                                       1


 
          "ACQUISITION FINANCE" means any and all Debt Financing Facilities or
          arrangements to which MGM Grand Australia is a party but only to the
          extent the proceeds of which are used to satisfy the "Purchase Price"

               with Clause 3.2(a) or in the case of a person nominated by an
               Option Holder pursuant to Clause 3.2(b), opposite the name of the
               Option Holder who nominates such person; and

          (b)  in relation to the Put Option Shares; the pro rata number of

               percentage of all MGMGA Shares held by the Option Holders at the
               time any such calculation is made.

          "BUSINESS DAY" means:

          (a)  for the purposes of Clause 16.6(c) a day on which banks are open
               for business in the place of receipt of the notice or

          Holders pursuant to Clause 3 for the Option Holders to require MGM

                                       2

 
          "CALL OPTION CONSIDERATION" means the total amount payable for all of
          the Call Option Shares and determined in accordance with the formula
          contained in Schedule 2;

          "CALL OPTION EXERCISE DATE" the date on which the Call Option is 
          exercised in accordance with Clause 3;

          "CALL OPTION PERIOD" means the period commencing on the second

                         create any interest therein except as expressly
                         permitted by this Deed; and

                    (ii) in the case of MGM Grand Australia, register any
                         transfer or recognise or give effect to any matter
                         referred to in Clause 4.1(e)(i);

               (f)  permit any act that would cause
                    
                    (i)  MGM Grand Diamond or MGM Grand Australia to cease to be
                         a Subsidiary of MGMG; or

                    (ii) a Subsidiary of MGM Grand Australia, whether such 
                         Subsidiaries exists at or after the date of this Deed, 
                         to cease to be a Subsidiary of MGM Grand Australia;

                    provided that nothing herein shall preclude the liquidation
                    and/or reorganisation of a Subsidiary as long as MGM Grand
                    Australia retains the direct or indirect beneficial
                    ownership or control of all of the material assets and
                    business thereof;

               (g)  permit any act to occur which would result in the MGM Grand
                    Australia Group not being entitled to at least Eighty five
                    per cent (85%) of the beneficial interest in the Territory
                    Property Trust and the underlying property currently held by
                    the Territory Property Trust; or

               (h)  change the auditor of MGM Grand Australia if the new auditor
                    is not one of the 6 largest internationally recognised
                    accounting firms.

          4.2  In the event that MGM Grand Diamond proposes to enter into a
               transaction prior to Call Option Completion, which if entered
               into after Call Option Completion, would bring into operation
               Part 10 or Part 11 of Schedule 4, MGM Grand Diamond and the
               Option Holders shall have the rights provided for in such Parts
               notwithstanding that Call Option Completion has not occurred.
               Additionally, to the extent the exercise of such rights would
               require a payment by MGM Grand Diamond or a third party to the
               Option Holders in connection with the acquisition of the Option
               Holders' rights to acquire the Call Option Shares, such payment
               shall be determined as if the Call Option Shares were outstanding
               but there shall be deducted from the consideration payable to the
               Option Holders an amount equal to its relevant proportion of the
               Call Option Consideration, which such amount shall be retained by
               MGM Grand Diamond or paid to MGM Grand Diamond by such third
               party, as the case may be. However, if the Call Option
               Consideration is a negative amount then MGM Grand Diamond shall
               pay to the Option Holders their relevant proportion of the
               Rebate.

          shall enure for the benefit of the party in whose favor it is given.

6.   UNDERTAKINGS
     ------------

     6.1  DURATION
          --------
     
          During the period commencing on the date hereof and expiring at the
          end of the Call Option Period and, if the Call Option has been
          exercised, thereafter until either:-

          (a)  a Listing of any Equity Securities of MGM Grand Australia has 
               occurred; or

                                      17

               6.2, 6.5, 6.6 and 6.7 shall cease to apply immediately prior to
               the official consent to such Listing being obtained from the
               relevant stock exchange and in the case of Clauses 6.3, 6.4 and
               6.8 shall cease to apply to the extent only that any of the
               provisions contained in Clauses 6.3, 6.4 or 6.8 are incompatible
               with such Listing or any applicable laws, rules or regulations
               applying to MGM Grand Australia as a consequence of such Listing.
               For the avoidance of doubt such provision shall not be
               incompatible by reason only of their inability to be included in
               the articles of association of MGM Grand Australia as and from
               Listing.

          6.2  FUNDING OF MGM GRAND AUSTRALIA

                          ensure that all members of MGM Grand Australia Group

                          (A) all gaming losses and other deficiencies in 
                              working capital of the Casino; and

                              refurbishment of the Casino.

                    (ii)  Nothing in this Clause 6.2 shall limit or restrict in
                          any way the ability of MGM Grand Australia or MGM
                          Grand Australia Group to cease trading or enter into
                          voluntary liquidation.

