                                 PROXY STATEMENT

                         ------------------------------

                               GENERAL INFORMATION

     This proxy statement and the accompanying  proxy card or voting instruction
form are being furnished in connection  with the  solicitation of proxies by and
on  behalf of the  board of  directors  (the  "Board  of  Directors")  of Kronos
Worldwide,  Inc., a Delaware  corporation ("Kronos  Worldwide"),  for use at the
2004 Annual Meeting of Stockholders of Kronos  Worldwide to be held on Thursday,
May 20, 2004 and at any adjournment or postponement thereof (the "Meeting"). The
accompanying  Notice of Annual Meeting of Stockholders (the "Notice") sets forth
the time, place and purposes of the Meeting.  The Notice,  this proxy statement,
the accompanying  proxy card or voting  instruction form and Kronos  Worldwide's
Annual Report to Stockholders,  which includes Kronos  Worldwide's Annual Report
on Form 10-K for the fiscal year ended December 31, 2003 (the "Annual  Report"),
are first being mailed to the holders of Kronos  Worldwide's  common stock,  par
value  $0.01 per share  ("Common  Stock"),  on or about April 16,  2004.  Kronos
Worldwide's  principal  executive  offices are located at Three Lincoln  Centre,
5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697.

                  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 29, 2004 (the "Record  Date").  As of the Record  Date,  there
were  48,943,049  shares of Common Stock issued and  outstanding.  Each share of
Common  Stock  entitles  its holder to one vote on all matters to be acted on at
the Meeting.  The presence,  in person or by proxy, of the holders of a majority
of the shares of Common  Stock  entitled to vote at the Meeting is  necessary to
constitute a quorum for the conduct of business at the Meeting. Shares of 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.

     If a  quorum  is  present,  a  plurality  of the  affirmative  votes of the
outstanding  shares of Common Stock  represented and entitled to be voted at the
Meeting,  is  necessary  to  elect  each  director  of  Kronos  Worldwide.   The
accompanying  proxy  card  or  voting  instruction  form  provides  space  for a
stockholder  to withhold  authority to vote for any 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. However,
since director  nominees need only receive the vote of a plurality of the shares
represented  and  entitled  to  vote  at the  Meeting,  a vote  withheld  from a
particular nominee will not affect the election of such nominee.

     Except as applicable  laws may otherwise  provide,  if a quorum is present,
the approval of any other matter that may properly  come before the Meeting will
require  the  affirmative  vote of a  majority  of the  shares  represented  and
entitled  to vote at the  Meeting.  Shares  of  Common  Stock  that are voted to
abstain from any other  business  coming  before the Meeting and  broker/nominee
non-votes will not be counted as votes for or against any such other matter.

     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.



     EquiServe Trust Company N.A. or its successor  ("EquiServe"),  the transfer
agent and registrar for Kronos Worldwide 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 Common Stock giving the proxy  enclosed  with this
proxy  statement may revoke it at any time prior to the voting at the Meeting by
delivering  to EquiServe a written  revocation  of the proxy or 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.

     The Board of Directors is making this proxy solicitation.  Kronos Worldwide
will  pay all  expenses  related  to the  solicitation,  including  charges  for
preparing,  printing,  assembling and  distributing  all materials  delivered to
stockholders.  In addition to the solicitation by mail, directors,  officers and
regular  employees of Kronos  Worldwide  may solicit  proxies by telephone or in
person, for which such persons will receive no additional  compensation.  Kronos
Worldwide has retained The Altman Group, Inc. to aid in the distribution of this
proxy statement and related  materials at a cost Kronos  Worldwide  estimates at
$1,000.  Upon request,  Kronos  Worldwide 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 Common Stock that such entities
hold of record.

        NL'S DECEMBER 2003 DISTRIBUTION OF KRONOS WORLDWIDE COMMON STOCK

     Prior to December 8, 2003 (the "Distribution Date"), Kronos Worldwide was a
wholly owned subsidiary of NL Industries, Inc. ("NL"). On the Distribution Date,
NL distributed  approximately 48.8% of the outstanding shares of Common Stock to
its  shareholders on the basis of one share of Common Stock for every two shares
of NL common stock, par value $0.125 per share ("NL Common Stock"),  outstanding
as of the close of  business  on  November  17,  2003,  the record  date for the
distribution.  No  fractional  shares  of Kronos  Worldwide  common  stock  were
distributed. NL shareholders who would have otherwise been entitled to receive a
fractional share of Common Stock received cash in lieu of such fractional share.

                               CONTROLLED COMPANY

     NL,  Valhi,  Inc.  ("Valhi")  and  Tremont LLC  ("Tremont")  are the direct
holders of 50.5%,  32.8% and 10.6%,  respectively,  of the outstanding shares of
Common Stock as of the Record Date. Together, NL, Valhi and Tremont own 93.8% of
the outstanding  shares of Common Stock.  NL, Valhi and Tremont are each related
to Contran Corporation  ("Contran").  Harold C. Simmons may be deemed to control
NL, Valhi, Tremont and Contran.

     NL, Valhi and Tremont  have each  indicated  their  intention to have their
shares of Common Stock  represented  at the Meeting and voted "FOR" the election
of each of the  nominees  for  director of the Board of  Directors.  If NL 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.

     Because of the Common Stock  ownership  of NL,  Valhi and  Tremont,  Kronos
Worldwide is considered a controlled  company under the listing standards of the
New York Stock  Exchange  (the  "NYSE").  Pursuant to the listing  standards,  a
controlled  company may choose not to have a majority of independent  directors,
independent  compensation,  nominating  or corporate  governance  committees  or
charters  for  these  committees.  Kronos  Worldwide  has  chosen  not to have a
majority of  independent  directors or an  independent  nominating  or corporate
governance  committee.  The Board of Directors  believes  that the full Board of
Directors  best   represents   the  interests  of  all  of  Kronos   Worldwide's
stockholders and that it is appropriate for all matters that would be considered
by a nominating or corporate  governance  committee to be  considered  and acted
upon by the full  Board of  Directors.  Applying  the  requirements  of the NYSE
listing  standards,  the Board of  Directors  has  determined  that three of its
directors  are  independent  and  have  no  material  relationship  with  Kronos
Worldwide.  While the members of Kronos Worldwide's  management  development and
compensation committee (the "MD&C Committee") currently satisfy the independence
requirements of the NYSE listing  standards,  Kronos Worldwide has chosen not to
satisfy all of the NYSE listing  standards  for a  compensation  committee.  See
"Meetings and Committees of the Board of Directors" for more  information on the
committees of the Board of Directors.  See also  "Stockholder  Proposals for the
2005 Annual  Meeting"  for a  description  of Kronos  Worldwide's  policies  and
procedures for stockholder nominations of directors.

                                      -2-


                              ELECTION OF DIRECTORS

     The bylaws of Kronos  Worldwide  provide that the Board of Directors  shall
consist of one or more  members as  determined  by the Board of Directors or the
stockholders.  The Board of Directors  has currently set the number of directors
at six.  The  directors  elected at the Meeting  will hold office until the 2005
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 Kronos Worldwide 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.

