(b) If an Indemnified Party receives notice from any third party with respect to, or otherwise becomes aware of, an Indemnifiable Claim, then the Indemnified Party shall promptly (but in any event no later than 5 days after receipt of such notice) notify TerreStar thereof in writing; provided, however, that no delay on the part of the Indemnified Party in so notifying TerreStar shall relieve TerreStar from any obligation under this Article VI unless (and then solely to the extent that) TerreStar is thereby prejudiced.

(d) TerreStar will not, without the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld), consent to the entry of judgment or enter into any settlement or compromise in respect of which indemnification has been sought hereunder, unless such settlement or compromise includes an unconditional release of the Indemnified Party and each controlling person thereof from all liability arising out the Indemnifiable Claim.

Attention: General Counsel

Gentlemen:

Reference is made to that certain Stock Purchase Agreement (the “Harbinger Purchase Agreement”), dated as of September 12, 2008, by and among Harbinger Capital Partners Master Fund I, Ltd.

(the “Company”).

Reference is also made to that certain Letter Agreement (the "Initial Letter Agreement"), dated as of September 12, 2008, by and among Harbinger and the Company, pursuant to which the Company (i) agreed to exchange the Purchased Shares for shares of Voting Common Stock (as hereinafter defined), (ii) agreed to amend the Registration Rights Agreements (as hereinafter defined) to include the Purchased Shares in the definition of 'Registrable Shares', and (iii) consented to the purchase of the Purchased Shares by Harbinger pursuant to the Harbinger Purchase Agreement.

Reference is also made to that certain Registration Rights Agreement (the “Registration Rights Agreement”), dated as of July 24, 2008 and as may be amended from time to time, by and among Harbinger Master, Harbinger Special, Harbinger Co-Investment Fund, L.P. (“Satellite Fund”), Harbinger Capital Partners Fund I, L.P. (“Capital Fund” and, collectively with Harbinger and Satellite Fund, the “Securityholders”) and the Company, pursuant to which the Company has granted the Securityholders certain registration rights with respect to certain securities issued or to be issued by the Company.

Further reference is made to that certain Exchange Agreement (the “Exchange Agreement”), dated as of May 6, 2006, by and among TerreStar Corporation (f/k/a Motient Corporation) (“TerreStar”), Motient and the Company pursuant to which the Company purchased from Motient 9,034,848.51 limited partnership units of Mobile Satellite Ventures, LP (“MSV”) and 1,572.11 shares of common stock of Mobile Satellite Ventures GP, Inc. in exchange for 25,478,273 shares of the Company’s Non-Voting Common Stock exchangeable in

C-2

certain circumstances for an equal number of shares of the Company’s Voting Common Stock (as defined below).

1. Other Shares. Pursuant to Section 2.6 of the Harbinger Purchase Agreement, Harbinger has agreed to purchase from Motient an additional 250,000 shares (the "Additional Shares") of Non-Voting Common Stock. Such Additional Shares shall be held in escrow by the Collateral Agent (as hereinafter defined) for the benefit of Harbinger, pending receipt of the FCC Consent (as hereinafter defined). None of the Additional Shares are being exchanged for shares of Voting Common Stock on the date hereto.

Exchange of Shares.

(a) At any time and from time to time after the date of this Letter Agreement, at the request of Harbinger or any Affiliate of Harbinger (each a "Harbinger Affiliate" and collectively with Harbinger, each a "Stockholder"), upon the certification of Harbinger or such Harbinger Affiliate to SkyTerra of the representation and warranty contained in Section 4(c) with respect to such entity as of such date, the Company will exchange all or part of the Additional Shares for shares of the Company's voting common stock, par value $0.01 per share (the "Voting Common Stock", and together with the Non-Voting Common Stock , the "Common Stock") on a one-for-one basis (in each case as appropriately adjusted for any stock split, combination, capital reorganization, reclassification, stock dividend, stock distribution or similar event declared or effected after the date hereof) (the "Exchanged Shares").

In the event that Harbinger is unable to obtain the consent of the Federal Communications Commission ("FCC") authorizing Harbinger to own up to 100% of the Common Stock of the Company (the "FCC Consent"), which is required in order for Harbinger to take title to the Additional Shares, and the Collateral Agent (as hereinafter defined) in possession of such Additional Shares sells some or all of the Additional Shares to a third party (such third party, also a "Stockholder"), then the Company agrees that at any time and from time to time, at the request of such third party, the Company will exchange all or part of such Additional Shares for shares of Voting Common Stock on a one-for-one basis (in each case as appropriately adjusted for any stock split, combination, capital reorganization, reclassification, stock dividend, stock distribution or similar event declared or effected after the date hereof) provided that such third party provides to SkyTerra a certification of the representations and warranties contained in Section 4 with respect to such third party as of such date. Upon surrender of certificates representing the shares of Non-Voting Common Stock that are being exchanged, the Company will issue to such Stockholder certificates representing the appropriate number of shares of Voting Common Stock registered in the name of such Stockholder or such other Person as the Stockholder may designate. The shares of Voting Common Stock issuable upon exchange for the shares of Non-Voting Common Stock will have been duly authorized by the Company and, when delivered in accordance with the terms of this Letter Agreement and upon surrender of the Additional Shares to the Company, will be validly issued, fully paid and nonassessable.

