responsible for all such claims of its employees based on injuries occurring on

current employees of the Sellers.

     5.3  Employee Benefit Plans.  The Company shall not have any liability or

such liability and shall jointly and severally indemnify and hold the Company
harmless against such liability.

partnership duly formed and validly existing under the laws of the State of
Florida; has all requisite power and authority to own its property and to carry
on its business as now being conducted; and is duly qualified to do business in
each jurisdiction in which the character of its properties and assets owned or
leased or the nature of its business transacted, makes such qualification
necessary.  Copies of the Joint Venture Agreements for each of the Sellers, as
amended to date, (the "Joint Venture Agreements") which have been delivered to
Purchasers are complete and correct, and no amendments have been made thereto
since the date hereof.

     7.2 Subsidiaries and other Equity Investments.  Neither Seller owns,
directly or indirectly, any shares of capital stock of any corporation or any
equity investment in any partnership, association or other business

execution and delivery of this Agreement by each Seller and the performance by
it of all obligations contemplated hereby have been duly authorized by all
requisite partnership actions including the approval of all the partners of
each Seller.  This Agreement and all other agreements entered into in
connection with the transactions contemplated hereby to 


                                    -12-

the consummation of any of the transactions contemplated hereby, nor the
fulfillment of any of the terms hereof except to the extent disclosed herein or
in any Schedule hereto (i) will violate or conflict with the Joint Venture
Agreements, (ii) will result in any breach of or default under any provision of
any contract or agreement of any kind to which either Seller is a party or by
which either  Seller is bound or to which any property or asset of either
Seller is subject, which would have a material adverse effect on the
Transferred Assets, or (iii) will result in a violation of any statutes, laws,
ordinances, rules, regulations or requirements of governmental authorities

          (l) entered into any lease of real or personal property which

of more than one year;

          (m) except for the amendment to the Homested Lease reflected on

any material contract, agreement or license to which such Seller is a party
other than in the ordinary course of business;
        
          (n) had any resignation or termination of employment of any of its key

     7.8  Title to and Condition of Properties and Assets.  Immediately prior to

in paragraph 2 above (the "Transfer Time"), Sellers had good title to all of
their tangible personal properties including, without limitation, (i) all those
used in the business of 



                                    -16-
<PAGE>   17

Sellers and (ii) those reflected in the Financial Statements (except as sold or
otherwise disposed of in the ordinary course of business).  All tangible
personal properties are subject to no mortgage, pledge, conditional sales
contract, lien, security interest, right of possession in favor of any third
party, claim or other encumbrance, except (i) the lien of current real estate
taxes not yet due and payable, (ii) as set forth in Schedule 7.8, (iii) as
reflected in the Financial Statements, (iv) for such minor imperfections of
title, if any, as do not interfere with the present use of the property or
properties subject thereto or affected thereby in a manner materially adverse
to the business of Sellers, and (v) for liens not material in amount and
arising from the ordinary course of conduct of the business of Sellers. 
Immediately prior to the Transfer Time, all such properties and assets
reflected in the Financial Statements had a fair market or realizable value
determined on a going business basis at least equal to the value thereof as
reflected herein.  Subsequent to December 31, 1996, except as contemplated by
this Agreement, Sellers have not sold or disposed of any of their tangible
personal properties or assets or obligated themselves to do so except in the
ordinary course of business.  Except as disclosed on Schedule 2.2, the
facilities, machinery, furniture, office and other equipment (including
computer software) of Sellers that were transferred to the Company as
contemplated in paragraph 2 above, are in good operating condition and repair,
subject only to ordinary wear and tear.  Sellers have not received any written
notice from any governmental agency, board, bureau, body, department or
authority of any federal, state, municipal or foreign jurisdiction, to the
effect that Sellers or any tangible personal property or asset owned or leased
by Sellers, which was transferred to the Company as contemplated in paragraph 2
above,  is in violation of any applicable ordinance, regulation or building,
zoning, environmental or other law in respect thereof, the violation of which
will have a material adverse effect on the conduct of the business or the
ownership or use of any of such properties or assets.  Since December 31, 1996,
except as disclosed on Schedule 7.8, there has not been any significant
        


                                    -17-
<PAGE>   18

interruption of the operations of Sellers due to inadequate maintenance of
structures, machinery or equipment or because of computer software or data
processing failures.

     7.9. Real Estate Leases.

          (a) Schedule 2.3, sets forth a list of the Real Property Leases.  
Sellers have furnished Purchasers with a copy of the Real Property Leases. 
Each Real Property Lease is in full force and effect against the Company and is
valid and enforceable by the Company, in accordance with its terms, assuming
the due authorization, execution and delivery thereof by each of the other
parties thereto.  There is not under any Real Property Lease any material
default of Sellers or the Company, or any event that with notice or lapse of
time or both would constitute such a material default with respect to which
Sellers have not taken adequate steps to prevent such default from occurring;
all of such events, if any, and the aforesaid steps taken by Sellers are set
forth in Schedule 7.9.  To the knowledge of Sellers, there is not under any
Real Property Lease any default by any other party thereto or any event that
with notice or lapse of time or both would constitute such a default thereunder
by such party.
        
          (b) Sellers have not received any written notice that the use of any
improvements to the property subject to the Real Property Leases and the
conduct of Sellers' business thereon prior to the Closing was in violation of
any law, statute, ordinance, rule or regulation of any government, governmental
body, agency or authority (federal, state, municipal, foreign or local) in any
material respect.

          (c) Except as disclosed on Schedule 7.9 hereto, to the knowledge of
Sellers there are no material defects or deficiencies with respect to the
design or construction of the Complex.

      involving the payment of more than $25,000 annually;

           (xi)    contract with any party that to the knowledge of Sellers
      is expected to result in a material loss; or

           (xii)   other contract or agreement, except insubstantial
      contracts for supplies or services or not involving the payment of
      more than $25,000 annually.

      Except as set forth on Schedule 2.9 or otherwise herein, immediately prior
to the Transfer Time, neither Seller was a party to any material contract with
any governmental authority. Each Contract listed in Schedule 2.9 was in full
force and effect against Sellers and is valid and enforceable by Sellers, in
accordance with its terms, assuming the due authorization, execution and
delivery thereof by each of the other parties thereto.  Neither of the Sellers
nor, to the knowledge of Sellers, any other party is in default in the
observance or the performance of any material term or obligation to be
performed by it under any Contract listed in said Schedule 2.9.  To the
knowledge of Sellers, no other person is in default in the observance or the
performance of any material term or obligation to be performed by it under any
Contract listed in said Schedule 2.9.  Sellers will provide to Purchasers prior
to the Closing Date true and complete copies of all Contracts listed in
Schedule 2.9 as in effect on the date hereof.

      7.11  Certain Indebtedness.  Schedule 7.11 is a correct and complete list
of all instruments, agreements and arrangements pursuant to which either Seller
has borrowed money, incurred any indebtedness or established any line of credit
which represents a liability of such Seller immediately prior to Transfer Time.
True and complete copies of all such instruments, agreements and arrangements
that are in writing and summaries of all others thereof have heretofore been
delivered to Purchasers.  All of such indebtedness has been incurred for valid
business purposes of Sellers.  Sellers were not in material default under any
indenture, loan agreement or any other agreement relating to borrowed money to
which either of the Sellers is a party or by which either of the Sellers or
their assets or properties are bound nor did any condition exist which, with
notice or lapse of time or both, would constitute such a default, and each such
indenture, loan agreement or other agreement was in full force and effect
against Sellers.

      7.12  Litigation.  Except as set forth on Schedule 7.12, immediately prior
to the Transfer Time, there were no actions, suits, proceedings or
investigations, either at law 





                                    -20-
<PAGE>   21

or in equity, or before any commission or other administrative authority in any
federal, state, municipal or foreign jurisdiction, of any kind now pending or,
to the best of knowledge of Sellers, threatened or proposed in any manner, or,
to the knowledge of Sellers, any circumstances which reasonably form the basis
of any such action, suit, proceeding or investigation, involving Sellers or any
of their properties or assets that (i) if asserted and decided adversely to
Sellers, would materially and adversely affect the operations or the business
of Sellers, or of the Company or its successors or assigns with respect to the
Transferred Assets, or (ii) questions the validity of this Agreement, or (iii)
seeks to delay, prohibit or restrict in any manner any action taken or
contemplated to be taken by Sellers under this Agreement.  Except as set forth
in Schedule 7.12, there is no arbitration proceeding pending or, to the
knowledge of Sellers, threatened with respect to individual claims under any
collective bargaining agreement or other agreement which claims, individually
or in the aggregate, if adversely decided could have a material adverse effect
on the business or operations of the Company.  Neither the Company nor any of
its properties or assets is subject to any judicial or administrative judgment,
order, decree or restraint.  Except as set forth on Schedule 7.12, there have
been no actions, suits, proceedings or investigations, either at law or in
equity, or before any commission or other administrative authority in any
federal, state, municipal or foreign jurisdiction of any kind which were
material and were initiated against either of the Sellers and settled or
otherwise resolved prior to the date hereof.
        
     7.13  Proprietary Rights.  Except as set forth on Schedule 7.13, there are
no claims, demands or proceedings pending or, to the actual knowledge of
Sellers,  threatened that pertain to or challenge the right of Sellers or the
Company to use the Proprietary Rights identified in Schedule 2.1 and no valid
basis exists for any such claim. Neither of the Sellers knows of any third
party that has infringed on any of Sellers' Proprietary Rights.  Except for the
transfer to the Company contemplated by this Agreement, Sellers have not
granted any licenses or other rights with respect to the 


                                    -21-
<PAGE>   22

Proprietary Rights and has no legally binding obligation to grant licenses or
other rights.  The Proprietary Rights identified in Schedule 2.1 constitute all
trademarks, service marks, trade names and copyrights which were owned by
Sellers and which are used or are required in connection with the operation of
Sellers' business including the operation of the Complex immediately prior to
the Transfer Time. Except for the rights of the City of Homestead and Dade
County specified in the Homestead Lease, and subject to the rights granted in
the Contracts disclosed on Schedule 2.9, Sellers are the sole and exclusive
owner of, and have the sole and exclusive right to use, the Proprietary Rights
all of which were assigned to the Company free and clear of all claims, liens,
charges or any encumbrances whatsoever.  Except as disclosed in Schedule 2.1,
Sellers have not allowed any material Proprietary Rights to lapse.
        
