January 1, 2000, amends and supersedes that certain  Intercorporate  Services
Agreement effective as of January 1, 1999 by and between CONTRAN CORPORATION,  a
Delaware  corporation  ("Contran"),  and VALHI,  INC.,  a  Delaware  corporation
("Valhi").

                                    Recitals

         A. Without  direct  compensation  from Valhi,  employees  and agents of
Contran  and  affiliates  of  Contran  perform  (i)  management,  financial  and
administrative  functions  for  Valhi  and  (ii)  pilot  services  and  aircraft
management functions with respect to certain aircraft owned or leased by Valhi.

         B. Without direct  compensation  from Contran,  employees and agents of
Valhi perform certain  management,  financial and  administrative  functions for
Contran.

         C. Neither  Contran nor Valhi  separately  maintain  the full  internal
capability to perform all  necessary  management,  financial and  administrative
functions that such corporation requires.

         D. The cost of  maintaining  the  additional  personnel  by each  party
necessary to perform the functions  provided by the other party pursuant to this
Agreement would exceed the amount charged to such party that is contained in the
net fee set forth in Section 4 of this Agreement and the terms of this Agreement
are no less  favorable  to each party than could  otherwise  be obtained  from a
third party for comparable services.

         E. Each party  desires to continue  receiving  the  services  presently
provided  by the other  party and the other  party is  willing  to  continue  to
provide such services under the terms of this Agreement.

                  (d) Consultation  and assistance in performing  internal audit

         Section 3.  Miscellaneous  Services.  It is the  intent of the  parties
hereto that each party to this Agreement provide (a "Providing Party") only such
Services as are requested by the other party (a "Receiving Party") in connection
with (i) routine management,  financial and administrative  functions related to
the ongoing  operations of the  Receiving  Party and not with respect to special
projects,  including  corporate  investments,  acquisitions and divestitures and
(ii) with  respect to Contran  Services,  pilot  services  and routine  aircraft
management  functions for aircraft owned or leased by Valhi.  The parties hereto
contemplate  that the Services  rendered by a Providing Party in connection with
the conduct of each  Receiving  Party's  business will be on a scale compared to
that existing on the  effective  date of this  Agreement,  adjusted for internal
corporate  growth or contraction,  but not for major  corporate  acquisitions or
divestitures,  and  that  adjustments  may be  required  to the  terms  of  this
Agreement in the event of such major  corporate  acquisitions,  divestitures  or
special  projects.  Each  Receiving  Party will continue to bear all other costs
required  for  outside  services  including,  but not  limited  to, the  outside
services of attorneys,  auditors,  trustees,  consultants,  transfer  agents and
registrars,  and it is expressly understood that each Providing Party assumes no
liability for any expenses or services other than those stated in this Agreement
to be  provided  by  such  party.  With  respect  to  aircraft  covered  by this
Agreement,  Valhi  shall  continue  to  bear  all  costs  associated  with  such
aircraft's ownership,  storage, operation,  maintenance,  insurance, taxes, fees
and pilot expenses, other than such pilot's employment and benefits. In addition
to the amounts  charged to a Receiving Party for Services  provided  pursuant to
this Agreement,  such Receiving Party will pay the Providing Party the amount of
out-of-pocket costs incurred by the Providing Party in rendering such Services.

         Section 4. Net Fee for  Services.  Valhi agrees to pay to Contran a net
fee of $169,250  quarterly,  commencing as of January 1, 2000,  pursuant to this
Agreement.

         Section  5.  Original  Term.  Subject  to the  provisions  of Section 6
hereof,  the original  term of this  Agreement  shall be from January 1, 2000 to
December 31, 2000.

         Section  6.   Extensions.   This  Agreement  shall  be  extended  on  a
quarter-to-quarter  basis  after the  expiration  of its  original  term  unless
written notification is given by Contran or Valhi thirty (30) days in advance of
the first  day of each  successive  quarter  or  unless  it is  superseded  by a
subsequent written agreement of the parties hereto.

         Section 7. Limitation of Liability.  In providing  Services  hereunder,
each  Providing  Party shall have a duty to act, and to cause its agents to act,
in a  reasonably  prudent  manner,  but no  Providing  Party  nor  any  officer,
director,  employee or agent of such party nor or its affiliates shall be liable
to a Receiving Party for any error of judgment or mistake of law or for any loss
incurred  by the  Receiving  Party in  connection  with the matter to which this
Agreement relates,  except a loss resulting from willful misfeasance,  bad faith
or gross negligence on the part of the Providing Party.

         Section 8.  Indemnification.  Each Receiving  Party shall indemnify and
hold harmless the Providing Party, its affiliates and their respective officers,
directors  and  employees  from and  against  any and all  losses,  liabilities,
claims,  damages,  costs  and  expenses  (including  attorneys'  fees and  other
expenses  of  litigation)  to which  such  Providing  Party or person may become
subject  arising out of the  Services  provided by such  Providing  Party to the
Receiving  Party  hereunder,  provided that such indemnity shall not protect any
person against any liability to which such person would  otherwise be subject by
reason of willful misfeasance, bad faith or gross negligence on the part of such
person.

         Section 9. Further Assurances.  Each of the parties will make, execute,
acknowledge and deliver such other instruments and documents,  and take all such
other actions,  as the other party may reasonably  request and as may reasonably
be required in order to effectuate  the purposes of this  Agreement and to carry
out the terms hereof.

         Section 10. Notices.  All communications  hereunder shall be in writing
and shall be addressed,  if intended for Contran,  to Three Lincoln Centre, 5430
LBJ Freeway, Suite 1700, Dallas, Texas 75240, Attention:  Chairman of the Board,

Dallas, Texas 75240, Attention: President or such other address as it shall have

         Section 11. Amendment and Modification.  Neither this Agreement nor any
term hereof may be  changed,  waived,  discharged  or  terminated  other than by
agreement in writing signed by the parties hereto.

         Section 12. Successor and Assigns. This Agreement shall be binding upon
and inure to the  benefit of Contran and Valhi and their  respective  successors
and  assigns,  except  that  neither  party may  assign  its  rights  under this
Agreement without the prior written consent of the other party.

         Section 13.  Governing  Law. This  Agreement  shall be governed by, and
construed and interpreted in accordance with, the laws of the state of Texas.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed and delivered as of the date first above written.
