                                  Application for Earth Station Special Temporary Authority

              JUSTIFICATION FOR SPECIAL TEMPORARY AUTHORITY

PetroCom License Corporation (“PetroCom”), pursuant to the provisions of Section 25.120 of
the rules and regulations of the Federal Communications Commission (“FCC” or “Commission”)
hereby requests that the FCC grant it special temporary authority (“STA”), for a period of thirty
(30) days, beginning on November 23, 2007, to operate the facilities associated with the satellite
earth station (the “Station”) described in the attached technical description, for testing purposes
only. PetroCom will ultimately operate the Station from the Tahiti oil production platform (the
“Platform”) in the Gulf of Mexico (the “Gulf”) owned by Chevron. The Station will allow
PetroCom to provide service to Chevron. The Station will permit Chevron to communicate from
the Platform to Chevron personnel on shore. It is anticipated that the Station will be shipped to
the Platform within sixty (60) days of grant of STA. PetroCom has received authority to operate
the Station on a permanent basis from the Platform.1/ The FCC previously issued STA to
PetroCom covering the interim operation of this station for testing purposes, but testing is not yet
complete and the Station is not yet ready to be shipped to the Platform.2/

As the FCC has recognized by granting PetroCom STA for testing purposes under similar
conditions, prior to shipping the Station to the Platform and deploying the Station on the
Platform, it is necessary for PetroCom to test the Station at a shipyard in Ingleside, Texas.3/ By
testing the Station before it is deployed in the Gulf, PetroCom will be able to ensure its proper
functioning prior to shipment. Once the Station is shipped to the Platform it will be the principal
source of communications from the Platform. Because the Station will be the primary means of
communications on the Platform, testing after the installation of the Station poses a risk to the
safety and health of personnel onboard as well as to the environment, in the event of an incident
requiring intervention. With testing verified at the shipyard in Ingleside, communications will be
available immediately once the Station is installed.

Accordingly, testing of the Station at the shipyard location is necessary before the Station is
transported to the Platform in the Gulf. STA under these conditions is contemplated by Section

25.120(a) of the FCC’s rules, which states that STA may be requested for “circumstances
requiring…temporary use of facilities.” It would be inefficient for the FCC to process an
application for permanent authorization for the Station at the shipyard facility, because of the
limited duration at which the Station will be located there.

Accordingly, the FCC is requested to issue STA to PetroCom, effective November 23, 2007, for
a period of thirty (30) days, so that it may test the Station on land before it is deployed to the
Platform in the Gulf. If there are any questions regarding this STA request, the FCC is asked to
contact communications counsel for PetroCom, Russell H. Fox of Mintz, Levin, Cohn, Ferris,

                                  Application for Earth Station Special Temporary Authority


                                      Request for Waiver

PetroCom License Corporation (“PetroCom”) hereby requests that the Federal Communications
Commission (“FCC” or “Commission”) waive the provisions of Section 25.209 to permit it to
operate an earth station antenna in the 4/6 GHz Band (the “C Band”) that does not comply with
the antenna gain limitations specified in the FCC’s rules. This waiver request is submitted in
support of PetroCom’s request for special temporary authority (“STA”) to test a satellite earth
station (the “Station”) at a location other than where it will be permanently installed. PetroCom
has obtained permanent authorization for the Station, which included a separate request for
waiver of the rules in connection with that application.1/ Attached to this wavier request are the
following exhibits:

       Exhibit A - Frequency Coordination for Testing
       Exhibit B - Radiation Hazard Study
       Exhibit C - Schedule B, Technical and Operational Description of Earth Station During
       Testing
       Exhibit D - Electrical Test Report for SeaTel 2.4 m Antenna
       Exhibit E - Data Tables
       Exhibit F - Affidavits from Adjacent Satellite Operators

PetroCom attests to the fact that, as demonstrated by the attached Radiation Hazard Report
(Exhibit B), the safe limits for non-ionizing radiation (1m/W/cm²) will not be exceeded.

Despite the fact that the main beam of the proposed earth station antenna does not conform to the
provisions of Section 25.209(a) and (b), the FCC should grant the requested waiver and STA
because PetroCom will not cause unacceptable levels of interference under conditions of uniform
2 degree orbital spacings. The antenna pattern of the Station exceeds the gain specifications of
Section 25.209 for the sidelobe envelope in the ±1.0° to 1.9° region by a maximum of 9.0 dB,
at 6 GHz. Outside the main beam, the antenna meets the requirements of Section 25.209 of the
FCC’s rules.

However, the effects of non-compliance with the antenna gain requirements are ameliorated by
the reduction in power of the transmit antenna. The provisions of Section 25.212 of the FCC’s
rules specify that the maximum RF power density normally licensed for smaller diameter
antennas, utilizing C-band data traffic, is -2.7 dBW/4 kHz. The Station is proposed to operate
with an RF transmit power density of –34.96 dBW/4 kHz. A comparison of the FCC’s
maximum authorized RF transmit power density (-2.7 dBW/4 kHz) and the actual transmit
power density of the proposed earth station (-34.96 dBW/4 kHz), indicates that the applied-for
transmit power density is 32.76 dBW lower than the specified power restrictions. When the

(granted July 31, 2007).


antenna pattern envelopes are considered, the applied-for transmit power density is still 23.76
dBW less than the maximum RF power density normally licensed by the FCC.

