                                 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 NL
Industries,  Inc., a New Jersey  corporation (the "Company" or "NL"), for use at
the  Company's  2002  Annual  Meeting of  Shareholders  to be held at 10:00 a.m.
(C.D.T.) on  Wednesday,  May 8, 2002, at the offices of Valhi,  Inc.  located at
Three Lincoln Centre,  5430 LBJ Freeway,  Suite 1700, Dallas,  Texas 75240-2697,
and at any  adjournment or  postponement  thereof (the "Annual  Meeting").  This
Proxy Statement and the accompanying  proxy card or voting instruction form were
first mailed to the holders of the Company's  common stock,  $.125 par value per
share ("Common Stock"), on or about April 8, 2002.


                            PURPOSE OF ANNUAL MEETING

        At the Annual  Meeting,  shareholders  of the Company will  consider and
vote upon (i) the election of seven  directors to serve until the Company's 2003
Annual Meeting of Shareholders  and until their  successors are duly elected and
qualified,  and (ii) such other  business as may properly come before the Annual
Meeting.  The Company is not aware of any other business expected to come before
the Annual Meeting.


                  QUORUM AND VOTING RIGHTS; PROXY SOLICITATION

        The  presence  in person or by proxy of the holders of a majority of the
votes represented by the outstanding  shares of Common Stock entitled to vote at
the Annual  Meeting  is  necessary  to  constitute  a quorum for the  conduct of
business at the Annual Meeting. Director nominees will be elected by a plurality
of the votes  cast.  Except as may be  provided  in the  Company's  Amended  and
Restated Certificate of Incorporation (the "Certificate"), any other matter that
may be submitted to a shareholder  vote will require the  affirmative  vote of a
majority of the votes cast at the Annual  Meeting.  Shares of Common  Stock that
are voted to  abstain  from  business  coming  before  the  Annual  Meeting  and
broker/nominee  non-votes  will be counted as being in  attendance at the Annual
Meeting for purposes of determining whether a quorum is present, but will not be
counted as votes for or against any matter coming before the Annual Meeting. The
accompanying  proxy card provides space for a shareholder to withhold voting for
any or all  nominees for the Board.  Because  director  nominees  must receive a
plurality  of the votes  cast at the  Annual  Meeting,  a vote  withheld  from a
particular nominee will not affect the election of that nominee.

        The record date for determination of shareholders entitled to notice of,
and to vote at, the Annual  Meeting is the close of  business  on March 18, 2002
(the "Record  Date").  As of the Record Date,  there were issued and outstanding
48,820,984 shares of Common Stock, each of which entitles the holder to one vote
on all matters that come before the Annual Meeting.  Valhi,  Inc.  ("Valhi") and
Tremont Corporation ("Tremont") held approximately 62% and 21%, respectively, of
the  outstanding  shares  of the  Common  Stock as of the  Record  Date and have
indicated  their  intention  to have  their  shares  represented  at the  Annual
Meeting. Valhi is a diversified company engaged in the titanium dioxide pigments
(through its ownership of NL stock), component products (ergonomic computer



support systems, precision ball bearing slides and security products),  titanium
metals products, and waste management  industries.  Tremont is a holding company
engaged in the titanium metals and titanium dioxide pigments industries (through
its  ownership of NL stock).  Both Valhi and Tremont are  affiliates  of Contran
Corporation  ("Contran").  See "Security Ownership" and "Election of Directors."
If the shares of Common  Stock held by Valhi and Tremont  together or the shares
of Common Stock held by Valhi alone are  represented  at the Annual  Meeting,  a
quorum will be present.

        All shares of Common  Stock  represented  by properly  executed  proxies
will, unless such proxies have been previously  revoked,  be voted in accordance
with the  instructions  indicated in such proxies.  If no such  instructions are
indicated, such shares will be voted (i) "FOR" the election of each of the seven
nominees  for  director,  and (ii) to the extent  allowed by federal  securities
laws,  in the  discretion  of the proxy  holders  on any other  matter  that may
properly  come  before the Annual  Meeting.  Any holder of Common  Stock has the
unconditional  right to revoke  his or her proxy at any time prior to the voting
thereof at the Annual Meeting by (i) filing with the Company's Secretary written
revocation  of his or her proxy,  (ii) giving a duly  executed  proxy  bearing a
later date,  or (iii) voting in person at the Annual  Meeting.  Attendance  by a
shareholder  at the Annual  Meeting will not in and of itself  revoke his or her
proxy.

        This  proxy  solicitation  is  made  by and  on  behalf  of  the  Board.
Solicitation  of  proxies  for use at the  Annual  Meeting  may be made by mail,
telephone or in person,  by  directors,  officers and  employees of the Company.
Such  persons  will  receive no  additional  compensation  for any  solicitation
activities.  The Company will request  banking  institutions,  brokerage  firms,
custodians, trustees, nominees and fiduciaries to forward solicitation materials
to the beneficial  owners of Common Stock held of record by such  entities,  and
the Company will, upon the request of such record holders,  reimburse reasonable
forwarding expenses.  The costs of preparing,  printing,  assembling and mailing
the Proxy  Statement,  proxy card or voting  instruction  form and all materials
used in the  solicitation of proxies from  shareholders of the Company,  and all
clerical and other expenses of such solicitation, will be borne by the Company.

        EquiServe  Trust  Company,  N.A.  ("EquiServe"),  the transfer agent and
registrar  for the Common  Stock,  has been  appointed  by the Board to serve as
inspector of election  (the  "Inspector of Election") to determine the number of
shares of Common Stock represented and voted at the Annual Meeting.  All proxies
and ballots  delivered to EquiServe  shall be kept  confidential by EquiServe in
accordance with the terms of the Company's By-Laws.

