SMITH CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS June 30, 1994 (unaudited) 1. Basis of Presentation --------------------- The financial statements presented herein are based on interim figures and are subject to audit. In the opinion of management, all adjustments consisting of normal accruals considered necessary for fair presentation of the results of operations and of financial position have been made. The results of operations for the six-month period ended June 30, 1994 are not necessarily indicative of the results expected for the full year. The consolidated balance sheet as of December 31, 1993 is derived from the audited financial statements but does not include all disclosures required by generally accepted accounting principles. 2.

Long-Term Debt -------------- On April 5, 1994, the $12.5 million 8.9 percent term loan agreement was amended to carry a floating interest rate as of April 1994 and the final maturity was extended from April 1996 to April 1999. The interest rate is set at 50 basis points over LIBOR and the loan can be repaid at any time without penalty. On June 15, 1994, the Corporation put in place a $140 million revolving credit agreement which replaced a $115 million A. O. Smith facility and a $30 million AgriStor Credit Corporation facility. The term of the amended agreement was extended two years until April 3, 1998. In addition to lower fees and lower borrowing rates the agreement contains fewer restrictive covenants. Due to a continuing reduction in funding needs, AgriStor Credit Corporation terminated its commercial paper program on June 15, 1994. The Corporation's long-term credit agreements contain certain conditions and provisions which restrict the Corporation's payment of dividends. Under the most restrictive of these provisions, retained earnings of $91.9 million were unrestricted as of June 30, 1994 for cash dividends and treasury stock purchases. PART 1--FINANCIAL INFORMATION ITEM 2--MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Results of Operatons - First six months of 1994 compared to 1993 The combination of effective business strategies and favorable economic conditions were reflected in the Corporation's results for the first six months and second quarter of 1994 as sales and earnings for these periods surpassed those of any previous comparable period. Through the first half of the year, all product operations of the Corporation except Fiberglass Products, exceeded their sales and earnings of the corresponding period last year. Revenues for the first half of 1994 were $690 million or almost 13 percent better than the $611.9 million of revenues in the same period of 1993. Revenues of $350.2 million in the second quarter of 1994 surpassed last year's second quarter by $34.4 million or almost 11 percent. The Corporation earned $33.7 million for the first half of 1994 compared to $28.1 million in the first half of 1993. Second quarter earnings were $18.0 million in 1994, an increase of $2.9 million or 19 percent over the $15.1 million earned in the same quarter of 1993. The second quarter gross margin of 16.7 percent compared favorably to the 16.4 percent margin in the same period of 1993. Increased volume and improved manufacturing efficiencies at the Electrical Products Company were the major reasons for the second quarter improvement in profit margin and offset higher new product launch costs at Automotive. The gross profit margin through the first half of the year was 16.2 percent or slightly lower than the 16.3 percent realized in the same period in 1993 reflecting conditions in the first quarter including new product launch costs at Automotive and competitive conditions in the electric motors markets. The domestic automotive industry demonstrated a continuation of the market expansion that has occurred over the past year and a half, with particularly high demand for light truck products in which the Automotive Products Company has a concentration of its revenues. Automotive increased sales by approximately 17 percent in both the first half and second quarter of 1994 when compared to the same periods of 1993. Automotive's earnings during 1994 have been sufficient to absorb the costs associated with a number of new product launches during the year and reflected double digit percentage increases over the comparable periods of 1993. Assuming the continued popularity of the vehicles for which the Company is a supplier, the outlook for the remainder of the year is encouraging. Equity in earnings of the Corporation's 40 percent owned Mexican affiliate were lower in the second quarter and first half of 1994 compared to 1993 as the result of start up costs for new product along with costs incurred to realign manufacturing operations. These costs are expected to diminish through the rest of 1994 and second half results should show some improvement. Year-to-date sales in 1994 for the Water Products company were $130.8 million or 6.7 percent higher than the first half of 1993. The majority of the increase in sales from year-to-year occurred in the residential heater business. Sales for the second quarter of 1994 were comparable to 1993 second quarter sales and reflected both increased residential sales and an industry wide downturn in the commercial heater business due to a build-up of distributor inventories which occurred late in 1993 and early 1994. Operating profits for Water Products in the first half of 1994 were improved over the same period of 1993. The impact of increased residential heater volume more than offset the adverse effect of a reduction in the volume of the higher margin commercial product. Profits for the second quarter of 1994 were at the same level as the second quarter of 1993. Improved demand for commercial product is expected in the third quarter as distributors begin to replenish their inventory. Given year-to-date results, strengthening demand for commercial product and the introduction of a number of new residential and commercial products during the second half of the year, 1994 should show another solid earnings performance by Water Products. Management has been encouraged by the recent performance of the Electrical Products Company. Favorable conditions in the pump, air compressor, HVAC, and replacement segments of the business have manifested themselves in the form of increased sales in both the second quarter and first half of 1994 when compared to the same periods of 1993. 