                           STOCK PURCHASE AGREEMENT

      This Stock Purchase Agreement (this "Agreement") is made as of August 22,
1996 by and among Bally Entertainment Corporation, a Delaware corporation
("Buyer"), Bally's Grand, Inc., a Delaware corporation ("BGI"), and Bally's
Grand Property Sub I, Inc., a Nevada corporation ("Seller").

      Seller desires to sell to Buyer, and Buyer desires to purchase from
Seller, all of the issued and outstanding shares of capital stock (the "Shares")
of Paris Casino Corp., a Nevada corporation ("Subsidiary"), for the
consideration and on the terms set forth in this Agreement.

      Accordingly, in consideration of the foregoing and the mutual covenants
and undertakings contained herein, the parties hereby agree as follows:

1.    SALE AND TRANSFER OF SHARES; CLOSING.

      1.1   SHARES. Subject to the terms and conditions of this Agreement, at
the Closing, Seller shall sell to Buyer, and Buyer shall purchase from Seller,
the Shares.

      1.2   PURCHASE PRICE.

      (a) Subject to adjustment or substitution as provided below, the purchase
price (the "Purchase Price") for the Shares will be $57,500,000. The Purchase
Price will be payable to Seller at Closing as follows: (i) $17,500,000 payable
by wire transfer (in accordance with wire transfer instructions delivered by
Seller to Buyer at or prior to Closing) of immediately available funds and (ii)
that number of shares of common stock of Buyer ("Buyer Shares") equal to $40
million divided by the Effective Time Value (which the parties agree constitutes
1,457,195 Buyer Shares).

      (b) If, subsequent to Closing and at any time prior to the consummation of
the repurchase of Buyer Shares from Seller as set forth in Section 1.2(d)
hereof, the H Merger is terminated for any reason and Seller has not sold all of
the Buyer Shares prior to the announcement of such termination (any unsold Buyer
Shares as of the Determination Date being referred to herein as the "Unsold
Shares"), Buyer shall pay to Seller an amount equal to the difference, if any,
of (i) the product of the Effective Time Value and the number of the Unsold
Shares and (ii) the product of the average trading price (the "Termination
Average Price") of Buyer Shares on The New York Stock Exchange for the twenty
(20) trading days commencing after the date of public announcement of the
termination of the H Merger (the close of trading on such 20th trading day being
the "Determination Date") and the number of Unsold Shares (such difference, if
any, of (i) and (ii) being the "Owed Amount"). The Owed Amount shall be paid in
cash to Seller by wire transfer of immediately available funds within two (2)
days of the Determination Date. Notwithstanding the foregoing, in the event that
Buyer's repurchase obligation set forth in Section 1.2(d) hereof occurs any time
prior to payment of the Owed Amount, Buyer shall have no obligation to pay
Seller the Owed Amount.

