from and as of the date hereof, the Time Sharing Agreement shall be, and hereby
is, amended as set forth below.

 

  1. NEC and User hereby expressly agree that the Schedule A attached hereto

the Time Sharing Agreement. In the event of a conflict between the terms of the
Time Sharing Agreement and this Amendment No. 2, or between the terms of the
Amendment No. 1 and this Amendment No. 2, the provisions of this Amendment No. 2
shall prevail.

 

  5. This Amendment No. 2 may be executed in counterparts, each of which will be
deemed to be an original, but both of which together shall constitute one and
