Net Income / (Loss) Per Common Share

Note B – Net Income / (Loss) Per Common Share

Basic net income / (loss) per common share is calculated by dividing the net income / (loss) by the weighted average number of outstanding common shares during the period. Diluted net income / (loss) per common share includes the weighted average dilutive effect of stock options and warrants. Potential common shares outstanding as of June 30, 2011 and 2010:

	June 30, 2011		June 30, 2010
Warrants		75,000		75,000
Options		3,036,580		3,401,580

The number of securities not included in the diluted net income per common share for the three months ended June 30, 2011 and June 30, 2010 (because the effect would have been anti-dilutive) were 3,028,784 and 3,476,580, respectively. The number of securities not included in the diluted net loss per common share for the six months ended June 30, 2011 and June 30, 2010 (because the effect would have been anti-dilutive) were 3,111,580 and 3,476,580, respectively.
