H.C. Wainwright & Co. acted as the exclusive placement agent for the offering.

The aggregate gross proceeds to the Company from the offering were approximately $4.25 million, before deducting the placement agent’s fees and other offering expenses payable by the Company. The potential additional gross proceeds to the Company from the short-term unregistered warrants, if fully exercised on a cash basis, will be approximately $4.1 million. No assurance can be given that any of such short-term unregistered warrants will be exercised. The Company intends to use the net proceeds from this offering primarily for working capital and general corporate purposes.
