GUARANTY AGREEMENT                                                       PNCBANK

THIS GUARANTY AGREEMENT (this "GUARANTY") is made and entered into as of this
27TH day of January, 2000 by MTR GAMING GROUP, INC. (the "GUARANTOR"), with an
address at State Route 2 South, Chester, West Virginia 26034 in order to induce
PNC LEASING, LLC, a limited liability company (the "LESSOR"), with an address at
Two PlNC Plaza, 13th Floor, 620 Liberty Avenue, Pittsburgh, PA 15222-2719 to
lease to MOUNTAINEER PARK, INC., a West Virginia corporation (the "LESSEE"), the
equipment described in that certain Master Lease Agreement dated on or about the
date hereof, and all schedules and supplements thereto, whether now or hereafter
made a part of said lease (collectively referred to as the "LEASE"), the receipt
and sufficiency of which are hereby acknowledged.

1. GUARANTY OF OBLIGATIONS. The Guarantor hereby guarantees the due and prompt
payment and performance by the Lessee of all rents and other sums due under the
Lease to the Lessor of any kind or nature, present or future (including any
interest accruing thereon after maturity, or after the filing of any petition in
bankruptcy, or the commencement of any insolvency, reorganization or like
proceeding relating to the Lessee, whether or not a claim for post-filing or
post-petition interest is allowed in such proceeding), whether or not for the
payment of money, including reasonable attorneys' fees and expenses (hereinafter
referred to collectively as the "OBLIGATIONS"). If the Lessee defaults under any
such Obligations, the Guarantor will pay the amount due to the Lessor or
otherwise perform the obligations of the Lessee under the Lease.

2. NATURE OF GUARANTY; WAIVERS. This is a guaranty of payment and not of
collection and the Lessor shall not be required, as a condition of the
Guarantor's liability, to make any demand upon or to pursue any of its rights
against the Lessee, or to pursue any rights which may be available to it with
respect to any other person who may be liable for the payment of the
Obligations.

This is an absolute, unconditional, irrevocable and continuing guaranty and will
remain in full force and effect until all of the Obligations have been
indefeasibly paid in full, and/or have been otherwise satisfied. This Guaranty
will remain in full force and effect even if there are no amounts outstanding
under the Obligations at a particular time or from time to time. This Guaranty
will not be affected by any surrender, exchange, acceptance, compromise or
release by the Lessor of any other party, or any other guaranty or any security
held by it for any of the Obligations, by any failure of the Lessor to take any
steps to perfect or maintain its lien or security interest in or to preserve its
rights to any security or other collateral for any of the Obligations or any
guaranty, or by any irregularity, unenforceability or invalidity of any of the
Obligations or any part thereof or any security or other guaranty thereof. The
Guarantor's obligations hereunder shall not be affected, modified or impaired by
any counterclaim, set-off, deduction or defense based upon any claim the
Guarantor may have against the Lessee or the Lessor, except payment or
performance of the Obligations.

Notice of acceptance of this Guaranty, notice of extensions of credit to the
Lessee from time to time, notice of default, diligence, presentment, notice of
dishonor, protest, demand for payment, and any defense based upon the Lessor's
failure to comply with the notice requirements of the applicable version of
Uniform Commercial Code Section 9-504 are hereby waived. The Guarantor waives
all defenses based on impairment of collateral.

The Lessor at any time and from time to time, without notice to or the consent
of the Guarantor, and without impairing or releasing, discharging or modifying
the Guarantor's liabilities hereunder, may (a) change the manner, place, time or
terms of payment or performance of or interest rates on, or other terms relating
to, any of the Obligations; (b) renew, substitute, modify, amend or alter, or
grant consents or waivers relating to any of the Obligations, any other
guaranties, or any security for any Obligations or guaranties; (c) apply any and
all payments by whomever paid or however to any Obligations of the Lessee in
such order, manner and amount as the Lessor may determine in its reasonable
discretion; (d) settle, compromise or deal with any other person, including the
Lessee or the Guarantor, with respect to any Obligations in such manner as the
Lessor deems appropriate in its sole discretion; (e) substitute, exchange or
release any security or guaranty; or (f) take such actions and exercise such
remedies hereunder as provided herein.

3. REPAYMENTS OR RECOVERY FROM THE LESSOR. If any demand is made at any time
upon the Lessor for the repayment or recovery of any amount received by it in
payment or on account of any of the Obligations and if the Lessor repays all or
any part of such amount by reason of any judgment, decree or order of any court
or administrative body or by reason of any settlement or compromise of any such
demand, the Guarantor will be and remain liable hereunder for the amount so
repaid or recovered to the same extent as if such amount had never been received
originally by the Lessor. The provisions of this section will be and remain
effective notwithstanding any contrary action which may have been taken by the
Guarantor in reliance upon such payment, and any such contrary action so taken
will be without prejudice to the Lessor's rights hereunder and will be deemed to
have been conditioned upon such payment having become final and irrevocable.