     THE  BOARD  OF  DIRECTORS  RECOMMENDS  A VOTE  "FOR"  THE  ELECTION  OF THE

                MEETINGS AND COMMITTEES OF THE BOARD OF DIRECTORS

     On or after the Distribution  Date, the Board of Directors did not hold any
meetings  in 2003 but took  action by  unanimous  written  consent  in lieu of a
meeting on one  occasion.  It is Kronos  Worldwide's  policy that each  director
attend  its  annual  meeting  of  stockholders,  which  will  generally  be held
immediately before the annual meeting of the Board of Directors.

     The Board of  Directors  has  established  and  delegated  authority to the
following two standing committees.

          Audit Committee.  The audit committee  assists the Board of Directors'
     oversight   responsibilities  relating  to  the  financial  accounting  and
     reporting  processes  and  auditing  processes  of  Kronos  Worldwide.  The
     responsibilities  of the audit committee are more specifically set forth in
     the audit committee charter attached as Appendix A to this proxy statement.
     Applying the requirements of the NYSE listing  standards and Securities and
     Exchange  Commission  ("SEC")  regulations,  as  applicable,  the  Board of
     Directors has determined that

          -    each member of the audit  committee is  financially  literate and
               independent  and  has  no  material   relationship   with  Kronos
               Worldwide; and
          -    Mr.  Cecil  H.  Moore,  Jr.  is the  "audit  committee  financial
               expert."

     No member of the audit  committee  serves on more than three public company
     audit  committees.  For  further  information  on the  role  of  the  audit
     committee,  see "Audit Committee  Report." The current members of the audit
     committee are R. Gerald Turner  (chairman),  Cecil H. Moore, Jr. and George
     E. Poston.  The audit committee did not hold any meetings in 2003. Prior to
     the Distribution Date, NL's audit committee  performed the functions of the
     Kronos Worldwide audit committee.

          Management  Development  and  Compensation  Committee.  The  principal
     responsibilities  of the MD&C  Committee are to review and approve  certain
     matters involving executive  compensation;  to take action or to review and
     approve certain matters regarding Kronos Worldwide's employee benefit plans
     or programs;  to  administer  and grant awards under the Kronos  Worldwide,
     Inc. 2003 Long-Term  Incentive Plan (the "2003 Plan");  to approve  certain
     annual  incentive  compensation  awards;  and to review and administer such
     other  compensation  matters as the Board of Directors may direct from time
     to time. The Board of Directors has determined that each member of the MD&C
     Committee is independent by applying the  requirements  of the NYSE listing
     standards.  For further information on the role of the MD&C Committee,  see
     "Report  On  Executive  Compensation."  The  current  members  of the  MD&C
     Committee are R. Gerald Turner  (chairman)  and George E. Poston.  The MD&C
     Committee  did not hold any  meetings  in 2003.  Prior to the  Distribution
     Date, NL's management  development and compensation committee performed the
     functions of the MD&C Committee. The MD&C Committee does not have a written
     charter.

     The Board of  Directors  is expected  to elect the members of the  standing
committees at the Board of Directors  annual meeting  immediately  following the
Meeting.  The Board of Directors has  previously  established,  and from time to
time may  establish,  other  committees  to  assist it in the  discharge  of its
responsibilities.

Foreclosure by the lender on this pledge in the event of Valhi's  default on the
loan, which Valhi has advised Kronos Worldwide is unlikely,  may at a subsequent
date result in a change in control of NL.

                              AND OTHER INFORMATION

     Compensation  of Directors.  Directors of Kronos  Worldwide did not receive
any compensation for 2003. In 2004,  directors are expected to receive an annual
retainer of $20,000,  paid in quarterly  installments,  plus a fee of $1,000 per
day for  attendance  at  meetings  and at a daily rate ($125 per hour) for other
services  rendered on behalf of the Board of  Directors  or its  committees.  In
addition, directors will receive an annual retainer of $2,000, paid in quarterly
installments, for each committee on which they serve. If any director dies while
serving on the Board of Directors,  his or her designated  beneficiary or estate
will be entitled to receive a death benefit equal to the annual retainer then in
effect.  Kronos  Worldwide  reimburses  its  directors for  reasonable  expenses
incurred in attending meetings and in the performance of other services rendered
on behalf of the Board of Directors or its committees.

     On the day of the Meeting,  each director is expected to receive a grant of
shares of Common  Stock as  determined  by the  following  formula  based on the
closing price of a share of Common Stock on the date of the Meeting.

(1)  Other than Drs. Fiand and Wigdor,  Kronos  Worldwide's  executive  officers
     provided  their  services to Kronos  Worldwide  during  2003  pursuant to a
     Services Agreement between NL, Kronos Worldwide and KII dated as of January
     1, 1995 and  amended  as of April 1, 2002 (the "NL  ISA").  Other  than Mr.
     Simmons, the charges for such executive officers' services under the NL ISA
     for 2003 to  Kronos  Worldwide  were  not  specifically  identifiable  to a
     particular  executive  officer or did not exceed $100,000.  NL's charges to
     Kronos  Worldwide  under the NL ISA for the  services  of Robert D.  Hardy,
     Kronos Worldwide's  former chief financial  officer,  were not specifically
     identifiable  to his  services.  However,  KII  paid  Mr.  Hardy a bonus of
     $250,000 in 2001 outside of the NL ISA for  services Mr. Hardy  rendered to
     KII.  See  "Certain  Relationships  and Related  Transactions."  Mr.  Hardy
     resigned as chief financial officer of Kronos Worldwide  effective July 28,
     2003.

(2)  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.

(3)  Other  annual  compensation  for  each  of  the  named  executive  officers
     represents  perquisites  to the extent  such  amounts  are  required  to be
     reported pursuant to SEC rules.

(4)  For all of 2003, Harold C. Simmons was an employee of Contran. He became an
     executive  officer of Kronos  Worldwide  as of August 6,  2003.  The amount
     shown in the table as salary for him in 2003  represents the portion of the
     fees Kronos  Worldwide and its  subsidiaries  paid to NL pursuant to the NL
     ISA that  relates to  services  he  rendered  to Kronos  Worldwide  and its
     subsidiaries in 2003.

(5)  Dr. Fiand receives his cash compensation in euros. Kronos Worldwide reports
     these  amounts  in the table  above in U.S.  dollars  based on the  average
     exchange  rate for each of 2003,  2002  and 2001 of  $1.1212,  $0.9360  and
     $0.8957 per (euro)1.00, respectively.

(6)  Represents options to purchase shares of NL Common Stock. Upon exercise, NL
     will bill Kronos Worldwide the difference  between the fair market value of
     the shares issued upon exercise and the aggregate  exercise  price for such
     shares.

