      NOW,  THEREFORE,  in  consideration of the premises and promises set forth

      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
for the  Services  described  in  paragraphs  1(a) and  1(b)  above  payable  in
quarterly  installments of $79,500 plus all  out-of-pocket  expenses incurred in

amount equal to the product of $500  multiplied by the number of days devoted by
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
shall  agree  to a  pro-rata  reduction  of the  fees  due  hereunder  for  such
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
actions,  as the other party may  reasonably  request and as may  reasonably  by
required in order to effectuate  the purposes of this Agreement and to carry out
