                                 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 1998 Annual
Meeting of Shareholders to be held at 10:00 a.m.  (C.D.T.) on Wednesday,  May 6,
1998, 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 6, 1998.


                            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  1999
Annual Meeting of Shareholders  and until their  successors are duly elected and
qualified,  (ii) a proposal  to adopt the NL  Industries,  Inc.  1998  Long-Term
Incentive Plan (the "Plan"),  and (iii) such other business as may properly come
before the Annual  Meeting.  The  Company is not aware of any  business  to come
before the Annual  Meeting other than the election of directors and the proposal
to adopt the Plan.


                  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, including the adoption of the Plan, 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  of
Directors.  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, 1998
(the "Record  Date").  As of the Record Date,  there were issued and outstanding
51,290,614 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"),  a
diversified  company  engaged in the  chemicals,  component  products  and waste
management industries,  and Tremont Corporation  ("Tremont"),  a holding company
engaged in the titanium metals and chemicals industries,  held approximately 58%
and 18%,  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.  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 the seven
nominees for  director,  (ii) "FOR" the  adoption of the Plan,  and (iii) 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 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 regular  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.

      First Chicago Trust  Company of New York ("First  Chicago"),  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 First Chicago shall be kept confidential by
First Chicago in accordance with the terms of the Company's By-Laws.


      IT IS THE INTENTION OF THE AGENTS DESIGNATED IN THE ENCLOSED PROXY CARD TO
VOTE "FOR" THE ELECTION OF ALL SEVEN NOMINEES FOR DIRECTOR  IDENTIFIED BELOW AND
"FOR"  ADOPTION OF THE PLAN  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  58%  AND  18%,
RESPECTIVELY,  OF THE OUTSTANDING  COMMON STOCK,  HAVE INFORMED THE COMPANY THAT
THEY  INTEND TO VOTE  THEIR  SHARES IN FAVOR OF THE  NOMINEES  SET FORTH IN THIS
PROXY  STATEMENT  AND IN FAVOR OF  ADOPTION OF THE PLAN.  VALHI'S AND  TREMONT'S
VOTES  TOGETHER,  OR VALHI'S  VOTES  ALONE,  ARE  SUFFICIENT  TO ELECT ALL SEVEN
NOMINEES AND TO APPROVE ADOPTION OF THE PLAN.


                              ELECTION OF DIRECTORS

      The Certificate  provides for a Board of Directors  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
1999  Annual  Meeting of  Shareholders  or until his  successor  shall have been
elected and qualified or until his earlier resignation, removal or death. All of
the nominees are currently  directors of the Company and have agreed to serve if
elected.

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

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 1997.  The  current  members of the
Nominations Committee are Mr. Glenn Simmons,  Chairman,  Admiral Zumwalt and Mr.

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

- --------- (1) All beneficial ownership is sole and direct unless otherwise noted. (2) No percent of class is shown for holdings of less than 1%. (3) Valhi Group, Inc. ("VGI"), National City Lines, Inc. ("National") and Contran are the holders of approximately 74.8%, 9.5% and 7.8%, respectively, of the outstanding common stock, $.01 par value per share, of Valhi, Inc. (the "Valhi Common Stock"). VGI, National, the Harold Simmons Foundation, Inc. (the "Foundation"), Contran and Valhi hold approximately 35.1%, 5.2%, 3.7%, 3.5% and 1.5%, respectively, of the outstanding common stock, $1.00 par value per share, of Tremont (the "Tremont Common Stock"). In addition, NL and Valmont each hold 0.5% of Tremont Common Stock. National, NOA, Inc. ("NOA") and Dixie Holding Company ("Dixie Holding") are the holders of approximately 73.3%, 11.4% and 15.3%, respectively, of the outstanding common stock of VGI. Contran and NOA are the holders of approximately 85.7% and 14.3%, respectively, of the outstanding common stock of National. Contran and Southwest Louisiana Land Company, Inc. ("Southwest") are the holders of approximately 49.9% and 50.1%, respectively, of the outstanding common stock of NOA. Dixie Rice Agricultural Corporation, Inc. ("Dixie Rice") is the holder of 100% of the outstanding common stock of Dixie Holding. Contran is the holder of approximately 88.8% and 54.3% of the outstanding common stock of Southwest and Dixie Rice, respectively. Substantially all of Contran's outstanding voting stock is held by trusts established for the benefit of certain of Harold C. Simmons' children and grandchildren (the "Trusts"), of which Harold C. Simmons is the sole trustee. As sole trustee of the Trusts, Harold C. Simmons has the power to vote and direct the disposition of the shares of Contran common stock held by each of the Trusts. Mr. Simmons, however, disclaims beneficial ownership of such Contran shares. The Combined Master Retirement Trust (the "Master Trust") holds approximately 0.1% or less of the outstanding shares of Valhi Common Stock and Tremont Common Stock. The Master Trust was formed to permit the collective investment by trusts that maintain the assets of certain employee benefit plans adopted by Valhi and related companies. Harold C. Simmons is the sole trustee of the Master Trust and the sole member of the trust investment committee for the Master Trust. The trustee and members of the trust investment committee for the Master Trust are selected by Valhi's Board of Directors. Harold C. Simmons and Glenn R. Simmons are members of Valhi's Board of Directors and are participants in one or more of the employee benefit plans which invest through the Master Trust. Each of such persons, however, disclaims beneficial ownership of the shares of Valhi Common Stock and Tremont Common Stock held by the Master Trust, except to the extent of his individual vested beneficial interest in the assets held by the Master Trust. Harold C. Simmons is Chairman of the Board of NL and Chairman of the Board, President and Chief Executive Officer of Contran, Dixie Holding, NOA, National, VGI and Valhi. Mr. Simmons is also Chairman of the Board and Chief Executive Officer of Dixie Rice and Southwest, and a director of Tremont. By virtue of the holding of such offices, the stock ownership and his service as trustee, all as described above, (a) Mr. Simmons may be deemed to control such entities, and (b) Mr. Simmons, and certain of such entities may be deemed to possess indirect beneficial ownership of the Common Stock directly beneficially owned by Valhi and Tremont and the shares of Valhi Common Stock and Tremont Common Stock held by Contran and its subsidiaries. However, Mr. Simmons disclaims beneficial ownership of the shares of Common Stock, Valhi Common Stock and Tremont Common Stock beneficially owned, directly and indirectly, by such entities. The shares of Valhi Common Stock described above as owned by Contran include approximately 0.2% of the outstanding Valhi Common Stock which is directly held by the Contran Deferred Compensation Trust No. 2 (the "CDCT No. 2"). The shares of Tremont Common Stock described above as owned by Contran include approximately 3.5% of the outstanding Tremont Common Stock which is directly held by the CDCT No. 2. Boston Safe Deposit and Trust Company serves as trustee of the CDCT No. 2 (the "Trustee"). Contran established the CDCT No. 2 as an irrevocable "rabbi trust" to assist Contran in meeting certain deferred compensation obligations that it owes to Harold C. Simmons. If the CDCT No. 2 assets are insufficient to satisfy such obligations, Contran must satisfy the balance of such obligations. Under the terms of the CDCT No. 2, Contran (i) retains the sole power to vote the Valhi Common Stock and Tremont Common Stock held by the CDCT No. 2, (ii) retains dispositive power over such shares, and (iii) may be deemed the indirect beneficial owner of such shares. However, Mr. Simmons disclaims such beneficial ownership of the shares beneficially owned by the CDCT No. 2, except to the extent of his interest as a beneficiary of CDCT No. 2. The Foundation directly holds approximately 3.7% of the outstanding Tremont common stock and 0.5% of the outstanding Valhi common stock. The Foundation is a tax-exempt foundation organized for charitable purposes. Harold C. Simmons is the chairman of the board and chief executive officer of the Foundation and may be deemed to control the Foundation. Mr. Simmons, however, disclaims beneficial ownership of any shares held by the Foundation.

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 which 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. 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, 1997. COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS AND OTHER INFORMATION Compensation of Directors During 1997, 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, plus an attendance fee of $750 for each meeting of the Board or a committee at which the director was present. Such directors also received a fee of $750 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 designated beneficiary or estate will be entitled to receive a life insurance benefit equal to the annual retainer then in effect. Directors receiving fees for serving on the Board of Directors in 1997 were Messrs. Peak, G. Simmons, H. Simmons, and Admiral Zumwalt. See "Certain Relationships and Transactions." In 1997, Admiral Zumwalt and Mr. Peak were each granted an option pursuant to the Director Plan (as defined above) to purchase 1,000 shares of Common Stock at an exercise price of $12.00 per share, representing the last reported sales price of Common Stock on the New York Stock Exchange Composite Tape on the date of grant. Options granted under the Director Plan become exercisable one year after the date of grant and expire on the fifth anniversary following the date of grant.

(1) No payouts under any long-term incentive plans (as defined by applicable federal securities regulations) were made during 1997, 1996 or 1995, and no other annual compensation payments were made in 1997, 1996 or 1995. Therefore, columns for such compensation otherwise required by applicable federal securities regulations have been omitted. (2) Amounts paid pursuant to the Variable Compensation Plan. See "Compensation Committee's Report on Executive Compensation" below. (3) During 1997, 1996 and 1995, Mr. Martin also served as an executive officer of Tremont and TIMET.

