     This proxy statement and the accompanying  proxy card or voting instruction
form are being furnished in connection  with the  solicitation of proxies by and

International Inc., a Delaware corporation ("CompX"), for use at the 2000 Annual
Meeting of Stockholders of CompX to be held on Thursday, May 11, 2000 and at any

Annual Meeting of  Stockholders  (the  "Notice") sets forth the time,  place and

                  QUORUM, VOTING RIGHTS AND PROXY SOLICITATION

     The record  date set by the Board of  Directors  for the  determination  of
stockholders  entitled  to notice of and to vote at the Meeting was the close of
business on March 22, 2000 (the "Record  Date").  As of the Record  Date,  there
were  6,149,380  shares of CompX Class A Common Stock and  10,000,000  shares of
CompX Class B Common Stock issued and  outstanding.  Each share of CompX Class A
Common  Stock  entitles  its holder to one vote on all matters to be acted on at
the Meeting. Each share of CompX Class B Common Stock entitles its holder to ten
votes  with  respect  to the  election  of  directors  and one vote on all other
matters to be acted on at the Meeting.  The presence,  in person or by proxy, of
the holders of a majority of the votes of CompX Common Stock entitled to vote at
the Meeting,  counted as a single class, is necessary to constitute a quorum for
the conduct of business at the  Meeting.  Shares of CompX  Common Stock that are
voted to abstain from any business coming before the Meeting and  broker/nominee
non-votes  will be counted as being in attendance at the Meeting for purposes of
determining whether a quorum is present.

     A  plurality  of the  affirmative  votes of the  CompX  Class A and Class B
Common Stock, voting together as a single class,  represented and entitled to be
voted  at  the  Meeting,  is  necessary  to  elect  a  director  of  CompX.  The
accompanying  proxy  card  or  voting  instruction  form  provides  space  for a
stockholder to withhold  authority to vote for any or all of the nominees of the
Board of  Directors.  Neither  shares as to which the  authority  to vote on the
election of directors has been  withheld nor  broker/nominee  non-votes  will be
counted  as  affirmative  votes  to  elect  director  nominees  to the  Board of
Directors.

     Except as applicable laws may otherwise provide,  any other matter that may
properly come before the Meeting will require the affirmative vote of a majority
of the votes cast at the Meeting for approval.

     Unless  otherwise  specified,  the agents  designated  in the proxy card or
voting  instruction  form will  vote the  shares  represented  by a proxy at the
Meeting  "FOR"  the  election  of the  nominees  for  director  of the  Board of
Directors  and, to the extent  allowed by the federal  securities  laws,  in the
discretion  of the agents on any other matter that may properly  come before the
Meeting.

     Valcor,  Inc.  ("Valcor")  directly holds 100% of the outstanding shares of
CompX Class B Common Stock as of the Record Date, which represents approximately
61.9% of the  outstanding  shares of CompX Class A and B Common Stock  combined.
Valcor is a wholly  owned  subsidiary  of  Valhi,  Inc.  ("Valhi")  and both are
affiliates   of  Contran   Corporation   ("Contran").   Valhi   directly   holds
approximately 6.1% of the outstanding shares of CompX Class A Common Stock as of
the Record Date  (approximately  2.3% of the combined  voting power of the CompX
Common  Stock).  Together  Valcor  and  Valhi  hold  approximately  64.2% of the
combined  voting power of the CompX Common  Stock  (approximately  94.6% for the
election  of  directors)  as of the  Record  Date.  Both Valhi and  Contran  are
diversified holding companies that Harold C. Simmons may be deemed to control.

     Valcor and Valhi have  indicated  their  intention  to have their shares of
CompX  Common Stock  represented  at the Meeting and voted "FOR" the election of
each of the  nominees for  director of the Board of  Directors.  If Valcor alone
attends  the Meeting in person or by proxy and votes as  indicated,  the Meeting
will have a quorum present and the stockholders  will elect all the nominees for
the Board of Directors.

     Harris Trust and Savings  Bank or its  successor  ("Harris"),  the transfer
agent and  registrar for CompX Class A and Class B Common Stock as of the Record
Date,  has been  appointed by the Board of Directors to ascertain  the number of
shares represented,  receive proxies and ballots, tabulate the vote and serve as
inspector of election at the Meeting.

