     SECTION 3.4.  Manner of Payment.  Each payment (including repayments

interest on the Loans or of any fee, commission or other amounts payable to the

(Charlotte time) on the date specified for payment under this Agreement to the
Lender at the Lender's Office, in Dollars, in immediately available funds and
shall be made without any set-off, counterclaim or deduction whatsoever.  Any
payment received after such time but before 5:00 p.m. (Charlotte time) on such

shall be deemed to have been made on the next succeeding Business Day for all

such extension of time shall in such case be included in computing any interest
if payable along with such payment.

     SECTION 3.5.  Changed Circumstances.

     (a) Circumstances Affecting Eurodollar Rate Availability.  If with respect
to any Interest Period for a Eurodollar Loan, the Lender shall reasonably
determine that, by reason of circumstances affecting the foreign exchange and
interbank markets generally, 

                                     20

<PAGE>   26

deposits in eurodollars in the applicable amounts are not being offered
to the Lender for such Interest Period, then the Lender shall forthwith give
notice thereof to the Borrower.  Thereafter, until the Lender notifies the
Borrower that such circumstances no longer exist, the obligation of the Lender
to make Eurodollar Loans and the right of the Borrower to convert any Loan to 
or continue any Loan as a Eurodollar Loan shall be suspended, and the Borrower
shall repay in full (or cause to be repaid in full) the then outstanding
principal amount of each such Eurodollar Loan together with accrued interest
thereon, on the last day of the then current Interest Period applicable to such
Eurodollar Loan or convert the then outstanding principal amount of each such
Eurodollar Loan to a Base Rate Loan as of the last day of such Interest Period.

     (b) Laws Affecting Eurodollar Rate Availability.  If, after the date
hereof, the introduction of, or any change in, any Applicable Law or any change
in the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Lender with any request or
directive (whether or not having the force of law) of any such Governmental
Authority, central bank or comparable agency, shall make it unlawful or
impossible for the Lender to honor its obligations hereunder to make or
maintain any Eurodollar Loan, the Lender shall promptly give notice thereof to
the Borrower.  Thereafter, until the Lender notifies the Borrower that such
circumstances no longer exist, (i) the obligation of the Lender to make
Eurodollar Loans and the obligation of the Lender to convert any Eurodollar
Loan made by the Lender or continue any such Eurodollar Loan as a Eurodollar
Loan shall be suspended, (ii) each Eurodollar Loan made by the Lender shall be
converted to a Base Rate Loan upon the last day of the then current Interest
Period applicable thereto (or immediately upon demand by the Lender, if
required by Applicable Law) and (iii) thereafter, the Lender shall make only
Base Rate Loans (including upon any request by the Borrower for Eurodollar
Loans) hereunder.

     (c) Increased Costs.  If, after the date hereof, the introduction of, or
any change in, any Applicable Law, or in the interpretation or administration
thereof by any Governmental Authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by the
Lender with any request or directive (whether or not having the force of law)
of such Governmental Authority, central bank or comparable agency:



                                     21

<PAGE>   27


     (i) shall subject the Lender to any tax, duty or other charge with respect
to the Note or shall change the basis of taxation of payments to the Lender of
the principal of or interest on the Note or any other amounts due under this
Agreement in respect thereof (except for changes in the rate of tax on the net
income of the Lender imposed by the jurisdiction in which the Lender is
organized or is or should be qualified to do business or the Lender's Office is
located); or

     (ii) shall impose, modify or deem applicable any reserve (including,
without limitation, any imposed by the Board of Governors of the Federal
Reserve System but excluding any reserve included in the Adjusted Eurodollar
Rate Reserve Percentage), special deposit, insurance or capital or similar
requirement against assets of, deposits with or for the account of, or credit
extended by the Lender or shall impose on the Lender or the foreign exchange
and interbank markets any other condition affecting the Note;

and the result of any of the foregoing is to increase the costs to the Lender
of maintaining any Eurodollar Loan or to reduce the yield or amount of any sum
received or receivable by the Lender under this Agreement or under the Note in
respect of a Eurodollar Loan then the Lender shall promptly notify the Borrower
of such fact and demand compensation therefore and, within fifteen (15) days
after such notice by the Lender, the Borrower shall pay to the Lender such
additional amount or amounts as will compensate the Lender for such increased
cost or reduction.  The Lender will promptly notify the Borrower of any event
of which it has knowledge which will entitle it to compensation pursuant to
this Section 3.5(c); provided, that the Lender shall incur no liability
whatsoever to the Borrower in the event it fails to do so.  A certificate of
the Lender setting forth the basis for determining such amount or amounts
necessary to compensate the Lender shall be forwarded to the Borrower and shall
be conclusively presumed to be correct absent manifest error.

