Surviving Corporation.

       (b)     Cancellation of Treasury Stock and Gaming Co. Owned Stock. All 
shares of Company Common Stock that are owned by Company or any wholly-owned
Subsidiary of Company (but not any Employee Benefit Plans of Company or any of
its Subsidiaries) and any shares of Company Common Stock owned by Gaming Co. or
any wholly-owned Subsidiary of Gaming Co. shall be canceled and retired and
shall cease to exist and no stock of Company or any other consideration shall be
delivered in exchange therefor.

       (c)     Conversion of Company Stock.

           (i) Subject to Section 3.2(e), each issued and outstanding share of
Company Common Stock (other than shares to be canceled in accordance with

Stock equal to the Company Valuation Factor divided by the Gaming Co. Valuation
Factor, rounded to the fourth decimal (the "Exchange Ratio").

               (A)  For purposes of the foregoing, the "Company Valuation 
Factor" shall be equal to (1) $1,200,000,000 minus the dollar amount of the

Outstanding; provided, however, that if the Company Net Equity Value is less
than $617,600,000 but more than $585,100,000, then it shall be deemed to be
equal to $617,600,000; and provided, further, however, that if the Company Net
Equity Value is less than $585,100,000, then Hilton shall be entitled to
terminate this Agreement pursuant to Section 9.1(i).

                    (1)  For purposes of the foregoing, the "Total Debt of
Company" shall be (x) determined as of the earlier of (i) the Closing Date and
(ii) December 31, 1998 (the earlier of such dates, the "Determination Date") and
(y) equal to the total indebtedness for borrowed money (both long-term and
current maturities) of Company and its Subsidiaries as of the Determination

(excluding (i) maturities of long-term indebtedness, (ii) payables relating to

relating to unfunded expenditures under the Company Capital Plan, (iii) amounts
accrued for performance bonuses (but including amounts accrued for retention and
relocation bonuses) and (iv) liabilities that constitute Transaction Costs) of
Company and its Subsidiaries on a pro forma basis at December 28, 1997, plus the
total amount of 1998 capital expenditures under the Company Capital Plan that
remain unfunded as of the Determination Date (excluding up to $25 million in
Lady Luck-Biloxi acquisition and improvement costs and any additional capital
expenditures approved in writing by Hilton pursuant to Section 6.1), plus that
percentage of the total Transaction Costs that is equal to Company's
shareholders' pro forma ownership of Gaming Co. determined pursuant to the
foregoing formula as of the Determination Date but without giving effect to the
aggregate Transaction Costs, less (i) the total amount of Unrestricted Cash of
Company and its Subsidiaries as of the Determination Date, (ii) $8 million and
(iii) so long as Company has not consummated any sale, transfer or other
disposition involving its Gulfport headquarters prior to the Determination Date,

its Subsidiaries shall be as set on a "Company Closing Schedule" to be prepared
and finally determined as set forth in clause (2) below.

                    (2)  No later than the 10th business day before the day that
Company and Hilton reasonably estimate to be the Closing Date, Company shall
deliver the Company Closing Schedule to Hilton, together with all supporting
documentation reasonably necessary to Hilton's review and verification of the
Company Closing Schedule. The Company Closing Schedule shall set forth all of
the elements of the Total Debt of Company, as set forth in clause (1) above. In
the event the Determination Date is prior to December 31, 1998, the elements of
the Total Debt of Company set forth on the Company Closing Schedule shall
reflect Company's best estimates of the applicable amounts as of the Closing
Date, based on actual amounts as of the most recent month-end for which a
Company balance sheet is available (but in no event shall such balance sheet be
as of a date more than 60 days prior to the Closing Date), rolled forward to the
Closing Date based on reasonable assumptions and methodologies; and the details
of such assumptions and roll-forward methodologies shall be clearly stated in
the supporting materials delivered to Hilton. In the event that the
Determination Date is December 31, 1998, then the Company Closing Schedule shall
to the greatest extent possible reflect the actual amounts as of such date and
shall utilize estimates only to the extent necessary under the circumstances. In
each case, the elements of the Total Debt of Company shall be (i) set 


                                     - 17 -

forth in accordance with generally accepted accounting principles, applied on a
basis consistent with that used by Company in preparing the Company Retained
Business Balance Sheet and (ii) pro forma for the Company Distribution (i.e.,
shall reflect the elements of the Total Debt of Company as if the Company
Distribution had already occurred). The Company Closing Schedule shall be
accompanied by a certification of Company's chief financial officer that the
Company Closing Schedule has been prepared in accordance with the requirements
of this Section 3.1(c)(i)(A)(2). Unless Hilton, within five business days after
receipt of such schedule, notifies Company that it objects to any elements of
the Company Closing Schedule, specifying the basis for any such objection, the
amounts set forth on such schedule shall be binding upon the parties hereto for
purposes of calculating the Exchange Ratio. If Hilton does make an objection in
the manner specified above, then Company and Hilton shall use all reasonable
efforts to resolve such objection as promptly as possible. If Company and Hilton
are unable to resolve such objections within two business days after such
notification has been given by Hilton, the controversy shall be referred to the
Manhattan, New York office of Arthur Andersen LLP (or another nationally
recognized accounting firm reasonably acceptable to the parties hereto) for a
final determination thereof, which determination shall be made as promptly as
practicable. Such determination shall be binding upon the parties hereto for
purposes of calculating the Exchange Ratio, absent manifest error.

                    (3)  Upon delivery of the Company Closing Schedule, Company
shall provide to Hilton and its representatives such access to records,
workpapers and other documents, and to the personnel involved in preparation of
the Company Closing Schedule, as Hilton shall reasonably request for purposes of
reviewing and verifying the Company Closing Schedule.

                    (4)  For purposes of the foregoing, the "Total Number of
Company Shares Outstanding" is equal to 42,293,145, plus any additional shares
of Company Common Stock issued in accordance with the terms of Section 6.1 after
the date hereof and prior to the Effective Time (excluding any such issuances
relating to exercises or conversions of Company Stock Options (as defined in
Section 4.3)).

               (B)  Subject to the last paragraph of Section 6.2, for purposes 
of the foregoing, the "Gaming Co. Valuation Factor" shall be equal to (1)
$6,024,600,000 minus the dollar amount of the Total Debt of Gaming Co., divided
by (2) the Total Number of Gaming Co. Shares Outstanding.

                    (1)  For purposes of the foregoing, the "Total Debt of 
Gaming Co." shall be (x) determined as of the Determination Date and (y) equal
to the total indebtedness for borrowed money (both long-term and current
maturities) of Gaming Co. and its Subsidiaries as of the Determination Date,
plus the increase (if any) between (A) total current liabilities (excluding (i)
maturities of long-term indebtedness, (ii) payables relating to unfunded
expenditures relating to Gaming Co.'s Paris Casino-Resort, (iii) amounts accrued
for performance bonuses (but including amounts accrued for retention and
relocation bonuses) and (iv) liabilities that constitute Transaction Costs) of

Co.'s Paris Casino-Resort, (iii) amounts accrued for performance bonuses (but
including amounts accrued for retention and relocation bonuses) and (iv)
liabilities that constitute Transaction Costs) of Gaming Co. and its
Subsidiaries on a pro forma basis at December 31, 1997, plus the total amount of
capital expenditures that remain unfunded with respect to Gaming Co.'s Paris
Casino-Resort as of the Determination Date (excluding any additional capital
expenditures approved in writing by Company), plus that percentage of the total
Transaction Costs that is equal to 100% minus that percentage that is equal to
Company's shareholders' pro forma ownership of Gaming Co. determined pursuant to
the foregoing formula as of the Determination Date but without giving effect to
the aggregate Transaction Costs, less the total amount of Unrestricted Cash of
Gaming Co. and its Subsidiaries as of the Determination Date. The elements of
the Total Debt of Gaming Co. and its Subsidiaries shall be as set on a "Gaming
Co. Closing Schedule" to be prepared and finally determined as set forth in
clause (2) below.

