In addition, the Amendment amends the Company's liquidity covenant to extend the requirement for $2.5 million in excess availability through the full term of the Credit Agreement and amends the applicable definition of EBITDA to provide an aggregate allowance for restructuring charges in the amount of $1.5 million in fiscal 2009. The Amendment also provides for a $100,000 amendment fee.
