certain Placement Unit Purchase Agreement dated ________, 2007 (the "Placement
Agreement") and (iii) 731,250 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
________, 2007, to purchase from the Company at a price of $8.00 per Unit less
underwriting discounts, up to an aggregate of 1,096,875 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) __________, 2008 and
terminating at 5:00 p.m., New York City time on the earlier to occur of (x)
__________, 2012 (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, securities 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
of the provisions of this Warrant Agreement.

     8.4 Liability of Warrant Agent.

          8.4.1 Reliance on Company Statement. Whenever in the performance of
its duties under this Warrant Agreement, the Warrant Agent shall deem it
necessary or desirable that any fact or matter be proved or established by the
Company prior to taking or suffering any action hereunder, such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively proved and established by a statement signed by the
Chief Executive Officer, Chairman of the Board or Chief Financial Officer of the
Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such

                                     WARRANT

THIS CERTIFIES THAT, for value received ________ is the registered holder of a
Warrant or Warrants expiring ________, 2012 (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 ______, 2007 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) __________,
2008, and terminating at 5:00 p.m., New York City time on the earlier to occur
of (x) ______, 2012 (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.

                                    WARRANT

THIS CERTIFIES THAT, for value received ________ is the registered holder of a
Warrant or Warrants expiring ________, 2012 (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 ______, 2007 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) __________,
2008, and terminating at 5:00 p.m., New York City time on the earlier to occur
of (x) ______, 2012 (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.

                                     A-3-2

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

Vector Intersect Security Acquisition Corp.
65 Challenger Road
Ridgefield Park, New Jersey 07660

Rodman & Renshaw LLC
1270 Avenue of the Americas
New York, NY 10020

          Re: Initial Public Offering

Gentlemen:

          The undersigned stockholder, officer and director of Vector Intersect
Security Acquisition Corp. ("Company"), in consideration of Rodman & Renshaw LLC
("Rodman") entering into an agreement to underwrite an initial public offering
of the securities of the Company ("IPO") and embarking on the IPO process,
hereby agrees as follows (certain capitalized terms used herein are defined in
paragraph 12 hereof):

          1. If the Company solicits approval of its stockholders of a Business
Combination, the undersigned will vote all Insider Shares and Placement Shares
owned by him and all shares of Common Stock of the Company acquired by him in
the IPO (the "IPO Shares") or aftermarket in favor of the Business Combination.
The undersigned will not exercise any statutory appraisal rights to which the
undersigned may be entitled under Section 262 of the Delaware General
Corporation Law (the "GCL") in connection with any Business Combination with
respect to any Insider Shares, Placement Shares, IPO Shares or shares acquired
in the aftermarket owned by him.

          2. In the event that the Company fails to consummate a Business
Combination within 18 months from the effective date ("Effective Date") of the
registration statement relating to the IPO or 24 months under the circumstances
described in the prospectus relating to the IPO (such later date being referred
to herein as the "Termination Date"), the undersigned shall (i) take all such
action reasonably within its power as is necessary to (a) dissolve the Company
and liquidate the Trust Fund to holders of IPO Shares as soon as reasonably
practicable, and after approval of the Company's stockholders and subject to the
requirements of the GCL, including voting for the adoption of a resolution by
the board of directors, prior to such Termination Date, pursuant to Section
275(a) of the GCL, which shall deem the dissolution of the Company advisable and
(b) cause to be prepared such notices as are required by said Section 275(a) of
the GCL as promptly thereafter as possible, and (ii) vote his shares in favor of
any plan of dissolution and distribution recommended by the Company's board of
directors. If the Company does not consummate a Business Combination by the
Termination Date, the

undersigned hereby agrees, with respect to any plan of dissolution and
distribution, to take all such action reasonably within its power to (x) cause
the board of directors to convene, adopt a plan of dissolution and distribution,
which the undersigned will vote to recommend to stockholders, and (y) on such
date cause the Company to prepare and file a proxy statement with the Securities
and Exchange Commission (the "SEC") setting out the plan of dissolution and
distribution. If the Company seeks approval from its stockholders to consummate
a Business Combination within 90 days of the expiration of 24 months from the
Effective Date, the undersigned agrees to take all such action reasonably within
its power to ensure that the proxy statement related to such Business
Combination will also seek stockholder approval for the plan of dissolution and
distribution in the event the stockholders do not approve the Business
Combination. If no proxy statement seeking the approval of the stockholders for
a Business Combination has been filed within 30 days prior to the date which is
24 months from the date of the IPO, the undersigned agrees, prior to such date
to take all such action reasonably within its power as is necessary to convene
and adopt a plan of dissolution and distribution and on such date file a proxy
statement with the SEC seeking stockholder approval for such plan. The
undersigned hereby waives any and all right, title, interest or claim of any
kind in or to any distribution of the Trust Fund and any remaining net assets of
the Company as a result of such liquidation with respect to all shares of Common
Stock then owned by him, including without limitation, his Insider Shares, his
Placement Shares, his IPO Shares and any shares acquired by him in the
aftermarket ("Claim") and hereby waives any Claim the undersigned may have in
the future as a result of, or arising out of, any contracts or agreements with
the Company and will not seek recourse against the Trust Fund for any reason
whatsoever. In the event of the liquidation of the Trust Fund, the undersigned
agrees to indemnify and hold harmless the Company against any and all loss,
liability, claims, damage and expense whatsoever (including, but not limited to,
any and all legal or other expenses reasonably incurred in investigating,
preparing or defending against any litigation, whether pending or threatened, or
any claim whatsoever) which the Company may become subject as a result of any
claim by any vendor, prospective target business or other entity that is owed
money by the Company for services rendered or products sold provided that the
Company did not obtain a valid and enforceable waiver from such party of its
rights or claims to the Trust Fund and only to the extent necessary to ensure
that such loss, liability, claim, damage or expense does not reduce the amount
in the Trust Fund. The foregoing section is not for the benefit of any third
party creditors of the Company.

          3. In order to minimize potential conflicts of interest which may
arise from multiple affiliations, the undersigned agrees to present to the
Company for its consideration, prior to presentation to any other person or
entity, any suitable opportunity to acquire a Target Business, until the earlier
of the consummation by the Company of a Business Combination, the liquidation of
the Company or until such time as the undersigned ceases to be an officer and
director of the Company, subject to any pre-existing fiduciary and contractual
obligations the undersigned might have.

          4. The undersigned acknowledges and agrees that the Company will not
consummate any Business Combination which involves a company which is affiliated

                                       2

with any of the Insiders.

          5. Neither the undersigned, any member of the family of the
undersigned, nor any affiliate ("Affiliate") of the undersigned will be entitled
to receive and will not accept any compensation for services rendered to the
Company prior to the consummation of the Business Combination except in
connection with bona fide services to be rendered to the Company that (i) are
