                             Amended and Restated Exhibit A

I.     DESCRIPTION OF STA REQUEST

        ISAT US Inc. (“ISAT US”) hereby requests special temporary authority (“STA”) to
operate a 3.5 meter earth station located at Lino Lakes, Minnesota to facilitate over-the-air
site acceptance testing (OSAT) and end-to-end testing of the 30.0-31.0 GHz and 20.2-21.2
GHz payload on the Inmarsat Global Xpress Ka-band network, using the Inmarsat 5 F2
(I5F2) satellite located at 55º W.L. The earth station antenna type is the ASC Signal 3.5 Ka-
band Earth Station antenna (“Antenna”), a summary of which is attached as Annex A. All
operations would be at a fixed location at the Lino Lakes site, which site has been previously
authorized for use with the I5 F2 satellite. 1 This testing would be done in consultation with
an element of the U.S. armed forces.

        As explained in the application for the Lino Lakes and I5F2 U.S. market access
authority, in addition to the “conventional” part of the Ka band, the I5F2 spacecraft also
includes the capability of communicating in certain beams in the 30.0-31.0 GHz and 20.2-
21.2 GHz bands, which are not allocated for commercial service in the United States and for
which U.S. market access authority has not been sought. Operation of this part of the
spacecraft will occur under the authority of Norway, pursuant to ITU filings submitted by the
Norwegian Administration. 2 Inmarsat acknowledges that it or one of its authorized military
customers would need to obtain separate authority prior to initiating U.S. service in those
bands. The I5F2 satellite has been fully coordinated with the relevant parties in the United
States Executive Branch for the 55º W.L. orbital location, including for the frequency bands
limited to military use (i.e., 30.0-31.0/20.2-21.2 GHz) under the U.S. Table of Frequency
Allocations. This additional terminal will be used for the purposes of testing the capabilities
of the spacecraft only in the 20.2-21.2 GHz and 30.0-31.0 GHz band segments and is not
intended for regular or permanent use in those bands.

        ISAT US will be responsible for the operation of the Antenna during the tests. The
operations will be closely monitored by the Inmarsat Network Operations Center (NOC) and
various engineering teams associated with the OSAT and testing campaign to ensure
compliance with the requested testing authority. It is expected that the Antenna will be used
starting August 14, 2015 for up to 30 days.

       The Norwegian Administration has submitted on behalf of Inmarsat an ITU filing
       under the filing name SE-KA-55W, as published by the ITU in IFIC 2717
       (CR/C/3054) on 17 April 2012 (date of receipt November 11, 2011).


II.    ISAT US SEEKS AUTHORITY TO TEST THE ANTENNA AT 20.2-21.2 GHZ
       AND 30.0-31.0 GHZ AND, TO THE EXTENT IT APPLIES, GOOD CAUSE
       EXISTS FOR A WAIVER OF SECTION 2.106

         ISAT US seeks authority to test the Antenna on the following frequency bands: 30.0-
31.0 GHz (uplink) and 20.2-21.2 GHz (downlink). ISAT US requests this authority on a non-
interference and non-protected basis. ISAT US requests a waiver of the U.S. Table of
Frequency Allocations, as necessary, to allow the proposed STA operations in the 30.0-31.0
GHZ and 20.2-20.2 GHz frequencies. 3 Grant of a waiver would serve the public interest
because it would allow end-to-end network testing of the portion of the I5F2 spacecraft that
uses these band segments and associated Global Xpress network components with the OSAT,
facilitating the deployment of satellite broadband services in these band segments to
approved military users. As discussed below, grant of the requested waiver would not
undermine the policy objective of the rule, as regular or permanent authority for this Antenna
is not being sought and the primary operators in these bands under the U.S. Table would be
protected from harmful interference.

       ISAT US seeks authorization only for limited testing of the 30.0-31.0 GHz and 20.2-
21.2 GHz capabilities of I5F2. As noted above, the Commission granted market access for
I5F2’s other communications capabilities, and, in that context, all of the information required
by Sections 25.137 and 25.114 was provided. Below, ISAT US provides the following
additional information that it is relevant to the proposed OSAT and end-to-end testing:

Technical Parameters

Station Class: FXO

EARTH-to-SPACE:
Transmit Frequencies: 30.0-31.0 GHz

       See 47 C.F.R. § 2.106, footnote G117 (in the bands 7.25-7.75 GHz, 7.9-8.4 GHz,
       17.375-17.475 GHz, 17.6-21.2 GHz, 30-31 GHz, 33-36 GHz, 39.5-41 GHz, 43.5-45.5
       GHz, and 50.4-51.4 GHz, the Federal fixed-satellite and mobile-satellite services are
       limited to military systems).


                                               2


RF Modulation: 64QAM
Azimuth Range: Fixed Pointed to I5F2 at 55º W.L. – Az = 132.2 degrees

The maximum uplink off-axis EIRP density of any single I5F2 carrier in the direction of the
geostationary orbital slot of 52.5º W.L. will not exceed -30 dBW/Hz, and the maximum
downlink EIRP density of any single I5F2 carrier will not exceed -15.9 dBW/Hz.

Beacon Signal: The signal beacon on I5F2 will operate at a frequency centered at 20.68 GHz
with a maximum EIRP of 30 dBW, and the 20.7 GHz beacon will be muted.

Duration of Communications: approximately 30 days


Space Station Coordination

        The coordination of communications for the use of the additional frequencies (30.0-
31.0 GHz/20.2-21.2 GHz) with the I5F2 spacecraft at the 55º W.L. orbital location with
existing spacecraft operators, including the U.S. Government, during the proposed testing is
the responsibility of Inmarsat and ISAT US. ISAT US has undertaken coordination of
communications for the support of the OSAT and end-to-end testing of I5F2 with other
spacecraft operators that may be potentially affected during testing.

        All the preparatory activities and contacts for such coordination have been made and
all issues have been satisfactorily resolved. ISAT US also has undertaken to review the need
for coordination based on any changed circumstances that may occur. In accordance
with normal industry practices, communications with other operators will be kept open in the
period leading to and throughout the testing activities, to ensure that the testing will be
conducted on a non-interference basis. Grant of the proposed STA on a non-interference,
non-protected basis would not prejudice any future operations in this band.

                               *      *       *      *       *

        Grant of the requested STA will serve the public interest, convenience and necessity
because it will enable ISAT US to conduct essential network testing and the I5F2 spacecraft,
within technical parameters consistent with the parameters described herein using the
identified Antenna, without creating any risk of harmful interference. ISAT US respectfully
requests that the Commission grant STA beginning August 14, 2015 for a period of 30 days.
