                                TO SCHEDULE 13D

     This statement on Schedule 13D is hereby amended and restated in its
entirety as set forth below, except for Item 3, which is amended but not
restated in its entirety (collectively, this "Statement").

Item 1.   Security and Issuer

     This Statement relates to the common stock, $0.01 par value per share (the
"Shares"), of Valhi, Inc., a Delaware corporation (the "Company").  The
principal executive offices of the Company are located at Three Lincoln Centre,
5430 LBJ Freeway, Suite 1740, Dallas, Texas   75240.

Item 2.   Identity and Background

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

     VGI, National and Contran are the direct holders of approximately 74.9%,
10.0% and 6.6%, respectively, of the 114,365,404 Shares outstanding as of
February 28, 1997 according to the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 1996 (the "Outstanding Shares"). Together, VGI,
National and Contran may be deemed to control the Company.  National, NOA and
Dixie Holding are the direct holders of approximately 73.3%, 11.4% and 15.3%,
respectively, of the outstanding common stock of VGI.  Together, National, NOA
and Dixie Holding may be deemed to control VGI.  Contran and NOA are the direct
holders of approximately 85.7% and 14.3%, respectively, of the outstanding
common stock of National and together may be deemed to control National.
Contran and Southwest are the direct holders of approximately 49.9% and 50.1%,
respectively, of the outstanding common stock of NOA and together may be deemed
to control NOA. Dixie Rice is the holder of 100% of the outstanding common stock
of Dixie Holding and may be deemed to control Dixie Holding.  Contran is the
direct holder of approximately 88.7% and 54.3% of the outstanding common stock
of Southwest and Dixie Rice, respectively, and may be deemed to control
Southwest and Dixie Rice.

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

     Substantially all of Contran's outstanding voting stock is held by two
trusts, the Harold C. Simmons Family Trust No. 1 dated January 1, 1964 and the
Harold C. Simmons Family Trust No. 2 dated January 1, 1964 (together, the
"Trusts"), established for the benefit of Mr. Simmons' children and
grandchildren, of which Mr. Simmons is the sole trustee.  As 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.

     By virtue of the holding of the offices, the stock ownership and his
service as trustee, all as described above, (a) Mr. Simmons may be deemed to
control such entities and (b) Mr. Simmons and certain of such entities may be
deemed to possess indirect beneficial ownership of Shares directly held by
certain of such other entities.  However, Mr. Simmons disclaims such beneficial
ownership of the Shares beneficially owned, directly or indirectly, by any of
such entities.

     The Contran Deferred Compensation Trust No. 2 (the "CDCT No. 2") directly
holds approximately 0.2% of the Outstanding Shares.  Contran contributed to the
CDCT No. 2 the 279,000 Shares directly held by the CDCT No. 2 on November 15,
1995. Contran established the CDCT No. 2 pursuant to an agreement (the "Trust
Agreement"), dated as of October 1, 1995, between Contran and NationsBank of
Texas, N.A., a national banking association ("NationsBank").   NationsBank
serves as the trustee of the CDCT No. 2 (the "Trustee").  The CDCT No. 2 was
established in connection with the Amended Deferred Compensation Agreement,
dated as of October 1, 1995, between Contran and Harold C. Simmons. Pursuant to
the Trust Agreement, Contran retains the right to vote the Shares held by the
CDCT No. 2.  Except to fund withholding obligations with respect to payments to
Mr. Simmons, the Trustee may not sell the Shares without Contran's consent.
Contran retains the right at anytime, in its sole discretion, to substitute
assets of equal fair market value for any Shares held by the CDCT No. 2.  The
foregoing summary of the Trust Agreement is qualified in its entirety by
reference to Exhibits 13 and 14 to this Statement, which are incorporated herein
by this reference.  As a result of the relationship between Contran and the CDCT
No. 2, Contran (i) retains sole power to vote the Shares that Contran will
contribute to the CDCT No. 2, (ii) shares dispositive power with the Trustee
over such Shares and (iii) may be deemed the indirect beneficial owner of such
Shares.

     The Combined Master Retirement Trust (the "CMRT") directly holds
approximately 0.1% of the Outstanding Shares.  The CMRT is a trust formed by the
Company to permit the collective investment by trusts that maintain the assets
of certain employee benefit plans adopted by the Company and related companies.
 Mr. Simmons is sole trustee of the CMRT and 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 the Shares held by the CMRT, except to the
extent of his vested beneficial interest therein.
     Harold C. Simmons' spouse is the direct beneficial owner of 77,000 Shares,
or approximately 0.1% of the Outstanding Shares.  Mr. Simmons may be deemed to
share indirect beneficial ownership of such Shares.  Mr. Simmons disclaims all
such beneficial ownership.

     The Reporting Persons understand that NL Industries, Inc. ("NL") and
Valmont Insurance Company ("Valmont") directly held 1,186,200 Shares and
1,000,000 Shares, respectively.  The Company and Tremont Corporation ("Tremont")

     B.   Additional References.

          1.   Accounting Terms.  Accounting terms which are not specifically
               defined in the Loan Documents will be defined or interpreted and
               all reporting practices will be performed, in accordance with
               generally accepted accounting principles ("GAAP") unless the Bank
               Group has given its prior written consent to a different
               accounting definition, interpretation or practice.  Without
               thereby limiting the generality of the foregoing, all financial
               statements and calculations which are based on financial
               condition or results of operations as of specific dates or for
               specific periods (including compliance with financial covenants)
               will be calculated on a consolidated basis unless otherwise
               specified. Whenever any Loan Document calls for a payment to be
               made or an event to occur annually or quarterly, the reference is
               to Contran's fiscal year and fiscal quarter. The term "financial
               statements" means balance sheets and statements of income and
               cash flows prepared in reasonable detail, on a comparative basis,
               and in accordance with GAAP for the interim (quarterly)
               accounting periods and balance sheets and statements of income,
               cash flows, and equity, and related footnotes, for the annual
               accounting periods.

          2.   Legal Terms.  The definitions and substantive terms of the
               Uniform Commercial Code, the Uniform Fraudulent Transfer Act, and
               the Bankruptcy Code will be used as additional aids to
               construction of the Loan Documents before resort to any other
               source. The word "execute" means to subscribe and deliver a
               document.  The term "investment security" means the obligation of
               an issuer, or a share, participation, or other interest in an
               issuer or in property or an enterprise of an issuer, and any
               related certificate and entitlement, including a warrant,
               dividend, or other distribution in respect thereof.

          3.   Date/Time.  Whenever a date or time is specified in the Loan
               Documents, it means such date or time in Portland, Oregon.

          4.   Schedules/Exhibits.  The schedules and exhibits, if any, that are
               attached to this Agreement incorporated into this Agreement by
               this reference.

          5.   Gender; Number.  The Loan Documents are intended to be gender
               neutral and the neuter pronoun can refer not only to an
               organization but also to an individual.  Use of the singular can
               include the plural and vice versa.  Where the singular refers to
               several persons, the liability of such persons is joint and
               several.

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

          7.   Captions.  Captions and headings are merely for convenience and
               substantively are not a part of the Loan Documents.

          8.   Governing Law.  Construction, performance, and enforcement of the
               Loan Documents will be governed by the substantive provisions
               (i.e., without regard to the rules for conflict of laws) of
               Oregon law, but if the Bank Group has greater rights or remedies
               under federal law, then such rights and remedies under federal
               law also will be available to the Bank.

          9.   Complete Agreement.  The Loan Documents are the complete, final,
               and exclusive agreement of the parties.  No term or condition can
               or will be explained, supplement, waived, or modified by conduct
               or oral agreement either before, at, or after signing and
               delivery of the Loan Documents.

               to make Advances and/or extend credit (all such Advances and/or
               extensions of credit at substantially the same time being an
               "Advance") to the Contran Companies for the Allowed Uses until
               the Expiry Date as long as at the time of such Advance (a)
               Contran is not in Default or Prospective Default under the Loan
               Documents, (b) the aggregate principal amount of all outstanding
               Advances and the requested Advance does not exceed the Maximum
               Availability, and (c) the LTV after such Advance will not exceed
               40%.

          2.   Revolving Nature.  The commitments of the Bank Group are
               revolving in nature so the Contran Companies may borrow and repay
               at any time and from time to time without penalty or premium
               (except for breakage charges collectible in connection with full
               or partial prepayment of LIBOR Advances) subject to the terms and
               conditions of the Loan Documents.  LIBOR Advances mature and must
               be repaid or renewed at a new LIBOR or at the Prime Rate at the
               end of the Interest Period applicable thereto.  Prime Rate
               Advances mature and must be repaid on the Expiry Date.

          3.   Notice of Borrowing.  In order to borrow (obtain a LIBOR Advance
               or a Prime Rate Advance), convert a Prime Rate Advance to a LIBOR
               Advance or vice versa, or replace an LIBOR Advance with another
               new LIBOR Advance at the end of an Interest Period, Contran must
               submit a Notice of Borrowing to the Agent through an authorized
               representative (a) not later than 10 a.m. on the date of any
               requested Prime Rate Advance and (b) not later than 9 a.m. on the
               third Banking Day before the effective date of a LIBOR Advance,
               unless the Advance is requested orally and the Agent grants the
               request, in which case either the Advance will be repaid or a
               Notice of Borrowing will be submitted to the Agent in writing
               within 48 hours following the oral request (including any
               breakage charge related thereto).

