     referred to in the second sentence of Section 2.1(b), if applicable) has
     been made within the requisite notice periods set forth in Section 2.2 or
     2.3 prior to the end of the Eurodollar Period for any Eurodollar Rate Loan,
     then on the last day of such Eurodollar Period, such Eurodollar Rate Loan
     shall be automatically converted into a Base Rate Loan in the same amount.

               (h) If a Loan is to be made on the same date that another Loan is
     due and payable:

                    (i)  the Banks shall make available to the Administrative
          Agent (or the Administrative Agent shall make available to the Banks)
          the net amount of funds giving effect to both such Loans and the
          effect for purposes of this Agreement shall be the same as if separate
          transfers of funds had been made with respect to each such Loan; and

                    (ii)  in the case where the same Party is the primary
          borrower of both such Loans, Borrower or the relevant Co-Borrower
          shall make available to the Administrative Agent (or the
          Administrative Agent shall make available to such Party) the net
          amount of funds giving effect to both such Loans and the effect for
          purposes of this Agreement shall be the same as if separate transfers
          of funds had been made with respect to each such Loan.

          2.2  Base Rate Loans.  Each request by Borrower or any Co-Borrower
               ---------------

if applicable) received by the Administrative Agent, at the Administrative
Agent's Office, not later than 9:15 a.m. California local time, on the date
(which must be a Banking Day) of the requested Base Rate Loan.  All Committed

          2.3  Eurodollar Rate Loans.
               ---------------------

               (a)  Each request by Borrower or any Co-Borrower for a Eurodollar

     the absence of manifest error) and promptly shall give notice of the same

     telecopier (and if by telephone, promptly confirmed by telecopier).

          2.4  Letters of Credit.
               -----------------

               (a)  Subject to the terms and conditions hereof, at any time and
     from time to time from the Closing Date through the Banking Day immediately
     prior to the Maturity Date, the Issuing Bank shall issue such Letters of
     Credit under the Commitment as Borrower or any Co-Borrower may request by a
     Request for Letter of Credit; provided that (i) giving effect to all such
                                   --------
     Letters of Credit, the Outstanding Obligations do not exceed the then
     applicable Commitment, (ii) the Aggregate Effective Amount under all
     outstanding Letters of Credit shall not exceed $150,000,000, and (iii) each
     Letter of Credit issued for the account of a Co-Borrower shall be directly
     used to support the development, construction or operation of hotel/casino
     properties owned by that Co-Borrower.   As of the Closing Date, each of the
     Existing Letters of Credit shall be deemed to be issued and outstanding
     hereunder as a Letter of Credit, and each of the Banks shall be deemed to
     have purchased a ratable participation therein in accordance with the terms
     of this Section.  Each Letter of Credit shall be in a form reasonably
     acceptable to the Issuing Bank.  Unless all the Banks otherwise consent in
     a writing delivered to the Administrative Agent, no Letter of Credit shall
     have a term which exceeds one year or extends beyond the Maturity Date.

               (b)  Each Request for Letter of Credit shall be submitted to the
     Issuing Bank, with a copy to the Administrative Agent, at least five
     Banking Days prior to the date upon which the related Letter of Credit is
     proposed to be issued.  The Administrative Agent shall promptly notify the
     Issuing Bank whether such Request for Letter of Credit, and the issuance of
     a Letter of Credit pursuant thereto, conforms to the requirements of this
     Agreement.  Upon issuance of a Letter of Credit, the Issuing Bank shall
     promptly notify the Administrative Agent, and the Administrative Agent
     shall promptly notify the Banks, of the amount and terms thereof.

               (c)  Upon the issuance of a Letter of Credit, each Bank shall be
     deemed to have purchased at par a pro rata participation in such Letter of
     Credit from the Issuing Bank in an amount equal to that Bank's Pro Rata
     Share.  Without limiting the scope and nature of each Bank's participation
     in any Letter of Credit, to the extent that the Issuing Bank has not been
     reimbursed by Borrower or the relevant Co-Borrower for any payment required
     to be made by

                                      -32-
<PAGE>

     the Issuing Bank under any Letter of Credit, each Bank shall, pro rata
     according to its Pro Rata Share, pay the purchase price for such
     participation to the Issuing Bank through the Administrative Agent promptly
     upon demand therefor. The obligation of each Bank to so pay the
     participation purchase price to the Issuing Bank shall be absolute and
     unconditional and shall not be affected by the occurrence of an Event of
     Default or any other occurrence or event. Any such payment of the purchase
     price shall not relieve or otherwise impair the obligation of Borrower or
     the relevant Co-Borrower to reimburse the Issuing Bank for the amount of
     any payment made by the Issuing Bank under any Letter of Credit together
     with interest as hereinafter provided.

               (d)  Borrower and each Co-Borrower jointly and severally agree to
     pay to the Issuing Bank through the Administrative Agent an amount equal to
     any payment made by the Issuing Bank with respect to each Letter of Credit
     within one Banking Day after written demand made by the Issuing Bank
     therefor, together with interest on such amount from the date of any
     payment made by the Issuing Bank at the rate applicable to Base Rate Loans
     for three Banking Days and thereafter at the Default Rate, provided that,
                                                                --------
     anything to the contrary herein notwithstanding, the liability of Detroit
     shall be limited to those Letters of Credit which are used, directly or
     indirectly, to finance the design, development, construction or operation
     of the Detroit Project or which are actually issued to or for the account
     of Detroit.  The principal amount of any such payment shall be used to
     reimburse the Issuing Bank for the payment made by it under the Letter of
     Credit and, to the extent that the Banks have not reimbursed the Issuing
     Bank pursuant to Section 2.4(c), the interest amount of any such payment
     shall be for the account of the Issuing Bank.  Each Bank that has paid the
     participation purchase price to the Issuing Bank pursuant to Section 2.4(c)
     shall thereupon acquire a pro rata participation, to the extent of such
     payment, in the claim of the Issuing Bank against Borrower and the Co-
     Borrowers for reimbursement of principal and interest under this Section
     2.4(d) and shall share, in accordance with that pro rata participation, in
     any principal payment made by Borrower or the relevant Co-Borrowers with
     respect to such claim and in any interest payment made by Borrower or the
     relevant Co-Borrowers (but only with respect to periods subsequent to the
     date such Bank paid the participation purchase price to the Issuing Bank)
     with respect to such claim.

               (e)  Borrower or the relevant Co-Borrower may, pursuant to a
     Request for Loan, request that Committed Advances be made pursuant to
     Section 2.1(a) to provide funds for the payment required by Section 2.4(d)
     and, for this purpose, the conditions precedent set forth in Article 8
     shall not apply.  The proceeds of such Advances shall be paid directly to
     the Issuing Bank to reimburse it for the payment made by it under the
     Letter of Credit.

               (f)  If Borrower or the relevant Co-Borrower fails to make the
     payment required by Section 2.4(d) on a timely basis then, in lieu of the
     payment of the participation purchase price to the Issuing Bank under
     Section 2.4(c), the Issuing Bank may (but is not required to), without
     notice to or the consent of Borrower or any Co-Borrower, instruct the
     Administrative Agent to cause Committed Advances to be made by the Banks
     under their Pro Rata Shares of the Commitment in an aggregate amount equal
     to the amount paid by the Issuing Bank with respect to that Letter of
     Credit and, for this purpose, the conditions precedent set

                                      -33-
<PAGE>

     forth in Article 8 shall not apply. The proceeds of such Advances shall be
     paid directly to the Issuing Bank to reimburse it for the payment made by
     it under the Letter of Credit.

               (g)  The issuance of any supplement, modification, amendment,
     renewal, or extension to or of any Letter of Credit shall be treated in all
     respects the same as the issuance of a new Letter of Credit, except that
     the Issuing Bank's issuance fees shall be payable as set forth in the
     letter agreement referred to in Section 3.5.

               (h)  The obligation of Borrower and each Co-Borrower to pay to
     the Issuing Bank the amount of any payment made by the Issuing Bank under
     any Letter of Credit shall be absolute, unconditional, and irrevocable,
     subject only to performance by the Issuing Bank of its obligations to
     Borrower and each Co-Borrower under Uniform Commercial Code Section 5109.
     Without limiting the foregoing, the obligations of Borrower and each Co-
     Borrower to the Issuing Bank shall not be affected by any of the following
     circumstances:

                    (i)    any lack of validity or enforceability of the Letter
          of Credit, this Agreement, or any other agreement or instrument
          relating thereto;

                    (ii)    any amendment or waiver of or any consent to
          departure from the Letter of Credit, this Agreement, or any other
          agreement or instrument relating thereto, with the consent of Borrower
          and the Co-Borrowers;

                    (iii)    the existence of any claim, setoff, defense, or
          other rights which Borrower or any Co-Borrower may have at any time
          against the Issuing Bank, the Administrative Agent or any Bank, any
          beneficiary of the Letter of Credit (or any persons or entities for
          whom any such beneficiary may be acting) or any other Person, whether
          in connection with the Letter of Credit, this Agreement, or any other
          agreement or instrument relating thereto, or any unrelated
          transactions;

                    (iv)    any demand, statement, or any other document
          presented under the Letter of Credit proving to be forged, fraudulent,
          invalid, or insufficient in any respect or any statement therein being
          untrue or inaccurate in any respect whatsoever so long as any such
          document appeared to comply with the terms of the Letter of Credit;

                    (v)    payment by the Issuing Bank in good faith under the
          Letter of Credit against presentation of a draft or any accompanying
          document which does not strictly comply with the terms of the Letter
          of Credit;

          condition, packing, value or delivery of any Property purported to be
          represented by documents presented in connection with any Letter of
          Credit or any difference between any such Property and the character,
          quality, quantity, condition, or value of such Property as described
          in such documents;

          shipments or deliveries of Property as described in documents
          presented in connection with any Letter of Credit or the existence,
          nature and extent of any insurance relative thereto;

                    (viii)  the solvency or financial responsibility of any
          party issuing any documents in connection with a Letter of Credit;

                    (ix)    any failure or delay in notice of shipments or
          arrival of any Property;

                    (x)     any error in the transmission of any message
          relating to a Letter of Credit not caused by the Issuing Bank, or any
          delay or interruption in any such message;

                    (xi)    any error, neglect or default of any correspondent
          of the Issuing Bank in connection with a Letter of Credit (but without

          correspondent);

                    (xii)   any consequence arising from acts of God, war,
          insurrection, civil unrest, disturbances, labor disputes, emergency
          conditions or other causes beyond the control of the Issuing Bank;

                    (xiii)  so long as the Issuing Bank in good faith determines
          that the contract or document appears to comply with the terms of the
          Letter of Credit, the form, accuracy, genuineness or legal effect of
          any contract or document referred to in any document submitted to the

                    (xiv)   where the Issuing Bank has acted in good faith and
          observed general banking usage, any other circumstances whatsoever.

accorded to the Administrative Agent pursuant to Article 10, mutatis mutandis.

