                                TO SCHEDULE 13D

     This amended statement on Schedule 13D (this "Statement") relates to the
common stock, $1.00 par value per share (the "Shares"), of Keystone Consolidated
Industries, 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 following:

     (a)  This Statement is filed by Contran Corporation, a Delaware corporation
("Contran"), and, by virtue of the positions reported below, 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.

     Contran, NL Industries, Inc. ("NL") and Valhi, Inc. ("Valhi") are the
direct holders of approximately 38.7%, 3.5% and 0.2%, respectively, of the
9,297,533 Shares outstanding as of November 10, 1997 according to the Company's
Quarterly Report on Form 10-Q for the quarter ended September 30, 1997 (the
"Outstanding Shares").  Valhi and Tremont Corporation ("Tremont") are the direct
holders of approximately 57.9% and 17.7%, respectively, of the outstanding
common stock of NL and together may be deemed to control NL.  Valhi Group, Inc.
("VGI"), National City Lines, Inc. ("National"), the Harold Simmons Foundation,
Inc. (the "Foundation"), the Contran Deferred Compensation Trust No. 2 (the
"CDCT No. 2"), NL and Valmont Insurance Company ("Valmont") are the direct
holders of approximately 35.1%, 5.2%, 3.7%, 3.5%, 0.5% and 0.5%, respectively,
of the outstanding common stock of Tremont.  Together, VGI and National may be
deemed to control Tremont.  Valhi is the holder of 100% of the outstanding
common stock of Valmont and may be deemed to control Valmont.  VGI, National and
Contran are the direct holders of approximately 74.7%, 10.0%, and 7.6%,
respectively, of the outstanding common stock of Valhi.  Together, VGI, National
and Contran may be deemed to control Valhi.  National, NOA, Inc. ("NOA") and
Dixie Holding Company ("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 Louisiana Land Company, Inc.
("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 Agricultural Corporation, Inc. ("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 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 Valhi, VGI, National, NOA, Dixie Holding and Contran.  Mr.
Simmons is also chairman of the board and chief executive officer of Dixie Rice
and Southwest. Additionally, Mr. Simmons is chairman of the board of NL and is a
director of Tremont.

     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 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 CDCT No. 2 directly holds approximately 0.2% and 3.5% of the
outstanding shares of Valhi and Tremont common stock, respectively.  Boston Safe
Deposit and Trust Company serves as trustee of the CDCT No. 2 (the "Trustee").
Contran established the CDCT No. 2 as an irrevocable "rabbi trust" to assist
Contran in meeting certain deferred compensation obligations that it owes to
Harold C. Simmons.  If the CDCT No. 2 assets are insufficient to satisfy such
obligations, Contran must satisfy the balance of such obligations.  Pursuant to
the terms of the CDCT No. 2, Contran (i) retains the power to vote the shares
that Contran contributed to the CDCT No. 2, (ii) retains dispositive power over
such shares and (iii) may be deemed the indirect beneficial owner of such
shares.

     The Foundation directly holds approximately 2.7% of the Outstanding Shares.
 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.

     The Combined Master Retirement Trust (the "CMRT") directly holds less than
1.0% of the Outstanding Shares and the outstanding shares of Tremont and Valhi
common stock, respectively.  The CMRT is a trust formed by Valhi to permit the
collective investment by trusts that maintain the assets of certain employee
benefit plans adopted by Valhi 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. Mr. Simmons, however, disclaims beneficial
ownership of any shares held by the CMRT, except to the extent of his vested
beneficial interest therein.

     By virtue of the holding of such 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 and the Trusts disclaim
such beneficial ownership of the Shares beneficially owned, directly or
indirectly, by any of such entities.

     Harold C. Simmons' spouse is the direct beneficial owner of 10,500 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 Valmont and NL beneficially owned
1,000,000 shares and 1,186,200 shares, respectively, of Valhi common stock as of
the date of this report. The Reporting Persons further understand that the
shares of Valhi common stock owned by Valmont and NL are treated as treasury
stock by Valhi for voting purposes and for the purposes of this Statement.

     Certain information concerning the directors and executive officers of
Contran, including offices held by Mr. Simmons is set forth on Schedule A
attached hereto and incorporated herein by reference.

     (c)  Contran is a diversified holding company engaged through its

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

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.

     Except as described in this Item 4, none of the Reporting Persons nor, to
the best knowledge of such persons, any other person named in Schedule A to the

Borrower not later than 11:00 A.M. (Dallas time) (i) on the third Business Day
prior to the date of a proposed Eurodollar Advance, or (ii) on the Business Day
of a proposed Prime Rate Advance.  Each such notice from the Borrower of a
request for Advance (a "Notice of Borrowing") shall be in writing and shall be

date of such Advance, (ii) whether the Advance is to be a Prime Rate Advance or
a Eurodollar Advance, (iii) the aggregate Dollar amount of such Advance, and
(iv) in the case of a Eurodollar Advance, the initial Interest Period for such
Advance.  Each Notice of Borrowing shall be irrevocable and binding on the
Borrower.

     (c)  Each request for a Letter of Credit shall be made on notice given by
the Borrower not later than 11:00 A.M. (Dallas time) at least three Business
Days prior to the date a proposed Letter of Credit is to be issued, in the form
of Exhibit "D" attached hereto, specifying (i) the requested date of issuance of
such proposed Letter of Credit, (ii) the face amount of such proposed Letter of
Credit, (iii) the form of such proposed Letter of Credit, which must be a
standby Letter of Credit in form acceptable to the Bank, and (iv) the expiry
date of such proposed Letter of Credit, which expiry date shall in no event be

as such payment by the Bank, provided, however, that in the event the conditions
precedent for a Prime Rate Advance are satisfied on the date of such payment by
the Bank (other than the delivery of a Notice of Borrowing) and the Borrower has
not otherwise notified the Bank that it intends to repay such Reimbursment
Obligations with its own funds on such day, such Reimbursment Obligation shall
be automatically deemed to be a Prime Rate Advance by the Bank for the account
of the Borrower made as of the date of such payment by the Bank.

     (a)  Interest shall accrue on the unpaid principal amount of each
Eurodollar Advance at a rate per annum equal at all times to the lesser of (i)
the Adjusted Eurodollar Rate plus one and one half percent (1 1/2%), and (ii)
the Maximum Rate; provided that any amount of principal which is not paid when
due (whether at stated maturity, by acceleration or otherwise) shall bear
interest from the date on which such amount is due until such amount is paid in
full, payable on demand, at a rate per annum equal at all times to the lesser of
(i) the greater of (A) the Adjusted Prime Rate in effect from time to time plus
two percent (2%) and (B) the rate required to be paid on such Advance
immediately prior to the date on which such amount became due plus two percent
(2%) and (ii) the Maximum Rate.

     (b)  Interest shall accrue on the unpaid amount of each Prime Rate Advance
at a rate per annum equal at all times to the lesser of (i) the Adjusted Prime
Rate, and (ii) the Maximum Rate; provided, that any amount of principal which is
not paid when due (whether at stated maturity, by acceleration or otherwise)
shall bear interest from the date on which such amount is due until such amount
is paid in full, payable on demand, at a rate per annum equal at all times to
the lesser of (i) the rate required to be paid on such Advance immediately prior
to the date on which such amount becomes due plus two percent (2%) and (ii) the
Maximum Rate.

     (c)  Accrued interest for each Advance shall be due and payable on each
Interest Payment Date for such Advance.  There shall be no more than three (3)
Interest Periods applicable to Eurodollar Advances hereunder at any one time.

     (d)  At least three Business Days prior to the end of any Interest Period
applicable to an outstanding Eurodollar Advance, the Borrower shall, by notice
to the Bank, select a new Interest Period to be applicable to such Advance or
request that such Advance be converted to a Prime Rate Advance at the end of the
Interest Period then applicable thereto.  If the Bank does not receive such
notice it will automatically convert such Eurodollar Advance to a Prime Rate
Advance at the end of the Interest Period then applicable thereto.  At any time
upon three Business Days prior notice to the Bank, the Borrower may convert all
or any portion of a Prime Rate Advance (but not less than $1,000,000 and an
integral multiple of $100,000) into a Eurodollar Advance having an Interest
Period as selected by the Borrower.

     (e)  If at any time the Bank determines that Dollars are not available to
the Bank in the London interbank market for any Interest Period requested by the
Borrower, or it is otherwise impossible to have Eurodollar Advances, then, the
Borrower agrees that (i) the obligation of the Bank to make or maintain
Eurodollar Advances shall be suspended until such time as the Bank gives notice
to the Borrower that the circumstances giving rise to such suspension no longer
exist, (ii) each requested Advance thereafter shall be a Prime Rate Advance, and
(iii) each outstanding Eurodollar Advance shall be converted to a Prime Rate
Advance on the last day of the then applicable Interest Period.

     (f)  In the event the rate of interest chargeable under this Agreement or
the Note at any time is greater than the Maximum Rate, the unpaid principal
amount of the Note shall bear interest at the Maximum Rate until the total
amount of interest paid or accrued on the Note equals the amount of interest
which would have been paid or accrued on the Note if the stated rates of
interest set forth in this Agreement had at all times been in effect.  In the
event, upon payment in full of the Note, the total amount of interest paid or
accrued under the terms of this Agreement and the Note is less than the total
amount of interest which would have been paid or accrued if the rates of inter-
est set forth in this Agreement had, at all times, been in effect, then the
Borrower shall, to the extent permitted by applicable law, pay the Bank an
amount equal to the difference between (i) the lesser of (A) the amount of
interest which would have been charged on the Note if the Maximum Rate had, at
all times, been in effect and (B) the amount of interest which would have
accrued on the Note if the rates of interest set forth in this Agreement had at
all times been in effect and (ii) the amount of interest actually paid or
accrued under this Agreement on the Note.  In the event the Bank ever receives,
collects or applies as interest any sum in excess of the Maximum Rate, such
excess amount shall, to the extent permitted by law, be applied to the reduction
of the principal balance of the Note, and if no such principal is then outstand-
ing, such excess or part thereof remaining shall be paid to the Borrower.