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." (4) During 1997, 1996, and 1995, Mr. Compofelice also served as an executive officer of Tremont and Valhi. Mr. Compofelice commenced employment as an executive officer of TIMET in 1996. He was compensated directly by NL and TIMET and/or Tremont for services to such companies in 1997, 1996 and 1995. NL was credited by Valhi for the portion of Mr. Compofelice's salary earned for services attributable to Valhi in 1997, 1996 and 1995 against the amount otherwise payable by NL to Valhi pursuant to the intercorporate services agreement between NL and Valhi. See "Certain Relationships and Transactions." Amounts paid in 1997, 1996 and 1995 by NL to Mr. Compofelice that were credited by Valhi are included in the table above. The amounts in the table above exclude certain payments made through the NL payroll system which were funded entirely by an affiliate.

(1) Grants of options to purchase shares of Common Stock under the Incentive Plan vest over five years from February 12, 1997, 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 of $11.875 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; exercise prices of $13.375 and $14.875 are equal to the foregoing mean price on the date of grant plus $1.50 and $3.00, respectively. (3) Pursuant to the rules of the Commission, these amounts reflect the calculations at assumed 5% and 10% 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 $19.34 and $30.80 at the assumed 5% and 10% rates, respectively. Stock Option Exercises and Holdings The following table provides information with respect to the executive officers 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, 1997. Three such executive officers exercised options during 1997 as shown in the table below. No stock appreciation rights have been granted under the Incentive Plan.

Pension Plan The Retirement Plan of NL Industries, Inc. for its U.S. employees (the "Pension Plan") provides lifetime retirement benefits to eligible employees. In February 1996, the Company approved the suspension of all future accruals under the salaried component of the Pension Plan effective as of March 31, 1996 (the "Suspension Date"). Salaried employees who were at least 21 years of age became eligible to participate in the Pension Plan if they completed at least five months of service (as defined in the Pension Plan) in a specified twelve-month period prior to the Suspension Date. Annually, prior to the Suspension Date, the Board established, in its discretion, the amount of an employee's annual pension benefit for the year based primarily on the employee's total eligible earnings for that year and the Company's financial performance in relationship to its annual operating plan for the previous year. To the extent that the minimum, target, or maximum level of operating income performance were achieved, the employee earned an annual benefit equal to 1%, 2% or 3%, respectively, of such employee's total base salary and bonus, up to the limits set forth in the Internal Revenue Code. See "Compensation Committee's Report on Executive Compensation - Variable Compensation Plan" below. Such pension benefits are payable upon retirement and attainment of ages specified in the Pension Plan. The Pension Plan covers each executive officer named in the Summary Compensation Table set forth above. No amounts were paid or distributed to any of the named executive officers in 1997. The estimated accrued annual benefits payable upon retirement at normal retirement age for Dr. Wigdor and Messrs. Martin, Compofelice, Garten and Newkirk are $29,438, $50,239, $9,293, $26,405 and $29,084, respectively. Employment Agreements Mr. Martin has entered into an executive severance agreement with the Company which provides that he may be terminated at any time by action of the Board of Directors. The Company and Mr. Martin have amended the executive severance agreement originally entered into in December 1991 to provide that the following payments shall be made to Mr. Martin in the event Mr. Martin is terminated by the Company without cause (as defined in the agreement) or Mr. Martin terminates his employment with the Company for good reason (as defined in the agreement): (i) two times Mr. Martin's annual base salary plus target bonus (which shall not be less than the amount of his annual salary); (ii) accrued salary and bonus through the date of termination; and certain other benefits. The amended agreement provides that it shall be in effect through December 31, 2000. In connection with the commencement of Mr. Compofelice's employment with the Company in February 1994, the MDC Committee (as defined below) approved the terms of an executive severance agreement with Mr. Compofelice which have since been incorporated into an executive severance agreement which provides that Mr. Compofelice may be terminated at any time by action of the Board of Directors. The executive severance agreement also provides that the following payments shall be made to Mr. Compofelice in the event Mr. Compofelice is terminated by the Company without cause (as defined in the agreement) or Mr. Compofelice terminates his employment with the Company for good reason (as defined in the agreement): (i) the greater of two times Mr. Compofelice's annual base salary plus target bonus (which shall not be less than the amount of his annual salary) or Mr. Compofelice's actual salary and bonus for the two years prior to termination; (ii) accrued salary and bonus through the date of termination; (iii) an amount in cash or Common Stock equal to the fair market value of outstanding stock options granted to Mr. Compofelice in excess of the exercise price and unvested restricted stock grants; (iv) an amount equal to unvested Company contributions together with an amount equal to the Company's matching contributions to Mr. Compofelice's account under the Savings Plan for a period of two years; (v) an amount equal to the vested and unvested portions of Mr. Compofelice's account under the SERP; and (vi) certain other benefits. This agreement is automatically extended for a one-year term commencing each January 1, unless the Company and Mr. Compofelice agree otherwise in writing. Mr. Compofelice left the employment of the Company in February 1998; no amounts were paid or are due under the agreement. Dr. Wigdor and the Company entered into an executive severance agreement in March 1995 on terms substantially similar to those in the agreement between the Company and Mr. Compofelice described above. 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 such committees. The MDC Committee reviews and recommends executive officer compensation policies and practices. The MDC Committee was responsible for reviewing and approving all compensation actions during 1997, including stock-based compensation, involving the Company's executive officers. However, any action in connection with the Chief Executive Officer's (the "CEO") base salary is reviewed and approved by the Board after recommendation by the MDC Committee. See "Meetings and Committees." The Company's compensation system with respect to its executive officers, including the CEO, consists of three primary components: base salary, annual variable compensation pursuant to the Variable Compensation Plan, and the grant of stock options, restricted stock and/or stock appreciation rights pursuant to the Incentive Plan. 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 such officers to maximize annual operating performance and long-term shareholder value. Base Salaries The MDC Committee reviews any recommendations of the CEO regarding changes in base salaries for executive officers. Such recommendations are made after the CEO's consultation with the Chairman of the Board. Reviews regarding changes in the base salaries of executive officers occur no more frequently than annually. 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 1997 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 market conditions for executives in general with similar skills, background and performance levels, both inside and outside of the chemicals industry (such companies may include companies contained in the peer group index plotted on the Performance Graph following this report), and other companies with similar financial and business characteristics as the Company, or where the executive in question has similar responsibilities. In 1997, the MDC Committee approved a base annual salary increase for Mr. Compofelice from $185,000 to $260,000 and for Mr. Martin from $400,000 to $500,000. In addition, the Committee determined that Ms. Alderton should receive a base salary with respect to 1996 on a full time basis. No action was taken with respect to the base salaries of any of the other executive officers of the Company. 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 certain executive officers). Awards are based primarily on the Company's main business segment achieving annual predetermined operating income goals and secondarily, with respect to certain of the executive officers, on individual performance. 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 segments' 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 variable compensation payments that in 1997 ranged between 14% and 60% of base salary, depending on the executive. If the Target Level is reached, the range of variable compensation payments is higher, and in 1997 ranged between 22% and 100% of base salary, depending on the executive. If the Maximum Level is reached or exceeded, executives are eligible to receive the highest variable compensation payments, and in 1997 the range of payments for which executives were eligible was between 35% and 150% of base salary, depending on the executive. In view of the achievement of operating income during 1996 below the Minimum Level, in 1997 the MDC Committee approved no 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. 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. No such awards were made as to executive officers in 1997. 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. See "Pension Plan" above. Stock-Based Compensation The 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 1997, 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 1997, 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 1997 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. In 1997 the MDC Committee granted options in three exercise price tranches. One-third of such options granted in 1997 are exercisable at the fair market value of the Common Stock on the date of grant. The remaining two-thirds of the options are exercisable at levels that are above the market price on the date of grant. See the Summary Compensation Table above. Although permitted under the Incentive Plan, the MDC Committee in 1997 did not make or recommend any grants of restricted stock, stock appreciation rights or other equity-based awards. To encourage growth in shareholder value, the MDC Committee believes that executives who are in a position to make a substantial contribution to the long-term success of the Company should have a significant stake in its ongoing success. In 1993, the MDC Committee established goals for minimum Common Stock ownership for executive officers to encourage executives to build their Common Stock ownership. Executives are encouraged to achieve these ownership goals over the coming year. The MDC Committee intends to take into consideration in making future grants of stock options after 1998, among other things, whether or not an executive has achieved his or her ownership goals. The table below shows the goals for the Company's executive officers at year-end 1997 for minimum Common Stock ownership and year-end market value of the actual share ownership (excluding unexercised options) as a multiple of 1997 base salary. Year-End Market Value of Share Ownership as a Multiple of Base Salary Actual Goal President and Chief Executive Officer 4.3X 4X Executive Vice President 2.2X 3X Vice Presidents: Chief Financial Officer 2.6X 3X Controller 3.3X 2X General Counsel 2.5X 2X Treasurer 3.2X 2X Tax Code Limitation on Executive Compensation Deductions In 1993, Congress amended the Internal Revenue Code to impose 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 transition rules and exceptions for compensation received pursuant to non-discretionary performance-based plans approved by such company's shareholders. In 1996, the Board and the Company's shareholders approved amendments to the Company's Variable Compensation Plan and Incentive Plan which permit compensation paid or awards or grants made to executives pursuant to such plans to continue to qualify for deductibility by the Company. The foregoing report on executive compensation has been furnished by the Company's MDC Committee of the Board of Directors. Mr. Kenneth R. Peak (Chairman) Admiral Elmo R.