               The Notice of Borrowing will specify the date when the Advance is
               to be funded, converted, or renewed, the amount thereof, the
               applicable interest rate and, if the LIBOR has been selected, the
               Interest Period. Each Notice of Borrowing and oral request will
               be irrevocable and the Agent and the Bank Group will be entitled
               to procure funds in reliance on such Notice of Borrowing and oral
               request; provided, however, that Contran may withdraw any Notice
               of Borrowing at any time prior to the funding of such Advance as
               long as Contran pays all reasonable direct costs and expenses
               (including breakage charges) incurred by any member(s) of the
               Bank Group in reliance on such Notice of Borrowing. No LIBOR
               Interest Period may be selected that extends beyond the Expiry
               Date.  The Prime Rate will be applicable to each Advance unless
               Contran has properly selected the LIBOR.

          4.   Disbursement of Proceeds.   All Advances will be funded by wiring
               the proceeds thereof into Contran's general corporate checking
               account.

          5.   Interest Rates.  The rates of interest payable by Contran will be
               (a) the Prime Rate on each Prime Rate Advance and (b) if selected
               by Contran, the LIBOR plus a margin of 1.75% (175 basis points)
               per annum for on each LIBOR Advance in the minimum amount of
               $1,000,000 and increments of $500,000 in excess of the minimum
               amount.

          6.   Principal Repayment.   Contran will repay the Advances on or
               before the Expiry Date.

     B.   General Matters.

          1.   Medium. All Advances will be made by, and all payments will be
               made to, the Bank Group in immediately available U.S. dollars.

          2.   Interest Payments.  Interest on Prime Rate Advances is due
               monthly in arrears.  Interest on LIBOR Advances is due in arrears
               at the end of the Interest Period and, in the event of any 6-
               month LIBOR Interest Period, at the end of the first 90 days of
               the Interest Period.

          3.   Payments.  Any payment received by the Agent after noon will be
               deemed to have been made on the next following Banking Day and
               interest will accrue to that day.  In the event that the date
               specified for payment is not a Banking Day, then interest will
               accrue to and the payment will be made on the next following
               Banking Day; provided, however, that if the next Banking Day
               following the end of an Interest Period for a LIBOR Advance is in
               the following calendar month, then payment  or renewal of the
               LIBOR Advance will be due on the last Banking Day which precedes
               the end of that Interest Period.  All payments will be applied,
               to the extent amounts are due, first to costs (including breakage
               charges), then to fees, then to accrued interest, and finally to
               principal.

          4.   Breakage Charge.  Contran may prepay a LIBOR Advance only upon
               three days' advance written notice and upon payment of the
               breakage charge specified in the Note.

          5.   Terminating LIBOR.  The Bank Group is offering the LIBOR to
               Contran on the assumption that there will continue to be an
               active interbank market in Eurodollars.  If that market ceases to
               exist or if it otherwise becomes illegal or impractical for any
               member of the Bank Group to fund an Advance with reference to
               this source of funds, then the Bank Group member(s) so affected
               will give notice of such illegality or impracticality to Contran
               and any future loan from those members of the Bank Group will be
               at the Prime Rate.

          6.   Increased Costs.  If any member of the Bank Group is required to
               increase its reserves, insurance premiums, or regulatory capital
               or to pay additional taxes (other than income taxes) in order to
               make Advances to Contran because of the future enactment,
               promulgation, or amendment of any statute, regulation, or order
               by a government or governmental subdivision or agency, then
               Contran will reimburse such member(s) of the Bank Group on demand
               for all such increased costs as estimated in writing with
               reasonable particularity by such member.

          7.   Notes; Promise of Repayment.  Contran promises and agrees to
               issue a note to each member of the Bank Group in the amount of
               such member's commitment and to repay all Advances, plus
               interest, fees, costs and expenses, to the order of each member
               of the Bank Group in accordance with such member's Percentage
               Interest.

          8.   Guaranty; Promise of Repayment.  The Contran Affiliates jointly
               and severally promise and agree to issue the guaranty to each
               member of the Bank Group and to repay each Bank Group member's
               Percentage Interest of all Advances, plus interest, fees, costs
               and expenses, to such member's order in accordance with the terms
               hereof and of the note.

          9.   Nature of Liability.  Contran, VGI, and NCL are jointly,
               severally, and primarily liable for performance of the
               Obligations.

          10.  Maintenance of Loan-to-Value Ratio: Mandatory Prepayment or
               Pledge of Additional Pledged Securities.   If the outstanding
               principal balance of the Advances at any time results in an LTV
               of more than 50%, the Contran Affiliates immediately will either
               (a) make a prepayment of principal so as to reduce the LTV to 50%
               or less and/or (b) pledge additional investment securities in
               quality and quantity reasonably acceptable to the Bank Group so
               as to reduce the LTV to 50% or less.  For the purposes of this
               paragraph, the Bank Group acknowledges and agrees that the
               Contran Companies always may pledge additional shares of Valhi
               common stock owned by a Contran Company in order to meet the LTV
               requirement.  Prepayments required under this section will be
               applied first to Prime Rate Advances, because such Advances may
               be prepaid without payment of the breakage charge, and then to
               LIBOR Advances in an order which first pays the LIBOR Advance(s)
               with the shortest remaining time until maturity, then the next
               shortest period, etc.  If additional investment securities are
               pledged and the value of the pledged securities later increases,
               the Agent will, upon the written request of the Contran
               Affiliates, return to the Contran Affiliates any of the
               additional pledged securities (but not the Valhi or Tremont
               shares pledged initially) which are not then necessary to
               maintain the LTV at 50% or less.



          11.  Waiver; Forbearance.  Each Contran Affiliate waives acceptance,
               presentment (including notice of dishonor) and all claims,
               offsets, defenses, and counterclaims based on suretyship or
               impairment of collateral.  Without limiting the foregoing, each
               Contran Affiliate consents to extension of due dates, material
               modifications, and impairment of contribution rights and the
               value of interests in collateral without prior notice or demand.

III. CONDITIONS PRECEDENT.

     A.   Conditions to First Borrowing.  The following are conditions precedent
          which must be satisfied by the Contran Affiliates or waived by the
          Bank prior to the first Advance:

          1.   Loan Documents.  Contran has duly executed (signed, acknowledged
               where appropriate, and delivered) the Loan Documents;

          2.   Guaranties.  The Contran Affiliates have executed the Guaranties
               and the Security Documents;

          3.   Corporate Documents.  Each Contran Company has delivered
               certified true copies of currently effective (a) articles of
               incorporation, bylaws, and similar governance documents (its
               "organization documents"), (b) resolutions of its board of
               directors authorizing it to execute each of the Loan Documents to
               which such organization is a party and to perform the
               Obligations, and specifying the representative(s) who will
               execute the Loan Documents on its behalf (and, for Contran, who
               may request Advances) (its "borrowing resolutions"), and (c) an
               incumbency certificate executed by its corporate secretary
               containing specimen signatures of the representatives who will
               execute the Loan Documents and, in the case of Contran, request
               Advances (its "incumbency certificate");

          4.   Representations and Warranties.  The representations and
               warranties made by the Contran Affiliates in the Loan Documents
               are true, complete and correct in all material respects as of the
               date upon which the Loan Documents are executed and the date upon
               which the first loan is requested and a duly authorized
               representative of each Contran Affiliate has executed a
               certificate dated as of the date of the first Advance certifying
               the continued accuracy and completeness of the representations
               and warranties;

          5.   Legal Opinion.  Contran's general counsel has rendered an opinion
               to the Bank Group opining that as of the date of the Loan
               Documents (a) each Contran Company is an existing Delaware
               corporation that has been duly organized, (b) each Contran
               Company has been duly authorized to execute each of the Loan
               Documents to which such organization is a party and to perform
               the Obligations, (c) each of the Loan Documents is the legally
               valid and binding obligation of each Contran Company who is a
               party thereto and is enforceable in accordance with its terms
               except as enforcement may be limited by insolvency or other
               similar laws affecting the rights and remedies of creditors
               generally, general principles of equity, whether applied by a
               court of law or equity, and other generally applicable rules of
               law, and (d) the Security Documents are a form sufficient to
               create a lien on or security interest in all right, title, and
               interest of the Contran Companies in the Pledged Securities;

          6.   Perfection.  The Contran Companies have delivered to the Agent
               possession of the certificates evidencing the investments
               securities which are part of the Pledged Securities with stock
               powers signed in blank and related compliance certificates and
               the Agent has perfected its security interest of the Bank Group
               in any other types or items of the collateral;

          7.   Legal Matters.  All matters pertaining to the Loan Documents and
               the Advances are reasonably satisfactory to the Agent and the
               Agent has received all certificates, insurance policies and
               documents that it reasonably requires to establish compliance
               with the terms and conditions of the Loan Documents.

