The base rate is the highest of (a) PNC Bank's prime rate, (b) the Federal Funds Rate plus 0.50% or (c) the daily LIBOR rate, as defined in the underlying Credit Agreement, plus 1.00%. The base rate spread ranges from 0.00% to 1.00%. LIBOR-based rates are determined by dividing the published LIBOR rate by a number equal to 1.00 minus the percentage prescribed by the Federal Reserve for determining the maximum reserve requirements with respect to any Eurocurrency funding by banks on such day. The LIBOR-based rate spread ranges from 1.00% to 2.00%. |  | . The interest rate on this facility is the financial institution's base rate plus 1.50%. | .

If no drawings on the facility exist, dividends, distributions, and redemptions in excess of $15,000 per year are subjected to a limitation of $75,000 in the aggregate. The $75,000 aggregate limitation also includes certain loans, investments, and acquisitions.