     7.14  Compliance with Laws.  Sellers and the Company  have complied with
and are in compliance with all material federal, state, local and foreign
statutes, laws, ordinances, regulations, rules, permits, judgments, orders or
decrees applicable to Sellers and the Company and their properties and assets,
operations and business, and there does not exist, to the best of Sellers'
knowledge, any basis for any claim of default under or violation of any such
statute, law, ordinance, regulation, rule, judgment, order or decree.  In all
material respects immediately prior to the Transfer Time, Sellers were in
compliance with (i) all applicable requirements of all United States and
foreign governmental authorities with respect to environmental protection,
including, without limitation, regulations establishing quality criteria and
standards for air, water, land and hazardous materials, and (ii) all applicable
laws and related rules and regulations of all federal, state, municipal and
foreign jurisdictions affecting sale of alcoholic beverages, public health and

Labor Relations Act, as amended and to the knowledge of Sellers in all material
respects with the Americans With Disabilities Act, as amended.
        
     7.15  Governmental Authorizations and Regulations.  Schedule 7.15 lists all
licenses, franchises, permits and other governmental authorizations held by
Sellers immediately prior to the Transfer Time material to the conduct of their
business.  Such licenses, franchises, permits and other governmental
authorizations were valid, and Sellers had not received any written notice that
any governmental authority intends to cancel, terminate or not renew any such
license, franchise, permit or other governmental authorization. The Company
holds all licenses, franchises, permits and other governmental authorizations
the absence of any of which would have a material adverse effect on its
business.

Sellers have delivered or made available to Purchaser true and complete copies

(as defined in Section 4975 of the Code and Section 3 of ERISA, respectively)
has engaged in any "prohibited transaction," as such term is defined in Section
4975 of the Code or Section 406 of ERISA, which would subject any Employee
Benefit Plan or its related trust, Sellers, the Company or any officer,
partner, director, member  or employee of Sellers, the Company, or any trustee,

liability under Section 4975 of the Code or Section 502(i) of ERISA or any

suits or claims pending (other than routine claims for benefits) or, to the
knowledge of Sellers, threatened, against any Employee Benefit Plan or against
the assets of any Plan; (vi) no Employee Benefit Plan, other than any Employee

<PAGE>   25

Title IV of ERISA and Sellers have not incurred any liability to the Pension 
Benefit Guaranty Corporation ("PBGC").

     (c)  Except as set forth in Schedule 7.16, there are no multi-employer
plans, within the meaning of Section 3(37) of ERISA, to which Sellers are or,
at any time since their formation, have been required to make any contributions
to under which either Seller is subject to any material liability, actual or
contingent.  With respect to each multi-employer plan listed in Schedule 7.16
that is or was subject to Title IV of ERISA (i) there has been no complete
withdrawal or partial withdrawal of either Seller, as defined in Section 4201,
4203 and 4205 of ERISA and neither Seller has received any notice of withdrawal
liability pursuant to Sections 4202 or 4219 of ERISA, (ii) neither Seller has

disclosed on Schedule 7.16, including any material fact relating to the
existence of an accumulated funding deficiency, as defined in Section 412 of
the Code or a determination that the plan is insolvent, in reorganization or
the subject of termination proceedings.  The aggregate contingent withdrawal
liability of Sellers with respect to the multi-employer plans listed in
Schedule 7.16 does not exceed, as of the date hereof, $25,000.

     (d)  The current value of all vested Accrued Benefits under all Employee
Benefit Plans, other than multi-employer plans, as of the date of this
Agreement, did not exceed the then Current Value of the assets of such Plans
allocable to such vested Accrued Benefits by more than $25,000.  For purposes
of the representation in the preceding sentence, (i) the term "Current Value"
has the same meaning as in section 4062(b)(1) of ERISA and the term "Accrued
Benefit" has the meaning specified in Section 3 of ERISA.



                                    -25-
<PAGE>   26

           (e) Each "group health plan" (within the meaning of 
Section 162(i)(3) of  the Code) maintained by each of the Sellers has been
administered in compliance with the continuation coverage requirements
contained in the Consolidated omnibus Budget Reconciliation Act of 1985 and as
provided under Section 162(k) of the Code and all regulations promulgated or
proposed thereunder.
        
     7.17  Accounts Receivable.  All Accounts Receivable are listed on Schedule
7.17.  The Accounts Receivable represent transactions actually made in the
ordinary course of business and relate to events, transactions or services
occurring or scheduled to occur at the Complex, and are current and collectible
without discount.  Each of the Accounts Receivable listed on Schedule 7.17 will
be collected in full, without any set-off or counter claim, within 90 days
after the Closing Date (provided that the Company complies with its collection
efforts obligations under paragraph 9.2 below) except as noted on Schedule
7.17.  With respect to the Accounts Receivable listed on Schedule 7.17 as
"collection doubtful within 90 days" (the "Slow Accounts"), such Slow Accounts
will be collected in full, without any set off or counterclaims, within 120
days after the Closing Date provided that the Company complies with its
collection efforts obligations under paragraph 9.2 below and subject to an
allowance of $25,000 for uncollectible Slow Accounts.  Except as disclosed on
Schedule 7.17, since December 31, 1996 no Accounts Receivable of Sellers have
been written off as uncollectible.

     7.18  Inventory.  All inventories of Sellers reflected in the balance sheet
included with the Financial Statements consist of a quality and quantity usable
and salable in the ordinary course of business without material discount or
reduction, except for items of obsolete materials and materials of
below-standard quality, all of which have been written down on Sellers' June
30, 1997 balance sheet to realizable market value or for which adequate
reserves have been provided therein.

     7.19  Taxes.  Each of the Sellers has duly and timely filed, within
applicable extension periods, all tax reports and returns required to be filed
by it and Sellers have 


                                    -26-
<PAGE>   27

duly and timely paid all taxes with respect to the business of the Sellers by
federal, state, local or foreign taxing authorities (including, without
limitation, those due in respect of the tangible and intangible properties,
leasehold interests, income, franchises, licenses, sales or payrolls of
Sellers); and there are no tax liens or encumbrances upon any property or
assets of Sellers except liens for current taxes not yet due.  The federal
partnership tax returns of Sellers have never been audited by the Internal
Revenue Service.  Except to the extent set forth in Schedule 7.19, there are no
outstanding agreements or waivers extending the statutory period of limitation
applicable to any federal partnership tax return for any period. Copies of all
partnership tax returns for Sellers in respect of all years not barred by the
statute of limitations have heretofore been delivered by Sellers to Purchaser
and all such returns are listed in Schedule 7.19.
        
     7.20  Insurance.  Schedule 7.20 contains an accurate and complete
description of all material policies of fire, liability, workmen's
compensation, errors and omissions and other forms of insurance owned or held
by Sellers immediately prior to the Transfer Time.  Immediately prior to the
Transfer Time, all such policies were in full force and effect, all premiums
due and payable with respect thereto covering all periods up to and including
the date of the Closing had been paid, and no written notice of cancellation or
termination had been received with respect to any such policy.  Immediately
prior to the Transfer Time, such policies were sufficient for compliance with
all requirements of law and of all agreements to which either Seller was a
party; were valid, outstanding and enforceable policies; provide insurance
coverage customary in Sellers' industry for the assets and operations of
Sellers; will remain in full force and effect through the respective dates set
forth in Schedule 7.20 without the payment of additional premiums.  Schedule
7.20 identifies all risks which Sellers designated as being self-insured.
Neither Seller has been refused any insurance with respect to its assets or
operations, nor has its coverage been limited, by any insurance 



                                    -27-
<PAGE>   28

carrier to which it has applied for any such insurance or with which it has
carried insurance during the last three years.
        
     7.21  Certain Transactions.  Except as set forth in Schedule 7.21, or
elsewhere set forth herein, there was no transaction or contractual
relationship relating to the Transferred Assets and existing immediately prior
to the Transfer Time, to which either Seller was a party and in which any
partner or officer of Sellers or any affiliate of Sellers had a direct or
indirect material interest.

     7.22  Accounting Practices.  Each Seller makes and keeps accurate books and
records reflecting its assets and operations in accordance with generally
accepted accounting principals consistently applied ("GAAP") and maintains
internal accounting controls that provide reasonable assurance that (i)
transactions are executed in accordance with proscribed policies and with
management's authorization, (ii) all valid transactions are properly valued and
timely and accurately recorded so as to permit timely preparation of financial
statements in accordance with GAAP, (iii) access to the assets of such Seller
is permitted only in accordance with proscribed policies and management's
authorization and (iv) the reported accountability of the assets of such Seller
is compared with existing assets at reasonable intervals.

     7.23  Certain Disclosures.  Schedule 7.23 sets forth the following
information with respect to the period immediately prior to the Transfer Time:

                 (i) a list of all officers and other employees and consultants
           of each Seller whose current annual salary or rate of compensation
           (including committed or anticipated bonus and incentive
           compensation) was more than $50,000 or to whom either Seller had
           loaned more than $25,000 reflecting on such list the amount and
           nature of all cash and non-cash compensation;

                 (ii) a list of all officers and other employees and
           consultants of either Seller who were receiving or are entitled to
           receive any payment

<PAGE>   29

           (other than salaries, expense reimbursements, bonuses, merit and 
           incentives compensation) indicating on such list the amount and 
           nature of each payment; and

                 (iii) a list of all vehicles owned or leased by either Seller
           or which was otherwise used in connection with the operation of the
           business of either Seller.

     7.24  Labor Agreements and Policies.  Immediately prior to the Transfer
Time, neither Seller was a party to or bound by any collective bargaining
agreement.  Each Seller had complied with all applicable federal and state laws
with respect to hours worked by, working conditions and any payments made to
its employees and the classification of individuals performing services for
each Seller as an employee or independent contractor.