     SECTION 3.6.  Indemnity.  The Borrower hereby indemnifies the Lender
against any loss or expense which may result directly and primarily from the
Lender's obtaining, liquidating or employing deposits or other funds acquired
to effect, fund or maintain any Loan (a) as a consequence of any failure by the
Borrower to make any payment when due in connection with a Eurodollar Loan, (b)
due to any failure of the Borrower to borrow on a date specified therefore in a
Notice of Borrowing, Notice of Conversion/Continuation or (c) due to any
payment, prepayment or conversion of any Eurodollar Loan on a date other than
the last day of the 

                                     22

<PAGE>   28

Interest Period therefore. A certificate of the Lender setting forth the
basis for determining such amount or amounts necessary to compensate the Lender
shall be forwarded to the Borrower and shall be conclusively presumed to be
correct absent manifest error.

     SECTION 3.7.  Capital Requirements.  If either (a) the introduction of, or
any change in, or in the interpretation of, any Applicable Law or (b)
compliance with any guideline or request from any central bank or comparable
agency or other Governmental Authority (whether or not having the force of
law), has or would have the effect of reducing the rate of return on the
capital of, or has affected or would affect the amount of capital required to
be maintained by, the Lender or any corporation controlling the Lender as a
consequence of, or with reference to the Commitment of any Lender and other
commitments of this type, below the rate which the Lender or such other
corporation could have achieved but for such introduction, change or
compliance, then within five (5) Business Days after written demand by the
Lender, the Borrower shall pay to the Lender from time to time as specified by
the Lender additional amounts sufficient to compensate the Lender or other
corporation for such reduction.  A certificate as to such amounts submitted to
the Borrower by the Lender, shall be conclusively presumed to be correct absent
manifest error.

     SECTION 3.8.  Taxes.

     (a) Payments Free and Clear.  Any and all payments by the Borrower
hereunder or under the Note shall be made free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholding, and all liabilities with respect thereto excluding
income and franchise taxes imposed by the jurisdiction under the laws of which
the Lender is organized or is or should be qualified to do business or any
political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes").  If the Borrower shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under the Note to the Lender, (A)
the sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 3.8) the Lender receives an amount equal to the amount it
would have received had no such deductions been made, (B) the Borrower shall
make such deductions, (C) the Borrower shall pay the full amount deducted to
the relevant taxing authority or other authority in accordance with applicable
law and (D) the Borrower shall deliver to the 

                                     23

<PAGE>   29

Lender evidence of such payment to the relevant taxing authority or
other authority in the manner provided in Section 3.8(d).

     (b) Stamp and Other Taxes.  In addition, the Borrower shall pay any
present or future stamp, registration, recordation or documentary taxes or any
other similar fees or charges or excise or property taxes, levies of the United
States or any state or political subdivision thereof or any applicable foreign
jurisdiction which arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, the
Loans, the other Loan Documents, or the perfection of any rights or security
interest in respect thereto (hereinafter referred to as "Other Taxes").

     (c) Indemnity.  The Borrower shall indemnify the Lender for the full
amount of Taxes and Other Taxes (including, without limitation, any Taxes and
Other Taxes imposed by any jurisdiction on amounts payable under this Section
3.8) paid by the Lender and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted.  Such indemnification shall
be made within thirty (30) days from the date the Lender makes written demand
therefore.

     (d) Evidence of Payment.  Within thirty (30) days after the date of any
payment of Taxes or Other Taxes, the Borrower shall furnish to the Lender, at
the Lender's Office, the original or a certified copy of a receipt evidencing
payment thereof or other evidence of payment satisfactory to the Lender.