               (j)  The Uniform Customs and Practice for Documentary Credits, as

     2.5  Competitive Advances.
          --------------------

          (a)  Subject to the terms and conditions hereof, at any time and from
time to time from the Closing Date through and including the Maturity Date, each
Bank may in its sole and absolute discretion make Competitive Advances to
Borrower or to any Co-Borrower pursuant to Competitive Bids accepted by Borrower
or the

                                      -35-
<PAGE>

relevant Co-Borrower in such principal amounts as Borrower or the relevant Co-
Borrower may request pursuant to a Competitive Bid Request that do not result in
the aggregate outstanding principal Indebtedness evidenced by the Competitive
Advance Notes being in excess of the Maximum Competitive Outstandings Amount,
provided that after giving effect to the making of each Competitive Advance, the
--------
Outstanding Obligations shall not exceed the Commitment. Each Competitive
Advance made to a Co-Borrower shall be directly used to finance the development,
construction or operation of hotel/casino properties owned by that Co-Borrower.
No Competitive Advance made by any Bank shall relieve that Bank of its Pro Rata
Share of the undrawn Commitment.

          (b)  Borrower or the relevant Co-Borrower shall request Competitive
Advances by submitting Competitive Bid Requests to the Administrative Agent,
which specify the relevant date, amount and maturity of the proposed Competitive
Advance and whether the Competitive Bid requested is an Absolute Rate Bid or a
Eurodollar Margin Bid, or both.  Borrower and each Co-Borrower may submit
telephonic requests for Competitive Advances.  Any Competitive Bid Request made
by telephone shall promptly be confirmed by the delivery to Administrative Agent
in person or by telecopier of a written Competitive Bid Request.  The
Administrative Agent shall incur no liability whatsoever hereunder in acting
upon any telephonic Competitive Bid Request purportedly made by a Responsible
Official of Borrower, which hereby agrees to indemnify the Administrative Agent
from any loss, cost, expense or liability as a result of so acting.  The
Competitive Bid Request must be received by the Administrative Agent not later
than 9:00 a.m., California local time, on a Banking Day that is at least one
Banking Day prior to the date of the proposed Competitive Advance if an Absolute
Rate Bid is requested; if a Eurodollar Margin Bid is requested, it must be
received by the Administrative Agent five Banking Days prior to the date of the
proposed Competitive Advance.

          (c)  Unless the Administrative Agent otherwise agrees, in its sole and
absolute discretion, no Competitive Bid Request may be submitted within the five
Banking Day period following submission of another Competitive Bid Request.

          (d)  Each Competitive Bid Request must be made for a Competitive
Advance of at least $10,000,000 and shall be in an integral multiple of
$1,000,000.

          (e)  No Competitive Bid Request shall be made for a Competitive
Advance with a maturity of less than 14 days or more than 180 days, or with a
maturity date subsequent to the Maturity Date.

          (f)  The Administrative Agent shall, promptly after receipt of a
Competitive Bid Request, notify the Banks thereof by telephone and provide the
Banks a copy thereof by telecopier.  Any Bank may, by written notice to the
Administrative Agent (with a copy to Borrower and the Co-Borrowers), advise the
Administrative Agent that it elects not to be so notified of Competitive Bid
Requests, in which case the Administrative Agent shall not notify such Bank of
the Competitive Bid Request.

          (g)  Each Bank receiving a Competitive Bid Request may, in its sole
and absolute discretion, make or not make a Competitive Bid responsive to the
Competitive Bid Request.  Each Competitive Bid shall be submitted to the
Administrative Agent not later than 7:30 a.m. (or, in the case of the Bank which
is also the Administrative Agent, not later than 7:15 a.m.) California local
time, in the case of a Eurodollar Margin Bid, on the date which is four Banking
Days prior to the requested

                                      -36-
<PAGE>

Competitive Advance and, in the case of an Absolute Rate Bid, on the date of the
requested Competitive Advance. Any Competitive Bid received by the
Administrative Agent after 7:30 a.m. (or 7:15 a.m. in the case of the Bank which
is also the Administrative Agent) on such date shall be disregarded for purposes
of this Agreement. Any Competitive Bid made by telephone shall promptly be
confirmed by the delivery to the Administrative Agent in person or by telecopier
of a written Competitive Bid. The Administrative Agent shall incur no liability
whatsoever hereunder in acting upon any telephonic Competitive Bid purportedly
made by a Responsible Official of a Bank, each of which hereby agrees to
indemnify the Administrative Agent from any loss, cost, expense or liability as
a result of so acting with respect to that Bank.

          (h)  Each Competitive Bid shall specify the fixed interest rate or the
margin over the Eurodollar Rate, as applicable, for the offered Maximum
Competitive Advance set forth in the Competitive Bid.  The Maximum Competitive
Advance offered by a Bank in a Competitive Bid may be less than the Competitive
Advance requested by Borrower or the relevant Co-Borrower in the Competitive Bid
Request, but, if so, shall be an integral multiple of $1,000,000.  Any
Competitive Bid which offers an interest rate other than a fixed interest rate
                                              ----- ----
or a margin over the Eurodollar Rate, is in a form other than set forth in
Exhibit E or which otherwise contains any term, condition or provision not
contained in the Competitive Bid Request shall be disregarded for purposes of
this Agreement.  A Competitive Bid once submitted to the Administrative Agent
shall be irrevocable until 8:30 a.m. California local time, in the case of a
Eurodollar Margin Bid, on the date which is three Banking Days prior to the
requested Competitive Advance and, in the case of an Absolute Rate Bid, on the
date of the proposed Competitive Advance set forth in the related Competitive
Bid Request, and shall expire by its terms at such time unless accepted by
Borrower or the relevant Co-Borrower prior thereto.

          (i)  Promptly after 7:30 a.m. California local time, in the case of a
Eurodollar Margin Bid, on the date which is four Banking Days prior to the date
of the proposed Competitive Advance and, in the case of an Absolute Rate Bid, on
the date of the proposed Competitive Advance, the Administrative Agent shall
notify Borrower or the relevant Co-Borrower of the names of the Banks providing
Competitive Bids to the Administrative Agent at or before 7:30 a.m. on that date
(or 7:15 a.m. in the case of the Bank which is also the Administrative Agent)
and the Maximum Competitive Advance and fixed interest rate or margin over the
Eurodollar  Rate set forth by each such Bank in its Competitive Bid.  The
Administrative Agent shall promptly confirm such notification in writing
delivered in person or by telecopier to Borrower or the relevant Co-Borrower.

          (j)  Borrower or the relevant Co-Borrower may, in its sole and
absolute discretion, reject any or all of the Competitive Bids. If Borrower or
the relevant Co-Borrower accepts any Competitive Bid, the following shall apply:
(a) Borrower or the relevant Co-Borrower must accept all Absolute Rate Bids at
all lower fixed interest rates before accepting any portion of an Absolute Rate
Bid at a higher fixed interest rate, (b) Borrower or the relevant Co-Borrower
must accept all Eurodollar Margin Bids at all lower margins over the Eurodollar
Rate before accepting any portion of a Eurodollar Margin Bid at a higher margin
over the Eurodollar Rate, (c) if two or more Banks have submitted a Competitive
Bid at the same fixed interest rate or margin, then Borrower or the relevant Co-
Borrower must accept either all of such Competitive Bids or accept such
Competitive Bids in the same proportion as the Maximum Competitive Advance of
each Bank bears to the aggregate Maximum Competitive Advances of all such Banks,
and (d) Borrower and the Co-Borrower may not accept Competitive Bids for an
aggregate amount in excess of the requested Competitive Advance set forth in the
Competitive

                                      -37-
<PAGE>

Bid Request. Borrower or the relevant Co-Borrower must accept (i) each
Eurodollar Margin Rate Bid prior to 8:30 a.m. on the date which is three Banking
Days prior to the requested Competitive Advance and (iii) each Absolute Rate Bid
prior to 8:30 a.m. on the date of the requested Competitive Advance or shall be
deemed to have rejected the offered Competitive Advances. Acceptance of a
Competitive Bid by Borrower or a Co-Borrower shall be irrevocable upon
communication thereof to the Administrative Agent. The Administrative Agent
shall promptly notify each of the Banks whose Competitive Bid has been accepted
by Borrower or the relevant Co-Borrower by telephone, which notification shall
promptly be confirmed in writing delivered in person or by telecopier to such
Banks.

          (k)     In the case of Eurodollar Margin Bids, the Administrative
Agent shall determine the Eurodollar Rate (as the case may be) on the date which
is two Eurodollar Banking Days prior to the date of the proposed Competitive
Advance, and shall promptly thereafter notify Borrower or the relevant Co-
Borrower and the Banks whose Competitive Bids were accepted by Borrower or the
relevant Co-Borrower of such Eurodollar Rate.

          (l)     A Bank whose Competitive Bid has been accepted shall make the
Competitive Advance in accordance with the Competitive Bid Request and with its
Competitive Bid, subject to the applicable conditions set forth in this
Agreement by making funds immediately available to the Administrative Agent at
the Administrative Agent's Office in the amount of such Competitive Advance not
later than 12:00 noon, California local time, on the date set forth in the
Competitive Bid Request.  The Administrative Agent shall then promptly credit
the Competitive Advance in immediately available funds to the relevant Deposit
Account.

          (m)     The Administrative Agent shall notify Borrower and the Banks
promptly after any Competitive Advance is made of the amounts and maturity of
such Competitive Advances and the identity of the Banks making such Competitive
Advances.

          (n)     The Competitive Advances made by each Bank shall be evidenced
by that Bank's Competitive Advance Note.

          2.6  Swing Line.  (a)  Subject to the terms and conditions set forth
               ----------
herein, from the Closing Date through the day prior to the Maturity Date the
Swing Line Bank shall make Swing Line Loans to Borrower and each of the Co-
Borrowers in such amounts as they may request which do not result in the
Outstanding Obligations being in excess of the then effective Commitment,
provided that (i) after giving effect to each Swing Line Loan, the Swing Line
--------
Outstandings shall not exceed $50,000,000, (ii) without the consent of all of
the Banks, no Swing Line Loan may be made during the continuation of an Event of
Default and (iii) the Swing Line Bank has not given at least twenty-four  hours
prior notice to Borrower and the Co-Borrowers that availability under the Swing
Line is suspended or terminated.  Borrower and the Co-Borrowers may borrow,
repay and reborrow under this Section.  Unless notified to the contrary by the
Swing Line Bank, borrowings under the Swing Line may be made in amounts which
are integral multiples of $100,000 upon telephonic request by a Responsible
Official of Borrower or the relevant Co-Borrower made to the Administrative
Agent not later than 3:00 p.m., California local time, on the Banking Day of the
requested borrowing (which telephonic request shall be promptly confirmed in
writing by telecopier), provided that if the requested Swing Line Loan is to be

credited to an account which is not with the Swing Line Bank, the request must
be submitted by 11:30 a.m., California local time.  Promptly after receipt of
such a request for borrowing,

                                      -38-
<PAGE>

the Administrative Agent shall provide telephonic verification to the Swing Line
Bank that, after giving effect to such request, the Outstanding Obligations will
not exceed the Commitment (and such verification shall be promptly confirmed in
writing by telecopier). Unless notified to the contrary by the Swing Line Bank,
each repayment of a Swing Line Loan shall be in an amount which is an integral
multiple of $100,000. If Borrower or the relevant Co-Borrower instructs the
Swing Line Bank to debit its demand deposit account at the Swing Line Bank in
the amount of any payment with respect to a Swing Line Loan, or the Swing Line
Bank otherwise receives repayment, after 3:00 p.m., California local time, on a
Banking Day, such payment shall be deemed received on the next Banking Day. The
Swing Line Bank shall promptly notify the Administrative Agent of the Swing Loan
Outstandings each time there is a change therein or if it suspends or terminates
availability under the Swing Line.

