                        Report of Independent Accountants



To the Administrative Committee of
 CompX Contributory Retirement Plan

In our opinion, the accompanying statements of net assets available for benefits
and the  related  statement  of  changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of CompX Contributory Retirement Plan (the "Plan") at December 31, 2000 and 2001
and the changes in net assets available for benefits for the year ended December
31, 2001 in conformity  with  accounting  principles  generally  accepted in the
United States of America.  These financial  statements are the responsibility of
the  Plan's  management;  our  responsibility  is to express an opinion on these
financial  statements  based on our  audits.  We  conducted  our audits of these
statements  in  accordance  with auditing  standards  generally  accepted in the
United  States of America  which  require  that we plan and perform the audit to
obtain reasonable  assurance about whether the financial  statements are free of
material  misstatement.  An audit includes examining,  on a test basis, evidence
supporting the amounts and  disclosures in the financial  statements,  assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of Schedule of
Nonexempt  Transactions and Schedule of Assets Held for Investment  Purposes are
presented for the purpose of additional  analysis and are not a required part of
the basic financial statements but are supplementary information required by the
Department of Labor's Rules and Regulations  for Reporting and Disclosure  under
the  Employee  Retirement  Income  Security  Act  of  1974.  These  supplemental
schedules are the  responsibility  of the Plan's  management.  The  supplemental
schedules have been subjected to the auditing  procedures  applied in the audits
of the basic financial  statements and, in our opinion, are fairly stated in all
material  respects  in  relation to the basic  financial  statements  taken as a
whole.

                       COMPX CONTRIBUTORY RETIREMENT PLAN

                          NOTES TO FINANCIAL STATEMENTS

Note 1 - Description of Plan and significant accounting policies:


     General.  The following  description of the Compx  Contributory  Retirement
Plan (the "Plan") provides only general  information.  Participants should refer
to the Plan agreement for a more complete description of the Plan's provisions.

     The Plan is a defined  contribution plan which covers eligible salaried and
hourly  U.S.  employees  of  CompX   International  Inc.  and  its  subsidiaries
(collectively,  the  "Employer").  Employees are eligible to  participate in the
Plan as of the first entry date, as defined,  concurrent  with or next following
the completion of one year of employment and attaining 20 years of age. The Plan
is subject to the provisions of the Employee  Retirement  Income Security Act of
1974, as amended ("ERISA").

     The Employer is a 69%-owned  subsidiary of Valhi, Inc. Valhi is a 94%-owned
subsidiary of Contran  Corporation.  Substantially all of Contran's  outstanding
voting stock is held by trusts  established for the benefit of certain  children
and  grandchildren  of Harold C. Simmons,  of which Mr. Simmons is sole trustee.
Mr. Simmons,  the Chairman of the Board and Chief  Executive  Officer of each of
Contran  and Valhi,  may be deemed to  control  each of such  companies  and the
Employer.

     Effective  October 1, 2001, the Thomas Regout USA Inc. Salary Deferral Plan
was merged into the Plan and all of the assets of such plan were  transferred to
the Plan.

     In September 2001, the undistributed  assets from Chicago Lock Company SEIU
Local 1  401(K)  Retirement  Plan  and  Chicago  Lock  Company  Employee  401(K)
Retirement Plan  (collectively,  the "Chicago  Plans") were transferred into the
Plan.  The Chicago Plans were  terminated  effective  December 31, 2000, and any
assets that could not be distributed to individual participants were transferred
to the Plan.

     Contributions.  The Plan permits  participants  to defer 1% to 15% of their
pre-tax  annual  compensation  as  contributions,  not to exceed a  deferral  of
$10,500  in 2001  (subject  to  adjustment  in future  years),  through  payroll
deductions.  The Employer's  contribution is based upon a profit-sharing formula
and the  Employer's  profit,  as defined,  during the Plan year.  The Employer's
contribution is allocated to participants'  accounts on a percentage or matching
basis relative to the  participants'  contributions for the year. The Employer's
contribution is reduced, as provided by the Plan, by nonvested amounts forfeited
by  participants  who  withdraw  from the Plan.  At December  31, 2000 and 2001,
unallocated  forfeited nonvested accounts were $18,627 and $21,274 respectively.
For the years ended  December 31, 2000 and 2001,  $20,615 and nil of forfeitures
were used to reduce employer contributions, respectively.

     Vesting and benefits.  Salary deferrals  (including  earnings  thereon) are
immediately  vested while Employer  contributions  (including  earnings thereon)
vest at the rate of 20% per year of service, as defined.

