The accompanying notice of annual meeting of stockholders sets forth the time, place and purposes of the meeting. The notice, this proxy statement, the accompanying proxy card or voting instruction form and our Annual Report to Stockholders, which includes our Annual Report on Form 10-K for the fiscal year ended December 31, 2005, are first being mailed on or about April 13, 2006 to the holders of our common stock at the close of business on March 28, 2006. Our principal executive offices are located at Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697. Please refer to the Glossary of Terms on page ii for the definitions of capitalized or other terms used in this proxy statement. QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING Q: What is the purpose of the annual meeting? A: At the annual meeting, stockholders will vote on the election of seven directors and any other matter that may properly come before the meeting. Q: How does the board recommend that I vote? A: The board of directors recommends that you vote FOR each of the nominees for director. Q: Who is allowed to vote at the annual meeting? A: The board of directors has set the close of business on March 28, 2006 as the record date for the determination of stockholders entitled to notice of and to vote at the meeting. Only holders of record of our common stock as of the close of business on the record date are entitled to vote at the meeting. On the record date, 48,949,549 shares of our common stock were issued and outstanding. Each share of our common stock is entitled to one vote. Q: How do I vote? A: If your shares are held by a bank, broker or other nominee (i.e., in "street name"), you must follow the instructions from your nominee on how to vote your shares. If you are a stockholder of record, you may: o vote in person at the annual meeting; or o instruct the agents named on the proxy card how to vote your shares by completing, signing and mailing the enclosed proxy card in the envelope provided. If you execute a proxy card but do not indicate how you would like your shares voted for one or more of the nominees, the agents will vote FOR the election of each such nominee for director and, to the extent allowed by applicable law, in the discretion of the agents on any other matter that may properly come before the meeting. Q: Who will count the votes? A: The board of directors has appointed Computershare, our transfer agent and registrar, to receive proxies and ballots, ascertain the number of shares represented, tabulate the vote and serve as inspector of election for the meeting. Q: May I change or revoke my proxy or voting instructions? A: If you are a stockholder of record, you may change or revoke your proxy instructions at any time before the meeting in any of the following ways: o delivering to Computershare a written revocation; o submitting another proxy card bearing a later date; or o voting in person at the meeting. If your shares are held by a bank, broker or other nominee, you must follow the instructions from your nominee on how to change or revoke your voting instructions. Q: What constitutes a quorum? A: A quorum is the presence, in person or by proxy, of the holders of a majority of the outstanding shares of our common stock entitled to vote at the meeting. Under the applicable rules of the NYSE and the SEC, brokers or other nominees holding shares of record on behalf of a client who is the actual beneficial owner of such shares are authorized to vote on certain routine matters without receiving instructions from the beneficial owner of the shares. If such a broker/nominee who is entitled to vote on a routine matter delivers an executed proxy card and does not vote on the matter, such a vote is referred to in this proxy statement as a "broker/nominee non-vote." Shares of common stock that are voted to abstain from any business coming before the meeting and broker/nominee non-votes will be counted as being in attendance at the meeting for purposes of determining whether a quorum is present. Q: What vote is required to elect a director nominee or approve any other matter? A: If a quorum is present, a plurality of the affirmative votes of the holders of our outstanding shares of common stock represented and entitled to be voted at the meeting is necessary to elect each nominee for director. The accompanying proxy card or voting instruction form provides space for you to withhold authority to vote for any of the nominees. Neither shares as to which the authority to vote on the election of directors has been withheld nor broker/nominee non-votes will be counted as affirmative votes to elect director nominees. However, since director nominees need only receive the plurality of the affirmative votes from the holders represented and entitled to vote at the meeting to be elected, a vote withheld from a particular nominee will not affect the election of such nominee. Except as applicable laws may otherwise provide, if a quorum is present, the approval of any other matter that may properly come before the meeting will require the affirmative votes of the holders of a majority of the outstanding shares represented and entitled to vote at the meeting. Shares of our common stock that are voted to abstain from any other business coming before the meeting and broker/nominee non-votes will not be counted as votes for or against any such other matter. Q: Who will pay for the cost of soliciting the proxies? A: We will pay all expenses related to the solicitation, including charges for preparing, printing, assembling and distributing all materials delivered to stockholders. In addition to the solicitation by mail, our directors, officers and regular employees may solicit proxies by telephone or in person for which such persons will receive no additional compensation. We have retained The Altman Group, Inc. to aid in the distribution of this proxy statement and related materials at an estimated cost of $1,200. Upon request, we will reimburse banking institutions, brokerage firms, custodians, trustees, nominees and fiduciaries for their reasonable out-of-pocket expenses incurred in distributing proxy materials and voting instructions to the beneficial owners of our common stock that such entities hold of record. CONTROLLED COMPANY Valhi and NL are the direct holders of 59.0% and 35.8%, respectively, of the outstanding shares of our common stock as of the record date. Together, Valhi and NL own 94.8% of the outstanding shares of our common stock. Valhi is the direct holder of 83.1% of the outstanding shares of NL common