(a)       This  calculation is submitted in accordance  with Regulation S-K item
          601  (b)(11)  although  it is  contrary  to  paragraph  13 of SFAS 128
          because it produces an anti-dilutive result. Diluted net income (loss)
          per share  computed in accordance  with SFAS 128 was the same as basic
          earnings per share.
