Section  12  of  the  Loan  Agreement  and Covenants (A) and (E) of Supplement A

Division  of at least ($5,000,000) as of December 31, 2000.  Borrower represents

Events  of  Default  that  exists  under  the  Loan Agreement and the other Loan
Documents  as  of the date hereof.  Lender hereby waives the Designated Defaults
in  existence  on  the  date hereof.  In no event shall such waiver be deemed to
constitute  a waiver of (a) any Default Condition or Event of Default other than
the  Designated  Defaults  in  existence  on  the  date of this Amendment or (b)

contracts  between the parties, Borrower hereby agrees that it shall be required
strictly  to comply with all of the terms of the Loan Documents on and after the
date  hereof.

     5.     RATIFICATION  AND  REAFFIRMATION.  Borrower  hereby  ratifies  and
            --------------------------------

Obligations  are  owing and payable without defense, offset or counterclaim (and
to  the extent there exists any such defense, offset or counterclaim on the date
hereof, the same is hereby waived by Borrower); the security interests and liens
