(a) This Statement is filed (i) by Tremont Group, Inc. ("TGI"), NL Industries, Inc. ("NL") and Valhi, Inc. ("Valhi") as the direct holders of Shares, (ii) by virtue of the direct and indirect ownership of securities of TGI, by Valhi, NL, Valhi Group, Inc. ("VGI"), National City Lines, Inc.

Simmons (collectively, the "Reporting Persons"). By signing this Statement, each Reporting Person agrees that this Statement is filed on its or his behalf. TGI, NL and Valhi are the direct holders of approximately 80.0%, 0.1% and 0.1%, respectively, of the 6,424,858 Shares outstanding as of November 11, 2002 according to the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2002 (the "Outstanding Shares"). Together, TGI, NL and Valhi may be deemed to control the Company. Valhi and NL are the direct holders of approximately 80.0% and 20.0%, respectively, of the outstanding common stock of TGI. Together Valhi and NL may be deemed to control TGI. Valhi and the Company are the direct holders of approximately 63.2% and 21.4%, respectively, of the outstanding common stock of NL and together may be deemed to control NL.

Substantially all of Contran's outstanding voting stock is held by trusts established for the benefit of certain children and grandchildren of Harold C.

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.

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 owed 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.

Pursuant to Delaware law, Valhi treats the shares of Valhi common stock that Valmont and the subsidiary of NL 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, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest and Contran. Mr. Simmons is also chairman of the board of NL and Valhi and a director of the Company. 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 69,475 shares of NL common stock. Mr. Simmons may be deemed to share indirect beneficial ownership of such shares. Mr. Simmons disclaims all such beneficial ownership. Item 3. Source and Amount of Funds or Other Consideration. Item 3 is amended as follows. The information included in Item 4 to this Statement is hereby incorporated herein by reference. Item 4. Purpose of Transaction. No change to Item 4 except for the following: On November 4, 2002, Valhi and the Company entered into an Agreement and Plan of Merger, as amended, for Valhi to acquire the Company in a stock-for-stock exchange (the "Merger Agreement"). The description of the Merger Agreement contained in this Statement is qualified in its entirety by reference to Appendix A to the Registration Statement on Form S-4 (Reg. No. 333-101244) filed by Valhi on November 15, 2002 (the "Registration Statement") with the Securities and Exchange Commission (the "Commission"), which Appendix A is incorporated herein by reference. Pursuant to the Merger Agreement, a wholly owned subsidiary of Valhi will merge (the "Merger") with and into the Company with the Company being the surviving entity. In the Merger, each stockholder of the Company, other than Valhi and TGI, will receive 3.4 shares of Valhi common stock for each outstanding Share held by such stockholder. The Merger Agreement provides that the Company's stockholders will receive cash in lieu of Valhi issuing any fractional shares in the Merger. The Merger is subject to customary closing conditions and will require the approval of the holders of a majority of the outstanding Shares. TGI has indicated that it intends to vote its Shares in favor of adoption of the Merger Agreement. Therefore, assuming that TGI so votes its Shares, the Merger Agreement will be adopted and the Merger will be completed. On November 5, 2002, Valhi and the Company issued a joint press release disclosing the execution of the Merger Agreement. A copy of the press release is incorporated herein by reference to the Form 425 filed by Valhi with the Commission on November 5, 2002. On November 15, 2002, Valhi filed the Registration Statement to register the shares of Valhi common stock to be issued in the Merger. The prospectus included in the Registration Statement also serves as a proxy statement pursuant to which the Company's board of directors plans to solicit proxies from the Company's stockholders to adopt the Merger Agreement. The information contained in the Registration Statement under the captions "The Merger - General Description," "- Background of the Merger," "- Valhi's Reasons for the Merger," "- Ownership Interests in Valhi Common Stock After the Merger," "- Management and Operations After the Merger," "- Litigation Relating to the Merger" and "Related Transactions to Be Completed Immediately Prior to and as Soon as Possible Following the Completion of the Merger," is incorporated herein by reference. The information contained in the prospectus/proxy statement that is a part of the Registration Statement is not complete and may be changed. Valhi cannot sell the securities to be issued in the Merger until the Commission declares the Registration Statement effective. The prospectus/proxy statement that is a part of the Registration Statement is not an offer to sell such securities and it is not soliciting an offer to buy such securities in any state where offers or sales are not permitted. The prospectus/proxy statement that is a part of the Registration Statement is not soliciting material from the Company's board of directors in connection with the solicitation of proxies for the adoption of the Merger Agreement. 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. Item 5. Interest in Securities of the Issuer.