                    (2)  No later than the 10th business day before the day that
Company and Hilton reasonably estimate to be the Closing Date, Hilton shall
deliver the Gaming Co. Closing Schedule to Company, together with all supporting
documentation reasonably necessary to Company's review and verification of the
Gaming Co. Closing Schedule. The Gaming Co. Closing Schedule shall set forth all
of the elements of the Total Debt of Gaming Co., as set forth in clause (1)
above. In the event the Determination Date is prior to December 31, 1998, the
elements of the Total Debt of Gaming Co. set forth on the Gaming Co. Closing
Schedule shall reflect Gaming Co.'s best estimates of the applicable amounts as
of the Closing Date, based on actual amounts as of the most recent month-end for
which a Gaming Co. balance sheet is available (but in no event shall such
balance sheet be as of a date more than 60 days prior to the Closing Date),
rolled forward to the Closing Date based on reasonable assumptions and
methodologies; and the details of such assumptions and roll-forward
methodologies shall be clearly stated in the supporting materials delivered to
Company. In the event that the Determination Date is December 31, 1998, then the
Gaming Co. Closing Schedule shall to the greatest extent possible reflect the
actual amounts as of such date and shall utilize estimates only to the extent
necessary under the circumstances. In each case, the elements of the Total Debt
of Gaming Co. shall be (i) set forth in accordance with generally accepted
accounting principles, applied on a basis consistent with those used by Hilton
in preparing the Gaming Co. Business Balance Sheet and (ii) pro forma for the
Hilton Distribution (i.e., shall reflect the elements of the Total Debt of
Gaming Co. as if the Hilton Distribution had already occurred). The Gaming Co.
Closing Schedule shall be accompanied by a certification of Gaming Co.'s chief
financial officer that the Gaming Co. Closing Schedule has been prepared in
accordance with the requirements of this Section 3.1(c)(i)(B)(2). Unless
Company, within five business days after receipt of such schedule, notifies
Hilton that it objects to any elements of the Gaming Co. Closing Schedule,
specifying the basis for any such objection, the amounts set forth on such
schedule shall be binding upon the parties hereto for purposes of calculating
the Exchange Ratio. If Company does make an objection in the manner specified
above, then Hilton and Company shall use all reasonable efforts to resolve such
objection as promptly as possible. If Hilton and Company are unable to resolve
such objections within two business days after such notification has been given
by Company, the controversy shall be referred to the Manhattan, New York office
of Arthur Andersen LLP (or another nationally recognized accounting firm
reasonably acceptable to the 

                                     - 19 -

parties hereto) for a final determination thereof, which determination shall be
made as promptly as practicable. Such determination shall be binding upon the
parties hereto for purposes of calculating the Exchange Ratio, absent manifest
error.

                    (3)  Upon delivery of the Gaming Co. Closing Schedule, 
Hilton shall provide to Company and its representatives such access to records,
workpapers and other documents, and to the personnel involved in preparation of
the Gaming Co. Closing Schedule, as Company shall reasonably request for
purposes of reviewing and verifying the Gaming Co. Closing Schedule.

                    (4)  For purposes of the foregoing, the "Total Number of
Gaming Co. Shares Outstanding" is equal to 260,450,202, plus any additional
shares of Gaming Co. Common Stock issued in accordance with the terms of Section
6.2 after the date hereof and prior to the Effective Time (excluding any such
issuances relating to exercises or conversions of Hilton Preferred Stock or
Hilton Stock Options (as defined in Section 5.3) or Gaming Co. options in
substitution thereof, and excluding any such issuances pursuant to the Employee
Stock Purchase Plan.

           (ii)    If, between the date of this Agreement and the Effective 
Time, the outstanding shares of Company Common Stock or Gaming Co. Common Stock
shall have been changed into a different number of shares or a different
class, by reason of any stock dividend, subdivision, reclassification,
recapitalization, split, combination or exchange of shares, or in the event
that Gaming Co. shares are distributed to Hilton Stockholders in the Hilton
Distribution on less than a 1 for 1 basis (a "non-equal distribution"), the
Exchange Ratio correspondingly shall be appropriately adjusted to reflect such
stock dividend, subdivision, reclassification, recapitalization, split,
combination, exchange of shares or non-equal distribution.

           (iii)   All such shares of Company Common Stock, when so converted,
shall no longer be outstanding and shall automatically be canceled and retired
and shall cease to exist, and each holder of a certificate representing any such
shares shall cease to have any rights with respect thereto, except the right to
receive the shares of Gaming Co. Common Stock and any cash in lieu of fractional
shares of Gaming Co. Common Stock to be issued or paid in consideration therefor
upon the surrender of such certificate in accordance with Section 3.2, and any
dividends or other distributions to which such holder is entitled pursuant to
Section 3.2(c), in each case without interest.

           (iv)    Pursuant to the Gaming Co. Rights Agreement, one Gaming Co.
Right will be attached to each share of Gaming Co. Common Stock issued upon
conversion of Company Common Stock in accordance with this Section 3.1(c) and
all references in this Agreement to Gaming Co. Common Stock shall be deemed to
include the Gaming Co. Rights.

    Section 3.2.    Exchange of Certificates. The  procedures  for  exchanging 
shares of Company Common Stock for Gaming Co. Common Stock pursuant to
the Merger are as follows:

       (a)     Exchange Agent. As of the Effective Time, Gaming Co. shall 
deposit with a bank or trust company designated by it and reasonably acceptable
to Company (the "Exchange 

                                     - 20 -

<PAGE>   26


Agent"), for the benefit of the holders of shares of Company Common Stock
outstanding immediately prior to the Effective Time, for exchange in accordance
with this Section 3.2, through the Exchange Agent, certificates representing the
shares of Gaming Co. Common Stock issuable pursuant to Section 3.1 in exchange
for outstanding shares of Company Common Stock (such shares of Gaming Co. Common
Stock, together with any dividends or distributions with respect thereto, being
hereinafter referred to as the "Exchange Fund").

       (b)     Exchange Procedures. As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock (the "Certificates"),
which shares were converted pursuant to Section 3.1 into the right to receive
shares of Gaming Co. Common Stock, (i) a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as Gaming Co. and
Company may reasonably specify) and (ii) instructions for effecting the
surrender of the Certificates in exchange for certificates representing shares
of Gaming Co. Common Stock (plus cash in lieu of fractional shares, if any, of
Gaming Co. Common Stock as provided below). Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by Gaming Co. and reasonably acceptable to Company, together with such
letter of transmittal, duly executed, the holder of such Certificate shall be
entitled to receive in exchange therefor a certificate representing that number
of whole shares of Gaming Co. Common Stock which such holder has the right to
receive pursuant to the provisions of this Article III, and the Certificate so
surrendered shall immediately be canceled. In the event of a transfer of
ownership of Company Common Stock prior to the Effective Time which is not
registered in the transfer records of Company, a certificate representing the
proper number of shares of Gaming Co. Common Stock may be issued to a transferee
if the Certificate representing such Company Common Stock is presented to the
Exchange Agent accompanied by all documents required to evidence and effect such
transfer and by evidence that any applicable stock transfer taxes have been
paid. After the Effective Time, each outstanding Certificate which theretofore
represented shares of Company Common Stock shall represent only the right to
receive shares of Gaming Co. Common Stock (and cash in lieu of fractional
shares, if any) pursuant to the terms hereof and shall not be deemed to evidence
ownership of the number of shares of Gaming Co. Common Stock into which such
shares of Company Common Stock were converted until the Certificate therefor
shall have been surrendered in accordance with this Section 3.2.

