AMENDED AND RESTATED BACKSTOP COMMON
STOCK PURCHASE AGREEMENT


 


This Amended and Restated
Backstop Common Stock Purchase Agreement (this “Agreement”), is entered into as of October 17, 2015, by and
between Global Defense & National Security Systems, Inc., a Delaware corporation (the “Company”), and Global
Defense & National Security Holdings LLC, a Delaware limited liability company (the “Purchaser”). Capitalized
terms used and not otherwise defined herein shall have the respective meanings ascribed to them in the Stock Purchase Agreement
(as defined below).


 


WHEREAS, the
Company is a party to that certain Stock Purchase Agreement, dated as of June 8, 2015 (the “Stock Purchase Agreement”),
among the Company, the Purchaser, STG Group, Inc. (“STG”), the Stockholders named therein and Simon Lee, as
Stockholders’ Representative thereunder, with respect to a proposed transaction involving the Company and STG as described
therein (the “Transaction”); and


 


WHEREAS, the
Purchaser desires to purchase, and the Company desires to sell to the Purchaser, shares of the common stock of the Company, par
value $0.0001 per share (“Common Stock”), pursuant to the terms and conditions set forth herein.


 


NOW, THEREFORE,
in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for other
good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree
as follows:


 


1.                 
Backstop Purchases. Subject to the terms and conditions contained in this Agreement, the Company grants the
Purchaser the right to purchase (the “Backstop Purchase”) shares of Common Stock from the Company, at a purchase
price of $10.61 per share (the “Per Share Purchase Price”), payable by the Purchaser by wire transfer of immediately
available funds at the closing of the Transaction (the “Closing”). The purchase right provided in this Agreement
can only be exercised only in the event, and to the extent, that the Company determines that it will not meet the Threshold Cash
Amount (as defined below). The term “Threshold Cash Amount” means Twenty Million Dollars ($20,000,000) in cash available
to the Company from (1) the Trust Fund, following the payment in full to the Company’s stockholders who have requested to
be redeemed in connection with the Closing, and (2) the payment of any aggregate purchase price for the Backstop Purchase. For
the avoidance of doubt, any purchase of shares of Common Stock pursuant to this Section shall be at the Purchaser’s sole
discretion.


 


2.                 
Closing.


 


(a)          Purchase Price. At the Closing, the Purchaser shall deliver to the Company the Per Share Purchase Price for all of the shares
being purchased by the Purchaser.


 


(b)          Certificates. At the Closing, the Company shall deliver to the Purchaser the shares purchased by the Purchaser pursuant
to the Backstop Purchase (the “Shares”).


 


(c)          Legend. Each certificate evidencing the Shares and each certificate issued in exchange for or upon the transfer of any Shares
shall be stamped or otherwise imprinted with a legend in substantially the following form:


 


“THE SECURITIES REPRESENTED
BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES MAY NOT BE SOLD, OFFERED
FOR SALE, PLEDGED OR HYPOTHECATED IN THEABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR UNLESS
SUCH REGISTRATION IS NOT REQUIRED IN THE OPINION OF COUNSEL FOR THE COMPANY.”


 


(d)         Registration Rights.  At the Closing, the Company and the Purchaser shall enter into an amendment to that certain Registration
Rights Agreement, dated as of October 23, 2013, by and between the Company and the Purchaser, to provide that the Shares shall
be considered “Registrable Securities” as defined therein.


 




     


     


    

 


(e)          Mutual
Closing Conditions. The obligations of each party hereto to purchase shares of Common Stock under this Agreement shall be subject
to the fulfillment, at or prior to the Closing, of each of the following conditions:


 


(i)           The
Transaction shall be consummated concurrently with or immediately following the purchase of the Shares.


 


(ii)          The
representations and warranties of the other party in this Agreement shall have been true and correct as of the date hereof and
shall be true and correct as of the Closing with the same effect as though such representations and warranties had been made on
and as of such date (other than any such representation or warranty that is made by its terms as of a specified date, which shall
be true and correct as of such specified date).


 


(iii)         No
order, writ, judgment, injunction, decree, determination, or award shall have been entered by or with any governmental, regulatory,
or administrative authority or any court, tribunal, or judicial, or arbitral body, and no other legal restraint or prohibition
shall be in effect, preventing the purchase of the Shares.


 


3.                 
Representations and Warranties of the Purchaser.  The Purchaser represents and warrants to the Company as follows:


 


(a)          Organization
and Good Standing. The Purchaser is a limited liability company duly organized, validly existing, and in good standing under
the laws of the State of Delaware.