     7.25  Schedules.  All lists or other statements, information or documents
set forth in or attached to any Schedule delivered or to be delivered pursuant
to this Agreement shall be deemed to be representations and warranties of the
parties making them with the same force and effect as if such lists,
statements, information and documents were set forth herein.  Any list,
statement, document or any information set forth in or attached to any Schedule
delivered or required to be delivered pursuant to this Agreement shall be
deemed to constitute disclosure for any other Schedule delivered or to be
delivered pursuant to this Agreement.

     7.26  No Untrue Statements.  No statement by either Seller contained in
this Agreement contains any untrue statement of a material fact, or omits to

and operating 


                                    -34-
<PAGE>   35

control of the Transferred Assets, and Sellers agree that at any time or from
time to time after the Closing Date, upon the request of the Company, Sellers
will execute, acknowledge and deliver such other instruments of conveyance and
transfer and take such other action as the Company may reasonably require to
vest more effectively in the Company good and marketable title to any of the
Transferred Assets and to reasonably assist and cooperate in collection of any
of the the Accounts Receivable.  Without limiting the generality of the
foregoing, at the option of the Company, Sellers shall participate in taking
such action as may be necessary to substitute the Company for Sellers as
plaintiff or claimant of record in any action, suit, proceeding or claim by
Sellers with respect to or based upon or arising out of the business of Sellers
to the extent that such substitution will not materially adversely affect any
such action, suit, proceeding or claim, in which event Sellers shall remain as
plaintiff or claimant with counsel approved by the Company on behalf of and for
the benefit of the Company.  In the event that Sellers remain as plaintiff or
claimant, Sellers shall remit to the Company all amounts paid to Sellers on
account of any judgment, order, settlement or payment resulting from any such
action, suit, proceeding or claim and the Company shall bear the costs and
expenses incurred by Sellers after the Closing in connection therewith.  In no
event shall the Sellers be obligated to expend more than $50,000 after Closing
with respect to out-of-pocket expenses incurred in fulfilling obligations under
the terms of this paragraph 9.1.  At any time or from time to time after the
Closing, the Company shall, at the request of Sellers, execute and deliver any
further instruments or documents and take all such further action as Sellers
reasonably request in order to evidence the consummation of the transactions
contemplated hereby.
        
     9.2  Accounts Receivable Collection.  The Company shall exercise its
reasonable commercial efforts to collect the Accounts Receivable but shall not
be obligated to initiate litigation as part of such collection efforts.  All
payments received by the Company after the Transfer Time from third parties who
are the obligors on the 



                                    -35-
<PAGE>   36

Accounts Receivable shall be applied to the oldest remaining Accounts
Receivable for such third party unless otherwise indicated on any remittance
advice from such third party which accompanies such payment. Any Account
Receivable which remains unpaid after 90 days from the Closing (or after 120
days from the Closing with respect to the Slow Accounts), and with respect to
which the Purchasers or the Company obtain payment from Sellers under paragraph
13.1, shall be reassigned to Sellers for collection by Sellers for their own
account.
        
     9.3  Retained Information.  From and after the Closing Date, the Sellers
shall not retain any records or other documents related to the business or
operations of the Complex prior to the Effective Time (the "Transferred
Business Records") other than records or other documents which constitute part
of the Excluded Assets.  For a minimum of five (5) years after the Closing, the
Company shall maintain and make available to Sellers the Transferred Business
Records for inspection and copying to the extent Sellers require access to such
records in response to tax audits or other reasonable business necessity
provided that such records shall not be used in a manner which is detrimental
to the interests of the Company.  For a minimum of five (5) years after the
Closing, the Sellers shall maintain and make available to the Company the
Retained Business Records for inspection and copying to the extent the Company
requires access to such records for reasonable business necessity provided that
such records shall not be used in a manner which is detrimental to the
interests of the Sellers.  Nothing contained in this paragraph 9.3 shall
restrict either Sellers or the Company from obtaining access to the Transferred
Business Records or the Retained Business Records incident to discovery in
litigation to which the Company or Sellers are parties and utilizing such
records with respect to any such litigation.

     9.4  Publicity.  No party to this Agreement shall make or issue, or cause
to be made or issued, any announcement or written statement concerning this
Agreement or the transactions contemplated hereby for dissemination to the
general public without 


                                    -36-
<PAGE>   37

the prior consent of the other.  This provision shall not apply, however, to
any announcement or written statement required to be made by law or the
regulations of any federal, state or foreign governmental agency or any stock
exchange, except that the party required to make such announcement shall,
whenever practicable, consult with the other party concerning the timing and
content of such announcement before such announcement is made.
        
     9.5   Special Provisions Addressing Deferred Income and Prepaid Event
Expenses.

           9.5.1 The parties hereto acknowledge that inherent in the operation
of Sellers' business prior to the Effective Time was (i) the action of selling
admission tickets, sponsorships, signage, suite rentals and other revenue items
which are either specific to an event or specific to a period of time, and
typically, many of these sales are made and payment is received in advance of
the event or time period, and (ii) the necessity from time to time to prepay
certain expenses which are directly related to a future event, including, but
not necessarily limited to, advertising or promotional expenses.
        
           9.5.2 The parties hereto also acknowledge that GAAP requires (i) 
sales made in advance of a specific event or time period to be recorded on the
balance sheet as a liability, hereinafter referred to as "Deferred Income", and
(ii) material expenses paid in advance of a specific event be recorded in the
balance sheet as an asset, hereinafter referred to as "Prepaid Event Expense".
        
           9.5.3 Sellers warrant that (i) sales made or contracts entered into
in advance of the Effective Time that relate to obligations that the Company
must perform subsequent to the Effective Time, have been recorded on the
Sellers' combined balance sheet as Deferred Income.  Furthermore, Schedule 9.5
accurately lists the components of Deferred Income as of the Effective Time
and, (ii) all material expenses paid by Sellers prior to the Effective Time
that directly relate to events which are scheduled to occur 
        


                                    -37-
<PAGE>   38

subsequent to the Effective Time have been accounted for on the Sellers'
balance sheet as Prepaid Event Expenses.  Furthermore, Sellers warrant that
Schedule 9.5 is a complete and accurate list of Prepaid Event Expenses as of
the Effective Time, and that these Prepaid Event Expenses represent direct
costs relating to scheduled events that will occur subsequent to the Effective
Time.  Furthermore, Sellers warrant that the Prepaid Event Expenses listed on
Schedule 9.5 do not include any allocation of indirect expenses, including, but
not necessarily limited to, selling, general and administrative expenses.
        
     9.6  Definition of Material.  Except to the extent that different criteria
are specified with respect to a specific paragraph of this Agreement, an event,
occurrence or circumstance will be deemed to be "material" with respect to a
party if such event, occurrence or circumstance causes or is reasonably likely
to cause damage, loss or expense to such party in excess of $5,000.00.

     9.7  Limitation on Transfer of Membership Interests.

          9.7.1 Sanchez Membership Interest.  Sanchez and the Sellers agree 
that, except as is contemplated by this Agreement, they will not transfer or
permit to be transferred the Sanchez Membership Interest, as that term is
defined below, as long as the call option for the Sanchez Membership Interest
specified in paragraph 25.4 is outstanding.
        
          9.7.1 Huizenga Membership Interest. Huizenga and the Sellers agree 
that, except as is contemplated by this Agreement, they will not transfer or
permit to be transferred the Huizenga Membership Interest, as that term is
defined below, as long as the call option for the Huizenga Membership Interest
specified in paragraph 25.3 is outstanding.
        
     9.8  Additional Capital.  Additional capital requirements of the Company
arising after the Closing Date shall be determined by a Majority in Interest of
the Members, as that term is defined in the Company's Operating Agreement,
applying 


                                    -38-
<PAGE>   39

commercially reasonable business judgment and based on the reasonable business
needs of the Company.  In the event that the Company is not able to satisfy its
additional capital requirements by loans from financial institutions on
commercially reasonable terms, the Members of the Company shall be required to
make additional capital contributions in proportion to their Percentage
Interests in the Company as that term is defined in the Company's Operating
Agreement.  If a capital call is made on the Members of the Company prior to
the expiration of the put option for the Sanchez Membership Interest specified
in paragraph 25.2 below, ISC and PMI, upon request from Sanchez, will each
advance to the Company, on behalf of the Member owning the Sanchez Membership
Interest, one half of the cash call due from such Member  until the aggregate
of the advances made by ISC and PMI (the "Advances") on behalf of such Member
total $1,000,000.  The Advances will earn interest from the date of each
Advance at the floating market rate charged to the party making the Advance by
its principal lending bank.  The Advances plus all accrued interest shall be
secured by the Sanchez Membership Interest.  Sanchez hereby consents that any
proceeds from the sale of the Sanchez Membership Interest pursuant to the put
option set forth in paragraph 25.2 or the call option set forth in paragraph
25.4  shall be applied first to pay in full the outstanding balance of the
Advances plus all accrued interest.
        
     9.9  Huizenga Special Use Rights.  For a period of ten years from the
Closing or until the death of Huizenga, whichever shall occur first, Huizenga
or an entity controlled by him will have the right to use the Complex four days
per calendar year to entertain his employees and guests with a driving school.
Huizenga's rights under this paragraph 9.9 shall be subject to the following
limitations:

               (i)  During the period between January 2 and January 31 of each
calendar year, Huizenga shall request dates for the use of the Complex  during
such calendar year and the Company shall approve such dates if they do not
interfere with other scheduled uses for the Complex.  The Company shall be
permitted to reschedule 
        


                                    -39-
<PAGE>   40

any date selected by Huizenga upon written notice given to Huizenga not less
than 30 days prior to the scheduled date, for good cause as determined in the
Company's commercially reasonable judgment.  An example of good cause would be
an alternative use for the Complex which would generate significant revenue for
the Company.  The Company shall work with Huizenga to arrive at rescheduled
dates which are reasonably satisfactory to Huizenga and the Company.  If the
Company desires to reschedule any selected date upon less than thirty days
notice, such rescheduling shall be subject to Huizenga's consent, which consent
shall not be unreasonably withheld or delayed provided such rescheduling is
necessary to permit the Company to schedule an alternative use for the Complex
which would generate significant revenue and if another proximate date is
available and reasonably satisfactory to Huizenga.  No rescheduling of Huizenga
use dates shall be requested by Company within fifteen days of the scheduled
date.
        
