                               GENERAL INFORMATION

Shareholders  to be held on Wednesday,  May 24, 2006 and at any  adjournment  or

Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697.

     Please  refer to the  Glossary of Terms on page ii for the  definitions  of
capitalized or other terms used in this proxy statement.

                 QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

Q:   What is the purpose of the annual meeting?

A:   At the  annual  meeting,  shareholders  will  vote on the  election  of six
     directors and any other matter that may properly come before the meeting.

Q:   How does the board recommend that I vote?

A:   The board of  directors  recommends  that you vote FOR each of the nominees
     for director.

Q:   Who is allowed to vote at the annual meeting?

A:   The board of  directors  has set the close of business on March 28, 2006 as
     the record date for the determination of shareholders entitled to notice of
     and to vote at the  meeting.  Only holders of record of our common stock as
     of the close of  business  on the record  date are  entitled to vote at the
     meeting.  On the record  date,  48,563,034  shares of our common stock were
     issued and  outstanding.  Each share of our common stock is entitled to one
     vote.

Q:   How do I vote?

A:   If your  shares  are held by a bank,  broker  or other  nominee  (i.e.,  in
     "street name"),  you must follow the instructions  from your nominee on how
     to vote your shares.

     If   you are a shareholder of record, you may:

     o    vote in person at the annual meeting; or

     o    instruct the agents named on the proxy card how to vote your shares by
          completing,  signing  and  mailing  the  enclosed  proxy  card  in the
          envelope provided.

     If you  execute a proxy  card but do not  indicate  how you would like your
     shares voted for one or more of the nominees,  the agents will vote FOR the
     election of each such  nominee for director  and, to the extent  allowed by
     applicable  law, in the  discretion  of the agents on any other matter that
     may properly come before the meeting.

Q:   Who will count the votes?

A:   The board of directors has appointed Computershare,  our transfer agent and
     registrar,  to receive proxies and ballots,  ascertain the number of shares
     represented,  tabulate  the vote and serve as inspector of election for the
     meeting.

Q:   Is my vote confidential?

A:   Yes.  All  proxy  cards,  ballots  or  voting  instructions   delivered  to
     Computershare will be kept confidential in accordance with our by-laws.

Q:   May I change or revoke my proxy or voting instructions?

A:   If you are a  shareholder  of record,  you may change or revoke  your proxy
     instructions at any time before the meeting in any of the following ways:

     o    delivering to Computershare a written revocation;

     o    submitting another proxy card bearing a later date; or

     o    voting in person at the meeting.

     If your shares are held by a bank, broker or other nominee, you must follow
     the  instructions  from your nominee on how to change or revoke your voting
     instructions.

Q:   What constitutes a quorum?

A:   A quorum  is the  presence,  in person or by  proxy,  of the  holders  of a
     majority of the outstanding  shares of our common stock entitled to vote at
     the meeting. Under the applicable rules of the NYSE and the SEC, brokers or
     other  nominees  holding  shares of record on behalf of a client who is the
     actual  beneficial  owner of such shares are  authorized to vote on certain
     routine matters without receiving instructions from the beneficial owner of
     the shares.  If such a broker/nominee  who is entitled to vote on a routine
     matter  delivers  an  executed  proxy card and does not vote on the matter,
     such a vote is referred  to in this proxy  statement  as a  "broker/nominee
     non-vote."  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.

Q:   What vote is  required  to elect a director  nominee  or approve  any other
     matter?

A:   If a quorum is present, a plurality of the affirmative votes of the holders
     of our  outstanding  shares of common stock  represented and entitled to be
     voted at the meeting is necessary to elect each nominee for  director.  The
     accompanying  proxy card or voting  instruction form provides space for you
     to withhold authority to vote for any of the nominees. 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.  However,  since director nominees need only receive the
     plurality  of the  affirmative  votes  from  the  holders  represented  and
     entitled  to vote at the  meeting to be  elected,  a vote  withheld  from a
     particular nominee will not affect the election of such nominee.

     Except  as our  amended  and  restated  certificate  of  incorporation  and
     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  votes of the  holders  of a majority  of the  outstanding
     shares  represented  and  entitled  to vote at the  meeting.  Shares of our
     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.

Q:   Who will pay for the cost of soliciting the proxies?

A:   We will pay all expenses related to the solicitation, including charges for
     preparing, printing, assembling and distributing all materials delivered to
     shareholders.  In  addition to the  solicitation  by mail,  our  directors,
     officers  and regular  employees  may solicit  proxies by  telephone  or in
     person for which such persons will receive no additional  compensation.  We
     have retained The Altman  Group,  Inc. to aid in the  distribution  of this
     proxy statement and related materials at an estimated cost of $1,200.  Upon
     request,   we  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 our  common  stock  that  such
     entities hold of record.

                               CONTROLLED COMPANY

     Valhi directly held  approximately  83.1% of the outstanding  shares of our
common stock as of the record date.  Valhi has  indicated  its intention to have
its shares of our common  stock  represented  at the  meeting  and voted FOR the
election of each of the director  nominees to our board of  directors.  If Valhi
attends  the meeting in person or by proxy and votes as  indicated,  the meeting
will have a quorum present and the  shareholders  will elect all the nominees to
the board of directors.

     Because of Valhi's  ownership  of our common  stock,  we are  considered  a
controlled  company  under the listing  standards  of 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.  We have chosen not to
have a  majority  of  independent  directors  or an  independent  nominating  or
corporate  governance  committee.  Our board of directors believes that the full
board of directors best represents the interests of all of our  shareholders 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 NYSE director independence standards, the board
of directors has determined that three of our directors are independent and have
no  material  relationship  with us other  than  serving as our  directors.  See
"Meetings and Committees of the Board of Directors--Audit Committee" for certain
relationships  the board of directors  considered in making this  determination.
While the  members of our  management  development  and  compensation  committee
currently satisfy the independence  requirements of the NYSE, we have 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  "Shareholder  Proposals  and
Director  Nominations  for the 2007 Annual  Meeting"  for a  description  of our
policies and procedures for shareholder nominations of directors.






