By signing this Statement,  each Reporting  Person agrees that this Statement is
filed on its or his behalf.

         CGI,  TFMC  and  NL  are  direct  holders  of  49.7%,  9.3%  and  0.8%,
respectively,  of the 5,201,780  Class A Shares  outstanding as of June 16, 2005
according  to  information  the  Company  provided  (the  "Outstanding  Class  A
Shares").

         CGI also directly  holds 100%, or 10,000,000  shares,  of the Company's
class B common  stock,  par  value  $0.01 per share  (the  "Class B Shares"  and
collectively with the Class A Shares shall be referred to as the "Shares").  The
description of the relative  rights of the Shares as described in this Statement
is qualified in its entirety by the terms of the Company's restated  certificate
of  incorporation  that is  filed  as  Exhibit  3.1 to  Amendment  No.  1 to the
Company's  Registration  Statement  on Form S-1 filed  with the  Securities  and
Exchange  Commission  on  February  4,  1998  (Reg.  No.  333-42643),  which  is
incorporated  herein by reference.  As a result of its ownership of 49.7% of the
Class A Shares and 100% of the Class B Shares, CGI directly holds  approximately
82.8% of the  combined  voting power (97.5% of the voting power for the election
of directors)  of all classes of voting stock of the Company.  CGI may be deemed
to control the Company.

spouse,  the CMRT,  Valhi and  Harold  C.  Simmons  are the  direct  holders  of
approximately  39.5%,  14.3%,  12.0%. 4.5% and 0.8% of the outstanding shares of

Simmons'  spouse is based on the  1,600,000  shares of  TIMET's 6 3/4%  Series A
Convertible  Preferred Stock, par value $0.01 per share (the "Series A Preferred
Stock"),  that she directly owns, which are convertible into 2,666,666 shares of
TIMET common  stock.  The  ownership of Valhi  includes  24,500  shares of TIMET
common  stock  that  Valhi has the right to acquire  upon  conversion  of 14,700
shares of Series A Preferred  Stock that Valhi  directly  holds.  The percentage
ownership of TIMET common  stock held by each of Ms.  Simmons and Valhi  assumes
the full  conversion of only the shares of Series A Preferred Stock she or Valhi
owns, respectively.

         Valhi is the sole  member  of  Tremont  and may be  deemed  to  control
Tremont.   VGI,  National,   Contran,  the  Foundation,   the  Contran  Deferred
Compensation  Trust No. 2 (the "CDCT No. 2") and the CMRT are the direct holders
of 79.1%, 9.3%, 2.1%, 0.9%, 0.4% and 0.1%, respectively,  of the common stock of

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,

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

trusts  established  for the benefit of certain  children and  grandchildren  of
Harold C. Simmons (the "Trusts"),  of which Mr. Simmons is the sole trustee,  or
held by Mr. Simmons or persons or other entities related to Mr. Simmons. As sole
trustee  of the  Trusts,  Mr.  Simmons  has the  power  to vote and  direct  the
disposition  of the shares of Contran  stock held by the  Trusts.  Mr.  Simmons,
however,  disclaims beneficial ownership of any shares of Contran stock that the

shares  of  Valhi  common  stock.  The  Foundation  is a  tax-exempt  foundation
organized  for  charitable  purposes.  Harold C.  Simmons is the chairman of the

shares of 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  12.0% of the outstanding shares
of TIMET common stock and 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.  Harold C. Simmons is the sole trustee of the CMRT
and a member of the trust investment committee for the CMRT. Mr. Simmons is also
a participant  in one or more of the employee  benefit plans that invest through
the CMRT.

         NL and a subsidiary of NL directly own  3,522,967  shares and 1,186,200
shares,  respectively,  of Valhi common stock.  Pursuant to Delaware law,  Valhi
treats the shares of Valhi common stock that NL and the  subsidiary of NL own as
treasury  stock for voting  purposes and for the purposes of this Statement such
shares are not deemed outstanding.

         Mr.  Harold C.  Simmons is  chairman  of the board and chief  executive
officer of NL, vice chairman of TIMET and chairman of the board of CGI, Tremont,
Valhi, VGI, National, NOA, Dixie Holding, Dixie Rice, Southwest and Contran.

         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 the Shares
that are directly held by CGI and TFMC.  However,  Mr.  Simmons  disclaims  such
beneficial  ownership of the Shares beneficially owned,  directly or indirectly,
by any of such entities.

         Harold C. Simmons' spouse is the direct owner of 20,000 Class A Shares,
69,475 shares of NL common stock and 43,400  shares of Valhi common  stock.  Mr.
Simmons may be deemed to share indirect beneficial  ownership of such Shares. He

         A trust of which Harold C. Simmons and his spouse are  co-trustees  and
the  beneficiaries  of which are the  grandchildren  of his spouse is the direct
holder of 40,000 shares of Valhi common stock. Mr. Simmons disclaims  beneficial
ownership of these shares.

         Certain information  concerning the directors and executive officers of
the Reporting  Persons,  including  offices held by Mr.  Simmons is set forth on

prospects,  and  upon  future  developments  (including,  but  not  limited  to,
performance  of the  Class  A  Shares  in the  market,  availability  of  funds,
alternative  uses of  funds,  and  money,  stock  market  and  general  economic
conditions),  any of the Reporting  Persons or other entities that may be deemed
