disclose the results of the operations of the Company. Such books of account
shall be maintained on the method of accounting selected by the Managing Member
and on the basis of the Fiscal Year. Each Member, upon not less than seventy-two
(72) hours advance written notice to the Managing Member, at such Member's own
expense shall have the right to inspect, copy, and audit the Company's books and
records at any time during normal business hours without notice to any other
Member.

          b.  The Company shall keep at its registered office such records as
are required by the Act.

     7.2. Tax Returns. The Managing Member shall cause independent certified
          -----------
public accountants of the Company to prepare and timely file all income tax and
other tax returns of the Company. The Company shall furnish to each Member a
copy of all such returns together with all schedules thereto and such other
information which each Member may reasonably request in connection with such
Member's own tax affairs.

                                   ----------

     8.1. General Management.
          ------------------ 

          a.  The business and affairs of the Company shall be managed by or
under the direction of the Managing Member. The Managing Member shall direct,
manage and control the business of the Company and, subject to the limitations
and qualifications set forth in this Article 8, shall have full and complete
authority, power and discretion to make any and all decisions and to do any and
all things which the Managing Member shall deem to be reasonably required or
convenient in light of the Company's business and objectives.

     All actions on behalf of the Company may be taken only after Approval (as
hereinafter defined) by the Managing Member. During the period that Hilton and
Boomtown hold the Original Percentages of Voting Units, "Approval" and
"Approved" mean the unanimous approval of Hilton and Boomtown. During any period
that one or other of Hilton and Boomtown holds a higher percentage of Voting
Units than its Original Percentage, and the other's Voting Units have converted
to Non-Voting Units in accordance with Section 5.1 hereof, then the Person
holding the higher percentage than such Person's Original Percentage shall be
deemed the "Majority Member" and the other Person holding a lower percentage
than its Original Percentage shall be deemed the "Minority Member," "Approval"
and "Approved" shall mean approval by the Majority Member and Managing Member
shall be deemed to refer only to the Majority Member. By way of example, if
after the date hereof Boomtown holds 52% of the Voting Units and Hilton holds
48%, Approval and Approved shall mean approval solely by Boomtown, Boomtown
shall be the Majority

                                      -8-

 
Member, and therefore the Managing Member, and Hilton's Units shall be converted
to Non-Voting Units.

     Without limiting the generality of the foregoing, the Managing Member shall
have sole power and authority, on behalf of the Company, upon Approval:

          i.     to acquire property from any Person as the Managing Member may
determine. The fact that a Member is directly or indirectly an Affiliate of such
Person shall not prohibit the Managing Member from dealing with that Person;

          ii.    to establish policies for investment and to make investments of
Company funds (by way of example but not limitation) in time deposits, short
term governmental obligations, commercial paper or other investments;

          iii.   to make distribution of available cash to Members;

          iv.    to employ accountants, legal counsel, managers, managing agents
or other experts or consultants to perform services for the Company, including,
without limitation, those for the predevelopment and development of the Project
and to compensate them from Company funds;

          v.     to borrow money on behalf of the Company from banks, other
lending institutions, the Members, or Affiliates of the Members on such terms as
they deem appropriate, and in connection therewith, to hypothecate, encumber and
grant security interests in the assets of the Company to secure repayment of the
borrowed sums. Except as otherwise provided in the Act, no debt shall be
contracted or liability incurred by or on behalf of the Company except by the
Company's Managing Member;

          vi.    to purchase liability and other insurance to protect the
Company's Property and business;

          vii.   to organize Entities to serve as the Company's subsidiaries, to
determine the form and structure thereof and control the same;

          viii.  to execute, deliver and perform any agreements on behalf of the
Company, with any other Person for any purpose, subject to the spending limits
as Managing Member may Approve;

          ix.    to hire, terminate and compensate employees involved in the 
day-to-day operations of the Company's facilities; and

          x.     to determine maintenance, operation, fixtures, hours of
operation, service and promotional activities at the Company's Property.

     b.   Unless authorized to do so by this Agreement or by Approval of the
Managing Member, no Member, agent or employee of the Company shall have any
power or authority to bind the Company in any way, to pledge its credit or to
render it liable pecuniarily for any purpose. However, the Managing Member may
act (or may cause the Company to act) by a duly authorized power of attorney.

                                      -9-

 
             c.  At any time that the Managing Member consists of two Members,
the board of directors of each Subsidiary shall consist of any even number of
members and Boomtown and Hilton shall each be entitled to elect one-half of the
members of all such boards. In the event of a vacancy on the board of directors
of any Subsidiary, the Member who elected such director shall solely be entitled
to fill such vacancy. In all other circumstances, the board shall be appointed
by the sole Managing Member.

             d.  The Managing Member must at all times hold at least twenty
percent (20%) of all outstanding Member's Interests.

