in negotiations to obtain replacement financing for its existing revolving
credit agreement with National City Bank which expires on December 31,
2009.&#160;&#160;The Company has been informed by its independent registered
public accounting firm that without replacement financing to satisfy the
auditors' concerns regarding the Company's liquidity and debt covenant margins,
their audit opinion will include an explanatory paragraph indicating substantial
doubt about the Company's ability to continue as a going concern.&#160;&#160;In

required commitment of the Company's finance personnel and resources that would

Credit Agreement, the Company is unable to file such report within the
prescribed time without unreasonable effort or expense. Nevertheless, the
