                                AMENDMENT NO. 60
                                TO SCHEDULE 13D

     This amended statement on Schedule 13D (collectively, this "Statement")
relates to the common stock, $0.01 par value per share (the "Shares"), of Valhi,
Inc., a Delaware corporation (the "Company").  Items 2, 3, 4, 5, 6 and 7 of this
Statement are hereby amended as set forth below.

Item 2.   Identity and Background

     No change except for the addition of the following:

     (a)  This Statement is filed by (i) Valhi Group, Inc. ("VGI"), National
City Lines, Inc. ("National") and Contran Corporation ("Contran") as the direct
holders of Shares, (ii) by virtue of the direct and indirect ownership of
securities of VGI and National (as described below in this Statement), NOA, Inc.
("NOA"), Dixie Holding Company ("Dixie Holding"), Dixie Rice Agricultural
Corporation, Inc. ("Dixie Rice") and Southwest Louisiana Land Company, Inc.
("Southwest") and (iii) by virtue of his positions with Contran and certain of
the other entities (as reported on this Statement), Harold C. Simmons
(collectively, the "Reporting Persons").  By signing this Statement, each
Reporting Person agrees that this Statement is filed on its or his behalf.

     VGI, National and Contran are the direct holders of approximately 74.7%,
10.0% and 7.6%, respectively, of the 114,638,214 Shares outstanding as of
February 6, 1998 according to information furnished by the Company (the
"Outstanding Shares").  Together, VGI, National and Contran may be deemed to
control the Company.  National, NOA and Dixie Holding are the direct holders of
approximately 73.3%, 11.4% and 15.3%, respectively, of the outstanding common
stock of VGI.  Together, National, NOA and Dixie Holding may be deemed to
control VGI.  Contran and NOA are the direct holders of approximately 85.7% and
14.3%, respectively, of the outstanding common stock of National and together
may be deemed to control National.  Contran and Southwest are the direct holders
of approximately 49.9% and 50.1%, respectively, of the outstanding common stock
of NOA and together may be deemed to control NOA. Dixie Rice is the holder of
100% of the outstanding common stock of Dixie Holding and may be deemed to
control Dixie Holding.  Contran is the direct holder of approximately 88.7% and
54.3% of the outstanding common stock of Southwest and Dixie Rice, respectively,
and may be deemed to control Southwest and Dixie Rice.

     Mr. Harold C. Simmons is chairman of the board, president and chief
executive officer of VGI, National, NOA, Dixie Holding and Contran.  Mr. Simmons
is also chairman of the board and chief executive officer of Dixie Rice and
Southwest.

     Substantially all of Contran's outstanding voting stock is held by two
trusts, the Harold C. Simmons Family Trust No. 1 dated January 1, 1964 and the
Harold C. Simmons Family Trust No. 2 dated January 1, 1964 (together, the
"Trusts"), established for the benefit of Mr. Simmons' children and
grandchildren, of which Mr. Simmons is the sole trustee.  As the sole trustee of
each of the Trusts, Mr. Simmons has the power to vote and direct the disposition
of the shares of Contran stock held by each of the Trusts.  Mr. Simmons,
however, disclaims beneficial ownership of such shares.

     The Contran Deferred Compensation Trust No. 2 (the "CDCT No. 2") directly
holds approximately 0.2% of the Outstanding Shares.  Boston Safe Deposit and
Trust Company serves as the trustee of the CDCT No. 2.  Contran established the
CDCT No. 2 as an irrevocable "rabbi trust" to assist Contran in meeting certain
deferred compensation obligations that it owed to Harold C. Simmons.  If the
CDCT No. 2 assets are insufficient to satisfy such obligations, Contran is
obligated to satisfy the balance of such obligations as they come due.  Due to
the terms of the CDCT No. 2, Contran (i) retains the power to vote the shares of
Tremont and Valhi common stock held directly by the CDCT No. 2, (ii) retains
dispositive power over such shares and (iii) may be deemed the indirect
beneficial owner of such shares.  The foregoing summary of the CDCT NO. 2 is
qualified in its entirety by reference to Exhibit 6 to this Statement, which is
incorporated herein by this reference.

     The Combined Master Retirement Trust (the "CMRT") directly holds
approximately 0.1% of the Outstanding Shares.  The CMRT is a trust formed by the
Company to permit the collective investment by trusts that maintain the assets
of certain employee benefit plans adopted by the Company and related companies.
Mr. Simmons is the sole trustee of the CMRT and the sole 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.

     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 such entities and (b) Mr. Simmons and certain of such entities may be
deemed to possess indirect beneficial ownership of Shares directly held by
certain of such other entities.  However, Mr. Simmons disclaims such beneficial
ownership of the Shares beneficially owned, directly or indirectly, by any of
such entities, except to the extent of his vested beneficial interest in the
Shares held by the CMRT and his interest as a beneficiary of the CDCT No. 2.

     Harold C. Simmons' spouse is the direct beneficial owner of 77,000 Shares,
or approximately 0.1% of the Outstanding Shares.  Mr. Simmons may be deemed to
share indirect beneficial ownership of such Shares.  Mr. Simmons disclaims all
such beneficial ownership.

     The Reporting Persons understand that NL Industries, Inc. ("NL") and
Valmont Insurance Company ("Valmont") directly held 1,186,200 Shares and
1,000,000 Shares, respectively.  The Company and Tremont Corporation ("Tremont")
are the direct holders of approximately 58.3% and 17.7%, respectively, of the
outstanding common stock of NL and together may be deemed to control NL.  VGI,
National, the Harold Simmons Foundation, Inc. (the "Foundation"), the CDCT No.
2, the Company, NL and Valmont Insurance Company ("Valmont") are the direct
holders of approximately 35.1%, 5.2%, 3.7%, 3.5%, 1.5%, 0.5% and 0.5%,
respectively, of the outstanding common stock of Tremont.  Together, VGI and
National may be deemed to control Tremont.  The Company is the holder of 100% of
the outstanding common stock of Valmont and may be deemed to control Valmont.
Mr. Harold C. Simmons is chairman of the board of NL and is a director of
Tremont.

     Pursuant to two settlement agreements among the parties to Kahn v. Tremont
Corporation, et al. and Seinfeld v. Simmons, et al., respectively, the Company
has agreed to transfer a maximum of 1.4 million shares of NL common stock (2.7%
of the outstanding NL common stock) to Tremont and 825,000 shares of NL common
stock (1.6% of the outstanding NL common stock) to NL.  Each such number of
shares to be transferred may be adjusted downward to certain minimums subject to
the sales price per share of NL common stock on the day of closing.  The
settlements agreements are subject to the approval of the respective courts and
if approved are expected to close during the third quarter of 1998.

     The Reporting Persons further understand that, pursuant to Delaware law,
the Company treats the Shares that Valmont and NL hold directly as treasury
stock for voting purposes.  For the purposes of this Statement, the Shares that
Valmont and NL hold directly are not deemed outstanding.

     The Foundation is a tax-exempt foundation organized for charitable
purposes.  Harold C. Simmons is the chairman of the board and chief executive
officer of the Foundation and may be deemed to control the Foundation.  Mr.
Simmons, however, disclaims beneficial ownership of any Shares held by the
Foundation.

     (c)  The Company is a diversified holding company engaged, through
operating subsidiaries in the chemicals, component products and waste management
industries.

Item 3.   Source and Amount of Funds or Other Consideration

     No change except for the addition of the following:

     The total amount of funds required by Contran to acquire the Shares
reported in Item 5(c) was $670,025.00 (including commissions).  Such funds were
or will be provided by Contran's cash on hand and no funds were or will be
borrowed for such purpose.

