A warrant to purchase 227,376 common shares was outstanding at both December 31, 2010 and 2009 as a result of Park's participation in the CPP. Warrants to purchase an aggregate of 71,984 common shares were outstanding at December 31, 2010 as a result of the issuance of common stock and warrants which closed on December 10, 2010. In addition, warrants to purchase an aggregate of 500,000 common shares were outstanding at December 31, 2009 as a result of the issuance of common stock and warrants which closed on October 30, 2009. All warrants issued on October 30, 2009 had been exercised or expired as of December 31, 2010. The common shares represented by the options and the warrants at December 31, 2010 and 2009, totaling a weighted average of 382,445 and 642,405, respectively, were not included in the computation of diluted earnings per common share because the respective exercise prices exceeded the market value of the underlying common shares such that their inclusion would have had an anti-dilutive effect. The warrant to purchase 227,376 common shares is not included in the 382,445 at December 31, 2010, as the dilutive effect of this warrant pertaining to the CPP was 3,043 shares of common stock at December 31, 2010. The exercise price of this warrant is $65.97.
