LNFG might be deemed the "beneficial owners" of some or all of the
securities to which this Schedule relates in that they might be deemed to
share the power to direct the voting or disposition of such securities.
Neither the filing of this Schedule nor any of its contents shall be deemed
to constitute an admission that any of such individuals is, for any
purpose, the beneficial owner of any of the securities to which this
Schedule relates, and such beneficial ownership is expressly disclaimed.