     Each holder of record of CompX Common Stock giving the proxy  enclosed with
this proxy statement may revoke it at any time prior to the voting of such stock
at the  Meeting  by  delivering  to Harris a written  revocation  of the  proxy,
delivering to Harris a duly executed  proxy bearing a later date or by voting in
person at the Meeting.  Attendance by a  stockholder  at the Meeting will not in
itself constitute the revocation of such stockholder's proxy.

     Employees  participating  in the National  Cabinet Lock, Inc.  Contributory
Retirement Plan, as amended (the "NCL 401(k) Plan"),  and The 401(k) Plan of The
Fort Lock  Corporation  who are beneficial  owners of CompX Class A Common Stock
under such plans may use the enclosed  voting  instruction  form to instruct the
respective  plan  trustee how to vote the shares held for such  employees.  Each
trustee will,  subject to the terms of the respective  plan, vote such shares in
accordance with such instructions.

     The Board of  Directors is making this proxy  solicitation.  CompX will pay
all  expenses  related to the  solicitation,  including  charges for  preparing,
printing,  assembling and distributing all materials  delivered to stockholders.
In addition to solicitation by mail,  directors,  officers and regular employees
of CompX may solicit  proxies by  telephone  or in person for which such persons
will receive no  additional  compensation.  Upon request,  CompX will  reimburse
banking  institutions,  brokerage  firms,  custodians,  trustees,  nominees  and
fiduciaries for their reasonable out-of-pocket expenses incurred in distributing
proxy materials and voting  instructions to the beneficial owners of CompX Class
A Common Stock that such entities hold of record.

                              ELECTION OF DIRECTORS

     The bylaws of CompX  provide that the Board of Directors  shall  consist of
not less than one and not more than fifteen persons,  as determined from time to
time by the Board of Directors  in its  discretion.  The Board of Directors  has
currently  set the number of directors at seven.  The  directors  elected at the
Meeting will hold office until the 2001 Annual Meeting of Stockholders and until
their  successors  are duly  elected and  qualified  or their  earlier  removal,
resignation or death.

     All of the  nominees  are  currently  directors  of CompX  whose terms will
expire at the Meeting.  All of the nominees have agreed to serve if elected.  If
any nominee is not available for election at the Meeting,  a proxy will be voted
"FOR" an alternate nominee to be selected by the Board of Directors,  unless the
stockholder  executing such proxy withholds  authority to vote for such nominee.
The  Board of  Directors  believes  that  all of its  present  nominees  will be
available for election at the Meeting and will serve if elected.

internal auditing, the system of internal accounting controls and internal audit
results;  and to direct and  supervise  special  audit  inquiries.  The  current
members of the audit committee are Edward J. Hardin (chairman) and Paul M. Bass,

committee performing a similar function. All matters that would be considered by
such a  committee  are acted upon by the full Board of  Directors.  The Board of
Directors will consider recommendations by stockholders of CompX with respect to
the election of directors if such  recommendations  are  submitted in writing to
the secretary of CompX and received not later than December 31 of the year prior
to the next  annual  meeting of  stockholders.  Such  recommendations  should be
accompanied  by a full  statement  of  qualifications  and  confirmation  of the
nominee's willingness to serve.

has  previously  established,  and  from  time  to  time  may  establish,  other

     stock  options  that  such  person  or group  may  exercise  within 60 days

     Contran's outstanding voting stock is held either by trusts established for
     the benefit of certain children and grandchildren of Harold C. Simmons (the
     "Trusts"),  of which Mr.  Simmons is the sole  trustee,  or by Mr.  Simmons
     directly.  As sole trustee of the Trusts, Mr. Simmons has the power to vote
     and direct  the  disposition  of the  shares of  Contran  stock held by the
     Trusts. Mr. Simmons, however, disclaims beneficial ownership of any Contran
     shares that the Trusts hold.

     Harold C. Simmons is the chairman of the board and chief executive  officer
     of Valcor, Valhi, VGI, National,  NOA, Dixie Holding, Dixie Rice, Southwest
     and Contran.  By virtue of the holding of the offices,  the stock ownership
     and his service as trustee,  all as  described  above,  Mr.  Simmons may be
     deemed to control certain of such entities,  and Mr. Simmons and certain of
     such entities may be deemed to possess indirect beneficial ownership of the
     shares of CompX Common Stock directly held by Valcor or Valhi. Mr. Simmons,
     however, disclaims beneficial ownership of the shares of CompX Common Stock
     beneficially owned, directly or indirectly, by any of such entities.

