     racks, patch panels and other equipment.

     radios and therefore, once TeleCorp defines its requirements, TeleCorp may
     hire Lucent's Network Management to integrate the two platforms for an
     additional price.  Both parties recognize that the number of links has
     increased dramatically.  Lucent will only be able to evaluate the cost of
     the additional network management services required after TeleCorp

     the third party.

     products on or about  April 30, 1999.  DMC will, however, provide TeleCorp

     repairs or replacements in the event such repairs or replacements become
