  (1)  Weighted average share and dollar amounts, except per 
       share amounts, are stated in thousands

  (2)  Shares issued from assumed exercise of options and 
       warrants include the number of incremental shares 
       which result from applying the "treasury stock method" 
       for options and warrants, APB Opinion No. 15, paragraph
       36.  The options and warrants are antidilutive in 1996
       and are not included in the calculation.

  (3)  This calculation is submitted in accordance with 
       17 CFR 229.601(b)(11) although not required by APB 
       Opinion No. 15 because it results in dilution of less 
       than 3%.