     B.   Subsequent Advances.  The following are conditions precedent which
          must be satisfied by Contran or waived by the Bank Group prior to any
          Advance subsequent to the first Advance:

          1.   No default.  There is no Default or Prospective Default on the
               date of such Advance after giving effect to such Advance;

          2.   Representations and Warranties.  The representations and
               warranties made by the Contran Companies in the Loan Documents
               continue to be true, complete and correct in all material
               respects; and

          3.   LTV Compliance.  After giving effect to the requested Advance,
               the LTV will be 40% or less.

IV.  REPRESENTATIONS AND WARRANTIES.

     A.   Representations and Warranties.  Each Contran Company represents and
          warrants to the Bank Group that:

          1.   Corporate Organization.  Each Contran Company is a Delaware
               corporation which is duly organized and is duly qualified to
               transact business in all other states and countries where the
               failure to be so qualified would have a material adverse impact
               on its business operations or ownership of property;

          2.   Authorization.  Each Contran Company has been duly authorized to
               execute each of the Loan Documents to which such organization is
               a party and to perform the Obligations;

          3.   Due Execution and Delivery.  Each Loan Document to which such
               organization is a party has been duly executed by a
               representative of such organization who has been duly authorized
               to perform such acts;

          4.   Legally Binding Documents.  Each Loan Document is the legally
               valid and binding obligation of each Contran Company who is a
               party to such document and is enforceable against such
               organization in accordance with its terms except as such
               enforcement may be limited by insolvency or other similar laws
               affecting the rights and remedies of creditors generally, general
               principles of equity whether applied by a court of law or equity,
               and generally applicable rules of law;

          5.   Accurate Financial Statements.  The annual and interim financial
               statements of the Contran Companies furnished to the Bank Group
               present fairly the financial position of such Contran Companies
               as of the date of such financial statements and the results of
               the operations and changes in financial position for the annual
               and interim periods then ending (1);

          6.   No Violations.  Neither the execution of the Loan Documents nor
               the performance of the Obligations by the Contran Companies is
               prohibited by or will subject any Contran Company to any fine,
               penalty or similar sanction under, any statute, regulation, or
               order applicable to such organization;

          7.   No Proceedings.  There are no civil, criminal, or administrative
               proceeding now pending or overtly threatened in writing against
               any Contran Company which has not been disclosed in the audited
               financial statements which have been provided to the Bank or
[FN]
(1)
   The financial statements for VGI and NCL may omit footnote disclosures which
would normally be required under GAAP.
               
               separately in writing and which, if adversely determined, would
               have a material adverse effect on the ability of the Contran
               Companies to repay the Advances and perform their other
               obligations to the Bank Group under the Loan Documents;

          8.   No Breach or default.  No Contran Company is now, or by reason of
               the execution of the Loan Documents or performance of the
               Obligations will be, in breach of or in default under any
               "employee pension benefit plans" or "employee benefit plans" (as
               those terms are defined by Section 3 of the Employee Retirement
               Income Security Act of 1974, as amended) to which such
               organization is a party or sponsor in any material respect or any
               other material agreement, instrument, undertaking, or other
               contract to which such organization is a party or by which its
               property is bound;

          9.   Tax Returns; Taxes.  Each Contran Company has filed all material
               tax returns that it is required by any statute, regulation, or
               order to file and has paid when due all material taxes imposed on
               it or its property;

          10.  Compliance with Law.  Each Contran Company is in compliance in
               all material respects with all statutory laws, regulations, and
               orders that are applicable to such organizations and their
               property specifically including, but not limited to,
               environmental laws;

          11.  Hazardous Material.  To the best knowledge of Contran, there is
               no hazardous material being released, and no hazardous material
               has been released, from or at any real property owned or operated
               by any Contran Company in quantities which would trigger such
               organization's obligation under applicable environmental laws to
               report the existence of such waste or to remove and dispose of
               such waste or to remediate the effects of a prior discharge
               thereof except as disclosed to the Bank in writing before the
               date of the Loan Documents;

          12.  Solvency.  No Contran Company is insolvent or the subject of any
               insolvency proceedings and each Contran Company has capital which
               is reasonably adequate to conduct its business in the manner in
               which it intends to conduct such business;

          13.  Investment Company Act.  No Contran Company (which by definition
               excludes Tremont) is an "investment company" as that term is
               defined by Section 3(a) of the Investment Company Act of 1940;

          14.  No Material Adverse Change.  There has been no material adverse
               change in the business operations, financial position, or cash
               flows of the Contran Companies since the date of the lastest
               annual financial statement provided to the Bank Group before the
               date of this Agreement; and

          15.  Ownership of Pledged Securities.  Each Contran Company owns the
               item or items of Pledged Securities that such organization
               purports to own and such property is free and clear of all liens,
               security interests, and claims except to the extent that a
               security interest is granted to the Bank Group in the Loan
               Documents.

     B.   Reaffirmation.  The Contran Companies will be deemed to reaffirm the
          accuracy and completeness of the foregoing representations and
          warranties each time that an Advance is requested.

V.   COVENANTS.

     A.   Affirmative Covenants.  The Contran Companies promise and agree that
          until the Advances are repaid and all other Obligations are discharged
          by performance, each Contran Company will, unless the Agent otherwise
          consents in writing:

          1.   Preserving Existence.  Preserve its legal status and material
               franchises and pay all material taxes and fees in connection

               or its property specifically including, but not limited to,
               environmental laws, if noncompliance would or is likely to have a
               material adverse effect on the financial condition or business
               prospects of such organization or its ability to perform the
               Obligations;

          3.   Insurance.  Obtain and maintain with responsible carriers or

               damage and such other insurance in such coverage amounts,
               deductibles and terms as may be consistent with industry
               practices and will provide evidence of such insurance and payment
               of premiums to the Agent as and when required by the Agent;

          4.   Payment and Performance of Debts, Liabilities and Obligations.
               Pay and perform when due all material debts and obligations owed
               to all third persons, specifically including, but not limited to,
               its obligations under any "employee pension benefit plans" or
               "employee benefit plans" (as those terms are defined by Section 3
               of the Employee Retirement Income Security Act of 1974, as
               amended) to which such person is a party or sponsor in any
               material respect or any other material agreement, instrument,
               undertaking, or other contract to which such person is a party or
               by which its property is bound;

          5.   Books and Records.  Keep accurate and complete books and records
               relating to the Pledged Securities and its other assets and

          6.   Tax Returns.  File all tax returns required by statute,

               three quarterly reporting periods of each fiscal year, (b)
               audited annual consolidated financial statements of Contran
               within 120 days following the end of each fiscal year,
               accompanied by a copy of an unqualified audit opinion issued by
               certified public accountants reasonably satisfactory to the Bank
               Group and, if issued, copies of such auditor's "management
               letter," and (c) unaudited consolidating financial statements of
               VGI and NCL within 60 days following the end of each of the first
               three quarterly reporting periods and within 120 days of the end
               of each fiscal year, which unaudited consolidating financial
               statements of VGI and NCL may omit all footnote disclosures
               normally required in financial statements prepared in accordance
               with GAAP;

          8.   Auditor Certificates.  Deliver to each member of the Bank Group
               with the audited annual consolidated financial statements of
               Contran the certificate of the auditors addressed to the Agent
               and certifying, based only on review of the annual audited
               financial statements and the Loan Documents, that the auditors
               are not aware of any event of Default or Prospective Default or,
               if such auditors are aware of such event, specifying such events
               with reasonable particularity; provided, however, that in
               connection therewith the auditors shall be under no obligation to
               go beyond the bounds of generally accepted auditing standards for
               the purpose of certifying such compliance or non-compliance;

          9.   Additional Information; Compliance Certificates.  Provide to the
               Agent:

               a)   A Notice of Borrowing when and as Contran requests Advances;

               b)   Such additional information as and when reasonably requested
                    by the Bank Group or the Agent as to the Pledged Securities
                    and the business operations and financial condition of any
                    one or more of the Contran Companies;

                    written notice thereof, a report of each pending and overtly
                    threatened claim, litigation, and governmental proceeding
                    which, if adversely determined, probably would involve an
                    aggregate liability of $5,000,000 or more;

               e)   Quarterly and annual compliance certificates, to accompany
                    the quarterly and annual financial statements, signed by a
                    duly authorized representative of the Contran Companies
                    which either (A) certifies that there is no event of Default
                    or Prospective Default as of the date of the certificate to
                    the knowledge of the representative or (B) specifies with
                    reasonable particularity such events then existing and known
                    to the representative and outlines its plan for cure
                    thereof;

               f)   Copies of any filings or reports that any Contran Company
                    files or makes with any federal or state government
                    department, commission, or agency regulating investment
                    securities as and when such filings or reports are filed or
                    made to such government department, commission, or agency;
                    and

               g)   If Contran becomes aware of any material event of Default or
                    Prospective Default between quarterly and annual reporting
                    dates, written notice of such event of Default or
                    Prospective Default within 10 days after Contran's senior
                    management learns of such event of Default or Prospective
                    Default.

          10.  Inspection Rights.  The Agent will have the right to discuss
               financial statements and other books and records with accounting
               employees and outside accountants of each Contran Company and the
               Contran Companies will ensure that the Agent may exercise and
               enjoy such rights subject to the obligation of the Agent to give
               reasonable advance notice to the Contran Companies under the
               circumstances. The Contran Companies will reimburse the Agent for
               all reasonable costs and expenses incurred by the Agent in
               connection with the foregoing.  All employees and outside
               accountants are hereby authorized to discuss such matters with
               the Agent, to provide such additional books and records and
               information as may be reasonably requested by the Agent in
               connection therewith, and to bill the Contran Companies for such
               services.  The Agent also will give prior notice to the Contran
               Companies of the intention to discuss such matters with the
               outside accountants so as to provide the opportunity to the
               management of the Contran Companies to be present at such
               discussions.

          11.  Contest Rights.  Notwithstanding the foregoing covenants, each
               Contran Company will have the right to contest its obligations
               under statutory laws, regulations, orders, and contracts (other
               than the Obligations) and for payment of taxes as long as (a)
               such contest is started and continued in good faith and by
               appropriate means, (b) adequate reserves are maintained by the
               Contran Company engaging in such contest for performance of the
               obligation in the event of an outcome of such contest that is
               adverse to the Contran Company involved and (c) the Bank Group is
               notified of any such contest where an adverse outcome probably
               would involve a payment of $5,000,000 or more.

