     of Class A Shares and his  positions  with Contran and certain of the other

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

5,195,780 Class A Shares  outstanding as of May 3, 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

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.

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
disclaims all such beneficial ownership.

     Harold C.  Simmons is the  direct  owner of 40,700  Class A Shares,  30,800
shares of NL common stock (including options  exercisable for 6,000 shares of NL
