As used in any other Loan Document, from and after the Restatement Effective Date, all references to the Credit Agreement in such Loan Documents shall, unless the context otherwise requires, mean the Amended and Restated Credit Agreement.




SECTION 2.  Reaffirmation.  Each Reaffirming Party, by its signature below, hereby (a) agrees that, notwithstanding the effectiveness of this Agreement or the Amended and
Restated Credit Agreement, the Security Documents continue to be in full force and effect, (b) affirms and confirms its Guarantee of the Obligations (or, in the case of the Canadian Loan Parties, the Canadian Obligations) and the pledge of and/or grant of a security interest in its assets as Collateral to secure such Obligations, all as provided in the Security Documents as originally executed, and acknowledges and agrees that such Guarantee, pledge and/or grant continue in full force and effect in respect of,
and to secure, such Obligations under the Amended and Restated Credit Agreement and the other Loan Documents and (c) affirms and confirms that all the representations and warranties made by or relating to it contained in the Amended and Restated Credit Agreement and the other Loan Documents are true and correct in all material respects (or in all respects in the case of any representations and warranties qualified by materiality) on and as of the Restatement Effective Date, except to the extent such representations
and warranties expressly relate to an earlier date, in which case they were true and correct in all material respects (or in all respects in the case of any representations and warranties qualified by materiality) as of such earlier date.




SECTION 3.  Representations and Warranties. To induce the other parties hereto to enter into this Agreement, each of Holdings and each Borrower represents and warrants to each of
the other parties hereto, that, at the time of and immediately after giving effect to this Agreement:




(a)  The representations and warranties contained in Article V of the Amended and Restated Credit Agreement and in each other Loan Document are true and correct in all material
respects (or in all respects in the case of any representations and warranties qualified by materiality) on and as of the Restatement Effective Date, except to the extent such representations and warranties expressly relate to an earlier date, in which case they were true and correct in all material respects (or in all respects in the case of any representations and warranties qualified by materiality) as of such earlier date; and




(b)  No Event of Default or Default has occurred and is continuing.

Nothing herein contained shall be construed as a substitution or novation, or a payment and reborrowing, or
a termination, of the Obligations outstanding under the Original Credit Agreement or instruments guaranteeing or securing the same, which shall remain in full force and effect, except as modified hereby or by instruments executed concurrently herewith.  Nothing expressed or implied in this Agreement, the Amended and Restated Credit Agreement or any other document contemplated hereby or thereby shall be construed as a release or other discharge of the Borrowers under the Original Credit Agreement or
the Borrowers or any other Loan Party under any Loan Document from any of its obligations and liabilities thereunder, and such obligations are in all respects continuing with only the terms being modified as provided in this Agreement and in the Amended and Restated Credit Agreement.  The Original Credit Agreement and each of the other Loan Documents shall remain in full force and effect, until and except as modified hereby.  This Agreement shall constitute a Loan Document for all purposes
of the Original Credit Agreement and the Amended and Restated Credit Agreement.




SECTION 6.  Notices.  All notices hereunder shall be given in accordance with the provisions of Section 10.02 of
the Amended and Restated Credit Agreement.




SECTION 7.  Counterparts.  This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an
original but all of which when taken together shall constitute a single contract, and shall become effective as provided in Section 9 hereof.  Delivery of an executed signature page to this Agreement by facsimile transmission shall be effective as delivery of a manually signed counterpart of this Agreement.