               (b)  The funding to be provided to or procured by the MGM Grand 
                    Australia Group, shall be limited to:-

                    (i)  (SHAREHOLDER LOANS) loans made by MGM Grand Diamond or
                         an Associate of MGM Grand Diamond to MGM Grand
                         Australia Group which are unsecured and subordinated to
                         the claims of all other creditors of the MGM Grand
                         Australia Group. MGM Grand Diamond or its Associate (as
                         the case may be) shall be entitled to receive interest
                         on such loans to the extent only that such interest
                         reflects its actual external cost of the funds
                         ("Actually External Cost") without regard to whether or
                         not MGM Grand Diamond or its Associate actually borrows
                         funds specifically for this purpose. Administrative
                         costs within the MGM Grand Group and the application of
                         any withholding taxes in Australia shall not be an
                         Actual External Cost of MGM Grand Diamond for the
                         purpose of this Clause. Prior to making any advance to
                         MGM Grand Australia Group, MGM Grand Diamond and the
                         Nominated Option Holder shall use good faith efforts to
                         agree upon the Actual External Cost to MGM Grand
                         Diamond of such funds, which in any event shall not be
                         less than

                                      18

 
                          the aggregate of One per cent (1%) plus LIBOR for
                          loans of comparable maturities. MGM Grand Diamond
                          shall provide to the Nominated Option Holder
                          sufficient information to enable it to verify by
                          independent calculation the Actual External Cost. If
                          MGM Grand Diamond and the Nominated Option Holder can
                          not agree as to the Actual External Cost within 15
                          Business Days of the Nominated Option Holders first
                          being notified of the proposed advance then the Actual
                          External Cost shall be the cost certified by an
                          independent expert appointed pursuant to Clause 9.1.
                          Until such time as the independent expert has
                          certified, the Actual External Cost. MGM Grand Diamond
                          or its Associate may advance the funds to MGM Grand
                          Australia Group at the interest rate MGM Grand Diamond
                          believes reflects the Actual External Cost but subject
                          to an adjustment being made up or down to principal
                          and/or interest (at the election of the relevant
                          member of MGM Grand Australia Group) in the event that
                          the independent expert certifies a figure more than
                          Fifty (50) basis points higher or lower than the rate
                          then being imposed by MGM Grand Diamond;

                    (ii)  (BANKS) by external third party lenders on the best
                          terms then available, which terms shall reflect that
                          MGMG and/or MGM Grand Diamond is prepared to provide a
                          guarantee for any such advances made direct to a
                          member of the MGM Grand Australia Group, where
                          necessary;

                    (iii) (EQUITY) from equity subscriptions by MGM Grand
                          Diamond or any member of the MGM Group or any Related
                          Body Corporate for MGMGA Shares, with the prior
                          written consent of the Nominated Option Holder, which
                          shall not be unreasonably withheld if such equity
                          subscription shall not dilute or adversely affect the
                          legal and commercial benefit of the Call Options.

                    one or more of:-

                    (i)  the MGM Group on the one hand, and 

                    (ii) the Option Holder Group on the other hand, as the case 
                         may be,

                    in the Northern Territory of Australia, shall be conducted 
                    solely through the MGM Grand Australia Group.

                                      19

 
               (b)  The undertakings contained in Clause 6.3(a) shall only apply
                    until the earlier of:-

                    (i)  the expiry of the Call Option Period, or if the Call
                         Option has been exercised, until such time as the

                    (ii) no member of the MGM Grand Australia Group holds an

                         gaming in the Northern Territory of Australia.

          6.4  NOMINEE DIRECTORS
               -----------------

               (a)  (i)  Prior to Call Option Completion, the Option Holders

                         remove and replace such appointee. Where there is more
                         than one Option Holder, from time to time, the right to
                         appoint and remove directors shall be exercised by the
                         Nominated Option Holder in writing.

               (b)  (i)  As and from Call Option Completion the Option Holders
                         shall have the right, so long as any of them hold MGMGA
                         Shares, to appoint and remove directors on each and
                         every Relevant Board. The number of directors that may
                         be appointed and removed shall be determined by
                         reference to the aggregate percentage of MGMGA Shares
                         held by the Option Holders in accordance with the
                         formula contained in Clause 6.4(b)(ii). Where there is
                         more than one Option Holder, from time to time, the
                         right to appoint and remove directors shall be
                         exercised in writing by the Nominated Option Holder.

                    (ii) Subject to Clause 6.4(b)(iii) the minimum number of
                         Nominee Directors that may be appointed and removed by
                         the Option Holders, from time to time, shall be
                         determined by applying the percentage in the right hand
                         column shown opposite the relevant aggregate holding of
                         the Option Holders in the left hand column, to the
                         total number of directors of the Relevant Board.

                                      20

 

 
                         AGGREGATE PERCENTAGE OF       MINIMUM PERCENTAGE OF
                         MGMGA SHARES HELD BY          DIRECTORS OF RELEVANT
                         OPTION HOLDERS                BOARD TO BE APPOINTED
                                                       OR REMOVED
                                                      
                         20%-22.5%                     20%
                         less than 20%                 Nil
 


                         Where the calculation results in a fraction, then it
                         shall be rounded up to the next whole number. For the
                         avoidance of doubt the Option Holders shall be entitled
                         to appoint and remove at least one director and remove
                         such director so long as they collectively own at least
                         Twenty per cent 20% of the issued MGMGA Shares.

                   (iii) If the Option Holders cease collectively to hold a
                         minimum of Twenty per cent (20%) of the issued MGMGA
                         Shares other than by reason of transfer by any of the
                         Option Holders of any of their MGMGA Shares then for
                         the purposes of Clause 6.4(b)(ii) the aggregate
                         percentage of MGMGA Shares held by the Option Holders
                         shall be determined as if no MGMGA Shares were issued
                         after Call Option Completion.

