Supplemental information:

The difference between average common shares outstanding to calculate basic and assuming full dilution is due to options outstanding under the 1996 Stock Option/Stock Issuance Plan and restricted stock issued under the 2007 Stock Incentive Plan.

The calculation of diluted earnings per share for 2010 excluded from the denominator zero options and 4,000 restricted stock awards granted to employees and directors because their effect would have been anti-dilutive. The calculation of diluted earnings per share for 2009 excluded from the denominator 35,000 options and 4,000 restricted stock awards granted to employees and directors because their effect would have been anti-dilutive. The calculation of diluted earnings per share for 2008 excluded from the denominator 111,000 options and zero restricted stock awards granted to employees and directors because their effect would have been anti-dilutive.