                                      -12-


(7)  In July 2003, Dr. Wigdor  resigned as Kronos  Worldwide's  chief  executive
     officer  and elected to receive  early  retirement  benefits.  Prior to his
     resignation, Dr. Wigdor was an executive officer of NL and Kronos Worldwide
     and  devoted all of his  business  time to Kronos  Worldwide.  Accordingly,
     prior to his resignation  Kronos Worldwide paid, accrued or was charged for
     all  of  Dr.  Wigdor's  compensation.  Dr.  Wigdor  currently  serves  as a
     consultant to Kronos Worldwide with ongoing  management  involvement in the
     TiO2 operations  conducted by Kronos Worldwide.  Of the amount shown in the
     table as the 2003 salary for Dr.  Wigdor,  $495,833  represents  the salary
     Kronos  Worldwide  paid him for his 2003 services  while he was an employee
     and $420,000  represents the amount Kronos  Worldwide paid him for his 2003
     services  while he was a  consultant.  The amount shown in the table as the
     2003 bonus for Dr. Wigdor represents  amounts Kronos Worldwide paid him for
     his 2003  services  while he was a consultant  that are  comparable to 2003
     bonus payments. See "-- Wigdor Compensatory Arrangement."

(8)  Amounts  Kronos  Worldwide  paid  Dr.  Wigdor  pursuant  to  NL's  variable
     compensation plan,  including,  in certain instances,  discretionary  bonus
     amounts.

(9)  These amounts represent accruals on Dr. Wigdor's deferred compensation that
     exceeded 120% of the applicable federal long-term interest rate.

(10) As shown below,  all other  compensation  for 2003,  2002, and 2001 for Dr.
     Wigdor  consisted of (i) matching  contributions  Kronos  Worldwide made or
     accrued  pursuant  to the  savings  feature  of the NL savings  plan,  (ii)
     retirement  contributions  Kronos Worldwide made or accrued pursuant to the
     NL savings plan,  (iii) life insurance  premiums Kronos  Worldwide paid and
     (iv) amounts  Kronos  Worldwide  paid under the NL  Supplemental  Executive
     Retirement Plan (the "SERP").

     In 2001, NL amended the SERP to provide for the distribution of the accrued
     balance in each SERP  participant's  account and the payment of future SERP
     benefits to  participants  as accrued,  thus  reducing  Kronos  Worldwide's
     interest costs. In connection with the amendment,  in 2001 Kronos Worldwide
     paid $1,761,661 to Dr. Wigdor, which represented the accrued vested balance
     in his SERP account with interest.  These accrued  amounts were  previously
     reported as compensation in the years accrued.

                                      -13-


     No Grants of Stock Options or Stock  Appreciation  Rights.  Neither  Kronos
Worldwide  nor any of its parent or  subsidiary  corporations  granted any stock
options or stock  appreciation  rights ("SARs") to the named executive  officers
during 2003.

(1)  During 2003, Robert D. Hardy received 12,000 shares of NL Common Stock upon
     the exercise of his stock options and realized an aggregate value from such
     exercises  of $56,212.  The amount he realized  upon the  exercise of stock
     options is based on the  difference  between  the  closing  sales price per
     share of NL Common Stock on the day of exercise and the exercise  price per
     share.  At December 31, 2003, Mr. Hardy held  exercisable  stock options to
     purchase 50,000 shares of NL Common Stock and  unexercisable  stock options
     to  purchase  48,000  shares of NL Common  Stock.  Based on the  difference
     between the exercise price of his  individual  stock options and the $11.70
     per share closing sales price of NL Common Stock on December 31, 2003,  the
     value  of Mr.  Hardy's  exercisable  and  unexercisable  stock  options  to
     purchase NL common stock was $31,424 and $124,612, respectively.

(2)  The value is based on the  difference  between  the  exercise  price of the
     individual stock options and the closing sales price per share of NL Common
     Stock on December 31, 2003 of $11.70.

     Pension Plans. The Retirement  Program of NL Industries,  Inc. for its U.S.
employees (the "Pension Plan") provides lifetime retirement benefits to eligible
employees.  In 1996, NL approved the suspension of all future accruals under the
salaried component of the Pension Plan.  Following his resignation in July 2003,
Dr. Wigdor  elected to receive his  retirement  benefits at an early  retirement
age. He began receiving a monthly payment amount of $2,428 in August 2003, which
will  continue  for the  remainder of his life.  The  estimated  accrued  annual
benefit payable under the Pension Plan upon retirement at normal  retirement age
for Mr. Hardy is $12,348.

     Dr.  Fiand  is  eligible  to  receive  his  pension  through  KII's  German
operations   ("Kronos   Germany")  through  the  Bayer   Pensionskasse  and  the
Supplemental  Pension Promise. All of KII's employees in Germany (including wage
earners) who have  contributed  for five years and are less than 55 years of age
are covered by the Bayer Pensionskasse. Each employee contributes 2% of eligible
earnings  excluding  bonus,  up to  the  social  security  contribution  ceiling
(currently  (euro)61,200) and the Bayer Pensionskasse  provides a benefit of 44%
of  such  employee's  accumulated  contributions  (with  a  minimum  benefit  of
approximately  (euro)13 per month). The Supplemental Pension Promise also covers
all of KII's  employees  in Germany  who have  completed  ten years of  service.
Kronos  Germany  accrues  11.25%  of  participants'   eligible  annual  earnings
excluding bonus in excess of the social security  contribution  ceiling, up to a
maximum of  (euro)106,900.  The Supplemental  Pension Promise provides an annual
retirement  benefit of 20% of all accruals made by Kronos Germany.  Benefits for
both plans are payable upon  retirement  and the attainment of ages specified in
the plans. No amounts were paid or distributed under these plans to Dr. Fiand in
2003. The estimated  accrued annual  benefit  payable upon normal  retirement at
normal retirement age for Dr. Fiand is (euro)25,991.

                                      -14-


     Wigdor Compensatory Arrangement. Concurrently with his resignation as chief
executive  officer of Kronos  Worldwide in July 2003,  Dr. Wigdor entered into a
consultancy  arrangement  with Kronos  Worldwide  pursuant  to which Dr.  Wigdor
provides ongoing  management  involvement in Kronos Worldwide's TiO2 operations.
Dr. Wigdor received  $461,000 on August 1, 2003 and monthly  payments of $84,000
beginning on August 1, 2003. On February 1, 2004, Dr. Wigdor  received a payment
under the arrangement of $461,000 based on Kronos Worldwide having achieved 2003
segment profit (as Kronos  Worldwide  defines that term internally) of in excess
of $130 million. Beginning in 2004, Dr. Wigdor will receive annual discretionary
bonuses that are no less than the average bonus paid to the three  executives of
NL and Kronos Worldwide combined receiving the highest paid bonuses for 2004 and
2005,   respectively,   excluding  NL's  chief  executive  officer.   Under  the
consultancy  arrangement,  as  amended in  February  2004,  if Kronos  Worldwide
terminates the  consultancy  arrangement  prior to December 31, 2006, Dr. Wigdor
will receive twelve months  compensation and medical and dental coverage through
December 31, 2006 and, if terminated in 2004 or after, a pro-rata portion of his
discretionary   bonus  for  the  year  in  which  the  termination  occurs.  The
arrangement  provides Dr.  Wigdor  various other  benefits,  such as medical and
dental  benefits and office and  secretarial  support at Kronos  Worldwide's New
Jersey office.

