Additional Information
Exhibit 99 - Additional Information

NL Industries, Inc. ("NL"), Harold C. Simmons and his
spouse, Annette C. Simmons, are the direct holders of
29.9%, 2.6% and 0.8% respectively, of the outstanding
shares of class A common stock, par value $0.01 per share
(the "Class A Common Stock"), of the issuer.

NL directly holds 100%, or 10,000,000 shares, of the
issuer's Class B Common Stock, par value $0.01 per share
(the "Class B Common Stock", and collectively with the
Class A Common Stock, the "Common Stock").  The description
of the relative rights of the Common Stock contained in the
issuer's restated certificate of incorporation is hereby
incorporated herein by reference to Exhibit 3.1 of the
issuers Registration Statement on Form S-1 (File No. 333-
42643).  As a result of its ownership of all of the Class B
Common Stock, NL currently holds approximately 85.9% of the
combined voting power (98.3% for the election of directors)
of all classes of voting stock of the issuer.

Valhi, Inc. ("Valhi") is the direct holder of 83.1% of the
outstanding common stock of NL.  Valhi Holding Company
("VHC"), the Harold Simmons Foundation, Inc. (the
"Foundation"), the Contran Amended and Restated Deferred
Compensation Trust (the "CDCT") and The Combined Master
Retirement Trust (the "CMRT") are the direct holders of
92.4%, 0.9%, 0.4% and 0.1%, respectively, of the common
stock of Valhi.  Valhi Group, Inc. ("VGI"), National City
Lines, Inc. ("National") and Contran Corporation
("Contran") are the direct holders of 87.4%, 10.3% and
2.3%, respectively, of the outstanding common stock of VHC.
National, NOA, Inc. ("NOA") and Dixie Rice Agricultural
Corporation, Inc. ("Dixie Rice") are the direct holders of
approximately 73.3%, 11.4% and 15.3%, respectively, of the
outstanding common stock of VGI.  Contran and NOA are the
direct holders of approximately 85.7% and 14.3%,
respectively, of the outstanding common stock of National.
Contran and Southwest Louisiana Land Company, Inc.
("Southwest") are the direct holders of approximately 49.9%
and 50.1%, respectively, of the outstanding common stock of
NOA.  Contran is the direct holder of 100% of the outstanding
common stock of Dixie Rice and 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, or is
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 Trusts hold.

The Foundation directly holds approximately 0.9% of the
outstanding shares of Valhi common stock.  The Foundation
is a tax-exempt foundation organized for charitable
purposes.  Harold C.  Simmons is the chairman of the board
of the Foundation.

The CDCT directly holds approximately 0.4% of the
outstanding Valhi common stock.  U.S.  Bank National
Association serves as the trustee of the CDCT.  Contran
established the CDCT as an irrevocable rabbi trust to
assist Contran in meeting certain deferred compensation
obligations that it owes to Harold C.  Simmons.  If the
CDCT 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, Contran (i) retains the power to vote the shares of
Valhi common stock held directly by the CDCT, (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.  Contran sponsors
the CMRT, which permits the collective investment by master
trusts that maintain the assets of certain employee benefit
plans Contran 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.

NL and a subsidiary of NL directly own 3,522,967 shares and
1,186,200 shares, respectively, of Valhi common stock.  As
already discussed, Valhi is the direct holder of
approximately 83.1% of the outstanding common stock of NL.
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 of Valhi,
VHC, VGI, National, NOA, Dixie Rice, Southwest and Contran
and chairman of the board and chief executive officer of
NL.

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 of Class A or Class B
Common Stock that are directly held by NL.  However, Mr.
Simmons disclaims such beneficial ownership of the shares
of Class A or Class B Common Stock beneficially owned
directly by NL.

Harold C.  Simmons' spouse is the direct owner of 20,000
shares of Class A Common Stock, 269,775 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 securities.  Mr. Simmons disclaims beneficial
ownership of all securities that his spouse holds directly.

Mr. Harold C.  Simmons is the direct owner of 66,900 shares
of Class A Common Stock, 555,300 shares of NL common stock
and 3,383 shares of Valhi common stock.

The Annette Simmons Grandchildren's Trust (the
"Grandchildren's Trust"), of which Harold C. Simmons and
his spouse are trustees and the beneficiaries are the
grandchildren of his spouse, is the direct holder of 36,500
shares of the common stock of Valhi.  Mr. Simmons, as co-
trustee of this trust, has the power to vote and direct the
disposition of the shares of Valhi common stock the trust
holds.  Mr. Simmons disclaims beneficial ownership of any
shares that this trust holds.

TIMET Finance Management Company ("TFMC") is the direct holder of
0.5% of the outstanding common stock of NL.  Titanium
Metals Corporation ("TIMET") is the direct holder of 100%
of the outstanding common stock of TFMC.  VHC, Annette C.
Simmons, the CMRT, Harold C. Simmons, NL, Valhi, the Foundation,
the CDCT and The Annette Simmons Grandchildren's Trust (the
"Grandchildren's Trust") are the holders of approximately
30.9%, 11.6%, 9.5%, 3.2%, 0.9%, 0.5%, 0.2%, 0.1% and
less than 0.1%, respectively, of the outstanding shares of
TIMET common stock.  The ownership of Ms. Simmons includes
20,824,200 shares of TIMET common stock that she has the
right to acquire upon exercise of 1,561,815 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.  The percentage ownership of TIMET
common stock held by Ms. Simmons assumes the full
conversion of only the shares of Series A Preferred Stock
owned by her.  The percentage ownership of TIMET common stock
owned by NL includes 0.3% of the outstanding shares of TIMET
common stock that is owned by a subsidiary of NL.