       (c)     Distributions With Respect to Unexchanged Shares. No dividends or
other distributions declared or made after the Effective Time with respect to
Gaming Co. Common Stock with a record date after the Effective Time shall be
paid to the holder of any unsurrendered Certificate with respect to the shares
of Gaming Co. Common Stock the holder thereof is entitled to receive in exchange
therefor and no cash payment in lieu of fractional shares shall be paid to any
such holder pursuant to subsection (e) below until the holder of record of such
Certificate surrenders such Certificate. Subject to the effect of Applicable
Laws, following surrender of any such Certificate there shall be paid to the
record holder of the certificates representing whole shares of Gaming Co. Common
Stock issued in exchange therefor, without interest, (i) at the 

                                     - 21 -
<PAGE>   27

time of such surrender, the amount of any cash payable in lieu of a fractional
share of Gaming Co. Common Stock to which such holder is entitled pursuant to
subsection (e) below and the amount of dividends or other distributions with a
record date after the Effective Time previously paid with respect to such whole
shares of Gaming Co. Common Stock and (ii) at the appropriate payment date, the
amount of dividends or other distributions with a record date after the
Effective Time but prior to surrender and a payment date subsequent to surrender
payable with respect to such whole shares of Gaming Co. Common Stock.

       (d)     No Further Ownership Rights in Company Common Stock. All shares 
of Gaming Co. Common Stock issued upon the surrender for exchange of
Certificates in accordance with the terms hereof (and any cash paid pursuant to
subsection (c) or (e) of this Section 3.2) shall be deemed to have been issued
in full satisfaction of all rights pertaining to the shares of Company Common
Stock theretofore represented by such Certificates, subject, however, to the
Surviving Corporation's obligation to pay any dividends or make any other
distributions with a record date prior to the Effective Time which may have been
declared or made by Company on such shares of Company Common Stock in accordance
with the terms of this Agreement (to the extent permitted under Section 6.1) or
prior to the date hereof and which remain unpaid at the time of such surrender;
and from and after the Effective Time there shall be no further registration of
transfers on the stock transfer books of the Surviving Corporation of the shares
of Company Common Stock which were outstanding immediately prior to the
Effective Time. If, after the Effective Time, Certificates are presented to the
Surviving Corporation or Gaming Co. for any reason, such Certificates shall be
canceled and exchanged as provided in this Section 3.2.

       (e)     No Fractional Shares. No certificate or scrip representing 
fractional shares of Gaming Co. Common Stock shall be issued upon the surrender
for exchange of Certificates, and such fractional share interests will not
entitle the owner thereof to vote or to any other rights of a stockholder of
Gaming Co. Notwithstanding any other provision of this Agreement, each holder of
shares of Company Common Stock outstanding immediately prior to the Effective
Time exchanged pursuant to the Merger who would otherwise have been entitled to
receive a fraction of a share of Gaming Co. Common Stock (after taking into
account all Certificates held by such holder) shall receive, in lieu thereof,
cash (without interest) in an amount equal to such fractional part of a share of
Gaming Co. Common Stock multiplied by the per share closing sales price of
Gaming Co. Common Stock (as reported on the New York Stock Exchange Composite
Tape) on the first day of trading of Gaming Co. Common Stock on the NYSE after
the Effective Time.

       (f)     Termination of Exchange Fund. Any portion of the Exchange Fund 
which remains undistributed to the shareholders of Company for 180 days after
the Effective Time shall be delivered to Gaming Co. upon demand, and any
shareholder of Company who has not previously complied with this Section 3.2
shall thereafter look only to Gaming Co. for payment of such shareholder's claim
for Gaming Co. Common Stock, any cash in lieu of fractional shares of Gaming Co.
Common Stock and any dividends or distributions with respect to Gaming Co.
Common Stock.

       (g)     No Liability. Neither Hilton, Gaming Co. nor Company shall be 
liable to any holder of shares of Company Common Stock for any shares of Gaming
Co. Common Stock (or 

                                     - 22 -

<PAGE>   28


dividends or distributions with respect thereto) or cash in lieu of fractional
shares delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.

       (h)     Withholding Rights. Gaming Co. and the Surviving Corporation 
shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of shares of Company Common
Stock such amounts as it is required to deduct and withhold with respect to such
consideration under the Code or any provision of federal, state, local or
foreign tax law. To the extent that amounts are so withheld by Gaming Co. or the
Surviving Corporation, such withheld amounts shall be treated for all purposes
of this Agreement as having been paid to the holder of the shares of Company
Common Stock in respect of which such deduction and withholding was made.

       (i)     Lost Certificates. If any Certificate shall have been lost, 
stolen or destroyed, upon the making of an affidavit of that fact by the Person
claiming such Certificate to be lost, stolen or destroyed and, if required by
Gaming Co. or the Surviving Corporation, the posting by such Person of a bond in
such reasonable amount as Gaming Co. or the Surviving Corporation may direct as
indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will issue in exchange for such lost, stolen or
destroyed Certificate the shares of Gaming Co. Common Stock and any cash in lieu
of fractional shares and unpaid dividends and distributions on shares of Gaming
Co. Common Stock deliverable in respect thereof pursuant to this Agreement.

       (j)     Affiliates. Notwithstanding anything herein to the contrary,
Certificates surrendered for exchange by any Affiliate of Company shall not be
exchanged until Gaming Co. has received an Affiliate Agreement from such
Affiliate.

       (k)     Dissenting Shares. Any shares of Common Stock held by a holder 
who dissents from the Merger and becomes entitled to obtain payment for the
value of such Common Stock pursuant to the applicable provisions of Minnesota
law shall be herein called "Dissenting Shares." Any Dissenting Shares shall not,
after the Effective Time, be entitled to vote for any purpose or receive any
dividends or other distributions and shall not be converted into Gaming Co.
Common Stock; provided, however, that the Common Stock held by a dissenting
shareholder who subsequently withdraws a demand for payment, fails to comply
fully with the requirements of Minnesota law, or otherwise fails to establish
the right of such shareholder to be paid the value of such shareholder's shares
under Minnesota law shall be deemed to be have been converted into Gaming Co.
Common Stock pursuant to the terms and conditions referred to above.


                                   ARTICLE IV.

                    REPRESENTATIONS AND WARRANTIES OF COMPANY

Each of Company and its Subsidiaries is duly qualified or licensed to do
business and is in good standing in each jurisdiction in which the nature of its
business or the ownership or leasing of its properties makes such qualifications

Material Adverse Effect with respect to Company or the Company Retained
Business. Company has made available to Hilton complete and correct copies of
its Articles of Incorporation and Company Bylaws and the comparable charter or
organizational documents of its Subsidiaries, in each case, as amended to the

    Section 4.2.    Subsidiaries. The Company Disclosure Schedule sets forth
all the Subsidiaries of Company and each other Person in which Company owns,

wholly-owned Subsidiary of Company, free and clear of any and all mortgages,
security interests, liens, claims, pledges, restrictions, leases, title
exceptions, rights of others, charges or other encumbrances ("Encumbrances").

incorporation and bylaws or other organizational documents of Company's
Subsidiaries do not contain any provision limiting or otherwise restricting the
ability of Gaming Co., following the Effective Time, from controlling such
Subsidiaries on the same basis as Company.