     The Harold  Simmons  Foundation,  Inc. (the  "Foundation")  directly  holds
     approximately  0.5% of the  outstanding  shares of Valhi common stock.  The
     Foundation is a tax-exempt  foundation  organized for charitable  purposes.
     Harold C. Simmons is the chairman of the board and chief executive  officer
     of the Foundation and may be deemed to control the Foundation. Mr. Simmons,
     however, disclaims beneficial ownership of any shares of Valhi common stock
     held by the Foundation.

     The Contran Deferred  Compensation  Trust No. 2 (the "CDCT No. 2") directly
     holds approximately 0.4% of the outstanding Valhi common stock. Boston Safe
     Deposit  and Trust  Company  serves as trustee  of the CDCT No. 2.  Contran
     established  the CDCT No.  2 as an  irrevocable  "rabbi  trust"  to  assist
     Contran in meeting certain deferred  compensation  obligations that it owes
     to Harold C. Simmons.  If the CDCT No. 2 assets are insufficient to satisfy
     such  obligations,  Contran must  satisfy the balance of such  obligations.
     Pursuant to the terms of the CDCT No. 2, Contran  retains the power to vote
     the  shares  held by the CDCT No. 2,  retains  dispositive  power over such
     shares and may be deemed the indirect  beneficial owner of such shares. Mr.
     Simmons,  however,  disclaims  such  beneficial  ownership  of  the  shares
     beneficially  owned,  directly or indirectly,  by the CDCT No. 2, except to
     the extent of his interest as a beneficiary of the CDCT No. 2.

     The  Combined   Master   Retirement   Trust  (the  "Master   Trust")  holds
     approximately  0.1% of the outstanding  shares of Valhi common stock. Valhi
     established the Master Trust to permit the collective  investment by master
     trusts that maintain the assets of certain employee benefit plans Valhi and
     related  companies  adopt.  Harold C.  Simmons  is the sole  trustee of the
     Master Trust and a member of the trust investment  committee for the Master
     Trust. Paul M. Bass, Jr. is also a member of the trust investment committee
     for the Master  Trust.  Valhi's  board of directors  select the trustee and
     members of the trust investment  committee for the Master Trust.  Harold C.
     Simmons and Glenn R. Simmons are members of Valhi's  board of directors and
     along with David A. Bowers and Steven L. Watson are  participants in one or
     more of the employee  benefit  plans that invest  through the Master Trust.
     Each of such persons disclaims  beneficial  ownership of the shares held by
     the Master Trust,  except to the extent of his individual vested beneficial
     interest in the assets held by the Master Trust.

     For purposes of  calculating  the percentage  ownership of the  outstanding
     shares of Valhi  common stock as of the Record  Date,  1,186,200  shares of
     Valhi common stock that a subsidiary of NL, Valhi's majority-owned titanium
     dioxide pigments  subsidiary,  directly holds and 1,000,000 shares of Valhi
     common stock that Valmont  Insurance  Company  ("Valmont"),  a wholly owned
     subsidiary of Valhi,  directly  holds are excluded from the amount of Valhi

     these excluded shares as treasury stock for voting purposes.

     COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS AND OTHER INFORMATION

     Compensation  of  Directors.  During 1999,  directors of CompX who were not
also employees of CompX received an annual retainer of $15,000 paid in quarterly
installments,  plus a fee of $1,000 per day for  attendance at meetings and as a
daily rate ($125 per hour) for other services rendered on behalf of the Board of
Directors and/or committees thereof. In addition,  directors who were members of
the audit  committee or MD&C  Committee  received an annual  retainer of $1,000,
paid in quarterly  installments,  for each committee on which they served. CompX
also reimbursed its nonemployee  directors for reasonable  expenses  incurred in
attending  meetings and in the performance of other services  rendered on behalf
of the Board of Directors and/or its committees. CompX paid director fees during
1999 to Paul M. Bass, Jr., Edward J. Hardin,  Ann Manix,  Glenn R. Simmons and a
former director, Robert W. Singer.

     In February 1999, the MD&C Committee,  upon the recommendation of the Board
of Directors,  approved under the 1997 Plan annual grants to CompX's nonemployee
directors.  Each annual  grant  consists  of a grant at each  annual  meeting of
CompX's  stockholders  of 500  shares  of CompX  Class A Common  Stock and stock
options  exercisable  for 2,000  shares  of CompX  Class A Common  Stock,  which
options  will have an exercise  price equal to the closing  sales price of CompX
Class A Common Stock on the date of grant,  have a term of 10 years and vest 20%
over the first five anniversaries of the date of grant.

