The Corporation does not do business with respect to the Collateral under any name other than PCI Chemicals Canada Inc./Produits Chimiques PCI Canada Inc. 4.12 OPERATION BY THIRD PARTIES. To the extent any of the Collateral is operated by a party or parties other than the Corporation, the Corporation's covenants as expressed hereunder are modified to require that the Corporation use its best efforts (including without limitation the reasonable exercise of all rights and remedies as are available to the Corporation) to obtain compliance with such covenants by the operator or operators of the Collateral. 4.13 COMPLIANCE WITH LAWS. The Plants comply in all material respects with all local land use requirements of Governmental Entities except for possible nonconforming uses or violations which do not and will not materially interfere with the present use, operation or maintenance thereof as now used, operated or maintained. 4.14 PAYMENT OF TAXES, INSURANCE PREMIUMS, ASSESSMENTS; COMPLIANCE WITH LAWS AND INSURANCE REQUIREMENTS. (a) Unless contested in accordance with the provisions of section 4.14(e) hereof, the Corporation shall pay and discharge or cause to be paid and discharged, from time to time when the same shall become due, all real estate and other taxes, special assessments, levies, permits, inspection and license fees, all premiums for insurance, all water and sewer rents and charges, and all other public charges imposed upon or assessed against the Collateral or any part thereof or upon the revenues, rents, issues, income and profits of the Collateral, including, without limitation, those arising in respect of the occupancy, use or possession thereof. (b) During the continuance of an Event of Default, the Corporation shall deposit with the Collateral Agent, on the first day of each month, an amount reasonably estimated by the Corporation to be equal to one-twelfth (1/12th) of the annual taxes, assessments and other items required to be discharged by the Corporation under section 4.14(a) and amounts reasonably estimated by the Corporation to be necessary to maintain the insurance coverages contemplated in section 4.16 below, which estimates shall not be less than one-twelfth (1/12th) of the annual taxes, assessments, insurance premiums and other items required to be discharged by the Corporation during the year immediately preceding the year during 15 - 15 - which such Event of Default occurred. Such amounts shall be held by the Collateral Agent without interest to the Corporation and applied to the payment of each obligation in respect of which such amounts were deposited, in such order or priority as the Collateral Agent shall determine, on or before the date on which such obligation would become delinquent. If at any time the amounts so deposited by the Corporation shall, in the Collateral Agent's judgment, be insufficient (when added to the instalments anticipated to be paid thereafter) to discharge any of such obligations when due, the Corporation shall, immediately upon demand, deposit with the Collateral Agent such additional amounts as may be requested by the Collateral Agent. Nothing contained in this section 4.14 shall affect any right or remedy of the Collateral Agent under any provision of this Debenture or of any statute or rule of Law to pay any such amount from its own funds (provided, however, that the Collateral Agent shall not in any event be obligated to pay any of such amounts from its own funds) and to add the amount so paid, together with interest at the Rate of Interest, to the obligations, or relieve the Corporation of its obligations to make or provide for the payment of the annual taxes, assessments and other charges required to be discharged by the Corporation under section 4.14(a). All sums held pursuant to this section 4.14 shall form part of the Collateral. During the continuance of any Event of Default, the Collateral Agent may apply all or any part of the sums held pursuant to this section 4.14 to payment and performance of the Obligations in accordance with the provisions of the Intercreditor Agreement. The Corporation shall redeposit with the Collateral Agent an amount equal to all amounts so applied as a condition to the cure, if any, of such Event of Default, in addition to fulfilment of any other required conditions. (c) Unless contested in accordance with the provisions of section 4.14(e), the Corporation shall timely pay (or obtain a bond in the amount of) all lawful claims and demands of mechanics, materialmen, labourers, warehousemen, employees, suppliers, government agencies administering worker's compensation insurance, old age pensions and social security benefits and all other claims, judgments, demands or amounts of any nature which, if unpaid or not bonded, could result in or permit the creation of a Lien (other than a Permitted Lien) on the Collateral or any part thereof or the Rents arising therefrom, or which might result in forfeiture of all or any part of the Collateral. (d) The Corporation shall maintain, or cause to be maintained, in full force and effect, all permits, certificates, authorizations, consents, approvals, registrations, filings, licenses, franchises or other instruments now or hereafter required by any Governmental Entity to operate or use and occupy the Plants and the Equipment for its intended uses (collectively, the "PERMITS"; each, a "PERMIT"), unless the failure to maintain such Permits would not individually or in the aggregate have a Material Adverse Effect. Unless contested in accordance with the provisions of section 4.14(e), the Corporation shall comply promptly with, or cause prompt compliance with, all requirements set forth in the Permits and all Governmental Requirements applicable to all or any part of the Collateral or the condition, use or occupancy of all or any part thereof or any recorded deed of restriction, declaration, covenant running with the land or otherwise, now or hereafter in force unless the compliance therewith would not individually or in the aggregate have a Material Adverse Effect. The Corporation shall not initiate or consent to any change in the zoning, subdivision or any other use classification of the Real Property, if such action could have a material adverse effect on the Security Interest or materially impair the present use and operation of the Collateral or materially impair the Collateral Agent's rights or benefits hereunder, without the prior written consent of the Collateral Agent. 