               (c)  Any Nominee Director appointed by the Option Holders shall
                    be deemed to be the nominee of the Option Holders. The
                    appointment and removal of such director or directors (as
                    the case may be) shall take effect immediately upon receipt
                    of the relevant notices from the Nominated Option Holder
                    (subject to a consent to act as director from the proposed
                    Nominee Directors being attached to the notice). Any
                    proposed new appointment shall be communicated by the Option
                    Holders to MGM Grand Australia or the relevant body where
                    possible, at least Fourteen (14) days in advance. Any such
                    director shall not be appointed unless he or she
                    demonstrates to the reasonable satisfaction of MGM Grand
                    Australia that he or she satisfies all applicable
                    requirements concerning governmental approvals, licences and
                    good standing. If in the opinion of MGM Grand Australia the
                    Nominee Director may cause or contribute to any Government
                    or Minister including without limitation the Government or
                    relevant Minister of the Northern Territory adversely
                    varying, revoking, cancelling or not renewing the Casino
                    Licence, then such Nominee Director shall be removed
                    forthwith by the Option Holders.

               (d)  A Nominee Director shall be entitled to appoint and remove
                    an alternate from time to time. A Nominee Director shall
                    also be entitled to the same level of remuneration payable
                    to other non-executive directors and reimbursement, in full,
                    for all travelling, hotel and associated


                                      21

 
                    expenses reasonably incurred by him in attending board
                    meetings or in relation to the business of the relevant
                    company, it being understood that in order to minimise the
                    incurring of such expenses, it is anticipated that non-
                    resident directors will, for the most part, participate in
                    board meetings by telephone, closed circuit television or
                    other electronic means of video or audio-visual
                    communication.

               (e)  All directors of a Relevant Board shall have one vote,
                    unless they are also the alternate for another director.
                    For the avoidance of doubt the Chairman of the Relevant
                    Board shall not have a casting vote in addition to his
                    deliberative vote.

               (f)  It is expressly agreed and acknowledged that it may be in
                    the best interests of all the relevant members of MGM Grand
                    Australia Group for such director to take into account and
                    act in such manner as he believes best protects the
                    interests of the Option Holders pursuant to this Deed.
                    However, nothing in this Clause shall in any way fetter the
                    discretion of any director to act in any manner he deems
                    fit, including in a manner which may not be in the best
                    interests of the Option Holders, it being acknowledged that
                    all directors, however selected, are subject to fiduciary
                    obligations under applicable law.

               (g)  In respect of each member of the MGM Grand Australia Group,
                    to which he has been appointed, each Nominee Director shall
                    be provided with adequate notice of all meetings of
                    directors and be supplied with proper and full agendas and
                    supporting papers. Notwithstanding anything contained in the
                    constituent documents of each member of the MGM Grand
                    Australia Group, no director's meeting shall be quorate
                    unless:-

                    (i)   at least one Nominee Director or his alternate 
                          attends,

                    (ii)  all of the Nominee Directors waive their right to 
                          attend; or

                    (iii) having been given at least Five (5) Business Days
                          prior proper notice no Nominee Director is present but
                          a majority of directors entitled to receive notice of
                          such meeting are present.

               (h)  Meetings may be in person or by contemporaneous link up by
                    telephone closed circuit television or other electronic
                    means of audio or audio visual communication, or any
                    combination thereof. No business shall be discussed at a
                    meeting of the Relevant Board, without the consent of the
                    Nominee Directors unless it has been adequately included in
                    the agenda that accompanied the notice of meeting.

               (i)  Subject to Clause 10 and Clause 15 of the Deed:

                    (i)   each member of the MGM Grand Australia Group will
                          prepare and provide management information and reports
                          to its directors

                                      22

 
                          sufficient for the efficient operation of the relevant
                          member of the MGM Grand Australia Group; and

                    (ii)  Nominee Directors shall have the right to visit and
                          inspect any of the property of the MGM Grand Australia
                          Group, to inspect and take copies of all documents
                          relating to the MGM Grand Australia Group, including
                          without limiting the generality of the foregoing its
                          books of account, and to discuss its affairs, finances
                          and accounts with any of the officers of the MGM Grand
                          Australia Group or its auditors, at all reasonable
                          times and as often as such person may reasonably
                          request.

               (j)  Subject to Clause 10 and Clause 15 of the Deed each Nominee
                    Director is entitled to communicate any information (and
                    provide copies of such information) received by that
                    director in relation to any member of MGM Grand Australia
                    Group to an Option Holder. To the extent that the Nominee
                    Director requires specific confirmation, consent, or
                    ratification for any such disclosure from his fellow
                    directors or in general meeting, then the parties shall do
                    all things in their lawful power to assist in or procure
                    such confirmation, consent or ratification.

          6.5  CONSULTANCY SERVICES OF MR OSBORNE

               Mr James Osborne shall at the request of MGM Grand Diamond
               provide consultancy services to MGM Grand Australia periodically,
               but in aggregate for a period of no more than four weeks during
               each calendar year, until the earlier of the Call Option Exercise
               Date or the expiry of the Call Option Period. The consultancy
               services shall be provided at no remuneration (except for
               reimbursement for travelling, hotel and associated expenses). The
               manner and timetable pursuant to which such consulatancy services
               are to be rendered shall be determined having regard to Mr
               Osborne's other activities. Mr Osborne shall be a signatory to
               this Deed solely to confirm his adherence to this Clause 6.5.

