WARRANT AGREEMENT

      This Warrant  Agreement (this  "Agreement") made as of _________ __, 2005,
by and between Argyle Security Acquisition  Corporation,  a Delaware corporation
with  offices  at 200  Concord  Plaza,  Suite  700,  San  Antonio,  Texas  78216
("Company"), and American Stock Transfer & Trust Company, a New York corporation
with offices at 59 Maiden Lane, New York, New York 10038 ("Warrant Agent").

      WHEREAS,  the Company is engaged in a public offering ("Public  Offering")
of Units  ("Units")  and, in connection  therewith,  has determined to issue and
deliver up to 4,168,750  Warrants  ("Public  Warrants") to the public investors,
and (ii) 187,500 Warrants to Rodman & Renshaw,  LLC. ("Rodman") or its designees
("Underwriter's Warrants"), each of such Public Warrants evidencing the right of
the holder  thereof to purchase one share of common stock,  par value $.0001 per
share,  of the Company's  Common Stock  ("Common  Stock") for $5.50,  subject to
adjustment as described herein; and

      WHEREAS, the Company has filed with the Securities and Exchange Commission
(the "SEC") a Registration Statement,  No. 333-126569 on Form S-1 ("Registration
Statement")  for the  registration  under the Securities Act of 1933, as amended
("Act") of, among other  securities,  the Public Warrants and the  Underwriter's
Warrants and the Common Stock issuable upon exercise of the Public  Warrants and
the Underwriter's Warrants; and

      WHEREAS,  the Company is issuing 125,000  warrants in a private  placement
immediately  prior  to  the  Public  Offering,   which  warrants  (the  "Private
Warrants") will be identical to the Public 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  and  exercise of the
Public   Warrants,   the   Underwriter's   Warrants  and  the  Private  Warrants
(collectively, The "Warrants") 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,
shall be in substantially the form of Exhibit A hereto,  the provisions of which
are incorporated herein, and shall be signed by, or bear the facsimile signature


<PAGE>

of, the Chairman of the Board,  Vice Chairman or Co-Chief  Executive Officer and
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 securities  comprising the Units will
not be separately  transferable until 20 trading days after the earlier to occur
of the  expiration  of Rodman's  over-allotment  option or its  exercise in full
unless  Rodman  informs the Company of its  decision to allow  earlier  separate
trading,  but in no event will Rodman allow  separate  trading of the securities
comprising the Units until the Company files a Current Report on Form 8-K, which
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.

      2.5 Public Warrants and Underwriter's Warrants. The Underwriter's Warrants
shall have the same terms and be in the same form as the Public  Warrants except
with respect to the Warrant Price as set forth below in Section 3.1.

3. Terms and Exercise of Warrants.

            3.1 Warrant Price. Each Public Warrant shall, when  countersigned by
the  Warrant  Agent,  entitle  the  registered  holder  thereof,  subject to the
provisions  of such Public  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


                                       2
<PAGE>

hereof and in the last  sentence  of this  Section  3.1.  Each  Underwriter's
Warrant shall, when  countersigned by the Warrant Agent,  entitle the registered
holder thereof,  subject to the provisions of such Underwriter'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.

      3.2  Duration  of  Warrants.  A Warrant may be  exercised  only during the
period  ("Exercise  Period")  commencing on the later of the consummation by the
Company of a merger, capital stock exchange,  asset acquisition or other similar
business  combination  (as described more fully in the  Registration  Statement,
"Business  Combination")  or __________,  2006 and terminating at 5:00 p.m., New
York City time on the earlier to occur of  (i)__________,  2010 or (ii) the date
fixed for  redemption of the Warrants as provided in Section 6 of this Agreement
("Expiration Date").  Except with respect to the right to receive the Redemption
Price (as set forth in Section 6  hereunder),  each Warrant not  exercised on or
before 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 Expiration  Date. The Company in its sole  discretion may extend
the duration of the Warrants by delaying the Expiration Date.

