As a result of reduced interest expense following conversion, the increase to net income (or decrease to net loss) would have been $657,700 for the three months ended September 30, 1996 and 1995, respectively. These adjustments would have resulted in fully diluted earnings per share of $0.05 and $0.01 for the three months ended September 30, 1996 and 1995 respectively. 12
