Items 2, 3, 4, 5, 6 and 7 of this Statement are hereby amended as set forth below. Item 2. Identity and Background. Item 2 is amended as follows: (a) This Statement is filed (i) by Tremont Corporation ("Tremont") and Valhi, Inc. ("Valhi") as the direct holders of Shares, (ii) by virtue of the direct and indirect ownership of securities of Tremont or Valhi (as described below in this Statement), by Tremont Group, Inc. ("TGI"), Tremont Holdings, LLC ("TRE Holdings"), Valhi Group, Inc. ("VGI"), National City Lines, Inc. ("National"), NOA, Inc. ("NOA"), Dixie Holding Company ("Dixie Holding"), Dixie Rice Agricultural Corporation, Inc. ("Dixie Rice"), Southwest Louisiana Land Company, Inc. ("Southwest"), Contran Corporation ("Contran"), The Combined Master Retirement Trust (the "CMRT") and the Harold Simmons Foundation, Inc. (the "Foundation") and (iii) by virtue of his positions with Contran and certain of the other entities (as described in this Statement), by Harold C. Simmons (collectively, the "Reporting Persons"). By signing this Statement, each Reporting Person agrees that this Statement is filed on its or his behalf. Valhi and Tremont are the direct holders of approximately 61.8% and 21.0%, respectively, of the 48,760,384 Shares outstanding as of July 30, 2002 according to information provided by the Company (the "Outstanding Shares"). Together, Valhi and Tremont may be deemed to control the Company. TGI, TRE Holdings and Valhi are the holders of approximately 80.0%, 0.1% and 0.1%, respectively, of the outstanding shares of common stock of Tremont and together may be deemed to control Tremont. Valhi and TRE Holdings are the direct holders of approximately 80.0% and 20.0%, respectively, of the outstanding common stock of TGI. Together Valhi and TRE Holdings may be deemed to control TGI. The Company is the sole member of TRE Holdings and may be deemed to control TRE Holdings. VGI, National, Contran, the Foundation, the Contran Deferred Compensation Trust No. 2 (the "CDCT No. 2") and the CMRT are the direct holders of approximately 80.6%, 9.5%, 2.1%, 1.4%, 0.4% and 0.1%, respectively, of the common stock of Valhi. Together, VGI, National and Contran may be deemed to control Valhi. National, NOA and Dixie Holding are the direct holders of approximately 73.3%, 11.4% and 15.3%, respectively, of the outstanding common stock of VGI. Together, National, NOA and Dixie Holding may be deemed to control VGI. Contran and NOA are the direct holders of approximately 85.7% and 14.3%, respectively, of the outstanding common stock of National and together may be deemed to control National. Contran and Southwest are the direct holders of approximately 49.9% and 50.1%, respectively, of the outstanding common stock of NOA and together may be deemed to control NOA.

Substantially all of Contran's outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Harold C. Simmons (the "Trusts"), of which Mr. Simmons is the sole trustee. As sole trustee of each of the Trusts, Mr. Simmons has the power to vote and direct the disposition of the shares of Contran stock held by each of the Trusts. Mr. Simmons, however, disclaims beneficial ownership of any shares of Contran stock that the Trusts hold. The Foundation directly holds approximately 1.4% 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. The CDCT No. 2 directly holds approximately 0.4% of the outstanding Valhi common stock. U.S. Bank National Association serves as the trustee of the CDCT No. 2. 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 is obligated to satisfy the balance of such obligations as they come due. Pursuant to the terms of the CDCT No. 2, Contran (i) retains the power to vote the shares of Valhi common stock held directly by the CDCT No. 2, (ii) retains dispositive power over such shares and (iii) may be deemed the indirect beneficial owner of such shares. The CMRT directly holds approximately 0.1% of the outstanding shares of Valhi common stock. Valhi established the CMRT as a trust to permit the collective investment by master trusts that maintain the assets of certain employee benefit plans Valhi and related companies adopt. Mr. Simmons is the sole trustee of the CMRT and a member of the trust investment committee for the CMRT. Mr. Simmons is a participant in one or more of the employee benefit plans that invest through the CMRT. Valmont Insurance Company ("Valmont") and a subsidiary of the Company directly own 1,000,000 shares and 1,186,200 shares, respectively, of Valhi common stock. Valhi is the direct holder of 100% of the outstanding common stock of Valmont and may be deemed to control Valmont. Pursuant to Delaware law, Valhi treats the shares of Valhi common stock that Valmont and the subsidiary of the Company own as treasury stock for voting purposes and for the purposes of this Statement are not deemed outstanding. Mr. Harold C. Simmons is chairman of the board and chief executive officer of TGI, Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest and Contran. Mr. Simmons is also chairman of the board of the Company and a director of Tremont. By virtue of the holding of the offices, the stock ownership and his service as trustee, all as described above, (a) Mr. Simmons may be deemed to control the entities described above and (b) Mr. Simmons and certain of such entities may be deemed to possess