             (ii)   Huizenga shall pay all direct costs arising out of his use 
of the Complex.

             (iii)  Huizenga shall comply with all reasonable requirements 
adopted by the Company from time to time relating to the use of the Complex 
including requirements related to facility operations and required insurance 
coverage.

             (iv)   The Company will have the right to approve on an annual 
basis the driving school to be selected by Huizenga, such approval not to be 
unreasonably withheld or delayed.

be terminated and extinguished on the second anniversary of the Closing Date,
except as to particular claims submitted in writing prior to said expiration

contained in paragraph 7.19 which shall continue in effect until the applicable
Statute of Limitations has expired.

representations and warranties of Purchasers herein contained, and the 
respective representations and warranties of the parties herein contained
shall survive the Closing.  All such representations and warranties shall
expire and be terminated and extinguished on the second anniversary of the
Closing Date.

     13. INDEMNIFICATION

     13.1  Indemnification by Sellers.  Each Seller, Sanchez and Huizenga,
severally but not jointly, agrees to indemnify Purchasers and the Company and
hold them harmless from any loss, damage or expense (including reasonable
attorneys' fees) which Purchasers, the Company or any of their officers,
directors, parents or subsidiaries or other affiliates, actually incur (to be
offset by applicable insurance recovery obtained), suffer or become liable for
as a result of or in connection with (a) the inaccuracy or breach of any
agreement, representation or warranty of Sellers, Sanchez or Huizenga contained
in this Agreement, any Exhibit or Schedule to be delivered pursuant hereto
occurring or developing during the period of survival of such agreement,
representation or warranty including any claims by any third parties alleging
facts or circumstances which, if true, would constitute such inaccuracy or
breach; (b) failure to pay any sales or use tax liability of the Sellers for
periods through the Transfer Time; (c) any assertion against the Company or
Purchasers of any claim or liability of Sellers not expressly assumed hereunder
by the Company or Purchasers; (d) unless expressly assumed by the Company or
the Purchasers hereunder, the assertion against the Company or Purchasers by
any person, firm, governmental agency or corporation of any obligation or
liability of Sellers accruing on or prior to, or existing at, the Transfer Time
and thereafter accrued, including without limitation, tax claims or
liabilities; (e) failure of Sellers to obtain necessary consents to assignment
of any of the Transferred Assets to the extent required by this Agreement; or
(f) any and all actions, suits, proceedings, claims, demands, assessments,
judgments, costs and expenses incident to 


                                    -45-
<PAGE>   46

any of the foregoing or in enforcing this indemnity.  Purchasers and the
Company shall give Sellers, Sanchez and Huizenga prompt written notice of any
claim, suit or demand which Purchasers or the Company  believe will give rise
to indemnification by Sellers, Sanchez or Huizenga under this paragraph;
provided, however, that the failure to give such notice shall not affect the
liability of Sellers, Sanchez or Huizenga hereunder unless the failure to give
such notice adversely and materially affects the ability of Sellers, Sanchez or
Huizenga to defend themselves against a claim or to cure the breach or
inaccuracy giving rise to the claim for indemnification on account thereof. 
Except as hereinafter provided, Sellers, Sanchez and Huizenga shall have the
right to defend and to direct the defense against any such claim, suit or
demand, in their names or in the name of Purchasers or the Company at Sellers',
Sanchez's and Huizenga's option and with counsel of Sellers', Sanchez's and
Huizenga's own choosing, which counsel shall be reasonably satisfactory to
Purchasers.  Purchasers and the Company  shall, at Sellers', Sanchez's and
Huizenga's expense, cooperate in the defense of any such claim, suit or demand. 
If Sellers, Sanchez and Huizenga within reasonable time after notice of a
claim, fail to defend Purchasers or the Company or if, in the good faith
judgment of Purchasers, the facts giving rise to indemnification hereunder
shall involve a possible claim by Purchasers or any of their affiliates or the
Company against a third party, or the facts concern a claim constituting or
challenging any material rights or assets of Sellers acquired by the Company
pursuant to this Agreement or seeking an injunction or other equitable relief
against the Company, the Purchasers or any of their affiliates, Purchasers and
the Company shall be entitled to have separate counsel undertake the defense,
compromise or settlement of such claim at the expense of and for the account
and risk of Sellers, Sanchez and Huizenga, subject to the right of Sellers,
Sanchez and Huizenga to assume the defense of such claim at any time prior to
the settlement, compromise or final determination thereof if the only issues
remaining therein involve liability for, or the amount of, money damages to be
assessed against Purchasers or the
        


                                    -46-
<PAGE>   47

Company, provided Sellers, Sanchez and Huizenga will not, without Purchaser's
written consent (not to be unreasonably withheld) settle or compromise any
claim or consent to any entry of judgment which does not include as an
unconditional term thereof the giving by the claimant or the plaintiff to
Purchasers and the Company a release from all liability in respect of such
claim.  No right or remedy conferred in this paragraph is intended to be
exclusive of any other right or remedy available, now or hereafter at law or in
equity or otherwise, to the parties hereto.  Any payments due to Purchasers or
the Company under the terms of this paragraph 13.1 shall be made first from the
escrow account specified in paragraph 6.3 above until the balance in the escrow
account has been exhausted.  Except as specified below, any balance in the
escrow account (including any interest earned thereon) shall be distributed to
Sellers on the first anniversary of the Closing.  In the event that prior to
the first anniversary of the Closing, Purchasers have given notice to Sellers
of an indemnification claim which remains outstanding on the first anniversary
of the Closing, then until such claim is finally resolved, there shall continue
to be held in escrow an amount equal to the amount of the unresolved claim, and
any excess escrow balance shall be distributed to the Sellers on the first
anniversary of the Closing.

     13.2  Indemnification by Purchasers.  Each Purchaser, severally and not
jointly, agrees to indemnify Sellers and hold Sellers harmless from any loss,
damage or expense (including reasonable attorneys' fees) which Sellers actually
incur (to the extent not covered by insurance recoveries obtained), suffer or
become liable for as a result of or in connection with the inaccuracy or breach
of any agreement, representation or warranty of such Purchaser contained in
this Agreement occurring or developing during the period of survival of such
agreement, representation or warranty including any claims by any third party
alleging facts and circumstances which, if true, would constitute such
inaccuracy or breach.  The Company and each Purchaser, severally and not
jointly, agree to indemnify Sellers and hold Sellers harmless from any loss,
damage or expense 


                                    -47-
<PAGE>   48

(including reasonable attorneys' fees) which Sellers actually incur (to the
extent not covered by insurance recoveries obtained), suffer or become liable
for as a result of or in connection with (a) any assertion against Sellers of
any claim or liability of the Company accruing on or after the Closing Date or
arising out of the operation of the Complex after the Closing Date or arising
out of the Company's failure to satisfy the Assumed Obligations; or (b) the
assertion against Sellers by any person, firm, governmental agency or
corporation of any obligation or liability of the Company occurring after the
Closing Date and thereafter occurred, including without limitation, tax claims
or liabilities.  Sellers shall give Purchasers and the Company prompt written
notice of any claim, suit or demand which they believe will give rise to
indemnification under this paragraph; provided, however, that the failure to
give such notice shall not affect the liability of the indemnifying party
hereunder unless the failure to give such notice adversely and materially
affects the ability of the indemnifying party to defend itself against a claim
or to cure the breach or inaccuracy giving rise to the claim for
indemnification on account thereof.  Except as hereinafter provided, the
indemnifying party shall have the right to defend and to direct the defense
against any such claim, suit or demand, in its name or in the names of Sellers
at the indemnifying party's expense and with counsel of the indemnifying
party's own choosing, which counsel shall be reasonably satisfactory to
Sellers.  Sellers shall, at the indemnifying party's expense, cooperate in the
defense of any such claim, suit or demand.  If the indemnifying party, within
reasonable time after notice of a claim, fails to defend Sellers or if, in the
good faith judgment of Sellers, the facts giving rise to indemnification
hereunder shall involve a possible claim by Sellers or any of their affiliates
against a third party seeking an injunction or other equitable relief against
Sellers or any of their affiliates, Sellers shall be entitled to have separate
counsel undertake the defense, compromise or settlement of such claim at the
expense of and for the account and risk of the indemnifying party subject to
the right of the indemnifying party to assume the
        


                                    -48-
<PAGE>   49

defense of such claim at any time prior to the settlement, compromise or final
determination thereof if the only issues remaining therein involve liability
for, or the amount of, money damages to be assessed against Sellers, provided
the indemnifying party will not, without Sellers' written consent (not to be
unreasonably withheld or delayed), settle or compromise any claim or consent to
any entry of judgment which does not include as an unconditional term thereof
the giving by the claimant or the plaintiff to Sellers a release from all
liability in respect of such claim.  No right or remedy conferred in this
paragraph is intended to be exclusive of any other right or remedy available,
now or hereafter at law or in equity or otherwise, to the parties hereto.

     13.3  Maximum Liability.  The aggregate  liability of the Sellers under the
terms of paragraph 13.1 shall not exceed the amount of the Purchase Price
(which amount shall be reduced dollar for dollar for any amounts paid by
Sanchez and Huizenga under paragraph 13.1), and the personal liability of
Sanchez and Huizenga under the terms of paragraph 13.1 shall be limited to
$11,800,000 for each individual; provided, however, that the limitations set
forth in this paragraph 13.3  shall not apply to losses resulting from
intentional fraud or misrepresentation.  The aggregate  liability of the
Company under the terms of Section 13.2 shall not exceed the amount of the
Purchase Price, and the aggregate  liability of each of the Purchasers under
the terms of paragraph 13.2 shall be limited to $11,800,000; provided, however,
that such limitation set forth in this paragraph 13.3  shall not apply to
losses resulting from intentional fraud or misrepresentation.