PROPOSAL TO APPROVE ADOPTION OF THE NL INDUSTRIES, INC. 1998 LONG-TERM INCENTIVE PLAN The Board of Directors seeks the approval by the Company's shareholders of the NL Industries, Inc. 1998 Long-Term Incentive Plan (the "Plan"). The Board of Directors adopted the Plan in March 1998, subject to shareholder approval. The text of the Plan is attached as Appendix A. The description of the Plan in this proxy statement is qualified in its entirety by reference to the complete text of the Plan in Appendix A. Description of the Plan General Purpose. The purpose of the Plan is to advance the interests of NL and its shareholders by providing incentives to certain eligible persons who contribute significantly to the strategic and long-term performance objectives and growth of NL. Types of Awards. The Plan provides for awards or grants of stock options, stock appreciation rights ("SARs"), restricted stock, performance grants and other awards deemed by the MDC Committee to be consistent with the purposes of the Plan (collectively, "Awards"). Eligible Persons. Key individuals employed by, or performing services for, NL are eligible to receive Awards. A person who is eligible to receive an Award may be a nonemployee director or some other person who is not employed by NL. Administration. Generally, a committee of the Board of Directors consisting of two or more individuals administers the Plan (the "Committee"). The Plan provides that the MDC Committee is the initial committee to administer the Plan. In certain other instances, the Board of Directors or other persons may administer the Plan. The Plan requires that the membership of the Committee consist of "nonemployee directors" as defined in Rule 16b-3 promulgated by the Commission under the Exchange Act and "outside directors" as defined under regulations promulgated by the Department of Treasury under Section 162(m) of the Internal Revenue Code. Eligible persons entitled to receive Awards include members of the Committee. The Committee determines the eligible persons to whom it grants Awards and the type, size and terms of such Awards. The Committee may also amend the terms of any Award if the Committee could grant such amended Award under the terms of the Plan at the time of such amendment. In addition, the Committee can construe and interpret the Plan and any Award and make all other determinations deemed necessary or advisable for the administration of the Plan. Number of Shares Subject to the Plan. The Plan reserves a maximum of 5,000,000 shares of NL Common Stock for Awards, subject to certain adjustments. NL Common Stock issued under the Plan may be either newly issued shares, treasury shares, reacquired shares or any combination of the three. If any shares of NL Common Stock issued as restricted stock under the Plan are reacquired by the Company pursuant to such rights, or if any Award is canceled, terminates or expires unexercised, the NL Common Stock that would otherwise have been issuable pursuant to such Award will be available for issuance under new Awards. Annual Limit on Awards to an Individual. Subject to certain adjustments, no Eligible Person may receive Awards for more than one million shares of NL Common Stock in any one fiscal year. Limitations on Transfers of Awards. Generally, an Award is nontransferable except by approval of the Committee or by will or the laws of descent and distribution. Incentive Stock Options, however, are transferable only by will or the laws of descent and distribution. Description of Awards under the Plan Stock Options. An Award of a Stock Option (a "Stock Option") is the right to purchase a specified number of shares of NL Common Stock at a specified exercise price, both of which the Committee determines. The Committee can choose whether on not the grant of a Stock Option requires the recipient to pay a purchase price at the time of grant. The Committee also determines when and how a Stock Option becomes exercisable. The term of a Stock Option, however, cannot exceed ten years. A Stock Option may be either a Nonqualified or an Incentive Stock Option. The Committee may grant Nonqualified Stock Options to any eligible person under the Plan. The exercise price for Nonqualified Stock Options may be at any price the Committee determines. The Committee may only grant Incentive Stock Options to employees of NL. The exercise price of an Incentive Stock Option may not be less than the fair market value of the underlying shares of NL Common Stock on the date of grant. The maximum aggregate fair market value of NL Common Stock (determined as of the respective dates of grant) with respect to which Incentive Stock Options are first exercisable by any one employee of NL in any calendar year cannot exceed $100,000. If the Committee grants an Incentive Stock Option to an employee who owns more than 10% of the voting power of all classes of the stock of NL or any parent or subsidiary of NL, the option cannot have an exercise price lower than 110% of fair market value on the date of the grant or a term longer than five years. In addition, the recipient of an Incentive Stock Option cannot exercise the option beyond the time the Code allows for the favorable tax treatment of Incentive Stock Options. Payment of the exercise price of a Stock Option must be made in such form as the Committee determines in its discretion. If the Committee allows payment to be made with shares of NL Common Stock, such shares are valued at their fair market value on the day of exercise and shall have been held by the option holder for a period of at least six months. The Committee may grant Stock Options in conjunction with any other Award, except that Incentive Stock Options cannot have an associated Award that is a Nonqualified Stock Option. When the Committee awards a Stock Option in conjunction with an associated Award, the number of NL Common Shares subject to the Stock Option may be reduced on an appropriate basis to the extent that the associated Award is exercised, paid to or otherwise received by the recipient, as determined by the Committee. Stock Appreciation Rights. SARs are rights to receive (without payment to the Company) cash, NL Common Stock, other property or any combination of the three based on the increase in the value of the NL Common Stock specified in the SAR. A SAR that is related to another Award is exercisable only to the extent that the other Award is exercisable and then only during such period or periods as the Committee determines. In addition, a SAR that is associated with a Stock Option is exercisable only when the fair market value of a share of NL Common Stock exceeds the exercise price per share of the associated Stock Option. If a SAR's associated Award is an Incentive Stock Option, the exercise of the SAR is limited to those instances where its exercise would not disqualify the associated Stock Option's status as an Incentive Stock Option under the Code. When the Committee awards a SAR in conjunction with an associated Award, the number of NL Common Shares subject to the SAR may be reduced on an appropriate basis to the extent that the associated Award is exercised, paid to or otherwise received by the recipient, as determined by the Committee. Upon the exercise of a SAR, the holder receives, at the election of the Committee, cash, shares of NL Common Stock, other consideration or any combination of the three equal in value to (or in the discretion of the Committee, less than) the excess of the fair market value of the shares of NL Common Stock subject to such exercise over the exercise price for such shares as specified in the SAR. Restricted Stock. An Award of restricted stock is an award of a number of shares of NL Common Stock that are subject to certain restrictions (e.g., such stock shall be issued but not delivered to the recipient and, generally, shall be forfeited if the recipient's employment or performance of services for NL terminates). Such restrictions exist for a certain restricted period and in accordance with such terms as the Committee specifies. Prior to the expiration of the restricted period and the satisfaction of any applicable terms, a recipient who has received an Award of restricted stock has the rights of ownership of the shares of NL Common Stock subject to such award, including the right to vote and to receive dividends. Performance Grants. At the time an Award of a performance grant is made, the Committee establishes performance objectives during a specified award period. The final value, if any, of a performance grant is determined by the degree to which the performance objectives have been achieved during the award period, subject to adjustments that the Committee may approve based on relevant factors. Performance objectives may be based on the performance of the recipient, NL, one or more of its subsidiaries or one or more of their divisions or units, or any combination of thereof, as the Committee determines. The Committee may, in its discretion, make adjustments in the computation of any performance measure. The maximum value of an Award of a performance grant as established by the Committee may be a fixed amount, an amount that varies from time to time based on the value of the NL Common Stock, or an amount that is determinable from other criteria the Committee specifies. Performance grants may have different classes or series, having different names, terms and conditions. The Committee may grant Awards of performance grants in conjunction with other Awards. If awarded in conjunction with an associated Award, the number of performance grants may be reduced on an appropriate basis to the extent that the associated Award is exercised by, paid to, or otherwise received by, the recipient, as determined by the Committee. The Committee will generally determine the value of an Award of a performance grant as promptly as practicable after the end of the award period or upon the earlier termination of the recipient's employment or performance of services. The Committee may, however, determine the value of the performance grant and pay it out at any time during the award period. If the performance grant does not have an associated Award, the holder of the performance grant will be paid the final value. If the performance grant has value and has an associated Award, however, the Committee will determine whether to cancel the performance grant and permit the recipient to retain the associated Award, to cancel the associated Award and pay out the value of the performance grant or to pay out the value of only a portion of the performance grant and to cancel the associated Award as to an appropriate portion thereof. Payment. Payment of an Award such as a performance grant may be made in cash, shares of NL Common Stock or other consideration (for example, other NL securities or property) or a combination of the three, and in accordance with terms the Committee sets. The Committee may also permit any payments under an Award to be deferred until a later date upon such terms as the Committee provides. Additional Information Adjustments in Shares of NL Common Stock. Under the Plan, if any change in the outstanding shares of NL Common Stock occurs by reason of an extraordinary or unusual event (e.g. stock split, stock dividend, recapitalization or merger), the Committee may direct appropriate changes in the terms of any Award or the number of shares of NL Common Stock available for Awards. Such changes may include the number or kind of securities that may be subject to, the exercise price under, any measure of performance for, or the number or value of, an Award. Amendments to Awards. The Committee may amend or modify any outstanding Award in any manner (including, but not limited to, acceleration of the date of exercise of or payments under any Award) if the Committee could grant such amended or modified Award under the terms of the Plan at the time of such amendment or modification. Only in certain circumstances, however, may the Committee amend or modify an outstanding Award in a material manner that adversely affects the holder of the affected Award without the holder's written consent. Substitution of Awards. The Committee may permit holders of Awards to surrender outstanding Awards in order to exercise or realize the rights under other Awards. In addition, the Committee may allow or require holders of Awards to exchange such outstanding Awards for the grant of new Awards. Significant Corporate Events. In the event of the proposed dissolution or liquidation of NL, all outstanding Awards terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Committee. In the event of a proposed sale of all or substantially all of the assets of NL or the merger of NL with or into another corporation, all restrictions on any outstanding Awards lapse and recipients of Awards become entitled to the full benefit of their Awards immediately prior to the closing date of such sale or merger, unless otherwise provided by the Committee. Rights to Continue as Employee or Service Provider. Neither the Plan nor any Award confers on any individual any right to continue in the employ of, or provide services to, NL. Effectiveness of Rights as Shareholders. A recipient of an Award has no rights as a shareholder with respect to the shares of NL Common Stock issuable pursuant to the Award until the date of issuance of the stock certificate for such shares. Financing. If the Committee deems it advisable, NL may assist recipients of Awards with financing from NL or a third party so as to permit the payment of taxes with respect to an Award or to enable the recipient to acquire, exercise or realize the rights of an Award. Such assistance may take any form as the Committee considers appropriate. Deferrals. The Committee may grant an Award in conjunction with the deferral of a recipient's compensation. The Committee may provide that any such deferred compensation be forfeited to the Company under certain circumstances, subject to an increase or decrease in value based upon specified performance measures or credited with income equivalents until the date or dates of payment of the Award. Alternative Payments for Tax Withholding. The Committee may permit a recipient of an Award to elect to pay taxes required to be withheld with respect to an Award in any appropriate manner (including, without limitation, by the surrender to the Company of shares of NL Common Stock owned by such person or that would otherwise be distributed, or have been distributed, as the case may be, pursuant to such Award). Termination. The Plan terminates on the earlier of the tenth anniversary of the date the Plan is approved by the Company's shareholders or such time as the Board of Directors adopts a resolution terminating the Plan. The Board of Directors may extended the Plan for up to an additional five years for the grant of Awards other than Incentive Stock Options. Amendments to the Plan. The Board of Directors may amend the Plan at any time. Except in certain circumstances, no amendment shall adversely affect in a material manner any right of any recipient of an Award without such recipient's written consent. Registration of NL Common Stock under the Plan. The Company intends to register the issuance of the shares of NL Common Stock under the Plan with the Commission. Federal Income Tax Consequences The following is a summary of the principal current federal income tax consequences of transactions under the Plan. It does not describe all federal tax consequences under the Plan, nor does it describe state, local or foreign tax consequences. Incentive