     B.   Negative Covenants.  Each Contran Company promises and agrees that
          until the Advances are repaid and all other Obligations have been
          discharged by performance, it will not, unless the Bank Group
          otherwise consents in writing:

          1.   Additional Debt.  Directly or indirectly (by borrowing, deferred
               purchase, guarantee, or otherwise) incur more than $25,000,000 as
               a group in funded debt in excess of that immediately available to
               the Contran Companies on the date of this Agreement except for
               loans occurring in the ordinary course of business from the
               Contran Companies to each  Contran Company and/or Valhi;

          2.   Asset Transfers.  Transfer any material or essential part of or
               interest in their property to any third party except for sales of
               inventory and surplus or obsolete equipment, the collection of
               accounts, and sales and exchanges of other assets in the ordinary
               course of business;

          3.   Transactions with Affiliates.  Engage in any material business
               transaction with any affiliate or other third party on terms less
               favorable to the Contran Company than those which could be
               obtained at the time thereof in arm's-length dealings with a
               nonaffiliated person;

          4.   Business Combinations.  Engage in any merger, acquisition, or
               exchange of equity securities unless the Contran Company is the
               surviving corporation and the Contran Companies continue to be in
               compliance with all of the terms and conditions of the Loan
               Documents; or

          5.   Use of Proceeds.  Use the proceeds of any loan for any purpose
               not permitted by the Loan Documents.

VI.  DEFAULT.

     TIME IS OF THE ESSENCE.  Contran will be in default under the Loan
     Documents if:

     A.   Payment Failure.  The Contran Companies fail to make any payment of
          principal when due or fail to make any payment of interest, fees or
          costs within three Banking Days following the due date;

     B.   LTV Compliance.  The Contran Companies fail to prepay principal or
          pledge additional Pledged Securities within three Banking Days
          following receipt of written notice from the Agent that the LTV
          exceeds 50% if and when required by the Agent under the terms of this
          Agreement.

     C.   Misrepresentation.  Any Contran Company knowingly misrepresents any
          material fact to the Bank Group or the Agent or fails to disclose to
          the Bank Group or the Agent a material fact which is necessary to make
          the facts which have been disclosed not misleading in the
          circumstances under which they are made;

     D.   Affirmative Covenants.  The Contran Companies fail to comply with the
          affirmative covenants contained in any of the Loan Documents within 30
          days following the date such compliance is demanded by the Bank Group
          or, if such compliance cannot be completed within that 30-day period,
          fails to substantially commence compliance within that 30-day period
          and then to complete such compliance as soon as possible thereafter
          but in no event later than 60 days after such compliance is demanded;

     E.   Negative Covenants.  Any Contran Company breaches any negative
          covenant contained in the Loan Documents;

     F.   Debt Default.  Any Contran Company breaches or is in default under any
          agreement, instrument, or similar contractual undertaking for the
          repayment of funded debt in excess of $5,000,000 or does not pay any
          trade account payables which is material or essential to its business,
          other than those where the amount or validity is being contested in
          good faith and by appropriate means, in the ordinary course of
          business;

     G.   Guaranty.  Any Contran Affiliate repudiates, breaches, or is in
          default under the Guaranty or the Security Documents;

     H.   Insolvency.  Any Contran Company becomes insolvent, the subject of any
          voluntary insolvency proceeding or, having become the subject of an
          involuntary insolvency proceeding, fails to have the involuntary
          proceeding dismissed within 90 days of commencement;

     I.   Judgments.  Any Contran Company becomes a judgment debtor for more
          than $5,000,000 if such liability is not either covered by insurance
          or vacated, discharged, stayed, or bonded in connection with an appeal
          within 30 days of entry of the judgment; or

     J.   Change in Control.  Any person or group of persons, other than the
          current holders, hereafter directly or indirectly acquires control of
          any Contran Company and such change in control continues for 60 days.

VII. REMEDIES.

     A.   Suspending Commitment.  The members of the Bank Group may suspend
          their obligations to make Advances to Contran upon the occurrence of a
          Prospective Default or when the LTV is more than 40%.

     B.   Canceling Commitments.  The members of the Bank Group may cancel their
          obligations to makes Advances to Contran and accelerate the due date
          of the Notes (make payment of all principal, interest, fees and costs
          immediately due and payable) without further notice or demand upon the
          occurrence of an event of Default and Contran's failure to cure such
          Default within applicable notice and grace periods.

     C.   Collecting Payments; Order of Exercise of Remedies.  The Bank Group
          may collect the overdue payments or the accelerated balance of the
          Notes at such times and in such order as the Bank Group selects.  All
          rights and remedies provided by law, equity and contract are
          cumulative.

     D.   Consent to Jurisdiction.  Each Contran Company consents to the
          jurisdiction and venue of the circuit court of the state of Oregon for
          Multnomah County (Portland) and of any federal court located in the
          state of Oregon for any proceeding arising out of the Loan Documents,
          including offsets, defenses, and counterclaims arising in contract or
          tort.

     E.   Offset.  Without limiting the generality of the foregoing, each
          Contran Company expressly grants to each member of the Bank Group the
          right to offset the obligations of the Bank Group to the Contran
          Companies against the Obligations without notice or demand upon the
          occurrence and continuance of a Default.

     F.   JURY TRIAL WAIVER.  ON ADVICE OF COUNSEL AND IN LIEU OF AN ARBITRATION
          CLAUSE NORMALLY REQUIRED BY THE AGENT, EACH CONTRAN COMPANY WAIVES
          TRIAL BY JURY IN ANY CONTROVERSY (CLAIM, OFFSET, DEFENSE,
          COUNTERCLAIM, OR THIRD-PARTY CLAIM WHETHER ASSERTED IN TORT OR
          CONTRACT) ARISING OUT OF OR IN ANY WAY RELATED TO CONSTRUCTION,
          PERFORMANCE, AND/OR ENFORCEMENT OF THE LOAN DOCUMENTS.

     G.   Costs.  The prevailing party in the trial or appeal of any civil
          action or other proceeding relating to the Loan Documents (including
          claims and adversary proceedings in the Bankruptcy Court) will be
          entitled to the award of a reasonable attorney fee in addition to
          costs and disbursements.  If the Bank Group uses an attorney to
          enforce performance of the Obligations, the Contran Companies will
          reimburse the Bank Group for such costs reasonably incurred on demand
          whether or not a civil action or other proceeding is commenced.

VIII.INDEMNITY.

     A.   Indemnity.  The Contran Companies promise and agree to indemnify,
          defend and hold harmless each member of the Bank Group from and
          against all claims and causes of action (and any direct and reasonable
          loss, damage, liability, cost, and expense, including penalties,
          damages, liens and reasonable attorney fees and other defense costs
          resulting therefrom) of any kind or nature whatsoever that may be
          imposed on, incurred by, or asserted against any of such member in
          connection with any investigation, litigation, or other proceeding,
          that arises from or relates to the Loan Documents or the failure of
          any of the Contran Companies to perform the Obligations, but the
          Contran Companies will not be responsible for any portion of such
          indemnified claims or causes of action that arise from or relate to
          the negligence or willful misconduct of any member of the Bank Group,
          any controversies or claims among the members of the Bank Group, or
          the failure of a member of the Bank Group to comply with any statute,
          regulation, or order applicable to such indemnified party.

     B.   Durable Nature.  This indemnity will survive the satisfaction or
          discharge of the Advances by payment, bankruptcy discharge, or
          otherwise.

IX.  AGENCY PROVISIONS.

     A.   Authorization and Action.  Each member of the Bank Group hereby
          irrevocably appoints the Agent as its agent for administration of the
          Advances and Obligations and authorizes the Agent to take such action
          and exercise such powers under this Agreement as are granted to the
          Bank Group, subject to the voting/approval provisions of this Article,
          by the terms of this Agreement together with such additional actions
          and powers as are reasonably incidental thereto.  The obligations of
          the Agent are mechanical and administrative in nature.  Accordingly,
          the Agent is not by reason of its role under this Agreement a trustee
          or fiduciary for any member of the Bank Group.  The Agent will have no
          obligations except those expressly stated in this Agreement.  As to
          any matters not expressly provided for in this Agreement (including,
          but not limited to, enforcement or collection of the Notes), the Agent
          will not be required to exercise any discretion or take any action,
          but will be required to act or to refrain from acting upon the
          instructions of the Bank Group Majority, and such instructions will be
          binding on all members of the Bank Group; provided, however, that the
          Agent will not be required to take any action which exposes the Agent
          to personal liability or that is contrary to this Agreement or
          applicable laws, regulations, or orders.

     B.   Liability of the Agent.  The Agent (including its shareholders,
          directors, officers, agents, and employees) will not be liable for any
          action taken or inaction by it under or in connection with this
          Agreement in the absence of its own gross negligence or willful
          misconduct.  Without thereby limiting the foregoing sentence, the
          Agent:

          1.   May treat the payee of a Note as the holder thereof until the
               Agent receives written notice of a transfer thereof signed by
               such payee in a form reasonably satisfactory to the Agent;

          2.   May consult with legal counsel, independent public accountants,
               and other experts selected by it and will not be liable for any
               action taken or inaction by it in good faith in accordance with
               the advice of such counsel, accountants, or experts;

          3.   Makes no warranty or representation to any Bank and will not be
               liable or  responsible for the statements, warranties, or
               representations made by the Contran Companies or any other person
               in connection with this Agreement,

          4.   Will not have any obligation to inquire as to the performance or
               observance of any of the terms, covenants, or conditions of this
               Agreement on the part of the Contran Companies or any other
               person or to inspect any Pledged Securities, books and records,
               or other property of the Contran Companies or any other person;

          5.   Will not be responsible to any member of the Bank Group for the
               due execution, legality, validity, enforceability, genuineness,
               perfection, sufficiency, or value of this Agreement, the Notes,
               or any other certificate, instrument, or document furnished
               pursuant to this Agreement, and

          6.   Will have no liability under this Agreement or otherwise by
               acting upon any notice, consent, certificate, or other
               instrument, document, or other writing (whether personally
               delivered or sent by mail, messenger, telegram, telex, or
               facsimile) believed by the Agent to be genuine and signed by the
               proper person.