1994 first half sales were more than $15 million or 11.7 percent higher than the same period in 1993. The pace of incoming orders suggests that the outlook for third quarter volume is also good. The increased volume along with improved factory performance had a positive influence on Electrical Products earnings in the first six months of 1994 with an even more pronounced improvement in the second quarter compared to 1993. Sales for Smith Fiberglass Products were lower in 1994 than in 1993 for both the first half and second quarter as the prior year benefited from two large oil field shipments. Earnings were also lower than the same periods of 1993 as a result of reduced volume and the favorable impact last year of a non-recurring patent infringement lawsuit. The losses incurred by the agricultural operations in the second quarter and first half of 1994 were less than those incurred in the same period of 1993. The reasons for the reduced losses were twofold. Earnings for A. O. Smith Harvestore Products, Inc. were higher than those of the previous years due to strong activity in the municipal and industrial and water and waste storage markets and provisions in 1994 for product liability and bad debts were lower. Selling, general and administrative expenses in 1994 were higher than the respective periods of 1993 but declined as a percentage of sales. The $3.0 million increase from the first half of 1993 to the first half of 1994 was due to higher employee incentive and profit sharing accruals associated with increased earnings and higher commissions and other expenses in support of increased sales volumes. Through the first six months of 1994, interest expense was 13 percent lower than in the same period of 1993 reflecting an approximate $20 million decline in debt since June 30, 1993, and refinancing of relatively higher cost borrowings. Non-operating expenses for 1994 reflect an unfavorable swing of approximately $1.5 million for both the second quarter and first half when compared to the same periods of 1993. A judgment in a patent infringement suit and the settlement of a malpractice suit resulted in approximately $4.7 million of non-operating income in the second quarter of 1993 offset in part by a $2.8 million write-off related to impaired assets. The effective tax rate declined from approximately 40% in 1993 to around 38% in 1994. The favorable impact of research and development and foreign tax credits recognized in 1994 more than offset the rate increase associated with the Revenue Reconciliation Act of 1993. The Corporation remains optimistic that the markets it serves will continue to expand throughout 1994 and into 1995, and that 1994 financial results should surpass last year's record setting results. Liquidity and Capital Resources -------------------------------- The Corporation's working capital was $115.3 million at June 30, 1994 compared to $80.7 million at December 31, 1993. Increased sales and seasonally related increases in trade receivables, inventories and other current assets were partially offset by related increases in trade payables and other accrued liabilities. Cash flow provided by operations was $27.8 million less than the same period last year as the improved earnings were more than offset by higher working capital requirements. While the Corporation's long-term debt increased slightly in the first six months to $150.6 million due to the increased working capital requirements, the debt to equity ratio of 49.8% was improved over the same time last year when it was 55.2%. The long- term debt of the finance subsidiary declined $6.4 million to $35.4 million reflecting the continuing liquidation of that business. The Corporation anticipates that a combination of current earnings trends and moderating seasonal working capital requirements will reduce debt and further improve its debt-to-equity ratio during the balance of 1994. Capital spending continues at higher levels due largely to new automotive product programs and could exceed $70 million in 1994. In April, the $12.5 million 8.9 percent term loan agreement was amended to carry a floating interest rate and the final maturity was extended from April 1996 to April 1999. In addition, in June, the Corporation put in place a $140 million revolving credit agreement which replaced a $115 million A. O. Smith facility and a $30 million AgriStor Credit Corporation facility. The term of the agreement was extended two years to April 3, 1998. In addition to lower fees and lower borrowing rates, the agreement contains fewer restrictive covenants (see Note 3). At its June 7, 1994 meeting, A. O. Smith's Board of Directors declared a regular quarterly dividend of $.13 per share on its common stock (Classes A and Common). The dividend is payable on August 15, 1994 to shareholders of record as of July 29, 1994. PART II -- OTHER INFORMATION ITEM 1 -- LEGAL PROCEEDINGS At June 30, 1994, the Corporation or A. O. Smith Harvestore Products, Inc. ("AOSHPI"), a wholly-owned subsidiary of the Corporation, were defendants in approximately twenty-seven (27) cases and two putative class action lawsuits filed by various plaintiffs who were alleging damages for economic losses claimed to have arisen out of alleged defects in AOSHPI's animal feed storage equipment. In the second quarter of 1994, three new cases were filed against the Corporation and AOSHPI and two cases were favorably resolved. The United States District Court for the Southern District of Ohio has set an October 16, 1995 trial date and approved the form of Notice which was mailed during the quarter to the class members in the conditionally certified class action brought on behalf of purchasers and lessees of Harvestore structures manufactured by the Corporation and AOSHPI. Information on these lawsuits was previously reported in Part I, Item 3 of the Corporation's 1992 and 1993 annual reports on Form 10-K and in Part II, Item 1 of the Corporation's Form 10-Q report for the quarterly period ended March 31, 1994 which are incorporated herein by reference. There have been no material changes in the environmental matters previously reported in Part I, Item 3 in the Corporation's 1993 annual report on Form 10-K which is incorporated herein by reference. ITEM 2 -- CHANGES IN SECURITIES Previously reported in Item 2, Part II of the Corporation's quarterly report on Form 10-Q for the quarter ended March 31, 1994, which is incorporated herein by reference. ITEM 4 -- SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS On March 3, 1994 the Corporation mailed a proxy statement to its stockholders relating to the annual meeting of stockholders on April 13, 1994. The annual meeting included the election of directors and the consideration and action upon proposals to increase the number of shares of Common Stock reserved under and make certain other amendments to and restate the 1990 Long Term Executive Incentive Compensation Plan, to approve the ratification of Ernst & Young as the independent auditors of the Corporation and to act upon two stockholder proposals, one relating to the cumulative voting in the election of directors and the other relating to the Maquiladora Operations. Directors are elected by the holders of each class of stock, voting as separate classes, with the holders of Class A Common Stock entitled to elect six directors and the holders of Common Stock entitled to elect three directors. In the other matters voted upon at the meeting, both classes of stock vote together as a single class, with the Class A Common Stock holders having one vote per share and the Common Stock holders having 1/10th vote per share. The voting results from the matters voted upon at the annual meeting were as follows: 1. Election of Directors Votes Broker Votes For Withheld Non-Votes Class A Common Stock Directors Tom H.