Stock Options. No taxable income is realized by the recipient upon the grant or exercise of an Incentive Stock Option. However, the exercise of an Incentive Stock Option may result in alternative minimum tax liability for the recipient. If no disposition of shares issued to a recipient pursuant to the exercise of an Incentive Stock Option is made by the recipient within two years from the date of grant or within one year after the transfer of such shares to the recipient, then upon sale of such shares, any amount realized in excess of the exercise price will be taxed to the recipient as a short-term or long-term capital gain or loss, depending on how long the shares have been held, and no deduction will be allowed to the Company for federal income tax purposes. If the shares of NL Common Stock acquired upon the exercise of an Incentive Stock Option are disposed of prior to the expiration of the two-year and one-year holding periods described above, generally the recipient will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the shares at exercise (or, if less, the amount realized on an arms'-length sale of such shares) over the exercise price, and the Company will be entitled to deduct such amount. Any further gain realized will be taxed as short-term or long-term capital gain and will not result in any deduction by the Company. Special rules may apply where all or a portion of the exercise price of the Incentive Stock Option is paid by tendering shares of NL Common Stock. If an Incentive Stock Option is exercised at a time when it no longer qualifies for the tax treatment described above, the option is treated as a Nonqualified Stock Option. Generally, an Incentive Stock Option will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (one year following termination of employment by reason of permanent and total disability), except in certain cases where the Incentive Stock Option is exercised after the death of a recipient. Nonqualified Stock Options. With respect to Nonqualified Stock Options granted under the Plan, no income is realized by the recipient at the time the options are granted. Generally, at exercise, ordinary income is realized by the recipient in an amount equal to the difference between the exercise price and the fair market value of the shares on the date of exercise, and the Company receives a tax deduction for the same amount, and at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss, depending on how long the shares have been held. SARs. The grant of a SAR does not result in income for the grantee or in a deduction for the Company. Upon the exercise of a SAR, the grantee generally recognizes ordinary income and the Company is entitled to a deduction equal to the positive difference between the fair market values of the shares subject to the SAR on the date of grant and the date of exercise. Restricted Stock. A recipient of restricted stock generally will be subject to tax at ordinary income rates on the fair market value of the stock at the time the stock is either transferable or is no longer subject to forfeiture, less any amount paid for such stock. The Company is entitled to a corresponding tax deduction for the amount of ordinary income recognized by the recipient. However, a recipient who so elects under Section 83(b) of the Code within 30 days of the date of issuance of the restricted stock will realize ordinary income on the date of issuance equal to the fair market value of the shares of restricted stock at that time (measured as if the shares were unrestricted and could be sold immediately), less any amount paid for such stock. If the shares subject to such election are forfeited, the recipient will not be entitled to any deduction, refund or loss for tax purposes with respect to the ordinary income previously recognized. Upon the sale of the shares after the forfeiture period has expired, the appreciation or depreciation since the shares became transferable or free from risk of forfeiture (or, if a Section 83(b) election was made, since the shares were issued, taking into account the ordinary income previously recognized) will be treated as long-term or short-term capital gain or loss. The holding period to determine whether the recipient has long-term or short-term capital gain or loss begins when the restriction period expires (or upon the earlier issuance of the shares, if the recipient elected immediate recognition of income under Section 83(b)). Performance Awards. The recipient of a performance award will generally be subject to tax at ordinary income rates on any cash received and the fair market value of any NL Common Stock issued under the award, and the Company will generally be entitled to a deduction equal to the amount of ordinary income realized by the recipient. Any cash received under a performance award will be included in income at the time of receipt. The fair market value of any NL Common Stock received will also generally be included in income (and a corresponding deduction will generally be available to the Company) at the time of receipt. The capital gain or loss holding period for any NL Common Stock distributed under a performance award will begin when the recipient recognizes ordinary income with respect to that distribution. Plan Benefits Since the Committee grants Awards in its discretion, the benefits that recipients of Awards shall receive from the Plan are presently indeterminable. THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ADOPTION OF THE PLAN. 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, 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 of Valhi and Contran. Each of the foregoing persons and Mr. Martin and Ms. Alderton are directors of Tremont. Mr. Martin, the Company's President and Chief Executive Officer, and Mr. Compofelice, the Company's former Vice President and Chief Financial Officer, served as executive officers of Tremont and TIMET and as directors of Tremont (in the case of Mr. Martin) and TIMET during 1997. In addition, Mr. Compofelice has served as an executive officer of Valhi since 1994 and as assistant treasurer of NL since February 1998, Mr. Garten has served since 1990 as assistant secretary of Tremont, and Mr. Hardy has served as assistant treasurer of Tremont and TIMET since 1997. Mr. Martin expects to continue to serve in 1998 as an executive officer of TIMET and Tremont and Mr. Compofelice expects to continue to serve in 1998 as an executive officer of Valhi. 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. Compofelice devoted approximately forty percent of his working time to NL and the remainder of his working time to Valhi, TIMET and Tremont. 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 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 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. The services 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 Contran approximately $500,000 in 1997 for services pursuant to the Contran ISA and expects to pay approximately the same amount in 1998 for such services. The Contran ISA is subject to termination or renewal by mutual agreement 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. See "Compensation of Directors and Executive Officers and Other Information" above. The Company and Valhi are parties to an intercorporate services agreement (the "Valhi ISA") whereby Valhi renders certain management, financial and administrative services to the Company and the Company made the services of Joseph S. Compofelice and the Company's internal audit personnel available to Valhi. In addition in 1997, NL provided to Valhi certain insurance and risk management services. Mr. Compofelice serves as an executive officer of Valhi. The Company received total net fees of approximately $138,000 from Valhi for services provided during 1997 after receiving credit for certain insurance and risk management services provided to Valhi in 1996. NL expects to receive a lower net amount for services in 1998. The Valhi ISA is subject to termination or renewal by mutual agreement and may be terminated by either party pursuant to a written notice delivered 30 days prior to a quarter-end. The Company and Tremont are parties to an intercorporate services agreement (the "Tremont ISA") whereby the Company makes available to Tremont certain services with respect to Tremont's insurance, risk management, real property, internal audit and executive secretarial needs. Tremont paid fees of approximately $94,000 to the Company for services pursuant to the Tremont ISA during 1997. In addition, in 1996 the Company provided to Tremont certain tax services totaling approximately $100,000 for which the Company was reimbursed in 1997. The Tremont ISA is subject to termination or renewal by mutual agreement for succeeding one-year terms and may be terminated at anytime by either party pursuant to 90 day prior written notice to the other party. NL expects to receive approximately $105,000 for services to be provided to Tremont in 1998. The Company and TIMET are parties to an intercorporate services agreement (the "TIMET ISA") whereby the Company makes available to TIMET certain services with respect to TIMET's tax, insurance, risk management, real property, internal audit and executive secretarial needs. TIMET paid fees of approximately $519,000 for services pursuant to the TIMET ISA during 1997. The TIMET ISA is subject to termination or renewal by mutual agreement and may be terminated by either party pursuant to a written notice delivered 30 days prior to a quarter-end. NL expects to receive approximately $430,000 for services to be provided to TIMET in 1998. Tremont Registration Rights Agreement. In connection with the December 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. Unless all registration rights are exercised earlier, such agreement expires in December 2001. Valhi Stock Options. At December 31, 1997 Mr. Compofelice and Mr. Hardy held options to purchase 50,000 and 15,000 shares, respectively, of Valhi Common Stock under the terms of Valhi's stock option plan at exercise prices of $7.04 and $14.66 per share. With respect to Mr. Hardy, the Company has agreed to pay Valhi the aggregate difference between the option price and the market value of Valhi's Common Stock on the exercise date if such options are exercised. With respect to transactions during 1997, the Company paid Valhi $106,950 pursuant to such agreement. Insurance Sharing Agreement. An indirect insurance subsidiary 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 the Tremont insurance subsidiary 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 the Tremont insurance subsidiary with respect to certain loss payments and reserves established by such Tremont subsidiary that (a) arise out of claims against the Company and its subsidiaries (the "NL Liabilities"), and (b) are subject to payment by such Tremont subsidiary under its reinsurance contracts with the third-party insurance company. Also pursuant to the Insurance Sharing Agreement, the Tremont insurance subsidiary is to credit the Company with respect to certain underwriting profits or recoveries that such Tremont subsidiary receives from independent reinsurers that relate to the NL Liabilities. As of December 31, 1997 the Company had current accounts payable to such Tremont subsidiary of approximately $3.4 million with respect to such Agreement. CERTAIN LITIGATION In September 1996, a purported shareholder derivative suit was filed in the Chancery Division of the New Jersey Superior Court, Bergen County (Seinfeld v. Simmons et al., Civ. Action No. C-336-96) challenging the Company's 1991 purchase of approximately 10.9 million shares of Common Stock from Valhi, Inc. in connection with a "Dutch auction" tender offer to all shareholders. The complaint names as defendants the Company, Valhi, and the seven persons who served on the Company's Board of Directors in 1991. The complaint alleges, among other things, that the Company's purchase of shares in the Dutch auction was an unfair and wasteful expenditure of the Company's funds that constituted a breach of the defendants' fiduciary duties to the Company's shareholders. The complaint seeks, among other things, rescission of the purchase from Valhi pursuant to the Dutch auction and plaintiff has stated that damages sought are $149 million. The Company and the other defendants answered the complaint and denied all allegations of wrongdoing. In February 1998, the Company and Valhi executed and filed with the court a proposed stipulation of settlement of the case. Under the proposed settlement, which is subject to court approval, Valhi agreed to transfer to the Company 750,000 shares of Common Stock, subject to adjustment depending on the average sales price of the shares during a fifteen trading day period ending five trading days prior to the transfer, up to a maximum of 825,000 shares and down to a minimum of 675,000 shares. Valhi has the option, in lieu of transferring the shares, to transfer cash or cash equivalents equal to the product of the number of shares that would otherwise have been transferred to the Company times the average price. If approved by the court, the transfer of shares or cash is expected to occur in the second or third quarter of 1998. Pursuant to the proposed settlement and subject to court approval, the Company will reimburse plaintiffs for attorneys' fees of up to $3 million and related costs. In November 1991, a purported shareholder derivative suit was filed in the Court of Chancery of the State of Delaware, New Castle County (Kahn v. Tremont Corporation, et al., No. 12339), in connection with Tremont's purchase of 7.8 million shares of NL's outstanding Common Stock from Valhi in 1991. The complaint named as defendants Valhi and all the members of the Board of Directors of Tremont, including Messrs. Martin, Glenn Simmons and Harold Simmons and Ms. Alderton, and alleged that Tremont's purchase of the Company shares constituted a waste of Tremont's assets and a breach of fiduciary duties by Tremont's Board. A trial in this matter was held in June 1995. In March 1996, the Court issued its opinion ruling in favor of the defendants, concluding that the purchase of the interest in NL was entirely fair to Tremont. Plaintiff appealed this decision. Upon appeal, the Delaware Supreme Court reversed and remanded the case to the Chancery Court for further consideration of the fairness of the transaction. In March 1998, Tremont and Valhi executed and filed with the court a proposed stipulation of settlement of the case. Under the proposed settlement, which is subject to court approval, Valhi agreed to transfer to Tremont 1.2 million shares of Common Stock, subject to adjustment depending on the average sales price of the shares during a fifteen trading day period ending five trading days prior to the transfer, up to a maximum of 1.4 million shares and down to a minimum of 1 million shares. Valhi has the option, in lieu of transferring the shares, to transfer cash or cash equivalents equal to the product of the number of shares that would otherwise have been transferred to Tremont times the average price. If approved by the court, the transfer of shares or cash is expected to occur in the second or third quarter of 1998. INDEPENDENT ACCOUNTANTS The firm of Coopers & Lybrand L.L.P. served as independent auditors of the Company for the year ended December 31, 1997, and is expected to be considered for appointment to serve for the year ended December 31, 1998. Representatives of Coopers & Lybrand L.L.P. are not expected to attend the Annual Meeting.