                       CODE OF BUSINESS CONDUCT AND ETHICS

     Kronos  Worldwide  has adopted a code of  business  conduct and ethics that
applies  to  all  of  Kronos  Worldwide's  directors,  officers  and  employees,
including Kronos Worldwide's  principal  executive officer,  principal financial
officer,  principal  accounting officer and controller.  Any person may obtain a
copy of the  code,  without  charge,  by  sending a  written  request  to Kronos
Worldwide's corporate secretary at Kronos Worldwide, Inc., Three Lincoln Centre,
5430 LBJ  Freeway,  Suite  1700,  Dallas,  Texas  75240-2697.  Only the Board of
Directors may amend the code.  The code will be available on Kronos  Worldwide's
website at  www.kronostio2.com  in accordance with NYSE listing standards.  Only
Kronos  Worldwide's audit committee or other committee of the Board of Directors
with  specific  delegated  authority  may  grant a waiver  of the  code.  Kronos
Worldwide  will disclose  amendments  to, or waivers of, the code as required by

                         CORPORATE GOVERNANCE GUIDELINES

     Kronos Worldwide intends to adopt corporate governance guidelines that will
comply with the NYSE  listing  standards.  Kronos  Worldwide  will also make the
guidelines  and its audit  committee  charter  available  on Kronos  Worldwide's

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section  16(a) of the  Securities  Exchange  Act of 1934,  as amended  (the
"Exchange Act"), requires Kronos Worldwide's  executive officers,  directors and
persons who own more than 10% of a registered class of Kronos Worldwide's equity
securities  to file  reports  of  ownership  with the SEC,  the NYSE and  Kronos
Worldwide.  Based  solely  on the  review  of  the  copies  of  such  forms  and
representations by certain reporting persons, Kronos Worldwide believes that for
2003 its executive  officers,  directors and 10% stockholders  complied with all
applicable filing requirements under Section 16(a).

                                      -16-


                        REPORT ON EXECUTIVE COMPENSATION

     During 2003,  Kronos  Worldwide  paid certain  amounts to NL for  executive
management  services pursuant to the NL ISA,  including the advisory services of
Mr. Harold C. Simmons. Before the changes Kronos Worldwide made to its executive
management in 2003, Kronos Worldwide's executive officers (with the exception of
Dr. Lawrence A. Wigdor) provided their services to Kronos Worldwide  pursuant to
the NL ISA.  Following the  management  changes,  Kronos  Worldwide's  executive
officers  (other than Dr. Ulfert Fiand and Mr. John A. St. Wrba)  provided their
services to Kronos  Worldwide  indirectly  pursuant  to the 2003  intercorporate
services agreement between NL and Contran (the "2003 Contran/NL ISA"). Under the
Contran/NL ISA,  Contran provided certain services to NL, including the advisory
services  of Mr.  Harold C.  Simmons,  certain of which were for the  benefit of
Kronos Worldwide.

     In  considering  the NL ISA, the Company  considered  the overall fee to be
charged to Kronos Worldwide under the NL ISA for the services provided to Kronos
Worldwide.  No  specific  formulas,  guidelines  or  comparable  positions  were
considered  in  determining  the amount of such fee,  nor was there any specific
relationship  between Kronos  Worldwide's  current or future performance and the
level of such fee. In 2003, Kronos Worldwide did not pay any additional  amounts
to NL under the NL ISA for services  provided to Kronos Worldwide  indirectly by
Contran.  Certain of the amounts  paid by Kronos  Worldwide in 2003 under the NL
ISA were  identifiable  to a specific  Kronos  Worldwide  executive  officer and
others were not. See "Certain Relationships and Related Transactions."

     In 2003, the Management  Development and Compensation  Committee of NL (the
"NL MD&C Committee")  administered  matters regarding the compensation of Kronos
Worldwide's  former chief executive  officer ("CEO"),  who was also an executive
officer of NL, and Dr. Fiand. Historically, Kronos Worldwide's cash compensation
system with respect to its  executive  officers was part of the NL  compensation
system,  and  generally  consisted  of two primary  components:  base salary and
annual  variable  compensation  provided by the NL Variable  Compensation  Plan.
Through the use of the foregoing and other incentive compensation  arrangements,
the NL MD&C  Committee  sought to achieve a balanced  compensation  package that
would 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 officers to maximize annual
operating performance and long-term shareholder value.

     In 2003, the NL MD&C Committee  reviewed and acted on the recommendation of
the former NL CEO  regarding a change in the base salaries for certain of Kronos
Worldwide's  executive  officers,  including Kronos  Worldwide's former CEO. The
former NL CEO made this  recommendation  after consultation with the chairman of
the  board  of NL.  This  recommendation  and  the NL MD&C  Committee's  actions
regarding base salaries in 2003 were 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.
In 2003, the former Kronos  Worldwide  CEO's base salary was not changed nor set
based on any specific relationship to Kronos Worldwide's financial performance.

     During 2003, the NL MD&C Committee established awards under the NL Variable
Compensation Plan for the former Kronos Worldwide CEO and the executive officers
of Kronos  Worldwide  serving at the time. The awards were  contingent on Kronos
Worldwide's  achieving  certain 2003 operating  income goals.  The former Kronos
Worldwide  CEO was not entitled to a payout  under the NL Variable  Compensation
Plan  due to his  retirement  in July  2003;  however,  in  connection  with his
retirement he received a payment comparable to the amount he would have received
under  the NL  Variable  Compensation  Plan.  No  executive  officer  of  Kronos
Worldwide,  other  than Dr.  Fiand  and Mr.  St.  Wrba,  received  any  variable
compensation award for 2003 under the NL Variable Compensation Plan. Dr. Fiand's
award is disclosed under the bonus column of the Summary Compensation Table.

     In 2003, NL's MD&C Committee administered matters regarding the stock-based
compensation of Kronos Worldwide's  executive officers;  however, no stock-based
awards were made.  In 2004,  the Kronos  Worldwide  MD&C  Committee  administers
matters regarding the stock-based  compensation of Kronos Worldwide's  executive
officers.  The Kronos  Worldwide MD&C  Committee  does not currently  anticipate
granting stock-based  compensation to anyone in 2004 other than annual grants of
stock to Kronos  Worldwide's  directors,  including the chief executive officer,
for their services as directors.

                                      -17-


     Section  162(m) of the Code  generally  disallows a tax deduction to public
companies  for  compensation  over  $1.0  million  paid to the  company's  chief
executive officer and four other most highly compensated  executive officers. It
is Kronos Worldwide's general policy to structure the performance-based  portion
of the  compensation of its executive  officers in a manner that enhances Kronos
Worldwide's ability to deduct fully such compensation.

     The following individuals,  in the capacities indicated,  hereby submit the
foregoing report.

          R. Gerald Turner                     George E. Poston

                     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 Kronos Worldwide. Kronos Worldwide 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,  tax sharing agreements, 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 equity  interest in another
related party. Kronos Worldwide 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 and restrictions under the indentures and other agreements,  it is
possible  that  Kronos  Worldwide  might  be a  party  to one or  more  of  such
transactions in the future. In connection with these activities Kronos Worldwide
may consider  issuing  additional  equity  securities  or  incurring  additional
indebtedness.  Kronos  Worldwide's  acquisition  activities  may in  the  future
include  participation in acquisition or restructuring  activities  conducted by
other  companies that may be deemed to be controlled by Mr.  Simmons.  It is the
policy of Kronos  Worldwide to engage in  transactions  with related  parties on
terms, in the opinion of Kronos Worldwide, no less favorable to Kronos Worldwide
than could be obtained from unrelated parties.