     CompX and Valhi are parties to an  intercorporate  services  agreement (the
"Valhi ISA") pursuant to which Valhi provided  certain  services to CompX during
1999,  including  services that Steven L. Watson rendered to CompX. See "Certain
Relationships and Transactions-Intercorporate Services Agreements."

(1)  No shares of restricted stock were granted to the named executive  officers
     nor payouts  made to the named  executive  officers  pursuant to  long-term
     incentive  plans  during the last three years.  Therefore,  the columns for
     such compensation have been omitted.

(2)  Other annual compensation for each of the named executive officers included
     perquisites,  which  perquisites  were  less than the  level  required  for
     reporting  pursuant to Commission  rules.  Therefore,  the column for other
     annual compensation has been omitted.

     subject to the  consummation  of CompX's  initial public  offering of CompX
     Class A Common  Stock (the "IPO Bonus Share  Awards").  Pursuant to Messrs.
     Compofelice's  and Bowers'  elections  under  section 83(b) of the Internal
     Revenue Code of 1986, as amended (the "Code"), CompX valued these IPO Bonus
     Share  Awards for  purposes  of the  compensation  table above based on the
     shares'  fair market  value at the time of the award  taking  into  account
     their illiquidity at the time of the award. In March 1998,  pursuant to the
     IPO Bonus Share  Awards,  CompX  issued to Messrs.  Compofelice  and Bowers
     100,000 and 16,220 shares of CompX Class A Common Stock, respectively.

     National  Cabinet Lock, Inc. Capital  Accumulation  Pension Plan, a defined

(7)  Waterloo   paid  Ronald  J.  Simmons  his  base  salary,   cash  bonus  and
     contributions  to his retirement  plan in Canadian  dollars.  CompX reports
     these  amounts  in the table  above in U.S.  dollars  based on the  average
     exchange  rates for 1999,  1998 and 1997 of CN$1.480 per US$1.00,  CN$1.478
     per US$1.00 and CN$1.382 per US$1.00, respectively.

(8)  Mr.  Simmons' 1998 bonus amount  includes a dollar amount for Mr.  Simmons'
     IPO Bonus Share Award.  CompX valued Mr. Simmons' IPO Bonus Share Award for
     purposes of the compensation  table above at the CompX Class A Common Stock
     initial public offering price of $20.00 per share. In March 1998,  pursuant
     to Mr.  Simmons' IPO Bonus Share Award,  CompX issued to Mr. Simmons 16,220
     shares of CompX Class A Common Stock.

(1)  Pursuant to the rules of the  Commission,  the amounts  under these columns
     reflect  calculations  at  assumed  5%  and  10%  appreciation  rates  and,
     therefore,  are not intended to forecast  future  appreciation,  if any, of
     CompX Class A Common Stock. The potential realizable value to the optionees
     was  computed as the  difference  between  the  appreciated  value,  at the
     expiration  dates of the stock  options,  of the CompX Class A Common Stock
     obtainable upon exercise of such stock options over the aggregate  exercise
     price of such stock options.

     The amount of gain to the  optionees is dependent on the amount of increase
     in the  price of CompX  Class A  Common  Stock,  which  would  benefit  all
     stockholders proportionately. These potentially realizable values are based
     solely on arbitrarily assumed rates of appreciation  required by applicable
     Commission regulations. Actual gains, if any, on stock option exercises are
     dependent on the future performance of CompX Class A Common Stock,  overall
     market conditions and the timing of the exercise thereof by each respective
     optionee. There can be no assurance that the amounts reflected in the table
     will be achieved.

(2)  This stock option is  exercisable  for shares of CompX Class A Common Stock
     and  becomes  exercisable  at a rate  of  20% on  each  of the  first  five
     anniversary  dates of the date of grant.  The exercise price for this stock
     option can be paid in already  owned shares of CompX Class A Common  Stock,
     provided  such  tendered  shares were held by the optionee for at least six
     months.

(3)  The  appreciated  value per share on January 25, 2009,  based on the $20.00
     per share  market value of a share of CompX Class A Common Stock on January
     25, 1999,  would be $32.58 and $51.87 at the hypothetical 5% and 10% rates,
     respectively.

(4)  The appreciated  value per share on February 17, 2009,  based on the $17.94
     per share market value of a share of CompX Class A Common Stock on February
     17, 1999,  would be $29.22 and $46.53 at the hypothetical 5% and 10% rates,
     respectively.