Item 4.   Purpose of Transaction

     No change except for the addition of the following:

     The Reporting Persons acquired Shares to obtain an equity interest in and
control of the Company.  By virtue of the relationships and positions held by
Harold C. Simmons as reported in Item 2, Mr. Simmons, directly and indirectly
through Contran, may be deemed to control the Company.

     Contran purchased the additional Shares reported in Item 5(c) of this
Statement in order to increase its equity interest in the Company.  Depending
upon their evaluation of the Company's business and prospects, and upon future
developments (including, but not limited to, performance of the Shares in the
market, availability of funds, alternative uses of funds, and money, stock
market and general economic conditions), any of the Reporting Persons or other
entities that may be deemed to be affiliated with Contran may from time to time
purchase Shares, and any of the Reporting Persons or other entities that may be
deemed to be affiliated with Contran may from time to time dispose of all or a
portion of the Shares held by such person, or cease buying or selling Shares.
Any such additional purchases or sales of the Shares may be in open market or
privately negotiated transactions or otherwise.

     On February 6, 1998, Valhi, as lender, entered into a $120 million
revolving credit agreement with Contran, as borrower (the "Contran Credit
Agreement").  The Credit Agreement is effective on the date of the termination
of the Credit Agreement dated as of November 5, 1997 among Contran, National and
VGI, as borrowers, and United Sates National Bank of Oregon and Societe
Generale, Southwest Agency, as lenders, as such agreement has been amended by
(i) an Extension Agreement dated as of November 7, 1997 among the same parties
and (ii) a First Amendment to Loan Agreement dated as of January 9, 1998 among
the same parties (collectively, the "U.S. Bank/SoGen Facility").

     Contran intends to use the loan proceeds (i) to redeem shares of Contran's
outstanding stock from Contran stockholders that accept Contran's offer of
redemption pursuant to a settlement agreement arising from that certain civil
action styled In re:  The Harold C. Simmons Family Trust No. 1 (No. 96-306-P)
pending in the Probate Court of Dallas County, Texas (the "Settlement
Agreement") and (ii) for other general corporate purposes of the Borrower.  The
Settlement Agreement contemplates a dismissal with prejudice of all claims among
the parties to the litigation and no change to Harold C. Simmons' positions as
trustee of the Trusts or as a director and officer of the various businesses
owned directly and indirectly by the Trusts, including Contran and the Company.
In addition to the payment of legal fees from the Trusts, the Settlement
Agreement provides for the distribution by the Harold C. Simmons Family Trust
No. 2 of shares of Contran's Class A Common Stock, par value $0.01 per share
(the "Contran Class A Common Stock"), representing approximately 8.0% of the
outstanding Contran Class A Common Stock to two of Mr. Simmons' daughters and
certain trusts created for their benefit and the benefit of their descendants
together with the right to cause Contran to redeem such shares for consideration
of cash, notes and property the aggregate value of which is approximately $79.4
million.  The Settlement Agreement also provides that these two daughters will
surrender all of their rights in the Trusts.  Contran anticipates that the
distributees of the shares of Class A Common Stock will exercise their right of
redemption and these two daughters and their trusts will have no continuing
equity interest in Contran or any of its affiliates, including the Company.

     Borrowings under the Credit Agreement will bear interest at the prime rate
in effect from time to time  The maturity date under the Credit Agreement is
August 10, 1998.

     Contran's obligations under the Credit Agreement are secured by a pledge to
Valhi of (i) all of Contan's stock in Southwest (85.5% of Southwest's voting
stock), Dixie Rice (53.8% of Dixie Rice's voting stock), NOA (49.9% of NOA's
voting stock, the other 51.1% of which is directly owned by Southwest) and
National (85.7% of National's voting stock), all of which corporations in the
aggregate may be deemed to control, directly or indirectly, 84.7% of the
Outstanding Shares; and (ii) 7,958,958 Shares directly held by Contran (6.9% of
the Outstanding Shares).

     The Credit Agreement requires Contran to pay to the Company a commitment
fee in the amount of 1/2% per annum on the average daily unused and available
revolving credit commitment.  Contran may prepay borrowings under the Credit
Agreement at any time upon Contran's election.  In addition, Contran may at any
time upon notice to the Company terminate or reduce the unused amount of the
revolving credit commitment; provided, however, that any such termination or
reduction shall be permanent.

     Borrowings under the Credit Agreement are subject to numerous conditions,
including, among other things, the full execution and delivery of the Settlement
Agreement.  In addition, the Credit Agreement contains certain affirmative and
negative covenants of Contran, including restrictions on indebtedness and liens.

     The foregoing summary of the Credit Agreement is qualified in its entirety
by reference to Exhibit 7 to this Statement, which is incorporated herein by
this reference.

the Borrower substantially in the form of Exhibit A to this Agreement (the
"Note").

     1.4.  Limitations on and Continuance of Interest Rate.  

          (a)  Notwithstanding any of the other provisions of the Loan
     Documents, nothing contained in the Loan Documents shall require the
     Borrower to pay interest (including fees, charges, expenses or any other
     amounts that, under applicable law, are deemed interest) for the account of
     Lender or the holder of the Note at a rate exceeding the Maximum Lawful
     Rate.

          (b)  If the amount of any interest (including fees, charges or
     expenses or any other amounts that, under applicable law, are deemed
     interest) contracted for, charged or received by or for the account of
     Lender or the holder of the Note (the "Contract Rate") would exceed the
     Maximum Lawful Rate, then, ipso facto, the amount of such interest payable
     for the account of Lender or the holder of the Note in respect of such
     interest computation period shall be automatically reduced to such Maximum
     Lawful Rate, and if, from any such circumstance, Lender or the holder of
     the Note shall ever receive interest or anything that might be deemed
     interest under applicable law that would exceed the Maximum Lawful Rate,
     such amount that would be excessive shall be applied to the reduction of
     the principal amount owing on account of the Note or the amounts owing on
     other Obligations of the Borrower to Lender or the holder of the Note under
     any document executed in connection herewith and not to the payment of
     interest, or if such excessive interest exceeds the unpaid balance of
     principal of the Note and the amounts owing on other Obligations of the
     Borrower to Lender or the holder of the Note under any document executed in
     connection herewith, as the case may be, such excess shall be refunded to
     the Borrower.  All sums paid or agreed to be paid to Lender or the holder
     of the Note for the use, forbearance or detention of the Indebtedness of
     the Borrower to Lender or the holder of the Note shall, to the extent
     permitted by applicable law, be amortized, prorated, allocated and spread
     throughout the full term of such Indebtedness until payment in full of the
     principal (including the period of any renewal or extension thereof) so
     that the interest on account of such Indebtedness shall not exceed the
     Maximum Lawful Rate.

          (c)  If at any time the Contract Rate is limited to the Maximum Lawful
     Rate, any subsequent reductions in the Contract Rate shall not reduce the
     rate of interest on the Loan below the Maximum Lawful Rate until the total
     amount of interest accrued equals the amount of interest that would have
     accrued if the Contract Rate had at all times been in effect.  In the event
     that, upon demand or acceleration of the Note or at final payment of the
     Note, the total amount of interest paid or accrued on the Note is less than
     the amount of interest that would have accrued if the Contract Rate had at
     all times been in effect with respect thereto, then at such time, to the
     extent permitted by law, in addition to the principal and any other amounts
     Borrower owes Lender under the Loan Documents, the Borrower shall pay to
     the holder of the Note an amount equal to the difference between:  (i) the
     lesser of the amount of interest that would have accrued if the Contract
     Rate had at all times been in effect or the amount of interest that would
     have accrued if the Maximum Lawful Rate had at all times been in effect;
     and (ii) the amount of interest actually paid on such Note.

     1.5.  Payments; Optional Prepayments.  

          (a)  Interest accrued on the unpaid principal amount of the Loan shall
     be due and payable on the last Business Day of each calendar quarter and on
     the Maturity Date until the Loan is repaid in full.