          6.6  RELATED PARTY TRANSACTIONS
               --------------------------

               (a)  Any contract, arrangement or transaction of whatsoever
                    nature between any member of the MGM Group or between any
                    Associate of the MGM Group and any member of MGM Grand
                    Australia Group ("Related Party Transaction") shall be
                    entered into on the basis:

                    (i)   the relevant member or members of MGM Grand Australia
                          Group pays consideration no higher than would be
                          reasonable, prudent and appropriate for such member of
                          MGM Grand Australia Group to pay to an independent
                          party providing a comparable service or benefit; and

                    (ii)  the relevant member or members of the MGM Grand
                          Australia Group received consideration no lower than
                          would be reasonable, prudent and appropriate for such
                          member to receive

                                      23

 
                          from an independent party receiving a comparable 
                          service or benefit.

               (b)  Any Related Party Transactions shall be approved by the
                    Relevant Board of MGM Grand Australia Group on the basis
                    that its terms are arms length, bona fide and reasonable,
                    with all board members being entitled to participate in such
                    determination. With respect to any Related Party Transaction
                    pursuant to which MGM Grand Australia Group would incur a
                    cost or grant a benefit to the MGM Group in excess of Two
                    hundred thousand dollars ($200,000) in respect of any one
                    transaction or if any independent series of transactions
                    exceeds Five hundred thousand dollars ($500,000) in any
                    twelve month period, if the Nominee Director disputes the
                    bona fide's or reasonableness of such Related Party
                    Transaction then the expert appointed under Clause 9.1 shall
                    determine whether or not the Related Party Transaction
                    satisfies the pre-conditions contained in this Clause 6.6.

          6.7  FINAL SHAREHOLDERS AGREEMENT
               ----------------------------

               (a)  On or as soon as practicable after the Call Option

                    Grand Australia shall execute a Final Shareholders'
                    Agreement ("Final Shareholders' Agreement") embodying all of
                    the provisions of this Deed which remain to be performed or
                    are capable of application and the covenants and condition
                    and ancillary provisions reasonable or desirable to give
                    full effect to the provisions contained in Schedule 4. MGM
                    Grand Diamond, MGM Grand Australia and the Option Holders
                    shall procure that any Subsidiary of MGM Grand Australia,
                    and any member of the MGM Group of whom any Equity
                    Securities in MGM Grand Australia or any Subsidiary have
                    been issued as permitted by this Deed, shall become a party
                    to such Final Shareholders' Agreement to the extent that it
                    is lawfully possible for such person to be a party to the
                    Final Shareholders' Agreement. The parties shall act in good
                    faith to conclude the Final Shareholders' Agreement within a
                    reasonable period which shall not exceed 3 months from the
                    date negotiations to prepare a Final Shareholders' Agreement
                    begin.

               (b)  As from the Call Option Completion and until the Final
                    Shareholders Agreement is executed by all of the then
                    existing parties to this Deed and such other members of the
                    MGM Group as may be necessary, the provisions contained in
                    Schedule 4 are intended and shall be construed to act as
                    covenants between all of the parties hereto to protect the
                    minority interest of the Option Holders and shall apply
                    notwithstanding anything to the contrary in the constituent
                    documents of any member of the MGM Grand Australia Group.

          6.8  EXERCISE OF VOTING AND OTHER RIGHTS
               -----------------------------------

               (a)  MGM Grand Diamond agrees to exercise its voting and other

                    MGM Grand Australia Group to procure, so far as it lawfully
                    can, that each member of MGM Grand Australia Group and its
                    directors give effect to the terms and conditions of this
                    Deed.

               (b)  The Option Holders agree as and from Call Option Completion

                    their voting and other rights attaching to their MGMGA
                    Shares to procure, so far as they lawfully can, that their
                    Nominee Directors give effect to the terms and conditions of
                    this Deed.

               (c)  If in the option of the Option Holders and the MGM Grand
                    Diamond, each acting reasonably, it is necessary or
                    desirable to amend the articles of association of MGM Grand
                    Australia or any Subsidiary in order to comply with

               MGM Grand Diamond recognises and acknowledges that one of the
               preferred exit mechanisms for the Option Holders would be the
               Listing of all the ordinary share capital of MGM Grand Australia.
               If the Option Holder shall issue a notice to MGM Grand Diamond
               that they wish MGM Grand Australia to obtain such a Listing
               within twelve months from the date of the notice, then (subject
               to any restriction imposed by law on MGM Grand Diamond, MGM Grand
               Australia or the MGM Grand Australia Group member holding the
               Casino Licence); MGM Grand Diamond shall give due consideration
               to such request, including without limitation, to the extent it
               deems it desirable to do so appoint an independent consultant of
               appropriate experience to advise on the merits of obtaining a
               Listing.

          7.2  COMMITMENT OF SHAREHOLDERS
               --------------------------

               Nothing in Clause 7 shall oblige MGM Grand Diamond to sell any of
               the MGMGA Shares held by it or to require MGM Grand Australia to
               issue any new MGMGA Shares. However, if MGM Grand Diamond and the
               Option Holders (assuming the Call Option has been exercised)
               agree to seek to obtain a Listing, then the Option Holders agree
               to all of their MGMGA Shares being quoted on the relevant Stock
               Exchange and to offer by way of sale all or such portions of
               their shareholding in MGM Grand Australia as MGM Grand Diamond
               may request, provided that MGM Grand Australia and/or MGM Grand
               Diamond sell in such offering the aggregate of not less than Ten
               percent (10%) of the issued MGMGA Shares prior to any such
               offering.

