Such Purchaser understands that the Purchased Preferred Shares, the Underlying Shares and the Fee Shares it is purchasing are characterized as “restricted securities” under the federal securities Laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such Laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, such Purchaser represents that it is knowledgeable with respect to Rule 144 under the Securities Act.

Section 4.10 Certain Fees.

No fees or commissions will be payable by such Purchaser to brokers, finders or investment bankers with respect to the sale of any of the Purchased Preferred Shares, the Underlying Shares or the Fee Shares or the consummation of the transactions contemplated by this Agreement. The Company will not be liable for any such fees or commissions. Such Purchaser agrees, severally and not jointly with the other Purchasers, that it will indemnify and hold harmless the Company from and against any and all claims, demands or liabilities for broker’s, finder’s, placement or other similar fees or commissions incurred by such Purchaser or alleged to have been incurred by such Purchaser in connection with the purchase of Purchased Preferred Shares, the Underlying Shares or the Fee Shares or the consummation of the transactions contemplated by this Agreement.

Section 4.11 Legend.

It is understood that the certificates evidencing the Purchased Preferred Shares, the Underlying Shares and the Fee Shares initially will bear the following legend: “These securities have not been registered under the Securities Act of 1933, as amended. These securities may not be sold, offered for sale, pledged (except in connection with a bona fide margin account or other loan or financing arrangement secured by these securities) or hypothecated in the absence of a registration statement in effect with respect to the securities under such Act or pursuant to an exemption from registration thereunder and, in the case of a transaction exempt from registration, unless sold pursuant to Rule 144 under such Act or the issuer has received documentation reasonably satisfactory to it that such transaction does not require registration under such Act.”

For the avoidance of doubt, the Underlying Shares may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by such Underlying Shares and such pledge shall not be deemed to be a transfer, sale or assignment of such Underlying Shares, and no buyer effecting such a pledge shall be required to provide the

Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Basic Document.

Section 4.12 No Side Agreements.

Except for the confidentiality agreements entered into by and between such Purchaser and the Company, there are no other agreements by, among or between the Company or its Affiliates, on the one hand, and such Purchaser or its Affiliates, on the other hand, with respect to the transactions contemplated hereby nor promises or inducements for future transactions between or among any of such parties.

ARTICLE V.
COVENANTS

Section 5.1 Commitment Fees.

For each $1,000,000 of Commitment Amount as set forth opposite each Purchaser on Schedule 2.1, such Purchaser shall receive 26,000 shares of Common Stock from the Company, and the Company shall issue such shares of Common Stock to such Purchaser (collectively, the “Commitment Fees”) promptly following the Effective Date.

Section 5.2 Conversion Rights.

Each Purchased Preferred Share shall be convertible into a specified number of shares of Common Stock, which shall be equivalent to the number resulting from the calculation of the following formula: the Original Purchase Price divided by the average of (x) the average closing price of the Common Stock for the five (5) Business Days prior to January 28, 2008 and (y) the average of the closing price of the Common Stock for the five (5) Business Days prior to the Company’s receipt of written notification from NASA indicating the Company’s receipt of a COTS Award of at least $120,000,000.

Section 5.3 Put Rights.

If the Purchased Preferred Shares are not converted into shares of Common Stock within one year of the Closing Date, each Purchaser has the right to require the Company to repurchase its Purchased Preferred Shares (the “Put Right”) at a price equal to 120% of the Original Purchase Price (the “Put Price”). In the event that a Purchaser elects to exercise its Put Right, such Purchaser must give written notice (the “Put Notice”) to the Company within thirty (30) days following the first anniversary of the Closing Date. Upon the Company’s receipt of the Put Notice, the Company shall be obligated to repurchase the appropriate portion of the Purchased Preferred Shares owned by such Purchaser (the “Put Preferred Shares”) at the Put Price. Such repurchase shall take place on the 40th Business Day following the Closing Date, or such other time as such parties shall mutually agree to in writing. The payment of the consideration for the repurchase of the Put Preferred Shares shall be made in immediately available funds by wire transfer to the account specified by the Purchaser in the Put Notice. Upon the Company’s payment hereunder, the Company’s obligations with respect to the repurchased Put Preferred Shares shall terminate. Such Purchaser who exercises its Put Right

agrees to take all reasonable action to assist the Company in the repurchase of the Put Preferred Shares, including the delivery of the certificates representing such repurchased Put Preferred Shares to the Company or to the Company’s stock transfer agent. This Put Right is non-transferable and shall only apply to the Purchasers signatory hereto up to the respective amounts of each Purchaser’s Commitment Amount as set forth on Schedule 2.1 attached hereto.

Section 5.4 Stock Exchange Approval.

