        Walker Smith Capital (and its affiliates) ("Walker Smith") and Capital Ventures
        International ("CVI")
.
        The
        Company is party to certain
Stock
        and
        Warrant Purchase Agreements dated November 24, 2004 (the "Purchase Agreements")
        with each of SF Capital, BayStar, Walker Smith and CVI. Pursuant to the terms
        of
