fail to notify the Administrative Agent in writing of their consent to the
extension), Borrower and the Co-Borrowers may cause all of the Non-Consenting
Banks to be removed as Banks under this Agreement pursuant to Section 11.27,
provided that such removal shall be accomplished by assignment to one or more
--------
Eligible Assignees which are willing to consent to the request for extension and
not by reduction of the amount of Commitment.  In the event that

                                      -31-

sufficient Eligible Assignees can be identified to assume the Pro Rata Shares of
the Non-Consenting Banks, then the request for extension shall be granted with
the effect as set forth above.

          2.11  Administrative Agent's Right to Assume Funds Available for
                ----------------------------------------------------------
Advances.  Unless the Administrative Agent shall have been notified by any Bank
--------
no later than 10:00 a.m. on the Banking Day of the proposed funding by the
Administrative Agent of any Loan that such Bank does not intend to make
available to the Administrative Agent such Bank's portion of the total amount of
such Loan, the Administrative Agent may assume that such Bank has made such
amount available to the Administrative Agent on the date of the Loan and the
Administrative Agent may, in reliance upon such assumption, make available to
Borrower or the relevant Co-Borrower a corresponding amount.  If the
Administrative Agent has made funds available to Borrower or a Co-Borrower based
on such assumption and such corresponding amount is not in fact made available
to the Administrative Agent by such Bank, the Administrative Agent shall be
entitled to recover such corresponding amount on demand from such Bank.  If such
Bank does not pay such corresponding amount forthwith upon the Administrative
Agent's demand therefor, the Administrative Agent promptly shall notify Borrower
or that Co-Borrower who shall pay such corresponding amount to the
Administrative Agent.  The Administrative Agent also shall be entitled to
recover from such Bank interest on such corresponding amount in respect of each
day from the date such corresponding amount was made available by the
Administrative Agent to Borrower or the Co-Borrowers to the date such
corresponding amount is recovered by the Administrative Agent, at a rate per
annum equal to the daily Federal Funds Rate.  Nothing herein shall be deemed to
relieve any Bank from its obligation to fulfill its share of the Commitment or
to prejudice any rights which the Administrative Agent, Borrower or any Co-
Borrower may have against any Bank as a result of any default by such Bank
hereunder.

          2.12  Release and Reattachment of Collateral.  (a)  Each of the Banks
                --------------------------------------
hereby consents to the release on the Closing Date of the Liens granted by the
Collateral Documents described in the Old Loan Agreement.  The Administrative
Agent is hereby authorized and directed by each of the Banks to execute and
deliver to Borrower and its Subsidiaries all such termination statements,
mortgage releases, terminations of deeds of trust, terminations of Liens, and
other instruments, documents and agreements as may be necessary or desirable, or
which Borrower may reasonably request, to accomplish the purposes of this
Section or evidence the effects hereof.

          (b)  If a Collateral Event occurs and if either (x) the MGM Senior
Notes or the Mirage Senior Notes then require the granting of Liens in any
assets of Borrower or any of its Restricted Subsidiaries or (y) any such MGM
Senior Notes or Mirage Senior Notes are in fact granted any Liens by Borrower,
the Co-Borrowers or any of the Restricted Subsidiaries, then Borrower and the
Co-Borrowers shall, and shall cause each of the Restricted Subsidiaries to,
promptly and in any event within thirty days following the occurrence of such
Collateral Event and in any event not later than the granting of any Liens in
such collateral any MGM Senior Notes, the Mirage Senior Notes or any trustee
therefor, grant perfected Liens in the same collateral to secure the Obligations
(including any Related Swap Agreements) equally, ratably and on a pari passu
basis, provided that Borrower and the Restricted Subsidiaries shall not be
       --------
obligated to provide Liens in any Property to the extent that Gaming Laws
prohibit the granting of Liens in such Property to the Administrative Agent and
the MGM Senior Notes unless and until all required approvals of Gaming Boards
thereto are obtained.  In such event, Borrower shall, and shall cause each
Restricted Subsidiary to, use its best efforts to obtain all necessary

                                      -32-
<PAGE>

consents from the applicable Gaming Boards to grant a perfected Lien on such
Property securing the Obligations and, upon receipt of all consents needed to
grant such a perfected Lien, shall promptly take all action (or cause the
Restricted Subsidiaries to take all action) reasonably necessary in order to
grant and perfect such a Lien. The Liens granted pursuant to this clause (b)
shall be (i) equal, ratable and pari passu with any Liens securing the MGM
Senior Notes, (ii) granted concurrently with the granting of any Liens in favor
of the MGM Senior Notes or the Mirage Senior Notes (whichever first occurs), and
(iii) granted pursuant to instruments, documents and agreements which are
reasonably acceptable to the Administrative Agent and no less favorable to the
Administrative Agent and the other Creditors than those granted to the MGM
Senior Notes or the Mirage Senior Notes (whichever is most favorable to the
holders thereof). While each of the Liens contemplated by this clause (b) shall
be equal, ratable and pari passu in the manner described above, it is
                      ---- -----
acknowledged that the same may subordinate to certain prior Liens in favor of
creditors other than the holders of the MGM Senior Notes and the Mirage Senior
Notes permitted pursuant to Section 6.7. In connection with the granting of any
such Liens, Borrower and its Restricted Subsidiaries shall provide to the
Administrative Agent (y) policies of title insurance on customary terms and
conditions, to the extent that policies of title insurance on the corresponding
Property are provided to the holders of the MGM Senior Notes (and in an insured
amount that bears the same proportion to the principal amount of the Commitment
as the insured amount in the policies provided to the holders of the MGM Senior
Notes bears to the aggregate amount of the MGM Senior Notes), and (z) legal
opinions and other assurances as the Administrative Agent may reasonably
request.