stock. Valhi and NL have each indicated their intention to have their shares of our common stock represented at the meeting and voted FOR the election of each of the director nominees to our board of directors. If Valhi alone attends the meeting in person or by proxy and votes as indicated, the meeting will have a quorum present and the stockholders will elect all the nominees to the board of directors. Because of the ownership of our common stock by Valhi and NL, we are considered a controlled company under the listing standards of the NYSE. Pursuant to the listing standards, a controlled company may choose not to have a majority of independent directors, independent compensation, nominating or corporate governance committees or charters for these committees. We have chosen not to have an independent nominating or corporate governance committee. Our board of directors believes that the full board of directors best represents the interests of all of our stockholders and that it is appropriate for all matters that would be considered by a nominating or corporate governance committee to be considered and acted upon by the full board of directors. Applying the NYSE director independence standards, the board of directors has determined that four of our directors are independent and have no material relationship with us other than serving as our directors. While the members of our management development and compensation committee currently satisfy the independence requirements of the NYSE, we have chosen not to satisfy all of the NYSE listing standards for a compensation committee. See "Meetings and Committees of the Board of Directors" for more information on the committees of the board of directors. See also "Stockholder Proposals and Director Nominations for the 2007 Annual Meeting" for a description of our policies and procedures for stockholder nominations of directors. ELECTION OF DIRECTORS Our bylaws provide that the board of directors will consist of one or more members as determined by our board of directors or stockholders. The board of directors has currently set the number of directors at seven. The directors elected at the meeting will hold office until our 2007 Annual Meeting of Stockholders and until their successors are duly elected and qualified or their earlier removal, resignation or death. All of the nominees are currently members of our board of directors whose terms will expire at the meeting. All of the nominees have agreed to serve if elected. If any nominee is not available for election at the meeting, all shares represented by a proxy card will be voted FOR an alternate nominee to be selected by the board of directors, unless the stockholder executing such proxy card withholds authority to vote for such nominee. The board of directors believes that all of its nominees will be available for election at the meeting and will serve if elected.

Pension Plans. The Retirement Program of NL Industries, Inc. for its U.S. employees provides lifetime retirement benefits to eligible employees. In 1996, NL approved the suspension of all future accruals under the salaried component of the pension plan. At December 31, 2005, the estimated accrued annual benefit payable under this Pension Plan upon retirement at normal retirement age for Mr. Maas was $26,778. Dr. Fiand is eligible to receive a pension through KII's German operations under the Bayer Pensionskasse and the Supplemental Pension Promise. All of KII's employees in Germany (including wage earners) who have contributed for five years and are less than 55 years of age are covered by the Bayer Pensionskasse. Each employee contributes 2% of eligible earnings excluding bonus, up to the social security contribution ceiling (currently euro 63,000) and the Bayer Pensionskasse provides an annual benefit of 44% of such employee's accumulated contributions (with a minimum benefit of approximately euro 13 per month). The Supplemental Pension Promise also covers all employees of the German operations who have completed ten years of service. Our German operations accrue 11.25% of the participants' eligible annual earnings excluding bonus in excess of the social security contribution ceiling, up to a maximum of euro 111,000. The Supplemental Pension Promise provides an annual retirement benefit of 20% of all accruals made by our German operations. Benefits for both plans are payable upon retirement and the attainment of ages specified in the plans. No amounts were paid or distributed under these plans to Dr. Fiand in 2005. As of December 31, 2005, the estimated accrued annual benefit payable upon normal retirement at normal retirement age for Dr. Fiand was euro 29,190. Chief Operations Management Consultant. Following his resignation as our chief executive officer in 2003, Lawrence A. Wigdor entered into a consultancy arrangement with us pursuant to which Dr. Wigdor provides ongoing management services to our titanium dioxide operations. In 2005, Dr. Wigdor received monthly payments of $84,000 under the arrangement. For 2005, Dr. Wigdor received an annual discretionary bonus of $1.4 million. For the term of the arrangement, Dr. Wigdor will receive annual discretionary bonuses as determined by our chief executive officer. Under the consultancy arrangement, as amended in January 2006, if we terminate the consultancy arrangement prior to December 31, 2008, Dr. Wigdor will receive twelve months compensation and medical and dental coverage through December 31, 2008 and a pro-rata portion of any bonus for the year in which the termination occurs. The arrangement provides Dr. Wigdor various other benefits, including, medical and dental benefits and office and secretarial support at our New Jersey office. During 2005, Dr. Wigdor exercised previously granted stock options for 78,300 shares of NL common stock and realized an aggregate value from the sale of such shares of $870,287. The amount he realized upon the exercise of stock options is based on the difference between the closing price per share of NL common stock on the day of each exercise and the exercise price per share. At December 31, 2005, Dr. Wigdor held exercisable stock options to purchase 3,000 shares of NL common stock and unexercisable stock options to purchase 20,000 shares of NL common stock. Based on the difference between the exercise price of his individual stock options and the $14.09 per share closing sale price of NL common stock on December 31, 2005, the value of his exercisable and unexercisable stock options to purchase NL common stock was $25,395 and $52,100, respectively.