      3.3 Exercise of Warrants.

            3.3.1  Payment.  Subject to the  provisions  of the Warrant 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 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 Warrant,  duly  executed,  and (i) by paying in full, in lawful
money of the United States,  in cash,  good  certified  check or good bank draft
payable to the order of the  Company,  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 or (ii) by
surrendering  his or her Warrant for that number of shares of Common Stock equal
to the quotient  obtained by dividing (x) the product of the number of shares of
Common Stock  underlying the Warrant,  multiplied by the difference  between the
Warrant Price and the "Fair Market Value" (defined below) by (y) the Fair Market
Value.  The "Fair Market Value" shall mean the average  reported last sale price
of the Common  Stock for the 10 trading  days ending on the third  business  day
prior to the date on which notice of exercise is given to the Company, or in the
event that the  Company has given a notice of  redemption  to the holder of such
Warrant,  on the third  business  day  prior to the date on which any  notice of
redemption is sent to holders of the Warrant pursuant to Section 6 hereof.

            3.3.2 Issuance of  Certificates.  As soon as  practicable  after the
exercise of any Warrant and 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


                                       3
<PAGE>

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 such exercise is effective, or (ii) in
the opinion of counsel to the  Company,  the  exercise of the Warrants is exempt
from the registration  requirements of the Act and such securities are qualified
for sale or exempt from  qualification  under applicable  securities laws of the
states or other  jurisdictions in which the registered holders 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.

            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 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.

            3.3.5 Warrant Solicitation and Warrant Solicitation Fee.

                  (a) The Company has engaged Rodman, on a non-exclusive  basis,
as its agent for the solicitation of the exercise of the Warrants.  The Company,
at its cost,  will (i)  assist  Rodman  with  respect to such  solicitation,  if
requested by Rodman,  and (ii) provide Rodman, and direct the Company's transfer
agent and the  Warrant  Agent to deliver to Rodman,  lists of the record and, to
the extent  known,  beneficial  owners of the  Company's  Warrants.  The Company
hereby  instructs the Warrant Agent to cooperate with Rodman in every respect in
connection with Rodman's solicitation activities, including, but not limited to,
providing to Rodman,  at the  Company's  cost,  a list of record and  beneficial
holders of the  Warrants  and  circulating  a  prospectus  or offering  circular
disclosing the compensation arrangements referenced in Section 3.3.5(b) below to
holders of the Warrants at the time of exercise of the Warrants.  In addition to
the conditions set forth in Section 3.3.5(b), Rodman shall accept payment of the
warrant  solicitation  fee provided in Section  3.3.5(b) only if it has provided
bona fide  services  to the  Company  in  connection  with the  exercise  of the
Warrants  and only to the extent that an investor  who  exercises  his  Warrants
specifically  designates,  in writing,  that Rodman  solicited  his,  her or its
exercise.  In addition to soliciting,  either orally or in writing, the exercise
of Warrants by a Warrant  holder,  such services may also include  disseminating
information,  either orally or in writing,  to Warrant holders about the Company
or the market for the Company's  securities,  or assisting in the  processing of
the exercise of Warrants.

                  (b) In each  instance  in which a Warrant  is  exercised,  the
Warrant Agent shall promptly give written notice of such exercise to the Company
and Rodman  ("Warrant  Agent's Exercise  Notice").  If, upon the exercise of any
Warrant  more  than  one  year  from  the  effective  date  of the  Registration


                                       4
<PAGE>

Statement,  (i) the market price of the  Company's  Common Stock is greater than
the Warrant Price,  (ii)  disclosure of  compensation  arrangements  between the
Company  and Rodman  with  respect to the  solicitation  of the  exercise of the
Warrants  was made both at the time of the  Public  Offering  and at the time of
exercise (by delivery of the  Prospectus or as otherwise  required by applicable
law, rule or  regulation),  (iii) the holder of the Warrant  confirms in writing
that the exercise of the Warrant was  solicited by Rodman,  (iv) the Warrant was
not held in a discretionary account, and (v) the solicitation of the exercise of
the Warrant was not in violation of  Regulation M (as such rule or any successor
rule  may be in  effect  as of such  time of  exercise)  promulgated  under  the
Securities   Exchange  Act  of  1934,  as  amended,   then  the  Warrant  Agent,
simultaneously with the distribution of the Common Stock underlying the Warrants
so exercised in  accordance  with the  instructions  from the Company  following
receipt  of  the  proceeds  to  the  Company  received  upon  exercise  of  such
Warrant(s),  shall,  on  behalf  of the  Company,  pay (A) in the case of a cash
exercise of the Warrant,  a fee of 5% of the Warrant Price to Rodman;  or (B) in
the case of  exercise of the  Warrant on a cashless  basis,  either a fee of .05
shares for each  warrant  exercised or 5% of the fair market value of each share
issued upon such exercise (the method of payment to be at the Company's option),
provided that Rodman delivers to the Warrant Agent within ten (10) business days
from the date on which Rodman has received the Warrant Agent's  Exercise Notice,
a certificate that the conditions set forth in the preceding clauses (iii), (iv)
and (v) have been satisfied.  Notwithstanding the foregoing, no fee will be paid
to Rodman with respect to the exercise by the  Underwriters or their  affiliates
or the Company's  officers or directors of Warrants  purchased by it or them and
still held by them for its or their own  account.  Rodman and the Company may at
any time during  business  hours,  examine  the  records of the  Warrant  Agent,
including its ledger of original  Warrant  certificates  returned to the Warrant
Agent upon exercise of Warrants.

