         c.       For any call that elapses after more than 1 (one) time
                  differentiation, the calculation is to be made based on each
                  of the time differentiation.

         d.       In order to avoid rating differences due to the different time
                  divisions in Indonesia as grouped into WIB, WITA and WIT, the
                  Parties agree to use the incoming call data, the time of which
