W I T N

N.A. (“BANA”), as Revolving Administrative
Agent, Banc of America Securities LLC, as sole arranger under the Revolving

and Security Agreement, dated as of June 30, 2004, amended as of July 20,
2005, amended and restated as of December 1, 2005, supplemented by the

WHEREAS, in connection with the
Credit Agreement, the Parent, the other Assignors, the LC Facility
Administrative Agent and U.S. Bank National Association, as trustee for the
Second Lien Note Creditors have entered into the Amended and Restated Security
Agreement, dated as of June 30, 2004 and amended and restated as of December 1,
2005 (as the same may be further amended, restated, modified and/or
supplemented from time to time, the “Security Agreement”);
in favor of the LC Facility Administrative Agent for the benefit of the Secured
Parties;

 

WHEREAS, each Additional US
Borrower hereby confirms the grant to the Accounts Collateral Agent of the
security interests in Accounts Collateral for the benefit of itself and each
other Secured Party pursuant to Section 5.1 of the Credit Agreement;

 

WHEREAS, simultaneously
herewith, pursuant to the Security Agreement, the Additional US Borrowers and
the LC Facility Administrative Agent are entering into an Assumption Agreement,
whereby, pursuant to Section 10.13 of the Security Agreement, each
Additional US Borrower is to become an Assignor under the Security Agreement
from and after the date hereof; and

 

 

WHEREAS, this Joinder Agreement
is executed and delivered pursuant to the Credit Agreement;

 

NOW, THEREFORE, IT IS AGREED:

 

1.             Credit Agreement.  (a)  In accordance with Section 9.26
of the Credit Agreement, by executing and delivering this Joinder Agreement,
each Additional US Borrower hereby becomes a US Borrower under the Credit
Agreement from and after the date hereof with the same force and effect as if
originally a “US Borrower” under the Credit Agreement.  Without limiting the generality of the
foregoing, each Additional US Borrower hereby expressly agrees to observe and
perform and be bound by all of the terms, covenants, representations, warranties,
and agreements contained in the Credit Agreement which are binding upon, and to
be observed or performed by, a US Borrower.

 

(b)           Any Secured Party may enforce its rights under the Credit
Agreement independently as to each Credit Party and independently of any other
remedy or security.  Any Secured Party at
any time may have or hold in connection with the Obligations, and it shall not
be necessary for any Secured Party to marshal assets in favor of any Credit
Party or to proceed upon or against or exhaust any security or remedy before proceeding
to enforce the Credit Agreement.  Each
Additional US Borrower expressly waives any right to require any Secured Party
to marshal assets in favor of any Credit Party of the Obligations of such
Additional US Borrower or to proceed against any other US Credit Party, and
agrees that Accounts Collateral Agent may proceed against US Credit Parties or
any US Accounts Collateral in such order as Accounts Collateral Agent shall
determine in its sole and absolute discretion.

 

(c)           Any Secured Party may each file a separate action or actions
against any Credit Party with respect to such Credit Party’s Obligations,
whether such action is brought or prosecuted with respect to any security or
against any guarantor of such Credit Party, or whether any other person is
joined in any such action or actions. 
Each Additional US Borrower agrees that any of the Secured Parties and
any Credit Party and any affiliate of any Credit Party may deal with each other
in connection with the Obligations or otherwise, or alter any contracts or
agreements now or hereafter existing between any of them, in any manner
whatsoever, all without in any way altering or affecting the continuing
efficacy of this Agreement.  Each
Additional US Borrower, as a joint and several Credit Party and guarantor
hereunder with respect to such Additional US Borrower’s Obligations, expressly
waives the benefit of any statute of limitations affecting its joint and
several liability and guarantee hereunder (but not its primary liability) or
the enforcement of the Obligations of such Additional US Borrower or any rights
of any Secured Party created or granted herein.

 

(d)           Each Additional US Borrower acknowledges that the
obligations of such US Credit Party undertaken herein might be construed to
consist, at least in part, of the guarantee of obligations of persons other
than such US Credit Party (including the other US Credit Parties) and, in full
recognition of that fact and in full recognition of the joint and several and
direct and primary liability of each Additional US Borrower hereunder for the
Obligations, each Additional US Borrower consents and agrees that (A) in
the case of the US Revolving Obligations, the Revolving Administrative Agent
and Revolving Lenders, (B) in the case of the Canadian Obligations, the
Canadian Agent and the Canadian Lender and (C) in the case of LC Facility

 

2

 