(5)  The $109,053,000  and  $225,194,000  amounts shown represent the cumulative
     increase in value  stockholders  would receive on all outstanding shares of
     CompX Class A Common Stock over a ten-year  period at the  hypothetical  5%
     and 10%  appreciation  rates,  respectively,  based on the $17.94 per share
     market  value  of the  6,148,580  shares  of  CompX  Class A  Common  Stock
     outstanding on the close of business February 17, 1999 and the reinvestment
     of cash  dividends  paid at a rate equal to CompX's cash dividend  payments
     initiated on December 31, 1999 of $0.125 per share per calendar quarter.

     Stock  Option   Exercises  and  Holdings.   The  following  table  provides
information, with respect to the named executive officers, concerning the amount
the named executive  officer realized in 1999 upon the exercise of stock options
for Valhi Common Stock and the value of  unexercised  stock options  exercisable
for CompX Class A Common  Stock or Valhi  Common  Stock held as of December  31,
1999. Neither CompX nor Valhi has granted any SARs.

(1)  The aggregate amount is based on the difference  between the exercise price
     of the individual  stock options and, as  applicable,  the $10.50 per share
     closing sales price of Valhi Common Stock and the $18.375 per share closing
     sales price of the CompX  Class A Common  Stock as reported on the New York
     Stock Exchange Composite Tape on December 31, 1999.

(2)  The amount  realized is based on the  difference  between the last reported
     sales  price per share of Valhi  Common  Stock as  reported on the New York
     Stock  Exchange  Composite  Tape on the date of exercise  and the  exercise
     price per share.

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section  16(a) of the  Exchange Act requires  CompX's  executive  officers,
directors  and  persons who own more than 10% of a  registered  class of CompX's
equity securities to file reports of ownership with the Commission, the New York
Stock Exchange, Inc. and CompX. Based solely on the review of the copies of such
forms and written  representations by certain reporting persons,  CompX believes
that for 1999 its executive  officers,  directors and 10% stockholders  complied
with all applicable filing requirements under Section 16(a).

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     During 1999, the MD&C  Committee  deliberated  on CompX  executive  officer
compensation.  The MD&C  Committee is currently  comprised of Paul M. Bass,  Jr.
(chairman) and Ann Manix, both nonemployee directors of CompX.

     In 1999 no CompX  executive  officer  deliberated  on the  compensation  of
executive  officers  of  another  entity  (as a  member  of the  other  entity's
compensation committee, board of directors or otherwise), one of whose executive
officers  deliberated on the  compensation of CompX's  executive  officers (as a
member of the MD&C Committee, the Board of Directors or otherwise).

     CompX and its  affiliates  engaged  and paid to Rogers & Hardin  LLP, a law
firm of which  CompX's  director  Edward J.  Hardin is a partner,  approximately
$75,000  in fees for  services  Rogers & Hardin  LLP  rendered  to CompX and its
affiliates in 1999. CompX expects that it and its affiliates will continue their
relationships with Rogers & Hardin LLP in 2000.

            COMPENSATION COMMITTEE'S REPORT ON EXECUTIVE COMPENSATION

     The MD&C  Committee  consists of individuals  who are neither  officers nor
employees  of  CompX  or  its  subsidiaries.  The  MD&C  Committee  reviews  and
recommends  compensation  policies and  practices  related to CompX's  executive
officers and other employees,  including stock-based compensation.  However, any
action in connection with the salary of the chief executive  officer is reviewed
and  approved  by the  Board of  Directors  after a  recommendation  by the MD&C
Committee.  See "Meetings and  Committees of the Board of Directors - Management
Development and Compensation Committee."

     CompX's executive  compensation  system generally consists of three primary
components:  salary, annual variable compensation and stock-based  compensation,
including  stock options,  restricted  stock and/or stock  appreciation  rights.
Through the use of the foregoing, the MD&C Committee seeks to achieve a balanced
compensation  package that will attract and retain high quality key  executives,
appropriately  reflect each such  executive  officer's  individual  performance,
contributions,  and general market value, and provide further  incentives to the
executive  officers to  maximize  annual  operating  performance  and  long-term
stockholder value.

