NOTE 8—NET INCOME (LOSS) PER SHARE

Basic net income (loss) per common share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted income (loss) per share is computed using the weighted average number of common shares and common stock equivalents outstanding. For the three months ended June 30, 2011, common stock equivalents totaling 1,004,577 were excluded from the calculation of diluted earnings per share because of a decline in the average market price of the common stock below the exercise price. As a result of the Company's net losses, all common stock equivalents aggregating 1,063,778 for the three months ended June 30, 2010 and 1,180,908 and 1,135,917 for the six months ended June 30, 2011 and 2010, respectively, were excluded from the calculation of diluted loss per share given their anti-dilutive effect.
