(1)   The interest component of rent expense has been estimated by taking the
      difference between the gross rent expense and net present value of rent
      expense using a weighted-average cost of capital of approximately 13% for
      the years ended December 31, 1995 through December 31, 1998. The weighted-
      average cost of capital for the year ended December 31, 1999 and for the
      nine months ended September 30, 1999 and 2000 approximated 9%. The cost of
      capital used to calculate the interest component of rent expense is
      representative of the Company's outstanding borrowings during each
      respective period.