The Committee has all the powers vested in it by the terms of this Plan, such powers to include exclusive authority to select the Eligible Persons to be granted Awards under this Plan, to determine the type, size and terms of the Award to be made to each Eligible Person selected, to modify the terms of any Award that has been granted, to determine the time when Awards will be granted, to establish performance objectives, to make any adjustments necessary or desirable as a result of the granting of Awards to Eligible Persons located outside the United States and to prescribe the form of the agreements embodying Awards made under this Plan. The Committee is authorized to interpret this Plan and the Awards granted under this Plan, to establish, amend and rescind any rules and regulations relating to this Plan, and to make any other determinations that it deems necessary or desirable for the administration of this Plan. The Committee may correct any defect or supply any omission or reconcile any inconsistency in this Plan or in any Award in the manner and to the extent the Committee deems necessary or desirable to carry it into effect. Any decision of the Committee in the interpretation and administration of this Plan, as described herein, shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned.

In addition to all other rights of indemnification and reimbursement to which a member of the Committee and an officer of the Company may be entitled, the Company shall indemnify and hold harmless each such member or officer who was or is a party or is threatened to be made a party to any threatened, pending or completed proceeding or suit in connection with the performance of duties under this Plan against expenses (including reasonable attorneys' fees), judgments, fines, liabilities, losses and amounts paid in settlement actually and reasonably incurred by him in connection with such proceeding or suit, except for his own willful misconduct or as expressly provided otherwise by statute.

