      The
Company and the Investor have entered into that certain Master Contribution and
Support Agreement, dated as of July 24, 2008, among the Company, the Investor,
Harbinger Capital Partners Master Fund I, Ltd., Harbinger Capital Partners
Special Situations Fund, LP and Mobile Satellite Ventures Subsidiary LLC (the

      The
MCSA provides that that the parties hereto shall enter into this Agreement
pursuant to which the Company shall sell to the Investor, and the Investor shall
purchase from the Company, shares of the Company’s voting common stock, par
value $0.01 per share (the “Voting
Common Stock”) on the terms and subject to the conditions as set forth
herein;

      

      NOW, THEREFORE, in consideration of
the premises, mutual covenants and agreements hereinafter contained and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

       

      ARTICLE
I

      ISSUANCE
OF SHARES

       

      1.1    Purchase and Sale of
Shares.  Subject to the terms and conditions of this Agreement,
the Investor agrees to purchase at the Closing, and the Company agrees to sell
and issue to the Investor at the Closing, free and clear of any and all
Encumbrances, that number of shares of Voting Common Stock (the “Purchased
Shares”) equal to (x) the Cash Purchase Price (as hereinafter defined)
divided by (y) the Agreed Issue Price.  On the Closing Date, the
Investor shall pay to the Company an amount in cash equal to the Cash Purchase
Price, which shall be paid by wire transfer of immediately available funds into
an account designated in writing by the Company not less than three Business
Days prior to the Closing Date and concurrently therewith, the Company shall
issue and deliver to the Investor the Purchased Shares.

       

      For purposes of this Agreement, (a)
except as otherwise provided in Section 1.2, the “Cash
Purchase Price” shall equal up to the greater of (i) USD$2,400,000,000 or
(ii) such other amount as the Investor may determine, in either case minus the aggregate
gross proceeds of the Financing Rights Offering to the extent such amount is
received prior to Closing, and (b) subject to adjustment as provided in Section
1.3, the price per share of Voting Common Stock (the “Agreed
Issue Price”) shall equal the product of (i) USD$10.00, multiplied by (ii) a
fraction, (A) the numerator of which shall be the Target Offer Price and (B) the
denominator of which shall be 535.3p.

       

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

       

      1.2    Notification of Cash
Purchase Price.  The Investor shall notify the Company of the
Cash Purchase Price pursuant to a Notification and, if applicable, an Amendment
Notification, delivered in accordance with the terms of the MCSA.  In
the event that the Investor determines (having taken into account the amount of
available Debt Financing, as defined in and pursuant to the MCSA), that less
cash is required to pay the Firm Offer Costs, the Investor shall have the right
to reduce the Cash Purchase Price and shall notify the Company of such reduction
by Notification or Amendment Notification, as applicable.

      

      1.3    Adjustment of Agreed Issue
Price.  The Agreed
Issue Price shall be equitably adjusted to reflect any changes to the
Company's capital structure that may occur between the date hereof and the
Closing, provided, however, that no such adjustment shall be made for any shares
of Common Stock issued by the Company to Harbinger in exchange for the
Contribution Assets, the Sponsor Fee Shares and any warrants granted to
Harbinger pursuant to the Securities Purchase Agreement. Such changes to the
Company's capital structure may include, but are not limited to, stock
consolidations, stock splits, interim rights offerings, non-cash distributions,
spin-offs, reclassifications, schemes of arrangements, payments of cash
dividends or other similar transactions.

      

      1.4    Use of
Proceeds.  The Company agrees that the net proceeds from the
purchase and sale of the Purchased Shares shall be used solely to pay the Firm
Offer Costs.

       

      ARTICLE
II

      CLOSING

      
        

        2.1    Closing.  The
closing of the transactions described in Section 1.1 (the “Closing”)
will take place at the offices of Weil, Gotshal & Manges LLP, 767 Fifth
Avenue, New York, NY 10153 on the date (the “Closing

writing.

the Closing, the Company shall deliver to the Investor certificates representing
the Purchased Shares, issued in the name of the Investor or its nominee and
otherwise sufficient to transfer the Purchased Shares to the Investor free and
clear of all Encumbrances arising out of any act of the
Company.

      ARTICLE
IV

      INVESTOR
REPRESENTATIONS AND WARRANTIES

       

      The
Investor hereby makes the following representations and warranties as of the
date hereof:

       

       

      
        
          
          

        

        
          2

          
            

          

        

        
          
          

        

      

       

       

      4.1    Purchase Entirely for Own
Account.  Except insofar as rights are conferred on any other
participants of the Investor under the rules of that fund, (i) the Investor is
acquiring the Purchased Shares for its own account for investment and not for
the account of any other Person or with a view to any resale, fractionalization,
division, or distribution thereof in a manner that would require registration
thereof under the Securities Act of 1933, as amended (the “Securities
Act”), and the Investor presently has no reason to anticipate any change
in its circumstances or other particular occasion or event which would cause it
to sell the Purchased Shares other than in compliance with the requirements of
the Securities Act; and (ii) the Investor has no contract, undertaking,
agreement, understanding or arrangement with any Person to sell, transfer, or
pledge to any Person any part or all of the Purchased Shares which the Investor
is acquiring, or any interest therein, and has no present plans to enter into
the same.  The Purchased Shares were not offered or sold to the
Investor by means of any general solicitation or general
advertisement.

       

      4.2    Investor Status;
Etc.  The Investor certifies and represents to the Company that
it is an “accredited investor” as defined in Rule 501(a) of Regulation D
promulgated under the Securities Act.  The Investor has adequate means
of providing for its current needs and personal contingencies, has no need now,
and anticipates no need in the foreseeable future, to sell the Purchased Shares,
and currently has sufficient net worth and financial liquidity to afford a
complete loss of its investment in the Company.  The Investor has such
knowledge and experience in financial and business matters so that it is capable
of evaluating the merits and risks of an investment in the Company and has made
such evaluation.  The Investor fully understands that the Purchased
Shares are speculative investments which involve a high degree of risk of loss
of the Investor’s entire investment.  No Person or entity, other than
the Company or its authorized representatives, has offered the Purchased Shares
to the Investor.  The Investor is able to bear the economic risk of an
investment in the Purchased Shares.

       

      4.3    Securities Not
Registered. The Investor understands that Purchased Shares have not been
registered under the Securities Act by reason of their issuance by the Company
in a transaction exempt from the registration requirements of the Securities
Act, and that the Purchased Shares must continue to be held by the Investor
unless a subsequent disposition thereof is registered under the Securities Act
or is exempt from such registration. The Investor understands that the
exemptions from registration afforded by Rule 144 promulgated under the
Securities Act (the provisions of which are known to it) depend on the
satisfaction of various conditions, and that, if applicable, Rule 144 may afford
the basis for sales only in limited amounts.  The Investor has had an
opportunity to ask questions of and receive answers from the management and
authorized representatives of the Company, and to review any other relevant
documents and records concerning the business of the Company and the terms and
conditions of this investment, and that any such questions have been answered to
the Investor’s satisfaction.  The Investor understands that no federal
or state agency has passed upon or made any recommendation or endorsement of an
investment in the Purchased Shares.

RESTRICTIONS

       

      5.1    Restrictions on
Transfers.  Purchased Shares shall not be transferred, sold,
assigned, exchanged, mortgaged, pledged, hypothecated, or otherwise disposed of
or encumbered without compliance with, and they are otherwise restricted by, the
provisions of the

      Securities
Act, the rules and regulations thereunder and this Agreement.  Each
certificate, if any, evidencing such Purchased Shares issued upon any such
Transfer, other than in a public offering pursuant to an effective registration
statement, shall bear the restrictive legend set forth in Section 5.2(a), unless
the Holder thereof delivers to the Company an Opinion of Counsel to the effect
that such legend is not required for the purposes of compliance with the
Securities Act.  Holders of Purchased Shares shall not be entitled to
Transfer such Purchased Shares except in accordance with this Article
V.

