                  Statements were prepared in accordance with generally accepted
                  accounting principles applied on a consistent basis throughout
                  the  periods  covered  thereby  (and  except,  in the  case of
                  interim  financial  statements,  subject  to normal  recurring

                  (and except for the  subsequent  adjustment  made in September
                  1996 to reflect the Profit Participation Obligation),  Company

                  condition of Company and which is required to be disclosed on,
                  or reserved against in, a balance sheet. Sellers have received
                  no notice of any fact  which may form a basis for any claim by
