 * 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.
