Page #PageNum#


or nonpayment of any such liabilities, suit or taking of other action by the Administrative Agent or any other Secured Creditor against, and any other notice to, any party liable thereon (including such Guarantor, any other Guarantor, any other guarantor, any Canadian Borrower or any other Guaranteed Party) and each Guarantor further hereby waives any and all notice of the creation, renewal, extension or accrual of any of the Guaranteed Obligations and notice or proof of reliance by any Secured Creditor upon this Canadian Guaranty, and the Guaranteed Obligations shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended, modified, supplemented or waived, in reliance upon this Canadian Guaranty.
(b)    Each Guarantor waives any right (except as shall be required by applicable statute and cannot be waived) to require the Secured Creditors to:  (i) proceed against any Canadian Borrower, any other Guaranteed Party, any other Guarantor, any other guarantor of the Guaranteed Obligations or any other party; (ii) proceed against or exhaust any security held from any Canadian Borrower, any other Guaranteed Party, any other Guarantor, any other guarantor of the Guaranteed Obligations or any other party; or (iii) pursue any other remedy in the Secured Creditors’ power whatsoever.  Each Guarantor waives any defense based on or arising out of any defense of any Canadian Borrower, any other Guaranteed Party, any other Guarantor, any other guarantor of the Guaranteed Obligations or any other party other than the occurrence of the Termination Date, including, without limitation, any defense based on or arising out of the disability of any Canadian Borrower, any other Guaranteed Party, any other Guarantor, any other guarantor of the Guaranteed Obligations or any other party, or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any Canadian Borrower or any other Guaranteed Party other than the occurrence of the Termination Date.

Each Guarantor waives any defense arising out of any such election by the Secured Creditors, even though such election may operate to impair or extinguish any right of reimbursement, contribution, indemnification or subrogation or other right or remedy of such Guarantor against any Canadian Borrower, any other Guaranteed Party, any other guarantor of the Guaranteed Obligations or any other party or any security.
(c)    Each Guarantor has knowledge and assumes all responsibility for being and keeping itself informed of each Canadian Borrower’s, each other Guaranteed Party’s and each other Guarantor’s financial condition, affairs and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks which such Guarantor assumes and incurs hereunder, and has adequate means to obtain from each Canadian Borrower, each other Guaranteed Party and each other Guarantor on an ongoing basis information relating thereto and each Canadian Borrower’s, each other Guaranteed Party’s and each other Guarantor’s ability to pay and perform its respective Guaranteed Obligations, and agrees to assume the responsibility to keep so informed for so long as such Guarantor is a party to this Canadian Guaranty.  Each Guarantor acknowledges and agrees that (x) the Secured 





Page #PageNum#


Creditors shall have no obligation to investigate the financial condition or affairs of any Canadian Borrower, any other Guaranteed Party or any other Guarantor for the benefit of such Guarantor nor to advise such Guarantor of any fact respecting, or any change in, the financial condition, assets or affairs of any Canadian Borrower, any other Guaranteed Party or any other Guarantor that might become known to any Secured Creditor at any time, whether or not such Secured Creditor knows or believes or has reason to know or believe that any such fact or change is unknown to such Guarantor, or might (or does) increase the risk of such Guarantor as guarantor hereunder, or might (or would) affect the willingness of such Guarantor to continue as a Guarantor hereunder and (y) the Secured Creditors shall have no duty to advise any Guarantor of information known to them regarding any of the aforementioned circumstances or risks.
(d)    Each Guarantor hereby acknowledges and agrees that no Secured Creditor nor any other Person shall be under any obligation (a) to marshal any assets in favor of such Guarantor or in payment of any or all of the liabilities of any Guaranteed Party under the Secured Debt Agreements or the obligation of such Guarantor hereunder or (b) to pursue any other remedy that such Guarantor may or may not be able to pursue itself any right to which such Guarantor hereby waives.
(e)    Each Guarantor warrants and agrees that each of the waivers set forth in Section 3 hereof and in this Section 4 is made with full knowledge of its significance and consequences and that if any of such waivers are determined to be contrary to any applicable law or public policy, such waivers shall be effective only to the maximum extent permitted by applicable law.