Obligations, the LC Facility
Administrative Agent, LC Facility Lenders and Term Loan Lenders, may, at any
time and from time to time, without notice or demand (except as provided in and
in accordance with the terms of the Credit Agreement), whether before or after
any actual or purported termination, repudiation or revocation of the Credit
Agreement by any US Credit Party, and without affecting the enforceability or
continuing effectiveness of the Credit Agreement as to each US Credit Party
(including each Additional US Borrower): 
(i) increase, extend, or otherwise change the time for payment or
the terms of the Obligations or any part thereof; (ii) supplement,
restate, modify, amend, increase, decrease, or waive, or enter into or give any
agreement, approval or consent with respect to any of the Obligations or any
part thereof, or any of the Financing Agreements or any additional security or
guarantees, or any condition, covenant, default, remedy, right, representation,
or term thereof or thereunder; (iii) accept new or additional instruments,
documents, or agreements in exchange for or relative to any of the Financing
Agreements or the Obligations or any part thereof; (iv) accept partial
payments on any of the Obligations; (v) receive and hold additional
security or guarantees for the Obligations or any part thereof; (vi) release,
reconvey, terminate, waive, abandon, fail to perfect, subordinate, exchange,
substitute, transfer, or enforce any security or guarantees, and apply any
security and direct the order or manner of sale thereof as such Administrative
Agent in its sole and absolute discretion may determine; (vii) release any
person from any personal liability with respect to the Obligations or any part
thereof; (viii) settle, release on terms satisfactory to such
Administrative Agent or by operation of applicable laws or otherwise liquidate
or enforce any Obligations and any security therefor or guaranty thereof,
respectively, in any manner, consent to the transfer of any security and bid
and purchase at any sale; or (ix) consent to the merger, change, or any
other restructuring or termination of the corporate or partnership existence of
any US Credit Party, and correspondingly restructure the Obligations, and any
such merger, change, restructuring, or termination shall not affect the
liability of any US Credit Party or the continuing effectiveness hereof, or the
enforceability hereof with respect to all or any part of the Obligations.

 

(e)           Each Additional US Borrower (as a Credit Party) expressly
waives any and all defenses now or hereafter arising or asserted by reason of (i) any
disability or other defense of any other Credit Party with respect to such
Credit Party’s Obligations; (ii) the unenforceability or invalidity of any
security or guaranty for such Credit Party’s Obligations or the lack of
perfection or continuing perfection or failure of priority of any security for
such Credit Party’s Obligations; (iii) the cessation for any cause
whatsoever of the liability of such Credit Party (other than by reason of the
full payment and performance of all of such Credit Party’s Obligations); (iv) any
failure of any Secured Party to marshal assets in favor of any Credit Party; (v) any
failure of any Secured Party to give notice to any Credit Party of sale or
other disposition of Collateral of another Credit Party or any defect in any
notice that may be given in connection with any such sale or disposition of
Collateral of any Credit Party securing the Obligations of such Credit Party; (vi) any
failure of any Secured Party to comply with applicable law in connection with
the sale or other disposition of any Collateral or other security of any Credit
Party, for any Obligations of such Credit Party, including any failure of any
Secured Party to conduct a commercially reasonable sale or other disposition of
any Collateral or other security of any other Credit Party for any Obligations
of such Credit Party; (vii) any act or omission of any Secured Party or
others that directly or indirectly results in or aids the discharge or release
of any other Credit Party or any Obligations of any other Credit Party or any
security or guaranty therefor by operation of law or otherwise; (viii) any
law which provides that the

 

3

 

obligation of a surety or
guarantor must neither be larger in amount nor in other respects more
burdensome than that of the principal or which reduces a surety’s or guarantor’s
obligation in proportion to the principal obligation; (ix) any failure of
any Secured Party to file or enforce a claim in any bankruptcy or other
proceeding with respect to any Credit Party; (x) the avoidance of any Lien
or security interest in assets of any other Credit Party in favor of any
Secured Party for any reason; or (xi) any action taken by any Secured Party
that is authorized by this section or any other provision of any Financing
Agreement.  Until such time, if any, as
all of the Obligations of any Additional US Borrower have been indefeasibly
paid and performed in full and no portion of any commitment of any Secured
Party to such Credit Party under any Financing Agreement remains in effect (or
in the case of the Canadian Borrowers, prior to the Discharge of Revolving
Obligations), such Credit Party’s rights of subrogation, contribution,
reimbursement, or indemnity against the other Credit Parties shall be fully and
completely subordinated to the indefeasible repayment in full of all such
Credit Parties’ Obligations, and each Additional US Borrower expressly waives
any right to enforce any remedy that it now has or hereafter may have against
any other Person and waives the benefit of, or any right to participate in, any
Collateral now or hereafter held by any Secured Party.

 

(f)            To the fullest extent permitted
by applicable law, each Additional US Borrower expressly waives and agrees not
to assert, any and all defenses in its favor based upon an election of remedies
by any Secured Party which destroys, diminishes, or affects such Additional US
Borrower’s subrogation rights against the other Credit Parties and/or (except
as explicitly provided for herein) any rights to proceed against each other
Credit Party, or any other party liable to any Secured Party, for
reimbursement, contribution, indemnity, or otherwise.