       

      5.2    Restrictive
Legends.

       

      (a)    Each
certificate for the Purchased Shares shall be stamped or otherwise imprinted
with two legends in substantially the following forms:  "THE SECURITIES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER UNDER THE SECURITIES ACT OF
1933, AS AMENDED, AND STATE SECURITIES LAWS, AND MAY NOT BE OFFERED FOR SALE,
SOLD, ASSIGNED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF UNLESS (I)
REGISTERED UNDER THE APPLICABLE SECURITIES LAWS OR (II) SUCH TRANSACTION IS
EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND AN
OPINION OF COUNSEL, WHICH OPINION IS REASONABLY SATISFACTORY TO THE COMPANY, HAS
BEEN DELIVERED TO THE COMPANY AND SUCH OPINION STATES THAT THE SECURITIES MAY BE
TRANSFERRED WITHOUT SUCH REGISTRATION."

       

      (b)    The
legend requirements of Section 5.2(a) shall terminate as to any certificate for
Purchased Shares when the Company shall have received from the holder thereof an
opinion of counsel to the effect that such legend is not required in order to
ensure compliance with the Securities Act, and the holder of such certificate
for the Purchased Shares shall be entitled to receive from the Company, at the
expense of the Company, a new certificate for the Purchased Shares without the
legend provided for in Section 5.2(a).

       

      (c)    All
certificates for Purchased Shares issued upon registration of transfer, division
or combination of, or in substitution for, any other certificates for Purchased
Shares entitled to bear the legend provided for in Section 5.2(a) shall have a
similar legend endorsed thereon.

      Material Adverse Effect.  No suspension or cancellation of any of the
      Permits is pending or, to the knowledge of the Issuers, threatened, which would,
      individually or in the aggregate, reasonably be expected to have a Material
      Adverse Effect.  The Issuers believe they can obtain, without undue
      burden or expense, any similar authority for the conduct of their business
      as
      presently proposed to be conducted as of the date hereof.  The Issuers

      MSV nor any or its Subsidiaries nor any entity which is considered one employer
      with MSV under Section 4001 of ERISA or Section 414 of the Code (i) maintains
      or
      contributes to or has within the past six years maintained or contributed to
      a
      Pension Plan that is subject to Subtitles C or D of Title IV of ERISA or (ii)
      maintains or has an obligation to contribute to or has within the past six

      the level of the expense incurred therefor for the most recent fiscal
      year.

     

    (e)           Each
      Benefit Plan complies in form and has been operated in substantial compliance
      with its terms and the requirements of ERISA, the Code and other

    Each
      Benefit Plan which is subject to ERISA (the “ERISA Plans”) that is
      an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA
      (“Pension
      Plan”) and that
      is intended to be qualified under Section 401(a) of the Code, has received
      a
      favorable determination letter from the IRS, or is comprised of a master or
      prototype plan that has received an opinion from the IRS, covering all
      tax  Law changes prior to the Economic Growth and Tax Relief
      Reconciliation Act of 2001 or has applied to the IRS for such favorable
      determination letter within the applicable remedial amendment period under
      Section 401(b) of the Code, and to the best knowledge of MSV no event has
      occurred that would reasonably be expected to result in revocation of any such
      favorable determination letter or the loss of the qualification of such ERISA
      Plan under Section 401(a) of the Code.  To the Issuers’ knowledge,
      neither MSV nor any of its Subsidiaries has engaged in a transaction with
      respect to any ERISA Plan that, assuming the taxable period of such transaction
      expired as of the date hereof, could subject MSV or any Subsidiary to a tax
      or
      penalty imposed by either Section 4975 of the Code or Section 502(i) of ERISA
      in
      an amount which would be material. Neither MSV nor any of its Subsidiaries
      has
      incurred or reasonably expects to incur a material tax or penalty imposed by
      Section 4980F of the Code or Section 502 of ERISA.

     

    (f)           Except
      as set forth in Section 4.25(f) of
      the Disclosure Schedules, as of the date hereof, there is no material pending
      or, to the best knowledge of the Issuers, threatened litigation relating to
      the
      Benefit Plans. Neither MSV nor any of its Subsidiaries has any obligations
      for
      retiree health and life benefits under any Benefit Plan or collective bargaining
      agreement. MSV or its Subsidiaries may amend or terminate any such plan at
      any
      time without incurring any liability thereunder other than in respect of claims
      incurred prior to such amendment or termination.

     

    (g)           Neither
      the execution of this Agreement nor the consummation of the transactions
      contemplated herein will (w) entitle any employees of MSV or any of its
      Subsidiaries to severance pay or any increase in severance pay upon any
      termination of employment after the date hereof, (x) accelerate the time of
      payment or vesting or result in any payment or funding (through a grantor trust
      or otherwise) of compensation or benefits under, increase the amount payable
      or
      result in any other material obligation pursuant to, any of the Benefit Plans,
      (y) limit or restrict the right of MSV or any of its Subsidiaries to merge,
      amend or terminate any of the Benefit Plans or (z) result in payments under
      any
      of the Benefit Plans which would not be deductible under Section 162(m) or
      Section 280G of the Code. No Benefit Plan or other agreement provides any
      employee, director or other service provider of MSV or its Subsidiaries with
      any
      amount of additional compensation if such individual is provided amounts subject
      to excise or additional taxes imposed under Sections 409A or 4999 of the
      Code.

     

    (h)           Neither
      MSV nor any of its Subsidiaries has any material liability by reason of an
      individual who performs or performed services for MSV or any of its Subsidiaries
      in any capacity being improperly excluded from participating in a Benefit Plan;
      and each of the employees of MSV and its Subsidiaries has been properly
      classified by MSV and its Subsidiaries as “exempt” or “non-exempt” under
      applicable Law.

      respective employees, on the other hand, and MSV has not experienced any such
      strike, slowdown or work stoppage within the past three (3) years.

     

    (c)           Neither

      Effect.

      all applicable Laws relating to the employment of labor, including those related

      and
      authorizations necessary to work in the United States in accordance with
      applicable Law.

     

    (g)           Each

      reserved in accordance with MSV’s historical accounting practices, policies and
      principles consistently applied, all wages, salaries, commissions, bonuses,

      been asserted or, to the best knowledge of the Issuers, is now pending or

      on
      such date (i) the then present fair market value (or then present fair saleable
      value) of the assets of such entity is not less than the total amount required

      reasonably available to such entity; (ii) assuming consummation of the issuance

      liabilities mature; (iii) such entity is not engaged in any business or
      transaction, and does not propose to engage in any business or transaction,
      for
      which its property would constitute unreasonably small capital after giving
      due
      consideration to the prevailing practice in the industry in which such entity
      is
      engaged; and (iv) such entity is not a defendant in any civil action that would
      result in a judgment that such entity is or would become unable to
      satisfy.

