certain Placement Unit Purchase Agreement dated ________, 2006 (the "Placement
Agreement") and (iii) 740,625 Warrants to Rodman & Renshaw LLC the
representative of the underwriters (the "Underwriters") with respect to the
Public Offering (the "Representative") or to the Representative's designees
("Representative's Warrants" and, together with the Public Warrants and the
Placement Warrants, the "Warrants"), each of such Warrants evidencing the right
of the holder thereof to purchase one share of common stock, par value $.001 per
share, of the Company's Common Stock ("Common Stock") for $5.00 in the case of
the Public Warrants and the Placement Warrants and $5.50 in the case of the
Representative's Warrants, subject to adjustment as described herein; and

      WHEREAS, the Company has filed with the Securities and Exchange Commission
(the "SEC") a Registration Statement, No. 333-127644 on Form S-1 (as may be
amended from time to time) ("Registration Statement") for the registration under
the Securities Act of 1933, as amended ("Act") of, among other securities, the
Public Warrants and the Representative's Warrants and the Common Stock issuable
upon exercise of the Public Warrants and the Representative's Warrants; and

      WHEREAS, the Company desires the Warrant Agent to act on behalf of the
Company, and the Warrant Agent is willing to so act, in connection with the
issuance, registration, transfer, exchange, redemption, exercise and
cancellation of the Warrants; and

      WHEREAS, the Company desires to provide for the form and provisions of the
Warrants, the terms upon which they shall be issued and exercised, and the
respective rights, limitation of rights, and immunities of the Company, the
Warrant Agent, and the holders of the Warrants; and

      WHEREAS, all acts and things have been done and performed which are
necessary to make the Warrants, when executed on behalf of the Company and
countersigned by or on behalf of the Warrant Agent, as provided herein, the
valid, binding and legal obligations of the Company, and to authorize the
execution and delivery of this Agreement.

      NOW, THEREFORE, in consideration of the mutual agreements herein
contained, the parties hereto agree as follows:

1.    Appointment of Warrant Agent. The Company hereby appoints the Warrant
Agent to act as agent for the Company for the Warrants, and the Warrant Agent
hereby accepts such appointment and agrees to perform the same in accordance
with the terms and conditions set forth in this Agreement.

2.    Warrants.

      2.1   Form of Warrant. Each Warrant shall be issued in registered form
only. Each Public Warrant, Placement Warrant and Representative Warrant shall be
in substantially the forms, respectively, of Exhibit A-1, Exhibit A-2 and
Exhibit A-3 hereto, the provisions of which are incorporated herein, and shall
be signed by, or bear the facsimile signature of, the Chairman of the Board or
Chief Executive Officer and Chief Financial Officer, Treasurer, Secretary or
Assistant Secretary of the Company and shall bear a facsimile of the Company's
seal. In the event the person whose facsimile signature has been placed upon any
Warrant shall have ceased to serve in the capacity in which such person signed
the Warrant before such Warrant is issued, it may be issued with the same effect
as if he or she had not ceased to be such at the date of issuance.

      2.2   Effect of Countersignature. Unless and until countersigned by the
Warrant Agent pursuant to this Agreement, a Warrant shall be invalid and of no
effect and may not be exercised by the holder thereof.

      2.3   Registration.

            2.3.1   Warrant Register. The Warrant Agent shall maintain books
("Warrant Register") for the registration of original issuance and the
registration of transfer of the Warrants. Upon the initial issuance of the
Warrants, the Warrant Agent shall issue and register the Warrants in the names
of the respective holders thereof in such denominations and otherwise in
accordance with instructions delivered to the Warrant Agent by the Company.

            2.3.2   Registered Holder. Prior to due presentment for registration
of transfer of any Warrant, the Company and the Warrant Agent may deem and treat
the person in whose name such Warrant shall be registered upon the Warrant
Register ("registered holder"), as the absolute owner of such Warrant and of
each Warrant represented thereby (notwithstanding any notation of ownership or
other writing on the Warrant Certificate made by anyone other than the Company
or the Warrant Agent), for the purpose of any exercise thereof, and for all
other purposes, and neither the Company nor the Warrant Agent shall be affected
by any notice to the contrary.

      2.4   Detachability of Warrants. The shares of Common Stock and Warrants
comprising the Units will not be separately transferable until the 20th trading
day following the earlier to occur of the expiration of the Underwriters'
Over-Allotment Option (as hereinafter defined) or the exercise in full by the
Underwriters of the Over-Allotment Option unless the Representative informs the
Company of its determination (based on its assessment of the relative strengths
of the securities markets and small capitalization companies in general and the
trading pattern of and demand for the Company's securities in particular) that
an earlier separate trading date is acceptable, but in no event will the
Representative allow separate trading of the securities

                                        2

comprising the Units until the Company files a Current Report on Form 8-K, that
includes an audited balance sheet reflecting the receipt by the Company of the
gross proceeds of the Public Offering including the proceeds received by the
Company from the exercise of the Underwriters' Over-Allotment Option, if the
Over-Allotment Option is exercised prior to the filing of the Form 8-K. For
purposes of this Warrant Agreement, the term "Over Allotment Option" shall mean
the option granted by the Company to the Underwriters, and exercisable until
________, 2006, to purchase from the Company at a price of $8.00 per Unit less
underwriting discounts, up to an aggregate of 1,110,938 Units for the sole
purpose of covering over-allotments, if any, in connection with the Public
Offering.

