that, to the extent notice of sale shall be required by law, at least ten (10)

shall not be obligated to make any sale of Collateral regardless of notice of
sale having been given. Secured Party may, without notice or publication,
adjourn any public or private sale, or cause the same to be adjourned from time
to time by announcement at the time and place fixed for sale or, with respect to
a private sale, after which such sale may take place, and any such sale may,
without further notice, be made at the time and place to which it was so
adjourned or, with respect to a private sale, after which such sale may take
place. Each purchaser at any such sale shall hold the property sold free from
any claim or right on the part of Debtor or the Iowa Tribe, and the Debtor and
the Iowa Tribe hereby waives, to the full extent permitted by law, all rights of
stay and/or appraisal which Debtor or the Iowa Tribe now has or may at any time
in the future have under any rule of law or statute now existing or hereafter
enacted. The Debtor or the Iowa Tribe also hereby waive any claims against
Secured Party arising by reason of the fact that the price at which any
Collateral may have been sold at a private sale was less than the price which
might have been obtained at a public sale, even if Secured Party accepts the
first offer received and does not offer such Collateral to more than one
offeree. The parties hereto agree that the notice provisions, method, manner and
terms of any sale, transfer or disposition of any Collateral in compliance with
the terms set forth herein or any other provision of this Security Agreement are
commercially reasonable;

          (c) exercise any or all of the rights and remedies provided for by the
Oklahoma Uniform Commercial Code, applicable law or by other agreement,
specifically including, without limitation, the right to recover the attorneys'
fees and other expenses incurred by Secured Party in the enforcement of this
Security Agreement or in connection with the Debtor's redemption of the
Collateral; provided however that if the Debtor or the Iowa Tribe is the
prevailing party in any action or proceeding seeking enforcement of this
Agreement, then the Debtor or the Iowa Tribe shall not be and Secured Party
shall be responsible for such related costs and expenses. Secured Party may
exercise its rights under this Security Agreement independently of any other
collateral or guaranty that Debtor or the Iowa Tribe may have granted or
provided to Secured Party in order to secure payment and performance of the
Secured Obligations, and Secured Party shall be under no obligation or duty to
foreclose or levy upon any other collateral given by Debtor or the Iowa Tribe to
secure any Secured Obligation or to proceed against any guarantor before
enforcing its rights under this Security Agreement. The Debtor or the Iowa Tribe
shall reimburse Secured Party upon demand for, or Secured Party may apply any
proceeds of Collateral to, the reasonable costs and expenses (including
attorneys' fees, transfer taxes and any other charges) incurred by Secured Party
in connection with any sale, disposition, repair, replacement, alteration,
addition, improvement or retention of any Collateral hereunder; provided however
that if the Debtor or the Iowa Tribe is the prevailing party in any action or
proceeding seeking enforcement of this Agreement, then the Debtor or the Iowa
Tribe shall not be and Secured Party shall be responsible for such related costs
and expenses;

          (d) the powers conferred on the Secured Party by this Section 6.2 and
otherwise in this Agreement are solely to protect the Secured Party's interests
in the Collateral and shall not impose any duty upon it to exercise any such
powers. The Secured Party shall be accountable only for amounts that it actually
receives as a result of the exercise of such powers, and neither the Secured
Party nor any of their officers, directors, trustees, employees, representatives
or


                                 Page 10 of 15

<PAGE>

agents shall, in the absence of willful misconduct or gross negligence, be
responsible to the Debtor for any act or failure to act pursuant to this Section
6.2 or otherwise pursuant to this Agreement; and

          (e) the Secured Party's sole duty with respect to the custody,
safekeeping and preservation of the Collateral, under Section 9-207 of the Code
or otherwise, shall be to deal with it in the same manner as the Secured Party
deals with similar property for their own account. Neither the Secured Party nor
any of their directors, officers, trustees, employees, representatives, or
agents shall be liable for failure to demand, collect or realize upon all or any
part of the Collateral or for any delay in doing so or shall be under any
obligation to sell or otherwise dispose of any Collateral upon the request of
the Debtor or otherwise.

Such notices, requests and other communications sent as provided hereinabove
shall be effective when received by the addressee thereof, unless sent by
registered or certified mail, postage prepaid, in which case they shall be
effective exactly three (3) business days after being deposited in the United
States mail. The parties hereto may change their addresses by giving notice
thereof to the other parties hereto in conformity with this section.

          (b) Headings. The various headings in this Security Agreement are
inserted for convenience only and shall not affect the meaning or interpretation
of this Security Agreement or any provision hereof.

          (c) Amendments. This Security Agreement or any provision hereof may be
changed, waived, or terminated only by a statement in writing signed by the
party against which such change, waiver or termination is sought to be enforced,
and then any such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

          (d) No Waiver. No failure on the part of Secured Party to exercise,
and no delay in exercising, and no course of dealing with respect to, any power,
privilege or right under this Security Agreement or any related agreement shall
operate as a waiver thereof nor shall any single or partial exercise by Secured
Party of any power, privilege or right under this Security Agreement or any
related agreement preclude any other or further exercise thereof or the exercise
of any other power, privilege or right. The powers, privileges and rights in
this Security Agreement are cumulative and are not exclusive of any other
remedies provided by law. No waiver by Secured Party of any default hereunder
shall be effective unless in writing, nor shall any waiver operate as a waiver
of any other default or of the same default on a future occasion.

