*Because the Company reported net losses for the three and nine months ended
September 30, 2001 and 2000, respectively, the calculation of net loss per share
- - diluted excludes potential common shares from stock options, as they are
anti-dilutive and would result in a reduction of loss per share. If the Company
had reported net income for the three and nine months ended September 30, 2001,
there would have been 75,711 and 73,990 additional shares in the calculation of
net income per share - diluted. If the Company had reported net income for the
three and nine months ended September 30, 2000, there would have been 13,233 and
113,205 additional shares in the calculation of net income per share - diluted.
