(1)  Convertible debentures have not been assumed converted for the fully
     diluted earnings per share as the effect would be anti-dilutive. Had the
     convertible debentures been included, the number of shares would have
     increased by 3,450,000 for the three months ended September 30, 1996 and
     1997 respectively.

     As a result of reduced interest expense following conversion, the increase
     to net income would have been $647,000 in 1996 and 1997. These adjustments
     would have resulted in a fully diluted income (loss) per share of $0.05 and
     $0.18 for the three months ended September 30, 1996 and 1997, respectively.