     (e) Survival.  Without prejudice to the survival of any other agreement of
the Borrower hereunder, the agreements and obligations of the Borrower
contained in this Section 3.8 shall survive the payment in full of the
Obligations and the termination of the Credit Facility.

capital stock of the Subsidiaries have been duly authorized and validly issued
and are fully paid and nonassessable.  Each of the Subsidiaries of the Borrower
listed on Schedule 5.1(b) is Wholly-Owned by the Borrower.  As of the date

to which it is a party in accordance with their respective terms.  This
Agreement and each of the other Loan Documents have been duly executed and
delivered by the duly authorized officers of the Borrower and each of its

enforcement of creditors' rights in general and the availability of equitable
remedies.

     (d) Compliance of Agreement, Loan Documents and Borrowing with Laws,
Etc. The execution, delivery and performance by the Borrower and its
Subsidiaries of the Loan Documents to which each such Person is a party, in
accordance with their respective terms, the borrowings hereunder and the
transactions contemplated hereby do not and will not, by the passage of time,
the giving of notice or otherwise, (i) require any Governmental Approval or
violate any Applicable Law relating to the Borrower or any of its Subsidiaries,
(ii) conflict with, result in a breach of or constitute a default under the
articles of incorporation, bylaws or other organizational documents of the
Borrower or any of its Subsidiaries or any material indenture, agreement or

properties may be bound or any Governmental Approval relating to such Person or
(iii) result in or require the creation or imposition of any Lien upon or with
respect to any property now owned or hereafter acquired by such Person other

                                     29

<PAGE>   35

     (e) Compliance with Law; Governmental Approvals.  Each of the Borrower and
its Subsidiaries (i) has all Governmental Approvals required by any Applicable

is final and not subject to review on appeal and is not the subject of any
pending or, to the best of its knowledge, threatened attack by direct or
collateral proceeding and (ii) is in compliance with each Governmental Approval
applicable to it and all other Applicable Laws relating to it or any of its
respective properties, except in each case under clause (i) and (ii) above to
the extent that (A) such requirement or compliance is contested in good faith
by appropriate proceedings or (B) the failure to do so could not reasonably be
expected to have a Material Adverse Effect.

has duly filed or caused to be filed all federal, state, local and other tax
returns required by Applicable Law to be filed, and has paid, or made adequate
provision for the payment of, all federal, state, local and other taxes,
assessments and governmental charges or levies upon it and its property,
income, profits and assets which are due and payable, except for any such taxes
or charges being contested in good faith by appropriate proceedings.  No
Governmental Authority has asserted any Lien or other claim against the
Borrower or any Subsidiary thereof with respect to unpaid taxes which has not
been discharged or resolved.  The charges, accruals and reserves on the books
of the Borrower or any of its Subsidiaries in respect of federal, state, local
and other taxes are in the judgment of the Borrower adequate, and the
Borrower does not anticipate any material additional taxes or assessments for
any year or portion thereof.

Subsidiaries owns or possesses all lawful rights to use all franchises,
licenses, patents, patent rights or licenses, patent applications, copyrights,
copyright applications, trademarks, trademark rights, trade names, trade name
rights and rights with respect to the foregoing which are necessary in any
material respect to conduct its business.  To the knowledge of the Borrower, no
event has occurred which permits, or after notice or lapse of time or both
would permit, the revocation or termination of any such rights, and neither the
Borrower nor any Subsidiary thereof is liable to any Person for infringement
under Applicable Law with respect to any such rights as a result of its
business operations.

engaged principally or as one of its activities in the business of extending
credit for the purpose of "purchasing" or "carrying" any "margin stock" (as
each such term is defined or used in Regulations G and U of the Board of
Governors of the Federal Reserve System). No part of the proceeds of any of the
Loans will be used for purchasing or carrying margin stock or for any purpose
which violates, or which would be inconsistent with, the provisions of
Regulation G, T, U or X of such Board of Governors.

     (k) Government Regulation.  Neither the Borrower nor any Subsidiary
thereof is an "investment company" or a company "controlled" by an "investment
company" (as each such term is defined or used in the Investment Company Act of
1940, as amended) and neither the Borrower nor any Subsidiary thereof is, or
after giving effect to any Loan will be, subject to regulation under the Public
Utility Holding Company Act of 1935 or the Interstate Commerce Act, each as
amended, or any other Applicable Law which limits its ability to incur or
consummate the transactions contemplated hereby.

     (l) Employee Relations.  Each of the Borrower and its Subsidiaries has a
stable work force in place and is not, except as set forth on Schedule 5.1(l),
party to any collective bargaining agreement nor has any labor union been
recognized as the representative of its employees.  The Borrower knows of no
pending, threatened or contemplated strikes, work stoppage or 

                                     33

<PAGE>   39

other collective labor disputes involving its employees or those of its
Subsidiaries.