5.    RIGHTS OF SECURED CREDITORS.  Any Secured Creditor may (except as shall be required by applicable statute and cannot be waived) at any time and from time to time without the consent of, or notice to, any Guarantor, without incurring responsibility to such Guarantor, without impairing or releasing the obligations or liabilities of such Guarantor hereunder, upon or without any terms or conditions and in whole or in part:
(a)    change the manner, place or terms of payment of, and/or change, increase or extend the time of payment of, renew, increase, accelerate or alter, any of the Guaranteed Obligations (including, without limitation, any increase or decrease in the rate of interest thereon or the principal amount thereof), any security therefor, or any liability incurred directly or indirectly in respect thereof, and the guaranty herein made shall apply to the Guaranteed Obligations as so changed, extended, increased, accelerated, renewed or altered;

(e)    settle or compromise any of the Guaranteed Obligations, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of any Canadian Borrower or any other Guaranteed Party to creditors of any Canadian Borrower or such other Guaranteed Party other than the Secured Creditors;
(f)    apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of any Canadian Borrower or any other Guaranteed Party to the Secured Creditors regardless of what liabilities of such Canadian Borrower or such other Guaranteed Party remain unpaid;
(g)    consent to or waive any breach of, or any act, omission or default under, any of the Secured Debt Agreements or any of the instruments or agreements referred to therein, or otherwise amend, modify or supplement any of the Secured Debt Agreements or any of such other instruments or agreements;
(h)    act or fail to act in any manner which may deprive such Guarantor of its right to subrogation against any Canadian Borrower or any other Guaranteed Party to recover full indemnity for any payments made pursuant to this Canadian Guaranty; and/or
(i)    take any other action or omit to take any other action which would, under otherwise applicable principles of common law, give rise to a legal or equitable discharge of such Guarantor from its liabilities under this Canadian Guaranty (including, without limitation, any action or omission whatsoever that might otherwise vary the risk of such Guarantor or constitute a legal or equitable defense to or discharge of the liabilities of a guarantor or surety or that might otherwise limit recourse against such Guarantor).
No invalidity, illegality, irregularity or unenforceability of all or any part of the Guaranteed Obligations, the Secured Debt Agreements or any other agreement or instrument relating to the Guaranteed Obligations or of any security or guarantee therefor shall affect, impair or be a defense to this Canadian Guaranty, and this Canadian Guaranty shall be primary, absolute and unconditional notwithstanding the occurrence of any event or the existence of any other circumstances which might constitute a legal or equitable discharge of a surety or guarantor except the occurrence of the Termination Date.
6.    CONTINUING GUARANTY.  This Canadian Guaranty is a continuing one and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon.  No failure or delay on the part of any Secured Creditor in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege.  The rights and remedies herein expressly specified are cumulative and not exclusive of any rights or remedies which any Secured Creditor would otherwise have.  No notice to or 