<PAGE>
      (c) Seller agrees to provide written notice to Buyer (each such notice, a
"Sales Notice") on each business day during the Unregistered Period (as defined
below) that Seller intended to sell some or all of the unregistered Buyer Shares
(the "Intended Sale Date"). Each Sales Notice shall state (i) the number of
unregistered Buyer Shares Seller intended to sell on the Intended Sale Date,
(ii) the price at which Seller has been advised by a specialist on the New York
Stock Exchange (the "Specialist") in the common stock of Buyer that such a
number of Buyer Shares could be sold as of the Intended Sale Date (the
"Hypothetical Sale Price") and (iii) a covenant by Seller stating that Seller
shall sell such number of Buyer Shares as is set forth on such Sales Notice as
soon as practicable following receipt of notice delivered by Buyer to Seller as
to the registration of such Buyer Shares pursuant to Section 8 below (each such
date of sale of such Buyer Shares being an "Actual Sales Date," the gross sales
price paid to Seller on such Actual Sale Date being an "Actual Sales Price," and
the date of disposition of all Buyer Shares set forth on each Sales Notice
delivered to Buyer being the "Final Actual Sale Date"). Such Sales Notice shall
include, or promptly be followed by, a written confirmation of the Specialist as
to the Hypothetical Sale Price. Seller further agrees to provide prompt written
notice to Buyer as of the Final Actual Sale Date, of the number of shares sold
and the Actual Sales Price received as of each Actual Sales Date. In the event
that (A) such Buyer Shares as set forth on any Sales Notice are not registered
and freely transferrable on the applicable Intended Sale Date during the period
commencing on the Closing Date and ending on the earlier to occur of (i) the
Repurchase Date or (ii) the Effective Merger Date (such period referred to
herein as the "Unregistered Period"); and (B) Seller has substantially complied
with the requirements with respect to the delivery of Sales Notices as set forth
herein, then, within five (5) days of the Final Actual Sales Date, Buyer shall
pay to Seller the difference, if any, in immediately available funds between (x)
the product of the weighted average of the Hypothetical Sales Prices and the
total number of Buyer Shares sold by Seller on each Actual Sales Date and (y)
the product of the weighted average of the Actual Sales Prices and the total
number of Buyer Shares sold by Seller on each Actual Sales Date.

      (d) In the event that (i) Buyer fails to register the Buyer Shares
pursuant to Section 8 below within sixty (60) days subsequent to the Closing
Date (the "Repurchase Date"), and (ii) the Effective Merger Date has not
occurred prior to the consummation of the repurchase of Buyer Shares as set
forth in this Section 1.2(d), Buyer shall repurchase from Seller, no later than
five (5) days subsequent to the Repurchase Date and Seller shall sell to Buyer,
the Buyer Shares held by Seller as of the close of trading on the Repurchase
Date. The purchase price for the repurchased Buyer Shares shall be the product
of the Effective Time Value and the number of Buyer Shares held by Seller as of
the close of trading on the Repurchase Date, less the Owed Amount actually paid
to Seller, if any, payable by wire transfer of immediately available funds.

      (e) Buyer shall pay, in addition to the Purchase Price, the following
consideration: (i) upon demand in cash payable to Seller by wire transfer of
immediately available funds, the Development Costs; (ii) upon demand in cash
payable to Seller by wire transfer of immediately available funds, any sales,
stamp, transfer, recording or other like fees or taxes (the "Other Costs")
incurred by Seller and Subsidiary in connection with the purchase and sale of
the Shares and the transfer by Seller to Subsidiary of the Assets; and (iii)
upon demand in cash by wire transfer of immediately available funds any other
out-of-pocket costs and expenses (including attorney's fees and other advisory
fees) incurred in connection with the Contemplated

                                     -2-

Transactions (exclusive of attorney's fee and other advisory fees incurred in
connection with the preparation and execution of the Letter of Intent dated
August 14, 1996 and this Agreement) upto an aggregate of $1,000,000 (this

may have to Seller pursuant to Section 9 hereof).

Agreement will take place at the offices of Buyer, 8700 West Bryn Mawr Avenue,

9.    INDEMNIFICATION

      (a)   INDEMNIFICATION BY BUYER. Buyer agrees to indemnify and hold
harmless Seller, its directors, officers, employees, advisors and agents, to the
extent permitted by law, from and against any and all losses, claims, damages,
expenses (including, without limitation, reasonable costs of investigation and
fees, disbursements and other charges of counsel) or other liabilities resulting
from or arising out of or based upon any untrue, or alleged untrue, statement of
a material fact contained in such registration statement prepared pursuant to
Section 8 hereof (as amended or supplemented if Buyer shall have furnished any
amendments or supplements thereto) or arising out of or based upon any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, except
insofar as the same are caused by or contained in any information furnished in
writing to Buyer by Seller expressly for use therein; and provided, further,
that the Buyer shall not be liable in any such case to the extent that any such
loss, claim, damage, liability or expense arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, if such untrue statement or omission is
corrected in all material respects in an amendment or supplement to such
registration statement and the Seller thereafter fails to deliver the
registration statement as so amended or supplemented prior to or concurrently
with the sale of Buyer Shares to the Person asserting such loss, claim, damage,
liability or expense after the Buyer had furnished Seller with a sufficient
number of copies of the same.