C-3

For the purposes of this Letter Agreement, "Collateral Agent" shall mean Goldberg, Godles, Wiener & Xxxxxx .

(b) The certificates representing the Voting Common Stock issued pursuant to Section 1(a) will bear the following legend:

“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, (II) SUCH TRANSACTION IS PURSUANT TO RULE 144, RULE 144A OR REGULATION S UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (III) AN OPINION OF COUNSEL, WHICH OPINION IS REASONABLY SATISFACTORY TO THE ISSUER, HAS BEEN DELIVERED TO THE ISSUER AND SUCH OPINION STATES THAT THE SECURITIES MAY BE TRANSFERRED WITHOUT SUCH REGISTRATION.”

(c) If the issuance of shares of Voting Common Stock to any Stockholder pursuant to Section 1(a) would conflict with, violate or constitute a breach or default under FCC rules or regulations to which the Company or any of its subsidiaries is subject; violate any judgment, order, decree or law applicable to the Company or any of its subsidiaries; or delay or otherwise adversely impact any consent, approval, or filing of the Company or its subsidiaries with the FCC, then the Company shall issue the maximum number of shares of Voting Common Stock pursuant to Section 1(a) that can be issued without causing such conflict, violation, breach, delay or adverse impact, or without receipt of such consent or approval, or pursuant to such consent or approval.

3. Registration Rights Agreement. As promptly as reasonably practicable, the Company and Harbinger shall take all actions necessary to amend the definition of “Registrable Shares” in the Registration Rights Agreement to include the Additional Shares to be purchased by Harbinger pursuant to the Harbinger Purchase Agreement. In the event that Harbinger is unable to obtain the FCC Consent, and the Collateral Agent sells some or all of the Additional Shares to a third party, the Company agrees, as promptly as reasonably practicable following such sale, to take all actions necessary to enter into a customary registration rights agreement with such third party, providing for a shelf resale registration statement with respect to such Additional Shares. Such agreement shall be in substantially the form of the registration rights agreement being entered into by the Company with investors purchasing an aggregate of 6,300,000 shares of the Company’s common stock from Motient pursuant to the Letter Agreements dated the date hereof (the “Other Investors Letter Agreement”), and such registration rights shall not obligate the Company to consummate or assist in any underwritten offering.

C-4

4. Company Consent. The Company hereby agrees and consents in all respects to the sale of the Additional Shares to Harbinger pursuant to the terms and conditions of the Harbinger Purchase Agreement as such agreement is in effect on the date hereof.

5. Harbinger Representations and Warranties. Harbinger hereby represents and warrants to the Company as follows:

(c) Government Approvals.

ARTICLE XIII.

REGISTRATION OF THE TERRESTAR SHARES

Section 13.1

Registration Request.

(a) From the later of the Closing Date and May 15, 2009, and until May 15, 2014, if requested in writing by one or more Investors, including Holder, with respect to, in the aggregate, not less than 4.37 million Investors Shares (as appropriately adjusted for any stock split, combination, reorganization, recapitalization, reclassification, stock dividend, stock distribution or similar event declared or effected with respect to the TerreStar Shares or the Networks Shares) (such request, a “Registration Request” and the date thereof, the “Request Date”), which shall include a completed Notice and Questionnaire, TerreStar shall as promptly as practicable but in any event no later than the 30^th day after the Request Date file with the SEC a shelf registration statement (the “Shelf Registration Statement”) providing for the registration of, and the sale on a continuous or delayed basis by Holder of, the Registrable Shares to which the Registration Request relates, pursuant to Rule 415 under the Securities Act or any similar rule that may be adopted by the SEC. TerreStar shall use commercially reasonable efforts to cause the Shelf Registration Statement to become or be declared effective under the Securities Act as promptly as practicable but in no event later than 90 days after the Request Date and to keep the Shelf Registration Statement continuously effective until the earlier of (i) the time when all TerreStar Shares included on such Shelf Registration Statement are no longer Registrable Shares and (ii) the time when a Registration Statement has been in effect with respect to the Registrable Shares for periods totaling 1 year, not counting toward such year (A) any periods when a Deferral Notice is in effect or (B) any Registration Break (such date, the “Registration End Date”). Commercially reasonable efforts shall be deemed to have been used notwithstanding an inability to have the Shelf Registration Statement declared or kept effective due to an inability to obtain the consent of TerreStar’s accountants if TerreStar acts in good faith and after the use of commercially reasonable efforts to obtain such consent by TerreStar.