             8.  Borrowing by AgriStor Credit.  (a)  Each Bank severally
   agrees, on the terms and conditions set forth in the Credit Agreement as
   amended by this First Amendment, to make loans to AgriStor Credit
   ("AgriStor Loans") from time to time prior to August 1, 1994 in amounts
   not to exceed in the aggregate at any one time outstanding the amount of
   such Bank's Commitment less any Loans to the Borrower outstanding;
   provided that the aggregate principal amount of all AgriStor Loans at any
   one time outstanding shall not exceed $30,000,000.  At any time that
   AgriStor Loans are outstanding, the aggregate principal amount of Loans
   made to the Borrower and AgriStor Loans made to AgriStor by any Bank shall
   not exceed such Bank's Commitment.

             (b)  The AgriStor Loans shall be evidenced by notes (the
   "AgriStor Notes") substantially similar to the Domestic Notes and the
   Euro-Dollar Notes and shall be governed in all respects by those
   provisions in the Credit Agreement governing Loans made to the Borrower,
   including without limitation those provisions relating to principal
   amounts, interest, procedures for borrowing, payments and conditions for
   borrowing, with the sole exception that the primary obligor of the
   AgriStor Loans shall be AgriStor Credit rather than the Borrower.  Any
   Default or Event of Default under the Credit Agreement shall likewise be
   deemed to be a Default or Event of Default, as the case may be, with
   respect to the AgriStor Loans and the AgriStor Notes, and shall give rise
   to the same remedies and other rights with respect thereto as shall obtain
   under the Credit Agreement with respect to the Loans.

             9.  Representations and Warranties of Borrower.  The Borrower
   hereby represents and warrants that each of the representations and
   warranties of the Borrower contained in the Credit Agreement, as amended
   by this First Amendment, is true and correct on the date hereof as if made
   on and as of the date hereof except that representations and warranties
   that apply to a specific date were true and correct as of such date (with
   all references to "this Agreement" contained in the Credit Agreement being
   deemed to refer to the Credit Agreement as amended by this First Amendment
   and to this First Amendment).  After giving effect to this First Amendment
   and the transactions contemplated hereby, no Default or Event of Default
   has occurred and is continuing.

             10.  Representations and Warranties of AgriStor Credit. 
   AgriStor Credit hereby represents and warrants that:

             (a)  AgriStor Credit is a corporation duly incorporated, validly
        existing and in good standing under the laws of Delaware, and has all
        corporate powers and all material governmental licenses,
        authorizations, consents and approvals required to carry on its
        business as now conducted.

             (b)  The execution, delivery and performance by AgriStor Credit
        of this First Amendment and the AgriStor Notes are within AgriStor
        Credit's corporate powers, have been duly authorized by all necessary
        corporate action, require no action by or in respect of, or filing
        with, any governmental body, agency or official and do not
        contravene, or constitute a default under, any provision of
        applicable law or regulation or of the certificate of incorporation
        or by-laws of AgriStor Credit or of any agreement, judgment,
        injunction, order, decree or other instrument binding upon AgriStor
        Credit or result in the creation or imposition of any Lien on any
        asset of AgriStor Credit or any of its Subsidiaries.