Section 4. Participation. Consistent with the purposes of this Plan, the Committee shall have exclusive power to select the Eligible Persons who may participate in this Plan and be granted Awards under this Plan. Eligible Persons may be selected individually or by groups or categories, as determined by the Committee in its discretion. Section 5. Awards under this Plan. (a) Types of Awards. Awards under this Plan may include, but need not be limited to, one or more of the following types, either alone or in any combination thereof: (i) Stock Options, (ii) Stock Appreciation Rights, (iii) Restricted Stock, (iv) Performance Grants and (v) any other type of Award deemed by the Committee in its discretion to be consistent with the purposes of this Plan (including, but not limited to, Awards of or options or similar rights granted with respect to unbundled stock units or components thereof, and Awards to be made to Participants who are foreign nationals or are employed or performing services outside the United States). (b) Maximum Number of Shares that May be Issued. There may be issued under this Plan (as Restricted Stock, in payment of Performance Grants, pursuant to the exercise of Stock Options or Stock Appreciation Rights or in payment of or pursuant to the exercise of such other Awards as the Committee, in its discretion, may determine) an aggregate of not more than 5,000,000 Common Shares, subject to adjustment as provided in Section 15. No Eligible Person may receive Awards under this Plan for more than 1,000,000 Common Shares in any one fiscal year of NL, subject to adjustment as provided in Section 15. Common Shares issued pursuant to this Plan may be either authorized but unissued shares, treasury shares, reacquired shares or any combination thereof. If any Common Shares issued as Restricted Stock or otherwise subject to repurchase or forfeiture rights are reacquired by the Company pursuant to such rights or, if any Award is canceled, terminates or expires unexercised, any Common Shares that would otherwise have been issuable pursuant thereto will be available for issuance under new Awards. (c) Rights with Respect to Common Shares and Other Securities. Except as provided in subsection 8(c) with respect to Awards of Restricted Stock and unless otherwise determined by the Committee in its discretion, a Participant to whom an Award is made (and any person succeeding to such a Participant's rights pursuant to this Plan) shall have no rights as a stockholder with respect to any Common Shares or as a holder with respect to other securities, if any, issuable pursuant to any such Award until the date of the issuance of a stock certificate to him for such Common Shares or other instrument of ownership, if any. Except as provided in Section 15, no adjustment shall be made for dividends, distributions or other rights (whether ordinary or extraordinary, and whether in cash, securities, other property or other forms of consideration, or any combination thereof) for which the record date is prior to the date such stock certificate or other instrument of ownership, if any, is issued. In all events, a Participant with whom an Award agreement is made to issue Common Shares in the future, shall have no rights as a stockholder with respect to Common Shares related to such agreement until issuance to him of a stock certificate representing such shares. Section 6. Stock Options. The Committee may sell Purchased Options or grant other Stock Options either alone, or in conjunction with Associated Awards, either at the time of grant or by amendment thereafter; provided that an Incentive Stock Option may be granted only to Eligible Persons who are employees of the Company and have an Associated Award only to the extent that such Associated Award does not disqualify the Incentive Stock Option's status as such under the Code. Each Stock Option granted or sold under this Plan shall be evidenced by an agreement in such form as the Committee shall prescribe from time to time in accordance with this Plan and shall comply with the applicable terms and conditions of this Section and this Plan, and with such other terms and conditions, including, but not limited to, restrictions upon the Stock Option or the Common Shares issuable upon exercise thereof, as the Committee, in its discretion, shall establish. (a) The exercise price of a Stock Option may be less than, equal to, or greater than, the Fair Market Value of the Common Shares subject to such Stock Option at the time the Stock Option is granted, as determined by the Committee; provided, however, that in the case of an Incentive Stock Option granted to an employee of the Company, the exercise price shall not be less than the Fair Market Value of the Common Shares subject to such Stock Option at the time the Stock Option is granted, or if granted to a Ten Percent Employee, such exercise price shall not be less than 110% of such Fair Market Value at the time the Stock Option is granted. In no event, however, will the exercise price per share of a Stock Option be less than the par value per share of a Common Share. (b) The Committee shall determine the number of Common Shares to be subject to each Stock Option. In the case of a Stock Option awarded in conjunction with an Associated Award, the number of Common Shares subject to an outstanding Stock Option may be reduced on an appropriate basis to the extent that the Associated Award has been exercised, paid to or otherwise received by the Participant, as determined by the Committee. (c) Any Stock Option may be exercised during its term only at such time or times and in such installments as the Committee may establish. (d) A Stock Option shall not be exercisable: (i) in the case of any Incentive Stock Option granted to a Ten Percent Employee, after the expiration of five years from the date it is granted, and, in the case of any other Stock Option, after the expiration of ten years from the date it is granted; and (ii) unless payment in full is made for the shares being acquired thereunder at the time of exercise as provided in subsection 6(i). (e) The Committee shall determine in its discretion and specify in each agreement embodying a Stock Option the effect, if any, the termination of the Participant's employment with or performance of services for the Company shall have on the exercisability of the Stock Option; provided, however, that an Incentive Stock Option shall not be exercisable at a time that is beyond the time an Incentive Stock Option may be exercised in order to qualify as such under the Code. (f) In the case of an Incentive Stock Option, the amount of the aggregate Fair Market Value of Common Shares (determined at the time of grant of the Stock Option) with respect to which Incentive Stock Options are exercisable for the first time by an employee of the Company during any calendar year (under all such plans of his employer corporation and its parent and subsidiary corporations) shall not exceed $100,000. (g) It is the intent of NL that Nonqualified Stock Options granted under this Plan not be classified as Incentive Stock Options, that the Incentive Stock Options granted under this Plan be consistent with and contain or be deemed to contain all provisions required under Section 422 and the other appropriate provisions of the Code and any implementing regulations (and any successor provisions thereof), and that any ambiguities in construction shall be interpreted in order to effectuate such intent. (h) A Purchased Option may contain such additional terms not inconsistent with this Plan, including but not limited to the circumstances under which the purchase price of such Purchased Option may be returned to the holder of the Purchased Option, as the Committee may determine in its sole discretion. (i) For purposes of payments made to exercise Stock Options, such payment shall be made in such form (including, but not limited to, cash, Common Shares, the surrender of another outstanding Award under this Plan or any combination thereof) as the Committee may determine in its discretion; provided, however, that for purposes of making such payment in Common Shares, such shares shall be valued at their Fair Market Value on the day of exercise and shall have been held by the Participant for a period of at least six (6) months. Section 7. Stock Appreciation Rights. The Committee may grant Stock Appreciation Rights either alone, or in conjunction with Associated Awards, either at the time of grant or by amendment thereafter. Each Award of Stock Appreciation Rights granted under this Plan shall be evidenced by an agreement in such form as the Committee shall prescribe from time to time in accordance with this Plan and shall comply with the applicable terms and conditions of this Section and this Plan, and with such other terms and conditions, including, but not limited to, restrictions upon the Award of Stock Appreciation Rights or the Common Shares issuable upon exercise thereof, as the Committee, in its discretion, shall establish. (a) The Committee shall determine the number of Common Shares to be subject to each Award of Stock Appreciation Rights. In the case of an Award of Stock Appreciation Rights awarded in conjunction with an Associated Award, the number of Common Shares subject to an outstanding Award of Stock Appreciation Rights may be reduced on an appropriate basis to the extent that the Associated Award has been exercised, paid to or otherwise received by the Participant, as determined by the Committee. (b) The Award of Stock Appreciation Rights shall not be exercisable: (i) unless the Associated Award, if any, is at the time exercisable; (ii) if the Associated Award is a Stock Option and the Fair Market Value per share of the Common Shares on the exercise date does not exceed the exercise price per share of such Stock Option; or (iii) if the Associated Award is an Incentive Stock Option and the exercise of the Award of Stock Appreciation Rights would disqualify the Incentive Stock Option as such under the Code. (c) The Committee shall determine in its discretion and specify in each agreement embodying an Award of Stock Appreciation Rights the effect, if any, the termination of the Participant's employment with or performance of services for the Company shall have on the exercisability of the Award of Stock Appreciation Rights. (d) An Award of Stock Appreciation Rights shall entitle the holder to exercise such Award or to surrender unexercised an Associated Award (or any portion of such Associated Award) to NL and to receive from NL in exchange thereof, without payment to NL, that number of Common Shares having an aggregate value equal to (or, in the discretion of the Committee, less than) the excess of the Fair Market Value of one share, at the time of such exercise, over the exercise price, times the number of shares subject to the Award or the Associated Award, or portion thereof, that is so exercised or surrendered, as the case may be. The Committee shall be entitled in its discretion to elect to settle the obligation arising out of the exercise of a Stock Appreciation Right by the payment of cash or Other NL Securities or property, or other forms of payment or any combination thereof, as determined by the Committee, equal to the aggregate value of the Common Shares it would otherwise be obligated to deliver. Any such election by the Committee shall be made as soon as practicable after the receipt by the Committee of written notice of the exercise of the Stock Appreciation Right. (e) A Stock Appreciation Right may provide that it shall be deemed to have been exercised at the close of business on the business day preceding the expiration date of the Stock Appreciation Right or of the related Stock Option (or other Award), or such other date as specified by the Committee, if at such time such Stock Appreciation Right has a positive value. Such deemed exercise shall be settled or paid in the same manner as a regular exercise thereof as provided in subsection 7(d) hereof. Section 8. Restricted Stock. The Committee may grant Awards of Restricted Stock either alone, or in conjunction with Associated Awards, either at the time of grant or by amendment thereafter. Each Award of Restricted Stock under this Plan shall be evidenced by an agreement in such form as the Committee shall prescribe from time to time in accordance with this Plan and shall comply with the applicable terms and conditions of this Section and this Plan, and with such other terms and conditions as the Committee, in its discretion, shall establish. (a) The Committee