4. FINANCIAL STATEMENTS. During the term of this Guaranty Agreement and any
extensions or renewals hereof, the Guarantor will furnish to Lessor:

         (a) As soon as practicable following filing with the U.S. Securities
and Exchange Commission (the "SEC") of the Guarantor's required quarterly
reports (including any valid extension of the due date for such reports) the
Guarantor shall provide to Lessor, a balance sheet and statement of income of
the undersigned (the "Financial Statements") as of the close of each of the
first three quarterly period from the beginning of the fiscal year to the date
of such statement, prepared in accordance with

<PAGE>

generally accepted accounting principles, consistently applied, and in such
reasonable detail as Lessor may request, certified as true, complete and correct
by an authorized officer of undersigned;

         (b) As soon as practicable following filing with the SEC of the
Guarantor's required annual report (including any valid extension of the due
date for such report) the Guarantor shall provide to Lessor, a copy of its
annual audited Financial Statements, certified without qualification by an
independent certified public accountant of recognized standing;

         (c) In a timely manner such financial statements, reports and other
information as the Guarantor shall send from time to time to its stockholders
and/or file with the SEC and/or other materials which Lessor shall reasonably
request to the extent that such information is not contained in or supplements
that provided pursuant to subparagraphs (a) and (b) of this paragraph 4.

5. ENFORCEABILITY OF OBLIGATIONS. To the extent permitted by law, no
modification, limitation or discharge of the Obligations arising out of or by
virtue of any bankruptcy, reorganization or similar proceeding for relief of
debtors under federal or state law will affect, modify, limit or discharge the
Guarantor's liability in any manner whatsoever and this Guaranty will remain and
continue in full force and effect and will be enforceable against the Guarantor
to the same extent and with the same force and effect as if any such proceeding
had not been instituted. The Guarantor waives all rights and benefits which
might accrue to it by reason of any such proceeding and will be liable to the
full extent hereunder, irrespective of any modification, limitation or discharge
of the liability of the Lessee that may result from any such proceeding.

6.  EVENTS OF DEFAULT.

         a. The occurrence of any of the following shall be an "EVENT OF
DEFAULT" hereunder:

                  i. any Event of Default as defined in the Lease or herein and
the lapse of any notice or cure period provided with respect to such default;

                  ii. the Guarantor's failure to perform any of its obligations
hereunder;

                  iii. the falsity, inaccuracy or material breach by the
Guarantor of any written warranty, representation or statement made or furnished
to the Lender by or on behalf of the Guarantor; or

                  iv. the termination or attempted termination of this Guaranty.

         b. Upon the occurrence of any uncured Event of Default, which has not
been cured pursuant to the Lease or hereunder, the Guarantor shall pay to the
Lender the outstanding and unpaid amount of the Obligations.

         c. Notwithstanding the foregoing, it is understood and agreed that as a
condition of giving this Guaranty as referenced in paragraph 30(b) of the Lease,
the undersigned shall be given ten (10) days after receipt of written notice
from Lender of a default by Borrower in payment of any Obligations to cure such
default. If the undersigned fails to cure a default by Borrower within ten (10)
days after receipt of written notice from Lender of a default by Borrower, the
undersigned shall immediately become liable for, the balance of the Obligations,
without further notice; PROVIDED HOWEVER, that the Lender in its discretion may
exercise from time to time any other rights and remedies available to it at law,
in equity or otherwise.

7. COSTS. To the extent that the Lessor incurs any reasonable costs or expenses
in protecting or enforcing its rights under the Obligations or this Guaranty,
including reasonable attorneys' fees and the costs and expenses of litigation,
such costs and expenses will be due on demand, will be included in the
Obligations and will bear interest from the incurring or payment thereof at the
Default Rate (as defined in any of the Obligations).

8. POSTPONEMENT OF SUBROGATION. Until the Obligations are indefeasibly paid in
full, the Guarantor postpones and subordinates in favor of the Lessor any and
all rights which the Guarantor may have to (a) assert any claim against the
Lessee based on subrogation rights with respect to payments made hereunder, and
(b) any realization on any property of the Lessee, including participation in
any marshalling of the Lessee's assets.

