YEAR 2000. Agilent Technologies warrants that each Agilent Technologies
hardware, software, and firmware product on Agilent Technologies’
Corporate Price List (dated July 1, 1998 or later) delivered under the
product’s contract of sale will be able to accurately process date data
(including, but not limited to, calculating, comparing, and sequencing) from,

with the product documentation provided that all other products (that is,
hardware, software, firmware) used in combination with such Agilent
Technologies product(s) properly exchange date data with it. If the
agreement requires that specific Agilent Technologies products must