    Section 4.3.    Capitalization. The authorized capital stock of Company

of Company or the value of shares of Company Common Stock. All outstanding

contemplated by this Agreement will be, when issued, duly authorized, validly
issued, fully paid and nonassessable and not subject to preemptive rights. As of
the date of this Agreement, there are no bonds, debentures, notes or other
indebtedness of Company or any other Person having the right to vote (or

of its Subsidiaries or obligating Company or any of its Subsidiaries to issue,
grant, extend or enter into any such security, option, warrant, call, right,

Laws or similar provisions contained in the terms of the capital stock of
Company or any of its Subsidiaries, as of the date of this Agreement, there are
not any outstanding contractual obligations of Company or any of its

any obligation or cause loss of a material benefit under, or result in the

properties or assets of Company or any of its Subsidiaries under, (i) the
Articles of Incorporation or Company Bylaws or the comparable charter or
organizational documents of its Subsidiaries, (ii) any loan or credit agreement,

judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to Company or any of its Subsidiaries or their respective properties or assets,

violations, defaults, rights, liabilities or liens that would not, individually
or in the aggregate, (x) have a Material Adverse Effect with respect to Company
or the Company Retained Business, (y) impair, in any material respect, the
ability of Company or Lakes to perform its obligations under each of the
Transaction Documents to which it is a party or (z) prevent or significantly
delay the consummation of any of the transactions contemplated by the

state securities or "blue sky" laws and (vi) such other consents, approvals,
orders, authorizations, registrations, declarations and filings which, if not

applicable to "control share acquisitions" will not apply to the authorization,
execution, delivery and performance of this Agreement or each of the Transaction
Documents by Company to which it is a party or the consummation of the Merger by
Company. No other "fair price," "moratorium," or other similar anti-takeover
statute or regulation is applicable to Company or (by reason of Company's
participation therein) the Merger or the other transactions contemplated by this
Agreement or the other Transaction Documents to which it is a party.

       (a)     Each of Company and its Subsidiaries has in effect all Permits
necessary for it to own, lease or operate its properties and assets and to carry
on its business as now conducted, other than such Permits the absence of which
would not, individually or in the aggregate, have a Material Adverse Effect with
respect to Company or the Company Retained Business, and there has occurred no
default under any such Permit other than such defaults which, individually or in
the aggregate, would not have a Material Adverse Effect with respect to Company
or the Company Retained Business. Company and its Subsidiaries are in compliance

in the aggregate, would not have Material Adverse Effect with respect to Company
or the Company Retained Business.

entity formerly owned by Company or its Subsidiaries, while so owned, was in

such noncompliance which, individually or in the aggregate, would not have
Material Adverse Effect with respect to Company or the Company Retained
Business.

       (c)     During the period of ownership or operation by Company and its
Subsidiaries of any of their owned or leased properties, there has been no
Release of Hazardous Material in, on, under or affecting such properties and
none of Company or its Subsidiaries has disposed of any Hazardous Material or
any other substance in a manner that has led to, or could reasonably be
anticipated to lead to, a Release except in each case for those which are not,
individually or in the aggregate, reasonably likely to have a Material Adverse
Effect with respect to Company or the Company Retained Business.

    Section 4.7.    Company SEC Documents; Undisclosed Liabilities.

       (a)     Each of Company and its Subsidiaries has filed all required

requirements of the Securities Act or the Exchange Act, as applicable, and the
rules and regulations of the SEC promulgated thereunder applicable to such
Company SEC Documents and (ii) none of the Company SEC Documents contained at
the time they were filed or declared effective any untrue statement of a
material fact or omitted at the time they were filed or declared effective to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances in which they were
made, not misleading. At their respective dates, the financial statements of
Company included in the Company SEC Documents complied as to form in all
material respects with the applicable accounting requirements and with the
published rules and regulations of the SEC with respect thereto, were prepared
in accordance with generally accepted accounting principles ("GAAP") (except, in
the case of unaudited statements, as permitted by Form 10-Q of the SEC) applied
on a consistent basis during the periods involved (except as may be indicated in
the notes thereto) and fairly presented (subject, in the case of unaudited

financial position of Company and its consolidated Subsidiaries as of and at the
dates thereof and the consolidated results of their operations and cash flows
for the periods then ended.

       (b)     Except as disclosed in the Company SEC Documents filed and 
publicly available prior to the date of this Agreement and except for
liabilities and obligations incurred in the ordinary course of business

in the notes, exhibits or schedules thereto or (ii) which reasonably could be
expected to have a Material Adverse Effect

with respect to Company or the Company Retained Business. Except as set forth

any kind (whether accrued, absolute, contingent or otherwise) relating to the
Lakes Group or its assets, liabilities, operations or businesses (i) required by
GAAP to be reflected on a consolidated balance sheet of Lakes and its
consolidated Subsidiaries or in the notes, exhibits or schedules thereto
(assuming the Company Distribution had been effected) or (ii) which reasonably
could be expected to have a Material Adverse Effect with respect to Lakes or the
Lakes Business.

Company SEC Documents filed and publicly available prior to the date hereof, and
except for the Company Distribution and the other transactions contemplated by

       (a)     Company and each of its Subsidiaries, and each affiliated group
(within the meaning of Section 1504 of the Code) of which Company or any of its
Subsidiaries is or has ever been a member, has timely filed all federal income
Tax Returns and all other material Tax Returns required to be filed by them. All
such Tax Returns are complete and correct in all material respects. Company and
each of its Subsidiaries has paid (or Company has paid on its Subsidiaries'
behalf) all Taxes shown as due on such Tax Returns. The most recent consolidated
financial statements contained in Company SEC Documents reflect an adequate
reserve for all Taxes payable by Company and its Subsidiaries for all taxable

       (b)     No material deficiencies for any Taxes have been proposed, 
asserted or assessed against Company or any of its Subsidiaries that have not
been fully paid or adequately provided for in the appropriate financial
statements of Company and its Subsidiaries, no requests for waivers of the time
to assess any Taxes are pending, and none of Company or any of its Subsidiaries
has waived any statute of limitations in respect of Taxes or agreed to any
extension of time with respect to a Tax assessment or deficiency. There is no
dispute or claim concerning any material Tax Liability of any of Company and its
Subsidiaries either (i) claimed or raised by any authority in writing or (ii) as
to which any of the officers or employees responsible for Tax matters of any of
Company and its Subsidiaries has knowledge based upon personal contact with any
agent of such authority. The statute of limitations for the federal income Tax
Returns of Company and each of its Subsidiaries consolidated in such Tax Returns
have expired for all years through July 31, 1992.

       (c)     No material liens for Taxes exist with respect to any assets or
properties of Company or any of its Subsidiaries, except for statutory liens for
Taxes not yet due.

       (d)     Except as contemplated by the Company Distribution Agreement, 
none of Company or any of its Subsidiaries is a party to or is bound by any tax
sharing agreement, tax indemnity obligation or similar agreement, arrangement or

reorganization qualifying under the provisions of Section 368(a)(1)(B) of the
Code or (ii) the Company Distribution from 

                                     - 30 -

amount (whether in cash or property or the vesting of property) as a result of
any of the transactions contemplated by the Transaction Documents to any
employee, officer or director of Company or any of its affiliates who is a
"disqualified individual" (as such term is defined in proposed Treasury
Regulation Section 1.280G-1) that would be characterized as an "excess parachute
payment" (as such term is defined in Section 280G(b)(1) of the Code).

       (g)     Company and its Subsidiaries have complied in all material 
respects with all applicable laws, rules and regulations relating to the payment

       (h)     There are no federal, state, local or foreign audits or other
administrative proceedings or court proceedings presently pending with regard to
any federal or state, local or foreign Taxes or Tax Returns of Company or its
Subsidiaries and neither Company nor any of its Subsidiaries has received a
written notice of any pending audit or proceeding. To the Company's knowledge,
Company has settled the audit of its federal Tax Return relating to the
depreciation of its dockside casinos. The terms of such settlement are set forth
on the Company Disclosure Schedule (the "Settlement Agreement").

       (i)     Neither Company nor any of its Subsidiaries has agreed to or is
required to make any adjustments under Section 481(a) of the Code.