Page #PageNum#


demand on any Guarantor in any case shall entitle such Guarantor to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Secured Creditor to any other or further action in any circumstances without notice or demand.  It is not necessary for any Secured Creditor to inquire into the capacity or powers of any Canadian Borrower or any other Guaranteed Party or the officers, directors, partners or agents acting or purporting to act on its or their behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.
7.    SUBORDINATION OF INDEBTEDNESS HELD BY GUARANTORS.  Any indebtedness of any Borrower, any other Guaranteed Party or any other U.S. Guaranty Guaranteed Party now or hereafter held by any Guarantor is hereby subordinated to the Guaranteed Obligations hereunder or under and as defined in the U.S. Guaranty, as applicable, of such Borrower or such other Guaranteed Party to the Secured Creditors; and the indebtedness of such Borrower, such other Guaranteed Party or such other U.S. Guaranty Guaranteed Party to any Guarantor, if the Administrative Agent or the Collateral Agent, after an Event of Default has occurred and is continuing, so requests, shall be collected, enforced and received by such Guarantor as trustee for the Secured Creditors and be paid over to the Secured Creditors on account of the Guaranteed Obligations hereunder or under and as defined in the U.S. Guaranty, as applicable, of such Borrower, such other Guaranteed Party or such other U.S. Guaranty Guaranteed Party to the Secured Creditors, but without affecting or impairing in any manner the liability of such Guarantor under the other provisions of this Canadian Guaranty.  Without limiting the generality of the foregoing, each Guarantor hereby agrees with the Secured Creditors that it will not exercise any right of subrogation which it may at any time otherwise have as a result of this Canadian Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) until the Termination Date; provided, that if any amount shall be paid to such Guarantor on account of such subrogation rights at any time prior to the Termination Date, such amount shall be held in trust for the benefit of the Secured Creditors and shall promptly be paid to the Secured Creditors to be credited and applied upon the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms of the Credit Documents or, if the Credit Documents do not provide for the application of such amount, to be held by the Secured Creditors as collateral security for any Guaranteed Obligations thereafter existing.
8.    GUARANTY ENFORCEABLE BY ADMINISTRATIVE AGENT OR COLLATERAL AGENT.  Notwithstanding anything to the contrary contained elsewhere in this Canadian Guaranty, the Secured Creditors agree (by their acceptance of the benefits of this Canadian Guaranty) that this Canadian Guaranty may be enforced only by the action of the Administrative Agent or the Collateral Agent, in each case acting upon the instructions of the Required Lenders and that no other Secured Creditor shall have any right individually to seek to enforce or to enforce this Canadian Guaranty or to realize upon the security to be granted by the Security Documents, it being understood and agreed that such rights and remedies may be exercised by the Administrative Agent or the Collateral Agent, as the case may be, for the benefit of the Secured Creditors upon the terms of this Canadian Guaranty and the Security Documents.  The Secured Creditors further agree that this Canadian Guaranty may not be enforced against any director, officer, employee, partner, member or stockholder of any Guarantor (except to the extent such partner, member or stockholder is also a Guarantor hereunder).  It is understood and agreed that the agreement in this Section 8 is among and solely for the benefit of the Secured Creditors and that, if the Required Lenders so agree (without requiring the consent of any Guarantor), this Canadian Guaranty may be directly enforced by any

Secured Creditor.

11.    BENEFIT AND BINDING EFFECT.  This Canadian Guaranty shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the Secured Creditors and their successors and assigns.
12.    AMENDMENTS; WAIVERS.  Neither this Canadian Guaranty nor any provision hereof may be changed, waived, discharged or terminated except with the written consent of each Guarantor directly affected thereby (it being understood that the addition or release of any Guarantor hereunder shall not constitute a change, waiver, discharge or termination affecting any Guarantor other than the Guarantor

16.    CONSENT TO JURISDICTION; SERVICE OF PROCESS; AND WAIVER OF TRIAL BY JURY.  (a)    THIS CANADIAN GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE SECURED CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE PROVINCE OF ONTARIO (WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES).

(b)    EACH GUARANTOR HEREBY IRREVOCABLY WAIVES (TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW) ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY OF THE AFORESAID ACTIONS OR PROCEEDINGS ARISING OUT OF OR IN CONNECTION WITH THIS CANADIAN GUARANTY OR ANY OTHER CREDIT DOCUMENT TO WHICH SUCH GUARANTOR IS A PARTY BROUGHT IN THE COURTS REFERRED TO IN CLAUSE (A) ABOVE THAT ARE LOCATED IN TORONTO, ONTARIO, AND HEREBY FURTHER IRREVOCABLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT SUCH ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