             (c)  This First Amendment constitutes, and each AgriStor Note,
        when executed and delivered in accordance with this First Amendment,
        will constitute, the valid and binding obligation of AgriStor Credit
        enforceable in accordance with its terms, except as enforceability
        may be limited by applicable bankruptcy, insolvency, reorganization,
        moratorium or similar laws affecting the enforcement of creditors'
        rights generally and by general equitable principles.

             11.  Effectiveness.  This First Amendment shall become effective
   as of June 15, 1994 (the "Effective Date") when the following conditions
   shall have been met:

          (i)     the Agent shall have received counterparts hereof, duly

                  amended, supplemented or otherwise modified, has been
                  terminated and no obligations of AgriStor remain
                  thereunder;

        (iii)     the Agent shall have received written confirmation from
                  Canadian Imperial Bank of Commerce evidencing its

                  substantially in the form of Exhibit C;

                  executed by the Borrower; and 

         (vi)     the Agent shall have received an opinion of W. David
                  Romoser, General Counsel of the Borrower, substantially

   its obligation to pay all fees and disbursements of Simpson Thacher &
   Bartlett, special counsel for the Agent and the Banks, incurred in
   connection with this First Amendment.

             12.  Continuing Effect of Credit Agreement.  This First
   Amendment shall not constitute a waiver or amendment of any other
   provision of the Credit Agreement not expressly referred to herein and
   shall not be construed as a waiver or consent to any further or future
   action on the part of the Borrower or AgriStor Credit that would require a
   waiver or consent of the Banks or the Agent.  Except as expressly amended
   and waived hereby, the provisions of the Credit Agreement are and shall
   remain in full force and effect.

             13.  Counterparts.  This First Amendment may be executed by the

                                                             the Agreement]  


   To the Banks and the Agent
     Referred to Below
   c/o Chemical Bank,
     as Agent
   270 Park Avenue
   New York, New York  10017

   Dear Sirs:

             I have acted as counsel for A.O. Smith Corporation (the
   "Borrower") in connection with the Extension and First Amendment, dated as
   of June 15, 1994 (the "First Amendment"), to the Amended and Restated
   Credit Agreement (the "Credit Agreement") dated as of February 26, 1993
   among the Borrower, the banks listed on the signature pages thereof and
   Chemical Bank, as Agent.  Terms defined in the Credit Agreement are used
   herein as therein defined.

             I have examined originals or copies, certified or otherwise
   identified to my satisfaction, of such documents, corporate records,
   certificates of public officials and other instruments and have conducted
   such other investigations of fact and law as I have deemed necessary or
   advisable for purposes of this opinion.

             Upon the basis of the foregoing, I am of the opinion that:

             1.  Each of the Borrower and AgriStor Credit Corporation
   ("AgriStor") is a corporation duly incorporated, validly existing and in
   good standing under the laws of Delaware, and has all corporate powers and
   all material governmental licenses, authorizations, consents and approvals
   required to carry on its business as now conducted.

             2.  The execution, delivery and performance by the Borrower of
   the First Amendment and the Borrower Guarantee is within the Borrower's
   corporate powers, has been duly authorized by all necessary corporate
   action, requires no action by or in respect of, or filing with, any
   governmental body, agency or official and does not contravene, or
   constitute a default under, any certificate of incorporation or by-laws of
   the Borrower or, to the best of my knowledge, of any agreement, judgment,
   injunction, order, decree or other instrument binding upon the Borrower or
   result in the creation or imposition of any Lien on any asset of the
   Borrower or any of its Subsidiaries.

             3.  The execution, delivery and performance by AgriStor Credit
   of the First Amendment and the AgriStor Notes is within AgriStor Credit's
   corporate powers, has been duly authorized by all necessary corporate
   action, requires no action by or in respect of, or filing with, any
   governmental body, agency or official and does not contravene, or
   constitute a default under, any certificate of incorporation or by-laws of
   AgriStor Credit or, to the best of my knowledge, of any agreement,
   judgment, injunction, order, decree or other instrument binding upon
   AgriStor Credit or result in the creation or imposition of any Lien on any
   asset of AgriStor Credit or any of its Subsidiaries.

             4.  The First Amendment, the Borrower Guarantee and the AgriStor
   Notes constitute the valid and the binding obligations of the Borrower and
   AgriStor Credit enforceable in accordance with their terms, except as
   enforceability may be limited by applicable bankruptcy, insolvency,
   reorganization, moratorium or similar laws affecting the enforcement of
   creditors' rights generally and by general equitable principles.

