Any such withheld Escrow Cash or Escrow Shares shall be delivered to SpaceDev promptly after the expiration of the Escrow Period, and shall be delivered by SpaceDev to the shareholders to whom such Escrow Cash or Escrow Shares would have otherwise been distributed upon surrender of their certificates representing Company Common Stock (or delivery of such affidavit and bond, if any). The Escrow Agent shall distribute Escrow Cash and Escrow Shares to the respective Shareholders by mailing a check representing the funds, or directing the transfer agent for the SpaceDev common stock to deliver a stock certificate representing such Escrow Shares, due to such Shareholder at its address shown on Exhibit A.

If any controversy arises between the parties to this Agreement, or with any other Person, concerning the subject matter of this Agreement, the Escrow Agent shall not be required to determine the controversy or to take any action regarding it. Furthermore, the Escrow Agent may file an action of interpleader requiring the parties hereto to answer and litigate any claims and rights amongst themselves. The Escrow Agent is authorized to deposit with the clerk of the court all documents, the Escrow Cash, the Escrow Shares, the Expense Shares or any Permitted Investments or other assets being held in the Escrow Account or Expense Fund; provided, however, that all costs, expenses, charges and reasonable attorney fees incurred by the Escrow Agent due to the interpleader action shall be reimbursed equally by the Shareholders (subject to Section 5.12), on the one hand, and SpaceDev, on the other hand, it being agreed and understood that the Escrow Agent shall have a prior lien upon the Escrow Cash and the Escrow Shares with respect to its costs, expenses, charges and reasonable attorney fees incurred by the Escrow Agent due to the interpleader action, superior to the interests of any other Person. Upon initiating such action, the Escrow Agent shall be fully released and discharged of and from all obligations and liability imposed by the terms of this Agreement, except for any liability for obligations or acts or omissions that have already occurred, and only to the extent set forth herein. PAGE 11 5.7 Indemnification. SpaceDev and the Shareholders (subject to Section 5.12), and their respective successors and assigns, shall jointly and severally indemnify and hold the Escrow Agent harmless against any and all losses, claims, damages, liabilities and expenses, including reasonable costs of investigation, attorneys fees and disbursements, that may be imposed on the Escrow Agent or incurred by the Escrow Agent in connection with the performance of its duties under this Agreement. Such indemnification shall survive the resignation or removal of the Escrow Agent, or the termination of this Agreement. 5.8 Resignation and Removal. The Escrow Agent may resign at any time upon thirty days written notice to SpaceDev and the Shareholder Agent, and the duties of the Escrow Agent shall terminate at the time specified in such notice (but not less than thirty days after delivery to SpaceDev). The Escrow Agent may be removed at any time by notice from SpaceDev, and the duties of the Escrow Agent shall terminate at the time specified in such notice. Upon the termination of its duties hereunder, the Escrow Agent shall promptly deliver the balance of the cash, shares or other assets, and any documentation or notices relating to the Escrow Account, Expense Fund or this Agreement, then in its possession to a successor escrow agent, as identified by a written notice delivered by SpaceDev to the Escrow Agent. 5.9 Successors. SpaceDev may appoint the successor escrow agent (i) without the consent of the Shareholder Agent if such successor is a commercial bank organized under the laws of the United States of America, or any State thereof, having an aggregate capital and surplus in excess of $50,000,000 and being a "securities intermediary" for purposes of the applicable Uniform Commercial Code, or (ii) with the consent of the Shareholder Agent (which the Shareholder Agent may not unreasonably withhold, delay or condition). If SpaceDev shall have failed to appoint a successor escrow agent prior to the termination of the Escrow Agent's duties as provided in this Section 5.8, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor escrow agent or for other appropriate relief, with due regard to the qualifications for a successor escrow agent specified in clause (i) next preceding, and any such resulting appointment shall be binding upon all of the parties hereto and beneficiaries hereof. The successor escrow agent shall execute and deliver an instrument accepting such appointment, and it shall, without further acts, be vested with all the estates, properties, rights, powers and duties (but not accrued liabilities) of the predecessor escrow agent as if originally named as escrow agent. Upon resignation in accordance with this Section 5.8, the Escrow Agent shall be discharged from any further duties and liability under this Agreement, except for any liability for obligations or acts or omissions that have already occurred, and only to the extent set forth herein. 5.10 Fees. All fees of the Escrow Agent for performance of its duties under this Agreement shall be paid by SpaceDev. 5.11 Set-Off. In the event that the Escrow Agent is authorized to make disbursements to any party to or beneficiary of this Agreement pursuant to and in accordance with the terms of this Agreement, and fees and expenses are due and payable to the Escrow Agent pursuant to the terms of this Agreement by the party or beneficiary receiving such disbursement, the Escrow Agent is hereby authorized to offset such amounts due and payable to it against such disbursement to such party or beneficiary. 5.12 Shareholder Payments. The obligations of the Shareholders to make payments to the Escrow Agent hereunder, other than pursuant to Section 6 (as to which the limitations of this Section 5.12 shall not apply), shall be limited to the assets held in the Escrow Account. If such assets shall be insufficient to pay the fees of or other amounts due to the Escrow Agent hereunder, SpaceDev shall make such payments on behalf of the Shareholders (it being understood that SpaceDev shall have the right to recover one-half of such payment from the Key Shareholders). PAGE 12 6. Tax Matters. The Escrow Agent shall be responsible for reporting any interest earned, as of each calendar year-end, on the Escrow Cash or Permitted Investments, or any cash dividends or other distributions made in respect of the Escrow Shares or Expense Shares, to the IRS, whether or not such income was distributed by the Escrow Agent during any particular year. The Escrow Agent may request specific instructions regarding such reporting from SpaceDev and, in the event of the failure of SpaceDev to reasonably respond to such request within thirty days, the Escrow Agent may, at the expense of SpaceDev, make such request of its tax accountants or counsel. The Shareholder Agent shall provide a completed IRS Form W-8 (an original W-8 is required) or Form W-9 to the Escrow Agent upon the signing of this Agreement. The Escrow Agent may delay accepting any Escrow Cash until the IRS forms have been provided. Each Shareholder, severally but not jointly, covenants and agrees to indemnify and hold the Escrow Agent harmless against all liability for tax withholding or reporting for any payments made by the Escrow Agent to such Shareholder pursuant to this Agreement. The Escrow Agent shall have no responsibility for the preparation and/or filing of any tax or information return, other than 1099-INT reporting, with respect to any transaction, whether or not related to the Agreement or any Related Agreements, that occurs outside of the Escrow Account and Expense Fund. 7.
