                                        Information on MLS Sites

        For the Clifton, Texas, Globalstar gateway site, there are four potential MLS sites, i.e., Category
III airports, within the 200 nautical mile coordination distance. The Clifton site is located at 31-48-06
N, 97-36-45 W. The airports are:

                     IAH        Houston – George Bush International Airport,
                                approximately 163 nautical miles from Clifton
                     AUS          Austin – Bergstrom International Airport,
                                    approximately 91 nautical miles away
                     DFW           Dallas/Ft. Worth International Airport,
                                    approximately 71 nautical miles away
                     AFW         Ft. Worth Alliance Field, approximately 68
                                            nautical miles away

Based on a directory used for MLS coordination purposes, and to the best of its knowledge, GUSA
believes that MLS is not active at any of those sites and will not be active during the requested 180-day
STA period.