     Section 2.3  Fees.

     (a)  On the last day of each March, June, September and December thereafter
and on the Termination Date, the Borrower shall pay to the Bank a commitment fee
of one half of one percent (1/2%) of the average daily unborrowed portion of the
Commitment (borrowings to include for this purpose both outstanding Advances and
the undrawn face amount of outstanding Letters of Credit) during the preceding
quarter (or in the case of the first such payment, during the period from the
Effective Date to the date such payment is due, and in the case of the last such
payment, during the period from the immediately preceding payment of such fee to
the Termination Date), calculated on the basis of a 360-day year.

     (b)  The Borrower shall pay to the Bank a letter of credit fee in
connection with each Letter of Credit equal to one and one half of one percent
(1 1/2%) per annum of the amount available for drawing under such Letter of
Credit, from and including the issuance date thereof to but excluding the date
such Letter of Credit expires or is terminated, such fee to be payable quarterly
in arrears on the last date of each March, June, September and December and on
the Termination Date, calculated on the basis of a 360-day year for the number
of days elapsed.

     Section 2.4    Payments and Computations.

     (a)  All payments hereunder or under the Note shall be made to the Bank at
its offices at 4800 Trammell Crow Center, 2001 Ross Avenue, Dallas, Texas,
75201, or at such other address or addresses as the Bank may designate for such
purpose from time to time by written notice to the Borrower, without any
presentment thereof.  The Borrower shall make all payments hereunder or under
the Note not later than 12:00 noon (Dallas time) on the day when due to the Bank
in Dollars in immediately available funds.

     (b)  Whenever any payment hereunder or under the Note shall be stated to be
due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest at the rate then effective.

     (c)  Interest hereunder shall be computed on the basis of a 360-day year,
in the case of the Eurodollar Rate, and on the basis of a 365 or 366-day year,
as applicable, in the case of the Adjusted Prime Rate, for the actual number of
days elapsed, including the first day but excluding the last day.

     Section 2.5  Illegality.  Notwithstanding any other provision of this
Agreement, if the introduction of or any change in or in the interpretation of
any law or regulation shall make it unlawful, or any central bank or other
Governmental Authority shall assert that it is unlawful, for the Bank to make or
maintain Eurodollar Advances or to perform its obligations hereunder, the
Borrower agrees that upon notice to the Borrower by the Bank, (a) the obligation
of the Bank to make or maintain Eurodollar Advances shall be suspended while
such unlawfulness exists or is asserted, (b) the Borrower shall forthwith pay
interest on such Advances at the Adjusted Prime Rate, and (c) the Borrower shall
indemnify the Bank for all losses, expenses and liabilities as provided in
Section 2.11 hereof.

     Section 2.6  Increased Costs.  If the enactment or adoption of any Legal
Requirement or if any change in any Legal Requirement or in the interpretation
thereof by any court or regulatory body or other Governmental Authority charged
with the administration thereof or compliance by the Bank with any request or
directive (whether or not having the force of law) or any such court, or
governmental or regulatory authority or central bank shall either (i) impose,
modify or deem applicable any reserve, special deposit, capital or similar
requirement against any extension of credit by, or assets of, or any deposits or
other liabilities of, the Bank or (ii) impose on the Bank any tax, duty or other
charge with respect to this Agreement or any condition regarding this Agreement,
and the result of any event referred to in clauses (i) or (ii) above shall be to
increase the cost to the Bank of maintaining Eurodollar Advances or issuing or
maintaining Letters of Credit or to reduce the amounts receivable by the Bank
hereunder in connection with Eurodollar Advances or Letters of Credit (which
increase in cost or reduction in amounts receivable shall be the result of the
Bank's reasonable allocation of the aggregate of such cost increases or
reductions resulting from such events), then, within ten days of demand by the
Bank, the Borrower shall pay to the Bank from time to time as specified by the
Bank, additional amounts which shall be sufficient to compensate the Bank for
the portion of such increased cost or reduction allocable to the Borrower,
together with interest on each such amount accruing from the date five days
after the date payment of such amount was demanded until payment of such amount
in full at the Adjusted Prime Rate.  A certificate setting forth in reasonable
detail such increased cost or reduction incurred by the Bank as a result of any
event mentioned in clause (i) or (ii) above, submitted by the Bank to the
Borrower, shall be conclusive, absent manifest error, as to the amount thereof,
provided that the Borrower shall not be obligated to pay such cost or reduction
unless the Bank shall have similar terms as its general policy applicable to
similar borrowers electing to borrow funds subject to Eurodollar Rate interest
provisions or requesting letters of credit.  The protection of this paragraph
(a) shall be available to the Bank regardless of any possible contention of
invalidity or inapplicability of the Legal Requirement which has been imposed,
unless such Legal Requirement is ultimately determined to be invalid or
inapplicable and the result of such determination is to retroactively eliminate
the increase in cost or reduction of amounts receivable resulting from such
Legal Requirement.

     Section 2.7  Taxes/Net Payments.

     (a)  Any and all payments by the Borrower hereunder or under the Note shall
be made free and clear of and without deduction for any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, however, income, capital and
franchise taxes imposed by the United States or a state or other political
subdivision thereof (all taxes, levies, imposts, deductions, charges,
withholdings and liabilities referred to in this sentence (other than such
excluded income, capital and franchise taxes imposed by the United States or a
state or other political subdivision thereof) are herein referred to as
"Taxes").  If the Borrower shall be required by law to deduct any Taxes from or
in respect of any sum payable hereunder or under the Note, (i) the sum payable
shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.7) the Bank receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrower shall make such
deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable law
and in a manner such that the Bank shall not be required to make any deduction
or payment of any Taxes.

     (b)  If the Bank shall be required by law to make any deduction or payment
with respect to any payment made by the Borrower for any present or future
taxes, levies, imposts, deductions, charges, withholdings or liabilities with
respect thereto, excluding, however, income, capital and franchise taxes imposed
by the United States or a state or other political subdivision thereof (all
taxes, levies, imposts, deductions, charges, withholdings and liabilities
referred to in this sentence (other than such excluded income, capital and
franchise taxes imposed by the United States or a state or other political
subdivision thereof) are herein referred to as "Other Taxes"), (i) the Borrower
agrees to pay such Other Taxes to the relevant taxation authority or other
authority in accordance with applicable law and in a manner such that the Bank
shall not be required to make any such deduction or payment of any Other Taxes,
and (ii) the Bank may, at its option upon notice to the Borrower, pay such Other
Taxes, and the Borrower agrees to reimburse immediately the Bank for the amount
so paid plus interest thereon from the date so paid until reimbursed at the
Adjusted Prime Rate.

     (c)  The Borrower will indemnify, and does hereby indemnify, the Bank for
the full amount of Taxes and Other Taxes (including, without limitation, any
Taxes and Other Taxes imposed by any jurisdiction on amounts payable by the
Borrower or the Bank under this Section 2.7) paid by the Bank and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto.  Payment under such indemnification shall be made within 30 days from
the date the Bank makes written demand therefor from time to time, provided that
such indemnification shall only be required if the Bank shall have similar terms
as its general policy applicable to similar borrowers.

     Section 2.8  Interest on Overdue Amounts.  In the event that any Advances
are not paid when due or any interest thereon or other amount payable by the
Borrower hereunder is not paid when due the Borrower shall pay interest on any
such overdue amount, to the extent permitted by law, from and including the date
such amount becomes due to but excluding the date paid (calculated on the basis
of a 360-day year), at the Default Rate, such interest to be due and payable on
demand by the Bank.

     Section 2.9  Mandatory Prepayments.  If at any time (a) the sum of  the
aggregate amount of outstanding Advances plus the aggregate amount of unpaid
Reimbursement Obligations plus the aggregate undrawn face amount of all
outstanding Letters of Credit exceeds (b) the Borrowing Base, the Borrower
shall, within one Business Day of the notice thereof from the Bank, either (i)
prepay Advances in an amount equal to such excess, such prepayment to be applied
first to outstanding Prime Rate Advances and then to outstanding Eurodollar
Advances, and, if necessary thereafter, will provide cash collateral for
outstanding Letters of Credit in an amount equal to such remaining excess,
and/or (ii) provide an Acceptable Lien on such additional Collateral
satisfactory to the Bank in its sole discretion with a Current Market Value such
that after giving effect thereto and any amendments deemed necessary in the sole
discretion of the Bank to reflect such additional Collateral and its inclusion
in the Borrowing Base, and after recalculating the Borrowing Base, there remains
no such excess which is not dollar for dollar cash collateralized.  Provided
that the Borrower has first pledged to the Bank all unencumbered Keystone Shares
owned by the Borrower, the Bank agrees that shares of common stock of Valhi,
Inc., a Delaware corporation, owned by the Borrower shall be acceptable
additional Collateral with a Borrowing Base value equal to 49% of the Current
Market Value for each such share of Valhi, Inc. pledged.

