The Purchaser shall indemnify and hold harmless TerreStar and its respective officers, directors, employees and representatives from and against any and all claims, damages, losses, liabilities, obligations, costs and expenses (including attorney's fees) ("LOSSES") that may be incurred by or asserted or awarded against any such person, in each case arising out of or in connection with: (a) any offering of securities by the Purchaser the proceeds of which are used to fund the investment contemplated by this Agreement to the extent such losses do not directly relate to or arise from a breach by TerreStar of its representations, warranties, covenants or agreements hereunder or in any Transaction Document, (b) the breach by the Purchaser of any representation or warranty made to TerreStar by the Purchaser herein or in any document delivered pursuant hereto, or (c) the breach by the Purchaser of any covenant or agreement contained herein or in any document delivered pursuant hereto. 5.2. Indemnification by TerreStar. TerreStar shall indemnify and hold harmless the Purchaser and its officers, directors, employees and representatives from and against any and all Losses that may be incurred by or asserted or awarded against any such person, in each case arising out of or in connection with: (a) the breach by TerreStar of any representation or warranty made to the Purchaser by TerreStar herein or in any document delivered pursuant hereto and thereto, or (b) the breach by TerreStar of any covenant or agreement contained herein or in any document delivered pursuant hereto. 5.3. No Duplication of Remedies. To the extent any party may have more than one remedy for any Losses incurred by it, it may pursue all available remedies but in no event shall be entitled to collect and retain any amount hereunder in excess of its Losses. 5.4. Notice of Claims. All claims for indemnification hereunder shall be resolved in accordance with the following procedures: (a) If the party seeking indemnification (the "INDEMNIFIED PARTY") has incurred or reasonably believes that it may incur any Losses, it shall deliver promptly written notice to the indemnifying party (the "INDEMNIFYING PARTY"), setting forth the nature and amount of the Losses or potential Losses, if possible (a "CLAIM NOTICE"). If an Indemnified Party receives notice of a third-party claim for which it intends to seek indemnification hereunder, it shall give the Indemnifying Party written notice of such claim, so that the Indemnifying Party's defense of such claim under this Agreement may be timely instituted. The failure by an Indemnified Party to provide such written notice shall not constitute a waiver of the Indemnified Party's right to indemnity unless such failure has prejudiced the Indemnifying Party's ability to defend such claim, and then only to the extent of such prejudice. (b) If, after receiving a Claim Notice, the Indemnifying Party desires to dispute such claim or the amount claimed in the Claim Notice, it shall deliver to the Indemnified Party a written objection to such claim or payment setting forth the basis for disputing such claim or payment. Such notice shall be delivered within 30 days after the date the Claim Notice to which it relates is received by the Indemnifying Party. If no such notice is received within the aforementioned 30-day period, the Indemnified Party shall be entitled to payment for such Losses from the Indemnifying Party within 10 days of the end of such 30-day objection period. 14 (c) If the Indemnifying Party shall agree that it is responsible for all amounts that may be recovered in connection with a third-party claim, action or suit (including waiving any deductible or limit that might otherwise apply under this Article V) the Indemnifying Party shall have the right to conduct and control through counsel of its own choosing, which counsel shall be reasonably acceptable to the Indemnified Party, any third-party claim, action or suit; provided, that the Indemnifying Party (i) demonstrates to the Indemnified Party's reasonable satisfaction that it has the financial ability to mount an appropriate defense of such claim and (ii) diligently contests and defends such claim. The Indemnified Party shall be entitled at any time, at its own cost and expense (except that such cost and expense shall be paid by the Indemnifying Party if the Indemnified Party reasonably determines that the Indemnifying Party is not adequately representing or, because of a conflict of interest, may not adequately represent the interests of the Indemnified Party) to participate in such defense and to be represented by attorneys of its choosing. Except with the prior written consent of the Indemnified Party no Indemnifying Party, in the defense of such claim or litigation, shall consent to entry of any judgment or order, interim or otherwise, or enter into any settlement that provides for injunctive or other nonmonetary relief affecting the Indemnified Party or that does not include as an unconditional term thereof the giving by each claimant or plaintiff to such Indemnified Party of a release from all liability with respect to such claim or litigation. (d) In the event that the Indemnifying Party does not elect to defend against any third-party claim, the Indemnified Party may defend against such claim in such manner as it may deem appropriate and the Indemnifying Party shall be liable for any legal expenses reasonably incurred in connection with such defense; PROVIDED, HOWEVER, that the Indemnified Party shall not, without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, settle or consent to the entry of judgment with respect to such third-party claim. (e) In the event of any claim by a third party, the parties hereto agree that they will cooperate fully with each other in connection with the defense or settlement of such matter. 5.5. Limitation on Amounts. The Indemnifying Party shall not be obligated to pay any amounts for indemnification under this Article V with respect to breaches of representations and warranties until the aggregate indemnification obligation of such Indemnifying Party hereunder exceeds $250,000, whereupon the Indemnifying Party shall be liable for all amounts for which indemnification may be sought which exceed $250,000. No Indemnifying Party's liability under this Article V shall exceed the amount of the purchase price for the Shares pursuant to this Agreement. ARTICLE VI GENERAL PROVISIONS ------------------ 6.1. Confidentiality. Each party hereto agrees that, except with the prior written consent of the other party, it shall at all times keep confidential and not divulge, furnish or make accessible to anyone any confidential information, knowledge or data concerning or relating to the business or financial affairs of the other parties to which such party has been or shall become privy by reason of this Agreement or the other Transaction 15 Documents, discussions or negotiations relating to this Agreement or the other Transaction Documents, the performance of its obligations hereunder or the ownership of the Shares purchased hereunder.

Delays or Omissions.

Any 16 waiver, permit, consent or approval of any kind or character on the Purchaser's part of any breach, default or noncompliance under this Agreement or the other Transaction Documents or any waiver on such party's part of any provisions or conditions of this Agreement or the other Transaction Documents must be in writing and shall be effective only to the extent specifically set forth in such writing.
