MONITORING DEVELOPMENT PROGRESS. Through planned design reviews and test activities, Iridium, Inc. will be able to monitor the TND progress. Duplication of testing for the purposes of satisfying requirements of the TND should be avoided. Iridium, Inc. will be afforded the opportunity to attend Gateway Design Reviews and participate in TND testing as described below. The test objectives of the TND contract include verification through test and demonstration that the IRIDIUM Gateway Equipment design meets the Functional Objectives identified in Section 3.1, the Performance Objectives outlined in Section 3.2 and as identified in Appendix A, the services described in Appendix B and the OA&M capabilities listed in Appendix C. The integrated Gateway Equipment will be shown to function as an integral part of the IRIDIUM Communication System. To accomplish the objectives, testing will be performed at four levels. The first testing level is subsystem acceptance testing. This testing will be performed to verify that the suppliers have met the subsystem level requirements. The second level of testing is performed at the Gateway Equipment level by integrating and testing the subsystems together as a functional entity. This level of testing will be performed to verify that the Gateway segment level requirements have been met and all interfaces external to the Gateway have been verified. Simulation will be used for most external interfaces. The third level of testing demonstrates the Gateway Equipment in the Gateway test laboratory. This level of testing introduces other system elements such as the System Control Segment Control Facility, the Message Termination Controller, and the ISU, which replace simulators in the Gateway test laboratory. The objective of this testing is to integrate the Gateway segment into the IRIDIUM Communications System in a laboratory environment. The fourth and final level of testing will be performed to demonstrate the integrated ---------------------------------- * Information has been omitted and filed separately with the Commission pursuant to Rule 406 of the Securities Act of 1933.
