(1) Common stock equivalents consist of the Company's Preferred Stock, stock
options, warrants and shares subscribed under the Company's employee stock
purchase plan. The computation of dilutive common stock equivalents is based on
the if-converted method for the Preferred Stock and on the treasury stock method
for the other common stock equivalents using the average market price for the
primary earnings per share computations and the higher of average or period
ending market price for the fully diluted earnings per share computations.