     Section 2.10  Optional Prepayments.  The Borrower may prepay any Advance in
full or in part upon at least (i) three Business Days' notice to the Bank in the
case of Eurodollar Advances, or (ii) one Business Day notice to the Bank in the
case of Prime Rate Advances, in each case stating the proposed date and
principal amount of the prepayment, and if such notice is given, the Borrower
shall prepay such principal amount with accrued interest to the date of such
prepayment on the principal amount prepaid; provided, however, that any such
prepayment in connection with any Eurodollar Advance shall be made only on the
last day of the then current Interest Period applicable thereto; and provided,
further, that all prepayments shall be in integral multiples of $100,000 and no
Eurodollar Advance remaining outstanding shall be an amount less than
$1,000,000.

     Section 2.11  Compensation.  The Borrower shall compensate the Bank, upon
written request by the Bank, for all losses, expenses and liabilities (i) if any
prepayment or conversion of any Eurodollar Advance occurs on a date which is not
the last day of the Interest Period for such Advance being prepaid or converted,
(ii) if any prepayment or conversion of any Eurodollar Advance is not made on
any date specified in a notice of prepayment given by the Borrower pursuant to
Section 2.10 hereof or notice of conversion given by the Borrower pursuant to
Section 2.2 hereof, (iii) as a result of any failure to borrow any Eurodollar
Advance requested pursuant to a Notice of Borrowing, whether due to failure by
the Borrower to fulfill on or before the date specified for such Eurodollar
Advance the applicable conditions specified in Article IV or otherwise, or
(iv) as a consequence of the timing of any acceleration of the Eurodollar
Advances pursuant to Section s 9.2 or 9.3 hereof, or conversion of the
Eurodollar Advances to the alternative interest rate calculation as provided in
Section 2.5 hereof, including (without limitation) any loss or expense incurred
in liquidating or employing deposits from third parties and loss of interest or
other profit for the period after such prepayment, acceleration or conversion;
provided that the Bank shall have delivered to the Borrower a certification in
reasonable detail as to the amount of such loss or expense, which certification
shall be binding on the Borrower in the absence of manifest error; and provided
further that the Bank shall have similar terms as its general policy applicable
to similar borrowers electing to borrow funds subject to Eurodollar Rate
interest provisions.

     Section 2.12  Termination or Reduction of Commitment.  The Borrower may at
any time terminate or reduce the unused amount of the Commitment, upon three
days prior written notice to the Bank, in integral multiples of $1,000,000;
provided, however, that any such termination or reduction shall be permanent,
and the Borrower shall not be entitled to reinstate or increase the amount of
the Commitment.

     Section 2.13  Obligations Absolute.  To the fullest extent permitted by
applicable law, the obligations of the Borrower under this Agreement in
connection with Letters of Credit shall be absolute, unconditional and
irrevocable, and shall be paid or performed strictly in accordance with the
terms of this Agreement, under all circumstances whatsoever, including, without
limitation, the following circumstances:

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

     (b)  any amendment or waiver of or any consent to depart from the terms of
this Agreement, the Pledge Agreement, or any Letter of Credit (with the consent
of the Borrower and any beneficiary of such Letter of Credit);

     (c)  the existence of any claim, set-off, defense or other right that the
Borrower may have at any time against any beneficiary or any transferee of any
Letter of Credit, the Bank or any other Person, whether in connection with this
Agreement, or any transactions contemplated hereby or thereby or any unrelated
transaction;

     (d)  any statement or any other document presented under any Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect
or any statement therein being untrue or inaccurate in any respect whatsoever,
provided that payment by the Bank under any Letter of Credit shall not have
constituted gross negligence or willful misconduct of the Bank;

     (e)  any nonapplication or misapplication by the beneficiary of any Letter
of Credit or otherwise of the proceeds of any drawing under any Letter of
Credit;

     (f)  payment by the Bank under any Letter of Credit against presentation of
a draft or certificate that does not comply with the terms of such Letter of
Credit, provided that payment by the Bank under such Letter of Credit shall not
have constituted gross negligence or willful misconduct of the Bank;

     (g)  the failure by the Bank to honor any drawing under any Letter of
Credit or to make any payment demanded under any Letter of Credit on the ground
that the demand for such payment does not conform to the terms and conditions
such Letter of Credit, provided that such failure shall not have constituted
gross negligence or willful misconduct of the Bank; and

     (h)  any other circumstance or happening whatsoever, including the
circumstances described in Section 2.14, whether or not similar to any of the
foregoing, provided that such circumstances or happening shall not have
constituted gross negligence or willful misconduct of the Bank.

     Section 2.14  Limited Liability of the Bank.

     (a)  Notice of Bank's Duties.  As between the Bank and the Borrower, the
Borrower assumes all risk of the acts or omissions of any beneficiary of a
Letter of Credit with respect to its use of such Letter of Credit.  Neither the
Bank, its correspondents, its affiliates nor any of their officers or directors
shall be liable or responsible for:

    (i)   the use which may be made of any Letter of Credit or for any actions
          or omissions of any beneficiary of any Letter of Credit;

   (ii)   the existence or nonexistence of a default under any instrument
          secured or supported by any Letter of Credit or any other event which
          gives rise to a right to call upon any Letter of Credit;

  (iii)   the failure of any instrument to bear any reference or adequate
          reference to any Letter of Credit;

   (iv)   the form, validity, sufficiency, accuracy, genuineness or legal effect
          of any document submitted in connection with the application for and
          issuance of, or the making of a drawing under, any Letter of Credit,
          even if it should in fact prove to be in any or all respect invalid,
          insufficient, inaccurate, fraudulent or forged;

    (v)   the validity or sufficiency of any instrument transferring or
          assigning or purporting to transfer or assign any Letter of Credit or
          the rights or benefits thereunder or proceeds thereof, in whole or in
          part, that may prove to be invalid or ineffective for any reason;

   (vi)   the failure of the beneficiary of any Letter of Credit to comply fully
          with all conditions required in order to effect a drawing;

  (vii)   errors, omissions, interruptions, losses, or delays in transmission or
          delivery of any messages, by mail, cable, telegraph, telex, telecopier
          or otherwise;

 (viii)   any consequences arising from causes beyond the control of the Bank;
          and

   (ix)   any act, error, neglect or default, omissions, insolvency or failure
          in the business of any of the Bank's correspondents, for any refusal
          by the Bank or any of the Bank's correspondents to pay or honor drafts
          drawn under any Letter of Credit because of any applicable law, now or
          hereafter enforced, or for any matter beyond the control of the Bank
          and its affiliates;

except only that the Borrower shall have a claim against the Bank for acts or
events described in the immediately preceding clauses (ii) through (ix), and the
Bank shall be liable to the Borrower, to the extent, but only to the extent, of
any direct, as opposed to consequential, damages suffered by the Borrower which
the Borrower proves were caused by (A) the Bank's willful misconduct or gross
negligence in determining whether documents were presented under any Letter of
Credit comply with the terms of any Letter of Credit or (B) the Bank's willful
failure or gross negligence in failing to pay under such Letter of Credit after
the presentation to it by the beneficiary of a sight draft and any required
document strictly complying with the terms and conditions of the such Letter of
Credit.

     (b)  No Duty to Inquire.  The Borrower agrees that the Bank is authorized
and instructed to accept and pay drawings under any Letter of Credit without
requiring, and without responsibility for, the determination as to the existence
of any event giving rise to such drawing, either at the time of acceptance of
documents presented in connection with such drawing, upon payment of such
drawing by the Bank or thereafter.  The Borrower agrees that the Bank is under
no duty to determine the proper identity of anyone presenting documents under
any Letter of Credit in connection with a drawing or otherwise (whether by
tested telex or otherwise) as the officer, representative or agent of any
beneficiary under the such Letter of Credit and payment by the Bank to any such
beneficiary when requested by any such purported officer, representative or
agent is hereby authorized and approved by the Borrower.  In furtherance and not
in limitation hereof, the Bank may accept documents that appear on their face to
be in order, without responsibility for further investigation, regardless of any
notice or information to the contrary.


                                  ARTICLE III
                                    SECURITY

     Section 3.1  Collateral.  As security for the Indebtedness and the perfor-
mance of all other obligations of the Borrower to the Bank pursuant to this
Agreement and the other Loan Documents, the Borrower agrees that at all times
the Bank shall have an Acceptable Lien on all Collateral.  In connection
therewith, the Bank agrees that the Borrower may, at any time prior to the
Termination Date when no Default has occurred and is continuing, withdraw or
substitute Collateral if (i) the substitute Collateral is margin stock
acceptable to the Bank in its sole discretion and any changes deemed necessary
in the sole discretion of the Bank to the Loan Documents are made to reflect
such substitution of Collateral, and (ii) the Borrowing Base is redetermined to
give effect to such withdrawal or substitution, and the sum of the aggregate
outstanding amount of Advances plus the aggregate amount of unpaid Reimbursement
Obligations plus the aggregate amount available to be drawn under outstanding
Letters of Credit does not exceed such redetermined Borrowing Base.

     Section 3.2  Further Assurances.  The Borrower agrees to execute or to
cause the execution of such further financing statements, instruments or
documents as may be necessary from time to time in the opinion of the Bank to
effect the intent of this Article III.

