        With this application, Maritime Telecommunications Network, Inc. (“MTN”) requests
special temporary authority for 30 days to operate one temporary fixed Ku-band 1.0 meter earth
station. The authority requested herein will permit communications in areas affected by
Hurricane Katrina.

           The technical and operational specifications for the earth station requested herein
follows:

       Area of Operation:               Areas Affected by Hurricane Katrina