       (j)     Neither Company nor any of its Subsidiaries has, with regard to 
any assets or property held or acquired by any of them, filed a consent to the
application of Section 341(f) of the Code or agreed to have Section 341(f)(2) of
the Code apply to any disposition of a subsection (f) asset (as such term is

the Code) for any material excise tax or civil penalty and (vi) neither Company
nor any Subsidiary of Company has any liabilities or obligations with respect to
any Employee Benefit Plan, whether accrued, contingent or otherwise, except

Multiemployer Plan, suffered or otherwise caused a "complete withdrawal" or
"partial withdrawal," as such terms are respectively defined in Sections 4023
and 4025 of ERISA, which has resulted in any material liability to Company or

contemplated thereby will: (i) result in any material payment becoming due, or
materially increase the amount of compensation due, to any current or former
employee of Company or any of its Subsidiaries; (ii) materially increase any
benefits otherwise payable under any Employee Benefit Plan; or (iii) result in
the acceleration of the time of payment or vesting of any such material

Subsidiaries as lessee as of the date hereof (such owned and leased material
real property, including all Improvements thereon, referred to collectively as
the "Real Property"). The Real Property set forth on the Company Disclosure
Schedule comprises all of the material real property necessary and/or currently
used in the operations of the business of Company and its Subsidiaries. Company

designated as leased) a valid leasehold interest in, all of the Real Property.
The Real Property is free of Encumbrances, except for Permitted Encumbrances and
Encumbrances created under the First Mortgage Notes Indenture, and the

Company, no Contamination exists at, on or under the Real Property at levels
that contravene those allowed by Environmental Laws.

    Section 4.15.   Indian Gaming and Debt Agreements and Lakes Agreements.
The execution and delivery by each of Company and Lakes of this Agreement and
each of the Transaction Documents to which it is a party does not, and the
consummation of the transactions contemplated hereby and thereby will not,
conflict with, or result in any violation of, or default (with or without notice
of lapse of time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or cause loss of a material
benefit under, or result in the creation or maturation of any lien, liability or
purchase right upon any of the properties or assets of Company or any Subsidiary
under any of the Indian Gaming and Debt Agreements or the Lakes Agreements and
in each case, to which Company or any of its Affiliates or Subsidiaries is a
party or subject to, or to Company's knowledge, to which any other Person is a
party or subject to, or have or result in a Material Adverse Effect to Company
with respect to any of the Indian Gaming and Debt Agreements or Lakes Agreements

the other party in doing, all things necessary, proper or advisable to
consummate and make effective, in the most expeditious manner practicable, the
Merger and the other transactions contemplated by this Agreement, including (i)
the obtaining of all necessary action or nonactions, waivers, consents and
approvals from Governmental Authorities and the making of all necessary
registrations and filings (including filings with Governmental Authorities, if
any) and the taking of all steps as may be reasonably necessary to obtain an
approval or waiver from, or to avoid an action or proceeding by, any
Governmental Authority (including in respect of any Gaming Law), (ii) the
obtaining of all necessary consents, approvals or waivers from third parties,
(iii) the defending of any lawsuits or other legal proceedings, whether judicial
or administrative, challenging any of the Transaction Documents or the
consummation of any of the transactions contemplated thereby, including seeking
to have any stay or temporary restraining order entered by any court or other
Governmental Authority vacated or reversed and (iv) the execution and delivery
of any additional instruments necessary to consummate the transactions
contemplated by, and to fully carry out the purposes of, the Transaction
Documents.

    Section 7.5.   Approval of Gaming Commissions; Regulatory Matters. Hilton 
and Company shall as promptly as practicable, but in no event later than 30 days
following the execution and delivery of this Agreement, file or submit those
filings and other submissions under applicable Gaming Laws in connection with
the Transaction Documents and the transactions contemplated thereby, and to
respond as promptly as practicable in order to obtain as soon as practicable
those approvals and consents required or necessary in connection with the
Transaction Documents or the transactions contemplated thereby. In addition,
each of Hilton and Company shall, and shall cause each of its Subsidiaries to
(and shall use its reasonable efforts to cause each of its affiliates other than
each of its Subsidiaries to), if it is necessary to obtain any regulatory
approval for the Merger or the Distributions, disassociate themselves from any
Person or Persons deemed, or reasonably likely to be deemed, unsuitable by any
Gaming Commission. Hilton and Company shall keep each other apprised of the
status of any communications with, and any inquiries or requests for additional
information from, the Gaming Commissions and shall comply promptly with any such

    Section 7.6.   Supplemental Disclosure. Subject to compliance with 
applicable Gaming Laws, Company shall confer on a regular and frequent basis
with Hilton, report on operational matters and promptly notify Hilton of, and
furnish Hilton with, any information it may reasonably request with respect to,
any event or condition or the existence of any fact that could reasonably be
expected to cause any of the conditions to Hilton's obligation to consummate the
Merger and the Hilton Distribution not to be completed, and Hilton shall
promptly notify Company of, and furnish Company any information it may
reasonably request with respect to, any event or condition or the existence of
any fact that could reasonably be expected to cause any of the conditions to
Company's obligation to consummate the Merger and the Company Distribution not
to be completed.

    Section 7.7.   Announcements. Prior to the Closing, none of the parties 
hereto shall issue any press release or make any public announcement with
respect to this Agreement and the Merger without the prior consent of the other
(which consent shall not be unreasonably withheld), except as may be required by
Applicable Laws or applicable stock exchange regulations, in which event the
party required to make the release shall, if possible, allow the other party
reasonable time to comment on such release in advance of such issuance. The
parties hereto agree that the initial press release to be issued with respect to
the transactions contemplated hereby shall be in a form heretofore agreed to by
the parties hereto.

    Section 7.8.   No Solicitation.

         (a)       Company shall not, and shall not permit or cause any of its
Subsidiaries or any of the officers and directors of it or its Subsidiaries to,
and shall direct its and its Subsidiaries' employees, agents and representatives
(including any investment banker, attorney or accountant retained by it or any
of its Subsidiaries) not to, directly or indirectly, initiate, solicit, or
otherwise encourage any inquiries or the making of any proposal or offer with
respect to a merger, reorganization, share exchange, tender offer, consolidation
or similar transaction involving, or any purchase of, 15% or more of the assets
or any equity securities of Company or any of its Subsidiaries (any such
proposal or offer being hereinafter referred to as an "Acquisition Proposal").
Company shall not, and shall not permit or cause any of its Subsidiaries or any
of the officers and directors of it or its Subsidiaries to, and shall direct its
and its Subsidiaries' employees, agents and representatives (including any
investment banker, attorney or accountant retained by it or any of its
Subsidiaries) not to, directly or indirectly, engage in any negotiations
concerning, or provide any confidential information or data to, or have any
discussions with, any Person relating to an Acquisition Proposal, whether made
before or after the date of this Agreement, or otherwise facilitate any effort
or attempt to make or implement or consummate an Acquisition Proposal; provided,
however, that nothing contained in this Agreement shall prevent Company or its
Board of Directors from (i) complying with Rule 14e-2 promulgated under the
Exchange Act with regard to an Acquisition Proposal or (ii) at any time after
180 days from the date hereof if the Merger shall not by such date have received
the Company Shareholder Approval: (x) providing information in response to a
request therefor by a Person who has made an unsolicited bona fide written
Acquisition Proposal if the Board of Directors receives from the Person so
requesting such information an executed confidentiality agreement on terms
substantially equivalent to those contained in the Confidentiality Agreement;
(y) engaging in any 

                                      - 53 -
<PAGE>   59

negotiations or discussions with any Person who has made an unsolicited bona
fide written Acquisition Proposal; or (z) recommending such an Acquisition
Proposal to the shareholders of Company, if, and only to the extent that, (i) in
each such case referred to in clause (x), (y) or (z) above, the Board of
Directors of Company determines in good faith after consultation with outside
legal counsel that such action is necessary in order for its directors to comply
with their respective fiduciary duties under applicable law and (ii) in each
case referred to in clause (y) or (z) above, the Board of Directors of Company
determines in good faith (after consultation with its financial advisor) that
such Acquisition Proposal, if accepted, is reasonably likely to be consummated,
taking into account all legal, financial and regulatory aspects of the proposal
and the Person making the proposal, and would, if consummated, result in a more
favorable transaction than the transaction contemplated by this Agreement,
taking into account the long-term prospects and interests of Company and its
shareholders. Company shall immediately cease and cause to be terminated any
existing activities, discussions or negotiations with any parties conducted
heretofore with respect to any of the foregoing. Company agrees that it will
take the necessary steps to promptly inform the individuals or entities referred
to in the first sentence hereof of the obligations undertaken in this Section
7.8 and in the Confidentiality Agreement. Company also shall promptly request
each Person that has heretofore executed a confidentiality agreement in
connection with its consideration of an Acquisition Proposal to return all
confidential information heretofore furnished to such Person by or on behalf of
it or any of its Subsidiaries.