          (b) Swing Line Loans shall bear interest at a fluctuating rate per
annum equal to the Base Rate plus the Base Rate Margin minus one percent per
                             ----                      -----
annum.  Interest shall be payable on such dates, not more frequent than monthly,
as may be specified by the Swing Line Bank and in any event on the Maturity
Date.  The Swing Line Bank shall be responsible for invoicing Borrower for such
interest.  Interest payable on Swing Line Loans is solely for the account of the
Swing Line Bank (subject to clause (d) below).

          (c) The Swing Line Loans shall be payable within five Banking Days
after demand made by the Swing Line Bank and in any event on the Maturity Date
or any earlier date when all other Obligations are due.

          (d) Upon the making of a Swing Line Loan in accordance with Section
2.6(a), each Bank shall be deemed to have purchased from the Swing Line Bank a
participation therein in an amount equal to that Bank's Pro Rata Share times the
                                                                       -----
amount of the Swing Line Loan.  Upon demand made by the Swing Line Bank through
the Administrative Agent, each Bank shall, according to its Pro Rata Share,
promptly provide to the Swing Line Bank its purchase price therefor in an amount
equal to its participation therein.  The obligation of each Bank to so provide
its purchase price to the Swing Line Bank shall be absolute and unconditional
(subject only to the making of a demand upon that Bank by the Swing Line Bank)
and shall not be affected by the occurrence of a Default or Event of Default;
provided that no Bank shall be obligated to purchase its Pro Rata Share of (i)
--------
Swing Line Loans to the extent that Swing Line Outstandings are in excess of
$50,000,000 or to the extent that the sum of the Indebtedness evidenced by the
                                      ---
Notes plus the Aggregate Effective Amount of all outstanding Letters of Credit
      ----
plus the Swing Line Outstandings exceeds the Commitment (as in effect on the
----
date of the making of the related Swing Line Loan) and (ii) any Swing Line Loan
made (absent the consent of all of the Banks) during the continuation of an
Event of Default.  Each Bank that has provided to the Swing Line Bank the
purchase price due for its participation in Swing Line Loans shall thereupon
acquire a pro rata participation, to the extent of such payment, in the claim of
the Swing Line Bank against Borrower and the Co-Borrowers for principal and
interest and shall share, in accordance with that pro rata participation, in any
principal payment made by Borrower or the Co-Borrowers with respect to such
claim and in any interest payment made by Borrower or the Co-Borrowers (but only
with respect to periods subsequent to the date such Bank paid the Swing Line
Bank its purchase price) with respect to such claim.

          (e) Upon any demand for payment of the Swing Line Outstandings by the
Swing Line Bank (unless Borrower or the relevant Co-Borrower has made other
arrangements acceptable to

                                      -39-
<PAGE>

the Swing Line Bank to reduce the Swing Line Outstandings to $0), Borrower or
the relevant Co-Borrower shall request a Loan pursuant to Section 2.1(a)
sufficient to repay all Swing Line Outstandings (and, for this purpose, Section
2.1(d) shall not apply). In each case, the Administrative Agent shall
automatically provide the respective Committed Advances made by each Bank to the
Swing Line Bank (which the Swing Line Bank shall then apply to the Swing Line
Outstandings). In the event that Borrower and the Co-Borrowers fail to request a
Loan within the time specified by Section 2.2 on any such date, the
Administrative Agent may, but is not required to, without notice to or the
consent of Borrower or the Co-Borrowers, cause Committed Advances to be made by
the Banks under the Commitment in amounts which are sufficient to reduce the
Swing Line Outstandings as required above. The conditions precedent set forth in
Article 8 shall not apply to Advances to be made by the Banks pursuant to the
three preceding sentences but the Banks shall not be obligated to make such
Advances to the extent that the conditions set forth in Section 2.6(a)(i), (ii)
and (iii) were not satisfied as to any Swing Line Loan which is part of such
Swing Line Outstandings. The proceeds of such Advances shall be paid directly to
the Swing Line Bank for application to the Swing Line Outstandings.

          2.7  Co-Borrowers.  Atlantic City and Detroit are each hereby
               ------------
designated as joint and several direct Co-Borrowers under this Agreement, with
the right to request Loans and Letters of Credit through the Administrative
Agent directly from the Banks and the Issuing Bank, subject to the terms and
conditions set forth herein, provided that (a) each Loan and Letter of Credit
                             -------- ----
made hereunder to Atlantic City, Detroit or any other Co-Borrower shall be used
solely and directly to finance the development, construction or operation of
hotel/casino properties owned by that Co-Borrower, and (b) the liability of
Detroit is limited to that portion of the Obligations which are used, directly
or indirectly, to finance the design, development, construction or operation of
the Detroit Project or which are actually borrowed or received by Detroit.  From
time to time following the Closing Date, Borrower may designate one or more
Guarantors to be joint and several direct Co-Borrowers hereunder by written
request to the Administrative Agent accompanied by (a) an executed Assumption
Agreement and Notes executed by the designated Guarantor, (b) a certificate of
good standing of the designated Guarantor in the jurisdiction of its
incorporation, (c) a certified corporate authority resolution covering the
execution and delivery of the Assumption Agreement and Notes, (d) a written
consent to the Assumption Agreement executed by each other Guarantor, and (e) an
appropriate written legal opinion similar to the Opinions with respect to the
Co-Borrower and the Assumption Agreement.  The Administrative Agent shall
promptly notify the Banks of such request, together with copies of such of the
foregoing as any Bank may request and the designated Guarantor shall become a
Co-Borrower hereunder.

          2.8  Voluntary Reduction of Commitment.  Borrower and the Co-
               ---------------------------------
Borrowers shall have the right, at any time and from time to time, without
penalty or charge, upon at least three Banking Days' prior written notice by a
Responsible Official of Borrower and the Co-Borrowers to the Administrative
Agent, voluntarily to reduce, permanently and irrevocably, in aggregate
principal amounts in an integral multiple of $1,000,000 but not less than
$5,000,000, or to terminate, all or a portion of the then undisbursed portion of
the Commitment; provided that the Commitment may not be so reduced below an
                --------
amount equal to the sum of (i) the aggregate principal amount outstanding under
                    --- --
the Notes, plus (ii) the Aggregate Effective Amount of all outstanding Letters
           ----
of Credit plus (c) the Swing Line Outstandings.  The Administrative Agent shall
          ----
promptly notify the Banks of any reduction or termination of the Commitment
under this Section.

                                      -40-
<PAGE>

          2.9  Optional Termination of Commitment.  Following the occurrence
               ----------------------------------
of a Change in Control, the Requisite Banks may in their sole and absolute
discretion elect to terminate the Commitment during the sixty day period
immediately subsequent to the later of (a) such occurrence or (b) the earlier of
                              ----- --                                -------
(i) receipt of written notice to the Administrative Agent of the Change in
Control from Borrower and the Co-Borrowers, or (ii) if no such notice has been
received by the Administrative Agent, the date upon which the Administrative
Agent has actual knowledge thereof.  In the event that the Banks elect to so
terminate the Commitment, the Commitment shall be terminated effective on the
date which is sixty days subsequent to written notice from the Administrative
Agent to Borrower and the Co-Borrowers thereof.

          2.10  Extension of Maturity Date.  At any time following the one
                --------------------------
year anniversary of the Closing Date, the Maturity Date may be extended for one
year at Borrower's and the Co-Borrowers' election with the written consent of
all of the Banks (which may be withheld in the sole and absolute discretion of
each Bank).  Not earlier than 60 days prior to the then current Maturity Date,
and provided that Borrower and the Co-Borrowers are then in compliance with
    --------
Section 7.1, Borrower and the Co-Borrowers may deliver to the Administrative
Agent who will deliver to each of the Banks a written request for a one year
extension of the Maturity Date together with a Certificate of a Responsible
Official signed by a Senior Officer on behalf of Borrower and the Co-Borrowers
stating that the representations and warranties contained in Article 4 (other
                                                                        -----
than representations and warranties which expressly speak as of a particular
----
date or are no longer true and correct as a result of a change which is not a
violation of this Agreement) are true and correct on and as of the date of such
Certificate.  Within 30 days following the delivery of such Certificate, but in
any event not sooner than 45 nor later than 15 days prior to the then current
Maturity Date, each Bank shall notify the Administrative Agent whether (in its
sole and absolute discretion) it consents to such request.  Each Bank which
fails to respond to any such request for extension shall be deemed to have
refused to consent thereto.  After receiving the notifications from all of the
Banks or the expiration of such period, whichever is earlier, the Administrative
Agent shall notify Borrower, the Co-Borrower and the Banks of the results
thereof.

          If all of the Banks have consented to the extension then the Maturity
Date shall be extended for one year.

          If Banks holding at least 66 2/3% of the Commitment consent to the
request for extension, but other Banks (each a "Non-Consenting Bank") notify the
Administrative Agent that they will not consent to the request for extension (or
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 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

                                      -41-
<PAGE>

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 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

                                      -42-
<PAGE>

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.

          2.13  Senior Indebtedness.  The Obligations shall be and hereby are
                -------------------

     before and after judgment, and before and after the commencement of any
     proceeding under any Debtor Relief Law, with interest on overdue interest
     at the Default Rate to the fullest extent permitted by applicable Laws.

                   (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
                                                   ----
     Eurodollar Margin.

                   (d)  Interest accrued on each Competitive Advance shall be
     due and payable on the maturity date of the Competitive Advance. Except as
     otherwise provided in Section 3.9, the unpaid principal amount of each
     Competitive Advance shall bear interest at the fixed interest rate or the
     margin over the Eurodollar Rate specified in the related Competitive Bid.

