RECITALS

         A. Pledgor has agreed to deliver to Secured Party a certain  Promissory
Note made by  Pledgor  payable  to Secured  Party of even date  herewith  in the
principal  amount of Four Hundred  Thousand  Dollars  ($400,000) (the "NOTE") in
partial  payment of the  purchase  price of certain  shares of Class B Preferred
Stock of Pledgor, as provided in the Agreement and Mutual Release by and between
Pledgor and Secured Party dated as of January 8, 2007.

         B.  Pledgor  holds as treasury  stock  2,276,795  shares of its Class B
Preferred Stock (the "SHARES").

         C.  Pledgor  desires to grant to  Secured  Party a  perfected  security
interest  in the  Shares  pursuant  to and in  accordance  with  the  terms  and
provisions of this Pledge Agreement.

         NOW, THEREFORE,  for good and valuable  consideration,  the receipt and
adequacy of which are hereby acknowledged, the parties hereto agree as follows:

         1.  PLEDGE OF COLLATERAL. As collateral security for the payment of the
Note (the  "SECURED  OBLIGATIONS"),  Pledgor  hereby  grants to Secured  Party a
security  interest in and to the Shares,  together with all proceeds  therefrom,
including all payments,  interest,  profits, rights, including rights to payment
and  enforcement,  and all other property given in exchange or substitution  for
the Shares  (collectively,  the  "COLLATERAL").  Pledgor  shall take all actions
necessary  from time to time to  maintain  in favor of  Secured  Party the first
priority and  perfection of said pledge and security  interest at all times when
there exists any Secured  Obligations,  and Pledgor covenants and agrees that it
shall not take any actions that would alter,  impair, or eliminate said priority
or perfection.

         2.  DELIVERY   OF   CERTIFICATES   AND   INSTRUMENTS.  Pledgor   shall,
concurrently with the execution and delivery of this Pledge  Agreement,  deliver
to Secured  Party to be held by Secured  Party for so long as any of the Secured
Obligations remain due and owing:

             (a)   stock powers pertaining to the Shares in a form acceptable to
Secured Party; and

             (b)   the certificate evidencing the Shares.

         3.  EVENT OF  DEFAULT.  If  Pledgor  fails to pay the Note when due (an
"Event of Default"),  then, upon prior notice to Pledgor and at the sole expense
of Pledgor,  Secured Party,  in Secured  Party's name or in the name of Pledgor,
may, but shall not be obligated to, do any or all of the following: (a) exercise
any rights  relating to the  Collateral;  and (b) sell all or any portion of the
Collateral  and apply the sales  proceeds  thereof  (less the  normal  sales and
related


                                       1



charges  incurred in  connection  with that  action) in reduction of the Secured
Obligations; (c) collect by legal proceedings or otherwise, endorse, receive and
receipt for all  dividends  and other sums now or  hereafter  payable upon or on
account of the Collateral;  (d) make any compromise or settlement  Secured Party
deems desirable or proper with reference to the Collateral;  (e) insure, process
and preserve the Collateral;  (f) accept money or other property in exchange for
the Collateral, and take such action as Secured Party deems proper in connection
therewith,  and any other property received in exchange for the Collateral shall
be applied to the Secured  Obligations  or held by Secured  Party  thereafter as
Collateral  pursuant to the  provisions  hereof;  (g) cause the Collateral to be
transferred to Secured Party's name or to the name of Secured  Party's  nominee;
and (h) exercise as to the Collateral all the rights,  powers and remedies of an
owner necessary to exercise its rights under this Section.

        4. TAXES, CHARGES, ETC. Pledgor hereby agree to pay prior to delinquency
all taxes, charges, liens and assessments,  if any, assessed by any governmental
authority with respect to the Shares or against the other  Collateral  and, upon
the failure of Pledgor to do so, Secured Party at its option may pay any of them
and shall be the sole judge of the  legality or validity  thereof and the amount
necessary to discharge the same.

         5.  COSTS AND EXPENSES.  All reasonable  advances,  charges,  costs and
expenses,  including  reasonable  attorneys'  fees,  incurred or paid by Secured
Party  in  exercising  any  right,  power or  remedy  conferred  by this  Pledge
Agreement  or in the  enforcement  thereof  shall  become a part of the  Secured
Obligations  secured  hereunder  and shall be paid to  Secured  Party by Pledgor
immediately  and without demand,  with interest  thereon at the Default Rate, as
defined in the Note.

         6.  REMEDIES. Upon the occurrence of any Event of Default, upon written
notice to Pledgor, Secured Party may exercise as to any or all of the Collateral
all the rights, powers and remedies of an owner and of a secured party under the
Uniform  Commercial  Code of the  State  of  Nevada,  and may  elect to sell the
Collateral  in one or more  sales  after  giving a notice in  writing by mail to
Pledgor of such sale at least five (5) days before the date fixed for such sale.
The proceeds of any such sale shall be applied to: (a) the  reasonable  expenses
of retaking,  holding,  preparing for sale, selling and the like, and reasonable
attorneys'  fees and legal  expenses  incurred  by  Secured  Party,  and (b) the
Secured Obligations. Any surplus shall be paid to the person or persons entitled
thereto. Secured Party may bid and buy the Collateral at any public sale and, if
the Collateral is customarily  sold in a recognized  market or is the subject of
widely or regularly distributed standard price quotations, Secured Party may buy
at private  sale.  Any sale may be conducted by an  auctioneer or by an officer,
attorney or agent of Secured Party.

