otherwise, the beneficial owner of such shares. The Reporting Persons may be
deemed to constitute a "group" for purposes of Section 13(d)(3) of the Act.
Pursuant to Rule 13d-4 of the Act, the Reporting Persons expressly declare that
the filing of this statement shall not be construed as an admission that any
such person is, for the purposes of Section 13(d) and/or Section 13(g) of the
Act or otherwise, the beneficial owner of any securities covered by this
statement held by any other person. The Reporting Persons expressly disclaim
that they have agreed to act as a group other than as described in this Schedule
13G.

           (b) Percent of class:

           See Item 11 of each of pages 2-11 for the percent of class
beneficially owned by each of the Reporting Persons. All ownership percentages
of the securities reported herein are based upon 8,439,741 shares of Common
Stock outstanding as of immediately after the Issuer's initial public offering,
as disclosed in the Issuer's prospectus filed pursuant to Rule 424(b)(4) of the
Securities Act of 1933 with the Securities and Exchange Commission on November