(b) TerreStar may, at its option, decline to make available a Shelf Registration Statement during the period starting on any Other Registration End Date and ending on the earlier of (i) 3 months following such Other Registration End Date and (ii) the date when TerreStar shall file with the SEC any registration statement with respect to any of its securities (such a period, a “Registration Break”). If the 30- or 90-day period following the Request Date referred to in Section 6.1(a) expires during a Registration Break, TerreStar’s applicable obligation under Section 6.1(a) following the end of such 30- or 90-day period shall commence immediately upon the end of the Registration Break; any period of time that has elapsed between a Request Date and the start of such Registration Break shall count toward the 30- or 90-day

D-11

period referred to in Section 6.1(a). If a Registration Statement became effective and then ceased to be effective due to a Registration Break, TerreStar shall be obligated to use commercially reasonable efforts cause the applicable Registration Statement to become or be declared effective under the Securities Act by the end of the Registration Break.

(c) TerreStar shall cause the Shelf Registration Statement and the related Prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement or such amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act; and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and TerreStar shall furnish to Holder copies of any supplement or amendment upon the request of Holder prior to its being used or promptly following its filing with the SEC; provided, however, that TerreStar shall have no obligation to deliver to Holder copies of any amendment consisting exclusively of an Exchange Act report or other Exchange Act filing otherwise publicly available on TerreStar’s website (except in such instances in which TerreStar is correcting a material misstatement in any Registration Statement or Prospectus with respect to Holder’s shares of TerreStar Common Stock pursuant to Sections 6.2(a)(iv) and (ix)). If the Shelf Registration Statement, as amended or supplemented from time to time, ceases to be effective for any reason prior to the Registration End Date, TerreStar shall use commercially reasonable efforts, subject to Section 6.2(b), to obtain the prompt withdrawal of any order suspending the effectiveness thereof.

(d) In the event that the SEC requires TerreStar, or counsel for TerreStar in good faith (after consultation with the SEC) advises that the SEC would require TerreStar, to reduce the amount of TerreStar securities to be included in a Shelf Registration Statement in order to allow TerreStar to have such sales be treated as secondary sales with respect to such Shelf Registration Statement so that not all Investors Shares and other TerreStar securities entitled by binding agreements in effect on September 12, 2008 to be included in such Shelf Registration Statement may be so included, then, if Holder consents in writing to be named as an “underwriter” in such Shelf Registration Statement, TerreStar shall be obligated to include in such Shelf Registration Statement any Registrable Shares requested to be included therein by Holder, and comply with the requirements of Section 6.1(e); if Holder does not consent in writing to be named as an “underwriter” in such Shelf Registration Statement, then, TerreStar shall be obligated to include in such Shelf Registration Statement (which may be a subsequent Registration Statement if TerreStar needs to withdraw the initial Registration Statement and re-file a new Registration Statement in order to rely on Rule 415 under the Securities Act and have such sales be treated as secondary sales) only such limited portion of the securities otherwise entitled to be included in the Shelf Registration Statement as the SEC shall or would permit. Any Registrable Shares that are excluded in accordance with the foregoing terms are hereinafter referred to as “Cut Back Securities.” In the event there are Cut Back Securities, the right to be included in the Registration Statement shall be allocated first, to any persons entitled to register securities pursuant to Prior Registration Agreements, and second, among the Investors, pro rata based on the percentage of such securities requested to be included therein or as TerreStar and the Investors may otherwise agree. To the extent Cut Back Securities exist, at the option of the Investors, TerreStar shall use commercially reasonable efforts to take one or more of the following actions: (i) re-file such Shelf Registration Statement on Form S-1 in order to register

D-12

any Cut Back Securities (and withdraw the initially filed Shelf Registration Statement or amend it, as required) if such re-filing will permit TerreStar to rely on Rule 415 under the Securities Act and have such sales be treated as secondary sales with respect to such Shelf Registration Statement; (ii) conduct one additional Underwritten Offering in addition to that provided for in Section 6.2(h) for all Investors who wish to participate therein on the terms set forth in Section 6.2(h); and (iii) register the Cut Back Securities in accordance with the provisions of this Section 6.1 and Section 6.2 promptly when eligible to do so under applicable federal securities Law, subject to the allocation set forth above, as TerreStar and its securities counsel reasonably determine (in consultation with the Investors and their securities counsel), in each case, unless the Cut Back Securities cease to be Registrable Shares.