(c)    EACH GUARANTOR AND EACH SECURED CREDITOR (BY ITS ACCEPTANCE OF THE BENEFITS OF THIS CANADIAN GUARANTY) HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS CANADIAN GUARANTY, THE OTHER CREDIT DOCUMENTS TO WHICH SUCH GUARANTOR IS A PARTY OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.
17.    RELEASE OF LIABILITY OF GUARANTOR .  In the event that a Guarantor becomes an Immaterial Subsidiary or all of the Equity Interests of one or more Guarantors (other than a Canadian Borrower) is sold or otherwise disposed of or liquidated in compliance with the requirements of Section 10.02 of the Credit Agreement (or such sale, other disposition or liquidation has been approved in writing by the Required Lenders (or all the Lenders if required by Section 13.12 of the Credit Agreement)) and the proceeds of such sale, disposition or liquidation will be applied in accordance with the provisions of the Credit Agreement, to the extent applicable, such Immaterial Subsidiary, at the election of the Company in accordance with Section 9.12(e) of the Credit Agreement, or such Guarantor, as applicable, shall, or upon consummation of such sale or other disposition (except to the extent that such sale or disposition is to the Company or another Subsidiary thereof), as applicable, shall be released from this Canadian Guaranty automatically and without further action and this Canadian Guaranty shall, as to each such Guarantor or Guarantors, terminate, and have no further force or effect (it being understood and agreed that the sale of one or more Persons that own, directly or indirectly, all of the Equity Interests of any Guarantor shall be deemed to be a sale of such Guarantor for the purposes of this Section 17).  Subject to Section 15, on the Termination Date this Guaranty shall terminate (provided that all indemnities set forth herein shall survive such termination) and each Guarantor shall be released from its obligations under this Guaranty.
18.    CONTRIBUTION
At any time a payment in respect of the Guaranteed Obligations is made under this Canadian Guaranty, the right of contribution of each Guarantor against each other Guarantor shall be determined as provided in the immediately following sentence, with the right of contribution of each Guarantor to be revised and restated as of each date on which a payment (a “Relevant Payment”) is made on the Guaranteed Obligations under this Canadian Guaranty.  At any time that a Relevant Payment is made by a Guarantor that results in the aggregate payments made by such Guarantor in respect of the Guaranteed Obligations to and including the date of the Relevant Payment exceeding such Guarantor’s Contribution Percentage (as defined below) of the aggregate payments made by all Guarantors in respect of the Guaranteed Obligations to and including the date of the Relevant Payment (such excess, the “Aggregate Excess Amount”), each such Guarantor shall have a right of contribution against each other Guarantor who has made payments in respect of the Guaranteed Obligations to and including the date of the Relevant Payment in an aggregate amount less than such other Guarantor’s Contribution Percentage of the aggregate payments made to and including the date of the Relevant Payment by all Guarantors in respect of the Guaranteed Obligations (the aggregate amount of such deficit, the “Aggregate Deficit Amount”) in an amount equal to (x) a fraction the numerator of which is the Aggregate Excess Amount of such Guarantor and the denominator of which is the Aggregate Excess Amount of all Guarantors multiplied by (y) the Aggregate Deficit Amount of such other Guarantor.  A Guarantor’s right of contribution pursuant to the preceding sentences shall arise at the time of each computation, subject to adjustment to the time of each computation; provided that no Guarantor may take any action to enforce such right until the Termination Date, it being expressly recognized and agreed by all parties hereto that any Guarantor’s right of contribution arising pursuant to this Section 18 against any other 





Page #PageNum#


Guarantor shall be expressly junior and subordinate to such other Guarantor’s obligations and liabilities in respect of the Guaranteed Obligations and any other obligations owing under this Canadian Guaranty.  As used in this Section 18:  (i) each Guarantor’s “Contribution Percentage” shall mean the percentage obtained by dividing (x) the Adjusted Net Worth (as defined below) of such Guarantor by (y) the aggregate Adjusted Net Worth of all Guarantors; (ii) the “Adjusted Net Worth” of each Guarantor shall mean the greater of (x) the Net Worth (as defined below) of such Guarantor and (y) zero; and (iii) the “Net Worth” of each Guarantor shall mean the amount by which the fair saleable value of such Guarantor’s assets on the date of any Relevant Payment exceeds its existing debts and other liabilities (including contingent liabilities, but without giving effect to any Guaranteed Obligations arising under this Canadian Guaranty or any guaranteed obligations arising under any guaranty of any Permitted Additional Indebtedness) on such date.  Notwithstanding anything to the contrary contained above, any Guarantor that is released from this Canadian Guaranty pursuant to Section 17 hereof shall thereafter have no contribution obligations, or rights, pursuant to this Section 18, and at the time of any such release, if the released Guarantor had an Aggregate Excess Amount or an Aggregate Deficit Amount, same shall be deemed reduced to $0, and the contribution rights and obligations of the remaining Guarantors shall be recalculated on the respective date of release (as otherwise provided above) based on the payments made hereunder by the remaining Guarantors.  All parties hereto recognize and agree that, except for any right of contribution arising pursuant to this Section 18, each Guarantor who makes any payment in respect of the Guaranteed Obligations shall have no right of contribution or subrogation against any other Guarantor in respect of such payment until the Termination Date.  Each of the Guarantors recognizes and acknowledges that the rights to contribution arising hereunder shall constitute an asset in favor of the party entitled to such contribution.  In this connection, each Guarantor has the right to waive its contribution right against any Guarantor to the extent that after giving effect to such waiver such Guarantor would remain solvent, in the determination of the Required Lenders.