16 - 16 - (e) The Corporation may at its own expense contest the amount or applicability of any of the obligations described in sections 4.14(a), 4.14(c) and 4.14(d) by appropriate legal proceedings, prosecution of which operates to prevent the collection or enforcement thereof or the sale or forfeiture of the Collateral or any part thereof to satisfy such obligations; provided, however, that: (i) any such contest shall be conducted in good faith by appropriate legal proceedings promptly instituted and diligently conducted; and (ii) in connection with such contest, the Corporation shall have made provision for the payment or performance of such contested obligation on the Corporation's books if and to the extent required by generally accepted accounting principles then utilized by the Corporation in the preparation of its financial statements, or shall have deposited with the Collateral Agent a sum sufficient to pay and discharge such obligation and the Collateral Agent's estimate of all interest and penalties related thereto. Notwithstanding the foregoing provisions of this section 4.14(e): (iii) no contest of any such obligations may be pursued by the Corporation if such contest would expose the Collateral Agent, or any of the Administrative Agent, the Trustee, the Noteholders or the Lenders to any possible criminal liability or, unless the Corporation shall have furnished an Additional Undertaking therefor satisfactory to the Collateral Agent in respect of any civil liability for failure to comply with such obligations; and (iv) if at any time payment or performance of any obligation contested by the Corporation pursuant to this section 4.14(e) shall become necessary to prevent the delivery of a tax or similar deed conveying the Collateral or any portion thereof because of nonpayment or nonperformance, the Corporation shall pay or perform the same in sufficient time to prevent the delivery of such tax or similar deed. (f) The Corporation shall not in its use and occupancy of the Plants or the Equipment (including, without limitation, in the making of any Alteration) take any action that would cause the termination, revocation or denial of any insurance coverage required to be maintained under this Debenture or, that pursuant to written notice from any applicable insurer, would be the basis for a defense to any claim under any insurance policy maintained in respect of any of the Plants or the Equipment and the Corporation shall otherwise comply in all material respects with the requirements of any insurer that issues a policy of insurance in respect of any of the Plants or the Equipment. (g) The Corporation shall, promptly upon receipt of any written notice regarding any failure by the Corporation to pay or discharge any of the obligations described in section 4.14(a) or 4.14(f), furnish a copy of such notice to the Collateral Agent. The Corporation shall, promptly upon receipt of any written notice regarding any failure by the Corporation to pay or discharge any of the obligations described in section 4.14(c) or 4.14(d), furnish a copy of such notice to the Collateral Agent, if such failure would have a Material Adverse Effect. 17 - 17 - 4.15 CERTAIN TAX LAW CHANGES. In the event of the passage after the date of this Debenture of any Law deducting from the value of real property, for the purpose of taxation, amounts in respect of any Lien thereon or changing in any way the Laws for the taxation of debentures or debts secured by debentures for federal, provincial, municipal or local purposes or the manner of the collection of any such taxes, and imposing a new tax, either directly or indirectly, on this Debenture or the interest of any of the Collateral Agent, the Administrative Agent, the Trustee, the Lenders and the Noteholders in any Collateral (other than income, franchise or similar taxes imposed on such Person), or in the event that any regulation or regulatory amendment becoming effective after the date hereof imposes any federal or provincial or municipal or local tax on interest income received with respect to any Obligation, the Corporation shall promptly pay the Collateral Agent such amount or amounts as may be necessary from time to time to pay such tax. 4.16 REQUIRED INSURANCE POLICIES. (a) The Corporation shall maintain, or cause to be maintained, as of and from the Closing Date, in full force and effect the following insurance coverages in respect of the Plants and the Equipment: (i) Physical hazard insurance on an "all risk" basis covering hazards commonly covered by fire and extended coverage, lightning, civil commotion, hail, riot, strike, water damage, sprinkler leakage, collapse and malicious mischief, in an amount equal to the full replacement cost of the Buildings and all Equipment, with such deductibles as would be maintained by a prudent operator of property similar in use and configuration to the Plant and located in the locality where such Plant is located.

All insurance policies in respect of the coverages required by sections 4.16(a)(i), 4.16(a)(iv), 4.16(a)(vi) and, if applicable, 4.16(a)(vii) shall be in amounts at least sufficient to prevent coinsurance liability and all losses thereunder shall be payable to the Collateral Agent, as loss payee, subject to the terms of the Intercreditor Agreement, pursuant to a standard Canadian Insurance Bureau standard mortgagee clause for use in the Province of Nova Scotia, or any equivalent thereof, and each such policy shall, to the extent obtainable at commercially reasonable costs, (i) include effective waivers (whether under the terms of such policy or otherwise) by the insurer of all claims for insurance premiums against all loss payees and named insureds other than the Corporation and all rights of subrogation against any named insured, and (ii) provide that any losses thereunder shall be payable notwithstanding (I) any act, failure to act, negligence of, or violation or breach of warranties, declarations or conditions contained in such policy by the Corporation or the Collateral Agent or any other named insured or loss payee, (II) the occupation or use of the Plant or the Equipment for purposes more hazardous than permitted by the terms of the policy, (III) any foreclosure or other proceeding or notice of sale relating to the Plant or the Equipment, or (IV) any change in the title to or ownership or possession of the Plant or the Equipment; provided, 19 - 19 - however, that (with respect to items contemplated in clauses (III) and (IV) above) any notice requirements of the applicable policies are satisfied. All insurance policies in respect of the coverages required by sections 4.16(a)(ii), 4.16(a)(v) and, if applicable, 4.16(a)(vii) shall name the Collateral Agent as an additional insured. (c) Each policy of insurance required under this section 4.16 shall provide that: (i) notices of any failure by the Corporation to pay any insurance premium in respect thereof, be furnished to the Collateral Agent contemporaneously with any such notice given to the Corporation and (ii) it may not be cancelled or otherwise terminated without at least twenty (20) days' prior written notice to the Collateral Agent and shall permit the Collateral Agent to pay any premium therefor within twenty (20) days after receipt of any notice stating that such premium has not been paid when due. The policy or policies of such insurance or certificates of insurance evidencing the required coverages and all renewals or extensions thereof shall be delivered to the Collateral Agent upon receipt by the Corporation. Settlement of any claim under any of the insurance policies referred to in this section 4.16 (other than the insurance contemplated in section 4.16(a)(iii) which in the Corporation's reasonable judgment involves loss of $1,000,000 in lawful currency of the United States or more, shall require the prior approval of the Collateral Agent (acting pursuant to the provisions of the Intercreditor Agreement) and the Corporation shall use its best efforts to cause each such insurance policy to contain a provision to such effect.

