agreed to release Sequana from any liability or claim in connection with the
Lease Dispute so long as Sequana fully performed under the terms of the First

          SETTLEMENT WITH THE DEBTOR.

     EACH OF THE PARTIES HERETO, BEING AWARE OF SUCH CODE SECTION, HEREBY
     EXPRESSLY WAIVES ANY RIGHTS IT MAY HAVE THEREUNDER AS WELL AS UNDER ANY