     (m) Financial Statements.  The audited Consolidated balance sheet of the
Borrower and its Subsidiaries as of December 31, 1995, and the related
statements of income and retained earnings and cash flows for the Fiscal Year
then ended and unaudited Consolidated balance sheet of the Borrower and its
Subsidiaries as of March 31, 1996, and related unaudited interim statements of
income and retained earnings and cash flows for the fiscal period then ended,
copies of which have been furnished to the Lender, fairly present in all
material respects the assets, liabilities and financial position of the
Borrower and its Subsidiaries as at such dates, and the results of the
operations and changes of financial position for the periods then ended.  All
such financial statements, including the related schedules and notes thereto,
have been prepared in accordance with GAAP except as may be otherwise disclosed
therein or in the notes thereto (subject in the case of the interim statements
to year-end audit adjustments).  As of the date hereof, the Borrower and its
Subsidiaries have no Debt, obligation or other unusual forward or long-term
commitment which is not fairly reflected in the foregoing financial statements
or in the notes thereto.

     (n) Solvency.  As of the Closing Date and after giving effect to each Loan
made hereunder, the Borrower and its Subsidiaries, taken as a whole, will be
Solvent.

     (o) Titles to Properties.  Each of the Borrower and its Subsidiaries has
such title to the real property owned by it as is necessary to the conduct of
its business and valid and legal title to all of its personal property and
assets reflected on the balance sheets of the Borrower and its Subsidiaries
described in Section 5.1(m) or in any financial statements hereafter delivered
pursuant to Section 6.1, except such assets which have been disposed of by the
Borrower or its Subsidiaries subsequent to such date in the ordinary course of
business or as otherwise expressly permitted hereunder.

     (p) Debt and Liens.  Schedule 5.1(p) is a complete and correct list, as of
the date hereof, of each item of Debt of the Borrower and its Subsidiaries in
excess of $100,000 and each Lien securing such Debt, each of which is permitted
under the terms of Sections 9.1 and 9.2, respectively.  The Borrower and its
Subsidiaries have performed and are in compliance with all of the
terms of such Debt and Liens and all instruments and agreements relating
thereto, and no default or event of default, or event or 

                                     34

<PAGE>   40

condition which with notice or lapse of time or both would constitute
such a default or event of default on the part of the Borrower or its
Subsidiaries exists with respect to any such Debt or Liens.  None of the
properties and assets of the Borrower or any Subsidiary thereof is subject to
any Lien, except for Permitted Liens.

     (q) Litigation.  Except as set forth on Schedule 5.1(q), there are no
actions, suits or proceedings pending nor, to the best knowledge of the
Borrower, threatened against or in any other way relating adversely to or
affecting the Borrower or any Subsidiary thereof or any of their respective
properties in any court or before any arbitrator of any kind or before or by
any Governmental Authority, that, if adversely determined, might reasonably be
expected to have a Material Adverse Effect.

     (r) Absence of Defaults.  No event has occurred or is continuing which
constitutes a Default or an Event of Default, or which constitutes, or which
with the passage of time or giving of notice or both would constitute, a
default or event of default by the Borrower or any Subsidiary thereof under any
judgment, decree or order by which the Borrower or its Subsidiaries or any of
their respective properties may be bound or which would require the Borrower or
its Subsidiaries to make any payment thereunder prior to the scheduled maturity
date therefore.

     (s) Accuracy and Completeness of Information.  All written information,
reports and other papers and data produced by or on behalf of the Borrower or
any Subsidiary thereof and furnished to the Lender were, at the time the same
were so furnished and taken as a whole, true and correct in all material
respects to the extent necessary to give the recipient a true and accurate
knowledge of the subject matter.  The documents and other written information
furnished or written statements made to the Lender by the Borrower or any
Subsidiary thereof in connection with the negotiation, preparation or execution
of this Agreement or any of the Loan Documents, taken as a whole, do not
contain any untrue statement of a material fact or omit to state a fact
necessary in order to make the statements contained therein not materially
misleading.  The Borrower is not aware of any facts which it has not disclosed
in writing to the Lender which have a Material Adverse Effect, or insofar as
the Borrower can now foresee, could reasonably be expected to have a Material
Adverse Effect.