     Upon  termination  of  employment,   retirement,  death  or  disability,  a
participant  (or  beneficiary,  if applicable) may elect to receive either (i) a
lump sum amount equal to the vested value of the participant's  accounts or (ii)
installments  over a period of not more than 30 years.  With the  consent of the
Plan  administrators,  participants can borrow amounts from their vested account
balances, subject to certain limitations under the Plan.

     Benefits are recorded when paid.

     Participants'  accounts.  Participants can direct the Plan administrator to
invest, in 1% increments,  their account balance in  publicly-traded  registered
investment  companies or pooled funds  administered by Putnam  Investments or in
CompX  International  Inc.  common stock.  Below are the investment fund options
available to participants at December 31, 2001:

     The above fund descriptions provide only general information.  Participants
should refer to the Prospectus of each fund for a more complete description.

     Each participant's account is credited with the participant's  contribution
and an allocation of the Employer's  contribution and Plan earnings, and charged
with  an  allocation  of  administrative  expenses.  Allocations  are  based  on
participant earnings, matching or account balances, as defined in the Plan.

     In addition to the Putnam Funds, a "Loan Fund" is maintained to account for
loans to participants,  as permitted by the Plan. These loans, which are secured
by the balance in the participant's account, bear interest at rates ranging from
5.75% to 10.5% and mature through 2016.

     Plan termination.  The Employer has the right under the Plan to discontinue
its  contributions at any time and to terminate the Plan, in compliance with the
provisions of ERISA.  In the event the Plan is  terminated,  the accounts of all
participants will become fully vested.

     Basis of accounting.  The financial  statements of the Plan are prepared in
accordance with accounting principles generally accepted in the United States of
America. Valuation of investments is more fully described in Note 2.

     Management estimates. The preparation of financial statements in conformity
with accounting  principles  generally  accepted in the United States of America
requires  management to make estimates and assumptions  that affect the reported
amounts  of  assets,  liabilities,   and  changes  therein,  and  disclosure  of
contingent assets and liabilities. Actual results may, in some instances, differ
from previously estimated amounts.

     Risks and  uncertainties.  The Plan provides for various investment options
in a variety of stocks, bonds, fixed income securities,  mutual funds, and other
investment securities.  Investment securities are exposed to various risks, such
as interest rate,  market, and credit risks. Due to the level of risk associated
with certain  investment  securities,  it is at least  reasonably  possible that
changes in the values of investment  securities  will occur in the near term and
that such changes could materially affect participants' account balances and the
amounts reported in the Plan's statement of net assets available for benefits.

     Expenses of  administering  the Plan.  The Plan  provides that the Employer
will generally reimburse the Plan for administrative  expenses paid by the Plan.
The Employer paid a significant portion of the 2001 administrative expenses.

     Tax status. The Plan has been notified by the Internal Revenue Service that
it is a qualified  plan under Section  401(a) and Section 401(k) of the Internal
Revenue Code (the  "Code"),  and is therefore  exempt from federal  income taxes
under provisions of Section 501(a) of the Code.

     The Plan has been amended since it was notified of its exempt status by the
Internal Revenue Service. Management believes the Plan currently is designed and
operates  in  accordance  with  the  applicable  requirements  of the  Code  and
therefore  remains exempt from federal income taxes under  provisions of Section
501(a) of the Code. In February 2002, the Plan submitted the Plan's  document to
the Internal Revenue Service for approval.

Note 2 - Investments:

     General.  The  assets  of the  Plan are  held  and the  related  investment
transactions  are  executed by Putnam  Fiduciary  Trust  Company as trustee (the
"Trustee")  of the CompX  Master  401(k)  Plan  Trust (the  "Trust").  The Trust
invests  in  publicly-traded  registered  investment  companies,   pooled  funds
administered by Putnam  Investments and CompX  International Inc. class A common
stock  (see Note 1). The Plan's  investments  are stated at fair value  based on
quoted  market  prices  and net  appreciation  (depreciation)  for  the  year is
reflected in the Plan's  statement of changes in net assets  available  for plan
benefits.  The net  appreciation  (depreciation)  consists of realized  gains or
losses and unrealized appreciation or depreciation on investments.

     The following presents  investments that represent 5 percent or more of the
Plan's net assets at year end:

Note 3 - Deposit of participant contributions:

     ERISA requires employees to transfer  participant elective deferrals to the
Plan's trust account  within a specified  period of time. In 2001,  the Employer
did not  transfer  certain  contributions  within  the time  required  by ERISA.
However,  all  contributions  have been transferred to the Plan's trust account,
and as prescribed by the regulations, additional amounts have been contributed.