        THE AGENTS  DESIGNATED  IN THE  ENCLOSED  PROXY CARD WILL VOTE "FOR" THE
ELECTION OF ALL SEVEN NOMINEES FOR DIRECTOR IDENTIFIED BELOW UNLESS AUTHORITY IS
WITHHELD  BY  THE  SHAREHOLDER  GRANTING  THE  PROXY.  IF  ANY  NOMINEE  BECOMES
UNAVAILABLE  TO SERVE FOR ANY REASON,  THE PROXY WILL BE VOTED FOR A  SUBSTITUTE
NOMINEE  OR  NOMINEES  TO BE  SELECTED  BY THE  BOARD,  UNLESS  THE  SHAREHOLDER
WITHHOLDS  AUTHORITY TO VOTE FOR THE ELECTION OF  DIRECTORS.  VALHI AND TREMONT,
WHICH HOLD  APPROXIMATELY 62% AND 21%,  RESPECTIVELY,  OF THE OUTSTANDING COMMON
STOCK,  HAVE  INFORMED  THE COMPANY THAT THEY WILL VOTE THEIR SHARES IN FAVOR OF
THE  NOMINEES SET FORTH IN THIS PROXY  STATEMENT.  VALHI'S AND  TREMONT'S  VOTES
TOGETHER, OR VALHI'S VOTES ALONE, ARE SUFFICIENT TO ELECT ALL SEVEN NOMINEES.


                              ELECTION OF DIRECTORS

        The Certificate  provides for a Board  consisting of not less than seven
and not more than seventeen  persons,  as such number is determined from time to
time by a majority of the entire Board.  The Board has determined  that it shall
consist of seven members.

        At the Annual  Meeting,  holders of Common  Stock will be asked to elect
seven  nominees  to the Board,  each to serve for a one-year  term ending at the
2003 Annual Meeting of Shareholders and until his or her successor shall have



been elected and qualified or until his or her earlier  resignation,  removal or
death. All of the nominees have agreed to serve if elected.

        THE BOARD OF DIRECTORS  RECOMMENDS A VOTE "FOR" THE NOMINEES  IDENTIFIED
BELOW.

        The Board  held five  meetings  and took  action  by  unanimous  written

Company.

        Audit Committee.  The principal  responsibilities of the Audit Committee
are to serve as an  independent  and  objective  party to review  the  Company's
auditing,  accounting, and financial reporting processes. The Company's Board of
Directors  has adopted a written  charter for the Audit  Committee.  Each of the
members of the Audit Committee is independent within the meaning of the New York
Stock  Exchange  listing  standards.  The Audit  Committee held five meetings in

matters of key  personnel  selection,  organization  strategies,  and such other
matters as the Board may from time to time direct.  The  Management  Development
and Compensation Committee also is responsible for reviewing and approving stock
option and other stock-based  compensation  awards under the Company's incentive
plan and for reviewing and approving the Company's target and performance levels
under  the  Variable   Compensation   Plan.  The  Management   Development   and
Compensation  Committee  held one meeting and took action by written  consent in
lieu of a meeting on three  occasions in 2001. Its current  members are Mr. Peak
(Chairman) and General Stafford.

        Nominations Committee. The principal responsibilities of the Nominations
Committee are to review and make  recommendations  to the Board  regarding  such
matters  as the size and  composition  of the Board and  criteria  for  director
nominations,  director  candidates,  the term of office of  directors,  and such
other  related  matters  as the  Board  may  request  from  time  to  time.  The
Nominations  Committee  held one  meeting in 2001.  The  current  members of the
Nominations  Committee are Mr. Glenn Simmons (Chairman),  General Stafford,  and

Directors with respect to the election of directors at the Annual  Meeting.  The

Company with respect to nominees for election as director if such



recommendations  are  submitted  in writing to the  Secretary of the Company and
received not later than December 31 of the year prior to the next annual meeting
of shareholders,  and are accompanied by a full statement of qualifications  and
confirmation of the recommended nominees' willingness to serve.

        The  Board  has  previously  established,  and  from  time to  time  may
establish, other committees to assist it in discharging its responsibilities.

        owned by such individual as to which he disclaims beneficial  ownership.
        See note (3) to the  table  following  "Ownership  of NL  Common  Stock"
        above.

(4)     The shares of Tremont Common Stock shown as beneficially owned by Thomas
        P. Stafford include 4,000 shares which General Stafford has the right to
        acquire by exercise of options within 60 days of the Record Date.

(5)     Includes  shares  that  such  person  or group  could  acquire  upon the
        exercise of stock options within 60 days of the Record Date. During such
        60-day  period,  options for 200,000  shares of Valhi  Common  Stock are
        exercisable by Glenn R. Simmons, and options for 170,000 shares of Valhi
        Common Stock are  exercisable  by Steven L. Watson,  all of which shares
        are included in the amount  outstanding  for purposes of calculating the
        percent of class owned by such persons.  Also includes 3,035 shares held
        in Mr. Watson's individual retirement account.

(6)     Includes  2,383  shares of Valhi  Common  Stock and 19 shares of Tremont
        Common Stock held in Glenn R. Simmons'  individual  retirement  account.
        The Valhi shares also  include 800 shares held in a  retirement  account
        for Mr. Simmons' wife, with respect to all of which beneficial ownership
        is disclaimed by Mr. Simmons.

(7)     Includes  77,000 shares of Valhi Common Stock held by Harold C. Simmons'
        wife,  with respect to which  beneficial  ownership is disclaimed by Mr.
        Simmons.

(8)     The shares of Tremont Common Stock shown as beneficially  owned by Susan
        E. Alderton include 11 shares held by the trustee for the benefit of Ms.
        Alderton under the Savings Plan.

