                                   PAWNEE NOTE

                                                                  Minnetonka, MN
                                                                January 12, 2005

     FOR VALUE RECEIVED, PAWNEE TRADING POST GAMING CORPORATION ("MAKER"), A
WHOLLY-OWNED SUBSIDIARY OF THE PAWNEE TRIBAL DEVELOPMENT CORPORATION, EACH
CREATED UNDER THE CONSTITUTION OF AND A GOVERNMENTAL SUBDIVISION OF THE PAWNEE
NATION OF OKLAHOMA, A FEDERALLY RECOGNIZED INDIAN TRIBE, promises to pay to the
order of LAKES PAWNEE CONSULTING, 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 aggregate unpaid principal amount of all
advances made to Maker pursuant to the "Project Preliminary Development Loan" as
set forth in Article 3 of the Gaming Development Consulting Agreement dated
January 12, 2005 between the parties (the "Gaming Development Consulting
Agreement"), plus interest thereon 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 Gaming Development Consulting Agreement.

     2. Advances. Pursuant to the Gaming Development Consulting Agreement,
Lender has agreed to extend the Project Preliminary Development Loan to Maker,
such funds to be loaned in more than one advances (each, an "Advance") as
entered on the Schedule of Advances attached hereto as Schedule A. Each Advance
shall bear interest at the Interest Rate, as described herein, from and
including the date the proceeds of such 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 limited to the Collateral as described in the
Gaming Development Consulting Agreement. Commencing on the twenty-fifth (25th)
day after the Opening Date for the Project, in the event the Project Preliminary
Development Loan has not previously been repaid through the Project Permanent
Financing, principal and interest on this Note shall be paid in twenty-four
equal monthly installments. Maker shall have the right to prepay all or any part
of this Pawnee 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.

     4. Interest Rate. The Interest Rate means, as to each Advance, an interest
rate equal to the greater of the prime rate of Chase Manhattan Bank, N.A. (or
any successor Bank) plus two percent (2%), per annum or the same rate as the
Project Permanent Financing in place at the time of the advance, fixed as of the
first business day of each calendar month. Interest at the foregoing rate


                                      -1-

<PAGE>

shall accrue and be compounded annually and shall be payable solely from the
Collateral as provided in Gaming Development Consulting Agreement. 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
Project Preliminary Development Loan evidenced by Pawnee Note ("Maximum Rate"),
and if the provisions for interest contained in this Pawnee 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 and on Schedule A attached hereto all Advances made to the Maker and all
payments of principal amounts 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 in the payment of
any principal, interest or any other sums when due hereunder, or in the
performance of any covenant or agreement hereunder, and such default continues
beyond any applicable notice, grace and/or cure period, then the outstanding
principal amount of the Project Preliminary Development Loan, 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 the Gaming Development Consulting Agreement 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 Pawnee
Note:

     (a)  Failure by Maker to make timely payments of any of the installments of
          principal, interest or other amounts due 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)  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


                                      -2-

          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

     (e)  Any representation or warranty given to the Lender by Maker (or any of
          its representatives) in connection with entering into the Gaming
          Development Consulting Agreement 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
          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)  Default by Maker in the performance by Maker of any of its covenants

          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 after
          written notice of default is delivered to Maker or its Affiliate; or

     (g)  The Gaming Development Consulting Agreement shall be terminated by
          either the Maker or the Lender.