         (b)       Company shall notify Hilton immediately if any Acquisition 
Proposal or inquiries regarding a potential Acquisition Proposal are received
by, any information with respect to an Acquisition Proposal or a potential
Acquisition Proposal is requested from, or any discussions or negotiations with
respect to an Acquisition Proposal or a potential Acquisition Proposal are
sought to be initiated or continued with, it or any of its representatives
indicating, in connection with such notice, the name of the Person involved and
the material terms and conditions of any such Acquisition Proposal, and
thereafter shall keep Hilton informed, on a current basis, on the status and
terms of any such inquiries or Acquisition Proposals and the status of any such
negotiations or discussions. Nothing in this Section 7.8(b), however, shall be
construed as authorizing Company, its Subsidiaries or their respective
employees, agents or representatives to engage in any activities prohibited by
Section 7.8(a) hereof.

    Section 7.9.   Indemnification.

         (a)       All indemnification obligations existing as of the date 
hereof (including indemnification obligations relating to or arising out of the
transactions contemplated by this Agreement) relating to acts or omissions
occurring at or prior to the Effective Time in favor of the current or former
directors or officers of Company or any of its Subsidiaries (the "Indemnified
Persons") in the articles of incorporation or bylaws (or comparable
organizational documents) or indemnity contracts of Company or its Subsidiaries
(i) will be assumed by each of the Surviving Corporation and Lakes, each of whom
shall be jointly and severally liable for such indemnification, without further
action, as of the Effective Time and (ii) shall continue in full force and
effect in accordance with their respective terms for a period not less than six
years from the Effective Time. The parties hereto acknowledge and agree that
nothing in the preceding 

                                    - 54 -
<PAGE>   60

sentence modifies or in any way limits Company's ability or rights to seek
indemnification from Lakes pursuant to Section 7.9(b) with respect to any of the
foregoing obligations. If the Surviving Corporation is required to indemnify any
Indemnified Person for any act or omission relating to any of the
Non-Mississippi Group Liabilities (as defined in the Company Distribution
Agreement), including those relating to (A) Stratosphere, the Stratosphere
Litigation and/or the Stratosphere Contracts or (B) the Lakes Business,
including the Lakes Contracts and/or any member of the Lakes Group, then as a
condition to such indemnification, such Indemnified Person shall enter into a
subrogation agreement pursuant to which the Surviving Corporation shall be
subrogated to, and shall stand in the place of, such Indemnified Person as to
any events or circumstances in respect of which such Indemnified Person may have
any right or claim relating to such Non-Mississippi Group Liabilities against
any claimant or plaintiff asserting such liabilities against the Indemnified
Person, or against any other party (other than an Indemnified Person) that may
be liable.

         (b)       Lakes shall indemnify, defend and hold harmless the Surviving
Corporation and its Affiliates from and against any and all losses, liabilities,
damages and expenses (including the reasonable costs and expenses of
investigation and reasonable attorneys' fees and expenses in connection with any
or all such investigations or any and all Actions or threatened Actions)
incurred or suffered by the Surviving Corporation or any of its Affiliates
relating to the Non-Mississippi Group Liabilities, including those relating to
(A) the Stratosphere, the Stratosphere Litigation and/or the Stratosphere
Contracts and (B) the Lakes Business, including the Lakes Contracts and/or any
member of the Lakes Group.

         (c)       Prior to the Effective Time, Lakes and Company shall enter
into the Trust Agreement in the form of Exhibit M attached hereto (the "Trust
Agreement") and the Pledge and Security Agreement in the form of Exhibit N
attached hereto (the "Pledge and Security Agreement," and together with the
Trust Agreement, the "Security Agreements"), in each case, with such changes
thereto as the trustee thereunder may reasonably request, pursuant to which
Lakes shall deposit and make available the amounts set forth in such Security
Agreements for the time periods specified therein to secure and satisfy any and
all indemnification claims made or asserted against it pursuant to any of the
Transaction Documents.

         (d)       For so long as the Surviving Corporation is required to 
provide indemnification to any of the Indemnified Persons, Lakes shall not, and
shall not permit any of its Subsidiaries to, directly or indirectly, make any
Restricted Payment. If Lakes is unable, within 15 days of request, to pay in
full any claim made for indemnification by the Surviving Corporation or any of
its Affiliates pursuant to this Agreement or the Company Distribution Agreement,
then for so long as any such claim or any other claim for indemnification made
by the Surviving Corporation or any of its Affiliates remains unpaid, Lakes
shall not, and shall not permit any of its Subsidiaries to, directly or
indirectly, create, incur, issue, assume, guaranty or otherwise become directly
or indirectly liable with respect to any indebtedness.

         (e)       For so long as the Surviving Corporation is required to
provide indemnification to any Indemnified Person, Gaming Co.'s ability to
transfer any material Mississippi Group Assets (as defined in the Company
Distribution Agreement) out of the Surviving Corporation 

                                    - 55 -

<PAGE>   61

shall be limited as follows. In connection with the transfer of any material
Mississippi Group Asset out of the Surviving Corporation, Gaming Co. shall
determine the net equity value of such asset at the time of such transfer (i.e.,
the fair market value of such asset less any indebtedness and known liabilities
relating thereto). So long as the net equity value of the asset being
transferred, together with the aggregate net equity values of all assets
previously transferred, is equal to or less than the total indebtedness of
Company as of the Determination Date under the Indentures and the Revolving
Credit Facility (collectively, the "Threshold Debt"), the subject asset can be
transferred without restriction. If, however, the net equity value of the asset
being transferred, together with the aggregate net equity values of all assets
previously transferred, is more than the Threshold Debt (such excess being
referred to as the "Required Credit Support"), then Gaming Co. shall either (i)
contribute to the Surviving Corporation assets with a net equity value at least
equal to the Required Credit Support or (ii) guaranty the indemnification
obligations to the Indemnified Persons in an amount at least equal to the
Required Credit Support. Once Gaming Co. is required to provide any Required
Credit Support, it shall only be entitled to transfer additional material
Mississippi Group Assets out of the Surviving Corporation if it concurrently
with such transfer either (x) contributes to the Surviving Corporation other
assets with a net equity value at least equal to the net equity value of the
assets to be transferred out of the Surviving Corporation or (ii) guarantees the
indemnification obligations of the Surviving Corporation to the Indemnified
Persons in an amount at least equal to the net equity value of the assets to be
transferred out of the Surviving Corporation.

         (f)       The provisions of this Section 7.9 are intended to be for the
benefit of, and shall be enforceable by, the Surviving Corporation and each
Indemnified Person (including such Person's heirs and representatives) and shall
be binding on all successors and assigns of the Surviving Corporation, Gaming
Co. and Lakes.

    Section 7.10.  Distributions. 