      (b)   INDEMNIFICATION BY SELLER. In connection with the registration
statement prepared pursuant to Section 8 hereof in which Seller shall furnish to
Buyer in writing such information with respect to Seller as Buyer may reasonably
request or as may be required by law for use in connection with any registration
statement or prospectus to be used in connection with such registration and
Seller agrees to indemnify and hold harmless Buyer, any underwriter retained by
Buyer and their respective directors, officers, employees to the same extent as
the foregoing indemnity from Buyer to Seller (subject to the proviso to this
sentence and applicable law), but only with respect to any such information
furnished in writing by Seller expressly for use therein; provided, however,
that the liability of Seller under this Section 8(b) shall be limited to the
amount of the net proceeds received by Seller in the offering giving rise to
such liability.

      (c)   CONDUCT OF INDEMNIFICATION. Any Person entitled to indemnification
hereunder (the "Indemnified Party") agrees to give prompt written notice to the
indemnifying party (the "Indemnifying Party") after the receipt by the
Indemnified Party of any written notice of the commencement of any action, suit,
proceeding or investigation or threat thereof made in writing for which the
Indemnified Party intends to claim indemnification or contribution pursuant to
this Agreement; provided, however, the failure so to notify the Indemnifying
Party shall not relieve the Indemnifying Party of any liability that it may have
to the Indemnified Party hereunder. If notice of commencement of any such action
is given to the Indemnifying Party as above provided, the Indemnifying Party
shall be entitled to participate in and, to the extent it may wish, jointly with
any other Indemnifying Party similarly notified, to assume the defense

                                     -7-

<PAGE>
of such action at its own expense, with counsel chosen by it and satisfactory to
such Indemnified Party. The Indemnified Party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel (other than reasonable costs of
investigation) shall be paid by the Indemnified Party unless (i) the
Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party fails to
assume the defense of such action with counsel satisfactory to the Indemnified
Party in its reasonable judgment, (iii) the named parties to any such action
(including any impleaded parties) have been advised by such counsel that either
(A) representation of such Indemnified Party and the Indemnifying Party by the
same counsel would be inappropriate under applicable standards of professional
conduct or (B) there may be one or more legal defenses available to it which are
different from or additional to those available to the Indemnifying Party. In
either of such cases the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of such Indemnified Party. No Indemnifying
Party shall be liable for any settlement entered into without its written
consent, which consent shall not be unreasonably withheld. The rights accorded
to any Indemnified Party hereunder shall be in addition to any rights that such
Indemnified Party may have at common law, by separate agreement or otherwise.

      (d)   CONTRIBUTION. If the indemnification provided for in Section 9(a)
from the Indemnifying Party is unavailable to an Indemnified Party in respect of
any losses, claims, damages, expenses or other liabilities referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party,
shall contribute to the amount paid or payable by such Indemnified Party as a
result of such losses, claims, damages, expenses or other liabilities in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and Indemnified Party in connection with the actions which resulted in
such losses, claims, damages, expenses or other liabilities, as well as any
other relevant equitable considerations. The relative faults of such
Indemnifying Party and Indemnified Party shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact, was made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the Indemnifying Party's and
Indemnified Party's relative intent, knowledge, access to information and
opportunity to correct or prevent such action. The amount paid or payable by a
party as a result of the losses, claims, damages, expenses or other liabilities
referred to above shall be deemed to include, subject to the limitations set
forth in Sections 8(a), 8(b) and 8(c), any legal or other fees, charges or
expenses reasonably incurred by such party in connection with any investigation
or proceeding.
