Explanation of Responses:

1. The terms of the Series A Convertible Preferred Stock contain a limitation on conversion which prevents the Reporting Person from converting shares of Series A Convertible Preferred Stock into shares of Common Stock if, after giving effect to the conversion, the Reporting Person would beneficially own more than 4.99% of the outstanding shares of Common Stock. The Reporting Person may elect to increase this limitation to 9.99%, 14.99% or 19.99%, upon not less than 61 days prior written notice to the Company. The Reporting Person disclaims beneficial ownership of such securities except to the extent of the Reporting Person's pecuniary interest in such securities.

2. The Series A Convertible Preferred Stock has no expiration date.

3. The individual elected cashless exercise as allowed by affiliates of the Company, thereby receiving fewer preferred shares.