      13,139,696 shares of Common Stock are reserved for future issuance pursuant
      to
      outstanding warrants issued by SkyTerra.  As of the date hereof, a
      total of 11,030,259 additional shares of Common Stock are authorized and
      reserved for future issuance pursuant to option and other equity plans adopted
      or approved by SkyTerra.  As of the date hereof, except as further
      disclosed in Section
      4A.4 of the Disclosure Schedules or for the right to purchase SkyTerra
      Common Stock upon exercise of the Warrants, there are no other outstanding
      options, warrants, rights (including conversion or preemptive rights) or any
      agreement for the purchase or acquisition from SkyTerra of any shares of
      SkyTerra’s capital stock or voting agreements with respect to equity of SkyTerra
      or any of its Subsidiaries.  All outstanding shares of the capital
      stock of SkyTerra have been duly authorized, validly issued, fully paid and
      nonassessable.  Except as disclosed in Section 4A.4 of the
      Disclosure Schedules, there are no obligations, contingent or otherwise, of
      SkyTerra or its Subsidiaries to repurchase, redeem or otherwise acquire any
      shares of Common Stock or other equity securities of SkyTerra or its
      Subsidiaries.  Except as disclosed in Section 4A.4 of the
      Disclosure Schedules, the sale of the Warrants, and the issuance of any Common
      Stock upon exercise of the Warrants, will not result in SkyTerra being obligated
      to issue, sell or purchase, pursuant to any existing pre-emptive, anti-dilution,
      redemption or other right of third parties, shares of Common Stock or other
      securities to or from any Person (other than the Purchasers), and will not
      result in a right of any holder of convertible or contingent securities issued
      by SkyTerra to adjust the exercise, conversion, exchange or reset price under
      such securities, including, in any such case, pursuant to any “poison pill” or
      shareholders rights plan.  As of the date hereof, except as set
      forth in outstanding warrants or as disclosed in Section 4A.4 of the
      Disclosure Schedules, there are no anti-dilution or price adjustment provisions
      contained in any security issued by SkyTerra (or in any agreement providing
      rights to security holders). None of

      shares of Common Stock issuable upon exercise of the Warrants in accordance
      with
      the terms of the Warrants have been (or will, by the First Closing Date, be)
      duly authorized by SkyTerra and, when delivered in accordance with the terms
      of
      the Warrants (a) will be validly issued, fully paid and nonasessable, (b)
      assuming the waiver by the Purchasers of certain preemptive rights pursuant

      without regard to the exceptions set forth in clauses (a) and (b) of the
      definition of Encumbrance) which are imposed by SkyTerra, or arise as a result
      of SkyTerra’s action or omission.  SkyTerra has reserved from its duly
      authorized capital stock the number of shares of Common Stock issuable upon
      the
      exercise in full of the Warrants.

     

    (b)           The
      shares of Voting Common Stock issuable upon exchange of the shares of Non-Voting
      Common Stock in accordance with the terms of Section 8.1 hereof

      which are imposed by SkyTerra, or arise as a result of SkyTerra’s action or
      omission.  SkyTerra has reserved from its duly authorized capital
      stock the number of shares of Common Stock issuable upon the exchange in full
      of
      the Non-Voting Common Stock.

     

    4A.6              Approvals.  Assuming
      the accuracy of the Purchasers’ representations and warranties set forth in
Section
      5 below, except (a)
      in connection with or in order to comply with the applicable provisions of
      the
      Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) and, if
      necessary, similar foreign competition or Antitrust Laws, and if necessary,
      any
      required stock exchange approvals, (b) for any required filings and recordings
      which have been made and are in full force and effect, (c) for applicable blue
      sky notice filings, and (d) the consents, approvals, authorizations, orders,

      validation of, or filing, recording or registration with, or exemption by,
      any

      or
      as a condition to (i) the execution and delivery of the Transaction Documents
      or
      the consummation of the issuance and sale of the Warrants contemplated hereby
      or
      (ii) the legality, validity, binding effect or enforceability of the Transaction
      Documents.  The execution and delivery by SkyTerra of this Agreement
      and the issuance of the Warrants do not require the consent or approval of
      the
      security holders of SkyTerra or of any other Person.

    4A.7              Conformity
      to
      Securities Act
      and Exchange Act; No Misstatement or Omission.  As of its
      filing date or, if amended prior to the date of this Agreement, as of the date
      of the last such amendment prior to the date of this Agreement, each of the
      SEC
      Reports complied in all material respects with the applicable requirements
      of
      the Securities Act or the Exchange Act (as applicable) and the respective rules
      and regulations of the SEC thereunder, as in effect on the date so filed, and
      does not contain an untrue statement of a material fact or omit to state a
      material fact necessary in order to make the statements therein not
      misleading.  Since December 31, 2007, SkyTerra has filed all reports,
      schedules, forms, statements and other documents required to be filed by it
      with
      the SEC pursuant to the reporting requirements of the Exchange Act.

     

    4A.8              Financial
      Statements;
      Indebtedness.

     

    (a)           Except
      as disclosed in
      Section 4A.8(a) of the Disclosure Schedules, the financial statements and
      supporting schedules included in SkyTerra’s Annual Report on Form 10-K for the
      year ended December 31, 2007 and the Amendment to the SkyTerra 's Annual Report
      for the year ended December 31, 2007 on Form 10-K/A, and in SkyTerra’s Quarterly
      Report on Form 10-Q for the quarter ended March 31, 2008, in each case filed
      with the SEC present fairly, in all material respects, the consolidated
      financial position of SkyTerra as of the dates specified and the consolidated
      results of their operations and cash flows for the periods specified, in each
      case, in conformity with GAAP applied on a consistent basis during the periods
      involved, except as indicated therein or in the notes thereto.

     

    (b)           Except
      for Indebtedness disclosed in Section 4A.8(b) of
      the Disclosure Schedules and in SkyTerra’s Annual Report on Form 10-K for the
      year ended December 31, 2007, and in SkyTerra’s Quarterly Report on Form 10-Q
      for the quarter ended March 31, 2008, SkyTerra has no material Indebtedness
      outstanding at the date hereof.  SkyTerra is not in default with
      respect to any outstanding Indebtedness or any instrument relating thereto,
      and
      no event has occurred, or facts and circumstances exist, which, after passage
      of
      time or giving of notice, would result in such a default.

     

    4A.9              Internal
      Accounting
      Controls.  SkyTerra maintains a system of internal accounting
      controls sufficient to provide reasonable assurance that (i) transactions are
      executed in accordance with management’s general or specific authorizations,
      (ii) transactions are recorded as necessary to permit preparation of financial
      statements in conformity with GAAP and to maintain asset accountability, (iii)
      access to assets is permitted only in accordance with management’s general or
      specific authorization, and (iv) the recorded accountability for assets is
      compared with the existing assets at reasonable intervals and appropriate action
      is taken with respect to any differences.  SkyTerra has established
      disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e))
      for SkyTerra and designed such disclosure controls and procedures to ensure
      that
      information required to be disclosed by SkyTerra in reports that it files or
      submits under the Exchange Act is recorded, processed, summarized and reported
      within the time periods specified in the SEC’s rules and forms, including
      controls and procedures designed to ensure that such information is accumulated
      and communicated to SkyTerra’s management as appropriate to allow timely
      decisions regarding required disclosure.  SkyTerra has carried out
      evaluations of the effectiveness of their disclosure controls and procedures
      as
      required by Rule 13a-15 of the Exchange Act.

    5.           Representations
      and Warranties of the
      Purchasers.  The
      Purchasers hereby make the following representations and warranties, as of
      the
      date hereof and as of each of the Closing Dates:

     

    5.1           Authorization.  All
      corporate, partnership or limited liability company action on the part of each
      of the Purchasers necessary for the authorization, execution, delivery and
      performance of this Agreement and the other Transaction Documents and the
      consummation of the transactions contemplated herein and therein, has been
      taken.  When executed and delivered by such Purchasers, each of this
      Agreement and the other Transaction Documents shall constitute the legal, valid
      and binding obligation of each of the Purchasers, enforceable against each
      of
      the Purchasers in accordance with its terms, except as such may be limited
      by
      bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights
      generally and by general equitable principles.  Each of the Purchasers
      has all the requisite corporate power and authority to enter into each of this
      Agreement and the other Transaction Documents and to carry out and perform
      its
      obligations under the terms hereof and thereof.

