2.     Conditions of Use

The systems are being considered by Globaltron and its telecommunications
partner companies in Colombia. In order for the systems to be used in other
countries, it will be necessary to include localization services to make them
adequate for the realities of those countries, which are not included in this
business proposal. Furthermore, any and every investment in a computational
platform that might be necessary for this purpose will be the sole
responsibility of Globaltron.


These systems are limited to 40,000 subscribers, and the use of the SAGRE
system is limited to 10 engineering users.

There are different forms of operations systems use and access control for local
telephone service providers and for long distance carriers. In the case or local
telephone service providers, the User Licenses are controlled based on the
subscriber plant, while for the carriers, control is done through the processed
traffic by the billing module using the average monthly CDRs (Call Detail
Records), based on the total annual traffic.

Considering PROMUS' use of the Account Settlement module (CAll), by the carrier
belonging to Globaltron, the total traffic to be considered processed, including
those generated by local telephone service providers that use the system is
limited to 6,000,000 CDRs per month, considering the annual average.




2.1 Conditions for Support and Maintenance

For adequate system maintenance and support to Globaltron, CPqD requires remote
access to the systems via Internet. This is necessary when working with failure
situations, evaluation for corrections and support, or for the updating of
systems.


 2.2   Computational Prerequisites

The systems installation architecture must be a client/server architecture as
described in chapter 9. The link between the server and client stations must
have a minimum speed of 19200 bps for each client station utilizing PROMUS,
SGE, and FLEXFLOW systems, and a minimum speed of 64 kbits/s for the client
stations which utilize the SAGRE system,

For an Increase in use of the system, we will apply a value of US$ 4 per
telephone subscriber and US$ 2 per subscriber of aggregated value service
(Internet clients and unified message services), charged in groups of 100
subscribers when the number of subscribers of the service providers is greater
than 40,000 subscribers, In such cases an increase in processing traffic of 150
CDRs per month will be applied to the traffic limit of 6,000.000 CDRs per month
for each telephone subscriber that exceeds the limit oF 40,000 subscribers.


The number of subscribers must he reported on a monthly basis to CPqD, who
reserves the right to perform periodical auditing in order to verify the amount
of existing subscribers in the systems' database, When the number of subscribers
is greater than the number contracted at the time, the amount related to the
increase will be charged retroactively from the date of the increase.


In order to meet the needs of a start-up company, CPqD is offering, without any
additional costs, the account settlement system, limited to a processing traffic
limit of 6,000,000 CDRs per month, considering the monthly average over a year's
time, including all the carrier and local operator's traffic. For the increase
in the systems' use, there'll be an additional charge of US$ 2 for each: 1000
CDRs processed during the month, exceeding the limit of contracted CURs, The
average, number of CDRs processed during the month must be reported every three
months to CPqD, who reserves the right to perform periodical auditing to verify
this information.


All increases in traffic (CDRs) and in the subscriber base will imply a
correction in the license value.