In addition, any person may obtain a copy of these three documents without charge, by sending a written request to the attention of our corporate secretary at Kronos Worldwide, Inc., Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act requires our executive officers, directors and persons who own more than 10% of a registered class of our equity securities to file reports of ownership with the SEC, the NYSE and us. Based solely on the review of the copies of such forms and representations by certain reporting persons, we believe that for 2005 our executive officers, directors and 10% stockholders complied with all applicable filing requirements under section 16(a) except that after its formation in August 2005 as a parent company of Valhi, VHC failed to file timely its Form 3 and three Forms 4 reporting nine purchases of our common stock by Valhi, which transactions were all timely reported on Forms 4 by our other parent companies. EXECUTIVE COMPENSATION REPORT During 2005, our management development and compensation committee administered certain matters regarding the compensation of our executive officers. Kronos Worldwide ISA During 2005, we paid certain fees to Contran for services provided pursuant to an ISA between Contran and us. Such services provided under this ISA included the services of the following executive officers of ours: Name Positions with Kronos Worldwide - ----------------- ---------------------------------------------------- Harold C. Simmons Chairman of the Board and Chief Executive Officer Steven L. Watson Vice Chairman of the Board James W. Brown Vice President and Controller Robert D. Graham Vice President, General Counsel and Secretary Kelly D. Luttmer Vice President and Tax Director John A. St. Wrba Vice President and Treasurer Gregory M. Swalwell Vice President, Finance and Chief Financial Officer Contran annually determines the aggregate fee to charge us based on the following: o an estimate of the amount of time each Contran employee that performs services for us and our subsidiaries will spend on such services over the year; and o Contran's cost related to such employee, which includes the employee's base salary, incentive compensation and an overhead component that takes into account other employment costs, including medical benefits, unemployment and disability insurance and pension costs and other costs of providing an office, equipment and supplies related to the provision of such services. The portion of the annual charge we pay under the ISA between us and Contran for the services of any particular individual is capped at $1.0 million in the aggregate to enhance our ability to deduct such charge for federal income tax purposes. The amount of the fee we paid in 2005 under this ISA for a person who provided services to us or our subsidiaries represents, in management's view, the reasonable equivalent of "compensation" for such services. It is also management's view that the proposed aggregate charge to us under this ISA is fair to us and our stockholders and the cost for the services provided under the ISA would be no less favorable to us than could otherwise be obtained from an unrelated third party for comparable services. See "Certain Relationships and Transactions-Intercorporate Services Agreements" for the aggregate amount we paid to Contran in 2005 under this ISA. For each named executive officer, the portion of the annual charge we paid in 2005 to Contran under this ISA attributable to the services of such executive officer is set forth in footnote (3) to the summary compensation table in this proxy statement. The amounts charged under this ISA are not dependent upon our financial performance. For 2005, our management development and compensation committee reviewed documentation and discussed with management Contran's ISA allocation process, including how Contran determined the necessary personnel, the estimated number of full time employees that would be required to provide the services and the cost of such services under this ISA. The committee then recommended that our board of directors approve the 2005 aggregate service charge for the proposed Contran services to be rendered to us under the ISA after concluding that: o the cost to employ the additional personnel necessary to perform the quality of the services provided by Contran would exceed the proposed 2005 aggregate fee to be charged by Contran under this ISA; and o the cost for such services would be no less favorable than could otherwise be obtained from an unrelated third party for comparable services. Upon receiving the recommendation of our management development and compensation committee that the ISA charge was fair and reasonable to us and our stockholders and that it was in our best interests to continue receiving the services presently provided by Contran, our independent directors, with our other directors abstaining, approved the 2005 aggregate charge to us under this ISA. In making these determinations, our management development and compensation committee relied on their collective business experience and judgment. Other Executive Officers In 2005, our management development and compensation committee administered certain matters regarding the compensation of Ulfert Fiand, H. Joseph Maas and Douglas C. Weaver, three of our executive officers that we or our subsidiaries employ. For 2005, our cash compensation for these executive officers generally consisted of two primary components: base salary and annual operating earnings bonus awards provided by our Share-in-Performance Plan. Base Salaries. Our management establishes base salaries for those executive officers employed by us or our subsidiaries on a position-by-position basis by conducting annual internal reviews of salary levels in an attempt to rank salary and job value to each position. Our management development and compensation committee reviews changes in salaries of our operating management employed by us or our subsidiaries, including those for Messrs. Fiand, Maas and Weaver. In 2005, our management development and compensation committee reviewed increases in the base salaries for Messrs. Fiand, Maas and Weaver based on the expected inflation rate in the applicable country for the employee and further recognition of their promotions and added responsibilities. The 2005 average percentage increase in base salary for all of the operating management employed by us or our subsidiaries was 3.7%. Bonuses. Operating earnings bonus awards under our Share-in-Performance Plan constitute a significant portion of the potential annual cash compensation for Messrs. Fiand, Maas and Weaver. Based on the business plan for the year and management's recommendation, in February 2005, our management development and compensation committee set our 2005 year-end operating earnings goals at three levels: a threshold level, which is the minimum operating earnings level for any award to be made under the Share-in-Performance Plan, a target level and a maximum level. The chief executive officer, with the assistance of our chief operating management consultant and chief financial officer, selected the participants in the Share-in Performance Plan and determined the bonus awards for each participant that would be paid upon our achievement of the operating earnings target at each level. A participating executive officer's cash compensation is designed to result in below competitive compensation levels if the minimum level is not achieved. Pursuant to the Share-in-Performance