(A) The treasury stock method was used to calculate the common stock equivalent
    number of shares from options and warrants.

(B) Adjustments for interest and amortization, option and warrant equivalent
    shares and additional shares from the conversion of debentures issued in
    1989 are not included in the calculation for the quarter ended June 30, 1995
    as their effect would be antidilutive.
