The unaudited earnings per share for all periods presented were computed based
on the weighted average number of shares of common stock outstanding and common
stock equivalents. While the market price of common stock as of June 30, 1997
was above the average for the six months ended June 30, 1997, the dilutive
impact was immaterial.