19.    COUNTERPARTS.  This Canadian Guaranty may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument.  A set of counterparts executed by all the parties hereto shall be lodged with the Company and the Administrative Agent.
20.    PAYMENTS.  All payments made by any Guarantor hereunder will be made without setoff, counterclaim or other defense and on the same basis as payments are made by the applicable Borrowers under Sections 5.03 and 5.04 of the Credit Agreement.
21.    JOINT AND SEVERAL OBLIGATIONS.  Notwithstanding any other provision contained in this Agreement or any other Credit Document, with respect to any Guarantor,  if a “secured creditor” (as that term is defined under the Bankruptcy and Insolvency Act (Canada)) is determined by a court of competent jurisdiction not to include a Person to whom obligations are owed on a joint or joint and several basis, then the obligations of each Guarantor under this Agreement or any other Credit Document, to the extent such obligations are secured, only shall be several obligations and not joint or joint and several obligations.
22.    JUDGMENT CURRENCY.  (a)    The Guarantors’ obligations hereunder to make payments in the Obligation Currency shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than the Obligation Currency, except to the extent that such tender or recovery results in the effective receipt by the Administrative Agent or the 





Page #PageNum#


other Secured Creditors of the full amount of the Obligation Currency expressed to be payable to the Administrative Agent or the other Secured Creditors under this Canadian Guaranty.  If for the purpose of obtaining or enforcing judgment against any Guarantor in any court or in any jurisdiction, it becomes necessary to convert into or from the Judgment Currency an amount due in the Obligation Currency, the conversion shall be made, at the rate of exchange (as quoted by the Administrative Agent or if the Administrative Agent does not quote a rate of exchange on such currency, by a known dealer in such currency designated by the Administrative Agent) determined, in each case, as of the Judgment Currency Conversion Date.  
(b)    If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount due, each Guarantor covenants and agrees to pay, or cause to be paid, such additional amounts, if any (but in any event not a lesser amount), as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial award at the rate or exchange prevailing on the Judgment Currency Conversion Date.
(c)    For purposes of determining any rate of exchange for this Section 22, such amounts shall include any premium and costs payable in connection with the purchase of the Obligation Currency.
23.    INTEREST ACT (CANADA).  For the purposes of the Interest Act (Canada):
(a)    whenever any interest or fee payable by a Guarantor under this Canadian Guaranty is calculated using a rate based on a year of 360 days or 365 days, as the case may be, the rate determined pursuant to such calculation, when expressed as an annual rate, is equivalent to (x) the applicable rate based on a year of 360 days or 365 days, as the case may be, (y) multiplied by the actual number of days in the calendar year in which such rate is to be ascertained and (z) divided by 360 or 365, as the case may be; and
(b)    all calculations of interest payable by a Guarantors under this Canadian Guaranty or any other Credit Document are to be made on the basis of the nominal interest rate described herein and therein and not on the basis of effective yearly rates or on any other basis which gives effect to the principle of deemed reinvestment of interest.  The parties hereto acknowledge that there is a material difference between the stated nominal interest rates and the effective yearly rates of interest and that they are capable of making the calculations required to determine such effective yearly rates of interest
24.    ADDITIONAL GUARANTORS.  It is understood and agreed that any Wholly-Owned Canadian Subsidiary of the Company that is required to execute a counterpart of this Canadian Guaranty after the date hereof pursuant to the Credit Agreement shall become a Guarantor hereunder by (x) executing and delivering a counterpart hereof, or a Joinder Agreement and delivering same to the Administrative Agent and (y) taking all actions as specified in this Canadian Guaranty as would have been taken by such Guarantor had it been an original party to this Canadian Guaranty, in each case with all documents required above to be delivered to the Administrative Agent and actions required to be taken above to be taken to the reasonable satisfaction of the Administrative Agent.