     8.2.    Actions Requiring Minority Member Approval.
             ------------------------------------------ 

     (a)     Notwithstanding any other provision of this Agreement, during any
time that the Managing Member consists solely of the Majority Member, and so
long as the Minority Member owns at least twenty percent (20%) of the total
Units, the Managing Member shall not take any of the following actions without
the consent of the Minority Member:

     (i)     Adoption of the annual budget for the Project;

     (ii)    The making of a capital expenditure in excess of $500,000.00;

     (iii)   The issuance of additional Units;

     (iv)    Transactions with an Affiliate other than transactions with
             Affiliates on terms consistent with an arms-length transaction with
             third-parties. After approval of the management agreement with an
             Affiliate as described in Section 8.5 by Hilton and Boomtown, any
             subsequent management agreement with an Affiliate upon
             substantially the same terms and conditions as the approved
             agreement shall not require the consent of the Minority Member; or

     (v)     Amendment of this Agreement or the Articles of Organization so as
             to adversely impact the Minority Member;

     (vi)    Expulsion of any Member pursuant to Section 10.6;

     (vii)   The requirement of additional Capital Contributions by the Members.

     (b)     In the event that Managing Member and the Minority Member are
unable to agree upon any proposed action which requires the consent of the
Minority Member pursuant to Section 8.2(a) above, either person may elect to
submit resolution of the issue to binding arbitration conducted in accordance
with the provisions of Section 8.09 hereof.

     8.3.    No Liability for Certain Acts. The Managing Member shall perform
             -----------------------------
its duties in good faith, in a manner such Managing Member reasonably believes
to be in the best interests of the Company, or not opposed to the best interests
of the Company. Provided the Managing Member so acts at all relevant times, the
Managing Member shall not be responsible to any Members because of a loss of
their investment in the Company or a loss in the operations of the Company. The
Managing Member does not, in any way, guarantee the return of the Members'
Capital Contributions or a profit for the Members from 

                                      -10-

 
the operations of the Company. The Managing Member shall incur no liability to
the Company or to any of the Members as a result of engaging in any other
business or venture. The Managing Member shall be entitled to rely on
information, opinions, reports or statements, including financial statements and
other financial data, in each case prepared or presented by Persons listed below
unless such Managing Member has knowledge concerning the matter in question that
would cause such reliance to be unwarranted:

     a.   one or more employees or other agents of the Company whom the Managing
Member reasonably believes to be reasonably reliable and competent in the
matters presented; and

     b.   legal counsel, public accountants, or other persons as to matters that
the Managing Member reasonably believes to be within such Persons' professional
or expert competence.

     8.4. Indemnity of the Managing Member, Employees or Agents.
          ----------------------------------------------------- 

          a.  The Company agrees to indemnify, pay, protect and hold harmless
such Managing Member (on demand of and to the satisfaction of such Managing
Member) from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, proceedings, costs, expenses and
disbursements of any kind or nature whatsoever (including, without limitation,
all reasonable costs and expenses in connection therewith, of investigation,
defense, appeal and -- provided that consent to settlement from all Members is
obtained, which consent shall not be unreasonably withheld -- expenses of
settlement, of any and all suits, actions or proceedings instituted against a
Managing Member or the Company) which may be imposed on, incurred by, or
asserted against a Managing Member or the Company in any way relating to or
arising out of, or alleged to relate to or arise out of, any action or inaction
on the part of the Company or on the part of a Managing Member, acting in good
faith and in a manner he reasonably believed to be in, or not opposed to, the
best interests of the Company, in connection with the formation, operation
and/or management of the Company, the Company's purchase and operation of the
Project, and/or as a result of a Managing Member's agreement to act as Managing
Member of the Company. If any action, suit or proceeding shall be pending or
threatened against the Company or a Managing Member relating to or arising out
of, or alleged to relate to or arise out of, any such action or nonaction, a
Managing Member shall have the right to employ, at the expense of the Company,
separate counsel of such Managing Member's choice in such action, suit or
proceeding and the Company shall advance the reasonable out-of-pocket expenses
of such Managing Member in connection therewith. The satisfaction of the
obligations of the Company under this Section shall be from and limited to the
assets of the Company and no Member shall have any personal liability on account
thereof. The foregoing rights of indemnification are in addition to and shall
not be a limitation of any rights of indemnification as provided in Sections
86.411 through 86.451 of the Act, as such may be amended from time to time.

          b.  This Section shall not limit the Company's power to pay or
reimburse expenses incurred by a Managing Member in connection with such
Managing Member's appearance as a witness in a proceeding at a time when the
Managing Member has not been made a named defendant or respondent in the
proceeding.

                                      -11-

 
          c.  The Company may indemnify and advance expenses to an employee or
agent of the Company who is not a Managing Member to the same or to a greater
extent as the Company may indemnify and advance expenses to a Managing Member;
and

          d.  The Company shall use its best efforts to purchase and maintain
insurance in the amount of at least $2,000,000.00, on behalf of a Person who is
or was a Managing Member, Member, employee, fiduciary, or agent of the Company
or who, while a Managing Member, Member, employee, fiduciary, or agent of the
Company, is or was serving at the request of the Company as manager, member,
director, officer, partner, trustee, employee, fiduciary, or agent of any other
foreign or domestic limited liability company or any corporation, partnership,
joint venture, trust, other enterprise, or employee benefit plan against any
liability asserted against or incurred by such Person in any such capacity or
arising out of such Person's status as such, whether or not the Company would
have the power to indemnify such Person against such liability under the
provisions of this Section. Any such insurance may be procured from any
insurance company designated by the Managing Member, whether such insurance
company is formed under the laws of this state or any other jurisdiction of the
United States or elsewhere.

          e.  Any indemnification of or advance of expenses to a Managing Member
in accordance with this Section, if arising out of a proceeding by or on behalf
of the Company, shall be reported in writing to the Members within a reasonable
time after demand therefor is made.

          f.  For purposes of this Section 8.4, Managing Members shall include a
former Managing Member.