     Certain directors or executive officers of Contran,  CompX,  Keystone,  NL,
TIMET  or  Valhi  also  serve as  directors  or  executive  officers  of  Kronos
Worldwide.  Such relationships may lead to possible conflicts of interest. These
possible  conflicts  of  interest  may arise from the duties of loyalty  owed by
persons  acting  as  corporate  fiduciaries  to  two  or  more  companies  under
circumstances  in which such companies may have adverse  interests.  No specific
procedures are in place that govern the treatment of  transactions  among Kronos
Worldwide  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 owe  fiduciary  duties of good faith and fair
dealing to all stockholders of the companies for which they serve.

     Intercorporate  Services  Agreements.   Kronos  Worldwide  is  a  party  to
intercorporate   services  agreements  ("ISAs")  with  various  related  parties
discussed below.  Under the ISAs,  employees of one company will provide certain
services,  including  executive officer services,  to the other company on a fee
basis.  Such  charges are based upon  estimates of the time devoted by employees
(or in certain  instances,  groups of employees) of the provider of the services
to the affairs of the recipient, and the compensation of such persons.

     Under  the  NL  ISA,  NL  provided   certain   management,   financial  and
administrative services to Kronos Worldwide and its subsidiaries on a fee basis.
Kronos Worldwide's intercorporate services fee expense related to the NL ISA was
$3.5 million in 2001 and $3.7 million in each of 2002 and 2003. Under the NL ISA
and  included  in the total fee NL  charged  Kronos  Worldwide  in 2001,  Kronos
Worldwide  paid  fees of  approximately  $1.4  million  for  tax and  controller
services, which included the amount Kronos Worldwide paid NL for the services of
Robert D. Hardy as tax director and controller of Kronos Worldwide. Under the NL
ISA and  included in the total fee NL charged  Kronos  Worldwide in each of 2002
and 2003,  Kronos  Worldwide paid fees of  approximately  $2.1 million for chief
financial, treasury, tax and controller services,  respectively,  which included
the amount Kronos  Worldwide  paid NL for the services of Robert D. Hardy.  NL's
charges to Kronos Worldwide under the NL ISA for the services Mr. Hardy provided
to Kronos Worldwide are not specifically identifiable to his services.  However,
KII  paid  Mr.  Hardy a bonus  of  $250,000  in 2001  outside  of the NL ISA for
services Mr. Hardy rendered to KII.

     Effective  November  6, 2003,  Kronos  Worldwide  entered  into an ISA with
Contran (the "Contran ISA"),  which ISA was amended as of January 1, 2004. Under
the Contran ISA, Contran provides  executive,  management,  financial,  internal
audit, accounting, tax, legal, insurance, risk management,  treasury,  aviation,
human resources,  technical,  consulting,  administrative  and other services as
required  from  time  to time  in the  ordinary  course  of  Kronos  Worldwide's
business.  These services include the services of certain of Kronos  Worldwide's
executive officers. The Contran ISA has an initial term that expires on December
31, 2004 and thereafter  automatically  extends on a  quarter-to-quarter  basis,
generally  subject to the  termination  by either  party  pursuant  to a written
notice delivered 30 days prior to the start of the next quarter. In 2004, Kronos
Worldwide expects to pay Contran $4.4 million for its services under the Contran
ISA. Kronos  Worldwide also pays director fees and expenses  directly to Messrs.
Glenn and Harold Simmons and Mr. Watson.

                                      -20-


     Loans Between Related Parties.  At December 31, 2002,  Kronos Worldwide had
loaned  $44.6  million to NL under the terms of a $55 million  revolving  credit
facility  entered into with NL during 2002. The loan bore interest at U.S. LIBOR
plus 1.75% (3.1% at December 31, 2002), with interest payable quarterly, and all
principal was due on December 31, 2005.  During the first six months of 2003, NL
repaid a net $19.7 million to Kronos  Worldwide.  In June 2003, Kronos Worldwide
distributed to NL the remaining $24.9 million of notes receivable from NL in the
form  of a  noncash  dividend.  The  revolving  credit  agreement  with  NL  was
terminated on June 30, 2003.

     At December 31, 2002,  Kronos  Worldwide had borrowed $44.6 million from NL
Environmental  Management Services, Inc., a majority owned subsidiary of NL ("NL
EMS"),  under the terms of a $55 million  revolving credit facility entered into
with NL EMS in 2002.  The loan bore  interest at U.S.  LIBOR plus 1.75% (3.1% at
December 31, 2002), with interest payable  quarterly,  and all principal was due
on December  31,  2005.  During the first six months of 2003,  Kronos  Worldwide
repaid this outstanding balance in full, and the revolving credit agreement with
NL EMS was terminated on June 30, 2003.

     On the Distribution Date,  immediately prior to NL's distribution of Kronos
Worldwide Common Stock, Kronos Worldwide  distributed a $200 million dividend to
NL in the form of a long-term  note  payable.  The $200 million  long-term  note
payable to NL is unsecured  and bears  interest at 9% per annum,  with  interest
payable quarterly and all principal due in 2010.

     From  time to time,  other  loans  and  advances  are made  between  Kronos
Worldwide and various related parties  pursuant to term and demand notes.  These
loans and advances are entered into  principally for cash  management  purposes.
When Kronos  Worldwide loans funds to related  parties,  the lender is generally
able to earn a higher  rate of return on the loan than the lender  would earn if
the funds were invested in other instruments. While certain of such loans may be
of a lesser credit quality than cash equivalent  instruments otherwise available
to Kronos Worldwide,  Kronos Worldwide believes that it has evaluated the credit
risks  involved,  and that those risks are reasonable and reflected in the terms
of the applicable loans. When Kronos Worldwide borrows from related parties,  it
is  generally  able to pay a lower  rate of  interest  than it  would  pay if it
borrowed from other parties.  Interest income on all such cash management  loans
to related parties was $0.7 million in 2003.  Interest  expense on all such cash
management loans from related parties was $1.9 million in 2003.

     Insurance Matters.  Contran and Kronos Worldwide  participate in a combined
risk  management  program.  Pursuant to the program,  Contran and certain of its
subsidiaries  and  affiliates,  including  Kronos  Worldwide  and certain of its
subsidiaries and affiliates,  purchase certain of their insurance  policies as a
group,  with the costs of the jointly owned policies being apportioned among the
participating  companies.  Tall Pines Insurance Company ("Tall Pines"),  Valmont
and EWI RE, Inc.  ("EWI") provide for or broker these insurance  policies.  Tall
Pines and Valmont are captive insurance companies wholly owned by Valhi, and EWI
is a  reinsurance  brokerage  firm wholly owned by NL. A son-in-law of Harold C.
Simmons serves as EWI's chairman of the board and chief marketing officer and is
compensated as an employee of EWI. Consistent with insurance industry practices,
Tall Pines,  Valmont and EWI receive  commissions from insurance and reinsurance
underwriters for the policies that they provide or broker.