             5.  Except as set forth in the Ilhardt, et al. v. A.O. Smith
   Corp., et al. lawsuit, there is no action, suit or proceeding pending
   against, or to the best of my knowledge threatened against or affecting,
   the Borrower or any of its Subsidiaries before any court or arbitrator or
   any governmental body, agency or official, in which there is a reasonable
   possibility of an adverse decision which could materially adversely affect
   the business, consolidated financial position or consolidated results of
   operations of the Borrower and its Consolidated Subsidiaries or AgriStor
   Credit, considered as a whole or which in any manner draws into question
   the validity of the First Amendment.

             6.  Each of the Borrower's Subsidiaries is a corporation validly
   existing and in good standing under the laws of its jurisdiction of
   incorporation, and has all corporate powers and all material governmental
   licenses, authorizations, consents and approvals required to carry on its
   business as now conducted.

                                      Very truly yours,

   
                                                                    EXHIBIT B


                                    GUARANTEE


             GUARANTEE, dated as of June 15, 1994, made by A.O. SMITH
   CORPORATION, a Delaware corporation (the "Guarantor"), in favor of
   CHEMICAL BANK, as agent (in such capacity, the "Agent") for the banks (the
   "Banks") parties to the Extension and First Amendment (as amended,
   supplemented or otherwise modified from time to time, the "First
   Amendment"), dated as of the date hereof, among AgriStor Credit
   Corporation ("AgriStor Credit")  the Guarantor, the Banks and the Agent,
   to the Amended and Restated Credit Agreement, dated as of February 26,
   1993 (as amended, supplemented or otherwise modified from time to time,
   the "Credit Agreement"), among the Guarantor, the Banks and the Agent.


                              W I T N E S S E T H:


             WHEREAS, pursuant to the First Amendment, the Banks have
   severally agreed to make AgriStor Loans to AgriStor Credit upon the terms
   and subject to the conditions set forth therein, to be evidenced by the
   AgriStor Notes issued by AgriStor Credit under the First Amendment;

             WHEREAS, it is a condition precedent to the obligation of the
   Banks to make their respective AgriStor Loans to AgriStor Credit under the
   First Amendment that the Guarantor shall have executed and delivered this
   Guarantee to the Agent for the ratable benefit of the Banks; and

             WHEREAS, Guarantor is the Parent of AgriStor Credit, and it is
   to the advantage of Guarantor that the Banks make the AgriStor Loans to
   AgriStor Credit.


             NOW, THEREFORE, in consideration of the premises and to induce
   the Agent and the Banks to enter into the First Amendment and to induce
   the Banks to make their respective loans to AgriStor Credit under the
   First Amendment, the Guarantor hereby agrees with the Agent, for the
   ratable benefit of the Banks, as follows:

             1.  Defined Terms.  (a)  Unless otherwise defined herein, terms
   defined in the First Amendment and used herein shall have the meanings
   given to them in the First Amendment.

             (b)  As used herein, "Obligations" means the collective
   reference to the unpaid principal of and interest on the AgriStor Notes
   and all other obligations and liabilities of AgriStor Credit to the Agent
   and the Banks (including, without limitation, interest accruing at the
   then applicable rate provided in the First Amendment after the maturity of
   the AgriStor Loans and interest accruing at the then applicable rate
   provided in the First Amendment after the filing of any petition in
   bankruptcy, or the commencement of any insolvency, reorganization or like
   proceeding, relating to AgriStor Credit whether or not a claim for post-
   filing or post-petition interest is allowed in such proceeding), whether
   direct or indirect, absolute or contingent, due or to become due, or now
   existing or hereafter incurred, which may arise under, out of, or in
   connection with, the First Amendment, the AgriStor Notes or any other
   document made, delivered or given in connection therewith, in each case
   whether on account of principal, interest, reimbursement obligations,
   fees, indemnities, costs, expenses or otherwise (including, without
   limitation, all fees and disbursements of counsel to the Agent or to the
   Banks that are required to be paid by AgriStor Credit or the Guarantor
   pursuant to the terms of the First Amendment or this Agreement or any
   other related document).

             (c)  The words "hereof," "herein" and "hereunder" and words of
   similar import when used in this Guarantee shall refer to this Guarantee
   as a whole and not to any particular provision of this Guarantee, and
   section and paragraph references are to this Guarantee unless otherwise
   specified.

             (d)  The meanings given to terms defined herein shall be equally
   applicable to both the singular and plural forms of such terms.

             2.  Guarantee.  (a) The Guarantor hereby unconditionally and
   irrevocably guarantees to the Agent, for the ratable benefit of the Banks
   and their respective successors, indorsees, transferees and assigns, the
   prompt and complete payment and performance by AgriStor Credit when due
   (whether at the stated maturity, by acceleration or otherwise) of the
   Obligations.

