            (b) Section 2.05 of the Credit Agreement is hereby amended by adding
to the end of such Section new paragraphs (j) and (k) as follows:

                  "(j) Notwithstanding the foregoing, 100% of the proceeds of
                  all Term 1 Loans shall be used to repay Term Loans and the
                  requirements of Sections 2.05(h) and (i) shall not apply to
                  such proceeds and any repayments made with such proceeds.

                  (k) Notwithstanding the foregoing, if the Borrowers make any
                  optional prepayment of Term 1 Loans prior to the one year
                  anniversary of the Amendment No. 1 Effective Date in
                  connection with any Repricing Transaction, the Borrowers shall
                  pay to the Administrative Agent, for the ratable account of
                  each Term 1 Lender, a prepayment premium of 1% of the amount
                  of such Term 1 Loans being prepaid."

            (c) Section 2.06(b) of the Credit Agreement is hereby amended by
adding to the end of such Section new sentence as follows:

                  "The Term 1 Commitment of each Term 1 Loan Lender shall be
                  automatically terminated on the Amendment No. 1 Effective Date
                  upon the Borrowing of the Term 1 Loans on such date."

            (d) Section 6.11 of the Credit Agreement is hereby amended by adding
to the end of such Section a new sentence as follows:

                  "Each of the Borrowers further covenants and agrees that the
                  proceeds of all Term 1 Borrowings hereunder will be used to
                  refinance the existing Term Loans."

            (e) All references to "Term Loan Borrowing," "Term Loan Commitment,"

Lender," "Term 1 Loan Maturity Date" and "Term 1 Loans," respectively (unless
the context otherwise requires).

            (f) The Term 1 Loans made on the Amendment No. 1 Effective Date

            "Repricing Transaction" means the incurrence by any Loan Party of

(to be determined by the Administrative Agent consistent with generally accepted
financial practice) that is less than the Applicable Rate for, or weighted
average yield (to be determined by the Administrative Agent on the same basis)
of, the Term 1 Loans and (ii) the proceeds of which are used to repay, in whole
or in part, principal of outstanding Term 1 Loans.

            "Term 1 Commitment" means, with respect to a Term Lender, the
agreement of such Term Lender to exchange its Term Loans for an equal aggregate
principal amount of Term 1 Loans on the Amendment No. 1 Effective Date, as

            "Term 1 Loan" means an Additional Term 1 Loan or a Loan that is
deemed made pursuant to Section 2.01(c)(i).

            (h) Section 2.01 is hereby amended by adding the following clause

                  "(c)  (i) Subject to the terms and conditions hereof and of
                  Amendment No. 1, each Term Lender with a Term 1 Commitment
                  severally agrees to exchange its Term Loans for a like
                  principal amount in of Term 1 Loans on the Amendment No. 1
                  Effective Date.

                        (ii) Subject to the terms and conditions hereof and of
                  Amendment No. 1, each Additional Term 1 Lender severally
                  agrees to make Additional Term 1 Loans to the Borrowers on the
                  Amendment No. 1 Effective Date in a principal amount not to
                  exceed its Additional Term 1 Commitment on the Amendment No. 1
                  Effective Date. The Borrowers shall prepay all Term Loans of
                  Non-Consenting Term Lenders with the gross proceeds of the
                  Additional Term 1 Loans.

                        (iii) The Borrowers shall pay to the Term Lenders all

                  Amendment No. 1 Effective Date and to the Non-Consenting Term
                  Lenders any breakage loss or expense under Section 3.05. The
                  Amendment No. 1 Effective Date shall be deemed the first day
                  of a new Interest Period with respect to the Term 1 Loans.

                                      -5-

                        (iv) The Term 1 Loans shall have the same terms as the
                  Term Loans as set forth in the Credit Agreement and Loan
                  Documents, except as modified by this Amendment No. 1. For the
                  avoidance of doubt, the Term 1 Loans (and all principal,
                  interest and other amounts in respect thereof) will constitute
                  "Obligations" under the Credit Agreement and the other Loan
                  Documents and shall have the same rights and obligations under
                  the Credit Agreement and Loan Documents as the Term Loans."