                              ELECTION OF DIRECTORS

     Our amended and restated  certificate  of  incorporation  provides that the
board of directors shall consist of not less than seven nor more than 17 members
as determined by our board of directors or shareholders.  Our board of directors
has currently set the number of directors at seven and  recommended six director
nominees for the 2006 annual meeting. The board of directors has determined that
it can adequately  represent our shareholders with six directors and one vacancy
on the board of  directors.  Even  though  there is  currently  a vacancy of one
directorship on the board of directors,  you cannot vote for a greater number of
persons than the six director  nominees set forth in this proxy  statement.  The
directors  elected at the meeting will hold office until our 2007 Annual Meeting
of  Shareholders  and until their  successors  are duly elected and qualified or
their earlier removal, resignation or death.

     All of the nominees are currently  members of our board of directors  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, all shares
represented  by a proxy  card  will be  voted  FOR an  alternate  nominee  to be
selected by the board of directors,  unless the shareholder executing such proxy
card  withholds  authority  to vote for such  nominee.  The  board of  directors

                MEETINGS AND COMMITTEES OF THE BOARD OF DIRECTORS

     The board of  directors  held  three  meetings  and took  action by written
consent on three occasions in 2005. Other than Harold C. Simmons,  each director
participated  in all of such meetings and of the 2005 meetings of the committees
on which he served  at the time.  Mr.  Simmons  participated  in 67% of our 2005
board  meetings.  It is  expected  that each  director  will  attend  our annual
meetings of shareholders,  which are held immediately before the annual meetings
of the board of  directors.  All members of the board of directors  attended our
2005 annual shareholder meeting.

     The board of  directors  has  established  and  delegated  authority to two
standing  committees,  which are  described  below.  The board of  directors  is
expected  to elect  the  members  of the  standing  committees  at the  board of
directors annual meeting immediately  following the annual shareholder  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.

     Audit Committee.  Our audit committee  assists with the board of directors'
oversight  responsibilities  relating to our financial  accounting and reporting
processes and auditing  processes.  The  responsibilities of our audit committee
are more  specifically  set forth in the amended and  restated  audit  committee
charter,  a copy of which is attached as Exhibit A to this proxy  statement  and
also  available  under  the  corporate   governance   section  of  our  website,
www.nl-ind.com.  Applying the requirements of the NYSE listing standards and SEC
regulations, as applicable, the board of directors has determined that:

     o    each  member  of  our  audit  committee  is  independent,  financially
          literate and has no material  relationship  with us other than serving
          as our director; and

     o    Mr. Cecil H. Moore, Jr. is an "audit committee financial expert."

     In determining that Mr. Worrell,  a member of our audit  committee,  has no
material  relationship with us other than serving as our director,  the board of
directors considered the following relationship.

     o    As part of a five-year  pledge of $5.0  million,  the  Foundation,  of
          which Harold C. Simmons is the chairman of the board,  contributed  in
          each of 2004 and 2005 $1.0 million to Children's Medical Foundation of
          Texas, of which foundation Mr. Worrell serves as a trustee.

The  board  determined  that this  relationship  was not  material  based on the
representation  from Mr. Worrell that he receives no compensation for serving as
a trustee of Children's Medical Foundation of Texas.

     No member of our audit  committee  serves on more than three public company
audit  committees.  For further  information on the role of our audit committee,
see "Audit  Committee  Report." The current  members of our audit  committee are
Thomas P. Stafford  (chairman),  Cecil H. Moore,  Jr. and Terry N. Worrell.  Our
audit committee held 17 meetings in 2005.

     Management   Development   and   Compensation   Committee.   The  principal
responsibilities of our management development and compensation committee are:

     o    to recommend  to the board of directors  whether or not to approve any
          proposed charge to us or any of our wholly owned subsidiaries pursuant
          to an ISA with a related parent company;

     o    to  review,  approve  or  administer  certain  matters  regarding  our
          employee benefit plans or programs;

     o    to  review,  approve,  administer  and grant  awards  under our equity
          compensation plans; and

     o    to review and administer such other compensation  matters as the board
          of directors may direct from time to time.

     As discussed  above with respect to audit committee  members,  the board of
directors has  determined  that each member of our  management  development  and
compensation committee is independent by applying the NYSE director independence
standards. For further information on the role of our management development and
compensation committee, see "Executive Compensation Report." The current members
of our management  development and compensation committee are Thomas P. Stafford
(chairman) and Terry N. Worrell.  Our management  development  and  compensation
committee held one meeting in 2005.

                COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS
                              AND OTHER INFORMATION

     Compensation  of  Directors.  In 2005,  our  directors  received  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 our board of  directors or its  committees.  The
chairman of our audit  committee and any member of our audit  committee whom the
board  identified as an "audit committee  financial  expert" for purposes of the
annual proxy statement received an annual retainer of $10,000, paid in quarterly
installments  (provided  that if one person served in both  capacities  only one
such retainer was paid),  and other members of our audit  committee  received an
annual  retainer  of  $5,000,  paid  in  quarterly  installments.  If one of our
directors  dies  while  serving  on  our  board  of  directors,  his  designated
beneficiary  or estate will be entitled to receive a death  benefit equal to the
annual  retainer  then in effect.  We reimburse  our  directors  for  reasonable
expenses incurred in attending meetings and in the performance of other services
rendered on behalf of our board of  directors  or its  committees.  In addition,
Gen.  Stafford  (ret.)  receives an annual payment of $15,000 as a result of his
service on our board of directors prior to 1987.

     On the day of  each  annual  shareholder  meeting,  each  of our  directors
receives a grant of shares of our common stock as  determined  by the  following
formula based on the closing price of a share of our common stock on the date of
such meeting.

