B.	Exchange Transaction Overview – Transformation of Ownership Structure
	•	Motient currently holds a 43.4% interest in MSV and a 54.3% interest in TerreStar, and SkyTerra currently holds a 16.2% stake in MSV and an 11.8% interest in TerreStar.
	•	Following the transaction, Motient will own approximately 74% of TerreStar and SkyTerra will own approximately 70% of MSV. Motient ownership of TerreStar could increase to 100% of TerreStar and SkyTerra’s ownership could increase to 100% of MSV if tag along rights are exercised and management options exchanged.
	•	This transaction is a restructuring of the respective ownership structure whereby shareholders will hold the same interests, just in different forms.
	•	By separating the ownership of MSV and TerreStar, each company will be better positioned to pursue their deployment of separate hybrid satellite and terrestrial based communications networks and engage in partnership or other arrangements with potential strategic partners.
	•	MSV will continue to be managed by Alex Good and TerreStar will continue to be managed by Robert Brumley – both of whom, with their respective teams, have strong track records of operational performance.

of Ownership Structure

Transaction Summary – Compelling Rationale

• SIMPLIFIED STRUCTURE:Simplifies ownership structure and removescumbersome minority protections.
   
• ECONOMIC PARITY: NOT A SALE– We view this transaction as anexchange of ownership interests that maintains parity among shareholders. Shareholders will hold substantially unchanged economic interests.
   
• INCREASED VALUE:Expected to facilitate value maximization for eachcompany, and to better enable strategic activity by MSV and TerreStar.
   
• LIQUIDITY:Creates two separate public vehicles, allowing more effectivecapital investment.
   
• COMPETITION:Expected to enhance competitive positioning of bothentities.
   
• SHAREHOLDER CHOICE:Allows Motient stockholders to uncoupleTerreStar and MSV ownership.

Transaction Overview

MSV Exchange Motient exchanges its 43.4% MSV interests for SkyTerra sharesor rights to exchange into SkyTerra shares (the “SkyTerra Put”)representing 50.0% of SkyTerra on a pro forma basis.   Motient will immediately exchange 60.6% of its interest in MSV(26.3% of MSV) for 29.1mm SkyTerra shares, and intendsimmediately, or as soon as practicable, to distribute 25.5mm ofthese SkyTerra shares to its shareholders   39.4% of Motient’s interest in MSV (17.1% of MSV) will beretained. These retained MSV units will be subject to Motient’sexchange rights in the form of the SkyTerra Put, for 18.9mmSkyTerra shares after the initial exchange. Motient will also retainthe 3.5mm shares not distributed to shareholders above, for atotal of 22.5 million shares.   MSV interests retained in order to satisfy obligations uponpotential Preferred conversion and 2006 tax liabilities and forfuture general corporate purposes.   Other MSV unit holders (except TMI) exchange MSV units forSkyTerra ownership. TMI may also exercise tag along right andexchange in transaction.   SkyTerra acquires in aggregate 63.5% of MSV (up from 16.5%)upon initial exchange and 80.6% of MSV assuming exercise ofSkyTerra Put, and possibly to 100% if TMI exercises tag right.

TerreStar Purchase Motient purchases the equity interests of certain investors in TerreStar (excluding SkyTerra and TMI).   While Columbia/Spectrum are the only shareholder parties to the agreements,others TerreStar shareholders (excludingSkyTerra and TMI) are assumed to exercisetag rights in the analysis provided. SkyTerraand TMI may tag as well on to thetransaction.   Motient acquires in aggregate 74.2% of TerreStar (up from 54.3%) with potential for100% ownership if TMI and SkyTerraexercise tag right.