          (c)  If, following any Collateral Event, Borrower and its Restricted
Subsidiaries are then entitled to the release of all of the equal, ratable and
pari passu Liens described in clause (b) above securing the MGM Senior Notes and
---- -----
the Mirage Senior Notes, and provided that no Default or Event of Default has
                             --------
then occurred and remains continuing, Borrower and the Co-Borrowers may in their
sole discretion request that the Administrative Agent release any Liens securing
the Obligations in accordance with this clause (c).  Borrower and the Co-
Borrowers shall submit any request under this Section in the form of a
Certificate, in form and substance acceptable to the Administrative Agent,
signed by a Senior Officer of Borrower and each Co-Borrower certifying that no
Default or Event of Default exists, together with a written consent to the
release of collateral executed by each Guarantor and such other supporting
information as the Administrative Agent may request, including evidence
reasonably satisfactory to the Administrative Agent that the Mirage Senior
Notes, the MGM Senior Notes and the creditors under the Other Loan Agreements
shall previously or concurrently release all Liens held by such creditors.
Promptly upon receipt of such a Certificate, the Administrative Agent shall
provide a copy thereof to the Banks and, unless the Requisite Banks contest the
accuracy thereof within five Banking Days, shall (i) execute and deliver to
Borrower and its Subsidiaries reconveyances and releases of such Liens, and (ii)
return to the Persons legally entitled thereto, all collateral pledged in
support of the Obligations, all at the sole expense of Borrower and the Co-
Borrowers (a "Collateral Release"), in each case subject to the requirement that
the Liens held by the Mirage Senior Notes, the MGM Senior Notes and the
creditors under the Other Loan Agreements are previously or concurrently
released.  No Collateral Release shall constitute or be construed as a release
(or to require the release) of the Guaranty.

                    (b)  Interest accrued on each Base Rate Loan on the first
     Banking Day of each Fiscal Quarter shall be due and payable on that day.
     Except as otherwise provided in Section 3.9, the unpaid principal amount of
     ------
     any Base Rate Loan shall bear interest at a fluctuating rate per annum
     equal to the Base Rate plus the applicable Base Rate Margin. Each change in
                            ----
     the interest rate under this Section 3.1(b) due to a change in the Base
     Rate shall take effect simultaneously with the corresponding change in the
     Base Rate.

                    (c)  Interest accrued on each Eurodollar Rate Loan which is
     for a term of three months or less shall be due and payable on the last day
     of the related Eurodollar Period. Interest accrued on each other Eurodollar
     Rate Loan shall be due and payable on the date which is three months after
     the date such Eurodollar Rate Loan was made (and, in the event that all of
     the Banks have approved a Eurodollar Period of longer than six months,
     every three months thereafter through the last day of the Eurodollar
     Period) and on the last day of the related Eurodollar Period. Except as

     otherwise provided in Section 3.9, the unpaid principal amount of any
     Eurodollar Rate Loan shall bear interest at a rate per annum equal to the
     Eurodollar Rate for that Eurodollar Rate Loan plus the applicable

               --------------------
underwriting fees in the amount heretofore agreed upon by letter agreement

that Bank by the Lead Arranger, provided forth in a letter agreement with Bank

period (unless the Closing Date occurs or has earlier occurred),

Banks pro rata according to their Pro Rata Share, a facility fee equal to one
half of the Facility Fee Rate in effect from time to time __________ the

any partial reduction or termination of the Commitment pursuant to Sections 2.8,
2.9 or 11.27.

          3.5  [Reserved].

               -----------
Borrower and the Co-Borrowers shall pay to the Administrative Agent an agency
fee in such amounts as heretofore agreed upon by letter agreement between
Borrower and Bank of America and the Lead Arranger.  The agency fee is for the
services to be performed by the Administrative Agent in acting as Administrative
Agent and is fully earned on the date paid.  The agency fee paid to the
Administrative Agent is solely for its own account and is nonrefundable.

          3.7  Increased Commitment Costs.  If any Bank shall determine in good
               --------------------------
faith that the introduction after the Closing Date of any applicable law, rule,
regulation or guideline regarding capital adequacy, or any change therein or any
change in the interpretation or administration thereof by any central bank or
other Governmental Agency charged with the interpretation or administration
thereof, or compliance by such Bank (or its Eurodollar Lending Office) or any
corporation controlling the Bank, with any request, guideline or directive
regarding capital adequacy (whether or not having the force of Law) of any such
central bank or other authority, affects or would affect the amount of capital
required or expected to be maintained by such Bank or any corporation
controlling such Bank and (taking into consideration such Bank's or such
corporation's policies with respect to capital adequacy and such Bank's desired
return on capital) determines in good faith that the amount of such capital is
increased, or the rate of return on capital is reduced, as a consequence of its
obligations under this Agreement, then, within ten Banking Days after demand of
such Bank, Borrower and the Co-Borrowers shall pay to such Bank, from time to
time as specified in good faith by such Bank, additional amounts sufficient to
compensate such Bank in light of such circumstances, to the extent reasonably
allocable to such obligations under this Agreement, provided that Borrower and
                                                    --------
the Co-Borrowers shall not be obligated to pay any such amount which arose prior
to the date which is ninety days preceding the date of such demand or is
attributable to periods prior to the date which is ninety days preceding the
date of such demand.  Each Bank's determination of such amounts shall be
conclusive in the absence of manifest error.  Any request for compensation by a
Bank under this Section shall set forth the basis upon which it has been
determined that such an amount is due from Borrower and the Co-Borrowers, a
calculation of the amount due, and a certification that the corresponding costs
or diminished rate of return on capital have been incurred or sustained by the
Bank.  If Borrower and the Co-Borrowers become obligated to pay a material
amount under this Section to any Bank, that Bank will be subject to removal in
accordance with Section 11.27; provided that Borrower and the Co-Borrowers shall
                               --------
have paid such amount to that Bank and that Borrower and the Co-Borrowers,
within the thirty day period following the date of such payment, shall have
notified that Bank in writing of their intent to so remove the Bank.