       Range of Closing Price Per                    Shares of Common
       Share on the Date of Grant                  Stock to Be Granted
       --------------------------                  -------------------
         Under $5.00                                       2,000
         $5.00 to $9.99                                    1,500
         $10.00 to $20.00                                  1,000
         Over $20.00                                         500

     As a result of the $15.37 per share  closing  price of our common  stock on
May 19,  2005,  the date of our 2005  annual  shareholder  meeting,  each of our
directors  elected on that date  received a grant of 1,000  shares of our common
stock.

          specifically  identifiable  to  a  particular  officer  and  were  not
          allocable  between Kronos Worldwide and KII. In 2004 and 2005, the ISA
          charges to Kronos Worldwide were  identifiable to each named executive
          officer and include amounts allocable to KII.

     (c)  Includes  amounts  allocated to EWI Re, Inc.,  one of our wholly owned
          subsidiaries, under the ISA between Contran and NL.





     No Grants of Stock Options or Stock Appreciation Rights. Neither we nor any
of our parent or  subsidiary  corporations  granted  any stock  options or stock
appreciation rights to our named executive officers during 2005.

                         CORPORATE GOVERNANCE DOCUMENTS

     Code of Business  Conduct and  Ethics.  We have  adopted a code of business
conduct and ethics that applies to all of our directors, officers and employees,
including  our  principal   executive  officer,   principal  financial  officer,
principal  accounting  officer and  controller.  Only the board of directors may
amend the code.  Only our audit  committee  or other  committee  of the board of
directors with specific delegated  authority may grant a waiver of this code. We
will  disclose  amendments  to or waivers of the code as required by law and the
applicable rules of the NYSE.

     Corporate  Governance  Guidelines.  We have  adopted  corporate  governance
guidelines to assist the board of directors in exercising its  responsibilities.
Among other things,  the corporate  governance  guidelines  provide for director
qualifications,  for independence  standards and responsibilities,  for approval
procedures  for ISAs  and that our  audit  committee  chairman  presides  at all
meetings of the non-management or independent directors.

     Audit  Committee  Charter.  We have adopted an amended and  restated  audit
committee charter under which our audit committee operates.  Among other things,
our audit  committee  charter  provides the purpose,  authority,  resources  and
responsibilities of the committee.

     A copy of each of these three documents,  among others, is available on our
website at www.nl-ind.com  under the corporate governance section. A copy of the
amended and restated  audit  committee  charter is also attached as Exhibit A to
this proxy statement.  In addition,  any person may obtain a copy of these three
documents  without charge,  by sending a written request to the attention of our
corporate  secretary at NL  Industries,  Inc.,  Three Lincoln  Centre,  5430 LBJ
Freeway, Suite 1700, Dallas, Texas 75240-2697.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section  16(a)  of the  Securities  Exchange  Act  requires  our  executive
officers,  directors and persons who own more than 10% of a registered  class of
our equity  securities  to file reports of ownership  with the SEC, the NYSE and
us. Based  solely on the review of the copies of such forms and  representations
by certain reporting persons,  we believe that for 2005 our executive  officers,
directors and 10% shareholders  complied with all applicable filing requirements
under  section  16(a) except that after its formation in August 2005 as a parent
company of Valhi, VHC failed to file timely its Form 3.

                          EXECUTIVE COMPENSATION REPORT

     During  2005,  our  management   development  and  compensation   committee
administered  certain  matters  regarding  the  compensation  of  our  executive
officers.

NL ISA

     During 2005, we paid certain fees to Contran for services provided pursuant
to an ISA between Contran and us. Such services provided under this ISA included
the services of all of our executive officers.

     Contran  annually  determines  the  aggregate  fee to  charge  us  and  our
privately held subsidiaries based on the following:

     o    an estimate of the amount of time each Contran  employee that performs
          services for us and certain of our privately  held  subsidiaries  will
          spend on such services over the year; and

     o    Contran's cost related to such employee, which includes the employee's
          base salary,  incentive  compensation  and an overhead  component that
          takes into account other employment costs, including medical benefits,
          unemployment  and  disability  insurance  and pension  costs and other
          costs of providing an office,  equipment  and supplies  related to the
          provision of such services.

     The  portion  of the  annual  charge we pay under  the ISA  between  us and
Contran for the services of any particular  individual is capped at $1.0 million
in the aggregate to enhance our ability to deduct such charge for federal income
tax purposes.  The amount of the fee we paid in 2005 under this ISA for a person
who provided  services to us or our privately held subsidiaries  represents,  in
management's  view,  the  reasonable   equivalent  of  "compensation"  for  such
services.  It is also management's view that the proposed aggregate charge to us
under this ISA is fair to us and our  shareholders and the cost for the services
provided under the ISA would be no less favorable to us than could  otherwise be
obtained from an unrelated  third party for  comparable  services.  See "Certain
Relationships  and  Transactions--Intercorporate  Services  Agreements"  for the
aggregate  amount we paid to  Contran  in 2005  under  this ISA.  For each named
executive  officer,  the portion of the annual charge we paid in 2005 to Contran
under this ISA  attributable  to the services of such  executive  officer is set
forth in footnote (2) to the summary compensation table in this proxy statement.
The  amounts  charged  under  this  ISA are not  dependent  upon  our  financial
performance.

     For 2005, our management  development and compensation  committee  reviewed
documentation  and discussed with management  Contran's ISA allocation  process,
including how Contran determined the necessary  personnel,  the estimated number
of full time  employees  that would be required to provide the  services and the
cost of such services  under this ISA. The committee then  recommended  that our
board of directors  approve the 2005  aggregate  service charge for the proposed
Contran  services  to be  rendered  to us  and  certain  of our  privately  held
subsidiaries under the ISA after concluding that:

     o    the cost to employ the additional  personnel  necessary to perform the
          quality of the services  provided by Contran would exceed the proposed
          2005 aggregate fee to be charged by Contran under this ISA; and

     o    the cost for such  services  would  be no less  favorable  than  could
          otherwise  be obtained  from an unrelated  third party for  comparable
          services.

