(1)  We reported a loss from  continuing  operations  before  provision  for income taxes and minority  interest for the years ended
     December 31, 2000 and December 31, 2001 and we would have needed to generate additional income from operations before provision
     for income  taxes and  minority  interest  of $18,032,  and $8,131,  respectively  to cover our fixed  charges of $154,975  and
     $177,032, respectively.