                    (a)  In the event that any Governmental Agency imposes on
     any Bank any reserve or comparable requirement (including any emergency,
                                                     ---------
     supplemental or other reserve)

                                      -37-
<PAGE>

     with respect to the Eurodollar Obligations of that Bank, Borrower or the
     relevant Co-Borrower shall pay that Bank within five Banking Days after
     demand all amounts necessary to compensate such Bank (determined as though
     such Bank's Eurodollar Lending Office had funded 100% of its Eurodollar
     Rate Advance in the Designated Eurodollar Market) in respect of the
     imposition of such reserve requirements. The Bank's determination of such
     amount shall be conclusive in the absence of manifest error.

               (b)  If, after the date hereof, the existence or occurrence of
     any Special Eurodollar Circumstance:

               (1)  shall subject any Bank or its Eurodollar Lending Office to
          any tax, duty or other charge or cost with respect to any Eurodollar
          Rate Advance, any of its Notes evidencing Eurodollar Rate Advances or
          its obligation to make Eurodollar Rate Advances, or shall change the
          basis of taxation of payments to any Bank attributable to the
          principal of or interest on any Eurodollar Rate Advance or any other
          amounts due under this Agreement in respect of any Eurodollar Rate
          Advance, any of its Notes evidencing Eurodollar Rate Advances or its
          obligation to make Eurodollar Rate Advances, excluding (i) taxes
                                                       ---------
          imposed on or measured in whole or in part by its overall net income,
          gross income or gross receipts, (ii) franchise taxes imposed by (A)
          any jurisdiction (or political subdivision thereof) in which it is
          organized or maintains its principal office or Eurodollar Lending
          Office or (B) any jurisdiction (or political subdivision thereof) in
          which it is "doing business," and (iii) any withholding taxes or other
          taxes based on gross income imposed by the United States of America
          for any period with respect to which it has failed to provide Borrower
          with the appropriate form or forms required by Section 11.21, to the
          extent such forms are then available under applicable Laws;

               (2)  shall impose, modify or deem applicable any reserve not
          applicable or deemed applicable on the date hereof (including any
                                                              ---------
          reserve imposed by the Board of Governors of the Federal Reserve
          System, special deposit, capital or similar requirements against
          assets of, deposits with or for the account of, or credit extended by,
          any Bank or its Eurodollar Lending Office); or

               (3)  shall impose on any Bank or its Eurodollar Lending Office or
          the Designated Eurodollar Market any other condition affecting any
          Eurodollar Rate Advance, any of its Notes evidencing Eurodollar Rate
          Advances, its obligation to make Eurodollar Rate Advances or this
          Agreement, or shall otherwise affect any of the same;

     and the result of any of the foregoing, as determined in good faith by such
     Bank, increases the cost to such Bank or its Eurodollar Lending Office of
     making or maintaining any Eurodollar Rate Advance or in respect of any
     Eurodollar Rate Advance, any of its Notes evidencing Eurodollar Rate
     Advances or its obligation to make Eurodollar Rate Advances or reduces the
     amount of any sum received or receivable by such Bank or its Eurodollar
     Lending Office with respect to any Eurodollar Rate Advance, any of its
     Notes evidencing Eurodollar Rate Advances or its obligation to make
     Eurodollar Rate Advances (assuming such Bank's Eurodollar Lending

                                      -38-

     Office had funded 100% of its Eurodollar Rate Advance in the Designated
     Eurodollar Market), then, within five Banking Days after demand by such
     Bank (with a copy to the Administrative

     amounts as will compensate such Bank for such increased cost or reduction
     (determined as though such Bank's Eurodollar Lending Office had funded 100%
     of its Eurodollar Rate

     tion under this subsection and setting forth in reasonable detail the
     additional amount or amounts to be paid to it hereunder shall be conclusive
     in the absence of manifest error.

          If, after the date hereof, the existence or occurrence of any Special
     Eurodollar Circumstance shall, in the good faith opinion of any Bank, make
     it unlawful or

     of any Eurodollar Rate Advance or materially restrict the authority of such
     Bank to purchase or sell, or to take deposits of, Dollars in the Designated
     Eurodollar Market, or to determine or

     istrative Agent, then such Bank's obligation to make Eurodollar Rate
     Advances shall be suspended for the duration of such illegality or
     impossibility and the Administrative Agent

     notice, the outstanding principal amount of such Bank's Eurodollar Rate
     Advances, together with accrued interest thereon, automatically shall be
     converted to Base Rate Advances on either

     Bank may lawfully continue to maintain and fund such Eurodollar Rate
     Advances to such day(s) or (2) immediately if such Bank may not lawfully
     continue to fund and maintain such provided that in such event the

     knowledge, occurring after the Closing Date, which will cause that Bank to
     notify the Administrative Agent

     nation will avoid the need for such notice and will not, in the good faith
     judgment of such Bank, otherwise be materially disadvantageous to such
     Bank. In the event that any Bank is unable,

     Loan or Advance, such Bank shall fund such amount as a Base Rate Advance
     for the same period of time, and such amount shall be treated in all
     respects as a Base Rate Advance. Any

     Section shall promptly notify the Administrative Agent and Borrower of the
     cessation of the Special Eurodollar Circumstance which gave rise to such
     suspension.

                    If, with respect to any proposed Eurodollar Rate Loan:

               (1)  circumstances affecting the Designated Eurodollar Market
          generally that are beyond the reasonable control of the Banks,
          deposits in Dollars (in the applicable amounts) are not

          Eurodollar Period; or

                                      -39-
<PAGE>

               (2)  the Requisite Banks advise the Administrative Agent that the
          Eurodollar Rate as determined by the Administrative Agent (i) does not
          represent the effective pricing to such Banks for deposits in Dollars
          in the Designated Eurodollar Market in the relevant amount for the
          applicable Eurodollar Period, or (ii) will not adequately and fairly
          reflect the cost to such Banks of making the applicable Eurodollar
          Rate Advances;

     then the Administrative Agent forthwith shall give notice thereof to
     Borrower and the Banks, whereupon until the Administrative Agent notifies
     Borrower that the circumstances giving rise to such suspension no longer
     exist, the obligation of the Banks to make any future Eurodollar Rate
     Advances shall be suspended unless (but only if clause (2) above is the
                                 ------
     basis for such suspension) Borrower and each Co-Borrower notify the
     Administrative Agent in writing that they elect to pay the Enhanced
     Eurodollar Margin with respect to all Eurodollar Rate Loans made during
     such period.

