          (i)  the due and punctual payment in full of the Outstanding Principal

               (including interest accruing after the filing of any petition in

               (whether at stated maturity or by required or optional prepayment
               or by acceleration or otherwise);

          (ii) the due and punctual payment and performance in full of all
               reimbursement and indemnity obligations of the Borrower to the
               Lender with respect to any bankers' acceptances issued or
               accepted by the Lender for the Borrower's account; and

          (iii) the due and punctual performance and observance by the Borrower
               of all of the terms, covenants, conditions, agreements,
               undertakings and obligations on the part of the Borrower to be
               performed or observed under the Credit Agreement in accordance
               with the terms thereof, as amended, waived, or varied in
               accordance with the terms thereof,

          (all such obligations described above in this Section 2.1(a) being
          herein collectively called the "GUARANTEED OBLIGATIONS").

     (b)  The guarantee provided in Section 2.1(a):

          (i)  is a continuing guarantee and shall guarantee the Guaranteed
               Obligations and any ultimate balance thereof, notwithstanding
               that the Borrower may from time to time satisfy the Guaranteed
               Obligations in whole or in part and thereafter incur further
               Guaranteed Obligations; and

          (ii) is an absolute, present and continuing guarantee of payment,
               performance or observance and not of collectibility and is in no
               way conditional or contingent upon any attempt to collect from
               the Borrower or any other guarantor of any of the Guaranteed
               Obligations or upon any other action, occurrence or circumstance
               whatsoever.

          In the event that the Borrower shall fail in any manner whatsoever to
          perform or observe any of the Guaranteed Obligations when the same
          shall be required to be paid, performed or observed, the Company will
          itself duly and punctually pay, perform and observe, or cause to be
          duly and punctually paid, performed and observed, the Guaranteed
          Obligations, without demand, presentment, protest or notice of any
          kind. For greater certainty, it shall not be a condition to the
          accrual



                                      -6-


          of the obligation of the Company hereunder to pay, perform or observe
          any of the Guaranteed Obligations (or to cause the same to be paid,
          performed or observed) that the Lender shall have first made any
          request of or demand upon or give any notice to the Company or to the
          Borrower or have initiated any action or proceeding against the
          Company or the Borrower and the Lender may proceed to enforce the
          obligations of the Company under this Section 2.1 without first
          pursuing or exhausting any right or remedy which it may have against
          the Borrower or any other Person. Each default in payment of the
          Outstanding Principal Obligations or interest thereon or in the
          payment, performance or observance of any other Guaranteed Obligation
          shall give rise to a separate cause of action hereunder and separate
          suits may be brought hereunder as each cause of action arises.

     (c)  In addition to the guarantee provided in Section 2.1(a), and as a
          separate and distinct obligation, the Company hereby agrees to
          indemnify and save harmless the Lender and its directors, officers and
          employees, forthwith on demand by the Lender, from and against any and
          all direct and indirect claims, demands, losses, damages, liabilities,
          charges, obligations, payments, costs and expenses of any nature or
          kind (including legal fees and disbursements), howsoever or whenever
          arising, which the Lender or its directors, officers and employees may
          incur or be subject to as a consequence, direct or indirect, of:

          (i)  the failure of the Borrower to pay and satisfy the Guaranteed
               Obligations in full;

          (ii) any breach by the Company or the Borrower of any warranty,
               covenant, term or condition in, or the occurrence of any default
               under, this Guarantee or the Credit Agreement, together with all
               expenses resulting from the compromise or defence of any claims
               or liabilities arising as a result of any such breach or default;

          (iii) any Guaranteed Obligations or the Credit Agreement or any
               agreement creating or relating to any or all Guaranteed
               Obligations in any way being or becoming for any reason
               whatsoever, in whole or in part, void, voidable, ultra vires,
               illegal, invalid, ineffective or otherwise unenforceable or
               released or discharged by operation of law or otherwise; or

          (iv) any legal action commenced to challenge the validity or
               enforceability of this Guarantee, the Credit Agreement or any
               Guaranteed Obligations,

          provided that any payment actually made by the Company to the Lender
          under Section 2.1(a) shall reduce the liability of the Company under
          this Section 2.1(c) by the same amount. The Company acknowledges that
          neither its obligation to indemnify, nor any actual indemnification by
          it, of the Lender or any other indemnified party hereunder in respect
          of such Person's Losses for the legal fees and expenses of such
          Person's counsel shall in any way affect the confidentiality



                                      -7-


          or privilege relating to any information communicated by such Person
          to its counsel. The provisions of this Section 2.1(c) shall survive
          the termination of this Guarantee, the termination or expiration of
          the Commitment and the payment or performance of all Guaranteed
          Obligations.

SECTION 2.2 COMPANY'S OBLIGATIONS ABSOLUTE.

          The obligations of the Company under this Guarantee shall be primary,
absolute, irrevocable and unconditional, irrespective of the genuineness,
validity, regularity or enforceability of the Guaranteed Obligations or of the
Credit Agreement, shall not be subject to any counterclaim, setoff, deduction or
defence based upon any claim the Company may have against the Borrower or the
Lender or otherwise, and this Guarantee and the obligations of the Company
hereunder shall remain in full force and effect without regard to, and shall not
be released, discharged, impaired or in any way affected by, any circumstance or
condition whatsoever, including:

          respect to the Credit Agreement or any Guaranteed Obligations or any

          any Guaranteed Obligations;

          Agreement or any Guaranteed Obligations, any other guarantees with
          respect to the Credit Agreement or any Guaranteed Obligations, or any
          other obligation of any Person with respect to the Credit Agreement or
          any Guaranteed Obligations;

     (f)  any bankruptcy, insolvency, reorganization, readjustment, composition,
          liquidation or similar proceeding with respect to the Borrower or its
          property or the occurrence of any Default or Event of Default;



                                      -8-


     (g)  any merger, amalgamation or consolidation of any of the Company or any
          of its Subsidiaries with any other Subsidiary or with any other entity

     (i)  any failure on the part of the Borrower for any reason to comply with
          or perform any of the terms of any other agreement with the Company;

     (j)  any application of any monies against such part of the Guaranteed
          Obligations and change of any such application in whole or in part at
          any time and from time to time as the Lender sees fit; or