          (b)  The principal amount of the Note and all accrued and unpaid
     interest shall be due and payable on August 10, 1998 (the "Maturity Date").
     Any principal amounts prepaid by the Borrower may be reborrowed at anytime
     upon notice prior to the Maturity Date up to the then current Revolving
     Credit Commitment subject to the conditions precedent in Section 2.

     1.6.  Form of Payments.  All payments (including prepayments) on account of
principal and interest shall be made in United States dollars and immediately
available funds.   If any payment is scheduled to become due and payable on a
day that is not a Business Day, such payment shall instead become due and
payable on the immediately following Business Day and such extension of time
shall be included in the computation of interest under the Loan Documents.

     1.7.  Use of Proceeds.  The proceeds of this Loan shall be used by the
Borrower: (i) to redeem shares of the Borrower's outstanding stock pursuant to a
settlement agreement arising from that certain civil action styled In re:  The
Harold C. Simmons Family Trust No. 1 (No. 96-306-P) pending in the Probate Court
of Dallas County, Texas (the "Settlement Agreement") and (ii) for other general
corporate purposes of the Borrower.

     1.8.  Limitation on Indebtedness.  The Borrower covenants and agrees that
so long as the Note remains unpaid or any of the Borrower's Obligations remain
unsatisfied under the Loan Documents, the Borrower will not incur, create,
assume, suffer to exist or in any manner become or be liable in respect of any
Indebtedness, liabilities or obligations, except for Permitted Indebtedness.

     1.9.  Limitation on Liens.  The Borrower covenants and agrees that so long
as the Note remains unpaid or any of the Borrower's Obligations remain
unsatisfied under the Loan Documents, the Borrower shall not create, assume,
incur or suffer to exist any Lien on or with respect to any of its property or
assets, whether now owned or hereafter acquired, or assign or otherwise convey
any right of the Borrower to receive income, except that the Borrower may
create, assume, incur or suffer to exist Permitted Liens.

     1.10.  Other Limitations.  The Borrower covenants and agrees during the
term of this Agreement:

          (a)  to preserve, renew and keep in full force and effect its
     corporate existence and rights with respect thereto and maintain in full
     force and effect all permits, licenses, trademarks, tradenames, approvals,

     presently or proposed to be conducted;

          (b)  to continue to conduct and operate its business and financial

     plans" (as those terms are defined by Section 3 of the Employee Retirement
     Income Security Act of 1974, as amended) to which such person is a party or
     sponsor in any material respect or any other material agreement,
     instrument, undertaking, or other contract to which such person is a party
     or by which its property is bound;

          (e)  not to (i) merge into or with or consolidate with any other
     Person or permit any other Person to merge into or with or consolidate with
     the Borrower unless Borrower is the surviving corporation or the surviving
     entity assumes the Obligations, (ii) sell, assign, lease or transfer
     (whether in one transaction or a series of transactions) to any Person all
     or substantially all of the Borrower's assets unless such Person assumes
     the Obligations, (iii) wind up, liquidate or dissolve or (iv) agree to do
     any of the foregoing;

          (f)  to pay and discharge all taxes, assessments and governmental and
     other charges and claims levied or imposed on or that, if unpaid when due,
     might become a Lien upon its assets, earnings or business; except such
     taxes as are being contested in good faith and against which adequate
     reserves have been provided in accordance with GAAP;

          (g)  (i) to maintain insurance with responsible and reputable

     reasonably be expected to cause a material adverse effect on the financial
     condition or operations of the Borrower taken as a whole and (ii) to
     maintain such other insurance as may be required by law; provided that the
     Borrower may self-insure to the extent and in the manner normal for
     similarly situated companies of like size, type and financial condition
     that are part of a group of companies under common control;

          (h)  The Borrower will comply at all times in all material respects

SECTION 3.  REPRESENTATIONS AND WARRANTIES.

     3.1.  Representations and Warranties of the Borrower.  In order to induce
Lender to enter into the Loan Documents to which it is a party and to make the
Loan, the Borrower represents and warrants on the Effective Date and on the date
of each subsequent Revolving Credit Advance to the following.

          (a)  Existence, Power and Authority.  The Borrower is a corporation
     duly incorporated, validly existing and in good standing under the laws of
     the state of Delaware with full power and authority to carry on its
     business as presently conducted and as proposed to be conducted by it and
     to own or hold under lease its properties.  The Borrower has full power and
     authority to execute and deliver the Loan Documents to which it is a party
     and to perform its obligations and carry out the transactions so
     contemplated.

          (b)  Borrower Authorization; Enforceable Obligations.  The Loan
     Documents to which the Borrower is a party have been duly authorized,
     executed and delivered by the Borrower and constitute legal, valid and
     binding obligations of the Borrower, enforceable against the Borrower in
     accordance with their respective terms (except to the extent that
     enforcement may be limited by any applicable bankruptcy, reorganization,
     moratorium or similar laws now or subsequently in effect, which may affect
     the enforceability of creditors' rights generally, or by general equitable
     principles).

          (c)  No Legal Bar.  The execution, delivery and performance of the
     Loan Documents, the borrowings by the Borrower hereunder, the use of
     proceeds thereof and the grant of security interests in the Pledged
     Collateral (i) are not and will not be in violation of the Borrower's
     charter or bylaws as they exist at such time; (ii) are not and will not be
     in violation of or conflict with any valid law or governmental rule or
     regulation, judgment, writ, order, injunction, award or decree of any
     court, arbitrator, administrative agency or other governmental authority
     applicable to the Borrower; or (iii) are not and will not conflict or be
     inconsistent with, or result in any breach of, any of the terms, covenants,
     conditions or provisions of or constitute a default under any material
     indenture, mortgage, contract, deed of trust, debenture, agreement or other
     undertaking or instrument to which the Borrower is a party or by which any
     of its material assets may be bound or affected; except where the
     violation, conflict, inconsistency, breach or default would not have a
     material adverse effect on the financial condition or operations of the
     Borrower taken as a whole or on its ability to repay the Loan.  The
     execution, delivery and performance of the Loan Documents do not and will
     not result in the creation or imposition of any material Lien on the
     Borrower's assets pursuant to the provisions of any such indenture,
     mortgage, contract, deed of trust, debenture, agreement or other
     undertaking or instrument (other than the security interest on the Pledged
     Collateral granted by Borrower pursuant to Section 4 of this Agreement).

          (d)  No Debt Restrictions.  No material note, bond, debenture,
     indenture, mortgage, contract, deed of trust, agreement or other
     undertaking or instrument to which the Borrower is subject contains any
     restriction on the incurrence by the Borrower of Indebtedness under the
     Loan Documents, except such restrictions as have been waived in writing
     (copies of which shall be furnished to Lender).

          (e)  No Consents.  No material permit, consent, approval or
     authorization of, or declaration to or filing with, any governmental
     authority is required in connection with the execution, delivery and
     performance of the Loan Documents.

          (f)  Financial Condition.  The annual and interim financial statements
     of the Borrower furnished to the Lender present fairly the financial
     position of Borrower as of the date of such financial statements and the
     results of the operations and changes in financial position for the annual
     and interim periods then ending.

          (g)  Litigation.  There are no actions, suits or proceedings pending
     against the Borrower at law, in equity or in admiralty or by or before any
     governmental authority, and, to the best knowledge of the Borrower, there
     are no actions, suits or proceedings threatened against the Borrower,
     except for such actions, suits or proceedings that could not reasonably be
     expected to cause a material adverse effect on the financial condition or
     operations of the Borrower taken as a whole.

          (h)  Title to Collateral; Liens.  The Borrower has good and
     indefeasible title to all Pledged Collateral. Except for Permitted Liens,
     all of the Pledged Collateral is free and clear of any and all Liens.

