      4(c) of the BGL Agreement, BGLS shall make or cause to be made to High
      River Group such payment within twenty (20) days after receiving the
      Arbitrator's notice of decision. In the event that BGLS fails to make such
      payment within twenty (20) days after receipt of the Arbitrator's notice
      of decision, BGLS shall immediately pay or cause to be paid to High River
      Group an additional sum in the amount of $50 million.

         notwithstanding, High River shall have no obligation with

         solicitation of Written Consents or Proxies."
