to the  Assets or the  Clinical  Trials  Business  of  whatever  kind or nature,
whether  contingent or absolute,  whether  arising prior to or on or after,  and

specifically  referred to in this Agreement (such  liabilities and  obligations,
except  as set  forth  in  paragraphs  1.4 and 1.7  hereof,  being  collectively

     as more  fully set  forth on a  Disclosure  Schedule  attached  hereto  and
     incorporated herein by reference.

     (iii) Assurance.  Seller warrants and represents that Buyer will not at any
     time  suffer any  liability  in respect of the  foregoing  liabilities  not