     

    5.2           Purchase
      Entirely for
      Own
      Account.  Each of the Purchasers is acquiring the Securities
      for its own account for investment and not for the account of any other Person
      or with a view to any resale, fractionalization, division, or distribution
      thereof in a manner that would require registration thereof or the transactions
      contemplated hereby under the Securities Act, and neither Purchaser presently
      has any reason to anticipate any change in such Purchaser’s circumstances or
      other particular occasion or event which would cause such Purchaser to sell
      the Securities other than in compliance with the requirements of the Securities
      Act.  The Purchasers have no contract, undertaking, agreement,
      understanding or arrangement with any Person to sell, transfer, or pledge to
      any
      Person any part or all of the Securities which such Purchasers are acquiring,
      or
      any interest therein, and have no present plans to enter into the
      same.  The Securities were not offered or sold to the Purchasers by
      means of any general solicitation or general advertisement.

     

    5.3           Investor
      Status;
      Etc.  The Purchasers certify and represent to the Issuers that
      (i) they are each an “accredited investor” as defined in Rule 501(a)(1), (2),
      (3) or (7) of Regulation D promulgated under the Securities Act and were not
      organized for the purpose of acquiring any of the Securities.  The
      Purchasers have adequate means of providing for their current needs and personal
      contingencies, have no need now, and anticipate no need in the foreseeable
      future, to sell the Securities, and currently have sufficient net worth and
      financial liquidity to afford a complete loss of their investment in the Issuers
      and SkyTerra.  The Purchasers have such knowledge and experience in
      financial and business matters so that the Purchasers are capable of evaluating
      the merits and risks of an investment in the Issuers and SkyTerra and have
      made
      such evaluation.  The Purchasers fully understand that the Securities
      are speculative investments which involve a high degree of risk of loss of
      the
      Purchasers’ entire investment.  No Person or entity, other than
      the Issuers or their authorized representatives, have offered the Securities
      to
      the Purchasers.    The Purchasers are able to bear the
      economic risk of an investment in the Securities.

     

    5.4           Securities
      Not Registered.
      The
      Purchasers understand that neither the Securities nor the Warrant Stock issuable
      upon exercise of the Warrants or the Voting Common Stock issuable upon exchange
      of Warrant Stock that is Non-Voting Common Stock

    
      
        
           
            

        

        
          22

          
            

          

        

        
           
            

        

      

    

     

    have
      been registered under the Securities Act, by reason of their issuance by the
      Issuers in a transaction exempt from the registration requirements of the
      Securities Act, and that the Securities must continue to be held by the
      Purchaser unless a subsequent disposition thereof is registered under the
      Securities Act or is exempt from such registration. The Purchasers understand
      that the exemptions from registration afforded by Rule 144 promulgated under
      the
      Securities Act (the provisions of which are known to it) depend on the
      satisfaction of various conditions, and that, if applicable, Rule 144 may afford
      the basis for sales only in limited amounts.  The Purchasers have had
      an opportunity to ask questions of and receive answers from the management
      and
      authorized representatives of the Issuers and SkyTerra, and to review any
      other relevant documents and records concerning the business of the Issuers
      and
      SkyTerra and the terms and conditions of this investment, and that any such
      questions have been answered to the Purchasers’ satisfaction.  The
      Purchasers understand that no federal or state agency has passed upon or made
      any recommendation or endorsement of an investment in the
      Securities.

     

    5.5           No
      Violation.  Neither the execution, delivery and performance by
      such Purchasers of this Agreement or the Transaction Documents nor compliance
      with the terms and provisions hereof and thereof by the Purchasers (a) will
      contravene any applicable provision of any Law applicable to the Purchasers,
      except as would not have a material adverse effect on the Purchasers’
ability to consummate the transactions contemplated hereby or (b) will violate
      any provision of the organizational documents of the Purchasers, except as
      would
      not have a material adverse effect on the Purchasers’ ability to consummate
      the transactions contemplated hereby.

     

    5.6           Brokers.
      The
      Purchasers have no liability to pay any fees, commissions or other similar
      compensation to any broker, finder, investment banker, financial advisor or
      other similar Person in connection with the transactions contemplated by this
      Agreement, other than Merrill Lynch & Co., all fees of which shall be paid
      by the Purchasers.

     

    5.7           Consents.
      Except (a)
      in connection with or in order to comply with the applicable provisions of
      the
      HSR Act and, if necessary, similar foreign competition or Antitrust Laws, and
      (b) for any required filings and recordings with Governmental Authorities under
      Section 6, all
      consents, approvals, orders and authorizations required on the part of the
      Purchasers in connection with the execution, delivery or performance of this
      Agreement and the consummation of the transactions contemplated herein have
      been
      obtained and are effective as of the date hereof.

     

    5.8           Reliance.
      The
      Purchasers are relying solely upon the advice of their own financial, legal
      and
      Tax advisors and their entering into the transactions contemplated by this
      Agreement is the result of independent arm’s length negotiations among the
      Purchasers, SkyTerra and the Issuers.  The Purchasers acknowledge that
      the Issuers and SkyTerra are relying on the representation and warranties of
      the
      Purchaser contained in this Section 5 and would
      not consummate the transactions contemplated by this Agreement in the absence
      of
      the representations and warranties of the Purchaser contained in this Section
      5.

     

    5.9           Material
      Non-Public
      Information. The Purchasers hereby acknowledge that they are familiar
      with their responsibilities under federal and state securities laws
      relating

     

    
      
         
          

      

      
        23

        
          

        

      

      
         
          

      

    

     

    to
      restrictions on trading in securities of an issuer while in possession of
      material, non-public information, and restrictions on sharing such information
      with other Persons who may engage in such trading.

     

    5.10         16.5%
      Notes.
 The Purchasers represent and warrant that they are the sole holders
      of all
      of the Issuers’ outstanding 16.5% Notes due 2013 (the “16.5% Notes”),
      including any additional 16.5% Notes issued after January 7, 2008 as
      paid-in-kind interest, issued pursuant to the 16.5% Notes Indenture, free
      and clear of any lien, pledge or encumbrance of any kind.  Each
      Purchaser consents to amend the 16.5% Notes Indenture as set forth in the 16.5%
      Notes Supplemental Indenture and agrees to take such actions as are reasonably
      necessary in order to effectuate the 16.5% Notes Supplemental Indenture as
      soon
      as reasonably practicable after the date hereof.

     

    6.           Governmental
      and FCC
      Approval.  The
      parties will promptly execute and file, or join in the execution and filing
      of,
      any application, notification or other document that may be necessary in order
      to obtain the authorization, approval or consent of any Governmental Authority,
      which may be reasonably required in connection with the consummation of the
      transactions contemplated by this Agreement.  Any fees associated with
      such notifications or applications shall be borne by the
      Issuers.  Each party shall, in connection with its obligation to use
      commercially reasonable efforts to obtain, or assist the other parties in
      obtaining, all such requisite authorizations, approvals or consents, use
      commercially reasonable efforts to (i) cooperate in all reasonable respects
      with
      the other parties in connection with any filing or submission and in connection
      with any investigation or other inquiry, including any proceeding initiated
      by a
      private party, (ii) promptly inform the other parties of any communication
      received by such party from, or given by such party to, the United States
      Department of Justice (the “DOJ”), the United
      States Federal Trade Commission (the “FTC”), the FCC
      or any
      other Governmental Authority or quasi-governmental entity and of any material
      communication received or given in connection with any proceeding by a private
      party, in each case regarding any of the transactions contemplated hereby,
      (iii)
      permit the other parties, or the other parties’ legal counsel, to review any
      communication given by it to, and consult with the other parties in advance
      of

      (without giving effect to any limitation on any representation and warranty
      indicated by a materiality qualification, including the words "Material Adverse
      Effect," "material," "in all material respects" or like words) as of such
      Closing Date with the same effect as though made on and as of such Closing

      on
      any representation and warranty indicated by a materiality qualification,

      Covenants and
      Agreements.