     C.   Rights of Agent as a Member of the Bank Group.   With respect to its
          individual commitment, the Advances made by it, and the Note and
          Guaranty issued to it, the Agent will have the same rights, powers,
          and obligations under this Agreement as any other member of the Bank
          Group and may exercise and perform the same as though it were not also
          the Agent.  The Agent and its affiliates may accept deposits from,
          lend money to, act as trustee for, and generally engage in any
          business with or own securities of the Contran Companies as if the
          Agent were not the Agent for the Bank Group and without any obligation
          to account therefor to the Bank Group.

     D.   Independent Credit Decision.  Each member of the Bank Group
          acknowledges that it has made its own credit analysis and decision
          before making its commitment on the basis of such documents and
          information that it deemed appropriate and without reliance on any
          information, analysis, or recommendation made by the Agent.  Each
          member of the Bank Group also acknowledges that it will continue to
          make such independent credit analyses and decisions in taking or not
          taking action under this Agreement.  Except for the notices, reports,
          and other documents and information that the Agent is specifically
          required to furnish to the members of the Bank Group under this
          Agreement, the Agent will have no obligation to provide to the members
          of the Bank Group any additional information concerning the financial
          condition, business operations, or property of the Contran Companies
          that may come into the possession of the Agent or its affiliates.

     E.   Indemnification.  Each member of the Bank Group agrees to indemnify
          and hold harmless the Agent from and against such member's Percentage
          Interest of all claims and causes of action (and any resulting loss,
          damage, liability, cost, and expense, including penalties, damages,
          liens and reasonable attorney fees and other defense costs) of any
          kind or nature whatsoever that (i) may be imposed on, incurred by, or
          asserted against the Agent in any way relating to or arising from this
          Agreement, (ii) are not reimbursed to the Agent by the Contran
          Companies, and (iii) are not the result of the Agent's gross
          negligence or willful misconduct.  Without limiting the generality of
          the foregoing, each member of the Bank Group agrees to reimburse the
          Agent for its Percentage Interest of any reasonable out-of-pocket
          expenses, including reasonable attorney fees, incurred by the Agent in
          connection with the preparation, administration, enforcement, or legal
          advice with respect to rights or duties under, the Loan Documents to
          the extent that such expenses are not reimbursed by the Contran
          Companies.

     F.   Successor Agent.  The Agent may resign at any time by giving at least
          60 days' prior written notice to the Bank Group and to the Contran
          Companies. Upon resignation, the Bank Group Majority will appoint a
          successor Agent.  If no successor Agent has been appointed and
          accepted its appointment within 30 days of receipt of the notice of
          resignation of the Agent, then the Agent may appoint its successor
          which shall be a national bank having combined capital and surplus of
          at least $100 million.  Upon acceptance by the successor of its
          appointment, such successor will succeed to and become vested with all
          of the rights, powers, privileges, and duties of the Agent and the
          retiring or removed Agent will be discharged from its obligations as
          the Agent under this Agreement.

     G.   Sharing of Payments and Recoveries.  If any member of the Bank Group
          obtains any payment (whether voluntary, involuntary, by way of offset,
          or otherwise) on account of the Note held by it and such payment is in
          excess of its Percentage Interest, such member will purchase from the
          other members of the Bank Group such participation in the Notes held
          by them as is necessary to cause such purchasing member of the Bank
          Group to share the excess payment ratably with the other members of
          the Bank Group.  If such member is thereafter required to return all
          or any part of the excess payment, then the purchase of participation
          by such member of the Bank Group will be rescinded to the same extent
          and the purchase price of such participation (or so much thereof as is
          recovered) will be refunded.

     H.   Modifications, Consents, and Waivers.    Except as allowed or limited
          by the remainder of this section, the Bank Group Majority may in
          specific instances modify the terms and conditions of this Agreement,
          grant consents requested by the Contran Companies, waive compliance by
          the Contran Companies with the terms and conditions of this Agreement
          but any such modifications, consent, or waiver must be in writing to
          be effective.

          Notwithstanding any other term or conditions of the Loan Documents, no
          modification, consent, or waiver may, unless such modification,
          consent, waiver, release, or termination is in writing and is signed
          by all members of the Bank Group:

          1.   Waive any of the conditions precedent specified in Article III of
               this Agreement;

          2.   Increase or decrease the individual commitment of any member of
               the Bank Group, or otherwise subject any member of the Bank Group
               to any additional obligations without such bank's consent

          3.   Reduce the amount payable on any Note (including principal,
               interest, or fees);

          4.   Extend the Expiry Date or the Maturity Date;

          5.   Change the definition of "Bank Group Majority" or modify this
               section; or

          6.   Authorize the release or termination of any Guaranty or the
               security interest of the Bank Group in any material or essential
               part of or interest in the Pledged Securities.

     Notwithstanding the foregoing, the Bank Group Majority will have the right
     to authorize the Agent to release parts of and/or interests in Pledged
     Securities from time to time to accommodate ordinary course of business
     transactions by the Contran Companies and the Agent may release additional
     pledged securities as provided in 'II.B.10 of this Agreement as long as the
     LTV is maintained at or above 50%.



X.   MISCELLANEOUS.

     A.   Binding Successors.  The Loan Documents will bind the successors and
          assigns of the Contran Companies and will bind and inure to the
          benefit of the successors and assigns of each member of the Bank Group
          and the Agent.

     B.   Participants and Assignees. Each member of the Bank Group will be
          entitled to sell no more than 75% participation in its percentage
          interest in the Loan Documents (including the Advances made
          thereunder) and will be entitled to propose to the Contran Companies
          partial assignment of its rights and delegation of its duties to no
          more than two financial institutions.  While the Contran Companies
          will have the right prior to a Default or Prospective Default to
          consent to any such assignment and delegation, each Contran Company
          covenants that its consent will not be unreasonably withheld.

          Upon the sale of a participation or a partial assignment, the
          participant or assignee shall be entitled to receive directly from the
          Contran Companies  copies of all reports, certificates and other
          information, including the financial statements, as and when such
          information is provided to the member of the Bank Group participating
          or assigning such interest.

     C.   Non-Waiver.  No term or condition of the Loan Documents shall be
          deemed waived nor shall the grounds for the claim of estoppel be
          established by a course of performance, oral understanding or other
          circumstances.  Terms and conditions may be waived or amended only in
          writing executed by the Bank Group or, in appropriate circumstances,
          the Bank  Group Majority.

     D.   Communications.  Whenever any communication is required by the terms
          of the Loan Documents or by law, it will be deemed delivered when
          delivered personally or by facsimile machine or on the third Banking
          Day after it is mailed in a postage prepaid envelope addressed to the
          intended recipient at the address specified below or such other
          address as a party may hereafter specify by written notice to the
          other parties.

     E.   Costs.  The Contran Companies will pay on demand all reasonable direct
          costs and expenses, including reasonable attorney fees, incurred by
          the Agent in drafting, negotiating, modifying and reviewing the Loan
          Documents.

     F.   Counterparts.  The Loan Documents may be executed in any number of
          counterparts, each of which shall be deemed to be an original, and all
          of which, taken together shall constitute one and the same contract.
     G.   Statutory Statement.  Under Oregon Law, most agreements, promises and
          commitments made by a financial institution after October 3, 1989,
          concerning Advances and other credit extensions which are not for
          personal, family or household purposes or secured solely by the
          borrower's residence must be in writing, express consideration and be
          signed by the financial institution to be enforceable.

     Richard M. Lewis



                           LOAN AND PLEDGE AGREEMENT

     THIS LOAN AND PLEDGE AGREEMENT (hereinafter referred to as this
"Agreement"), executed on the 18th day of August, 1986, by and between DIXIE
RICE AGRICULTURAL CORPORATION, INC., a Louisiana corporation (hereinafter
referred to as the "Borrower"), and SOUTHERN METHODIST UNIVERSITY, a Texas non-
profit corporation (hereinafter referred to as "SMU").

                              W I T N E S S E T H:

     WHEREAS, Borrower has requested that SMU extend a revolving line of credit
in the amount of S1,500,000.00 to be secured by certain of Borrower's marketable
securities and SMU is willing to extend such line of credit on the terms and
conditions set forth herein;

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements contained herein, the parties hereto hereby agree as
follows:

     1.   COMMITMENT OF SMU.  Subject to the terms and conditions hereinafter
set forth, SMU agrees, at any time and from time to time during the period
beginning on the date of this Agreement and continuing through and including
June 30, 1996, to make one or more advances (hereinafter collectively referred
to as the "Advances") to Borrower under a revolving line of credit (the
"Commitment").  The aggregate amount of the Advances outstanding at any one time
shall not exceed the sum of $1,500,000.00. Each Advance under the Commitment
shall be subject to satisfactory compliance by Borrower with all provisions of
this Agreement including the procedure for requesting Advances set forth in
Section 7 hereof.  Within the limits of the Commitment, Borrower may borrow,
repay and reborrow without penalty or premium.  Notwithstanding any other
provision of this Agreement, no Advance shall be required to be made hereunder
if any Event of Default (as hereinafter defined) has occurred and is continuing,
or if any event or condition has occurred that may, with notice or the passage
of time, be an Event of Default.