9. NOTICES. All notices, demands, requests, consents, approvals and other
communications required or permitted hereunder must be in writing and will be
effective upon receipt. Such notices and other communications may be
hand-delivered, sent by facsimile transmission with confirmation of delivery and

10. PRESERVATION OF RIGHTS. No delay or omission on the Lessor's part to
exercise any right or power arising hereunder will impair any such right or
power or be considered a waiver of any such right or power, nor will the
Lessor's action or inaction impair any such right or power. The Lessor's rights
and remedies hereunder are cumulative and not exclusive of any other rights or
remedies which the Lessor may have under other agreements, at law or in equity.
Upon occurrence of an Event of Default, the Lessor may proceed in any order
against the Lessee, the Guarantor or any other obligor of, or collateral
securing, the Obligations, provided that the notice requirements of paragraph 9
are satisfied.

11. ILLEGALITY. In case any one or more of the provisions contained in this
Guaranty should be invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby.

12. CHANGES IN WRITING. No modification, amendment or waiver of any provision of
this Guaranty nor consent to any departure by the Guarantor therefrom will be
effective unless made in a writing signed by the Lessor, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. No notice to or demand on the Guarantor in any case will entitle
the Guarantor to any other or further notice or demand in the same, similar or
other circumstance.

13. ENTIRE AGREEMENT. This Guaranty (including the documents and instruments
referred to herein) constitutes the entire agreement and supersedes all other
prior agreements and understandings, both written and oral, between the

however, that this Guaranty is in addition to, and not in substitution for, any
other guarantees from the Guarantor to the Lessor.

14. SUCCESSORS AND ASSIGNS. This Guaranty will be binding upon and inure to the
benefit of the Guarantor and the Lender and their respective heirs, executors,
administrators, successors and assigns; PROVIDED, HOWEVER, that the Guarantor
may not assign this Guaranty in whole or in part without the prior written
consent of the Lender and neither the Guarantor nor the Lender may assign this
Guaranty in whole or in part without the prior written consent of the West
Virginia Lottery Commission, if required.

15. INTERPRETATION. In this Guaranty, unless the Lessor and the Guarantor
otherwise agree in writing, the singular includes the plural and the plural the
singular; references to statutes are to be construed as including all statutory
provisions consolidating, amending or replacing the statute referred to; the
word "or" shall be deemed to include "and/or", the words "including", "includes"
and "include" shall be deemed to be followed by the words "without limitation";
and references to sections or exhibits are to those of this Guaranty unless
otherwise indicated. Section headings in this Guaranty are included for
convenience of reference only and shall not constitute a part of this Guaranty
for any other purpose.

16. INDEMNITY. The Guarantor agrees to indemnify each of the Lessor, its
directors, officers and employees and each legal entity, if any, who controls
the Lessor (the "INDEMNIFIED PARTIES") and to hold each Indemnified Party
harmless from and against any and all claims, damages, losses, liabilities and
expenses (including all fees and charges of internal or external counsel with
whom any Indemnified Party may consult and all expenses of litigation or
preparation therefor) which any Indemnified Party may incur or which may be
asserted against any Indemnified Party as a result of the execution of or
performance under this Guaranty; PROVIDED, HOWEVER, that the foregoing indemnity
agreement shall not apply to claims, damages, losses, liabilities and expenses
solely attributable to an Indemnified Party's gross negligence or willful
misconduct. The indemnity agreement contained in this Section shall survive the
termination of this Guaranty. The Guarantor may participate at its expense in
the defense of any such claim.

17. GOVERNING LAW AND JURISDICTION. This Guaranty has been delivered to and
accepted by the Lessor and will be deemed to be made in the State of West
Virginia. THIS GUARANTY WILL BE INTERPRETED AND THE RIGHTS AND LIABILITIES OF
THE LESSOR AND THE GUARANTOR DETERMINED IN ACCORDANCE WITH THE LAWS OF THE STATE
OF WEST VIRGINIA, EXCLUDING ITS CONFLICT OF LAWS RULES. The Guarantor hereby
irrevocably consents to the exclusive jurisdiction of any state or federal court
in Allegheny County, Pennsylvania; provided that nothing contained in this
Guaranty will prevent the Lessor from bringing any action, enforcing any award
or judgment or exercising any rights against the Guarantor individually, against
any security or against any property of the Guarantor within any other county,
state or other foreign or domestic jurisdiction. The Guarantor acknowledges and
agrees that the venue provided above is the most convenient forum for both the
Lessor and the Guarantor. The Guarantor waives any objection to venue and any
objection based on a more convenient forum in any action instituted under this
Guaranty.

<PAGE>

support for the Obligations, and (ii) the Guarantor was not required to execute
this Guaranty in violation of Section 202.7(d) of the ECOA.