 


(b)          Power
and Authority; Enforceability. This Agreement constitutes the legal, valid, and binding obligation of the Purchaser, enforceable
against the Purchaser in accordance with its terms. The Purchaser has full entity power and authority to execute and deliver this
Agreement and to perform its obligations hereunder. The Purchaser has taken all actions necessary to authorize the execution and
delivery of this Agreement, the performance of its obligations hereunder and the consummation of the transactions contemplated
hereby. This Agreement has been duly authorized, executed and delivered by the Purchaser.


 


(c)          Investment
Representations.


 


(i)           The
Purchaser is an “accredited investor” as defined in Rule 501 of Regulation D under the Securities Act of
1933, as amended (the “Securities Act”).


 


(ii)          The
Purchaser has received, has thoroughly read, is familiar with and understands the contents of this Agreement.


 


(iii)         The
Purchaser hereby acknowledges that an investment in the Shares involves certain significant risks. The Purchaser acknowledges that
there is a substantial risk that it will lose all or a portion of its investment and that it is financially capable of bearing
the risk of such investment for an indefinite period of time. The Purchaser has no need for liquidity in its investment in the
Shares for the foreseeable future and is able to bear the risk of that investment for an indefinite period. The Purchaser’s
present financial condition is such that the Purchaser is under no present or contemplated future need to dispose of any portion
of the Shares purchased hereby to satisfy any existing or contemplated undertaking, need or indebtedness. The Purchaser’s
overall commitment to investments which are not readily marketable is not disproportionate to its net worth and the investment
in the Company will not cause such overall commitment to become excessive.


 


(iv)        The
Purchaser acknowledges that the Shares have not been registered under the Securities Act, or any state securities act, and are
being sold on the basis of exemptions from registration under the Securities Act and applicable state securities acts. Reliance
on such exemptions, where applicable, is predicated in part on the accuracy of the Purchaser’s representations and warranties
set forth herein. The Purchaser acknowledges and hereby agrees that the Shares will not be transferable under any circumstances
unless the Shares are registered in accordance with federal and state securities laws or the Purchaser finds and complies with
an available exemption under such laws. Accordingly, the Purchaser hereby acknowledges that there can be no assurance that it will
be able to liquidate its investment in the Company.

(v)         There
are substantial risk factors pertaining to an investment in the Company. The Purchaser acknowledges that it has read the information
set forth above regarding certain of such risks and is familiar with the nature and scope of all such risks, including, without
limitation, risks arising from the fact that the Company is an entity with limited operating history and financial resources; and
the Purchaser is fully able to bear the economic risks of such investment for an indefinite period, and can afford a complete loss
thereof.


 


(vi)        The
Purchaser has been given the opportunity to (i) ask questions of and receive answers from the Company and its designated representatives
concerning the terms and conditions of the purchase of the Shares, the Company and the business and financial condition of the
Company and (ii) obtain any additional information that the Company possesses or can acquire without unreasonable effort or
expense that is necessary to assist the Purchaser in evaluating the advisability of the purchase of the Shares and an investment
in the Company. The Purchaser further represents and warrants that, prior to signing this Agreement, it has asked such questions,
received such answers and obtained such information as it has deemed necessary or advisable to evaluate the merits and risks of
the purchase of the Shares and an investment in the Company. The Purchaser is not relying on any oral representation made by any
person as to the Company or its operations, financial condition or prospects.


 


(vii)       The
Purchaser understands that no federal, state or other governmental authority has made any recommendation, findings or determination
relating to the merits of an investment in the Company.


 


(viii)      The
Purchaser acknowledges that neither the Company, nor any of its officers, directors, employees, agents or affiliates has made any
representation or warranty, express or implied, regarding the Company, the Shares or otherwise, other than the representations
and warranties set forth herein.


 


(ix)         The
Purchaser acknowledges its obligations under the Securities Act, and the rules and regulations promulgated thereunder, with respect
to the treatment of non-public information relating to the Company.

(b)           Power
and Authority; Enforceability. This Agreement constitutes the legal, valid, and binding obligation of the Company, enforceable
against the Company in accordance with its terms. The Company has full power and authority to execute and deliver this Agreement
and to perform its obligations hereunder. The Company has taken all actions necessary to authorize the execution and delivery of
this Agreement, the performance of its obligations hereunder, and the consummation of the transactions contemplated hereby. This
Agreement has been duly authorized, executed, and delivered by the Company.