     Section 3.3  Collateral After the Termination Date.  Except as otherwise
set forth in this Section , if any Letters of Credit remain outstanding on or
after the Termination Date, but all other non-contingent obligations of the
Borrower hereunder have been paid in full and no Default has occurred and is
continuing, the Borrower shall provide cash collateral to the Bank on or before
sixty days after the Termination Date having an aggregate fair market value
equal to the aggregate undrawn amount of such outstanding Letters of Credit for
deposit in the Collateral Account (as defined in the Pledge Agreement), and such
cash collateral shall secure the Borrower's continuing obligations in respect of
such outstanding Letters of Credit subject to the terms of the Pledge Agreement.
In the event the Bank receives such cash collateral on or prior to the date
required, the Bank shall release the Pledged Shares to the Borrower and any
other Collateral subject to the terms of the Pledge Agreement (other than the
cash collateral just received by the Bank from the Borrower); provided, however,
that such Pledged Shares and the lien of the Bank on such other Collateral shall
not be released, and the Borrower shall not be obligated to provide such cash
collateral if, on or before the earlier of the date sixty days after the
Termination Date or the date of the proposed release any Default specified in
Section 8.1(f) or Section 8.1(g) shall have occurred.  In the event that, for
whatever reason, the Borrower fails to provide cash collateral as required
pursuant to this Section , then notwithstanding anything to the contrary in the
Pledge Agreement, the Bank may, at its discretion, sell, transfer, dispose of or
otherwise liquidate all or any portion of the Pledged Shares or such other
Collateral and hold the proceeds thereof in the Collateral Account as cash
collateral to secure the Borrower's contingent obligations in respect of the
outstanding Letters of Credit.


                                   ARTICLE IV
                              CONDITIONS PRECEDENT

     The Borrower represents and warrants to the Bank as follows:

     Section 5.1  Organization and Authority.  The Borrower is a corporation

to which the Borrower is a party and to perform all of its obligations pursuant
to each of them. The Loan Documents and all other documents and agreements

of any provisions of any Other Instruments, and the execution and delivery of
this Agreement, the consummation of the transactions contemplated hereby, the
execution and delivery of the instruments contemplated hereby, and fulfillment
of the terms and compliance with the provisions hereof and thereof do not and
will not result in a material violation or breach of, or constitute a default
under or result in any Lien (other than in favor of the Bank) upon any
Collateral under any of the Other Instruments.  The Borrower is not a party to
or bound by any contract or subject to any restriction which could reasonably be
expected to cause a Material Adverse Change.  The Borrower is not required to
obtain any consent, approval or authorization of, or to make any registration,
declaration or filing with, any government or government entity as a condition
precedent to the valid execution and delivery of this Agreement or any other
instrument or agreement contemplated hereby and the valid issue and delivery of
the Note as contemplated hereby, except for such consent, approval,
authorization, registration, declaration or filing, the failure to so obtain or
make would not cause a Material Adverse Change.

     Section 5.3  Financial Condition.  The Borrower has delivered to the Bank
its financial statements dated as of December 31, 1996 (such statements are
collectively referred to herein as "the Financial Statements").  The Financial
Statements have been prepared in accordance with GAAP consistently applied, and
fairly present the financial condition of the Borrower as of December 31, 1996.
No Material Adverse Change has occurred since December 31, 1996.

     Section 5.4  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 which could not reasonably be expected to
cause a Material Adverse Change.

     Section 5.5  Title to Collateral; Liens.

     (a)  The Borrower has good and indefeasible title to all Collateral.  All
Keystone Shares constituting part of the Collateral, and all Keystone Shares or
other securities which may subsequently be pledged as Collateral (i) are not
subject to any restrictions on sale or transfer except for any restrictions
regarding compliance with applicable securities laws and (ii) either (A) are
not, and will not be, "restricted securities" as such term is used or defined in
paragraph (a)(3) of Rule 144, or (B) if and to the extent such shares are or
will be "restricted securities" as so defined, such shares have been held by the
Borrower for greater than two (2) years within the meaning of and as calculated
pursuant to the holding period provisions of paragraph (d) of Rule 144.  The
Borrower fully paid the purchase price of all Keystone Shares constituting part
of the Collateral at the time it acquired such Keystone Shares, and did not give
a promissory note or enter into any installment purchase contract or other
obligation to or with respect to the transferor of such Keystone Shares as any
part of its payment of the purchase price of such Keystone Shares.  As of the
date of this Agreement, the Borrower is an "affiliate" of Keystone, as such term
is defined in the rules and regulations of the Securities and Exchange
Commission.

     (b)  Except for the Liens contemplated by this Agreement, all of the
Collateral is free and clear of any and all Liens.  The execution and delivery
of the Loan Documents and the delivery of certificates evidencing the Pledged
Shares, together with executed stock powers relating thereto, to the Bank will
create Acceptable Lien in favor of the Bank on all of the Collateral.

     Section 5.6    Tax Returns.  Except as previously disclosed to the Bank in
writing 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) which
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.

     Section 5.7  Investment Company Act.  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.

                                   ARTICLE VI
                             AFFIRMATIVE COVENANTS

     Until the Commitment has terminated and all Letters of Credit have expired
or been terminated and the Bank has received full payment of the Indebtedness,
the Borrower covenants and agrees as follows:

     Section 6.1  Information.  The Borrower will deliver or cause to be
delivered to the Bank all of the following:

     (a)  as soon as reasonably possible, but in any event within one hundred
twenty (120) days after the close of each fiscal year of the Borrower, the
audited consolidated financial statements of the Borrower and its consolidated
Subsidiaries, containing a balance sheet, statement of income and retained
earnings and cash flows (such financial statements to be prepared in accordance
with GAAP consistently applied and duly certified by independent public
accountants of recognized standing reasonably acceptable to the Bank);

     (b)  as soon as reasonably possible, but in any event within sixty (60)
days after the close of each quarter of each fiscal year of the Borrower, the
unaudited consolidated financial statements of the Borrower and its consolidated
Subsidiaries for such quarter, containing a balance sheet, statement of income
and retained earnings and cash flows (such quarterly financial statements shall
be prepared in accordance with GAAP consistently applied and shall be duly
certified as accurate in all material respects by the Chief Financial Officer of
the Borrower);

     (c)  such other information concerning the Borrower and the Collateral as
the Bank may from time to time reasonably request.

     Section 6.2  Taxes.  The Borrower will pay and discharge to pay and
discharge all taxes, assessments and governmental and other charges and claims
levied or imposed on or which, if unpaid when due, might become a lien or charge
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.

     Section 6.3  Conduct of Business.  The Borrower will take or cause to be
taken all such actions as from time to time may be necessary to preserve and
keep in full force and effect the Borrower's corporate existence under the laws
of its state of incorporation and franchises in every jurisdiction in which the
nature of its business requires it to be qualified, if the failure to so qualify
could reasonably be expected to cause a Material Adverse Change, and to continue
to conduct and operate its business and financial affairs substantially as such
affairs have been conducted and operated.  The Borrower will maintain, preserve,
protect, and keep all of its assets material to the operation of its business in
good condition, reasonable wear and tear excepted.

     Section 6.4  Use of Proceeds.  The Borrower shall use the proceeds of the
Advances solely for working capital and other general corporate purposes,
including without limitation, to refinance debt and to purchase margin stock.
The Borrower shall request Letters of Credit solely to support  contingent
obligations of the Borrower (other than obligations in respect of borrowed
money) and, in the case of Letters of Credit issued for the joint and several
account of the Borrower and a Subsidiary or affiliate of the Borrower, to
support contingent obligations of such Subsidiary or affiliate (other than
obligations in respect of borrowed money).

     Section 6.5  Notification of Adverse Events.  The Borrower will give the
Bank prompt and full written notice of:

     (a)  the occurrence of any Default or Event of Default; and

     (b)  any other event or occurrence which could reasonably be expected to
cause a Material Adverse Change.

     Section 6.6  Costs.  The Borrower will reimburse the Bank on demand for all
reasonable out-of-pocket costs and expenses of the Bank, including without
limitation charges and disbursements of legal counsel for the Bank, in
connection with the transactions contemplated by this Agreement and all other
Loan Documents and the preparation of, amendment to, or waiver of any provision
in this Agreement and such other Loan Documents, or arising in connection with
the enforcement of the Loan Documents.

     Section 6.7  Compliance with Legal Requirements.  The Borrower will comply
at all times in all material respects with all Legal Requirements of any
Governmental Authority having jurisdiction over it or its business.

     Section 6.8  Maintenance of Insurance. The Borrower will maintain insurance
with responsible and reputable insurance companies or associations in such
amounts and covering such risks as are usually carried by companies engaged in
similar businesses and owning similar properties in the same general areas in
which the Borrower, operates, except where failure to maintain any such
insurance could not reasonably be expected to cause a Material Adverse Change;
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 condi-
tion that are part of a group of companies under common control.

     Section 6.9  Inspection.  From time-to-time upon reasonable notice or after
an Event of Default has occurred, permit any Persons designated by the Bank to
visit, audit, and inspect any of the properties of the Borrower, including its
financial and accounting records, and to make copies and take extracts
therefrom, and to discuss its affairs, finances, and accounts with its officers
and independent public accountants with respect to any matters concerning or
relating to this Agreement or the transactions contemplated herein, all upon
reasonable notice during normal business hours and as often as may be reasonably
requested while such Default exists.  All reasonable costs and expenses incurred
by the Bank in connection therewith shall be borne by the Borrower.

the Borrower covenants and agrees that, without the prior written consent of the
Bank:

     Section 7.1  Corporate Transactions.  The Borrower will not consolidate
with or merge with or into any other corporation or partnership unless the
Borrower shall be the survivor of such consolidation or merger, and the Borrower

of its Property.

     Section 7.2  Sale of Collateral.  The Borrower will not sell or otherwise
transfer any Property which is Collateral.

     Section 7.3  Liens.  The Borrower will not allow or permit to exist on or

except for the security interest in favor of the Bank hereunder.

     Section 7.4  Debts, Guaranties and Other Obligations.  The Borrower will

     (b)  Debt of the Borrower hereunder to the Bank;

     (d)  The Borrower either (i) violates its covenant in Section 7.4 and such

     (e)  The Borrower or Keystone suffers a judgment against it which, within

case of notice by telecopy, when received in a clear and comprehensible fashion
addressed as set forth above; provided that all payments made to the Bank and
all requests for Advances under Article II hereof shall be deemed to have been
made at such time as such payments or requests are actually received by the
Bank.