                                      25

 
          7.3  NO OBLIGATION TO LIST
               ---------------------

               (a)  For the avoidance of doubt neither MGM Grand Diamond nor the
                    Option Holders will be under any obligation to consent to a
                    Listing, such consent to be given or withheld in their sole
                    and absolute discretion, but the merits of such Listing
                    shall be considered in good faith once the request has been
                    made by the Option Holders upon MGM Grand Diamond pursuant
                    to Clause 7.1.

               (b)  Notwithstanding that a party has consented to a Listing such
                    consent may be withdrawn anytime prior to Listing, subject
                    to any third party contractual obligations, if any party so
                    elects as a result of an adverse movement in the proposed
                    issue price of a share on Listing or the imposition of
                    unreasonable conditions.

     8.   PUT OPTION
          ----------

          8.1  CONDITION PRECEDENT
               -------------------

               If by the first anniversary of the Call Option Exercise Date:-

               (a)  no Listing of the ordinary share capital of MGM Grand
                    Australia has occurred or is not considered desirable by the
                    Option Holders and MGM Grand Diamond; or

               (b)  if the Listing has been obtained but the Listing is on a
                    market which has insufficient liquidity based on bona fide
                    estimates, to absorb a sale of all of the Call Option Shares
                    then held by the Option Holders, within a period of six
                    months after such Listing; then the following provisions of
                    this Clause 8 will apply. Any dispute concerning the
                    aforegoing shall be resolved in accordance with Clause 9.1.

                    occurred prior to the commencement of the Put Option Period,
                    at any time after the occurrence of the Event of Default and
                    so long as such Event of Default is continuing, but in no
                    event after the expiration of the Put Option Period.

                                      26

 
               To the extent that the Put Option is not so exercised it shall

          8.5  NO WITHDRAWAL OF NOTICE
               -----------------------

               An Option Holder shall not be entitled to withdraw a notice 
               served pursuant to Clause 8.4, once it has been duly served.

          8.6  CONTRACT FOR SALE AND PURCHASE
               ------------------------------

               (a)  Upon receipt by MGM Grand Diamond of a notice from the
                    Option Holders, given in accordance with Clause 8.4, a
                    contract for the sale and purchase of the Put Option Shares

                    its nominee ("MGM Nominee") as purchaser and the Option
                    Holders as vendors shall be created as at the date of
                    receipt of that notice. If MGM Grand Diamond nominates a
                    person to be the MGM Nominee to acquire the Put Option
                    Shares under this Clause 8.6 (details of the nominee are
                    communicated to the Option Holders at least five Business
                    Days before the Put Option Completion), MGM Grand Diamond

                    surety for the payment of the Put Option Consideration.

               (b)  It shall be a condition to Completion of the sale and

                              Nominee) considers unacceptable, to the effect
                              that the acquisition of the Put Option Shares is
                              not objected to under the Foreign Acquisitions and
                              Takeovers Act 1976; or

               (b)  MGM Grand Diamond or MGM Nominee (as the case may be) may,
                    at its option, pending the curing of the breach of

     9.   DISPUTE RESOLUTION
          ------------------

          9.1  RESOLUTION BY AUDITOR
               ---------------------

               In the event that the Option Holders and MGM Grand Diamond are
               unable to agree in relation to the matter referred to in Clauses
               3.6(d), 3.10, 6.2(b)(i), 6.6, 8.1 or Schedules 2 or 3, then the
               auditors for the time being of MGM Grand Australia shall as
               experts and not as arbitrators make a determination in relation
               to the subject matter in dispute, which in the absence of
               manifest error shall be final binding. Any of the parties may
               make a submission to the auditor in relation to the subject
               matter of his proposed determination and the auditor shall be
               given access to such information as he reasonably requires to
               make a proper and full determination. The costs of the auditor
               shall be borne as to one half by MGM Grand Diamond and, as to the
               other half by the Option Holders. For the avoidance of doubt, MGM
               Grand Diamond and the Option Holders intend that no such
               resolution by MGM Grand Australia's auditor shall prevent such
               auditor from continuing in the capacity of MGM Grand Australia's
               independent auditor and in the event, in the opinion of such
               auditor, it may not resolve such dispute and continue in such
               capacity it shall designate an auditor of comparable standing to
               resolve such dispute.

          9.2  GENERAL DISPUTE RESOLUTION

                    competent jurisdiction, nor shall the taking of Proceedings
                    in one or more jurisdiction preclude the taking of
                    Proceedings in any other jurisdiction, whether concurrently
                    or not.