               (e)  Upon payment or prepayment of any Eurodollar Rate Advance
     (other than as the result of a conversion required under clause (c) of this
      ----- ----
     Section) on a day other than the last day in the applicable Eurodollar
     Period (whether voluntarily, involuntarily, by reason of acceleration, or
     otherwise), or upon the failure of Borrower or any Co-Borrower (for a
     reason other than the failure of a Bank to make an Advance) to borrow on
     the date or in the amount specified for a Eurodollar Rate Advance in any
     Request for Loan, or upon the failure of Borrower or any Co-Borrower to
     prepay a Eurodollar Rate Loan or Advance on the date specified in a notice
     of prepayment delivered to the Administrative Agent pursuant to Section
     3.1(e), Borrower and the Co-Borrowers shall pay to the appropriate Bank
     within ten Banking Days after demand a prepayment fee, failure to borrow
     fee or failure to prepay fee, as the case may be (determined as though 100%
     of that Bank's Eurodollar Rate Advance had been funded in the Designated
     Eurodollar Market), equal to the sum of:
                                      --- --

               (1)  the principal amount of the Eurodollar Rate Advance prepaid
          or not borrowed or prepaid, as the case may be, times [the number of
                                                          -----
          days from and including the date of prepayment or failure to borrow or
          prepay, as applicable, to but excluding the last day in the applicable
          Eurodollar Period], divided by 360, times the applicable Interest
                              ----------      -----
          Differential (provided that the product of the foregoing formula must
                        --------
          be a positive number); plus
                                 ----

               (2)  all out-of-pocket expenses incurred by the Bank reasonably
          attributable to such payment, prepayment or failure to borrow.

     Each Bank's determination of the amount of any prepayment fee, failure to
     borrow fee or failure to prepay fee payable under this Section shall be
     conclusive in the absence of manifest error.

               (f)  Each Bank agrees to endeavor promptly to notify Borrower of
     any event of which it has actual knowledge, occurring after the Closing
     Date, which will entitle such Bank to compensation pursuant to clause (a)
     or clause (b) of this Section, and agrees to designate a different
     Eurodollar Lending Office if such designation will avoid the need for or

                                      -40-
<PAGE>

     reduce the amount of such compensation and will not, in the good faith
     judgment of such Bank, otherwise be materially disadvantageous to such
     Bank. Any request for compensation by a Bank under this Section shall set
     forth the basis upon which it has been determined that such an amount is
     due from Borrower and the Co-Borrowers, a calculation of the amount due,
     and a certification that the corresponding costs have been incurred by the
     Bank.

               (g)  If any Bank claims compensation or is excused from making or
     continuing Eurodollar Rate Loans or Advances under this Section:

                         (i)   Borrower and the Co-Borrowers may at any time,
          upon at least four Eurodollar Banking Days' prior notice to the
          Administrative Agent and such Bank and upon payment in full of the
          amounts provided for in this Section through the date of such payment
          plus any prepayment fee (subject to clause (c) of this Section)
          ----
          required by clause (e) of this Section, pay in full the affected
          Eurodollar Rate Advances of such Bank or request that such Eurodollar
          Rate Advances be converted to Base Rate Advances; and

                         (ii)  In the case where Borrower and the Co-Borrowers
          become obligated to pay a material amount under this Section to any
          Bank, that Bank will be subject to removal in accordance with Section
          11.27; provided that Borrower and the Co-Borrowers shall have paid
                 --------
          such amount to that Bank and that Borrower and the Co-Borrowers,
          within the thirty day period following the date of such payment, shall
          have notified that Bank in writing of their intent to so remove the
          Bank.

          3.9   Late Payments.  If any installment of principal or interest or
                -------------
any fee or cost or other amount payable under any Loan Document to the
Administrative Agent or any Bank is not paid when due, it shall thereafter bear
interest at a fluctuating interest rate per annum at all times equal to the rate
otherwise payable with respect thereto plus 2% per annum (or, in the case of any
                                       ----
Obligations which do not bear stated interest, at the rate then otherwise
applicable to Base Rate Loans plus 2% per annum), to the fullest extent
                              ----
permitted by applicable Laws.  Accrued and unpaid interest on past due amounts
(including interest on past due interest) shall be compounded monthly, on the
 ---------
last day of each calendar month, to the fullest extent permitted by applicable
Laws.

          3.10  Computation of Interest and Fees.  Computation of interest on
                --------------------------------
Base Rate Loans shall be calculated on the basis of a year of 365 or 366 days,
as the case may be, and the actual number of days elapsed; computation of
interest on Eurodollar Rate Loans and all fees under this Agreement shall be
calculated on the basis of a year of 360 days and the actual number of days
elapsed.  Borrower and the Co-Borrowers acknowledge that such latter calculation
method will result in a higher yield to the Banks than a method based on a year
of 365 or 366 days.  Interest shall accrue on each Loan for the day on which the
Loan is made; interest shall not accrue on a Loan, or any portion thereof, for
the day on which the Loan or such portion is paid.  Any Loan that is repaid on
the same day on which it is made shall bear interest for one day.
Notwithstanding anything in this Agreement to the contrary, interest in excess
of the maximum amount permitted by applicable Laws shall not accrue or be
payable hereunder or under the Notes, and any amount paid as interest hereunder
or under the Notes which would

                                      -41-
<PAGE>

otherwise be in excess of such maximum permitted amount shall instead be treated
as a payment of principal.

          3.11  Non-Banking Days.  If any payment to be made by Borrower or any
                ----------------
other Party under any Loan Document shall come due on a day other than a Banking
Day, payment shall instead be considered due on the next succeeding Banking Day
and the extension of time shall be reflected in computing interest and fees.

