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

     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

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 the

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.

control certain of such entities and (b) Mr. Simmons and certain of such

entities may be deemed to possess indirect beneficial ownership of, and a

pecuniary interest in, shares of common stock directly held by certain of

such other entities. However, Mr. Simmons disclaims such beneficial

ownership of, and such pecuniary interest in, such shares beneficially

owned, directly or indirectly, by any of such entities, except to the

extent of his vested beneficial interest, if any, in the shares the CDCT

holds directly.

subsidiary of NL) and Kronos directly own 14,372,970 shares and 1,724,916

statement. As already stated, Valhi is the direct holder of approximately

83.0% of the outstanding shares of common stock of NL and 50.0% of the

outstanding shares of Kronos common stock.  As a result of Valhi's direct

and indirect ownership of NL and Kronos, the reporting persons further

understand that, pursuant to Delaware law, Valhi treats the shares of

Valhi common stock that NL and Kronos own as treasury stock for voting

purposes. For the purposes of this statement, such shares of Valhi common

stock that NL and Kronos hold directly are not deemed outstanding.



     Annette C. Simmons is the wife of Harold C. Simmons.  Mr. Simmons

may be deemed to share indirect beneficial ownership of the shares that

his wife holds directly.  Mr. Simmons disclaims beneficial ownership of

all securities that his wife holds directly.  Mrs. Simmons disclaims
