*  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%.