     2.   NOTE EVIDENCING BORROWINGS. The Commitment shall be evidenced by a
promissory note of Borrower, in form and substance satisfactory to SMU, such
note bearing interest and being payable as set forth in Exhibit "A" attached
hereto and made a part hereof by reference for all purposes, with appropriate
insertions (hereinafter referred to as the "Note").

     3.   PLEDGE OF COLLATERAL.  In consideration of the Commitment and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged and confessed, Borrower hereby grants, assigns, transfers and sets
over to SMU a continuing security interest in and to the collateral described in
this Agreement (hereinafter referred to as the "Collateral"), and the
certificates representing the Collateral.  Collateral includes, without
limitation, (a) all money, instruments and property of Borrower this day
delivered to and deposited with SMU, and all money, instruments and property of
Borrower heretofore delivered or which shall hereafter be delivered to or come
into the possession, custody or control of SMU in any manner or for any purpose
whatever during the existence of this Agreement, (b) any additional Shares
(defined herein) which may be delivered to SMU after the date hereof pursuant to
the agreement contained herein, and (c) the proceeds of any and all such
property.

     4.   SECURED INDEBTEDNESS.  The security interest granted herein is given
to ratably secure the performance and payment of Borrower's obligations,
liabilities and indebtedness arising under or in connection with the Note and
this Agreement (hereinafter referred to as the "Secured Indebtedness").

     5. COLLATERAL.  The, word "Shares," as used herein, shall mean collectively
any and all shares of stock listed for trading and actively traded on the New
York Stock Exchange or American Stock Exchange or real-time reported NASDAQ
securities or such other securities as may be acceptable to SMU, which Borrower
has deposited with SMU contemporaneously with, or prior to, the execution of
this Agreement, and such additional shares of stock that Borrower may from time
to time in the future deposit with SMU pursuant to the terms of this Agreement.
SMU may, at its option, give written or telegraphic notice to any and all
parties issuing the Shares or having in their possession any Collateral for
which they or others are accountable to Borrower, to hold and dispose of such
Collateral for the account of SMU and to send such Collateral directly to SMU at
its address shown herein, and to thereafter treat and regard SMU as the assignee
and transferee of Borrower and entitled in its place and stead to receive any
and all Collateral.  Without in any way limiting the effectiveness of the
authorization and direction in the next preceding sentence, if Borrower shall
receive any such Collateral which is hereby receivable by SMU, Borrower shall
hold the same in trust and shall remit and deliver, or cause to be remitted and
delivered, such Collateral immediately and forthwith, to SMU.  SMU shall have no
responsibility whatsoever to obtain the deposit of such Collateral.  The
inclusion of proceeds in this Agreement does not authorize Borrower to sell,
transfer, dispose of or otherwise use the Collateral in any manner not
specifically authorized herein.

     Borrower covenants and agrees with SMU that so long as any Secured
Indebtedness is outstanding, it will deposit and maintain on deposit with SMU
Shares which at all times are valued at not less than two hundred percent (200%)
of the outstanding principal balance of the Note (the "Minimum Value"), as
determined by daily closing market price quotations (either last trade or
average of last bid and asked prices) from the New York Stock Exchange, American
Stock Exchange, NASDAQ or other regularly published source.  Any Shares not
traded on a particular day shall be valued as of such day at the average
(weighted by days elapsed) of the values of such Shares on the next preceding
and next following days on which such Shares are traded.  In the event on the
last day of any March, June, September or December (hereinafter referred to as a
"Determination Date"), commencing September 30, 1986, the value of the Shares
deposited with SMU as so determined falls below the Minimum Value, Borrower
covenants and agrees to deposit with SMU within ten (10) days following such
Determination Date additional Shares sufficient to increase the value of the
Shares to at least the Minimum Value.  In the event, on any Determination Date,
the value of the Shares deposited with SMU exceeds two hundred ten percent
(210%) of the outstanding principal balance of the Note (the "Maximum Value"),
SMU agrees to promptly deliver to Borrower sufficient Shares selected by SMU in
its sole discretion to reduce the value of the Shares to below the Maximum
Value.

     6.   REPRESENTATIONS AND WARRANTIES.  Borrower represents and warrants to
SMU that:

          (a)  Corporate Existence.  Borrower is a corporation duly organized,
     validly existing, and in good standing under the laws of the jurisdiction
     in which it is incorporated and is duly qualified as a foreign corporation
     in all jurisdictions wherein the property owned or to the best of its
     knowledge the business transacted by it makes such qualification necessary;

          (b)  Corporate Power and Authorization.  Borrower is duly authorized
     and empowered to execute and deliver this Agreement, and to create and
     issue the Note, and all corporate and other action on the part of Borrower
     for the due creation and issuance of the Note and for the due execution,
     delivery and performance of this Agreement has been duly and effectively
     taken;

          (c)  Binding Obligations.  This Agreement does, and the Note upon its
     creation, issuance, execution and delivery will, constitute valid and
     binding obligations of Borrower, enforceable in accordance with their terms
     (except that enforcement may be subject to any applicable bankruptcy,
     insolvency or similar laws generally affecting the enforcement of
     creditors' rights and subject to availability of equitable remedies);

          (d)  No Legal Bar or Resultant Lien.  This Agreement and the Note do
     not and will not violate any provisions of any contract, agreement, law,
     regulation, order, injunction, judgment, decree or writ to which Borrower
     is subject, or result in the creation or imposition of any lien or other
     encumbrance upon any assets or properties of Borrower, other than those
     contemplated by this Agreement;

          (e)  No Consent.  Borrower's delivery and performance of this
     Agreement and the Note do not require the consent or approval of any other
     person or entity, including without limitation any regulatory authority or
     governmental body of the United States or any state thereof or any
     political subdivision of the United States or any state thereof;

          (f)  Investments and Guaranties.  Borrower has made no investments in,
     advances to or guaranties of the obligations of any person or entity,
     except as reflected in its most recent Financial Statements (defined
     herein) delivered to SMU.  As used herein, the term "Financial Statements"
     shall mean balance sheets, income statements and appropriate footnotes and
     schedules, prepared in accordance with generally accepted accounting
     principles and consistent with prior periods.

          (g)  Liabilities.  Except for liabilities incurred in the normal
     course of business, Borrower has no material (individually or in the
     aggregate) liabilities, direct or contingent, except as disclosed or
     referred to in the Financial Statements.  Except as described in the
     Financial Statements, there is no litigation, legal or administrative
     proceeding, investigation or other action of any nature pending or, to the
     knowledge of Borrower, threatened against or affecting Borrower which
     involves the possibility of any judgment or liability not fully covered by
     insurance, and which might be reasonably expected to have a Material
     Adverse Effect (defined herein).  As used herein, the term "Material
     Adverse Effect" shall mean any material and adverse effect on (i) the
     assets or properties, liabilities, financial condition, business,
     operations, affairs or circumstances of Borrower from those reflected in
     the Financial Statements or from the facts represented or warranted in this
     Agreement, or (ii) the ability of Borrower to carry out its business as at
     the date of this Agreement or as proposed at the date of this Agreement to
     be conducted or to meet its obligations under the Note or this Agreement on
     a timely basis.  No unusual or unduly burdensome restrictions, restraint,
     or hazard exists by contract, law or governmental regulation or otherwise
     relative to the business, assets or properties of Borrower, except as known
     to affect its industry generally, which might reasonably be expected to
     have a Material Adverse Effect;

          (h)  Taxes: Governmental Charges.  Borrower has filed all tax returns
     and reports required to be filed and has paid taxes, assessments, fees and
     other governmental charges levied upon it or upon any of its assets,
     properties or income which are due and payable, including interest and
     penalties, or has provided adequate reserves, if required, in accordance
     with generally accepted accounting principles for the payment thereof,
     except such as are being contested in good faith by appropriate proceedings
     and for which adequate reserves for the payment thereof as required by
     generally accepted accounting principles have been provided;

          (i)  Titles, etc.  Borrower has good and marketable legal and
     beneficial title to the Collateral and to its assets and properties, free
     and clear of all liens or other encumbrances except those referred to in
     the Financial Statements, and those heretofore disclosed to SMU in writing,
     and has the right to transfer any and all interests therein;

          (j)  Defaults.  Borrower is not in default and no event or
     circumstance has occurred which, but for the passage of time or the giving
     of notice, or both, would constitute a default under any loan or credit
     agreement, indenture, mortgage, deed of trust, security agreement or other
     agreement or instrument in any respect that might be reasonably expected to
     have a Material Adverse Effect.  No Event of Default hereunder has occurred
     and is continuing;
          (k)   Casualties; Taking of Properties.  Since the dates of the
     Financial Statements neither the business nor the assets or properties of
     Borrower has been materially and adversely affected as a result of any
     fire, explosion, earthquake, flood, drought, windstorm, accident, strike or
     other labor disturbance, embargo, requisition or taking of property or
     cancellation of contracts, permits or concessions by any domestic or
     foreign government or any agency thereof, riot, activities of armed forces
     or acts of God or of any public enemy;

          (1)  Use of Proceeds; Margin Stock.  The proceeds of the Note will be
     used by Borrower solely (i) to provide funds for working capital, (ii) to
     provide funds for repayment of existing loans, or (iii) other general
     corporate purposes.  Borrower will not use any part of the proceeds of the
     Note for the purpose of "purchasing" or "carrying" any "margin stock" as
     such terms are defined in Regulations U, G, T or X of the Board of
     Governors of the Federal Reserve System, or for the purpose of reducing or
     retiring any indebtedness which was originally incurred to purchase or
     carry a margin stock or for any other purpose which might constitute this
     transaction a "purpose credit" within the, meaning of said Regulation U.
     Borrower is not engaged in the business of extending credit for the purpose
     of purchasing or carrying margin stock.  Neither Borrower nor any person or
     entity acting on behalf of Borrower has taken or will take any action which
     might cause the loans hereunder to violate Regulation U or any other
     regulation of the Board of Governors of the Federal Reserve System or to
     violate the Securities Exchange Act of 1934 or any rule or regulation
     thereunder, in each case as now in effect or as the same may hereafter be
     in effect;

