Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Issued by the Company to the Reporting Person on 6/28/2007.Pursuant to Section 2(d) of the Warrant, the Reporting Person does not have the right to exercise any portion of the Warrant after the Initial Excercise Date (12/29/2007)to the extent that, after giving effect to such exercise,the Reporting Person would beneficially own in excess of the Beneficial Ownership Limitation(4.99% of the shares outstanding immediately after such exercise).In addition, Section 2(d)ofthe Warrant further provides that the Reporting Person can waive the Beneficial Ownership Limitation of 4.99% and increase it to 9.99%,with 61 days notice to the Company,but the Beneficial Ownership Limitation may not be further waived.The Reporting Person has not provided notice of such waiver to the Company.Accordingly,for purposes of calculating when J.P.Morgan Ventures Corp. became a 10% beneficial owner of the Issuer's common equity securities,the Reporting Person is not the beneficial owner of the Warrants.
(2) Conversion ratio of one warrant into one share of Common Stock
