Explanation of Responses:

1. Millennium Management, L.L.C., a Delaware limited liability company ("Millennium Management"), is the manager of Millenco, L.L.C. (Millenco), and consequently may be deemed to have shared voting control and investment discretion over securities owned by Millenco. Israel A. Englander ("Mr. Englander") is the managing member of Millennium Management. As a result, Mr. Englander may be deemed to have shared voting control and investment discretion over securities deemed to be beneficially owned by Millennium Management. The foregoing should not be construed in and of itself as an admission by Millennium Management or Mr. Englander as to beneficial ownership of the shares owned by Millenco. Each of the Reporting Persons disclaims beneficial ownership of the shares of Common Stock to the extent such beneficial ownership exceeds such Reporting Person's pecuniary interest.

2. The Warrants may not be exercised until such time as the Reporting Persons would not beneficially own after any such exercise more than 4.99% of the outstanding shares of Common Stock.