     

    8.1           Non-Voting
      Common
      Stock.

     

    (a)           SkyTerra
      shall reserve and keep available for issuance upon and until the exercise of
      the
      January Warrants at least such number of its authorized but unissued shares
      of
      Non-Voting Common Stock as would be sufficient to exercise the January Warrants
      in full for shares of Non-Voting Common Stock then issuable pursuant to the
      January Warrants. SkyTerra shall use its commercially reasonable best
      efforts to cause its Certificate of Incorporation to be amended to increase
      the
      number of shares of Non-Voting Common Stock authorized for issuance thereunder
      so as to permit the April Warrants to be exercised in full for shares of
      Non-Voting Common Stock (the “Amendment”). From and
      after the effective date of the Amendment under Delaware law (the “Effective Date”),
      SkyTerra shall reserve and keep available for issuance upon and until the
      exercise of the Warrants at least such number of its authorized but unissued
      shares of Non-Voting Common Stock as would be sufficient to exercise the
      Warrants in full for shares of Non-Voting Common Stock then issuable pursuant
      to
      the Warrants.

     

    (b)           The
      Purchasers shall, and shall cause all of their Affiliates to, vote in favor
      of
      or consent in writing to the Amendment in respect of all shares of Common Stock
      over which they and their Affiliates have the power to vote.

     

    (c)           If,
      on the First Closing Date and thereafter until (but excluding) the Second
      Closing Date, SkyTerra does not have at least 7,500,000 shares of Non-Voting
      Common Stock (such amount to be adjusted to reflect any changes in the amount
      of
      shares of Common Stock for which the Warrants may be exercised as a result
      of
      the antidilution provisions of the Warrants) authorized but unissued (and not
      otherwise reserved for issuance), less the number of shares of Common Stock
      for
      which Warrants have theretofore been exercised, then, during the period from
      the
      First Closing Date to the Effective Date, the rate of interest paid by the
      Issuers on the Notes pursuant to Section 2 hereof
      shall increase to 16.50% per annum for a period of 90 days, and to 17.0%
      thereafter, until the Effective Date.

     

    (d)           If,
      on the Second Closing Date and thereafter until the earlier of the Effective
      Date and July 1, 2013, SkyTerra does not have at least 25,000,000 shares of
      Non-Voting Common Stock (such amount to be adjusted to reflect any changes
      in
      the amount of shares of Common Stock for which the Warrants may be exercised
      as
      a result of the antidilution provisions of the Warrants) authorized but unissued
      (and not otherwise reserved for issuance), less the number of shares of Common
      Stock for which Warrants have theretofore been exercised, then, during the
      period from the Second Closing Date to the earlier of the Effective Date or
      the
      date of the repayment in full of the Notes, the rate of interest paid by the
      Issuers on the Notes pursuant to Section 2 hereof
      shall be 16.50% per annum for a period of 90 days, and shall

    
      
         
          

      

      
        28

        
          

        

      

      
         
          

      

    

     

    increase
      to 17.0% thereafter; provided, that if
      the
      interest rate on the Notes is 17.0% on the day prior to the Second Closing
      Date,
      such rate shall remain 17.0% until the earlier of the Effective Date and the
      date of repayment in full of the Notes.

     

    (e)           On
      and after the Effective Date, the rate of interest on the Notes shall be
      permanently readjusted to 16.0% per annum.

     

    (f)           The
      parties agree to execute supplements or amendments to the Indenture required
      to
      effect this Section
      8.1, if and when necessary.

     

    (g)           Notwithstanding
      the foregoing, this Section 8.1 shall be
      of no effect during any period that: (i) the reason that SkyTerra is unable
      to
      cause the Amendment to become effective is due to (x) SkyTerra’s inability to
      obtain required information from the Purchasers or Inmarsat plc in connection
      with SkyTerra’s filing of a proxy or information statement with the SEC, if
      and as required by law, or (y) SkyTerra’s inability to obtain required
      information from the Purchasers or Inmarsat plc in connection with the
      resolution of any comments or questions from the SEC with respect to such proxy
      or information statement; or (ii) SkyTerra effects a tax-free reorganization
      of
      its capital structure pursuant to Section 368(a)(1)(E) of the Code such that
      there are no shares of Non-Voting Common Stock outstanding subsequent to such
      reorganization.

     

    8.2           Exchange
      of Non-Voting
      Common Stock for Common Stock.

     

    (a)           To
      the extent any holder of a Warrant or its permitted assigns,
      obtains  shares of Non-Voting Common Stock issued upon exercise of a
      Warrant, SkyTerra will promptly upon the request of such holder or its permitted
      assign, exchange such shares of Non-Voting Common Stock for shares of Voting
      Common Stock on a one-for-one basis.  Upon surrender of certificates
      representing the shares of Non-Voting Common Stock that are being exchanged
      as
      part of such transfer, SkyTerra will issue to such Person certificates
      representing the appropriate number of shares of  Common
      Stock.  For the avoidance of doubt, other than as to voting and
      listing or quotation on a stock exchange, automatic quotation system or the
      OTC
      Bulletin Board, the Common Stock and Non-Voting Common Stock shall have
      identical rights and terms.

     

    (b)           Notwithstanding
      anything to the contrary contained in this Section 8.1, prior to
      the issuance of the Voting Common Stock, the holder of the Warrant or its
      permitted assigns shall have satisfied any and all legal or regulatory
      requirements for conversion, including compliance with the HSR Act, any
      applicable FCC requirements and any required shareholder approval as a result
      of
      a stock exchange where the Common Stock is then so listed or
      quoted.  SkyTerra shall use its reasonable best efforts in cooperating
      with such holder to obtain such legal or regulatory approvals to the extent
      its
      cooperation is necessary.  SkyTerra shall pay all necessary
      filing fees and reasonable out-of-pocket expenses to obtain such
      approvals.

     

    8.3           Reservation
      and
      Authorization of Common Stock; Registration with and Approval of Any
      Governmental Authority.  From and after the Original Issue
      Date, SkyTerra shall reserve and keep available for issuance upon and until
      the
      exercise of the Warrants such number of its authorized but unissued shares
      of
      Voting Common Stock as will be sufficient to permit the exchange in full of
      all
      shares of Non-Voting Common Stock issuable upon exercise in full of all
      outstanding Warrants less the number of shares of Voting

    
      
         
          

      

      
        29

        
          

        

      

      
         
          

      

    

     

    Common
      Stock that have previously been issued pursuant to Section
      8.2.  All shares of Voting Common Stock issuable pursuant to
      the terms hereof, when issued upon (i) exercise of the Warrants, or (ii)
      exchange of an equal number of shares of Non-Voting Common Stock in accordance
      with the terms hereof, shall be duly and validly issued and fully paid and
      nonassessable, not subject to preemptive rights and shall be free and clear
      of
      all Encumbrances.