     8.5. Transactions with Company or Otherwise.  A Managing Member shall
          --------------------------------------      
not be required to manage the Company as such Managing Member's sole and
exclusive activity, and any of the Members or Managing Member, or any agent,
servant, or employee of any of the Members or Managing Member, may engage in and
possess any interest in other businesses or ventures of every nature and
description, independently or with other Persons, whether or not directly or
indirectly in competition with the business or purpose of the Company, and
neither the Company nor any of the Members shall have any rights, by virtue of
this Agreement or otherwise, in and to such independent ventures or the income
or profits derived therefrom, or any rights, duties, or obligations in respect
thereof. The Members or Managing Member or any Affiliate of any Member or
Managing Member may lend money to, act as surety for, and transact other
business with the Company, including, without limitation, management or
marketing agreements requiring the Company to pay fees or other compensation
from Company funds and shall have the same rights and obligations with respect
thereto as a Person who is not a Member or Managing Member of the Company,
except that nothing contained in this Section shall be construed to relieve a
Member from any duties to the Company. Without limiting the generality of the
foregoing, the Members acknowledge that an Affiliate of Hilton or Boomtown, or
both, may enter into a management agreement with the Company or a Subsidiary for
management of the Project and that such agreement may provide for management
fees of two percent (2%) of gross revenues and five percent (5%) of EBITDA (as
defined in such management agreement) from the Project.

                                      -12-

 
     8.6. Annual Operating Budget And Members' Additional Capital Contributions
          ---------------------------------------------------------------------
for Operating Deficits.
- ---------------------- 

          a.  The Company shall annually adopt a budget.

          b.  The Managing Member shall prepare a budget in every Fiscal Year.
The budget shall be adopted if Approved. The budget may require Members to make
additional Capital Contributions to remove or prevent any deficits of the
Company, and the Managing Member shall also be entitled to require additional
Capital Contributions from the Members from time to time in the event of
deficits not anticipated in the budget. The Members shall make the additional
Capital Contributions in proportion to the number of Units held in the Company.

     8.7. Failure to Make Required Additional Capital Contributions. If a Member
          ---------------------------------------------------------
fail to make a required additional Capital Contribution ("Noncontributing
Member") then any other Voting Member who contributed its required Capital
Contributions ("Contributing Member") shall have the right to elect to rely on
this section in which event, the following provisions shall apply. Any
Contributing Member may give notice (a "Contribution Notice") to the
Noncontributing Member that the Contributing Member has elected to make all or
any portion of the Noncontributing Member's Capital Contribution and receive an
increase in its percentage ownership interest and number of Units pursuant to
the following formula. The Contributing Member's percentage ownership interest
in the Company shall be increased to the percentage represented by a fraction,
the numerator of which is the sum of the Contributing Member's Initial Capital
Contribution and all additional Capital Contributions by the Contributing
Member, and the denominator of which is the sum of the initial Capital
Contribution and all additional Capital Contributions by all Members. The
Noncontributing Member shall transfer that portion of its Units (the
"Transferred Interest") to the Contributing Member necessary to increase the
Contributing Member's percentage ownership interest in the Company to the amount
calculated in accordance with the preceding sentence. In the event more than one
Contributing Member elects to make the additional Capital Contribution on behalf
of the Noncontributing Member and purchase the Transferred Interest, the
Contributing Members shall make such additional Capital Contribution, and the
Transferred Interest shall be allocated among the Contributing Members, in
proportion to their then existing ownership of Units in the Company. The
Noncontributing Member shall execute and deliver to the Contributing Member(s)
all such documents and instruments as are reasonably necessary or appropriate to
affect such transfer within five (5) days after receipt of the Contribution
Notice and payment of the portion of the additional Capital Contribution being
made by the Contributing Member(s). The Noncontributing Member shall also, upon
the request of the Contributing Member(s), at any time and from time to time,
execute and deliver such other documents and instruments as the Contributing
Member(s) determines are necessary or desirable to transfer ownership, title and
control of the Transferred Interest. The Noncontributing Member shall transfer
the Transferred Interest free of all liens and encumbrances. The provisions of
this Section are intended as the sole remedy of the Members in the event a
Member fails to make an additional Capital Contribution.