          (i)  Tax Returns.  Except as previously disclosed to the Lender and
     except in connection with taxes being diligently contested in good faith
     and for which reserves in accordance with GAAP are maintained, the Borrower
     has filed or caused to be filed all tax returns (or extensions) that it was
     required to file, paid and discharged or caused to be paid and discharged
     all taxes as shown on such returns (or extensions) or on any assessment
     received by it to the extent that such taxes have become due, and does not
     know of any actual or proposed assessments for additional governmental or
     other taxes for any fiscal period.  The charges, accruals and reserves on
     its respective books with respect to governmental and other taxes for all
     fiscal periods are adequate.

          (j)  Compliance with Law.  The Borrower is in compliance in all
     material respects with all statutory laws, regulations, and orders that are
     applicable to it and its property specifically including, but not limited
     to, environmental laws.

          (k)  Hazardous Material.  To the best knowledge of the Borrower, there
     is no hazardous material being released, and no hazardous material has been
     released, from or at any real property owned or operated by the Borrower
     the liability for which could reasonably be expected to cause a material
     adverse effect on the financial condition or operations of the Borrower
     taken as a whole, except as disclosed to the Lender.

          (l)  No Material Adverse Change.  There has been no material adverse
     change in the business operations, financial position or cash flows of the
     Borrower since the date of the latest financial statements provided to the
     Lender.

          (m)  Not an Investment Company.  The Borrower is not an "investment
     company" or a company "controlled" by an "investment company" within the
     meaning  of the Investment Company Act of 1940, as amended.

          (n)  Use of Proceeds.  The Borrower is not engaged principally, or as
     one of its important activities, in the business of extending credit for
     the purpose of purchasing or carrying margin stock within the meaning of
     Regulation U or X of the Board of Governors of the Federal Reserve System.
     No proceeds of any Revolving Credit Advance will be used to purchase or
     carry any margin stock in violation of Regulations G, T, U or X of the
     Board of Governors of the Federal Reserve System.

          (o)  Solvency.  The Borrower is solvent and is not the subject of any
     insolvency proceedings and the Borrower has capital that is reasonably
     adequate to conduct its business in the manner in which it intends to
     conduct such business.

          (p)  No Misleading Statements.  The representations of the Borrower in
     this Agreement or in any exhibit, annex, schedule, list or other document
     delivered to Lender in connection with the transactions contemplated by the
     Loan Documents do not contain any untrue statement of a material fact or
     omit to state a material fact necessary in order to make the statements
     contained therein or herein not misleading.

     3.2.  Representations and Warranties of Lender.  Lender hereby represents
and warrants on the Effective Date to the following.

          (a)  Existence, Power and Authority.  Lender is a corporation duly
     incorporated and validly existing, in good standing, under the laws of
     Delaware with full power, authority and legal right to execute and deliver
     the Loan Documents to which Lender is a party and to carry out the
     transactions so contemplated.

          (b)  Lender Authorization; Enforceable Obligations.  The Loan
     Documents to which the Lender is a party have been duly authorized,
     executed and delivered by the Lender and constitute legal, valid and
     binding obligations of the Lender, enforceable against the Lender in
     accordance with their respective terms (except to the extent that
     enforcement may be limited by any applicable bankruptcy, reorganization,
     moratorium or similar laws now or subsequently in effect, which may affect
     the enforceability of creditors' rights generally, or by general equitable
     principles).

          (c)  No Legal Bar.  The execution, delivery and performance of the
     Loan Documents and the making of the Loan by Lender (i) are not and will
     not be in violation of the Lender's charter or bylaws as they exist at such
     time; (ii) are not and will not be in violation of or conflict with any
     valid law or governmental rule or regulation, judgment, writ, order,
     injunction, award or decree of any court, arbitrator, administrative agency
     or other governmental authority applicable to the Lender; or (iii) are not
     and will not conflict or be inconsistent with, or result in any breach of,
     any of the terms, covenants, conditions or provisions of or constitute a
     default under any material indenture, mortgage, contract, deed of trust,
     debenture, agreement or other undertaking or instrument to which the Lender
     is a party or by which any of its material assets may be bound or affected;
     except where the violation, conflict, inconsistency, breach or default
     would not have a material adverse effect on the financial condition or
     operations of the Lender taken as a whole or the ability of Lender to make
     the Loan.

          (d)  No Consents.  No material authorization or approval of any public
     regulatory body is required in connection with the execution, delivery or
     performance by Lender of the Loan Documents to which it is a party.

SECTION 4.  GRANT OF SECURITY INTEREST.

4.1.  Grant of Security Interest.  To secure payment and performance of all
Obligations, Borrower hereby grants to Lender a continuing security interest in,
a Lien upon, and a right of set off against, and hereby assigns to Lender as
security, the Pledged Collateral as more fully described in the Borrower Pledge.
SECTION 5.  EVENTS OF DEFAULT.

     5.1.  Events of Default.  For the purposes of this Agreement, an event of
default (an ("Event of Default") will be deemed to have occurred if:

          (a)  the Borrower fails pay principal when due (whether at maturity,
     by acceleration or otherwise) on the Note or Borrower fails to pay
     interest, any fee or any other amount on the Loan Documents and such
     default continues for a period of three (3) Business Days after any such
     payment becomes due and payable (a "Monetary Default");

          (b)  the Borrower breaches or otherwise fails to perform or observe

omission or event occurring in connection herewith, unless it is determined by a
final and non-appealable judgment or court order binding on Lender, that the
losses were the result of acts or omissions constituting gross negligence or
willful misconduct.  In any such litigation, Lender shall be entitled to the
benefit of the rebuttable presumption that it acted in good faith and with the
exercise of ordinary care in the performance by it of the terms of the Loan
Documents.

harmless set forth in this Section may be unenforceable because it violates any

matters under this Section.  The foregoing indemnity shall survive the payment
of the Obligations and the termination or non-renewal of the Loan Documents.

     6.4.  Authority of Lender.  Lender shall have and be entitled to exercise
all powers under the Loan Documents that are specifically granted to Lender by
the terms thereof, together with such powers as are reasonably incident thereto.
Lender may perform any of its duties hereunder or in connection with the Loan
Documents or the Pledged Collateral by or through agents or employees and shall

concerning all such matters.  Neither Lender nor any director, officer,
employee, attorney or agent of Lender shall be liable to Borrower for any action
taken or omitted to be taken by it or them under the Loan Documents, except for
its or their own gross negligence or willful misconduct, nor shall Lender be
responsible for the validity, effectiveness or sufficiency of the Loan Documents
or any security furnished pursuant thereto.  Lender and its directors, officers,
employees, attorneys and agents shall be entitled to rely on any communication,
instrument or document reasonably believed by it or them to be genuine and
correct and to have been signed or sent by the proper person or persons.

     6.5.  Amendments and Waivers.  None of the Loan Documents nor any provision
thereof shall be amended, modified, waived or discharged orally or by course of
conduct, but only by a written agreement signed by an authorized officer of
Lender.  Lender shall not, by any act, delay, omission or otherwise be deemed to
have expressly or impliedly waived any of its rights, powers and/or remedies
unless such waiver shall be in writing and signed by an authorized officer of
Lender.  Any such waiver shall be enforceable only to the extent specifically
set forth therein.  A waiver by Lender of any right, power and/or remedy on any
one occasion shall not be construed as a bar to or waiver of any such right,
power and/or remedy that Lender would otherwise have on any future occasion,
whether similar in kind or otherwise.

     6.6.  Cumulative Remedies.  The rights and remedies provided in the Loan
Documents are cumulative and not exclusive of any rights or remedies provided by
law.

