     Re:  Letter Agreement

Ladies and Gentlemen:

     BANQUE PARIBAS HOUSTON AGENCY ("Paribas"), SOCIETE GENERALE, SOUTHWEST
AGENCY ("SG") and BANQUE PARIBAS HOUSTON AGENCY as Agent for Paribas and SG
("Agent") (Paribas and SG, together with their successors and assigns, are
hereinafter individually called a "Bank" and collectively called "Banks") are
pleased to present the following terms and conditions for a line of credit and
letter of credit facility (the "Facility") to be extended to CONTRAN CORPORATION
("Borrower").

     Borrower, Paribas, SG and Agent hereby agree to the following terms and
conditions with respect to the Facility:

Borrower:           Contran Corporation.

Banks:              Paribas and SG and their successors and assigns.

Agent:              Paribas will act as Agent for Banks and, in such capacity,
                    will (a) make all advances of loans to Borrower under the
                    Facility ("Loans") upon its receipt of funds therefor from
                    Banks, and (b) receive all payments of principal, interest
                    and fees related to the Facility for the benefit of and
                    distribution to Banks as appropriate.  With respect to each
                    Loan, each Bank shall, not later than 10:00 a.m., Houston,
                    Texas time on the date such Loan is to be made available to
                    Borrower, make available its pro rata share of the requested
                    Loan, in immediately available funds, to Agent at Agent's
                    principal office in Houston, Texas.  Unless Agent shall have
                    received written notice from a Bank prior to the date of any
                    requested Loan that such Bank will not make available to
                    Agent such Bank's pro rata share of such Loan, Agent may
                    assume that such Bank has made such share available to Agent
                    on the date of such requested Loan and Agent may (but shall
                    not be obligated to), in reliance upon such assumption, make
                    available to Borrower on such date a corresponding amount. 
                    If and to the extent that such Bank shall not have made its
                    pro rata share thereof available to Agent, such Bank and
                    Borrower severally agree to pay to Agent, immediately upon
                    demand, such corresponding amount, together with interest
                    thereon for each day from the date of advance by Agent until
                    repaid to Agent at (A) with respect to Borrower, the Base
                    Rate and (B) with respect to such Bank, the weighted average
                    of rates on overnight Federal funds transactions with
                    members of the Federal Reserve System arranged by Federal
                    funds brokers, as published or quoted on the next succeeding
                    business day by the Federal Reserve Bank of New York (the
                    "Federal Funds Rate").  Before making any demand on Borrower
                    pursuant to the immediately preceding sentence, Agent agrees
                    with Borrower that Agent will make demand on such Bank
                    pursuant to the immediately preceding sentence.  If (and

                    only if) such Bank shall pay to Agent such corresponding
                    amount, such amount shall constitute such Bank's share of
                    the Loans for purposes of this Agreement.

Facility:           $20,000,000 (the "Committed Amount") aggregate committed
                    line of credit for loans (the "Loans") and letters of credit
                    (the "Letters of Credit"), subject to the Advance Rate (as
                    hereinafter defined) and the other terms and conditions of
                    this Agreement and the other Loan Papers (as hereinafter
                    defined).  The commitments of Banks under this Facility
                    shall expire on the earlier to occur of the Maturity Date 
                    (as hereinafter defined) or the occurrence of an Event of
                    Default.

Letter of Credit
Sublimit:           The amount available for drawing under outstanding Letters
                    of Credit from time to time shall not exceed $10,000,000 in
                    the aggregate, and the maturity of each Letter of Credit may
                    not exceed one (1) year from the issuance date and may not
                    extend beyond the Maturity Date.