     

    8.4           Legends.

     

    (a)           Each
      certificate for Common Stock initially issued upon the exercise of the Warrants
      (“Warrant
      Stock”), each certificate for Warrant Stock issued to any subsequent
      transferee of any such certificate, shall be stamped or otherwise imprinted
      with
      two legends in substantially the following forms:  “THE SHARES
      REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
      ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY
      STATE
      SECURITIES LAW.  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
      TRANSFERRED, SOLD, ASSIGNED, EXCHANGED, MORTGAGED, PLEDGED, HYPOTHECATED OR
      OTHERWISE DISPOSED OF OR ENCUMBERED WITHOUT COMPLIANCE WITH THE PROVISIONS
      OF,
      AND ARE OTHERWISE RESTRICTED BY THE PROVISIONS OF, THE ACT AND THE RULES AND
      REGULATIONS THEREUNDER.”  “THE SHARES REPRESENTED BY THIS CERTIFICATE
      ARE ENTITLED TO THE BENEFIT OF AND ARE SUBJECT TO CERTAIN OBLIGATIONS SET FORTH
      IN A CERTAIN WARRANT DATED __________, 2009, ORIGINALLY ISSUED BY SKYTERRA
      COMMUNICATIONS, INC. (THE “WARRANT”), PURSUANT
      TO THE EXERCISE OF WHICH SUCH SHARES WERE ISSUED.  A COPY OF THE
      WARRANT IS AVAILABLE AT THE EXECUTIVE OFFICES OF SKYTERRA COMMUNICATIONS,
      INC.”

     

    (b)           Each
      Warrant shall be stamped or otherwise imprinted with a legend in substantially
      the following form:  “NEITHER THIS WARRANT NOR ANY OF THE SECURITIES
      ISSUABLE UPON EXERCISE HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT
      OF
      1933, AS AMENDED (THE “ACT”), OR ANY
      STATE
      SECURITIES LAW.  THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE

      ENCUMBERED WITHOUT COMPLIANCE WITH THE PROVISIONS OF, AND ARE OTHERWISE
      RESTRICTED BY THE PROVISIONS OF, THE ACT, THE RULES AND REGULATIONS THEREUNDER
      AND THIS WARRANT.”

     

    (c)           Notwithstanding
      the foregoing provisions of this Section 8, the legend
      requirements of Section 8.4 shall
      terminate as to any particular Warrant or shares of Restricted Common Stock
      when
      SkyTerra shall have received from the holder thereof an opinion of counsel
      to
      the effect that such legend is not required in order to ensure compliance with
      the Securities Act.  Whenever the restrictions imposed by Section 8.4 shall
      terminate as to the Warrants, as hereinabove provided, the holder hereof shall
      be entitled to receive from SkyTerra, at the expense of SkyTerra, a new Warrant

    (d)           All
      Warrants issued upon registration of transfer, division or combination of,
      or in
      substitution for, any Warrant or Warrants entitled to bear such legend shall
      have a similar legend endorsed thereon.  Whenever the restrictions
      imposed by this Section shall terminate as to any share of Restricted Common
      Stock, as hereinabove provided, the holder thereof shall be entitled to receive
      from SkyTerra at SkyTerra’s expense, a new certificate representing such Common
      Stock not bearing the restrictive legend set forth in Section
      8.4(a).

     

    8.5           Publicity.  Except
      to the extent required by applicable laws, rules, regulations, stock exchange
      requirements or other obligations set forth in securities agreements outstanding
      as of the date hereof, neither the Issuers and SkyTerra, on the one hand, nor
      the Purchasers, on the other hand, shall, without the prior written consent
      of
      the other, make any public announcement or issue any press release with respect
      to the transactions and other matters contemplated by this
      Agreement.  The Purchasers agree that the Issuers and SkyTerra may
      issue a press release announcing the consummation of the sale of the Notes
      and
      Warrants in the form to be mutually agreed upon by the Issuers, SkyTerra and
      the
      Purchasers.

     

    8.6           Use
      of
      Proceeds.  The Issuers covenant and agree, and the Purchasers
      acknowledge, that the proceeds from the sale of the Notes, shall be used by
      the
      Issuers for lawful corporate purposes in accordance with the Issuers 2009
      business plan, as provided to the Purchasers prior to the execution of the
      MCSA.

     

    8.7           Right
      of Negotiation/Pro-rata
      Participation Right.

     

    (a)           If
      at any time prior to the earlier of (i) March 1, 2012, and (ii) such time that
      Purchasers and their Affiliates cease to collectively beneficially own at least
      five percent (5%) of the outstanding Common Stock, SkyTerra or any of its
      Subsidiaries proposes to issue any equity securities or options to purchase
      or
      rights to subscribe for any equity securities of SkyTerra or any of its
      Subsidiaries (other than Excluded Stock (as defined below)) (the “Offered Shares”)
      to any bona
      fide third party, SkyTerra or such Subsidiary shall first hold discussions
      with
      one representative for the Purchasers (the “Right of First
      Negotiation”) to determine whether a sale of all of the Offered Shares by
      SkyTerra (or any of its Subsidiaries) to any or all of the Purchasers is of
      interest to the Purchasers, and to determine whether agreement can be reached
      on
      terms reasonably satisfactory to the each of the parties. Upon a good faith
      determination by SkyTerra that such an agreement cannot be reached or if an
      agreement is not reached within five Business Days after the commencement of
      the
      Right of First Negotiation, SkyTerra may pursue a transaction with a bona fide
      third party involving the Offered Shares; provided, however,
      that to the extent
      any such transaction is consummated, the Purchasers shall have the pro-rata
      participation right set forth in Section 8.7(b)
      below.  Any sale of Offered Shares pursuant to this Section 8.7(a) shall
      be made within sixty (60) days after the commencement of the Right of First
      Negotiation.  From and after the sixty-first (61st)
      day after the commencement of the Right of First Negotiation, any sale of
      Offered Shares shall be subject to the provisions of this Section
      8.7(a).

     

    (b)           Following
      the completion or termination of the Right of First Negotiation, if SkyTerra
      or
      any of its Subsidiaries proposes to issue Offered Shares (other than Excluded
      Stock) to a bona fide third party, SkyTerra shall, no later than fifteen (15)
      days prior to the

    consummation
      of such transaction (a "Preemptive Rights
      Transaction"), give notice in writing (the "Preemptive
      Rights Offer
      Notice") to each Purchaser and to Harbinger Capital Partners Fund I, L.P.
      ( collectively the “Preemptive Rights
      Offerees”) of such Preemptive Rights Transaction.  The
      Preemptive Rights Offer Notice shall describe the proposed Preemptive Rights
      Transaction, and contain an offer (the "Preemptive Rights
      Offer") to sell to the Preemptive Rights Offerees, at the same price and
      for the same consideration to be paid by the proposed purchaser (provided,
      that,
      in the event any of such consideration is non-cash consideration, at the
      election of the Preemptive Rights Offeree to whom the Preemptive Rights Offer
      is
      made, such Preemptive Right Offeree may pay cash equal to the value of such
      non-cash consideration, determined in the manner as Fair Value is determined
      in
      the Warrant), all or any part of such Preemptive Right Offeree's pro rata
      portion of the Offered Shares (which shall be a fraction of the
      Offered Shares determined by dividing the number of shares of outstanding
      Common Stock owned by such Preemptive Right Offeree by the sum of (i) the number
      of shares of outstanding Common Stock owned by such Preemptive Right Offeree
      and
      (ii) the number of outstanding shares of Common Stock not held by such
      Preemptive Right Offeree).  If any Preemptive Right Offeree to whom a
      Preemptive Rights Offer is made fails to accept (a "Non-Responding
      Holder") in writing the Preemptive Rights Offer by the tenth (10th)
      day after SkyTerra's delivery of the Preemptive Rights Offer Notice, such
      Non-Responding Holder shall have no further rights with respect to the proposed
      Preemptive Rights Transaction. For purposes of this Section 8.6(b), each
      Preemptive Right Offeree's ownership of SkyTerra shall be deemed to include
      the
      number of shares of Common Stock equal to the product of: (i) the number of
      shares of common stock of the TerreStar Corporation (“TerreStar
      Corporation”) owned by such Preemptive Right Offeree divided by the total
      number of outstanding shares of the TerreStar Corporation outstanding on a
      fully-diluted basis; and (ii) the shares of Common Stock of SkyTerra held by
      TerreStar Corporation.  Additionally, notwithstanding the foregoing,
      no Preemptive Right Offeree shall be deemed to beneficially own another
      Preemptive Right Offeree's Common Stock.  Any sale of the Offered
      Shares pursuant to a Preemptive Rights Transaction shall be made within sixty
      (60) days after the delivery of the Preemptive Rights Offer
      Notice.  From and after the sixty-first (61st)
      day after the delivery of the Preemptive Rights Offer Notice, any sale of
      Offered Shares pursuant to this Section 8.7(b) shall
      be subject to a new Right of First Negotiation pursuant to Section
      8.7(a).