The Corporation immediately shall notify the Collateral Agent whenever any such separate insurance policy is obtained and promptly shall deliver to the Collateral Agent the policy or certificate evidencing such insurance. 4.17 INSPECTION. The Corporation shall permit the Collateral Agent, by its agents, accountants and attorneys, to visit and inspect the Collateral upon reasonable prior notice at such times as may be reasonably requested by the Collateral Agent. 20 - 20 - 4.18 THE CORPORATION TO MAINTAIN IMPROVEMENTS. The Corporation shall not commit any waste on the Plants or with respect to any Equipment or make any change in the use of the Plant or any Equipment. The Corporation represents and warrants that: (a) to the Corporation's knowledge, the Plants are served by all electric, gas, sewer, water facilities and any other utilities required or necessary for the current use thereof and any easements or servitudes necessary to the furnishing of such utility service by the Corporation have been obtained and duly recorded, and (b) the Corporation has access to the Plants from public roads sufficient to allow the Corporation and its tenants and invitees to conduct its and their businesses at the Plants as they are currently conducted. The Corporation shall not materially alter the occupancy or use of the Plant without the prior written consent of the Collateral Agent. Except as otherwise permitted by the Intercreditor Agreement, no Buildings comprising a portion of any of the Plants may be demolished nor shall any Equipment be removed without the prior written consent of the Collateral Agent. 4.19 LEASES. (a) All of the Leases are valid and effective in accordance with their respective terms, except that the enforcement thereof may be subject to: (i) bankruptcy, insolvency, reorganization, moratorium or other similar Laws affecting or relating to enforcement of creditors' rights generally, and (ii) general equitable principles. To the Corporation's knowledge, the Corporation is not in material breach of or in default (and to the Corporation's knowledge, no event has occurred which with due notice or lapse of time or both, may constitute such a material breach or default) under any Lease, and no party to any Lease has given the Corporation written notice of or made a claim with respect to any breach or default, the consequences of which, individually or in the aggregate, would have a Material Adverse Effect on the Corporation. (b) The Corporation shall manage and operate the Collateral or cause the Collateral to be managed and operated in a reasonably prudent manner and, except as otherwise permitted under section 4.20, will not enter into any Lease (or any amendment or modification thereof) or other agreement subsequent to the date hereof with any Person which, in the reasonable judgment of the Corporation, individually or in the aggregate, would have a Material Adverse Effect on the value of the property subject thereto. (c) The Corporation shall not: (i) receive or collect, or permit the receipt or collection of, any rental or other payments under any Lease more than one (1) month in advance of the respective period in respect of which they are to accrue, except that (i) in connection with the execution and delivery of any Lease or of any amendment to any Lease, rental payments thereunder may be 21 - 21 - collected and received in advance in an amount not in excess of one (1) month's rent and (ii) the Corporation may receive and collect escalation and other charges in accordance with the terms of each Lease; (ii) assign, transfer, mortgage or grant a security interest in (other than to the Collateral Agent hereunder or as otherwise permitted under section 4.20 of this Debenture) any rental or other payment under any Lease whether then due or to accrue in the future, the interest of the Corporation as lessor under any Lease or the Rents, issues, revenues, profits or other income of the Collateral; (iii) enter into any Lease after the date hereof that does not contain terms to the effect as follows: (I) such Lease and the rights of the tenant thereunder shall be subject and subordinate to the rights of the Collateral Agent under this Debenture; (II) such Lease has been mortgaged or charged by the Corporation, as landlord thereunder, to the Collateral Agent under this Debenture; (III) in the case of any foreclosure, the rights and remedies of the tenant in respect of any obligations of any successor landlord thereunder shall be limited to the equity interest of such successor landlord in the Plant and any successor landlord shall not (a) be liable for any act, omission or default of any prior landlord under the Lease or (b) be required to make or complete any tenant improvements or capital improvements or repair, restore, rebuild or replace the demised premises or any part thereof in the event of damage, casualty or condemnation or (c) be required to pay any amounts to tenant arising under the Lease prior to such successor landlord taking possession; (IV) the tenant's obligation to pay rent and any additional rent shall not be subject to any abatement, deduction, counterclaim or setoff as against the Collateral Agent or any purchaser upon any foreclosure hereunder in respect of any portion of a Plant, and the Collateral Agent or such purchaser will not be bound by any advance payments of rent in excess of one month or any security deposits unless such security was actually received; and (V) the tenant agrees to attorn, at the option of the Collateral Agent or any purchaser of a Plant, to the successor owner upon any foreclosure hereunder in respect of a Plant or the giving or granting of a deed in lieu thereof; and (iv) terminate or permit the termination of any Lease of space, accept surrender of all or any portion of the space demised under any Lease prior to the end of the term thereof or accept assignment of any Lease to the Corporation which, in the reasonable judgment of the Corporation, individually or in the aggregate, would have a Material Adverse Effect or materially impair the Security Interest unless: 22 - 22 - (I) the tenant under such Lease has not paid the equivalent of two months' rent and the Corporation has made reasonable efforts to collect such rent; or (II) the Corporation shall deliver to the Collateral Agent an officer's certificate to the effect that the Corporation has entered into a new Lease (or Leases) for the space covered by the terminated or assigned Lease with a term (or terms) which expire(s) no earlier than the date on which the terminated or assigned Lease was to expire (excluding renewal options), and with a tenant (or tenants) having a creditworthiness (as reasonably determined by the Corporation) sufficient to pay the rent and other charges due under the new Lease (or Leases), and the tenant(s) shall have commenced paying rent, including, without limitation, all operating expenses and other amounts payable under the new Lease (or Leases), without any abatement or concession, in an amount at least equal to the amount which would have then been payable under the terminated or assigned Lease. (d) The Corporation timely shall perform and observe all the terms, covenants and conditions required to be performed and observed by the Corporation under each Lease and will not engage in any conduct in respect of any Lease which would have individually or in the aggregate a Material Adverse Effect or materially impair the Security Interest. The Corporation promptly shall notify the Collateral Agent of the receipt of any notice from any lessee under any Lease claiming that the Corporation is in material default in the performance or observance of any of the terms, covenants or conditions thereof to be performed or observed by the Corporation and will cause a copy of each such notice to be delivered promptly to the Collateral Agent. 4.20 TRANSFER RESTRICTIONS. Except as otherwise permitted by the Intercreditor Agreement, the Corporation shall not, without the prior written consent of the Collateral Agent, further mortgage, encumber, hypothecate, sell, convey or assign all or any part of the Collateral or suffer any of the foregoing to occur by operation of Law or otherwise (each a "TRANSFER"); provided, however, the Corporation may so encumber the Collateral to the extent such encumbrances are of the kind listed in clause (d) of the definition of "Permitted Liens". Any proceeds of such permitted Transfer shall be deemed Collateral Proceeds (as defined in the Indenture) and are hereby assigned and shall be paid to the Collateral Agent to be held in the Collateral Account (as defined in the Intercreditor Agreement) and disbursed pursuant to the Intercreditor Agreement. 