     Fully diluted net income per common and common equivalent share is not 
     separately presented because the effects of including common stock 
     equivalents would be anti-dilutive.  Calculations include certain options
     and warrants granted prior to the Company's initial public offering in 
     accordance with Securities and Exchange Commission (SEC) regulations 
     although contrary to Accounting Principles Board (APB) Opinion No. 15 
     because they produce anti-dilutive results.