     Section 9.2  Amendments and Waivers.  This Agreement may not be amended
except in writing executed by the Bank and the Borrower.  Each waiver of any of
the terms or conditions hereunder shall be in writing and executed by the Bank.

     Section 9.3  Participations.  The Bank may sell participations to one or
more banks or other financial institutions (each, a "Participant") in or to all
or a portion of its rights and obligations under this Agreement, provided,
however, that the Bank's obligations under this Agreement (including, without

performance of such obligations, (iii) the Bank shall remain the holder of the
Note for all purposes of this Agreement, and (iv) the Borrower shall continue to

obligations under this Agreement.  The Borrower hereby agrees that Participants
shall have the same rights under Section s 2.5, 2.6, 2.7, 2.11 and 9.9 hereof as
the Bank to the extent of their respective participations.

     Section 9.4  Multiple Counterparts.  This Agreement may be executed in
multiple counterparts, each of which shall be deemed an original but all of
which together shall constitute one and the same instrument.

     Section 9.5  Successors and Assigns.  This Agreement and the other Loan
Documents shall inure to the benefit of the Bank and its successors and assigns
and shall be binding upon the Borrower and its successors and assigns.  The
Borrower's obligations and rights under this Agreement and the other Loan
Documents may not be assigned by the Borrower.

     Section 9.6  Severability.  If any provision of this Agreement is rendered
or declared invalid, illegal or ineffective by reason of any existing or
subsequently enacted legislation or by decree of a court of competent
jurisdiction, such legislation or decree shall not impair, invalidate or nullify
the remainder of this Agreement which shall remain in full force and effect.

     Section 9.7  Interpretations.  In the event that any representations,
warranties, covenants or agreements contained in this Agreement directly
conflict with provisions relating to the same subject matter in any of the Loan
Documents, the provisions of this Agreement shall be controlling for all
purposes.

     Section 9.8  Usury Not Intended.  No provision of this Agreement, the Note
or any other Loan Document executed in connection herewith shall require or be
construed to require the payment or permit the charging or collection of
interest in an amount or at a rate in excess of the maximum non-usurious rate
under applicable law.  If any excess of interest in such respect is hereby
provided for, or shall be adjudicated to be so provided, in the Note or
otherwise in connection with the Advances, the provisions of this Section 9.8
shall govern and prevail, and neither the Borrower nor the sureties, guarantors,
successors or assigns of the Borrower shall be obligated to pay the excess
amount of such interest, or any other excess sum paid for the use, forbearance
or detention of sums loaned pursuant hereto.  In the event the Bank ever
receives, collects, or applies as interest any such sum, such amount which would
be in excess of the maximum non-usurious rate shall be applied as a payment and
reduction of the principal indebtedness evidenced by the Note; and, if the
principal amount of the Note has been paid in full, any remaining excess shall
forthwith be paid to the Borrower.  All amounts paid in connection with this
Agreement and the Note which would under applicable laws be deemed to be
"interest" shall, to the extent permitted by such applicable laws, be amortized,
prorated, allocated and spread throughout the full term of this Agreement and
the Note.

     Section 9.9  Indemnification.  The Borrower hereby agrees to indemnify the
Bank, and each affiliate thereof and its directors, officers, employees, agents
and counsel ("Indemnified Persons") from, and discharge, release, and hold each
of them harmless against, any and all losses, liabilities, claims or damages to
which any of them may become subject, that arise out of, result from, or relate
to (i) any actual or proposed use by the Borrower of the proceeds of any
Advance, (ii) any breach by the Borrower of any representation, warranty,
covenant, or other  provision of this Agreement or any other Loan Document,
(iii) any environmental claim, environmental permit, requirement of
environmental laws or regulations, or any release or threatened release of
hazardous substances, concerning or relating to the present or previously-owned
or operated properties, operations, or business of the Borrower, and (iv) any
investigation, litigation or other proceeding (including any threatened
investigation or proceeding) relating to the foregoing, and the Borrower shall
reimburse each Indemnified Person upon demand for any reasonable out-of-pocket
expenses (including legal fees) incurred in connection with any such
investigation, litigation or other proceeding, other than any such losses,
liabilities, claims, damages or expenses incurred by reason of the gross
negligence or willful misconduct of the Indemnified Person.

     Section 9.10  Confidentiality.  The Bank may furnish any information
concerning the Borrower in the possession of the Bank from time to time to
participants (including prospective participants); provided that, prior to any
such disclosure, the participant or proposed participant shall agree in writing
to preserve the confidentiality of any confidential information relating to the
Borrower received by it from such Bank.

     Section 9.11  Survival of Certain Provisions.  Notwithstanding anything
herein or in any other Loan Document to the contrary, the provisions set forth
in Section s 2.5, 2.6, 2.7, 2.11 and 9.9 hereof shall survive the payment in
full of the Indebtedness and the termination of this Agreement.

     Section 9.12  Governing Law.  THIS AGREEMENT, THE NOTE AND THE OTHER LOAN
DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF TEXAS.  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 THIS AGREEMENT OR TO ANY ADVANCE, NOR SHALL THIS
AGREEMENT OR ANY ADVANCE BE GOVERNED BY OR BE SUBJECT TO THE PROVISIONS OF
CHAPTER 15 IN ANY MANNER WHATSOEVER.

     PURSUANT TO SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE, A LOAN
AGREEMENT IN WHICH THE AMOUNT INVOLVED IN THE LOAN AGREEMENT EXCEEDS $50,000 IN
VALUE IS NOT ENFORCEABLE UNLESS THE LOAN AGREEMENT IS IN WRITING AND SIGNED BY
THE PARTY TO BE BOUND OR THAT PARTY'S AUTHORIZED REPRESENTATIVE.

     THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE
PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN LOAN AGREEMENT,
AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED
INTO THE LOAN AGREEMENT.  THIS WRITTEN AGREEMENT AND THE LOAN DOCUMENTS, AS
DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG 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.

$10,000,000                                                     November 5, 1997


     For value received, the undersigned, CONTRAN CORPORATION, a Delaware
corporation ("Borrower"), promises to pay to the order of SOCIETE GENERALE,
SOUTHWEST AGENCY ("Bank"), at the offices of the Bank at 4800 Trammell Crow

States of America, which shall be legal tender in payment of all debts and dues,
public and private, (i) the lesser of Ten Million Dollars ($10,000,000) or all
unpaid Advances (as defined in the Credit Agreement described herein) recorded
on the schedule attached hereto from time to time outstanding and (ii) interest
on the unpaid balance of each Advance from time to time outstanding from the
date such Advance is made until the maturity thereof as provided for under the
terms of the Credit Agreement ("Contract Rate").  The principal of and interest

unpaid principal of Advances hereunder shall bear interest for such date at the
maximum non-usurious rate under applicable law.

     The Borrower consents to the recordation by the Bank of all Advances and
repayments thereof, as well as payments of interest thereon, on the schedule
attached hereto, or on a continuation of such schedule attached to and made a

     The Borrower and the Bank are party to the Credit Agreement dated as of the
date hereof (as the same may be amended from time to time, the "Credit
Agreement"). In order to induce the Bank to enter into the Credit Agreement, the
Borrower is entering into this Pledge Agreement to secure its obligations under
the Credit Agreement.  For good and valuable consideration the receipt and
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:

                            SECTION 1.  Definitions.

     Terms defined in the Credit Agreement and not otherwise defined in this
Pledge Agreement have the meanings provided for in the Credit Agreement.  The
following additional terms, have the following respective meanings:

     "Approved Depositary" means The Depository Trust Company or any other
depository which has been approved by the Bank and as to which the Bank has

Bank to the effect that the Bank will have valid and perfected security

     "Collateral" means (a) the Pledged Securities, (b) the Collateral Account,

of the Borrower in respect thereof) and the Collateral Account, (d) all non-cash
dividends and all other payments and distributions hereafter made on or with
respect to the Pledged Securities and, following the occurrence and during the
continuation of a Default, all cash dividends paid on the Pledged Securities and
all interest on the Collateral Account, and (e) all proceeds of any or all of
the foregoing (whether the same arise or are acquired before or after the
commencement of a Proceeding in which the Borrower is a debtor).

     "Collateral Account" has the meaning set forth in Section 6 of this Pledge
Agreement.

this Pledge Agreement, as such Annex may be amended from time to time by the
written agreement of the Borrower and the Bank.

perfection or the effect of perfection or non-perfection of the Acceptable Lien
on any Collateral is governed by the Uniform Commercial Code as in effect in a
jurisdiction other than Texas, "UCC" means the Uniform Commercial Code as in
effect in such other jurisdiction for purposes of the provisions hereof relating
to such perfection or the effect or perfection or non-perfection (and for
purposes of definitions related to such provisions).

                  SECTION 2.  Representations and Warranties.

     The Borrower represents and warrants that:

     (a)  The Borrower is the record and beneficial owner of each item of
Collateral existing on the date of this Pledge Agreement free and clear of all
Liens except the Lien created hereunder.  The Borrower will be the record and
beneficial owner of each item of Collateral hereafter acquired in addition to
any then existing Collateral free and clear of all Liens except the Lien created
hereunder.  The Borrower is not and will not become a party to or otherwise
bound by any agreement, other than this Pledge Agreement, which restricts in any
manner the rights of any present or future holder of any of the Pledged
Securities with respect thereto.

     (b)  The capital stock of Keystone is duly authorized, validly issued and
fully paid and non-assessable. All of the initial Pledged Securities have been
beneficially owned by the Borrower for a period in excess of two years.

