          and  primarily  from the gross  negligence  or willful  misconduct  of
          entrenet or any other Indemnified Person. The Company also agrees that
          no  Indemnified  Person shall have any liability to the Company for or

     entrenet shall each contribute to amounts paid or payable in respect of the
     Damages for which such  indemnification  is unavailable or  insufficient in

          provided  that in no event  shall  the  amount  to be  contributed  by
          entrenet  exceed  the amount of fees  actually  received  by  entrenet
          hereunder   (excluding   any   amounts   received  by  entrenet  as  a
          reimbursement of expenses).  The Company and entrenet agree to consult
