                                   EXHIBIT B-3

                        Mobile IP Internet Access Pricing

                       Platinum and Palm Platinum Pricing

Verizon Wireless' Commitment Plans require a minimum number of units in service
on the network during specific times. Please see the commitment schedules below
for the associated commitment time frames. Verizon Wireless' Mobile IP Platinum
Commitment plan has a minimum number of units commitment of [**] and its Mobile
IP Palm Platinum Plan has a minimum number of units commitment of [**]. However,
for the purposes of this Amendment, Customer must maintain a minimum number of
[**] NEIs across the rate plans shown in this Exhibit B-3. In the event that
Customer does not activate or falls below the minimum number of units, Customer
will be invoiced as if the total number of units associated with their
Commitment Plan were active. Verizon Wireless will invoice Customer the
difference between the units in service and the commitment level for that month,
multiplied by the monthly access fee of $[**]. At the end of the first year of
the Extended Term of this Agreement, Customer must maintain [**] units in
service during a given month. If such minimum is not maintained, Customer will
be charged $[**] monthly access fee for those units that represent the
shortfall.

The volume commitments shown below are in addition to existing commitments
contained in Contract ####-##-####, dated May 13,1997 and its subsequent
Amendments 1 and 2. NEIs active on the $[**] price plan contained in Contract #
###-##-#### and its subsequent Amendments 1 and 2, may convert to the $[**] rate
plan shown in this Exhibit B-3, but shall not count towards Customer's [**] NEI
minimum commitment.

All price plans are only available for Customer for the provision to its
Authorized Users as part of the mobile data communications system which offers
bundled Customer content through standard browser-based Internet applications
only, intended for use with Palm OS handhelds, Microsoft Pocket PC based
handhelds, and Microsoft Windows based notepads and laptops. No telemetry, AVL,
or public safety applications will be available on these plans. Pursuant to the
terms of this Agreement, Verizon Wireless reserves the right to investigate the
usage of any NEI and reserves the right to suspend NEIs that are being used
fraudulently.

(insert) Each new IP activated is for a one year contract. If the individual IP
is not in service for twelve months, an early termination fee of $[**]per will
be applied.