                   (e)  If not sooner paid, the principal Indebtedness evidenced
     by the Notes shall be payable as follows:

          Obligations at any time exceed the then applicable Commitment, shall
          be payable immediately;

                        (ii)   the principal amount of each Competitive Advance
          shall be payable on the maturity date specified in the related
          Competitive Bid; and

     voluntarily be paid or prepaid in whole or in part without premium or
     penalty, except that with respect to any voluntary prepayment under this
              ------
     Section 3.1(f), (i) any partial prepayment shall be not less than
     $5,000,000, or in integral multiples of $1,000,000 which are in excess of
     $5,000,000, (ii) the Administrative Agent shall have received written
     notice of any prepayment by 9:00 a.m., California local time, on the
     Banking Day prior to the date of prepayment (which must be a Banking Day)
     in the case of a Base Rate Loan, and, in the case of a Eurodollar Rate
     Loan, three Banking Days before the date of prepayment, which notice shall
     identify the date and amount of the prepayment and the Loan(s) being
     prepaid, (iii) each prepayment of principal on any Eurodollar Rate Loan
     shall be accompanied by payment of interest accrued to the date of payment

     or any part of any Eurodollar Rate Loan on a day other than the last day of
     the applicable Eurodollar Period shall be subject to Section 3.8(e).
     Promptly following receipt of a notice of prepayment under clause (ii)
     above, the Administrative Agent shall notify each Bank by telephone or
     telecopier (and if by telephone, promptly confirmed by telecopier) of the
     date and amount thereof.

     prior written consent of the Bank making such Competitive Advance.

                   (h)  Each payment of principal by Borrower or Co-Borrower
     hereunder shall be applied ratably to the Advances made to Borrower or that
     Co-Borrower which are then due and payable, provided that if the
                                                 --------
     Obligations are then accelerated or have deemed to have been accelerated,

America.  Such upfront fees are for the credit facilities committed by each Bank
under this Agreement and are fully earned when paid.  The upfront fees paid to
each Bank are solely for its own account and are nonrefundable.

          3.4  Facility Fees.  During the period between April 10, 2000 and
               -------------
the date which is the earlier of (a) May 25, 2000 or (b) the day prior to the
Closing Date no facility fees shall accrue.

                                      -45-

Thereafter, for a forty-five day period (unless the Closing Date occurs or has
earlier occurred), Borrower and the Co-Borrowers shall pay to the Administrative
Agent, for the ratable accounts of the 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 times the principal amount of the Commitment. In any event,
                  -----
from the Closing Date, Borrower and the Co-Borrowers shall pay to the
Administrative Agent, for the ratable accounts of the Banks pro rata according
to their Pro Rata Share, a facility fee equal to the full Facility Fee Rate in
effect from time to time times the principal amount of the Commitment. The
                         -----
facility fees shall be payable quarterly in arrears on each Quarterly Payment
Date, on the Maturity Date upon the date of any partial reduction or termination
of the Commitment pursuant to Sections 2.8, 2.9 or 11.27.

          3.5  Letter of Credit Fees.  With respect to each Letter of Credit,
               ---------------------
Borrower and the Co-Borrowers shall pay the following fees:

                   (a)  concurrently with the issuance of each Standby Letter of
          Credit, a letter of credit issuance fee to the Issuing Bank for the
          sole account of the Issuing Bank, in an amount set forth in a letter
          agreement between Borrower and the Issuing Bank;

                   (b)  concurrently with the issuance of each Standby Letter of
          Credit, to the Administrative Agent for the ratable account of the
          Banks in accordance with their Pro Rata Share, a standby letter of
          credit fee in an amount equal to the applicable Standby Letter of
          Credit Fee per annum as of the date of such issuance times the face
                                                               -----
          amount of such Standby Letter of Credit through the termination or
          expiration of such Standby Letter of Credit, which the Administrative
          Agent shall promptly pay to the Banks; and

                   (c)  concurrently with each issuance, negotiation, drawing or
          amendment of each Commercial Letter of Credit, to the Issuing Bank for
          the sole account of the Issuing Bank, issuance, negotiation, drawing
          and amendment fees in the amounts set forth from time to time as the
          Issuing Bank's published scheduled fees for such services.

Each of the fees payable with respect to Letters of Credit under this Section is
earned when due and is nonrefundable.

          3.6  Agency Fees. On the Closing Date and annually thereafter,
               -----------
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

                                      -46-
<PAGE>

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.

          3.8  Eurodollar Costs and Related Matters.
               ------------------------------------

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

                                      -47-
<PAGE>

          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 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 Agent), Borrower and the Co-Borrowers shall pay
     to such Bank such additional amount or 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 Advance in
     the Designated Eurodollar Market).  A statement of any Bank claiming
     compensation 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.

                   (c)  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 impossible for such Bank or its Eurodollar
     Lending Office to make, maintain or fund its portion 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 charge interest rates based upon the Eurodollar Rate,
     and such Bank shall so notify the Administrative 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
     forthwith shall give notice thereof to the other Banks and Borrower. Upon
     receipt of such 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 (1) the
     last day of the Eurodollar Period(s) applicable to such Eurodollar Rate
     Advances if such Bank may lawfully continue to maintain and fund such
     Eurodollar Rate Advances to such

                                      -48-
<PAGE>

     day(s) or (2) immediately if such Bank may not lawfully continue to fund
     and maintain such Eurodollar Rate Advances to such day(s), provided that in
                                                                --------
     such event the conversion shall not be subject to payment of a prepayment
     fee under clause (e) of this Section. 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 cause that Bank to notify the
     Administrative Agent under this Section, and agrees to designate a
     different Eurodollar Lending Office if such designation 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, for the reasons set forth above, to make, maintain or fund
     its portion of any Eurodollar Rate 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 Bank
     whose obligation to make Eurodollar Rate Advances has been suspended under
     this Section shall promptly notify the Administrative Agent and Borrower of
     the cessation of the Special Eurodollar Circumstance which gave rise to
     such suspension.

                   (d)  If, with respect to any proposed Eurodollar Rate Loan:

                   (1)  the Administrative Agent reasonably determines that, by
          reason of 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 being offered
          to any Bank in the Designated Eurodollar Market for the applicable
          Eurodollar Period; or

                   (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 Request for Competitive Bids, 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

                                      -49-
<PAGE>

     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
     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, Competitive Advances 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 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 (other than payments with respect to Swing Line Loans, which
                 -----
     must be paid directly to the Swing Line Bank and received by 3:00 p.m.),
     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.

                                      -51-
<PAGE>

                   (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 in tangible 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 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 provide Borrower with the appropriate form or forms
     required by Section 11.21, to the extent 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 other Party is obligated by applicable Laws to make any
     deduction or withholding on account of 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 such additional amount to that Bank as is necessary to result in that
     Bank's receiving a net 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 in an excess
     payment or credit to that Bank on account of such Taxes, that Bank shall
     promptly 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 removal in accordance
     with Section 11.27; provided that Borrower or the relevant Party 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.

          3.13  Funding Sources.  Nothing in this Agreement shall be deemed to
                ---------------
obligate any Bank to obtain the funds for any Loan or Advance in any particular
place or manner or to constitute a representation by any Bank that it has
obtained or will obtain the funds for any Loan or Advance in any particular
place or manner, provided 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 Advances in compliance with applicable Laws and
that the making of its Advances will not constitute "prohibited transactions" as
such term is defined in ERISA.

          3.14  Failure to Charge Not Subsequent Waiver.  Any decision by the
                ---------------------------------------
Administrative Agent or any Bank not to require payment of any interest

(including interest at the Default Rate), fee, cost or other amount payable
----------
under any Loan Document, or to calculate any amount payable by a particular
method, on any occasion shall in no way limit or be deemed a waiver of the
Administrative Agent's or such Bank's right to require full payment of any
interest (including interest at the Default Rate), fee, cost or other amount
          ---------
payable under any Loan Document, or to calculate an amount payable by another
method that is not inconsistent with this Agreement, on any other or subsequent
occasion.

          3.15  Administrative Agent's Right to Assume Payments Will be Made by
                ---------------------------------------------------------------
Borrower and the Co-Borrowers.  Unless the Administrative Agent shall have
-----------------------------
been notified by Borrower and the Co-Borrowers prior to the date on which any
payment to be made by Borrower and the Co-Borrowers hereunder is due that
Borrower and the Co-Borrowers do not intend to remit such payment, the
Administrative Agent may, in its discretion, assume that Borrower and the Co-
Borrowers have remitted such payment when so due and the Administrative Agent
may, in its discretion and in reliance upon such assumption, make available to
each Bank on such payment date an amount equal to such Bank's share of such
assumed payment.  If Borrower and the Co-Borrowers have not in fact remitted
such payment to the Administrative Agent, each Bank shall forthwith on demand
repay to the Administrative Agent the amount of such assumed payment made
available to such Bank, together with interest thereon in respect of each day
from and including the date such amount was made available by the Administrative
Agent to such Bank to the date such amount is repaid to the Administrative Agent
at the Federal Funds Rate.

          3.16  Fee Determination Detail.  The Administrative Agent and any
                ------------------------
Bank shall provide reasonable detail to Borrower and the Co-Borrowers regarding
the manner in which the amount of any payment to the Creditors, or that Bank,
under Article 3 has been determined, concurrently with demand for such payment.

          3.17  Survivability.  All of Borrower's and the Co-Borrowers'
                -------------
obligations under Sections 3.7 and 3.8 shall survive for ninety days following
the date on which the Commitment is terminated, all Obligations hereunder are
fully paid and all Letters of Credit have expired.

Borrower is a corporation duly formed, validly existing and in good standing

constitute a Material Adverse Effect.  Borrower and each Guarantor have all
requisite corporate or other organizational power and authority to conduct their
business, to own and lease their Properties and to execute and deliver each Loan
Document to which each is a Party and to perform the Obligations.  All
outstanding shares of the capital stock of Borrower are duly authorized, validly

     indenture or loan or credit agreement or any other Contractual Obligation
     to which such party is a party or by which such party or any of its
     Property is bound or affected (except for the acceleration and payment in
     cash therefor of certain options to purchase equity securities of Mirage
     and the acceleration of certain compensation obligations of former
     employees of Mirage and other similar events which would not have a
     material adverse effect upon Mirage and its Subsidiaries taken as a whole);

and neither Borrower, the Co-Borrowers nor any Guarantor is in violation of, or
default under, any Requirement of Law or Contractual Obligation, or any
indenture, loan or credit agreement described in Section 4.2(e), in any respect
that constitutes a Material Adverse Effect.

          4.3  No Governmental Approvals Required.  Except as set forth in

qualification with, any Governmental Agency is or will be required to authorize
or permit under applicable Laws the execution, delivery and performance by
Borrower and its Restricted Subsidiaries of the Loan Documents to which it is a
Party.  Except as set forth in Schedule 4.3, all authorizations from, or filings

          4.4  Subsidiaries.
               ------------

                   (a)  Schedule 4.4 hereto correctly sets forth the names, form
     of legal entity, ownership and jurisdictions of organization of all
     Subsidiaries of Borrower. Except as described in Schedule 4.4, Borrower
     does not own any capital stock, equity interest or debt security which is
     convertible, or exchangeable, for capital stock or equity interests in any
     Person. Unless otherwise indicated in Schedule 4.4, all of the outstanding
     shares of capital stock, or all of the units of equity interest, as the
     case may be, of each Subsidiary are owned of record and beneficially by
     Borrower, there are no outstanding options, warrants or other rights to
     purchase capital stock of any such Subsidiary, and all such shares or
     equity interests so owned are duly authorized, validly issued, fully paid
     and non-assessable, and were issued in compliance with all applicable state
     and federal securities and other Laws, and are free and clear of all Liens,
     except for Permitted Encumbrances.