Upon receiving the recommendation of our management development and compensation
committee that the ISA charge to us and our privately held subsidiaries was fair
and reasonable to us and our  shareholders and that it was in our best interests
to  continue  receiving  such  services  presently  provided  by  Contran,   our
independent  directors,  with our other directors abstaining,  approved the 2005
aggregate charge to us under this ISA.

     In making these determinations, our management development and compensation
committee  relied on their  collective  business  experience  and judgment.  The
committee  did not  review  any  2005 ISA  charges  from  Contran  to any of our
publicly held subsidiaries or their subsidiaries, which charges were reviewed by
the management development and compensation committee of the applicable publicly
held subsidiary.

Common Stock Based Compensation

     In 2005, our management development and compensation committee administered
matters regarding the common stock based compensation of our executive officers.
In 2005,  management did not recommend any common stock based compensation,  and
our management  development  and  compensation  committee did not grant any such
compensation  to any  executive  officers  other than annual stock grants to our
directors,  including  our  chief  executive  officer,  for  their  services  as
directors.  Our  management  development  and  compensation  committee  does not
currently  anticipate granting common stock based compensation to anyone in 2006
other than these annual grants of stock to our directors.  See  "Compensation of
Directors  and  Executive  Officers and Other  Information  --  Compensation  of
Directors."

Deductibility of Compensation

     Section 162(m) of the Internal  Revenue Code of 1986 generally  disallows a
tax deduction to public companies for  non-performance  based  compensation over
$1.0 million paid to the company's chief  executive  officer and four other most
highly compensated executive officers. It is our general policy to structure the
performance-based  portion of the  compensation  of our executive  officers in a
manner that enhances our ability to deduct fully such compensation.

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

  Thomas P. Stafford                        Terry N. Worrell
  Chairman of our Management Development    Member of our Management Development
  and Compensation Committee                and Compensation Committee






                     CERTAIN RELATIONSHIPS AND TRANSACTIONS

     Relationships   with  Related   Parties.   As  set  forth  under  "Security
Ownership," Harold C. Simmons,  through Contran, may be deemed to control us. We
and other  entities  that may be deemed to be  controlled  by or  related to Mr.
Simmons sometimes engage in the following:

     o    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

     o    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
          an equity interest in another related party.

     We periodically  consider,  review and evaluate and understand that Contran
and  related   entities   periodically   consider,   review  and  evaluate  such
transactions.  Depending  upon  the  business,  tax and  other  objectives  then
relevant and restrictions under indentures and other agreements,  it is possible
that we might be a party to one or more of such  transactions in the future.  In
connection with these  activities,  we may consider  issuing  additional  equity
securities or incurring additional indebtedness. Our acquisition activities have
in the  past and may in the  future  include  participation  in  acquisition  or
restructuring  activities  conducted by other companies that may be deemed to be
related to Harold C. Simmons.  It is our policy to engage in  transactions  with
related parties on terms, in our opinion,  no less favorable to us than could be
obtained from unrelated parties.

     Certain directors or executive officers of Contran, CompX, Keystone, Kronos
Worldwide,  TIMET or Valhi also serve as our  directors or  executive  officers.
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 us and our  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  shareholder  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 shareholders of the companies for which they serve.

     Intercorporate  Services Agreements.  We and certain related companies have
entered  into ISAs.  Under the ISAs,  employees of one company  provide  certain
services,  including  executive officer services,  to the other company on a fee
basis. The services rendered under the ISAs may include  executive,  management,
financial,  internal audit, accounting,  tax, legal, insurance, risk management,
treasury,  aviation,  human resources,  technical,  consulting,  administrative,
office,  occupancy  and  other  services  as  required  from time to time in the
ordinary course of the recipient's business.  The fees paid pursuant to the ISAs
are  generally  based upon an estimate of the time  devoted by  employees of the
provider of the services to the affairs of the recipient and the employer's cost
related to such employees,  which includes the employees' cash  compensation and
an overhead component that takes into account the employer's other costs related
to the  employees.  Each  of  the  ISAs  in  their  current  form  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.  Because of the large number of companies related to Contran and us, we
believe we benefit from cost savings and economies of scale gained by not having
certain  management,  financial  and  administrative  staffs  duplicated at each
entity,  thus  allowing  certain  individuals  to provide  services  to multiple
companies but only be compensated by one entity. With respect to a publicly held
company  that is a party to an ISA,  the ISA and the  related  aggregate  annual
charge is approved by the independent directors of the company after receiving a
recommendation  from  the  company's  management  development  and  compensation
committee.

     The following  table  describes the fees paid by us, our  subsidiaries  and
Kronos  Worldwide  to Contran in 2005 and the amount  anticipated  to be paid to
Contran in 2006 for services Contran  provided us or our subsidiaries  under the
various ISAs.

(1)      In addition to the reported ISA charges, we and Kronos Worldwide also
         pay Messrs. Glenn and Harold Simmons and Watson for their services as
         directors.
(2)      In addition to the reported ISA charges, CompX also pays Messrs. Glenn
         Simmons and Watson for their services as directors of CompX.

     Short-Swing Trading Profits. From December 2004 through April 2005, we sold
shares of  Kronos  Worldwide  common  stock in the open  market.  From June 2004
through October 2005, Valhi purchased shares of Kronos Worldwide common stock in
the open  market.  Pursuant to section  16(b) of the  Securities  Exchange  Act,
certain of such sales and  purchases  might be deemed to be matched for purposes
of computing  short-swing  profits.  As a result,  Valhi made several  voluntary
payments  to  Kronos  Worldwide   concurrently   with  a  potentially   matching
transaction  aggregating  approximately  $600,000  and $1.2 million for 2004 and
2005,  respectively,  which amounts represent the maximum amount of any possible
short-swing profits resulting from these transactions.