8.8.  Repurchase of Transferred Interest.  A Noncontributing Member shall have
      ----------------------------------                                      
the option to repurchase all, but not less than all, of its previously
Transferred Interest(s) at

                                      -13-

 
any time prior to the earlier of (i) the date two years after the date of this
Agreement and (ii) opening of the Project for business to the public (the
"Repurchase Deadline"), for a purchase price (the "Repurchase Price") equal to
the amount of the Noncontributing Member's additional Capital Contribution made
by the Contributing Member together with interest thereon from the date the
additional Capital Contribution is made at the rate of ten percent (10%) per
annum. The Noncontributing Member shall exercise the foregoing option by written
notice to the Contributing Member at least ten (10) days prior to the Repurchase
Deadline. The Transferred Interest(s) shall be assigned to the Noncontributing
Member within ten (10) days after receipt of notice of the exercise of the
option to repurchase by an appropriate instrument of assignment and upon payment
of the Repurchase Price to the Contributing Member in cash or cash equivalent.
The Noncontributing Member shall be responsible for any costs or fees associated
with its repurchase of the Transferred Interest(s). Upon repurchase of all of
its Transferred Interest(s) pursuant to this Section such that its Original
Percentage is restored, any Units of the Noncontributing Member converted to 
Non-Voting Units shall be converted back to Voting Units and such 
Noncontributing Member shall again become a Managing Member.

     8.9.  Management Disputes.  During any time that the Managing Member 
           -------------------
consists of more than one Person, in the event of any dispute arising under or
in connection with management of the Company, and if such dispute cannot be
settled through direct discussions, the Persons who are the Managing Member
shall first endeavor to settle the dispute in an amicable manner by mediation
administered by the American Arbitration Association under its Commercial
Mediation Rules. Mediation shall be conducted for a period of thirty (30) days
after selection of a mediator in accordance with the Commercial Mediation Rules,
and may be initiated by written notice of one Managing Member to the other. In
the event of a dispute relating to the requirement of an additional Capital
Contribution only, and after expiration of the period for mediation without a
resolution of the dispute, either Person may require that the dispute be settled
by arbitration held in Las Vegas, Nevada in accordance with the Commercial
Arbitration Rules of the American Arbitration Association then in effect and the
following procedures, which procedures shall control in the event of conflict
with such Commercial Arbitration Rules:

     (a)   Within ten (10) days after notice from one Person to the other that
           it has elected that the dispute be arbitrated, both Persons shall
           contact the American Arbitration Association to commence selection of
           the arbitrators in accordance with their Commercial Arbitration
           Rules. The panel to be appointed shall consist of three neutral
           arbitrators.

     (b)   Subject to the time restrictions set forth below, the arbitrators
           shall conduct the arbitration in such manner (including the allowance
           of such discovery as the arbitrators determine appropriate under the
           circumstances) and on such a schedule as the arbitrators deem to be
           fair and reasonable and to provide each party with an adequate
           opportunity to present and support its position. The arbitrators
           shall resolve the dispute and give the parties written notice of
           their decision, with the reasons therefore set out in full, within
           thirty (30) days after the arbitrators' selection and shall have ten
           (10) days thereafter to reconsider and modify such decision if any
           party so requests. Thereafter the 

                                      -14-

 
           arbitrators' decision shall be final, binding, and nonappealable. The
           arbitrators shall be bound by the terms of this Agreement and
           applicable law.

     (c)   The arbitrators shall have authority to award relief under legal or
           equitable principles, including interim and preliminary relief. The
           arbitrators shall allocate the costs of the arbitration, including
           the arbitrators' fee, between the parties upon such basis as the
           arbitrators deem equitable. The arbitrators shall also award such
           incidental recovery, such as interest, as required by this Agreement.

     (d)   Judgment upon the award rendered by the arbitrators may be entered in
           any court having personal and subject matter jurisdiction.

     (e)   If for any reason whatsoever the written decision and award of the
           arbitrators shall not be rendered within the time limits set forth in
           this Section 8.8, either party may apply to any court having
           jurisdiction by action, proceeding or otherwise (but not by a new
           arbitration proceeding) as may be proper to determine the question in
           dispute consistently with the provisions of this Agreement.

                       RIGHTS AND OBLIGATIONS OF MEMBERS
                       ---------------------------------

     9.1.  Limitation of Liability.  Each Member's liability shall be limited as
           -----------------------
set forth herein and in the Act and other applicable law.

     9.2.  Company Debt Liability Indemnity.
           -------------------------------- 

           a.  A Member will not personally be liable for any debts or losses of
the Company, except as provided in the Act.

           b.  Except to the extent due to such Member's default hereunder or
under the Articles of Organization, the Company agrees to indemnify, pay,
protect and hold harmless any Member (on demand and to the satisfaction of the
Member) from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, proceedings, costs, expenses and
disbursements of any kind or nature whatsoever (including, without limitation,
all reasonable costs and expenses in connection therewith of investigation,
defense, appeal and -- provided that consent to settlement from all Members is
obtained, which consent shall not be unreasonably withheld -- expenses of
settlement of any and all suits, actions or proceedings instituted against the
Member), which may be imposed on, incurred by, or asserted against the Member
(solely as a result of such Member being a Member) in any way relating to any
agreement, liability, commitment, expense or obligation of the Company. If any
such action, suit or proceeding shall be pending or threatened against a Member,
the Member shall have the right to employ, at the expense of the Company,
separate counsel of such Member's choice in such action, suit or proceeding, and
the Company shall advance the reasonable expenses of such Member in connection
therewith. The satisfaction of the obligations of the Company under this Section
shall be from and limited to the assets of the Company and no Member shall have
any personal 

                                      -15-

 
liability on account thereof. The foregoing rights of indemnification are in
addition to and shall not be a limitation of any rights that may be provided in
the Act.

