        Section 4.  No Default.  The Company hereby represents and warrants to
the Lenders that, both immediately prior to the effectiveness of this Waiver
and also after giving effect thereto, no Default shall have occurred and be
continuing.

execute and deliver this Waiver by signing any such counterpart and sending the
same by telecopier, mail, messenger or courier to the Administrative Agent or