To support Petrocom’s claim that the operation it proposes will not cause adjacent satellites
exposure to greater EIRP density from PetroCom’s facilities than those adjacent satellites would
experience from an antenna conforming to the gain patterns of Section 25.209(a) and operating
at the EIRP density limits specified in Section 25.212(c), Petrocom submits an Electrical Test
Report prepared for the antenna manufacturer showing the gain patterns of the antenna. To
supplement this claim Petrocom is also submitting a data table showing how the proposed
operation meets the Commission’s off-axis criteria at various elevation angles.

This reduced RF transmit power will result in acceptable performance for the antenna with
respect to adjacent satellite interference. PetroCom will operate with the AMC-3 satellite (87
degrees W.L.). PetroCom has obtained consent to the use of these non-conforming antennas
from all affected parties. Affidavits from PanAmSat and Loral attesting that they are aware and
acknowledge Petrocom’s proposed operation in the C Band and that they do not object to that
operation are attached hereto. In any case, if the use of this antenna should cause interference
into other systems, PetroCom will terminate transmissions immediately upon notice from the
affected parties.

Finally, PetroCom notes that previous licenses and STAs have been granted to it by the FCC for
this size antenna, including for this Station.2/ Accordingly, grant of the requested STA and the
forthcoming underlying application will be consistent with past Commission practice.

Should there be any questions regarding this waiver request, the FCC is asked to contact
communications counsel for PetroCom, Russell H. Fox of Mintz, Levin, Cohn, Ferris, Glovsky
and Popeo, P.C., 202-434-7483, rfox@mintz.com.

      Analysis of Non-Ionizing Radiation for a 2.4-Meter Earth
                          Station System
This report analyzes the non-ionizing radiation levels for a 2.4-meter earth station system. The
analysis and calculations performed in this report comply with the methods described in the FCC
Office of Engineering and Technology Bulletin, No. 65 first published in 1985 and revised in 1997
in Edition 97-01. The radiation safety limits used in the analysis are in conformance with the FCC
R&O 96-326. Bulletin No. 65 and the FCC R&O specifies that there are two separate tiers of
exposure limits that are dependant on the situation in which the exposure takes place and/or the
status of the individuals who are subject to the exposure. The Maximum Permissible Exposure
(MPE) limits for persons in a General Population/Uncontrolled environment are shown in Table 1.
The General Population/Uncontrolled MPE is a function of transmit frequency and is for an
exposure period of thirty minutes or less. The MPE limits for persons in an
Occupational/Controlled environment are shown in Table 2. The Occupational MPE is a function of
transmit frequency and is for an exposure period of six minutes or less. The purpose of the
analysis described in this report is to determine the power flux density levels of the earth station in
the far-field, near-field, transition region, between the subreflector or feed and main reflector
surface, at the main reflector surface, and between the antenna edge and the ground and to
compare these levels to the specified MPEs.

1.      Far Field Distance Calculation

The distance to the beginning of the far field can be determined from the following equation:

     Distance to the Far Field Region                       Rff = 0.60 D2 / λ                   (1)
                                                                = 71.4 m

The maximum main beam power density in the far field can be determined from the following
equation:

     On-Axis Power Density in the Far Field                 Sff = G P / (4 π Rff 2)             (2)
                                                                = 2.598 W/m2
                                                                = 0.260 mW/cm2

2.      Near Field Calculation

Power flux density is considered to be at a maximum value throughout the entire length of the
defined Near Field region. The region is contained within a cylindrical volume having the same
diameter as the antenna. Past the boundary of the Near Field region, the power density from the
antenna decreases linearly with respect to increasing distance.

The distance to the end of the Near Field can be determined from the following equation:

     Extent of the Near Field                               Rnf = D2 / (4 λ)                    (3)
                                                                = 29.7 m

The maximum power density in the Near Field can be determined from the following equation:

     Near Field Power Density                               Snf = 16.0 η P / (π D2)             (4)
                                                                = 6.065 W/m2
                                                                = 0.607 mW/cm2

3.      Transition Region Calculation

The Transition region is located between the Near and Far Field regions. The power density
begins to decrease linearly with increasing distance in the Transition region. While the power
density decreases inversely with distance in the Transition region, the power density decreases
inversely with the square of the distance in the Far Field region. The maximum power density in
the Transition region will not exceed that calculated for the Near Field region. The power density
calculated in Section 1 is the highest power density the antenna can produce in any of the regions
away from the antenna. The power density at a distance Rt can be determined from the following
equation:

