Each of Agri-Energy and Gevo shall indemnify and hold harmless TriplePoint from and against any claim, demand, damage, debt and liability (including payment of attorneys’ fees and costs actually incurred whether or not litigation is commenced) based on or arising out of any such assignment or transfer. The provisions of this section shall survive the date hereof. Nothing herein is or should be construed to be a release of claims against Agri-Energy or Gevo or a satisfaction of any indebtedness.