     (c)  Upon (i) delivery to the Bank of all Pledged Securities other than
Pledged Securities which have been deposited in an Approved Depositary, and (ii)
the making of appropriate entries under Section 8-320 of the UCC to the Bank's
account on the books of an Approved Depositary of all Pledged Securities which
have been deposited with such Approved Depositary, the Bank will have Acceptable
Lien on such Collateral.  The Borrower has not performed any acts which might
prevent the Bank from enforcing any of the terms and conditions of this Pledge
Agreement or which would limit the Bank in any such enforcement.

     (d)  The principal place of business and chief executive office of the
Borrower, and the office where the Borrower keeps its books and records, is
located at the address of the Borrower designated in Section 9.1 of the Credit
Agreement.  The Borrower does not do business and has not done business within
the past five years under a trade name or any name other than its legal name set
forth at the beginning of this Pledge Agreement.

                      SECTION 3.  The Security Interests.

     (a)  In order to secure the full and punctual payment of the Secured
Obligations in accordance with the terms thereof, and to secure the performance
of all the obligations of the Borrower hereunder and under the other Credit
Documents, the Borrower hereby grants to the Bank continuing security interests
in the Collateral, whether presently existing or owned or hereafter arising or
acquired.

     (b)  The security interests granted hereby are granted as security only and
shall not subject the Bank to, or transfer or in any way affect or modify, any
obligation or liability of the Borrower with respect to any of the Collateral or
any transaction in connection therewith.

                 SECTION 4.  Perfection of Security Interests.

     (a)  Prior to the date the initial Advance is made, or the initial Letter
of Credit is issued  under the Credit Agreement, and thereafter upon each
acquisition of any Pledged Securities and each investment or reinvestment of
funds deposited in the Collateral Account pursuant to Section 7 of this Pledge
Agreement, the Borrower shall (i) deliver or cause to be delivered to the Bank
all previously undelivered certificates and instruments evidencing Pledged
Securities other than Pledged Securities which have been deposited in an
Approved Depositary and (ii) give all notices and take such other action as may
be necessary to perfect the Bank's security interest in any Pledged Securities
which have been deposited with an Approved Depositary.

     (b)  All Pledged Securities other than Pledged Securities which have been
deposited with an Approved Depositary shall be delivered to the Bank in suitable
form for transfer by delivery, or shall be accompanied by duly executed
instruments of transfer or assignment in blank, with signatures appropriately
guaranteed, and accompanied in each case by any required transfer tax stamps,
all in form and substance reasonably satisfactory to the Bank.

     (c)  The Borrower shall cause each Approved Depositary  to make appropriate
entries to the Bank's account on the books of such Approved Depositary to
reflect the transfer of all Pledged Securities which have been deposited with
such Approved Depositary to the Bank and to deliver to the Bank a written
confirmation of the book-entry transfer of such Pledged Securities into such
account, to be held as Collateral under this Pledge Agreement.

     (d)  Promptly following the Borrower's acquisition of any Pledged Security
which constitutes an "uncertificated security" as defined in the UCC, the
Borrower and the Bank will effect such modifications to this Pledge Agreement as
the Bank in its discretion deems necessary or appropriate to ensure that the
security interests with respect to such portion of the Collateral are protected
to substantially the same extent as provided for herein with respect to other
Pledged Securities and the Borrower shall provide evidence satisfactory to the
Bank of compliance by the Borrower with Section 5 hereof with respect to such
portion of the Collateral.

     (e)  The Borrower shall notify the issuer of each of the Pledged Securities
of the Lien on the Pledged Securities provided hereby and shall cause such
issuer, within ten Business Days of the date of such notice from the Borrower,
to send written notice to the Bank acknowledging such Lien and expressly
agreeing to remit any and all dividends and distributions on account of the
Pledged Securities of such issuer (other than cash dividends) remitted after the
date of this Pledge Agreement directly to the Bank, and, upon receipt by such
issuer of  any notice from the Bank that a Default has occurred and is
continuing, to remit all cash dividends and any and all other distributions on
account of the Pledged Securities directly to the Bank.

                        SECTION 5.  Further Assurances.

     The Borrower will, from time to time, at its expense and in such manner and
form as the Bank may reasonably require, execute and deliver any financing
statement, specific assignment, notice or other writing and take any other
action that may be necessary or desirable, or that the Bank may reasonably
request, in order to create, preserve, perfect or validate the security
interests granted hereby or to enable the Bank to exercise and enforce its
rights hereunder with respect to any of the Collateral.  To the extent permitted
by applicable law, the Borrower hereby authorizes the Bank to execute and file,
in the name of the Borrower or otherwise, UCC financing statements which the
Bank in its sole discretion may deem necessary or appropriate to perfect the
security interests granted hereby.  The Borrower agrees that a carbon,
photographic, photostatic or other reproduction of this Pledge Agreement or of a
financing statement is sufficient as a financing statement.  The Borrower shall
pay the costs of, or incidental to, any recording or filing of any financing or
continuation statements concerning the Collateral.

                        SECTION 6.  Collateral Account.

     There shall be established and, at all times thereafter until  this Pledge
Agreement shall have terminated, there shall be maintained with the Bank an
account designated "Collateral Account Societe Generale for Contran Corporation"
(the "Collateral Account").  All proceeds of dividends and other payments and
distributions on Pledged Securities  (and following the occurrence and during
the continuation of a Default, all cash dividends paid on account of Pledged
Securities), and all cash collateral received by the Bank at any time pursuant
to the terms of the Credit Agreement, shall be deposited directly into the
Collateral Account and thereafter shall be held and applied by the Bank in
accordance with this Pledge Agreement.  If any such proceeds, payments or
distributions in respect of the Pledged Securities are received by the Borrower
at any time after occurrence and during the continuance of a Default, they shall
be received in trust for the benefit of the Bank, and shall be deposited by the
Borrower forthwith into the Collateral Account in the same form as received
(with any necessary endorsement).  No amount, including interest on funds in the
Collateral Account, shall be paid or released to or for the account of, or
withdrawn by or for the account of, the Borrower or any other Person from the
Collateral Account except as provided in this Pledge Agreement.

SECTION 7.  Investment of Funds Deposited in the Collateral Account; Release of
                                     Funds.

     (a)  So long as no Default shall have occurred and be continuing, the
Borrower may direct the investment and reinvestment by the Bank of all funds on
deposit in the Collateral Account in accordance with the following terms and
conditions:

               (i)  such funds will be invested solely in Qualified Investments;
          and

               (ii) prior to or contemporaneously with the making of any such
          investment, the Borrower shall in accordance with Section 4 of this
          Pledge Agreement take or cause to be taken such steps as may be
          necessary to insure that the Bank will have an Acceptable Lien on such
          investment.

     (b)  So long as no Default shall have occurred and be continuing, the
Borrower shall be entitled to receive from the Bank all interest or other income
with respect to all funds on deposit in the Collateral Account.

     (c)  Each request by the Borrower for investment or release of funds in or
from the Collateral Account shall be deemed to be a representation and warranty
by the Borrower that (i) such investment or withdrawal is in accordance with the
terms and conditions specified in subsection (a) of this Section or for the
purposes specified in subsection (b) of this Section, as applicable, (ii) the
representations and warranties set forth herein are true and correct on and as
of the date of such request as if made on and as of such date; and (iii) no
Default has occurred and is continuing on the date of such request.

  SECTION 8.  Record Ownership of Pledged Securities; Definitive Certificates.

     The Bank may at any time following the occurrence and during the
continuation of a Default, from time to time, in its sole discretion, cause any
or all of the Pledged Securities to be transferred of record into the name of
the Bank or a nominee.  The Borrower will promptly give to the Bank copies of
any notices and other communications received by it with respect to Pledged
Securities registered in the name of the Borrower, and the Bank will promptly
give the Borrower copies of any notices and other communications received by the
Bank with respect to Pledged Securities registered in the name of the Bank or a
nominee.  The Bank shall at all times have the right to obtain definitive
certificates (in its name or in the name of a nominee) representing Pledged
Securities at any time deposited with an Approved Depositary, and all such
certificates shall be Collateral hereunder and be subject to the terms hereof.

    SECTION 9.  Right to Vote Pledged Securities; Receipt of Dividends, Etc.

     (a)  Unless a Default shall have occurred and be continuing, the Borrower
shall have the right, from time to time, to vote and to give consents,
ratifications and waivers with respect to the Pledged Securities, and the Bank
shall, upon receiving a written request from the Borrower, which request shall
be deemed to be a representation and warranty by the Borrower that no Default
has occurred and is continuing, deliver to the Borrower or, as specified in such
request, such proxies, powers of attorney, consents, ratifications and waivers
in respect of any Pledged Securities which are registered in the name of the
Bank or a nominee as shall be specified in such request and be in form and
substance satisfactory to the Bank.

     (b)  If a Default shall have occurred and be continuing, all rights of the
Borrower to exercise the voting and other consensual rights which it would
otherwise be entitled to exercise pursuant to Section 9(a) above shall end upon
thirty days' notice from the Bank to the Borrower and thereafter the Bank shall
have the right to the extent permitted by law for so long as such Default
continues, and the Borrower shall take all such action as may be necessary or
appropriate to give effect to such right, to vote and to give consents,
ratifications and waivers, and take any other action with respect to all Pledged
Securities with the same force and effect as if the Bank were the absolute and
sole owner thereof.

     (c)  The Bank shall be entitled to receive and retain as Collateral all
dividends and distributions (other than cash dividends or distributions) made in
respect of the Pledged Securities, whether so paid or made before or after any
Default has occurred; provided, however, that upon the occurrence and during the
continuance of a Default, the Bank shall be entitled to receive and deposit as
Collateral all cash dividends into the Collateral Account for so long as such
Default continues.  Any such dividends or distributions on account of Pledged
Securities shall, if received by the Borrower, be received in trust for the
benefit of the Bank, be segregated from the other property or funds of the
Borrower, and be forthwith delivered to the Bank as Collateral in the same form
as so received (with any necessary endorsement).