             (b)  The Guarantor further agrees to pay any and all expenses
   (including, without limitation, all fees and disbursements of counsel)
   which may be paid or incurred by the Agent or any Bank in enforcing, or
   obtaining advice of counsel in respect of, any rights with respect to, or
   collecting, any or all of the Obligations and/or enforcing any rights with
   respect to, or collecting against, the Guarantor under this Guarantee. 
   This Guarantee shall remain in full force and effect until the Obligations
   are paid in full and the Commitments are terminated, notwithstanding that
   from time to time prior thereto AgriStor Credit may be free from any
   Obligations.

             (c)  No payment or payments made by AgriStor Credit or any other
   Person or received or collected by the Agent or any Bank from AgriStor
   Credit or any other Person by virtue of any action or proceeding or any
   set-off or appropriation or application, at any time or from time to time,
   in reduction of or in payment of the Obligations shall be deemed to
   modify, reduce, release or otherwise affect the liability of the Guarantor
   hereunder which shall, notwithstanding any such payment or payments made
   by the Guarantor, or received or collected from the Guarantor, in respect
   of the Obligations pursuant to this Guarantee, remain liable for the
   Obligations until the Obligations are paid in full and the Commitments are
   terminated.

             (d)  The Guarantor agrees that whenever, at any time, or from
   time to time, it shall make any payment to the Agent or any Bank on
   account of its liability hereunder, it will notify the Agent and such Bank
   in writing that such payment is made under this Guarantee for such
   purpose.

             3.  Right of Set-off.  Upon the occurrence of any Event of
   Default, the Agent and each Bank is hereby irrevocably authorized at any
   time and from time to time without notice to the Guarantor, any such
   notice being expressly waived by the Guarantor, to set off and appropriate
   and apply any and all deposits (general or special, time or demand,
   provisional or final), in any currency, and any other credits,
   indebtedness or claims, in any currency, in each case whether direct or
   indirect, absolute or contingent, matured or unmatured, at any time held
   or owing by the Agent or such Bank to or for the credit or the account of
   the Guarantor, or any part thereof in such amounts as the Agent or such
   Bank may elect, against or on account of the obligations and liabilities
   of the Guarantor to the Agent or such Bank hereunder and claims of every
   nature and description of the Agent or such Bank against the Guarantor, in
   any currency, whether arising hereunder, under the First Amendment, any
   AgriStor Note or otherwise, as the Agent or such Bank may elect, whether
   or not the Agent or such Bank has made any demand for payment and although
   such obligations, liabilities and claims may be contingent or unmatured. 
   The Agent and each Bank shall notify the Guarantor promptly of any such
   set-off and the application made by the Agent or such Bank, as the case
   may be, of the proceeds thereof; provided that the failure to give such
   notice shall not affect the validity of such set-off and application.  The
   rights of the Agent and each Bank under this paragraph are in addition to
   other rights and remedies (including, without limitation, other rights of
   set-off) which the Agent or such Bank may have.

             4.  No Subrogation.  Notwithstanding anything to the contrary in
   this Guarantee, the Guarantor hereby irrevocably waives all rights which
   may have arisen in connection with this Guarantee to be subrogated to any
   of the rights (whether contractual, under the Bankruptcy Code, including
   Section 509 thereof, under common law or otherwise) of the Bank against
   AgriStor Credit or against any collateral security or guarantee or right
   of offset held by the Bank for the payment of the Obligations.  The
   Guarantor hereby further irrevocably waives all contractual, common law,
   statutory or other rights of reimbursement, contribution, exoneration or
   indemnity (or any similar right) from or against AgriStor Credit or any
   other Person which may have arisen in connection with this Guarantee.  So
   long as the Obligations remain outstanding, if any amount shall be paid by
   or on behalf of AgriStor Credit to the Guarantor on account of any of the
   rights waived in this paragraph, such amount shall be held by the
   Guarantor in trust, segregated from other funds of such Guarantor, and
   shall, forthwith upon receipt by such Guarantor, be turned over to the
   Agent in the exact form received by the Guarantor (duly indorsed by the
   Guarantor to the Agent, if required), to be applied against the
   Obligations, whether matured or unmatured, in such order as the Agent may
   determine.  The provisions of this paragraph shall survive the termination
   of this Guarantee and the payment in full of the Obligations and the
   termination of the Commitments.