     (t) Burdensome Provisions.  Neither the Borrower nor any of its
Subsidiaries is a party to any indenture, agreement, lease or other instrument,
or subject to any corporate or partnership 

                                     35

<PAGE>   41

restriction, Governmental Approval or Applicable Law which is so
unusual or burdensome as in the foreseeable future could be reasonably expected
to have a Material Adverse Effect.  The Borrower and its Subsidiaries do not
presently anticipate that future expenditures needed to meet the provisions of
any statutes, orders, rules or regulations of a Governmental Authority will be
so burdensome as to have a Material Adverse Effect.

     (u) Insurance.  The properties of the Borrower and its Subsidiaries are
insured with financially sound and reputable insurance companies in such
amounts, with such deductibles and covering such risks as are customarily
carried by companies engaged in similar businesses and owning similar
properties in localities where the Borrower and its Subsidiaries operate.

     (v) No Material Adverse Change.  Since December 31, 1995, there has been
no material adverse change in the business, condition (financial or otherwise),
operations or properties of the Borrower and its Subsidiaries, taken as a
whole, or any event, condition or state of facts that will or could be
reasonably expected to have a Material Adverse Effect.

     SECTION 5.2.  Survival of Representations and Warranties, Etc.  All
representations and warranties set forth in this Article V and all
representations and warranties contained in any certificate, or any of the Loan
Documents (including but not limited to any such representation or warranty
made in or in connection with any amendment thereto) shall constitute
representations and warranties made under this Agreement.  All representations
and warranties made under this Agreement shall be made or deemed to be made at
and as of the Closing Date, shall survive the Closing Date and shall not be
waived by the execution and delivery of this Agreement, any investigation made
by or on behalf of the Lender or any borrowing hereunder.

                  Credit Agreement dated as of July __, 1996,

                           Penske Motorsports, Inc.,
                                      and
                               NationsBank, N.A.


                              SUBSIDIARY GUARANTY


     THIS UNCONDITIONAL GUARANTY AGREEMENT (this "Guaranty"), dated as of the
______ day of July, 1996 made by _____________________, a ___________
corporation (the "Guarantor"), in favor of NATIONSBANK, N.A., a national
banking association ("Lender"), under the Credit Agreement of even date
herewith between PENSKE MOTORSPORTS, INC., a Delaware corporation, as Borrower
(the "Borrower"), and Lender (as amended or supplemented, the "Credit
Agreement").

                              STATEMENT OF PURPOSE

     Pursuant to the terms of the Credit Agreement, the Lender has agreed to
extend a revolving line of credit to the Borrower in the aggregate principal
amount of up to Twenty Million Dollars ($20,000,000).  The Borrower, the
Guarantor and each other  Subsidiary comprise one integrated financial
enterprise, and all Loans to the Borrower will inure directly or indirectly, to
the benefit of the Guarantor.

     In connection with the transactions contemplated by the Credit Agreement,
the Lender has requested, and the Guarantor has agreed to execute and deliver,
this Guaranty.

     NOW, thereforeE, in consideration of the premises and the  mutual
agreements set forth herein, and to induce the Lender to continue to make
available Loans pursuant to the Credit Agreement, it is agreed as follows:

     1. Definitions.  Capitalized terms used herein (including the preamble
hereof) shall have the meanings assigned to them in the Credit Agreement,
unless the context otherwise requires or unless otherwise defined herein.
References in the Credit Agreement to a "Subsidiary Guaranty" or herein to this
"Guaranty" shall include and mean this Guaranty, including all amendments and
supplements hereto now or hereafter in effect.


