(1) Under the terms of the facility, loans are Prime Rate Loans, unless we elect LIBOR Loans. If a LIBOR Loan is not renewed at maturity it automatically converts to a Prime Rate Loan.

(2) The “base rate” is the highest of the prime rate established by the Agent, or one-month LIBOR plus 1%, or the federal funds effective rate plus 0.5%.