          (e) Binding Agreement. All rights of Secured Party hereunder shall
inure to the benefit of its successors and assigns. Subject to the terms of the
Management Contract, neither Debtor nor the Iowa Tribe shall assign any of its
interest under this Security Agreement without the prior written consent of
Secured Party. Any purported assignment inconsistent with this provision shall,
at the option of Secured Party, be null and void.

          (f) Entire Agreement. This Security Agreement, together with any other


                                 Page 12 of 15

<PAGE>

agreement executed in connection herewith, is intended by the parties as a final
expression of their agreement and is intended as a complete and exclusive
statement of the terms and conditions thereof. Acceptance of or acquiescence in
a course of performance rendered under this Security Agreement shall not be
relevant to determine the meaning of this Security Agreement even though the
accepting or acquiescing party had knowledge of the nature of the performance
and opportunity for objection.

          (g) Severability. If any provision or obligation of this Security
Agreement should be found to be invalid, illegal, or unenforceable in any
jurisdiction, the validity, legality and enforceability of the remaining
provisions and obligations or any other agreement executed in connection
herewith, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby and shall nonetheless remain in
full force and effect to the maximum extent permitted by law.

          (h) Survival of Provisions. All representations, warranties and
covenants of Debtor and the Iowa Tribe contained herein shall survive the
execution and delivery of this Security Agreement, and shall terminate only upon
the termination of this Security Agreement pursuant to Subsection 7(k) hereof.

          (i) Power of Attorney. The Debtor and the Iowa Tribe hereby
irrevocably appoint Secured Party its attorney-in-fact, which appointment is
coupled with an interest, with full authority in the place and stead of Debtor
and the Iowa Tribe and in the name of each, Secured Party or otherwise, from
time to time in Secured Party's discretion (a) to execute and file financing and
continuation statements (and amendments thereto and modifications thereof) on
behalf and in the name of the Debtor and the Iowa Tribe with respect to the
security interests granted or purported to be granted hereby, (b) to take any
action and to execute any instrument which Secured Party may deem necessary or
advisable to exercise its rights under Section 5(p) hereunder, and (c) upon the
occurrence and during the continuance of an Event of Default, to take any action
and to execute any instrument which Secured Party may deem necessary or
advisable to accomplish the purposes of this Security Agreement, including,
without limitation:

               (i) to obtain and adjust insurance required to be paid to Secured
Party pursuant hereto;

               (ii) to ask, demand, collect, sue for, recover, compound, receive
and give acquittance and receipts for moneys due and to become due under or in
respect of any of the Collateral;

               (iii) to receive, endorse and collect any drafts or other
instruments, documents and chattel paper, in connection with clauses (i) and
(ii) above;

               (iv) to sell, convey or otherwise transfer any item of Collateral
to any purchaser thereof; and

               (v) to file any claims or take any action or institute any
proceedings which Secured Party may deem necessary or desirable for the
collection of any of the Collateral or otherwise to enforce the rights of
Secured Party with respect to any of the Collateral.

          (j) Counterparts. This Security Agreement and any amendments, waivers,
consents or supplements may be executed in any number of counterparts and by
facsimile, each of which when so executed and delivered shall be deemed an
original, but all of which shall together constitute one and the same agreement.

          (k) Termination of Agreement. Unless earlier terminated pursuant to
Section 3 hereof, this Security Agreement and the security interest hereunder
shall not terminate until full and final payment and performance of all
indebtedness and obligations secured hereunder. At such time, Secured Party
shall reassign and redeliver to Debtor or the Iowa Tribe all of the Collateral
hereunder which has not been sold, disposed of, retained or applied by Secured
Party in accordance with the terms hereof, and execute and deliver to Debtor or
the Iowa Tribe such documents as Debtor may reasonably request to evidence such
termination. Such reassignment and redelivery shall be without warranty by or
recourse to Secured Party, and shall be at the expense of Debtor or the Iowa
Tribe; provided, however, that this Security Agreement (including all
representations, warranties and covenants contained herein) shall continue to be
effective or be reinstated, as the case may be, if at any time any amount
received by Secured Party in respect of the indebtedness and obligations secured
hereunder is rescinded or must otherwise be restored or returned by Secured
Party upon or in connection with the insolvency, bankruptcy, dissolution,
liquidation or reorganization of Debtor or the Iowa Tribe or any other person or
upon or in connection with the appointment of any intervenor or conservator of,
or trustee or similar official for, Debtor, or the Iowa Tribe or any other
person or any substantial part of its assets, or otherwise, all as though such
payments had not been made.

          (l) Sovereign Immunity Waiver; Arbitration; Submission to
Jurisdiction. This Agreement constitutes the Security Agreement as defined and
referred to in the Management Contract. As such and without limiting the scope
of such agreements, the provisions of Section 9.10 and Article 10 of the
Management Contract apply to this Agreement and are hereby incorporated by
reference, including, without limitation, the limited sovereign immunity waiver,
limitations on recourse and arbitration provisions contained therein and the
Resolution of Limited Waiver attached thereto. This Agreement will be governed
by the internal laws of the State of Oklahoma without giving effect to its
conflict of laws principles. The parties hereto may not change the law governing
this Agreement without express written consent of the Debtor and Secured Party.