The Company shall use its commercially reasonable efforts to obtain in a timely manner the required final consents, approvals and authorizations of the Stock Exchange for the issuance and listing of the Underlying Shares and the Fee Shares.

Section 5.5 Taking of Necessary Action.

Each of the Parties hereto shall use its commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do or cause to be done all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions contemplated by this Agreement. Without limiting the foregoing, the Company and each Purchaser will, and the Company shall cause each of its Subsidiaries to, use its commercially reasonable efforts to make all filings and obtain all consents of Governmental Authorities that may be necessary or, in the reasonable opinion of the Purchasers or the Company, as the case may be, advisable for the consummation of the transactions contemplated by this Agreement and the other Basic Documents.

Section 5.6 Non-Disclosure; Interim Public Filings.

Within four (4) Business Days following the Effective Date, the Company shall issue a press release acceptable to the Purchasers disclosing all material terms of the transactions contemplated hereby and file a report on Form 8-K with the Commission (the “8-K Filing”) describing the terms of the transactions contemplated by this Agreement and the other Basic Documents and including as exhibits to such report on Form 8-K this Agreement and the other Basic Documents, in the form required by the Exchange Act. Thereafter, the Company shall timely file any filings and notices required by the Commission or applicable Law with respect to the transactions contemplated hereby and provide copies thereof to the Purchasers promptly after filing. Except with respect to the 8-K Filing and the press release referenced above (a copy of which will be provided to the Purchasers for their review as early as practicable prior to its filing), the Company shall, at least one Business Day prior to the filing or dissemination of any disclosure required by this Section 5.6, provide a copy thereof to the Purchasers for their review. The Company and the Purchasers shall consult with each other in issuing any press releases or otherwise making public statements or filings and other communications with the Commission or any regulatory agency or the Stock Exchange with respect to the transactions contemplated hereby, and neither Party shall issue any such press release or otherwise make any such public statement, filing or other communication without the prior consent of the other, except if such disclosure is required by Law, in which case the disclosing Party shall promptly provide the other Party with prior notice of such public statement, filing or other communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any press release, without the prior written

consent of such Purchaser except to the extent the names of the Purchasers are included in this Agreement as filed as an exhibit to the 8-K Filing and the press release referred to in the first sentence above.

Section 5.7 Use of Proceeds.

The Company shall use the collective proceeds from the sale of the Purchased Preferred Shares for working capital purposes, fulfillment of the obligations under the COTS Space Act Agreement and general corporate purposes.

Section 5.8 Updating Disclosures.

(a) Prior to the Closing Date, the Company may, at its sole option, update its schedules, representations and warranties set forth in ARTICLE III with additional disclosures that have arisen since the Effective Date. In the event that the Company chooses to exercise such option, the Company shall provide such additional disclosures to the Purchasers by written notice in accordance with Section 9.7 no later than five (5) Business Days prior to the Closing Date.

(b) Upon receipt of written notice from the Company under Section 5.8(a) above, each Purchaser shall have until two (2) Business Days after receipt of such notice to request the termination of this Agreement by delivering written notice thereof to the Company in accordance with Section 9.7. In the event that Purchaser(s) holding 50% or more of the aggregate Commitment Amounts set forth in Schedule 2.1 (collectively, the “Majority Purchasers”) request such termination, then the Agreement shall be terminated. However, in the event that the Majority Purchasers do not request the termination of the Agreement, then the additional disclosures delivered by the Company shall be deemed to be part of the disclosures set forth in its schedules, representations and warranties in ARTICLE III as delivered to Purchaser on the date of this Agreement for all purposes of this Agreement, including this ARTICLE V.

INDEMNIFICATION, COSTS AND EXPENSES

Section 8.1 Indemnification by the Company.

The Company agrees to indemnify each Purchaser and its Representatives from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to (i) any actual or proposed use by the Company of the proceeds of any sale of the Purchased Preferred Shares or (ii) the breach of any of the representations, warranties or covenants of the Company contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to one year after the Closing.

Section 8.2 Indemnification by the Purchasers.

The Purchasers, severally but not jointly, agree to indemnify the Company and its Representatives from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay and reimburse each of them for all costs, losses, liabilities, damages or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of or in any way related to the breach of any of the representations, warranties or covenants of the Purchasers contained herein; provided that such claim for indemnification relating to a breach of a representation or warranty is made prior to one year after the Closing.

Section 8.3 Indemnification Procedure.

Promptly after any party seeking reimbursement has received notice of any indemnifiable claim hereunder (the “Indemnified Party”), or the commencement of any action or proceeding by a third party, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party

shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel with consent of the Indemnifying Party and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party (which consent shall not be unreasonably withheld), unless the settlement thereof imposes no liability or obligation on, involves no admission of wrongdoing or malfeasance by, and includes a complete release from liability of, the Indemnified Party.