3.    Terms and Exercise of Warrants

      3.1   Warrant Price. Each Public Warrant and Placement Warrant shall, when
countersigned by the Warrant Agent, entitle the registered holder thereof,
subject to the provisions of such Public Warrant and Placement Warrant and of
this Warrant Agreement, to purchase from the Company the number of shares of
Common Stock stated therein, at the price of $5.00 per whole share, subject to
the adjustments provided in Section 4 hereof and in the last sentence of this
Section 3.1. Each Representative's Warrant shall, when countersigned by the
Warrant Agent, entitle the registered holder thereof, subject to the provisions
of such Representative's Warrant and of this Warrant Agreement, to purchase from
the Company the number of shares of Common Stock stated therein, at the price of
$5.50 per whole share, subject to the adjustments provided in Section 4 hereof
and in the last sentence of this Section 3.1. The term "Warrant Price" as used
in this Warrant Agreement refers to the price per share at which Common Stock
may be purchased at the time a Warrant is exercised. The Company in its sole
discretion may lower the Warrant Price at any time prior to the Expiration Date
(as hereinafter defined).

      3.2   Duration of Warrants. Subject to compliance with the terms set forth
in Section 3.3 hereof, a Warrant may be exercised only during the period
("Exercise Period") commencing on the later of (i) the date of consummation by
the Company of 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 (a "Business Combination") or (ii)
__________, 2007 and terminating at 5:00 p.m., New York City time on the earlier
to occur of (x) __________, 2011 (the "Expiration Date") or (y) the Redemption
Date (as hereinafter defined). Except with respect to the right, if applicable,
to receive the Redemption Price (as hereinafter defined), in the case of
Warrants called for redemption in accordance with Section 6 hereof) each Warrant
not exercised on or before the earlier of the Redemption Date or the Expiration
Date shall become void, and all rights thereunder and all rights in respect
thereof under this Agreement shall cease at the close of business on the earlier
of the Redemption Date or the Expiration Date. The Company in its sole
discretion may extend the duration of the Warrants by delaying the Expiration
Date. Notwithstanding the foregoing, a Warrant may expire unexercised regardless
of whether a registration statement covering the sale of the Common Stock
underlying the Warrants is effective. For purposes of this Warrant 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.

                                        3

      3.3   Exercise of Warrants.

            3.3.1   Payment. Subject to the provisions of the Warrants and this
Warrant Agreement, a Warrant, when countersigned by the Warrant Agent, may be
exercised by the registered holder thereof by surrendering it, at the office of
the Warrant Agent, or, if applicable, at the office of its successor as Warrant
Agent, in the Borough of Manhattan, City and State of New York, with the
subscription form, as set forth in the Warrants, duly executed, and by paying in
full, the Warrant Price for each full share of Common Stock as to which the
Warrant is exercised and any and all applicable taxes due in connection with the
exercise of the Warrant, the exchange of the Warrant for the Common Stock, and
the issuance of the Common Stock. Payment of the Warrant Price shall be made
either (i) in cash or by certified or official bank check payable to the order
of the Company or (ii) on a cashless basis by surrendering Warrants held by such
holder to the Company. Upon the surrender of Warrants to the Company in payment
of the Warrant Price, a holder shall be entitled to receive therefor that number
of shares of Common Stock otherwise issuable upon exercise of such holder's
Warrants less that number of shares of Common Stock having a Fair Market Value
(as hereinafter defined) equal to the aggregate Warrant Price that would
otherwise have been paid by the holder of such Warrants. For purposes of this
Section 3.3.1, the term "Fair Market Value" shall mean the average reported last
sales price of the Common Stock for the last 10 trading days ending on the third
business day prior to the date on which notice of redemption of the Warrants is
given by the Company.

            3.3.2   Issuance of Certificates. As soon as practicable after the
exercise of any Warrant and, to the extent applicable, the clearance of the
funds in payment of the Warrant Price, the Company shall issue to the registered
holder of such Warrant a certificate or certificates for the number of full
shares of Common Stock to which he, she or it is entitled, registered in such
name or names as may be directed by him, her or it, and if such Warrant shall
not have been exercised in full, a new countersigned Warrant for the number of
shares as to which such Warrant shall not have been exercised. Notwithstanding
the foregoing, the Company shall not be obligated to deliver any securities
pursuant to the exercise of a Warrant unless (i) a registration statement under
the Act with respect to the Common Stock issuable upon the exercise of such
Warrant is effective, or (ii) in the opinion of counsel to the Company, the
exercise of such Warrant is exempt from the registration requirements of the Act
and the shares of Common Stock issuable upon exercise of such Warrant are
qualified for sale or exempt from qualification under applicable securities laws
of the states or other jurisdictions in which the registered holder(s) thereof
reside. Warrants may not be exercised by, or securities issued to, any
registered holder in any state in which such exercise or issuance would be
unlawful. In no event will the registered holder of the Warrant be entitled to
receive a net-cash settlement, shares of Common Stock or other consideration in
lieu of physical settlement in shares of Common Stock, regardless of whether the
Common Stock underlying the Warrants is registered pursuant to an effective
registration statement.

            3.3.3   Valid Issuance. All shares of Common Stock issued upon the
proper exercise of a Warrant in conformity with this Agreement shall be validly
issued, fully paid and nonassessable.

            3.3.4   Date of Issuance. Each person in whose name any such
certificate for shares of Common Stock is issued shall for all purposes be
deemed to have become the holder of

                                        4

record of such shares on the date on which the Warrant was surrendered and
payment of the Warrant Price was made, irrespective of the date of delivery of
such certificate, except that, if the date of such surrender and payment is a
date when the stock transfer books of the Company are closed, such person shall
be deemed to have become the holder of such shares at the close of business on
the next succeeding date on which the stock transfer books are open.

4.    Adjustments.

      4.1   Stock Dividends/Split Ups. If after the date hereof, and subject to
the provisions of Section 4.6 below, the number of outstanding shares of Common
Stock is increased by a stock dividend payable in shares of Common Stock, or by
a split up or reclassification of shares of Common Stock, or other similar
event, then, on the effective date of such stock dividend, split up,
reclassification or similar event, the number of shares of Common Stock issuable
on exercise of each Warrant shall be increased in proportion to such increase in
outstanding shares of Common Stock.