        The Company  understands  that Valhi,  Tremont and related  entities may
consider acquiring or disposing of shares of Common Stock through open-market or
privately   negotiated   transactions,   depending  upon  future   developments,
including,  but not limited to, the  availability and alternative uses of funds,
the performance of the Common Stock in the market, an assessment of the business
of and prospects  for the Company,  financial  and stock market  conditions  and
other factors deemed  relevant by such entities.  The Company does not presently
intend,  and understands that neither Valhi nor Tremont  presently  intends,  to
engage in any  transaction  or series of  transactions  that would result in the
Common  Stock  becoming  eligible  for  termination  of  registration  under the
Securities  Exchange  Act of 1934,  as  amended,  or  ceasing  to be traded on a
national securities exchange.

        The Company further  understands that approximately 30 million shares of
Common Stock held by Valhi (61.4% of the shares of Common Stock outstanding) are
pledged to secure bank  borrowings by Valhi.  Foreclosure  by the lender on this
pledge in the event of Valhi's default on the loan,  which Valhi has advised the
Company is unlikely,  may at a subsequent  date result in a change in control of
the Company.


             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section  16(a)  of the  Securities  Exchange  Act of 1934,  as  amended,
requires  the  Company's  executive  officers,  directors,  and  persons who own
beneficially  more  than  10% of a  registered  class  of the  Company's  equity
securities  to file  reports of  ownership  and  changes in  ownership  with the
Commission,  the New York Stock Exchange,  the Pacific Exchange and the Company.
Based solely on a review of copies of the Section 16(a) reports furnished to the
Company and written  representations by certain reporting  persons,  the Company
believes that all of the  Company's  executive  officers,  directors and greater
than 10% beneficial  owners filed on a timely basis all reports  required during
and with respect to the fiscal year ended December 31, 2001.



                COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS
                              AND OTHER INFORMATION

Compensation of Directors

        During 2001,  fees were paid to each director who was not an employee of
the Company or a subsidiary of the Company. Fees consisted of an annual retainer
of $15,000,  payable in quarterly  installments and 1,000 shares of Common Stock
granted  pursuant to the 1998 Incentive  Plan,  plus an attendance fee of $1,000
for each  meeting of the Board or a committee at which the director was present.
Such  directors  also  received a fee of $1,000 per day for each day spent on NL
business  at the request of the Board or the  Chairman of the Board,  other than
the day of Board or committee meetings.  Directors are reimbursed for reasonable
expenses incurred in attending Board of Directors and committee meetings. If any
director who is not an officer or employee of NL or any  subsidiary or affiliate
of NL dies while in active service, his or her designated  beneficiary or estate
will be  entitled  to  receive  a life  insurance  benefit  equal to the  annual
retainer then in effect. Nominees for election as Director who received fees for
serving on the Board of Directors in 2001 are Ms. Manix,  Messrs. G. Simmons, H.
Simmons,  and Watson,  and General  Stafford.  See  "Certain  Relationships  and
Transactions."  In  addition,  General  Stafford  receives an annual  payment of
$15,000 as a result of his service on the Board in the period prior to 1987.

        In 2001, Messrs.  Peak, G. Simmons, H. Simmons,  and Watson, and General
Stafford  each were  granted an option  pursuant to the 1998  Incentive  Plan to
purchase 2,000 shares of Common Stock at an exercise price of $20.513 per share,
representing the average of the high and low sales prices of Common Stock on the
New York Stock Exchange  Composite Tape on the date of the grant.  These options
become  exercisable  one year  after the date of grant  and  expire on the fifth
anniversary following the date of the grant.

(1)   No payouts under any long-term  incentive  plans (as defined by applicable
      federal  securities  regulations)  were made  during  2001,  2000 or 1999.
      Therefore  the  column  for  such  compensation   otherwise   required  by
      applicable federal securities regulations has been omitted.

(2)   Amounts  paid  with  respect  to  each  year   pursuant  to  the  Variable
      Compensation Plan and, for 2000 and 2001, special  discretionary  bonuses.
      See "Compensation Committee's Report on Executive Compensation" below.

(3)   Includes the amount which exceeds 120% of the applicable federal long-term
      interest rate accrued on deferred compensation.  In the case of Mr. Martin
      in 2001,  the amount  shown  includes  $8,114 of such excess  interest and
      $50,518 in value attributed to use of the Company's aircraft by him.

(4)   During 2001, 2000 and 1999, Mr. Martin also served as an executive officer
      of Tremont  and TIMET.  Mr.  Martin is expected to continue to serve as an
      executive  officer of NL, TIMET and Tremont in 2002 and to be  compensated
      directly by NL for  services to NL and by TIMET for  services to TIMET and
      Tremont.  Mr.  Martin is  expected  to  continue  to devote  approximately
      one-half  of his  working  time  to his  duties  as  President  and  Chief
      Executive Officer of NL. See "Certain Relationships and Transactions."


(5)   "All Other Compensation" amounts represent (i) matching contributions made
      or accrued by the Company  pursuant to the savings  feature of the Savings
      Plan,  (ii)  retirement  contributions  made  or  accrued  by the  Company
      pursuant to the Savings Plan,  (iii) life  insurance  premiums paid by the
      Company,  and (iv) amounts  accrued by the Company under the  Supplemental
      Executive  Retirement  Plan  ("SERP")  for 2000 and 1999,  and paid by the
      Company under the SERP in 2001. See  "Compensation  Committee's  Report on
      Executive  Compensation"  and "Certain  Relationships  and  Transactions -

(1)     Grants of options to purchase shares of Common Stock under the Incentive
        Plan vest over five  years  from the date of grant,  at a rate of 40% on
        the second anniversary of the date of grant, and 20% on each of the next
        three  succeeding  anniversary  dates.  The options  expire on the tenth
        anniversary date of the date of grant.

(2)     Exercise  price is equal to the mean of the high and low  prices  of the
        Common Stock on the New York Stock  Exchange  Composite Tape on the date
        of grant.

