                                 OPERATING NOTE
                                (Cimarron Casino)

                                                           Minnetonka, Minnesota
                                                                January 27, 2005

     FOR VALUE RECEIVED, IOWA TRIBE OF OKLAHOMA ("MAKER"), A FEDERALLY-CHARTERED
CORPORATION, CREATED PURSUANT TO SECTION 3 OF THE OKLAHOMA INDIAN WELFARE ACT
OF JUNE 26, 1936 (49 STAT. 1967), UNDER A FEDERAL CHARTER ISSUED TO THE IOWA
TRIBE OF OKLAHOMA ("IOWA TRIBE"), A FEDERALLY RECOGNIZED INDIAN TRIBE, promises
to pay to the order of LAKES IOWA MANAGEMENT, LLC, A MINNESOTA LIMITED LIABILITY
COMPANY ("LENDER"), in the United States of America, in immediately available
funds, at such place as the holder hereof may from time to time designate, or in
the absence of such designation, at the office of the Lender, 130 Cheshire Lane,
Minnetonka, Minnesota 55305, the principal sum of the aggregate unpaid principal
amount of all "Guaranteed Minimum Payment Advances" and "Working Capital
Advances" made to Maker pursuant to Sections 5.3(b) and 5.7, respectively, of
the Management Agreement for a Gaming Facility and Related Ancillary Facilities
for the Cimarron Casino dated January 27, 2005 entered into between the parties
(the "Management Contract"), plus interest on any Working Capital Advances from
the date of such advances, in like money, in accordance with the following terms
and provisions:

     1. Defined Terms. Capitalized terms used herein and not defined shall have
the meanings given them in the Management Contract.

     2. Interest. No interest shall accrue on any Minimum Guaranteed Payment
Advances. Each Working Capital Advance as and when made pursuant to the terms of
the Amended Memorandum Agreement shall bear interest at the Interest Rate, as
described herein, from and including the date the proceeds of such Working
Capital Advance are advanced (such date the "Funding Date" of such Advance)
through the date of payment.

     3. Repayment; Limited Recourse Obligations. The obligation of Maker to
repay the funds advanced shall be a Limited Recourse obligation, as defined in
the Management Contract, and secured by the real and personal property described
therein. Principal and interest, as applicable, on each Minimum Guaranteed
Payment Advance and Working Capital Advance (each an "Advance") shall be repaid
in accordance with the terms and provisions set forth in the Management
Contract. The Maker shall have the right to prepay all or any part of this
Operating Note at any time without penalty or premium provided any partial
payment is at least $10,000 or an even multiple thereof, but any such prepayment
shall be applied to the installments of principal due hereunder in the inverse
order of maturity. In the event that the term of the Management Contract is
tolled under Section 6.6 thereof, Maker's obligation to make the monthly
installment payment hereunder shall be likewise tolled until the tolling under
Section 6.6 ceases (except to the extent that the Project shall receive any
business interruption insurance proceeds in connection with tolling under
Section 6.6, in which case Maker's obligation to make monthly installment
payments shall not be tolled).

     4. Interest Rate. The Interest Rate means an interest rate equal to the
greater of the


                                       -1-

<PAGE>

prime rate of Chase Manhattan Bank, N.A. (or any successor Bank by acquisition
or merger) plus two percent (2%) per annum or the same rate as the financing
provided by any third party lender for the development, construction and
equipping of the Project Facilities in place at the time of the advance, fixed
as of the first business day of each calendar month. Interest at the foregoing
rate shall accrue and shall be payable as a Limited Recourse obligation as
provided in the Management Contract. Interest shall be computed for the actual
number of days elapsed on the basis of a year consisting of 360 days. It is
intended that the rate of interest hereon shall never exceed the maximum rate,
if any, which may be legally charged on the Loan evidenced by this Operating
Note ("Maximum Rate"), and if the provisions for interest contained in this
Operating Note would result in a rate higher than the Maximum Rate, interest
shall nevertheless be limited to the Maximum Rate and any amounts which may be
paid toward interest in excess of the Maximum Rate shall be applied to the
reduction of principal, or, at the lawfully exercised option of the Lender,
returned to Maker.

     5. Record of Amounts Owed. Maker hereby authorizes Lender to record on its
books all Advances made to the Maker and all payments of principal amounts and
interest in respect of such Advances, which shall be presumptive evidence as to
the outstanding principal amount of all Advances; provided, however, that the
failure to make such notation with respect to any Advance or payments shall not
limit or otherwise affect the obligations of Maker.