      4.2   Aggregation of Shares. If after the date hereof, and subject to the
provisions of Section 4.6, the number of outstanding shares of Common Stock is
decreased by a consolidation, combination, reverse stock split or
reclassification of shares of Common Stock or other similar event, then, on the
effective date of such consolidation, combination, reverse stock split,
reclassification or similar event, the number of shares of Common Stock issuable
on exercise of each Warrant shall be decreased in proportion to such decrease in
outstanding shares of Common Stock.

      4.3   Adjustments in Warrant Price. Whenever the number of shares of
Common Stock purchasable upon the exercise of the Warrants is adjusted, as
provided in Section 4.1 and 4.2 above, the Warrant Price shall be adjusted (to
the nearest cent) by multiplying such Warrant Price immediately prior to such
adjustment by a fraction (x) the numerator of which shall be the number of
shares of Common Stock purchasable upon the exercise of the Warrants immediately
prior to such adjustment, and (y) the denominator of which shall be the number
of shares of Common Stock so purchasable immediately thereafter.

      4.4   Replacement of Securities upon Reorganization, etc. In case of any
reclassification or reorganization of the outstanding shares of Common Stock
(other than a change covered by Section 4.1 or 4.2 hereof or that solely affects
the par value of such shares of Common Stock), or in the case of any merger or
consolidation of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the continuing corporation and
that does not result in any reclassification or reorganization of the
outstanding shares of Common Stock), or in the case of any sale or conveyance to
another corporation or entity of the assets or other property of the Company as
an entirety or substantially as an entirety in connection with which the Company
is dissolved, the Warrant holders shall thereafter have the right to purchase
and receive, upon the basis and upon the terms and conditions specified in the
Warrants and in lieu of the shares of Common Stock of the Company immediately
theretofore purchasable and receivable upon the exercise of the rights
represented thereby, the kind and amount of shares of stock or other securities
or property (including cash) receivable upon such reclassification,
reorganization, merger or consolidation, or upon a dissolution following any
such sale or transfer, that the Warrant holder would have

                                        5

received if such Warrant holder had exercised his, her or its Warrant(s)
immediately prior to such event; and if any reclassification also results in a
change in shares of Common Stock covered by Section 4.1 or 4.2, then such
adjustment shall be made pursuant to Sections 4.1, 4.2, 4.3 and this Section
4.4. The provisions of this Section 4.4 shall similarly apply to successive
reclassifications, reorganizations, mergers or consolidations, sales or other
transfers.

      4.5   Notices of Changes in Warrant. Upon every adjustment of the Warrant
Price or the number of shares issuable on exercise of a Warrant, the Company
shall give written notice thereof to the Warrant Agent, which notice shall state
the Warrant Price resulting from such adjustment and the increase or decrease,
if any, in the number of shares purchasable at such price upon the exercise of a
Warrant, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Upon the occurrence of any event
specified in Sections 4.1, 4.2, 4.3 or 4.4, then, in any such event, the Company
shall give written notice to the Warrant holder, at the last address set forth
for such holder in the Warrant Register, of the record date or the effective
date of the event. Failure to give such notice, or any defect therein, shall not
affect the legality or validity of such event.

      4.6   No Fractional Shares. Notwithstanding any provision contained in
this Warrant Agreement to the contrary, the Company shall not issue fractional
shares upon exercise of Warrants. If, by reason of any adjustment made pursuant
to this Section 4, the holder of any Warrant would be entitled, upon the
exercise of such Warrant, to receive a fractional interest in a share, the
Company shall, upon such exercise, round up to the nearest whole number the
number of the shares of Common Stock to be issued to the Warrant holder.

      4.7   Forms of Warrants. The forms of the Public Warrants, the Placement
Warrants and the Representatives Warrants need not be changed because of any
adjustment pursuant to this Section 4, and Warrants issued after such adjustment
may state the same Warrant Price and the same number of shares as is stated in
the Warrants initially issued pursuant to this Agreement. However, the Company
may at any time in its sole discretion make any change in the form of any
Warrant that the Company may deem appropriate and that does not affect the
substance thereof, and any Warrant thereafter issued or countersigned, whether
in exchange or substitution for an outstanding Warrant or otherwise, may be in
the form as so changed.

5.    Transfer and Exchange of Warrants.

      5.1   Registration of Transfer. The Warrant Agent shall register the
transfer, from time to time, of any outstanding Warrant upon the Warrant
Register, upon surrender of such Warrant for transfer, properly endorsed with
signatures properly guaranteed and accompanied by appropriate instruction. Upon
any such transfer, a new Warrant representing an equal aggregate number of
Warrants shall be issued and the old Warrant shall be cancelled by the Warrant
Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the
Company from time to time upon request.

      5.2   Procedure for Surrender of Warrants. Warrants may be surrendered to
the Warrant Agent, together with a written request for exchange or transfer, and
thereupon the Warrant Agent shall issue in exchange therefor one or more new
Warrants as requested by the registered holder of the Warrants so surrendered,
representing an equal aggregate number of

                                        6

Warrants; provided, however, that in the event that a Warrant surrendered for
transfer bears a restrictive legend, the Warrant Agent shall not cancel such
Warrant and issue new Warrants in exchange therefor until the Warrant Agent has
received an opinion of counsel for the Company stating that such transfer may be
made and indicating whether the new Warrants must also bear a restrictive
legend.

      5.3   Fractional Warrants. The Warrant Agent shall not be required to
effect any registration of transfer or exchange which will result in the
issuance of a warrant certificate for a fraction of a warrant.

      5.4   Service Charges. No service charge shall be made for any exchange or
registration of transfer of Warrants.

      5.5   Warrant Execution and Countersignature. The Warrant Agent is hereby
authorized to countersign and to deliver, in accordance with the terms of this
Agreement, the Warrants required to be issued pursuant to the provisions of this
Section 5, and the Company, whenever required by the Warrant Agent, will supply
the Warrant Agent with Warrants duly executed on behalf of the Company for such
purpose.