     (k)  any other circumstance which might otherwise constitute a legal or
          equitable discharge or defence of a guarantor,

     all whether or not the Company shall have had notice or knowledge of any
     act or omission referred to in the foregoing clauses (a) through (k) of
     this Section 2.2. It is agreed that the Company's obligations hereunder are
     several and independent of any other guarantees, indemnities or security
     interests or other obligations at any time in effect with respect to the
     Guaranteed Obligations or any part thereof and that the Company's
     obligations hereunder may be enforced regardless of the existence,
     validity, enforcement or non-enforcement of any such other guarantees,
     indemnities or security interests or other obligations and no loss of or in
     respect of any other guarantees, indemnities or security interests or other
     obligations received by the Lender from any other Persons in respect of the
     Guaranteed Obligations, whether occasioned through the fault of any of the
     Lender or otherwise, shall in any way discharge or diminish the obligations
     of the Company. The Company covenants that its obligations hereunder will
     not be discharged except by indefeasible payment or performance in full of
     all of the Guaranteed Obligations.

SECTION 2.3 WAIVER.

          The Company unconditionally waives to the fullest extent permitted by
law:

     (a)  notice of acceptance hereof, of any action taken or omitted in
          reliance hereon and of any defaults by the Borrower in the payment of
          any amounts due under the Guaranteed Obligations or the Credit
          Agreement, and of any of the matters referred to in Section 2.2
          hereof;

     (b)  all notices which may be required by statute, rule of law or otherwise
          to preserve any of the rights of the Lender against the Company,
          including, without limitation, presentment to or demand for payment
          from the Borrower or the Company with respect to any Guaranteed
          Obligation, notice to the Borrower or the Company of default or
          protest for nonpayment or dishonor and the filing of claims with a
          court in the event of the bankruptcy of the Borrower;



                                      -9-


     (c)  any right to the enforcement, assertion or exercise by the Lender of
          any right, power or remedy conferred in this Guarantee, the Credit
          Agreement or the Guaranteed Obligations;

     (d)  any requirement of diligence on the part of the Lender; and

     (e)  any other act or omission or thing or delay to do any other act or
          thing which might in any manner or to any extent vary the risk of the
          Company or which might otherwise operate as a discharge of the
          Company.

SECTION 2.4 OBLIGATIONS UNIMPAIRED.

          The Company authorizes the Lender, without notice or demand to the
Company and without affecting its obligations hereunder, from time to time:

     (a)  to renew, compromise, extend, accelerate or otherwise change the time
          for payment of, or otherwise change the terms of, all or any part of
          the Guaranteed Obligations or the Credit Agreement or any other
          instrument referred to therein;

     (b)  to take and hold security for the payment of the Guaranteed
          Obligations, for the performance of this Guarantee or otherwise for
          the indebtedness guaranteed hereby and to exchange, enforce, waive and
          release any such security;

     (c)  to apply any such security and to direct the order or manner of sale
          thereof as the Lender in its sole discretion may determine;

     (d)  to obtain additional or substitute guarantors;

     (e)  to exercise or refrain from exercising any rights against the Company
          and others; and

     (f)  to apply as the Lender sees fit any sums, by whomsoever paid or
          however realized, to the payment of the Outstanding Principal
          Obligations and interest on the Outstanding Principal Obligations and
          any other Guaranteed Obligations.

          The Company waives any right to require the Lender to proceed against
any additional or substitute guarantors or to pursue or exhaust any security
provided by the Borrower, the Company or any other Person or to pursue any other
remedy available to the Lender.

SECTION 2.5 SUBROGATION.

     (a)  Subject to the final sentence of Section 2.5(c) hereof, the Company
          will not (i) exercise any rights which it may have acquired by way of
          subrogation under this Guarantee, by any payment made hereunder or any
          performance hereunder or otherwise, or (ii) accept any payment on
          account of such subrogation rights, or any rights of reimbursement,
          indemnity or any rights or recourse to any security or guarantee for
          any Guaranteed Obligations or this Guarantee unless and until all



                                      -10-


          of the obligations, undertakings or conditions to be performed or
          observed by the Borrower pursuant to the Guaranteed Obligations and
          the Credit Agreement at the time of the Company's exercise of any such
          right shall have been performed, observed or paid in full, provided
          that any right of subrogation acquired by the Company under this
          Guarantee, by any payment made hereunder or any performance hereunder
          or otherwise, shall be no greater than the rights held by the Lender
          and the Company hereby waives any benefit of any security or guarantee
          for any Guaranteed Obligations or this Guarantee and authorizes the
          Lender, subject to applicable Legal Requirements, to take any action
          or exercise any remedy, or refrain from taking any action or
          exercising any remedy, with respect thereto, which the Lender in its
          sole discretion shall determine, without notice to the Company.

     (b)  For a period of one hundred eighty (180) days after the payment in
          full of the Guaranteed Obligations, the Company will not, subject to
          the final sentence of Section 2.5(c) hereof, exercise (i) any rights
          of subrogation which it may at any time otherwise have as a result of
          this Guarantee (whether statutory or otherwise) to the claims of the
          Lender against the Borrower or any other guarantor of the Guaranteed
          Obligations (each referred to herein as the "OTHER PARTY") and all
          contractual, statutory or common law rights of reimbursement,
          contribution or indemnity from any Other Party which it may at any
          time otherwise have as a result of this Guarantee; (ii) any right to
          enforce any other remedy which the Lender now has or may hereafter
          have against any Other Party, any other guarantor of all or any part
          of the Guaranteed Obligations; and (iii) any claims (as such term is
          defined in the Bankruptcy Code) it may at any time otherwise have
          against any Other Party arising from any transaction whatsoever,
          including without limitation its right to assert or enforce any such
          claims.