4.21 DESTRUCTION; EXPROPRIATION. (a) If there shall occur any damage to, or loss or destruction of, the Buildings and Equipment, or any part of any thereof (each, a "DESTRUCTION"), the Corporation shall promptly send to the Collateral Agent a notice setting forth the nature and extent of such Destruction. The proceeds of any insurance payable in respect of any such Destruction are hereby assigned and shall be paid to the Collateral Agent to be held in the Collateral Account; provided, however, that so long as no Event of Default shall have occurred and be continuing, if such proceeds are in an amount less than $1,000,000 in lawful currency of the United States, such proceeds shall be paid directly to the Corporation. All insurance proceeds paid to the Collateral Agent pursuant to this section, less the amount of any expenses incurred in litigating, arbitrating, compromising or settling any claim arising out of such Destruction (the 23 - 23 - "INSURANCE PROCEEDS"), shall constitute Moneys and be applied in accordance with the provisions of sections 4.21(c), 4.21(d) and 4.21(e). (b) If there shall occur any taking of the Collateral or any part thereof, in or by expropriation proceedings pursuant to any Law, general or special, or by reason of the temporary requisition of the use or occupancy of the Collateral or any part thereof, by any Governmental Entity, civil or military (each, a "TAKING"), the Corporation immediately shall notify the Collateral Agent upon receiving notice of such Taking or commencement of proceedings therefor. The Collateral Agent may (but shall not be obligated to) participate in any proceedings or negotiations which might result in any Taking. The Collateral Agent may be represented by counsel satisfactory to it at the expense of the Corporation. The Corporation shall deliver or cause to be delivered to the Collateral Agent all instruments requested by it to permit such participation. The Corporation shall in good faith and with due diligence file and prosecute what would otherwise be the Corporation's claim for any such award or payment and cause the same to be collected and paid over to the Collateral Agent, and hereby irrevocably authorizes and empowers the Collateral Agent, in the name of the Corporation as its true and lawful attorney-in-fact or otherwise, during the continuance of an Event of Default to collect and to receipt for any such award or payment, and, in the event the Corporation fails so to act, to file and prosecute such claim. The Corporation shall pay all costs, fees and expenses incurred by the Collateral Agent in connection with any Taking and seeking and obtaining any award or payment on account thereof. Any proceeds, award or payment in respect of any Taking are hereby assigned and shall be paid to the Collateral Agent to be held in the Collateral Account; provided, however, that so long as no Event of Default shall have occurred and be continuing, if such proceeds are in an amount less than $1,000,000 in lawful currency of the United States, such proceeds shall be paid directly to the Corporation. The Corporation shall take all steps necessary to notify the condemning authority of such assignment. Such proceeds, award or payment paid to the Collateral Agent, less the amount of any expenses incurred in litigating, arbitrating, compromising or settling any claim arising out of such Taking ("NET AWARD"), shall constitute Moneys and be applied in accordance with the provisions of sections 4.21(c), 4.21(d) and 4.21(e). (c) So long as no Event of Default shall have occurred and be continuing, the Corporation shall have the right, at the Corporation's option, to perform a restoration (a "RESTORATION") of the affected portions of the Plant and the Equipment. In the event the Corporation elects to perform a Restoration, the Corporation shall give written notice ("RESTORATION ELECTION NOTICE") of such election to the Collateral Agent within twenty (20) business days after the date that the Collateral Agent receives the applicable Insurance Proceeds or Net Award, as the case may be. The Corporation shall, within twenty (20) business days following the date of delivery of a Restoration Election Notice, commence and diligently continue to perform the Restoration of that portion or portions of the Plant and Equipment subject to such Destruction or affected by such Taking so that, upon the completion of the Restoration, the Collateral shall be in the same condition and shall be of at least equal utility for its intended purposes as the Collateral was immediately prior to such Destruction or Taking. The Corporation shall so complete such Restoration with its own funds to the extent that the amount of any Net Award or Insurance Proceeds is insufficient for such purpose. In the event the Collateral Agent does not receive a Restoration Election Notice within such twenty (20) business day period, the Collateral Agent shall deal with such Insurance Proceeds or Net Award in accordance with the provisions of the Intercreditor Agreement. 24 - 24 - (d) In the event a Restoration is to be performed under this section 4.21(d), the Collateral Agent shall not release any part of the Net Award or the Insurance Proceeds except in accordance with the provisions of section 4.21(e) and the Corporation shall, prior to commencing any work to effect a Restoration of the Plant and the Equipment, promptly (but in no event later than one-hundred twenty (120) days following any Destruction or Taking) furnish to the Collateral Agent: (i) complete plans and specifications (the "PLANS AND SPECIFICATIONS") for the Restoration; (ii) an officers' certificate stating that all permits and approvals required by Law to commence work in connection with the Restoration have been obtained; (iii) a certificate (an "ARCHITECT'S CERTIFICATE") of an independent, reputable architect or engineer acceptable to the Collateral Agent and licensed in the Province of Nova Scotia (i) stating that the Plans and Specifications have been reviewed and approved by the signatory thereto, (ii) containing such signatory's estimate (an "ESTIMATE") of the costs of completing the Restoration, and (iii) upon completion of such Restoration in accordance with the Plans and Specifications, the utility of the Plant and the Equipment will be equal to or greater than the utility thereof immediately prior to the Destruction or Taking relating to such Restoration; and (iv) if the Estimate exceeds the Insurance Proceeds or the Net Award, as the case may be, by $5,000,000 in lawful currency of the United States or more, an Additional Undertaking in an amount equal to not less than the Estimate less the amount of the Insurance Proceeds or the Net Award, as the case may be, then held by the Collateral Agent for application toward the cost of such Restoration. Upon receipt by the Collateral Agent of each of the items required pursuant to sections 4.21(d)(i) through 4.21(d)(iv) above, the Collateral Agent shall acknowledge receipt of the Plans and Specifications. Promptly upon such acknowledgment of receipt by the Collateral Agent, the Corporation shall commence and diligently continue to perform the Restoration substantially in accordance with such Plans and Specifications and in material compliance with all Governmental Requirements, free and clear of all Liens except Permitted Liens. The Corporation shall so complete such Restoration with its own funds to the extent that the amount of any Net Award or Insurance Proceeds is insufficient for such purpose. (e) In the event the Corporation performs a Restoration of any of the Plants and Equipment as provided in section 4.21(d), the Collateral Agent shall apply any Insurance Proceeds or Net Award held by the Collateral Agent on account of the Destruction or Taking to the payment of the cost of performing such Restoration pursuant to the relevant provisions of the Intercreditor Agreement. In the event there shall be any surplus after application of the Net Award or the Insurance Proceeds to Restoration of the Plants and the Equipment, such surplus shall become Net Proceeds, as defined in the Indenture for application in accordance thereunder; provided, however, that if an Event of Default shall have occurred and be continuing, such surplus shall be applied by the Collateral Agent to the payment of the Obligations, in accordance with Article 6 of the Intercreditor Agreement. Notwithstanding anything to the contrary herein, if a Destruction or Taking of all or substantially all of the Collateral 25 - 25 - occurs on a date which is less than 12 months prior to Maturity, as such term is defined in the Indenture, all Insurance Proceeds and Net Awards shall be applied to the permanent repayment or prepayment of any Secured Obligations then outstanding in accordance with the Intercreditor Agreement. 