                  (c) The provisions of this Section 3.3.5. may not be modified,
amended or deleted without the prior written consent of Rodman.

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 of shares of Common  Stock,  or other  similar  event,  then,  on the
effective date of such stock dividend,  split up 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 Exercise Price. Whenever the number of shares of Common
Stock purchasable upon the exercise of the Warrants is adjusted,  as provided in


                                       5
<PAGE>

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  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 Form of Warrant.  The form of Warrant  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


                                       6
<PAGE>

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
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  instructions for
transfer.  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 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 ("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


                                       7
<PAGE>

third business day prior to the date on which notice of redemption is given. The
provisions of this Section 6.1 may not be modified,  amended or deleted  without
the prior written consent of Rodman.

      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 for the
redemption.  Notice of redemption  shall be mailed by first class mail,  postage
prepaid,  by the  Company  not less  than 30 days  prior to the date  fixed  for
redemption  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 time and date fixed for redemption. 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.

      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 is 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 Rodman.

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

      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,  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
expiration  of the Warrants in  accordance  with the  provisions of this Warrant
Agreement.  The  provisions of this Section 7.4 may not be modified,  amended or
deleted without the prior written consent of Rodman.

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. Any successor  Warrant Agent,  whether
appointed by the Company or by such court, shall be a corporation  organized and
existing  under the laws of the State of New York,  in good  standing and 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.

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

Agent shall be a party shall be the  successor  Warrant Agent under this Warrant
Agreement without any further act.

forth on Exhibit A 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
Co-Chief  Executive  Officer,  Chairman  of the  Board or Vice  Chairman  of the
Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such
statement  for any action  taken or suffered in good faith by it pursuant to the
provisions of this Warrant Agreement.

            8.4.2  Indemnity.  The Warrant Agent shall be liable  hereunder only
for its own negligence,  willful  misconduct or bad faith. The Company agrees to
indemnify  the  Warrant  Agent  and  save  it  harmless   against  any  and  all
liabilities,  including  judgments,  costs  and  reasonable  counsel  fees,  for
anything  done or omitted by the Warrant  Agent in the execution of this Warrant
Agreement  except  as a  result  of  the  Warrant  Agent's  negligence,  willful
misconduct, or bad faith.

            8.4.3  Exclusions.  The Warrant  Agent shall have no  responsibility
with respect to the  validity of this  Warrant  Agreement or with respect to the
validity or execution of any Warrant (except its countersignature  thereof); nor
shall it be  responsible  for any  breach  by the  Company  of any  covenant  or
condition contained in this Warrant Agreement or in any Warrant; nor shall it be

responsible to make any  adjustments  required under the provisions of Section 4
hereof or responsible for the manner,  method,  or amount of any such adjustment
or the  ascertaining  of the  existence  of facts  that would  require  any such
adjustment;   nor  shall  it  by  any  act  hereunder  be  deemed  to  make  any
representation  or warranty as to the authorization or reservation of any shares
of Common Stock to be issued  pursuant to this Warrant  Agreement or any Warrant
or as to whether any shares of Common  Stock will when issued be valid and fully
paid and nonassessable.

      8.5  Acceptance  of Agency.  The Warrant  Agent hereby  accepts the agency
established  by this Warrant  Agreement  and agrees to perform the same upon the
terms and  conditions  herein set forth and among other  things,  shall  account
promptly to the Company  with  respect to Warrants  exercised  and  concurrently
account for, and pay to the Company,  all moneys  received by the Warrant  Agent
