                             STOCK ESCROW AGREEMENT

            STOCK ESCROW AGREEMENT, dated as of ___________ ___, 2006
("Agreement") by and among Vector Intersect Security Acquisition Corp., a
Delaware corporation ("Company"), the undersigned parties listed as Initial
Stockholders on the signature page hereto (collectively, the "Initial
Stockholders") and American Stock Transfer & Trust Company as escrow agent ( the
"Escrow Agent").

            WHEREAS, the Company has entered into an Underwriting Agreement,
dated _______ __, 2006 ("Underwriting Agreement") with Rodman & Renshaw, LLC, as
representative ("Rodman") of the underwriters named therein and with such other
underwriters (collectively, the "Underwriters") in connection with a public
offering (the "Public Offering") by the Company of Units (as hereafter defined),
pursuant to which, among other matters, the Underwriters have agreed to purchase
up to 8,517,188 units ("Units") of the Company, each consisting of one share of
the Company's Common Stock, par value $.001 per share (the "Common Stock"), and
one Warrant (a "Warrant"). Each Warrant evidences the right of the holder
thereof to purchase one share of Common Stock for $5.00, subject to adjustment,
as described in the Warrant Agreement dated as of _________, 2006 by and between
the Company and American Stock Transfer & Trust Company as Warrant Agent; and

            WHEREAS, the Company has entered into a Placement Unit Purchase
Agreement dated ____________, 2006 (the "Placement Agreement") pursuant to which
the Company has agreed to sell to Yaron Eitan, Winston Churchill and SCP Private
Equity Management Company LLC, 93,750 Units in a private placement to be
consummated concurrently with the Public Offering (the "Private Placement"); and

            WHEREAS, the Initial Stockholders have agreed, as a condition of the
Underwriters' obligation to purchase the Units pursuant to the Underwriting
Agreement and to offer them to the public, to deposit all of the shares of
Common Stock owned by them prior to the consummation of the Public Offering and
the Private Placement, which amounts are set forth opposite their respective
names in Schedule A attached hereto (collectively "Escrow Shares"), in escrow as
hereinafter provided; and

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

            NOW, THEREFORE, IT IS AGREED:

      1.    Appointment of Escrow Agent. The Company and the Initial
Stockholders 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 Escrow Shares. Prior to the date of the consummation of
the Private Placement and the Public Offering, each of the Initial Stockholders
shall deliver to the Escrow Agent certificates representing his or her
respective Escrow Shares to be held and disbursed




subject to the terms and conditions of this Agreement. Each Initial Stockholder
acknowledges and agrees that the certificates representing his or her Escrow
Shares will be legended to reflect the deposit of such Escrow Shares under this
Agreement.

      3.    Disbursement of the Escrow Shares. The Escrow Agent shall hold the
Escrow Shares until the earliest of (i) the date which is one year after the
date on which the Company consummates its initial Business Combination (as
hereinafter defined), (ii) the date on which any Business Combination
consummated by the Company results in a Change of Control (as hereinafter
defined) of the Company or (iii) the date on which the Company receives the
approval of the holders of not less than a majority of the outstanding shares of
the Company's Common Stock to a release of the Escrow Shares from the escrow
established in accordance with the terms of this Agreement ("Escrow Period").
Following the termination of the Escrow Period, the Escrow Agent shall, upon
written instructions from each Initial Stockholder, disburse each of the Initial
Stockholder's Escrow Shares to such Initial Stockholder; provided, however, that
if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof
that the Company is being liquidated at any time during the Escrow Period, then
the Escrow Agent shall promptly destroy the certificates representing the Escrow
Shares; provided further, that if, after the Company consummates a Business
Combination, it (or the surviving entity) subsequently consummates a
liquidation, merger, stock exchange or other similar transaction which results
in all of its stockholders of such entity having the right to exchange their
shares of Common Stock for cash, securities or other property, then the Escrow
Agent will, upon receipt of a certificate, executed by the Chairman, Chief
Executive Officer or Chief Financial Officer of the Company, in form reasonably
acceptable to the Escrow Agent, that such transaction is then being consummated,
release the Escrow Shares to the Initial Stockholders upon consummation of such
transaction so that they can similarly participate. The Escrow Agent shall have
no further duties hereunder after the disbursement or destruction of the Escrow
Shares in accordance with this Section 3. For purposes of this Agreement, the
term "Business Combination" shall mean a merger, capital stock exchange, asset
or stock acquisition or other similar business combination with one or more
Target Businesses (as hereinafter defined) having a fair market value of at
least 80% of the Company's net assets at the time of such acquisition. For
purposes of this Agreement, the term "Target Business" shall mean an operating
business based either in the United States or abroad that conducts business in
the homeland security, national security and/or command and control industries
or a business relating to the manufacture of products for use in such
industries. For purposes of this Agreement, the term "Change of Control" shall
mean a consolidation or merger involving the Company where the stockholders at
the Company immediately prior to such transaction hold less than 50% of the
voting stock of the surviving entity.