(e) If Holder elects to be named as an “underwriter” in any Shelf Registration Statement pursuant to Section 6.1(c), then TerreStar shall:

(i) cooperate with any reasonable due diligence investigation undertaken by Holder, Holder’s counsel and any attorney, accountant or other agent retained by Holder in connection with the filing of the Shelf Registration Statement and the sale of Registrable Shares thereunder, including making available any documents and information reasonably requested by Holder and its Representatives and making available members of TerreStar’s senior management for discussions with Holder;

(ii) make available for inspection by Holder, and any attorney, accountant or other agent retained by such Holder (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of TerreStar and any of its subsidiaries (collectively, the “Records”) as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the officers, directors and employees of TerreStar to supply all information reasonably requested by any such Inspector in connection with any registration hereunder, provided, however, that (i) in connection with any such inspection, any such Inspectors shall cooperate to the extent reasonably practicable to minimize any disruption to the operation by TerreStar of its business, and (ii) Records and information obtained hereunder shall be used by such Inspectors only to exercise their due diligence responsibility; and

(iii) use commercially reasonable efforts to furnish to Holder a signed counterpart, addressed to such Holder of (i) an opinion or opinions of counsel to TerreStar and (ii) a comfort letter or comfort letters from TerreStar’s independent public accountants pursuant to Statement on Auditing Standards No. 72, each in customary form and covering such matters of the type customarily covered by opinions or comfort letters, as the case may be, as each such Holder and the managing underwriter, if any, reasonably requests.

(iii) use commercially reasonable efforts to prepare and file with the SEC such amendments and post-effective amendments to the Shelf Registration Statement and file with the SEC any other required document as may be necessary to keep the Shelf Registration Statement continuously effective until the Registration End Date; cause the related Prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act; and comply with the provisions of the Securities Act applicable to it with respect to the disposition of all Registrable Shares covered by the Shelf Registration Statement in accordance with the intended methods of disposition by Holder set forth in the Shelf Registration Statement as so amended or such Prospectus as so supplemented;

(iv) promptly notify Holder (A) when the Shelf Registration Statement or the Prospectus included therein or any amendment or supplement to the Prospectus or post-effective amendment has been filed with the SEC, and, with respect to the Shelf Registration Statement or any post-effective amendment, when the same has become effective, (B) of any request, following the effectiveness of the Shelf Registration Statement, by the SEC or any other Governmental Authority for amendments or supplements to the Shelf Registration Statement or related Prospectus, (C) of the issuance by the SEC of any stop order suspending the effectiveness of the Shelf Registration Statement or the initiation or written threat of any proceedings for that purpose, (D) of the receipt by TerreStar of any notification with respect to the suspension of the qualification of the Registrable Shares for sale in any jurisdiction or the initiation or written threat of any proceeding for such purpose, (E) of the occurrence of (but not the nature of or details concerning) any event or the existence of any fact (a “Material Event”) as a result of which the Shelf Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or any Prospectus shall contain any untrue

D-14

statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, (F) of the determination by TerreStar that a post-effective amendment to the Shelf Registration Statement will be filed with the SEC, which notice may, at the discretion of TerreStar (or as required pursuant to Section 6.2(b)), state that it constitutes a Deferral Notice, in which event the provisions of Section 6.2(b) shall apply or (G) at any time when a Prospectus is required to be delivered under the Securities Act, that the Shelf Registration Statement, Prospectus, Prospectus amendment or supplement or post-effective amendment does not conform in all material respects to the applicable requirements of the Securities Act and the rules and regulations of the SEC thereunder;

(v) use commercially reasonable efforts to register or qualify, or cooperate with Holder and its counsel in connection with the registration or qualification of, such Registrable Shares for offer and sale under the securities or blue sky Laws of such jurisdictions as Holder reasonably requests in writing, to the extent required by Law, and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of such Registrable Shares; prior to any public offering of the Registrable Shares pursuant to the Shelf Registration Statement, subject to Section 6.2(b), use commercially reasonable efforts to keep each such registration or qualification (or exemption therefrom) effective until the Registration End Date in connection with Holder’s offer and sale of Registrable Shares pursuant to such registration or qualification (or exemption therefrom) and do any and all other acts or things reasonably necessary or advisable to enable the disposition in such jurisdictions of such Registrable Shares in the manner set forth in the Shelf Registration Statement and the related Prospectus, to the extent required by Law; provided, that TerreStar will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process or to taxation in any such jurisdiction where it is not then so subject;

(vi) use commercially reasonable efforts to prevent the issuance of, and if issued, to obtain the withdrawal of any order suspending the effectiveness of the Shelf Registration Statement or any post-effective amendment thereto, and to lift any suspension of the qualification of Registrable Shares for sale in any jurisdiction in which they have been qualified for sale, in each case at the earliest practicable date;

(vii) if reasonably requested by Holder, promptly incorporate in a prospectus supplement or post-effective amendment to the Shelf Registration Statement such information that Holder shall, on the basis of advice of nationally-recognized counsel experienced in such matters, determine to be required to be included therein by applicable Law and make any required filings of such prospectus supplement or such post-effective amendment; provided, that TerreStar shall not be required to take any actions under this Section 6.2(a)(vii) that are not, in the reasonable advice of nationally-recognized counsel for TerreStar experienced in such matters, in compliance with applicable Law;

D-15

(viii) promptly furnish to Holder, upon its request and without charge, at least 1 conformed copy of the Shelf Registration Statement and any amendments thereto, including financial statements but excluding schedules, all documents incorporated or deemed to be incorporated therein by reference and all exhibits; provided, however, that TerreStar shall have no obligation to deliver to Holder a copy of any amendment consisting exclusively of an Exchange Act report or other Exchange Act filing otherwise publicly available on TerreStar’s website;

(x) cooperate with Holder to facilitate the timely preparation and delivery of certificates representing Registrable Shares to be sold pursuant to the Shelf Registration Statement free of any restrictive legends and in such denominations and registered in such names as Holder may request in writing at least two business days prior to sales of Registrable Shares pursuant to the Shelf Registration Statement.