6.    Redemption.

      6.1   Redemption. Subject to Section 6.4 hereof, not less than all of the
outstanding Warrants may be redeemed, at the option of the Company, at any time
after they become exercisable and prior to their expiration, at the office of
the Warrant Agent, upon the notice referred to in Section 6.2, at the price of
$.01 per Warrant (the "Redemption Price"), provided that the last sales price of
the Common Stock has been equal to or greater than $11.50 per share, on each of
twenty (20) trading days within any thirty (30) trading day period ending on the
third business day prior to the date on which notice of redemption is given.
Notwithstanding the foregoing, the registration statement with respect to the
shares of Common Stock for which the Warrants are exercisable must be current in
order for the Company to exercise its redemption rights pursuant to this Section
6. The provisions of this Section 6.1 may not be modified, amended or deleted
without the prior written consent of the Representative.

      6.2   Date Fixed for, and Notice of, Redemption. In the event the Company
shall elect to redeem all of the Warrants, the Company shall fix a date and time
for the redemption (the "Redemption Date"). Notice of redemption shall be mailed
by first class mail, postage prepaid, by the Company not less than 30 days prior
to the Redemption Date to the registered holders of the Warrants to be redeemed
at their last addresses as they shall appear on the Warrant Register. Any notice
mailed in the manner herein provided shall be conclusively presumed to have been
duly given whether or not the registered holder received such notice.

      6.3   Exercise After Notice of Redemption. The Warrants may be exercised
in accordance with Section 3 of this Warrant Agreement at any time after notice
of redemption shall have been given by the Company pursuant to Section 6.2
hereof and prior to the Redemption Date. On and after the Redemption Date, the
record holder of the Warrants shall have no further rights except to receive,
upon surrender of the Warrants, the Redemption Price.

                                        7

      6.4   Outstanding Warrants Only. The Company understands that the
redemption rights provided for by this Section 6 apply only to outstanding
Warrants. To the extent a person holds rights to purchase Warrants, such
purchase rights shall not be extinguished by redemption. However, once such
purchase rights are exercised, the Company may redeem the Warrants issued upon
such exercise provided that the criteria for redemption are met, including the
opportunity of the Warrant holder to exercise prior to redemption pursuant to
Section 6.3. The provisions of this Section 6.4 may not be modified, amended or
deleted without the prior written consent of the Representative.

7.    Other Provisions Relating to Rights of Holders of Warrants.

      7.1   No Rights as Stockholder. A Warrant does not entitle the registered
holder thereof to any of the rights of a stockholder of the Company, including,
without limitation, the right to receive dividends, or other distributions,
exercise any preemptive rights to vote or to consent or to receive notice as
stockholders in respect of the meetings of stockholders or the election of
directors of the Company or any other matter.

      7.2   Lost, Stolen, Mutilated, or Destroyed Warrants. If any Warrant is
lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on
such terms as to indemnity or otherwise as they may in their discretion impose
(which shall, in the case of a mutilated Warrant, include the surrender
thereof), issue a new Warrant of like denomination, tenor, and date as the
Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall
constitute a substitute contractual obligation of the Company, whether or not
the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time
enforceable by anyone.

      7.3   Reservation of Common Stock. The Company shall at all times reserve
and keep available a number of its authorized but unissued shares of Common
Stock that will be sufficient to permit the exercise in full of all outstanding
Warrants issued pursuant to this Warrant Agreement.

      7.4   Registration of Common Stock. The Company agrees that prior to the
commencement of the Exercise Period, it shall file with the SEC a post-effective
amendment to the Registration Statement, or a new registration statement, for
the registration, under the Act of the Common Stock issuable upon exercise of
the Warrants, and it shall take such action as is necessary to qualify for sale,
in those states in which the Warrants were initially offered by the Company, the
Common Stock issuable upon exercise of the Warrants. In either case, the Company
will use its best efforts to cause the same to become effective on or prior to
the commencement of the Exercise Period and to maintain the effectiveness of
such registration statement until the earlier of the Redemption Date or the
Expiration Date in accordance with the provisions of this Warrant Agreement. In
addition, the Company agrees to use its reasonable efforts to register such
securities under the blue sky laws of the states of residence of exercising
warrant holders, if permitted by the blue sky laws of such jurisdictions, in the
event that an exemption is not available. Notwithstanding the foregoing, a
Warrant may expire worthless regardless of whether a registration statement is
current under the Act with respect to the Common Stock issuable upon exercise of
the Warrants. In no event will the registered holder of a Warrant be entitled to
receive a net-cash settlement, shares of Common Stock or other consideration in
lieu of physical settlement in shares of Common Stock, regardless of whether

                                        8

the Company complies with this Section 7.4. The provisions of this Section 7.4
may not be modified, amended or deleted without the prior written consent of the
Representative.

8.    Concerning the Warrant Agent and Other Matters.

      8.1   Payment of Taxes. The Company will from time to time promptly pay
all taxes and charges that may be imposed upon the Company or the Warrant Agent
in respect of the issuance or delivery of shares of Common Stock upon the
exercise of Warrants, but the Company shall not be obligated to pay any transfer
taxes in respect of the Warrants or such shares.

      8.2   Resignation, Consolidation, or Merger of Warrant Agent.

            8.2.1   Appointment of Successor Warrant Agent. The Warrant Agent,
or any successor to it hereafter appointed, may resign its duties and be
discharged from all further duties and liabilities hereunder after giving sixty
(60) days' notice in writing to the Company. If the office of the Warrant Agent
becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint in writing a successor Warrant Agent in place of the Warrant
Agent. If the Company shall fail to make such appointment within a period of 30
days after it has been notified in writing of such resignation or incapacity by
the Warrant Agent or by the holder of the Warrant (who shall, with such notice,
submit his Warrant for inspection by the Company), then the holder of any
Warrant may apply to the Supreme Court of the State of New York for the County
of New York for the appointment of a successor Warrant Agent at the Company's
cost. Any successor Warrant Agent, whether appointed by the Company or by such
court, shall be a corporation having its principal office in the Borough of
Manhattan, City and State of New York, and authorized under such laws to
exercise corporate trust powers and subject to supervision or examination by
federal or state authority. After appointment, any successor Warrant Agent shall
be vested with all the authority, powers, rights, immunities, duties, and
obligations of its predecessor Warrant Agent with like effect as if originally
named as Warrant Agent hereunder, without any further act or deed; but if for
any reason it becomes necessary or appropriate, the predecessor Warrant Agent
shall execute and deliver, at the expense of the Company, an instrument
transferring to such successor Warrant Agent all the authority, powers, and
rights of such predecessor Warrant Agent hereunder; and upon request of any
successor Warrant Agent the Company shall make, execute, acknowledge, and
deliver any and all instruments in writing for more fully and effectually
vesting in and confirming to such successor Warrant Agent all such authority,
powers, rights, immunities, duties, and obligations.

