      SECTION 2. REPRESENTATIONS AND WARRANTIES. In order to induce each Agent
and each Lender to enter into this Tenth Amendment, the Borrowers hereby jointly
and severally represent and warrant to each Agent and each Lender that:

            2.1 ACCURACY OF REPRESENTATIONS AND WARRANTIES. Each of the
representations and warranties of each Borrower contained in the Financing
Documents is true and correct in all material respects as of the date hereof

date).

            2.2 DUE AUTHORIZATION, NO CONFLICTS. The execution, delivery and
performance by the Borrowers of this Tenth Amendment, and all other documents,
instruments or agreements executed by any of the Borrowers in connection with

unlimited liability company, or limited liability company powers, as applicable,
have been duly authorized by all necessary corporate, partnership, unlimited
liability company or limited liability company action, require no action by or
in respect of, or filing with, any governmental body, agency or official and do
not violate or constitute a default under any provision of applicable law or any
material agreement binding upon the Borrowers or their Subsidiaries, or result

            2.3 VALIDITY AND BINDING EFFECT. This Tenth Amendment and all other
documents, instruments or agreements executed by any of the Borrowers in
connection with this Tenth Amendment each constitute the valid and binding
obligations of the applicable Borrowers enforceable in accordance with their

has occurred which is continuing.

            2.5 NO DEFENSE. No Borrower has any defense to payment, counterclaim
or rights of set-off with respect to the Lender Indebtedness on the date hereof.

Borrowers shall deliver to the Administrative Agent amendments to the existing

Documents shall, except as amended and modified hereby, remain in full force and
effect. Each Borrower hereby extends each Lien granted by such Borrower to

Canadian Borrowers) until the Lender Indebtedness (or Canadian Lender
Indebtedness in the case of Canadian Borrowers) has been paid in full, and agree
that the amendments and modifications herein contained shall in no manner affect
or impair the Lender Indebtedness (or Canadian Lender Indebtedness in the use of
Canadian Borrowers) or the Liens securing payment and performance thereof, all
of which are ratified and confirmed.

            4.4 COUNTERPARTS, EFFECTIVENESS OF TENTH AMENDMENT. This Tenth
Amendment may be executed in counterparts, and all parties need not execute the
same counterpart; however, no party shall be bound by this Tenth Amendment until
this Tenth Amendment has been executed by each Borrower and all Lenders, at
which time this Tenth Amendment shall be binding on, enforceable against and
inure to the benefit of the Borrowers, each Agent and all Lenders. Facsimiles
shall be effective as originals.

THE PARTIES.

Lenders or the Agents in exercising, and no course of dealing with respect to,

or any other Financing Document shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, power or privilege under this Tenth
Amendment, the Credit Agreement or any other Financing Document preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.

contained in this Tenth Amendment shall for any reason be held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not affect any other provision hereof, and this Tenth
Amendment shall be construed as if such invalid, illegal, or unenforceable
provision had never been contained herein.

acknowledge, deliver, file and record such further certificates, instruments and
documents, and to do all other acts and things, as may be requested by the

purposes of this Tenth Amendment.

            4.13 WAIVER OF JURY TRIAL. TO THE MAXIMUM EXTENT ALLOWED BY
APPLICABLE LAW, EACH OF THE BORROWERS, THE AGENTS, THE ISSUING BANKS AND THE
LENDERS (I) IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL
ACTION OR PROCEEDING RELATING TO ANY FINANCING DOCUMENT AND FOR ANY COUNTERCLAIM
THEREIN; (II) IRREVOCABLY WAIVE ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY
SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR
DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (III) CERTIFY THAT NO
PARTY HERETO NOR ANY REPRESENTATIVE OR COUNSEL FOR ANY PARTY HERETO HAS
