Had the convertible debentures been included, the number of shares would have been increased by 3,450,000 to 16,815,169 and 16,972,113 for the three months ended December 31, 1996 and 1995, respectively, and by 3,450,000 to 16,756,262 and 16,965,696 for the six months ended December 31, 1996 and 1995 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 December 31, 1996 and 1995, respectively. These adjustments would have resulted in fully diluted earnings/(loss) per share of $(0.46) and $0.11 for the three months ended December 31, 1996 and 1995 respectively and $(0.41) and $0.12 for the six months ended December 31, 1996 and 1995 respectively. 14
