SkyTerra Issues Update on Proposed MSV and TerreStar Consolidation

New York, New York, February 2, 2006 – As previously announced, SkyTerra Communications, Inc. (OTC:SKYT) has been pursuing transactions that, if consummated, would result in the consolidation of the ownership of Mobile Satellite Ventures LP (the MSV Joint Venture) and TerreStar Networks, Inc. (TerreStar). To that end, on September 22, 2005, SkyTerra executed a non-binding letter of intent with Motient Corporation (Motient) and the other partners in the MSV Joint Venture and the other stockholders of TerreStar that proposed the basic terms of a consolidation of the ownership of the respective businesses.

While SkyTerra believes the goals of the previously announced consolidation transactions remain in the best interests of the owners of the MSV Joint Venture and TerreStar, including SkyTerra, the structure previously announced for accomplishing these goals will likely need to be modified and that the previously announced consolidation transactions are unlikely to occur as previously contemplated or announced.

SkyTerra is continuing discussions with Motient and the other partners in the MSV Joint Venture and the other stockholders of TerreStar regarding a variety of potential structures to effect the consolidation of ownership of the MSV Joint Venture and TerreStar. Consummation of any consolidation transactions will require successful completion of due diligence, negotiation and execution of definitive documentation and various regulatory approvals, and may also require the approval of the stockholders of one or more of the parties to the transactions. SkyTerra can provide no assurances that any consolidation transaction will be consummated, or that the required corporate or regulatory approvals will be obtained.
