On April 14, 2004, the Company amended and restated its May 12, 2002 Loan and Security Agreement with Fleet Capital Corporation, as Agent. The Amended and Restated Loan and Security Agreement incorporates the subsequent seven amendments and further amends the agreement to include, among other things, a total facility of $60 million, consisting of the existing $40 million revolving line of credit and a $20 million term loan. The outstanding borrowing under the term loan was increased from $18.5 million to $20 million, with reduced quarterly amortization.
