             AMENDED AND RESTATED GAMING MACHINE LOCATION AGREEMENT
 
     THIS AMENDED AND RESTATED GAMING MACHINE LOCATION AGREEMENT (the
"Agreement") is entered into as of this 1st day of December, 1995 (the
"Effective Date"), between AMERICAN HERITAGE AMUSEMENT CORPORATION, a California
corporation ("Lessor"), and INLAND CASINO CORPORATION, a Utah corporation, or
its successor ("Lessee").
 
                                    RECITALS
 
     WHEREAS, Lessor is in the business of leasing video machines and games; and
 
     WHEREAS, Lessor and Lessee entered into that certain Gaming Machine
Location Agreement dated as of July 15, 1993, and now desire to amend, restate,
and supersede such agreement as set forth below.
 
                                   AGREEMENT
 
     NOW THEREFORE, in consideration of the premises and of the mutual covenants
and agreements contained herein, the parties hereto do hereby represent,
warrant, covenant, and agree as follows:
 
     1. Lessor will lease to Lessee on a non-exclusive basis machines comprised
of, among other types, video pull-tab games, video poker, video keno, and video
bingo. The total number of Machines and the types of Machines to be leased shall
be in the sole discretion of Lessee.
 
     2. The parties agree that Lessee shall pay Lessor rent for the lease of the
Machines at the rate of Two Hundred Dollars ($200.00) per month per fully
operational Machine. If, for any reason, a Machine is inoperable, the lease
payment for such Machine shall be pro rated based on the total number of days in
a given month that such Machine was fully operational. Each monthly lease
payment shall be paid in arrears, shall be due on the first (1st) day of the
following month, but shall not be deemed late unless the Lessor has not received
the payment by the tenth (10th) day of the month or, if the 10th day is a
Saturday, Sunday, or a holiday, by the first business day following the 10th day
of the month. Lessor acknowledges and agrees that Lessor shall not have any
interest in the proceeds of the Machines. A Machine shall be deemed to be
"inoperable" if the Machine is not operating properly and Lessee, through no
fault of its own, is unable to repair the Machine within a period of twenty-four
(24) hours.
 
     3. Lessee at its sole expense shall be responsible for maintaining and
repairing the Machines and for providing all supplies and accessories necessary
to operate the Machines. Nothing in this paragraph shall be construed to prevent
Lessee from returning to Lessor any inoperable Machine. In the event of such a
return, Lessor shall promptly provide Lessee with a replacement Machine of
Lessee's choice.
 
     4. The parties acknowledge and agree that if the Barona Band of Mission
Indians requests Lessee to remove certain machines in order to meet the
requirements of any compact between the Barona Band of Mission Indians and the
State of California, in order to induce the State of California to enter into
such a compact, or for any other reason determined sufficient by the Barona Band
of Mission Indians, Lessor will immediately remove some or all such machines as
specified by the Barona Band of Mission Indians. Lessee shall not suffer any
penalty, loss, or detriment of any kind, including, without limitation, any
further obligation to pay rent to Lessor, by or as a result of any such action.
 
     5. To the extent that this Agreement constitutes a "collateral agreement"
within the meaning of the Indian Gaming Regulatory Act, its regulations, and/or
any successor statute or regulation, Lessor shall, at its sole expense, take any
and all action necessary to obtain any and all approvals required by or from the
National Indian Gaming Commission for Lessor and/or this Agreement. If Lessor
does not obtain such approvals within thirty (30) days of the Effective Date of
this Agreement or such other time period as may be specified by the National
Indian Gaming Commission or any other agency or commission with authority to do
so, whichever is later, Lessee may, in its sole discretion, terminate this
Agreement without further obligation or liability whatsoever to Lessor.
 
                                        1

     6. The premises upon which the Machines will be located is known as the
Barona Casino on the reservation of the Barona Band of Mission Indians located
at 1000 Wildcat Canyon Road, Lakeside, California, 92040.
 
     7. It is agreed between the parties that, except as otherwise provided for
in this Agreement, Lessor shall retain title to all of the Machines placed at
the above location and shall have the right to inspect the Machines during
normal business hours and upon reasonable prior notice to Lessee.
 
     8. The term of this Agreement shall be for two (2) years commencing as of
the Effective Date; provided, however, that Lessee may terminate this Agreement,
with or without cause, by giving Lessor thirty (30) days prior written notice.
Immediately following the expiration of the 30-day period, this Agreement shall
terminate.
 