                   (b)  Each Restricted Subsidiary of Borrower is a business
     entity duly formed, validly existing and in good standing under the Laws of
     its jurisdiction of organization, is duly qualified to do business as a
     foreign organization and is in good standing as such in each jurisdiction
     in which the conduct of its business or the ownership or leasing of its
     Properties makes such qualification necessary (except where the failure to
                                                    ------
     be so duly qualified and in good standing does not constitute a Material
     Adverse Effect), and has all requisite power and authority to conduct its
     business and to own and lease its Properties.

     with all Requirements of Law applicable to its business and has obtained
     all authorizations, consents, approvals, orders, licenses, and permits
     from, and each such Restricted Subsidiary has accomplished all filings,
     registrations, and qualifications with, or obtained exemptions from any of
     the foregoing from, any Governmental Agency that are necessary for the
     transaction of its business, except where the failure to be in such

     compliance, obtain such authorizations, consents, approvals, orders,
     licenses, and permits, accomplish such filings, registrations, and

          payable, without protest, presentment, notice of dishonor, demand or
          further notice of any kind, all of which are expressly waived by
          Borrower and each Co-Borrower.

               (b) Upon the occurrence, and during the continuance, of any Event
     of Default described in Section 9.1(k):

               (1) the Commitment to make Advances, the obligation of the
          Issuing Bank to issue Letters of Credit, the obligation of the Swing
          Line Bank to make Swing Line Loans and all other obligations of the
          Creditors and all rights of Borrower, the Co-Borrowers and any other
          Parties under the Loan Documents shall terminate without notice to or
          demand upon Borrower or any Co-Borrower, which are expressly waived by
          Borrower and the Co-Borrowers, except that all of the Banks may waive
                                         ------
          the Event of Default or, without waiving, determine, upon terms and
          conditions satisfactory to all the Banks, to reinstate the Commitment
          and such other obligations and rights and make further Advances and to
          cause the Issuing Bank to issue further Letters of Credit, which
          determination shall apply equally to, and shall be binding upon, all
          the Banks;

               (2) an amount equal to the aggregate amount of all outstanding
          Letters of Credit shall be immediately due and payable to the Issuing
          Bank without notice to or demand upon Borrower or any Co-Borrower,
          which are expressly waived by Borrower and the Co-Borrowers, to be
          held by the Issuing Bank in an interest-bearing cash collateral
          account as collateral hereunder; and

               (3) the unpaid principal of all Notes, all interest accrued and
          unpaid thereon and all other amounts payable under the Loan Documents
          shall be forthwith due and payable, without protest, presentment,
          notice of dishonor, demand or further notice of any kind, all of which
          are expressly waived by Borrower and the Co-Borrowers.

               (c) Upon the occurrence, and during the continuance, of any Event
     of Default, the Creditors, or any of them, without notice to (except as
                                                                   ------
     expressly provided for in any Loan Document) or demand upon Borrower or any
     Co-Borrower, which are expressly waived by Borrower and the Co-Borrowers

     (except as to notices expressly provided for in any Loan Document), may
      ------
     proceed (but only with the consent of the Requisite Banks) to protect,
     exercise and enforce their rights and remedies under the Loan Documents
     against Borrower, the Co-Borrowers and any other Party and such other
     rights and remedies as are provided by Law or equity.

               (d) The order and manner in which the Creditors' rights and
     remedies are to be exercised shall be determined by the Requisite Banks in
     their sole discretion, and all payments received by the Creditors, or any
     of them, shall be applied first to the costs and expenses (including
     reasonable attorneys' fees and disbursements and the reasonably allocated
     costs of attorneys employed by any of the Creditors) of the Creditors, and
     thereafter paid pro rata to the Banks in the same proportions that the
     aggregate Obligations owed to each Bank under the Loan Documents bear to
     the aggregate Obligations owed under the Loan Documents to all the

                                      -77-
<PAGE>

     Banks, without priority or preference among the Banks. Regardless of how
     each Bank may treat payments for the purpose of its own accounting, for the
     purpose of computing the Obligations hereunder and under the Notes,
     payments shall be applied first, to the costs and expenses of the
                               -----
     Creditors, as set forth above, second, to the payment of accrued and unpaid
                                    ------
     interest due under any Loan Documents to and including the date of such
     application (ratably, and without duplication, according to the accrued and
     unpaid interest due under each of the Loan Documents), and third, to the
                                                                -----
     payment of all other amounts (including principal and fees) then owing to
     the Creditors under the Loan Documents.  Amounts due to a Bank under a
     Related Swap Agreement shall be considered a principal amount for purposes
     of the preceding sentence.  No application of payments will cure any Event
     of Default, or prevent acceleration, or continued acceleration, of amounts
     payable under the Loan Documents, or prevent the exercise, or continued
     exercise, of rights or remedies of the Banks hereunder or thereunder or at
     Law or in equity.

                           THE ADMINISTRATIVE AGENT
                           ------------------------


          10.1  Appointment and Authorization.  Subject to Section 10.8, each
                -----------------------------
Bank hereby irrevocably appoints and authorizes the Administrative Agent to take
such action as agent on its behalf and to exercise such powers under the Loan
Documents as are delegated to the Administrative Agent by the terms thereof or
are reasonably incidental, as determined by the Administrative Agent, thereto.
This appointment and authorization is intended solely for the purpose of
facilitating the servicing of the Loans and does not constitute appointment of
the Administrative Agent as trustee for any Bank or as representative of any
Bank for any other purpose and, except as specifically set forth in the Loan
                                ------
Documents to the contrary, the Administrative Agent shall take such action and
exercise such powers only in an administrative and ministerial capacity.

          10.2  Administrative Agent and Affiliates.  Bank of America (and
                -----------------------------------
each successor Administrative Agent) has the same rights and powers under the
Loan Documents as any other Bank and may exercise the same as though it were not
the Administrative Agent, and the term "Bank" or "Banks" includes Bank of
America in its individual capacity.  Bank of America (and each successor
Administrative Agent) and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of banking, trust or other business with
Borrower, any Subsidiary thereof, or any Affiliate of Borrower or any Subsidiary
thereof, as if it were not the Administrative Agent and without any duty to
account therefor to the Banks.  Bank of America (and each successor
Administrative Agent) need not account to any other Bank for any monies received
by it for reimbursement of its costs and expenses as Administrative Agent
hereunder, or for any monies received by it in its capacity as a Bank hereunder.
The Administrative Agent shall not be deemed to hold a fiduciary or other
special relationship with any Bank and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or otherwise exist against the Administrative Agent.

          10.3  Proportionate Interest in any Collateral.  The Administrative
                ----------------------------------------
Agent, on behalf of all the Banks, shall hold in accordance with the Loan
Documents all items of any collateral or interests therein received or held by
the Administrative Agent.  Subject to the Administrative Agent's and the Banks'
rights to reimbursement for their costs and expenses hereunder (including
                                                                ---------
reasonable attorneys' fees and disbursements and other professional services and
the reasonably allocated costs of attorneys employed by the Administrative Agent
or a Bank) and subject to the application of payments in accordance with Section
9.2(d), each Bank shall have an interest in the Banks' interest in the
collateral or interests therein in the same proportions that the aggregate
Obligations owed such Bank under the Loan Documents bear to the aggregate
Obligations owed under the Loan Documents to all the Banks, without priority or
preference among the Banks, except that Obligations owed to any Bank under a
                            ------
Related Swap Agreement shall be secured on an equal, ratable and  pari passu
                                                                  ---- -----
basis with all other Obligations up to an amount equal to the Administrative
Agent's then customary credit risk factor for Swap Agreements times the notional
amount of Indebtedness covered by such Related Swap Agreement and shall be
secured on a subordinate basis as to amounts in excess of such amount.

          10.4  Banks' Credit Decisions.  Each Bank agrees that it has,
                -----------------------
independently and without reliance upon the Administrative Agent, any other
Creditor or the directors, officers, agents, employees or attorneys thereof, and
instead in reliance upon information supplied to it by or on behalf of Borrower

                                      -79-
<PAGE>

and its Subsidiaries and upon such other information as it has deemed
appropriate, made its own independent credit analysis and decision to enter into
this Agreement.  Each Bank also agrees that it shall, independently and without
reliance upon the Administrative Agent, any other Creditor or the directors,
officers, agents, employees or attorneys thereof, continue to make its own
independent credit analyses and decisions in acting or not acting under the Loan
Documents.

          10.5  Action by Administrative Agent.
                ------------------------------

               (a) Absent actual knowledge of the Administrative Agent of the
     existence of a Default, the Administrative Agent may assume that no Default
     has occurred and is continuing, unless the Administrative Agent has
     received notice from Borrower and the Co-Borrowers stating the nature of
     the Default or has received notice from a Bank stating the nature of the
     Default and that such Bank considers the Default to have occurred and to be
     continuing.

               (b) The Administrative Agent has only those obligations under the
     Loan Documents as are expressly set forth therein.

               (c) Except for any obligation expressly set forth in the Loan
                   ------
     Documents and as long as the Administrative Agent may assume that no Event
     of Default has occurred and is continuing, the Administrative Agent may,
     but shall not be required to, exercise its discretion to act or not act,

     except that the Administrative Agent shall be required to act or not act
     ------
     upon the instructions of the Requisite Banks (or of all the Banks, to the
     extent required by Section 11.2) and those instructions shall be binding
     upon the Administrative Agent and all the Banks, provided that the
                                                      --------
     Administrative Agent shall not be required to act or not act if to do so
     would be contrary to any Loan Document or to applicable Law or could
     result, in the judgment of the Administrative Agent, in a material risk of
     liability to the Administrative Agent.

               (d) If the Administrative Agent has received a notice specified
     in clause (a), the Administrative Agent shall immediately give notice
     thereof to the Banks and shall act or not act upon the instructions of the
     Requisite Banks (or of all the Banks, to the extent required by Section
     11.2), provided that the Administrative Agent shall not be required to act
            --------
     or not act if to do so would be contrary to any Loan Document or to
     applicable Law or could result, in the judgment of the Administrative
     Agent, in a material risk of liability to the Administrative Agent, and

     except that if the Requisite Banks (or all the Banks, if required under
     ------
     Section 11.2) fail, for five Banking Days after the receipt of notice from
     the Administrative Agent, to instruct the Administrative Agent, then the
     Administrative Agent, in its sole discretion, may act or not act as it
     deems advisable for the protection of the interests of the Banks.

               (e) The Administrative Agent shall have no liability to any Bank
     for acting, or not acting, as instructed by the Requisite Banks (or all the
     Banks, if required under Section 11.2), notwithstanding any other provision
     hereof.

