Borrower agrees to pay interest on the outstanding principal amount of the Revolving Credit Loan at the rate and at the time specified in the Revolving Credit Note. Each change in the interest rates due to a change in the Prime Rate shall take effect simultaneously with the corresponding change in the Prime Rate. Interest may be charged to Borrower’s loan account as an Advance at Lender’s option, whether or not Borrower then has a right to obtain an Advance pursuant to the terms of this Agreement.
