         Second Amendment Effective Date through six months following such date,
         the Leverage Ratio shall be deemed to be not less than 0.75 to 1.00 for
         purposes of determining the Applicable Percentage."

                  (ii) The definition of the term "Lenders" is hereby amended
         and restated in its entirety to read as follows:

                  ""Lenders" shall mean (a) the persons listed on Schedule 2.01
         (other than any such person that has ceased to be a party hereto
         pursuant to an Assignment and Acceptance) and (b) any person that has

         Incremental Assumption Agreement."

                  (iii) The definition of the term "Loan Documents" is hereby
         amended and restated in its entirety to read as follows:

                  ""Loan Documents" shall mean, collectively, this Agreement,
         the Guarantee Agreements, the Security Documents and each Incremental
         Assumption Agreement."

                  (iv) The following definitions are hereby inserted in the
         appropriate alphabetical order:

                  ""Incremental Assumption Agreement" shall mean an Incremental
         Assumption Agreement in form and substance reasonably satisfactory to
         the Administrative Agent, among the U.S. Borrower, the Administrative
         Agent and one or more Incremental Lenders."

                  ""Incremental Commitment" shall mean the commitment of any
         Lender, established pursuant to Section 2.23, to make U.S. Loans to the
         U.S. Borrower."

                  ""Incremental Commitment Amount" shall mean, at any time, the
         excess, if any, of (a) U.S. $25,000,000 over (b) the aggregate amount
         of all Incremental Commitments established prior to such time pursuant
         to Section 2.23."

                  ""Incremental Lender" shall have the meaning assigned to such
         term in Section 2.23."

                  ""Second Amendment Effective Date" shall mean the "Amendment
         Effective Date", as such term is defined in Section 3 of Amendment No.
         2 dated as of December 12, 2002, to this Agreement."

                  (b) Section 2.21(b) of the Credit Agreement is hereby amended
by deleting the figure "U.S. $10,000,000" and substituting in lieu thereof the
figure "U.S. $15,000,000".

                  (c) Article II of the Credit Agreement is hereby amended by
inserting the following Section at the end thereof:

                  "SECTION 2.23. Increase in U.S. Commitments. (a) The U.S.
         Borrower may, by written notice to the Administrative Agent from time
         to time after the Second Amendment Effective Date, request that the
         Total U.S. Commitment be increased by an amount not to exceed the
         Incremental Commitment Amount at such time. Upon the approval of such
         request by the Administrative Agent (which approval shall not be

<PAGE>
                                                                               4

         unreasonably withheld), the Administrative Agent shall deliver a copy
         thereof to each Lender. Such notice shall set forth (a) the amount of
         the requested increase in the Total U.S. Commitment (which shall be in
         minimum increments of U.S. $1,000,000 and a minimum amount of U.S.
         $5,000,000 or equal to the remaining Incremental Commitment Amount) and
         (b) the date on which such increase is requested to become effective
         (which shall not be less than 10 Business Days nor more than 60 days
         after the date of such notice and which, in any event, must be on or
         prior to the Maturity Date), and shall offer each U.S. Lender the
         opportunity to increase its U.S. Commitment by its U.S. Pro Rata
         Percentage of the proposed increase amount. Each U.S. Lender shall, by
         notice to the U.S. Borrower and the Administrative Agent given not more
         than 10 days after the date of the Administrative Agent's notice,
         either agree to increase its U.S. Commitment by all or a portion of the
         offered amount (each Lender so agreeing being an "Increasing Lender")
         or decline to increase its U.S. Commitment (and any Lender that does
         not deliver such a notice within such period of 10 days shall be deemed
         to have declined to increase its U.S. Commitment) (each Lender so
         declining or being deemed to have declined being a "Non-Increasing
         Lender"). In the event that, on the 10th day after the Administrative
         Agent shall have delivered a notice pursuant to the second sentence of
         this paragraph, the U.S. Lenders shall have declined any increase or
         agreed pursuant to the preceding sentence to increase their U.S.
         Commitment by an aggregate amount less than the increase in the Total
         U.S. Commitment requested by the U.S. Borrower, the U.S. Borrower may
         arrange for one or more banks or other entities (any such bank or other
         entity referred to in this clause (a) being called an "Augmenting
         Lender" and, together with the Increasing Lenders, the "Incremental
         Lenders"), to extend the U.S. Commitment in an aggregate amount equal
         to the unsubscribed amount; provided that each Augmenting Lender shall
         be subject to the approval of the Administrative Agent and the Issuing
         Bank (which approvals shall not be unreasonably withheld or delayed).
         Any increase in the Total U.S. Commitment may be made in an amount
         which is less than the increase requested by the U.S. Borrower if the
         U.S. Borrower is unable to arrange for, or chooses not to arrange for,
         Augmenting Lenders.