<PAGE>   82

     2. Guaranty of Obligations of Borrower.  The Guarantor hereby
unconditionally guarantees to the Lender, and its respective successors,
endorsees, transferees and assigns, the prompt payment and performance of all
Obligations of the Borrower, whether primary or secondary (whether by way of
endorsement or otherwise), whether now existing or hereafter arising, whether or
not from time to time reduced or extinguished (except by payment thereof) or
hereafter increased or incurred, whether or not recovery may be or hereafter
become barred by the statute of limitations, whether enforceable or
unenforceable as against the Borrower, whether or not discharged, stayed or
otherwise affected by any bankruptcy, insolvency or other similar law or
proceeding, whether created directly with the Lender or acquired by the Lender
through assignment, endorsement or otherwise, whether matured or unmatured,
whether joint or several, as and when the same become due and payable (whether
at maturity or earlier, by reason of acceleration, mandatory repayment or
otherwise), in accordance with the terms of any such instruments evidencing any
such obligations, including all renewals, extensions or modifications thereof
(all Obligations of the Borrower to the Lender, including all of the foregoing,
being hereinafter collectively referred to as the "Guaranteed Obligations");
provided, that notwithstanding anything to the contrary contained herein, it is
the intention of the Guarantor and the Lender that, in any proceeding involving
the bankruptcy, reorganization, arrangement, adjustment of debts, relief of
debtors, dissolution or insolvency or any similar proceeding with respect to the
Guarantor or its assets, the amount of the Guarantor's obligations with respect
to the Guaranteed Obligations shall be in, but not in excess of, the maximum
amount thereof not subject to avoidance or recovery by operation of applicable
law governing bankruptcy, reorganization, arrangement, adjustment of debts,
relief of debtors, dissolution, insolvency, fraudulent transfers or conveyances
or other similar laws (including, without limitation, 11 U.S.C. Section 547,
Section 548, Section 550 and other "avoidance" provisions of Title 11 of the
United States Code) applicable in any such proceeding to the Guarantor and this
Guaranty (collectively, "Applicable Insolvency Laws").  To that end, but only in
the event and to the extent that the Guarantor's obligations with respect to the
Guaranteed Obligations or any payment made pursuant to the Guaranteed
Obligations would, but for the operation of the foregoing proviso, be subject to
avoidance or recovery in any such proceeding under Applicable Insolvency Laws,
the amount of the Guarantor's obligations with respect to the Guaranteed
Obligations shall be limited to the largest amount which, after giving effect
thereto, would not, under Applicable Insolvency Laws, render the Guarantor's
obligations with respect 


<PAGE>   83

to such Guaranteed Obligations unenforceable or avoidable or otherwise
subject to recovery under Applicable Insolvency Laws.  To the extent any payment
actually made pursuant to the Guaranteed Obligations exceeds the limitation of
the foregoing proviso and is otherwise subject to avoidance and recovery in any
such proceeding under Applicable Insolvency Laws, the amount subject to
avoidance shall in all events be limited to the amount by which such actual
payment exceeds such limitation and the Guaranteed Obligations as limited by the
foregoing proviso shall in all events remain in full force and effect and be
fully enforceable against the Guarantor.  The foregoing proviso is intended
solely to preserve the rights of the Lender hereunder against the Guarantor in
such proceeding to the maximum extent permitted by Applicable Insolvency Laws
and neither the Guarantor, the Borrower, any other guarantor under the Credit
Agreement nor any other Person shall have any right or claim under such proviso
that would not otherwise be available under Applicable Insolvency Laws in such
proceeding. 

      3. Nature of Guaranty.  The Guarantor agrees that this Guaranty is a
continuing, unconditional guaranty of payment and performance and not of
collection, and that its obligations under this Guaranty shall be primary,
absolute and unconditional, irrespective of, and unaffected by:

           (a) the genuineness, validity, regularity, enforceability or any
      future amendment of, or change in, the Credit Agreement or any other Loan
      Document or any other agreement, document or instrument to which the 
      Borrower or any Subsidiary thereof is or may become a party;

           (b) the absence of any action to enforce this Guaranty, the Credit
      Agreement or any other Loan Document or the waiver or consent by the
      Lender with respect to any of the provisions of this Guaranty, the Credit
      Agreement or any other Loan Document;

           (c) the existence, value or condition of, or failure to perfect its
      Lien against, any security for or other guaranty of the Guaranteed
      Obligations or any action, or the absence of any action, by the Lender in
      respect of such security or guaranty (including, without limitation, the
      release of any such security or guaranty); or