(b) Upon (A) the issuance by the SEC of a stop order suspending the effectiveness of the Shelf Registration Statement or the initiation of proceedings with respect to the Shelf Registration Statement under section 8(d) or 8(e) of the Securities Act, (B) the occurrence of any event or the existence of any Material Event as a result of which the Shelf Registration Statement shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, or any Prospectus shall contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (C) a determination by TerreStar’s Board of Directors that, prior to the effective date of any Shelf Registration Statement, effecting the registration would adversely affect an offering of securities of TerreStar the preparation of which has then been commenced, or that TerreStar is in possession of material non-public information the disclosure of which would not be in the best interest of TerreStar, TerreStar will give notice to Holder that the availability of the Shelf Registration Statement is suspended for a period not to exceed 45 days (a “Deferral Notice”). Upon receipt of any Deferral Notice, Holder shall not sell any Registrable Shares pursuant to the Shelf Registration Statement until Holder’s receipt of copies of the supplemented or amended Prospectus provided for in clause (i) above, or until it is advised in writing by TerreStar that the Prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus. TerreStar will use commercially reasonable efforts to ensure that the use of the Prospectus may be resumed (x) in the case of clause (A) above, as promptly as practicable, (y) in the case of clause (B) above, as

D-16

soon as, in the sole judgment of TerreStar, public disclosure of such Material Event would not be prejudicial to or contrary to the interests of TerreStar or, if necessary to avoid unreasonable burden or expense, as soon as practicable thereafter and (z) in the case of clause (C) above, as soon as, in the discretion of TerreStar, such suspension is no longer appropriate. TerreStar shall not issue in excess of 2 Deferral Notices in any 365 day period, and shall not issue any Deferral Notice within 60 days of any other Deferral Notice.

(c) Upon receipt of a Deferral Notice, Holder shall forthwith discontinue (and cause any placement or sales agent or underwriters acting on its behalf to discontinue) the disposition of Registrable Shares pursuant to the Shelf Registration Statement until Holder (i) shall have received copies of such amended or supplemented Prospectus and, if so directed by TerreStar, Holder shall deliver to TerreStar all copies, other than permanent file copies, then in Holder’s possession of the Prospectus covering such Registrable Shares at the time of receipt of such notice or (ii) shall have received notice from TerreStar that the disposition of Registrable Shares pursuant to the Shelf Registration Statement may continue.

(d) TerreStar may require Holder to furnish to TerreStar such information regarding Holder and its intended method of distribution of such Registrable Shares as TerreStar may from time to time reasonably request in writing, but only to the extent that such information is required in order to comply with the Securities Act or other applicable Law. Holder shall notify TerreStar as promptly as practicable of any inaccuracy or change in information previously furnished by Holder to TerreStar or of the occurrence of any event in either case as a result of which any Prospectus relating to such registration contains or would contain an untrue statement of a material fact regarding Holder or Holder’s intended method of disposition of such Registrable Shares or omits to state any material fact regarding Holder or Holder’s intended method of disposition of such Registrable Shares required to be stated therein or necessary to make the statements therein not misleading, and promptly to furnish to TerreStar any additional information required to correct and update any previously furnished information or required so that such Prospectus shall not contain, with respect to Holder or the disposition of such Registrable Shares, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(e) TerreStar shall comply with all applicable rules and regulations of the SEC and make generally available to its securityholders earning statements satisfying the provisions of section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the Securities Act) no later than (i) 40 days after the end of any 12-month period (or 60 days after the end of any 12-month period if such period is a fiscal year) if TerreStar is at such time an “accelerated filer” and (ii) 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year) if TerreStar is not an “accelerated filer” commencing on the first day of the first fiscal quarter of TerreStar commencing after the effective date of the Shelf Registration Statement, which statements shall cover said 12-month periods.

(f) TerreStar shall use commercially reasonable efforts to provide such information as is required for any filings required to be made with FINRA.

D-17

(g) TerreStar shall enter into customary agreements and use commercially reasonable efforts to take all other necessary and lawful actions in connection therewith in order to expedite or facilitate disposition of the Registrable Shares.