                  (b) The U.S. Borrower and each Incremental Lender shall
         execute and deliver to the Administrative Agent an Incremental
         Assumption Agreement and such other documentation as the Administrative
         Agent shall reasonably specify to evidence the Incremental Commitment
         of such Incremental Lender or its status as a Lender hereunder. The
         Administrative Agent shall promptly notify each Lender as to the
         effectiveness of each Incremental Assumption Agreement. Each of the
         parties hereto hereby agrees that, upon the effectiveness of any
         Incremental Assumption Agreement, this Agreement shall be deemed
         amended to the extent (but only to the extent) necessary to reflect the
         existence and terms of the Incremental Commitment evidenced thereby.

                  (c) Each of the parties hereto hereby agrees that the
         Administrative Agent may take any and all actions as may be reasonably
         necessary to ensure that, after giving effect to any increase in the
         Total U.S. Commitment pursuant to this Section 2.23, the outstanding
         U.S. Loans (if any) are held by the Lenders in accordance with their
         new U.S. Pro Rata Percentages. This may be accomplished at the
         discretion of the Administrative Agent (i) by requiring the outstanding
         U.S. Loans to be prepaid with the proceeds of a new Borrowing, (ii) by
         causing Non-Increasing Lenders to assign portions of their outstanding
         U.S. Loans to Incremental Lenders, (iii) by permitting the Borrowings
         outstanding at the time of any increase in the Total U.S. Commitment
         pursuant to this Section 2.23 to remain outstanding until the last days
         of the respective

<PAGE>
                                                                               5

Interest Periods therefor, even though the Lenders would hold such Borrowings
other than in accordance with their new U.S. Pro Rata Percentages, or (iv) by
any combination of the foregoing. Any prepayment or assignment described in this
paragraph (c) shall be subject to indemnification by the U.S. Borrower pursuant
to Section 2.15, but otherwise without premium or penalty.

                  (d) Notwithstanding the foregoing, no increase in the Total
         U.S. Commitment (or in the U.S. Commitment of any Lender) or addition
         of a new Lender shall become effective under this Section 2.23 unless,
         (i) on the date of such increase, the conditions set forth in
         paragraphs (b) and (c) of Section 4.01 shall be satisfied and the
         Administrative Agent shall have received a certificate to that effect
         dated such date and executed by a Financial Officer of the U.S.
         Borrower and (ii) the Administrative Agent shall have received (with
         sufficient copies for each of the Lenders) legal opinions, board
         resolutions and an officer's certificate consistent with those
         delivered on the Closing Date under clauses (a)(i) and (c)(ii)(B) of
         Section 4.02."

                  (d) Section 6.04(g) of the Credit Agreement is hereby amended
by deleting the figure "U.S. $5,000,000" and substituting in lieu thereof the
figure "U.S. $10,000,000".

         SECTION 2. Representations and Warranties. To induce the other parties
hereto to enter into this Amendment, the Borrowers represent and warrant to each
of the Lenders, the Administrative Agents, the Issuing Bank and the Collateral
Agents that after giving effect to this Amendment, (a) the representations and
warranties set forth in Article III of the Credit Agreement and each other Loan
Document are true and correct in all material respects on and as of the date

Amendment that, when taken together, bear the signatures of the Borrowers, the
Guarantors and the Required Lenders and (ii) the Amendment Fees (as defined
below) and (b) the Maturity Date shall have been extended to January 25, 2005,
pursuant to Section 2.09(d) of the Credit Agreement.

         SECTION 4. Amendment Fees. The Borrowers agree to pay to each Lender
that executes and delivers a copy of this Amendment to the Administrative Agent
(or its counsel) by 5:00 p.m., New York City time, on November 26, 2002 (the
"Return Date"), an amendment fee (the "Amendment Fee" and, collectively, the
"Amendment Fees") in an amount equal to 0.25% of such Lender's Commitments
(whether used or unused) as of the Return Date. The Amendment Fees shall be
payable in immediately available U.S. dollars on the Amendment Effective Date.
Once paid, the Amendment Fees shall not be refundable.

         SECTION 5. Effect of Amendment. Except as expressly set forth herein,
this Amendment shall not by implication or otherwise limit, impair, constitute a
waiver of, or otherwise affect the rights and remedies of the Lenders, the
Issuing Bank, the Collateral Agents or the Administrative Agents under the
Credit Agreement or any other Loan Document, and shall not alter, modify, amend
or in any way affect any of the terms, conditions, obligations, covenants or
agreements contained in the Credit Agreement or any other Loan Document, all of
which are ratified and affirmed in all respects and shall continue in full force
and effect. Nothing herein shall be deemed to entitle any Loan Party to a
consent to, or a waiver, amendment, modification or other change of, any of the
terms, conditions, obligations, covenants or agreements contained in the Credit
Agreement or any other Loan