(3)     Pursuant  to the rules of the  Commission,  these  amounts  reflect  the
        calculations  at  assumed  5% and 10% annual  appreciation  rates.  Such
        calculations are not intended to forecast future  appreciation,  if any,
        and do not  necessarily  reflect the actual  value,  if any, that may be
        realized.  The actual value of such options,  if any,  would be realized
        only upon the  exercise  of such  options  and  depends  upon the future
        performance  of the  Common  Stock.  No  assurance  can be made that the
        amounts  reflected  in these  columns will be  achieved.  The  potential
        realizable value was computed as the difference  between the appreciated
        value (at the end of the  ten-year  term of the  options)  of the Common
        Stock into which the listed  options are  exercisable  and the aggregate
        exercise price of such options.  The appreciated  value per share at the
        end of the  ten-year  term would be $32.76 and $52.16 at the  assumed 5%
        and 10% rates,  respectively,  with respect to options  granted to named
        executive officers.

(4)     As a director, Harold C. Simmons was granted an option to purchase 2,000
        shares of Common Stock representing 0.4% of the total options granted to
        employees  during  the  fiscal  year at an  exercise  price of  $20.513,
        representing  the  average  of the high and low  sales  prices of Common
        Stock on the New York Stock  Exchange  Composite Tape on the date of the
        grant.  The option became  exercisable one year after the date of grant,
        expires 2/1/06,  and has a potential  realizable  value at an assumed 5%
        and 10% rate of stock appreciation of $11,353 and $25,069, respectively.
        See  "Compensation  of  Directors  and  Executive   Officers  and  Other
        Information - Compensation of Directors."

Stock Option Exercises and Holdings

        The following  table  provides  information  with respect to the persons
named in the Summary  Compensation  Table,  as set forth above,  concerning  the
exercise of options  during the last  fiscal  year and the value of  unexercised
options  held as of December 31, 2001.  None of such persons  exercised  options
during 2001 as shown in the table below. No stock appreciation  rights have been
granted under the Incentive Plans.

employees.  In 1996, the Company  approved the suspension of all future accruals
under the salaried  component of the Pension Plan.  The Pension Plan covers each
person named in the Summary  Compensation Table set forth above. No amounts were
paid or distributed to any of such persons in 2001. The estimated accrued annual
benefits payable under the Pension Plan upon retirement at normal retirement age
for Dr. Wigdor, Ms. Alderton, and Messrs. Martin, Garten, and Hardy are $29,439,
$34,419, $50,277, $26,410, and $12,348, respectively.

Severance Agreements

        Mr. Martin had an executive  severance  agreement with the Company which
expired in December 2001. The agreement  provided that he could be terminated at
any time by action of the Board of Directors.  The executive severance agreement

                           INDEPENDENT AUDITOR MATTERS

        Independent Auditors. The firm of  PricewaterhouseCoopers  LLP served as
NL's  independent  auditor for the year ended  December 31,  2001,  and has been
appointed to review NL's quarterly unaudited  consolidated  financial statements
to be  included  in its  Quarterly  Reports  on Form  10-Q for the  first  three
quarters of 2002 and to audit NL's annual consolidated  financial statements for
the year ending December 31, 2002. Representatives of PricewaterhouseCoopers LLP
are not expected to attend the Meeting.

        Audit  Committee  Report.  NL's  management is responsible for preparing
NL's consolidated  financial statements in accordance with accounting principles
generally   accepted  in  the  United   States.   NL's   independent   auditors,
Pricewaterhouse  Coopers LLP, are  responsible  for auditing  NL's  consolidated
financial statements in accordance with auditing standards generally accepted in
the United States of America.  Our  responsibility as NL's Audit Committee is to
monitor  and  review  these   auditing,   accounting  and  financial   reporting
processes.  However,  we are not  professionally  engaged  in the  practice  of
accounting  or  auditing  and are not  experts  in the fields of  accounting  or
auditing.  We have relied,  without  independent  verification,  on management's
representation  that the financial  statements have been prepared with integrity
and objectivity and in conformity with accounting  principles generally accepted
in   the   United   States   of   America   and  on   the   representations   of
PricewaterhouseCoopers  LLP included in their report on the Company's  financial
statements.

         We have  reviewed and  discussed  NL's audited  consolidated  financial
statements  for the year  ended  December  31,  2001  with NL's  management  and
PricewaterhouseCoopers  LLP. We discussed  with  PricewaterhouseCoopers  LLP the
matters required by Statement on Auditing Standards No. 61 ("Communication  with
Audit Committees"), received from PricewaterhouseCoopers LLP written disclosures
required  by  Independence   Standards  Board  Standard  No.  1   ("Independence
Discussions with Audit  Committees")  and discussed with  PricewaterhouseCoopers
LLP   its    independence.    We   also   considered    whether   provision   by
PricewaterhouseCoopers  LLP of non-audit  services to NL and its subsidiaries is
compatible  with such auditor's  independence.  Additionally,  we discussed with
NL's management and  PricewaterhouseCoopers  LLP such other matters as we deemed
appropriate.  Based  on  our  review  of  NL's  audited  consolidated  financial
statements and our discussions  with NL's management and  PricewaterhouseCoopers
LLP, we  recommended  to the Board of Directors  that NL's audited  consolidated
financial  statements  for the year ended  December 31, 2001 be included in NL's
Annual Report on Form 10-K for the year ended December 31, 2001,  which has been
filed with the Commission.

consulting services.


                  COMPENSATION COMMITTEE'S REPORT ON EXECUTIVE COMPENSATION

        The Company's  Management  Development and  Compensation  Committee (the
"MDC Committee")  consists of individuals who are neither officers nor employees
of the Company or its  subsidiaries  and who are not eligible to  participate in
any of the employee benefit plans administered by the MDC Committee.

        The MDC Committee annually reviews and recommends  compensation policies
and practices related to the Company's executive  officers,  including the Chief
Executive  Officer (the  "CEO").  The MDC  Committee  also was  responsible  for
reviewing  and  approving  all  compensation   actions  during  2001,  including
stock-based compensation,  involving the Company's executive officers.  However,
any action in connection  with the CEO's base salary is reviewed and approved by
the Board after recommendation by the MDC Committee.