      4.    Rights of Initial Stockholders in Escrow Shares.

            4.1.  Voting Rights as a Stockholder. Subject to the terms of the
Insider Letter described in Section 4.4 hereof and except as herein provided,
the Initial Stockholders shall retain all of their rights as stockholders of the
Company during the Escrow Period, including, without limitation, the right to
vote such shares.

            4.2.  Dividends and Other Distributions in Respect of the Escrow
Shares. During the Escrow Period, all dividends payable in cash with respect to
the Escrow Shares shall


                                        2



be paid to the Initial Stockholders, but all dividends payable in stock or other
non-cash property ("Non-Cash Dividends") shall be delivered to the Escrow Agent
to hold in accordance with the terms hereof. As used herein, the term "Escrow
Shares" shall be deemed to include the Non-Cash Dividends distributed thereon,
if any.

            4.3.  Restrictions on Transfer. During the Escrow Period, no sale,
transfer or other disposition may be made of any or all of the Escrow Shares
except (i) by gift to a member of Initial Stockholder's immediate family or to a
trust or other entity, the beneficiary of which is an Initial Stockholder or a
member of an Initial Stockholder's immediate family, or (ii) by virtue of the
laws of descent and distribution upon death of any Initial Stockholder, (iii)
pursuant to a qualified domestic relations order; provided, however, that such
permissive transfers may be implemented only upon the respective transferee's
written agreement to be bound by the terms and conditions of this Agreement and
of the Insider Letter signed by the Initial Stockholder transferring the Escrow
Shares. During the Escrow Period, no Initial Stockholder shall pledge or grant a
security interest in his, her or its Escrow Shares or grant a security interest
in his, her or its rights under this Agreement.

            4.4.  Insider Letters. Each of the Initial Stockholders has executed
a letter agreement with Rodman and the Company, dated as indicated on Schedule A
hereto ("Insider Letter"), and which is filed as an exhibit to the Company's
Registration Statement on Form S-1, Registration No. 333-127644 with respect to
the Units to be issued in the Public Offering (the "Registration Statement"),
respecting the rights and obligations of such Initial Stockholder in certain
events, including but not limited to the liquidation of the Company.

      5.    Concerning the Escrow Agent.

            5.1.  Good Faith Reliance. The Escrow Agent shall not be liable for
any action taken or omitted by it in good faith and in the exercise of its own
best judgment, and may rely conclusively and shall be protected in acting upon
any order, notice, demand, certificate, opinion or advice of counsel (including
counsel chosen by the Escrow Agent), statement, instrument, report or other
paper or document (not only as to its due execution and the validity and
effectiveness of its provisions, but also as to the truth and acceptability of
any information therein contained) which is believed by the Escrow Agent to be
genuine and to be signed or presented by the proper person or persons. The
Escrow Agent shall not be bound by any notice or demand, or any waiver,
modification, termination or rescission of this Agreement unless evidenced by a
writing delivered to the Escrow Agent signed by the proper party or parties and,
if the duties or rights of the Escrow Agent are affected, unless it shall have
given its prior written consent thereto.