 


(c)           No
Violation; Necessary Approvals. Neither the execution and delivery of this Agreement by the Company, nor the consummation or
performance by the Company of any of the transactions contemplated hereby, will: (i) with or without notice or lapse of time,
constitute, create or result in a breach or violation of, default under, loss of benefit or right under, termination, cancellation,
suspension or modification of, or acceleration of performance of any obligation required under any (A) law (statutory, common or
otherwise), constitution, ordinance, rule, regulation, executive order or other similar authority enacted, adopted, promulgated

a party or by which it is bound (other than receipt of the Restated Certificate Approval); or (iv) require any Permit under
any Law or Order other than (A) required filings, if any, with the Securities and Exchange Commission and (B) notifications
or other filings with state or federal regulatory agencies after the Closing that are necessary or convenient and do not require

Law. This Agreement, the entire relationship of the parties hereto, and any litigation between the parties (whether grounded
in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the

The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect
the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to

Except as otherwise expressly provided in this Agreement or in the definitive documents for the Transaction, each party hereto
will bear its own costs and expenses incurred in connection with the preparation, execution and performance of this Agreement and
the consummation of the transactions contemplated hereby.

No waiver by either party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional
or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder
or affect in any way any rights arising because of any prior or subsequent occurrence.


 


(n)           Further
Assurances. The parties hereto shall execute and deliver such additional documents and take such additional actions as either
party reasonably may deem to be practical and necessary in order to consummate the purchase and sale of Common Stock as contemplated

(o)           Trust
Fund Waiver. Reference is made to the final prospectus of the Company dated October 24, 2013 (File No. 333-191195) (the “Prospectus”).
The Purchaser warrants and represents that it has read the Prospectus and understands that Company has established the Trust Fund
containing the proceeds of the IPO initially in the amount of at least Seventy-Two Million Seven Hundred Ninety-Five Thousand Dollars
($72,795,000) for the benefit of the Company’s public stockholders and certain other parties (including the underwriters
of the IPO) and that the Company may disburse monies from the Trust Fund, including any proceeds therefrom, only as provided in
the Prospectus. For and in consideration of the Company agreeing to enter into this Agreement, the Purchaser agrees that, notwithstanding
any provisions contained in this Agreement, the Purchaser does not now have, and shall not at any time prior to the Closing have,
any claim to, or make any claim against, the Trust Fund, any asset contained therein or any Additional Person, regardless of whether
such claim arises as a result of, in connection with or relating in any way to, the business relationship between STG or any of
its Subsidiaries, on the one hand, and the Company, on the other hand, this Agreement or any other agreement or any other matter,
and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability. The Purchaser
(for itself and on behalf of its Affiliates and direct and indirect subsidiaries and stockholders, and its and their respective
successors and assigns, and any Person claiming by or through the Purchaser) hereby irrevocably waives any and all rights, titles,
interests and claims of any kind that the Purchaser may have, now or in the future (in each case, however, prior to the consummation
of a business combination), and shall not take any action or suit, make any claim or demand or seek recovery of any Liability or
recourse against, the Trust Fund or any Additional Person for any reason whatsoever in respect thereof. The Purchaser agrees and
acknowledges that such irrevocable waiver is material to this Agreement and specifically relied upon by the Company to induce it
to enter into this Agreement. The Purchaser further intends and understands such waiver to be valid, binding and enforceable under
applicable Law. To the extent that the Purchaser commences any action or Proceeding based upon, in connection with, relating to
or arising out of any matter relating to the Company or any Additional Person, which Proceeding seeks, in whole or in part, monetary
relief against the Company or any Additional Person, the Purchaser hereby acknowledges and agrees that the Purchaser’s sole
remedy shall be against the Company’s funds held outside of the Trust Fund and that such claim shall not permit the Purchaser
(or any party claiming on the Purchaser’s behalf or in lieu of the Purchaser) to have any claim against any Additional Person
or the Trust Fund or any amounts contained therein. In the event that the Purchaser commences any action or Proceeding based upon,
in connection with, relating to or arising out of any matter relating to the Company or any Additional Person, which Proceeding
seeks, in whole or in part, relief against the Trust Fund, the Company’s public stockholders or any Additional Person, whether
in the form of money damages or injunctive relief, the Company shall be entitled to recover from the Purchaser the associated legal
fees and costs in connection with any such action, in the event the Company prevails in such action or Proceeding.