     6.7.  Survival of Provisions.  All representations, warranties and
covenants made in the Loan Documents shall survive the execution and delivery of
the Loan Documents and the making of the Loan.  Such representations, warranties
and covenants shall terminate only upon the full and final payment and
performance by the Borrower of the Obligations and termination of this Agreement
and the Note.

     6.8.  Term of Agreement.  This Agreement shall continue until the Note has
been paid in full or discharged in accordance with the terms of this Agreement
and until all Obligations of the Borrower under the Loan Documents shall have
been fully satisfied.

     6.9.  Reinstatement.  To the extent permitted by law, the Loan Documents
shall continue to be effective or be reinstated, as the case may be, if at any
time any amount received by Lender, in respect of the Obligations is rescinded
or must otherwise be restored or returned by Lender, upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of Borrower or upon the
appointment of any receiver, intervenor, conservator, trustee or similar
official for Borrower or any substantial part of its assets, or otherwise, all
as though such payments had not been made.

     6.10.  Governing Law.  The validity, interpretation and enforcement of the
Loan Documents and any dispute arising out of the relationship between the
parties thereto, whether in contract, tort, equity or otherwise, shall be
governed by the internal laws of the state of Texas (without giving effect to
principles of conflicts of law).  Pursuant to Article 15.10(b) of Chapter 15
("Chapter 15") of the Texas Credit Code, the parties hereto expressly agree that
Chapter 15 shall not apply to the Loan Documents or to any advance, nor shall
the Loan Documents or any Revolving Credit Advance be governed by or be subject
to the provisions of Chapter 15 in any manner whatsoever.

     6.11.  Choice of Forum.  Borrower and Lender irrevocably consent and submit
to the non-exclusive jurisdiction of the courts of the state of Texas located in
Dallas, Texas and the United States District Court for the Northern District of
Texas and waive any objection based on venue or forum non conveniens with
respect to any action instituted therein arising under the Loan Documents or in
any way connected with or related or incidental to the dealings of the parties
hereto with respect to the Loan Documents or the transactions related thereto,
in each case whether now existing or hereafter arising, and whether in contract,
tort, equity or otherwise, and agree that any dispute with respect to any such
matters shall be heard only in the courts described above (except that Lender
shall have the right to bring any action or proceeding against Borrower or its
property in the courts of any other jurisdiction that Lender deems necessary or
appropriate in order to realize on the Pledged Collateral or to otherwise
enforce its rights against Borrower or its property).

     6.12.  Successors and Assigns.  Loan Documents shall be binding upon and
inure to the benefit of and be enforceable by Lender, Borrower and their
respective successors and permitted assigns, except that Borrower may not assign
its rights under this Agreement without the prior written consent of
Lender.  Lender may assign its rights and delegate its obligations under the
Loan Documents to another Person, in which event, the assignee or participant
shall have, to the extent of such assignment or participation, the same rights
and benefits as it would have if it were the Lender hereunder, except as
otherwise provided by the terms of such assignment or participation.

     6.13.  No Third-Party Rights.  The Loan Documents are not intended to and
shall not be construed to create any rights in or confer any benefits on any
persons other than the parties thereto and their respective successors and
permitted assigns.

     6.14.  Complete Agreement.  The Loan Documents represent the final
agreement between the parties and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties.  There are no
unwritten oral agreements between the parties.

     6.15.  Partial Invalidity.  If any provision of the Loan Documents is held
to be invalid or unenforceable, such invalidity or unenforceability shall not
invalidate the Loan Documents as a whole, but the Loan Documents shall be
construed as though they did not contain the particular provision held to be
invalid or unenforceable and the rights and obligations of the parties shall be
construed and enforced only to such extent as shall be permitted by applicable
law.

     6.16.  Interpretation of Agreement.  Time is of the essence in each
provision of the Loan Documents of which time is an element.  All terms not
defined herein or in the Loan Documents shall have the meaning set forth in the
applicable Uniform Commercial Code, except where the context otherwise requires.
Acceptance of or acquiescence in a course of performance rendered under the Loan
Documents shall not be relevant in determining the meaning of the Loan Documents
even though the accepting or acquiescing party had knowledge of the nature of
the performance and opportunity for objection.

     6.17.  Conflicts.  The terms and conditions of the Loan Documents are
intended to complement and supplement each other and are to be construed so as
to be consistent and complimentary.  In the event that a conflict of terms
cannot be reconciled, the terms and conditions of this Agreement will govern
over any conflicting terms or conditions in any other Loan Document.

     6.18.  Waiver of Notices.  Borrower hereby expressly waives demand,
presentment, protest and notice of protest and notice of dishonor with respect
to any and all instruments and commercial paper, included in or evidencing any
of the Obligations or the Pledged Collateral, and any and all other demands and
notices of any kind or nature whatsoever with respect to the Obligations, the
Pledged Collateral and the Loan Documents, except such as are expressly provided
for in the Loan Documents.  No notice to or demand on Borrower that Lender may
elect to give shall entitle Borrower to any other or further notice or demand in
the same, similar or other circumstances.

     6.19.  Notices.  All notices, demands or other communications to be given
or delivered under or by reason of this Agreement shall be in writing (including

                                Steven L. Watson, Vice President

                                   EXHIBIT B

                               PLEDGE AGREEMENT

     THIS PLEDGE AGREEMENT (this "Agreement") is made and entered into as of
February __, 1998, by CONTRAN CORPORATION, a Delaware corporation ("Pledgor"),
in favor of VALHI, INC., a Delaware corporation ("Lender").

                                    Recitals

     A.   Pledgor is the owner of the outstanding shares (the "Pledged
Interests") set forth on Schedule I hereto of its subsidiaries (the "Issuers").

     B.   Pledgor has entered into a credit facility with Lender for the
purposes described in the Credit Agreement effective as of the date of this
Agreement, between Pledgor and Lender (as the same has been or may from time to
time be amended, restated, supplemented or otherwise modified, the "Credit
Agreement").

     C.   Lender has required, as a condition to its entering into the Credit
Agreement, that Pledgor (i) pledge to Lender, and grant to Lender a security
interest in, the Pledged Collateral (as defined in Section 1) and (ii) execute
and deliver this Agreement in order to secure the payment and performance by
Pledgor of the Obligations.

     D.   Capitalized terms used in this Agreement and not otherwise defined
shall have the meanings given to such terms in the Credit Agreement.

                                   Agreement

     In consideration of the premises and in order to induce Lender to extend
credit under the Loan Documents to Pledgor, Pledgor hereby agrees with Lender as
follows.

     SECTION 1.  PLEDGE.   Pledgor hereby pledges and collaterally assigns to
Lender, and grants to Lender a continuing first priority and perfected security
interest in the following (the "Pledged Collateral"):

          (a)  the Pledged Interests and the certificates representing the
     Pledged Interests, and all products and proceeds of any of the Pledged
     Interests including, without limitation, all distributions, cash,
     instruments, subscriptions, warrants and any other rights and options and
     other property from time to time received, receivable or otherwise
     distributed in respect of or in exchange for any or all of the Pledged
     Interests; and

          (b)  any other securities or interests that Pledgor is required to
     pledge to Lender at any time pursuant to the Credit Agreement, the
     certificates representing such securities, and all products and proceeds of
     any of such securities, including, without limitation, all distributions,
     cash, instruments, subscriptions, warrants and any other rights and options
     and other property from time to time received, receivable or otherwise
     distributed in respect of or in exchange for any or all of such securities.

     SECTION 2.  SECURITY FOR OBLIGATIONS.  This Agreement secures the payment
of all of the Obligations.

     SECTION 3.  DELIVERY OF PLEDGED COLLATERAL.  All certificates or
instruments representing or evidencing the Pledged Collateral shall be delivered
to and held by or on behalf of Lender and shall be in suitable form for transfer
by delivery, or shall be accompanied by duly executed instruments of transfer or
assignment in blank, all in form and substance reasonably satisfactory to
Lender.