          3.12  Manner and Treatment of Payments.
                --------------------------------

                    (a)  Each payment hereunder (except payments pursuant to
                                                 ------
     Sections 3.7, 3.8, 11.3, 11.11 and 11.22) or on the Notes or under any
     other Loan Document shall be made to the Administrative Agent, at the
     Administrative Agent's Office, for the account of each of the Banks or the
     Administrative Agent, as the case may be, in immediately available funds
     not later than 12:00 noon, California local time, on the day of payment
     (which must be a Banking Day). All payments received after such time, on
     any Banking Day, shall be deemed received on the next succeeding Banking
     Day. The amount of all payments received by the Administrative Agent for
     the account of each Bank shall be immediately paid by the Administrative
     Agent to the applicable Bank in immediately available funds and, if such
     payment was received by the Administrative Agent by 12:00 noon, California
     local time, on a Banking Day and not so made available to the account of a
     Bank on that Banking Day, the Administrative Agent shall reimburse that
     Bank for the cost to such Bank of funding the amount of such payment at the
     Federal Funds Rate. All payments shall be made in lawful money of the
     United States of America.

                    (b)  Each payment or prepayment on account of any Loan shall
     be applied pro rata according to the outstanding Advances made by each Bank
     comprising such Loan.

                    (c)  Each Bank shall use its best efforts to keep a record
     (which may be intangible or electronic or other intangible form) of
     Advances made by it and payments received by it with respect to each of its
     Notes and, subject to Section 10.6(g), such record shall, as against
     Borrower and the Co-Borrowers, be presumptive evidence of the amounts
     owing. Notwithstanding the foregoing sentence, the failure by any Bank to
     keep such a record shall not affect Borrower's and the Co-Borrowers' joint
     and several obligations to pay the Obligations.

                    (d)  Each payment of any amount payable by Borrower or any
     other Party under this Agreement or any other Loan Document shall be made
     free and clear of, and without reduction by reason of, any taxes,
     assessments or other charges imposed by any Governmental Agency, central
     bank or comparable authority, excluding (i) taxes imposed on or measured in
                                   ---------
     whole or in part by overall net income, gross income or gross receipts,
     (ii) franchise taxes imposed on any Bank by (A) any jurisdiction (or
     political subdivision thereof) in which it is organized or maintains its
     principal office or Eurodollar Lending Office or (B) any jurisdiction (or
     political subdivision thereof) in which it is "doing business", (iii) any
     withholding taxes or other taxes based on gross income imposed by the
     United States of America that are not attributable to any change in any Law
     or the interpretation or administration of any Law by any

                                      -42-
<PAGE>

     Governmental Agency and (iv) any withholding tax or other taxes based on
     gross income imposed by the United States of America for any period with
     respect to which it has failed to such forms are then available under
     applicable Laws (all such non-excluded taxes, assessments or other charges
     being hereinafter referred to as "Taxes"). To the extent that Borrower or
     any Taxes from any amount payable to any Bank under this Agreement, they
     shall (i) make such deduction or withholding and pay the same to the
     relevant Governmental Agency and (ii) pay after-Tax amount equal to the
     amount to which that Bank would have been entitled under this Agreement
     absent such deduction or withholding. If and when receipt of such payment
     results refund such excess to Borrower or the relevant Party. If Borrower
     or any such Party becomes obligated to pay a material amount under this
     Section to any Bank, that Bank will be subject to provided that Borrower or
                                                       --------
     the relevant Party shall day period following the date of such payment,
     shall have notified that Bank in writing of their intent to so remove the
     Bank.

             Funding Sources. Nothing in this Agreement shall be deemed to
             ---------------
     obligate any representation by any Bank that it has obtained or will obtain
     the funds for any Loan or Advance in any particular place or manner,
     __________ that each Bank which is not a bank under the laws of the United
     States or any state thereof severally represents and warrants that it has
     obtained the funds for its "prohibited transactions" as such term is
     defined in ERISA.

          3.14 __________________________.  Any decision by the Administrative
Agent or any Bank not to require payment of any interest (_______ interest at
the Default Rate), fee, cost or other amount payable under any Loan Document, or
to calculate any amount payable by a

Agent's or such Bank's right to require full payment of any interest (including
                                                                      ---------

Banks, which successor Administrative Agent shall be approved by Borrower (and
such approval shall not be unreasonably withheld or delayed), provided that, to

collateral for which a lienholder must be qualified under such Gaming Laws until
the new Administrative Agent can be so qualified (but the incumbent
Administrative Agent shall be entitled to the indemnities and other protections
provided to the Administrative Agent hereunder in such capacity).  If no
successor Administrative Agent is appointed prior to the effective date of the
resignation of the Administrative Agent, the Administrative Agent may appoint,
after consulting with the Banks and the Borrower, a successor Administrative
Agent from among the Banks.  Upon the acceptance of its appointment as successor
Administrative Agent hereunder, such successor Administrative Agent shall
succeed to all the rights, powers and duties of the retiring Administrative
Agent and the term "Administrative Agent" shall mean such successor
Administrative Agent and the retiring Administrative Agent's appointment, powers
and duties as Administrative Agent shall be terminated.  After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Article 10, and Sections 11.3, 11.11 and 11.22, shall inure
to its benefit as to any

time, if any, as the Requisite Banks appoint a successor Administrative Agent as
provided for above.

          Foreclosure on Collateral.  In the event of foreclosure or enforcement
          -------------------------
of the Lien created by any of the Loan Documents, title to any collateral
encumbered thereby shall be taken and held by the Administrative Agent (or an
Affiliate or designee thereof) pro rata for the benefit of the Banks in
accordance with the Obligations outstanding to each of them and shall be
administered in accordance with the standard form of collateral holding
participation agreement used by the Administrative Agent in comparable
syndicated credit facilities.

