The number of shares have been adjusted for the Company's 3 for 2 stock split in
February 2003.

The number of anti-dilutive weighted average shares that have been excluded in
the computation of diluted earnings per share for the year ended June 30, 2004
was 178,500. These shares have been excluded because the options' exercise price
was greater than the average market price of the common stock. There were no
anti-dilutive weighted average shares excluded in the computation for 2003 and
2002.

                                                                              94