                        SECTION 10.  General Authority.

     The Borrower hereby irrevocably appoints the Bank its true and lawful
attorney, with full power of substitution, in the name of the Borrower, for the
sole use and benefit of the Bank and the holders of the Secured Obligations, but
at the Borrower's expense, to the extent permitted by law to exercise, at any
time and from time to time, all or any of the following powers with respect to
all or any of the Collateral:

     (a)  to take such reasonable action as the Bank deems necessary to protect
or preserve the Collateral and to realize upon the Collateral in accordance with
this Pledge Agreement;

     (b)  if a Default shall have occurred and be continuing, to give notice
thereof to the Borrower, whereupon (i) funds on deposit in the Collateral
Account shall not be made available to the Borrower and (ii) the Bank may direct
the investment and reinvestment of all funds on deposit in the Collateral
Account pending application in accordance with Section 12 in Qualified
Investments; and

     (c)  so long as an Event of Default shall have occurred and be continuing:

               (i)  to demand, sue for, collect, receive and give acquittance
          for any and all monies due or to become due upon or by virtue of the
          Collateral,

               (ii) to settle, compromise, compound, prosecute or defend any
          action or proceeding with respect thereto, and

               (iii)     to sell, transfer, assign or otherwise deal in or with
          the same or the proceeds thereof in accordance with Section 11.

                  SECTION 11.  Remedies upon Event of Default

     (a)  If any Event of Default shall have occurred and be continuing, the
Bank may exercise all the rights of a secured party under the UCC (whether or
not in effect in the jurisdiction where such rights are exercised) and, in
addition, the Bank may without being required to give any notice, except as
herein provided or as may be required by mandatory provisions of law, (i) apply
the cash, if any, then held as Collateral as specified in Section 12 and (ii) if
there shall be no such cash or if such cash shall be insufficient to pay all the
Secured Obligations in full, sell the Collateral or any part thereof at public
or private sale or at any broker's board or on any securities exchange, for
cash, upon credit or for future delivery, and (subject to the requirements of
the UCC) at such price or prices as the Bank may deem satisfactory. The Bank may
be the purchaser of any or all of the Collateral so sold at any public sale (or,
if the Collateral is of a type customarily sold in a recognized market or is of
a type which is the subject of a widely distributed standard price quotations,
at any private sale) and thereafter hold the same, absolutely, free from any
right or claim of whatsoever kind.  The Bank is authorized in connection with
any such sale (i) to restrict the prospective bidders on or purchasers of any of
the Collateral to a limited number of sophisticated investors who will represent
and agree that they are purchasing for their own account for investment and not
with a view to the distribution or sale of any of such Collateral, (ii) to
cause, if applicable, to be placed on certificates for any or all of the Pledged
Securities a legend to the effect that such security has not been registered
under the Securities Act of 1933 ("Securities Act") and may not be disposed of
in violation of the provisions of the Securities Act, and (iii) to impose such
other limitations or conditions in connection with any such sale as the Bank
reasonably deems necessary or advisable in order to comply with the Securities
Act or any other applicable law or regulation.  The Borrower agrees that it will
execute and deliver such documents and take such other reasonable action as the
Bank deems necessary or advisable in order that any such sale may be made in
compliance with law.  Upon any such sale the Bank shall have the right to
deliver, assign and transfer to the purchaser thereof the Collateral so sold.
Each purchaser at any such sale shall hold the Collateral so sold to it
absolutely, free from any claim or right of whatsoever kind, including any
equity or right of redemption of the Borrower which, to the extent permitted by
law, hereby specifically waives all rights of redemption, stay or appraisal
which it has or may have under any law now existing or hereafter adopted.  The
Bank shall give the Borrower not less than ten days' prior written notice of the
time and place of any sale or other intended disposition of any of the
Collateral unless the Collateral threatens to decline speedily in value.  The
Bank and the Borrower agree that such notice constitutes "reasonable
notification" within the meaning of UCC Section 9-504(3).  Such notice (if any
is required) shall (i) in the case of a public sale, state the time and place
fixed for such sale, (ii) in the case of sale at a broker's board or on a
securities exchange, state the board or exchange at which such sale is to be
made and the day on which the Collateral, or the portion thereof so being sold,
will first be offered to sale at such board or exchange, and (iii) in the case
of a private sale, state the day after which such sale may be consummated.  Any
such public sale shall be held at such time or times within ordinary business
hours and at such place or places as the Bank shall deem to be commercially
reasonably, provided that the Bank shall not be obligated to make any such sale
pursuant to any such notice.  The Bank may, without notice or publication,
adjourn any public or private sale or cause the same to be adjourned from time
to time by announcement at the time and place fixed for the sale, and such sale
may be made at any time or place to which the same may be so adjourned.  If all
or any part of the Collateral is sold on credit or for future delivery, the
Collateral so sold may be retained by the Bank until the selling price is paid
by the purchaser thereof, but the Bank shall not incur any liability in case of
the failure of such purchaser to take up and pay for the Collateral so sold and,
in case of any such failure, such Collateral may again be sold upon like notice.
The Bank, instead of exercising the power of sale herein conferred upon it, may
proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court of courts of competent jurisdiction.

     (b)  If the Bank shall determine to exercise its right to sell all or any
of the Pledged Securities pursuant to Rule 144 of the General Rules and
Regulations of the Securities Act ("Rule 144"), at the request of the Bank, the
Borrower shall exercise reasonable best efforts to cause each issuer of any such
Pledged Securities to file, on a timely basis, all annual quarterly and other
reports required to be filed by it under Sections 13 and 15(d) of the Exchange
Act, and the rules and regulations of the SEC thereunder, as amended from time
to time.  In addition, at the request of the Bank, the Borrower shall reasonable
exercise best efforts to cause each issuer of Pledged Securities to cooperate
with the Bank so as to enable such sales to be made in accordance with
applicable laws, rules, and regulations and the requirements of the broker
through which the sales are proposed to be executed, and shall, upon request and
assuming that the requirements of Rule 144 have been complied with, furnish at
the Borrower's expense an opinion of counsel to such issuer of Pledged
Securities that the proposed sale is in compliance with Rule 144.

     (c)  For the purpose of enforcing any and all rights and remedies under
this Pledge Agreement the Bank may (i) require the Borrower to, and the Borrower
agrees that it will, at its expense and upon the request of the Bank, forthwith
assemble all or any part of the Collateral not held by the Bank or an agent as
directed by the Bank and make it available at a place designated by the Bank
which is, in its opinion, reasonably convenient to the Collateral and the
Borrower, whether at the premises of the Borrower or otherwise, (ii) to the
extent permitted by applicable law, enter, with or without process of law and
without breach of the peace, any premises where any of such Collateral is or may
be located, and without charge or liability to it seize and remove such
Collateral from such premises, and (iii) have access to and use the Borrower's
books and records relating to such Collateral.

                     SECTION 12.  Application of Proceeds.

     The proceeds of any sale of, or other realization upon, all or any part of
the Collateral shall be applied by the Bank in the following order of
priorities:

          first, to payment of the expenses of such sale or other realization,
     including reasonable compensation to the Bank, and its agents and counsel,
     and all reasonable expenses, liabilities and advances incurred or made by
     the Bank in connection therewith, and any other unreimbursed reasonable
     expenses or other reasonable amounts for which the Bank is to be reimbursed
     pursuant to Section 13 hereof or is to be reimbursed pursuant to the Credit
     Agreement;

          second, to the ratable payment of accrued but unpaid interest and any
     accrued but unpaid fees constituting part of the Secured Obligations in
     accordance with the terms of the Credit Agreement;

          third, to the ratable payment of unpaid principal of the Secured
     Obligations;

          fourth, to the ratable payment of all other Secured Obligations, until
     all Secured Obligations (including without limitation all reasonable legal
     fees and expenses payable by the Borrower pursuant to the terms of the
     Credit Agreement) shall have been paid in full; and

          finally, to payment to the Borrower or its successors or assigns, or
     as a court of competent jurisdiction may direct, of any surplus then
     remaining from such proceeds.

                             SECTION 13.  Expenses.

     The Borrower will forthwith upon demand pay to the Bank:

     (a)  the amount of any taxes which the Bank may have been required to pay
by reason of the security interests granted hereby (including any applicable
transfer taxes) or to free any of the Collateral from any Lien thereon, and

     (b)  the amount of any and all reasonable out-of-pocket expenses, including
the reasonable fees and disbursements of counsel or any other agents or experts
which the Bank may incur in connection with (i) the administration of this
Pledge Agreement, (ii) the collection, sale or other disposition of any of the
Collateral, (iii) the exercise by the Bank of any of the rights conferred upon
it hereunder or (iv) any default on the part of the Borrower hereunder.

     SECTION 14.  Termination of Security Interests; Release of Collateral.

     Upon the repayment in full of all Secured Obligations and the termination
of the Commitment under the Credit Agreement, the security interests granted
hereby shall terminate and all rights to the Collateral shall revert to the
Borrower, and the Bank will promptly execute and deliver to the Borrower such
documents as the Borrower shall reasonably request to evidence such termination.

                             SECTION 15.  Notices.

     All notices, communications and distributions hereunder shall be given or
made to the parties hereto in the manner and at the locations set forth in the
Credit Agreement or at such other address or telex number as the addressee may
hereafter specify for the purpose of giving notice.

