*  Calculation of fully diluted loss per share for all periods except the 
three months ended June 30, 1994 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%.
