Purpose of Transaction. ITEM 4 TO THE SCHEDULE 13D/A FILED BY THE REPORTING PERSONS ON AUGUST 25, 2008 IS AMENDED BY ADDING THE FOLLOWING TO THE END THEREOF: The Reporting Persons have entered into an agreement to acquire additional securities of the Issuer for investment. Other than as expressly set forth in Item 4 and Item 6 herein, the Reporting Persons have no plans or proposals as of the date of this filing which relate to, or would result in, any of the actions enumerated in Item 4 of the instructions to Schedule 13D. On September 12, 2008, Harbinger Capital Partners Master Fund I, Ltd. (the "Master Fund") and Harbinger Special Situations Fund, L.P. (the "Special Fund" and, together with the Master Fund, "Harbinger") entered into a Stock Purchase Agreement (the "Stock Purchase Agreement") with Motient Ventures Holdings Inc. ("Motient"), pursuant to which Harbinger agreed to purchase from Motient 23,376,074 shares (the "Initial Purchased Shares") of non-voting common stock, par value $0.01 per share of the Issuer (the "Non-Voting Common Stock"), for an aggregate purchase price of $97,010,707 (the "Purchase Price"). The Purchase Price paid by Harbinger for the Initial Purchased Shares represents a price of $4.15 per Purchased Share. The transactions contemplated by the Stock Purchase Agreement closed on September 12, 2008 (the "Closing Date"). Additionally, pursuant to an option granted to Harbinger in the Stock Purchase Agreement to purchase from Motient additional shares of Non-Voting Common Stock on or before September 18, 2008, Harbinger purchased an additional 250,000 shares (the "Additional Shares", and together with the Initial Purchased Shares, the "Purchased Shares") of Non-Voting Common Stock on September 16, 2008, for an aggregate purchase price of $1,037,500, on the same terms and subject to the same conditions as the purchase of the Initial Purchased Shares pursuant to the Stock Purchase Agreement and the Pledge Agreement. The purchase price paid by Harbinger for the Additional Shares represents a price of $4.15 per Additional Share, and the closing of the purchase of the Additional Shares occurred on September 16, 2008. In exchange for the aggregate purchase price paid by Harbinger for the Purchased Shares, Motient delivered or agreed to deliver (i) to Harbinger, all instruments reasonably necessary to indefeasibly transfer to Harbinger 15,719,337 of the Initial Purchased Shares and (ii) to Goldberg, Godles, Wiener & Wright, in its capacity as Collateral Agent (the "Collateral Agent") under the Pledge Agreement among Harbinger, Motient and the Collateral Agent and dated September 12, 2008 (the "Pledge Agreement"), certificates representing 7,656,737 of the Initial Purchased Shares and 250,000 of the Additional Shares (collectively, the "Remaining Shares"), together with signed stock powers and other instruments executed in blank to permit the Collateral Agent to effect the delivery and transfer of the Remaining Shares in accordance with the terms of the Stock Purchase Agreement and the Pledge Agreement. Of the 15,719,337 Initial Purchased Shares purchased by Harbinger, 7,302,696 were purchased by the Master Fund and 8,416,641 were purchased by the Special Fund. In accordance with the terms of the Stock Purchase Agreement and the Pledge Agreement, the Remaining Shares, together with other securities or other property (other than ordinary cash dividends) delivered to the Collateral Agent as a result of any split, combination or reclassification of the Non-Voting Common Stock effected by the Issuer or any dividend declared by the Issuer (any such securities or other property, together with the Remaining Shares, the "Pledged Property"), will be held as pledged property by the Collateral Agent, for the benefit of Harbinger. The Collateral Agent shall transfer and deliver the Pledged Property to (i) Harbinger or its designee in the event Harbinger has obtained any necessary approvals from the Federal Communications Commission (the "FCC") with respect to Harbinger's pending application seeking authority to own up to 100% of the Common Stock of the Issuer (the "FCC Consent"), (ii) Harbinger or its designee in the event the Collateral Agent has determined that the FCC Consent is no longer required in order for such transfer and delivery to comply with the Communications Act of 1934, or (iii) a third party pursuant to a sale of the Pledged Property, with the proceeds of such sale to be remitted to Harbinger, in the event Harbinger is unable