     9.3.  List of Members.  Upon written request of any Member, the Managing
           ---------------
Member shall provide a list showing the names, addresses and Units of the
Members in the Company.

     9.4.  Liability of a Member to the Company.
           ------------------------------------ 

           a.  When a Member has rightfully received the return in whole or in
part of such Member's Capital Contribution, the Member is nevertheless liable to
the Company for any sum, not in excess of the return of its Capital Contribution
with interest at the rate provided for judgments under the laws of the State of
Nevada, necessary to discharge the Company's liability to all creditors of the
Company who extended credit or whose claims arose before the return of such
Member's Capital Contribution.

           b.  When a Member has received a distribution wrongfully conveyed by
the Company, the Member shall hold such distribution as trustee for the Company.

                                  ARTICLE 10
                                  ----------
                             TRANSFER OF INTERESTS
                             ---------------------

     10.1. Right to Pledge. Every Member's Interest may be pledged to secure any
           ---------------
borrowing of a Member or its Affiliates.

     10.2.  Admission of Substituted Member. Members holding Voting Units may
            -------------------------------
freely assign or transfer their Member's Interests among themselves or to
Affiliates of Members holding Voting Units. If a Member transfers its Member's
Interest to a Person who is not already a Member or an Affiliate of a Member
holding Voting Units (or transfers title as a result of exercise of rights under
a security interest), and Members holding at least 80% of the then outstanding
Voting Units approve of such proposed transfer or assignment, the transferee or
assignee of the Member's Interests shall become a "Substituted Member" (as such
term is defined below). If Members holding at least 50% of the then outstanding
Voting Units do not approve of such transfer or assignment, the transferee or
assignee of the Member's Interest shall have no right to participate in the
management of the business and affairs of the Company, to vote its Units, or to
be admitted as a Member, but shall only be entitled to receive the share of
profits, losses and distributions, to which the transferring Member would
otherwise be entitled. As a condition to the receipt of same, the transferee or
assignee may be required by the Managing Member to pay any Capital Contributions
to which the transferor or assignor would have been liable. A "Substituted
Member" is a Person admitted to all the rights of a Member. The Substituted
Member has all the rights and powers and is subject to all the restrictions and
liabilities of his assignor whether accrued prior to or after the date of
substitution (including, without limitation, the right to allocations of profits
under Section 1.2(a) of Appendix 1 to the extent attributed to the interest
acquired by the Substituted Member), except that the substitution of the
assignee does not release the assignor from liability to the Company. In any
event, no transfer of a Member's Interest in the Company (including the transfer
of any right to receive or share in profits, losses, or distributions) shall be
effective unless and until written notice (including 

                                      -16-

 
the name and address of the proposed transferee or assignee and the date of such
transfer) has been provided to the Company and the nontransferring Member(s).
Every Person before becoming a Substituted Member must assume this Agreement in
writing.

     No Member shall be entitled to transfer less than 100% of his Member's
Interest except in the case of a transfer between Members.

     10.3.  Denial. If at any time (a) a Member or any Person associated in any
            ------
way with a Member (collectively, the "Defaulting Member") is denied a license,
found unsuitable, or is denied or otherwise unable to obtain any other License
or with respect to the Project or any other gaming operation elsewhere in the
world by a Gaming Authority or is required by any Gaming Authority to apply for
a License and does not apply within any required time limit (including
extensions, if any), withdraws any application for a License other than upon a
determination by the applicable Gaming Authority that such License is not
required, and if the result of the foregoing has or would have an adverse effect
on the Company, the Project, any other Member (referred to herein as
"Nondefaulting Member") or any Affiliate of a Nondefaulting Member or does or
would materially delay obtaining any License affecting the Company, any
Affiliate of the Company, the Project, a Nondefaulting Member or its Affiliate,
or (b) any Gaming Authority commences or threatens to commence any suit or
proceeding against the Company, its Affiliates, the Project, a Nondefaulting
Member or its Affiliates or to terminate or deny any right or License of the
Company, its Affiliate, the Project, a Nondefaulting Member or its Affiliate
because of this Agreement or the relationship to the Defaulting Member (all of
the foregoing events described in (a) and (b) above are collectively referred to
as a "Denial"), said Denial shall constitute a default by the Defaulting Member
and the Nondefaulting Members may pursue any available remedies.

