This interest rate may change on October l) 2022, and eve1y day thereafter. Each date on which the interest rate may change is called the "Change Date." Prior to each Change Date, Lender will calculate the new interest rate based on Prime Rate as published in the Wall Street Journal in effect on the Change Date (the ¹¹Index¹¹) plus 0.000 percentage points (the "Margin¹¹), The interest rate will never be greater than 20.000% or less than 3.990%.

If the Index is not available at the time of the Change Date) Lender will choose a new Index which is based on comparable information. The Index is used solely to establish a base from which tile actual rate of interest payable under the Agreement will be calculated, and is not a reference to any actual rate of interest charged by any lender to any particular borrower.

Nothing contained herein shall be construed as to require the Borrower to pay interest at a greater rate than the maximum allowed by law.

An increase in the interest rate will result in a higher payment amount. Interest on this Agreement is calculated on an Actual/360 day basis. This calculation method results in a higher effective interest rate than the numeric interest rate stated in this Agreement.

LATE PAYMENT CHARGE. If any required payment is more than 10 days late, then at Lender's option, Lender will assess a late payment charge of 5.000% of the amount of the regularly scheduled payment then past due, subject to a maximum charge of $1)000.00 and a 1ninimum charge of $30.00.