            8.2.2   Notice of Successor Warrant Agent. In the event a successor
Warrant Agent shall be appointed, the Company shall give notice thereof to the
predecessor Warrant Agent and the transfer agent for the Common Stock not later
than the effective date of any such appointment.

            8.2.3   Merger or Consolidation of Warrant Agent. Any corporation
into which the Warrant Agent may be merged or with which it may be consolidated
or any corporation resulting from any merger or consolidation to which the
Warrant Agent shall be a party shall be the successor Warrant Agent under this
Warrant Agreement without any further act.

                                        9

      8.3   Fees and Expenses of Warrant Agent.

            8.3.1   Remuneration. The Company agrees to pay the Warrant Agent
reasonable remuneration for its services as such Warrant Agent hereunder as set
forth on Exhibit B hereto, and will reimburse the Warrant Agent upon demand for
all expenditures that the Warrant Agent may reasonably incur in the execution of
its duties hereunder.

            8.3.2   Further Assurances. The Company agrees to perform, execute,
acknowledge, and deliver or cause to be performed, executed, acknowledged, and
delivered all such further and other acts, instruments, and assurances as may
reasonably be required by the Warrant Agent for the carrying out or performing

"Warrant") to purchase one fully paid and non-assessable share of Common Stock,
par value $.001 per share ("Shares"), of VECTOR INTERSECT SECURITY ACQUISITION
CORP., a Delaware corporation (the "Company"), for each Warrant evidenced by
this Warrant Certificate. Subject to the conditions set forth herein and in the
Warrant Agreement dated as of ______, 2006 by and between the Company and the
Warrant Agent (the "Warrant Agreement"). The Warrant entitles the holder thereof
to purchase from the Company, commencing on the later of (i) the Company's
completion of a Business Combination with a Target Business or (ii) __________,
2007, and terminating at 5:00 p.m., New York City time on the earlier to occur
of (x) ______, 2011 (the "Expiration Date") or (y) the Redemption Date such
number of Shares of the Company at the price of $5.00 per share, upon surrender
of this Warrant Certificate and payment of the Warrant Price at the office or
agency of the Warrant Agent, American Stock Transfer & Trust Company. Payment of
the Warrant Price may be made at the option of the holder of the Warrant either
in cash or by certified or official bank check payable to the order of the
Company or on a cashless basis by surrendering Warrant's held by the holder to
the Company. The Warrant Agreement provides that upon the occurrence of certain
events the Warrant Price and the number of Warrant Shares purchasable hereunder,
set forth on the face hereof, may, subject to certain conditions, be adjusted.
The term Warrant Price as used in this Warrant Certificate refers to the price
per Share at which Shares may be purchased at the time the Warrant is exercised.
Capitalized terms used in this Warrant Certificate without definition shall have
the respective meanings ascribed to such terms in the Warrant Agreement.

      No fraction of a Share will be issued upon any exercise of a Warrant. If,
upon exercise of a Warrant, a holder would be entitled to receive a fractional
interest in a Share, the Company will, upon exercise, round up to the nearest
whole number the number of shares of common stock to be issued to the warrant
holder.

      Upon any exercise of the Warrant for less than the total number of full
Shares provided for herein, there shall be issued to the registered holder
hereof or his assignee a new Warrant Certificate covering the number of Shares
for which the Warrant has not been exercised.

      Warrant Certificates, when surrendered at the office or agency of the
Warrant Agent by the registered holder hereof in person or by attorney duly
authorized in writing, may be exchanged in the manner and subject to the
limitations provided in the Warrant Agreement, but without payment of any

                                      A-1-1

service charge, for another Warrant Certificate or Warrant Certificates of like
tenor and evidencing in the aggregate a like number of Warrants.

      Upon due presentment for registration of transfer of the Warrant
Certificate at the office or agency of the Warrant Agent, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee in
exchange for this Warrant Certificate, subject to the limitations provided in
the Warrant Agreement, without charge except for any applicable tax or other
governmental charge.

      The Company and the Warrant Agent may deem and treat the registered holder
as the absolute owner of this Warrant Certificate (notwithstanding any notation
of ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, of any distribution to the registered holder, and for all other
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice to the contrary.

      This Warrant does not entitle the registered holder to any of the rights
of a stockholder of the Company.

      The Company reserves the right to redeem all of the outstanding Warrants
at any time after they become exercisable and prior to the Expiration Date upon
a notice of redemption in writing to the holders of record of the Warrants,
giving no less than 30 days' notice of such redemption if the last sale price of
the Shares has been equal to or greater than $11.50 per Share on each of 20
trading days within a 30 trading day period ending on the third business day
prior to the date on which notice of such redemption is given. The redemption
price of the Warrants is to be $.01 per Warrant. Any Warrant either not
exercised or tendered back to the Company by the Redemption Date shall be
canceled on the books of the Company and have no further value except for the
$.01 redemption price.

      This Warrant Certificate shall not be valid or obligatory for any purpose
until it shall have been countersigned by the Warrant Agent.

canceled on the books of the Company and have no further value except for the
$.01 redemption price.