Plan, if operating earnings fall below the minimum level, no operating earnings bonus award is paid. For 2005, if we were to achieve operating earnings at 85% or higher of the target level but did not achieve the target level, a participant would receive a reduced target level annual operating earnings bonus award, reduced by the pro rata amount by which the achieved operating earnings was less than the target level. As a result of our achieving 2005 operating earnings at the target level, Messrs. Fiand and Maas received the operating earnings bonus awards set forth next to their name for 2005 in the bonus column of the summary compensation table in this proxy statement. In making these determinations regarding base salaries and operating earning bonus awards, our management development and compensation committee relied on their collective business experience and judgment. Common Stock Based Compensation In 2005, our management development and compensation committee administered matters regarding the common stock based compensation of our executive officers. In 2005, management did not recommend any common stock based compensation, and our management development and compensation committee did not grant any such compensation to any executive officers other than annual stock grants to our directors, including our chief executive officer and vice chairman of the board, for their services as directors. Our management development and compensation committee does not currently anticipate granting common stock based compensation to anyone in 2006 other than these annual grants of stock to our directors. See "Compensation of Directors and Executive Officers and Other Information - Compensation of Directors." Deductibility of Compensation Section 162(m) of the Internal Revenue Code of 1986 generally disallows a tax deduction to public companies for non-performance based compensation over $1.0 million paid to the company's chief executive officer and four other most highly compensated executive officers. It is our general policy to structure the performance-based portion of the compensation of our executive officers in a manner that enhances our ability to deduct fully such compensation. The following individuals, in the capacities indicated, hereby submit the foregoing report. R. Gerald Turner Keith R. Coogan George E. Poston Chairman of our Management Member of our Management Member of our Management Development and Development and Compensation Development and Compensation Compensation Committee Committee Committee CERTAIN RELATIONSHIPS AND TRANSACTIONS Relationships with Related Parties. As set forth under "Security Ownership," Harold C. Simmons, through Contran, may be deemed to control us. We and other entities that may be deemed to be controlled by or related to Mr. Simmons sometimes engage in the following: o intercorporate transactions, such as guarantees, management and expense sharing arrangements, shared fee arrangements, tax sharing agreements, joint ventures, partnerships, loans, options, advances of funds on open account and sales, leases and exchanges of assets, including securities issued by both related and unrelated parties; and o common investment and acquisition strategies, business combinations, reorganizations, recapitalizations, securities repurchases and purchases and sales (and other acquisitions and dispositions) of subsidiaries, divisions or other business units, which transactions have involved both related and unrelated parties and have included transactions that resulted in the acquisition by one related party of an equity interest in another related party. We periodically consider, review and evaluate and understand that Contran and related entities periodically consider, review and evaluate such transactions. Depending upon the business, tax and other objectives then relevant and restrictions under indentures and other agreements, it is possible that we might be a party to one or more of such transactions in the future. In connection with these activities, we may consider issuing additional equity securities or incurring additional indebtedness. Our acquisition activities have in the past and may in the future include participation in acquisition or restructuring activities conducted by other companies that may be deemed to be related to Harold C. Simmons. It is our policy to engage in transactions with related parties on terms, in our opinion, no less favorable to us than could be obtained from unrelated parties. Certain directors or executive officers of Contran, CompX, Keystone, NL, TIMET or Valhi also serve as our directors or executive officers. Such relationships may lead to possible conflicts of interest. These possible conflicts of interest may arise from the duties of loyalty owed by persons acting as corporate fiduciaries to two or more companies under circumstances in which such companies may have adverse interests. No specific procedures are in place that govern the treatment of transactions among us and our related entities, although such entities may implement specific procedures as appropriate for particular transactions. In addition, under applicable principles of law, in the absence of stockholder ratification or approval by directors who may be deemed disinterested, transactions involving contracts among companies under common control must be fair to all companies involved. Furthermore, directors owe fiduciary duties of good faith and fair dealing to all stockholders of the companies for which they serve. Intercorporate Services Agreements. We and certain related companies have entered into ISAs. Under the ISAs, employees of one company provide certain services, including executive officer services, to the other company on a fee basis. The services rendered under the ISAs may include executive, management, financial, internal audit, accounting, tax, legal, insurance, risk management, treasury, aviation, human resources, technical, consulting, administrative, office, occupancy and other services as required from time to time in the ordinary course of the recipient's business. The fees paid pursuant to the ISAs are generally based upon an estimate of the time devoted by employees of the provider of the services to the affairs of the recipient and the employer's cost related to such employees, which includes the employees' cash compensation and an overhead component that takes into account the employer's other costs related to the employees. Each of the ISAs in their current form extends on a quarter-to-quarter basis, generally subject to the termination by either party pursuant to a written notice delivered 30 days prior to the start of the next quarter. Because of the large number of companies related to Contran and us, we believe we benefit from cost savings and economies of scale gained by not having certain management, financial and administrative staffs duplicated at each entity, thus allowing certain individuals to provide services to multiple companies but only be compensated by one entity. With respect to a publicly held company that is a party to an ISA, the ISA and the related aggregate annual charge is approved by the independent directors of the company after receiving a recommendation from the company's management development and compensation committee. In 2005, we paid Contran fees of $5.7 million for its services under the ISA between Contran and us. In 2006, we expect to pay Contran fees of $6.3 million for its services under this ISA. We also pay director fees