               (d)  Promptly after service of any process the party filing such
                    process shall dispatch a copy thereof to the other parties
                    by registered mail, postage prepaid, but failure of the

                    for service of process in Australia. Such agents shall in

                          (CALL OPTION CONSIDERATION)
                          ---------------------------

1.   The Call Option Consideration shall be an amount expressed in Australian 
     Dollars equal to the amount calculated in accordance with the following 
     formula:

                    C=0.225 x (SSC + SSC(P X I) - D -AFC)
                                         -----
                                           360
     where

     C    is the aggregate Call Option Consideration payable on exercise of the 
          Call Option;

     SSC  is $83,000,000, subject to the "Adjustments" as such term is defined
          in the third sentence of Clause 3.1 of the Casino Sale Agreement to
          reflect operations, certain balance sheet items, dividends and
          distributions specified therein;

     I    is the average of One per cent (1%) plus LIBOR as at the Casino Sale
          Completion and at the expiry of each 90 day period thereafter,
          expressed as a decimal and pro-rated for periods of less than 90 days;

     P    is the number of days from the Casino Sale Completion until the Call 
          Option Completion; and

     D    is the aggregate amount of all distributions (whether in cash or in
          specie), dividends (whether final, interim or bonus) and return of
          capital to the shareholders of MGM Grand Australia made or agreed to
          be made or paid or otherwise declared during the period referred to in
          P above (except to the extent of distributions made after the Call
          Option Exercise Date, to which Clause 5.2(e) of the Option Deed is
          applicable).

     AFC  is:

          (a)  the aggregate amount of all repayments or prepayments of
               principal under or pursuant to the Acquisition Financing;

          (b)  the aggregate amount of all interest payments made by MGM Grand 
               Australia under the Acquisition Financing;

          (c)  any other costs, expenses or payments made by MGM Grand Australia
               or any Subsidiary of MGM Grand Australia in relation to the
               Acquisition Financing or any Encumbrance granted in connection
               with the Acquisition Financing; and

                                      45

 
          (d)  the aggregate outstanding balance of the Acquisition Financing to
               the extent it is not discharged or assumed pursuant to Clause
               3.10(a):

          in respect of paragraphs (a)-(c) made on or before the Call Option
          Exercise Date, and in respect of paragraph (d) as at Call Option
          Exercise Date, and in each case after deducting the benefit to the
          MGM Grand Australia Group of any resulting Australian tax deduction,
          tax credit or other tax properly claimed or claimable in respect of
          such payment. However, if an amount that was claimable as at the date
          of Call Option Completion is later determined by MGM Grand Australia
          or the relevant tax authorities not to be properly claimable or to be
          disallowed then the Call Option Consideration shall be adjusted and
          the additional consideration shall be paid to the Option Holders
          within Five (5) Business Days of a determination referred to above.

2.   Where the calculation of the Call Option Consideration results in a
     positive number then the Call Option Consideration required to be paid by
     each of the Option Holders shall be its Agreed Proportion of the positive
     number. However, where the calculation of the Call Option Consideration
     results in a negative amount then MGM Grand Diamond shall pay an aggregate
     amount equal to that negative amount ("Rebate") to the Option Holders in
     the Agreed Proportions and no monetary payment will be required to be made
     by the Option Holders to MGM Grand Diamond in respect of the exercise of
     the Call Option.

3.   If there is a bona fide dispute as to the calculation of I or D then
     Completion of the Call Option shall nevertheless take place at the time and
     place provided in this instrument and the aggregate Call Option
     Consideration shall be Twenty two and one half per cent (22.5%) of SSC,
     which shall be adjusted upward or downward as the case may be by the
     payment or refund of monies within Five (5) Business Days of settlement of
     the dispute as to interpretation or I or D. Any dispute shall be referred
     to the expert appointed under Clause 9.1 to resolve.

                           (PUT OPTION CONSIDERATION)
                           --------------------------

          1.   The Put Option Consideration shall be the consideration payable
               to the Option Holders on the exercise of its Put Option. For each
               MGMGA Share held by an Option Holder such person shall be
               entitled to be paid an amount determined in accordance with the
               following formula:-


                                        (D X I)
                               FMV + FMV(-----)
                                        ( 360 )
                           PPS=----------------
                                      NS


               where

               PPS  is the price per MGMGA Share payable to an Option Holder on 
                    exercise of the Put Option.

               FMV  is the "Fair Market Value" of MGM Grand Australia as at the
                    Put Option Exercise Date determined in accordance with the
                    following provisions of this Schedule 3;

               NS   is the number of issued MGMGA Shares of MGM Grand Australia 
                    as at the Put Option Exercise Date;

               I    is the average of One per cent (1%) plus LIBOR (as at the
                    Put Option Exercise Date and at the expiry of each 90 day
                    period thereafter, expressed as a decimal and pro rated for
                    period of less than 90 days; and

               D    is the number of days from the relevant Put Option Exercise 
                    Date to relevant Put Option Completion.

          2.   Subject to paragraph 7, the Fair Market Value of MGM Grand
               Australia as at the Put Option Exercise Date shall be calculated
               by taking the numerical average of the valuations determined by
               two separate investment banks experienced in the valuation of
               companies in Australia, one to be appointed by the Option Holders
               and the other by MGM Grand Diamond ("Valuation Experts"). The
               Option Holders and MGM Grand Diamond any also agree in the place
               of one or more of the investment banks to use another suitable
               professional firm or organisation. In either case all costs of
               such valuations shall be for the account of the appointor.

          3.   Each Valuation Expert shall be provided with copies of all
               submissions and letters of instruction (which documents should
               fairly represent the brief given to the Valuation Expert) given
               to the other Valuation Expert. Copies shall also be given to the
               Option Holder or MGM Grand Diamond if they do not already possess
               such documents. Additionally, each Valuation Expert may request
               such other reasonable information to

                                      47

 
               assist it in making its determination and the parties shall
               procure as far as they are legally able that MGM Grand Australia
               Group provides the necessary information.