     Loans between  Related  Parties.  In 2001, a wholly owned  subsidiary of NL
Environmental  Management  Services,  Inc., a wholly owned  subsidiary  of ours,
loaned  $20  million  to the  Harold  C.  Simmons  Family  Trust  No. 2, a trust
established for the benefit of certain  children and  grandchildren of Harold C.
Simmons of which Mr. Simmons is the sole trustee,  under a $25 million revolving
credit  agreement.  Special  independent  committees of our and NL Environmental
Management Services, Inc.'s boards of directors approved the loan. The loan bore
interest  at the prime  rate,  was due on demand  with sixty days notice and was
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 Harold C.  Simmons
Family  Trust No. 2. The value of this  collateral  is  dependent in part on our
value as Contran's  interest in us is one of Contran's more substantial  assets.
In 2005,  the trust fully repaid the loan with payments of  approximately  $10.5
million of  principal  and  interest  and the  revolving  credit  agreement  was
terminated in October 2005.

     From time to time, other loans and advances are made between us and various
related parties pursuant to term and demand notes.  These loans and advances are
entered into  principally  for cash management  purposes.  When we loan 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 us, we believe that we have
evaluated the credit risks  involved,  and that those risks are  reasonable  and
reflected  in the terms of the  applicable  loans.  When we borrow from  related
parties, we are generally able to pay a lower rate of interest than we would pay
if we borrowed from unrelated parties.

     Interest  income on all loans to  unconsolidated  related  parties was $0.5
million  in  2005,  which  represents  interest  earned  on  the  loan  from  NL
Environmental  Management  Services,  Inc. to the Harold C. Simmons Family Trust
No.  2. We did not incur  any  interest  expense  on loans  from  unconsolidated
related parties in 2005.

     Formation of CompX Group,  Inc.  Subsequent to our acquisition in September
2004 of 68.4% of the then  outstanding  shares of CompX  common  stock  owned by
Valhi  and  its  wholly  owned  subsidiary,  Valcor,  Inc.,  and  pursuant  to a
subscription  agreement, we and TFMC capitalized CGI by each contributing to CGI
68.4% and 14.6%,  respectively,  of the then outstanding  shares of CompX common
stock.  As a result of this  initial  contribution,  we and TFMC held  82.4% and
17.6% of the  outstanding  shares of common stock of CGI,  respectively.  In the
subscription  agreement,  CGI agreed that it would not sell any of the shares of
CompX  common  stock  contributed  to CGI by TFMC  without the  express  written
consent of TFMC. In addition, in accordance with the subscription agreement, the
parties entered into a voting agreement that provides,  among other things, that
we will elect one nominee of TFMC to CGI's five member board of directors.

     Pursuant to CGI's certificate of incorporation, upon the written request of
a CGI stockholder,  CGI is obligated to redeem such number of the  stockholder's
shares of CGI common stock that the stockholder requests. The CGI stockholder is
also entitled to elect to receive as part of the redemption price such number of
shares of CompX class A or class B common stock that the holder  contributed  to
CGI  based  on the  same  ratio  of  shares  of  CGI  received  in  the  initial
contribution.  CGI's board of directors  is then  obligated to determine in good
faith and in its best business judgment the redemption price.  Pursuant to CGI's
certificate of incorporation,  in determining the redemption price, the board of
directors shall value each share of CompX common stock held by CGI at the volume
weighted average sale price of a share of CompX class A common stock for the ten
trading days ending on the day CGI receives the redemption request.

     With the  initial  capitalization  of CGI,  CompX  became  eligible to file
consolidated  returns of U.S.  federal  income  taxes with us and  Contran.  See
"--Tax Matters" below for a discussion of this relationship with us and Contran.

     Insurance Matters. We and Contran participate in a combined risk management
program.  Pursuant to the program,  Contran and certain of its  subsidiaries and
related  entities,  including  us and  certain of our  subsidiaries  and related
entities,  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 and EWI RE, Inc.  provide for or broker  these  insurance
policies.  Tall Pines is a captive  insurance company wholly owned by Valhi, and
EWI RE, Inc. is reinsurance  brokerage and risk  management firm wholly owned by
us. Consistent with insurance  industry  practices,  Tall Pines and EWI RE, Inc.
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 related companies,  including
us, have entered into a loss sharing agreement under which any uninsured loss is
shared by those companies who have submitted  claims under the relevant  policy.
We believe 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.

     During 2005, we, CompX and Kronos  Worldwide paid premiums of approximately
$10.0  million  for  insurance  policies  Tall Pines  provided  or EWI RE,  Inc.
brokered,  including  approximately  $1.3  million  paid  by  Louisiana  Pigment
Company,  L.P.,  a  partnership  of which a wholly  owned  subsidiary  of Kronos
Worldwide  and a  subsidiary  of  Huntsman  LLC  each  own  50%.  These  amounts
principally  included  payments for reinsurance  and insurance  premiums paid to
unrelated third parties,  but also included  commissions  paid to Tall Pines and
EWI RE, Inc. Tall Pines purchases reinsurance for substantially all of the risks
it  underwrites.  In our  opinion,  the amounts  that we, our  subsidiaries  and
Louisiana  Pigment  Company,  L.P.  paid for these  insurance  policies  and the
allocation among us and our related entities of relative  insurance premiums are
reasonable  and at least as  favorable  to those we or they could have  obtained
through  unrelated   insurance  companies  or  brokers.  We  expect  that  these
relationships with Tall Pines and EWI RE, Inc. will continue in 2006.

     Tax  Matters.  We  and  our  qualifying  subsidiaries  are  members  of the
consolidated  U.S.  federal tax return of which  Contran is the parent  company,
which we refer to as the  "Contran  Tax  Group." As a member of the  Contran Tax
Group and  pursuant to certain tax sharing  agreements,  each of the members and
its  qualifying  subsidiaries  compute  provisions  for U.S.  income  taxes on a
separate company basis using tax elections made by Contran.  Pursuant to the tax
sharing agreements and using tax elections made by Contran,  each of the parties
makes payments or receives payments in amounts it would have paid to or received
from the U.S.  Internal  Revenue Service had it not been a member of the Contran
Tax Group but  instead  had been a  separate  taxpayer.  Refunds  are  generally
limited to amounts  previously paid under the respective tax sharing  agreement.
We and our qualifying  subsidiaries  are also a part of consolidated tax returns
filed  by  Contran  in  certain  U.S.  state  jurisdictions.  The  terms  of the
applicable  tax  sharing  agreements  also  apply  to  state  payments  to these
jurisdictions.

