5. Note Payable to Financial Institution

At March 31, 2012, the Company had a $115.0 million line of credit agreement, under which $53.8 million was outstanding bearing interest at a weighted average rate of 2.89%. The Company had additional net borrowing capacity under the line of credit of $58.0 million at March 31, 2012. The line of credit bears interest at rates related to LIBOR plus 2.50% to 4.50%, or the lending institution's prime rate plus 1.50% to 3.50%. We were able to borrow at LIBOR plus 2.5% under the credit agreement at March 31, 2012. During the first quarter of 2012, we entered into the Ninth Amendment to our Amended and Restated Credit Agreement ("Credit Agreement"). The Amendment extended the expiration date to April 30, 2013, set the aggregate commitment of the lenders at $115 million, and made certain changes in the definition, method of calculation and amounts of certain covenants. The Company was in compliance with its financial covenants as of March 31, 2012.