        The  Company's  executive   compensation  system  with  respect  to  its
executive  officers,  including  the CEO,  generally  consists of three  primary
components:  base salary,  annual variable compensation provided by the Variable
Compensation Plan, and the grant of stock options, restricted stock and/or stock
appreciation  rights.  Through the use of the foregoing,  the 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 officers to maximize annual operating  performance and
long-term shareholder value.

Base Salaries

        The MDC Committee reviews  recommendations  by the CEO regarding changes
in  base   salaries  for   executive   officers,   including   the  CEO.   These
recommendations  are made by the CEO after consultation with the Chairman of the
Board. When recommendations  regarding changes in base salary levels are made by
the CEO, the MDC Committee may take such actions,  including any  modifications,
as it deems  appropriate.  The  CEO's  recommendations  and the MDC  Committee's
actions in 2001 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.  The
Committee also had available to it  compensation  data from companies  employing
executives in positions  similar to those whose  salaries were being reviewed as
well as,  with  respect  to certain  executives,  compensation  information  for
executives in general with similar skills,  background and  performance  levels,
both inside and  outside of the  chemicals  industry  (such  companies  may have
included 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 the Company, or where the executive in question has
similar  responsibilities.  In 2001,  the MDC  Committee  approved a base annual
salary increase for Ms. Alderton from $325,000 to $350,000, a base annual salary
increase for Mr. Garten from $325,000 to $425,000, and a base annual salary




increase for Mr. Hardy from $275,000 to $300,000. Ms. Alderton subsequently left
the Company's employment in February 2002. In approving these increases, the MDC
Committee reviewed the recommendations of the CEO and an independently  prepared
compensation  survey report.  The MDC Committee also  considered the Chairman of
the  Board's  approval  of these  increases  and the fact that the  Company  had
performed  well in fiscal 2000 as compared to its operating  targets.  The CEO's
base  salary,  which was not changed in 2001,  was not set based on any specific
relationship to Company performance.

        No action was taken  with  respect  to the base  salaries  of any of the
other named executive officers of the Company during 2001.

Variable Compensation Plan

        Awards under the Variable  Compensation  Plan  constitute a  significant
portion of an executive's  potential  annual cash  compensation  (between 0% and
150% of base  salary for the CEO and  executive  officers).  Awards are based on
Kronos  achieving  annual  predetermined  operating  income goals. The Company's
management  makes  recommendations  to the Board regarding the operating  income
plan  for  the  year  after  reviewing  market   conditions  and  the  Company's
operations,  competitive position,  marketing opportunities,  and strategies for
maximizing  financial  performance.  The Board approves this recommendation with
modifications it deems appropriate. Based on the business plan for the year, the
MDC Committee  sets the Company's and its business  segment's  operating  income
goals at three levels which are designed to help focus the Company'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 base 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 a variable  compensation payment
of 50% of base salary. If the Target Level is reached, the variable compensation
payment is 100% of base  salary.  If the Maximum  Level is reached or  exceeded,
executives  are eligible to receive a variable  compensation  payment of 150% of
base salary.  In view of the  achievement  of operating  income above the Target
Level during 2001,  the MDC  Committee in 2002  approved  Target Level  payments
under the Variable  Compensation Plan to the executive  officers,  including the
CEO. Such awards to the CEO and the four other highest paid  executive  officers
under the  Variable  Compensation  Plan are  reported in the bonus column in the
Summary  Compensation  Table set forth  above.  In addition,  Target  levels for
operating  income  performance were utilized by the MDC Committee and the Board,
as applicable,  for determining the contributions by the Company to the accounts
of eligible  participants,  including the CEO and the executive officers,  under
the Savings Plan, the Pension Plan, and the SERP.

Stock-Based Compensation

        The  1998  Incentive  Plan  further  supports  the  goal  of  maximizing
long-term shareholder value by providing for stock-based compensation, the value
of which is directly  related to increases in  shareholder  value.  Stock option
grants,  in particular,  are  considered a significant  element of the Company's
total  compensation  package for the CEO and the other executive officers of the
Company.  The  Committee  believes  that  compensation  linked  to  stock  price
performance  helps focus the executives'  attention on management of the Company
from the shareholders' perspective.

        Option grants are intended to provide incentives to increase shareholder
value in the future and to reward past  performance by the  executive.  In 2001,
the MDC Committee reviewed recommendations by the CEO regarding option grants to
executive officers other than the CEO. Options were granted to executive




officers,  including  the  CEO,  in the MDC  Committee's  discretion  based on a
subjective    evaluation    regarding   each    executive's    performance   and
responsibilities.  In 2001,  the MDC  Committee  included  in its  determination
regarding  the  number of  options  to be  granted  to each  executive  officer,
including  the CEO,  the  amount  and  terms  of  options  already  held by such
officers.  Grants made in 2001 are reported in the Option  Grants in Last Fiscal
Year Table set forth above.

        To help assure a focus on long-term  creation of shareholder  value, the
MDC Committee granted ten year options, which vest 40%, 60%, 80% and 100% on the
second,  third,  fourth  and  fifth  anniversary  dates  of the  date of  grant,
respectively.  Although permitted under the Incentive Plan, the MDC Committee in
2001  did  not  make  or  recommend  any  grants  of  restricted  stock,   stock
appreciation rights or other equity-based awards.

Special Discretionary Bonuses

        Apart from the Variable  Compensation  Plan, the MDC Committee may award
other bonuses as the  Committee  deems  appropriate  from time to time under its
general  authority or under a separate  discretionary  plan.  During  2001,  the
Committee made awards to Ms. Alderton of $200,000,  Mr. Garten of $100,000,  and
Mr. Hardy of $250,000 in  recognition of their  performance  during the year. In
addition during 2001, the Committee awarded Dr. Wigdor $1,500,000 in recognition
of his performance during 2000 and $600,000 in recognition of his performance in
2001.  Such awards are reported in the bonus column in the Summary  Compensation
Table set forth above.