(h) If requested by Investors holding more than one-third of the then-outstanding Investors Shares, there shall be a single Underwritten Offering (for this Agreement and all Other Agreements together) for all Investors who wish to participate therein, apart from the one additional Underwritten Offering provided for in Section 6.1(d). The Underwritten Offering may be effected as a take-down off of any Shelf Registration Statement or, if unavailable, pursuant to the filing by TerreStar of a new Registration Statement or the combination of one or more Shelf Registration Statements. The Investor or Investors requesting the Underwritten Offering shall have the right to select the managing underwriter(s) to administer the Underwritten Offering, subject to the prior approval of TerreStar, which approval shall not be unreasonably withheld, conditioned or delayed. TerreStar agrees to enter into such agreements (including underwriting agreements in customary form), and take all such other actions as the Investor or the underwriter(s) reasonably request in order to expedite or facilitate the Underwritten Offering (including causing senior management and other Company personnel to cooperate with the Investors and the underwriter(s) in connection with performing due diligence). TerreStar shall pay for all Registration Expenses incident to such Underwritten Offering pursuant to Section 6.6, but not including any underwriting discounts or commissions incurred by the Investors in such Underwritten Offering. In the event there is a second Underwritten Offering pursuant to Section 6.1(d), or if an attempted Underwritten Offering is not counted as a result of the last sentence of the definition of such term, TerreStar shall not be obligated to permit the second or replacement Underwritten Offering until 9 months following the completion of the first or attempted Underwritten Offering.

Section 13.3

Piggyback Registration.

(a) If, on any Nonregistration Day or during a Registration Break or any period during which a Deferral Notice is in effect, TerreStar desires to file any registration statement under the Securities Act for purposes of effecting an underwritten (i) primary public offering by TerreStar or (ii) public offering by another holder of TerreStar Common Stock (excluding, in each case, registration statements relating to any employee benefit plan or a corporate reorganization or other transaction covered by Rule 145 promulgated under the Securities Act, or a registration on any registration form which does not permit secondary sales), or providing for the registration of, and the sale on a continuous or delayed basis TerreStar Common Stock pursuant to Rule 415 under the Securities Act or any similar rule that may be adopted by the SEC, by TerreStar or another holder of TerreStar Common Stock (each, a “Piggyback Registration Statement”), TerreStar will provide at least 15 days prior notice to Holder and SkyTerra and will afford Holder an opportunity to include in such registration statement all or any part of the Registrable Shares. If Holder desires to include in any such registration statement all or any part of the Registrable Shares, Holder shall, within 10 days after receipt of such notice, so notify TerreStar, and in such notice shall inform TerreStar of the number of Registrable Shares such Holder wishes to include in such registration statement. If Holder decides not to include all of its Registrable Shares in any such registration statement thereafter filed by TerreStar, Holder shall nevertheless continue to have the right to include any Registrable Shares in any subsequent registration statement or registration statements as may be

D-18

filed by TerreStar with respect to such offerings of its securities, all upon the terms and conditions set forth herein.

(b) In the event that the SEC requires TerreStar, or counsel for TerreStar in good faith (after consultation with the SEC) advises that the SEC would require TerreStar to reduce the amount of TerreStar securities to be included in a Piggyback Registration Statement in order to allow TerreStar to rely on Rule 415 under the Securities Act and have such sales be treated as secondary sales with respect to such registration statement, then, if Holder consents in writing to be named as an “underwriter” in such registration statement, TerreStar shall be obligated to include in such registration statement any Registrable Shares requested to be included therein by Holder, and comply with the requirements of Section 6.1(e) (it being understood that TerreStar shall not be obligated to delay the securities offering pursuant to the Piggyback Registration Statement in order to permit the completion of the activities referred to in such Section); if Holder does not consent in writing to be named as an “underwriter” in such registration statement, then TerreStar shall be obligated to include in such registration statement (which may be a subsequent Registration Statement if TerreStar needs to withdraw the initial Registration Statement and re-file a new Registration Statement in order to rely on Rule 415 under the Securities Act and have such sales be treated as secondary sales) only such limited portion of the securities otherwise entitled to be included therein as the SEC shall or, based on the advice of TerreStar’s counsel, would permit. Any Registrable Shares that are excluded in accordance with the foregoing terms are hereinafter referred to as “Piggyback Cut Back Securities.” In the event there are Piggyback Cut Back Securities, the right to be included in the Registration Statement shall be allocated first, to the parties entitled to request that such registration statement be filed and any persons entitled to register securities pursuant to Prior Registration Agreements, and second, to the Investors, pro rata based on the percentage of such securities owned by them and requested to be included therein (or as may otherwise be agreed by TerreStar and the Investors).

(c) In the event TerreStar gives notice under this Section 6.3, the right of Holder to include Registrable Shares to be included in a registration statement pursuant to this Section 6.3, if it is an underwritten offering, shall be conditioned upon Holder’s participation in such underwriting and the inclusion of the Registrable Shares in the underwriting to the extent provided herein. If Holder proposes to distribute Registrable Shares through such underwriting, it shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Agreement, if the managing underwriters determine in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriters may exclude shares (including Registrable Shares) from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first, to TerreStar and any persons entitled to register securities pursuant to Prior Registration Agreements and second, to Holder and other Investors on a pro rata basis (or as otherwise agreed by the Investors and TerreStar). If Holder disapproves of the terms of any such underwriting, Holder may elect to withdraw therefrom by notice to TerreStar and the underwriter, delivered at least 10 days prior to the effective date of the registration statement; provided, however, such 10-day deadline shall not apply if at the time of such withdrawal, Holder has learned of a material adverse change in the condition, business or prospects of TerreStar not known to Holder at the time of its request for such registration and has withdrawn

D-19

its request for registration with reasonable promptness after learning of such material adverse change. Any Registrable Shares excluded or withdrawn from such underwriting shall be excluded and withdrawn from the registration.