Annual Salaries

     Base salaries for executive  officers of CompX have been  established  on a
position-by-position basis. The chief executive officer conducts annual internal
reviews of executive  officer  salary levels other than his own in an attempt to
rank salary and job value to each  position.  The chief  executive  officer then
makes  recommendations  on salaries to the MD&C  Committee.  The MD&C  Committee
reviews  the chief  executive  officer's  recommendations  regarding  changes in
salaries  for  executive  officers  other  than  himself.  When  recommendations
regarding changes in salary levels are made by the chief executive officer,  the
MD&C  Committee  may take  such  actions,  including  any  modifications  to the
recommendation,  as it deems appropriate. If the MD&C Committee decides a change
in the salary of the chief  executive  officer is warranted,  the MD&C Committee
will  make  the  recommendation  to the  Board  of  Directors  and the  Board of
Directors  may  take  such  actions,   including   any   modifications   to  the
recommendation,  as it deems appropriate. In each case the determinations of the
MD&C Committee and the Board of Directors, as applicable, may be based primarily
on a subjective  evaluation of past and potential future individual  performance
and contributions and alternative  opportunities  that might be available to the
executives  in  question.  The MD&C  Committee  or the  Board of  Directors,  as
applicable,   may  also  review   compensation  data  from  companies  employing
executives in positions  similar to those whose  salaries were being reviewed as
well as market  conditions  for  executives  in  general  with  similar  skills,
background and performance levels, both inside and outside of CompX's businesses
(such companies may include companies  contained in the peer group index plotted
on the  Performance  Graph  following  this report),  and other  companies  with
similar financial and business  characteristics as CompX, or where the executive
in question has similar responsibilities.

     The MD&C  Committee  based its actions  regarding  executive  officer  1999
salaries  primarily  upon the chief  executive  officer's  recommendations  with
regard to all  executive  officers  other than himself and its general  business
knowledge.  In 1999,  no  specific  survey or study was  utilized to make salary
determinations.  The MD&C  Committee  approved a 1999  salary  increase  for Mr.
Ronald J. Simmons from $123,300 annually to $150,000 annually due to an increase
in his  responsibilities.  No action was taken with respect to the 1999 salaries
of any of the other executive officers of CompX.

Annual Variable Compensation

     Awards  under the  variable  compensation  plan  constitute  a  significant
portion of an executive's  potential  annual cash  compensation  (between 0% and
150% of salary for the chief executive officer and certain executive  officers).
Awards  are  based on CompX  and/or  business  units of CompX  achieving  annual
predetermined  operating income goals. CompX's management makes  recommendations
to the Board of Directors regarding the operating income plan for the year after
reviewing  market  conditions  and  CompX's  operations,  competitive  position,
marketing  opportunities,  and strategies for maximizing financial  performance.
The Board of Directors approves this  recommendation with modifications it deems
appropriate.  Based on the business plan for the year,  the MD&C  Committee sets
CompX's and its business units'  operating income goals at three levels that are
designed to help focus CompX's executives on achieving superior annual operating
results in light of existing conditions: a threshold level, which is the minimum
operating income level for any award to be made under the variable  compensation
plan (the "Minimum  Level"),  a target level (the "Target  Level") and a maximum
level (the "Maximum Level"). The variable compensation plan, in combination with
salary,  is  designed  to  result  in  executive  officers  and  other  eligible
participants  receiving annual cash compensation below competitive  compensation
levels if the Minimum Level is not achieved.

     Pursuant to the variable  compensation  plan, if operating  income is below
the Minimum  Level,  no variable  compensation  is paid. If the Minimum Level is
met, executive officers are eligible to receive variable  compensation  payments
that in 1999 ranged  between 20% and 50% of salary,  depending on the executive.
If the Target Level is reached, the range of variable  compensation  payments is
higher,  and in 1999  ranged  between 30% and 100% of salary,  depending  on the
executive. If the Maximum Level is reached or exceeded,  executives are eligible
to receive the highest variable compensation  payments, and in 1999 the range of
payments for which  executives were eligible was between 40% and 150% of salary,
depending on the executive.

     As a result of CompX  achieving  1999  operating  income  below the Minimum
Level,  in the first  quarter of 2000 the MD&C  Committee  awarded  no  variable
compensation to the chief executive officer and the chief financial officer. The
1999 variable compensation of each of the other executive officers, however, was
partially based on a respective  business unit of CompX that achieved  operating
income above one of the unit's operating income goals. Accordingly, in the first
quarter of 2000 the MD&C Committee awarded a variable compensation award to each
such executive  officer based on the achieved  operating income goal of the unit
to which such executive officer's variable compensation was partially based. The
1999 awards under the variable compensation plan to the named executive officers
are set forth in the bonus  column in the Summary  Compensation  Table set forth
above.

