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

                            FORM ACCESSION AGREEMENT


         This Accession Agreement dated as of January 15, 2002 (this "Agreement)
is executed and delivered in connection  with the Credit  Agreement  dated as of
November 6, 1998,  among Valhi,  Inc.,  a Delaware  corporation,  the  financial
institutions parties thereto, as Banks, U.S. Bank National  Association,  as the
Administrative  Agent, the Issuing Bank, and the Arranger (as modified from time
to time, the "Credit  Agreement," the capitalized terms of which are used herein
unless otherwise defined herein).

         Whereas,  as contemplated by Section 2.18 of the Credit Agreement,  the
Borrower  has  requested   that  the  aggregate   Commitments  be  increased  to
$70,000,000; and

         Whereas,  PNB  Financial  Bank has  agreed to  become a Bank  under the
Credit Agreement with a Commitment on $15,000,000;

         Now therefore the parties hereto agree as follows:

         1. PNB Financial Bank shall, on and as of the Effective Date (as herein
defined)  become  a  Bank  under  the  Credit  Agreement  with a  Commitment  of
$15,000,000.

         2. PNB  Financial  Bank hereby (i) confirms that it has received a copy
of the  Credit  Agreement,  together  with  copies of the  financial  statements
referred to in Section  4.01(e) thereof and such other documents and information
as it has deemed  appropriate  to make its own credit  analysis  and decision to
enter into this Agreement;  (ii) agrees that it will,  independently and without
reliance  upon the Agent or any other  Bank,  and  based on such  documents  and
information as it shall deem  appropriate at the time,  continue to make its own
credit  decisions in taking or not taking  action under the Credit  Agreement or
any other Credit Document;  (iii) appoints and authorizes the Agent to take such
action as agent on its  behalf  and to  exercise  such  powers  under the Credit
Agreement  and any other  Credit  Document as are  delegated to the Agent by the
terms thereof,  together with such powers as are reasonably  incidental thereto;
(iv) agrees that it will  perform all of the  obligations  which by the terms of
the Credit  Agreement or any other Credit  Document are required to be performed
by it as a Bank; (v) specifies as its Applicable Lending Offices the offices set
forth in Annex A of this Agreement.

         3. The  address  for  notices  to PNB  Financial  Bank under the Credit
Agreement is set forth on Annex A to this Agreement.

         4. On the Effective Date,  notwithstanding  anything to the contrary in
the Credit  Agreement,  PNB  Financial  Bank shall be a "Bank" for all  purposes
under the Credit Agreement.

         5. On the Effective Date, the Borrower shall execute and deliver to PNB
Financial Bank a Note in the form of Exhibit A attached to the Credit Agreement,
which  Note  shall be dated as of the  Effective  Date,  shall be payable to the
order of PNB Financial Bank, and shall be in the amount of $15,000,000.

         6. The date this Agreement  becomes  effective (the  "Effective  Date")
shall be January 15, 2002,  provided that on such date (i) no Default shall have
occurred and be continuing  and (ii) the Borrower  shall prepay any  outstanding
Advances which were made by the Banks prior to such date.

         7. In connection  with this Agreement,  the Borrower hereby  represents
and warrants that all of the  representations  and  warranties  set forth in the
Credit  Documents  (other  than those  made as of a specific  date) are true and
correct in all material respects on and as of the date of this Agreement, and no
Default has occurred.

         8. This  Agreement  shall be governed by, and construed and enforced in
accordance with, the laws of the State of New York.


                     [REMAINDER OF PAGE INTENTIONALLY BLANK]


         IN WITNESS  WHEREOF this  Agreement is executed and delivered as of the
date first mentioned above.
