Re: Administrative Services Agreement

 

Gentlemen:

 

This letter will confirm
our agreement that, commencing on the effective date of the Registration Statement on Form S-1 and prospectus filed with the Securities
and Exchange Commission (the “Registration Statement”) by Global Defense & National Security Systems, Inc.
(the “Company”) (such date, the “Commencement Date”), and continuing until the earlier of
the consummation by the Company of an initial business combination or the distribution of the Trust Account (as defined below)
to the Company’s public stockholders (in each case as described in the Registration Statement) (such earlier date hereinafter
referred to as the “Termination Date”), Global Defense & National Security Holdings LLC (the “Sponsor”)
shall arrange for or make available to the Company, at a number of premises, including 11921 Freedom Drive, Suite 550, Two Fountain
Square, Reston, Virginia 20190 (or any successor location of the Sponsor), certain office space, utilities, and general office,
receptionist and secretarial support as may be reasonably required by the Company.  In exchange therefor, the Company
shall pay the Sponsor the sum of $10,000 per month on the Commencement Date and continuing monthly thereafter until the Termination
Date.

 

The Sponsor hereby irrevocably
waives any and all right, title, interest, causes of action and claims of any kind (each, a “Claim”) in or to,
and any and all right to seek payment of any amounts due to it out of, the trust account established for the benefit of the public
shareholders of the Company and into which substantially all of the proceeds of the Company’s initial public offering will
be deposited (the “Trust Account”), and hereby irrevocably waives any Claim it may have in the future as a result
of, or arising out of, this letter agreement, which Claim would reduce, encumber or otherwise adversely affect the Trust Account
or any monies or other assets in the Trust Account, and further agrees not to seek recourse, reimbursement, payment or satisfaction
of any Claim against the Trust Account or any monies or other assets in the Trust Account for any reason whatsoever.

 

This letter agreement
constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter and supersedes all prior
understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any
way to the subject matter hereof or the transactions contemplated hereby.

 

This letter agreement
may not be amended, modified or waived as to any particular provision, except by a written instrument executed by all parties hereto.

 

No party hereto may
assign either this letter agreement or any of its rights, interests, or obligations hereunder without the prior written approval
of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate
to transfer or assign any interest or title to the purported assignee.

 

This letter 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 laws of the State of New York,
without giving effect to its choice of laws principles.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF THE
BUYER

 

Buyer represents and warrants to the Company
that the statements contained in this ARTICLE III are correct and complete as of the date of this Agreement.

 

Section 3.1 Investment Representations.
In connection with the purchase of the Shares, Buyer represents to the Company the following:

 

(a) Buyer has been furnished
with all materials relating to the Company’s business affairs and financial condition and materials related to the offer
and sale of the Shares that have been requested by Buyer and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Shares. Buyer has been afforded the opportunity to ask questions of the executive
officer and directors of the Company. Buyer understands that its investment in the Shares involves a high degree of risk. Buyer
has sought such accounting, legal and tax advice as Buyer has considered necessary to make an informed investment decision with
respect to Buyer’s acquisition of the Shares. Buyer has such knowledge and expertise in financial and business matters, knows
of the high degree of risk associated with investments generally and particularly investments in the securities of companies in
the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Shares, and is
able to bear the economic risk of an investment in the Shares in the amount contemplated hereunder. Buyer has adequate means of
providing for its current financial needs and contingencies and will have no current or anticipated future needs for liquidity
which would be jeopardized by the investment in the Shares. Buyer is purchasing the Shares for investment for Buyer’s own
account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning
of the Securities Act. Buyer understands that the Company is a blank check development stage company recently formed for the purpose
of consummating the Business Combination and understands that there is no assurance as to the future performance of the Company
and that the Company may never effectuate the Business Combination.

 

(b) Buyer understands that the
Shares have not been registered under the Securities Act or any state securities law by reason of a specific exemption therefrom,
and that the Company is relying on the truth and accuracy of, and Buyer’s compliance with, the representations and warranties
and agreements of Buyer set forth herein to determine the availability of such exemptions and the eligibility of Buyer to acquire
such Shares, including, but not limited to, the bona fide nature of Buyer’s investment intent as expressed herein.

 

(c) Buyer further acknowledges
and understands that the Shares must be held indefinitely unless the Shares are subsequently registered under the Securities Act
or an exemption from such registration is available. Buyer understands that the certificates evidencing the Shares will be imprinted
with a legend which prohibits the transfer of the Shares (i) unless the Shares are registered or such registration is not required
in the opinion of counsel for the Company and (ii) until 30 days after the completion of the Business Combination.

 

(d) Buyer is familiar with the
provisions of Rule 144 under the Securities Act, as in effect from time to time (“Rule 144”), which,
in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer
thereof (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Unless
the Company registers the Shares under the Securities Act, the Shares may be resold by Buyer only in certain limited circumstances
subject to the provisions of Rule 144, which requires, among other things: (i) the availability of certain public information
about the Company and (ii) the resale occurring following the required holding period under Rule 144 after Buyer has purchased,
and made full payment of (within the meaning of Rule 144), the securities to be sold.

