contravene any provision of Borrower's or any Guarantor's articles of
incorporation or by-laws, or result in or constitute a Defined Default under any

principles relating to enforceability.

               F. INCORPORATION OF REPRESENTATIONS AND WARRANTIES FROM CREDIT
AGREEMENT. The representations and warranties contained in Section 4 of the
Credit Agreement and in the other Loan Documents are and will be true, correct
and complete in all material respects on and as of the Ninth Amendment Effective

               SECTION 4. ACKNOWLEDGEMENT AND CONSENT

               Guarantors are parties to the Guaranty, the Guarantor Pledge
Agreement (in the case of certain Guarantors), the Security Agreement dated as
of March 31, 1995 and as the same has been and may be amended from time to time

certain Guarantors) and the Second Amended and Restated Trademark Mortgage
Agreement dated as of March 31, 1995 (as amended, the "TRADEMARK AGREEMENT")
between Ticketmaster Corporation and Agent (in the case of Ticketmaster
Corporation) pursuant to which each Guarantor has guarantied the Obligations on
the terms (and to the extent) set forth in the Guaranty and certain Guarantors
have created Liens in favor of Agent on certain Collateral to secure the
Obligations on the terms (and to the extent) set forth in the Guarantor Pledge
Agreement, the Security Agreement and the Trademark Agreement. The Guaranty, the
Guarantor Pledge Agreement, the Security Agreement and the Pledge Agreement are
collectively referred to herein as the "GUARANTOR DOCUMENTS."

               Each Guarantor hereby acknowledges that it has reviewed the terms
and provisions of the Credit Agreement and this Amendment and consents to the
amendment of the Credit Agreement effected pursuant to this Amendment. Each
Guarantor hereby confirms that each Guarantor Document to which it is a party or
otherwise bound and all Collateral encumbered thereby will continue to guaranty
or secure, as the case may be, to the fullest extent 

                                       3

possible in accordance with the applicable provisions of the Guarantor Documents
the payment and performance of all guarantied or secured obligations.

               Each Guarantor acknowledges and agrees that any of the Guarantor
Documents to which it is a party or otherwise bound shall continue in full force
and effect and that all of its obligations thereunder shall be valid and
enforceable and shall not be impaired or limited by the execution or
effectiveness of this Amendment. Each Guarantor represents and warrants that all
representations and warranties contained in the Guarantor Documents to which it
is a party or otherwise bound are true, correct and complete in all material
respects on and as of the Ninth Amendment Effective Date to the same extent as
though made on and as of that date, except to the extent such representations
and warranties specifically relate to an earlier date, in which case they were
true, correct and complete in all material respects on and as of such earlier
date.

               Each Guarantor acknowledges and agrees that (i) notwithstanding
the conditions to effectiveness set forth in this Amendment, such Guarantor is
not required by the terms of the Credit Agreement or any other Loan Document to
consent to the amendments to the Credit Agreement effected pursuant to this
Amendment and (ii) nothing in the Credit Agreement, this Amendment or any other
Loan Document shall be deemed to require the consent of such Guarantor to any
future amendments to the Credit Agreement.


               SECTION 5. MISCELLANEOUS

reference to the Amended Agreement. Except as specifically amended by this
Amendment, the Credit Agreement and the other Loan Documents shall remain in
full force and effect and are hereby ratified and confirmed. The execution,
delivery and performance of this Amendment shall not, except as expressly
provided herein, constitute a waiver of any provision of, or operate as a waiver
of any right, power or remedy of Agent or any Lender under, the Credit Agreement
or any of the other Loan Documents.

               B. FEES AND EXPENSES. Borrower acknowledges that all reasonable
