      any Foreign Subsidiary (the Logo Joint Ventures and any such Subsidiary
      being herein collectively called the "Relevant Subsidiaries") shall be
      required to be Subsidiary Guarantors hereunder, provided that in no event
      shall the aggregate EBITDA for any period for all Subsidiaries that are
      not Subsidiary Guarantors exceed 5% of the aggregate EBITDA for such
      period for the Borrower and its Subsidiaries (and, upon such percentage
      being exceeded, the Borrower shall forthwith cause an appropriate number
      of Subsidiaries to become Subsidiary Guarantors hereunder in order that
      such percentage is not exceeded), (y) the Borrower shall cause any

      Indenture and the New Senior Subordinated Notes Indenture that any
      Relevant Subsidiary be released from its Guarantees of the Senior
      Subordinated Notes and the New Senior Subordinated Notes pursuant to the
      Senior Subordinated Notes Indenture and the New Senior Subordinated Notes
      Indenture then, so long as at the time of such request no Default shall
      have occurred and be continuing and the proviso pursuant to clause (x)
      thereof would be satisfied, the Administrative Agent is hereby authorized
      to (and, at the request of the Borrower, shall) release such Relevant
      Subsidiary from its obligations as a Guarantor hereunder and from its
      obligations (if any) as a "Securing Party" under the Security Documents
      (it being understood that the Administrative Agent may condition the
      effectiveness of such release upon the delivery to the trustee under the
      Senior Secured Notes Indenture of the documents required pursuant to
      Section 10.05 thereof to effect the release of such Relevant Subsidiary
      from its Guarantee thereunder)."

            2.07 The portion of Section 7.01(b) of the Credit Agreement
preceding clause (i) of said Section 7.01(b) shall be amended to read as

      Agreements) and (y) Indebtedness under the New Senior Subordinated Notes,
      and any extension, renewal, refunding or replacement of any such
      Indebtedness referred to in the preceding clauses (x) and (y) that does
      not increase the principal amount thereof, provided that any extension,
      renewal, refunding or replacement of the Senior Secured Notes, Senior
      Subordinated Notes or the New Senior Subordinated Notes (the "Refunding
      Indebtedness") shall be permitted, only so long as"

            2.09 Section 7.04(e)(i) of the Credit Agreement shall be amended by
substituting "$100,000,000" for "$50,000,000".

            2.10 Section 7.09(e) of the Credit Agreement shall be amended by

            2.11  Section 7.12 of the Credit Agreement shall be amended to read
as follows:

            "SECTION 7.12.  Modifications of Certain Documents.  The

   5
                                   - 5 -


      Borrower will not, and will not permit any of its Subsidiaries to, consent
      to any modification, supplement or waiver of any of the provisions of any
      documents or agreements evidencing or governing the Senior Secured Notes,
      the Senior Subordinated Notes or the New Senior Subordinated Notes (or any
      Refunding Indebtedness) without the prior consent of the Required Lenders,
      provided that, subject to the last paragraph of Section 6.11(a), the
      Borrower may supplement the Senior Subordinated Notes Indenture or the New
      Senior Subordinated Notes Indenture in order to add or delete Subsidiaries
      as guarantors thereunder as required or permitted by the terms thereof
      without the prior consent of the Required Lenders. Without limiting the
      generality of the foregoing, except for Guarantees by Subsidiaries of the
      Borrower required by the Senior Subordinated Notes Indenture or the New
      Senior Subordinated Notes Indenture, as the case may be, the Borrower will
      not permit any Subsidiary to Guarantee any other Subordinated Indebtedness
      without the prior consent of the Required Lenders."

            Section 3. Representations and Warranties. The Borrower represents
and warrants to the Lenders that the representations and warranties set forth in
Article IV of the Credit Agreement are true and complete on the Effective Date
as if made on and as of the date hereof and as if each reference in said Article
IV to "this Agreement" includes reference to this Amendment No. 2.

amendments to the Credit Agreement set forth in said Section 2 shall become
effective, upon the satisfaction of the following conditions precedent:

            (a) the Administrative Agent shall have received counterparts of
      this Amendment duly executed and delivered by the Borrower, the Subsidiary
      Guarantors, the Required Lenders
      and the Administrative Agent.

            (b) the Borrower shall issue the New Senior Subordinated Notes for
      cash consideration in an aggregate amount not less than $175,000,000
      (before giving effect to deductions for underwriting commissions and
      related transactions expenses), and shall apply the net proceeds of such
      issuance (after giving effect to deductions for underwriting commissions
      and related transactions expenses) first to the prepayment in full of the
      Term Loans and next to the prepayment of the Revolving Credit Loans (it
      being understood and agreed that such

                                   - 6 -


      prepayment shall not result in a reduction of the Revolving Credit
      Commitments).

            Section 5. Miscellaneous. Except as herein provided, the Credit
Agreement shall remain unchanged and in full force and effect.  This Amendment
No. 2 may be executed in any number of counterparts, all of which taken together
shall constitute one and the same amendatory instrument and any of the parties
hereto may execute this Amendment No. 2 by signing any such counterpart.  This
Amendment No. 2 shall be governed by, and construed in accordance with, the law
of the State of New York.

            IN WITNESS WHEREOF, the parties hereto have caused this Amendment
No. 2 to be duly executed and delivered as of the day and year first above
written.