and expenses directly to Messrs. Harold and Glenn Simmons and Watson for their services as our directors. Short-Swing Trading Profits. From December 2004 through April 2005, NL sold shares of our common stock in the open market. From June 2004 through October 2005, Valhi purchased shares of our common stock in the open market. Pursuant to section 16(b) of the Securities Exchange Act, certain of such sales and purchases might be deemed to be matched for purposes of computing short-swing profits. As a result, Valhi made several voluntary payments to us concurrently with a potentially matching transaction aggregating approximately $600,000 and $1.2 million for 2004 and 2005, respectively, which amounts represent the maximum amount of any possible short-swing profits resulting from these transactions. Loans between Related Parties. From time to time, loans and advances are made between us and various related parties pursuant to term and demand notes. These loans and advances are entered into principally for cash management purposes. When we loan funds to related parties, the lender is generally able to earn a higher rate of return on the loan than the lender would earn if the funds were invested in other instruments. While certain of such loans may be of a lesser credit quality than cash equivalent instruments otherwise available to us, we believe that we have evaluated the credit risks involved, and that those risks are reasonable and reflected in the terms of the applicable loans. When we borrow from related parties, we are generally able to pay a lower rate of interest than we would pay if we borrowed from unrelated parties. During 2005, we did not borrow from, or lend to, unconsolidated related parties. Accordingly, we received no interest income on loans to unconsolidated related parties and paid no interest on loans from unconsolidated related parties in 2005. Insurance Matters. We and Contran participate in a combined risk management program. Pursuant to the program, Contran and certain of its subsidiaries and related entities, including us and certain of our subsidiaries and related entities, purchase certain of their insurance policies as a group, with the costs of the jointly owned policies being apportioned among the participating companies. Tall Pines and EWI RE, Inc. provide for or broker these insurance policies. Tall Pines is a captive insurance company wholly owned by Valhi, and EWI RE, Inc. is a reinsurance brokerage and risk management firm wholly owned by NL. Consistent with insurance industry practices, Tall Pines and EWI RE, Inc. receive commissions from insurance and reinsurance underwriters for the policies that they provide or broker. With respect to certain of such jointly owned insurance policies, it is possible that unusually large losses incurred by one or more insureds during a given policy period could leave the other participating companies without adequate coverage under that policy for the balance of the policy period. As a result, Contran and certain of its subsidiaries or related companies, including us, have entered into a loss sharing agreement under which any uninsured loss is shared by those companies who have submitted claims under the relevant policy. We believe the benefits in the form of reduced premiums and broader coverage associated with the group coverage for such policies justify the risks associated with the potential for any uninsured loss. During 2005, we paid premiums of approximately $7.7 million for insurance policies Tall Pines provided or EWI RE, Inc. brokered, including approximately $1.3 million paid by Louisiana Pigment Company, L.P., a partnership of which a wholly owned subsidiary of ours and a subsidiary of Huntsman LLC each own 50%. These amounts principally included payments for reinsurance and insurance premiums paid to unrelated third parties, but also included commissions paid to Tall Pines and EWI RE, Inc. Tall Pines purchases reinsurance for substantially all of the risks it underwrites. In our opinion, the amounts that we, our subsidiaries and Louisiana Pigment Company, L.P. paid for these insurance policies and the allocation among us and our related entities of relative insurance premiums are reasonable and at least as favorable to those we or they could have obtained through unrelated insurance companies or brokers. We expect that these relationships with Tall Pines and EWI RE, Inc. will continue in 2006. Tax Matters. We and our qualifying subsidiaries are members of the consolidated U.S. federal tax return of which Contran is the parent company, which we refer to as the "Contran Tax Group." As a member of the Contran Tax Group and pursuant to certain tax sharing agreements, each of the members and its qualifying subsidiaries compute provisions for U.S. income taxes on a separate company basis using tax elections made by Contran. Pursuant to the tax sharing agreements and using tax elections made by Contran, each of the parties makes payments or receives payments in amounts it would have paid to or received from the U.S. Internal Revenue Service had it not been a member of the Contran Tax Group but instead had been a separate taxpayer. Refunds are generally limited to amounts previously paid under the respective tax sharing agreement. We and our qualifying subsidiaries are also a part of consolidated tax returns filed by Contran in certain U.S. state jurisdictions. The terms of the applicable tax sharing agreements also apply to state payments to these jurisdictions. Under applicable law, we, as well as every other member of the Contran Tax Group, are each jointly and severally liable for the aggregate federal income tax liability of Contran and the other companies included in the group for all periods in which we are included in the group. Valhi has agreed, however, to indemnify us for any liability for income taxes of the Contran Tax Group in excess of our tax liability previously computed and paid by us in accordance with the tax allocation policy. Under certain circumstances, tax regulations could require Contran to treat items differently than we would have treated them on a stand alone basis. In such instances, accounting principles generally accepted in the United States of America require us to conform to Contran's tax elections. In 2005, pursuant to our tax sharing agreement with Valhi and Contran, we paid Valhi approximately $7.7 million in cash. Titanium Dioxide Purchases. From time to time, TIMET purchases titanium dioxide from us. Such purchases are made at prevailing market prices for titanium dioxide and on an individual purchase order basis. During 2005, TIMET's purchases of titanium dioxide from us were at a cost of approximately $114,600. Simmons Family Matters. Certain family members of our chairman of the board, Harold C. Simmons, provide services to us and our subsidiaries pursuant to the ISA between us and Contran. In 2005, James C. Epstein, our chairman's son-in-law, provided risk management services to us and our subsidiaries pursuant to this ISA. The portion of the fees we and our subsidiaries paid to Contran in 2005 pursuant to this ISA for the services of Mr. Epstein was $87,700. We and our subsidiaries expect to pay Contran similar amounts for these services in 2006. Mr. Glenn R. Simmons, the brother of our chairman of the board, also received aggregate compensation of approximately $38,400 in cash and stock from us for his services as our director for 2005 and is expected to continue to receive similar compensation for 2006.