          (m)  Compliance with the Law.  Borrower:

               (i)  is not in violation of any law, judgment, decree, order,
          ordinance, or governmental rule or regulation to which Borrower or any
          of its assets or properties is subject; or

               (ii) has not failed to obtain any license, permit, franchise or
          ether governmental authorization necessary to the ownership of any of
          its assets or properties or the conduct of its business;

     which violation or failure might reasonably be expected to have a Material
     Adverse Effect;

          (n)  No Material Misstatements.  No information, exhibit or report
     furnished by Borrower to SMU in connection with the negotiation of this
     Agreement contains any material misstatement of fact or omits to state a
     material fact or any fact necessary to make the statement contained therein
     not misleading;

          accept such Collateral as security for the Commitment;

               (iii)     In the event SMU determines that the proposed

     or if an Event of Default has occurred, specifying the Event of Default and
     the nature and status thereof; (ii) to the extent requested from time to
     time by SMU, specifically affirming compliance of Borrower in all material
     respects with any of the representations or obligations under said
     instruments; and (iii) containing or accompanied by such financial or other
     details, information and material as SMU may reasonably request to evidence
     such compliance;

          (b)  Taxes and Other Liens.  Borrower will pay and discharge promptly
     all taxes, assessments and governmental charges or levies imposed upon
     Borrower or upon the income or any assets or property of Borrower as well
     as all claims of any kind (including claims for labor, materials, supplies
     and rent) which, if unpaid, might become a lien or other encumbrance upon
     any or all of the assets or property of Borrower, provided, however, that
     Borrower shall not be required to pay any such tax, assessment, charge,
     levy or claim if the amount, applicability or validity thereof shall
     currently be contested in good faith by appropriate proceedings diligently
     conducted and if Borrower shall have set up reserves therefor adequate, if
     required, under generally accepted accounting principles;

          (c)  Further Assurances.  Borrower will cure promptly any defects in
     the creation and issuance of the Note and the execution and delivery of

     instruments in compliance with or accomplishment of the covenants and
     agreements in this Agreement, or to correct any omissions in the Note or
     more fully to state the obligations set out herein;

          (d)  Performance of Obligations.  Borrower will pay the Note and other
     obligations incurred by it hereunder according to the reading, tenor and

     Borrower hereunder, at the time or times and in the manner specified;

          (e)  Reimbursement of Expenses.  Borrower will, upon request, promptly
     reimburse SMU for all amounts expended, advanced or incurred by SMU to
     satisfy any obligation of Borrower under this Agreement, or to protect the
     assets or business of Borrower or to collect the loans made hereunder, or
     to enforce the rights of SMU under this Agreement, which amounts will
     include all court costs, attorneys' fees, fees of auditors and accountants,
     and investigation expenses reasonably incurred by SMU in connection with
     any such matters, together with interest at either (i) the highest lawful
     rate permitted by law an each such amount from the date that the same is
     expended, advanced or Incurred by SMU until the date of reimbursement to
     SMU, or (ii) if no Event of Default shall have occurred and be continuing,
     the pre-maturity rate specified in the Note on each such amount from the

     demand or request by SMU for the reimbursement of same, and thereafter at
     the rate specified in clause (i) above until the date of reimbursement to
     SMU.  In the event SMU elects to pay such amounts and Borrower falls to
     reimburse SMU therefor as provided in this Subsection, SMU may make
     advances at its own initiation for the account of Borrower on the Note to
     provide for such reimbursement, without the necessity of a request for
     advance from Borrower, and such advances shall be a part of the
     indebtedness of Borrower under this Agreement;

          (f)  Accounts and Records.  Borrower will keep books of record and

     often as SMU may request; and

          (h)  Notice of Certain Events.  Borrower shall promptly notify SMU if
     Borrower learns of the occurrence of (i) any event which constitutes an
     Event of Default, together with a detailed statement by Borrower of the
     steps being taken to cure the Event of Default; or (ii) the receipt of any
     notice from, or the taking of any other action by the holder of any
     promissory note, or other evidence of indebtedness of Borrower with respect
     to a claimed default, together with a detailed statement by Borrower
     specifying the notice given or other action taken by such holder and the
     nature of the claimed default and what action Borrower is taking or
     proposes to take with respect thereto; or (iii) any legal, judicial or
     regulatory proceedings affecting Borrower or any of the assets or
     properties of Borrower in which the amount involved is material and is not
     covered by insurance or which, if adversely determined, could reasonably be
     expected to have a Material Adverse Effect; or (iv) any dispute between
     Borrower and any governmental or regulatory body or any other person or
     entity which, if adversely determined, might reasonably be expected to
     cause a Material Adverse Effect, except as known to affect the oil and gas
     industry generally.

     assets or properties (whether now owned or hereafter acquired) to, any
     person or entity (i) unless the stockholders' equity of the successor
     entity (whether or not Borrower) is equal to or greater than the
     stockholders' equity of Borrower immediately before such transaction and

               (iii)     Default shall be made in the due observance or

     notice and without presentment, demand, protest, notice of protest or

     may declare the principal of, and all interest then accrued on, the Note
     and any other liabilities hereunder to be forthwith due and payable,
     whereupon the same shall forthwith become due and payable without

     Borrower hereby expressly waives, anything contained herein or in the Note
     to the contrary notwithstanding.  Nothing contained herein shall be
     construed to limit or amend in any way the Events of Default enumerated in
     the Note, or any other documents executed in connection with the

          (c)  Upon the occurrence of an Event of Default, and at anytime

     its sole discretion, sell, transfer, assign and deliver all or any part of
     the Collateral at public or private sale, and thereafter, SMU may bring
     suit for any deficiency remaining after any public or private sale of the
     Collateral.

          (d)  This Agreement, SMU's rights hereunder and/or the Secured
     Indebtedness, or any part thereof, may be assigned from time to time by
     SMU.  SMU may at any time following the occurrence of an Event of Default
     hereunder (i) transfer the Collateral to SMU or its nominee, pursuant to
     the applicable provisions of the Texas Uniform Commercial Code, and/or (ii)

     any right or remedy under this Agreement without waiving that or any other
     right or remedy of hereunder.

     11.  EXERCISE OF RIGHTS.  No failure to exercise, and no delay in
exercising, on the part of SMU, any right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right.  The rights of SMU
hereunder shall be in addition to all other rights provided by law.  No
modification or waiver hereof or of any provision of the Note, nor consent to
departure therefrom, shall be effective unless in writing, and no such consent
or waiver shall extend beyond the particular case and purpose involved.  No
notice or demand given in any case shall constitute a waiver of the right to
take other action in the same, similar or other instances without such notice or
demand.

     12.  NOTICES.  If notice to Borrower of the public sale or private sale or
other disposition of the Collateral is required by the Texas Uniform Commercial
Code, such notice shall be sufficient If SMU gives written notice to Borrower
five (5) days prior to the date of any public sale of the Collateral or five
(5). days prior to the date after which any private sale or other disposition of
the Collateral win be made.  Any notices or other communications required or
permitted to be given by this Agreement or any other documents and instruments
referred to herein must be given in writing and must be personally delivered or
mailed by prepaid certified or registered mail to the party to whom such notice
or communication is directed at the address of such party as follows: (a)
BORROWER: 4835 LBJ Freeway, Suite 600, Dallas, Texas 75244, Attention: Chief
Executive Officer; or (b) SMU: P.O. Box 193, SMU Station, Southern Methodist
University, Dallas, Texas 75275, Attention: Vice President for Finance and
Administration.  Any such notice or other communication shall be deemed to have
been given (whether actually received or not) on the day it is personally
delivered as aforesaid or, if mailed, on the day after it is mailed as
aforesaid.  Any party may change its address for purposes of this Agreement by
giving notice of such change to all other parties pursuant to this Section.

     13.  GOVERNING LAW.  This Agreement is being executed and delivered, and is
intended to be performed, in Dallas, Texas, and the substantive laws of such
state shall govern the validity, construction, enforcement and interpretation of
this Agreement and all other documents and instruments referred to herein,
unless otherwise specified therein or unless the laws of another state require
the application of the laws of such state.

     14.  INVALID PROVISIONS.  If any provision of this Agreement is held to be
illegal, invalid or unenforceable under present or future laws effective during
the term of this Agreement, such provisions shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a part of this Agreement, and the
remaining provisions of this Agreement shall remain in full force and effect and
shall not be affected by the illegal, invalid or unenforceable provision or by
its severance from this Agreement.