     6. Default; Acceleration. If any Event of Default occurs, then the
outstanding principal amount of this Operating Note, any interest accrued
thereon from time to time, and any other sums then remaining unpaid hereunder,
at the option of the holder hereof and without notice, shall become immediately
due and payable and Lender may exercise any other rights or remedies available
under any Transaction Documents or applicable law. Failure to exercise any such
option shall not constitute a waiver of the right to exercise the same at a
later time or in the event of any subsequent default. The following shall
constitute "Events of Default" for purposes of this Operating Note:

     (a)  Failure by Maker to make timely payments of any of the installments of
          principal, interest or other amounts hereunder, which is not cured
          within ten (10) days after written notice of such nonpayment is
          delivered to Maker; or

     (b)  The occurrence of any event of default under any credit facility, term
          loan or any other agreement entered into by Maker for the use of
          borrowed funds, with respect to which the creditor has recourse to
          assets of the Project, and with respect to which (i) the creditor has
          accelerated the maturity of the indebtedness of Maker to such
          creditor, or (ii) the creditor has initiated action to collect such
          indebtedness; or

     (c)  A material default by Maker in the performance by Maker of any of its
          covenants or commitments under the Management Contract or any
          Transaction Document or under any other agreement entered into with or
          in favor of Lender or any Affiliate of Lender, or a material default
          by Maker's Affiliate under any agreement executed by an Affiliate of
          Maker in favor of Lender or any Affiliate of Lender which default is
          not cured by Maker or its Affiliate as applicable within the
          applicable cure period thereunder after written notice of default is
          delivered to Maker or its Affiliate; provided, however, that if the
          nature of such default (but specifically excluding


                                       -2-

<PAGE>

          defaults curable by the payment of money) is such that it is not
          possible to cure such default within the cure period, such period
          shall be extended for so long as the breaching party shall be using
          diligent efforts to effect a cure thereof but no more than an
          additional sixty (60) days; or

     (d)  The Management Contract shall be terminated by either the Maker or the
          Lender; or

     (e)  Any representation or warranty given to the Lender by the Maker (or
          any of its representatives) in connection with entering into the
          Management Contract or the other Transaction Documents and/or any
          borrowing thereunder, or given by an Affiliate of Maker in connection
          with any agreement executed by an Affiliate of Maker in favor of
          Lender or any Affiliate of Lender, or required to be furnished under
          the terms thereof, shall prove untrue or misleading in any material
          respect (as determined by the Lender in the exercise of its reasonable
          judgment) as of the time when given or shall fail to be true and
          correct in all material respects at any time during the term of the
          agreement; or

     (f)  There shall have been filed or commenced against Maker an involuntary
          case under any applicable bankruptcy, insolvency or other similar law
          now or hereafter in effect or an action shall have been commenced to
          appoint a receiver, liquidator, assignee, custodian, trustee,
          sequestrator (or similar official) of Maker or for any substantial
          part of Maker's property or for the winding up or liquidation of
          Maker's affairs and such action or proceeding shall not have been
          dismissed within sixty (60) days; or

     (g)  Maker shall commence a voluntary case under any applicable bankruptcy,
          insolvency or other similar law now or hereafter in effect; or shall
          consent to the entry of an order for relief in an involuntary case
          under any such law; or shall consent to the appointment of or taking
          possession by a receiver, liquidator, assignee, trustee, custodian,
          sequestrator (or other similar official) of Maker or of any
          substantial part of the Maker's property; or shall make any general
          assignment for the benefit of creditors; or shall take any action in
          furtherance of any of the foregoing or shall be insolvent.

     7. Security. This Operating Note shall be secured by a security interest in
the Collateral granted by Maker to Lender pursuant to the Management Contract
and the other Transaction Documents, including the Dominion Account Agreement.

the fullest extent permitted by law presentment, demand, protest, notice of
protest, notice of dishonor and notice of any other kind (except as specifically

     9. Remedies Cumulative. The remedies of the Lender, as provided in this

concurrent and may be pursued singularly, successively or together, at the sole

right or remedy shall in no event be construed as a waiver or release thereof.

AND COVENANT THAT NO COLLATERAL SECURITY WITH RESPECT TO THIS OPERATING NOTE IS
USED OR IS INTENDED TO BE USED BY MAKER AS A DWELLING OR AS A HOME AND THAT THE