          10.6  Liability of Administrative Agent.  Neither the Administrative
                ---------------------------------
Agent nor any of its directors, officers, agents or employees shall be liable
for any action taken or not taken by them

                                      -80-
<PAGE>

under or in connection with the Loan Documents, except for their own gross
                                                ------
negligence or willful misconduct. Without limitation on the foregoing, the
Administrative Agent and its directors, officers, agents and employees:

               (a) May treat the payee of any Note as the holder thereof until
     the Administrative Agent receives notice of the assignment or transfer
     thereof, in form satisfactory to the Administrative Agent, signed by the
     payee, and may treat each Bank as the owner of that Bank's interest in the
     Obligations for all purposes of this Agreement until the Administrative
     Agent receives notice of the assignment or transfer thereof, in form
     satisfactory to the Administrative Agent, signed by that Bank;

               (b) May consult with legal counsel (including in-house legal
                                                   ---------
     counsel), accountants (including in-house accountants) and other
                            ---------
     professionals or experts selected by it, or with legal counsel, accountants
     or other professionals or experts for Borrower and/or its Subsidiaries or
     the Banks, and shall not be liable for any action taken or not taken by it
     in good faith in accordance with any advice of such legal counsel,
     accountants or other professionals or experts;

               (c) Shall not be responsible to any Bank for any statement,
     warranty or representation made in any of the Loan Documents or in any
     notice, certificate, report, request or other statement (written or oral)
     given or made in connection with any of the Loan Documents;

               (d) Shall have no duty to ask or inquire as to the performance or
     observance by Borrower or its Subsidiaries of any of the terms, conditions
     or covenants of any of the Loan Documents or to inspect any collateral or
     the Property, books or records of Borrower or its Subsidiaries;

               (e) Will not be responsible to any Bank for the due execution,
     legality, validity, enforceability, genuineness, effectiveness, sufficiency
     or value of any Loan Document, any other instrument or writing furnished
     pursuant thereto or in connection therewith, or any collateral;

               (f) Will not incur any liability by acting or not acting in
     reliance upon any Loan Document, notice, consent, certificate, statement,
     request or other instrument or writing believed in good faith by it to be
     genuine and signed or sent by the proper party or parties; and

               (g) Will not incur any liability for any arithmetical error in
     computing any amount paid or payable by the Borrower or any Subsidiary or
     Affiliate thereof or paid or payable to or received or receivable from any
     Bank under any Loan Document, including, principal, interest, commitment
                                   ---------
     fees, Advances and other amounts; provided that, promptly upon discovery of
                                       --------
     such an error in computation, the Administrative Agent, the Banks and (to
     the extent applicable) Borrower and/or its Subsidiaries or Affiliates shall
     make such adjustments as are necessary to correct such error and to restore
     the parties to the position that they would have occupied had the error not
     occurred.

                                      -81-
<PAGE>

          10.7  Indemnification.  Each Bank shall, ratably in accordance with
                ---------------
its Pro Rata Share (if the Commitment is then in effect) or in accordance with
its proportion of the aggregate Indebtedness then evidenced by the Notes (if the
Commitment has then been terminated), indemnify and hold the Administrative
Agent and its directors, officers, agents, employees and attorneys harmless
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever (including, without limitation, attorneys' fees and
                   ---------
disbursements and allocated costs of attorneys employed by the Administrative
Agent) that may be imposed on, incurred by or asserted against it or them in
such capacity in any way relating to or arising out of the Loan Documents (other
than losses incurred by reason of the failure of Borrower and the Co-Borrowers
to pay the Indebtedness represented by the Notes) or any action taken or not
taken by it as Administrative Agent thereunder, except such as result from its
                                                ------
own gross negligence or willful misconduct.  Without limitation on the
foregoing, each Bank shall reimburse the Administrative Agent upon demand for
that Bank's Pro Rata Share of any out-of-pocket cost or expense incurred by the
Administrative Agent in connection with the negotiation, preparation, execution,
delivery, amendment, waiver, restructuring, reorganization (including a
                                                            ---------
bankruptcy reorganization), enforcement or attempted enforcement of the Loan
Documents, to the extent that Borrower, any Co-Borrower or any other Party is
required by Section 11.3 to pay that cost or expense but fails to do so upon
demand.  Nothing in this Section shall entitle the Administrative Agent to
recover any amount from the Banks if and to the extent that such amount has
theretofore been recovered from Borrower, and Co-Borrower or any other Party.
To the extent that the Administrative Agent is later reimbursed such cost or
expense by Borrower, a Co-Borrower or any other Party, it shall return the
amounts paid to it by the Banks in respect of such cost or expense.

          10.8  Successor Administrative Agent.  The Administrative Agent may,
                ------------------------------
and at the request of the Requisite Banks shall, resign as Administrative Agent
upon thirty days' notice to the Banks and Borrower.  If the Administrative Agent
shall resign as Administrative Agent under this Agreement, the Requisite Banks
shall appoint from among the Banks a successor Administrative Agent for the
Banks, which successor Administrative Agent shall be approved by Borrower (and
such approval shall not be unreasonably withheld or delayed), provided that, to
                                                              --------
the extent required by applicable Gaming Laws, the incumbent Administrative
Agent shall remain the collateral agent for the Creditors with respect to any
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 actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.  If (a) the Administrative Agent has
not been paid its agency fees under Section 3.6 or has not been reimbursed for
any expense reimbursable to it under Section 11.3, in either case for a period
of at least one year and (b) no successor Administrative Agent has accepted
appointment as Administrative Agent

                                      -82-
<PAGE>

by the date which is thirty days following a retiring Administrative Agent's
notice of resignation, the retiring Administrative Agent's resignation shall
nevertheless thereupon become effective and the Banks shall perform all of the
duties of the Administrative Agent hereunder until such time, if any, as the
Requisite Banks appoint a successor Administrative Agent as provided for above.

          10.9   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
                               --------
Business Days prior to entering into any such arrangement or agreement, the
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
Agreement.

          11.1  Cumulative Remedies; No Waiver.  The rights, powers,
                ------------------------------
privileges and remedies of the Creditors provided herein or in any Note or other
Loan Document are cumulative and not exclusive of any right, power, privilege or
remedy provided by Law or equity.  No failure or delay on the part of the
Administrative Agent or any Bank in exercising any right, power, privilege or
remedy may be, or may be deemed to be, a waiver thereof; nor may any single or
partial exercise of any right, power, privilege or remedy preclude any other or
further exercise of the same or any other right, power, privilege or remedy.
The terms and conditions of Article 8 hereof are inserted for the sole benefit
of the Creditors; the same may be waived in whole or in part, with or without
terms or conditions, in respect of any Loan or Letter of Credit without
prejudicing the Administrative Agent's or the Banks' rights to assert them in
whole or in part in respect of any other Loan.

          11.2  Amendments; Consents.  Each amendment, modification,
                --------------------
supplement, extension, termination, waiver, approval and consent under this
Agreement and the other Loan Documents shall be subject to the terms of all
applicable Laws, including Gaming Laws.  No amendment, modification, supplement,
extension, termination or waiver of any provision of this Agreement or any other
Loan Document, no approval or consent thereunder, and no consent to any
departure by the Borrower, the Co-Borrowers or any other Party therefrom, may in
any event be effective unless in writing signed by the Administrative Agent with
the approval of Requisite Banks (and, in the case of any amendment, modification

specific purpose given; and, without the approval in writing of all the Banks,
no amendment, modification, supplement, termination, waiver or consent may be

               (b) To postpone any date fixed for any payment of principal of,

     or extend beyond the Maturity Date;

               (d) To release the Guaranty or any material portion of any
     collateral for the Obligations, provided that if no Default or Event of
                                     --------
     Default exists, the Administrative Agent may without the consent of any
     Bank (and shall at the request of Borrower), (i) release its Lien in any
     personal property financed or leased by the Borrower or its Subsidiaries
     and granted a

Creditors.

          11.3  Costs, Expenses and Taxes.  Borrower and the Co-Borrowers
                -------------------------
shall pay within five Banking Days after demand, accompanied by an invoice
therefor, the reasonable costs and expenses of the Administrative Agent and the
Lead Arranger in connection with the negotiation, preparation, syndication,
execution and delivery of the Loan Documents and any amendment thereto or waiver
thereof.  Borrower and the Co-Borrowers shall also pay on demand, accompanied by
an invoice therefor, the reasonable costs and expenses of the Creditors in
connection with the refinancing, restructuring, reorganization (including a
                                                                ---------
bankruptcy reorganization) and enforcement or attempted enforcement of the Loan
Documents, and any matter related thereto.  The foregoing costs and expenses
shall include filing fees, recording fees, title insurance fees, appraisal fees,
search fees, and other out-of-pocket expenses and the reasonable fees and out-
of-pocket expenses of any legal counsel (including reasonably allocated costs of
                                         ---------
legal counsel employed by the Administrative Agent or any Bank), independent
public accountants and other outside experts retained by the Administrative
Agent or any Bank, whether or not such costs and expenses are incurred or
suffered by the Administrative Agent or any Bank in connection with or during
the course of any bankruptcy or insolvency proceedings of Borrower or any
Subsidiary thereof.  Such costs and expenses shall also include, in the case of
any amendment or waiver of any Loan Document requested by Borrower or the Co-
Borrowers, the administrative costs of the Administrative Agent reasonably
attributable thereto.  Borrower and the Co-Borrowers shall pay any and all
documentary and other taxes, excluding (i) taxes imposed on or measured in whole
                             ---------
or in part by overall net income, gross income or gross receipts and 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", (ii) 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 Governmental Agency and (iii) 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 provide Borrower with the appropriate
form or forms

                                      -85-
<PAGE>

required by Section 11.21, to the extent such forms are then required by
applicable Laws, and all costs, expenses, fees and charges payable or determined
to be payable in connection with the filing or recording of this Agreement, any
other Loan Document or any other instrument or writing to be delivered hereunder
or thereunder, or in connection with any transaction pursuant hereto or thereto,
and shall reimburse, hold harmless and indemnify on the terms set forth in 11.11
the Creditors from and against any and all loss, liability or legal or other
expense with respect to or resulting from any delay in paying or failure to pay
any such tax, cost, expense, fee or charge or that any of them may suffer or
incur by reason of the failure of any Party to perform any of its Obligations.
Any amount payable to the Administrative Agent or any Bank under this Section
shall bear interest from the second Banking Day following the date of demand for
payment at the Default Rate.

          11.4  Nature of Banks' Obligations.  The obligations of the Banks
                ----------------------------
hereunder are several and not joint or joint and several.  Nothing contained in
this Agreement or any other Loan Document and no action taken by the Creditors
or any of them pursuant hereto or thereto may, or may be deemed to, make the
Banks a partnership, an association, a joint venture or other entity, either
among themselves or with the Borrower, the Co-Borrowers or any Affiliate of
Borrower.  Each Bank's obligation to make any Advance pursuant hereto is several
and not joint or joint and several, and in the case of the initial Advance only
is conditioned upon the performance by all other Banks of their obligations to
make initial Advances.  A default by any Bank will not increase the Pro Rata
Share of any other Bank.  Any Bank not in default may, if it desires, assume in
such proportion as the nondefaulting Banks agree the obligations of any Bank in
default, but is not obligated to do so.  The Administrative Agent agrees that it
will use its best efforts either to induce the other Banks to assume the
obligations of a Bank in default or to obtain another Bank, reasonably
satisfactory to Borrower and the Co-Borrowers, to replace such a Bank in
default.