                 SECTION 16.  Waivers, Non-Exclusive Remedies.

     No failure on the part of the Bank to exercise, and no delay in exercising
and no course of dealing with respect to, any right under this Pledge Agreement
or any other Credit Document shall operate as a waiver thereof; nor shall any
single or partial exercise by the Bank of any right under this Pledge Agreement
preclude any other or further exercise thereof or the exercise of any other
right.  The rights and remedies in the Credit Documents are cumulative and are
not exclusive of any other remedies provided by law.

                      SECTION 17.  Successors and Assigns.

     This Pledge Agreement is for the benefit of the Bank and its successors and
assigns, and in the event of an assignment of all or any of the Secured
Obligations, the rights hereunder, to the extent applicable to the indebtedness
so assigned, may be transferred with such indebtedness. The Bank agrees to give
the Borrower written notice of any such assignment.  This Pledge Agreement shall
be binding on the Borrower and its successors and assigns.

                        SECTION 18.  Changes in Writing.

     Neither this Pledge Agreement nor any provision hereof may be changed,
waived, discharged or terminated orally, but only by a statement in writing
signed by the party against which enforcement of the change, waiver, discharge
or termination is sought.

                          SECTION 19.  Choice of Law.

     This Pledge Agreement shall be construed in accordance with and governed by
the laws of the State of Texas, except as otherwise required by mandatory
provisions of law and except to the extent that remedies provided by the laws of
any jurisdiction other than Texas are governed by the laws of such jurisdiction.

                           SECTION 20.  Severability.

     If any provision hereof is invalid and unenforceable in any jurisdiction,
then, to the fullest extent permitted by law, (a) the other provisions hereof
shall remain in full force and effect in such jurisdiction and  shall be
liberally construed in favor of the Bank in order to carry out the intentions of
the parties hereto as nearly as may be possible; and (b) the invalidity or
unenforceability of an provisions hereof in any jurisdiction shall not affect
the validity or enforceability of such provision in any other jurisdiction.

                       FORM OF BORROWER'S COUNSEL OPINION


                                November 5, 1997




Societe Generale, Southwest Agency
1111 Bagby, Suite 2020
Houston, Texas 77002

Ladies and Gentlemen:

I am the general counsel for Contran Corporation, a Delaware corporation (the
"Borrower"),  and I have acted as counsel to the Borrower in connection with (i)
the Credit Agreement dated as of November 4, 1997 (the "Credit Agreement")
between the Borrower and Societe Generale, Southwest Agency (the "Bank") and
(ii) the other Loan Documents (as defined in the Credit Agreement) to which the
Borrower is a party.  I have been requested to render this opinion pursuant to
Section 4.1(e) of the Credit Agreement.  Capitalized terms not otherwise defined
in this opinion shall have the meanings assigned to them in the Credit
Agreement.

In connection with this opinion letter, I have (a) examined copies of the Credit
Agreement, the Note, and the Pledge Agreement (collectively, the "Documents"),
(b) examined and relied upon the originals, or copies certified or otherwise
identified to my satisfaction, of such corporate documents and records of the
Borrower, and (c) received such information from officers and representatives of
the Borrower and the Subsidiaries as I have deemed necessary or appropriate to
enable us to give the opinions expressed below.  I have also examined such other
documents as I have deemed necessary or appropriate to enable me to give the
opinions expressed below, and we have relied without independent investigation
on certificates of public officials and on certificates of officers of the
Borrower as to certain factual matters.

In rendering my opinion, I have assumed (a) the genuineness of all signatures of
the individuals signing all documents in connection with which this opinion is
rendered on behalf of the parties thereto (other than the signatures of the
individuals signing on behalf of the Borrower), (b) the authenticity of all
documents submitted to me as originals, (c) the conformity to authentic original
documents of all documents submitted to me as certified, conformed, or
photostatic copies, and (d) the due authorization, execution, and delivery of
all Credit Documents by the parties thereto other than the Borrower.

Based on the foregoing, and subject to further assumptions, qualifications, and
limitations set forth below, we are of the opinion that:

     1.   The Borrower (a) is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware, (b) has the
corporate power and authority to own its assets and to transact its business as
now being conducted, and (c) is duly qualified to do business in all
jurisdictions in which the nature of the business conducted by it makes such
qualification necessary and where failure to qualify could cause a Material
Adverse Change.

     2.   Keystone (a) is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware, (b) has the corporate
power and authority to own its assets and to transact its business as now being
conducted, and (c) is duly qualified to do business in all jurisdictions in
which the nature of the business conducted by it makes such qualification
necessary and where failure to qualify could cause a Material Adverse Change.

     3.   (a) The execution, delivery or performance by the Borrower of each of
the  Documents, (b) the granting of the Liens provided for in the Pledge
Agreement, and (c) the borrowing of advances by the Borrower, and the issuance
of Letters of Credit for the account of the Borrower under the Credit Agreement
(i) have been duly authorized by all necessary corporate action, (ii) do not and
will not violate any provision of any material law, statute, rule or regulation
applicable to the Borrower in effect on the date hereof or any provision of the
charter or bylaws of the Borrower as in effect on the date hereof, (iii) do not
and will not violate, to the best of my knowledge, any order, writ, injunction
or decree of any court or governmental instrumentality applicable to the
Borrower, or (iv) result in the breach of, or constitute a default or require a
consent under, or (except for the Liens created pursuant to the Pledge
Agreement) result in the creation of any Lien upon any of the properties,
revenues or assets of the Borrower pursuant to any indenture, mortgage, deed of
trust, credit agreement, loan agreement or any other material agreement,
contract, instrument or other agreement know to me after due inquiry to which
the Borrower or its properties may be bound.

     4.   Each of the Documents constitutes a legal, valid and binding
obligation of the Borrower, enforceable in accordance with their respective
terms, except as such enforceability may be limited by (a) bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement or creditors' rights, and (b) the application of general principles
of equity (regardless of whether such enforceability is considered in a
proceeding in equity or at law).

     5.   No authorizations, approvals or consents of, or filings or
registrations with, any governmental or regulatory authority or agency are
necessary in connection with (a) the participation by the Borrower in the
transactions contemplated by the Credit Agreement or the other Documents and the
execution, delivery, or performance by the Borrower of the Documents or (b) the
grant of the Liens provided for in the Pledge Agreement and the validity,
perfection and enforceability thereof.

     6.   No authorizations, approvals or consents of, or filings or
registrations with, any governmental or regulatory authority or agency are
necessary in connection with the validity of the execution and delivery of any
of the Documents by the Borrower except such  consents, approvals, exemptions,
waivers, licenses, or other authorizations, actions, filings or registrations as
(i) have been obtained, completed or made, (ii) are of a routine or
administrative nature or (ii) to which the failure to obtain or make could not
reasonably be expected to cause a Material Adverse Change.

     7.   To my knowledge after due inquiry, there are no legal or arbitral
proceedings, and no proceedings by or before any governmental or regulatory
authority or agency, pending or threatened against or affecting the Borrower or
properties or rights of the Borrower which, if adversely determined, (a) could
cause a Material Adverse Change, or (b) could impair the value of the security
granted to the Bank pursuant to the Pledge Agreement.

     8.   The Pledge Agreement creates as security for the Indebtedness in favor
of the Bank a valid security interest enforceable against the Borrower in all
right, title, and interest of the Borrower in the Pledged Securities (as defined
in the Pledge Agreement) to which Article 9 of the Uniform Commercial Code in
effect in the State of Texas ("U.C.C.") is applicable, assuming the Bank takes
and retain possession of the Pledged Securities, and no filing or recording is
necessary to perfect the Bank's security interest in such Pledged Securities.
Assuming the Bank is a "bona fide purchaser" (as defined in Section 8-302 of the
U.C.C.) of the Pledged Securities and assuming the Bank acquired its interest in
the Pledged Securities in good faith and without notice of any adverse claims
and that each Pledged Securities is either in bearer form or in registered form,
issued or endorsed in the name of the Bank or in blank, the Bank will acquire a
security interest in the Pledged Securities that is prior to any other security
interest therein under the U.C.C.

     9.   No other taxes and governmental fees and charges are required by any
Governmental Authority in connection with (a) the creation or perfection of the
liens purported to be created by the Pledge Agreement, (b) the execution and
delivery of the Documents, or (c) the obtaining of credit under the Credit
Agreement.

     10.  As of the date of this opinion, [                ] Keystone Shares are
                                           ----------------
authorized and [               ] Keystone Shares are issued and outstanding.
                ---------------
The Borrower beneficially owns a total of [               ] Keystone Shares.
                                           ---------------
Except as set forth on Annex A hereto,  (i) there are no outstanding
subscriptions, warrants, options, calls or commitments of any character relating
to or entitling any Person to purchase or otherwise acquire any capital stock of
Keystone, (ii) there are no obligations or securities convertible into or
exchangeable for shares of any capital stock of Keystone or any commitments of
any character relating to or entitling any Person to purchase or otherwise
acquire any such obligations or securities, and (iii) there are no preemptive or
similar rights to subscribe for or to purchase any capital stock of Keystone.

     11.  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.  The making of the Advances and the
application of the proceeds thereof by the Borrower, and the issuance of the
Letters of Credit as provided in the Credit Agreement do not violate Regulations
G, T, U or X of the Board of Governors of the Federal Reserve System.

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

     13.  The Borrower is not a "holding company" or an "affiliate" of a
"holding company" or a "subsidiary company" of a "holding company," within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

     The foregoing opinions are, with your concurrence, predicated upon and
qualified in their entirety by the following:

     This opinion letter is solely for your benefit and the benefit of your
counsel and may not be relied upon by any Person other than you and your
counsel.

                                    Very truly yours,
