                      (TRADEARK MEMBERSHIP INTEREST PLEDGE)

         WHEREAS,  CAPITOL  DEVELOPMENT OF ARKANSAS,  INC. ("CDA"),  an Arkansas

(hereinafter  referred to as the "Pledgor") has borrowed or has agreed to borrow

(hereinafter  referred to as  "Pledgee")  the  principal sum of FOUR MILLION AND

         WHEREAS,  Pledgor  is the  owner of a  35.16%  membership  interest  in
TradeArk Properties, LLC ("TradeArk"), a Michigan limited liability company

         WHEREAS,  the Pledgor has executed a promissory note on April 26, 2002,
and has  agreed to  execute  and to deliver  to the  Pledgee a  promissory  note
modification,  hereinafter referred to as the "Modified Note", for the principal
amount of FOUR MILLION and  NO/100ths  DOLLARS  ($4,000,000.00)  to evidence the
indebtedness arising in connection with the aforesaid loan made or to be made by
Pledgee to Pledgor; and

         WHEREAS,  the Pledgor  became a member of TradeArk and  executed,  as a
member, an operating  agreement for the Company dated May 27, 1999.  Pledgor has
agreed to  pledge to  Pledgee  CDA's  35.16%  membership  interest  in  TradeArk
(hereinafter  referred to as "TradeArk  Interest")  as security for the Modified
Note;

         NOW,  THEREFORE,  in consideration of the premises and as an inducement
to the Pledgee to lend the  principal  sum of FOUR  MILLION and NO/100s  DOLLARS
($4,000,000.00) to Pledgor and in consideration thereof, the Pledgor does hereby
assign,  transfer,  set over and pledge to Pledgee the TradeArk Interest and the
Pledgee and the Pledgor hereby agree as follows:

         1.   Purpose of Pledge.  This Pledge is made as collateral security for
the repayment,  according to its terms,  of the full amount of the Modified Note
including interest thereon.

         2.   Possession of the Pledged TradeArk Interest.  Pledgor shall assign
and  transfer  the  TradeArk  Interest  immediately  upon the  execution of this
Pledge,  and deliver to the escrow  agent named in the Modified  Note,  free and
clear of all liens and  encumbrances  and assigned to Pledgee.  Pledgee shall be
entitled to receive and have  delivered  to it, any  payments,  disbursed by the
TradeArk  Interest,  with any such payments made hereunder  applied first to the
interest  accruing upon the terms of the Note and Business Loan  Agreement,  and
any amendments thereof, next to charges,  costs, or expenses then due under this
Security  Agreement  or any other loan  documents  and the  balance,  if any, to
principal. Notwithstanding,  Pledgee agrees that Pledgor may sell and assign its
TradeArk  Interest and substitute other collateral equal to such interest,  upon
the approval of Pledgee, which shall not be unreasonably withheld.





         3.   Event of Default and Remedies.  If any one of the following events
(herein called "Event of Default") shall occur and be continuing:

              (a) If the Pledgor defaults in the  payment of any  installment of
the Note when the same shall have become due,  either by the terms  thereof,  or
otherwise, as herein provided and such default continues beyond any grace period
provided in the Note; or

              (b) If the Pledgor becomes in  default  under the  loan  agreement
governing the loan represented by the Note; or

              (c) If the Corporation or the Pledgor become in default  under any
mortgage, security agreement or other document or instrument given to provide or
create collateral security for the Note;

              then the Pledged TradeArk Interest,  which shall  at the  time  of
receipt thereof be applied to payment of the Note, may be sold,  transferred and
delivered  in whole or in part,  together  with  any  substitutes  therefor,  or
additions  thereto,  at any public or private sale, for cash,  upon credit,  for
present or future  delivery,  all at the option of Pledgee  upon  Pledgee's  (i)
declaring the Modified Note due and payable under the terms hereof, or declaring
other liability mentioned or referred to in this Pledge as being outstanding and
overdue, and (ii) giving not less than ten (10) days written notice of such sale
to Pledgor by personal delivery, or registered or certified mail, return receipt
requested,  addressed  to their last known  address.  All rights and remedies of
Pledgee upon an Event of Default,  including  any sale,  transfer or delivery of
the Pledged TradeArk Interest, shall occur in Palm Beach County, Florida.

         5.    Notice of Default.  The Pledgee shall deliver to Pledgor promptly
upon  the  occurrence  of any  Event  of  Default,  a  written  notice  thereof,
specifying the nature thereof but failure to promptly  deliver such notice shall
not constitute a waiver of any rights of Pledgee under this Agreement. A written
notice from  Pledgee to any  nominee  that an Event of Default  exists  shall be
sufficient evidence of that fact to such nominee.