          4.   The Valuation Experts shall each be instructed to provide a
               single amount as the Fair Market Value of MGM Grand Australia as
               a complete entity without regard to minority shareholdings,
               special rights conferred under the Articles of Association or
               otherwise and any premium for control. If contrary to its
               instructions the Valuation Expert does not express a single
               amount as a Fair Market Value but express a range of values, then
               for the purposes of determining the average of the valuations of
               each Valuation Expert referred to in paragraph 2 of this Schedule
               3, the median of such range shall be used. The Option Holder and
               MGM Grand Diamond shall instruct their respective Valuation
               Experts within Ten (10) Business Days of the Put Option Exercise
               Date and instruct such Valuation Expert to provide a draft
               valuation report within Twenty (20) Business Days. A copy of the
               draft valuation report shall be served on the Option Holder and
               MGM Grand Diamond and each of those parties shall have the right,
               to be exercised within Ten (10) Business Days after receipt of
               the draft valuation report, to respond in writing only, to the
               Valuation Expert providing the draft valuation report with its
               comments and observations in relation to the draft valuation
               report. The Valuation Expert shall be further instructed to
               complete and finalise its draft valuation report no less than
               Fifteen (15) Business Days after it has served on the Option
               Holder and MGM Grand Diamond a copy of the draft valuation
               report.

          5.   If contrary to Clause 3.10(a) MGM Grand Diamond has not satisfied
               its obligations thereunder as at Put Option Exercise Date then
               the Fair Market Valuation of MGM Grand Australia shall be made on
               the basis that such obligations under Clause 3.10(a) were deemed
               to be satisfied as at Call Exercise Date.

          6.   Copies of the final valuation reports should be furnished to all
               parties and if there is a dispute as to average valuation this
               shall be resolved by the expert appointed pursuant to Clause 9.1.

          7.   If the Fair Market Values determined by each of the Valuation
               Experts differ by more than 10% then the Option Holders and MGM
               Grand Diamond shall appoint a new Valuation Expert to finally and
               conclusively determine the Fiar Market Value. The new Valuation
               Expert will be given copies of the parties prior submissions and
               be instructed to determine the Fair Market Value in accordance
               with this Schedule. If the Option Holders and MGM Grand Diamond
               are unable to agree on the identity of the new Valuation Expert
               then such Valuation Expert shall be nominated by the expert
               appointed pursuant to Clause 9.1 of the Deed.

          8.   The Option Holder and MGM Grand Diamond agree that any
               information received by them pursuant to the above provisions
               from one or other Valuation Expert shall be treated as
               confidential and used solely for the purpose of determining the
               Fair Market Value and shall not be given to any third party. The
               parties agree to co-operate with the reasonable requests of the 
               Valuation Experts.

          9.   Subject to paragraph 5 above, the parties may agree from time to
               time the basis on which the valuation of the Fair Market Value is
               to be determined by the Valuation

                                      48

 
               Expert. However, in the absence of agreement, prior to referral
               to the Valuation Experts, each Valuation Expert shall make its
               own determination of the proper basis for valuation.

                    Willing Vendor defaults in transferring the relevant Sale
                    Shares pursuant to Clause 10.2(b) the Offeror Member and the

                         the parties shall use their best endeavours to obtain

                         transfer to a bank account nominated by the Offeror
                         Member or Willing Vendors, as the case may be.

          10.4 If the option granted pursuant to Clause 10.2(b) is not exercised
               within the period provided therein in respect of all the Sale
               Shares, no exercise of any option under that Clause will be valid

          10.5 (a)  If the Remaining Shareholders fail or neglect to exercise
                    all of the options granted pursuant to Clause 10.2 within
                    the period provided therein, the Offeror Member and the
                    Willing Vendors may transfer all (but not some only) of the
                    Sale Shares to the Proposed Purchaser at any time within

                    (i)   the expiration of the period within which the option 
                          may be exercised pursuant to Clause 10.2(b); or

                          Shareholders that they do not intend to exercise that
                          option.

               (b)  The conditions precedent referred to in Clause 10.3(c) shall
                    apply equally to the Proposed Purchaser as to any other
                    proposed transferee and the Offeror Member and Willing
                    Vendors shall procure that the conditions precedent are
                    satisfied before the expiry of the three calendar month
                    period referred to in Clause 10.5(a). If the conditions
                    precedent are not so satisfied within the said three
                    calendar month period then no transfer of the Sale Shares to
                    the Proposed Purchaser shall occur unless all of the other
                    shareholders so consent.

               (b)  the Secretary shall, within Ten (10) Business Days of the
                    date of receipt of the Shareholder's notice, convene a

                    be considered and put to the vote by the Shareholders.

          11.2 If Shareholders, in aggregate representing more than seventy-five
               per cent (75%) per cent of the then issued MGMGA Shares, are
               willing to accept the Third Party Offer ("the Offerors"), then

                    purchase the Offerors' Equity Securities in MGM Grand
                    Australia in the proportion which each Offeree's Equity
                    securities in MGM Grand Australia bears to the total number
                    of issued Equity Securities in MGM Grand Australia, inter

               (b)  any Offeree willing to exercise its option must do so in
                    writing and deliver such notice to the Offerors prior to the
                    Ten (10) Business Days period referred to in paragraph (a);
                    and

               (c)  if the option is not exercised for the number of equities
                    equal to the Offerors' Equity Securities in MGM Grand

                    Equity Securities in MGM Grand Australia shall take place to
                    any accepting Offeree and the provisions of Clause 11.3
                    shall thereafter apply.