 

(g)           Each Additional US Borrower warrants and agrees that each of
the waivers and consents set forth herein are made after consultation with
legal counsel and with full knowledge of their significance and consequences,
with the understanding that events giving rise to any defense or right waived
may diminish, destroy, or otherwise adversely affect rights which such
Additional US Borrower otherwise may have against the other Credit Parties or
the Secured Parties, or others, or against the Collateral, and that, under the
circumstances, the waivers and consents herein given are reasonable.  If any of the waivers or consents herein are
determined to be contrary to any applicable law or public policy, such waivers
and consents shall be limited to the extent required in order to be enforceable
under applicable law.

 

(h)           The foregoing affirmations and covenants of each Additional
US Borrower are in addition to, and not in lieu of, those set forth in the
Credit Agreement, including, without limitation, Section 14 thereof.

 

2.             Effect on the Credit Agreement.  On and after the effectiveness of this
Joinder Agreement, each reference in the Credit Agreement and the other
Financing Agreements to the “US Borrowers,” or words to that effect shall mean
and be a reference to the Parent, each of the Credit Parties signatory to the
Credit Agreement and each Additional US Borrower for all purposes of the Credit
Agreement and each Financing Agreement.

 

3.             Grant of Security Interests in
Accounts Collateral.  To secure payment and performance of all
Obligations, each Additional US Borrower hereby confirms the grant to the
Accounts Collateral Agent for the benefit of itself and each other Secured
Party pursuant to

 

4

 

Section 5 of the Credit
Agreement and in furtherance thereof hereby grants, subject to the terms and
conditions of such Section 5, to the Accounts Collateral Agent for the
benefit of itself and each other Secured Party, a continuing security interest
in, a Lien upon, and a right of set off against, all right, title and interest
of such Additional US Borrower in all of the Accounts Collateral, whether now
owned or hereafter acquired or existing, and wherever located.

 

4.             Governing Law; Choice of Forum;
Service of Process; Jury Trial Waiver.  The validity,
interpretation and enforcement of this Joinder Agreement and the other
Financing Agreements (except as otherwise expressly provided therein) and any
dispute arising out of the relationship between the parties hereto, whether in
contract, tort, equity or otherwise, shall be governed by the internal laws of
The State of New York (without giving effect to principles of conflicts of
law).

 

Each Additional US Borrower and
each Administrative Agent irrevocably consents and submits to the nonexclusive
jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New
York, and any appellate court from any thereof, whichever the Administrative
Agents may elect, and in addition, each Additional US Borrower irrevocably
consents and submits to the nonexclusive jurisdiction of the Ontario Superior
Court of Justice, in each case, whichever the Administrative Agents may elect
and waive any objection based on venue or forum non conveniens with respect to
any action instituted therein arising under this Joinder Agreement or any of
the other Financing Agreements or in any way connected with or related or
incidental to the dealings of the parties hereto in respect of this Joinder
Agreement or any of the other Financing Agreements or the transactions related
hereto or thereto, in each case whether now existing or hereafter arising, and
whether in contract, tort, equity or otherwise, and agree that any dispute with
respect to any such matters shall be heard only in the courts described above
(except that Accounts Collateral Agent (with respect to the Accounts
Collateral) and LC Facility Collateral Agent (with respect to the Non-Accounts
Collateral) and Lenders shall have the right to bring any action or proceeding
against any Credit Party or its property in the courts of any other
jurisdiction which such Collateral Agent deems necessary or appropriate in
order to realize on the applicable Collateral or to otherwise enforce its
rights against any Credit Party or its property).

 

Each Additional US Borrower
hereby waives personal service of any and all process upon it and consents that
all such service of process may be made by certified mail (return receipt
requested) directed to its address set forth herein and service so made shall
be deemed to be completed five (5) days after the same shall have been so
deposited in the US mails, or, at an Administrative Agent’s option, by service
upon such Additional US Borrower in any other manner provided under the rules of
any such courts.  Within thirty (30) days
after such service, Additional US Borrowers shall appear in answer to such
process, failing which such Additional US Borrower shall be deemed in default
and judgment may be entered by Lender against such Additional US Borrower for
the amount of the claim and other relief requested.

 

EACH ADDITIONAL US BORROWER AND
EACH ADMINISTRATIVE AGENT HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY
CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS JOINDER
AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR (ii) IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO

 

5

 

IN RESPECT OF THIS AGREEMENT OR
ANY OF THE OTHER FINANCING AGREEMENTS OR THE TRANSACTIONS RELATED HERETO OR
THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN

EACH ADDITIONAL US BORROWER AND EACH ADMINISTRATIVE AGENT EACH HEREBY
AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION
SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT ANY CREDIT PARTY OR ANY
LENDER MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS JOINDER
AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

 

5.             Financing Agreement. 
This Joinder Agreement shall constitute a Financing Agreement.

IN WITNESS WHEREOF, each of the
undersigned has caused this Joinder Agreement to be duly executed and delivered
as of the date first above written.