      This Warrant Certificate shall not be valid or obligatory for any purpose

                                     WARRANT

THIS CERTIFIES THAT, for value received

is the registered holder of a Warrant or Warrants expiring ________, 2011 (the
"Warrant") to purchase one fully paid and non-assessable share of Common Stock,
par value $.001 per share ("Shares"), of VECTOR INTERSECT SECURITY ACQUISITION
CORP., a Delaware corporation (the "Company"), for each Warrant evidenced by
this Warrant Certificate. Subject to the conditions set forth herein and in the
Warrant Agreement dated as of ______, 2006 by and between the Company and the
Warrant Agent (the "Warrant Agreement"), the Warrant entitles the holder thereof
to purchase from the Company, commencing on the later of (i) the Company's
completion of a Business Combination with a Target Business or (ii) __________,
2007, and terminating at 5:00 p.m., New York City time on the earlier to occur
of (x) ______, 2011 (the "Expiration Date") or (y) the Redemption Date such
number of Shares of the Company at the price of $5.50 per share, upon surrender
of this Warrant Certificate and payment of the Warrant Price at the office or
agency of the Warrant Agent, American Stock Transfer & Trust Company. Payment of
the Warrant Price may be made, at the option of the holder of the Warrant
either, in cash or by certified or official bank check payable to the order of
the Company or on a cashless basis by surrendering Warrants held by the holder
to the Company. The Warrant Agreement provides that upon the occurrence of
certain events the Warrant Price and the number of Warrant Shares purchasable
hereunder, set forth on the face hereof, may, subject to certain conditions, be
adjusted. The term Warrant Price as used in this Warrant Certificate refers to
the price per Share at which Shares may be purchased at the time the Warrant is
exercised. Capitalized terms used in this Warrant Certificate without definition
shall have the respective meanings ascribed to such terms in the Warrant
Agreement.

      No fraction of a Share will be issued upon any exercise of a Warrant. If,
upon exercise of a Warrant, a holder would be entitled to receive a fractional
interest in a Share, the Company will, upon exercise, round up to the nearest
whole number the number of shares of common stock to be issued to the warrant
holder.

      Upon any exercise of the Warrant for less than the total number of full
Shares provided for herein, there shall be issued to the registered holder
hereof or his assignee a new Warrant Certificate covering the number of Shares
for which the Warrant has not been exercised.

      Warrant Certificates, when surrendered at the office or agency of the
Warrant Agent by the registered holder hereof in person or by attorney duly
authorized in writing, may be exchanged in the manner and subject to the
limitations provided in the Warrant Agreement, but without payment of any

                                      A-3-1

service charge, for another Warrant Certificate or Warrant Certificates of like
tenor and evidencing in the aggregate a like number of Warrants.

      Upon due presentment for registration of transfer of the Warrant
Certificate at the office or agency of the Warrant Agent, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee in
exchange for this Warrant Certificate, subject to the limitations provided in
the Warrant Agreement, without charge except for any applicable tax or other
governmental charge.

      The Company and the Warrant Agent may deem and treat the registered holder
as the absolute owner of this Warrant Certificate (notwithstanding any notation
of ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, of any distribution to the registered holder, and for all other
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice to the contrary.

      This Warrant does not entitle the registered holder to any of the rights
of a stockholder of the Company.

      The Company reserves the right to redeem all of the outstanding Warrants
at any time after they become exercisable and prior to the Expiration Date upon
a notice of redemption in writing to the holders of record of the Warrants,
giving no less than 30 days' notice of such redemption if the last sale price of
the Shares has been equal to or greater than $11.50 per Share on each of 20
trading days within a 30 trading day period ending on the third business day
prior to the date on which notice of such redemption is given. The redemption
price of the Warrants is to be $.01 per Warrant. Any Warrant either not
exercised or tendered back to the Company by the Redemption Date shall be
canceled on the books of the Company and have no further value except for the
$.01 redemption price. Following the date on which notice of a redemption of the
Warrants has been given, payment of the Warrant Price may, at the option of the
holder thereof, also be made on a cashless basis by surrendering Warrants held
by such holder to the Company. Upon such surrender of Warrants to the Company in
payment of the Warrant Price, a holder shall be entitled to receive therefor
that number of Shares otherwise issuable upon exercise of such holder's Warrants
less the number of Shares having a Fair Market Value equal to the aggregate
Warrant Price that would otherwise have been paid by the holder of such
Warrants.

      This Warrant Certificate shall not be valid or obligatory for any purpose

which amount shall be paid directly to the taxing authority (and not through the

            (j)   Commence liquidation of the Trust Account only after receipt

therein. The Trustee understands and agrees that, except as provided in
paragraphs 1(i), 1(k) and 6(a) hereof,

disbursements from the Trust Account shall be made only pursuant to a duly
executed Termination Letter, together with the other documents referenced
herein. 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; and

            (k)   Upon one or more written requests from the Company, which may
be given not more than once in any calendar month period, the Trustee shall
distribute to the Company interest earned on the Trust Account, net of taxes
payable, up to a maximum of $1,500,000. The distributions requested by the
Company may be for any amount, provided that (i) in the aggregate, all
distributions under this Section 1(l) may not exceed $1,500,000 and (ii) that
such distributions may only be made if and to the extent that interest has been
earned on the amount initially deposited into the Trust Account; and

            (l)   Permit or effect no distribution from the Trust Account except
in accordance with Sections 1(i), 1(j), 1(k) and 5(b).