     

    (c)           "Excluded
      Stock" shall
      mean (i) options or similar convertible securities to employees, consultants,
      or
      directors, (ii) securities reserved for issuance to employees, directors,
      consultants or other service providers under arrangements, contracts or plans
      approved by the Board of Directors of SkyTerra, (iii) securities issued to
      any
      bank, licensor, equipment lessor or strategic partner, if and to the extent
      that
      the transaction in which such sale or grant is not principally for the purpose
      of raising equity capital, (iv) shares issued upon exercise of the
      Warrants, (v) securities upon exercise, exchange or conversion of convertible,
      exchangeable or exercisable securities issued as of the date hereof, (vi)
      securities issued in a Public Offering, (vii) securities issued in an
      acquisition transaction, (viii) securities issued in connection with any stock
      split, stock dividends or recapitalization, in all cases where shareholders
      are
      treated equally and ratably and (ix) securities issued by Mobile Satellite
      Ventures Holdings (Canada) Inc. and Mobile Satellite Ventures(Canada)
      Inc.

     

    (d)           Notwithstanding
      anything to the contrary contained herein, prior to the issuance to the
      Purchasers of any securities pursuant to the Right of First Negotiation or
      a

    
      
         
          

      

      
        32

        
          

        

      

      
         
          

      

    

    Preemptive
      Rights Offer or, in the event that securities to be issued are exercisable,
      convertible or exchangeable for Voting Common Stock, the Voting Common Stock
      issuable upon exercise, conversion or exchange of such securities, the
      Purchasers or its permitted assigns on the one hand, and SkyTerra on the other
      hand, shall have satisfied any and all applicable legal or regulatory or
      shareholder approval requirements (including the requirements of any stock
      exchange or automatic quotation system on which the Common Stock is then listed,
      traded or quoted) for issuance and/or conversion, including compliance with
      the
      HSR Act and FCC requirements.  SkyTerra shall use its reasonable best
      efforts in cooperating with the Purchasers to obtain such legal or regulatory
      approvals to the extent its cooperation is necessary.  SkyTerra shall
      pay all necessary filing fees and reasonable out-of-pocket expenses to obtain
      such legal or regulatory approvals.

     

    (e)           Notwithstanding
      anything to the contrary contained in this Section 8.7, no party
      to this Agreement shall have any rights pursuant to this Section 8.7 that
      are waived pursuant to Section 16.17 of the MCSA.

     

    8.8           Negative
      Covenants.  Prior to the earlier of (i) March 1, 2012, and (ii)
      such time that the Purchasers and their Affiliates cease to beneficially own
      at
      least 5% of the outstanding Common Stock, without the prior consent of the
      Purchasers;

     

    (a)           MSV
      shall not consolidate with or merge with or into, or convey, transfer or lease,
      in one transaction or a series of related transactions, directly or indirectly,
      all or substantially all of its assets to any Person (as defined in the
      Indenture) unless after immediately giving pro forma effect to such transaction,
      the Successor Person (as defined in the Indenture) would have a Consolidated
      Leverage Ratio (as defined in the Indenture) at least 10% better than
      immediately prior to the transaction.

     

    (b)           MSV
      shall not make any Restricted Payment (as defined in the Indenture) in violation
      of the Indenture, except for purposes of Section 4.08(a)(3)(A) of the Indenture,
      (i) 100% shall be replaced with 50%, and (ii) the deduction of 1.4 times the
      Consolidated Interest Expense (as defined in the Indenture) shall be
      deleted.

     

    8.9           Go-Shop
      Period.

     

    (a)           Notwithstanding
      any other provision of this Agreement to the contrary, during the period (the
      “Go-Shop
      Period”) beginning on the date hereof and continuing until 11:59 p.m.
      (EST) on the day prior to the First Closing Date, the Issuers, SkyTerra and
      their respective officers, directors, employees, consultants, agents, advisors,
      Affiliates and other representatives (“Representatives”)
      shall have the right to directly or indirectly:  (i) initiate, solicit
      and encourage Company Transaction Proposals (as hereinafter defined), including
      by way of providing access to non-public information pursuant to one or more
      customary confidentiality agreements and eliminating any existing standstill
      clause of which SkyTerra is a beneficiary, or any other burden or restriction
      that would prohibit or inhibit any Person actually or potentially interested
      in
      making an offer to SkyTerra from pursuing such offer; provided that the Issuers
      and SkyTerra shall promptly provide to each of the Purchasers any material
      non-public information concerning SkyTerra or any of its Subsidiaries that
      is provided to any Person given such access that was not previously provided
      to
      the Purchasers; and (ii) enter into and maintain discussions

    or
      negotiations with respect to Company Transaction Proposals or otherwise
      cooperate with or assist or participate in, or facilitate any such inquiries,
      proposals, discussions or negotiations.

     

    (b)           Notwithstanding
      any other provisions of this Agreement to the contrary, if, at any time prior
      to
      the First Closing Date, any Issuer or SkyTerra receives a Company Transaction
      Proposal which the Board of Directors of SkyTerra concludes in good faith
      constitutes a Superior Proposal, the Issuers and SkyTerra may terminate this
      Agreement prior to the First Closing Date in order to enter into a definitive
      agreement implementing such Superior Proposal.

     

    (c)           In
      case of termination of this Agreement under the terms of this Section 8.9, SkyTerra
      shall pay the Purchasers, and the Purchasers shall be entitled to receive from
      SkyTerra, upon completion of the funding of such Superior Proposal, notes
      convertible into shares of voting common stock of SkyTerra, the principal amount
      of which shall be equal to 1.5% of the amount issued or otherwise received
      by
      SkyTerra or any of its Subsidiaries in the transaction contemplated by the
      Superior Proposal.  The financial and certain other terms of such notes are
      set forth in Exhibit C hereto.  Such payment shall take place only
      upon the receipt by SkyTerra or such Subsidiaries of all or part of the funds,
      as result of the transaction contemplated by the Superior Proposal.

     

    (d)           In
      the event that the Purchasers terminate or breach their financing obligations
      under this Agreement, SkyTerra shall be entitled to seek alternative financing
      whether or not such financing is determined to be a Superior
      Proposal.

