A reconciliation of the number of weighted shares used to compute basic and diluted net earnings per share for 2012, 2011 and 2010, are illustrated below:

	2012		2011		2010
Weighted average common shares outstanding for basic EPS		33,015,323		30,445,772		29,978,034
Effect of dilutive securities: employee stock options		346,395		396,741		328,328
Adjusted weighted average common shares outstanding for diluted EPS		33,361,718		30,842,513		30,306,362

Options to purchase a total of 440,786, 154,449 and 125,543 shares of the Company's common stock were excluded from the calculation of fully diluted earnings per share for 2012, 2011 and 2010, respectively, because their effect on fully diluted earnings per share for the period were antidilutive.
