Amount beneficially owned: As of December 31, 2006 the reporting person beneficially owned 1,222,960 shares of the issuer’s Common Stock.

The reporting person acquired the shares beneficially owned by him prior to the registration of the issuer’s Common Stock under Section 12 of the Act, or in transactions exempt from reporting requirements pursuant to Section 13(d)(6)(A) of the Act, and, accordingly, is filing this Schedule 13G pursuant to Rule 13d-1(d) under the Act.
