                      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  NL  INDUSTRIES,  INC.,  a  New  Jersey
corporation. ("Recipient").

                                   Recitals

      A.  Harold C.  Simmons,  an  employee  of Contran  and a director  and the
chairman of the board of  Recipient,  performs  certain  advisory  functions for
Recipient,  which  functions are unrelated to his function as a director and the
chairman of the board of Recipient, without direct compensation from Recipient.

      B. Recipient does not separately  maintain the full internal capability to
perform all necessary advisory functions that Recipient requires.

      C. The cost of engaging the advisory  services of someone  possessing  Mr.
Simmons'  expertise  and the cost of  maintaining  the  personnel  necessary  to
perform the functions  provided for by this  Agreement  would exceed the fee set
forth in Section 3 of this  Agreement,  and the terms of this  Agreement  are no
less favorable to Recipient than could  otherwise be obtained from a third party
for comparable services.

      D. Recipient desires to continue receiving the advisory services of Harold
C. Simmons and Contran is willing to continue to provide such services under the
terms of this Agreement.

                                  Agreement

      For and in  consideration  of the  mutual  premises,  representations  and
covenants herein contained, the parties hereto mutually agree as follows:

      Section 1. Services to be Provided.  Contran  agrees to make  available to
Recipient,  upon request, the following services (the "Services") to be rendered
by Harold C. Simmons:

            (a)   Consultation   and   assistance   in   the   development   and
      implementation of Recipient's  corporate  business  strategies,  plans and
      objectives; and

            (b) Such other  services as may be requested by Recipient  from time
      to time.

This  Agreement  does not apply to and the  Services  provided for herein do not
include any services that Harold C. Simmons may provide to Recipient in his role
as a director on  Recipient's  board of directors,  as chairman of such board of
directors or any other activity related to such board of directors.

      Section 2. Miscellaneous  Services. It is the intent of the parties hereto
that Contran provide only the Services requested by Recipient in connection with
routine  functions  related to the ongoing  operations of Recipient and not with
respect to special projects, including corporate investments,

rendered in  connection  with the conduct of  Recipient'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.  Recipient  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 Contran assumes no liability for
any  expenses or services  other than those  stated in Section 1. In addition to

Agreement,  Recipient  will pay to  Contran  the amount of  out-of-pocket  costs
incurred by Contran in rendering such Services.

advance of the first day of each  successive  quarter or unless it is superseded
by a subsequent written agreement of the parties hereto.

Contran  shall  have a duty  to act,  and to  cause  its  agents  to  act,  in a
reasonably  prudent  manner,  but  neither  Contran nor any  officer,  director,

any error of judgment or mistake of law or for any loss incurred by Recipient 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
Contran.

      Section  7.  Indemnification  of  Contran by  Recipient.  Recipient  shall
indemnify  and hold  harmless  Contran,  its  affiliates  and  their  respective
officers,  directors  and  employees  from  and  against  any  and  all  losses,

other  expenses of  litigation)  to which  Contran or any such person may become
subject  arising  out of the  Services  provided  by  Contran  to the  Recipient
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 8. 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.

                       INTERCORPORATE SERVICES AGREEMENT

      This INTERCORPORATE SERVICES AGREEMENT (the "Agreement") is made effective
as of January 1, 2000, by and between Titanium Metals Corporation  ("TIMET"),  a

      WHEREAS, TIMET desires that NL provide certain insurance, risk management,
loss control,  internal  audit,  and tax services to TIMET, as set forth in this
Agreement.

      NOW,  THEREFORE,  in  consideration of the premises and promises set forth
herein and for other good and valuable consideration the receipt and sufficiency
of which is hereby acknowledged, the parties to this Agreement agree as follows:

      1. Services Provided. NL will make available to TIMET and its subsidiaries
the following services (the "Services"):

            (a)   certain administration and management services with respect to
                  TIMET's insurance and risk management needs, including:

                  (i)   management  of  claims  (including   insured  and  self-
                        insured workers compensation and liability claims);

                  (ii)  budgeting and related activities;

                  (iii) coordination of property loss control program; and

                  (iv)  administration of TIMET's insurance  program,  excluding
                        all employee benefit and welfare related programs.

            (b)   consultation    and   assistance   in   tax   management   and
                  administration, including, without limitation, preparation and
                  filing  of  tax  returns,   tax  reporting,   examinations  by
                  government authorities and tax planning;

            (c)   consultation  and  assistance  in  performing  internal  audit
                  projects, as requested; and

            (d)   use of corporate aircraft.

      2. Fees for Services and  Reimbursement  of Expenses.  During the Term (as
defined below) of the Agreement, TIMET shall pay to NL an annual fee of $318,000

NL's internal auditors to providing  Services  described in paragraph 1(c) above
times  the  number  of  internal  auditors  providing  such  Services  plus  all
out-of-pocket   expenses   incurred  in  the   performance   of  such  Services.
Notwithstanding the foregoing,  in the event that TIMET determines,  in its sole
discretion,  that it no longer desires certain of the Services or NL determines,
in its sole  discretion,  that it no longer  desires to  provide  certain of the
Services, then TIMET or NL, as appropriate, shall provide the other party with a
thirty (30) day prior written notice of cancellation  describing the Services to
be terminated or  discontinued  and TIMET and NL during such  ninety-day  period

terminated or discontinued Services.

      3. Limitation of Liability. In providing Services hereunder, NL shall have
a duty to act, and to cause its agents to act, in a reasonably  prudent  manner,
but  neither  NL nor any  officer,  director,  employee  or agent of NL shall be
liable to TIMET or its  subsidiaries for any error of judgment or mistake of law
or for any loss incurred by TIMET or its  subsidiaries  in  connection  with the
matters to which this  Agreement  relates,  except a loss resulting from willful
misfeasance,  bad  faith or  gross  negligence  on the  part of NL or from  NL's
reckless disregard of obligations and duties under this Agreement.

      4. Indemnification of NL by TIMET. TIMET shall indemnify and hold harmless
NL, its subsidiaries and their respective officers, directors and employees from
and against any and all losses, liabilities, claims, damages, costs and expenses
(including reasonable attorneys' fees and other expenses of litigation) to which
such party may become  subject  arising out of the  provision by NL to TIMET and
its subsidiaries of any of the Services,  provided that such indemnity shall not
protect  any such  party  against  any  liability  to which  such  person  would
otherwise  be  subject  by reason  of  willful  misfeasance,  bad  faith,  gross
negligence or reckless disregard of obligations and duties hereunder.

      5. Further Assurance. Each of the parties will make, execute,  acknowledge
and  deliver  such  other  instruments  and  documents,  and take all such other
