Furthermore, each Reporting Person hereby disclaims on this basis beneficial ownership of any shares of Common Stock underlying the Warrant.

	Without limiting the generality of the foregoing, the filing of this Schedule 13G shall not be construed as an admission that (a) either of the Reporting Persons are, for purposes of Section 13(d) or 13(g) of the Act, the beneficial owner of any equity securities covered by this Schedule 13G or (b) that this Schedule 13G is legally required to be filed by each of the Reporting Persons.

On this basis, each Reporting Person hereby disclaims beneficial ownership as to such shares, as set forth in response to Item 4(a) above.