indirect beneficial ownership of Shares directly held by certain of such other entities. However, Mr. Simmons disclaims beneficial ownership of the Shares beneficially owned, directly or indirectly, by any of such entities. Harold C. Simmons' spouse is the direct owner of 69,475 Shares. Mr. Simmons may be deemed to share indirect beneficial ownership of such Shares. Mr. Simmons disclaims all such beneficial ownership. Certain information concerning the directors and executive officers of the Reporting Persons, including offices held by Mr. Simmons is set forth on Schedule B attached hereto and incorporated herein by reference. (b) The business addresses of the directors and executive officers of the Reporting Persons are set forth on Schedule B to this Statement and incorporated herein by reference. (d) None of the Reporting Persons or, to the best knowledge of such persons, any of the persons named in Schedule B to this Statement has been convicted in a criminal proceeding in the past five years (excluding traffic violations or similar misdemeanors). (e) None of the Reporting Persons or, to the best knowledge of such persons, any person named in Schedule B to this Statement, was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. (f) Harold C. Simmons and all the persons named on Schedule B to this Statement are citizens of the United States, except as otherwise indicated on such Schedule. Item 3. Source and Amount of Funds or Other Consideration. Item 3 is amended as follows. The Reporting Persons understand that the funds required by the persons named in Schedule B to this Statement to acquire Shares (other than Shares Harold C. Simmons may be deemed to own beneficially) were from such person's personal funds. Item 4. Purpose of Transaction. No change to Item 4 except for the following: On July 26, 2002, Valhi sent a letter to the board of directors of Tremont proposing (the "Proposal") a merger of Valhi and Tremont pursuant to which stockholders of Tremont, other than Valhi, would receive between 2 and 2.5 shares of Valhi's common stock, par value $0.01 per share, for each outstanding share of Tremont common stock held. A copy of the letter is attached hereto as Exhibit 1 and incorporated herein by reference (the "Proposal Letter"). On July 26, 2002, Valhi issued a press release announcing the Proposal. A copy of the press release is attached hereto as Exhibit 2 and incorporated herein by reference. On July 29, 2002, Tremont issued a press release announcing its receipt of the Proposal Letter and that Tremont expects its board of directors to form a special committee comprised of board members unrelated to Valhi to review the Proposal. A copy of the press release is attached hereto as Exhibit 3 and incorporated herein by reference. Beginning on July 29, 2002, several purported stockholder class action lawsuits were filed against Tremont and Valhi and Tremont's directors on behalf of Tremont's stockholders other than Valhi and its affiliates. The complaints allege, among other things, that the defendants have breached fiduciary duties owed to Tremont's stockholders other than Valhi and its affiliates with respect to the Proposal. Each of the complaints seeks class certification and to enjoin the consummation of the Proposal and recover attorneys' fees and expenses. The complaints also seek an award of damages if the Proposal is consummated. None of the defendants has yet responded to the lawsuits. There is no assurance that any transaction will be consummated under the terms of the Proposal or otherwise. Depending upon their evaluation of the Company's business and prospects, and upon future developments (including, but not limited to, performance of the Shares in the market, availability of funds, alternative uses of funds, the Reporting Persons' tax planning objectives and money, stock market and general economic conditions), any of the Reporting Persons or other entities or persons that may be deemed to be affiliated with Contran may from time to time purchase Shares, and any of the Reporting Persons or other entities or persons that may be deemed to be affiliated with Contran may from time to time dispose of all or a portion of the Shares held by such entity or person, or cease buying or selling Shares. Any such additional purchases or sales of the Shares may be in open market or privately negotiated transactions or otherwise. As described under Item 2, Harold C. Simmons, through Contran, may be deemed to control the Company. The information included in Item 6 of this Statement is incorporated herein by reference. The Reporting Persons understand that prior purchases of Shares by each of the persons named in Schedule B to this Statement (other than Harold C. Simmons) were made for the purpose of each such person's personal investment. Certain of the persons named in Schedule B to this Statement, namely David B. Garten, Robert D. Hardy, J. Landis Martin, Thomas P. Stafford, Glenn R. Simmons, Harold C. Simmons and Steven L. Watson, are directors or officers of the Company and may acquire Shares from time to time pursuant to benefit plans that the Company sponsors or other compensation arrangements with the Company. Except as described in this Item 4, none of the Reporting Persons nor, to the best knowledge of such persons, any other person named in