Attached are corrected pages A—12 through A—14 of the narrative technical appendix of the Amendment, with Tables 20bis, 21bis, 27bis, and 28bis. The numerical data presented in these tables are unchanged. However, SES AMERICOM has corrected typographical errors in the description of certain parameters in the tables, revising the parameter labels to reflect the terminology more typically used in reference to analog carriers. SES AMERICOM requests that the attached pages be substituted for the corresponding pages of the Amendment. Please direct any questions regarding this submission to the undersigned. Respectfully submitted, Karis A. Hastings Counsel for SES AMERICOM, Inc.

The solar array will provide sufficient margin to perform the mission over the spacecraft‘s 15—year . life. The original application for AMC—9 provided the end—of—life power budget. Table 30a below provides the beginning—of—life ("BOL") power budget. Page A—14