SERP Distribution

        In 2001, the Committee  determined that the Company would  distribute to
participants in the SERP the accrued balance in each participant's  account, and
that future  benefits under the SERP would be paid to  participants  as accrued,
thus reducing the  Company's  interest  costs.  See "Certain  Relationships  and
Transactions - Distribution of Accrued SERP Amounts."

Tax Code Limitation on Executive Compensation Deductions


        The  Internal  Revenue  Code  imposes a $1  million  deduction  limit on
compensation  paid to the  CEO  and  the  four  other  most  highly  compensated
executive  officers  of public  companies,  subject  to certain  exceptions  for
compensation  received  pursuant to  non-discretionary  performance-based  plans
approved by such company's  shareholders.  The Company's  Variable  Compensation
Plan  and 1998  Incentive  Plan,  which  have  been  approved  by the  Company's
shareholders,  permit  variable  compensation  paid or awards or grants  made to
executives  pursuant to such plans to qualify for  deductibility by the Company.
In  addition,  executive  compensation  is  generally  structured  to attempt to
minimize the impact of the deduction limit.


        The foregoing report on executive compensation has been furnished by the
Company's MDC Committee of the Board of Directors.

                     CERTAIN RELATIONSHIPS AND TRANSACTIONS

Relationships with Related Parties

        As set forth under the caption "Security  Ownership," Harold C. Simmons,
through  Valhi and  Tremont,  may be deemed to control NL. The Company 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  which  resulted in the  acquisition  by one related
party of a publicly-held  equity interest in another related party.  The Company
from  time to time  considers,  reviews  and  evaluates,  and  understands  that
Contran,  Valhi  and  related  entities  consider,  review  and  evaluate,  such
transactions.  Depending  upon  the  business,  tax and  other  objectives  then
relevant,  including, without limitation,  restrictions under certain indentures
and other agreements of the Company,  it is possible that the Company might be a
party to one or more such  transactions  in the future.  It is the policy of the
Company to engage in transactions  with related parties on terms, in the opinion
of the Company,  no less  favorable  to the Company than could be obtained  from
unrelated parties.


        Harold C. Simmons and Glenn R. Simmons,  each a director of NL, are also
directors  and  executive  officers of Valhi and Contran.  Each of the foregoing
persons and Mr.  Martin and  General  Stafford  are  directors  of Tremont.  Mr.
Martin,  the  Company's  President  and Chief  Executive  Officer,  serves as an
executive officer and director of Tremont and TIMET.  General Stafford and Glenn
R. Simmons serve as directors of TIMET. Glenn R. Simmons also serves as Chairman
of the Board of  Keystone  and  CompX.  Mr.  Watson,  a director  and  Assistant
Secretary  of NL,  is also an  executive  officer  of  Contran  and  Valhi and a
director of Valhi, Contran,  Tremont,  TIMET, Keystone and CompX. Ms. Manix is a
director of CompX.  Mr. Garten and Mr. Watson serve as assistant  secretaries of
Tremont,  and Mr. Hardy serves as assistant treasurer of Tremont and TIMET. Such
persons  served in their  current  capacities  in 2001 and expect to continue to
serve in their current  capacities in 2002. Such  management  interrelationships
and the existing intercorporate  relationships may lead to possible conflicts of
interest.  These possible conflicts may arise from the duties of loyalty owed by
persons  acting  as  corporate  fiduciaries  of  two  or  more  companies  under
circumstances  where such  companies  may have  adverse  interests.  Mr.  Martin
devotes  approximately  one-half of his working time to NL and the  remainder of
his working time to TIMET and Tremont.  See "Certain  Contractual  Relationships
and Transactions" below.

        Although no specific  procedures  are in place that govern the treatment
of transactions among the Company,  Valhi, TIMET,  Tremont and related entities,
the boards of directors of each of the Company, Valhi, TIMET and Tremont include
one or more  members who are not  officers or directors of any other entity that
may be deemed to be  related  to the  Company.  Additionally,  under  applicable
principles  of law, in the absence of  shareholder  ratification  or approval by
directors of the Company who may be deemed disinterested, transactions involving
contracts  among the Company and any other  companies  under common control with
the Company must be fair to all companies involved.  Furthermore,  each director
and officer of the Company owes fiduciary  duties of good faith and fair dealing
with  respect to all  shareholders  of the company or  companies  for which they
serve.

Certain Contractual Relationships and Transactions

        Intercorporate Services Agreements.  The Company and Contran are parties
to an  intercorporate  services  agreement (the "Contran  ISA") whereby  Contran
makes  available to the Company (i) the services of Harold C. Simmons to consult
with the  Company  and  assist  in the  development  and  implementation  of the
Company's strategic plans and objectives, (ii) certain management, financial and
administration  services,  and  (iii)  certain  insurance  and  risk  management
services  to  the  Company,   and  the  Company   provides  to  Contran  certain
administrative support services. The services provided by Contran do not include
major corporate  acquisitions,  divestitures  and other special projects outside
the scope of the  Company's  business as it has been  conducted in the past.  NL
paid total net fees of approximately $1,195,000 in 2001 for services pursuant to
the  Contran  ISA (of  which  approximately  $950,000  was  attributable  to the
services of Mr. Simmons) and expects to pay a slightly higher amount in 2002 for
such  services.  The Company paid fees of $950,000 under the Contran ISA in each
of 2000 and 1999 attributable to the services of Mr. Simmons. The Contran ISA is
subject to automatic renewal and may be terminated by either party pursuant to a
written  notice  delivered  30 days prior to a  quarter-end.  The  Company  will
continue to pay  directors'  fees and expenses  separately to Harold C. Simmons,
Glenn R.  Simmons,  and Steven L. Watson.  See  "Compensation  of Directors  and
Executive Officers and Other Information" above.