                                      58

 
          11.3 Where no sale of the Offerors' Equity Securities in MGM Grand
               Australia takes place in terms of Clause 11.2, then the Offerors
               shall be entitled to accept the Third Party's Offer to purchase
               all of the issued Equity Securities of MGM Grand Australia on
               behalf of all Shareholders and in order to give effect to the
               acceptance of the Third Party Offer, the Offereees hereby
               nominate and irrevocably appoint the Offerors as their attorney

               MGM Grand Australia (including the Offeree's Equity Securities)
               to the Third Party at the price and on terms and conditions which
               are no less favourable than those set out in the Third Party
               Offer. Without limiting the generality of the foregoing, the
               Offerees empower and authorise the Offerors to cause the
               necessary documentation to be prepared and to sign such
               documentation on behalf of the Offerees for the sale of all of
               the Equity Securities of MGM Grand Australia to the Third Party,
               to receive on their behalf their proportion of the net proceeds
               of sale and to ratify and confirm anything done by their

          11.4 No Shareholder shall accept any offer from a Third Party pursuant
               to Clause 11.1 unless it procures that the Third Party provides
               an unconditional, enforceable representation for the benefit of
               the Shareholders that such Third Party:

               (a)  is not an Associate of any of the Shareholders at the date
                    of the offer;

               (b)  neither it nor any of its Associates shall be or have the
                    option to become Associates of any of the Shareholders or
                    any of their Associates during the Twelve (12) months
                    following completion of the sale of the Equity Securities;
                    and

               (c)  neither before the date of the offer nor during the period

                    arrangement or understanding with any Shareholder or any
                    Associate of a Shareholder on terms which are not bona fide
                    arms length terms and which confer a direct or indirect
                    benefit on such Shareholder or its Associate attributable in
                    whole or part to the relevant entity being a holder or
                    former holder of Equity Securities of MGM Grand Australia.

          11.5 Any Shareholder described in Clauses 11.4(a) to (c) shall
               respectively indemnify and keep indemnified at all times after
               completion of the sale of the Equity Securities all other
               Shareholders for all loss, damages, and costs arising from the
               breach of the respective representations of the Third Party made
               or required to be made pursuant to Clause 11.4.

          PART 12 DIVIDENDS

               Subject to compliance with applicable law and third party
               contractual obligations to which the MGM Grand Australia Group
               may be subject, the Shareholders shall use their best endeavours
               to ensure that at least Fifty per cent 50% of the annual
               consolidated profits of MGM Grand Australia Group are distributed
               to the Shareholders by way of dividends. Without limiting the
               generality of the foregoing:-

                                      59


 
               (a)  all and every preliminary matter required by law, this
                    Schedule 4 or the Articles of Association of any member of
                    MGM Australia Group to be done by any Shareholder or any
                    member of the MGM Grand Australia Group to procure the
                    availability of such profits for declaration and
                    distribution by MGM Grand Australia shall be done;

               (b)  all dividends shall be paid as far as practicable as fully 
                    franked dividends;

               (c)  all final dividends shall be declared no later than 5 months
                    after the end of the relevant Financial Year and paid no
                    later than 6 months after the end of that Financial Year;
                    and

               (d)  where a third party contractual obligation has restricted
                    the amount of any dividends which maybe declared or paid in
                    any year, to an amount less than 50% of the annual
                    consolidated profits of MGM Grand Australia Group then as
                    soon as practicable after such contractual obligation ceases
                    to apply the Shareholders shall seek to ensure that MGM
                    Grand Australia shall declare and pay such level of
                    dividends as it is legally permitted to do to recoup such
                    shortfall in an expeditious manner. For the purposes of this
                    Clause the shortfall is the amount that would otherwise have
                    been paid pursuant to this Clause if the contractual
                    obligation had not existed. It is acknowledged that to
                    recoup such dividends expeditiously the level of dividends
                    may exceed 50% of annual consolidated profits of the MGM
                    Grand Australia Group in any one accounting period until the
                    average payment of dividends for the period from the date
                    this Schedule becomes effective until the date such
                    obligation ceases to apply is equal to or in excess of 50%
                    of the cumulative annual consolidated profits of the MGM
                    Grand Australia Group.

          PART 13 AGREEMENT TO PREVAIL

          13.1 The parties acknowledge that this Deed creates rights and
               obligations which are in addition to the rights and obligations
               created or to be created in the Articles of Association of MGM
               Grand Australia and the parties hereto hereby confirm that such
               rights and obligations are to be exercised and observed
               concurrently and not in substitution one for another. The parties
               agree that to the extent any conflict between any of those
               respective rights and obligations arises at any time, the rights
               and obligations created by this Deed (including this Schedule 4)
               shall be exercised or observed to the exclusion of any right or
               obligation created by the Articles of Association of any member
               of the MGM Grand Australia Group so far as it permitted by law
               and is necessary to resolve the conflict.

          13.2 Each Shareholder agrees that it will vote and act at all times as
               a member of MGM Grand Australia and will procure that to the
