obligations, covenants or agreements contained in the Credit Agreement or any
other Loan Document, all of which are ratified and affirmed in all respects and

other change of, any of the terms, conditions, obligations, covenants or
agreements contained in the Credit Agreement in similar or different
circumstances. This Agreement shall apply and be effective only with respect to
the provisions of the Credit Agreement specifically referred to herein. Upon