     Without limitation on the foregoing, if the Denial may be cured by the
replacement of one or more individuals as shareholders, officers, employees or
directors of the Defaulting Member, then the Defaulting Member shall have up to
sixty (60) days from such Denial (but not more than twenty (20) days less than
the period, if any, as may be allowed by the Gaming Authorities to effect such
cure), to replace the disapproved individual with someone, or sell his Member's
Interest to someone acceptable to the Gaming Authorities and approved by the
Members as set forth above in this Article 10.  If a cure of the type described
in the preceding sentence is not feasible or permitted, or if not effected
within the time periods prescribed above, the Voting Members who are not
Defaulting Members shall have the right to purchase such Defaulting Member's
Interest, prorata according to the purchasing Members Units in the Company, at a
purchase price (the "Purchase Price") equal to fifty percent (50%) of the total
unreturned Capital Contributions of such Defaulting Member, by giving written
notice (the "Purchase Notice") to the Defaulting Member.  Payment of the
Purchase Price shall be by execution and delivery of a promissory note by the
purchasing Member(s) to the Defaulting Member, amortized and payable over five
(5) years from the date of such note, prepayable at any time at the option of
the purchasing Member(s) without penalty, with monthly payments, and bearing
interest at the rate announced by Bank of America, NT&SA as its prime rate of
interest from time to time, or if Bank of America NT&SA no longer announces a
prime rate of interest, a substitute financial institution acceptable to the
purchasing Member(s).  The Defaulting Member shall execute and deliver to the
purchasing Member(s) all such documents and instruments as are reasonably
necessary or appropriate to effect such transfer within five (5) days after
receipt 

                                      -17-

 
of the Purchase Notice and the purchasing Member(s) shall deliver this
promissory note(s) representing the Purchase Price concurrently with such
delivery. The Defaulting Member shall also, upon the request of the purchasing
Member(s), at any time and from time to time, execute and deliver such other
documents and instruments as the purchasing Member(s) determines are necessary
or desirable to transfer ownership, title and control of such Defaulting
Member's Interest. The Defaulting Member shall transfer his Member's Interest
free of all liens and encumbrances.

certain circumstances, involving termination of the Stock Agreement.  The
Members hereby agree that no consent or approval by any Member is required in
connection with the transfer of Shares or any other right in the Project in
compliance with the Stock Agreement.  Each Member shall take all necessary
action to comply with the provisions of Section 5.02.3 of the Stock Agreement,
including, without limitation, the transfer of its Member's Interest to Seller
in the event and to the extent required pursuant to such section.

     10.7  Public Trading.  No Member shall transfer its Member's Interest if
           --------------                                                    
such transfer could cause the Company to be deemed a "publicly traded
partnership," as that term is defined in Section 7704 of the Code.

business of the Company, including without limitation the operation of the
Company's Property, is continued by the consent of Members holding a majority in
interest in the Company within ninety (90) days after the occurrence of such

     11.3.  Winding Up.  Except as provided by law, upon dissolution, each
            ----------
Member shall look solely to the assets of the Company for the return of its

distribution of its assets shall be conducted exclusively by the Managing
Member, who are hereby authorized to take all actions necessary to accomplish
such distribution, including without limitation, selling any Company assets the
Managing Member deem necessary to accomplish such distribution, including
without limitation, selling any Company assets the Managing Member deem
necessary or appropriate to sell. In the discretion of the Managing Member, a
pro rata portion of the accounts that otherwise would be distributed to the
Members under this Article may be withheld to provide a reasonable reserve for
unknown or contingent liabilities of the Company.

other parties with whom the Company regularly conducts business, and shall
publish notice of dissolution in a newspaper of general circulation in each
place in which the Company generally conducts business.

temporary (but not proposed) regulations, promulgated under the Code.

          1.2.  Allocation of Profits. After giving effect to the special
                ---------------------
allocations set forth in Section 1.4 hereof, Profits for any Fiscal Year shall
be allocated as follows:

                a.  Profits shall first be allocated to the Members in
proportion and up to the amount which, when added to aggregate profits
previously allocated under this Section 1.2(a) equals the aggregate amount of
losses allocated to the Members under Section 1.3(b) hereof.

                b.  Thereafter, profits shall be allocated to each Member pro
rata in proportion to the ratio of that Member's Units to all other Units
outstanding.

          1.3.  Allocation of Losses. After giving effect to the special
                --------------------
allocations set forth in Section 1.4 hereof, Losses for any Fiscal Year shall be
allocated as follows:

                a.  Subject to the limitations in Section 1.3(b) hereof, Losses
shall be allocated to each Member pro rata in proportion to the ratio of that
Member's Units to all other Units outstanding.

                b.  Losses allocated to any Member pursuant to this Agreement
shall not exceed the maximum amount of Losses that may be allocated without
causing such Member to have an Adjusted Capital Account Deficit at the end of
the Fiscal Year for which the allocation is made. Any losses not allocated to a
Member as a result of the preceding sentence shall be allocated to other Members
("Allocable Members") for whom such allocation would not cause an Adjusted
Capital Account Deficit at the end of the Fiscal Year for which the allocation
is made pro rata in proportion to such Allocable Member's Units, but only to the
extent that such allocation does not cause such Allocable Member to have an
Adjusted Capital Account Deficit at the end of the Fiscal Year for which the
allocation is made. If there are no Allocable Members, this section 1.3(b)
limitation shall not apply and Losses shall be allocated to each Member pro rata
in proportion to the ratio of that Member's Units to all other Units
outstanding.

