authority may be made to the Company, and the Company shall forward such payment

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

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

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

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 $2,340,000;

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

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

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:

Attn: _______________

          Re: Trust Account No. [____________] Termination Letter

Gentlemen:

          Pursuant to Section 1(i) of the Investment Management Trust Agreement
between Vector Intersect Security Acquisition Corp. ("Company") and American
Stock Transfer & Trust Company ("Trustee"), dated as of __________, 2007 ("Trust
Agreement"), this is to advise you that the Company has entered into an
agreement ("Business Agreement") with __________________ ("Target Business") to
consummate a business combination with Target Business ("Business Combination")
on or about [insert date]. The Company shall notify you at least 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 the CRS have
been met,] and (ii) the Company and Rodman & Renshaw LLC, as representative of
the underwriters of the Company's IPO (the "Representative") shall deliver to
you joint written instructions with respect to the transfer of the funds held in
the Trust Account, including the Deferred Compensation ("Instructions"). You are
hereby directed and authorized to transfer the funds, including the Deferred
Compensation, held in the Trust Account immediately upon your receipt of the
counsel's letter, the Officer's Certificate and the Instructions, in accordance
with the terms of the Instructions. Notwithstanding 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 distributed as
follows: (1) first, to the Representative by wire transfer (or as 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 Instructions. In the
event that certain deposits held in the Trust Account may 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
Consummation Date described in the notice thereof and we have not notified you
on or before the original Consummation Date of a new Consummation Date, then the
funds held in the Trust Account shall be reinvested as

                             STOCK ESCROW AGREEMENT

          STOCK ESCROW AGREEMENT, dated as of ___________ ___, 2007
("Agreement") by and among Vector Intersect Security Acquisition Corp., a
Delaware corporation ("Company"), the undersigned parties listed as Initial
Stockholders on the signature page hereto (collectively, the "Initial
Stockholders") and American Stock Transfer & Trust Company as escrow agent (the
"Escrow Agent").

          WHEREAS, the Company has entered into an Underwriting Agreement, dated
_______ __, 2007 ("Underwriting Agreement") with Rodman & Renshaw, LLC, as
representative ("Rodman") of the underwriters named therein and with such other
underwriters (collectively, the "Underwriters") in connection with a public
offering (the "Public Offering") by the Company of Units (as hereafter defined),
pursuant to which, among other matters, the Underwriters have agreed to purchase
up to 8,409,375 units ("Units") of the Company, each consisting of one share of
the Company's Common Stock, par value $.001 per share (the "Common Stock"), and
one Warrant (a "Warrant"). Each Warrant evidences the right of the holder
thereof to purchase one share of Common Stock for $5.00, subject to adjustment,
as described in the Warrant Agreement dated as of _________, 2007 by and between
the Company and American Stock Transfer & Trust Company as Warrant Agent; and

          WHEREAS, the Company has entered into a Placement Unit Purchase
Agreement dated ____________, 2007 (the "Placement Agreement") pursuant to which
the Company has agreed to sell to Yaron Eitan, Winston Churchill and SCP Private
Equity Management Company LLC, 187,500 Units in a private placement to be
consummated concurrently with the Public Offering (the "Private Placement"); and

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

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

          NOW, THEREFORE, IT IS AGREED:

     1. Appointment of Escrow Agent. The Company and the Initial Stockholders
hereby appoint the Escrow Agent to act in accordance with and subject to the
terms of this Agreement and the Escrow Agent hereby accepts such appointment and
agrees to act in accordance with and subject to such terms.

     2. Deposit of Escrow Shares. Prior to the date of the consummation of the
Private Placement and the Public Offering, each of the Initial Stockholders
shall deliver to the Escrow Agent certificates representing his or her
respective Escrow Shares to be held and disbursed subject to the terms and
conditions of this Agreement. Each Initial Stockholder acknowledges

and agrees that the certificates representing his or her Escrow Shares will be
legended to reflect the deposit of such Escrow Shares under this Agreement.

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

     4. Rights of Initial Stockholders in Escrow Shares.

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

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

                                        2

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

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

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

     5. Concerning the Escrow Agent.

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

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

                                        3

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

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

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

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

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

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

     6. Miscellaneous.

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

                                        4

New York or the United States District Court for the Southern District of New
York (each, a "New York court"), and irrevocably submits to such jurisdiction,
which jurisdiction shall be exclusive. Each of the parties hereby waives any
objection to such exclusive jurisdiction and that such courts represent an
inconvenient forum. Each of ________________________,

(the "Authorized Agent") upon whom process may be served in any such action
arising out of or based on this Agreement or the transactions contemplated
hereby which may be instituted in any New York Court. Such appointment shall be
irrevocable. The Company and the Non-U.S. Initial Stockholders represent and
warrant that the Authorized Agent has agreed to act as such agent for service of
process and agrees to take any and all action, including the filing of any and
all documents and instruments that may be necessary to continue such appointment
in full force and effect as aforesaid. Service of process upon the Authorized
Agent and written notice of such service to the Company shall be deemed, in
every respect, effective service of process upon the respective Non-U.S. Initial
Stockholder.

          6.2. Third-Party Beneficiaries. Each of the Initial Shareholders
hereby acknowledges that Rodman is a third-party beneficiary of this Agreement
and this Agreement may not be modified or changed without the prior written
consent of Rodman.