Section 13.4 Holder’s Obligations. Holder shall not be entitled to sell any Registrable Shares pursuant to a Registration Statement or to receive a Prospectus relating thereto unless Holder has furnished TerreStar with a Notice and Questionnaire as required pursuant to Section 6.1 (including the information required to be included in such Notice and Questionnaire) and the information set forth in the next sentence. Holder shall promptly furnish to TerreStar all information required to be disclosed in order to make the information previously furnished to TerreStar by Holder not misleading and any other information regarding Holder and the distribution of such Registrable Shares as may be required to be disclosed in a Registration Statement under applicable Law or pursuant to SEC comments. Holder shall not sell any Registrable Shares pursuant to a Registration Statement without delivering, or causing to be delivered, a Prospectus to the purchaser thereof and, following termination of the effectiveness of the Registration Statement, shall notify TerreStar, within 10 Business Days of a request by TerreStar, of the amount of Registrable Shares sold pursuant to such Registration Statement and, in the absence of a response, TerreStar may assume that all of Registrable Shares were so sold.

Section 13.5 Holdback Agreements. To the extent requested in writing by a managing underwriter, if any, of any registration effected pursuant to Section 6.1 or 6.3 which includes Registrable Shares, Holder shall not sell, transfer, sell forward, hedge, enter into any sort of derivative contract pertaining to or otherwise or otherwise dispose of, including in any sale pursuant to Rule 144 under the Securities Act, any TerreStar Shares, or any other equity security of TerreStar or any security convertible into or exchangeable or exercisable for any equity security of TerreStar other than as part of such underwritten public offering during the time period reasonably requested by the managing underwriter, not to exceed 90 days, provided that all of the executive officers and directors of TerreStar enter into similar lock-up agreements of no shorter duration. For the avoidance of doubt, if Holder does not participate in such an underwritten offering, Holder will not be obligated to execute a lock-up agreement or otherwise be bound by these restrictions.

Section 13.6 Registration Expenses. TerreStar shall bear and pay or cause to be paid promptly upon request being made therefor all expenses incident to TerreStar’s performance of or compliance with this ARTICLE VI, including, but not limited to, (a) all SEC and any FINRA registration and filing fees and expenses, (b) all fees and expenses in connection with the qualification of the Registrable Shares for offering and sale under the securities and blue sky Laws referred to in Section 6.2(a)(v), including reasonable fees and disbursements of one counsel for the placement agent or underwriters, if any, in connection with such qualifications, (c) all expenses relating to the preparation, printing, distribution and reproduction of the Shelf Registration Statement, the related Prospectuses, each amendment or supplement to each of the foregoing, the certificates representing the Registrable Shares and all other documents relating hereto, (d) fees and expenses of the transfer agent for the TerreStar Common Stock, (e) fees, disbursements and expenses of counsel and independent certified public accountants of TerreStar (including the expenses of any reports required by the Securities Act or the rules and regulations thereunder to be included or incorporated by reference in the Shelf Registration Statements or “cold comfort” letters required by or incident to such performance and compliance) and (f) fees, expenses and disbursements of any other Persons, including special experts, retained by

D-20

TerreStar in connection with such registration (collectively, the “Registration Expenses”). To the extent that any Registration Expenses are incurred, assumed or paid by Holder or any underwriter or placement agent therefor, TerreStar shall reimburse such Person for the full amount of the Registration Expenses so incurred, assumed or paid promptly after receipt of a documented request therefor. Notwithstanding the foregoing, the Investors shall pay all underwriting discounts and commissions and placement agent fees and commissions attributable to the sale of Investors Shares and the fees and disbursements of advisors or experts retained by the Investors (severally or jointly), but TerreStar shall pay for the fees and expenses of one counsel for the Investors in any Underwritten Offering, not to exceed $150,000.

Section 13.7 Penalties. TerreStar shall pay to Holder, within 5 Business Days after the end of each calendar month in which a Nonregistration Day occurs (or, if the determination of the Fair Value of TerreStar Common Stock requires the determination of its Appraised Value, within 5 Business Days after such determination), an amount, in cash, equal to 0.25% multiplied by the Fair Value per share of TerreStar Common Stock on the last trading day of such month multiplied by the number of Nonregistration Days in such month multiplied by the weighted average number of Registrable Shares to which such Nonregistration Days relate divided by the number of calendar days in such month. Solely for the purposes of the calculation of this penalty (and not for any other purpose under this Agreement), if Holder becomes permitted to sell Registrable Shares pursuant to Rule 144, then the number of Registrable Shares shall be reduced on each day by the number which Holder could have sold pursuant to Rule 144 if, on each day when it was so eligible, it had sold a number of Registrable Shares equal to (a) the number of shares of TerreStar Common Stock permitted to be sold by it pursuant to Rule 144 multiplied by (b) the number of Registrable Shares then owned by Holder divided by (c) the total number of shares of TerreStar Common Stock then owned by Holder.

