[LOGO OMITTED] SPACE SYSTEM - ------------ LORAL [LOGO OMITTED] TerreStar Networks EXECUTION COPY Notwithstanding the foregoing, if the SBN is determined upon completion of the Final SBN IOT to be a Partially or Fully Degraded SBN (based on the SBN Key Performance Requirements adjusted in accordance with Article 9.1.4 A) due in whole or material part to the failure of the Satellite to meet the requirements of the Satellite Performance Specification defined in the Satellite Contract, then the maximum reduction to the SBN Acceptance Payment shall be [***] U.S. dollars (US$[***]), subject to adjustment in accordance with Article 33.1. Further, if each of the Satellite and the SBAS Operational Component contributes significantly to the degradation in SBN performance, the Parties shall negotiate in good faith to equitably adjust amounts payable hereunder, which equitable amount shall be consistent with limiting Contractor's risk associated with the Satellite-related degradations to the SBN Performance to [***] U.S. dollars (US$[***]) (subject to adjustment in accordance with Article 33.1) as set forth above. Notwithstanding the foregoing, if prior to Acceptance of the SBN and SBN Work, as a result of any act or omission on the part of Purchaser or Purchaser's representatives, consultants or subcontractors (including the Launch Agency, as defined in the Satellite Contract, but excluding Contractor and any of its subcontractors at any tier) in the launch, orbit-raising, operation of, testing of, or communication with, any Satellite, or operation of, testing of, or communication with the SBAS Operational Component or if due solely to causes not attributable to Contractor or its subcontractors (other than extraordinary events customarily listed as "Exclusions" under launch and in-orbit insurance policies), such SBN is determined to be a Partially Degraded SBN or Fully Degraded SBN, Contractor shall be deemed to have earned the amount of the SBN Acceptance Payment that would have been earned but for such event, act or omission resulting in the SBN being a Partially or Fully Degraded SBN.

During a system design phase of the satellite ground segment procurement (SGS) contract, Contractor may propose refinements and alterations to this plan in consultation with Purchaser. Contractor will define the GBBF performance testing during the system design phase and the deliverable from this activity shall be a GBBF Test Plan. The GBBF Test Plan must encompass, at least at a high level, the performance tests described here. During the system design phase, other tests may be proposed, as appropriate. In terms of network topology, the GBBF is sandwiched between the S-BSS and the Satellite; Calibration Earth Stations (CES's) connect to the far side of the satellite network, as well as to the GBBF. Therefore, in order to test the GBBF before the real network is available, an S-BSS Emulator and a Satellite Simulator (SS) are required. These shall be developed as Deliverable Items under this Contract. The salient characteristics of the S-BSS Emulator and the SS are described in the following sections. Figure 1.1 shows the test setup.

[LOGO OMITTED] SPACE SYSTEMS - ------------- LORAL [LOGO OMITTED] TerreStar EXECUTION COPY Networks ---------------- 1 -- SCOPE This document is a verification and test plan for the TerreStar Space Based Network. 1.1 OVERVIEW The TerreStar Space Based Network (SBN) is comprised of a TerreStar Satellite, provided pursuant to the Satellite Contract, and a Satellite Beam Access System (SBAS). The SBAS comprising of 2 Feeder-link Earth Stations (FES) including: o Gateway (RF and IF equipment) o Ground Based Beam Forming (GBBF) o Control system o Terrestrial telecom facility o TT&C interfaces The GBBF consists of components within a TerreStar Gateway and a number (TBD) of Calibration Earth Stations (CES). The TerreStar Satellite performance is verified during development and on orbit as per the Test Plan in Exhibit D to the Satellite Contract and the associated documents detailing the test procedures. On the same lines, the SBAS and the GBBF Subsystem performance is verified per the GBBF in Exhibit D-1 and its associated documents on test procedures. The verification of the SBN In Orbit Test will closely follow the Satellite IOT and the SBAS Preliminary Acceptance and will consist of end-to-end tests intended to verify the SBN functionalities and performance prior to its commissioning within the TerreStar Hybrid Network. Selected tests conducted during SBN IOT shall be compared with baseline test results determined during SBAS Tests. Figure 1-1 provides an overview of the relationship between the development & test of the Space Based Network and its components. This document provides the overall requirements for the SBN Test Plan. Detailed test procedures for SBN-related tests shall be developed as required by Exhibit A-2, SBN Statement of Work. These procedures will be cross-referenced to the corresponding procedures for tests at the SBAS level conducted with the Satellite Simulator.
