NOTE 11:                      EARNINGS PER SHARE

As per ASC 260, basic earnings per share are computed by dividing net earnings available to common shareholders (the numerator) by the weighted average number of common shares (the denominator) for the period presented. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued.

Stock options to purchase 403,550 shares of common stock were outstanding and 334,550 were exercisable during the three and six months ended June 30, 2011. Stock options to purchase 442,550 shares were outstanding and 351,775 were exercisable during the three and six months ended June 30, 2010. During the six months ended June 30, 2010, potentially dilutive shares of 63,807 were not included in the computation of diluted earnings per share because their effects would have been antidilutive. These securities may be dilutive to the earnings per share calculation in the future.

The dilutive potential common shares on warrants and options is calculated in accordance with the treasury stock method, which assumes that proceeds from the exercise of all warrants and options are used to repurchase common stock at market value. The amount of shares remaining after the proceeds are exhausted represents the potential dilutive effect of the securities.
