                            COMPX INTERNATIONAL INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 -  Basis of presentation:

     The consolidated balance sheet of CompX International Inc. and Subsidiaries
(collectively,  the  "Company") at December 31, 2003 has been condensed from the
Company's  audited   consolidated   financial   statements  at  that  date.  The
consolidated balance sheet at March 31, 2004 and the consolidated  statements of
income,  comprehensive  income,  stockholders'  equity  and cash  flows  for the
interim periods ended March 31, 2003 and 2004 have been prepared by the Company,
without audit. In the opinion of management, all adjustments, consisting only of
normal  recurring  adjustments,  necessary  to present  fairly the  consolidated
financial  position,  results of operations  and cash flows have been made.  The
results of operations for the interim periods are not necessarily  indicative of
the  operating  results  for a  full  year  or  of  future  operations.  Certain
information  normally  included in financial  statements  prepared in accordance
with accounting  principles  generally  accepted in the United States of America
("GAAP") has been condensed or omitted. The accompanying  consolidated financial
statements  should be read in  conjunction  with the Company's  Annual Report on
Form 10-K for the year ended December 31, 2003 (the "2003 Annual Report").

     Basic earnings per share of common stock is based upon the weighted average
number of common shares actually  outstanding  during each period. The impact of
all outstanding stock options on diluted earnings per share was antidilutive.

     Commitments and contingencies are discussed in "Management's Discussion and
Analysis of Financial  Condition and Results of Operations"  and the 2003 Annual
Report.

     At March  31,  2004,  Valhi,  Inc.  (NYSE:  VHI) and  Valhi's  wholly-owned
subsidiary Valcor,  Inc. owned an aggregate of 69% of the Company's  outstanding
common stock,  and a wholly owned subsidiary of Titanium Metals  Corporation,  a
less than majority  affiliate of Valhi,  owned an additional 8% of the Company's
outstanding common stock. At March 31, 2004, Contran Corporation holds, directly
or through subsidiaries,  approximately 90% of Valhi's outstanding common stock.
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,  or is held by Mr.  Simmons or
persons or other entities related to Mr. Simmons.  Mr. Simmons,  the Chairman of
the Board of each of Contran,  Valhi and Valcor,  may be deemed to control  such
companies and the Company.

     Stock options. As disclosed in the 2003 Annual Report, the Company accounts
for  stock-based  employee  compensation  related  to stock  options  using  the
intrinsic value method in accordance with  Accounting  Principles  Board Opinion
("APBO")  No. 25,  Accounting  for Stock  Issued to  Employees,  and its various
interpretations. Under APBO No. 25, no compensation cost is generally recognized
for fixed stock options in which the exercise  price is greater than or equal to
the market price on the grant date.  Compensation cost recognized by the Company
related to stock  options  in  accordance  with APBO No. 25 was not  significant
during the first three months of 2003 or 2004.

     The following  table  illustrates the effect on net income and earnings per
share if the Company had applied the fair value  recognition  provisions of SFAS
No.  123,  Accounting  for  Stock-Based  Compensation  to  stock-based  employee
compensation  related  to stock  options  for all  options  granted  on or after
January 1, 1995.

Note 8 -Currency forward exchange contracts:

     Certain of the Company's  sales  generated by its non-U.S.  operations  are
denominated in U.S.  dollars.  The Company  periodically  uses currency  forward
contracts to manage a portion of currency  exchange rate market risk  associated
with  receivables,  or similar  exchange rate risk associated with future sales,
denominated in a currency other than the holder's functional  currency.  At each
balance  sheet  date,  any  such   outstanding   currency  forward  contract  is
marked-to-market with any resulting gain or loss recognized in income currently.
These  contracts  are not accounted  for as hedging  instruments  under GAAP. At
December  31,  2003,  the  Company  held a series of  contracts  to manage  such
exchange  rate risk to exchange an aggregate  of U.S.  $4.2 million for Canadian
dollars at exchange  rates of Cdn.  $1.30 to Cdn.  $1.33 per U.S.  dollar.  Such
contracts  matured  through  February 2004. The exchange rate was Cdn. $1.31 per
U.S.  dollar at December 31, 2003. At March 31, 2004,  the Company held a series
of contracts to manage such  exchange rate risk to exchange an aggregate of U.S.
$3.0 million for Canadian  dollars at exchange rates of Cdn. $1.33 to Cdn. $1.34
per U.S. dollar.  Such contracts matured through May 2004. The exchange rate was
Cdn. $1.33 per U.S. dollar at March 31, 2004.