shall determine the number of Common Shares to be issued to a Participant pursuant to the Award of Restricted Stock, and the extent, if any, to which they shall be issued in exchange for cash, other consideration, or both. (b) Until the expiration of such period as the Committee shall determine from the date on which the Award is granted and subject to such other terms and conditions as the Committee in its discretion shall establish (the "Restricted Period"), a Participant to whom an Award of Restricted Stock is made shall be issued, but shall not be entitled to the delivery of, a stock certificate representing the Common Shares subject to such Award. (c) Unless otherwise determined by the Committee in its discretion, a Participant to whom an Award of Restricted Stock has been made (and any person succeeding to such a participant's rights pursuant to this Plan) shall have, after issuance of a certificate for the number of Common Shares awarded and prior to the expiration of the Restricted Period, ownership of such Common Shares, including the right to vote such Common Shares and to receive dividends or other distributions made or paid with respect to such Common Shares (provided that such Common Shares, and any new, additional or different shares, or Other NL Securities or property, or other forms of consideration that the Participant may be entitled to receive with respect to such Common Shares as a result of a stock split, stock dividend or any other change in the corporation or capital structure of NL, shall be subject to the restrictions hereinafter described as determined by the Committee in its discretion), subject, however, to the options, restrictions and limitations imposed thereon pursuant to this Plan. (d) The Committee shall determine in its discretion and specify in each agreement embodying an Award of Restricted Stock the effect, if any, the termination of the Participant's employment with or performance of services for the Company during the Restricted Period shall have on such Award of Restricted Stock. Section 9. Performance Grants. The Committee may grant Awards of Performance Grants either alone, or in conjunction with Associated Awards, either at the time of grant or by amendment thereafter. The Award of a Performance Grant to a Participant will entitle him to receive a specified amount determined by the Committee (the "Actual Value"), if the terms and conditions specified in this Plan and in the Award are satisfied. Each Award of a Performance Grant shall be subject to the applicable terms and conditions of this Section and this Plan, and to such other terms and conditions, including but not limited to, restrictions upon any cash, Common Shares, Other NL Securities or property, or other forms of payment, or any combination thereof, issued with respect to the Performance Grant, as the Committee, in its discretion, shall establish, and shall be embodied in an agreement in such form and substance as is determined by the Committee. (a) The Committee shall determine the value or range of values of a Performance Grant to be awarded to each Participant selected for an Award and whether or not such a Performance Grant is granted in conjunction with an Associated Award. As determined by the Committee, the maximum value of each Performance Grant (the "Maximum Value") shall be: (i) an amount fixed by the Committee at the time the Award is made or amended thereafter, (ii) an amount that varies from time to time based in whole or in part on the then current value of the Common Shares, Other NL Securities or property, or other securities or property, or any combination thereof or (iii) an amount that is determinable from criteria specified by the Committee. Performance Grants may be issued in different classes or series having different names, terms and conditions. In the case of a Performance Grant awarded in conjunction with an Associated Award, the Performance Grant may be reduced on an appropriate basis to the extent that the Associated Award has been exercised, paid to or otherwise received by the Participant, as determined by the Committee. (b) The award period ("Award Period") related to any Performance Grant shall be a period determined by the Committee. At the time each Award is made, the Committee shall establish performance objectives to be attained within the Award Period as the means of determining the Actual Value of such a Performance Grant. The performance objectives shall be based on such measure or measures of performance, which may include, but need not be limited to, the performance of the Participant, the Company or one or more of its divisions or units, or any combination of the foregoing, as the Committee shall determine, and may be applied on an absolute basis or be relative to industry or other indices or any combination thereof. The Actual Value of a Performance Grant shall be equal to its Maximum Value only if the performance objectives are attained in full, but the Committee shall specify the manner in which the Actual Value of Performance Grants shall be determined if the performance objectives are met in part. Such performance measures, the Actual Value or the Maximum Value, or any combination thereof, may be adjusted in any manner by the Committee in its discretion at any time and from time to time during or as soon as practicable after the Award Period, if it determines that such performance measures, the Actual Value or the Maximum Value, or any combination thereof, are not appropriate under the circumstances. (c) The Committee shall determine in its discretion and specify in each agreement embodying a Performance Grant the effect, if any, the termination of the Participant's employment with or performance of services for the Company during the Award Period shall have on such Performance Grant. (d) The Committee shall determine whether the conditions of a Performance Grant have been met and, if so, shall ascertain the Actual Value of the Performance Grant. If the Performance Grant has no Actual Value, the Award and such Performance Grant shall be deemed to have been canceled and the Associated Award, if any, may be canceled or permitted to continue in effect in accordance with its terms. If the Performance Grant has any Actual Value and: (i) was not awarded in conjunction with an Associated Award, the Committee shall cause an amount equal to the Actual Value of the Performance Grant earned by the Participant to be paid to him or his permitted assignee or Beneficiary; or (ii) was awarded in conjunction with an Associated Award, the Committee shall determine, in accordance with criteria specified by the Committee (A) to cancel the Performance Grant, in which event no amount with respect thereto shall be paid to the Participant or his permitted assignee or Beneficiary, and the Associated Award may be permitted to continue in effect in accordance with its terms, (B) to pay the Actual Value of the Performance Grant to the Participant or his permitted assignee or Beneficiary as provided below, in which event the Associated Award may be canceled or (C) to pay to the Participant or his Beneficiary, the Actual Value of only a portion of the Performance Grants, in which event all or a portion of the Associated Award may be permitted to continue in effect in accordance with its terms or be canceled, as determined by the Committee. Such determination by the Committee shall be made as promptly as practicable following the end of the Award Period or upon the earlier termination of employment or performance of services, or at such other time or times as the Committee shall determine, and shall be made pursuant to criteria specified by the Committee. (e) Payment of any amount with respect to the Performance Grants that the Committee determines to pay as provided above shall be made by NL as promptly as practicable after the end of the Award Period or at such other time or times as the Committee shall determine, and may be made in cash, Common Shares, Other NL Securities or property, or other forms of payment, or any combination thereof or in such other manner, as determined by the Committee in its discretion. Notwithstanding anything in this Section to the contrary, the Committee may, in its discretion, determine and pay out the Actual Value of the Performance Grants at any time during the Award Period. Section 10. Deferral of Compensation. The Committee shall determine whether or not an Award shall be made in conjunction with the deferral of the Participant's salary, bonus or other compensation, or any combination thereof, and whether or not such deferred amounts may be: (a) forfeited to the Company or to other Participants or any combination thereof, under certain circumstances (which may include, but need not be limited to, certain types of termination of employment or performance of services for the Company); (b) subject to increase or decrease in value based upon the attainment of or failure to attain, respectively, certain performance measures; and/or (c) credited with income equivalents (which may include, but need not be limited to, interest, dividends or other rates of return) until the date or dates of payment of the Award, if any. Section 11. Deferred Payment of Awards. The Committee may specify that the payment of all or any portion of cash, Common Shares, Other NL Securities or property, or any other form of payment, or any combination thereof, under an Award shall be deferred until a later date. Deferrals shall be for such periods or until the occurrence of such events, and upon such terms, as the Committee shall determine in its discretion. Deferred payments of Awards may be made by undertaking to make payment in the future based upon the performance of certain investment equivalents (which may include, but need not be limited to, government securities, Common Shares, other securities, property or consideration, or any combination thereof), together with such additional amounts of income equivalents (which may be compounded and may include, but need not be limited to, interest, dividends or other rates of return or any combination thereof) as may accrue thereon until the date or dates of payment, such investment equivalents and such additional amounts of income equivalents to be determined by the Committee in its discretion. Section 12. Transferability of Awards. Except as may be approved by the Committee, a Participant's rights and interest under this Plan or any Award may not be assigned or transferred, hypothecated or encumbered in whole or in part either directly or by operation of law or otherwise (except in the event of a Participant's death), including, but not by way of limitation, execution, levy, garnishment, attachment, pledge, bankruptcy or in any other manner; provided, however, that any Incentive Stock Option granted pursuant to this Plan shall not be transferable other than by will or the laws of descent and distribution and shall be exercisable during the Participant's lifetime only by him. Section 13. Amendment or Substitution of Awards under this Plan. The terms of any outstanding Award under this Plan may be amended or modified from time to time by the Committee in its discretion in any manner that it deems appropriate (including, but not limited to, acceleration of the date of exercise of any Award and/or payments thereunder) if the Committee could grant such amended or modified Award under the terms of this Plan at the time of such amendment or modification; provided that no such amendment or modification shall adversely affect in a material manner any right of a Participant under the Award without his written consent, unless the Committee determines in its discretion that there have occurred or are about to occur significant changes in the Participant's position, duties or responsibilities, or significant changes in economic, legislative, regulatory, tax, accounting or cost/benefit conditions that are determined by the Committee in its discretion to have or to be expected to have a substantial effect on the performance of the Company, or any affiliate, division or department thereof, on this Plan or on any Award under this Plan. The Committee may, in its discretion, permit holders of Awards under this Plan to surrender outstanding Awards in order to exercise or realize the rights under other Awards, or in exchange for the grant of new Awards, or require holders of Awards to surrender outstanding Awards as a condition precedent to the grant of new Awards under this Plan. Section 14. Termination of a Participant. For all purposes under this Plan, the