     9. In the event that Lessee, the Barona Band of Mission Indians, the United
States Attorney for the Southern District of California, any governmental
official or agency with authority to do so, or any court of competent
jurisdiction determines that Lessee may not use the Machines described in this
Agreement until there is a compact in effect between the Barona Band of Mission
Indians and the State of California covering either the initial Machines
supplied by Lessor or replacements thereto as described above, Lessee shall give
Lessor written notice of such determination. In the event of such notice, Lessee
may elect to immediately terminate this Agreement and to remove all of the
Machines from the premises. Neither the determination that Lessee may not use
the Machines described in this Agreement until there is such a compact in effect
nor the termination of this Agreement under this paragraph shall result in any
liability of Lessee to Lessor, including, without limitation, any liability to
pay further rent.
 
     10. Lessor represents and warrants as follows:
 
          a. Lessor has the corporate power and authority and all licenses,
     certificates and permits required by governmental authority to enter into
     this Agreement.
 
          b. Lessor owns all right, title, and interest in and to the Machines,
     their component parts, and patents covering the Machines, both issued and
     pending, including, without limitation, the computer software necessary to
     operate games on the Machines and that Lessor's ownership is free and clear
     of any and all liens, encumbrances, and interests of any other person or
     entity.
 
          c. No other person or entity, without limitation, has any right,
     title, interest, or claim in or to Lessor, this Agreement, the Machines,
     any component parts of the Machines, patents covering the Machines, both
     issued and pending, as well as any other form of intellectual property.
 
          d. The execution, delivery and performance of this Agreement, and the
     execution of any other document related hereto, will not conflict with, or
     constitute a default or a condition which with the giving of notice or the
     passing of time or both would constitute a default under any term or
     provision of any contract, instrument, mortgage, loan, law, trust,
     judgment, regulation or other restriction to which Lessor is a party or
     which is applicable to Lessor.
 
          e. There is no litigation pending or threatened against Lessor that
     would materially affect Lessor's ability to perform each and every of its
     obligations under this Agreement or any instrument or agreement related
     hereto.
 
          f. Neither Lessor, nor any of its agents, employees, or
     representatives, have engaged in any conduct that may result in civil or
     criminal liability with regard to this Agreement or the provision of the
     Machines to Lessee for the purposes contemplated hereunder.
 
          g. The representations and warranties contained herein shall be deemed
     to be continuing covenants of Lessor and shall continue beyond the term of
     this Agreement or any extension or termination of this Agreement.
 
     11. Lessor agrees to indemnify and to hold Lessee, the Barona Band of
Mission Indians, and their respective agents, directors, officers, employees,
attorneys, successors, and assigns harmless from and against any and all claims,
losses, liabilities, and expenses, including, without limitation, attorney's
fees and the costs
 
                                        2
<PAGE>   3
 
and expenses of litigation, arising from or in connection with, directly or
indirectly, any of Lessor's representations and warranties.
 
     12. All of Lessor's obligations under this Agreement shall be personally
guaranteed by Fred Gillmann ("Guarantor") who shall execute a personal guarantee
in favor of Lessee in substantially the same form as the personal guarantee
attached hereto as Exhibit "A". Guarantor shall execute the personal guarantee
concurrently with Lessor's execution of this Agreement. Lessee's obligations
under this Agreement shall be conditioned upon receipt of Guarantor's executed
personal guarantee.
 
     13. Lessor for itself, its successors, and assigns, fully releases and
discharges Lessee, Barona Band of Mission Indians, and their respective
officers, directors, employees, shareholders, attorneys, accountants, other
professionals, insurers and agents of the other (collectively "Agents"), and all
related entities, including but not limited to heirs, executors, administrators,
personal representatives, assigns, parent subsidiary and sister corporations,
affiliates, partners and co-venturers (collectively the "Released Parties"),
from all rights, claims, demands, actions or causes of action which Lessor now
has or may have against the Released Parties from any source whatsoever, whether
or not arising from or related to that certain Gaming Machine Location Agreement
dated as of July 15, 1993, except those rights and obligations arising out of
this Agreement. Lessor expressly waives all rights under Section 1542 of the
Civil Code of the State of California, which Lessor understands provides as
follows:
 
        A general release does not extend to claims which the creditor does not
        know or suspect to exist in his favor at the time of executing the
        release, which if known by him must have materially affected his
        settlement with the debtor.
 