MANAGEMENT'S  DISCUSSION  AND  ANALYSIS OF  FINANCIAL  CONDITION  AND RESULTS OF
OPERATIONS
-------------------------------------------------------------------------------

Overview

     The Company  reported  net income of $1.6  million in the first  quarter of
2004  compared  to net  income of $.6  million  for the first  quarter  of 2003.
Fluctuations in currency exchange rates as compared to the prior year positively
impacted  net sales by $2.5  million;  however,  the  impact on net  income  was
insignificant.  The overall improvement in net income is primarily the result of
the favorable impact of cost reduction initiatives undertaken in 2002 and 2003.

     Currency.  CompX has substantial  operations and assets located outside the
United  States (in Canada,  the  Netherlands  and Taiwan).  A portion of CompX's
sales generated from its non-U.S. operations are denominated in currencies other
than the U.S.  dollar,  principally  the Canadian  dollar,  the euro and the New
Taiwan  dollar.  In  addition,  a portion of CompX's  sales  generated  from its
non-U.S.  operations (principally in Canada) are denominated in the U.S. dollar.
Most  raw  materials,  labor  and  other  production  costs  for  such  non-U.S.
operations are  denominated  primarily in local  currencies.  Consequently,  the
translated U.S. dollar values of CompX's foreign sales and operating results are
subject  to  currency  exchange  rate   fluctuations   which  may  favorably  or

                                     - 13 -

<PAGE>

unfavorably   impact  reported   earnings  and  may  affect   comparability   of
period-to-period  operating  results.  The effects of  fluctuations  in currency
exchange rates affect the CompX Waterloo and Thomas Regout segments,  and do not
materially affect the CompX Security Products segment.  During the first quarter
of 2004,  currency  exchange  rate  fluctuations  positively  impacted the sales
comparisons  with 2003;  however,  the  fluctuations  did not have a significant
impact  on  the  Company's  net  income  comparisons.   Currency  exchange  rate
fluctuations  of the Canadian dollar  positively  impacted sales of the Waterloo
segment by $1.1  million and currency  exchange  rate  fluctuations  of the euro
positively impacted sales of the Thomas Regout segment by $1.4 million.

     Net sales. Net sales increased $2.1 million, or 4%, to $53.1 million in the
first  quarter  of 2004 from  $51.0  million  in the first  quarter  of 2003 due
primarily  to the net effect of  fluctuations  in  currency  exchange  rates (as
discussed  above),  increased  sales volumes at CompX Security  Products,  price
increases on certain slide products and lower sales volumes of slide products at
Thomas Regout.

     Cost of goods sold.  The Company's  cost of goods sold  increased 2% in the
first quarter of 2004  compared to 2003 while net sales  increased 4% during the
same period.  The Company's  gross margin  percentage  increased from 17% in the
2003  period  to 19% in the 2004  period.  This  improvement  resulted  from the
favorable  impact of the cost  reduction  efforts  undertaken  in 2002 and 2003,
including   retooling  of  the  Company's  Byron  Center,   Michigan   facility,
consolidation of two Canadian  facilities into one facility and restructuring of
the Thomas  Regout  operations.  Gross margin  comparisons  were also  favorably
impacted by price  increases  on certain  products at CompX  Waterloo,  relative
changes in product mix at CompX  Security  Products in the first quarter of 2004
as compared to the first quarter of 2003, and expenses of approximately $400,000
during the first quarter of 2003  associated with the  consolidation  of the two
Canadian facilities.

     Selling, general, and administrative expense. As a percentage of net sales,
selling,  general,  and administrative  expense was 14% of net sales in 2003 and
2004.

     Operating  income.  Operating income in the first quarter of 2004 increased
to $2.7  million  compared to $1.8 million for the first  quarter of 2003.  As a
percentage of net sales,  operating income increased to 5% for the first quarter
of 2004 from 4% for the first  quarter of 2003 due to the  improvement  in gross
margins discussed above.

     Other general  corporate  income  (expense),  net. The  components of other
general  corporate  income  (expense),  net  are  summarized  in  Note  6 to the
Consolidated  Financial  Statements,  and  primarily  include  interest  income,
currency  exchange  transaction  gains  and  losses,  and  gains  and  losses on
disposals of other assets.  Net currency  exchange  transaction  gains  (losses)
improved  approximately  $738,000  from the first  quarter  of 2003 to the first
quarter of 2004 because the intra-quarter swings in currency exchange rates were
less volatile in 2004.