     15.  MAXIMUM INTEREST RATE.

          (a)  Regardless of any provisions contained in this Agreement or in
     any other documents and instruments referred to herein or any other
     instrument or agreement entered into in connection with or as security for
     the Note, SMU shall never be deemed to have contracted for or be entitled
     to receive, collect or apply as interest on the principal amount evidenced
     by the Note, any amount in excess of an amount which would result in
     exceeding the maximum rate of interest permitted to be charged by
     applicable law.  In the event the maturity of the Note is accelerated by
     reason of an election of the holders thereof resulting from any Event of
     Default under this Agreement, or otherwise, or in the event of any required
     or permitted prepayment, then such consideration that constitutes interest
     under applicable law may never include more than the maximum amount allowed
     by such applicable law, and excess interest, if any, provided for in this
     Agreement, the Note or otherwise shall be cancelled automatically as of the
     date of such acceleration and if theretofore paid shall be applied to the
     reduction of the unpaid principal balance of the Note and if the principal
     balance of the Note is paid in full, any remaining excess shall forthwith
     be paid to Borrower.  In determining whether or not the amount of interest
     paid or payable under any specific contingency exceeds an amount which
     would result in exceeding the maximum rate of interest permitted under
     applicable law, SMU and Borrower shall, to the extent permitted under
     applicable law (i) characterize any non-principal payment as an expense,
     fee or premium rather thin as interest; and (ii) exclude voluntary
     prepayments and the effect thereof; and (iii) compare the total amount of
     interest contracted for, charged or received throughout the entire
     contemplated term of the Note at the maximum lawful rate under applicable
     law.

          (b)  If at any time and from time to time SMU is prevented from
     collecting the rate of interest and the fees specified in the Note, by
     applicable law or governmental regulation, it shall be entitled to recoup
     the amount it would have otherwise been able to collect when such
     recoupment will not violate such applicable law or governmental regulation.
     Such recoupment shall be accomplished by Borrower paying interest at the
     highest lawful rate until such time as SMU shall have fully recouped the
     interest it would have otherwise been able to collect from Borrower in the
     absence of such applicable law or governmental regulation.  During any such
     period of recoupment, interest collected by SMU shall first be credited to
     payment of current interest due at the rate specified in the Note, then any
     remaining interest collected shall. be applied to recoupment.  When SMU
     shall have recouped all such interest, the interest rate payable by
     Borrower shall revert to the rate specified in the Note.  In no event,
     however, shall the interest rate charged hereunder ever exceed the maximum
     rate of interest permitted by law.

     16.  ENTIRETY AND AMENDMENTS.  This Agreement, the Note, and/or any other
documents and instruments referred to herein, embody the entire agreement
between the parties and supersede all prior agreements and understandings, if
any, relating to the subject matter hereof and thereof, and any provision hereof
or of the  Note, may be amended or waived only by an instrument in writing
executed by Borrower and SMU.

     17.  MULTIPLE COUNTERPARTS: APPROVAL.  This Agreement may be executed in a
number of identical separate counterparts, each of which for all purposes is to
be deemed an original, but. all of which shall constitute, collectively, one
agreement.  No party to this Agreement shall be bound hereby until (a) a
counterpart of this Agreement has been executed and delivered by all parties
hereto, and (b) the terms and provisions of this Agreement, and the execution
and delivery thereof by SMU, shall have been duly approved by the Investment
Committee of the Board of Governors of SMU.

     18.  SURVIVAL.  All covenants, agreements, undertakings, representations
and warranties made herein, in the Notes or other documents and instruments
referred to herein, shall survive all closings hereunder and shall not be
affected by any investigation made by any party.

     19.  PARTIES BOUND.  This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns, heirs,
legal representatives and estates; provided, however, that Borrower may not,
without the prior written consent of SMU, assign any rights, powers, duties or
obligations hereunder.

                                PROMISSORY NOTE

$1,500,000.00             Dallas, Texas            August 18, 1986

     FOR VALUE RECEIVED, the undersigned, DIXIE RICE AGRICULTURAL CORPORATION,
INC., a Louisiana corporation (the "Maker"), hereby unconditionally promises to
pay to the order of SOUTHERN METHODIST UNIVERSITY, a Texas nonprofit corporation
("SMU"), at its offices in University Park, Dallas County, Texas, the principal
sum of ONE MILLION FIVE HUNDRED THOUSAND and NO/100 DOLLARS ($1,500,000.00) or,
if less, the aggregate unpaid balance of all amounts advanced to Borrower
pursuant to that certain Loan and Pledge Agreement of even date herewith by and
between Maker and SMU (the "Loan Agreement"), in lawful money of the United
States of America, together with interest at the lesser of (a) the Maximum Rate
(defined herein) or (b) as follows (the "Contract Rate"):

          (i)  from the date of this Note and continuing until June 30, 1988,
     this Note shall bear interest at the rate of seven and one-half percent (7-
     1/2%) per annum;

          (ii) From and after June 30, 1988 and continuing until maturity, this
     Note shall bear interest at a rate to be determined annually on each June
     30 (the "Interest Determination Date"), beginning June 30, 1988.  The rate
     of interest for the twelve (12) month period immediately following each
     Interest Determination Date shall be equal to the greater of (a) seven and
     one-half percent (7-1/2%) per annum, or (b) seventy-six percent (.76)
     multiplied times the Index (defined herein) for the month including such
     Interest Determination Date.  As used herein, the term "Index" shall mean
     the Shearson Lehman Brothers Inc. Bond Market Report - Corporate Bond Index
     - Long Term (Average) Yield (which Index for June 1986 was 9.90 %) or if
     same is no longer published, the successor index, if any, or if none is
     available, a substantially equivalent index for obligations of the same
     maturity and quality as designated by SMU with the consent of Maker, which
     consent shall not be unreasonably withheld.

     The term "Maximum Rate" as used herein includes, as to Article 5069-1.04,
Vernon's Texas Civil Statutes (and as the same may be incorporated by reference
in other Texas statutes), but otherwise without limitation, the rate based upon
the "indicated rate ceiling." All past due principal and interest of this Note
shall bear interest at the highest lawful rate until paid.

     Interest on this Note is due and payable quarterly as it accrues, on the
last day of each September, December, March and June, commencing September 30,
1986.  The principal balance of this Note outstanding on June 30, 1996 (the
"Conversion Date"), together with all accrued but unpaid interest, is due and
payable in thirty-nine (39) consecutive quarterly installments, each in the
amount of 1/40th of the principal balance of this Note outstanding on the
Conversion Date, commencing September 30, 1996 and continuing on the last day of
each December, March, June and September thereafter, with one (1) final
installment being due and payable. on June 30, 2006 in an amount equal to the
outstanding principal balance of this Note, plus all accrued but unpaid
interest.  All installments of principal and interest are payable at SMU's
office in University Park, Dallas County, Texas.

     This Note is executed and delivered pursuant to the Loan Agreement and is
the Note referred to therein, and is secured by capital stock in certain
publicly traded corporations.  Reference is made to the Loan Agreement for a
description of the properties pledged and assigned, the nature and extent of the
security and the rights of the parties under the Loan Agreement in respect of
such security.  Upon the occurrence of any Event of Default (as such term is
defined in the Loan Agreement), the principal balance hereof and the interest
accrued hereon may be declared to be forthwith due and payable, whereupon the
holder will have the remedies provided in the Loan Agreement.

     Regardless of any provision contained in this Note, no holder of this Note
shall ever be entitled to receive, collect or apply, as interest on any amount
owing, hereunder, any amount in excess of the highest lawful rate of interest
permitted to be charged by applicable law, and in the event any holder of this
Note ever receives, collects or applies, as interest, any such excess, such
amount which would be excessive interest shall be deemed a partial prepayment of
principal and treated hereunder as such; and if the principal amount of this
Note is paid in full, any remaining excess shall forthwith be paid to the Maker.
In determining whether or not the interest paid or payable, under any specific
contingency, exceeds the highest lawful rate permitted by law, the undersigned
and any holder of this Note shall, to the maximum extent permitted under
applicable law, (i) characterize any non-principal payment as an expense, fee or
premium rather than as interest, (ii) exclude voluntary prepayments and the
effect thereof, and (iii) compare the total amount of interest contracted for,
charged or received with the total amount of interest which could be contracted
for, charged or received throughout the entire contemplated term of this Note at
the maximum lawful rate under applicable law; provided that if this Note is paid
and performed in full prior to the end of the full contemplated term thereof,
and if the interest received for the actual period of existence hereof exceeds
the highest lawful rate permitted by law, the holder of this Note shall refund
to the undersigned the amount of such excess or credit the amount of such excess
against the principal amount of this Note, and in such event, no holder of this
Note shall be subject to any penalties provided by any laws for contracting for,
charging or receiving interest in excess of the highest lawful rate permitted by
law.

     If at any time and from time to time SMU is prevented from collecting the
Contract Rate and the fees specified in this Note, by applicable law or
governmental regulation, it shall be entitled to recoup the amount it would have
otherwise been able to collect when such recoupment will not violate such
applicable law or governmental regulation.  Such recoupment shall be
accomplished by the Maker paying interest at the highest lawful rate until such
time as SMU shall have fully recouped the interest it would have otherwise been
able to collect from Maker in the absence of such applicable law or governmental
regulation.  During any such period of recoupment, interest collected by SMU
shall first be credited to payment of current interest due at the Contract Rate,
then any remaining interest collected shall be applied to recoupment.  When SMU
shall have recouped all such interest, the interest rate payable by Maker shall
revert to the Contract Rate.  In no event, however, shall the interest rate
charged hereunder ever exceed the maximum rate of interest permitted by law.

     If this Note is placed in the hands of an attorney for collection, or if it
is collected through any legal proceeding at law or in equity or in bankruptcy,
receivership or other court proceedings, Maker agrees to pay all costs of
collection, including but not limited to court costs and reasonable attorneys'
fees.

     Maker and each surety, endorser, guarantor and other party ever liable for
payment of any sums of money payable on this Note, jointly and severally waive
presentment and demand for payment, notice of intention to accelerate the
maturity, acceleration, protest, notice of protest and nonpayment, as to this
Note and as to each and all installments hereof, and agree that their liability
under this Note shall not be affected by any renewal or extension in the time of
payment hereof, or in any indulgences, or by any release or change in any
security for the payment of this Note.