Conditions
Precedent:               Banks' obligations to make each Loan and Paribas'
                         obligation to issue each Letter of Credit under this
                         Agreement shall be subject to the following conditions
                         precedent:

                    (a)  no Event of Default (as hereinafter defined), or
                         occurrence or event which, with the giving of notice or
                         lapse of time, or both, would become an Event of
                         Default, has occurred and is continuing or would result
                         from the making of the requested Loan or issuance of
                         the requested Letter of Credit;

                    (b)  all representations and warranties of Borrower
                         contained in the Loan Papers shall be true and correct
                         in all material respects with the same force and effect
                         as though made on and again as of the date of the
                         proposed Loan or proposed issuance of a Letter of
                         Credit, except to the extent that such representations
                         or warranties expressly relate to an earlier date; 

                    (c)  all covenants and agreements to have been complied with
                         and performed by Borrower on or before the date of such
                         proposed Loan or issuance of a Letter of Credit shall
                         have been fully complied with and performed to the
                         reasonable satisfaction of Required Banks (as
                         hereinafter defined);

                    (d)  with respect to a requested Loan bearing interest with
                         reference to the LIBOR Rate (as hereinafter defined) (a
                         "LIBOR Loan"), Borrower has requested such Loan from
                         Agent (and Agent has promptly thereafter notified Banks
                         of such request) at least three (3) LIBOR Business Days
                         (as such term is defined in the Promissory Notes, as
                         hereinafter defined) prior to the date such Loan is to
                         be made, specifying the amount of such Loan and the
                         LIBOR Interest Period (as defined in the Promissory
                         Notes) to be applicable thereto; and with respect to a
                         Loan bearing interest with reference to the Base Rate
                         (as hereinafter defined) (a "Base Rate Loan"), Borrower
                         has requested such Loan from Agent (and Agent has
                         promptly thereafter notified Banks of such request) at
                         least one (1) business day prior to the date such Loan
                         is to be made, specifying the amount of such Loan; and

                    (e)  with respect to a requested Letter of Credit, Borrower
                         has delivered to Agent a Letter of Credit Application
                         (as described herein) with respect thereto at least
                         three (3) business days prior to the date such Letter
                         of Credit is to be issued.

Issuer of Letters
of Credit:               Paribas shall be the issuer of the Letters of Credit;
                         provided, however, that:

                    (a)  immediately upon the issuance of any Letter of Credit,
                         Paribas shall be deemed to have sold to each other
                         Bank, and each other Bank shall be deemed
                         unconditionally and irrevocably to have purchased from
                         Paribas, without recourse or warranty, an undivided
                         interest and participation, the extent of such other
                         Bank's pro rata share (based upon Banks' respective
                         commitments under the Facility), in such Letter of
                         Credit, each drawing thereunder, the obligations of
                         Borrower with respect thereto and the security
                         therefor; upon any change in the pro rata share of any
                         Bank which may hereafter occur, it is agreed that, with
                         respect to all Letters of Credit then outstanding,
                         there shall be an automatic adjustment to the
                         participation hereby created to reflect the new pro
                         rata share of the assigning and assignee Banks; any
                         action taken or omitted by Paribas under or in
                         connection with a Letter of Credit, if taken or omitted
                         in the absence of gross negligence or willful
                         misconduct, shall not create any liability for Paribas;
                         and

                    (b)  in the event Paribas makes any payment under any Letter
                         of Credit and Borrower shall not have promptly
                         reimbursed such amount in full to Paribas pursuant to
                         the Letter of Credit Application relating thereto or
                         otherwise, Paribas shall promptly so notify each other
                         Bank of such failure, whereupon each other Bank shall
                         promptly and unconditionally pay to Paribas the amount
                         of such other's Bank's pro rata share of such
                         unreimbursed payment in immediately available funds;
                         all advances made by Paribas and any other Bank
                         directly or indirectly against drafts on any Letter of
                         Credit shall be deemed to be Loans under the Facility,
                         and shall bear interest with reference to the Base
                         Rate.

Letter of Credit
Application:             Paribas shall issue Letters of Credit for the account
                         of Borrower under the Facility after receipt of a
                         Letter of Credit Application (which shall include,
                         without limitation, a reimbursement agreement in the
                         event that amounts are funded by Paribas under any
                         Letter of Credit) in form and substance reasonably
                         satisfactory to Paribas, which Letter of Credit
                         Application shall be appropriately completed, shall
                         specify all information called for therein (including,
                         without limitation, the exact terms of the proposed
                         Letter of Credit which shall be in form and substance
                         satisfactory to Paribas) and shall be executed by
                         Borrower.

Purpose:            Borrower shall use the Loans to refinance existing debt, to
                    purchase margin stock and for other general corporate
                    purposes.  Borrower shall use the Letters of Credit to

                    support self insurance programs and workmen's compensation
                    claims.

