              *This calculation is submitted in accordance with
              Securities Exchange Act of 1934 Release No. 9083,
              although not required by footnote 8, paragraph 40,
              of APB No. 15 because it results in anti-dilution. 
              In addition, common equivalent shares are not
              considered in the computation of earnings per
              common share for March 31, 1997, as the impact
              would be antidilutive.