     Under  applicable law, we, as well as every other member of the Contran Tax
Group,  are each jointly and severally  liable for the aggregate  federal income
tax liability of Contran and the other  companies  included in the group for all
periods in which we are  included in the group.  Valhi has agreed,  however,  to
indemnify  us for any  liability  for income  taxes of the  Contran Tax Group in
excess of our tax  liability  previously  computed and paid by us in  accordance
with the tax allocation policy.

     Prior to December 2003,  Kronos  Worldwide was a wholly owned subsidiary of
ours.  In  December  2003,  in  conjunction  with a  recapitalization  of Kronos
Worldwide,  we  completed  the  distribution  of  approximately  48.8% of Kronos
Worldwide's  common  stock on a pro rata  basis to our  shareholders  (including
Valhi and  Tremont).  Our  shareholders  received one share of Kronos  Worldwide
common stock for every two shares of our common stock held.  During 2004 and the
first quarter of 2005, we paid an aggregate of five  quarterly  dividends in the
form of  shares  of  Kronos  Worldwide  common  stock in which an  aggregate  of
approximately  1.5  million  shares of Kronos  Worldwide  common  stock (3.0% of
Kronos  Worldwide's  outstanding shares of common stock) were distributed to our
shareholders in the form of pro rata dividends.

     Our 2003, 2004 and 2005  distributions  of shares of common stock of Kronos
Worldwide  were  taxable  to us and we  were  required  to  recognize  such  tax
liability for financial reporting  purposes.  On November 30, 2004, we and Valhi
agreed to pay Valhi the tax liability  generated from the distribution of shares
of  Kronos  Worldwide  common  stock to Valhi  and  Tremont,  including  the tax
liability  related to such shares  distributed  to Valhi and Tremont in December
2003 and the tax liability related to the shares distributed to Valhi during all
of 2004. We and Valhi further  agreed that in lieu of a cash income tax payment,
such tax liability  could be paid by us to Valhi in the form of shares of Kronos
Worldwide  common  stock.  Such tax  liability  related  to the shares of Kronos
Worldwide  common  stock  distributed  to Valhi  and  Tremont  in 2003 and 2004,
including the tax liability  resulting from the use of Kronos  Worldwide  common
stock  to  settle  such  liability,   aggregated   approximately  $227  million.
Accordingly,  in the fourth  quarter of 2004 we  transferred  approximately  5.5
million shares of Kronos Worldwide common stock to Valhi in satisfaction of such
tax  liability  and the tax  liability  generated  from  the use of such  Kronos
Worldwide  shares to settle such tax  liability.  In agreeing to settle such tax
liability with such 5.5 million  shares of Kronos  Worldwide  common stock,  the
Kronos  Worldwide  shares were valued at an agreed-upon  price of $41 per share.
Kronos  Worldwide's  average  closing market price during the months of November
and December 2004 was $41.53 and $41.77, respectively. The tax liability related
to the shares of Kronos  Worldwide  distributed to Valhi in the first quarter of
2005 aggregated  $3.0 million,  and we paid such tax liability to Valhi in cash.
Such  income tax  liabilities  will become  payable by Valhi to Contran,  and by
Contran to the  applicable  tax  authority  when the shares of Kronos  Worldwide
common stock  transferred  or distributed by us to Valhi and Tremont are sold or
otherwise  transferred  outside the Contran Tax Group or in the event of certain
restructuring transactions involving us and Valhi.

     Under certain circumstances, tax regulations could require Contran to treat
items  differently  than we would have treated  them on a stand alone basis.  In
such instances, accounting principles generally accepted in the United States of
America  require us to conform to Contran's  tax  elections.  In addition to the
$3.0 million payment from us to Valhi  discussed  above, in 2005 pursuant to the
tax sharing  agreements,  we paid approximately $1.7 million in cash, and Kronos
Worldwide paid approximately $7.7 million in cash, to Valhi.

     Simmons  Family  Matters.  Certain  family  members of our  chairman of the
board,  Harold  C.  Simmons,  provide  services  to  us  and  our  subsidiaries,
including, CompX and Kronos Worldwide,  pursuant to certain ISAs. In 2005, Glenn
R.  Simmons,  our  chairman's  brother,  and James C.  Epstein,  our  chairman's
son-in-law,   provided   certain   executive  and  risk   management   services,
respectively,  to us and our  subsidiaries  pursuant to ISAs. The portion of the
fees we and our subsidiaries  paid to Contran in 2005 pursuant to these ISAs for
the  services  of each of Messrs.  Glenn  Simmons  and  Epstein  was $56,500 and
$140,200,  respectively.  We and our subsidiaries  expect to pay Contran similar
amounts for these services in 2006.  Mr. Glenn Simmons also received  additional
aggregate  compensation  of  approximately  $115,500  in cash and stock from us,
CompX and  Kronos  Worldwide  for his  services  as a  director  for 2005 and is
expected to continue to receive similar  compensation for 2006. In 2005, he also
realized  an  aggregate  of  approximately  $13,000  from the  exercise of stock
options we and CompX had granted him.

                             AUDIT COMMITTEE REPORT

     Our  audit  committee  of the  board of  directors  is  comprised  of three
directors and operates under a written  amended and restated  charter adopted by
the board of directors. All members of our 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 amended and restated  audit
committee  charter  is  attached  as  Exhibit  A to this  statement  and is also
available  on our  website  at  www.nl-ind.com  under the  corporate  governance
section.

