Had the convertible debentures been included, the number of shares would have increased by 3,450,000 in 1995, 1996 and 1997. As a result of reduced interest expense following conversion, the increase to net income (or decrease to net loss) would have been $2,588,000 in 1995, 1996 and 1997. These adjustments would have resulted in a fully diluted income (loss) per share of $0.47, $(0.46) and $(0.16) in 1995, 1996 and 1997, respectively.