All members of our audit committee meet the independence standards established by the board of directors and the NYSE and promulgated by the SEC under the Sarbanes-Oxley Act of 2002. The amended and restated audit committee charter is attached as Exhibit A to this statement and is also available on our website at www.kronostio2.com under the corporate governance section. Our management is responsible for, among other things, preparing its consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, or "GAAP," establishing and maintaining internal control over financial reporting (as defined in Securities Exchange Act Rule 13a-15(f)) and evaluating the effectiveness of such internal control over financial reporting. Our independent registered public accounting firm is responsible for auditing our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and for expressing an opinion on the conformity of the financial statements with GAAP. Our independent registered public accounting firm is also responsible for auditing our internal control over financial reporting in accordance with such standards and for expressing an opinion on (i) management's assessment of the effectiveness of its internal control over financial reporting and (ii) the effectiveness of its internal control over financial reporting. Our audit committee assists the board of directors in fulfilling its responsibility to oversee management's implementation of our financial reporting process. In its oversight role, our audit committee reviewed and discussed the audited financial statements with management and with PwC, our independent registered public accounting firm for 2005. Our audit committee also reviewed and discussed internal control over financial reporting with management and with PwC. Our audit committee met with PwC and discussed any issues deemed significant by our independent registered public accounting firm, including the required matters to be discussed by Statement of Auditing Standards No. 61, Communication with Audit Committee, as amended. PwC has provided to our audit committee written disclosures and the letter required by Independence Standards Board No. 1, Independence Discussions with Audit Committees, and our audit committee discussed with PwC that firm's independence. Our audit committee also concluded that PwC's provision of non-audit services to us and our related entities is compatible with PwC's independence. Based upon the foregoing considerations, our audit committee recommended to the board of directors that our audited financial statements be included in our 2005 Annual Report on Form 10-K for filing with the SEC. Members of our audit committee of the board of directors respectfully submit the foregoing report. Cecil H. Moore, Jr. George E. Poston Chairman of our Audit Committee Member of our Audit Committee Keith R. Coogan R. Gerald Turner Member of our Audit Committee Member of our Audit Committee INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM MATTERS Independent Registered Public Accounting Firm. PwC served as our independent registered public accounting firm for the year ended December 31, 2005. Our audit committee has appointed PwC to review our quarterly unaudited consolidated financial statements to be included in our Quarterly Reports on Form 10-Q for the first three quarters of 2006. We expect PwC will be considered for appointment to audit our annual consolidated financial statements and internal control over financial reporting for the year ending December 31, 2006. Representatives of PwC are not expected to attend the annual meeting. Fees Paid to PricewaterhouseCoopers LLP. The following table shows the aggregate fees that our audit committee has authorized and PwC has billed or is expected to bill to us for services rendered for 2004 and 2005. Additional audit fees for 2005 may subsequently be authorized and paid to PwC, in which case the amounts disclosed below for fees paid to PwC for 2005 would be adjusted to reflect such additional payments in our proxy statement relating to next year's annual stockholder meeting. In this regard, the audit fees shown below for 2004 have been adjusted from amounts disclosed in our proxy statement for last year's annual stockholder meeting. Type of Fees 2004 2005 - ------------------------------------- ------------- -------------- Audit Fees (1)....................... $ 2,241,259 $ 1,960,000 Audit-Related Fees (2)............... 20,236 19,000 Tax Fees (3)......................... 51,735 24,100 All Other Fees....................... -0- -0- ------------ ------------ Total................................ $ 2,313,230 $ 2,003,100 ============ ============ - ---------- (1) Fees for the following services: (a) audits of consolidated year-end financial statements for each year and audit of internal control over financial reporting; (b) reviews of the unaudited quarterly financial statements appearing in Forms 10-Q for each of the first three quarters of each year; (c) consents and assistance with registration statements filed with the SEC; and (d) normally provided statutory or regulatory filings or engagements for each year. (2) Fees for assurance and related services reasonably related to the audit or review of financial statements for each year. These services included employee benefit plan audits, accounting consultations and attest services concerning financial accounting and reporting standards and advice concerning internal controls. (3) Permitted fees for tax compliance, tax advice and tax planning services. Preapproval Policies and Procedures. For the purpose of maintaining the independence of our independent registered public accounting firm, our audit committee has adopted policies and procedures for the preapproval of audit and permitted non-audit services the firm provides to us or any of our subsidiaries. We may not engage the firm to render any audit or permitted non-audit service unless the service is approved in advance by our audit committee pursuant to the committee's amended and restated preapproval policies and procedures that the committee approved on February 17, 2005. Pursuant to the policy: o the committee must specifically preapprove, among other things, the engagement of our independent registered public accounting firm for audits and quarterly reviews of our financial statements, services associated with certain regulatory filings, including the filing of registration statements with the SEC, and services associated with potential business acquisitions and dispositions involving us; and o for certain categories of permitted non-audit services of our independent registered public accounting firm, the committee may preapprove limits on the aggregate fees in any calendar year without specific approval of the service. These permitted non-audit services include: o audit services, such