*  Calculation of fully diluted loss per share is submitted in accordance with 
Securities Exchange Act of 1934 Release No. 9083, although it is contrary to 
paragraph 40 of APB Opinion No. 15 because it produces an antidilutive result, 
or is not required by footnote 2 to paragraph 14 of APB Opinion No. 15 because 
it results in dilution of less than 3%.
