Under the NYSE’s rules, if the Company determines that, if necessary, it will cure the stock price deficiency by taking an action that will require stockholder approval, it must so inform the NYSE in the above referenced notification and the price condition will be deemed cured if the price promptly exceeds $1.00 per share, and the price remains above that level for at least the following 30 trading days. The Company intends to consider available alternatives, including but not limited to a reverse stock split, that are subject to shareholder approval.

The Company’s common stock will continue to be listed and trade on the NYSE during this period, subject to the Company’s compliance with other NYSE continued listing standards.