         (a)       Prior to the Closing, Hilton will, and will cause each of its
Subsidiaries that is a party thereto, to enter into the Hilton Distribution
Agreement and such ancillary agreements (the "Hilton Ancillary Agreements") as
are reasonably required to effect the Hilton Distribution and to govern the
relationships between Hilton and Gaming Co. following the Hilton Distribution.
The Hilton Distribution Agreement and the Hilton Ancillary Agreements will
conform in all material respects to the terms of the subject forms attached
hereto as Exhibit A, with such changes thereto as Hilton and Gaming Co. deem
reasonably necessary and appropriate, provided that such changes are not
materially adverse to the interests of either Gaming Co., Company or Lakes.
Hilton shall use its reasonable best efforts to take all action necessary to
effect the Hilton Distribution prior to the Effective Time, pursuant to the
terms of the Hilton Distribution Agreement and the Hilton Ancillary Agreements.
Prior to the Effective Time and subject to the second preceding sentence, Hilton
will not agree to or permit any material modification of the terms of the Hilton
Distribution Agreement or the Hilton Ancillary Agreements that relate to the
Gaming Co. Business without the prior written consent of Company, which consent
will not be unreasonably withheld.

         (b)       Prior to the Closing, Company will, and will cause each of
its Subsidiaries that is a party thereto, to enter into the Company Distribution
Agreement and such ancillary agreements (the "Company Ancillary Agreements," and
together with the Hilton Ancillary Agreements, the

                                    - 56 -
<PAGE>   62
"Ancillary Agreements") as are reasonably required to effect the Company
Distribution and to govern the relationships between Company and Lakes following
the Company Distribution. The Company Distribution Agreement and the Company
Ancillary Agreements will conform in all material respects to the terms of the
subject forms attached hereto as Exhibit B, with such changes thereto as Company
and Lakes deem reasonably necessary and appropriate, provided that such changes
are not materially adverse to the interests of either Company, Hilton or Gaming
Co. Company shall use its reasonable best efforts to take all action necessary
to effect the Company Distribution prior to the Effective Time, pursuant to the
terms of the Company Distribution Agreement and the Company Ancillary
Agreements. Prior to the Effective Time and subject to the second preceding
sentence, Company will not agree to or permit any material modification of the
terms of the Company Distribution Agreement or the Company Ancillary Agreements
without the prior written consent of Hilton, which consent will not be
unreasonably withheld.

         Section 7.11.     Private Letter Ruling and Tax Opinions. Each of 
Hilton and Company shall use its reasonable best efforts and cooperate with the
other party and to obtain from the Service or tax counsel, as the case may be,
the Private Letter Rulings or tax opinions, as the case may be, contemplated by
Section 8.1(d) and 8.1(e) of this Agreement. Each party hereto shall also use
its reasonable best efforts to cause (a) the Merger to qualify as a
reorganization under the provisions of Sections 368(a)(1)(B) of the Code, (b)
the Hilton Distribution to qualify as a tax-free transaction to Hilton and its
stockholders within the meaning of Section 355 of the Code and (c) the Company
Distribution to qualify as a tax-free transaction, solely with respect to
Company's shareholders, within the meaning of Section 355 of the Code. Company
acknowledges, however, that (i) the Private Letter Ruling requested by Hilton
will also seek rulings with respect to the tax-free nature of certain other
transactions in which Hilton intends to engage after the Hilton Distribution
(the "Other Transactions") and (ii) Hilton will also be entitled to seek a
Private Letter Ruling that covers (and assumes the consummation of) such Other
Transactions in the Private Letter Ruling referred to above.

         Section 7.12.     NYSE Listing.  Gaming Co. shall use its reasonable  
efforts to cause the shares of Gaming Co. Common Stock to be issued in the
Merger to be approved for listing on the NYSE (or such other securities exchange
or market comprising the principal securities exchange on which the Gaming Co.
Common Stock is listed), subject to notice of official issuance, prior to the
Effective Time.

         Section 7.13.     Affiliate Agreements.  Upon the execution of this 
Agreement, Company will provide Hilton with a list of those Persons who are, in
Company's reasonable judgment, "affiliates" of Company within the meaning of
Rule 145 (each such Person who is an "affiliate" of Company within the meaning
of Rule 145 is referred to as an "Affiliate") promulgated under the Securities
Act ("Rule 145"). Company shall provide Hilton such information and documents as
Hilton shall reasonably request for purposes of reviewing such list and shall
notify Hilton in writing regarding any change in the identity of its Affiliates
prior to the Closing Date. Company shall each use all reasonable efforts to
deliver or cause to be delivered to Hilton by July 31, 1998 (and in any case
prior to the Effective Time) from each of its Affiliate, an executed Affiliate
Agreement, substantially in the form attached hereto as Exhibit C (an "Affiliate
Agreement").

Gaming Co. may be entitled to place appropriate legends on the certificates
evidencing any Gaming Co. Common Stock to be received by such Affiliates of
Company pursuant to the terms of this Agreement, and to issue appropriate stop
transfer instructions to the transfer agent for Gaming Co. Common Stock,
consistent with the terms of the Affiliate Agreements (provided that such
legends or stop transfer instructions shall be removed when such shares of
Gaming Co. Common Stock are generally transferable without any restrictions
imposed by Rule 145, upon the request of any shareholder that is not then an
Affiliate of Company).

         Section 7.14.     Stock Plans.

           (a)     At the Effective Time, each outstanding Company Stock Option 
under the Company Stock Plans, whether vested or unvested, shall be deemed to
constitute an option to acquire, on the same terms and conditions as were
applicable under such Company Stock Option the same number of shares of Gaming
Co. Common Stock as the holder of such Company Stock Option would have been
entitled to receive pursuant to the Merger had such holder exercised such option
in full immediately prior to the Effective Time (rounded to the nearest whole
number), at a price per share (rounded to the nearest whole cent) equal to (y)
the aggregate exercise price for the shares of Company Common Stock purchasable
pursuant to such Company Stock Option immediately prior to the Effective Time
divided by (z) the number of full shares of Gaming Co. Common Stock deemed
purchasable pursuant to such Company Stock Option in accordance with the
foregoing, it being acknowledged by Hilton that each such Company Stock Option
will, to the extent provided for in the applicable option or agreement, become
fully vested at the Effective Time as a result of the Merger.

           (b)     Promptly after the Effective Time, Gaming Co. shall deliver
to the participants in the Company Stock Plans appropriate notice setting forth
such participants' rights pursuant thereto and the grants pursuant to Company
Stock Plans shall continue in effect on the same terms and conditions (subject
to the adjustments required by this Section 7.14 after giving effect to the
Merger).

           (c)     Gaming Co. shall take all corporate action necessary to 
reserve for issuance a sufficient number of shares of Gaming Co. Common Stock
for delivery under Company Stock Plans assumed in accordance with this Section
7.14. Promptly after the Effective Time, Gaming Co. shall file a registration
statement on Form S-8 (or any successor or other appropriate forms), or another
appropriate form with respect to the shares of Gaming Co. Common Stock subject
to such options and shall use its reasonable best efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such options remain outstanding.

           (d)     The Board of Directors of Company shall, prior to or as of 
the Effective Time, take all necessary actions, pursuant to and in accordance
with the terms of the Company Stock Plans and the instruments evidencing the
Company Stock Options, to provide for the conversion of the Company Stock
Options into options to acquire Gaming Co. Common Stock in accordance with this
Section 7.14; and Company represents and warrants that no consent of the holders
of the Company Stock Options is required in connection with such conversion.

                                    - 58 -

           (e)     The Board of Directors of Company shall, prior to or as of 
the Effective Time, take appropriate action to approve the deemed cancellation

The Board of Directors of Gaming Co. shall, prior to or as of the Effective

Gaming Co. Common Stock under the Company Stock Options (as converted pursuant
to this Section 7.14) for purposes of Section 16(b) of the Exchange Act.

         Section 7.15.     Indian Gaming and Debt Agreements and Lakes 
Agreements. Subject to Lake's obligations to indemnify the Surviving Corporation
with respect to such obligations pursuant to Section 7.9 hereof and Article V of
the Company Distribution Agreement, the Surviving Corporation shall comply with
all of Company's obligations under any Indian Gaming and Debt Agreements or
Lakes Agreements to which it is a party or subject to and for which it has not
been released.

