SESAAMERICOM An SES GLOBAL Company September 2, 2003 Federal Communications Commission Satellite and Radiocommunications Division International Bureau 445 12"" Street, SW Washington, D.C. 20554 To Whom It May Concern: This letter certifies that SES Americom, Inc. ("SES Americom") is aware that PetroCom License Corporation, ("PetroCom"), is seeking FCC authorization to operate on the SES Americom satellite AMC—2 at 85° degrees W.L. licensed by the Federal Communications Commission ("FCC"), using C—band transmit/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 meter. SES— Americom understands that this antenna generally exhibits non—compliance performance in the region from 1.0° to 1.6° degrees off axis from the maximum gain. The antenna complies 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 meters antenna to less than or equal to 0.5 degrees offset in the azimuth direction of the intended satellite. In addition, PetroCom will reduce the transmitter power density level into the antenna flange to less than or equal to —12 dBW/4kHz limited to digital carrier transmissions. SES Americom acknowledges that the use of the Prodelin 2.4m 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 transmissions immediately upon notice from the affected parties. !A47 CER. § 25.209 SFS AMEMCOM, nnc_] r,,;R‘_;,V.«:lv:,‘yf Pn._.z_fl NJ 08540 USA ‘ tel {1} 600—987—4000 www.ses—americom.com

Respectfully, / / Director, Satellite Market Development SES Americom Acceptance by Loral: Loral agrees to the use of the Prodelin antenna with an aperture of 2.4 meter, and the power density level into the antenna flange as stated in this letter, with respect to SES Americom satellite transponders that are within +/— 6 degrees orbital spacing from AMC— 2 at 85°WL.
