          facility

     .    Software can be accessed through published interfaces

Client agrees to have the hardware and the third party software required for
testing (operating systems, Oracle, WebLogic, IIS) installed by no later than
September 1, 2000. Webb will assist with the AccelX software installation, setup
and testing which can occur within the two weeks following the installation of
the hardware and the third party software. The AccelX software shall be deemed
accepted upon the earlier occurrence of either the successful demonstration of
the above criteria or by September 15, 2000, if the test has not taken place by

indicate acceptance of the AccelX software.
