Accordingly, WIAP is no longer a member of the Section 13(d) group and will cease to be a Reporting Person immediately after the filing of this statement. The remaining Reporting Persons will continue filing as a group statements on Schedule 13D with respect to their beneficial ownership of securities of the Issuer, to the extent required by applicable law.