Section 13.8

Indemnification.

(a) TerreStar shall indemnify and hold harmless Holder, the directors, officers, employees and Affiliates of Holder and each person who controls Holder within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other applicable Law, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any prospectus forming part thereof or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of any prospectus, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that TerreStar will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission from any such document, in reliance upon and in conformity with information provided by any Investor in writing (whether in its Notice and Questionnaire or otherwise). This indemnity agreement will be in addition to any liability that TerreStar may otherwise have.

D-21

(b) Holder shall indemnify and hold harmless TerreStar, each of its directors, each of its officers, and each person, if any, who controls TerreStar within the meaning of either the Securities Act or the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which TerreStar may become subject under the Securities Act, the Exchange Act or other applicable Law, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any prospectus forming part thereof or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the case of any prospectus, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with any information furnished in writing to TerreStar by Holder for use in such Registration Statement or prospectus, and agrees to reimburse TerreStar, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that Holder shall not be liable for any indemnity claims hereunder in excess of the amount of net proceeds received by Holder from the sale of Registrable Shares pursuant to the Registration Statement. This indemnity agreement will be in addition to any liability which Holder may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 6.8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 6.8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it has been materially prejudiced through the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b). If any action shall be brought against an indemnified party and it shall have notified the indemnifying party thereof, the indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified

D-22

party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(d) The provisions of this Section 6.8 and Section 6.9 shall remain in full force and effect, regardless of any investigation made by or on behalf of Holder, TerreStar, or any of the indemnified Persons referred to in this Section 6.8 and Section 6.9, and shall survive the sale by Holder of TerreStar covered by a Registration Statement.

(e) All fees, disbursements and other charges under this Section 6.8 will be reimbursed by the Indemnifying Party promptly as they are incurred.

Section 13.9 Contribution. If the indemnification provided for in Section 6.8 is unavailable or insufficient to hold harmless an indemnified party under Section 6.8(a) or 6.8(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by TerreStar from the offering and sale of the Registrable Shares, on the one hand, and Holder with respect to the sale by Holder of Registrable Shares, on the other, or (ii) if the allocation provided by clause (i) above is not permitted by applicable Law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of TerreStar and Holder on the other with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by TerreStar on the one hand and Holder on the other with respect to such offering and such sale shall be deemed to be in the same proportion as the total net proceeds from the offering of the Investors Shares (excluding discounts and commissions, but before deducting expenses) received by or on behalf of TerreStar, on the one hand, and the total net proceeds (excluding discounts and commissions, but before deducting expenses) received by Holder upon a resale of the Registrable Shares, on the other, bear to the total gross proceeds from the sale all Investors Shares pursuant to the Registration Statement in the offering of the Investors Shares from which the contribution claim arises. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to TerreStar or information supplied by TerreStar on the one hand or to any information contained in the relevant Notice and Questionnaire supplied by Holder on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6.9 were to be determined by pro rata allocation or by any other method of allocation that does not take into

D-23

account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 6.9 shall be deemed to include, for purposes of this Section 6.9, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 6.9, Holder shall not be required to contribute any amount in excess of the amount by which the total price at which the Registrable Shares sold by Holder to any purchaser exceeds the amount of any damages which Holder has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

Section 13.10 Transfer of Registration Rights. Holder may transfer or assign its registration rights under this Agreement to a transferee or assignee; provided, however, that upon or prior to such transfer or assignment TerreStar is provided: (a) written notice by Holder stating the name and address of such transferee or assignee and identifying the Registrable Shares with respect to which such registration rights are being transferred or assigned; and (b) a joinder agreement executed by such transferee or assignee pursuant to which such transferee or assignee agrees to be bound by the terms of this Agreement. Notwithstanding the foregoing, Holder may transfer or assign its rights under this Agreement to a transferee or assignee if such transferee or assignee is (i) an Affiliate, partner or retired partner of any Holder or (ii) any family member or trust for the benefit of Holder, if Holder is an individual. For the purposes of the definitions of “Registrable Share” and “Nonregistration Day,” at any time following any transfer or assignment of a TerreStar Share, such TerreStar Share shall be deemed to be permitted to be resold pursuant to Rule 144 under the Securities Act free of restrictions as to volume and manner of sale if either (i) such TerreStar Share may be so resold or (ii) such TerreStar Share would have been permitted to be so resold had such transfer or assignment not occurred.

ARTICLE XIV.

(a)

by mutual written consent of Holder and TerreStar;