     Interest  expense.  Interest  expense declined in the first quarter of 2004
compared to the first quarter of 2003 due  primarily to lower average  levels of
outstanding debt.

     Provision  for income  taxes.  The  principal  reasons  for the  difference
between CompX's effective income tax rates and the U.S. federal statutory income
tax rates are  explained  in Note 7 to the  Consolidated  Financial  Statements.
Income  tax rates vary by  jurisdiction  (county  and/or  state),  and  relative
changes  in the  geographic  mix of  CompX's  pre-tax  earnings  can  result  in
fluctuations in the effective income tax rate.

     Outlook.  The Company expects that weak market  conditions will continue in
the office furniture market, the primary end-market for the Company's  products,
during  2004.  Competitive  pricing  pressures  are expected to continue to be a
challenge as foreign  manufacturing,  particularly in China, gains market share.
The  Company  has  responded  to the  competitive  pricing  pressure  in part by
reducing  production  cost  through  product  reengineering  or  improvement  in
manufacturing   processes,   moving  production  to  lower-cost  facilities  and
providing  value-added customer support services that foreign  manufacturers are
generally unable to provide.  However,  in some cases the Company has determined
to forgo  unprofitable  sales in response to the competitive  pricing pressures.
The Company will continue to focus on cost  improvement  initiatives,  utilizing
lean  manufacturing  techniques and prudent balance sheet management in order to
minimize  the impact of lower  sales to the  office  furniture  industry  and to
develop value-added customer relationships with additional focus on sales of the
Company's  higher-margin ergonomic computer support systems to improve operating
results.  The Company  currently  expects to realize annual cost savings of $3.5
million  to $4  million as the result of the  current  Thomas  Regout  headcount
reduction. However, the Company continues with its ongoing strategic analysis of
the Thomas  Regout  operations,  and  additional  actions  could be taken in the
future that could result in charges for asset  impairment,  including  goodwill,
and other costs in future periods. These actions, along with other activities to
eliminate  excess  capacity,  are  designed  to  position  the  Company  to more
effectively  concentrate  on both new  product and new market  opportunities  to
improve Company profitability.

Liquidity and Capital Resources

Summary.

     The Company's  primary  source of liquidity on an ongoing basis is its cash
flow from  operating  activities,  which is  generally  used to (i) fund capital
expenditures,  (ii) repay short-term indebtedness incurred primarily for working
capital  purposes and (iii) provide for the payment of dividends (if  declared).
From time-to-time, the Company will incur indebtedness, primarily for short-term
working capital needs or to fund capital  expenditures.  From time-to-time,  the
Company  may also sell assets  outside  the  ordinary  course of  business,  the
proceeds  of  which  are  generally  used  to  repay   indebtedness   (including
indebtedness  which may have been  collateralized by the assets sold) or to fund
capital expenditures.

     At  March  31,  2004,  substantially  all  of  the  Company's  indebtedness
consisted  of the $14  million  outstanding  under  its  revolving  bank  credit
facility  that  matures  in  January  2006.  Because  the  maturity  date of the
indebtedness  isn't until 2006,  the Company does not expect it will be required
to use any of its cash flow from operating  activities  generated during 2004 to
repay  indebtedness,  although  it  may  choose  to do so (as  evidenced  by the
Company's  repayment  of a net $12  million  under  the  revolving  bank  credit
facility during the first quarter of 2004).

  Consolidated cash flows.

     Operating  activities.  Trends in cash  flows  from  operating  activities,
excluding  changes in assets and liabilities  have generally been similar to the
trends in the  Company's  earnings.  Changes  in assets and  liabilities  result
primarily  from the timing of production,  sales and purchases.  Such changes in
assets and liabilities generally tend to even out over time and result in trends
in cash flows from operating  activities  generally  reflecting earnings trends.
However,  period-to-period  relative  changes  in  assets  and  liabilities  can
significantly affect the comparability of cash flows from operating  activities.
Such  changes  in  assets  and  liabilities  resulted  in a net  use of  cash of
approximately $2.2 million in the first quarter of 2003 compared to a net use of
cash of $1.5 million in the first quarter of 2004.