     (c)  The Company hereby subordinates the payment of all Debt and other
          obligations of the Borrower or any Other Party owing to the Company,
          whether now existing or hereafter arising, including all rights and
          claims described in Sections 2.5(a) and (b) hereof, to the
          indefeasible payment or performance in full of all Guaranteed
          Obligations and, subject to the application of Section 2.5(b) hereof
          to the fullest extent permitted by applicable Legal Requirements, in
          the case of the liquidation, dissolution, winding-up, insolvency or
          bankruptcy of the Borrower (whether voluntary or involuntary) or in
          the event that the Borrower shall make an arrangement or composition
          with its creditors, the Lender shall have the right to rank in
          priority to the Company for the full claims of the Lender in respect
          of Guaranteed Obligations not then indefeasibly paid or performed in
          full until the claims of the Lender have been indefeasibly paid or
          performed in full all without prejudice to the claims of the Lender
          against the Company hereunder. If the Lender so requests, any such
          Debt or other obligations owing to the Company shall be enforced and
          performance received by the Company as trustee for the Lender and the
          proceeds thereof shall be paid over to the Lender to be credited and
          applied upon the Guaranteed Obligations, whether matured or unmatured,
          as may be directed by the Lender, but without reducing or affecting in
          any manner the liability of the Company under this Guarantee.



                                      -11-


     (d)  If any amount or other payment is made to or accepted by the Company
          in violation of the preceding Sections 2.5(a), (b) or (c), such amount
          shall be deemed to have been paid to the Company for the benefit of,
          and held in trust for the benefit of, the Lender and shall be paid
          over to the Lender, in the form received (together with any necessary
          endorsements), promptly upon request therefor, to be applied to the
          Guaranteed Obligations, whether matured or unmatured, in such order as
          may be directed by the Lender. The Company acknowledges that it will
          receive benefits from the financing arrangements contemplated by the
          Credit Agreement and that the waiver set forth in this paragraph is
          knowingly made in contemplation of such benefits.

SECTION 2.6 REINSTATEMENT.

          This Guarantee shall continue to be effective, or be reinstated, as
the case may be, if and to the extent at any time payment, in whole or in part,
of any of the sums due to the Lender in respect of any of the Guaranteed
Obligations is rescinded or must otherwise be restored or returned by the Lender
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
the Borrower, or upon or as a result of the appointment of a custodian,
receiver, trustee or other officer with similar powers with respect to the
Borrower or any substantial part of its property, or otherwise, all as though
such payments had not been made. If an event permitting the acceleration of the
maturity of any Guaranteed Obligations shall at any time have occurred and be
continuing and such acceleration shall at such time be prevented or the right of
the Lender to receive any payment in respect of any of the Guaranteed
Obligations shall at such time be delayed or otherwise affected by reason of a
case or proceeding under a bankruptcy or insolvency law, for purposes of this
Guarantee and the Company's obligations hereunder, the maturity of such
Guaranteed Obligations shall be deemed to have been accelerated with the same
effect as if the Lender had accelerated the same in accordance with the terms of
the Credit Agreement, and the Company shall forthwith pay such accelerated
Guaranteed Obligations and any other amounts guaranteed hereunder.

                                  ARTICLE III

                    with any other such liabilities or Liens then existing,
                    could reasonably be expected to have a Material Adverse
                    Effect;

          (vi) promptly, and in any event within 30 days of receipt thereof,
               copies of any notice to the Company or any Subsidiary from any
               Federal, state or provincial Governmental Authority relating to
               any order, ruling, statute or other law or regulation that could
               reasonably be expected to have a Material Adverse Effect;

          (vii) with reasonable promptness, such other data and information
               relating to the business, operations, affairs, financial
               condition, assets or properties of the Company or any of its
               Subsidiaries or relating to the ability of the Company to perform

               obligations under the Credit Agreement as from time to time may
               be reasonably requested by the Lender.

          The Company authorizes its independent chartered accountants to
          discuss the affairs, finances and accounts of the Company and its
          Subsidiaries with the representatives of the Lender as provided in

          rules or regulations to which each of them is subject, including,
          without limitation, Environmental Laws, and will obtain and maintain
          in effect all licenses, certificates, permits, franchises and other
          governmental authorizations necessary to the ownership of their
          respective properties or to the conduct of their respective
          businesses, in each case to the extent necessary to ensure that
          non-compliance with such laws, ordinances or governmental rules or
          regulations or failures to obtain or maintain in effect such licenses,
          certificates, permits, franchises and other governmental
          authorizations could not, individually or in the aggregate, reasonably
          be expected to have a Material Adverse Effect. Without limitation of
          the foregoing, the Company will, and will cause each of its
          Subsidiaries to, not be a Person described in Section 1 of the
          Anti-Terrorism Order, and not engage in any dealings or transactions,
          or otherwise be associated, with any such Person.

     (c)  Insurance. The Company will, and will cause each of its Subsidiaries
          to, maintain, with insurers reasonably determined by the Company in
          good faith to be financially sound and reputable, insurance with
          respect to their respective properties and businesses against such
          casualties and contingencies, of such types, on such terms and in such
          amounts (including deductibles, co-insurance and self-insurance, if
          adequate reserves are maintained with respect thereto) as is



                                      -15-


          customary in the case of entities of established reputations engaged
          in the same or a similar business and similarly situated.

     (d)  Maintenance of Properties. The Company will, and will cause each of
          its Subsidiaries to, maintain and keep, or cause to be maintained and
          kept, their respective properties in good repair, working order and
          condition (other than ordinary wear and tear), so that the business
          carried on in connection therewith may be properly conducted at all
          times, provided that this Section shall not prevent the Company or any
          Subsidiary from discontinuing the operation and the maintenance of any
          of its properties if such discontinuance is desirable in the conduct
          of its business and the Company has concluded that such discontinuance
          could not, individually or in the aggregate, reasonably be expected to
          have a Material Adverse Effect.

     (e)  Payment of Taxes and Claims. The Company will, and will cause each of
          its Subsidiaries to, file all tax returns required to be filed in any
          jurisdiction and to pay and discharge all taxes shown to be due and
          payable on such returns and all other taxes, assessments, governmental
          charges, or levies imposed on them or any of their properties, assets,
          income or franchises, to the extent such taxes and assessments have
          become due and payable and before they have become delinquent and all
          claims for which sums have become due and payable that have or might
          become a Lien on properties or assets of the Company or any
          Subsidiary, provided that neither the Company nor any Subsidiary need
          pay any such tax, assessment, charge, levy or claim if (a) the amount,
          applicability or validity thereof is contested by the Company or such
          Subsidiary on a timely basis in good faith and in appropriate
          proceedings, and the Company or a Subsidiary has established adequate
          reserves therefor in accordance with GAAP on the books of the Company
          or such Subsidiary or (b) the nonpayment of all such taxes and
          assessments in the aggregate could not reasonably be expected to have
          a Material Adverse Effect.

