Explanation of Responses:

Remarks:
An initial Form 3 was filed based on the firm holding 1,109,379 warrants, which constituted a 14% ownership of the outstanding warrants. At the time, the warrants had become exercisable within 60 days and on an as converted basis, when added to the Firm's existing holdings in the common stock, the Firm had beneficial ownership of less than 1% of the outstanding common stock of the issuer. As the warrants themselves were non-voting and constituted derivative instruments, in line with the guidance in the adopting release for the 1991 Section 16 amendments the treatment of the warrants as their own class of equity securities for purposes of 16(a) was made in error. Therefore, the firm's Form 3 was filed in error.
No securities are beneficially owned.