     14. General Provisions.
 
          a. Incorporation By Reference.  The recitals contained herein are
     incorporated herein by reference as if set forth in full herein.
 
          b. Effective Date.  The "Effective Date" of this Agreement shall be
     the date first set forth above.
 
          c. Removal of Machines.  Except as provided for in paragraph 4, in the
     event of any termination of this Agreement by and upon the written request
     of Lessee, Lessor shall remove all of the Machines from the premises not
     later than thirty (30) days after such notice of termination. If Lessor
     fails or refuses to remove the Machines within such 30-day period, Lessee
     may, in its sole discretion and at Lessor's sole expenses, remove and store
     the Machines. Following any termination of this Agreement and until such
     time as all of the Machines are removed from the premises, Lessee may
     continue to use the Machines as provided herein, and Lessee and Lessor
     shall remain subject to all of the terms and conditions of this Agreement
     for so long as any of the Machines remain on the premises.
 
          d. Notices.  All notices, requests, demands, directions, and other
     communications provided for hereunder (a "Notice") must be in writing and
     must be sent via certified mail (return receipt requested), personally
     delivered, or sent by overnight courier to the appropriate party at its or
     his respective address set forth below or, as to any party, at any other

          e. Headings.  The captions and paragraph headings used in this
     Agreement are inserted for convenience of reference only and are not
     intended to define, limit or affect the interpretation or construction of
     any term or provision hereof.
 
          f. Entire Agreement.  This Agreement, together with all exhibits
     attached hereto and other agreements expressly referred to herein,
     constitutes the entire agreement between the parties with respect to the
     subject matter of this Agreement. All prior or contemporaneous agreements,
     understandings, representations, warranties and statements, oral or
     written, relating to the subject matter hereof are superseded.
 
          g. Modification: No Waiver.  No modification, amendment or discharge
     of this Agreement shall be valid unless the same is in writing and signed
     by both Lessor and Lessee. No failure of Lessee to enforce its rights,
     remedies, or options hereunder shall be deemed to be a waiver of any of its
     rights, remedies or options hereunder or at law, and Lessee may at any time
     that a default or breach exists or continues to exist, enforce any or all
     of its rights, remedies and options arising by reason of such or any other
     default.
 
          h. Severability.  If any term, provision, covenant or condition of
     this Agreement is held to be invalid, void or otherwise unenforceable, to
     any extent, by any court of competent jurisdiction, the remainder of this
     Agreement shall not be affected thereby, and each term, provision, covenant
     or condition of this Agreement shall be valid and enforceable to the
     fullest extent permitted by law.
 
          i. Arm's Length Agreement.  This Agreement has been negotiated at
     arm's length and between persons sophisticated and knowledgeable in the
     matters dealt with in this Agreement. In addition, each party has been
     represented by experienced and knowledgeable legal counsel. Accordingly,
     any rule of law (including, without limitation, California Civil Code
     section 1654) or legal decision that would require interpretation of any
     ambiguities in this Agreement against the party that has drafted it is not
     applicable and is waived. The provisions of this Agreement shall be
     interpreted in a reasonable manner to effect the purpose of the parties and
     this Agreement.

          j. Governing Law.  This Agreement shall be governed, construed and
     enforced in accordance with applicable federal law and, to the extent there
     is no applicable federal law, then in accordance with the laws of the State
     of California as applicable to contracts made wholly between residents of
     California, regardless of the laws that otherwise may be applicable under
     principles of conflicts of law.
 
          k. Successors and Assignment.  Lessor may not assign this Agreement or
     any of its rights or obligations hereunder without the prior written
     consent of Lessee, which consent shall not be unreasonably withheld. Any
     such assignment in violation of this provision shall be null and void.
     Subject to the foregoing, all terms of this Agreement shall be binding
     upon, inure to the benefit of, and be enforceable by the parties hereto and
     their respective heirs, legal representatives, successors and permitted
     assigns. The parties hereto acknowledge and agree that this Agreement and
     all related agreements attached to this Agreement as exhibits are not,
     either individually or collectively, executory contracts and cannot be
     either assumed or assigned, or both, pursuant to section 365(e)(2) of the
     United States Bankruptcy Code, 11 U.S.C. Section 365(e)(2).
 
          l. Further Assurances.  The parties agree to take such further action
     and execute such documents and instruments as may reasonably be required in
     order to more effectively carry out the terms of this Agreement and the
     intentions of the parties.
 
          m. Attorneys' Fees.  In the event any action is brought for
     enforcement or interpretation of this Agreement, the prevailing party shall
     be entitled to recover reasonable attorneys' fees and costs incurred in
     said action, including enforcement and collection of any judgement or award
     rendered therein. Said costs and attorneys' fees shall be included as part
     of the judgment in any such action.
 
          n. Counterparts.  This Agreement may be executed in one or more
     identical counterparts, all of which shall together constitute one and the
     same instrument when each party has signed one counterpart.
 
          o. Time of the Essence.  Time is of the essence under this Agreement
     and any amendment, modification or revision of it.
 
     IN WITNESS WHEREOF, the parties have entered into this Amended and Restated
Gaming Machine Location Agreement as of the date first written above.