Maturity Date:      October 31, 1992 (the "Maturity Date"), subject to
                    acceleration upon the occurrence of an Event of Default.

Security:           Banks shall have a perfected first priority security
                    interest in at least (a) 2,971,233 shares of common stock of
                    Keystone Consolidated Industries, Inc. ("Keystone") and (b)
                    2,258,369 shares of common stock of Baroid Corporation
                    ("Baroid").  Borrower shall deliver to Agent the stock
                    certificates representing the Keystone shares and
                    appropriate stock powers, executed in blank and in proper
                    form for transfer, relating thereto.  Borrower shall cause
                    the Baroid shares to be transferred to Morgan Guaranty Trust
                    Co. of New York Custodial Account No. 38573 for the account
                    of Banque Paribas, New York Branch, as agent for Agent, and
                    to thereby pledge the Baroid shares to Banks as provided in
                    the Security Agreement (as hereinafter defined).  Borrower
                    may, from time to time, pledge additional marketable
                    securities acceptable to Banks in their discretion,
                    including shares of common stock of Keystone and Baroid
                    which Banks hereby agree, in advance, are acceptable
                    collateral.

Advance Rate:       The advance rate for the making of Loans and issuance of
                    Letters of Credit (the "Advance Rate") may not exceed 49% of
                    the then current market value of the marketable securities
                    pledged to Banks in which Banks have a perfected, first
                    priority security interest ("Collateral").  For purposes of
                    this Agreement, the current market value of marketable
                    securities shall, as of the date of each determination
                    thereof, be based upon the most recent closing price for
                    such securities on the relevant national securities exchange
                    in New York (or, if any such security is not traded on an
                    exchange in New York, the place where such security is so
                    traded); in the event of any conflict, the most recent
                    closing price on the New York Stock Exchange shall control.



Collateral Value
Maintenance:             Should the aggregate outstanding credit at any time
                         under the Facility (i.e., the aggregate of the
                         outstanding principal amount of the Loans plus the
                         amount available for drawing under outstanding Letters
                         of Credit) exceed 49% of the then current market value
                         of the Collateral, Borrower shall either (a) repay the
                         Loans to the extent of such excess, or (b) pledge to
                         Banks additional collateral acceptable to Banks so that
                         the aggregate outstanding credit at any time under the
                         Facility shall not exceed 49% of the then current
                         market value of the Collateral.

Compliance with
Regulation U;
Withdrawal or
Substitution of 
Collateral;              Borrower and Banks will strictly comply at all times
                         with the provisions of Regulation U of the Board of
                         Governors of the Federal Reserve System, as from time
                         to time revised, amended or supplemented.  At the time
                         of the making of any Loan or issuance of any Letter of
                         Credit under this Agreement, and after giving effect
                         thereto, the aggregate amount of (a) principal of all
                         Loans then outstanding plus (b) the amount available

                         for funding under outstanding Letters of Credit, may
                         not exceed forty-nine percent (49%) of the then current
                         market value of all margin stock Collateral.  If at any
                         time Borrower desires to withdraw or substitute
                         Collateral, Borrower may do so if but only if (i) any
                         Collateral to be substituted is margin stock Collateral
                         acceptable to Banks and (ii) after giving effect to any
                         such withdrawal or substitution, the aggregate amount
                         of (A) principal of all Loans then outstanding plus (B)
                         the amount available for funding under outstanding
                         Letters of Credit, does not exceed forty-nine percent
                         (49%) of the then current value of the margin stock
                         Collateral pledged to Banks.

Borrowing Rates:         Borrower's option of Base Rate (as defined in the
                         Promissory Notes), or 30, 60 or 90-day reserve adjusted
                         Libor + 1-3/4% (the "LIBOR Rate").  Agent shall, in a
                         reasonably prompt fashion, notify Borrower and Banks of
                         the LIBOR Rate applicable to any Loan for a particular
                         interest period after the determination thereof is
                         made.  Interest for LIBOR Loans shall be calculated on
                         the basis of a 360 day year, and actual days elapsed. 
                         Except as provided in the immediately preceding
                         sentence, interest and fees shall be calculated on the
                         basis of a 365 or 366 day year, as the case may be, and
                         actual days elapsed.  Interest shall be payable
                         quarterly, except that interest for Libor Loans shall
                         be payable on the last day of each interest period.