<PAGE>   84

           (d) any other action or circumstances which might otherwise
      constitute a legal or equitable discharge or defense of a surety or
      guarantor;

it being agreed by the Guarantor that, subject to the proviso in Section 2      
hereof, its obligations under this Guaranty shall not be discharged until the
final and indefeasible payment and performance, in full, of the Guaranteed
Obligations and the termination of the Commitment.  To the extent permitted by
law, the Guarantor expressly waives all rights it may now or in the future have
under any statute (including without limitation North Carolina General Statutes
Section 26-7, et seq. or similar law), or at law or in equity, or otherwise, to
compel the Lender to proceed in respect of the Guaranteed Obligations against
the Borrower or any other party or against any security for or other guaranty of
the payment and performance of the Guaranteed Obligations before proceeding
against, or as a condition to proceeding against, the Guarantor.  To the extent
permitted by law, the Guarantor further expressly waives and agrees not to
assert or take advantage of any defense based upon the failure of the Lender to
commence an action in respect of the Guaranteed Obligations against the
Borrower, the Guarantor, any other guarantor or any other party or any security
for the payment and performance of the Guaranteed Obligations.  The Guarantor
agrees that any notice or directive given at any time to the Lender which is
inconsistent with the waivers in the preceding two sentences shall be null and
void and may be ignored by the Lender, and, in addition, may not be pleaded or
introduced as evidence in any litigation relating to this Guaranty for the
reason that such pleading or introduction would be at variance with the written
terms of this Guaranty, unless the Lender has specifically agreed otherwise in
writing.  The foregoing waivers are of the essence of the transaction
contemplated by the Loan Documents and, but for this Guaranty and such waivers,
the Lender would decline to enter into the Credit Agreement.

     4. Demand by the Lender.  In addition to the terms set forth in Section 3,
and in no manner imposing any limitation on such terms, if all or any portion
of the then outstanding Guaranteed Obligations under the Credit Agreement are
declared to be immediately due and payable, then the Guarantor shall, upon
demand in writing therefore by the Lender to the Guarantor, pay all or such
portion of the outstanding Guaranteed Obligations then declared due and
payable.  Payment by the Guarantor shall be made to the Lender, to be credited
and applied upon the Guaranteed Obligations, in immediately available Dollars
to an account designated by the Lender or at the address referenced herein for




<PAGE>   85

the giving of notice to the Lender or at any other address that may be
specified in writing from time to time by the Lender.

     5. Waivers.  In addition to the waivers contained in Section 3, the
Guarantor, to the extent permitted by law, waives and agrees that it shall not
at any time insist upon, plead or in any manner whatever claim or take the
benefit or advantage of, any appraisal, valuation, stay, extension, marshalling
of assets or redemption laws, or exemption, whether now or at any time
hereafter in force, which may delay, prevent or otherwise affect the
performance by the Guarantor of its obligations under, or the enforcement by
the Lender of, this Guaranty.  The Guarantor further hereby waives diligence,
presentment, demand, protest and notice of whatever kind or nature with respect
to any of the Guaranteed Obligations and waives the benefit of all provisions
of law which are or might be in conflict with the terms of this Guaranty.  The
Guarantor represents, warrants and agrees that its obligations under this
Guaranty are not and shall not be subject to any counterclaims, offsets or
defenses of any kind against the Lender or the Borrower whether now existing or
which may arise in the future.

     6. Benefits of Guaranty.  The provisions of this Guaranty are for the
benefit of the Lender and its respective successors, transferees, endorsees and
assigns, and nothing herein contained shall impair, as between the Borrower and
the Lender, the obligations of the Borrower under the Loan Documents.  In the
event all or any part of the Guaranteed Obligations are transferred, endorsed
or assigned by the Lender to any Person or Persons, any reference to "Lender"
herein shall be deemed to refer equally to such Person or Persons.

     7. Modification of Loan Documents, etc.  If the Lender shall at any time or
from time to time, with or without the consent of, or notice to, the Guarantor:

           (a) change or extend the manner, place or terms of payment of, or
      renew or alter all or any portion of, the Guaranteed Obligations;

           (b) take any action under or in respect of the Loan Documents in the
      exercise of any remedy, power or privilege contained therein or available
      to it at law, in equity or otherwise, or waive or refrain from exercising
      any such remedies, powers or privileges;



<PAGE>   86

           (c) amend or modify, in any manner whatsoever, the Loan Documents;

           (d) extend or waive the time for performance by the Guarantor, any
      other guarantor, the Borrower or any other Person of, or compliance with,
      any term, covenant or agreement on its part to be performed or observed
      under a Loan Document (other than this Guaranty), or waive such
      performance or compliance or consent to a failure of, or departure from,
      such performance or compliance;