 

    	 

    	 

    

 

(e) Buyer further understands
that at the time Buyer wishes to sell the Shares there may be no public market upon which to make such a sale, and that, even if
such a public market then exists, the Company may not be satisfying the current public information requirements of Rule 144, and
that, in such event, Buyer would be precluded from selling the Shares under Rule 144 even if the minimum holding period requirement
had been satisfied. Notwithstanding Sections 3.1(d) and (e) hereof, Buyer understands that it may be considered a promoter
of the Company and understands that it is the position of the SEC that promoters or affiliates of a blank check company and their
transferees, both before and after the Business Combination, would act as an “underwriter” under the Act when reselling
the securities of a blank check company. Accordingly, the SEC believes that those securities can be resold only through a registered
offering and that Rule 144 would not be available for those resale transactions despite technical compliance with the requirements
of Rule 144.

 

(f) Buyer represents that Buyer
is an “accredited investor” as that term is defined in Rule 501 of Regulation D promulgated by the SEC under the Securities
Act.

 

(g) Buyer has all necessary
power and authority to enter into this Agreement and to consummate the transactions contemplated hereby. This Agreement has been
duly executed and delivered by Buyer. Subject to the terms and conditions of this Agreement, this Agreement constitutes the valid,
binding and enforceable obligation of Buyer, enforceable in accordance with its terms, except as enforceability may be limited
by (i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or similar laws of general application
now or hereafter in effect affecting the rights and remedies of creditors and by general principles of equity (regardless of whether
enforcement is sought in a proceeding at law or in equity); and (ii) the applicability of the federal and state securities
laws and public policy as to the enforceability of the indemnification provisions of this Agreement. The purchase by Buyer of the
Shares does not conflict with any material contract by which Buyer or its property is bound, or any laws or regulations or decree,
ruling or judgment of any court applicable to Buyer or its property. The principal place of business of Buyer is as set forth on
the signature page hereto.

 

(h) Buyer did not decide to
enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) of the
Securities Act.

 

ARTICLE IV

REPRESENTATIONS AND WARRANTIES OF THE
COMPANY

 

Section 4.1 Company Representations
and Warranties. The Company hereby represents and warrants to Buyer that the Company has all necessary corporate power and
authority to enter into this Agreement and to consummate the transactions contemplated hereby. All corporate action necessary to

has been duly executed and delivered by the Company. Subject to the terms and conditions of this Agreement, this Agreement constitutes
the valid, binding and enforceable obligation of the Company, enforceable in accordance with its terms, except as enforceability
may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or similar laws of
general application now or hereafter in effect affecting the rights and remedies of creditors and by general principles of equity
(regardless of whether enforcement is sought in a proceeding at law or in equity); and (ii) the applicability of the federal
and state securities laws and public policy as to the enforceability of the indemnification provisions of this Agreement. The sale
by the Company of the Shares does not conflict with the amended and restated certificate of incorporation or by-laws of the Company
or any material contract by which the Company or its property is bound, or any federal or state laws or regulations or decree,
ruling or judgment of any United States or state court applicable to the Company or its property.

 

Section 4.2 Power and Authority;
Enforceability. This Agreement constitutes the legal, valid, and binding obligation of the Company, enforceable against the

the performance of its obligations hereunder, and the consummation of the transactions contemplated hereby. This Agreement has
been duly authorized, executed, and delivered by, and is enforceable against, the Company.

 

Section 4.3 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 transactions contemplated hereby, will: (a) 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 or acceleration of performance of any obligation
required under any Law, Order, contract or Permit to which the Company is a party or by which it is bound or any of its assets
are subject, or any provision of the Company’s organizational documents as in effect on the Closing Date, (b) result
in the imposition of any Lien, claim or encumbrance upon any assets owned by the Company; (c) require any Consent under any
contract or organizational document to which the Company is a party or by which it is bound; or (d) require any Permit under
any Law or Order other than (i) required filings, if any, with the SEC and (ii) notifications or other filings with state
or federal regulatory agencies after the Closing that are necessary or convenient and do not require approval of the agency as
a condition to the validity of the transactions contemplated hereunder; or (e) trigger any rights of first refusal, preferential
purchase or similar rights with respect to any of the Shares.

ASSIGNMENT AND TRANSFER

 

Section 5.1 Assignment by Buyer.
Notwithstanding anything herein to the contrary, from the date hereof until the Closing Date, Buyer may assign to any of its affiliates
(collectively, the “Permitted Assignees”), the right to purchase any portion of the Shares (the “Assigned
Shares”). In the event of such an assignment, such Permitted Assignees will assume Buyer’s obligations under
this Agreement in regards to the Assigned Shares. Each Permitted Assignee will pay to the Company at the Closing an amount equal
to the product of the Per Share Price and the number of Assigned Shares to be purchased by such Permitted Assignee, and will be
bound by the restrictions imposed on the Assigned Shares by this Agreement, including the restrictions set forth in Section 5.2
hereof. Each Permitted Assignee will execute a counterpart signature page to this Agreement, agreeing to be bound by the provisions

Assigned Shares.
