                            MONTHLY OPERATING REPORT
                                  NOVEMBER 1998







The Debtor in Possession is filing an incomplete Monthly Operating Report due to
the lack of complete records. The former officers of PowerTel, USA, Inc. have
not cooperated with the Debtor by providing the necessary information. The Books
and Records are missing. Therefore, it is impossible for the Debtor to file a
complete Monthly Operating Report.