        10.10  Intercreditor Arrangements; Attornment Agreements.  Provided
               -------------------------------------------------
that no Default or Event of Default has then occurred, the Administrative Agent
is hereby irrevocably authorized by the other Creditors to enter into (a)
intercreditor arrangements acceptable to the Administrative Agent with creditors
(or a trustee or other representative for such creditors) holding the Mirage
Senior Notes, the MGM Senior Notes and the Other Loan Agreements to effectuate
the provisions of Section 6.7 requiring any Liens of the Administrative Agent to
be equal, ratable and pari passu with the creditors holding the Mirage Senior
                      ----------
Notes, the MGM Senior Notes and the Other Loan Agreements, provided that any
such arrangements shall require the concurrent release of the Liens held by such
creditors if a Collateral Release occurs, and (b) attornment, non-disturbance
and estoppel agreements acceptable to the Administrative Agent with lessees of
interests in leases of real property from Borrower and its Restricted
Subsidiaries permitted hereby, provided in each case that not less than 5
                               --------

Administrative Agent shall circulate drafts thereof to the Banks, and the
Requisite Banks shall not have objected to the form thereof.

          10.11  No Obligations of Borrower and the Co-Borrowers.  Nothing
                 -----------------------------------------------
contained in this Article 10 shall be deemed to impose upon Borrower or any Co-
Borrower any obligation in respect of the due and punctual performance by the
Administrative Agent of its obligations to the Banks under any provision of this
Agreement, and Borrower and the Co-Borrowers shall have no liability to the
Administrative Agent or any of the Banks in respect of any failure by the
Administrative Agent or any Bank to perform any of its obligations to the
Creditors under this Agreement.  Without limiting the generality of the
foregoing, where any provision of this Agreement relating to the payment of any
amounts due and owing under the Loan Documents provides that such payments shall
be made by Borrower or the Co-Borrower to the Administrative Agent for the
account of the Banks, Borrower's and the Co-Borrowers' obligations to the Banks
in respect of such payments shall be deemed to be satisfied upon the making of
such payments to the Administrative Agent in the manner provided by this

other Banks of their obligations to make initial Advances.  A default by any
Bank will not increase the Pro Rata Share of

           --------------------------

               (a) This Agreement and the other Loan Documents to which Borrower
     and the Co-Borrowers are a Party will be binding upon and inure to the
     exclusive benefit of Borrower, the Co-Borrowers, the Creditors, and their
     respective successors and assigns, except that Borrower and the Co-
                                        ------
     Borrowers may not assign their respective rights hereunder or thereunder or
     any interest herein or therein without the prior written consent of all the
     Banks.  Each Bank represents that it is not acquiring its Notes with a view
     to the distribution thereof within the meaning of the Securities Act of
     1933, as amended (subject to any requirement that disposition of its Notes
     must be within the control of such Bank).  Any Bank may at any time pledge
     its Notes or any other instrument evidencing its rights as a Bank under
     this Agreement to a Federal Reserve Bank, but no such pledge shall release
     that Bank from its obligations hereunder or grant to such Federal Reserve
     Bank the rights of a Bank hereunder absent foreclosure of such pledge.

               (b) From time to time, each Bank may assign to one or more
     Eligible Assignees all or any portion of its Pro Rata Share, provided that
                                                                  --------
     (i) such Eligible Assignee, if not then a Bank or an Affiliate of the
     assigning Bank, shall be approved by each of the Administrative Agent and
     (if no Event of Default then exists) Borrower and the Co-Borrowers (none of
     which approvals shall be unreasonably withheld or delayed), (ii) such
     assignment shall be evidenced by an Assignment Agreement, a copy of which
     shall be furnished to the Administrative Agent as hereinbelow provided,
     (iii) except in the case of an assignment to an Affiliate of the assigning
           ------
     Bank, to another Bank or of the entire remaining Commitment of the
     assigning Bank, the assignment shall not assign a Pro Rata Share that is
     less than $5,000,000, (iv) the effective date of any such assignment shall
     be as specified in the Assignment Agreement, but not earlier than the date
     which is five Banking Days after the date the

                                      -78-
<PAGE>

     Administrative Agent has received the Assignment Agreement, (v) such
     assignment shall be of a constant and non-varying percentage of the Pro
     Rata Share of the assigning Bank, and (vi) the assignor Bank shall have
     paid a $3500 assignment fee to the Administrative Agent. Upon the effective
     date of such Assignment Agreement, the Eligible Assignee named therein
     shall be a Bank for all purposes of this Agreement, with the Pro Rata Share
     set forth therein and, to the extent of such Pro Rata Share, the assigning
     Bank shall be released from its further obligations under this Agreement.
     Borrower and the Co-Borrowers agree that they shall execute and deliver
     (against delivery by the assigning Bank to Borrower of its Note) to such
     assignee Bank, a Note evidencing that assignee Bank's Pro Rata Share, and
     to the assigning Bank, a Note evidencing the remaining balance Pro Rata
     Share retained by the assigning Bank.

               (c) By executing and delivering a Assignment Agreement, the
     Eligible Assignee thereunder acknowledges and agrees that: (i) other than
     the representation and warranty that it is the legal and beneficial owner
     of the Pro Rata Share being assigned thereby free and clear of any adverse
     claim, the assigning Bank has made no representation or warranty and
     assumes no responsibility with respect to any statements, warranties or
     representations made in or in connection with this Agreement or the
     execution, legality, validity, enforceability, genuineness or sufficiency
     of this Agreement or any other Loan Document; (ii) the assigning Bank has
     made no representation or warranty and assumes no responsibility with
     respect to the financial condition of Borrower or its Subsidiaries or the
     performance by Borrower and its Subsidiaries of the Obligations; (iii) it
     has received a copy of this Agreement, together with copies of the most
     recent financial statements delivered pursuant to Section 7.1 and such
     other documents and information as it has deemed appropriate to make its
     own credit analysis and decision to enter into such Assignment Agreement;
     (iv) it will, independently and without reliance upon the Administrative
     Agent or any Bank and based on such documents and information as it shall
     deem appropriate at the time, continue to make its own credit decisions in
     taking or not taking action under this Agreement; (v) it appoints and
     authorizes the Administrative Agent to take such action and to exercise
     such powers under this Agreement as are delegated to the Administrative
     Agent by this Agreement; and (vi) it will perform in accordance with their
     terms all of the obligations which by the terms of this Agreement are
     required to be performed by it as a Bank.

