     WHEREAS, the Borrower, the Lenders and the Agent have entered into that
certain 364-Day Credit Agreement dated as of December 21, 1998 (the "Credit
Agreement");

     WHEREAS, the Borrower seeks to amend the Credit Agreement to extend the
maturity thereof; and

     WHEREAS, the Lenders and the Agent are willing to amend the Credit
Agreement on the terms and conditions herein set forth;

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

     1. Defined Terms. Capitalized terms used herein and not otherwise defined
herein shall have the meanings attributed to such terms in the Credit Agreement.

     2. Amendments to Credit Agreement. Upon the effectiveness of this Amendment
in accordance with the provisions of Section 3 below, the Credit Agreement is
hereby amended as follows:

        (a) Section 1.1 of the Credit Agreement is hereby amended by amending
     the definition of "Commitment" in its entirety to read as follows:

           "Commitment" means, for each Lender, the obligation of such Lender to
     make Loans not exceeding the amount set forth opposite such Lender's name
     on Schedule IV hereto or as set forth in any Notice of Assignment relating
     to any assignment that has become effective pursuant to Section 12.3.2, as
     such amount may be modified from time to time pursuant to the terms hereof.

        (b) Section 1.1 of the Credit Agreement is hereby amended by deleting
     from the definition of "Revolving Credit Termination Date" the date
     "December 20, 1999" and substituting therefor the date "September 2, 2000".











        (c) Section 1.1 of the Credit Agreement is hereby amended by deleting
     from the definition of "Facility Termination Date" the date "December 20,
     2000" and substituting therefor the date "September 2, 2001".

        (d) Section 2.2 of the Credit Agreement is hereby amended by deleting
     from the third sentence thereof the dates "March 20, 2000, June 20, 2000,
     September 20, 2000" and substituting therefor the dates "December 2, 2000,
     March 2, 2001, June 2, 2001".

        (e) The Credit Agreement is amended by adding thereto a new Schedule IV
     in the form attached hereto.

     3. Exiting Lenders.

     3.1 On the Effective Date, the Borrower shall pay to the Agent for the
account of each of the following Lenders (the "Exiting Lenders") all accrued and
unpaid commitment fees to but excluding the Effective Date, all accrued and
unpaid interest on the outstanding Loans of such Exiting Lenders to but
excluding the Effective Date and all amounts owing to such Exiting Lenders
pursuant to Section 3.4 of the Credit Agreement:

     Banca CRT, S.p.A.
     Bank Hapoalim, B.M.
     Bankers Trust Company
     National City Bank of Kentucky

Upon receipt of such amounts from the Borrower, the Agent shall promptly
pay such amounts to the respective Exiting Lenders.

     3.2 As of the Effective Date, the Borrower shall be deemed to have
requested Loans pursuant to the Credit Agreement from only those Lenders whose
Commitments are to be increased pursuant to this Amendment (the "Increasing
Lenders"), the proceeds of which shall be used to repay the principal amount of
the outstanding Loans of the Exiting Lenders as of the Effective Date. The
respective amounts of such requested Loans shall be determined by the Agent such
that, after the making of such Loans by the Increasing Lenders and the repayment
of the Loans of the Exiting Lenders, the outstanding Loans on the Effective Date
shall be held by the Lenders (other than the Exiting Lenders) pro rata in
accordance with their respective Commitments after giving effect to this
Amendment. The Agent shall give each Increasing Lender reasonable notice of the
amount of its respective Loan to be made on the Effective Date, and each
Increasing Lender shall make its Loan available to the Agent prior to 12:00 noon
(Chicago time) on the Effective Date. Upon receipt thereof, the Agent shall
promptly use the proceeds of such Loans to repay the principal amount of the
outstanding Loans of the Exiting Lenders.

     3.3 From and after the Effective Date and upon payment to each Exiting
Lender of all principal of and interest on such Exiting Lender's outstanding
Loans, all commitment fees owing to such Exiting Lender and all funding
indemnification owing to such Exiting Lender in accordance with Section 3.1 and
Section 3.2, each such Exiting Lender











shall not be a Lender under the Credit Agreement, as amended hereby, and
shall be released from all obligations thereunder, whether heretofore or
hereafter arising.

     3.4 On the Effective Date, the Borrower shall pay to the Agent for the
account of each of the Increasing Lenders all amounts owing to such Increasing
Lenders pursuant to Section 3.4 of the Credit Agreement. Upon receipt of such
amounts from the Borrower, the Agent shall promptly pay such amounts to the
respective Increasing Lenders.

     4. Conditions of Effectiveness. This Amendment shall become effective and
be deemed effective as of the date hereof (the "Effective Date") if, and only
if, the Agent shall have received each of the following:

        (a) duly executed originals of this Amendment from the Borrower and each
     of the Lenders; and

        (b) the Reaffirmation attached hereto duly executed on behalf of each of
     the Initial Guarantors and Supplemental Guarantors.

     5. Representations and Warranties of the Borrower. The Borrower represents
and warrants to the Lenders that, as of the Effective Date:

        (a) there exists no Default or Unmatured Default; and

        (b) the representations and warranties contained in Article V of the
     Credit Agreement are true and correct as of the Effective Date except to
     the extent any such representation or warranty is stated to relate solely
     to an earlier date, in which case such representation or warranty was true
     and correct on and as of such earlier date.

     6. Reference to and Effect on the Credit Agreement.

     6.1 Upon the effectiveness of this Amendment pursuant to Section 3 hereof,
on and after the Effective Date each reference in the Credit Agreement to "this
Agreement," "hereunder," "hereof," "herein" or words of like import and each
reference to the Credit Agreement in each Loan Document shall mean and be a

     6.2 Except as specifically waived or amended herein, all of the terms,
conditions and covenants of the Credit Agreement and the other Loan Documents
shall remain in full force and effect and are hereby ratified and confirmed.

     6.3 The execution, delivery and effectiveness of this Amendment shall not,
except as expressly provided herein, operate as a waiver of (a) any right, power
or remedy of any Lender or the Agent under the Credit Agreement or any of the
Loan Documents, or (b) any Default or Unmatured Default under the Credit
Agreement.











     7. CHOICE OF LAW. THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE
INTERNAL LAWS (INCLUDING 735 ILCS 105/5-1 ET SEQ. BUT OTHERWISE WITHOUT REGARD
TO THE CONFLICT OF LAWS PROVISIONS) OF THE STATE OF ILLINOIS, BUT GIVING EFFECT
TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

     8. Counterparts. This Amendment may be executed in any number of
counterparts, each of which when so executed shall be deemed an original and all
of which taken together shall constitute one and the same agreement.

     9. Headings. Section headings in this Amendment are included herein for
convenience of reference only and shall not constitute a part of this Amendment
for any other purpose.

     IN WITNESS WHEREOF, the Borrower, the Agent and the Lenders have executed
