      applicable grace period with respect thereto, if any) or performance or
      observance of any indebtedness in excess of $2,500,000 (other than
      indebtedness outstanding under this Agreement or the Credit Agreement) or
      the 2008 Senior Notes or the 2009 Senior Notes, or any other event or
      condition shall occur or condition exist, the effect of which default or
      other event or condition is to cause, or permit, the holder or holders of
      such indebtedness (or trustee or agent on behalf of such holders) to cause
      (determined without regard to whether any notice or lapse of time is
      required), any such indebtedness to become due prior to its stated
      maturity; or (ii) any such indebtedness shall be declared due and payable,
      or required to be prepaid other than by a regularly scheduled required
      prepayment, prior to the stated maturity thereof;"

      12.   All references to the "Consignment, Forward Contracts and Trading
