105 PROCEDURES LETTER-FLOATING AND FIXED RATE LOANS Harris Trust and Savings Bank 111 West Monroe Street Chicago, Illinois 60690 Gentlemen: Oil-Dri Corporation of America, a Delaware corporation (the "COMPANY") hereby requests that borrowings under its $15,000,000 line of credit granted by Harris Trust and Savings Bank be made and documented upon the following terms and conditions. All borrowings made by us under our line of credit from you shall bear interest prior to maturity either (i) at a rate per annum which is equal at all times to the rate from time to time announced by you as your prime commercial rate, with any change in the interest rate on such borrowings by virtue of a change in such prime commercial rate to be and become effective as of and on the date of the relevant change in such prime commercial rate (such borrowings being hereinafter collectively referred to as the "FLOATING RATE Loans" and individually as a "FLOATING RATE LOAN") or (ii) at our request, if you so agree, at a short term fixed rate of interest on and subject to the terms hereinafter set forth (such borrowings being hereinafter collectively referred to as the "FIXED RATE LOANS" and individually as a "FIXED RATE LOAN"). The Floating Rate Loans and the Fixed Rate Loans are sometimes hereinafter collectively referred to as the "LOANS" and individually as a "LOAN". You will from time to time receive telephonic requests for Fixed Rate Loans from any one of the persons authorized to borrow on our behalf under the terms of this letter, each such request to specify the amount and term of the requested Fixed Rate Loan. If you are willing to make a Fixed Rate Loan available to us for the amount and for the term requested, you shall advise the requesting person of the interest rate at which you are prepared to make such Fixed Rate Loan and if the person acting on our behalf indicates that such rate is acceptable, the Loan shall be deemed consummated. Each Fixed Rate Loan shall be in a minimum amount of $1,000,000.00 and shall mature upon demand, but prior to demand, shall mature on the last day of the period for which the interest rate applicable to such Fixed Rate Loan shall have been fixed (each such period being hereinafter referred to as an "INTEREST PERIOD".) We acknowledge and agree that you have no obligation to quote rates or to make or refund any Fixed Rate Loan after receiving a request therefor from us and that any Fixed Rate Loan made by you to us shall be subject to such other terms and conditions as are mutually agreed upon between you and us. 106 We agree that no Fixed Rate Loan may be voluntarily prepaid prior to its express maturity date. In the event you shall incur any loss, cost or expense (including, without limitation, any loss of profit and any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by you to fund or maintain any Fixed Rate Loan or the relending or reinvesting of such deposits or amounts paid or prepaid by us) as a result of any payment, (whether voluntary or as a result of a demand hereunder) of a Fixed Rate Loan on a date other than the last day of the Interest Period applicable thereto, then upon your demand, we shall pay you such amounts as will reimburse you for such loss, cost or expense. If you make such a claim for compensation, you shall provide to us a certificate setting forth the amount of such loss, cost or expense in reasonable detail and such certificates shall be conclusive and binding on us as to the amount thereof except in the case of manifest error. All borrowings made by us under our line of credit from you shall be payable on demand but if no demand is made, each such borrowing shall automatically mature (i) on the last day of the Interest Period applicable thereto in the case of Fixed Rate Loans and (ii) in the case of Floating Rate Loans, on the interest payment date next following the date the Floating Rate Loan is made, provided that, the Floating Rate Loans will automatically be refunded with new Floating Rate Loans maturing on demand but if no demand is made, then on the interest payment date next following the date such new Floating Rate Loan is made, unless the line of credit has been terminated or expired or you have advised us that you do not desire to effect such a renewal. Interest on all borrowings hereunder shall be computed on the basis of a year of 360 days and actual days elapsed and shall be payable, in the case of Floating Rate Loans, on the 25th day of each month, and in the case of Fixed Rate Loans, on the last day of their Interest Period and, if such Interest Period is longer than three (3) months, every three (3) months after the Loan is made, and, in the case of all Loans, upon demand. In the event that the Company fails to pay any portion of a Loan when due (whether by lapse of time, upon demand or otherwise), such unpaid amount shall thereafter bear interest, which the Company hereby promises to pay at your offices in Chicago, Illinois, at a rate per annum which is equal at all times to the greater of (i) the rate per annum determined by adding three percent (2%) to the rate applicable to such Loan prior to maturity or, (ii) the rate per annum determined by adding three percent (2%) to the rate from time to time announced by you as your prime commercial rate. All borrowings hereunder shall be made against and evidenced by a promissory note of the Company payable to your order in the aggregate principal amount of $15,000,000, such note to mature upon demand, and to be otherwise in the form of Exhibit A attached hereto (the "NOTE"). All borrowings made hereunder, the status of such borrowings as Floating Rate Loans or Fixed Rate Loans, the rates of interest and Interest Periods applicable to Fixed Rate Loans and the repayment of any principal of the borrowings hereunder shall be recorded by you on your books and records or, at your option, endorsed on the reverse side of the Note or on a schedule thereto and the unpaid principal balance, status and interest rates at any time so recorded or endorsed shall be prima facie evidence in any court or other proceedings brought to enforce the Note of the amount remaining unpaid thereon, the interest rate applicable thereto and the status of Loans evidenced thereby. 107 You agree until further notice that upon oral advice by telephone received by you from time to time from authorized persons listed in this letter that we wish to borrow money, you will, lend and deposit to our general account with you, known as Account Number 367-985-9 (the "ACCOUNT") such sums of money as may be mutually agreed upon.