     SECTION 4.  REPRESENTATIONS AND WARRANTIES.  Pledgor represents and
warrants with respect to the Pledged Interests as of the date hereof and with
respect to the Pledged Interests and any other securities pledged to Lender
pursuant to the Credit Agreement as of the date of such later pledge, the
following.

          (a)  Pledgor is the legal and beneficial owner of the Pledged
     Collateral, free and clear of any Lien.

          (b)  To the knowledge of the Pledgor, the issuers of the Pledged
     Interests duly authorized the issuance of such Pledged Interests and the
     Pledged Interests are validly issued, fully paid and nonassessable.

          (c)  The pledge and collateral assignment of the Pledged Collateral
     pursuant to this Agreement creates a valid and perfected first priority
     security interest in such Pledged Collateral securing the payment of the
     Obligations for the benefit of Lender.

          (d)  On the Effective Date, no authorization, approval, or other
     action by, and no notice to or filing with, any governmental authority or
     regulatory body is required either (i) for the pledge and collateral
     assignment by Pledgor of the Pledged Collateral pursuant to this Agreement
     or for the execution, delivery or performance of this Agreement by Pledgor
     or (ii) for the exercise by Lender of the voting or other rights provided
     for in this Agreement or the remedies in respect of the Pledged Collateral
     pursuant to this Agreement (except such filings of beneficial ownership as
     may be required by federal securities laws).

          (e)  Pledgor has full power and authority to enter into the Loan
     Documents, has the right to vote all securities that have voting power and
     are pledged hereunder and to pledge, collaterally assign and grant a
     security interest in the Pledged Collateral.

          (f)  The Loan Documents have been duly authorized, executed and
     delivered by Pledgor and constitute legal, valid and binding obligations of
     Pledgor, enforceable against Pledgor in accordance with their respective
     terms, except as such enforceability may be limited by the effect of any
     applicable bankruptcy, insolvency, reorganization, moratorium or other
     similar laws affecting creditors' rights generally or general principles of
     equity.

          (g)  To the best of Pledgor's knowledge, the Pledged Interests
     constitute, as of the date hereof, the percentage of the authorized, issued
     and outstanding share of common stock of the Issuer(s) set forth on
     Schedule I hereto.

          (h)  Pledgor's chief executive office is located at the address set
     forth in Section 15(u).

     SECTION 5.  FURTHER ASSURANCES; COVENANTS.  Pledgor agrees that at any time
and from time to time, at the expense of Pledgor, Pledgor will promptly execute
and deliver, or cause to be executed and delivered, all powers, proxies,
assignments, instruments and documents and take all further action, that is
reasonably necessary to perfect any security interest granted or purported to be
granted hereby or to enable Lender to exercise and enforce its rights and
remedies hereunder with respect to any Pledged Collateral and to carry out the
provisions and purposes hereof

     SECTION 6.  VOTING RIGHTS; DISTRIBUTIONS; ETC.

          (a)  So long as no Event of Default shall have occurred and be
     continuing, Pledgor shall be entitled to exercise any and all voting and
     other consensual rights pertaining to securities pledged hereunder or any
     part thereof for any purpose not inconsistent with the terms of this
     Agreement.

          (b)  So long as no Event of Default shall have occurred and be
     continuing, Pledgor shall be entitled to receive all regular quarterly cash
     distributions.  All other distributions paid or made from time to time with
     respect to the securities pledged hereunder shall be delivered to the
     Lender pursuant to Section 3.  Upon the occurrence and during the
     continuance of an Event of Default, all rights of Pledgor to exercise the
     voting and other consensual rights that it would otherwise be entitled to
     exercise pursuant to Section 6(a) shall cease, and all such rights shall
     become vested in Lender, which shall thereupon have the sole right to
     exercise such voting and other consensual rights.  Upon the occurrence and
     during the continuance of an Event of Default, all distributions payable in
     respect of all securities pledged hereunder shall be paid directly to
     Lender and, if received by Pledgor, shall be received in trust for the
     benefit of Lender, shall be segregated from other funds of Pledgor, and
     shall be forthwith transferred or paid over to Lender as Pledged Collateral
     in the same form as so received (with any necessary endorsements) and
     Pledgor's right to receive such distributions.

     SECTION 7.  TRANSFERS AND OTHER LIENS.  Pledgor agrees that it will not (i)
sell or otherwise dispose of, or grant any option with respect to, any of the
Pledged Collateral without the prior written consent of Lender, (ii) create or
permit to exist any Lien or encumbrance upon or with respect to any of the
Pledged Collateral, except for the security interest granted under this
Agreement or (iii) enter into any agreement or understanding that purports to or
may restrict or inhibit Lender's rights or remedies hereunder, including,
without limitation, Lender's right to sell or otherwise dispose of the Pledged
Collateral.

     SECTION 8.  LENDER APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby appoints
Lender as Pledgor's attorney-in-fact, with full authority in the place and stead
of Pledgor and in the name of Pledgor or otherwise, from time to time in
Lender's discretion to take any action and to execute any instrument that Lender
may deem necessary or advisable to further perfect and protect the security
interest granted hereby, including, without limitation, to receive, endorse and
collect all instruments made payable to Pledgor representing any distribution in
respect of the Pledged Collateral or any part thereof and to give full discharge
for the same.

     SECTION 9.  LENDER MAY PERFORM.  If Pledgor fails to perform any agreement
contained herein, Lender may itself perform, or cause performance of, such
agreement, and the reasonable expenses of Lender incurred in connection
therewith shall be payable by Pledgor under Section 13.

     SECTION 10.  NO ASSUMPTION OF DUTIES; REASONABLE CARE.  The rights and
powers granted to Lender under this Agreement are being granted in order to
preserve and protect Lender's security interest in and to the Pledged Collateral
and shall not be interpreted to, and shall not, impose any duties on Lender in
connection therewith.  Lender shall be deemed to have exercised reasonable care
in the custody and preservation of the Pledged Collateral in its possession if
the Pledged Collateral is accorded treatment substantially equal to that which
Lender accords its own property, it being understood that Lender shall not have
any responsibility for (i) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relative to any
Pledged Collateral, whether or not Lender has or is deemed to have knowledge of
such matters, or (ii) taking any necessary steps to preserve rights against any
parties with respect to any Pledged Collateral.

     SECTION 11.  SUBSEQUENT CHANGES AFFECTING PLEDGED COLLATERAL.  Pledgor
represents to Lender that Pledgor has made its own arrangements for keeping
informed of changes or potential changes affecting the Pledged Collateral
(including, but not limited to, rights to convert, rights to subscribe, payment
of dividends, payments of interest and/or principal, reorganization or other
exchanges, tender offers and voting rights), and Pledgor agrees that Lender
shall have no responsibility or liability for informing Pledgor of any such
changes or potential changes or for taking any action or omitting to take any
action with respect thereto.

