(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
       been increased by 3,450,000 to 16,766,377 and 16,996,573 for the three
       months ended March 31, 1997 and 1996, respectively, and by 3,450,000 to
       16,747,042 and 16,905,943 for the nine months ended March 31, 1997 and
       1996 respectively.

       As a result of reduced interest expense following conversion, the
       increase to net income (or decrease to net loss) would have been $647,000
       for the three months ended March 31, 1997 and 1996, respectively and
       $1,941,000 for the nine months ended March 31, 1997 and 1996,
       respectively. These adjustments would have resulted in fully diluted
       earnings/(loss) per share of $0.10 and $(0.82) for the three months ended
       March 31, 1997 and 1996 respectively and $(0.31) and $(0.54) for the nine
       months ended March 31, 1997 and 1996 respectively.