     13.4  Initial Threshold.  Neither the Sellers, Sanchez and Huizenga under
the terms of paragraph 13.1 nor the Purchasers under the terms of paragraph
13.2 shall be obligated to indemnify any other party except to the extent that
the cumulative amount of all indemnifiable losses exceeds Twenty-Five Thousand
Dollars ($25,000.00) (the "Threshold"), which excess amount shall be
recoverable in accordance with the terms of 


                                    -49-
<PAGE>   50

paragraph 13.1 and paragraph 13.2 above.  The Sellers' allowance for Slow
Accounts specified in paragraph 7.17 shall be in addition to the threshold
amount.
        
     14.  EFFECTIVENESS OF THIS AGREEMENT

     This Agreement shall become effective upon the execution and delivery of
this Agreement (or counterpart thereof) by all parties hereto and shall not be
binding upon any party executing this Agreement (or counterpart thereof) until
executed by all parties hereto.

     15.  BROKERS

     15.1   For Sellers.  Sellers agree, jointly and severally, to indemnify and
hold harmless Purchaser against any claims or liabilities asserted against it
by any person acting or claiming to act as a broker or finder on behalf of
Sellers.

     15.2   For Purchasers.  Purchasers agree to indemnify and hold harmless
Sellers against any claims or liabilities asserted against any of them by any
person acting or claiming to act as a broker or finder on behalf of Purchasers.

     16.  EXPENSES AND ATTORNEY'S FEES

     Except as may otherwise be expressly provided herein, Purchasers on the
one hand and Sellers on the other hand shall pay their own expenses in
connection with this Agreement and the transactions contemplated hereby,
including attorneys' and accountants' fees.  In the event of any dispute
arising under this Agreement, the prevailing party shall be permitted to
recover its attorney's fees.

     17.  SALES, USE, TRANSFER AND OTHER TAXES



                                    -50-
<PAGE>   51


     Sellers and Purchasers shall each pay one half of all sales/use taxes,
transfer taxes of any nature, notarial fees, documentary tax stamps, other
taxes or surtaxes and recording fees incurred in connection with the
consummation or the transactions contemplated hereby specifically including the
transfer of the Homestead Lease to the Company.  Nothing contained herein shall
limit Purchasers' obligations under paragraph 3.3 hereof.

     18. COVENANT NOT TO COMPETE

     Huizenga hereby covenants and agrees that for a period of five (5) years
from and after the Closing Date, he will not, except as permitted below or with
the express written consent of Purchasers, directly or indirectly engage,
participate or invest in or assist, as owner, part-owner, shareholder, partner,
director, trustee, independent contractor, agent or consultant, or in any other
capacity, in any business organization engaged in the business (a "Competitive
Business") of staging or promoting motorsports events or operating a motorsport
facility in any State where ISC or PMI or any of their affiliate operates a
motorsports facility or shall commence to operate a motorsports facility after
the Closing Date; provided, however, that the foregoing restrictions shall not
restrict Huizenga's participation in any competitive enterprise the shares of
which are publically traded through NASDAQ or on a national securities
exchange.

     Huizenga covenants and agrees that for a period of five (5) years from the
Closing Date, he will not, without the express written consent of Purchasers,
hire, or attempt to hire for employment, in any business venture, any person
who was an employee of the Company on the date of termination of such
employee's employment by the Company, or within the two (2) year period
immediately preceeding such date, or attempt to influence any such person to
terminate such employment; or in any other 



                                    -51-
<PAGE>   52

manner interfere with, disrupt or attempt to disrupt the relationship,
contractual or otherwise, between the Company and any of its customers,
suppliers or employees.
        
     In making this undertaking Huizenga understands and agrees that it is of
the essence of this Agreement and that his willingness to make and carry out
this covenant not to compete with the Company for the aforementioned period
stated therein has induced Purchaser to enter into this Agreement.  Without
prejudice to the right of Purchaser or the Company to seek an award for damages
for any breach of this covenant by Huizenga, this covenant shall be
specifically enforceable by way of injunctive relief without the requirement of
posting a bond, which requirement is specifically waived by Huizenga.  It is
the express opinion and intention of the parties hereto that they shall be
bound by the provisions of said covenant not to compete and the parties hereto
each agree that said covenant is reasonable and appropriate in light of the
transaction set forth herein, the consideration being paid therefor and the
purpose of this Agreement.

           (a) Upon written demand made at any time during the period 
commencing on July 1, 2001 and terminating on June 30, 2002, Huizenga shall
have the right, but not the obligation, to require ISC (directly or through its
designee) and PMI (directly or through its designee) to each purchase from him,
or from an entity wholly owned by him, one half of the ten percent (10%)
limited liability company interest in the Company owned by him or an entity
wholly owned by him (the "Huizenga Membership Interest").
        
           (b) If during the period commencing immediately after the Closing 
Date and ending on July 1, 2001, the aggregate  number of Units (as that term 
is defined in the Company's Operating Agreement) transferred by ISC and PMI (or
the ISC Affiliate and the PMI Affiliate) and/or sold by the Company to new

                                    -56-
<PAGE>   57

fifty percent (50%) of the Units outstanding immediately after the Closing, 
Huizenga shall have the right, but not the obligation, to require ISC (directly
or through its designee) and PMI (directly or through its designee) to each 
purchase from him, or an entity wholly owned by him, the Huizenga Membership 
Interest.

          (c) The purchase price for the Huizenga Membership Interest shall be

after the Closing Date by the owner of the Huizenga Membership Interest, and
decreased by the amount of any capital distributed by the Company to the owner
of the Huizenga Membership Interest (other than distributions pursuant to

limited liability company interest in the Company owned by him or an entity
wholly owned by him (the "Sanchez Membership Interest").  The foregoing right
to require the purchase of the Sanchez Membership Interest may be exercised
upon a written demand (the "Sanchez Demand") made (i) at 


                                    -57-
<PAGE>   58

any time during the six month period commencing July 1, 2001, (ii) at any time

Sanchez if he should die prior to July 1, 2005.
        
     (b) If during the period commencing immediately after the Closing Date and
ending on July 1, 2001, the aggregate  number of Units (as that term is defined
in the Operating Agreement) transferred by ISC and PMI (or the ISC Affiliate
and the PMI Affiliate) and/or sold by the Company to new members exceeds fifty
percent (50%) of the Units outstanding immediately after the Closing, Sanchez
shall have the right, but not the obligation, to require ISC (directly or
through its designee) and PMI (directly or through its designee) to each
purchase from him, or an entity wholly owned by him, the Sanchez Membership
Interest.

     (c) The purchase price for the Sanchez Membership Interest shall be the
greater of $2,950,000, increased by the amount of any capital contributed to
the Company after the Closing by or on behalf of the owner of the Sanchez
Membership Interest and decreased by the amount of any capital distributed by
the Company to the owner of the Sanchez Membership Interest (other than
distributions pursuant to Section 7.4 of the Company's Operating Agreement), or
the amount calculated as follows:

         (i)  The Company's regular accountant will calculate the net income of
the Company for its fiscal year immediately preceding or coincident with the
date of the Sanchez Demand increased by the amount of any allocated
administrative overhead charges made by ISC, PMI or their affiliates during
such fiscal year which are in excess of commercially reasonable charges for
similar administrative services and reduced by the amount of federal, state and
local income taxes which would have applied to such income if the Company had
been taxed as a Subchapter C corporation rather than as a limited liability
company taxes as a partnership.  Such adjusted net 
        

                                    -58-
<PAGE>   59

income is hereinafter referred to as the "Adjusted Income."  All calculations
made by the Company's regular accountant shall be made utilizing generally
accepted accounting principals applied in a manner consistent with past
practices for the Company.  Sanchez and his authorized representatives shall
have reasonable access to all the work papers of the accountant which
demonstrate his calculations made in accordance with the terms of this
subparagraph (i).
        
                 (ii)   The Adjusted Income shall be multiplied by the average 
of the earnings multiple at which shares of common stock of ISC and PMI were
being publically traded (on average) during the thirty (30) day period
immediately preceding the Sanchez Demand.  For purposes of calculating earnings
multiple, earnings will be deemed to be the per share earnings reflected on the
annual financial statement for the fiscal year ending prior to the date of the
Sanchez Demand and the daily trading price shall be the "closing price" for
such stock on the principal national securities exchange or the Nasdaq National
Market on which it is traded for a trading day.  The calculation for a company
with more than one class of publically traded common stock, shall be made based
on the most actively publically traded class of common stock for such Company
during the applicable valuation period.  If either ISC or PMI has a $0 or a
negative per share earnings reflected on the applicable financial statement,
then the earnings multiple shall be calculated with reference only to the
corporation with positive per share earnings.
        
                 (iii)  The product obtained after following the procedure 
specified in subparagraph (ii) above shall then be discounted by twenty percent
(20%) and such discounted balance shall be the alternative purchase price for
the Sanchez Membership Interest.
        
     25.3  Call Option for Huizenga Membership Interest.

           (a) Upon written demand made at any time during the period 
commencing July 1, 2002  and ending on the tenth anniversary of such date (the 



                                    -59-
<PAGE>   60

"Huizenga Call Period"), ISC (directly or through its designee) and PMI
(directly or through its designee) shall have the right, but not the
obligation, to require Huizenga to sell or cause one of the Sellers to sell to
each of them one half of the Huizenga Membership Interest at a price equal to
the greater of $2,950,000 adjusted as set forth in paragraph 25.1(c) above or
calculated as set forth below, provided that Huizenga has not exercised his put
right under paragraph 25.1 prior to the date of such demand.  The call may not
be exercised for less than the entire Huizenga Membership Interest.  If during
the Huizenga Call Period, Huizenga desires to sell the Huizenga Membership
Interest in accordance with the terms of Section 8.6 of the Company's Operating
Agreement, then ISC (directly or through its designee) and PMI (directly or
through its designee) shall have thirty (30) days after receipt of the Offer
specified in Section 8.6 of the Company's Operating Agreement to exercise their
call rights specified in this paragraph 25.3; provided however, that if the
call rights are exercised, the purchase price for the Huizenga Membership
Interest shall be the lesser of the amount specified in the Offer or the price
determined as specified in the first sentence of this paragraph 25.3.  If the
call rights are not timely exercised, Huizenga may proceed to sell the Huizenga
Membership Interest strictly in accordance with the terms of the Offer and, if
the sale occurs, no further call rights shall apply to the sold Huizenga
Membership Interest.
        
