The dilutive effect of stock options, stock purchase warrants, and stock
purchase plan rights are calculated using the treasury stock method. Under this
method, these common stock equivalents are assumed to be exercised and proceeds
from the exercise are assumed to be used to repurchase common stock at the
average market price for primary income (loss) per share and the higher of the
end of the period or average market price for fully diluted income (loss) per
share. The dilutive effect of Convertible Preferred Stock is calculated using
the if-converted method.