     1.4. Special Provisions.
          ------------------ 

          a.  Minimum Gain Chargeback. Notwithstanding any other provision of
              -----------------------
this Agreement, if there is a net decrease in Membership Minimum Gain (as
defined in 

                           Tax Accounting Procedures

                                      -25-

 
Regulation Section 1.704-2(d)) during any Fiscal Year, then each Member shall be
allocated such amount of income and gain for such year (and subsequent years, if
necessary) determined under and in the manner required by Regulation Section
1.704-2(f) as is necessary to meet the requirements for a minimum gain
chargeback as provided in that Regulation.

          b.  Member Nonrecourse Debt Minimum Gain Chargeback. Notwithstanding
              -----------------------------------------------
any other provision of this Agreement, if there is a net decrease in Member
Nonrecourse Debt Minimum Gain (as defined in accordance with Regulation Section
1.704-2(i)(3)) attributable to a Member Nonrecourse Debt (as defined in
Regulation Section 1.704-2(b)(4)) during any Fiscal Year, any Member who has a
share of the Member Nonrecourse Debt Minimum Gain attributable to such Member
Nonrecourse Debt determined in accordance with Regulation Section 1.704-2(i)(5)
shall be allocated such amount of income and gain for such year (and subsequent
years, if necessary) determined under and in the manner required by Regulation
Section 1.704-2(i)(4) as is necessary to meet the requirements for a chargeback
of Member Nonrecourse Debt Minimum Gain as is provided in that Regulation.

          c.  Qualified Income Offset. If a Member unexpectedly receives any
              -----------------------
adjustment, allocation or distribution described in Regulation Section 1.704-
1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain shall be
specifically allocated to such Member in an amount and manner sufficient to
eliminate, to the extent required by the Regulations, the Adjusted Capital
Account Deficit of such Member as quickly as possible, provided that an
allocation pursuant to this Subsection shall be made only if and to the extent
that such Member would have an Adjusted Capital Account Deficit after all other
allocations provided for in Sections 1.2, 1.3 and this Section 1.4 of this
Appendix have been made without giving effect to this Subsection (c).

          d.  Gross Income Allocation. In the event any Member has a deficit
              -----------------------
Capital Account at the end of Fiscal Year which is in excess of the sum of (i)
the amount such Member is obligated to restore pursuant to this Agreement, and
(ii) the amount such Member is deemed to be obligated to restore pursuant to
Regulations 1.704-2(g)(1) and 1.704-2(i)(5), each such Member shall be specially
allocated items of Company income and gain in the amount of such excess as
quickly as possible, provided that an allocation pursuant to this Subsection
shall be made only if and to the extent that such Member would have a deficit
Capital Account after all other allocations provided for in Sections 1.2, 1.3,
and this Section 1.4 of this Agreement have been made without giving effect to
Subsection (c) immediately above and this Subsection (d).

          e.  Nonrecourse Deductions. Nonrecourse Deductions (as determined
              ----------------------
under Regulation Section 1.704-2(c)) for any Fiscal Year shall be allocated
among the Members in proportion to their Units.

          f.  Member Nonrecourse Deductions. Any Member Nonrecourse Deductions
              -----------------------------
(as defined under Regulation Section 1.704-2(i)(2)) shall be allocated pursuant
to Regulation Section 1.704-2(i)(1) to the Member who bears the economic risk of
loss with respect to the "Member Nonrecourse Debt" (as defined in Regulation
Section 1.704-2(b)(4)) to which it is attributable.

                           Tax Accounting Procedures

                                      -26-

 
          g.  Code Section 754 Adjustment. To the extent that an adjustment to
              ---------------------------
the Basis of any asset pursuant to Code Section 734(b) or Code Section 743(b) is
required to be taken into account in determining Capital Accounts as provided in
Regulation Section 1.704-1(b)(2)(iv)(u), the adjustment shall be treated (if an
increase) as an item of gain or (if a decrease) as an item of loss, and such
gain or loss shall be allocated to the Members consistent with the allocation of
the adjustment pursuant to such Regulation.

          h.  Purpose and Application. The purpose and the intent of the special
              -----------------------
allocations provided for in this Section are to comply with the provisions of
Regulation Sections 1.704-1(b) and 1.704-2, and such special allocations are to
be made so as to accomplish that result. However, to the extent possible, the
Managing Member, in allocating items of income, gain, loss, or deduction among
the Members, shall take into account the special allocations in such a manner
that the net amount of allocations to each Member shall be the same as such
Member's distributive share of Profits and Losses would have been had the events
requiring the special allocations not taken place. The Managing Member shall
apply the provisions of this Section in whatever order the Managing Member
reasonably believe will minimize the effect of the special allocations.

