RECITALS

WHEREAS, GIS is an affiliate of the Company’s sponsor; and

WHEREAS, the Company will be attempting to consummate a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses or assets involving the Company (a “Business Transaction”); and

WHEREAS, GIS may also be seeking investment opportunities which may be a part of, in connection with or deemed a Business Transaction; and

WHEREAS, the Company and GIS each believes it is in their best interests to clarify any potential Business Transaction and investment opportunities for which each party shall have the right of first refusal.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.      Right of First Refusal.

For the term specified in Section 2 of this Agreement and subject to subsections (b), (c) and (d) of this Section 1, GIS hereby grants to the Company a right of first refusal as follows:

(a)         GIS shall not enter into any agreement to purchase or invest in a business in the U.S. defense and national security sectors with an acquisition cost of $40 million or greater without first presenting such suitable opportunity to the Company’s directors, and will not enter into any such agreement until the Company’s directors determine, within the time frame and in the manner specified below, not to pursue such Business Transaction opportunity.

(b)         Notwithstanding anything to the contrary in this Agreement, the Company agrees that any such business entity in which GIS currently invests or with respect to which GIS has initiated any contacts or entered into any discussions or negotiations, formal or informal, regarding their respective acquisition of, or investment in, such business prior to the completion of the Company’s initial public offering, as set forth in the Registration Statement, will not be a potential acquisition target for the Company, unless GIS declines to pursue such respective business opportunity and notifies the Company of the same in writing.

(c)         After review of any potential Business Transaction or investment opportunity, the Company may release the right of first refusal set forth in this Section 1(a) with respect to such Business Transaction or suitable opportunity.  Decisions by the Company to release GIS to pursue such suitable opportunity will be made by a majority of the Company’s directors.

(d)         GIS shall provide written notice to the Company of any such suitable opportunity brought to its attention by its current directors and officers within ten (10) business days of its identification of such suitable opportunity. Any right of first refusal granted shall expire only pursuant to Section 1(c).

2.      Term. This Agreement shall become effective on its execution and shall remain in effect for a period to expire upon the earlier of: (i) the consummation by the Company of a Business Transaction or (ii) 21 months from the closing of the Company's initial public offering.