     With respect to certain of such jointly  owned  insurance  policies,  it is
possible that unusually  large losses  incurred by one or more insureds during a
given  policy  period  could  leave the other  participating  companies  without
adequate  coverage under that policy for the balance of the policy period.  As a
result, Contran and certain of its subsidiaries or affiliates,  including Kronos
Worldwide and certain of its  subsidiaries  or  affiliates,  have entered into a
loss  sharing  agreement  under  which  any  uninsured  loss is  shared by those
entities who have submitted claims under the relevant  policy.  Kronos Worldwide
believes  the  benefits in the form of reduced  premiums  and  broader  coverage
associated  with  the  group  coverage  for  such  policies  justify  the  risks
associated with the potential for any uninsured loss.

                                      -21-


     During 2003, Contran and its related parties paid premiums of approximately
$16.7  million for  policies  Tall Pines or Valmont  provided  or EWI  brokered,
including  approximately  $7.2 million paid by Kronos  Worldwide  and  Louisiana
Pigment  Company,  L.P., a  partnership  of which Kronos  Worldwide and Huntsman
International  LLC each own 50%  ("LPC").  These  amounts  principally  included
payments for reinsurance and insurance premiums paid to unrelated third parties,
but also  included  commissions  paid to Tall Pines,  Valmont and EWI. In Kronos
Worldwide's  opinion,  the amounts that Kronos  Worldwide and LPC paid for these
insurance  policies and the allocation among Kronos Worldwide and its affiliates
of relative insurance premiums are reasonable and at least as favorable to those
they could have  obtained  through  unrelated  insurance  companies  or brokers.
Kronos Worldwide expects that these  relationships with Tall Pines,  Valmont and
EWI will continue in 2004.

     Tax Sharing Agreements. Prior to December 8, 2003, Kronos Worldwide and its
qualifying  subsidiaries  were members of NL's  consolidated U.S. federal income
tax  group  (the  "NL Tax  Group").  As a  member  of the NL Tax  Group,  Kronos
Worldwide was a party to a tax sharing  agreement (the "NL Tax Agreement").  The
NL Tax Group, including Kronos Worldwide,  was included in the consolidated U.S.
federal tax return of Contran  (the  "Contran  Tax  Group").  As a member of the
Contran  Tax  Group,  NL is a party to a separate  tax  sharing  agreement  (the
"Contran Tax  Agreement").  The Contran Tax  Agreement  provides that NL and its
qualifying subsidiaries, including Kronos Worldwide, compute provisions for U.S.
income  taxes  on a  separate-company  basis  using  the tax  elections  made by
Contran.  Pursuant to the NL Tax Sharing  Agreement  and using the tax elections
made by Contran,  Kronos Worldwide made payments to or received payments from NL
in amounts  it would have paid to or  received  from the U.S.  Internal  Revenue
Service had it not been a member of NL's  consolidated tax group but instead was
a separate taxpayer. Refunds are limited to amounts previously paid under the NL
Tax Sharing Agreement.

     Effective on the  Distribution  Date,  Kronos  Worldwide and its qualifying
subsidiaries  ceased being members of the NL Tax Group, but Kronos Worldwide and
its qualifying subsidiaries remained as members of the Contran Tax Group. Kronos
Worldwide entered into a new tax sharing agreement with Valhi and Contran, which
contains similar terms to the NL Tax Agreement.

     Pursuant to the NL Tax Agreement, Kronos Worldwide paid NL $10.7 million in
2003.

     Other.  During  2003,  Dr.  Wigdor's  sister-in-law  was employed by Kronos
Worldwide  and was  paid  $42,302  and  received  customary  employee  benefits,
including medical insurance. She continues to be employed by Kronos Worldwide.

                             AUDIT COMMITTEE REPORT

     The  audit  committee  of the  Board of  Directors  is  comprised  of three
directors  and  operates  under  a  written  charter  adopted  by the  Board  of
Directors.  All members of the audit committee meet the  independence  standards
established  by the Board of Directors and the NYSE and  promulgated  by the SEC
under the Sarbanes-Oxley Act of 2002. The audit committee charter is included as
Appendix A to this proxy statement, and shall be available on Kronos Worldwide's
website at www.kronostio2.com in accordance with the NYSE listing standards.

     Kronos   Worldwide's   management  is  responsible  for  preparing   Kronos
Worldwide's  consolidated  financial  statements in accordance  with  accounting
principles  generally accepted in the United States of America ("GAAP").  Kronos
Worldwide's  independent  auditor is responsible for auditing Kronos Worldwide's
consolidated   financial   statements  in  accordance  with  auditing  standards
generally accepted in the United States of America and for expressing an opinion
on the  conformity of Kronos  Worldwide's  financial  statements  with GAAP. The
audit committee assists the Board of Directors in fulfilling its  responsibility
to oversee management's implementation of Kronos Worldwide's financial reporting
process.  In its oversight role, the audit committee  reviewed and discussed the
audited financial statements with management and with PricewaterhouseCoopers LLP
("PwC"), Kronos Worldwide's independent auditor for 2003.

     The audit  committee met privately with PwC and discussed any issues deemed
significant by the  independent  auditor,  including the required  matters to be
discussed by Statement of Auditing  Standards No. 61,  Communication  with Audit
Committee,  as  amended.  PwC  has  provided  to  the  audit  committee  written
disclosures  and the letter  required  by  Independence  Standards  Board No. 1,
Independence  Discussions  with  Audit  Committees,   and  the  audit  committee
discussed with PwC that firm's independence.  The audit committee also concluded
that  PwC's  provision  of  non-audit  services  to  Kronos  Worldwide  and  its
affiliates is compatible with PwC's independence.

     Based upon the foregoing considerations, the audit committee recommended to
the Board of Directors that Kronos Worldwide's  audited financial  statements be
included in its Annual Report on Form 10-K for 2003.

     Members  of the  audit  committee  of the Board of  Directors  respectfully
submit the foregoing report.

          Dr. R. Gerald Turner                 George E. Poston
          Chairman of the Audit Committee      Member of the Audit Committee

                           INDEPENDENT AUDITOR MATTERS

     Independent Auditor.  PwC served as Kronos Worldwide's  independent auditor
for the year ended December 31, 2003.  NL's audit committee has appointed PwC to
review Kronos Worldwide's quarterly unaudited  consolidated financial statements
to be  included  in its  Quarterly  Reports  on Form  10-Q for the  first  three
quarters  of  2004.   Kronos  Worldwide  expects  PwC  will  be  considered  for
appointment to audit Kronos Worldwide's annual consolidated financial statements
for the year ending December 31, 2004.  Representatives  of PwC are not expected
to attend the Meeting.

     Fees Paid to PwC.  The  following  table shows the  aggregate  fees PwC has
billed or is  expected  to bill to Kronos  Worldwide  and its  subsidiaries  for
services rendered for 2002 and 2003.

                                             ============   ============

- --------------------

(1)  Fees for the following services:

     (a)  audits of consolidated year-end financial statements for each year;
     (b)  reviews of the unaudited quarterly financial  statements  appearing in
          Forms 10-Q for each of the first three quarters of each year;
     (c)  consents and assistance with  registration  statements  filed with the
          SEC;
     (d)  normally provided  statutory or regulatory  filings or engagements for
          each year; and
     (e)  the  estimated  out-of-pocket  costs PwC incurred in providing  all of
          such services for which PwC is reimbursed.