     1.5. General Provisions.
          ------------------ 

          a.  Except as otherwise provided in this Agreement, the Members'
distributive shares of all items of Company income, gain, loss, and deduction
are the same as their distributive shares of Profits and Losses.

          b.  The Managing Member shall allocate Profits, Losses, and other
items properly allocable to any period using any method permitted by Code
Section 706 and the Regulations thereunder.

          c.  To the extent permitted by Regulations Section 1.704-2(h) and
Section 1.704-2(i)(6), the Managing Member shall endeavor to avoid treating
distributions as being from the proceeds of a Nonrecourse Liability (as defined
in Regulation Sections 1.704-2(b)(3)) or a Member Nonrecourse Debt.

          d.  If there is an increase or decrease in one or more Unit(s) in the
Company during a Fiscal Year, each Member's distributive share of Profits or
Losses or any item thereof for such Fiscal Year shall be determined by any
method prescribed by Code Section 706(d) or the Regulations thereunder that
takes into account the varying Members' Interests in the Company during such
Fiscal Year.

          e.  The Members agree to report their shares of income and loss for
federal income tax purposes in accordance with the provisions of this Agreement.

     1.6. Code Section 704(c) Allocations. Solely for federal income tax
          -------------------------------
purposes and not with respect to determining any Member's Capital Account,
distributive shares of Profits, Losses, other items, or distributions, a
Member's distributive share of income, gain, loss, or deduction with respect to
any Property (other than money) contributed to the Company, or with respect to
any Property the Asset Value of which was determined as provided in this
Agreement upon the acquisition of one or more additional Units in the 

                           Tax Accounting Procedures

                                      -27-

 
Company by a new Member or existing Member in exchange for a Capital
Contribution, shall be determined in accordance with Code Section 704(c) and the
Regulations thereunder or with the principles of such provisions.

     1.7.  Allocations Relating to Taxable Issuance of Units. Any income, gain,
           -------------------------------------------------
loss or deduction realized by the Company as a direct or indirect result of the
issuance of a Unit by the Company (the "Issuance Items") shall be allocated
among the Members, so that, to the extent possible, the net amount of such
Issuance Items, together with all other allocations under this Agreement to each
Member, shall be equal to the net amount that would have been allocated to each
such Member if the Issuance Items had not been realized.

     1.8.  Curative Reallocations Regarding Payments to Members. To the extent
           ----------------------------------------------------
that compensation paid to any Member by the Company ultimately is not determined
to be a guaranteed payment under Code Section 707(c) or a payment other than in
his capacity as a Member pursuant to Code Section 707(a), the Member shall be
specially allocated gross income of the Company in an amount equal to the amount
of such compensation, and the Member's Capital Account shall be adjusted to
reflect the payment of such compensation. If the Company's gross income for a
Fiscal Year is less than the amount of such compensation paid in such year, the
Member shall be specially allocated gross income of the Company in the
succeeding year or years until the total amount so allocated equals the total
amount of such compensation.

     1.9.  Division Among Members. If there is a change in a Member's Interest
           ----------------------
in the Company during a Fiscal Year, any distributions thereafter shall be made
so as to take into account the varying Units of the Members during the period to
which the distribution relates in any manner chosen by the Managing Member that
is provided in Code Section 706(d) and the Regulations thereunder.

     1.10. Special Basis Adjustment.  At the request of either the transferor
           ------------------------
or transferee in connection with a transfer of a Member's Interest in the
Company, the Managing Member may, in their sole discretion, cause the Company to
make the election provided for in Code Section 754 and maintain a record of the
adjustments to Basis of Property resulting from that election. Any such
transferee shall pay all costs incurred by the Company in connection with such
election and the maintenance of such records.

     1.11. Tax Matters Member.
           ------------------ 

           a.  ____________________ is hereby designated the Tax Matters Member
(as defined in the Code) on behalf of the Company.

           b.  Without the consent of the Members holding at least 60% of the
Voting Units, the Tax Matters Member shall have no right to extend the statute
of limitations for assessing or computing any tax liability against the Company
or the amount of any Company tax item.

           c.  If the Tax Matters Member elects to file a petition for
readjustment of any Company tax item (in accordance with Code Section 6226(a))
such petition shall be

filed in the United States Tax Court unless the Members holding at least 60% of
the Voting Units agree otherwise.

           d.  The Tax Matters Member shall, within ten (10) business days after
receipt thereof, forward to each Member a photocopy of any correspondence
relating to the Company received from the Internal Revenue Service. The Tax
Matters Member shall, within ten (10) business days thereof, advise each Member
in writing of the substance of any conversation held with any representative of
the Internal Revenue Service.

           e.  Any reasonable costs incurred by the Tax Matters Member for
retaining accountants and/or lawyers on behalf of the Company in connection with
any Internal Revenue Service audit of the Company shall be expenses of the
Company. Any accountants and/or lawyers retained by the Company in connection
with any Internal Revenue Service audit of the Company shall be selected by the
Tax Matters Member and the fees therefor shall be expenses of the Company.

     1.12. Deemed Liquidation.  If no Dissolution Event has occurred, but the
           ------------------                                                
Company is deemed liquidated for federal income tax purposes within the meaning
of Regulation Section 1.704-(b)(2)(ii)(g), the Company shall not be wound up and
dissolved but its assets and liabilities shall be deemed to have been
distributed to the Members and contributed to a new Company which shall operate
and be governed by the terms of this Agreement.
