Anti-Dilutive Securities

Certain option shares were not included in the computation of diluted earnings per share for the three-month and six-month periods ended June 30, 2005 and 2004, since inclusion of these option shares would have anti-dilutive effects, as the options’ exercise prices exceeded the respective average market prices of the company’s shares.
