         and LICENSEE agree that neither the Patent License Agreement nor this
         Amendment may be amended, modified or terminated without the prior
         written consent of Ponte Nossa Acquisition Corp.; provided, however,
         that this consent requirement shall terminate if the transaction
         contemplated by the Agreement and Plan of Merger have not been