     

    (e)           As
      used in this Agreement, the terms:

     

    “Company
      Transaction Proposal” means any inquiry, proposal or offer from any Person or
      group of Persons other than the Purchasers or their respective Affiliates
      relating to any direct or indirect issuance by SkyTerra or any of its respective
      Subsidiaries, of any debt or equity securities or incurrence of other
      indebtedness with proceeds of such issuance or incurrence either singularly
      or
      in the aggregate exceeding U.S.$500,000,000 and in which the aggregate amount
      of
      shares of Common Stock being issued or Common Stock issuable through exercise
      of
      warrants does not exceed 20,000,000 shares and no other equity or convertible
      securities are issued; and

     

    “Superior
      Proposal” means a bona fide written Company Transaction Proposal that the Board
      of Directors of SkyTerra in good faith determines, would, if consummated, result
      in a transaction that is more favorable to SkyTerra and its existing
      stockholders than the transactions contemplated hereby, which determination
      is
      made, (x) after receiving the advice of a financial advisor (who shall be a
      nationally recognized investment banking firm), (y) after taking into account
      the likelihood (and likely timing) of consummation of such transaction on the
      terms set forth therein (as compared to the terms herein) and (z) after taking
      into account all appropriate legal (with the advice of outside counsel),
      financial (including the financing terms of any such proposal), regulatory
      or
      other aspects of such proposal and any other relevant factors permitted by
      applicable Law, including, without limitation, the likelihood that the Superior
      Proposal will satisfy applicable financial ratios and tests under SkyTerra’s
      existing indebtedness.

    (f)           Nothing
      contained in this Section 8.9 or
      elsewhere in this Agreement shall prohibit the Board of Directors of SkyTerra
      from complying with its disclosure obligations under U.S. federal or state
      Law
      with respect to a Company Transaction Proposal.

     

    8.10         Affirmative
      Covenants.  Prior to the earlier of (i) March 1, 2012, and (ii)
      such time that the Purchasers and their Affiliates cease to beneficially own
      at
      least 5% of the outstanding Common Stock, without the prior consent of the
      Purchasers:

     

    (a)           MSV
      will cause all properties used or useful in the conduct of its business or
      the
      business of any Significant Subsidiary to be maintained and kept in good
      condition, repair and working order and supplied with all necessary equipment
      and will cause to be made all necessary repairs, renewals, replacements,
      betterments and improvements thereof, all as in the judgment of MSV may be
      reasonably necessary so that the business carried on in connection therewith
      may
      be properly and advantageously conducted at all times; provided, however, that
      nothing in this Section 8.10(a) shall
      prevent MSV or any Significant Subsidiary from (i) discontinuing the use,
      operation or maintenance of any of such properties or disposing of any of them,
      if such discontinuance or disposal is, in the judgment of MSV, desirable in
      the
      conduct of its business or the business of any such Significant Subsidiary
      or
      (ii) effectuating an Asset Disposition (as defined in the Indenture) in
      accordance with the terms of the Indenture.

     

    (b)           MSV
      shall comply, and shall cause each of its Significant Subsidiaries to comply,
      with all applicable statutes, rules, regulations, orders and restrictions of
      the
      United States of America, all states and municipalities thereof, and of any
      governmental department, commission, board, regulatory authority, bureau, agency
      and instrumentality of the foregoing, in respect of the conduct of their
      respective businesses and the ownership of their respective properties, except
      for such noncompliances as are not in the aggregate reasonably likely to have
      a
      Material Adverse Effect.

     

    8.11         Cooperation.  The
      parties hereto shall cooperate in good faith and make all reasonable necessary,
      proper or advisable efforts to determine whether any facts or circumstances
      that
      could give rise to a Material Adverse Effect exist.  Cooperation under
      this Section shall not be deemed to be, or be construed, as a waiver of any
      right, term or provision under this Agreement and shall not create any type
      of
      estoppel whatsoever, on the cooperating party, from exercising in full its
      rights under this Agreement.

     

    9.           Miscellaneous
      Provisions.

     

    9.1           Rights
      Cumulative.  Each and all of the various rights, powers and
      remedies of the parties shall be considered to be cumulative with and in
      addition to any other rights, powers and remedies which such parties may have
      at
      law or in equity in the event of the breach of any of the terms of this
      Agreement.  The exercise or partial exercise of any right, power or
      remedy shall neither constitute the exclusive election thereof nor the waiver
      of
      any other right, power or remedy available to such party.

     

    9.2           Pronouns.  All
      pronouns or any variation thereof shall be deemed to refer to the masculine,
      feminine or neuter, singular or plural, as the identity of the Person, Persons,
      entity or entities may require.

    9.7           Waiver.  No
      waiver of any term, provision or condition of this Agreement, whether by conduct
      or otherwise, in any one or more instances, shall be deemed to be, or be

      condition or as a waiver of any other term, provision or condition of this
      Agreement.

     

    9.8           Assignment.  The
      rights and obligations of any party hereto shall inure to the benefit of and
      shall be binding upon the authorized successors and permitted assigns of such
      party. None of  the Issuers, SkyTerra or the Purchasers may assign
      this Agreement or any rights or obligations hereunder without the prior written
      consent of the other; provided, however, that the
      each of Purchasers may assign this Agreement in whole or in part to one or
      more
      Affiliates of the Purchasers, whether presently existing or hereinafter created
      by providing notice in writing to the Issuers and SkyTerra.

     

    9.9           Survival.  The
      respective representations and warranties given by the parties hereto shall
      survive each Closing Date and the consummation of the transactions contemplated
      herein and shall expire on the date that is eighteen (18) months after such
      Closing Date (the “Survival Period”).
      Accordingly, no claim relating to any representation or warranty given by the
      parties hereto applicable to each Survival Period, may be made following such
      expiration.  If a claim relating to any representation or warranty
      given by the parties hereto is made on or prior to the expiration thereof,
      then,
      notwithstanding anything to the contrary contained in this Section 9.9, such
      representation or warranty shall not so expire, but rather shall remain in
      full
      force and effect until such time as such claim has been fully and finally
      resolved, either by means of a written settlement agreement executed on behalf
      of the parties or by means of a final, non-appealable judgment issued by a
      court
      of competent jurisdiction.   The respective covenants and
      agreements agreed to by a party hereto shall survive the last Closing
      Date unless otherwise specified.

     

    9.10         Entire
      Agreement.  This Agreement and the other Transaction Documents
      constitute the entire agreement among the parties hereto respecting the subject
      matter hereof and supersede all prior agreements, negotiations, understandings,
      representations and statements respecting the subject matter hereof, whether
      written or oral, among the Issuers and the Purchasers.

     

    9.11         Amendments.  Any
      amendment, supplement or modification of or to any provision of this Agreement
      and any waiver of any provisions of this Agreement shall be effective only
      if
      made or given in writing and signed by the Issuers and the
      Purchasers.

     

    9.12         No
      Third Party
      Rights.  This Agreement is intended solely for the benefit of
      the parties hereto and their respective successors and permitted assigns and
      is
      not intended to confer any benefits upon, or create any rights in favor of,
      any
      Person (including, without limitation, any stockholder or debt holder of the
      Issuers or SkyTerra) other than the parties hereto.

     

    9.13         Counterparts.  This
      Agreement may be executed in any number of counterparts, each of which shall
      be
      deemed an original, but all of which together shall constitute one and the
      same
      document. The parties hereto confirm that any facsimile copy of

    another
      party’s executed counterpart of this Agreement (or its signature page thereof)
      will be deemed to be an executed original thereof.

     

    9.14         Expenses.  Whether
      or not the transactions contemplated by the Transaction Documents are
      consummated, the Issuers shall pay all reasonable, documented fees and expenses
      incurred by the Purchasers in connection with the negotiation, preparation
      and
      execution of the Transaction Documents and the consummation of the
      transactions contemplated hereby.

        that for the purposes of determining whether the Trustee shall be protected

        Officer of the Trustee actually knows are so owned shall be so
        disregarded.  Notes so owned which have been pledged in good faith
        shall not be disregarded if the pledgee establishes to the satisfaction of
        the
        Trustee the pledgee’s right so to act with respect to the Notes and that the
        pledgee is not an Issuer, a Guarantor or any other obligor upon the Notes
        or any
        Affiliate of any of them."