                                     - 15 -
<PAGE>

     Investing  activities.  Net cash used by investing  activities totaled $2.0
million and $.6 million in the first quarter of 2003 and 2004, respectively.

     The capital  expenditures for 2004 relate primarily to equipment  additions
designed to utilize new technologies thereby increasing automation and improving
manufacturing efficiencies at the Company's facilities. Capital expenditures for
2004 are estimated at approximately $10 million, the majority of which relate to
projects  that  emphasize  improved  production  efficiency  and the shifting of
production  capacity to lower cost  facilities.  Firm purchase  commitments  for
capital projects not commenced at March 31, 2004 approximated $1.0 million.

     Financing  activities.  Net cash used by financing  activities totaled $1.3
million and $11.8 million in the first  quarter of 2003 and 2004,  respectively.
The Company paid a quarterly  dividend of $1.9 million,  or $.125 per share,  in
the first  quarter of 2003,  but the Company  suspended  its  regular  quarterly
dividend in the second  quarter of 2003.  During the first quarter of 2004,  the
Company repaid a net $12 million under its revolving bank credit facility.

     Provisions  contained in the Company's revolving bank credit facility could
result in the acceleration of such indebtedness prior to its stated maturity for
reasons  other than  defaults  from  failing to comply  with  typical  financial
covenants. For example, the credit agreement allows the lender to accelerate the
maturity  of the  indebtedness  upon a change of  control  (as  defined)  of the
borrower.  The terms of the credit agreement could result in the acceleration of
all or a portion of the  indebtedness  following a sale of assets outside of the
ordinary course of business.  Other than certain  operating  leases discussed in
the 2003 Annual Report,  neither CompX nor any of its subsidiaries or affiliates
are parties to any off-balance sheet financing arrangements.

     Management  believes  that cash  generated  from  operations  and borrowing
availability  under the Company's credit  facility,  together with cash on hand,
will be sufficient to meet the Company's  liquidity  needs for working  capital,
capital  expenditures,  debt  service  and  dividends.  To the  extent  that the
Company's  actual  operating  results  or  other  developments  differ  from the
Company's expectations, CompX's liquidity could be adversely affected.

     The Company periodically evaluates its liquidity requirements,  alternative
uses of capital,  capital needs and available  resources in view of, among other
things,  its capital  expenditure  requirements,  dividend  policy and estimated
future operating cash flows. As a result of this process, the Company has in the
past  and may in the  future  seek to raise  additional  capital,  refinance  or
restructure  indebtedness,  issue  additional  securities,  modify its  dividend
policy,  repurchase  shares of its common  stock or take a  combination  of such
steps to manage its  liquidity  and capital  resources.  In the normal course of
business,  the Company may review opportunities for acquisitions,  divestitures,
joint  ventures  or  other  business  combinations  in  the  component  products
industry.  In the event of any such transaction,  the Company may consider using
available  cash,   issuing   additional  equity  securities  or  increasing  the
indebtedness of the Company or its subsidiaries.

Forward Looking Information

     As  provided  by the  safe  harbor  provisions  of the  Private  Securities
Litigation  Reform Act of 1995, the Company cautions that the statements in this
Quarterly  Report on Form 10-Q relating to matters that are not historical facts
are  forward-looking   statements  that  represent   management's   beliefs  and

                                     - 16 -


<PAGE>

assumptions based on currently available information. Forward-looking statements
can be  identified  by the use of words such as  "believes,"  "intends,"  "may,"
"should," "anticipates," "expects" or comparable terminology,  or by discussions
of strategies  or trends.  Although the Company  believes that the  expectations
reflected in such forward-looking  statements are reasonable, it cannot give any
assurances that these expectations will prove to be correct.  Such statements by
their  nature   involve   substantial   risks  and   uncertainties   that  could
significantly  impact expected  results,  and actual future results could differ
materially from those described in such  forward-looking  statements.  Among the
factors  that could cause actual  future  results to differ  materially  are the
risks and  uncertainties  discussed in this Quarterly Report and those described
from  time to time in the  Company's  other  filings  with  the  Securities  and
Exchange  Commission.  While it is not  possible to identify  all  factors,  the
Company  continues  to face many  risks  and  uncertainties  including,  but not
limited to the following:

     o    Future supply and demand for the Company's products,
     o    Changes in costs of raw materials and other  operating  costs (such as
          energy costs),
     o    General global economic and political conditions,
     o    Demand for office furniture,
     o    Service industry employment levels,
     o    The possibility of labor disruptions,
     o    The ability to  implement  headcount  reductions  in a cost  effective
          manner within the  constraints of non-U.S.  governmental  regulations,
          and the timing and amount of any cost savings,
     o    Competitive products and prices,  including increased competition from
          low-cost manufacturing sources (such as China),
     o    Substitute products,
     o    Customer and competitor strategies,
     o    The introduction of trade barriers,
     o    The impact of pricing and production decisions,
     o    Fluctuations  in the  value  of the  U.S.  dollar  relative  to  other
          currencies (such as the euro, Canadian dollar and New Taiwan dollar),
     o    Potential    difficulties   in   integrating   completed   or   future
          acquisitions,
     o    Uncertainties associated with new product development,
     o    Environmental  matters (such as those requiring emission and discharge
          standards for existing and new facilities),
     o    The ability of the Company to renew or refinance  its  revolving  bank
          credit facility,
     o    The ultimate outcome of income tax audits,
     o    The impact of current or future government regulations,
     o    Possible future litigation and
     o    Other risks and uncertainties.

Should one or more of these risks  materialize  (or the  consequences  of such a
development worsen) or should the underlying assumptions prove incorrect, actual
results could differ  materially from those forecasted or expected.  The Company
disclaims  any  intention  or  obligation  to update  publicly  or  revise  such
statements whether as a result of new information, future events or otherwise.

ITEM 4. Controls and Procedures.

     The Company maintains a system of disclosure  controls and procedures.  The
term  "disclosure  controls and  procedures,"  as defined by  regulations of the
Securities  and  Exchange  Commission  (the  "SEC"),  means  controls  and other
procedures that are designed to ensure that information required to be disclosed
in the reports that the Company files or submits to the SEC under the Securities
Exchange Act of 1934, as amended (the "Act"), is recorded, processed, summarized
and  reported,  within the time periods  specified in the SEC's rules and forms.

                                     - 17 -

<PAGE>

Disclosure  controls and procedures include,  without  limitation,  controls and
procedures  designed to ensure that information  required to be disclosed by the
Company  in the  reports  that it files or  submits  to the SEC under the Act is
accumulated  and  communicated  to  the  Company's  management,   including  its
principal  executive  officer and its principal  financial  officer,  or persons
performing  similar  functions,  as appropriate to allow timely  decisions to be
made regarding required disclosure.  Each of David A. Bowers, the Company's Vice
Chairman of the Board,  President  and Chief  Executive  Officer,  and Darryl R.
Halbert,  the Company's Vice President,  Chief Financial Officer and Controller,
have evaluated the Company's  disclosure controls and procedures as of March 31,
2004. Based upon their evaluation,  these executive officers have concluded that
the Company's disclosure controls and procedures are effective as of the date of
such evaluation.

     The Company also  maintains a system of internal  controls  over  financial
reporting.  The term "internal control over financial  reporting," as defined by
regulations  of the SEC, means a process  designed by, or under the  supervision
of, the  Company's  principal  executive and principal  financial  officers,  or
persons  performing  similar  functions,  and effected by the Company's board of
directors,  management  and other  personnel,  to provide  reasonable  assurance
regarding  the  reliability  of  financial  reporting  and  the  preparation  of
financial  statements  for  external  purposes  in  accordance  with  accounting
principles  generally  accepted in the United  States of America  ("GAAP"),  and
includes those policies and procedures that:

     o    Pertain  to the  maintenance  of  records  that in  reasonable  detail
          accurately and fairly reflect the transactions and dispositions of the
          assets of the Company.
     o    Provide  reasonable   assurance  that  transactions  are  recorded  as
          necessary to permit preparation of financial  statements in accordance
          with GAAP, and that receipts and expenditures of the Company are being
          made  only  in  accordance  with   authorizations  of  management  and
          directors of the Company, and
     o    Provide reasonable  assurance regarding prevention or timely detection
          of  unauthorized  acquisition,  use or  disposition  of the  Company's
          assets that could have a material effect on the Company's consolidated
          financial statements.

There has been no change to the  Company's  system  of  internal  controls  over
financial  reporting during the quarter ended March 31, 2004 that has materially
affected,  or is reasonably likely to materially affect, the Company's system of
internal controls over financial reporting.