2.    Agreements and Covenants of the Company. The Company hereby agrees and
covenants to:

            (a)   Provide all instructions to the Trustee hereunder in writing,
signed by the Company's Chief Executive Officer, President, Chairman of the
Board or Chief Financial Officer. In addition, except with respect to its duties
under Section 1(i) above, the Trustee shall be entitled to rely on, and shall be
protected in relying on, any verbal or telephonic advice or instruction which it
in good faith believes to be given by any one of the persons authorized above to
give written instructions, provided that the Company shall promptly confirm such
instructions in writing;

            (b)   Hold the Trustee harmless and indemnify the Trustee from and
against any and all expenses, including reasonable counsel fees and
disbursements, or loss suffered by the Trustee in connection with any action,
suit or other proceeding brought against the Trustee involving any claim, or in
connection with any claim or demand which in any way arises out of or relates to
this Agreement, the services of the Trustee hereunder, or the Property or any
income earned from investment of the Property, except for expenses and losses
resulting from the Trustee's gross negligence or willful misconduct. Promptly
after the receipt by the Trustee of notice of demand or claim or the
commencement of any action, suit or proceeding, pursuant to which the Trustee
intends to seek indemnification under this paragraph, it shall notify the
Company in writing of such claim (hereinafter referred to as the "Indemnified
Claim"). The Trustee shall have the right to conduct and manage the defense
against such Indemnified Claim, provided, that the Trustee shall obtain the
consent of the Company with respect to the selection of counsel, which consent
shall not be unreasonably withheld. The Trustee may not agree to settle any
Indemnified Claim without the prior written consent of the Company. The Company
may participate in such action with its own counsel;

            (c)   Pay the Trustee an initial acceptance fee of $_______ and an
annual fee of $________ (it being expressly understood that the Property shall
not be used to pay such fee). The Company shall pay the Trustee the initial
acceptance fee and first year's fee at the consummation of the IPO and shall
thereafter pay the annual fee on the anniversary of the Effective Date. The
Trustee shall refund to the Company the fee (on a pro rata basis) with respect
to any period after the liquidation of the Trust Fund. The Company shall not be
responsible for any other fees or charges of the Trustee except as may be
provided in Section 2(b) hereof (it being expressly understood that the Property
shall not be used to make any payments to the Trustee under such Section);

            (d)   Within five business days after the Representative's
over-allotment option (or any unexercised portion thereof) expires or is
exercised in full, provide the Trustee notice in writing (with a copy to the
Representative) of the total amount of the Deferred Compensation, which shall in
no event be less than $2,370,000;

            (e)   Provide to the Trustee any letter of intent, agreement in
principle or definitive agreement that is executed in connection with a Business
Combination, together with a certified copy of a unanimous resolution of the
Board of Directors of the Company affirming that such letter of intent,
agreement in principle or definitive agreement is in effect; and

            (f)   In connection with any vote of the Company's stockholders
regarding a Business Combination, provide to the Trustee an affidavit or
certificate of a firm regularly engaged in the business of soliciting proxies
and tabulating stockholder votes verifying the vote of the Company's
stockholders and the Company's Public Stockholders regarding such Business
Combination.

3.    Limitations of Liability. The Trustee shall have no responsibility or
liability to:

            (a)   Take any action with respect to the Property, other than as
directed in Section 1 hereof and the Trustee shall have no liability to any
party except for liability arising out of its own gross negligence or willful
misconduct;

            (b)   Institute any proceeding for the collection of any principal
and income arising from, or institute, appear in or defend any proceeding of any
kind with respect to, any of the Property unless and until it shall have
received written instructions from the Company given as provided herein to do so
and the Company shall have advanced or guaranteed to it funds sufficient to pay
any expenses incident thereto;

            (c)   Change the investment of any Property, other than in
compliance with Section 1(c);

            (d)   Refund any depreciation in principal of any Property;

            (e)   Assume that the authority of any person designated by the
Company or the Representative to give instructions hereunder shall not be
continuing unless provided otherwise in such designation, or unless the Company
or the Representative shall have delivered a written revocation of such
authority to the Trustee;

            (f)   The other parties hereto or to anyone else for any action
taken or omitted by it, or any action suffered by it to be taken or omitted, in
good faith and in the exercise of its own best judgment, except for its gross
negligence or willful misconduct. The Trustee 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 Trustee), 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
Trustee, in good faith, to be genuine and to be signed or presented by the
proper person or persons. The Trustee shall not be bound by any notice or
demand, or any waiver, modification, termination or rescission of this Agreement
or any of the terms hereof, unless evidenced by a written instrument delivered
to the Trustee signed by the proper party or parties and, if the duties or
rights of the Trustee are affected, unless it shall give its prior written
consent thereto;

            (g)   Verify the correctness of the information set forth in the
Registration Statement or to confirm or assure that any acquisition made by the
Company or any other action taken by it is as contemplated by the Registration
Statement, unless an officer of the Trustee has actual knowledge thereof,
written notice of such event is sent to the Trustee or as otherwise required
under Section 1(j) hereof; and

            (h)   Pay any taxes on behalf of the Trust Account (it being
expressly understood that, as set forth in Section 1(i), if there is any income
tax obligation relating to the income of the Property in the Trust Account,
then, at the written instruction of the Company, the Trustee shall make
available in cash for transfer by account debit or wire transfer directly to the
taxing authorities designated by the Company, the amount indicated by the
Company as owing to each such taxing authority).

4.    Certain Rights Of Trustee.

            (a)   Before the Trustee acts or refrains from acting, it may
require an Officer's Certificate or opinion of counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on such Officer's Certificate or opinion of counsel. The Trustee may
consult with counsel and the advice of such counsel or any opinion of counsel
shall be full and complete authorization and protection from liability in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon.

            (b)   The Trustee may act through its attorneys and agents and shall
not be responsible for the misconduct or negligence of any agent appointed with
due care.

            (c)   The Trustee shall not be liable for any action it takes or
omits to take in good faith that it believes to be authorized or within the
rights or powers conferred upon it by this Agreement.

            (d)   The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Agreement; it shall not be
accountable for the Company's use of the proceeds from the Trust Account.
Notwithstanding the effective date of this Agreement or anything to the contrary
contained in this Agreement, the Trustee shall have no liability or
responsibility for any act or event relating to this Agreement or the
transactions related thereto which occurs prior to the date of this Agreement,
and shall have no contractual obligations to the Beneficiaries until the date of
this Agreement.