     (f)  Corporate Existence, etc. The Company will at all times preserve and
          keep in full force and effect its corporate existence. Subject to
          Sections 9.2(d), 9.2(e) and 9.2(g) of the Credit Agreement, the
          Company will at all times preserve and keep in full force and effect
          the legal existence of each of its Subsidiaries (unless merged,
          consolidated or amalgamated into or with the Company or another
          Subsidiary) and all rights and franchises of the Company and its
          Subsidiaries unless, in the good faith judgment of the Company, the
          termination of or failure to preserve and keep in full force and
          effect such legal existence, right or franchise could not,
          individually or in the aggregate, have a Material Adverse Effect.

     (g)  Payment of Obligations to Lender. The Company will duly and punctually
          pay to the Lender all amounts payable by the Company hereunder as and
          when the same become due.

     (h)  Enforceability. The Company will ensure that at all times and from
          time to time the execution and delivery of each of the Loan Documents
          by it and the


                                      -16-


          performance by it of its obligations thereunder will be, upon the
          execution and delivery thereof, duly authorized by all necessary
          corporate action; that all consents, approvals, orders,
          authorizations, licenses, exemptions or designations of or by any
          Governmental Authority or other Person required in connection with the
          execution, delivery and performance by it of any such documents have
          been obtained; and that all registrations, qualifications,
          designations, declarations or filings with any Governmental Authority
          necessary to enable or empower it to enter into and to perform its
          obligations under any such documents have been obtained and continue
          in full force and effect as required for such purpose; and that any
          and all Loan Documents to which it is a party have been duly executed
          and delivered by it and that each will constitute its legal, valid and
          binding obligation enforceable in accordance with its terms, subject
          only to bankruptcy, insolvency, arrangement and other laws affecting
          the enforcement of creditors' rights generally and the availability,
          in the discretion of a court of competent jurisdiction, of equitable
          remedies.

     (i)  Keeping of Books. The Company will keep, and cause each of its
          Subsidiaries to keep, financial books and records systems in
          accordance with Generally Accepted Accounting Principles and all
          applicable Legal Requirements, and in such books and records make full
          and correct entries of all financial transactions, Assets,
          liabilities, shareholders equity and business of the Company and each
          of its Subsidiaries in accordance with Generally Accepted Accounting
          Principles.

     (j)  Cure Defects. The Company will promptly cure or cause to be cured any
          defects in the execution, delivery, validity or enforceability of any
          of the Loan Documents or any of the other agreements, instruments or
          documents contemplated thereby or executed pursuant hereto or thereto
          and at its expense, execute and deliver or cause to be executed and
          delivered all such agreements, instruments and other documents and
          make all necessary filings and recordings as the Lender may consider
          reasonably necessary or desirable for the foregoing purposes.

     (k)  Obligations to Rank Pari Passu. The Obligations of the Company under
          this Guarantee are and at all times shall rank at least pari passu in
          right of payment with all other present and future unsecured Senior
          Debt (actual or contingent) of the Company.

     (l)  Further Assurances. The Company will, at its cost and expense, upon
          request of the Lender, duly execute and deliver, or cause to be duly
          executed and delivered, to the Lender all such further agreements,
          instruments, documents and other assurances and do and cause to be
          done all such further acts and things as may be necessary or desirable
          in the reasonable opinion of the Lender to carry out more effectually
          the provisions and purposes of this Guarantee or any of the other Loan
          Documents.



                                      -17-


                                   ARTICLE IV
                       NEGATIVE COVENANTS OF THE GUARANTOR

SECTION 4.1 NEGATIVE COVENANTS.

          From and after the Closing Date and so long as any Obligations remain
outstanding and unpaid or any Commitment shall continue to exist:

     (a)  Nature of Business. The Company will not, and will not permit any of
          its Subsidiaries to, engage in any business if, as a result, the
          general nature of the business in which the Company and its
          Subsidiaries, taken as a whole, would then be engaged would be
          substantially changed from the general nature of the business in which
          the Company and its Subsidiaries, taken as a whole, are engaged on the
          Closing Date.

     (b)  Transactions with Affiliates. The Company will not, and will not
          permit any Subsidiary to, enter into directly or indirectly any
          Material transaction or Material group of related transactions
          (including, without limitation, the purchase, lease, sale or exchange
          of properties of any kind or the rendering of any service) with any
          Affiliate (other than the Company or another Subsidiary), except in
          the ordinary course and pursuant to the reasonable requirements of the
          Company's or such Subsidiary's business and upon fair and reasonable
          terms no less favourable to the Company or such Subsidiary than would
          be obtainable in a comparable arm's-length transaction with a Person
          not an Affiliate.

     (c)  Most Favored Lender Status. The Company will not, and will not permit
          any Subsidiary to, enter into, assume or otherwise become bound or
          obligated under any agreement evidencing, securing, guaranteeing or
          otherwise relating to Designated Debt that contains, or amend any such
          agreement to contain, one or more Additional Covenants or Additional
          Defaults, unless the Company or such Subsidiary has offered to make an
          amendment to this Guarantee and the Credit Agreement, in form and
          substance satisfactory to the Lender, to add to or amend this
          Guarantee and the Credit Agreement to contain such Additional
          Covenants or Additional Defaults; provided, however, in the event that
          the Company or any Subsidiary enters into, assumes or otherwise
          becomes bound or obligated under, or so amends, any such agreement
          without making such offer, or if such offer was made and has not been
          rejected by the Lender, this Guarantee and the Credit Agreement shall,
          without any further action on the part of the Company, the Borrower or
          the Lender, be deemed to be amended automatically to include each
          Additional Covenant and each Additional Default contained in such
          agreement. The Company further covenants to, and to cause each of its
          Subsidiaries to, promptly execute and deliver at its expense
          (including the reasonable fees and expenses of counsel for the Lender)
          an amendment to this Guarantee and the Credit Agreement in form and
          substance satisfactory to the Lender evidencing the amendments of this
          Guarantee and the Credit Agreement to include such Additional
          Covenants and Additional Defaults, provided that the execution and
          delivery of such amendments shall not be a precondition to the
          effectiveness of



                                      -18-


          such amendment as provided for in this Section 4.1(c), but shall
          merely be for the convenience of the parties hereto.

