     (1)  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 1995 and are not included in the calculation.

     (2)  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%.

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