ViaSat, Inc.
Request for Special Temporary Authority

                                         Attachment A

                  Description of Request for Special Temporary Authority

               ViaSat, Inc. (“ViaSat”) hereby requests special temporary authority (“STA”), to
operate a 7.3 m meter Model VA-73-KA transmit/receive antenna operating in the Ka-band in
Rapid City, South Dakota for purposes of service testing and demonstration. ViaSat requests
authority commencing on April 11, 2011 for a period of 180 days.

               ViaSat intends to use this antenna as a traffic gateway for its VIASAT-1 satellite,
which is scheduled for launch during the summer of 2011. ViaSat requests this STA to allow
testing and demonstration of the SurfBeam® 2 ground station equipment prior to the launch of
VIASAT-1. ViaSat owns and manages capacity on the ANIK-F2 spacecraft which it will use for
this purpose. The public interest will be served by the grant of this STA because it will allow
ViaSat to conclude testing of the antenna to ensure the integrity of the ground network that will
support the operation of services on VIASAT-1 later this year.

               This antenna complies with the antenna performance specifications in Section
25.209 and, it will comply with the off-axis EIRP performance levels set forth in Section 25.138
of the Commission’s rules.

               This STA requests the addition of the frequency range 28.35 – 28.6 GHz to those
already authorized under STA 0211-EX-ST-2011 (WE9XVP ). Other than the addition of these
new frequencies, all other technical information remains the same.