         6.   Sale  of  Pledged  TradeArk Interest  by  Pledgee.  Any  sale,  as
provided herein,  of the TradeArk  Interest by Pledgee,  or its nominee,  may be
adjourned from time to time, if a public sale, by  announcement  at the time and
place appointed for any such sale, and without further notice,  such sale may be
made at the time  and  place to which  the same  shall be so  adjourned,  unless
otherwise provided by law. At such sale, Pledgee, or its nominee, shall be under
no duty to sell all of the  Pledged  TradeArk  Interest on the date fixed in the
notice, but beginning on such date, Pledgee,  or its nominee,  may sell the same
from day to day  until  all,  or a  portion  thereof,  have been sold to pay all
amounts  secured  by this  Pledge.  At any  such  sale,  Pledgee,  or any of its
employees  or  assigns,  as the  case  may be or its  nominee,  may  become  the
purchaser of the whole, or any part, of the Pledged TradeArk Interest, free from
any  trust,  claim,  right or equity of  redemption  of the  Pledgor,  which are
expressly  waived and  released.  In case of any sale on  credit,  or for future
delivery,  the Pledged TradeArk Interest sold may be retained by the Pledgee, or
its nominee,  until the selling price is paid by the purchaser,  but neither the
Pledgee,  nor its nominee,  shall incur any  liability in case of failure of the
purchaser to take up and pay for the Pledged TradeArk Interest so sold. Upon the
sale of any TradeArk Interest hereunder,  after deducting all costs and expenses
of collection,  Pledgee, or its nominee, shall apply the residue of the proceeds
of the sale, or sales, so made first to the payment of any sums Pledgee may pay,

                                       2
                         Collateral Security Agreement


or incur, in enforcing its rights under the Note and/or this Pledge,  and second
to the payment of any sums the Pledgor may be, or become liable to pay under any
of those  instruments,  and shall pay the  excess,  if any, to the  Pledgor.  No
purchaser at such sale, or sales, except the Pledgee,  or its nominee,  shall be
responsible for the application of the purchase money.

         7.   Waiver.  The Pledgor  agrees  that neither  the  Pledgee,  nor its
nominee,  shall be held liable for loss or damage  resulting from acts or events
beyond the reasonable  control of the Pledgee,  or its nominee,  and acts of the
Pledgee  taken in good  faith.  In taking,  or  refraining  from  taking  action
required,  or permitted,  hereunder,  such nominee shall follow the direction of
Pledgee,  if given, and Pledgor agrees that such nominee shall not be liable for
any action or omission taken  hereunder in good faith  pursuant to  instructions
from Pledgee.

         8.   Release of Pledged TradeArk Interest.  The  Pledgee  shall release
the Pledged  TradeArk  Interest to the Pledgor when the Modified Note shall have
been paid in full;  provided,  however,  that if at such time there shall be due
from Pledgor under this Pledge  additional  charges which theretofore arose as a
result of the default under any of the aforesaid  instruments then Pledgee shall
not release the Pledged  TradeArk  Interest to the Pledgor until such additional
charges  shall  have been paid in full;  and the  Pledgee  shall  deliver to the
Pledgor the  TradeArk  Interest  pledged  under this  Pledge and  Pledgee  shall
execute and deliver, or cause to be executed and delivered,  to the Pledgor such
instruments  as may be necessary  to cancel this Pledge,  and revest the Pledged
TradeArk   Interest  in  the  Pledgor   free  and  clear  of  the  lien  hereof.
Notwithstanding,  Pledgor  may  substitute  other  collateral  for  the  pledged
TradeArk Interest, pursuant to Section 2 of the Security Agreement.

         9.   Notices.  All  communications   provided  for  hereunder shall  be
addressed to Capitol Communities  Corporation 900 N. Federal Highway, Suite 410,
Boca Raton,  Florida 33432, if to Capitol  Development of Arkansas,  Inc., 10605

         10.  Applicable  Law. This Agreement shall be construed and enforced in
accordance with the laws of the State of Florida.

         11.  Successors and Assigns, etc.  All of the covenants and  provisions
in this Pledge by, or for the benefit of, the Pledgee and the Pledgor shall bind
and inure to the  benefit  of their  respective  successors,  heirs,  executors,
administrators and assigns.

         12.  Additional Security. This Pledge is without prejudice to the right
of Pledgee to enforce collection of the Modified Note due and payable,  by suit,
or in any lawful manner,  or resort to any other security for the payment of the
said Note, this Pledge being additional, cumulative, and concurrent security for
the payment of the said Note. The enumeration of certain rights,  privileges and
options in this Pledge as vested in Pledgee and its successors  and assigns,  is
not and shall not be  construed  as a waiver  of, nor to impair in any way other
rights of Pledgee and its  successors  or  assigns,  either at law or in equity,
independent  of this  instrument,  concerning  this, or any of the  liabilities,
obligations, indebtedness, or collateral security involved in the said Note.
