                                 TO SCHEDULE 13D

     This amended  statement on Schedule 13D (this  "Statement")  relates to the

a  Delaware  corporation  (the  "Company").  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(a) is amended as follows.

         (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.
("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 Harold Simmons
Foundation,  Inc. (the  "Foundation")  and the Combined Master  Retirement Trust
(the  "CMRT") 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.

         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. VGI,
National, Contran, the Foundation, the Contran Deferred Compensation Trust No. 2
(the  "CDCT No. 2") and the CMRT are the direct  holders of 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.  Dixie Rice is the  direct  holder of 100% of the  outstanding

may be deemed to control  Dixie  Rice.  Contran  is the holder of  approximately
88.9% of the outstanding  common stock of Southwest and may be deemed to control
Southwest.

         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
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.

         Valmont Insurance  Company  ("Valmont") and a subsidiary of NL 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 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.
