          Section 11.9) as a result of the non-satisfaction or non-waiver of one
          or more of the conditions contained in Section 7.1, and the
          non-satisfaction of such condition or conditions does not result
          principally from the inaccuracy of any representation or warranty of
          Buyer or ISG, or the breach of any material covenant by Buyer or ISG,
          in either case first occurring after May 5, 2004."