             5.  Amendments, etc. with respect to the Obligations; Waiver of
   Rights.  The Guarantor shall remain obligated hereunder notwithstanding
   that, without any reservation of rights against the Guarantor, and without
   notice to or further assent by the Guarantor, any demand for payment of
   any of the Obligations made by the Agent or any Bank may be rescinded by
   the Agent or such Bank, and any of the Obligations continued, and the
   Obligations, or the liability of any other party upon or for any part
   thereof, or any collateral security or guarantee therefor or right of
   offset with respect thereto, may, from time to time, in whole or in part,
   be renewed, extended, amended, modified, accelerated, compromised, waived,
   surrendered or released by the Agent or any Bank, and the First Amendment,
   any AgriStor Notes, and any other documents executed and delivered in
   connection therewith may be amended, modified, supplemented or terminated,
   in whole or in part, as the Agent (or the Required Banks, as the case may
   be) may deem advisable from time to time, and any collateral security,
   guarantee or right of offset at any time held by the Agent or any Bank for
   the payment of the Obligations may be sold, exchanged, waived, surrendered
   or released.  Neither the Agent nor any Bank shall have any obligation to
   protect, secure, perfect or insure any Lien at any time held by it as
   security for the Obligations or for this Guarantee or any property subject
   thereto.  When making any demand hereunder against the Guarantor, the
   Agent or any Bank may, but shall be under no obligation to, make a similar
   demand on AgriStor Credit or any other guarantor, and any failure by the
   Agent or any Bank to make any such demand or to collect any payments from
   AgriStor Credit or any such other guarantor or any release of AgriStor
   Credit or such other guarantor shall not relieve the Guarantor of its
   obligations or liabilities hereunder, and shall not impair or affect the
   rights and remedies, express or implied, or as a matter of law, of the
   Agent or any Bank against the Guarantor.  For the purposes hereof "demand"
   shall include the commencement and continuance of any legal proceedings.

             6.  Guarantee Absolute and Unconditional.  The Guarantor waives
   any and all notice of the creation, renewal, extension or accrual of any
   of the Obligations and notice of or proof of reliance by the Agent or any
   Bank upon this Guarantee or acceptance of this Guarantee; the Obligations,
   and any of them, shall conclusively be deemed to have been created,
   contracted or incurred, or renewed, extended, amended or waived, in
   reliance upon this Guarantee; and all dealings between AgriStor Credit or
   the Guarantor, on the one hand, and the Agent and the Banks, on the other,
   shall likewise be conclusively presumed to have been had or consummated in
   reliance upon this Guarantee.  The Guarantor waives diligence,
   presentment, protest, demand for payment and notice of default or
   nonpayment to or upon AgriStor Credit or the Guarantor with respect to the
   Obligations.  This Guarantee shall be construed as a continuing, absolute
   and unconditional guarantee of payment without regard to (a) the validity,
   regularity or enforceability of the First Amendment, any AgriStor Note, or
   any other document executed in connection therewith, any of the
   Obligations or any other collateral security therefor or guarantee or
   right of offset with respect thereto at any time or from time to time held
   by the Agent or any Bank, (b) any defense, set-off or counterclaim (other
   than a defense of payment or performance) which may at any time be
   available to or be asserted by AgriStor Credit against the Agent or any
   Bank, or (c) any other circumstance whatsoever (with or without notice to
   or knowledge of AgriStor Credit or the Guarantor) which constitutes, or
   might be construed to constitute, an equitable or legal discharge of
   AgriStor Credit for the Obligations, or of the Guarantor under this
   Guarantee, in bankruptcy or in any other instance.  When pursuing its
   rights and remedies hereunder against the Guarantor, the Agent and any
   Bank may, but shall be under no obligation to, pursue such rights and
   remedies as it may have against AgriStor Credit or any other Person or
   against any collateral security or guarantee for the Obligations or any
   right of offset with respect thereto, and any failure by the Agent or any
   Bank to pursue such other rights or remedies or to collect any payments
   from AgriStor Credit or any such other Person or to realize upon any such
   collateral security or guarantee or to exercise any such right of offset,
   or any release of AgriStor Credit or any such other Person or of any such
   collateral security, guarantee or right of offset, shall not relieve the
   Guarantor of any liability hereunder, and shall not impair or affect the
   rights and remedies, whether express, implied or available as a matter of
   law, of the Agent or any Bank against the Guarantor.  This Guarantee shall
   remain in full force and effect and be binding in accordance with and to
   the extent of its terms upon the Guarantor and its successors and assigns
   thereof, and shall inure to the benefit of the Agent and the Banks, and
   their respective successors, indorsees, transferees and assigns, until all
   the Obligations and the obligations of the Guarantor under this Guarantee
   shall have been satisfied by payment in full and the Commitments shall be
   terminated, notwithstanding that from time to time during the term of the
   First Amendment AgriStor Credit may be free from any Obligations.