     (d)  Defaults under Credit Agreement. The Company will not, and will not
          permit any Subsidiary to, take or fail to take any action if the
          taking or failing to take such action would cause a Default or an
          Event of Default to occur or continue to exist under the Credit
          Agreement. Without limiting the generality of the foregoing, the
          Company will, and will cause each of its Subsidiaries to, take, or
          refrain from taking, any action, as from time to time requested by the
          Borrower, in order to enable the Borrower to cause the Company and its
          Subsidiaries to comply with the provisions of Articles 9 and 10 of the
          Credit Agreement.

                                   ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

SECTION 5.1 REPRESENTATIONS AND WARRANTIES BY THE COMPANY.

          The Company represents and warrants to the Lender as follows, and
acknowledges that the Lender is relying thereon without independent inquiry in
entering into the Credit Agreement and making any Advance under the Credit
Agreement:

     (a)  Organization; Power and Authority. The Company is a corporation duly
          incorporated and validly existing under the laws of Canada, and is
          duly qualified as a foreign corporation and is in good standing in
          each jurisdiction in which such qualification is required by law,
          other than those jurisdictions as to which the failure to be so
          qualified or in good standing could not, individually or in the
          aggregate, reasonably be expected to have a Material Adverse Effect.
          The Company has the corporate power and authority to own or hold under
          lease the properties it purports to own or hold under lease, to
          transact the business it transacts and proposes to transact, to
          execute and deliver this Guarantee and to perform the provisions
          hereof.

     (b)  Authorization, Etc. This Guarantee has been duly authorized by all
          necessary corporate action on the part of the Company, and this
          Guarantee constitutes, a legal, valid and binding obligation of the
          Company enforceable against the Company in accordance with its terms,
          except as such enforceability may be limited by (a) applicable
          bankruptcy, insolvency, reorganization, moratorium or other similar
          laws affecting the enforcement of creditors' rights generally and (b)
          general principles of equity (regardless of whether such
          enforceability is considered in a proceeding in equity or at law).

     (c)  Disclosure. Except as disclosed in Schedule 5.1(c), this Guarantee,
          the documents, certificates or other writings delivered to the
          Purchasers by or on behalf of the Company or the Borrower in
          connection with the transactions contemplated by the Credit Agreement
          and the financial statements listed in Schedule 5.1(e), taken as a
          whole, do not contain any untrue statement of a material fact or omit
          to state any material fact necessary to make the statements



                                      -19-


          therein not misleading in light of the circumstances under which they
          were made. Except as expressly described in Schedule 5.1(c), or in one
          of the documents, certificates or other writings identified therein,
          or in the financial statements listed in Schedule 5.1(e), since
          December 31, 2004, there has been no change in the financial
          condition, operations, business, properties or prospects of the
          Company or any Subsidiary except changes that, individually or in the
          aggregate, could not reasonably be expected to have a Material Adverse
          Effect. There is no fact known to the Company that could reasonably be
          expected to have a Material Adverse Effect that has not been set forth
          herein or in the other documents, certificates and other writings
          delivered to the Lender by or on behalf of the Company specifically
          for use in connection with the transactions contemplated hereby.

     (d)  Organization and Ownership of Shares of Subsidiaries; Affiliates.

          (i)  Schedule 5.1(d) contains (except as noted therein) complete and
               correct lists (1) of the Company's Material Subsidiaries,
               showing, as to each Material Subsidiary, the correct name
               thereof, the jurisdiction of its organization, the percentage of
               shares of each class of its share capital or similar equity
               interests outstanding owned by the Company and each other
               Subsidiary and, as of the date of the Closing, whether such
               Subsidiary is a Material Subsidiary, (2) of the Company's
               Affiliates, other than Material Subsidiaries, and (3) of the
               Company's directors and senior officers.

          (ii) All of the outstanding share capital or similar equity interests
               of each Subsidiary shown in Schedule 5.1(d) as being owned by the
               Company and its Subsidiaries have been validly issued, are fully
               paid and nonassessable and are owned by the Company or another
               Subsidiary free and clear of any Lien (except as otherwise
               disclosed in Schedule 5.1(d)).

          (iii) Each Subsidiary identified in Schedule 5.1(d) is a corporation
               or other legal entity duly organized, validly existing and in
               good standing under the laws of its jurisdiction of organization,
               and is duly qualified as a foreign corporation or other legal
               entity and is in good standing in each jurisdiction in which such
               qualification is required by law, other than those jurisdictions
               as to which the failure to be so qualified or in good standing
               could not, individually or in the aggregate, reasonably be
               expected to have a Material Adverse Effect. Each such Subsidiary
               has the corporate or other power and authority to own or hold
               under lease the properties it purports to own or hold under lease
               and to transact the business it transacts and proposes to
               transact.

          (iv) No Subsidiary is a party to, or otherwise subject to any legal
               restriction or any agreement (other than the Credit Agreement,
               the agreements listed on Schedule 5.1(d) and customary
               limitations imposed by corporate law and insurance regulatory
               statutes or other statutes governing the organization of legal
               entities) restricting the ability of such Subsidiary to pay
               dividends



                                      -20-


               out of profits or make any other similar distributions of profits
               to the Company or any of its Subsidiaries that owns any
               outstanding share capital or similar equity interests of such
               Subsidiary.

     (e)  Financial Statements. The Company has delivered to each Purchaser
          copies of the financial statements of the Company and its Subsidiaries
          listed on Schedule 5.1(e). All of said financial statements (including
          in each case the related schedules and notes) fairly present, in all
          material respects, the consolidated financial position of the Company
          and its Subsidiaries as of the respective dates specified in such
          Schedule and the consolidated results of their operations and cash
          flows for the respective periods so specified and have been prepared
          in accordance with GAAP consistently applied throughout the periods
          involved except as set forth in the notes thereto (subject, in the
          case of any interim financial statements, to normal year-end
          adjustments).

     (f)  Compliance with Laws, Other Instruments, Etc. The execution, delivery
          and performance by the Company of this Guarantee and the consummation
          of the Reorganization will not (a) contravene, result in any breach
          of, or constitute a default under, or result in the creation of any
          Lien in respect of any property of the Company or any Subsidiary
          under, any indenture, mortgage, deed of trust, loan, purchase or
          credit agreement, lease, corporate charter or by-laws, or any other
          Material agreement or instrument to which the Company or any
          Subsidiary is bound or by which the Company or any Subsidiary or any
          of their respective properties may be bound or affected, (b) conflict
          with or result in a breach of any of the terms, conditions or
          provisions of any order, judgment, decree or ruling of any court,
          arbitrator or Governmental Authority applicable to the Company or any
          Subsidiary or (c) violate any provision of any statute or other rule
          or regulation of any Governmental Authority applicable to the Company
          or any Subsidiary.

