                              AMENDED SCHEDULE - A

                             TECHNICAL SPECIFICATION


         Initial frequency contemplated as being 1.8 gHz;

Equipment Provided:

         The Central Office Terminal (COT) and Radio Distribution Unit (RDU)
equipment connect the TrueLink(TM) Radio Carrier Station (RCS) to the phone
network switch. The RCSs are the "base stations". The Fixed Subscriber Units
(FSUs) are installed at the customers premises. The Local Craft Terminals (LCTs)
and Field Measurement Units (FMUs) are used for installation and system control.

         The site, when completely built-out will consist of 1 RDU, 1 COT, 1
LCT, 1 RCS, 50 FSUs and 1 FMU.

Time Frame:

         The TrueLink(TM) equipment, and more importantly the system's
operation, will be installed and made operational on a phased schedule. During
this period service may be interrupted as RDU, COT and RCS capacity is increased
and/or modified. The final schedule will depend on material availability,
availability of installation personnel and system performance. Phases shall not
be initiated until the installation and verification of system performance is
verified for the previous stage.

         Detailed scheduling will be determined prior to installation by mutual
agreement. Installation of the TrueLink(TM) equipment will not commence until
the required licenses and frequencies are procured pursuant to Section 9.0 of
this Agreement.

Provided Services/Capabilities:

         32 Kbit/s ADPCM - Voice call - with dial and DTMF capability.

         64 Kbit/s PCM channel for up to 14.4 Kbit/s FAX and 28.8 Kbit/s modem
data.

         All equipment is supplied for indoor installation and use only.

         Network interface will be 2 wire analog provided by conversion of V5.1
interface with COT.


                                        3

         RCS Antenna height will be the maximum that WWW can provide. The RCS
antenna will be omni-directional.

         The FSUS antenna height shall not extend beyond the roof line, except
where an existing TV antenna mast can be used, unless permission of the owner is
granted. There may be situations where a "line of sight" antenna installation
aimed toward the base station will not be possible without extending above the
roof line.

         The FSUS will require 120 VAC, 60 Hz at a maximum of 30 watts. IDC will
assume no responsibility for installation or upgrading of customer's electrical
service or outlets.

Miscellaneous:

         Subsequent to Beta-Site installation, the capability for POTS (as that
term is used in the industry), and thereafter ISDN data capability, may be
evaluated upon terms and conditions as agreed upon at that time between the
parties.
