Within the limits of the Commitment the Borrower may borrow, repay or prepay and reborrow under this letter agreement (the "Agreement"). This Facility shall at all times be secured by a perfected first ranking security interest in the Borrower's accounts receivable pursuant to the terms and conditions in the Bank's Security Agreement (as defined below). Subject to the terms and conditions of this Agreement, this Commitment may be utilized by the Borrower in the form of loans and/or letters of credit provided that the aggregate principal amount of loans outstanding at any one time, credit extensions by way of letters of credit, and unreimbursed drawings under letters of credit does not exceed US$20,000,000.00. I. LOANS 1. Domestic dollar loans bearing a per annum interest rate equal to the Bank's floating Base Rate (as defined in the attached note); such loans shall be evidenced by a note in the form of Exhibit A hereto (the "Note"). 2. Alternatively, the Borrower may request the Bank to make, and, subject to the satisfaction of the conditions precedent herein contained the Bank shall make, one or more Eurodollar loans in minimum amounts of $1,000,000 and multiples of $100,000 in excess thereof thereafter with interest periods (each an "Interest Period") up to one year in duration as requested by the Borrower in the notice of borrowing (such notice in the form of Exhibit G attached hereto, a "Notice of Borrowing") delivered by the Borrower in connection with such loan and agreed to by the Bank. The precise duration of each Interest Period requested will be calculated by the Bank according to its Eurodollar practices; provided that no Interest Period shall end after the Final Maturity Date. Eurodollar loans shall bear a per annum interest rate at a margin of 0.60 percent in excess of the rate at which Deutsche Bank AG Cayman Islands Branch can obtain U.S. Dollar deposits for the Interest Period requested, in the New York Market during New York business hours. Interest shall be based on the bank basis of a year of 360 days and the exact number of days elapsed. Such loans shall be evidenced by the Note. 2 2 II. LETTERS OF CREDIT Documentary and standby letters of credit, the terms and charges with respect to which letters of credit will be mutually agreed upon on a case-by-case basis. Such letters of credit will be subject to our commissions, fees and out-of-pocket expenses as negotiated on a case-by-case basis. In addition to the documents required pursuant to Section V below, the Borrower shall have, prior to the issuance of a letter of credit, supplied the Bank with (i) a duly completed application (specimen attached as Exhibit F) and (ii) the respective text, in form and substance satisfactory to the Bank, of the proposed standby letter of credit. Subject to the terms of this Agreement, each letter of credit transaction will be handled in accordance with the Bank's usual practice. Effective as of the date hereof, (i) the CAD$3,000,000 letter of credit (Number: 839-53110), issued by the Bank for the account of the Borrower on September 26, 1994 (the "Canadian Letter of Credit") shall be deemed issued and outstanding under the Facility, (ii) the Borrower's rights and obligations with respect to the Canadian Letter of Credit shall be governed by the Loan Documents, and (iii) the Borrower's obligations with respect to such letter of credit shall be secured by the Collateral (as defined in the Security Agreement). For purposes of any calculation of the amounts outstanding under the Facility required to be made hereunder on any day (including, without limitation, any calculation of outstanding obligations for purposes of determining the amount of usage of the Commitment or for purposes of determining compliance with financial ratios), the Bank will compute the United States Dollar equivalent of the Canadian dollar obligations of the Bank with respect to the Canadian Letter of Credit using a rate of exchange equal to the rate of exchange which in accordance with normal banking procedures the Bank could purchase Canadian dollars with United States Dollars on such day. III. ORIGINATION FEE/COMMITMENT FEE The Borrower agrees to pay to the Bank the following: 1. A one-time up-front fee in the amount of US$10,000.00, which shall be due and payable on the date this Agreement is signed by the Borrower; 2. A commitment fee (the "Commitment Fee") of 0.125% per annum of the average daily unused portion of the Commitment, commencing on the date this Agreement is signed by the Borrower.