as certain consultations regarding accounting treatments or interpretations and assistance in responding to certain SEC comment letters; o audit-related services, such as certain other consultations regarding accounting treatments or interpretations, employee benefit plan audits, due diligence and control reviews; o tax services, such as tax compliance and consulting, transfer pricing, customs and duties and expatriate tax services; and o other permitted non-audit services, such as assistance with corporate governance matters and filing documents in foreign jurisdictions not involving the practice of law. Pursuant to the policy, our audit committee has delegated preapproval authority to the chairman of the committee or his designee to approve any fees in excess of the annual preapproved limits for these categories of permitted non-audit services provided by our independent registered public accounting firm. The chairman must report any action taken pursuant to this delegated authority at the next meeting of the committee. For 2005 our audit committee preapproved all PwC's services provided to us or any of our subsidiaries in compliance with the amended and restated preapproval policies and procedures without the use of the SEC's de minimis exception to such preapproval requirement. OTHER MATTERS The board of directors knows of no other business that will be presented for consideration at the meeting. If any other matters properly come before the meeting, the persons designated as agents in the enclosed proxy card or voting instruction form will vote on such matters in accordance with their reasonable judgment. STOCKHOLDER PROPOSALS AND DIRECTOR NOMINATIONS FOR THE 2007 ANNUAL MEETING Stockholders may submit proposals on matters appropriate for stockholder action at our annual stockholder meetings, consistent with rules adopted by the SEC. We must receive such proposals not later than December 14, 2006 to be considered for inclusion in the proxy statement and form of proxy card relating to the annual meeting of stockholders in 2007. Our bylaws require that the proposal must set forth a brief description of the proposal, the name and address of the proposing stockholder as they appear on our books, the number of shares of our common stock the stockholder holds and any material interest the stockholder has in the proposal. The board of directors will consider the director nominee recommendations of our stockholders. Our bylaws require that a nomination set forth the name and address of the nominating stockholder, a representation that the stockholder will be a stockholder of record entitled to vote at the annual stockholder meeting and intends to appear in person or by proxy at the meeting to nominate the nominee, a description of all arrangements or understandings between the stockholder and the nominee (or other persons pursuant to which the nomination is to be made), such other information regarding the nominee as would be required to be included in a proxy statement filed pursuant to the proxy rules of the SEC and the consent of the nominee to serve as a director if elected. The board of directors has no specific minimum qualifications for director candidates. The board of directors will consider a potential director nominee's ability to satisfy the need, if any, for any required expertise on the board of directors or one of its committees. Historically, our management has recommended director nominees to the board of directors. Because under the NYSE listing standards we may be deemed to be a controlled company, the board of directors believes that additional policies or procedures with regard to the consideration of director candidates recommended by its stockholders are not appropriate. For proposals or director nominations to be brought at the 2007 annual meeting of stockholders but not included in the proxy statement for such meeting, our bylaws require that the proposal or nomination must be delivered or mailed to our principal executive offices in most cases no later than February 27, 2007. Proposals and nominations should be addressed to: Corporate Secretary, Kronos Worldwide, Inc., Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697. COMMUNICATIONS WITH THE BOARD OF DIRECTORS Stockholders and other interested parties who wish to communicate with the board of directors or its non-management directors may do so through the following procedures. Such communications not involving complaints or concerns regarding accounting, internal accounting controls and auditing matters related to us may be sent to the attention of our corporate secretary at Kronos Worldwide, Inc., Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697. Provided that any such communication relates to our business or affairs and is within the function of our board of directors or its committees, and does not relate to insignificant or inappropriate matters, such communications, or summaries of such communications, will be forwarded to the chairman of our audit committee, who also serves as the presiding director of our non-management and independent director meetings. Complaints or concerns regarding accounting, internal accounting controls and auditing matters, which may be made anonymously, should be sent to the attention of our general counsel with a copy to our chief financial officer at the same address as our corporate secretary. These complaints or concerns will be forwarded to the chairman of our audit committee. We will keep these complaints or concerns confidential and anonymous, to the extent feasible, subject to applicable law. Information contained in such a complaint or concern may be summarized, abstracted and aggregated for purposes of analysis and investigation. 2005 ANNUAL REPORT ON FORM 10-K A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2005 is included as part of the annual report mailed to our stockholders with this proxy statement and may also be accessed on our website at www.kronostio2.com. ADDITIONAL COPIES Pursuant to an SEC rule concerning the delivery of annual reports and proxy statements, a single set of these documents may be sent to any household at which two or more stockholders reside if they appear to be members of the same family. Each stockholder continues to receive a separate proxy card. This procedure, referred to as householding, reduces the volume of duplicate information stockholders receive and reduces mailing and printing expenses. A number of brokerage firms have instituted householding. Certain beneficial stockholders who share a single address may have received a notice that only one annual report and proxy statement would be sent to that address unless a stockholder at that address gave contrary instructions. If, at any time, a stockholder who holds shares through a broker no longer wishes to participate