     (g)  Governmental Authorizations, Etc. No consent, approval or
          authorization of, or registration, filing or declaration with, any
          Governmental Authority is required in connection with the execution,
          delivery or performance by the Company of this Guarantee or the
          consummation of the Reorganization, other than those consents,
          approvals or authorizations obtained and those registrations, filings
          or declarations made on or before the date of the Closing.

     (h)  Litigation; Observance of Agreements, Statutes and Orders.

          (i)  Except as disclosed in the financial statements described in
               Schedule 5.1(e), there are no actions, suits or other proceedings
               pending or, to the knowledge of the Company, threatened against
               or affecting the Company or any Subsidiary or any property of the
               Company or any Subsidiary in any court or before any arbitrator
               of any kind or before or by any Governmental Authority that,
               individually or in the aggregate, could reasonably be expected to
               have a Material Adverse Effect.



                                      -21-


          (ii) Neither the Company nor any Subsidiary is in default under any
               term of any agreement or instrument to which it is a party or by
               which it is bound, or any order, judgment, decree or ruling of
               any court, arbitrator or Governmental Authority or is in
               violation of any applicable law, ordinance, rule or regulation
               (including, without limitation, Environmental Laws) of any
               Governmental Authority, which default or violation, individually
               or in the aggregate, could reasonably be expected to have a
               Material Adverse Effect.

     (i)  Taxes. The Company and its Subsidiaries have filed all income tax
          returns that are required to have been filed in any jurisdiction, and
          have paid all taxes shown to be due and payable on such returns and
          all other taxes and assessments levied upon them or their properties,
          assets, income or franchises, to the extent such taxes and assessments
          have become due and payable and before they have become delinquent,
          except for any taxes and assessments (a) the amount of which is not,
          individually or in the aggregate, Material or (b) the amount,
          applicability or validity of which is currently being contested in
          good faith by appropriate proceedings and with respect to which the
          Company or a Subsidiary, as the case may be, has established adequate
          reserves in accordance with GAAP. The Company knows of no basis for
          any other tax or assessment that could reasonably be expected to have
          a Material Adverse Effect. The charges, accruals and reserves on the
          books of the Company and its Subsidiaries in respect of United States
          and Canadian federal, state, provincial or other taxes for all fiscal
          periods are adequate. The Canadian federal and provincial income tax
          liabilities of the Company and its Subsidiaries have been determined
          by the Canadian Customs and Revenue Agency and corresponding
          provincial taxing authorities by the issuance of notices of assessment
          for all fiscal years up to and including the fiscal year ended
          December 31, 2004, and the Company and its Subsidiaries have paid any
          taxes indicated to be owing on such notices of assessment. The United
          States federal income tax liabilities of the Company and its
          Subsidiaries have been determined by the Internal Revenue Service and
          paid for all fiscal years up to and including the fiscal year ended
          December 31, 2004.

     (j)  Title to Property; Leases. The Company and its Subsidiaries have good
          and sufficient title to their respective properties that, individually
          or in the aggregate, are Material, including all such properties
          reflected in the most recent audited balance sheet referred to in

          Liens prohibited by this Guarantee. All leases that, individually or
          in the aggregate, are Material are valid and subsisting and are in

     (k)  Licenses, Permits, Etc. Except as disclosed in the financial
          statements described in Schedule 5.1(e),



                                      -22-


          (i)  the Company and its Subsidiaries own, possess or are licensed to
               use all licenses, permits, franchises, authorizations, patents,
               copyrights, service marks, trademarks, trade names and domain
               names, or rights thereto, that, individually or in the aggregate,
               are Material, without known conflict with the rights of others;

          (ii) to the best knowledge of the Company, no product of the Company
               infringes in any material respect any license, permit, franchise,
               authorization, patent, copyright, service mark, trademark, trade
               name, domain name or other right owned by any other Person; and

          (iii) to the best knowledge of the Company, there is no Material
               violation by any Person of any right of the Company or any of its
               Subsidiaries with respect to any patent, copyright, service mark,
               trademark, trade name, domain name or other right owned or used
               by the Company or any of its Subsidiaries.

     (l)  Compliance with ERISA.

          (i)  All Canadian pension plans of the Company and its Subsidiaries
               have been established, operated, administered and maintained in
               compliance with all applicable laws, regulations and orders
               applicable thereto except where the failure to comply could not
               reasonably be expected to have a Material Adverse Effect. All
               premiums, contributions and any other amounts required by
               applicable Canadian pension plan documents or applicable laws
               have been paid or accrued as required, except where the failure
               to pay such premiums, contributions and amounts could not
               reasonably be expected to have a Material Adverse Effect.

          (ii) The Company and each ERISA Affiliate have operated and
               administered each employee benefit plan (as defined in Section
               3(3) of ERISA) in compliance with all applicable laws except for
               such instances of noncompliance as have not resulted in and could
               not reasonably be expected to result in a Material Adverse
               Effect. Neither the Company nor any ERISA Affiliate has incurred
               any liability pursuant to Title I or IV of ERISA or the penalty
               or excise tax provisions of the Code relating to employee benefit
               plans (as defined in Section 3 of ERISA), and no event,
               transaction or condition has occurred or exists that could
               reasonably be expected to result in the incurrence of any such
               liability by the Company or any ERISA Affiliate, or in the
               imposition of any Lien on any of the rights, properties or assets
               of the Company or any ERISA Affiliate, in either case pursuant to
               Title I or IV of ERISA or to such penalty or excise tax
               provisions or to Section 401(a)(29) or 412 of the Code, other
               than such liabilities or Liens as could not, individually or in
               the aggregate, reasonably be expected to result in a Material
               Adverse Effect.