          (d) The Administrative Agent shall maintain at the Administrative
     Agent's Office a copy of each Assignment Agreement delivered to it and a
     register (the "Register") of the names and address of each of the Banks and
     the Pro Rata Share held by each Bank, giving effect to each Assignment
     Agreement. The Register shall be available during normal business hours for
     inspection by Borrower, the Co-Borrowers or any Bank upon reasonable prior
     notice to the Administrative Agent. Borrower, the Co-Borrowers and the
     Creditors shall deem and treat the Persons listed as Banks in the Register
     as the holders and owners of the Pro Rata Share listed therein for all
     purposes hereof, and no assignment or transfer of any such Pro Rata Share
     shall be effective, in each case unless and until a Assignment Agreement
     effecting the assignment or transfer thereof shall have been accepted by
     the Administrative Agent and recorded in the Register as provided above.
     Prior to such recordation, all amounts owed with respect to the applicable
     Pro Rata Share shall be owed to the Bank listed in the Register as the
     owner thereof, and any request, authority or consent of any Person who, at
     the time of making

                                      -79-
<PAGE>

     such request or giving such authority or consent, is listed in the Register
     as a Bank shall be conclusive and binding on any subsequent holder,
     assignee or transferee of the corresponding Pro Rata Share.

          (e) Each Bank may from time to time grant participations to one or
     more banks or other financial institutions (including another Bank) in a
                                                 ---------
     portion of its Pro Rata Share; provided, however, that (i) such Bank's
                                    --------  -------
     obligations under this Agreement shall remain unchanged, (ii) such Bank
     shall remain solely responsible to the other parties hereto for the
     performance of such obligations, (iii) the participating banks or other
     financial institutions shall not be a Bank hereunder for any purpose
     except, if the participation agreement so provides, for the purposes of
     ------
     Sections 3.7, 3.8, 11.11 and 11.22 but only to the extent that the cost of
     such benefits to Borrower and the Co-Borrowers does not exceed the cost
     which Borrower and the Co-Borrowers would have incurred in respect of such
     Bank absent the participation, (iv) Borrower, the Co-Borrowers, the
     Administrative Agent and the other Banks shall continue to deal solely and
     directly with such Bank in connection with such Bank's rights and
     obligations under this Agreement, (v) the participation interest shall be
     expressed as a percentage of the granting Bank's Pro Rata Share as it then
     exists and shall not restrict an increase in the Commitment, or in the
     granting Bank's Pro Rata Share, so long as the amount of the participation
     interest is not affected thereby, and (vi) the consent of the holder of
     such participation interest shall not be required for amendments or waivers
     of provisions of the Loan Documents other than those which (A) extend the
     Maturity Date or any other date upon which any payment of money is due to
     the Banks, (B) reduce the rate of interest on the Notes, any fee or any
     other monetary amount payable to the Banks, (C) reduce the amount of any
     installment of principal due under the Notes, (D) release the Guaranty, or

     any Gaming Board, to the extent required by applicable Gaming Laws, and to
     compliance with applicable securities laws, if any.

          (g) Notwithstanding anything to the contrary contained herein, any
     Bank (a "Granting Bank") may grant to one or more SPC's established or
     maintained by that Granting Bank the option to provide all or any part of
     any Loan or Advance that such Granting Bank would otherwise be obligated to
     make pursuant to Sections 2.1, 2.2 or 2.3, provided that (i) nothing herein
     shall constitute a commitment to make any Loan by any SPC, (ii) if a SPC
     elects not to exercise such option or otherwise fails to provide all or any
     part of such Loan, the Granting Bank shall be obligated to make such Loan
     pursuant to the terms hereof, and (iii) the rights of any such SPC shall be
     derivative of the rights of the Granting Bank, and each SPC shall be
     subject to all of the restrictions upon the Granting Bank herein contained.
     Each SPC shall be conclusively presumed to have made arrangements with its
     Granting Bank for the exercise of voting and other rights hereunder in a
     manner which is acceptable to the SPC, and the Administrative Agent, the
     other Creditors, Borrower, the Co-Borrowers and each other Party shall be
     entitled to rely upon and deal solely with the Granting Bank with respect
     to Loans and Advances made by or through its SPC. The making of a Loan by a
     SPC hereunder

     as if, such Loan were made by the Granting Bank. Each party hereto hereby
     agrees that no SPC shall be liable

     shall remain with the related Granting Bank).  In furtherance of the
     foregoing, each party hereto hereby agrees (which agreement shall survive
     the termination of this Agreement) that, prior to

     indebtedness of any SPC, it will not institute against, or join any other
     person in instituting against, such SPC any bankruptcy, reorganization,
     arrangement, insolvency or liquidation

     provided _____ the Granting Bank for each SPC hereby agrees to indemnify,
     --------
     save, and hold harmless each other party hereto for any loss, cost, damage
     and expense arising out of their inability to institute any such proceeding
     against its SPC. In addition, notwithstanding anything to the contrary
     contained in this Section 11.8, any SPC may (i) with notice to, but without
     the prior written consent of, the Borrower, the Co-Borrowers or the
     Administrative Agent and without paying any processing fee therefor, assign
     all or a portion of its interests in any Loans to its Granting Bank or to
     any financial institutions providing liquidity and/or credit facilities to
     or for the account of such SPC to fund the Loans made by such SPC or to
     support the securities (if any) issued by such SPC to fund such Loans (but
     nothing contained herein shall be construed in derogation of the obligation
     of the Granting Bank to make Loans hereunder), provided that neither the
                                                    -------- ----
     consent of the SPC or of any such assignee shall be required for amendments
     or waivers of provisions of the Loan Documents except for those amendments
     or waivers for which the consent of participants is required under Section
     11.8(e)(vi), and (ii) disclose on a confidential basis (in the same manner
     described in Section 11.14) any non-public information relating to its
     Loans to any rating agency, commercial paper dealer or provider of a
     surety, guarantee or credit or liquidity enhancement to such SPC.