5.    No Right of Set-Off. The Trustee waives any right of set-off or any right,
title, interest or claim of any kind that the Trustee may have against the
Property held in the Trust Account. In the event that the Trustee has a claim
against the Company under this Agreement, including, without limitation, under
Section 3(b), the Trustee will pursue such claim solely against the Company and
not against the Property held in the Trust Account.

6.    Termination. This Agreement shall terminate as follows:

            (a)   If the Trustee gives written notice to the Company that it
desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee. At such time that the Company notifies
the Trustee that a successor trustee has been appointed by the Company and has
agreed to become subject to the terms of this Agreement, the Trustee shall
transfer the management of the Trust Account to the successor trustee, including
but not limited to the transfer of copies of the reports and statements relating
to the Trust Account, whereupon this Agreement shall terminate; provided,
however, that, in the event that the Company does not locate a successor trustee
within ninety days of receipt of the resignation notice from the Trustee, the
Trustee may submit an application to have the Property deposited with the United
States District Court for the Southern District of New York and upon

such deposit, the Trustee shall be immune from any liability whatsoever that
arises due to any actions or omissions to act by any party after such deposit;
or

            (b)   At such time that the Trustee has completed the liquidation of
the Trust Account in accordance with the provisions of Section 1(j) hereof, and
distributed the Property in accordance with the provisions of the Termination
Letter, this Agreement shall terminate except with respect to Section 2(b).

7.    Miscellaneous.

            (a)   The Company and the Trustee each acknowledge that the Trustee
will follow the security procedures set forth below with respect to funds
transferred from the Trust Account. Upon receipt of written instructions, the
Trustee will confirm such instructions with an Authorized Individual at an
Authorized Telephone Number listed on the attached Exhibit C. The Company and
the Trustee will each restrict access to confidential information relating to
such security procedures to authorized persons. Each party must notify the other
party immediately if it has reason to believe unauthorized persons may have
obtained access to such information, or of any change in its authorized
personnel. In executing funds transfers, the Trustee will rely upon account
numbers or other identifying numbers of a beneficiary, beneficiary's bank or
intermediary bank, rather than names. The Trustee shall not be liable for any
loss, liability or expense resulting from any error in an account number or
other identifying number, provided it has accurately transmitted the numbers
provided.

            (b)   This Agreement shall be governed by and construed and enforced
in accordance with the laws of the State of New York, without giving effect to
conflicts of law principles that would result in the application of the
substantive laws of another jurisdiction. It may be executed in several
counterparts, each one of which shall constitute an original, and together shall
constitute but one instrument.

            (c)   This Agreement contains the entire agreement and understanding
of the parties hereto with respect to the subject matter hereof. This Agreement
or any provision hereof may only be changed, amended or modified by a writing
signed by each of the parties hereto; provided, however, that no such change,
amendment or modification (other than to correct a typographical or similar
technical error) may be made to Sections 1(i), 1(j), 1(k) and 1(l) hereof
without the consent of the holders of 90% of the IPO Shares, it being the
specific intention of the parties hereto that each Public Stockholder is and
shall be a third-party beneficiary of this Section 7(c) with the same right and
power to enforce this Section 7(c) as either of the parties hereto. For purposes
of this Section 7(c), the "consent of the holders of 90% of the IPO Shares"
shall mean receipt by the Trustee of a certificate from an entity certifying
that (i) such entity regularly engages in the business of serving as inspector
of elections for companies whose securities are publicly traded, and (ii) either
(a) the holders of record of 90% of the IPO Shares of record as of a record date
established in accordance with Section 213(a) of the Delaware General
Corporation Law, as amended (the "DGCL"), have voted in favor of such amendment
or modification or (b) the holders of record of 90% of the IPO Shares of record
as of a record date established in accordance with Section 213(b) of the DGCL
have delivered to such entity a signed writing approving such amendment or
modification.

            (d)   As to any claim, cross-claim or counterclaim in any way
relating to this Agreement, each party waives the right to trial by jury.

            (e)   The parties hereto consent to the jurisdiction and venue of
any state or federal court located in the City of New York, Borough of
Manhattan, for purposes of resolving any disputes hereunder.

            (f)   Any notice, consent or request to be given in connection with
any of the terms or provisions of this Agreement shall be in writing and shall
be sent by express mail or similar private courier service, by certified mail
(return receipt requested), by hand delivery or by facsimile transmission:

48 hours in advance of the actual date of the consummation of the Business
Combination ("Consummation Date") and shall provide you with a certificate or
affidavit in accordance with Section 2(f) of the Trust Agreement. Capitalized
terms used herein and not otherwise defined shall have the meanings ascribed to
them in the Trust Agreement.

            In accordance with the terms of the Trust Agreement, we hereby
authorize you to commence liquidation of the Trust Account to the effect that,
on the Consummation Date, all of funds held in the Trust Account will be
immediately available for transfer to the account or accounts that the Company
shall direct on the Consummation Date.

            On the Consummation Date (i) counsel for the Company shall deliver
to you written notification that (a) the Business Combination has been
consummated and [(b) the provisions of Section 11-51-302(6) and Rule 51-3.4 of

including the Deferred Compensation, held in the Trust Account immediately upon

the foregoing, upon verification of receipt by you of the Instruction Letter, we
hereby agree and acknowledge that the Property in the Trust Account shall be

otherwise directed by the Representative) in immediately available funds, the
aggregate amount of $__________ plus any interest accrued thereon; and (2)
thereafter, to any other Beneficiary in accordance with the terms of the

not be liquidated by the Consummation Date without penalty, you will notify the
Company of the same and the Company, if the amount set forth in clause (1) shall
not have been paid in full, the Company and the Representative shall issue joint
written instructions directing you as to whether such funds should remain in the
Trust Account and distributed after the Consummation Date to the Company. Upon
the distribution of all the funds in the Trust Account pursuant to the terms
hereof, the Trust Agreement shall be terminated.

            In the event that the Business Combination is not consummated on the