     Apart from the variable  compensation  plan,  the MD&C  Committee may award
other bonuses  outside of the variable  compensation  plan as the MD&C Committee
deems  appropriate  from time to time  under its  general  authority  or under a
separate discretionary plan. The MD&C Committee did not award such other bonuses
to executive officers, including the chief executive officer, in 1999.

Stock-Based Compensation

     The 1997 Plan supports the goal of maximizing  long-term  stockholder value
by  providing  for  stock-based  compensation,  the  value of which is  directly
related to increases in stockholder  value.  Stock option grants, in particular,
are considered a significant  element of CompX's total compensation  package for
the chief executive officer and the other executive  officers of CompX. The MD&C
Committee  believes that  compensation  linked to stock price  performance helps
focus the  executives'  attention on management of CompX from the  stockholders'
perspective.

     Stock  option  grants  are  intended  to  provide  incentives  to  increase
stockholder value in the future and to reward past performance by the executive.
In 1999,  the MD&C Committee  reviewed  recommendations  by the chief  executive
officer regarding stock option grants to executive officers other than the chief
executive  officer.  The MD&C  Committee  granted  stock  options  to  executive
officers,  other than the chief executive officer,  based on the chief executive
officer's recommendations. The chief executive officer based his recommendations
on  a  subjective   evaluation   regarding  each  executive's   performance  and
responsibilities.   In  1999,  the  chief  executive  officer  included  in  his
recommendations  regarding the number of options to be granted to each executive
officer, other than the chief executive officer, the amount and terms of options
already  held by such  officers.  The MD&C  Committee  did not  grant  the chief
executive  officer any stock options in 1999. Stock options granted to executive
officers  in 1999 are  reported  in the  Option  Grants in 1999  table set forth
above.

     To help assure a focus on long-term  creation of stockholder value, in 1999
the MD&C Committee  granted stock options with a term of ten years that vest 20%
on each of the first five  anniversaries  of the stock  option's  date of grant.
Although permitted under the 1997 Plan, the MD&C Committee in 1999 did not grant
any restricted stock, stock appreciation rights or other equity-based awards.

Tax Code Limitation on Executive Compensation Deductions

     In 1993,  Congress  amended  the  Internal  Revenue  Code to  impose a $1.0
million  deduction limit on compensation paid to the chief executive officer and
the four other most highly  compensated  executive officers of public companies,
subject to certain  transition  rules and exceptions for  compensation  received
pursuant to non-discretionary performance-based plans approved by such company's
shareholders.  It is CompX's  general policy to structure the  performance-based
portion of the  compensation of its executive  officers in a manner that permits
CompX to deduct fully such compensation.

     The  foregoing  report is submitted  by the  following  individuals  in the
capacities indicated:

        Paul M. Bass, Jr.                         Ann Manix

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS

     Relationships  with  Related  Parties.  As  set  forth  under  the  caption
"Security  Ownership,"  Harold C.  Simmons,  through  Contran,  may be deemed to
control  CompX.  CompX and other entities that may be deemed to be controlled by
or  affiliated  with  Mr.  Simmons   sometimes  engage  in  (a)   intercorporate
transactions  such as guarantees,  management and expense sharing  arrangements,
shared fee arrangements, joint ventures, partnerships,  loans, options, advances
of funds on open account and sales,  leases and  exchanges of assets,  including
securities  issued  by  both  related  and  unrelated  parties  and  (b)  common
investment and acquisition strategies,  business combinations,  reorganizations,
recapitalizations,  securities  repurchases  and  purchases and sales (and other
acquisitions  and  dispositions)  of  subsidiaries,  divisions or other business
units,  which  transactions have involved both related and unrelated parties and
have included transactions that resulted in the acquisition by one related party
of a publicly held minority  equity  interest in another  related  party.  CompX
continuously  considers,  reviews and evaluates and understands that Contran and
related  entities  consider,  review  and  evaluate  transactions  of  the  type
described  above.  Depending upon the business,  tax and other  objectives  then
relevant,  it is  possible  that  CompX  might be a party to one or more of such
transactions  in the  future.  In  connection  with these  activities  CompX may
consider  issuing   additional   equity   securities  or  incurring   additional
indebtedness.   CompX's  acquisition   activities  may  in  the  future  include
participation in the acquisition or restructuring  activities conducted by other
companies that may be deemed to be controlled by Mr.  Simmons.  It is the policy
of CompX to engage in transactions with related parties on terms, in the opinion
of CompX,  no less  favorable  to CompX than could be  obtained  from  unrelated
parties.