             7.  Reinstatement.  This Guarantee shall continue to be
   effective, or be reinstated, as the case may be, if at any time payment,
   or any part thereof, of any of the Obligations is rescinded or must
   otherwise be restored or returned by the Agent or any Bank upon the
   insolvency, bankruptcy, dissolution, liquidation or reorganization of
   AgriStor Credit or upon or as a result of the appointment of a receiver,
   intervenor or conservator of, or trustee or similar officer for, AgriStor
   Credit or any substantial part of its property, or otherwise, all as
   though such payments had not been made.

             8.  Payments.  The Guarantor hereby agrees that the Obligations
   will be paid to the Agent without set-off or counterclaim in U.S. Dollars
   at the office of the Agent located at 270 Park Avenue, New York, New York
   10017.

             9.  Representations and Warranties.  The Guarantor represents
   and warrants to the Agent and the Banks that:

             (a)  the Guarantor has the corporate power and authority and the
   legal right to execute and deliver, and to perform its obligations under,
   this Guarantee, and has taken all necessary corporate action to authorize
   its execution, delivery and performance of this Guarantee; and

             (b)  this Guarantee constitutes a legal, valid and binding
   obligation of the Guarantor enforceable in accordance with its terms,
   except as affected by bankruptcy, insolvency, fraudulent conveyance,
   reorganization, moratorium and other similar laws relating to or affecting
   the enforcement of creditors' rights generally, general equitable
   principles and an implied covenant of good faith and fair dealing.

             The Guarantor agrees that the foregoing representations and
   warranties shall be deemed to have been made by the Guarantor on the date
   of each borrowing by AgriStor Credit under the First Amendment on and as
   of such date of borrowing as though made hereunder on and as of such date.

             10.  Authority of Agent.  The Guarantor acknowledges that the
   rights and responsibilities of the Agent under this Guarantee with respect
   to any action taken by the Agent or the exercise or non-exercise by the
   Agent of any option, right, request, judgment or other right or remedy
   provided for herein or resulting or arising out of this Guarantee shall,
   as between the Agent and the Banks, be governed by the First Amendment and
   by such other agreements with respect thereto as may exist from time to
   time among them, but, as between the Agent and the Guarantor, the Agent
   shall be conclusively presumed to be acting as agent for the Banks with
   full and valid authority so to act or refrain from acting, and the
   Guarantor shall not be under any obligation, or entitlement, to make any
   inquiry respecting such authority.

             11.  Notices.  All notices, requests and demands to or upon the
   Agent, any Bank or the Guarantor to be effective shall be made in the
   manner provided for in subsection 9.1 of the Credit Agreement.  The Agent,
   each Bank and the Guarantor may change its address and transmission
   numbers for notices by notice in the manner provided in the Credit
   Agreement.

             12.  Severability.  Any provision of this Guarantee which is
   prohibited or unenforceable in any jurisdiction shall, as to such
   jurisdiction, be ineffective to the extent of such prohibition or
   unenforceability without invalidating the remaining provisions hereof, and
   any such prohibition or unenforceability in any jurisdiction shall not
   invalidate or render unenforceable such provision in any other
   jurisdiction.

             13.   Integration.  This Guarantee represents the agreement of
   the Guarantor with respect to the subject matter hereof and there are no
   promises or representations by the Agent or any Bank relative to the
   subject matter hereof not reflected herein.

             14.   Amendments in Writing; No Waiver; Cumulative Remedies. 
   (a)  None of the terms or provisions of this Guarantee may be waived,
   amended, supplemented or otherwise modified except by a written instrument
   executed by the Guarantor and the Agent, provided that any provision of
   this Guarantee may be waived by the Agent and the Banks in a letter or
   agreement executed by the Agent or by telex or facsimile transmission from
   the Agent.

             (b)  Neither the Agent nor any Bank shall by any act (except by
   a written instrument pursuant to paragraph 14(a) hereof), delay,
   indulgence, omission or otherwise be deemed to have waived any right or
   remedy hereunder or to have acquiesced in any Default or Event of Default
   or in any breach of any of the terms and conditions hereof.  No failure to
   exercise, nor any delay in exercising, on the part of the Agent or any
   Bank, any right, power or privilege hereunder shall operate as a waiver
   thereof.  No single or partial exercise of any right, power or privilege
   hereunder shall preclude any other or further exercise thereof or the
   exercise of any other right, power or privilege.  A waiver by the Agent or
   any Bank of any right or remedy hereunder on any one occasion shall not be
   construed as a bar to any right or remedy which the Agent or such Bank
   would otherwise have on any future occasion.

             (c)  The rights and remedies herein provided are cumulative, may
   be exercised singly or concurrently and are not exclusive of any other
   rights or remedies provided by law.

             15.  Section Headings.  The section headings used in this
   Guarantee are for convenience of reference only and are not to affect the
   construction hereof or be taken into consideration in the interpretation
   hereof.