4.22 ALTERATIONS. The Corporation shall not make any material structural addition, modification or change (each, an "ALTERATION") to any Plant or the Equipment which would materially diminish the utility of the Collateral or impair the Security Interest. Whether or not the Collateral Agent has consented to the making of any Alteration, the Corporation shall (i) complete each Alteration promptly, in a good and workmanlike manner and in material compliance with all applicable local Laws, and (ii) pay when due all claims for labour performed and materials furnished in connection with such Alteration, unless contested in accordance with the provisions of section 4.14(e). 4.23 HAZARDOUS MATERIAL (a) Except with respect to those matters which would not reasonably be expected to have a Material Adverse Effect, to the best knowledge of the Corporation, the Corporation holds all Permits required to permit the Corporation to conduct its business in the manner now conducted and none of the Corporation's operations are being conducted in a manner that violates in any material respect the terms and conditions under which any such Permit was granted, including without limitation, under any Environmental Laws, except those permits that are expected to be transferred in the ordinary course after the date hereof; to the best of the knowledge of the Corporation all such Permits are valid and in full force and effect; and to the knowledge of the Corporation, no suspension, cancellation, revocation or termination of any such Permit is threatened. (b) Except as set forth in the Term Loan Agreement, there are no material claims, actions, suits, proceedings or investigations pending or to the knowledge of the Corporation, threatened, before any Governmental Entity or before any arbitrator brought by or against the Corporation or with respect to any of the Collateral the basis of which is any Environmental Law. (c) The Corporation shall (or shall cause other parties obligated to do so under or in accordance with contracts with or indemnity to the Corporation): (i) take all commercially reasonable actions to comply with any and all applicable present and future Environmental Laws relating to the Plants; (ii) pay in a timely fashion the cost of any removal, response measure or corrective action relating to any Hazardous Materials required by any Environmental Law or any order, regulation, consent decree or similar agreement or instrument and keep the Collateral free of any Lien imposed pursuant to any Environmental Law; (iii) take all commercially reasonable actions to not Release any Hazardous Materials on, under or from the Collateral in violation of any Environmental Law; 26 - 26 - (iv) apply any insurance proceeds or other sums received by it in respect of the removal of any Hazardous Material or any other corrective action relating to any Hazardous Material to such removal or corrective action; and (v) not take, or fail to take any action required under any Environmental Laws or in connection with any Hazardous Materials that could reasonably be expected to result in the incurrence of any obligation or liability of any of the Collateral Agent, Administrative Agent, Trustee, Lenders or Noteholders. During the continuance of an Event of Default, in the event the Corporation fails to comply with the covenants in the preceding sentence, the Collateral Agent may (upon receipt of an indemnity satisfactory to the Collateral Agent), in addition to any other remedies set forth herein, but shall not be obligated to, as mandatary for and at the Corporation's sole cost and expense cause to be taken, any remediation, removal, response or corrective action relating to Hazardous Materials that is required by Environmental Law and is not being done or contested by the Corporation. Any costs or expenses incurred by the Collateral Agent for such purpose shall be immediately due and payable by the Corporation and shall bear interest at the Rate of Interest. The Corporation shall provide to the Collateral Agent and its agents and employees access to the Collateral to take any action required by Environmental Laws, or in connection with any Hazardous Materials, that could be expected to result in the incurrence of any obligation or liability of any of the Collateral Agent, Administrative Agent, Trustee, Lenders or Noteholders, if the Corporation fails to do so and such action or removal is required under any Environmental Laws as provided above. Upon written request by the Collateral Agent, which shall include a reasonably specific statement of the basis thereof (which shall be specific to the condition of the Collateral and the alleged violation of Environmental Law) and which shall be made not more frequently than once in any twelve-month period or at any time that the Collateral Agent is exercising its remedies under this Debenture, the Collateral Agent shall have the right (upon receipt of an indemnity satisfactory to the Collateral Agent), but shall not be obligated, at the sole cost and expense of the Corporation, to conduct an environmental audit or review of the Collateral relating to the specific items as required in writing or relating to the remedy that the Collateral Agent is exercising under this Debenture by persons or firms appointed by the Collateral Agent, and the Corporation shall cooperate in all reasonable respects in the conduct of such environmental audit or review, including, without limitation, by providing reasonable access to the Collateral and to all records relating thereto. The Corporation shall indemnify and hold each of the Collateral Agent, Administrative Agent, Trustee, Lenders and Noteholders harmless from and against all loss, cost, damage or expense (including, without limitation, attorneys' fees) that any of the Collateral Agent, Administrative Agent, Trustee, Lenders and Noteholders may sustain by reason of the assertion against such party of any claim relating to such Hazardous Materials or actions taken with respect thereto as authorized hereunder. Nothing contained herein shall result in any of the Collateral Agent, Administrative Agent, Trustee, Lenders and Noteholders being deemed an "owner" or "operator" under applicable Environmental Law. 27 - 27 - (d) The Corporation may at its own expense contest the amount or applicability of any of the obligations described in the first sentence of section 4.23(c) by appropriate legal proceedings, prosecution of which operates to prevent the enforcement thereof; provided, however, that: (i) any such contest shall be conducted in good faith by appropriate legal proceedings promptly instituted and diligently conducted and (ii) in connection with such contest, the Corporation shall have made provision for the payment or performance of such contested obligation on the Corporation's books if and to the extent required by generally accepted accounting principles then utilized by the Corporation in the preparation of its financial statements, or shall have deposited with the Collateral Agent a sum sufficient to pay and discharge such obligation and the Collateral Agent's estimate of all interest and penalties related thereto. Notwithstanding the foregoing provisions of this section 4.23(d), no contest of any such obligations may be pursued by the Corporation if such contest would expose the Collateral Agent, or any of the Administrative Agent, Trustee, Lenders or Noteholders to any possible criminal liability or, unless the Corporation shall have furnished an Additional Undertaking therefor satisfactory to the Collateral Agent or for any civil liability for failure to comply with such obligations. 