         Section 7.16.     Conveyance Taxes. Hilton and Company shall cooperate
in the preparation, execution and filing of all returns, questionnaires,
applications or other documents regarding any real property transfer or gains,
sales, use, transfer, value added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees or any similar taxes which become payable
in connection with the transactions contemplated by this Agreement that are
required or permitted to be filed on or before the Effective Time. Company shall
pay, without deduction or withholding from any amount payable to the holders of
Company Common Stock, any such taxes or fees imposed by any Governmental
Authority (and any penalties and interest with respect to such taxes and fees)
which become payable in connection with the transactions contemplated by this
Agreement on behalf of its shareholders.

         Section 7.17.     Stockholder or Shareholder Litigation. Each of Hilton
and Company shall give the other the reasonable opportunity to participate in
the defense of any stockholder or shareholder litigation against Hilton or
Company, as applicable, and its directors relating to the transactions
contemplated hereby.

         Section 7.18.     Employee Benefits.

           (a)     Gaming Co. shall or shall cause the Surviving Corporation to
maintain in effect employee benefit plans and arrangements which provide
benefits which have a value which is substantially comparable, in the aggregate,
to the benefits provided by the Employee Benefit Plans (not taking into account
the value of any benefits under any such plans which are equity based) for a
period of one year after the Effective Time.

           (b)     Gaming Co. shall or shall cause the Surviving Corporation to
honor all employment, severance and termination agreements (including change in
control provisions) of the employees of Company and its Subsidiaries in effect
on the date hereof; provided that (x) all such agreements are set forth or
summarized on the Company Disclosure Schedule, (y) such agreements will not be
amended, modified or extended after the date hereof without the written consent
of Hilton and (z) to the extent such agreement would unjustly or inequitably
enrich such employee, the foregoing commitment shall not apply to any Persons
who become employees of 

                                    - 59 -
<PAGE>   65
any member of the Lakes Group and shall instead become a commitment of Lakes who
shall honor any such agreement.

           (c)     For purposes of determining eligibility to participate and

relevant under any employee benefit plan or arrangement of Gaming Co. or the
Surviving Corporation, employees of Company and its Subsidiaries as of the
Effective Time shall receive service credit for service with Company and any of
its Subsidiaries to the same extent such service was granted under the Employee
Benefit Plans.

the Surviving Corporation to comply with any "Change of Control Offer" (as

the conditions set forth in this Agreement, each of the parties hereto agrees to
use all reasonable best efforts to take, or cause to be taken, all actions, and
to do, or cause to be done, and to assist and cooperate with the other party in
doing, all things necessary, proper or advisable to satisfy the conditions set
forth in Section 8.1(j) below.

and shall cause the Surviving Corporation to, maintain and observe Company's
marketing agreements with each of the Coushatta Tribe of Louisiana and the

existing, neither Gaming Co. nor Surviving Corporation shall directly or
indirectly engage in Restricted Activities in the following markets: (i) greater
Houston, Texas; (ii) greater Alexandria, Louisiana; (iii) greater Baton Rouge,
Louisiana; or (iv) greater Lafayette, Louisiana; provided, however, that nothing
herein shall prevent the Surviving Corporation from directly mailing any

individuals or entitles that are included in the Surviving Corporation's patron
database; and provided further, however, that nothing herein shall prevent
Gaming Co. from marketing or advertising its casinos (or employing its related

         Section 8.1     Conditions to Each Party's Obligation to Effect the
Merger. The respective obligations of each party to this Agreement to effect
the Merger shall be subject to the satisfaction or waiver prior to the Effective
Time of the following conditions:

           (a)     Shareholder Approval. Company shall have obtained the Company
Shareholder Approval.

           (b)     HSR Act. The waiting period (and any extension thereof)

projections or schedules (other than the financial schedules, budgets or pro
formas described or referred to in Sections 3.1(c), 4.19, 4.20 or 5.14 of this
Agreement) heretofore or hereafter delivered to or made available to any such
Persons or their counsel, accountants, advisors, representatives or Affiliates

any documentation or other information with respect to any one or more of the
foregoing; it being understood that each party hereto has not and will not rely
on any financial projections or schedules (other than the financial projections
or schedules described or referred to in Sections 3.1(c), 4.19, 4.20 or 5.14 of
this Agreement) in connection with its evaluation of any other party hereto or
the Merger.

         Section 10.6.     Governing Law. This Agreement shall be governed and 
construed in accordance with the laws of the State of New York without regard to
any applicable conflicts of law, including all matters of construction,
validity, and performance, except to the extent that the provisions of the DGCL
or the MBCA and applicable Gaming Laws shall be mandatorily applicable to the
Merger or this Agreement.

         Section 10.7.     Assignment. Neither this Agreement nor any of the 
rights, interests or obligations hereunder shall be assigned by any of the
parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other parties. Subject to the preceding sentence, this
Agreement will be binding upon, inure to the benefit of and be enforceable by
the parties and their respective successors and assigns.

         Section 10.8.     Headings; References. The article, section and 
paragraph headings and table of contents contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement. All references herein to "Article," "Sections"
or "Exhibits" shall be deemed to be references to Articles or Sections hereof or
Exhibits hereto unless otherwise indicated.

         Section 10.9.     Severability; Enforcement. Except to the extent that 
the application of this Section 10.9 would have a Material Adverse Effect with
respect to Hilton, Gaming Co. or Company, the invalidity of any portion hereof
shall not affect the validity, force or effect of the remaining portions hereof.
If it is ever held that any covenant hereunder is too broad to permit
enforcement of such covenant to its fullest extent, each party agrees that a
court of competent jurisdiction may enforce such covenant to the maximum extent
permitted by law, and each party hereby consents and agrees that such scope may
be judicially modified accordingly in any proceeding brought to enforce such
covenant.

         Section 10.10.     Specific Performance. The parties hereto agree that
the remedy at law for any breach of this Agreement will be inadequate and that
any party by whom this Agreement is enforceable shall be entitled to specific
performance in addition to any other appropriate relief or remedy. Such party
may, in its sole discretion, apply to a court of competent jurisdiction for
specific performance or injunctive or such other relief as such court may deem
just and proper in order to enforce this Agreement or prevent any violation
hereof and, to the extent permitted by Applicable Laws, each party hereto waives
any objection to the imposition of such relief.

         Section 10.11.     Effect of Hilton Distribution. The parties 
acknowledge that Hilton may effect the Hilton Distribution in advance of the
Effective Time. From and after the effectiveness of the Hilton Distribution: (i)
the rights and obligations of Hilton contained in each of the Transaction
Documents shall become the rights and obligations solely of Gaming Co., and
Hilton shall have no further obligations under each of the Transaction
Documents; (ii) all covenants

under each of the Transaction Documents to be performed by Hilton will be
performed by (and appropriately construed as covenants of) Gaming Co.; (iii) all
covenants under each of the Transaction Documents to be performed for the
benefit of Hilton will be performed (and appropriately construed as covenants)
for the benefit of Gaming Co. and all payments to be made to Hilton shall
instead be paid to Gaming Co.; and (iv) the representations and warranties of
Hilton shall be representations and warranties of Gaming Co., unless by their
context such representations and warranties are not appropriate to Gaming Co.,
appropriately modified to give effect to the transactions contemplated by this
Agreement and the Hilton Distribution Agreement.

         Section 10.12.     Approvals, Consent and Waivers. Any approval, 
consent or waiver required or authorized by any provision of this Agreement to
be given or made by any of the parties hereto shall only be valid to the extent
such approval, consent or waiver is in writing and signed by, with respect to
either Hilton, Gaming Co. or Merger Sub, the Executive Vice President & Chief
Financial Officer, the Executive Vice President & General Counsel, the Senior
Vice President & Treasurer or the Senior Vice President & Controller, and with
respect to either Company or Lakes, the Chairman of the Board of Directors, the
President and Chief Executive Officer or the Chief Financial Officer, of the
party to be bound by such approval, consent or waiver.