     Transition Region Power Density                        St = Snf Rnf / Rt                   (5)
                                                               = 0.607 mW/cm2

4.      Region between the Feed Assembly and the Antenna Reflector

Transmissions from the feed assembly are directed toward the antenna reflector surface, and are
confined within a conical shape defined by the type of feed assembly. The most common feed
assemblies are waveguide flanges, horns or subreflectors. The energy between the feed assembly
and reflector surface can be calculated by determining the power density at the feed assembly
surface. This can be determined from the following equation:

     Power Density at the Feed Flange                     Sfa = 4000 P / Afa                (6)
                                                              = 685.852 mW/cm2

5.      Main Reflector Region

The power density in the main reflector is determined in the same manner as the power density at
the feed assembly. The area is now the area of the reflector aperture and can be determined from
the following equation:

     Power Density at the Reflector Surface           Ssurface = 4 P / Asurface             (7)
                                                               = 9.947 W/m2
                                                               = 0.995 mW/cm2


6.      Region between the Reflector and the Ground

Assuming uniform illumination of the reflector surface, the power density between the antenna and
the ground can be determined from the following equation:

     Power Density between Reflector and Ground           Sg = P / Asurface                 (8)
                                                             = 2.487 W/m2
                                                             = 0.249 mW/cm2

It is the applicant's responsibility to ensure that the public and operational personnel are not
exposed to harmful levels of radiation.



8.     Conclusions

Based on the above analysis it is concluded that harmful levels of radiation will not exist in regions
normally occupied by the public or the earth station's operating personnel. The transmitter will be
turned off during antenna maintenance so that the FCC MPE of 5.0 mW/cm2 will be complied with
for those regions with close proximity to the reflector that exceed acceptable levels.

  INTRODUCTION:
          This report summarizes the electrical testing performed on a          $.4 meter modified offéet
  antenna. The testing has been completed for Sea—Tel, Incorporated per pufchase order # 30100.

  DBESCRIPTION OF TEST ARTICLE:
         The antenna tested is comprised of a reflector a feed and a spar set
          The reflector was designed for efficient use of a specified l;rxisting Sea—Tel radome
  configuration. Refer to Seavey Engineering drawing 9814—08 for reflecto Adetails. The manufactured
  reflector was supplied to eavey Engineering by Sea—Tel.
          The feed is a dual eiree   polarized transmait and receive C—bmiIssembly. Refer to Seavey
 Engineering drawing 9814—800 for feed details.
       There are three spars to position the feed correctly in the r            ector.   Refer to Seavey
 Engmeermg drawing 9814—550 for spar details                         |

 TESTS PERFORMED:
         The antenna has undergone testing for radiation patterns, gain and i ross polarization. The
 radiation patterns were taken on Seavey Engineering‘s 850—foot antenna tg t range. The antenna
 under test was mounted to a three—axis positioner on top of a 30—foot test jfower. The transmitting
 source antenna was a 7—foot solid parabolic reflector. The data has been r Scorded on a standard
 Scientific—Atlanta chart recorder.
        Gain data was taken using the substitution method. The gain standbrd for the receive band is
 a Narda #643 horn. The gain standard for the transmit band is a Narda #642 horn.

To Whom It May Concern:

This letter certifies that SES Americom, Inc. ("SES Americom") is aware that PetroCom License
Corporation, ("PetroCom®"), is filing to operate on the SES Americom satellite AMC—3 at 87°
W.L. licensed by the Federal Communications Commission ("FCC"), using C—band
transwit/receive antennas that are not strictly compliant with the FCC rules for off—axis sidelobe
gain."

The C—band terminal uses the Prodelin antenna with an aperture of 2.4 meters or the SeaTel
antenna with an aperture of 2.4 meters. SES—Americom understands that these antennas are
installed on oil platforms at fixed locations and generally exhibit non—compliance performance in
the region from 1.0 to1.6 degrees off axis from the maximum gain. The antennas comply at 1.6
degrees and beyond with the requirements of Section 25.209 of the FCC‘s rules.

In order to prevent potential unacceptable interference from antenna misalignment, Petrocom
will align the 2.4 meter antennas to less than or equal to 0.5 degrees offset in the azimuth
direction of the intended satellite. In addition, the uplink power density for the antennas
operating on the AMC—3 satellite at 87° W.L. will not exceed —12.0 dBW/4 kHz into the antenna
flange.

SES Americom acknowledges that the use of the Prodelin 2.4 meter antenna and the SeaTel 2.4
meter antenna by PetroCom, installed and operated in accordance with the above conditions,
should not cause unacceptable interference into adjacent satellites in accordance with FCC‘s 2—
degree spacing policy and that Petrocom will accept interference from adjacent satellites to the
degree to which harmful interference would not be expected to be caused to an earth station
employing an antenna conforming to the reference patterns defined in Section 25.209 of FCC
rules.   If the use of this antenna should cause interference into other systems, Petrocom has
agreed that it will terminate transmission immediately upon notice from the affected parties.