          11.5  Survival of Representations and Warranties.  All
                ------------------------------------------
representations and warranties contained herein or in any other Loan Document,
or in any certificate or other writing delivered by or on behalf of any one or
more of the Parties to any Loan Document, will survive the making of the Loans
hereunder and the execution and delivery of the Notes, and have been or will be
relied upon by the Administrative Agent and each Bank, notwithstanding any
investigation made by the Administrative Agent or any Bank or on their behalf.

          11.6  Notices.  Except as otherwise expressly provided in the Loan
                -------   ------
Documents, all notices, requests, demands, directions and other communications
provided for hereunder or under any other Loan Document must be in writing and
must be mailed, telegraphed, telecopied, dispatched by commercial courier or
delivered to the appropriate party at the address set forth on the signature
pages of this Agreement or other applicable Loan Document or, as to any party to
any Loan Document, at any other address as may be designated by it in a written
notice sent to all other parties to such Loan Document in accordance with this
Section.  Borrower and the Co-Borrower expressly agree that the credit
facilities provided hereunder are being provided for the joint convenience of
Borrower and its Restricted Subsidiaries, including the Co-Borrowers, and that
(despite the joint and several nature of the Obligations), it is expected that
Borrower shall administer the Advances and Letters of Credit on behalf of itself
and the Co-Borrowers.  Accordingly, Borrower and the Co-Borrowers agree that any
notice provided to Borrower hereunder shall be deemed to constitute the same
notice to the Co-Borrowers, without the requirement that separate notices be
provided to the Co-Borrowers. Except as otherwise expressly provided in any Loan
                              ------
Document, if any notice, request, demand, direction or other

                                      -86-
<PAGE>

communication required or permitted by any Loan Document is given by mail it
will be effective on the earlier of receipt or the fourth Banking Day after
deposit in the United States mail with first class or airmail postage prepaid;
if given by telegraph or cable, when delivered to the telegraph company with
charges prepaid; if given by telecopier, when sent; if dispatched by commercial
courier, on the scheduled delivery date; or if given by personal delivery, when
delivered.

          11.7  Execution of Loan Documents.  Unless the Administrative Agent
                ---------------------------
otherwise specifies with respect to any Loan Document, (a) this Agreement and
any other Loan Document may be executed in any number of counterparts and any
party hereto or thereto may execute any counterpart, each of which when executed
and delivered will be deemed to be an original and all of which counterparts of
this Agreement or any other Loan Document, as the case may be, when taken
together will be deemed to be but one and the same instrument and (b) execution
of any such counterpart may be evidenced by a telecopier transmission of the
signature of such party followed by prompt transmission of an original
signature.  The execution of this Agreement or any other Loan Document by any
party hereto or thereto will not become effective until counterparts hereof or
thereof, as the case may be, have been executed by all the parties hereto or
thereto.

     11.8  Binding Effect; Assignment.
           --------------------------

               (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 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

                                      -87-
<PAGE>

     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
     Committed Advance Note) to such assignee Bank, a Committed Advance Note
     evidencing that assignee Bank's Pro Rata Share and a Competitive Advance
     Note, and to the assigning Bank, a Committed Advance 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 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.

                                      -88-
<PAGE>

               (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 (or in Competitive Advances made by that
     Bank); 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 (E) change the
     definition of "Requisite Banks."

               (f) Notwithstanding anything in this Section to the contrary, the
     rights of the Banks to make assignments of, and grant participations in,
     their Pro Rata Shares of the Commitment shall be subject to the approval of
     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, 2.3 or 2.5, 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 shall utilize the Commitment
     of the Granting Bank (and, if such Loan is a Competitive Advance, shall be
     deemed to utilize the Commitments of all the Banks) to the same extent, and
     as if, such Loan were made by the Granting Bank.  Each party hereto hereby
     agrees that no SPC shall be liable for any indemnity or similar payment
     obligation under this Agreement (all liability for which shall remain with
     the related Granting Bank).  In furtherance of the

                                      -89-
<PAGE>

     foregoing, each party hereto hereby agrees (which agreement shall survive
     the termination of this Agreement) that, prior to the date that is one year
     and one day after the payment in full of all outstanding senior
     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 proceedings or similar proceedings
     under the laws of the United States or any State thereof, provided that 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,
                 ------------------
through the exercise of any right of setoff, banker's lien or counterclaim
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; provided 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 thereafter recovered from
the purchasing Bank by Borrower, any Co-Borrower or any Person claiming through
or succeeding to the rights of Borrower or a Co-Borrower, the purchase of a
participation shall be rescinded and the purchase price thereof shall be
restored to the extent of the recovery, but without

                                      -90-
<PAGE>

interest. Each Bank that purchases a participation in the Obligations pursuant
to this Section shall from 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 same
extent as though the purchasing Bank were the original owner of the Obligations
purchased. Borrower 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, banker's lien or
counterclaim with respect to the participation as fully as if the Bank were the
original owner of the Obligation purchased.

          11.11  Indemnity by Borrower and the Co-Borrowers.  Borrower and
                 ------------------------------------------
each Co-Borrower jointly and severally agrees to indemnify, save and hold
harmless the Administrative Agent and each Bank and their Affiliates and their
directors, officers, agents, attorneys and employees (collectively the

"Indemnitees") from and against:  (a) any and all claims, demands, actions or
------------
causes of action (except a claim, demand, action, or cause of action for any
                  ------
amount excluded from the definition of "Taxes" in Section 3.12(d)) if the claim,
demand, action or cause of action arises out of or relates to any act or
omission (or alleged act or omission) of Borrower, its Subsidiaries or any of
their officers, directors or stockholders relating to the Commitment, the use or
contemplated use of proceeds of any Loan, or the relationship of Borrower, the
Co-Borrowers and the Banks under this Agreement; (b) any administrative or
investigative proceeding by any Governmental Agency arising out of or related to
a claim, demand, action or cause of action described in clause (a) above; and
                                                                -
(c) any and all liabilities, losses, costs or expenses (including reasonable
                                                        ---------
attorneys' fees and the reasonably allocated costs of attorneys employed by any
Indemnitee and disbursements of such attorneys and other professional services)
that any Indemnitee suffers or incurs as a result of the assertion of any
foregoing claim, demand, action or cause of action; provided that no Indemnitee
                                                    --------
shall be entitled to indemnification under this Section for any loss caused by
its own gross negligence or willful misconduct or for any loss asserted against
it by another Indemnitee.  If any claim, demand, action or cause of action is
asserted against any Indemnitee, such Indemnitee shall promptly notify Borrower
and the Co-Borrowers, but the failure to so promptly notify Borrower and the Co-
Borrowers shall not affect their obligations under this Section unless such
failure materially prejudices Borrower's and the Co-Borrowers' right to
participate in the contest of such claim, demand, action or cause of action, as
hereinafter provided.  Such Indemnitee may (and shall, if requested by Borrower
and the Co-Borrowers in writing) contest the validity, applicability and amount
of such claim, demand, action or cause of action and shall permit Borrower and
the Co-Borrowers to participate in such contest.  Any Indemnitee that proposes
to settle or compromise any claim or proceeding for which Borrower or any Co-
Borrower may be liable for payment of indemnity hereunder shall give Borrower
and the Co-Borrowers written notice of the terms of such proposed settlement or
compromise reasonably in advance of settling or compromising such claim or
proceeding and shall obtain Borrower's and each Co-Borrowers prior consent
(which shall not be unreasonably withheld or delayed).  In connection with any
claim, demand, action or cause of action covered by this Section against more
than one Indemnitee, all such Indemnitees shall be represented by the same legal
counsel (which may be a law firm engaged by the Indemnitees or attorneys
employed by an Indemnitee or a combination of the foregoing) selected by the
Indemnitees and reasonably acceptable to Borrower and the Co-Borrowers;

provided, that if such legal counsel determines in good faith that representing
--------
all such Indemnitees would or could result in a conflict of interest under Laws
or ethical principles applicable to such legal counsel or that a defense or
counterclaim is available to an Indemnitee that is not available to all such
Indemnitees, then to the extent reasonably necessary to avoid such a conflict of
interest or to permit unqualified assertion of such a defense or counterclaim,
each

                                      -91-
<PAGE>

Indemnitee shall be entitled to separate representation by legal counsel
selected by that Indemnitee and reasonably acceptable to Borrower and the Co-
Borrowers, with all such legal counsel using reasonable efforts to avoid
unnecessary duplication of effort by counsel for all Indemnitees; and further
                                                                      -------
provided that the Administrative Agent (as an Indemnitee) shall at all times be
--------
entitled to representation by separate legal counsel (which may be a law firm or
attorneys employed by the Administrative Agent or a combination of the
foregoing).  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, the expiration or termination of all
Letters of Credit and the payment and performance of all other Obligations owed
to the Banks.

          11.12  Nonliability of the Banks.  Borrower and each Co-Borrower
                 -------------------------
acknowledges and agrees that:

               (a) Any inspections of any Property of Borrower and its
     Subsidiaries made by or through the Creditors are for purposes of
     administration of the Loans and Letters of Credit only and Borrower and its
     Affiliates are not entitled to rely upon the same (whether or not such
     inspections are at the expense of Borrower or its Subsidiaries);

               (b) By accepting or approving anything required to be observed,
     performed, fulfilled or given to the Creditors pursuant to the Loan
     Documents, neither the Administrative Agent nor the Banks shall be deemed
     to have warranted or represented the sufficiency, legality, effectiveness
     or legal effect of the same, or of any term, provision or condition
     thereof, and such acceptance or approval thereof shall not constitute a
     warranty or representation to anyone with respect thereto by the Creditors;

               (c) The relationship between Borrower and the Co-Borrowers and
     the Creditors is, and shall at all times remain, solely that of borrowers
     and lenders; neither the Administrative Agent nor the Banks shall under any
     circumstance be construed to be partners or joint venturers of Borrower or
     its Affiliates; neither the Administrative Agent nor the Banks shall under
     any circumstance be deemed to be in a relationship of confidence or trust
     or a fiduciary or other "special" relationship with Borrower or its
     Affiliates, or to owe any fiduciary duty to Borrower or its Affiliates;
     neither the Administrative Agent nor the Banks undertake or assume any
     responsibility or duty to Borrower or its Affiliates to select, review,
     inspect, supervise, pass judgment upon or inform Borrower or its Affiliates
     of any matter in connection with their Property or the operations of
     Borrower or its Affiliates; Borrower and its Affiliates shall rely entirely
     upon their own judgment with respect to such matters; and any review,
     inspection, supervision, exercise of judgment or supply of information
     undertaken or assumed by the Creditors in connection with such matters is
     solely for the protection of the Creditors and neither Borrower, the Co-
     Borrowers nor any other Person is entitled to rely thereon; and

               (d) The Creditors shall not be responsible or liable to any
     Person for any loss, damage, liability or claim of any kind relating to
     injury or death to Persons or damage to Property caused by the actions,
     inaction or negligence of Borrower and/or its Affiliates and Borrower and
     the Co-Borrowers hereby indemnify and hold the Creditors harmless on the
     terms set forth in Section 11.11 from any such loss, damage, liability or
     claim.