     SECTION 12.  REMEDIES UPON DEFAULT.  In addition to the rights of Lender
pursuant to Section 6, if any Event of Default shall have occurred and be
continuing, Lender shall, in addition to all other rights given by law or by
this Agreement, or otherwise, have all of the rights and remedies with respect
to the Pledged Collateral of a secured party under the Uniform Commercial Code
("Code") in effect in the State of Texas at that time and Lender may, without
notice and at its option, transfer or register, and Pledgor shall register or
cause to be registered upon request therefor by Lender, any securities pledged
hereunder or any part thereof on the books of the issuer thereof into the name
of Lender or Lender's nominee(s), indicating that such securities are subject to
the security interest under the Credit Agreement.  In addition, with respect to
any Pledged Collateral that shall then be in or shall thereafter come into the
possession or custody of Lender, Lender may sell or cause the same to be sold at
any broker's board or at any public or private sale, in one or more sales or
lots, at such price or prices as Lender may deem best, for cash or on credit or
for future delivery, without assumption of any credit risk, all in accordance
with the terms and provisions of this Agreement.  The purchaser of any or all
Pledged Collateral so sold shall thereafter hold the same absolutely, free from
any claim, encumbrance or right of any kind whatsoever.  Unless any of the
Pledged Collateral threatens to decline speedily in value or is or becomes of a
type sold on a recognized market, Lender will give Pledgor reasonable notice of
the time and place of any public sale thereof, or of the time after which any
private sale or other intended disposition is to be made.  Any sale of the
Pledged Collateral pursuant to this Agreement conducted in conformity with
reasonable commercial practices of banks, insurance companies, commercial
finance companies, or other financial institutions disposing of property similar
to the Pledged Collateral shall be deemed to be commercially reasonable.  Any
requirements of reasonable notice shall be met if such notice is mailed to
Pledgor as provided in Section 15(u) below, at least five (5) days before the
time of the sale or disposition.  Pledgor waives any other requirement of
notice, demand or advertisement for sale, to the extent permitted by law.
Lender may, in its own name or in the name of a designee or nominee, buy any of
the Pledged Collateral at any public sale and, if permitted by applicable law,
at any private sale.  All expenses (including court costs and reasonable
attorneys' fees, expenses and disbursements) of, or incident to, the enforcement
of any of the provisions of this Agreement shall be recoverable from the
proceeds of the sale or other disposition of the Pledged Collateral.  In view of
the fact that federal and state securities laws may impose certain restrictions
on the method by which a sale of the Pledged Collateral may be effected after an
Event of Default, Pledgor agrees that upon the occurrence or existence of any
Event of Default, Lender may, from time to time, attempt to sell all or any part
of the Pledged Collateral pursuant to this Agreement or by means of a private
placement, restricting the prospective purchasers to those who will represent
and agree that they are purchasing for investment only and not for distribution.
In so doing, Lender may solicit offers to buy the Pledged Collateral, or any
part of it, for cash, from a limited number of investors who might be interested
in purchasing the Pledged Collateral, and if Lender solicits such offers from
not less than four (4) such investors that are not affiliated with Lender, then
the acceptance by Lender of the highest offer obtained therefrom shall be deemed
to be a commercially reasonable method of disposition of the Pledged Collateral,
and a sale pursuant to this sentence shall be deemed to be a commercially
reasonably disposition of the Pledged Collateral.

     SECTION 13.  EXPENSES.  Pledgor will pay to Lender the amount of any and
all reasonable out-of-pocket expenses, including, without limitation, the
reasonable fees, expenses and disbursements of its counsel (including allocated
costs of inside counsel), of any investment banking firm, business broker or
other selling agent and of any other experts and agents retained by Lender,
which Lender may incur in connection with (i) the administration of this
Agreement and the Credit Agreement, (ii) the custody or preservation of, or the
sale of, collection from, or other realization upon, any of the Pledged
Collateral, (iii) the exercise or enforcement of any of the rights of Lender
hereunder or under the Credit Agreement or (iv) the failure by Pledgor to
perform or observe any of the provisions hereof or of the Credit Agreement.  All
amounts owing under this Section shall be payable upon demand.  Any and all
amounts payable under or pursuant to this Agreement that are not paid when due
shall bear interest (which shall be payable upon demand) at the Prime Rate plus
2% per annum.

     SECTION 14.  SECURITY INTEREST ABSOLUTE.  All rights of Lender and security
interests under this Agreement, and all obligations of Pledgor under this
Agreement, shall be absolute and unconditional irrespective of, and unaffected
by:

          (a)  any lack of validity or enforceability of this Agreement, the
     Credit Agreement or the Note;

          (b)  any change in the time, manner or place of payment of, or in any
     other term of, all or any of the Obligations, or any other amendment or
     waiver of or any consent to any departure from the Loan Documents; or

          (c)  any other circumstance that might otherwise constitute a defense
     available to, or a discharge of, Pledgor in respect of the Obligations or
     of this Agreement.

     SECTION 15.  MISCELLANEOUS PROVISIONS.

          (a)  Continuing Security Interest.  This Agreement shall create a
     continuing security interest in the Pledged Collateral and shall remain in
     full force and effect until the termination of this Agreement pursuant to
     Section 15(b).

          (b)  Release; Termination of Agreement.  At any time following the
     termination of the Loan Documents shall upon written request to Lender, be
     terminated; provided, however, if at any time following any such
     termination, the Credit Agreement is reinstated, this Agreement shall be
     automatically reinstated and shall thereafter continue in full force and
     effect.  Upon termination of this Agreement, Lender shall, at the request
     and expense of Pledgor, reassign and redeliver to Pledgor all of the
     Pledged Collateral hereunder that has not been sold, disposed of, retained
     or applied by Lender in accordance with the terms hereof.  Such
     reassignment and redelivery shall be without warranty by or recourse to
     Lender, except as to the absence of any prior assignments by Lender of its
     interest in the Pledged Collateral, and shall be at the expense of Pledgor.

          (c)  Foreclosure Waiver.  Lender and Pledgor waive all rights of
     notice and hearing of any kind prior to the exercise by Lender of its
     rights from and after an Event of Default to repossess with judicial
     process any of the Pledged Collateral not in Pledgor's possession or to
     replevy, attach or levy upon the Pledged Collateral.  Pledgor waives the
     posting of any bond otherwise required of Lender in connection with any
     judicial process or proceeding to obtain possession of, replevy, attach or
     levy upon pledged collateral, to enforce any judgment or other security for
     the Obligations, to enforce any judgment or other court order entered in
     favor of such party or to enforce by specific performance, temporary
     restraining order, preliminary or permanent injunction, this agreement, or
     any other agreement or document between Pledgor and any such party.

          (d)  Limitation of Liability.  Lender shall not have any liability to
     Pledgor (whether in tort, contract, equity or otherwise) for losses
     suffered by Pledgor in connection with, arising out of, or in any way
     related to the transactions or relationships contemplated by the Loan
     Documents, or any act, omission or event occurring in connection herewith,
     unless it is determined by a final and non-appealable judgment or court
     order binding on Lender, that the losses were the result of acts or
     omissions constituting gross negligence or willful misconduct.  In any such
     litigation, Lender shall be entitled to the benefit of the rebuttable
     presumption that it acted in good faith and with the exercise of ordinary
     care in the performance by it of the terms of the Loan Documents.

          (e)  Indemnity.  Pledgor shall indemnify and hold Lender, and its
     directors, agents, employees and counsel, harmless from and against any and
     all losses, claims, damages, liabilities, costs or expenses ("Indemnified
     Amounts") imposed on, incurred by or asserted against any of them in
     connection with any litigation, investigation, claim or proceeding
     commenced or threatened related to the negotiation, preparation, execution,
     delivery, enforcement, performance or administration of the Loan Documents,
     or any undertaking or proceeding related to any of the transactions
     contemplated by such or any act, omission, event or transaction related or
     attendant thereto, including, without limitation, amounts paid in
     settlement, court costs, and the reasonable out-of-pocket fees and expenses
     of counsel, unless the Indemnified Amounts proximately result from the
     gross negligence or willful misconduct of Lender or the intentional breach
     by Lender of any obligation of Lender under the Loan Documents.  To the
     extent that the undertaking to indemnify, pay and hold harmless set forth
     in this Section may be unenforceable because it violates any law or public
     policy, Pledgor shall pay the maximum portion that it is permitted to pay
     under applicable law to Lender in satisfaction of indemnified matters under
     this Section.  The foregoing indemnity shall survive the payment of the
     Obligations and the termination or non-renewal of the Loan Documents.