     Our  management  is  responsible  for,  among other  things,  preparing its
consolidated  financial  statements in  accordance  with  accounting  principles
generally accepted in the United States of America, or "GAAP,"  establishing and
maintaining  internal control over financial reporting (as defined in Securities
Exchange Act Rule 13a-15(f)) and evaluating the  effectiveness  of such internal
control over financial reporting.  Our independent  registered public accounting
firm is  responsible  for  auditing our  consolidated  financial  statements  in
accordance with the standards of the Public Company  Accounting  Oversight Board
(United States) and for expressing an opinion on the conformity of the financial
statements with GAAP. Our independent  registered public accounting firm is also
responsible  for  auditing  our internal  control  over  financial  reporting in
accordance with such standards and for expressing an opinion on (i) management's
assessment of the effectiveness of its internal control over financial reporting
and (ii) the effectiveness of its internal control over financial reporting. Our
audit committee assists the board of directors in fulfilling its  responsibility
to oversee  management's  implementation of our financial  reporting process. In
its  oversight  role,  our audit  committee  reviewed and  discussed the audited
financial  statements with  management and with PwC, our independent  registered
public accounting firm for 2005. Our audit committee also reviewed and discussed
internal control over financial reporting with management and with PwC.

     Our  audit   committee  met  with  PwC  and  discussed  any  issues  deemed
significant by our independent  registered public accounting firm, including the
required  matters to be discussed by  Statement  of Auditing  Standards  No. 61,
Communication  with Audit Committee,  as amended.  PwC has provided to our audit
committee written disclosures and the letter required by Independence  Standards
Board No. 1,  Independence  Discussions  with  Audit  Committees,  and our audit
committee discussed with PwC that firm's independence.  Our audit committee also
concluded  that PwC's  provision  of  non-audit  services  to us and our related
entities is compatible with PwC's independence.

     Based upon the foregoing considerations, our audit committee recommended to
the board of directors that our audited financial  statements be included in our
2005 Annual Report on Form 10-K for filing with the SEC.

     Members  of our  audit  committee  of the board of  directors  respectfully
submit the foregoing report.

              INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM MATTERS

     Independent   Registered   Public   Accounting  Firm.  PwC  served  as  our
independent  registered  public  accounting firm for the year ended December 31,
2005.  Our audit  committee has appointed PwC to review our quarterly  unaudited
consolidated  financial  statements to be included in our  Quarterly  Reports on
Form 10-Q for the first three quarters of 2006. We expect PwC will be considered
for  appointment  to audit our  annual  consolidated  financial  statements  and
internal control over financial reporting for the year ending December 31, 2006.
Representatives of PwC are not expected to attend the annual meeting.

     Fees Paid to  PricewaterhouseCoopers  LLP.  The  following  table shows the
aggregate fees that PwC has billed or is expected to bill to us, CompX or Kronos
Worldwide  for  services  rendered  for 2004 and 2005 that our  audit  committee
authorized  for us and our privately held  subsidiaries  and the CompX or Kronos
Worldwide audit  committees  each separately  authorized for its corporation and
such corporation's  privately held subsidiaries.  Additional audit fees for 2005
may  subsequently  be  authorized  and paid to PwC,  in which  case the  amounts
disclosed  below for fees paid to PwC for 2005 would be adjusted to reflect such
additional  payments  in our proxy  statement  relating  to next  year's  annual
shareholder  meeting.  In this regard,  the audit fees shown below for 2004 have
been  adjusted  from amounts  disclosed in our proxy  statement  for last year's
annual shareholder meeting.

     of CompX's Thomas Regout  operations in Europe and research and development
     claims.

(6)  We account for our interest in Kronos  Worldwide by the equity method as of
     July 1, 2004.

     Preapproval  Policies and  Procedures.  For the purpose of maintaining  the
independence of our independent  registered  public  accounting  firm, our audit
committee has adopted  policies and procedures for the  preapproval of audit and
permitted  non-audit services the firm provides to us or any of our subsidiaries
other than our publicly held subsidiaries and their respective subsidiaries.  We
may not  engage  the firm to render  any audit or  permitted  non-audit  service
unless the service is approved in advance by our audit committee pursuant to the
committee's  amended and restated  preapproval  policies and procedures that the
committee approved on February 22, 2005. Pursuant to the policy:

     o    the committee must specifically  preapprove,  among other things,  the
          engagement of our independent  registered  public  accounting firm for
          audits and  quarterly  reviews of our financial  statements,  services
          associated with certain  regulatory  filings,  including the filing of
          registration  statements  with the SEC, and services  associated  with
          potential business acquisitions and dispositions involving us; and

     o    for  certain  categories  of  permitted   non-audit  services  of  our
          independent  registered  public  accounting  firm,  the  committee may
          preapprove  limits on the aggregate  fees in any calendar year without
          specific approval of the service.

These permitted non-audit services include:

     o    audit services,  such as certain  consultations  regarding  accounting
          treatments or interpretations  and assistance in responding to certain
          SEC comment letters;

     o    audit-related  services, such as certain other consultations regarding
          accounting  treatments  or  interpretations,   employee  benefit  plan
          audits, due diligence and control reviews;

     o    tax services, such as tax compliance and consulting, transfer pricing,
          customs and duties and expatriate tax services; and

     o    other permitted non-audit services,  such as assistance with corporate
          governance  matters and filing documents in foreign  jurisdictions not
          involving the practice of law.

     Pursuant to the  policy,  our audit  committee  has  delegated  preapproval
authority to the  chairman of the  committee or his designee to approve any fees
in excess of the annual  preapproved  limits for these  categories  of permitted
non-audit  services  provided by our independent  registered  public  accounting
firm.  The  chairman  must report any action  taken  pursuant to this  delegated
authority at the next meeting of the committee.