(2)  Fees for assurance and related services  reasonably related to the audit or
     review of Kronos  Worldwide's  financial  statements  for each year.  These
     services  included employee benefit plan audits,  accounting  consultations
     and attest services concerning financial accounting and reporting standards
     and advice concerning internal controls.

(3)  Fees for tax compliance, tax advice and tax planning services.

(4)  Fees for all services  not  described  in the other  categories.  For 2002,
     these services consisted of certain payroll administration services.

     Preapproval  Policies and  Procedures.  The audit  committee  has adopted a
preapproval  policy,  a copy of which is  attached  as  Appendix B to this proxy
statement.  As of May 6,  2003,  NL's audit  committee  became  responsible  for
preapproving  every  engagement of PwC to perform audit or nonaudit  services on
behalf of Kronos Worldwide or any of its  subsidiaries.  As of December 8, 2003,
Kronos  Worldwide's  audit committee became  responsible for preapproving  these
engagements.  Since  May 6,  2003,  either  NL's  or  Kronos  Worldwide's  audit
committee preapproved all of PwC's services. Accordingly, there were no services
for  which  the  de  minimus  exception,  as  defined  in  Section  202  of  the
Sarbanes-Oxley Act of 2002, was applicable.

                                      -24-


                                  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  reasonable
judgment.

   STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS FOR THE 2005 ANNUAL MEETING

     Stockholders  may submit  proposals on matters  appropriate for stockholder
action at Kronos Worldwide's annual stockholders meetings, consistent with rules
adopted by the SEC. Kronos  Worldwide must receive such proposals not later than
December 18, 2004 to be considered for inclusion in the proxy statement and form
of proxy card relating to the Annual  Meeting of  Stockholders  in 2005.  Kronos
Worldwide's  bylaws require that the proposal must set forth a brief description
of the  proposal,  the name and  address of the  proposing  stockholder  as they
appear on Kronos  Worldwide's  books,  the number of shares of Common  Stock the
stockholder holds and any material interest the stockholder has in the proposal.

     The Board of Directors will consider the director  nominee  recommendations
of Kronos  Worldwide  stockholders.  Kronos  Worldwide's  bylaws  require that a
nomination  set forth the name and  address  of the  nominating  stockholder,  a
representation  that the stockholder will be a stockholder of record entitled to
vote at the annual  stockholders  meeting  and intends to appear in person or by
proxy at the meeting to nominate the nominee,  a description of all arrangements
or  understandings  between the  stockholder  and the nominee (or other  persons
pursuant  to  which  the  nomination  is to be  made),  such  other  information
regarding  the nominee as would be required to be included in a proxy  statement
filed  pursuant  to the proxy rules of the SEC and the consent of the nominee to
serve as a Kronos Worldwide director if elected.

     The Board of Directors has no specific minimum  qualifications for director
candidates.  The Board of Directors will consider a potential director nominee's
ability to satisfy the need, if any, for any required  expertise on the Board of
Directors or one of its committees.  Historically, Kronos Worldwide's management
has recommended  director nominees to the Board of Directors.  Because under the
NYSE  listing  standards  Kronos  Worldwide  may be  deemed  to be a  controlled
company,  the Board of Directors  believes  that it is  appropriate  that Kronos
Worldwide  not have any  additional  policies or  procedures  with regard to the
consideration of director candidates recommended by its stockholders.

     For  proposals  or  director  nominations  to be brought at the 2005 Annual
Meeting  of  Stockholders  but not  included  in the  proxy  statement  for such
meeting,  Kronos Worldwide's bylaws require that the proposal or nomination must
be delivered or mailed to the principal executive offices of Kronos Worldwide no
later  than  forty-five  days  prior  to the  earlier  of the date (as if in the
current year) on which notice of the date of the last annual  meeting was mailed
or  public  disclosure  of the  date of the  meeting  was  made.  Proposals  and
nominations should be addressed to: Corporate Secretary, Kronos Worldwide, Inc.,
Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697.

                   COMMUNICATIONS WITH THE BOARD OF DIRECTORS

     Stockholders  who wish to communicate with the Board of Directors may do so
through the  following  procedures.  Stockholder  communications  not  involving
complaints or concerns regarding  accounting,  internal  accounting controls and
auditing  matters  related  to  Kronos  Worldwide  ("Accounting   Complaints  or
Concerns")  may be sent to  Kronos  Worldwide's  corporate  secretary  at Kronos
Worldwide,  Inc., Three Lincoln Centre,  5430 LBJ Freeway,  Suite 1700,  Dallas,
Texas  75240-2697.  Stockholder  communications  that relate to matters that are
within  the  scope of the  responsibilities  of the Board of  Directors  and its
committees,  or  summaries  of such  communications,  will be  forwarded  to the
chairman of the audit committee.

     Accounting Complaints or Concerns, which may be made anonymously, should be
sent to Kronos  Worldwide's  general  counsel with a copy to Kronos  Worldwide's
chief  financial  officer  at  the  same  address  as the  corporate  secretary.
Accounting Complaints or Concerns will be forwarded to the chairman of the audit
committee.   Kronos  Worldwide  will  keep  Accounting  Complaints  or  Concerns
confidential and anonymous,  to the extent feasible,  subject to applicable law.
Information  contained in an Accounting  Complaint or Concern may be summarized,
abstracted and aggregated for purposes of analysis and investigation.

                         2003 ANNUAL REPORT ON FORM 10-K

     A copy of Kronos Worldwide's Annual Report on Form 10-K for the fiscal year
ended  December  31,  2003,  as filed with the SEC,  is  included as part of the
annual  report  mailed  to  Kronos  Worldwide's  stockholders  with  this  proxy
statement.  This  Annual  Report  on Form  10-K may also be  accessed  on Kronos
Worldwide's website at www.kronostio2.com.

                                ADDITIONAL COPIES

     Pursuant to an SEC rule concerning the delivery of annual reports and proxy
statements,  a single set of these  documents  may be sent to any  household  at
which two or more  stockholders  reside if they appear to be members of the same
family.  Each  stockholder  continues  to receive a separate  proxy  card.  This
procedure,  referred  to  as  householding,  reduces  the  volume  of  duplicate
information  stockholders  receive and reduces mailing and printing expenses.  A
number of  brokerage  firms have  instituted  householding.  Certain  beneficial
stockholders who share a single address may have received a notice that only one
annual  report  and  proxy  statement  would  be sent to that  address  unless a
stockholder  at that  address  gave  contrary  instructions.  If, at any time, a
stockholder who holds shares through a broker no longer wishes to participate in
householding  and would prefer to receive a separate proxy statement and related
materials,  or if such  stockholder  currently  receives  multiple copies of the
proxy  statement  and related  materials at his or her address and would like to
request householding of Kronos Worldwide communications,  the stockholder should
notify his or her broker. Additionally, Kronos Worldwide will promptly deliver a
separate copy of Kronos  Worldwide's  2003 annual report or this proxy statement
to any  stockholder at a shared address to which a single copy of such documents
was delivered, upon the written or oral request of the stockholder.

