In no event shall the interest charged or paid hereunder exceed the highest maximum rate allowed by applicable law ("Highest Lawful Rate"). The Index is not necessarily the lowest rate charged by Lender on its loans and Borrower understands that Lender may make loans based on other rates as well. If the Index becomes unavailable during the term of this note, Lender may designate a substitute index after notice to Borrower. Lender will provide Borrower with the current Index rate upon Borrower's request. Notwithstanding the foregoing, at no time shall the interest charged be less than four percent (4%) per annum, nor more than the lesser of eighteen percent (18%) per annum or the Highest Lawful Rate.