to obtain the FCC Consent, or has determined not to seek or abandoned efforts to seek the FCC Consent. The date upon which the Collateral Agent transfers and delivers the Pledged Property to Harbinger or a third party is referred to as the "Final Settlement Date". Until the Final Settlement Date, (i) title to the Pledged Property will remain vested solely in Motient and the Pledged Property will remain registered on the books of the Issuer in the name of Motient or its respective nominees, (ii) Motient will have the right to vote the Remaining Shares and other voting securities included within the Pledged Property, and (iii) Motient will have the right to receive and retain any cash dividends declared or paid by the Issuer with respect to the Remaining Shares or other securities included within the Pledged Property. Motient has agreed to vote the Purchased Shares in favor of the proposed amendment to the Issuer's certificate of incorporation in order to increase the number of shares of Non-Voting Common Stock authorized for issuance from 100,000,000 to 125,000,000, as set forth in more detail in the Issuer's preliminary proxy statement filed with the Securities Exchange Commission on August 22, 2008. Harbinger disclaims any and all beneficial ownership of the Pledged Property until such time as the Pledged Property is transferred and delivered to Harbinger or one of its affiliates in accordance with the terms of the Pledge Agreement and the Stock Purchase Agreement. In connection with the Stock Purchase Agreement, Harbinger and the Issuer also entered into a letter agreement with respect to the Initial Purchased Shares on the Closing Date, and a letter agreement with respect to the Additional Shares on September 16, 2008 (collectively, the "Letter Agreements"), pursuant to which the Issuer (i) agreed to exchange 67,701 of the Initial Purchased Shares for shares of voting common stock, par value $0.01 per share of the Issuer (the "Voting Shares"), on a one-to-one basis as promptly as practicable after the Closing Date, (ii) agreed to exchange any or all of the remaining Purchased Shares for Voting Shares at any time or from time to time after the Closing Date upon the request of Harbinger (or, with respect to the Remaining Shares, upon the request of the third party purchaser of the Remaining Shares in the event Harbinger is unable to obtain the FCC Consent, or has determined not to seek or abandoned efforts to seek the FCC Consent, and the Remaining Shares are sold to a third party pursuant to the Pledge Agreement), and (iii) consented to the sale of the Purchased Shares by Motient to Harbinger. The Issuer also agreed to amend the Registration Rights Agreement between the Issuer, Mobile Satellite Ventures L.P., Mobile Satellite Ventures Subsidiary LLC, Harbinger, Harbinger Capital Partners Fund I, L.P., and Harbinger Co-Investment Fund, L.P., dated July 24, 2008 (the "Registration Rights Agreement") such that the definition of "Registrable Shares" therein includes the Purchased Shares. In the event Harbinger is unable to obtain the FCC Consent, or has determined not to seek or abandoned efforts to seek the FCC Consent, and some or all of the Remaining Shares are sold to a third party, the Issuer has agreed to enter into a registration rights agreement with such third party providing for a shelf resale registration statement with respect to such Remaining Shares. In accordance with the Letter Agreements, in addition to the 67,701 Initial Purchased Shares to be exchanged for Voting Shares, Harbinger has elected as of the time of this filing to exchange an additional 6,286,214 of the Purchased Shares for Voting Shares. A copy of the Stock Purchase Agreement is filed as Exhibit P hereto and is incorporated herein by reference. A copy of the Pledge Agreement is filed as Exhibit Q hereto and is incorporated herein by reference. A copy of the Letter Agreements are filed as Exhibits R and S hereto and are incorporated herein by reference.

The Reporting Persons reserve the right to effect transactions that would change the number of shares they may be deemed to beneficially own. The Reporting Persons reserve the right to act in concert with any other stockholders of the Issuer, or other persons, for a common purpose should it determine to do so, and/or to recommend courses of actions to the Issuer's management, the Board of Directors, the Issuer's stockholders and others. -------------------------------------------------------------------------------- Item 5.
