             VALHI AND TREMONT ANNOUNCE SIGNING OF MERGER AGREEMENT

     DALLAS, TEXAS AND DENVER, COLORADO . . . November 5, 2002 . . . Valhi, Inc.
(NYSE: VHI) and Tremont  Corporation  (NYSE: TRE) announced today that they have
entered into a definitive  merger agreement for Valhi to acquire the outstanding
shares of Tremont that it does not currently own in a stock-for-stock  exchange.
Each  outstanding  Tremont share not owned by Valhi or certain of its affiliates
will be exchanged for 3.4 shares of Valhi common stock.

     The transaction  has been structured as a tax-free  exchange to the Tremont
stockholders,  except for cash, if any, received for fractional shares.  Tremont
said that the  agreement  was approved by its Board of Directors  based upon the
recommendation  of a special  committee of the Board  comprised of directors who
are not affiliated with Valhi.  Morgan Joseph & Co. Inc. is serving as financial
advisor to the  special  committee  of Tremont  and has issued an opinion to the
special  committee  stating  that the exchange  ratio is fair,  from a financial
point of view, to the Tremont stockholders, other than Valhi and its affiliates.
Valhi's Board of Directors also has approved the transaction.

     The merger is subject to  customary  closing  conditions  and will  require
approval  by the  stockholders  of  Tremont.  Tremont  Group,  Inc.,  which owns
approximately  80% of the  outstanding  shares  of  Tremont  common  stock,  has
indicated  that it intends to vote its shares in favor of approval of the merger
agreement. Valhi owns 80% of Tremont Group and NL Industries, Inc. (NYSE: NL), a
majority-owned  subsidiary  of Valhi,  owns the  remaining  20%. The date of the
Tremont  stockholder  meeting will be established as soon as practical following
the  completion  of  appropriate   filings  with  the  Securities  and  Exchange
Commission.