                                      -23-


          (iii) The present value of the aggregate benefit liabilities under
               each of the Plans (other than Multiemployer Plans), determined as
               of the end of such Plan's most recently ended plan year on the
               basis of the actuarial assumptions specified for funding purposes
               in such Plan's most recent actuarial valuation report, did not
               exceed the aggregate current value of the assets of such Plan
               allocable to such benefit liabilities by more than $1,000,000 in
               the aggregate for all Plans. The term "BENEFIT LIABILITIES" has
               the meaning specified in Section 4001 of ERISA and the terms
               "CURRENT VALUE" and "PRESENT VALUE" have the meanings specified
               in Section 3 of ERISA.

          (iv) The Company and its ERISA Affiliates have not incurred withdrawal
               liabilities (and are not subject to contingent withdrawal
               liabilities) under Section 4201 or 4204 of ERISA in respect of
               Multiemployer Plans that could, individually or in the aggregate,
               reasonably be expected to result in a Material Adverse Effect.

          (v)  The expected post-retirement benefit obligation (determined as of
               the last day of the Company's most recently ended fiscal year in
               accordance with Financial Accounting Standards Board Statement
               No. 106, without regard to liabilities attributable to
               continuation coverage mandated by Section 4980B of the Code) of
               the Company and its Subsidiaries is not Material.

          (vi) The execution and delivery of this Guarantee will not involve any
               transaction that is subject to the prohibitions of Section 406(a)
               of ERISA or in connection with which a tax could be imposed
               pursuant to Section 4975(c)(1)(A)-(D) of the Code for which an
               exemption is not available.

     (m)  Existing Debt; Future Liens.

          (i)  Except as described therein, the financial statements described
               in Schedule 5.1(e) set forth a complete and correct list of all
               outstanding Debt of the Company and its Subsidiaries as of
               December 31, 2005 since which date there has been no Material
               change in the amounts, interest rates, sinking funds, installment
               payments or maturities of the Debt of the Company or its
               Subsidiaries. Neither the Company nor any Subsidiary is in
               default and no waiver of default is currently in effect, in the
               payment of any principal or interest on any Debt of the Company
               or such Subsidiary and no event or condition exists with respect
               to any Debt of the Company or any Subsidiary that would permit
               (or that with notice or the lapse of time, or both, would permit)
               one or more Persons to cause such Debt to become due and payable
               before its stated maturity or before its regularly scheduled
               dates of payment.

          (ii) Except as disclosed in the financial statements described in
               Schedule 5.1(e), neither the Company nor any Subsidiary has
               agreed or consented to cause or permit in the future (upon the
               happening of a contingency or



                                      -24-


               otherwise) any of its property, whether now owned or hereafter
               acquired, to be subject to a Lien not permitted by Section 9.2(c)
               of the Credit Agreement.

     (n)  Foreign Assets Control Regulations, Etc. The Company's execution,
          delivery and performance of this Guarantee and the consummation of the
          Reorganization will not violate the Anti-Terrorism Order, the Patriot
          Act or the Trading with the Enemy Act, as amended, or any of the
          foreign assets control regulations of the United States Treasury
          Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling
          legislation or executive order relating thereto.

     (o)  Status under Certain Statutes. Neither the Company nor any Subsidiary
          is required to be registered under the Investment Company Act of 1940,
          as amended, the Public Utility Holding Company Act of 1935, as
          amended, the ICC Termination Act of 1995, as amended, or the Federal
          Power Act, as amended.

     (p)  Environmental Matters. Neither the Company nor any Subsidiary has
          knowledge of any claim or has received any notice of any claim, and no
          proceeding has been instituted raising any claim against the Company
          or any of its Subsidiaries or any of their respective real properties
          now or formerly owned, leased or operated by any of them or other
          assets, alleging any damage to the environment or violation of any
          Environmental Laws, except, in each case, such as could not reasonably
          be expected to result in a Material Adverse Effect. Except as
          otherwise disclosed to each Purchaser in writing:

          (i)  neither the Company nor any Subsidiary has knowledge of any facts
               which would give rise to any claim, public or private, of
               violation of Environmental Laws or damage to the environment
               emanating from, occurring on or in any way related to real
               properties now or formerly owned, leased or operated by any of
               them or to other assets or their use, except, in each case, such
               as could not reasonably be expected to result in a Material
               Adverse Effect;

          (ii) neither the Company nor any of its Subsidiaries has stored any
               Hazardous Materials on real properties now or formerly owned,
               leased or operated by any of them or has disposed of any
               Hazardous Materials in a manner contrary to any Environmental
               Laws in each case in any manner that could reasonably be expected
               to result in a Material Adverse Effect; and

          (iii) all buildings on all real properties now owned, leased or
               operated by the Company or any of its Subsidiaries are in
               compliance with applicable Environmental Laws, except where
               failure to comply could not reasonably be expected to result in a
               Material Adverse Effect.

     (q)  Guarantee Ranks Pari Passu. The obligations of the Company under this
          Guarantee rank at least pari passu in right of payment with all other
          Senior Debt



                                      -25-


          (actual or contingent) of the Company, including, without limitation,
          all Senior Debt of the Company described in Schedule 5.1(m).

     (r)  Permitted Senior Indebtedness. The obligations of the Company under
          this Guarantee constitute Permitted Senior Indebtedness, as defined in
          the Subordinated Debentures.

SECTION 5.2 SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

          The representations and warranties herein set forth or contained in
any certificates or documents delivered to the Lender pursuant hereto shall
survive the execution and delivery of the Guarantee and the execution and
delivery of the Credit Agreement and the making or conversion of any Advance
under the Credit Agreement and any investigation at any time made by or on
behalf of the Lender. All statements contained in any certificate or other
instrument delivered by or on behalf of the Company pursuant to this Guarantee
shall be deemed representations and warranties of the Company under this
Guarantee. The representations and warranties shall be deemed to be repeated by
the Company upon each Drawdown Date (except as otherwise stated by the Borrower
in the related Advance Request), and all references to the Closing Date
contained in such representations and warranties shall be deemed to refer to
each Drawdown Date.

                                   ARTICLE VI
                                     GENERAL

SECTION 6.1 EVIDENCE OF OBLIGATIONS.

          The Obligations of the Company hereunder shall, absent manifest error,
be prima facie evidenced by the records of the Lender.

SECTION 6.2 REMEDIES CUMULATIVE.