4.24 ASBESTOS. The Corporation shall not install nor permit to be installed in the Collateral friable asbestos or any asbestos-containing material (collectively, "ACM") except in compliance with all applicable Environmental Laws respecting such material. With respect to any ACM currently present in the Collateral, except with respect to matters which would not have a Material Adverse Effect, the Corporation shall comply with all Laws applicable to ACM located on any of the Plants, all at the Corporation's sole cost and expense. If the Corporation shall fail so to comply with such Laws, the Collateral Agent may (upon receipt of an indemnity satisfactory to the Collateral Agent) during the continuance of an Event of Default, but shall not be obligated to, in addition to any other remedies set forth herein, take those steps reasonably necessary to comply with applicable Laws. Any costs or expenses incurred by the Collateral Agent for such purpose shall be immediately due and payable by the Corporation and bear interest at the Rate of Interest. The Corporation shall provide to the Collateral Agent and its agents and employees reasonable access to the Collateral upon reasonable prior notice to remove such ACM if the Corporation fails to do so and removal is required under any Environmental Law as provided for above; provided, however, that nothing contained herein shall obligate the Collateral Agent to exercise any rights under such access. The Corporation shall indemnify and hold each of the Collateral Agent, Administrative Agent, Trustee, Lenders and Noteholders harmless from and against all loss, cost, damage and expense that any of the Collateral Agent, Administrative Agent, Trustee, Lenders and Noteholders may sustain as a result of the presence of any ACM and any removal thereof in compliance with any applicable Environmental Law. 4.25 BOOKS AND RECORDS; REPORTS. The Corporation shall keep proper books of record and account, which shall accurately represent the financial condition of the Corporation and the business affairs of the Corporation relating to the Collateral. The Collateral Agent and its authorized representatives shall have the right, from time to time, upon reasonable prior notice to examine the books and records of the Corporation relating to the operation of the Collateral at the office of the Corporation. 28 - 28 - 4.26 NO CLAIMS AGAINST THE COLLATERAL AGENT. Nothing contained in this Debenture shall constitute any consent or request by the Collateral Agent, express or implied, for the performance of any labour or services or the furnishing of any materials or other property in respect of the Plant or any part thereof, nor as giving the Corporation any right, power or authority to contract for or permit the performance of any labour or services or the furnishing of any materials or other property in such fashion as would permit the making of any claim against the Collateral Agent in respect thereof or any claim that any Lien based on the performance of such labour or services or the furnishing of any such materials or other property is ranked in priority to the Security Interest. 4.27 UTILITY SERVICES. The Corporation shall pay, or cause to be paid, when due all charges for all public or private utility services, all public or private rail and highway services, all public or private communication services, all sprinkler systems, and all protective services, any other services of whatever kind or nature at any time rendered to or in connection with the Plants or any part thereof, shall comply in all material respects with all contracts relating to any such services, and shall do all other things reasonably required for the maintenance and continuance of all such services to the extent required to fulfil the obligations set forth in section 4.18. ARTICLE 5 DEFAULT AND ENFORCEMENT 5.1 DEFAULT. The Security Interest shall become enforceable against the Corporation if and only if and when the Corporation shall fail to pay, perform or satisfy any of the Obligations when due and payable or required to be performed or satisfied, as the case may be, but not otherwise (each such failure is an "Event of Default"). Upon the occurrence of an Event of Default, the Obligations shall immediately become due and payable by the Corporation to the Collateral Agent without necessity of any further act or formality and, thereafter, the Corporation shall not be entitled to sell, assign, transfer, exchange, lease or otherwise dispose of or deal with all or any part of the Collateral. 5.2 REMEDIES. Whenever the Security Interest has become enforceable, the Collateral Agent may in its discretion: (a) take possession of all or any part of the Collateral with power to exclude the Corporation and its officers, employees and agents therefrom; (b) take all such steps as the Collateral Agent may consider necessary or desirable for the purposes of preserving, maintaining and completing all or any part of the Collateral and making such replacements thereof and improvements and additions thereto as the Collateral Agent may consider expedient; (c) carry on all or any part of the business of the Corporation relating to the Collateral and use all or any part of the Collateral directly in carrying on the Corporation's business or as security for loans or advances to enable the Collateral Agent to carry on the Corporation's business or otherwise; (d) receive the rents, incomes and profits of any kind whatsoever from the Collateral and pay therefrom: (i) any expenses of preserving, maintaining and completing the Collateral, of making such 29 - 29 - replacements thereof and improvements and additions thereto as the Collateral Agent may consider expedient and of carrying on all or any part of the Corporation's business relating to the Collateral; and (ii) any charges against the Collateral ranking in priority to or pari passu with the Security Interest or the payment of which may be necessary or desirable to preserve or protect all or any part of the Collateral or the interest of the Collateral Agent therein; (e) lease all or any part of the Collateral and renew from time to time all or any of the Leases on such terms and conditions as the Collateral Agent may determine; (f) with or without taking possession, take any action or proceedings to enforce the performance of any covenant contained in any of the Leases; (g) enjoy and exercise all the powers of the Corporation as the Collateral Agent considers necessary or desirable for the exercise of any and all of the remedies of the Collateral Agent provided for herein, including the powers to make any arrangement or compromise on behalf and in the name of the Corporation which the Collateral Agent considers expedient, to purchase on credit and borrow money on behalf and in the name of the Corporation and to advance moneys to the Corporation, all at such rates of interest as the Collateral Agent may consider reasonable, and to enter into contracts and undertake obligations on behalf of and in the name of the Corporation for any and all of the foregoing purposes or which the Collateral Agent considers necessary or desirable for the exercise of any of the rights, powers and remedies of the Collateral Agent provided for herein, all of which borrowings, advances and obligations together with interest thereon shall, at the discretion of the Collateral Agent, be entitled to the security hereof in priority to the payment of the Obligations; (h) sell or otherwise dispose of all or any part of the Collateral; (i) apply to a court for the appointment of a Receiver to take possession of all or such part of the Collateral as the Collateral Agent shall designate, with such duties, powers and obligations as the court making the appointment shall confer; (j) appoint a Receiver of all or any part of the Collateral by instrument in writing executed by the Collateral Agent; (k) institute proceedings in any court of competent jurisdiction for sale or foreclosure of the Collateral; and (l) take any steps or proceedings of any kind permitted by applicable Law or in equity or otherwise to enforce payment of the Obligations or performance of any other covenant or obligation of the Corporation contained herein, and exercise all