     (b)  Purchasers and Huizenga shall each within ten (10) days after the
demand specified above select an independent appraiser of national reputation
to make an appraisal of the fair market value of the Huizenga Membership
Interest in accordance with the methodology described below to be completed
within thirty (30) days from the date on which the Purchasers make their
demand.  If a party does not designate an appraiser in a timely manner, an
appraiser shall be selected by the American Arbitration Association.  Each
appraiser in making a fair market value determination shall take into account,
among other things, the income, assets, liabilities, 


                                    -60-
<PAGE>   61

replacement cost of the assets, and the future prospects of the Company.  The
fair market value determination made by any appraiser shall be made as of the
end of the calendar quarter immediately preceding the calendar quarter in which
Purchasers exercise their call option as provided above.  Each Appraiser shall
value the Company as a whole on an ongoing business basis.  The Huizenga
Membership Interest shall then be valued at ten percent (10%) of the Company
valuation and subject to a twenty percent (20%) discount because it is a
minority interest.  No other discount shall apply to the valuation of the
Huizenga Membership Interest under this paragraph 25.3.
        
          (c) If the two fair market value determinations are within a five 
percent (5%) variance of each other, the price of the Huizenga Membership
Interest shall be the average of the two appraisals.  If the two appraisals
vary by more than five percent (5%), the two appraisers shall promptly select a
third appraiser, who shall make an appraisal of the fair market value of the
Huizenga Membership Interest and the price for the Huizenga Membership Interest
shall be the middle valuation of the three appraisals.
        
          (d) The closing of the transaction shall occur on or before sixty (60)
days following the date on which the purchase price has been determined by the
appraisal process set forth above.

     25.4 Call Option for Sanchez Membership Interest.

          (a) Upon written demand made (the "Purchasers' Demand") at any time 
during the "Sanchez Call Period", as that term is hereinafter defined, ISC
(directly or through its designees) and PMI (directly or through its designees)
shall have the right, but not the obligation, to require Sanchez (or his
executor in the event of Sanchez's death) to sell or cause one of the Sellers
to sell to each of them one half of the Sanchez Membership Interest at a price
calculated as set forth below provided that Sanchez has not exercised his put
right under paragraph 25.2 prior to the date of such demand. The call may not
be exercised for less than the entire Sanchez Membership 
        

                                    -61-
<PAGE>   62

Interest. If during the Sanchez Call Period, Sanchez desires to sell the
Sanchez Membership Interest in accordance with the terms of Section 8.6 of the
Company's Operating Agreement, then ISC (directly or through its designee) and
PMI (directly or through its designee) shall have thirty (30) days after
receipt of the Offer specified in Section 8.6 of the Company's Operating
Agreement to exercise their call rights specified in this paragraph 25.4;
provided however, that if the call rights are exercised, the purchase price for
the Sanchez Membership Interest shall be the lesser of the amount specified in
the Offer or the amount determined as specified below in this paragraph 25.4. 
If the call rights are not timely exercised, Sanchez may proceed to sell the
Sanchez Membership Interest strictly in accordance with the terms of the Offer
and, if the sale occurs, no further call rights shall apply to the sold Sanchez
Membership Interest.
        
     (b) The "Sanchez Call Period" shall be (i) the one year period commencing
July 1, 2005, (ii) the period commencing on January 1, 2002 and ending on June
30, 2005 provided that the demand must be made within one year after Sanchez's
employment by the Company is terminated and (iii) one year after the death of
Sanchez if he should die prior to July 1, 2005.

     (c) The purchase price for the Sanchez Membership Interest shall be the
greater of $2,950,000 increased by the amount of any capital contributed to the
Company after the Closing by or on behalf of the owner of the Sanchez
Membership Interest and decreased by the amount of any capital distributed by
the Company to the owner of the Sanchez Membership Interest (other than
distributions pursuant to Section 7.4 of the Company's Operating Agreement) or
the amount calculated as follows:

         (i) The Company's regular accountant will calculate the net income of
the Company for its fiscal year immediately preceding or coincident with the
date of the Purchasers' Demand increased by the amount of any allocated
administrative overhead charges made by ISC, PMI or their affiliates during
such fiscal year which are in excess of commercially reasonable charges for
similar administrative 
        


                                    -62-
<PAGE>   63

services and reduced by the amount of federal, state and local income taxes
which would have applied to such income if the Company had been taxed as a
Subchapter C corporation rather than as a limited liability company taxed as a
partnership.  Such adjusted net income is hereinafter referred to as the
"Adjusted Income." All calculations made by the Company's regular accountant
shall be made utilizing generally accepted accounting principals applied in a
manner consistent with past practices for the Company. Sanchez and his
authorized representatives shall have reasonable access to all the work papers
of the accountant which demonstrate his calculations made in accordance with
the terms of this subparagraph (i).
        
        (ii)  The Adjusted Income shall be multiplied by the average of the
earnings multiple at which shares of common stock of ISC and PMI were being
publically traded (on average) during the thirty (30) day period immediately
preceding the Purchasers' Demand.  For purposes of calculating earnings
multiple, earnings will be deemed to be the per share earnings reflected on the
annual financial statement for the most recent fiscal year ending prior to the
date of the Purchasers' Demand and the daily trading price shall be the
"closing price" for such stock on the principal national securities exchange or
the Nasdaq National Market on which it is traded for a trading day.  The
calculation for a company with more than one class of publically traded common
stock, shall be made based on the most actively publically traded class of
common stock for such company during the applicable valuation period. If either
ISC or PMI has a $0 or a negative per share earnings reflected on the
applicable financial statement, then the earnings multiple shall be calculated
with reference only to the corporation with positive per share earnings.

        (iii) The product obtained after following the procedure specified in
subparagraph (ii) above shall then be discounted by twenty percent (20%) and
such discounted balance shall be the alternative purchase price for the Sanchez
Membership Interest.



                                    -63-

     25.5 Tag Along Rights.  In the event that ISC, or the ISC Affiliate owning
the ISC Interest, and PMI, or the PMI Affiliate owning the PMI Interest, shall
propose to sell in any transaction or series of related transactions at least
eighty percent (80%) of their entire Member Interest (as that term is defined
in the Company's Operating Agreement) then ISC and PMI shall provide written
notice of the proposed sale to all the other Members of the Company and provide
to such other Members the opportunity to sell a proportionate share of their
entire Member Interests at the same price per Member Unit and otherwise on the
same terms and conditions upon which the ISC Interest and the PMI Interest are
to be sold.

     IN WITNESS WHEREOF, the parties hereto have executed or caused this
Agreement to be executed by their duly authorized representatives as of the
date first above written.

                            OPERATING AGREEMENT FOR
                         HOMESTEAD-MIAMI SPEEDWAY, LLC


     THIS OPERATING AGREEMENT (this "Agreement") is made and entered into this
_____________ day of July, 1997, by and among the undersigned parties, as
initial members of the Homestead-Miami Speedway, LLC, a Delaware limited
liability company (the "Company").  The Company was organized as a limited

Title 6, Chapter 18-101 et seq. (the "Act").  Certain defined terms used in
this Agreement are set forth in Schedule I (Schedule of Definitions) attached

                         ALLOCATIONS AND DISTRIBUTIONS

     SECTION 7.1.  ALLOCATION OF NET INCOME, NET LOSS OR CAPITAL GAINS.  Except
as may be expressly provided otherwise in this Article VII, and subject to the
provisions of Sections 704(b) and 704(c) of the Code, the net income, net loss,
or capital gains of the Company for each fiscal year of the Company shall be
allocated to the Members, pro rata in accordance with their respective
Percentage Interests.

     SECTION 7.2.  SPECIAL ALLOCATIONS.  The following special allocations
shall be made in the following order:

     (a) Minimum Gain Chargeback.  Except as otherwise provided in Treasury
Regulation Section 1.704-2(f), notwithstanding any other provision of this
Article VII, if there is a net decrease in Company Minimum Gain during any
fiscal year, each Member shall be specially allocated items of Company income
and gain for such fiscal year (and, if necessary, subsequent fiscal years) in
an amount equal to such Member's share of the net decrease in Company Minimum
Gain, determined in accordance with Treasury Regulation Section 1.704-2(g).
Allocations pursuant to the previous sentence shall be made in proportion to
the respective amounts required to be allocated to each Member pursuant
thereto.  The items to be so allocated shall be determined in accordance with
Treasury Regulation Sections 1.704-2(f)(6) and 1.7042(j)(2).  This Section
7.2(a) is intended to comply with the minimum gain chargeback requirement in
Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently
therewith.

     (b) Member Nonrecourse Debt Minimum Gain Chargeback.  Except as otherwise
provided in Treasury Regulation Section 1.704-2(i)(4), notwithstanding any
other provision of this Article VII, if there is a net decrease in Member
Nonrecourse Debt Minimum Gain attributable to a Member Nonrecourse Debt during
any Fiscal Year, each Member who has a share of the Member Nonrecourse Debt
Minimum Gain attributable to such Member Nonrecourse Debt, determined in
accordance with Treasury Regulation Section 1.704-2(i)(5), shall be
specifically allocated items of Company income and gain for such fiscal year
(and, if necessary, subsequent fiscal years) in an amount equal to such
Member's share of the net decrease in Member Nonrecourse Debt Minimum Gain
attributable to such Member Nonrecourse Debt, determined in accordance with
Treasury Regulation Section 1.704-2(i)(4).  Allocations pursuant to the
previous sentence shall be made in proportion to the respective amounts
required to be allocated to each Member pursuant thereto.  The items to be so



                                     -7-
<PAGE>   79

allocated shall be determined in accordance with Treasury Regulation Sections
1.704-2(i)(4) and 1.704-2(j)(2).  This Section 7.2(b) is intended to comply
with the minimum gain chargeback requirement in Treasury Regulation Section
1.704-2(i)(4) and shall be interpreted consistently therewith.