Schedule B to this Statement has formulated any plans or proposals which relate to or would result in any matter required to be disclosed in response to paragraphs (a) through (j) of Item 4 of Schedule 13D. Item 5. Interest in Securities of the Issuer. Item 5 is amended as follows: (a) Valhi, Tremont, Harold C. Simmons' spouse and Harold C. Simmons are the direct beneficial owners of 30,135,390, 10,215,541, 69,475 and 5,000 Shares, respectively. In addition, Harold C. Simmons holds stock options exercisable for 10,000 Shares, 8,000 of which stock options vest within 60 days of the filing of this Statement. By virtue of the relationships described under Item 2 of this Statement: (1) Tremont, TGI and TRE Holdings may each be deemed to be the beneficial owner of the 10,215,541 Shares (approximately 21.0% of the Outstanding Shares) directly held by Tremont; (2) Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest, Contran, the CMRT and the Foundation may each be deemed to be the beneficial owner of the 40,350,931 Shares (approximately 82.8% of the Outstanding Shares) directly held by Valhi and Tremont; and (3) Harold C. Simmons may be deemed to be the beneficial owner of the 40,435,406 Shares (approximately 82.9% of the Outstanding Shares) directly held by Valhi, Tremont, Mr. Simmons' spouse and himself and including the 10,000 Shares that Mr. Simmons can acquire by exercise of stock options (8,000 of which stock options will vest within 60 days of the filing of this Statement). Mr. Simmons disclaims beneficial ownership of all Shares, except the 5,000 Shares that he holds directly and the 10,000 Shares that Mr. Simmons can acquire by exercise of stock options, 8,000 of which vest within 60 days of the filing of this Statement. The Reporting Persons understand, based on ownership filings with the Securities and Exchange Commission (the "Commission") or upon information provided by the persons listed on Schedule B to this Statement, that such persons may be deemed to own personally and beneficially the Shares as indicated on Schedule C to this Statement. (b) By virtue of the relationships described in Item 2: (1) Tremont, TGI and TRE Holdings may each be deemed to share the power to vote and direct the disposition of the 10,215,541 Shares that Tremont directly holds; (2) Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest, Contran, the CMRT and the Foundation may each be deemed to share the power to vote and direct the disposition of the 40,350,931 Shares that Valhi and Tremont directly hold; (3) Harold C. Simmmons may be deemed to share the power to vote and direct the disposition of the 40,420,406 Shares that Valhi, Tremont and Mr. Simmons' spouse directly hold; and (4) Harold C.

(d) Each of Valhi, Tremont, Harold C. Simmons' spouse and Harold C.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer. Item 6 is amended as follows: Valhi is a party to a Credit Agreement (the "Valhi Credit Facility"), as amended, with Comerica Bank, PNB Financial Bank, Texas Capital Bank and U.S. Bank National Association (collectively, the "Banks"). The Banks have committed to loan to Valhi under the Valhi Credit Facility up to an aggregate of $72.5 million. The maximum amount that Valhi could borrow under the Valhi Credit Facility could be increased to a maximum of $100 million, if and when additional participating banks committed to loan additional amounts to Valhi under the Valhi Credit Facility. The maturity date for the Valhi Credit Agreement is November 1, 2002. Borrowings under the Valhi Credit Facility bear interest (i) for base rate borrowings, at the greater of the rate announced publicly from time to time by U.S. Bank as its prime rate or 0.50% over the federal funds rate or (ii) for eurodollar borrowings, at a rate of 1.5% over the relevant rate (adjusted for statutory reserve requirements for eurodollar liabilities) at which deposits in U.S. dollars are offered to U.S. Bank's London office in the interbank eurodollar market (the one, two, three or six month rate at Valhi's option). Valhi's obligations under the Valhi Credit Facility are collateralized by certain Shares. As of August 2, 2002, Valhi had borrowed $35.0 million under the Valhi Credit Facility, approximately $1.1 million of letters of credit were outstanding under the Valhi Credit Facility and Valhi had pledged 29,974,610 Shares (61.5% of the Outstanding Shares) under the Valhi Credit Facility. The aggregate amount that Valhi could borrow under the Valhi Credit Facility is limited to one-third of the fair market value of the pledged Shares. The foregoing summary of the Valhi Credit Facility is qualified in its entirety by reference to Exhibits 4 through 10 to this Statement. The information included in Item 4 of this Statement is hereby incorporated herein by reference. Other than as set forth above, none of the Reporting Persons or, to the best knowledge of such persons, any person named in Schedule B to this Statement has any contract, arrangement, understanding or relationship (legal or otherwise) with any person with respect to securities of the Company, including, but not limited to, transfer or voting of any such securities, finder's fees, joint ventures, loans or option arrangements, puts or calls, guarantees of profits, division of profits or losses, or the giving or withholding of proxies.