        The  Company  and  Tremont  are  parties to an  intercorporate  services
agreement  (the  "Tremont  ISA")  whereby the Company made  available to Tremont
certain  services with respect to Tremont's tax compliance and consulting  needs
and use of the Company's corporate aircraft.  Tremont paid fees of approximately
$135,131 to the Company pursuant to the Tremont ISA during 2001. The Tremont ISA
is subject to automatic  renewal and may be terminated by either party  pursuant
to a written notice delivered 30 days prior to a quarter-end.

         The  Company  and  TIMET  are  parties  to an  intercorporate  services
agreement (the "TIMET ISA") whereby the Company made available to TIMET certain




services with respect to TIMET's tax compliance and consulting  needs and use of
the Company's  corporate  aircraft.  TIMET paid fees of  approximately  $436,358
pursuant  to the TIMET ISA during  2001.  The TIMET ISA is subject to  automatic
renewal and may be  terminated  by either  party  pursuant  to a written  notice
delivered 30 days prior to a quarter-end.

        The  Company  and  CompX  were  parties  to an  intercorporate  services
agreement  (the "CompX ISA") whereby the Company made available to CompX certain
services with respect to CompX's  occupancy,  accounting,  computer  support and
internal  audit  needs.  CompX paid fees of  approximately  $23,245 for services
pursuant to the CompX ISA during 2001. The CompX ISA was terminated in the first
quarter of 2001.

        Insurance  Sharing  Agreement.   Tall  Pines  Insurance  Company  ("Tall
Pines"),  a wholly owned captive insurance  company of Tremont,  has assumed the
obligations  of the  issuer of  certain  reinsurance  contracts  that  relate to
primary insurance policies issued by a third-party insurance company in favor of
Tremont and the Company.  The Company and Tall Pines are parties to an insurance
sharing  agreement with respect to such  reinsurance  contracts (the  "Insurance
Sharing  Agreement").  Under the terms of the Insurance Sharing  Agreement,  the
Company will  reimburse  Tall Pines with  respect to certain  loss  payments and
reserves  established  by Tall  Pines that (a) arise out of claims  against  the
Company  and its  subsidiaries  (the "NL  Liabilities"),  and (b) are subject to
payment by Tall  Pines  under its  reinsurance  contracts  with the  third-party
insurance company. Also pursuant to the Insurance Sharing Agreement,  Tall Pines
is to credit  the  Company  with  respect  to  certain  underwriting  profits or
recoveries that Tall Pines receives from  independent  reinsurers that relate to
the NL  Liabilities.  As of December 31, 2001, the Company had current  accounts
payable to Tall Pines of approximately  $552,741 with respect to such Agreement.
At  December  31,  2001,  the  Company  had  $1.7  million  of  restricted  cash
equivalents that collateralized letters of credit relating to the NL Liabilities
issued and outstanding on behalf of Tall Pines pursuant to the Insurance Sharing
Agreement.

        Insurance Matters. Tall Pines, Valmont Insurance Company ("Valmont") and
EWI RE, Inc. ("EWI,  Inc.") provide for or broker certain of the Company's,  its
joint  venture's and its  affiliates'  insurance  policies.  Valmont is a wholly
owned captive insurance  company of Valhi.  During 2001, one of the daughters of
Harold C. Simmons and a wholly owned  subsidiary of Contran  owned,  directly or
indirectly,  57.8% and 42.2%,  respectively,  of the outstanding common stock of
EWI, Inc. and of the membership interests of EWI, Inc.'s management company, EWI
RE, Ltd.  (collectively  with EWI, Inc.,  "EWI").  Through  December 31, 2000, a
son-in-law of Harold C. Simmons,  managed the  operations of EWI.  Subsequent to
December 31,  2000,  pursuant to an agreement  that  terminates  on December 31,
2002, such son-in-law provides advisory services to EWI as requested by EWI, for
which the  son-in-law  is paid  $11,875  per month and  receives  certain  other
benefits  under  EWI's  benefit  plans.   Consistent  with  insurance   industry
practices,  Tall Pines,  Valmont and EWI receive  commissions from the insurance
and reinsurance  underwriters for the policies that they provide or broker.  The
Company  and its joint  venture  paid  approximately  $10.1  million in 2001 for
policies  provided or brokered by Tall  Pines,  Valmont and EWI.  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 the Company's opinion, the amounts that the Company paid for
these insurance policies and the allocation among the Company and its affiliates
of relative  insurance  premiums are  reasonable and similar to those they could
have obtained through unrelated insurance companies and/or brokers.  The Company
expects that these relationships with Tall Pines,  Valmont and EWI will continue
in 2002.

        In January 2002, the Company  purchased EWI from its previous owners for
an aggregate cash purchase price of approximately  $9 million,  and EWI became a
wholly owned  subsidiary of the Company.  The purchase was approved by a special
committee  of  the  Company's  Board  of  Directors  consisting  of  two  of its
independent  directors,  and the purchase  price was  negotiated  by the special
committee based upon its  consideration of relevant  factors,  including but not
limited to, due diligence performed by independent  consultants and an appraisal
of  EWI  conducted  by an  independent  third  party  selected  by  the  special
committee.




        Tremont  Registration  Rights  Agreement.  In  connection  with the 1991
purchase  by Tremont of 7.8  million  shares of Common  Stock  from  Valhi,  the
Company entered into a Registration  Rights Agreement  pursuant to which Tremont
received certain  registration  rights with respect to the purchased shares. The
agreement expired in December 2001.