     (c) Qualified Income Offset.  In the event any Member unexpectedly
receives any adjustments, allocations, or distributions described in Treasury
Regulation Sections 1.7041(b)(2)(ii)(d)(4),1.704-1(b)(2)(ii)(d)(5) or
1.704-l(b)(2)(ii)(d)(6), items of Company income and gain shall be specially
allocated to each such Member in an amount and manner sufficient to eliminate,
to the extent required by the Treasury Regulations, the Adjusted Capital
Account Deficit of such Member as quickly as possible, provided that an
allocation pursuant to this Section 7.2(c) shall be made only if and to the
extent that such Member would have an Adjusted Capital Account Deficit after
all other allocations provided for in this Article VII have been tentatively
made as if this Section 7.2(c) were not in the Agreement.

     (d) Gross Income Allocation.  In the event any Member has a deficit
Capital Account at the end of any fiscal year which is in excess of the sum of
(i) the amount such Member is obligated to restore pursuant to any provision of
this Agreement, and (ii) the amount such Member is deemed to be obligated to
restore pursuant to the penultimate sentences of Treasury Regulation Sections
1.704-2(g)(1) and 1.704-2(i)(5), each such Member shall be specially allocated
items of Company income and gain in the amount of such excess as quickly as
possible, provided that an allocation pursuant to this Section 7.2(d) shall be
made only if and to the extent that such Member would have a deficit Capital
Account in excess of such sum after all other allocations provided for in this
Article VII have been made as if Section 7.2(c) hereof and this Section 7.2(d)
were not in the Agreement.

     (e) Nonrecourse Deductions.  Nonrecourse Deductions for any fiscal year
shall be specifically allocated among the Members in proportion to their
Percentage Interests.

     (f) Member Nonrecourse Deductions.  Any Member Nonrecourse Deductions for
any fiscal year shall be specially allocated to the Member who bears the
economic risk of loss with respect to the Member Nonrecourse Debt to which such
Member Nonrecourse Deductions are attributable in accordance with Treasury
Regulation Section 1.704-2(i)(1).

     (g) Section 754 Adjustments.  To the extent an adjustment to the adjusted
tax basis of any Company asset pursuant to Section 734(b) or Section 743(b) of
the Code is required pursuant to Treasury Regulation Section
1.704-1(b)(2)(iv)(m)(2) or 1.704-l(b)(2)(iv)(m)(4) to be taken into account in
determining Capital Accounts as the result of a distribution to a Member in
complete liquidation of the Member's Interest in the Company, the amount of
such adjustment to Capital Accounts shall be treated as an 



                                     -8-
<PAGE>   80

item of gain (if the adjustment increases the basis of the asset) or loss (if
the adjustment decreases such basis), and such gain or loss shall be specially
allocated to the Members in accordance with their Interests in the Company in
the event Treasury Regulation Section 1.704(b)(2)(iv)(m)(2) applies, or to the
Member to whom such distribution was made in the event Treasury Regulation
Section 1.704-1(b)(2)(iv)(m)(4) applies.
        
     SECTION 7.3.  CURATIVE ALLOCATIONS.  The allocations set forth in Sections
7.2(a) through 7 2(g) hereof (the "Regulatory Allocations") are intended to
comply with certain requirements of the Treasury Regulations.  It is the intent
of the Members that, to the extent possible, all Regulatory Allocations shall
be offset either with other Regulatory Allocations or with special allocations
of other items of Company income, gain, loss or deduction pursuant to this
Section 7.3.  Therefore, notwithstanding any other provision of this Article
VII (other than the Regulatory Allocations), the Members shall make such
offsetting special allocations of Company income, gain, loss, or deduction so
that, after such offsetting allocations are made, each Member's Capital Account
balance is, to the extent possible, equal to the Capital Account balance such
Member would have had if the Regulatory Allocations were not part of the
Agreement and all Company items were allocated pursuant to Section 7.1.

     SECTION 7.4.  DISTRIBUTION OF AVAILABLE CASH.  Subject to Sec.  18-607 of
the Act, within 90 days after the end of each calendar year, Available Cash, if
any, shall be distributed to the Members, pro rata in accordance with their
respective Percentage Interests, in an amount equal to the product of (a) the
Company's taxable income (as determined by the Company's accountant) for such
calendar year, multiplied by (b) the highest combined federal and state
marginal income tax rate applicable to a Member and in effect from time to
time.  Additional distributions may be made at the discretion of a Majority in
Interest of the Members.

     SECTION 7.5.  ALLOCATION OF INCOME AND LOSS AND DISTRIBUTIONS IN RESPECT
OF INTERESTS TRANSFERRED.

     (a) If any Interest is transferred, or is increased or decreased by reason
of the admission of an Additional Member or otherwise, during any fiscal year
of the Company, each item of net income, gain, loss, deduction, or credit of
the Company for such fiscal year shall be assigned pro rata to each day in the
particular period of such fiscal year to which such item is attributable (i.e.,
the day on or during which it is accrued or otherwise incurred), and the amount
of each such item so assigned to any such day shall be allocated to the Member
based upon the Member's respective Percentage Interest at the close of such
day.

     (b) Authorized distributions of Company assets in respect of an Interest
shall be made only to the Members who, according to the books and records of
the Company, are the holders of record of the Interests in respect of which
such distributions are made on the actual date of distribution.  Neither the
Company nor any 


                                     -9-
<PAGE>   81

Member shall incur any liability for making distributions in accordance with the
provisions of the preceding sentence, whether or not the Company or the Member
has knowledge or notice of any transfer or purported transfer of ownership of an
Interest which has not met the requirements of Article VIII.  Notwithstanding
any provision above to the contrary, gain or loss of the Company realized in
connection with a sale or other disposition of any of the assets of the Company
shall be allocated solely to the parties owning Interests as of the date such
sale or other disposition occurs.
        
                                  ARTICLE VIII

             RESTRICTIONS ON WITHDRAWAL AND TRANSFERS OF INTERESTS

     SECTION 8.1.  WITHDRAWAL.  No Member shall withdraw from the Company or
otherwise voluntarily cause an Event of Dissociation as to that Member except
upon not less than sixty (60) calendar days prior written notice to the
remaining Members.  Upon any such withdrawal or other voluntarily caused Event
of Dissociation, the Member shall be an Assignee as to the Member's Units, but
shall not be entitled to have the Member's Interest redeemed or to otherwise
receive any distribution or other payment on account of the Member's withdrawal
or other voluntarily caused Event of Dissociation.  The Company may recover
damages for breach of this Section 8.1 and may offset the Company's damages
against any amount owed to a Member for distributions or otherwise.

     SECTION 8.2.  BASIC RESTRICTIONS ON TRANSFER.  None of the Units
(Interest) of a Member or any portion thereof shall be the subject of a
Transfer, unless the Member has either obtained the prior written consent of a
Majority in Interest of the Members or has fully complied with the provisions
of Section 8.6 and then only in strict accordance with Section 8.6.  Any
Transfer or purported Transfer not in compliance with this Article VIII shall
be null and void.  Except with the prior written consent of all Members, no
Member shall be permitted to transfer less than all of the Member's Interest.

     SECTION 8.3.  FURTHER RESTRICTIONS ON TRANSFER.  In addition to the
restrictions set forth in Section 9.2, no Member shall Transfer all or any part
of the Member's Interest: (a) without registration under applicable state
securities laws, unless an exemption therefrom applies and, if requested by the
Company, the Member delivers an opinion of counsel satisfactory to the Company,
that registration under any such laws is not required; or (b) if the Interest
or portion thereof, when added to the total of all other Interests sold or
exchanged in the preceding 12 consecutive months prior thereto, would result in
the termination of the Company for tax purposes under Section 708 of the Code.

     SECTION 8.4.  STATUS OF TRANSFEREE AND TRANSFEROR.  Notwithstanding
anything contained in this Agreement to the contrary, any transferee or
recipient of a Unit or Units (or any portion thereof) subject to an effective
Transfer shall be an Assignee and 



                                     -10-
<PAGE>   82

shall have no right to (a) vote any Units or portion thereof subject to the
Transfer or to otherwise participate in the management of the business or
affairs of the Company, (b) become a Substitute Member or otherwise exercise any
rights of a Member, or (c) have access to the Company records; unless the
remaining Members, in their sole and absolute discretion approve the admission
of the Assignee as a Substitute Member, and the Assignee executes documentation
satisfactory to the remaining Members accepting and adopting the terms of this
Agreement.  The Assignee shall pay all reasonable expenses of the Company in
connection with his or her admission as a Substitute Member.  The transferor in
a Transfer of the transferor's entire Interest to an Assignee shall cease to be
a Member and shall not have any power to exercise any rights of a Member;
provided, however, that such transferor is not released from any unpaid
contributions or other liability.
        
     SECTION 8.5.  PLEDGE OF INTERESTS.  The pledge or granting of a security
interest, lien or other encumbrance in or against all or any portion of a
Member's Interest shall be a Transfer subject to the restrictions of this
Article VIII; provided, that, in any event, the foreclosure of or exercise of
other secured party remedies with respect to such pledge, security interest,
lien or other encumbrance resulting in a Transfer of any such Interest shall
nonetheless be a Transfer subject to the restrictions of this Article VIII.

     SECTION 8.6.  RIGHT OF FIRST REFUSAL.  Subject to other applicable
restrictions set forth in this Article VIII:

     (a) A Member or Assignee which desires to sell all (but not less than all)
of its Units to a third party ("Transferor") shall first obtain from such third
party a bona fide written offer to purchase all such Units, stating the terms
and conditions upon which the purchase is to be made and the consideration
offered therefor (the "Offer").  The Transferor shall give notice to the
remaining Member of its intention to sell, furnishing a copy of the Offer and
any proposed documentation for the transaction.  No member shall be permitted
to sell less than all its Units except as otherwise permitted by this Agreement
without the consent of a Majority in Interest of the Members.

