(1) For leases where the interest factor can be specifically identified, the
    actual interest factor was used. For all other leases, the interest factor
    is estimated at one-third of total rent expense for the applicable period
    which management believes represents a reasonable approximation of the
    interest factor.

(2) The Company's earnings for the years ended December 31, 1996 and 1997 were 
    inadequate to cover fixed charges by $48,488 and $74,757, respectively.