Commitment Fee:          Borrower shall pay to Agent, on behalf of Banks, a
                         commitment fee in the amount of 1/2% per annum on the
                         average daily unused and available commitments, payable
                         quarterly in arrears on the last day of each calendar
                         quarter.  (For purposes hereof, the unfunded amount
                         under outstanding Letters of Credit shall be deemed to
                         be a "used" portion of the commitments.)

Letter of Credit Fee:    Borrower shall pay to Agent, on behalf of Banks and for
                         the period and from the date of issuance of each Letter
                         of Credit until the expiration or termination date
                         thereof, a Letter of Credit fee in the amount of 1% per
                         annum of the original face amount (with respect to the
                         initial fee) or undrawn amount (with respect to
                         subsequent fees) thereof, as the case may be at the
                         time of payment, payable upon issuance and quarterly
                         thereafter in advance.  In addition, Borrower shall pay
                         to Paribas, for the period from the date of issuance of
                         each Letter of Credit until the expiration or
                         termination date thereof, a Letter of Credit "fronting
                         fee" in the amount of 1/8% per annum of the original
                         face amount (with respect to the initial fee) or
                         undrawn amount (with respect to subsequent fees)
                         thereof, as the case may be at the time of payment,
                         payable upon issuance and quarterly thereafter in
                         advance.

                         therewith, become due and payable in full and the
                         commitments hereunder shall immediately, and
                         concurrently therewith, terminate, without any action

                         harmless Agent, each Bank and each director, officer,
                         employee and affiliate of Agent or any Bank from and
                         against any and all actions, suits, proceedings

                         losses, damages, liabilities or expenses of any kind or
                         nature whatsoever (but excluding consequential losses)
                         which may be incurred by or asserted against or involve
                         Agent or any Bank or any such director, officer,
                         employee or affiliate, as a result of or  arising out

                         such action, suit, proceeding (including any inquiry or
                         investigation) or claim, except for any such claims,
                         damages or liabilities to the extent the same are

                         attributable to the willful malfeasance or gross
                         negligence of the person or entity seeking to be
                         indemnified.  Except with respect to Agent as provided
                         below, Borrower shall not be obligated to provide any
                         indemnification hereunder for losses, damages,

                         or among Banks and Agent; provided, however, that Agent
                         shall be so indemnified therefor hereunder when acting
                         in its capacity as Agent.  This provision shall survive

                              loss, cost or expense incurred by such Bank as a
                              result of (i) any payment or prepayment of any
                              portion of any LIBOR Loan on a date other than the
                              last day of the interest period applicable
                              thereto, (ii) the conversion of the rate of
                              interest on any LIBOR Loan from the LIBOR Rate to
                              another rate of interest available hereunder
                              (subject to the provisions of this Agreement
                              applicable to the selection of any such interest
                              rate) with respect to any portion of the LIBOR
                              Loan on a date other than the last day of the
                              interest period applicable thereto, (iii) the
                              failure to borrow any requested LIBOR Loan after
                              request therefor or the rescinding of a notice of
                              a conversion from another interest rate to the
                              LIBOR Rate prior to the commencement of the
                              interest period, or (iv) the failure of all or any
                              portion of a LIBOR Loan to be made under this
                              Agreement due to the action or inaction of
                              Borrower, including Borrower's failure to satisfy
                              any condition precedent to the making of any LIBOR
                              Loan.  

                    (b)  If at any time any Bank reasonably determines that
                         deposits in Dollars in the appropriate amount for the
                         appropriate period are not being offered in the London
                         interbank market, or that adequate and reasonable means
                         do not exist for ascertaining the LIBOR Rate, or that
                         it is unlawful or not feasible for such Bank to make or
                         continue to maintain all or any portion of a LIBOR
                         Loan, then, upon notice to Borrower and Agent, the
                         LIBOR Loan or proposed LIBOR Loan or portion thereof so
                         affected shall be automatically converted to or be a
                         Base Rate Loan.