          The rights and remedies of the Lender hereunder are cumulative and are
in addition to and not in substitution for any other rights or remedies provided
by law. Nothing contained herein or in any Loan Documents now or hereafter held
by the Lender with respect to the Obligations of the Company to the Lender, or
any part thereof, nor any act or omission of the Lender with respect to such
Loan Documents, shall in any way prejudice or affect the rights, remedies and
powers of the Lender with respect to any other such Loan Documents.

SECTION 6.3 RIGHT OF SET-OFF.

          Upon the occurrence and during the continuance of an Event of Default,
the Lender is hereby authorized by the Company at any time and from time to time
and may to the fullest extent permitted by law, set off, appropriate and apply
any and all deposits (general or special, time or demand, matured or unmatured,
provisional or final) at any time held and other indebtedness at any time owing
to or for the credit or the account of the Company (other than as trustee)
against any and all of the Obligations of the Company now or hereafter existing
hereunder. The Lender shall promptly notify the Company after any such set-off
and application made by the Lender, provided that the failure to give such
notice shall not affect the validity of



                                      -26-


such set-off and application. The rights of the Lender under this Section 6.3
are in addition to all other rights and remedies (including, without limitation,
other rights of set-off) which the Lender may have.

SECTION 6.4 JUDGMENT CURRENCY.

          The obligation of the Company to make payments on any Obligations to
the Lender hereunder in any currency (the "FIRST CURRENCY") shall not be
discharged or satisfied by any tender or recovery pursuant to any judgment
expressed in or converted into any other currency (the "SECOND CURRENCY") except
to the extent to which such tender or recovery shall result in the effective
receipt by the Lender of the full amount of the first currency payable, and
accordingly the primary obligation of the Company shall be enforceable as an
alternative or additional cause of action for the purpose of recovery in the
second currency of the amount (if any) by which such effective receipt shall
fall short of the full amount of the first currency payable and shall not be
affected by a judgment being obtained for any other sum due hereunder.

SECTION 6.5 INVALIDITY OF ANY PROVISIONS.

          Any provision of this Guarantee which is prohibited by the laws of any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition without invalidating the remaining terms and provisions hereof
or thereof and no such invalidity shall affect the obligation of the Company to
pay the Obligations in full. The rate of interest chargeable or collectable on
overdue instalments of interest shall not exceed the maximum rate permitted by
applicable law.

SECTION 6.6 AMENDMENTS, WAIVERS, ETC.

          No amendment, modification or waiver of any provision of, and no
waiver of the strict observance, performance or compliance by the Company with
any term, covenant, condition or agreement contained in this Guarantee and no
indulgence granted by the Lender or consent to any departure by the Company
therefrom, shall in any event be effective unless it shall be in writing and
signed by the Lender (and the Company in the case of amendments or modifications
or waivers by the Company), and then such amendment, modification, waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it is given. Notwithstanding the foregoing, no failure to
exercise and no delay in exercising any right, power or privilege under this
Guarantee shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege under this Guarantee preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The remedies herein provided are cumulative and not exclusive of any
other rights or remedies available at or provided by law.

will save the Lender harmless from, all claims in respect of any fees, costs or
expenses, if any, of brokers and finders. The provisions of this Section 6.8
shall survive the termination of this Guarantee, the termination or expiration
of the Commitment and the payment or performance of all Guaranteed Obligations.

SECTION 6.9 TAXES.

     (a)  Any and all payments to the Lender by the Company hereunder (or under
          any of the other Loan Documents) shall be made free and clear of and
          without deduction or withholding for any and all present and future
          Taxes, imposed by any Governmental Authority including, without
          limitation, any Taxes which arise from the execution, delivery or
          registration of, or otherwise with respect to, this Guarantee or any
          of the other Loan Documents, unless such Taxes are required by law or
          the administration thereof to be deducted or withheld. If the Company
          shall be required by law or the administration thereof to deduct or
          withhold any such Taxes from or in respect of any amount payable
          hereunder, (i) the amount payable shall be increased as may be
          necessary so that after making all required deductions or withholdings
          (including deductions or withholdings applicable to additional amounts
          paid under this paragraph), the Lender receives an amount equal to the
          amount it would have received if no such deduction or withholding had
          been made; (ii) the Company shall make such deductions or
          withholdings; and (iii) the Company shall pay forthwith the full
          amount deducted or withheld to the relevant taxation or other
          authority in accordance with applicable law.

     (b)  The Company agrees to indemnify the Lender for the full amount of
          Taxes not deducted or withheld and paid by the Borrower in accordance
          with Section 6.9(a) to the relevant taxation or other authority and
          any Taxes imposed by any jurisdiction on amounts payable by the
          Borrower under this Section 6.9, paid by the Lender and any liability
          (including penalties, interest and expenses) arising therefrom or with
          respect thereto, whether or not any such Taxes were correctly or



                                      -29-


          legally asserted. Payment under this indemnification shall be made
          within fifteen days from the date the Lender makes written demand
          therefor. A certificate as to the amount of such Taxes, providing
          reasonable details of the calculation thereof, and evidence of payment
          thereof submitted to the Company by the Lender shall be conclusive
          evidence of the amount due from the Company to the Lender absent
          manifest error.

     (c)  The Company shall furnish to the Lender the original or a certified
          copy of a receipt evidencing any payment of Taxes made by the Company,
          as soon as such receipt becomes available (or if such original or
          certified tax receipt is not available, such other evidence of payment
          as may be acceptable to the Lender), together with such other
          documentary evidence with respect to such payments as may be
          reasonably requested from time to time by the Lender.

     (d)  If the provisions of Section 6.9(a) or 6.9(b) require the Company to
          deduct or withhold and pay Taxes to any relevant taxation or other
          authority or to pay any additional amounts thereunder, the Lender
          shall use its reasonable efforts (consistent with its internal policy
          and legal and regulatory restrictions) to avoid the necessity of
          invoking such provisions of this Section 6.9, or to reduce the amounts
          payable thereunder, including changing the jurisdiction of its
          applicable lending office; provided that the taking of any such action
          would not, in the reasonable judgment of the Lender, be
          disadvantageous to the Lender.

     (e)  For the avoidance of doubt, nothing herein shall (i) restrict the
          right of the Lender to arrange its tax affairs as it shall deem
          appropriate or (ii) require the Lender to disclose any information
          regarding its tax affairs or computations to the Company or any other
          Person other than as shall be necessary to permit the Company to