in householding and would prefer to receive a separate proxy statement and related materials, or if such stockholder currently receives multiple copies of the proxy statement and related materials at his or her address and would like to request householding of our communications, the stockholder should notify his or her broker. Additionally, we will promptly deliver a separate copy of our 2005 annual report or this proxy statement to any stockholder at a shared address to which a single copy of such documents was delivered, upon the written or oral request of the stockholder. To obtain copies of our 2005 annual report or this proxy statement without charge, please mail your request to the attention of Robert D. Graham, corporate secretary, at Kronos Worldwide, Inc., Three Lincoln Centre, 5430 LBJ Freeway, Suite 1700, Dallas, Texas 75240-2697, or call him at 972.233.1700. Kronos Worldwide, Inc. Dallas, Texas April 13, 2006 Appendix A Kronos Worldwide, Inc. Audit Committee Charter Amended and Restated June 30, 2005 -------------- ARTICLE I. PURPOSE The audit committee assists the board of directors' oversight responsibilities relating to the financial accounting and reporting processes and auditing processes of the corporation. The audit committee shall assist in the oversight of: - the integrity of the corporation's financial statements and internal control over financial reporting; - the corporation's compliance with legal and regulatory requirements; - the independent auditor's qualifications and independence; and - the performance of the corporation's internal audit function and independent auditor. ARTICLE II. RELATIONSHIP WITH THE CORPORATION, MANAGEMENT AND THE INDEPENDENT AUDITOR Management is responsible for preparing the corporation's financial statements and maintaining internal control over financial reporting. The corporation's independent auditor is responsible for auditing the corporation's financial statements and internal control over financial reporting. The activities of the audit committee are in no way designed to supersede or alter these traditional responsibilities. The corporation's independent auditor and management have more time, knowledge and detailed information about the corporation than do the audit committee members. Accordingly, the audit committee's role does not provide any special assurances with regard to the corporation's financial statements or internal control over financial reporting. Each member of the audit committee, in the performance of such member's duties, will be entitled to rely in good faith upon the information, opinions, reports or statements presented to the audit committee by any of the corporation's officers, employees, agents, counsel, experts, auditors or any other person as to matters such member reasonably believes are within such other person's professional or expert competence and who has been selected with reasonable care by or on behalf of the corporation, and nothing in this charter will, or will be deemed to, decrease or modify in any manner adverse to any member of the audit committee such member's right to rely on such information, opinions, reports or statements. Nothing in this charter will, or will be deemed to, adversely affect in any manner the rights of members of the committee to indemnification and advancement of expenses under the corporation's certificate of incorporation or bylaws, or under any contract, agreement, arrangement or understanding that may benefit such member. In addition, notwithstanding any other provision of this charter, no provision of this charter will, except to the extent required by applicable law, rule or regulation, be construed to create any duty, liability or obligation on the part of the committee or any of its members. ARTICLE III. AUTHORITY AND RESOURCES The audit committee shall have the authority and resources necessary or appropriate to discharge its responsibilities. The audit committee shall be provided with full access to all books, records, facilities and personnel of the corporation in carrying out its duties. The audit committee shall have the sole authority with regard to the independent auditor as set forth in Article V, and the authority to engage independent counsel and other advisors, as it determines is necessary to carry out its duties. The corporation shall provide appropriate funding, as the audit committee determines is necessary or appropriate in carrying out its duties, for the committee to engage and compensate the independent auditor or legal counsel or other advisors to the committee, and to pay the committee's ordinary administrative expenses. ARTICLE IV. COMPOSITION AND MEETINGS The board of directors shall set the number of directors comprising the audit committee from time to time, which number shall not be less than three. The board of directors shall designate a chairperson of the audit committee.

Simultaneous service on more than three non-affiliated public company audit committees requires a special determination by the board of directors and, if required, disclosure in the annual proxy statement. The board of directors shall determine, in its business judgment, whether the members of the audit committee satisfy all such requirements, regulations or laws. The audit committee shall meet at least quarterly and as circumstances dictate. Regular meetings of the audit committee may be held with or without prior notice at such time and at such place as shall from time to time be determined by the chairperson of the audit committee, any of the corporation's executive officers or the secretary of the corporation.

A majority of the audit committee members shall constitute a quorum for the transaction of the audit committee's business. The audit committee shall act upon the vote of a majority of its members at a duly called meeting at which a quorum is present. Any action of the audit committee may be taken by a written instrument signed by all of the members of the audit committee. Meetings of the audit committee may be held at such place or places as the audit committee shall determine or as may be specified or fixed in the respective notice or waiver of notice for a meeting. Members of the audit committee may participate in audit committee proceedings by means of conference telephone or similar communications equipment by means of which all persons participating in the proceedings can hear each other, and such participation shall constitute presence in person at such proceedings. The audit committee may invite to its meetings any director, any member of management of the corporation and any other persons it deems appropriate in order to carry out its responsibilities. The audit committee may also exclude from its meetings any persons it deems appropriate in order to carry out its responsibilities. ARTICLE V.