Committee shall determine whether a Participant has terminated employment with, or the performance of services for, the Company; provided, however, an absence or leave approved by the Company, to the extent permitted by applicable provisions of the Code, shall not be considered an interruption of employment or performance of services for any purpose under this Plan. Section 15. Dilution and Other Adjustments. In the event of any change in the outstanding Common Shares by reason of any stock split, dividend, split-up, split-off, spin-off, recapitalization, merger, consolidation, rights offering, reorganization, combination or exchange of shares, a sale by NL of all or substantially all of its assets, any distribution to shareholders other than a normal cash dividend, or other extraordinary or unusual event, if the Committee shall determine, in its discretion, that such change equitably requires an adjustment in the terms of any Award or the number of Common Shares available for Awards, such adjustment may be made by the Committee and shall be final, conclusive and binding for all purposes of this Plan. Each adjustment made pursuant to this Section shall be made with a view toward preserving the value the affected Award had prior to the event or transaction giving cause to such adjustment. In the event of the proposed dissolution or liquidation of NL, all outstanding Awards shall terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Committee. In the event of a proposed sale of all or substantially all of the assets of NL or the merger of NL with or into another corporation, all restrictions on any outstanding Awards shall lapse and Participants shall be entitled to the full benefit of all such Awards immediately prior to the closing date of such sale or merger, unless otherwise provided by the Committee. Section 16. Designation of Beneficiary by Participant. A Participant may name a beneficiary to receive any payment to which he may be entitled with respect to any Award under this Plan in the event of his death, on a written form to be provided by and filed with the Committee, and in a manner determined by the Committee in its discretion (a "Beneficiary"). The Committee reserves the right to review and approve Beneficiary designations. A Participant may change his Beneficiary from time to time in the same manner, unless such Participant has made an irrevocable designation. Any designation of a Beneficiary under this Plan (to the extent it is valid and enforceable under applicable law) shall be controlling over any other disposition, testamentary or otherwise, as determined by the Committee in its discretion. If no designated Beneficiary survives the Participant and is living on the date on which any amount becomes payable to such a Participant's Beneficiary, such payment will be made to the legal representatives of the Participant's estate, and the term "Beneficiary" as used in this Plan shall be deemed to include such person or persons. If there are any questions as to the legal right of any Beneficiary to receive a distribution under this Plan, the Committee in its discretion may determine that the amount in question be paid to the legal representatives of the estate of the Participant, in which event the Company, the Board, the Committee, the Designated Administrator (if any), and the members thereof, will have no further liability to anyone with respect to such amount. Section 17. Financial Assistance. If the Committee determines that such action is advisable, the Company may assist any Participant in obtaining financing from the Company (or under any program of the Company approved pursuant to applicable law), or from a bank or other third party, on such terms as are determined by the Committee, and in such amount as is required to accomplish the purposes of this Plan, including, but not limited to, to permit the exercise of an Award, the participation therein, and/or the payment of any taxes with respect thereto. Such assistance may take any form that the Committee deems appropriate, including, but not limited to, a direct loan from the Company, a guarantee of the obligation by the Company or the maintenance by the Company of deposits with such bank or third party. Section 18. Miscellaneous Provisions. (a) Any proceeds from Awards shall constitute general funds of NL. (b) No fractional shares may be delivered under an Award, but in lieu thereof a cash or other adjustment shall be made as determined by the Committee in its discretion. (c) No Eligible Person or other person shall have any claim or right to be granted an Award under this Plan. Determinations made by the Committee under this Plan need not be uniform and may be made selectively among Eligible Persons under this Plan, whether or not such Eligible Persons are similarly situated. Neither this Plan nor any action taken hereunder shall be construed as giving any Eligible Person any right to continue to be employed by or perform services for the Company, and the right to terminate the employment of or performance of services by Eligible Persons at any time and for any reason is specifically reserved. (d) No Participant or other person shall have any right with respect to this Plan, the Common Shares reserved for issuance under this Plan or in any Award, contingent or otherwise, until written evidence of the Award shall have been delivered to the recipient and all the terms, conditions and provisions of this Plan and the Award applicable to such recipient (and each person claiming under or through him) have been met. (e) No Common Shares, Other NL Securities or property, other securities or property or other forms of payment shall be issued hereunder with respect to any Award unless counsel for NL shall be satisfied that such issuance will be in compliance with applicable law and any applicable rules of any stock exchange or other market quotation system on which Common Shares are listed. (f) It is the intent of NL that this Plan comply in all respects with Rule 16b-3 and Section 162(m) with respect to Awards granted to executive officers of NL, that any ambiguities or inconsistencies in construction of this Plan be interpreted to give effect to such intention and that if any provision of this Plan is found not to be in compliance with Rule 16b-3 or Section 162(m), such provision shall be deemed null and void with respect to Awards granted to executive officers of NL to the extent required to permit such Awards to comply with Rule 16b-3 and Section 162(m). It is also the intent of NL that this Plan comply in all respects with the provisions of the Code providing favorable treatment to Incentive Stock Options, that any ambiguities or inconsistencies in construction of this Plan be interpreted to give effect to such intention and that if any provision of this Plan is found not to be in compliance with the Incentive Stock Option provisions of the Code, such provision shall be deemed null and void with respect to Incentive Stock Options granted to employees of the Company to the extent required to permit such Incentive Stock Options to receive favorable treatment under the Code. (g) The Company shall have the right to deduct from any payment made under this Plan any federal, state, local or foreign income or other taxes required by law to be withheld with respect to such payment. It shall be a condition to the obligation of NL to issue Common Shares, Other NL Securities or property, other securities or property, or other forms of payment, or any combination thereof, upon exercise, settlement or payment of any Award under this Plan, that the Participant (or any Beneficiary or person entitled to act) pay to NL, upon its demand, such amount as may be required by the Company for the purpose of satisfying any liability to withhold federal, state, local or foreign income or other taxes. If the amount requested is not paid, NL may refuse to issue Common Shares, Other NL Securities or property, other securities or property, or other forms of payment, or any combination thereof. Notwithstanding anything in this Plan to the contrary, the Committee may, in its discretion, permit an Eligible Person (or any Beneficiary or person entitled to act) to elect to pay a portion or all of the amount requested by the Company for such taxes with respect to such Award, at such time and in such manner as the Committee shall deem to be appropriate (including, but not limited to, by authorizing NL to withhold, or agreeing to surrender to NL on or about the date such tax liability is determinable, Common Shares, Other NL Securities or property, other securities or property, or other forms of payment, or any combination thereof, owned by such person or a portion of such forms of payment that would otherwise be distributed, or have been distributed, as the case may be, pursuant to such Award to such person, having a Fair Market Value equal to the amount of such taxes). (h) The expenses of this Plan shall be borne by the Company; provided, however, the Company may recover from a Participant or his Beneficiary, heirs or assigns any and all damages, fees, expenses and costs incurred by the Company arising out of any actions taken by a Participant in breach of this Plan or any agreement evidencing such Participant's Award. (i) This Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Award under this Plan, and rights to the payment of Awards shall be no greater than the rights of the Company's general creditors. (j) By accepting any Award or other benefit under this Plan, each Participant and each person claiming under or through him shall be conclusively deemed to have indicated his acceptance and ratification of, and consent to, any action taken under this Plan by the Company, the Board, the Committee or the Designated Administrator (if applicable). (k) The appropriate officers of the Company shall cause to be filed any reports, returns or other information regarding Awards hereunder of any Common Shares issued pursuant hereto as may be required to be filed by the Company by applicable law and any applicable rules of any stock exchange or other market quotation system on which Common Shares are listed. (l) The validity, construction, interpretation, administration and effect of this Plan, and of its rules and regulations, and rights relating to this Plan and to Awards granted under this Plan, shall be governed by the substantive laws, but not the choice of law rules, of the State of New Jersey. (m) Records of the Company shall be conclusive for all purposes under this Plan or any Award, unless determined by the Committee to be incorrect. (n) If any provision of this Plan or any Award is held to be illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining provisions of this Plan or any Award, but such provision shall be fully severable, and this Plan or Award, as applicable, shall be construed and enforced as if the illegal or invalid provision had never been included in this Plan or Award, as applicable. (o) The terms of this Plan shall govern all Awards under this Plan and in no event shall the Committee have the power to grant any Award under this Plan that is contrary to any of the provisions of this Plan. (p) For purposes of interpretation of this Plan, the masculine pronoun includes the feminine and the singular includes the plural wherever appropriate. Section 19. Plan Amendment or Suspension. This Plan may be amended or suspended in whole or in part at any time from time to time by the Board. No amendment of this Plan shall adversely affect in a material manner any right of any Participant with respect to any Award previously granted without such Participant's written consent, except as permitted under Section 13. Section 20. Plan Termination. This Plan shall terminate upon the earlier of the following dates or events to occur: (a) upon the adoption of a resolution of the Board terminating this Plan; or (b) the tenth anniversary of the Effective Date; provided, however, that the Board may, prior to such date, extend the term of this Plan for an additional period of up to five years for the grant of Awards other than Incentive Stock Options. No termination of this Plan shall materially alter or impair any of the rights or obligations of any person, without his consent, under any Award previously granted under this Plan, except that subsequent to termination of this Plan, the Committee may make amendments or modifications permitted under Section 13. Section 21. Effective Date. This Plan shall be effective, and Awards may be granted under this Plan, on or after the Effective Date.
