     date-sensitive functions for all dates before and after January 1, 2000

     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
     commencing on August 1, 1997, September 1, 1997, October 1, 1997, November

     for the mid-term measurement periods commencing on August 1, 1996,
     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
     ($35,000,000) for such periods.  As used in this Section 8.24, "mid-term

     any computer application (including those of its suppliers and vendors)
     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.