          11.9  Right of Setoff.  If an Event of Default has occurred and is
                ---------------
continuing, the Administrative Agent or any Bank (but in each case only with the
consent of the Requisite Banks) may exercise its rights under Article 9 of the
Uniform Commercial Code and other applicable Laws and, to the extent permitted
by applicable Laws, apply any funds in any deposit account maintained with it by
Borrower, the Co-Borrowers and/or any of their Property in its possession
against the Obligations.

          11.10  Sharing of Setoffs.  Each Bank severally agrees that if it,

against Borrower, any Co-Borrower, or otherwise, receives payment of the
Obligations held by it that is ratably more than any other Bank, through any
means, receives in payment of the Obligations held by that Bank, then, subject
to applicable Laws: (a) the Bank exercising the right of setoff, banker's lien
or counterclaim or otherwise receiving such payment shall purchase, and shall be
deemed to have simultaneously purchased, from the other Bank a participation in
the Obligations held by the other Bank and shall pay to the other Bank a
purchase price in an amount so that the share of the Obligations held by each
Bank after the exercise of the right of setoff, banker's lien or counterclaim or
receipt of payment shall be in the same proportion that existed prior to the
exercise of the right of setoff, banker's lien or counterclaim or receipt of
payment; and (b) such other adjustments and purchases of participations shall be
made from time to time as shall be equitable to ensure that all of the Banks
share any payment obtained in respect of the Obligations ratably in accordance
with each Bank's share of the Obligations immediately prior to, and without

taking into account, the payment; ______ that, if all or any portion of a
disproportionate payment obtained as a result of the exercise of the right of
setoff, banker's lien, counterclaim or otherwise is

of a participation shall be rescinded and the purchase price thereof shall be
restored to the extent of the recovery, but without

and after the purchase have the right to give all notices, requests, demands,
directions and other communications under this Agreement with respect to the
portion of the Obligations purchased to the

rower and each Co-Borrower expressly consents to the foregoing arrangements and
agrees that any Bank holding a participation in an Obligation so purchased may
exercise any and all rights of setoff,

owner of the Obligation purchased.

Agreement and those of any other Loan Document, the provisions of this Agreement
shall control and govern; provided that the inclusion of supplemental rights or
                          --------
remedies in favor of the Creditors in any other Loan Document shall not be
deemed a conflict with this Agreement. Each Loan Document was drafted with the
joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof.

          11.17  Governing Law.  Except to the extent otherwise provided

that is held to be inoperative, unenforceable or invalid as to any party or in
any jurisdiction shall, as to that party or jurisdiction, be inoperative,
unenforceable or invalid without affecting the remaining provisions or the
operation, enforceability or validity of that provision as to any other party or
in any other jurisdiction, and to this end the provisions of all Loan Documents
are declared to be severable.

          11.19  Headings.  Article and Section headings in this Agreement and
                 --------
the other Loan Documents are included for convenience of reference only and are

Documents.

          11.21  Foreign Banks and Participants.  Each Bank that is incorporated
                 ------------------------------

after the Closing Date (or after accepting an assignment or receiving a
participation interest herein pursuant to Section 11.8, if applicable) two duly
completed copies, signed by a Responsible Official, of either Form 1001
(relating to such Bank and entitling it to a complete exemption from withholding
on all payments to be made to such Bank by Borrower and the Co-Borrowers
pursuant to this Agreement) or Form 4224 (relating to all payments to be made to
such Bank by Borrower and the Co-Borrowers pursuant to this Agreement) of the
United States Internal Revenue Service or such other evidence (including, if

a copy to the Administrative Agent), such additional duly completed and signed
copies of one of such forms (or such successor forms as shall be adopted from

such evidence as is satisfactory to Borrower, the Co-Borrowers and the
Administrative Agent of any available exemption from, United States withholding
taxes in respect of all payments to be made to such Bank by Borrower and the Co-
Borrowers pursuant to this Agreement and (b) take such steps as shall not be
materially disadvantageous to it, in the reasonable judgment of such Bank, and
as may be reasonably necessary (including the re-designation of its Eurodollar
Lending Office, if any) to avoid any requirement of applicable Laws

that Borrower and the Co-Borrowers make any deduction or withholding for taxes

or the Administrative Agent become aware that a participation has been granted
pursuant to Section 11.8(e) to a financial institution that is incorporated or
otherwise organized under the Laws of a jurisdiction other than the United
States of America, any State thereof or the District of Columbia, then, upon
request made by Borrower, the Co-Borrowers or the Administrative Agent to the
Bank which granted such participation, such Bank shall cause such participant
financial institution to deliver the same documents and information to Borrower,
the Co-Borrowers and the Administrative Agent as would be required under this
Section if such financial institution were a Bank.

proceedings and orders, judgments, remedial action requirements, enforcement
actions of any kind, and all costs and expenses incurred in connection therewith
(including reasonable attorneys' fees and the reasonably allocated costs of
 ---------
attorneys employed by the Administrative Agent or any Bank, and expenses to the
extent that the defense of any such action has not been assumed by Borrower and
the Co-Borrowers), arising directly or indirectly out of (i) the presence on,

contamination of any Property or natural resources arising in connection with
the generation, use, handling, storage, transport or disposal of any such
Hazardous Materials, and irrespective of whether any of such activities were or
will be undertaken in accordance with applicable Laws, but the foregoing
indemnity shall not apply to Hazardous Materials on any Real Property, the
presence of which is caused by the Creditors.  Borrower and each Co-Borrower
hereby acknowledges and agrees that, notwithstanding any other provision of this
Agreement or any of the other Loan Documents to the contrary, the obligations of
Borrower and the Co-Borrowers under this Section (and under Sections 4.18 and
5.9) shall be unlimited corporate obligations of Borrower and the Co-Borrowers
and shall not be secured by any deed of trust or mortgage on any Real Property.
          ---
Any obligation or liability of Borrower and the Co-Borrowers to any Indemnitee
under this Section shall survive the expiration or termination of this
Agreement, the repayment of all Loans and the payment and performance of all
other Obligations owed to the Banks.
