FORM OF
STOCK ESCROW AGREEMENT






 


THIS
STOCK ESCROW AGREEMENT, dated as of , 2013 (this “Agreement”), by and among Global Defense & National
Security Systems, Inc., a Delaware corporation (the “Company”), Global Defense & National Security Holdings
LLC (the “Sponsor”), and American Stock Transfer & Trust Company (the “Escrow Agent”).


 


WHEREAS,
the Sponsor has agreed to deposit its  2,003,225 shares of the Company’s common stock, par value $0.0001 per share (the
“Common Stock”), purchased on July 19, 2013 (the “Sponsor’s Shares”) in escrow as
hereinafter provided;


 


WHEREAS,
the Company and the Sponsor desire that the Escrow Agent accept the Sponsor’s Shares, in escrow, to be held and disbursed
as hereinafter provided.


 


IT IS AGREED:


 


1.Appointment of Escrow
Agent. The Company and the Sponsor hereby appoint the Escrow Agent to act in accordance with and subject to the terms of this
Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such terms.






 


2.Deposit
of Sponsor’s Shares. On or about the effective date of the Company’s Registration Statement on Form S-1
(File No. 333-) filed under the Securities Act of 1933, as amended (the “Registration Statement”), the Sponsor
shall deliver to the Escrow Agent the certificate representing the Sponsor’s Shares, which certificate shall remain in the
name of the Sponsor, to be held and disbursed subject to the terms and conditions of this Agreement. The Sponsor acknowledges that
the certificate representing the Sponsor’s Shares bears a legend to reflect the deposit of the Sponsor’s Shares under
this Agreement.



 



 


3.Disbursement
of the Sponsor’s Shares. Of the total Sponsor’s Shares, fifty percent (50%) of such shares will be
released from escrow six months after the consummation of a Business Combination (as defined in the Registration Statement), and
the remaining fifty percent (50%) of the Sponsor’s Shares will be released from escrow one year after the consummation of
a Business Combination (the “Escrow Period”); provided, however, that if the over-allotment option (as
described in the Registration Statement) is not exercised in full prior to the expiration of the over-allotment option, then the
Escrow Agent shall release to the Company such number of Sponsor’s Shares as directed in writing by the Company. The Company
shall promptly provide notice of the consummation of a Business Combination to the Escrow Agent. Upon the completion of the Escrow
Period, the Escrow Agent shall automatically disburse the Sponsor’s Shares to the Sponsor upon receipt of written request
therefor from the Company; provided, however, that if the Escrow Agent is notified by the Company pursuant to Section 6.6
hereof that the Company has been liquidated at any time during the Escrow Period, then the Escrow Agent shall promptly destroy
the certificates representing the Sponsor’s Shares. The Escrow Agent shall have no further duties hereunder with respect
to the Sponsor’s Shares after the disbursement or destruction of the Sponsor’s Shares in accordance with this Section
3.