           (e) take and hold security or collateral for the payment of the
      Guaranteed Obligations or sell, exchange, release, dispose of, or
      otherwise deal with, any property pledged, mortgaged or conveyed, or in
      which the Lender has been granted a Lien, to secure any Debt of the
      Guarantor, any other guarantor or the Borrower to the Lender;

           (f) release anyone who may be liable in any manner for the payment
      of any amounts owed by the Guarantor, any other guarantor or the Borrower
      to the Lender;

           (g) modify or terminate the terms of any intercreditor or
      subordination agreement pursuant to which claims of other creditors of
      the Guarantor, any other guarantor or the Borrower are subordinated to
      the claims of the Lender; or

           (h) apply any sums by whomever paid or however realized to any
      amounts owing by the Guarantor, any other guarantor or the Borrower to
      the Lender in such manner as the Lender shall determine in its reasonable
      discretion;

then the Lender shall incur no liability to the Guarantor as a result thereof,
and no such action shall impair or release the obligations of the Guarantor
under this Guaranty.

     8. Reinstatement.  The Guarantor agrees that, if any payment made by the
Borrower or any other Person applied to the Obligations is at any time
annulled, set aside, rescinded, invalidated, declared to be fraudulent or
preferential or otherwise required to be refunded or repaid or the proceeds of
any collateral are required to be refunded by the Lender to the Borrower, its
estate, trustee, receiver or any other party, including, without limitation,
the Guarantor, under any Applicable Law or equitable cause, then, to the extent
of such payment or 


<PAGE>   87

repayment, the Guarantor's liability hereunder (and any Lien securing such
liability) shall be and remain in full force and effect, as fully as if such
payment had never been made, and, if prior thereto, this Guaranty shall have
been canceled or surrendered (and if any Lien or collateral securing the
Guarantor's liability hereunder shall have been released or terminated by virtue
of such cancellation or surrender), this Guaranty (and such Lien) shall be
reinstated in full force and effect, and such prior cancellation or surrender
shall not diminish, release, discharge, impair or otherwise affect the
obligations of the Guarantor in respect of the amount of such payment (or any
Lien securing such obligation).

     9. Representations and Warranties.  To induce the Lender to make any
Loans, the Guarantor hereby represents and warrants that:

           (a) the Guarantor has the corporate right, power and authority to
      execute, deliver and perform this Guaranty and has taken all necessary
      corporate action to authorize its execution, delivery and performance of,
      this Guaranty;

           (b) this Guaranty constitutes the legal, valid and binding
      obligation of the Guarantor enforceable in accordance with its terms,
      except as enforceability may be limited by bankruptcy, insolvency,
      reorganization, moratorium or similar laws affecting the enforcement of
      creditors' rights generally and by the availability of equitable
      remedies;

           (c) the execution, delivery and performance of this Guaranty will
      not violate any provision of any Applicable Law or material contractual
      obligation of the Guarantor and will not result in the creation or
      imposition of any Lien upon or with respect to any property or revenues

the Lender to seek a deficiency judgment against the Borrower shall not impair
the Guarantor's obligation to pay the full amount of the Guaranteed Obligations.

     (i) Waiver of Jury Trial.  TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE

Obligations or any of them; provided, that the Guarantor shall not be obligated
to reimburse the Lender for costs and expenses, or indemnify the Lender for any
loss, resulting from the gross negligence or willful misconduct of the Lender.

Lender is entitled under this Guaranty shall continue in full force and effect

III. Championship Auto Racing Teams, Inc., et al v. Anton Hulman George,
     Indianapolis Motor Speedway Corporation, et al. U.S. District Court,
     Eastern District of Michigan, Case No. 96-71301.

        Penske Motorsports, Inc. ("PMI") is a party plaintiff in Action III,
and a party defendant in Actions I and II, arising out of the dispute among
CART and Tony George relating to the conduct of Indy car racing. In substance,
the George Group (which includes Foyt) is alleged to be engaged in an unlawful
attempt to destabilize CART by, among other things, leveraging the Indianapolis
500 race participation to participation in less attractive IRL races. The
George Group has alleged that CART teams have boycotted the Indianapolis 500
race to eliminate the IRL as a competitor.

        The Michigan court has reaffirmed that the case must be tried in
Detroit notwithstanding an Indiana court ruling that the anti-trust issues be
tried in Indianapolis. The alleged misconduct of PMI has not been specified,
nor the damages.