rights and remedies of a secured party under the PPSA. 5.3 REMEDIES CUMULATIVE AND WAIVER. The rights and remedies hereunder of the Collateral Agent are cumulative and are in addition to and not in substitution for any other rights and remedies provided by law or by equity. Any single or partial exercise by the Collateral Agent of any right or remedy in respect of a default or breach of any term, covenant or condition contained herein shall not be deemed to be a waiver thereof or to alter, affect or prejudice any other right or remedy or other rights 30 - 30 - or remedies to which the Collateral Agent may be lawfully entitled, for such default or breach. The Collateral Agent shall at all times have the right to proceed against all or any portion of the Collateral or any other security in such order and in such manner as it shall determine without waiving any rights, powers or remedies which the Collateral Agent may have with respect to this Debenture or any other security or at law, in equity or otherwise. No delay or omission by the Collateral Agent in exercising any right, power or remedy hereunder or otherwise shall operate as a waiver thereof or of any other right, power or remedy. Any waiver by the Collateral Agent of the strict observance, performance or compliance with any term, covenant, condition or agreement herein contained and any indulgence granted, either expressly or by course of conduct, by the Collateral Agent shall be effective only in the specific instance and for the purpose of which it was given and shall be deemed not to be a waiver of any rights and remedies of the Collateral Agent hereunder as a result of any other default or breach hereunder. No consent or waiver by the Collateral Agent shall be effective unless made in writing and signed by an authorized officer of the Collateral Agent. 5.4 CONCERNING THE RECEIVER. (a) Any Receiver appointed by the Collateral Agent shall be vested with the rights and remedies which could have been exercised by the Collateral Agent in respect of the Corporation or the Collateral and such other powers and discretions as are granted in the instrument of appointment and any instrument or instruments supplemental thereto. The identity of the Receiver, any replacement thereof and any remuneration thereof shall be within the sole and unfettered discretion of the Collateral Agent. (b) Any Receiver appointed by the Collateral Agent shall act as agent for the Collateral Agent for the purposes of taking possession of the Collateral, but otherwise and for all other purposes (except as provided below) as agent for the Corporation. The Receiver may sell, lease, or otherwise dispose of the Collateral as agent for the Corporation or as agent for the Collateral Agent as the Collateral Agent may determine in its discretion. The Receiver shall apply all monies from time to time received by the Receiver in such order or priority, as the Collateral Agent may at their option direct. If there shall be a deficiency, the Corporation shall remain liable for such deficiency and shall pay the amount of such deficiency to the Collateral Agent forthwith. The balance of proceeds realized in respect of the Collateral, if any, remaining after repayment in full of the Obligations shall be paid to the Corporation or such other Person or Persons entitled thereto by applicable Law. The Corporation agrees to ratify and confirm all actions of the Receiver acting as agent for the Corporation, and to release and indemnify the Receiver in respect of all such actions. (c) The Collateral Agent, in appointing or refraining from appointing any Receiver, shall not incur liability to the Receiver, the Corporation or otherwise and shall not be responsible for any misconduct or negligence of such Receiver. 5.5 APPOINTMENT OF ATTORNEY. The Corporation hereby irrevocably appoints the Collateral Agent (and any of its officers) as attorney of the Corporation with full power of substitution to exercise, at any time when the Security Interest shall have become enforceable, in the name of and on behalf of the Corporation any of the Corporation's right, title and interest in and to the Collateral (including the right of disposal, execution, endorsement, delivery and transfer of all or any part of the Collateral). All acts of any such attorney are hereby ratified and approved, and such attorney shall not be liable for any 31 - 31 - act, failure to act or any other matter or thing in connection therewith, except for its own gross negligence or wilful misconduct. 5.6 DEALING WITH THE COLLATERAL AND THE SECURITY INTEREST. (a) The Collateral Agent shall not be obliged to exhaust its recourse against the Corporation or any other Person or Persons or against any other security the Collateral Agent may hold in respect of the Obligations before realizing upon or otherwise dealing with the Collateral in such manner as the Collateral Agent may consider desirable. (b) The Collateral Agent may grant extensions or other indulgences, take and give up securities, accept compositions, grant releases and discharges and otherwise deal with the Corporation and with other parties, sureties or securities as the Collateral Agent may see fit without prejudice to the Obligations or the rights of the Collateral Agent in respect of the Collateral. (c) The Collateral Agent shall not be: (i) liable or accountable for any failure to collect, realize or obtain payment in respect of the Collateral; (ii) bound to institute proceedings for the purpose of collecting, enforcing, realizing or obtaining payment of the Collateral or for the purpose of preserving any rights of the Collateral Agent, the Corporation or any other Person in respect thereof; (iii) responsible for any loss occasioned by any sale or other dealing with the Collateral or by the retention of or failure to sell or otherwise deal therewith; or (iv) bound to protect the Collateral from depreciating in value or becoming worthless. 5.7 STANDARDS OF SALE. Without prejudice to the ability of the Collateral Agent to dispose of the Collateral in any manner which is commercially reasonable, the Corporation acknowledges that a disposition of Collateral by the Collateral Agent which takes place substantially in accordance with the following provisions shall be deemed to be commercially reasonable: (a) Collateral may be disposed of in whole or in part; (b) Collateral may be disposed of by public auction, public tender or private contract, with or without advertising and without any other formality; (c) any purchaser or lessee of such Collateral may be a customer of the Collateral Agent, provided that such transaction is bona fide; (d) a disposition of Collateral may be on such terms and conditions as to credit or otherwise as the Collateral Agent, in its sole discretion, may deem advantageous; and (e) the Collateral Agent may establish an upset or reserve bid or price in respect of the Collateral. 5.8 DEALINGS BY THIRD PARTIES. No Person dealing with any of the Collateral Agent or its agent or a Receiver shall be required: (i) to determine whether the Security Interest has become enforceable; (ii) to determine whether the powers which the Collateral Agent or its agent is purporting 32 - 32 - to exercise have been exercisable; (iii) to determine whether any money remains due to the Collateral Agent by the Corporation; (iv) to determine the necessity or expediency of the stipulations and conditions subject to which any sale or lease shall be made; (v) to determine the propriety or regularity of any sale or any other dealing by the Collateral Agent with the Collateral; or (vi) to see to the application of any money paid to the Collateral Agent. The Security Interest is in addition to and not in substitution for any security now held or hereafter acquired by the Collateral Agent as security for the Obligations. 5.9 CORPORATION LIABLE FOR THE DEFICIENCY. In the case of any judicial or other steps or proceedings to enforce the Security Interest, and without limiting any right of the Collateral Agent to obtain judgment for any greater amount, the Corporation shall remain liable to the Collateral Agent for any amount which may remain due in respect of the Obligations after application to the payment thereof of the proceeds of any sale, lease or other disposition of the Collateral or any part thereof. 5.10 NOTICE OF SALE.