                         paragraph (a) (1) of Rule 144, of Baroid; and each of
                         Borrower and Valhi fully paid the price of the Baroid

                         by Borrower for greater than three (3) years within the

Governing Law:      State of Texas; provided, however, that Borrower, Agent and
                    Banks agree that, except for Section 15.10(b) thereof, the
                    provisions of Art. 5069-15.01 et seq. of the Revised Civil
                    Statutes of Texas, 1925, as amended (regulating certain
                    revolving credit loans and revolving tri-party accounts)
                    shall not apply to the Loans, this Agreement, the Promissory
                    Notes or the other Loan Papers.


Fees and Expenses of
Counsel to Agent
and Banks; Enforcement
and Collection Costs
and Expenses:       Borrower agrees to pay the reasonable fees and out-of-pocket
                    expenses of counsel to Agent and Paribas in connection with
                    the establishment of this Facility.  In addition, Agent
                    reserves the right to employ outside counsel for Agent
                    and/or Banks subsequent to the establishment of this
                    Facility if the need so arises in the good faith opinion of
                    Agent, whereupon the reasonable fees and expenses related
                    thereto shall be paid by Borrower; provided, however, that

                    Borrower shall not be obligated to pay the fees and expenses
                    of more than one law firm in connection therewith and such
                    fees and expenses for which Borrower is obligated must
                    relate to amendments of the Loan Papers, waivers under the
                    Loan Papers and/or the Collateral.  Whether or not any such
                    counsel is employed, and notwithstanding the foregoing,
                    Borrower shall pay all reasonable out-of-pocket costs and
                    expenses of Agent and/or any Bank (including, without
                    limitation, fees and expenses of their counsel) relating to
                    (a) enforcing the rights and remedies of Agent and each Bank
                    and (b) collecting the Loans and other indebtedness of
                    Borrower under this Agreement, the Promissory Notes, the
                    Security Agreement and the other Loan Papers.

Other Expenses:          By executing a copy of this Agreement, Borrower agrees
                         (regardless of whether any Loans are made or Letters of
                         Credit are issued hereunder) to pay all reasonable
                         out-of-pocket costs and expenses of Agent and Banks
                         incurred to establish this Facility, the cost of any
                         tax, duty or other similar assessment of reserve,
                         special deposit or other requirements incurred as a
                         result of this Facility and resulting from the
                         introduction or implementation of, or any change in, or
                         compliance with, any law, rule or regulation, or
                         interpretation thereof, whether such cost be direct or
                         indirect, and including, without limitation, those
                         costs or the like that have the effect of reducing the
                         return on any Bank's capital to a level below that
                         which such Bank would have achieved but for such
                         introduction, implementation, change or compliance, but
                         excluding, however, any such tax or imposition imposed
                         on the income of Banks or capital or franchise taxes
                         imposed by the jurisdiction under the laws of which any
                         Bank is organized or in which it maintains a place of
                         business.  Such payments shall be in addition to the 
                         fees otherwise provided for herein.

                         Note dated October 31, 1991, in the original principal
                         amount of $10,000,000 made by Borrower payable to the
                         order of Paribas (the "Paribas Note"), (c) Promissory
                         Note dated October 31, 1991, in the original principal

                         SG Note, together with all renewals, extensions,
                         amendments and replacements thereof from time to time,

                         Notes"), and (d) all other agreements, documents and
                         instruments executed or delivered in connection
                         herewith (this Agreement, the Security Agreement, the
                         Promissory Notes and such other agreements, documents
                         and instruments are hereinafter collectively called the
                         "Loan Papers") all of which are incorporated herein by
                         reference for all purposes, shall apply, and shall
                         govern the relationship among Borrower, Agent and Banks
                         with respect to the Facility.  In the event of any
                         direct conflict between the terms and provisions of
                         this Agreement and the terms and provisions of any
                         Promissory Note, the terms and provisions of such
                         Promissory Note shall control.