Wall Street Supports Transaction

• “We view the planned exchange to simplify the ownership structure and separate MSV andTerreStar, positively. The transaction simplifies the ownership structure enabling interestedparties to negotiate an investment/acquisition with the majority owner rather than negotiatingwith multiple parties with different demands and requirements.”
  Jefferies & Co. Report (5/15/06)⁽¹⁾
• “We believe this transaction is a positive for both Motient and Skyterra in that it simplifies theownership structures of MSV and TerreStar. We believe the FCC wanted MSV and TerreStarto have distinct majority owners, which prior to this transaction was not the case.”
  Tejas Securities Group Report (5/08/06)⁽¹⁾
• “We believe this deal highlights two catalysts…it lowers the risk of owning Motient shares as itreduces the company’s leverage [and] it improves its access to capital and strategic partners. ”
  Canaccord Adams Report (5/09/06)⁽¹⁾
   
• “On balance, we suspect the simplified ownership structure will accomplish two things: (1) itshould make for easier access to the capital markets and (2) it should also prompt investorsto re-examine the conservative valuations.”
  J. Giordano Securities Group (06/01/06)⁽¹⁾

Management Track Record

The current management team inherited substantial challenges but have achieved significant results. Management has taken Motient from financial instability in 2002/2003 and transformed it into a company that we believe to be best positioned to capitalize on opportunities in the future growth of the MSS/Satellite sector.

• REPORTING:Remedied Motient’s significantly deficient financial reporting – Motient was facing twoyears of restatements and was two years behind in its financial reporting when the current managementtook the helm. Motient has been a timely filer since July 2004.
  
  
• RESTRUCTURING: Facing obsolescence in its DataTac business, management has materiallyreduced the costs and liabilities associated with this business in advance of inevitable revenue decline.
  
  
• FINANCING:Raised over $600 million to support elimination of debt and aggregation of ownershipinterests in MSV and TerreStar at attractive prices relative to today’s market values of MSV andTerreStar.
  
  
• LIABILITY REDUCTION:Management has reduced aggregate liabilities (debt, site lease and other)by over $40 million since 2002/2003. Motient has little liabilities remaining that are associated with theterrestrial business.
  
  
• M&A:Completed 3 principal M&A transactions with over $1.5 billion in value. Announced ExchangeTransaction and sale of terrestrial business have high strategic importance.
  
  
• EQUITY VALUE:Market equity value has increased over 1,000% since 2003 and stock price hasincreased over 500%.

29

Highland’s Destructive Actions

Highland’s Costly Campaign

We Believe Highland’s Plan Will Destroy Shareholder Value:

• Highland has failed to articulate a plan to create value for Motient shareholders.

• Highland’s campaign has been very costly to shareholders.

            –     $2 million in legal fees to fight his six lawsuits. Its Delaware fiduciary duty lawsuit was dismissed and not appealed.

• Highland frequently utilizes costly litigation to wear down its adversaries.

            –    Over 50 lawsuits filed since 2002 alone which are characteristic of this hedge funds’ tactics

• Highland’s interests are not aligned with those of other shareholders.

–     Highland’s investment in Motient competitor, ICO, creates conflict
–     Highland’s lawsuits seek to enrich itself at the expense of other shareholders.
–     Highland fails to disclose these conflicts of interest to shareholders.
–     Highland fails to disclose its investment in transactions that it now criticizes as being mispriced and its benefit from any such mispricing.

• We do not believe that Highland’s interests are the same as shareholders and do not believe installation of their hand-picked Board will be in stockholders’ interests.

• Highland complains about actions that Mr. Dondero was informed about, approved and participated in during his 3.5 years on Motient’s Board.

–    Mr. Dondero approved engagement of CTA, supported engagement of Tejas on two separate occasions (did not support 2005 Convertible Preferred transaction compensation to Tejas and DB but participated in transaction) and approved payments to Mr. Singer.

• Mr. Dondero was informed of and approved company planning calling for revenue decline as a consequence of dispositions, he approved transactions leading to ‘40 Act risk, among numerous other examples.

• Highland will derail valuable MSV and TerreStar opportunities.

31

Summary

• Both companies have plans and management in place to increase shareholder value.
  
  
• Value enhancing transformation of ownership structure critical to plans to unlock futurevalue.

• Motient intends to turn its attention predominantly to TerreStar and the execution of itsbusiness plan.
  
  
• Highland’s attacks on the Company have wasted significant corporate assets and serveHighland’s interests, which we believe conflict with those of other shareholders. Highlandwill derail MSV and TerreStar opportunities.
