SCHEDULE 13D




Comment for Type of Reporting Person:
The number of shares of Common Stock beneficially owned by the Reporting Person consists of (i) 177,789 shares of Common Stock and (ii) an aggregate of 88,635 shares of Common Stock underlying warrants that are currently exercisable (subject to the Beneficial Ownership Limitation (as defined below)). The provisions of the warrants restrict the exercise of such warrants to the extent that, upon such exercise, the number of shares of Common Stock then beneficially owned by the holder and its affiliates and any other person or entities with which such holder would constitute a Section 13(d) "group" would exceed 9.99% of the total number of shares of Common Stock then outstanding (the "Beneficial Ownership Limitation"). Accordingly, notwithstanding the number of shares reported, the reporting person disclaims beneficial ownership of the shares of Common Stock issuable upon the exercise of such warrants to the extent that upon such exercise the number of shares beneficially owned by all reporting persons hereunder, in the aggregate, would exceed the Beneficial Ownership Limitation.