     To obtain  copies of Kronos  Worldwide's  2003 annual  report or this proxy
statement  without  charge,  please  mail your  request  to  Robert  D.  Graham,
Corporate Secretary,  at Kronos Worldwide,  Inc., Three Lincoln Centre, 5430 LBJ
Freeway, Suite 1700, Dallas, Texas 75240-2697, or call him at 972.233.1700.

                                    PURPOSE

     The   audit   committee   assists   the  board  of   directors'   oversight
responsibilities  relating to the financial  accounting and reporting  processes
and auditing  processes of the corporation.  The audit committee shall assist in
the oversight of:

     -    the integrity of the corporation's financial statements;

     -    the corporation's compliance with legal and regulatory requirements;

     -    the independent auditor's qualifications and independence; and

     -    the  performance  of the  corporation's  internal  audit  function and
          independent auditor.

                                   ARTICLE II.
            RELATIONSHIP WITH MANAGEMENT AND THE INDEPENDENT AUDITOR

     Management  is  responsible  for  preparing  the  corporation's   financial
statements.  The corporation's  independent  auditor is responsible for auditing
the financial  statements.  The activities of the audit  committee are in no way
designed  to  supersede  or  alter  these  traditional   responsibilities.   The
corporation's  independent auditor and management have more time,  knowledge and
detailed  information about the corporation than do the audit committee members.
Accordingly,  the audit committee's role does not provide any special assurances
with regard to the corporation's financial statements.  Each member of the audit
committee,  in the performance of such member's duties, will be entitled to rely
in good faith upon the information, opinions, reports or statements presented to
the audit committee by any of the corporation's  officers or employees or by any
other person as to matters such member reasonably believes are within such other
person's  professional  or  expert  competence  and who has been  selected  with
reasonable care by or on behalf of the corporation.

                                  ARTICLE III.
                             AUTHORITY AND RESOURCES

     The audit  committee  shall have the authority  and resources  necessary or
appropriate  to discharge its  responsibilities.  The audit  committee  shall be
provided with full access to all books, records, facilities and personnel of the
corporation in carrying out its duties.  The audit committee shall have the sole
authority with regard to the independent  auditor as set forth in Article V, and
the authority to engage independent counsel and other advisors, as it determines
is necessary to carry out its duties. The corporation shall provide  appropriate
funding,  as the audit  committee  determines  is  necessary or  appropriate  in
carrying  out its  duties,  for the  committee  to  engage  and  compensate  the
independent auditor or legal counsel or other advisors to the committee,  and to
pay the committee's ordinary administrative expenses.

                                   ARTICLE IV.
                            COMPOSITION AND MEETINGS

     The board of  directors  shall set the number of directors  comprising  the
audit  committee  from time to time,  which number shall not be less than three.
The board of directors shall designate a chairperson of the audit committee. The
number of directors comprising the audit committee and the qualifications, which
members  will  all be  financially  literate  with at least  one  being an audit
committee  financial  expert,  and  independence  of each  member  of the  audit
committee shall at all times satisfy all applicable requirements, regulations or
laws,  including,  without  limitation,  the rules of any  exchange  or national
securities association on which the corporation's securities trade. Simultaneous
service  on more than  three  non-affiliated  public  company  audit  committees
requires a special  determination  by the board of  directors  and, if required,
disclosure  in  the  annual  proxy  statement.  The  board  of  directors  shall
determine, in its business judgment,  whether the members of the audit committee
satisfy all such requirements, regulations or laws.

     The audit  committee  shall meet at least  quarterly  and as  circumstances
dictate.  Regular  meetings of the audit  committee  may be held with or without
prior  notice  at such  time and at such  place as  shall  from  time to time be
determined by the chairperson of the audit committee,  any of the  corporation's
executive officers or the secretary of the corporation.  Special meetings of the
audit  committee  may be called by or at the  request of any member of the audit
committee,  any of the corporation's  executive  officers,  the secretary of the
corporation or the  independent  auditor,  in each case on at least  twenty-four
hours notice to each member.

     A majority of the audit committee members shall constitute a quorum for the
transaction of the audit  committee's  business.  The audit  committee shall act
upon the vote of a majority of its  members at a duly called  meeting at which a
quorum is present.  Any action of the audit  committee may be taken by a written
instrument signed by all of the members of the audit committee.  Meetings of the
audit committee may be held at such place or places as the audit committee shall
determine or as may be specified or fixed in the respective  notice or waiver of
notice for a meeting.  Members of the audit  committee may  participate in audit
committee proceedings by means of conference telephone or similar communications
equipment by means of which all persons  participating  in the  proceedings  can
hear each other, and such participation  shall constitute  presence in person at
such proceedings.

                                   ARTICLE V.
                                RESPONSIBILITIES

following activities.

          and financial  information and earnings  guidance provided to analysts
          and rating  agencies.  The audit committee need not discuss in advance

          the  purpose of  preparing  or issuing an audit  report or  performing

                      Section 1. -- Statement of Principles

     The Audit  Committee  is  required,  subject to any  de-minimus  exceptions
permitted by applicable law or regulation, to preapprove the audit and non-audit
services  performed  by the  independent  auditor  in order to  assure  that the

     This Policy applies to services provided by the accounting firm that serves
Kronos  Worldwide,  Inc. and its  subsidiaries  (the  "Company")  as its primary
independent auditor, and any international affiliates thereof.

     Unless a type of  service  to be  provided  by the  independent  auditor is
subject to  preapproval  under  Sections 3 or 4 of this Policy,  it will require
specific  preapproval by the Audit Committee under Section 2 of this Policy.  In
addition,  any proposed  services subject to preapproval under Section 3 of this
Policy  that  exceeds the  applicable  preapproved  fee level will also  require
preapproval under either Section 2 or Section 4 of this Policy.  Notwithstanding
the foregoing,  the  preapproval  requirements  under this Policy is waived with
respect to the provision of permitted  non-Audit  Services to the extent allowed
by applicable law or regulation.

                       Section 2. -- Specific Preapproval

     Subject to Sections 4 and 5 of this Policy,  the  following  describes  the
Audit and Audit-related  services to be provided by the independent auditor that

auditor can be engaged:

          attestation  services associated with the Company's system of internal
          control over financial  reporting and other services  associated  with
          the Company's Annual Report on Form 10-K;
     -    Quarterly review  procedures  associated with the Company's  unaudited
          interim   consolidated   financial   statements   and  other  services
          associated with the Company's Quarterly Reports on Form 10-Q;
     -    Services associated with registration  statements filed by the Company
          with  the  Securities  and  Exchange  Commission  ("SEC"),   including
          responding to SEC comment letters and providing comfort letters;
     -    Statutory audits or annual audits of the annual  financial  statements
          of subsidiaries of the Company;
     -    Quarterly  review  procedures of the interim  financial  statements of
          subsidiaries of the Company;
     -    Services associated with potential business  acquisitions/dispositions

     -    Any material changes in terms,  conditions or fees with respect to the

          other applicable matters.

                  Section 3. -- Other Categories of Preapproval

reasonably  related to the  performance  of the audit or review of the Company's
financial  statements and that are  traditionally  performed by the  independent
auditor.  The Audit Committee believes that the provision of all of the services
described  below  does  not  impair  the  independence  of  the  auditor  and is
consistent with the SEC's rules on auditor independence.