     For 2005, our audit committee preapproved all PwC's services provided to us
or any of our subsidiaries,  other than our publicly held subsidiaries and their
subsidiaries,  in compliance with the amended and restated  preapproval policies
and  procedures  without  the use of the  SEC's  de  minimis  exception  to such
preapproval requirement.

                                  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.








   SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS FOR THE 2007 ANNUAL MEETING

     Shareholders  may submit  proposals on matters  appropriate for shareholder
action at our annual shareholder meetings,  consistent with rules adopted by the
SEC. We must  receive  such  proposals  not later than  December  18, 2006 to be
considered for inclusion in the proxy  statement and form of proxy card relating
to the annual meeting of shareholders in 2007.

     The board of directors will consider the director  nominee  recommendations
of  our   shareholders.   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,  our management has recommended  director nominees to the board of
directors.  Because  under the NYSE  listing  standards we may be deemed to be a
controlled company,  the board of directors believes that additional policies or
procedures with regard to the consideration of director  candidates  recommended
by its shareholders are not appropriate.

     Proposals and nominations should be addressed to: Corporate  Secretary,  NL
Industries,  Inc., Three Lincoln Centre,  5430 LBJ Freeway,  Suite 1700, Dallas,
Texas 75240-2697.

                   COMMUNICATIONS WITH THE BOARD OF DIRECTORS

     Shareholders and other interested  parties who wish to communicate with the
board  of  directors  or its  non-management  directors  may do so  through  the
following  procedures.  Such communications not involving complaints or concerns
regarding accounting,  internal accounting controls and auditing matters related
to us may be sent to the attention of our corporate  secretary at NL Industries,
Inc.,  Three  Lincoln  Centre,  5430 LBJ  Freeway,  Suite  1700,  Dallas,  Texas
75240-2697.  Provided  that any such  communication  relates to our  business or
affairs and is within the function of our board of directors or its  committees,
and  does  not  relate  to   insignificant  or   inappropriate   matters,   such
communications,  or summaries of such  communications,  will be forwarded to the
chairman of our audit  committee,  who also serves as the presiding  director of
our non-management and independent director meetings.

     Complaints or concerns regarding  accounting,  internal accounting controls
and  auditing  matters,  which  may be made  anonymously,  should be sent to the
attention of our general counsel with a copy to our chief  financial  officer at
the same address as our corporate  secretary.  These complaints or concerns will
be  forwarded  to the  chairman  of our  audit  committee.  We will  keep  these
complaints  or concerns  confidential  and  anonymous,  to the extent  feasible,
subject to applicable law. Information  contained in such a complaint or concern
may be  summarized,  abstracted  and  aggregated  for  purposes of analysis  and
investigation.

                         2005 ANNUAL REPORT ON FORM 10-K

     A copy of our Annual Report on Form 10-K for the fiscal year ended December
31,  2005 is included as part of the annual  report  mailed to our  shareholders
with  this  proxy  statement  and  may  also  be  accessed  on  our  website  at
www.nl-ind.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  shareholders  reside if they appear to be members of the same
family.  Each  shareholder  continues  to receive a separate  proxy  card.  This
procedure,  referred  to  as  householding,  reduces  the  volume  of  duplicate
information  shareholders  receive and reduces mailing and printing expenses.  A
number of  brokerage  firms have  instituted  householding.  Certain  beneficial
shareholders 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
shareholder  at that  address  gave  contrary  instructions.  If, at any time, a
shareholder 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  shareholder  currently  receives  multiple copies of the
proxy  statement  and related  materials at his or her address and would like to
request householding of our communications, the shareholder should notify his or
her broker.  Additionally,  we will promptly deliver a separate copy of our 2005
annual report or this proxy  statement to any shareholder at a shared address to
which a single copy of such  documents was  delivered,  upon the written or oral
request of the shareholder.

     To obtain copies of our 2005 annual report or this proxy statement  without
charge, please mail your request to the attention of Robert D. Graham, corporate
secretary, at NL Industries, Inc., Three Lincoln Centre, 5430 LBJ Freeway, Suite
1700, Dallas, Texas 75240-2697, or call him at 972.233.1700.

                             AUDIT COMMITTEE CHARTER

                       AMENDED AND RESTATED JUNE 30, 2005

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

                                   ARTICLE I.
                                     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:

     o    the integrity of the corporation's  financial  statements and internal
          control over financial reporting;

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

     o    the independent auditor's qualifications and independence; and

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

                                   ARTICLE II.
    RELATIONSHIP WITH THE CORPORATION, MANAGEMENT AND THE INDEPENDENT AUDITOR

     Management  is  responsible  for  preparing  the  corporation's   financial
statements  and  maintaining  internal  control over  financial  reporting.  The
corporation's  independent auditor is responsible for auditing the corporation's
financial  statements  and  internal  control  over  financial  reporting.   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 or internal control over financial reporting.
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,  employees,  agents, counsel, experts, auditors or 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, and nothing in this charter will, or will be
deemed to,  decrease or modify in any manner  adverse to any member of the audit
committee such member's right to rely on such information,  opinions, reports or
statements.

     Nothing in this charter will, or will be deemed to, adversely affect in any
manner the rights of members of the committee to indemnification and advancement
of expenses under the  corporation's  certificate of incorporation or bylaws, or
under any contract,  agreement,  arrangement or  understanding  that may benefit
such member. In addition,  notwithstanding  any other provision of this charter,
no provision of this charter will,  except to the extent  required by applicable
law,  rule or  regulation,  be  construed  to  create  any  duty,  liability  or
obligation on the part of the committee or any of its members.

                                  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.

     The audit committee may invite to its meetings any director,  any member of
management  of the  corporation  and any other persons it deems  appropriate  in
order to carry out its  responsibilities.  The audit  committee may also exclude
from its  meetings  any persons it deems  appropriate  in order to carry out its
responsibilities.

                                   ARTICLE V.
                                RESPONSIBILITIES

     The audit  committee  may from time to time  perform  any other  activities
consistent  with  this  charter,  the  corporation's   charter  and  bylaws  and