            5.2.  Indemnification. The Escrow Agent shall be indemnified and
held harmless by the Company from and against any expenses, including counsel
fees and disbursements, or loss suffered by the Escrow Agent in connection with
any action, suit or other proceeding involving any claim which in any way,
directly or indirectly, arises out of or relates to this Agreement, the services
of the Escrow Agent hereunder, or the Escrow Shares held by it hereunder, other
than expenses or losses arising from the gross negligence or willful misconduct
of the Escrow Agent. Promptly after the receipt by the Escrow Agent of notice of
any demand or claim or the commencement of any action, suit or proceeding, the
Escrow Agent shall notify the


                                        3



other parties hereto in writing. In the event of the receipt of such notice, the
Escrow Agent, in its sole discretion, may commence an action in the nature of
interpleader in an appropriate court to determine ownership or disposition of
the Escrow Shares or it may deposit the Escrow Shares with the clerk of any
appropriate court or it may retain the Escrow Shares pending receipt of a final,
non appealable order of a court having jurisdiction over all of the parties
hereto directing to whom and under what circumstances the Escrow Shares are to
be disbursed and delivered. The provisions of this Section 5.2 shall survive in
the event the Escrow Agent resigns or is discharged pursuant to Sections 5.5 or
5.6 below.

            5.3.  Compensation. The Escrow Agent shall be entitled to reasonable
compensation from the Company for all services rendered by it hereunder, as set
forth on Exhibit A hereto. The Escrow Agent shall also be entitled to
reimbursement from the Company for all expenses paid or incurred by it in the
administration of its duties hereunder including, but not limited to, all
counsel, advisors' and agents' fees and disbursements and all taxes or other
governmental charges.

            5.4.  Further Assurances. From time to time on and after the date
hereof, the Company and the Initial Stockholders shall deliver or cause to be
delivered to the Escrow Agent such further documents and instruments and shall
do or cause to be done such further acts as the Escrow Agent shall reasonably
request to carry out more effectively the provisions and purposes of this
Agreement, to evidence compliance herewith or to assure itself that it is
protected in acting hereunder.

            5.5.  Resignation. The Escrow Agent may resign at any time and be
discharged from its duties as escrow agent hereunder by its giving the other
parties hereto written notice and such resignation shall become effective as
hereinafter provided. Such resignation shall become effective at such time that
the Escrow Agent shall turn over to a successor escrow agent appointed by the
Company and approved by Rodman, the Escrow Shares held hereunder. If no new
escrow agent is so appointed within the 60 day period following the giving of
such notice of resignation, the Escrow Agent may deposit the Escrow Shares with
any court it deems appropriate.

            5.6.  Discharge of Escrow Agent. The Escrow Agent shall resign and
be discharged from its duties as escrow agent hereunder if so requested in
writing at any time by the Company and a majority of the Initial Stockholders,
jointly, provided, however, that such resignation shall become effective only
upon acceptance of appointment by a successor escrow agent as provided in
Section 5.5.

            5.7.  Liability. Notwithstanding anything herein to the contrary,
the Escrow Agent shall not be relieved from liability hereunder for its own
gross negligence or its own willful misconduct.

      6.    Miscellaneous.

            6.1.  Governing Law. This Agreement shall for all purposes be deemed
to be made under and shall be construed in accordance with the laws of the State
of New York. Each of the parties hereby agrees that any action, proceeding or
claim against it arising out of or


                                        4



relating in any way to this Agreement shall be brought and enforced in the
courts of the State of New York or the United States District Court for the
Southern District of New York (each, a "New York court"), and irrevocably
submits to such jurisdiction, which jurisdiction shall be exclusive. Each of the
parties hereby waives any objection to such exclusive jurisdiction and that such
courts represent an inconvenient forum. [Each of ________________________,
___________________________ and _____________________ (together, the "Non-U.S.
Initial Stockholders") has appointed ________________ as its authorized agent
(the "Authorized Agent") upon whom process may be served in any such action
arising out of or based on this Agreement or the transactions contemplated
hereby which may be instituted in any New York Court. Such appointment shall be
irrevocable. The Company and the Non-U.S. Initial Stockholders represent and
warrant that the Authorized Agent has agreed to act as such agent for service of
process and agrees to take any and all action, including the filing of any and
all documents and instruments that may be necessary to continue such appointment
in full force and effect as aforesaid. Service of process upon the Authorized
Agent and written notice of such service to the Company shall be deemed, in
every respect, effective service of process upon the respective Non-U.S. Initial
Stockholder.]

            6.2.  Third-Party Beneficiaries. Each of the Initial Shareholders
hereby acknowledges that Rodman is a third-party beneficiary of this Agreement
