Association ("U.S.  Bank") and Societe Generale,  Southwest Agency ("SoGen," and
collectively  with Comerica and U.S. Bank,  the "Banks"),  for itself and as the

Valhi under the Valhi Credit  Facility up to an  aggregate  of $50 million.  The
maximum amount that Valhi could borrow under the Valhi Credit  Facility could be
increased to a maximum of $100  million,  if and when  additional  participating
banks  committed  to loan  additional  amounts to Valhi  under the Valhi  Credit
Facility.

     As of November 5, 1999,  Valhi and the Banks entered into a First Amendment
Agreement  extending the maturity date of the Valhi Credit  Facility to November
3, 2000.  As of  November  3, 2000,  Valhi and the Banks  entered  into a Second
Amendment Agreement providing for, among other things:

          (a)  U.S. Bank National  Association ("U.S.  Bank") replacing SoGen as
               agent, issuing bank and arranger of the Valhi Credit Facility;

          (d)  The  maturity  date  being  extended  from  November  3,  2000 to

prime  rate or  0.50%  over  the  federal  funds  rate or  (ii)  for  eurodollar
borrowings,  at a rate of 1.5% over the relevant  rate  (adjusted  for statutory
reserve  requirements  for  eurodollar  liabilities)  at which  deposits in U.S.
dollars are offered to U.S.  Bank's London  office in the  interbank  eurodollar
market  (the one,  two,  three or six month  rate at  Valhi's  option).  Valhi's
obligations  under the Valhi  Credit  Facility  are  collateralized  by  certain
Shares. As of January 11, 2002, Valhi had borrowed $35.0 million under the Valhi
Credit  Facility and had pledged  29,974,610  Shares  (61.3% of the  Outstanding
Shares) under the Valhi Credit  Facility.  The aggregate amount that Valhi could
borrow  under the Valhi  Credit  Facility  is limited to  one-third  of the fair
market value of the pledged  Shares.  The foregoing  summary of the Valhi Credit
Facility is qualified in its entirety by reference to Exhibits 1, 2, 3, 4, 5 and
6 to this Statement.

     The information included in Item 4 of this Statement is hereby incorporated
herein by reference.

     Other than as set forth  above,  none of the  Reporting  Persons or, to the
best knowledge of such persons, any person named in Schedule B to this Statement
has  any  contract,   arrangement,   understanding  or  relationship  (legal  or