        Tax Sharing  Agreement.  Effective  January 1, 2001, the Company and its
qualifying  subsidiaries  will be included  in the  consolidated  United  States
federal tax return of Contran  (the  "Contran  Tax  Group").  As a member of the
Contran  Tax Group,  the  Company  is a party to a tax  sharing  agreement  (the
"Contran Tax  Agreement").  The Contran Tax Agreement  provides that the Company
compute its provision for U.S.  income taxes on a  separate-company  basis using
the tax  elections  made by Contran.  Pursuant to the Contran Tax  Agreement and
using the tax  elections  made by Contran,  the Company will make payments to or
receive  payments  from Valhi in amounts it would have paid to or received  from
the Internal  Revenue Service had it not been a member of the Contran Tax Group.
Refunds are limited to amounts  previously  paid under the Contran Tax Agreement
unless the Company  was  entitled  to a refund  from the U.S.  Internal  Revenue
Service on a  separate-company  basis.  At December 31, 2001,  the Company had a
$2.2  million  receivable  from Valhi  pursuant  to the terms of the Contran Tax
Agreement.

        Investment  in  Tremont.  During 2000 the  Company  purchased  1,000,000
shares of Tremont  Common Stock in market  transactions  for an aggregate of $26
million. Before the close of business on December 31, 2000, the Company held 16%
of the outstanding Tremont Common Stock,  including  approximately 36,000 shares
previously  held  by the  Company,  and  Valhi  held  an  additional  64% of the
outstanding  Tremont  Common  Stock.  Effective  with the close of  business  on
December  31, 2000,  the Company  contributed  substantially  all of its Tremont
Common Stock, and Valhi  contributed all of its Tremont Common Stock, to a newly
formed company,  TGI, in return for a 20% and 80% respective  ownership interest
in TGI.  After  the  contributions,  TGI held the 80% of  Tremont  Common  Stock
previously  owned  by the  Company  and  Valhi.  The  Company's  stock of TGI is
redeemable  at the option of the  Company for fair value based upon the value of
the underlying Tremont Common Stock.

        Tremont Loan Agreement.  In February 2001, NL  Environmental  Management
Services,  Inc.,  ("EMS") a  majority-owned  subsidiary  of the Company,  made a
revolving  loan of $13.4  million to  Tremont.  The amount  available  under the
revolving  loan is reduced from the original  principal  amount by $250,000 each
quarter  beginning  June 30,  2001,  bears  interest of 2% above the prime rate,
carries a  commitment  fee of 1/2 of 1% per annum of the unused  line and is due
March 31, 2003. The loan is  collateralized  by 10.2 million shares of NL Common
Stock owned by Tremont.  The creditworthiness of Tremont is dependent in part on
the  value  of the  Company  as  Tremont's  interest  in the  Company  is one of
Tremont's more  substantial  assets.  At December 31, 2001, the outstanding loan
balance was $12.7 million.

        Trust Loan  Agreement.  In May 2001,  a wholly owned  subsidiary  of EMS
loaned $20  million to the Harold C.  Simmons  Family  Trust No. 2 (the  "Family
Trust") under a $25 million revolving credit agreement. The loan was approved by
special  committees of the  Company's  and EMS's Boards of  Directors.  The loan
bears  interest at the prime rate (6% at December  31,  2001),  is due on demand
upon sixty days notice and is  collateralized by 13,749 shares, or approximately
35%, of Contran's  outstanding  Class A voting common stock and 5,000 shares, or
100%, of Contran's Series E Cumulative  preferred stock, both of which are owned
by the Family  Trust.  The value of this  collateral is dependent in part on the
value  of the  Company  as  Contran's  interest  in  the  Company,  through  its
beneficial  ownership of Valhi, is one of Contran's more substantial  assets. At
December 31, 2001,  $5 million was  available  for  additional  borrowing by the
Family  Trust.  At December  31,  2001,  the  outstanding  loan  balance was $20
million.

        Distribution  of  Accrued  SERP  Amounts.  In  2001,  the MDC  Committee
directed that the Company amend 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 the Company's  interest
costs. In connection with the amendment, the Company paid $1,761,661, $195,986,




$1,739,924,  $481,164,  and $176,692,  to Dr. Wigdor, Ms. Alderton,  and Messrs.
Martin,  Garten and Hardy,  respectively,  which  represented the accrued vested
balance in each of their SERP accounts with interest. These accrued amounts were
previously  reported as compensation in the years accrued as discussed in Note 5
to the Summary Compensation Table.


                  SHAREHOLDER PROPOSALS FOR 2002 ANNUAL MEETING

        In order to be included in the Company's  2002 Proxy  Statement and form
of proxy, shareholder proposals for the 2002 Annual Meeting of Shareholders must
be received at the principal executive offices of the Company,  16825 Northchase
Drive,  Suite 1200,  Houston,  Texas  77060,  Attention:  Mr.  David B.  Garten,
Secretary, not later than December 15, 2002. All such proposals shall be treated
in accordance with applicable rules administered by the Commission.


                  2001 ANNUAL REPORT ON FORM 10-K; HOUSEHOLDING

        A copy of the  Company's  2001 Annual Report on Form 10-K, as filed with
the Commission,  may be obtained without charge by writing:  Investor  Relations
Department,  NL Industries,  Inc., 16825 Northchase Drive, Suite 1200,  Houston,
Texas  77060.  The  Annual  Report  on Form  10-K  may also be  accessed  on the
Company's  website  at  www.nl-ind.com.  The SEC  recently  approved  a new rule
concerning  the delivery of annual  reports and proxy  statements.  It permits a
single  set of these  reports to 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. In accordance with a notice sent earlier this year
to certain beneficial  shareholders who share a single address,  only one annual
report and proxy  statement will be sent to that address unless any  stockholder
at that address gave  contrary  instructions.  However,  if any such  beneficial
stockholder  residing  at such an address  wishes to  receive a separate  annual
report or proxy statement in the future, please contact the company at the above
address or call (281) 423-3332.


                                  OTHER MATTERS

        The Board does not know of any business  except as described above which
may be presented for  consideration  at the Annual Meeting.  If any business not
described  in this  Proxy  Statement  should  properly  come  before  the Annual
Meeting,  the persons  designated as agents in the enclosed proxy card or voting
instruction  form will vote on those  matters  in  accordance  with  their  best
judgment.