     No  specific   procedures  are  in  place  that  govern  the  treatment  of
transactions  among CompX and its related  entities,  although such entities may
implement  specific  procedures as appropriate for particular  transactions.  In
addition,  under  applicable  principles  of law, in the absence of  stockholder
ratification  or  approval  by  directors  who  may  be  deemed   disinterested,
transactions  involving  contracts  among companies under common control must be
fair  to  all  companies  involved.  Furthermore,  directors  and  officers  owe
fiduciary  duties of good  faith and fair  dealing  to all  stockholders  of the
companies for which they serve.

     Intercorporate  Services Agreements.  Under the Valhi ISA, Valhi renders or
provides for certain management,  financial and administrative services to CompX
on a fee  basis.  Such fees are based  upon  estimates  of time  devoted  to the
affairs of CompX by individual Valhi employees and the salaries of such persons.
CompX paid Valhi fees of $324,000 for services  rendered  under the Valhi ISA in
1999. In addition,  Valhi charged CompX for the out-of-pocket  costs incurred in
rendering   such   services.   The  Valhi  ISA   automatically   extends   on  a
quarter-to-quarter  basis,  subject to  termination  by either party pursuant to
written  notice 30 days  prior to a  quarter-end,  and may be  amended by mutual
agreement.

     Under the ISA between  CompX and NL (the "NL ISA"),  NL makes  available to
CompX on a fee basis  certain  accounting  and  internal  auditing  services and
occupancy and related  office  services for CompX's  offices in Houston,  Texas.
Such fees are based upon  estimates of NL's costs of providing  such services to
CompX.  CompX paid NL fees of $173,000 for such  services  rendered in 1999.  In
addition,  NL charged CompX for the  out-of-pocket  costs  incurred in rendering
such services.  The NL ISA automatically extends on a quarter-to-quarter  basis,
subject to  termination by either party pursuant to written notice 30 days prior
to a quarter-end, and may be amended by mutual agreement.

     Insurance  Brokerage  Commissions.   NL  Insurance  Ltd.  of  Vermont  ("NL
Insurance"),  Valmont  and EWI RE,  Inc.  ("EWI")  provide or broker  certain of
CompX's  insurance  policies.  NL Insurance is a wholly owned captive  insurance
company of  Tremont.  Valmont is a wholly  owned  captive  insurance  company of
Valhi.  Parties  related to Contran own 90% of the  outstanding  common stock of
EWI,  and a  son-in-law  of Harold C.  Simmons  manages the  operations  of EWI.
Consistent  with insurance  industry  practices,  NL Insurance,  Valmont and EWI
receive  commissions  from the insurance and  reinsurance  underwriters  for the
policies that they provide or broker.  During 1999,  CompX and its  subsidiaries
paid  approximately  $431,000 for policies provided or brokered by NL Insurance,
Valmont and/or EWI. These amounts principally  included payments for reinsurance
and  insurance  premiums  paid to unrelated  third  parties,  but also  included
commissions  paid to NL  Insurance,  Valmont  and EWI. In CompX's  opinion,  the
amounts that CompX and its  subsidiaries  paid for these insurance  policies are
reasonable  and  similar to those they could  have  obtained  through  unrelated
insurance companies and/or brokers.  CompX expects that these relationships with
NL Insurance, Valmont and EWI will continue in 2000.

                                  OTHER MATTERS

     The Board of Directors  knows of no other  business  that will be presented
for consideration at the Meeting.  If any other matters properly come before the
Meeting,  the persons  designated as agents in the enclosed proxy card or voting
instruction  form  will vote on such  matters  in  accordance  with  their  best
judgment.

                         INDEPENDENT PUBLIC ACCOUNTANTS

     The  firm  of   PricewaterhouseCoopers   LLP  served  as  CompX's   primary
independent  public  accountants  for the year ended December 31, 1999.  CompX's
audit  committee has  appointed  PricewaterhouseCoopers  LLP as CompX's  primary
independent   public   accountants  for  the  year  ending  December  31,  2000.
Representatives  of  PricewaterhouseCoopers  LLP are not  expected to attend the
Meeting.