Agency Matters:          The parties hereto agree that Paribas, in its capacity
                         as Agent hereunder, shall act as agent for Paribas, SG
                         and the other Banks hereunder for purposes of
                         coordinating advances, issuing Letters of Credit,
                         receiving payments and the holding of Collateral and
                         for whatever other purposes as to which Banks may
                         mutually agree; provided, however, that (a) Paribas
                         (individually and/or as Agent) shall not be a fiduciary
                         or trustee of any kind or nature for the benefit of
                         Borrower, SG or any other Bank and shall not have any
                         fiduciary duty or trust relationship of any kind or
                         nature to or with Borrower, SG or any other Bank; and
                         (b) Paribas (individually and/or as Agent) shall not
                         have any liability whatsoever to Borrower, SG or any
                         other Bank except as may result from Paribas' gross
                         negligence or willful misconduct.  Each Bank has
                         performed its own credit analysis with respect to the
                         Facility, and no Bank is relying upon any
                         representation or warranty of Paribas in connection
                         therewith.

Pro Rata Share:          Each Bank shall, subject to its rights of assignment
                         contained herein and the other terms and conditions
                         hereof, have a fifty percent (50%) interest in the
                         total commitment under this Facility, the Loans, the
                         Letters of Credit and the Collateral to be made or to
                         exist concurrently herewith and in the future.  Banks'
                         obligations under this Agreement shall be several and
                         not joint, and Banks' obligations and rights with
                         respect to the Facility shall be pari passu except if
                         and to the extent that Banks may agree otherwise.  Each
                         Bank agrees that if it shall, through the exercise of a
                         right of bankers' lien, setoff or counterclaim against
                         Borrower or otherwise, obtain payment in respect of any
                         indebtedness owing to such Bank as a result of which
                         the unpaid portion of its Loans is proportionately less
                         than the unpaid portion of the Loans of other Banks
                         (based upon the respective commitments of Banks), then
                         the benefits thereof shall be shared among Banks pro
                         rata and such adjustments shall be made from time to
                         time as shall be equitable to ensure such pro rata
                         treatment.

Counterparts:            This Agreement may be executed in one or more
                         counterparts.

Amendment:               This Agreement, the Promissory Notes, the Security
                         Agreement and the other Loan Papers may not be amended
                         without the prior written consent of Borrower and Banks
                         that, at the time of such amendment, hold or own, in
                         the aggregate, 66-2/3% or more of the sum of the
                         aggregate principal amount of all Loans then
                         outstanding plus the aggregate undrawn amount of all
                         Letters of Credit then outstanding, or, if no Loans or
                         Letters of Credit are then outstanding, 66-2/3% or more
                         of the aggregate commitments hereunder (which Banks are
                         herein called "Required Banks"); provided, however,
                         that, without the prior written consent of all Banks,
                         no amendment or waiver shall (a) change the principal
                         amount of, or extend the maturity of or any date for
                         the payment of any principal of or interest on, any
                         Loan or Letter of Credit, or waive or excuse any such
                         payment or any part thereof, or change the rate of
                         interest on any Loan or Letter of Credit, (b) change
                         any commitment or other obligations (if any) of any
                         Bank or the provisions of this section of this

                         Agreement, (c) waive any condition precedent to the
                         making of any Loan or the issuance of any Letter of
                         Credit, (d) authorize the acceptance of marketable
                         securities, other than shares of common stock of
                         Keystone and Baroid, as Collateral for purposes of
                         Borrower's compliance with the terms and provisions of
                         this Agreement, (e) change the amount or due date of
                         any fee payable to Agent or any Bank, or (f) increase
                         the amount of the aggregate commitments of Banks or,
                         without each Bank's consent, the commitment of such
                         Bank; provided, further, that no such amendment shall
                         change or otherwise affect the rights or duties of
                         Agent hereunder without the prior written consent of
                         Agent.

Assignment:              Banks may (a) assign all or any portion of their
                         rights, interests and obligations herein and in the
                         Loans and Letters of Credit under this Facility to
                         other financial institutions, and (b) sell
                         participation interests herein and in the Loans and
                         Letters of Credit under this Facility, upon the giving
                         of written notice thereof to Borrower; provided,
                         however, that Paribas may not assign its obligation to
                         issue Letters of Credit in accordance with the terms
                         hereof without the prior consent of Borrower, which
                         consent shall not be unreasonably withheld.  Upon any
                         assignment pursuant to clause (a) preceding, the
                         assigning Bank shall be relieved of all of its
                         obligations under this Agreement and the other Loan

                         purposes of this Agreement and the other Loan Papers
                         and shall assume such obligations in full.