          (f)  Authority of Lender.  Lender shall have and be entitled to
     exercise all powers under the Loan Documents that are specifically granted
     to Lender by the terms thereof, together with such powers as are reasonably
     incident thereto.  Lender may perform any of its duties hereunder or in
     connection with the Loan Documents or the Pledged Collateral by or through
     agents or employees and shall be entitled to retain counsel and to act in
     reliance upon the advice of counsel concerning all such matters.  Neither
     Lender nor any director, officer, employee, attorney or agent of Lender
     shall be liable to Pledgor for any action taken or omitted to be taken by
     it or them under the Loan Documents, except for its or their own gross
     negligence or willful misconduct, nor shall Lender be responsible for the
     validity, effectiveness or sufficiency of the Loan Documents or any
     security furnished pursuant thereto.  Lender and its directors, officers,
     employees, attorneys and agents shall be entitled to rely on any
     communication, instrument or document reasonably believed by it or them to
     be genuine and correct and to have been signed or sent by the proper person
     or persons.

          (g)  Amendments and Waivers.  None of the Loan Documents nor any
     provision thereof shall be amended, modified, waived or discharged orally
     or by course of conduct, but only by a written agreement signed by an
     authorized officer of Lender.  Lender shall not, by any act, delay,
     omission or otherwise be deemed to have expressly or impliedly waived any
     of its rights, powers and/or remedies unless such waiver shall be in
     writing and signed by an authorized officer of Lender.  Any such waiver
     shall be enforceable only to the extent specifically set forth therein.  A
     waiver by Lender of any right, power and/or remedy on any one occasion
     shall not be construed as a bar to or waiver of any such right, power
     and/or remedy that Lender would otherwise have on any future occasion,
     whether similar in kind or otherwise.

          (h)  Cumulative Remedies.  The rights and remedies provided in the
     Loan Documents are cumulative and not exclusive of any rights or remedies
     provided by law.

          (i)  Survival of Provisions.  All representations, warranties and
     covenants made in the Loan Documents shall survive the execution and
     delivery of the Loan Documents and the making of the Loan.  Such
     representations, warranties and covenants shall terminate only upon the
     full and final payment and performance by the Pledgor of the Obligations
     and termination of this Agreement and the Note.

          (j)  Term of Agreement.  This Agreement shall continue until the Note
     has been paid in full or discharged in accordance with the terms of this
     Agreement and until all Obligations of the Pledgor under the Loan Documents
     shall have been fully satisfied.

          (k)  Reinstatement.  To the extent permitted by law, the Loan
     Documents shall continue to be effective or be reinstated, as the case may
     be, if at any time any amount received by Lender, in respect of the
     Obligations is rescinded or must otherwise be restored or returned by
     Lender, upon the insolvency, bankruptcy, dissolution, liquidation or
     reorganization of Pledgor or upon the appointment of any receiver,
     intervenor, conservator, trustee or similar official for Pledgor or any
     substantial part of its assets, or otherwise, all as though such payments
     had not been made.

          (l)  Governing Law.  The validity, interpretation and enforcement of
     the Loan Documents and any dispute arising out of the relationship between
     the parties thereto, whether in contract, tort, equity or otherwise, shall
     be governed by the internal laws of the state of Texas (without giving
     effect to principles of conflicts of law).  Pursuant to Article 15.10(b) of
     Chapter 15 ("Chapter 15") of the Texas Credit Code, the parties hereto
     expressly agree that Chapter 15 shall not apply to the Loan Documents or to
     any advance, nor shall the Loan Documents or any Revolving Credit Advance
     be governed by or be subject to the provisions of Chapter 15 in any manner
     whatsoever.

          (m)  Choice of Forum.  Pledgor and Lender irrevocably consent and
     submit to the non-exclusive jurisdiction of the courts of the state of
     Texas located in Dallas, Texas and the United States District Court for the
     Northern District of Texas and waive any objection based on venue or forum
     non conveniens with respect to any action instituted therein arising under
     the Loan Documents or in any way connected with or related or incidental to
     the dealings of the parties hereto with respect to the Loan Documents or
     the transactions related thereto, in each case whether now existing or
     hereafter arising, and whether in contract, tort, equity or otherwise, and
     agree that any dispute with respect to any such matters shall be heard only
     in the courts described above (except that Lender shall have the right to
     bring any action or proceeding against Pledgor or its property in the
     courts of any other jurisdiction that Lender deems necessary or appropriate
     in order to realize on the Pledged Collateral or to otherwise enforce its
     rights against Pledgor or its property).

          (n)  Successors and Assigns.  The Loan Documents shall be binding upon
     and inure to the benefit of and be enforceable by Lender, Pledgor and their
     respective successors and permitted assigns, except that Pledgor may not
     assign its rights under this Agreement without the prior written consent of
     Lender.  Lender may assign its rights and delegate its obligations under
     the Loan Documents to another Person, in which event, the assignee or
     participant shall have, to the extent of such assignment or participation,
     the same rights and benefits as it would have if it were the Lender
     hereunder, except as otherwise provided by the terms of such assignment or
     participation.

          (o)  No Third-Party Rights.  The Loan Documents are not intended to
     and shall not be construed to create any rights in or confer any benefits
     on any persons other than the parties thereto and their respective
     successors and permitted assigns.

          (p)  Complete Agreement.  The Loan Documents represent the final
     agreement between the parties and may not be contradicted by evidence of
     prior, contemporaneous or subsequent oral agreements of the parties.  There
     are no unwritten oral agreements between the parties.

          (q)  Partial Invalidity.  If any provision of the Loan Documents is
     held to be invalid or unenforceable, such invalidity or unenforceability
     shall not invalidate the Loan Documents as a whole, but the Loan Documents
     shall be construed as though they did not contain the particular provision
     held to be invalid or unenforceable and the rights and obligations of the
     parties shall be construed and enforced only to such extent as shall be
     permitted by applicable law.

          (r)  Interpretation of Agreement.  Time is of the essence in each
     provision of the Loan Documents of which time is an element.  All terms not
     defined herein or in the Loan Documents shall have the meaning set forth in
     the applicable Uniform Commercial Code, except where the context otherwise
     requires.  Acceptance of or acquiescence in a course of performance
     rendered under the Loan Documents shall not be relevant in determining the
     meaning of the Loan Documents even though the accepting or acquiescing
     party had knowledge of the nature of the performance and opportunity for
     objection.

          (s)  Conflicts.  The terms and conditions of the Loan Documents are
     intended to complement and supplement each other and are to be construed so
     as to be consistent and complimentary.  In the event that a conflict of
     terms cannot be reconciled, the terms and conditions of the Credit
     Agreement will govern over any conflicting terms or conditions in any other
     Loan Document.

          (t)  Waiver of Notices.  Pledgor hereby expressly waives demand,
     presentment, protest and notice of protest and notice of dishonor with
     respect to any and all instruments and commercial paper, included in or
     evidencing any of the Obligations or the Pledged Collateral, and any and
     all other demands and notices of any kind or nature whatsoever with respect
     to the Obligations, the Pledged Collateral and the Loan Documents, except
     such as are expressly provided for in the Loan Documents.  No notice to or
     demand on Pledgor that Lender may elect to give shall entitle Pledgor to
     any other or further notice or demand in the same, similar or other
     circumstances.

          (u)  Notices.  All notices, demands or other communications to be
     given or delivered under or by reason of this Agreement shall be in writing
     (including telecopy, telegraphic, telex or cable communications) and
     mailed, telecopied, telegraphed, telexed, cabled or delivered:

     provision of the Loan Documents.

          (w)  Counterparts.  This Agreement may be executed in any number of
     separate counterparts and all of said counterparts taken together shall be
     deemed to constitute one and the same instrument.

be duly executed and delivered as of the date first above written.
