Note C:  Earnings Per Share (“EPS”)

SFAS No. 128, “Earnings Per Share,” requires earnings per share to be computed and reported as both basic EPS and diluted EPS.  Basic EPS is computed by dividing net earnings by the weighted average number of common shares outstanding for the period.  Diluted EPS is computed by dividing net earnings by the sum of the weighted average number of common shares and dilutive common stock equivalents outstanding during the period.  Dilutive EPS reflects the potential dilution that could occur if outstanding options to issue common stock were exercised into common stock.

For the three and six months ended July 29, 2006, there were approximately 3,857,600 and 3,641,500 shares, respectively, that could potentially dilute basic EPS in the future that were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive in the periods presented.  For the three and six months ended July 30, 2005, there were approximately 2,519,600 and 2,001,700 shares, respectively, that could potentially dilute basic EPS in the future that were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive in the periods presented.

For the three months ended April 29, 2006 and April 30, 2005, there were approximately 3,164,400 and 1,595,400 shares, respectively, that could potentially dilute basic EPS in the future that were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive in the periods presented.

The following is a reconciliation of the number of shares (denominator) used in the basic and diluted EPS computations (shares in thousands):

For the three months ended October 29, 2005 and October 30, 2004, there were approximately 3,464,000 and 1,834,000 shares, and for the nine months ended October 29, 2005 and October 30, 2004, there were approximately 2,768,000 and 1,057,000 shares, that could potentially dilute basic EPS in the future that were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive (option exercise price exceeds average stock price) in the periods presented.
