      in accordance with its terms except as such enforceability may be limited
      by bankruptcy, insolvency, reorganization, moratorium or other similar
      laws affecting creditors' rights generally and by general principles of
      equity (regardless of whether such enforceability is considered in a
      proceeding at law or in equity).

            (b) After giving effect to this Amendment, the representations and
      warranties set forth in Article III of the Credit Agreement are true and
      correct in all material respects on and as of the date hereof with the

waiver, amendment, modification or other change of, any of the terms,
conditions, obligations, covenants or agreements contained in the Credit
Agreement or any other Loan Document in similar or different circumstances.
After the date hereof, any reference to the Credit Agreement shall mean the
