A reconciliation of the number of weighted shares used to compute basic and diluted net earnings per share for the three and six months ended June 30, 2012 and 2011 are illustrated below:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2012		2011		2012		2011
Weighted average common shares outstanding for basic EPS	33,525,003		30,462,593		32,454,850		30,419,040
Effect of dilutive securities: employee stock options		353,242		447,537		385,229		440,716
Adjusted weighted average common shares outstanding for diluted EPS		33,878,245		30,910,130		32,840,079		30,859,756

Weighted options to purchase a total of 404,526 and 92,049 shares of the Company's common stock for the three months ended June 30, 2012 and 2011, respectively, and 401,790 and 79,677 shares of the Company's common stock for the six months ended June 30, 2012 and 2011, respectively, were excluded from the calculations of fully diluted earnings per share, in each case because the effect on fully diluted earnings per share for the period was antidilutive.