          11.13  No Third Parties Benefitted.  This Agreement is made for the
                 ---------------------------
purpose of defining and setting forth certain obligations, rights and duties of
Borrower, the Co-Borrowers and the Creditors in connection with the Loans, and
is made for the sole benefit of Borrower, the Co-Borrowers, the Creditors, and
the Creditors' successors and assigns.  Except as provided in Sections 11.8,
                                        ------
11.11, and 11.29 no other Person shall have any rights of any nature hereunder
or by reason hereof.

          11.14  Confidentiality.  Each Bank agrees to hold any confidential
                 ---------------
information that it may receive from Borrower and the Co-Borrowers pursuant to
this Agreement in confidence, except for disclosure:  (a) to other Banks (or,
                              ------
subject to appropriate confidentiality restrictions, Affiliates of any Bank);
(b) to legal counsel and accountants for Borrower and the Co-Borrowers or any
Bank; (c) to other professional advisors to Borrower and the Co-Borrowers or any
Bank, provided that the recipient has accepted such information subject to a
confidentiality agreement substantially similar to this Section; (d) to
regulatory officials having jurisdiction over that Bank; (e) to any Gaming Board
having regulatory jurisdiction over Borrower or its Subsidiaries, provided that
each Bank agrees to use its best efforts to notify Borrower and the Co-Borrowers
of any such disclosure unless prohibited by applicable Laws; (f) as required by
Law or legal process or in connection with any legal proceeding to which that
Bank and Borrower or any of its Subsidiaries are adverse parties; and (g) to
another financial institution in connection with a disposition or proposed
disposition to that financial institution of all or part of that Bank's
interests hereunder or a participation interest in its Notes, provided that the
recipient has accepted such information subject to a confidentiality agreement
substantially similar to this Section.  For purposes of the foregoing,
"confidential information" shall mean any information respecting Borrower or its
Subsidiaries reasonably considered by Borrower to be confidential, other than
                                                                   ----------
(i) information previously filed with any Governmental Agency and available to
the public, (ii) information previously published in any public medium from a
source other than, directly or indirectly, that Bank, and (iii) information
previously disclosed by Borrower or its Subsidiaries to any Person not
associated with Borrower without a confidentiality agreement or obligation
substantially similar to this Section.  Nothing in this Section shall be
construed to create or give rise to any fiduciary duty on the part of the
Creditors to Borrower or any other Party.

          11.15  Further Assurances.  Borrower and its Subsidiaries shall, at
                 ------------------
their expense and without expense to the Banks or the Administrative Agent, do,
execute and deliver such further acts and documents as the Requisite Banks or
the Administrative Agent from time to time reasonably require for the assuring
and confirming unto the Banks or the Administrative Agent of the rights hereby
created or intended now or hereafter so to be, or for carrying out the intention
or facilitating the performance of the terms of any Loan Document.

          11.16  Integration.  This Agreement, the other Loan Documents and
                 -----------
the letter agreements referred to in Sections 3.2, 3.3, 3.5 and 3.6, comprise
the complete and integrated agreements of the parties on the subject matter
hereof and supersedes all prior agreements, written or oral, on the subject
matter hereof.  In the event of any conflict between the provisions of this
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
                 -------------   ------
therein, each Loan Document shall be governed by, and construed and enforced in
accordance with, the local Laws of Nevada.

          11.18  Severability of Provisions.  Any provision in any Loan
                 --------------------------
Document 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
not part of this Agreement or the other Loan Documents for any other purpose.

                 -------------------
Documents.

          11.21  Foreign Banks and Participants.  Each Bank that is
                 ------------------------------
incorporated or otherwise organized under the Laws of a jurisdiction other than
the United States of America or any State thereof or the District of Columbia
shall deliver to Borrower (with a copy to the Administrative Agent), within
twenty (20) days 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 reasonably necessary, Form W-9), or any successor form(s),
 ---------
satisfactory to Borrower and the Co-Borrowers and the Administrative Agent that
no withholding under the federal income tax laws is required with respect to
such Bank.  Thereafter and from time to time, each such Bank shall upon request
by Borrower and the Co-Borrowers (a) promptly submit to Borrower and the Co-
Borrowers (with 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 time to time by the relevant United States taxing
authorities) as may then be available under then current United States laws and
regulations to avoid, or 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 from amounts payable to such Bank.  In the event that Borrower, the Co-
Borrowers 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

                                      -94-

Borrower, the Co-Borrowers and the Administrative Agent as would be required
under this Section if such financial institution were a Bank.

          11.22  Hazardous Material Indemnity.  Borrower and each Co-Borrower
                 ----------------------------
hereby agrees to indemnify, hold harmless and defend (by counsel reasonably
satisfactory to the Administrative Agent) the Administrative Agent and each of
the Banks (and any successor to a Bank) and their respective directors,
officers, employees and agents from and against any and all claims, losses,
damages, liabilities, fines, penalties, charges, administrative and judicial
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,
in, under or about any Real Property of any Hazardous Materials, or any releases
or discharges of any Hazardous Materials on, under or from any Real Property and
(ii) any activity carried on or undertaken on or off any Real Property by
Borrower its Subsidiaries or any of their predecessors in title, whether prior
to or during the term of this Agreement, and whether by Borrower, its
Subsidiaries or any predecessor in title or any employees, agents, contractors
or subcontractors of Borrower, its Subsidiaries or any predecessor in title, or
any third persons at any time occupying or present on any Real Property (other
                                                                         -----
than a Bank or a representative of a Bank), in connection with the handling,
----
treatment, removal, storage, decontamination, clean-up, transport or disposal of
any Hazardous Materials at any time located or present on, in, under or about
any Real Property; provided that, anything to the contrary herein
                   --------
notwithstanding (including Exhibit J), the liability of Detroit shall be limited
to that portion of the Obligations which are used, directly or indirectly, to
finance the design, development, construction or operation of the Detroit
Project or which are actually borrowed or received by Detroit.  The foregoing
indemnity shall further apply to any residual contamination on, in, under or
about any Real Property, or affecting any natural resources, and to any
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, the expiration or termination of all
Letters of Credit and the payment and performance of all other Obligations owed
to the Banks.

          11.23  Gaming Boards.  The Administrative Agent and each of the
                 -------------
Banks agree to cooperate with all Gaming Boards in connection with the
administration of their regulatory jurisdiction over Borrower and its
Subsidiaries, including the provision of such documents or other information as
              ---------
may be requested by any such Gaming Board relating to Borrower or any of its
Subsidiaries or to the Loan Documents.

          11.24  Lien Releases.  The Administrative Agent shall release any

Obligations (i) sold, transferred or otherwise disposed of in connection with
any transaction not prohibited by the Loan Documents, (ii) constituting Property
leased to Borrower or its Subsidiaries under a lease which has expired or been
terminated in a transaction not prohibited by the Loan Documents or which will
concurrently expire and which has not been, and is not intended by Borrower or
the relevant Subsidiary to be, renewed or extended, (iii) consisting of an
instrument, if the Indebtedness evidenced by such instrument has been finally
repaid in full, (iv) if approved or consented to by those of the Banks required
by Section 11.2, or (v) as otherwise expressly required by the Loan Documents.
If the collateral so released consists of capital stock of a Subsidiary, then
the Administrative Agent shall concurrently also release such Subsidiary from
its obligations under the Guaranty.  Upon the request of the Administrative
Agent, each Bank shall promptly provide written confirmation of the authority of
the Administrative Agent to release such Liens upon any one or more items of
collateral under this Section.

          11.25  Termination; Release of Liens.  In addition to any Collateral

execute and deliver to Borrower and the Co-Borrowers discharges from further
compliance with the covenants contained in Articles 5, 6, and 7 and releases of
the Liens created by the Loan Documents, and shall return any Property pledged
to the Administrative Agent as collateral for the Obligations, notwithstanding
the survival of any provisions of this Agreement herein provided for.

          11.26  Nevada Gaming Collateral.  If any Collateral Event occurs, the
                 ------------------------
Administrative Agent shall, to the extent required by Gaming Laws, retain
possession of all pledged collateral consisting of the capital stock of (a)
Nevada gaming licensees within the State of Nevada at a location designated to
the Nevada State Gaming Control Board, and (b) gaming licensees in other

          designated by Borrower and the Co-Borrowers (and acceptable to the
          Administrative Agent, which acceptance shall not be unreasonably
          delayed or withheld), subject to (i) payment of a purchase price by
          such

                                      -96-

          to Section 2.8 (and, for this purpose, the numerical requirements of
          such Section shall not apply) by an amount equal to that Bank's Pro
          Rata Share, pay and provide to such Bank the amounts, assurances and
          indemnities described in subclauses (i) and (ii) of clause (x) above
          and release such Bank from its Pro Rata Share.

          11.28  Joint and Several.  Borrower and each of the Co-Borrowers shall
                 -----------------
be obligated for all of the Obligations on a joint and several basis,
notwithstanding which of them may have directly received the proceeds of any
particular Loan or Advance or the benefit of a particular Letter of Credit,

provided that, anything to the contrary herein notwithstanding (including
--------
Exhibit J), the liability of Detroit shall be limited to that portion of the
Obligations which are used, directly or indirectly, to finance the design,
development, construction or operation of the Detroit Project or which are
actually borrowed or received by Detroit.  Borrower and each of the Co-Borrowers
acknowledge and agree that, for purposes of the Loan Documents, Borrower, the
Co-Borrowers and the Guarantors constitute a single integrated financial
enterprise and that each receives a benefit from the availability of credit
under this Agreement.  Borrower and the Co-Borrowers each waive all defenses
arising under the Laws of suretyship, to the extent such Laws are applicable, in
connection with their joint and several obligations under this Agreement.
Without limiting the foregoing, Borrower and each of the Co-Borrowers agree to
the Joint Borrower Provisions set forth in Exhibit J, incorporated by this

in the event (i) there is any alleged breach or default by any Party under this
Agreement or any such Loan Document, or (ii) any party hereto has any claim
arising from or relating to any such Loan Document, no party hereto, nor any
party claiming through it (to the extent permitted by applicable Law), shall
commence any proceedings or otherwise seek to impose any liability whatsoever
against Mr. Kerkorian or Tracinda Corporation by reason of such alleged breach,
default or claim.

          11.30  Waiver of Right to Trial by Jury.  EACH PARTY TO THIS
                 --------------------------------
AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTY HERETO OR
ANY OF THEM WITH RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED
THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER
