     which the Company shall cause FIFO Net Income (Loss) to be greater than
     ($22,500,000) for such period and (ii) the short-term measurement periods

     September 1, 1996, October 1, 1996, November 1, 1996 and December 1, 1996,
     for which the Company shall cause FIFO Net Income (Loss) to be greater than

     that is material to its or any of its Subsidiaries' business and operations
     will not be Year 2000 compliant on a timely basis, except to the extent
     that such failure would not present a material probability of causing a
     Material Adverse Change.