         So long as no Event of Default shall have  occurred and be  continuing,
the Pledgor  shall have the right to exercise all voting,  consensual  and other
powers of ownership  pertaining  to the  Collateral  for all  purposes;  and the
Secured Party shall, at the Pledgor' expense, execute and deliver to the Pledgor
or cause to be executed and delivered to the Pledgor all such proxies, powers of
attorney, dividend and other orders and other instruments,  without recourse, as
the Pledgor may  reasonably  request for the purpose of enabling  the Pledgor to
exercise the rights and powers which it is entitled to exercise pursuant to this
Section 6. So long as no Event of Default shall have occurred and be continuing,
the Pledgor  shall be  entitled  to receive and pledge  pursuant to the terms of
this Pledge Agreement any dividends and interest on the Collateral. If


                                       2



any Event of Default shall have occurred and be  continuing,  and whether or not
the  Secured  Party  exercises  any  available  right  to  declare  any  Secured
Obligation due and payable or seeks or pursues any other right, remedy, power or
privilege  available to it under  applicable law or this Pledge  Agreement,  all
dividends and other  distributions  on the Collateral  shall be paid directly to
the Secured Party and retained by it as part of the  Collateral,  subject to the
terms of this Pledge Agreement,  and, if the Secured Party shall so request, the
Pledgor jointly and severally agrees to execute and deliver to the Secured Party
appropriate  additional dividend,  distribution and other orders and instruments
to that end.

         The  Pledgor  recognizes  that,  by  reason  of  certain   prohibitions
contained in the Securities Act of 1933 and applicable  state  securities  laws,
the Secured Party may be compelled,  with respect to any sale of all or any part
of the  Collateral,  to limit  purchasers  to those who will agree,  among other
things, to acquire the Collateral for their own account,  for investment and not
with a view to distribution or resale.  The Pledgor  acknowledges  that any such
private sales may be at prices and on terms less  favorable to the Secured Party
than those  obtainable  through a public sale  without such  restrictions,  and,
notwithstanding  such circumstances,  agrees that any such private sale shall be
deemed  to have  been  made in a  commercially  reasonable  manner  and that the
Secured  Party  shall  have no  obligation  to  engage  in  public  sales and no
obligation to delay the sale of any  Collateral for the period of time necessary
to permit the  respective  Secured  Party of such  Collateral to register it for
public sale.

         7.   NO NOTICES.  Except as provided in this Pledge Agreement,  Secured
Party  shall be under no duty or  obligation  whatsoever  (a) to make or give to
Pledgor any  presentment,  demands for performance,  notices of  nonperformance,
protests,  notices of protest or notices of dishonor in  connection  with any of
the Collateral in which Secured Party has or claims a security interest,  or (b)
to give Pledgor  notice of, or to  exercise,  any rights or  privileges,  or any
rights or  privilege  to  exchange,  convert or redeem,  or any other  rights or
privileges relating to or affecting, any of the Collateral.

         8.  PLEDGOR LIABILITY.  Until the Secured  Obligations  shall have been
paid in full,  the  power of sale and all other  rights,  powers,  and  remedies
granted to Secured Party  hereunder shall continue to exist and may be exercised
by Secured Party at the time specified  hereunder  irrespective of the fact that
the  Secured  Obligations  or any part  thereof  may have  become  barred by any
statute of limitations or otherwise unenforceable,  or that the direct liability
of Pledgor may have ceased.

         9.   CUMULATIVE  REMEDIES.  The  rights,  powers, and remedies given to
Secured  Party by this  Pledge  Agreement  shall be in  addition  to all rights,
powers and remedies  given to Secured  Party by virtue of any statute or rule of
law. Any  forbearance  or failure or delay by Secured  Party in  exercising  any
right,  power or  remedy  hereunder  shall  not be deemed to be a waiver of such
right, power, or remedy, and any single or partial exercise of any right, power,
or remedy by Secured  Party  hereunder  shall not preclude the further  exercise
thereof,  and every right,  power, and remedy of Secured Party shall continue in
full force and effect until such right,  power or remedy is specifically  waived
by an instrument in writing executed by Secured Party.

         10.   MISCELLANEOUS.   This  Pledge  Agreement  shall  benefit  Secured
Party's  affiliates,  successors  and assigns and shall bind the  successors and
assigns of Pledgor. Unless otherwise



                                       3




defined,  words  used  herein  have  the  meanings  given  them  in the  Uniform
Commercial Code as adopted by the State of Nevada.  This Pledge  Agreement shall
be governed by Nevada law. Time is of the essence hereof.  This Pledge Agreement
contains the entire Pledge Agreement between Pledgor and Secured Party.  Pledgor
shall  execute all  documents and shall take all other actions from time to time
reasonably  required by Secured Party in order to maintain Secured Party's first
priority,  perfected  security  interest  in the  Collateral  and  otherwise  to
accomplish the purposes of this Pledge Agreement.  If any provision hereof shall
be held invalid,  such  invalidity  shall not affect the  enforceability  of any
other  provision  of this  Pledge  Agreement.  In the event  that any  action or
proceeding  is  instituted  to interpret or enforce the terms and  provisions of
this Pledge  Agreement,  the prevailing party shall be entitled to its costs and
reasonable  attorneys' fees, in addition to any other relief it may obtain or be
entitled to.

         IN WITNESS  WHEREOF,  Pledgor has executed this Pledge  Agreement as of
the date above written.