If the Collateral Agent is at any time or from time to time required to make a payment to defeat or honour the priority or possible priority of any Liens on or in respect of all or any part of the Collateral, any such payment or payments, and the costs, charges and expenses of the Collateral Agent in connection therewith (including legal fees on a solicitor and client basis) shall be payable by the Corporation on demand.

Each and every portion into which the Collateral is or may hereafter be divided does and shall stay charged with the Obligations. No Person shall have the right to require the Obligations to be apportioned and the Collateral Agent shall not be accountable to the Corporation for any moneys except those actually received by the Collateral Agent. 6.3 EXPENSES. The Corporation shall pay to the Collateral Agent on demand all of the costs, charges and expenses of the Collateral Agent (including legal fees on a solicitor and client basis and Receiver's fees) in connection with the preparation, registration or amendment of this Debenture, the perfection or preservation of the Security Interest, the enforcement by any means of any provision hereof 33 - 33 - or, after the occurrence of and during the continuance of a Default (as defined therein) of the nature set forth in Section 8.1.9 of the Term Loan Agreement or a Default (as defined therein) of the nature set forth in Section 501(10) of the Indenture, or an Event of Default (as defined in the Term Loan Agreement or the Indenture, as the case may be) the exercise of any rights, powers or remedies hereunder, including all such costs, charges and expenses in connection with taking possession, maintaining, completing, preserving, protecting, collecting or realizing upon all or any part of the Collateral or carrying on all or any part of the Corporation's business relating to the Collateral. 6.4 DISCHARGE OF DEBENTURE.

The Collateral Agent, the Administrative Agent and the Trustee shall execute and deliver to the Corporation such releases and discharges as the Corporation may reasonably require. 6.5 NO MERGER OF ESTATES. There shall not be deemed to be any merger of this Debenture, nor of the rights and interests of the Collateral Agent hereunder, with the estate in the Real Property or with the reversion or rights and interests of the Corporation or the Collateral Agent under any instrument affecting the Collateral by reason only of the fact that the same Person may own or acquire, directly or indirectly, two or more estates, rights or interests in the Collateral until all Persons having any interest under this Debenture, the estate in the Real Property or the reversion or rights and interests of the Corporation or the Collateral Agent under any instrument affecting the Collateral, by an appropriate instrument, so declare and provide. 6.6 NO OBLIGATION TO ADVANCE. Neither the issue nor delivery of this Debenture shall obligate the Collateral Agent, the Trustee, any Noteholder, the Administrative Agent or any Lender to advance any funds, or otherwise make or continue to make any credit available, to the Corporation. 6.7 [THIS SECTION HAS BEEN INTENTIONALLY DELETED.] 6.8 PERFECTION OF SECURITY. The Corporation shall register, file or record all financing statements and other documents in all offices where, in the opinion of the Collateral Agent, such registration, filing or recording is necessary or desirable to preserve, perfect or otherwise protect the Security Interest and the priority thereof. The Collateral Agent shall have the right to require that the form of this Debenture or any part thereof be amended to reflect any changes in applicable Law whether arising as a result of statutory amendments, court decisions or otherwise, in order to confer upon the Collateral Agent the security interest intended to be created by this Debenture, except that in no event shall the Collateral Agent require that any such amendment be effected if the result thereof would be to grant to the Collateral Agent greater rights than are otherwise contemplated herein. 6.9 ASSIGNMENTS AND PARTICIPATIONS. The Collateral Agent may sell, assign, transfer or otherwise dispose of all or any of the Obligations in accordance with the provisions governing the Obligations and, in such event, each and every immediate and successive assignee, transferee or holder of all or any of the Obligations, shall have, in respect of the rights or obligations sold, assigned, transferred or otherwise disposed of, the full benefit hereof to the same extent as if it were an original party to the Obligations or the part thereof so sold, assigned, transferred or otherwise disposed.

If, for the purposes of obtaining judgment in any court, it is necessary to convert any sum due, or owing to the Collateral Agent in any currency (the "Original Currency") into another currency (the "Other Currency"), the Corporation hereby agrees, to the fullest extent that it may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Collateral Agent could purchase the Original Currency with the Other Currency on the Business Day preceding that on which the final judgment is granted. The Obligations of the Corporation in respect of any sum due in the Original Currency from it to the Collateral Agent shall, notwithstanding any judgment in any Other Currency, be discharged only to the extent that on the Business Day following receipt by the Collateral Agent of any such sum adjudged to be so due or owing in such Other Currency, the Collateral Agent may in accordance with normal banking procedures purchase the Original Currency with such Other Currency. If the amount of the Original Currency so purchased is less than the sum originally due or owing to the Collateral Agent in the Original Currency, the Corporation shall, as a separate obligation and notwithstanding any such judgment, indemnify the Collateral Agent for the benefit of the Trustee, on its own account and on account of each Noteholder, and the Administrative Agent, on its own account and on account of each of the Lenders, against such loss, and if the amount of the Original Currency so purchased exceeds the sum originally due or owing to the Collateral Agent in the Original Currency, the Collateral Agent shall remit such excess to the Corporation. 35 6.15 COPY RECEIVED.
