Earnings per share amounts were determined using the treasury stock method. 
This method assumes the exercise of all dilutive outstanding options and
warrants and the use of the aggregate proceeds therefrom to acquire the
Company's outstanding common stock.  Net earnings were divided by the weighted
average number of shares outstanding adjusted for the assumed exercise of the
options and warrants outstanding and repurchase of common stock to calculate
per share amounts.