     (b) The remaining Members (not Assignees), shall have the right to
purchase all (but not less than all) of the Units proposed to be sold upon the
same terms and conditions stated in the Offer, by giving notice to the
Transferor of its intention to do so within 30 days after receiving notice from

provided that such sale is (i) on substantially the same terms as the Offer and
(ii) consummated within 45 days of the expiration of the right of first
refusal.  In the event the remaining Members give written notice to the

allocation of the Units, the remaining Member shall have the right to each
purchase their proportionate share of the Units to be sold.

     A transferee of an Interest shall have the right to become a Substitute
Member only if: (a) the requirements of this Article VIII, specifically
including, but not limited to, Section 8.4, are met, (b) the transferee
executes an instrument satisfactory as determined by the Board of Managers, not
including the transferee, accepting and adopting the terms and provisions of
this Agreement, and (c) the transferee pays any and all expenses in connection

which consummation of the transfer has occurred.  Any transferee of an Interest
in the Company shall take the Interest subject to the restrictions on transfer
imposed by this Agreement.

     SECTION 8.8.  EFFECT OF A VIOLATION.  Any attempted or purported transfer
of a Member's Interest in the Company in violation of this Agreement shall be
void and of no force or effect.

those set forth in Section 8.4.

winding up of the Company to the same extent as any other Member, except that
if the Event of Dissociation is a breach of this Agreement, any distributions
to which the Member would have been entitled shall be reduced by any damages
sustained by the Company as a result of the dissolution and winding up; and

     (b) If the Event of Dissociation does not cause a dissolution and winding
up of the Company under Article X, the Member shall not be entitled to any

the manner, provided under Article X for the dissolution and winding up of the
Company.

                      [DRAFT OPINION OF SELLERS' COUNSEL]


July __, 1997



International Speedway Corporation
1801 West Speedway Boulevard
Daytona Beach, FL  32114-1243

Penske Motorsports, Inc.
13400 Outer Drive, West
Detroit, MI  48239-4001

Gentlemen:

     We have acted as counsel to Miami Motorsports Joint Venture, a Florida
general partnership ("MMJV") and Homestead Motorsports Joint Venture, a Florida
general partnership (HMJV") (MMJV and HMJV jointly referred to as the
"Sellers") and Rafael A. Sanchez ("Sanchez") and Wayne Huizenga ("Huizenga") in
connection with (i) the transfer by Sellers of substantially all their assets
to Homestead-Miami Speedway, LLC  (the "Company") and (ii) the sale by MMJV and
HMJV of limited liability company interests in the Company pursuant to a
Purchase Agreement dated July __, 1997 (the "Agreement") among Sellers, the
Company, International Speedway Corporation ("ISC") and Penske Motorsports,
Inc. ("PMI"), Sanchez and Huizenga.  This opinion is being delivered pursuant
to the Agreement.  All capitalized terms used herein shall, unless otherwise
defined herein, have the meanings set forth in the Agreement.

     For purposes of expressing the opinions set forth below, we have examined
originals, or copies certified to our satisfaction, of all records of the
Sellers and the Company and other agreements, certificates and documents and
have made all such investigations of law as we have deemed relevant and
necessary as the basis for such opinions.

     For the purposes of this opinion, we have assumed, with respect to all
documents examined by us, the accuracy of the matters contained therein, the
genuineness of all signatures, the authenticity of all documents submitted to
us as originals and the conformity to authentic original documents of all
documents submitted to us as certified, conformed, telecopies or photocopied
copies.  We have also relied upon certificates of Sanchez, Huizenga and of
officers of the corporate partners of Sellers with respect to the accuracy of
certain factual matters relevant to the opinions expressed herein.  While we
have not performed any independent verification of such 



<PAGE>   100
                                                                Miami/Homestead 
                                                                July __, 1997
                                                                Page 2



factual matters, other than as set out in this opinion, nothing has come to our
attention during our representation of the Sellers, Sanchez or Huizenga with
respect to the Agreement which leads us to believe that such certificates are
inaccurate.
        
     Based upon the foregoing, we are of the opinion that:

     1.  The Sellers are general partnerships duly organized and  validly 
existing under the laws of the State of Florida.  Each of the Sellers has full
power and authority to own its properties and carry on its business as it is
now being conducted.
        
     2.  The Company is a limited liability company duly organized and  validly
existing under the laws of the State of Delaware.  The Company has full power
and authority to own property and carry on its business as now being conducted.

     3.  Each of the Sellers and the Company has full power and authority to
execute, deliver and perform its obligations under the Agreement.  The
execution and delivery by Sellers and the Company of the Agreement and each of
the other documents and instruments contemplated therein and the performance by
Sellers and the Company of all the transactions contemplated by the Agreement
have been duly authorized by all requisite partnership and limited liability
company action.   Sanchez and Huizenga have duly executed the Agreement in
their individual capacity.

     4.  The Agreement and the documents, agreements and instruments executed
and delivered in connection with the consummation of the transactions
contemplated by the Agreement by Sellers constitute or will constitute the
legal, valid and binding obligations of the Sellers, enforceable in accordance
with their respective terms, except as may be limited by bankruptcy,
insolvency, reorganization or other similar laws affecting the enforcement of
creditors' rights.  The enforceability of the Sellers' obligations under the
agreement is subject to general principles of equity, including without
limitation concepts of materiality, reasonableness, good faith and fair
dealing, and the possible unavailability of specific performance or injunctive
relief, regardless of whether considered in a proceeding in equity or at law.
The Sellers are not parties to any contract or subject to any other legal
restrictions that would prevent or restrict complete fulfillment of any of the
terms and conditions of the Agreement or compliance with their obligations
thereunder.

     5.  Except to the extent disclosed in the Agreement, or in any Schedule
thereto, neither the execution and delivery of the Agreement or the documents,
agreements and instruments executed thereunder nor the performance by Sellers
of the various terms and provisions thereof will violate the partnership
agreement of either of the Sellers or, to our best knowledge, result in a
breach or violation of any term or

                                                                Miami/Homestead
                                                                July __, 1997
                                                                Page 3



provision of, or constitute a default (with or without notice, lapse of time or
the happening or occurrence of any other event) under any material indenture,
lease or any other agreement or instrument to which either of the Sellers is a
party, or by which any of their assets and properties may be bound or affected,
or result in a violation of any law, statute, ordinance, rule, regulation,
order, writ, injunction, decree or award of any court or government authority
or body having jurisdiction over Sellers or of their assets and operations.
        
     6. The Agreement and the documents, agreements and instruments executed
and delivered in connection with the consummation of the transactions
contemplated by the Agreement by the Company constitute or will constitute the
legal, valid and binding obligations of the Company, enforceable in accordance
with their respective terms, except as may be limited by bankruptcy,
insolvency, reorganization or other similar laws affecting the enforcement of
creditors' rights.  The enforceability of the Company's obligations under the
agreement is subject to general principles of equity, including without
limitation concepts of materiality, reasonableness, good faith and fair
dealing, and the possible unavailability of specific performance or injunctive
relief, regardless of whether considered in a proceeding in equity or at law.
The Company is not a party to any contract or subject to any other legal
restrictions that would prevent or restrict complete fulfillment of any of the
terms and conditions of the Agreement or compliance with their obligations
thereunder.

     7. Except to the extent disclosed in the Agreement, or in any Schedule
thereto, neither the execution and delivery of the Agreement or the documents,
agreements and instruments executed thereunder nor the performance by the
Company of the various terms and provisions thereof will violate the
Certificate of Formation or Operating Agreement of the Company or, to our best
knowledge, result in a breach or violation of any term or provision of, or
constitute a default (with or without notice, lapse of time or the happening or
occurrence of any other event) under any material indenture, lease or any other
agreement or instrument to which the Company is a party, or by which any of its
assets and properties may be bound or affected, or result in a violation of any
law, statute, ordinance, rule, regulation, order, writ, injunction, decree or
award of any court or government authority or body having jurisdiction over the
Company or of it assets and operations.

     8. To our knowledge, neither the Sellers nor the Company is in default or
breach under any material contracts, agreements or instruments respecting the
Transferred Assets by which any such entities are bound.

     9. To our knowledge, there is no agreement, contract or undertaking of any
kind or nature which prohibits the Sellers, the Company, Huizenga or Sanchez
from

executing the Agreement or any other documents, instruments or agreements
contemplated thereunder, or from performing any of their obligations
thereunder, except to the extent disclosed in the Agreement, or in any Schedule
thereto.

     10. To our knowledge, there is no action or proceeding pending or
threatened before any court or other governmental body by any person or public
authority seeking to restrain or prohibit, or to obtain damages or other relief
in connection with, the execution and delivery of the Agreement or consummation
of the transaction contemplated thereby.

     11. To our knowledge, except to the extent disclosed in the Agreement or
any Schedule thereto:  (a) neither of the Sellers is a party to or threatened
with, any litigation, suit, action, investigation, proceeding or controversy
before any court, administrative agency or governmental authority which, with
respect to the Transferred Assets, might result in any adverse change in its
licenses, business operations, properties or assets, and (b) neither of the
Sellers is in violation of or in default with respect to any judgment, order,
writ, injunction, decree or rule of any court, administrative agency or
governmental authority or in any material respect under any regulation of any
administrative agency or governmental authority.

     12. To our knowledge, except to the extent disclosed in the Agreement or
any Schedule thereto:  (a) the Company is not a party to or threatened with,
any litigation, suit, action, investigation, proceeding or controversy before
any court, administrative agency or governmental authority which, with respect
to the Transferred Assets, might result in any adverse change in its licenses,
business operations, properties or assets, and (b) the Company is not in
violation of or in default with respect to any judgment, order, writ,
injunction, decree or rule of any court, administrative agency or governmental
authority or in any material respect under any regulation of any administrative
agency or governmental authority.

     13. To our knowledge each of the Sellers and the Company have obtained all
consents, authorizations, orders and approvals of, and filings or registrations
with any governmental commission, board or other regulatory body which are
required for or in connection with the execution and delivery of the Agreement
by the Sellers and the Company and the consummation of the transactions
contemplated thereby by the Sellers and the Company.

     The phrase "to our knowledge", when used herein, means to our actual
knowledge, after due inquiry.

     The opinions expressed herein are based upon the applicable laws, rules
and regulations in effect as of the date hereof, and any change in such laws,
