                          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 lender 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 lender's judgment, be insufficient
                          (when added to the installments anticipated to be
                          paid thereafter) to discharge any of such obligations
                          when due, the corporation shall, immediately upon
                          demand, deposit with the lender such additional
                          amounts as may be requested by the lender.  Nothing
                          contained in this paragraph 12(n) shall affect any
                          right or remedy of the lender 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 lender 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 paragraph
                          12(n)(i).  All sums held pursuant to this paragraph
                          12(n) shall form part of the Collateral.  During the
                          continuance of any Event of Default, the lender may
                          apply all or any part of the sums held pursuant to
                          this paragraph 12(n) to payment and performance of
                          the Obligations in accordance with the provisions of
                          the Intercreditor Agreement.  The corporation shall
                          redeposit with the lender 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.

                 (iii)    Unless contested in accordance with the provisions of
                          paragraph 12(n)(v), 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.

                 (iv)     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 paragraph 12(n)(v), the corporation
                          shall comply promptly with, or cause
   19
                                       12

                          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
                          lender's rights or benefits hereunder, without the
                          prior written consent of the lender.

                 (v)      The corporation may at its own expense contest the
                          amount or applicability of any of the obligations
                          described in 12(n)(i), 12(n)(iii) and 12(n)(iv) 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:

                          aa)     any such contest shall be conducted in good
                                  faith by appropriate legal proceedings
                                  promptly instituted and diligently conducted;
                                  and

                          bb)     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 lender a sum sufficient to pay and
                                  discharge such obligation and the lender's
                                  estimate of all interest and penalties
                                  related thereto.

                                  Notwithstanding the foregoing provisions of
                                  this paragraph 12(n)(v):

                          cc)     no contest of any such obligations may be
                                  pursued by the corporation if such contest
                                  would expose the lender, 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
                                  lender in respect of any civil liability for
                                  failure to comply with such obligations;  and

                          dd)     if at any time payment or performance of any
                                  obligation contested by the corporation
                                  pursuant to this paragraph 12(n)(v) 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.

                                       13

                 (vi)     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 defence 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.

                 (vii)    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 paragraph 12(n)(i) or
                          12(n)(vi), furnish a copy of such notice to the
                          lender.  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 paragraph 12(n)(iii) or
                          12(n)(iv), furnish a copy of such notice to the
                          lender, if such failure would have a Material Adverse
                          Effect.

         (o)     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 lender,
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 lender such amount or amounts as may be
necessary from time to time to pay such tax.

         (p)     REQUIRED INSURANCE POLICIES.

                 (i)      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

                                  Equipment, with such deductibles as would be

                                  is located.  "Full replacement cost" means

                                  footings, as determined from time to time by
                                  a proper officer of the corporation in
                                  consultation with its insurance company or

                                  of the Plants and any adjoining streets,
                                  sidewalks and passageways and covering any

                                  insurable, imposed upon the lender or any of
                                  the Administrative Agent, Trustee, Lenders or

                                  would be maintained by a prudent operator of
                                  property similar in use and configuration to
                                  the Plant and located in the locality where

                          roads sufficient to allow the corporation and its
                          tenants and invitees to conduct its and their

                          To the corporation's knowledge, the corporation is
                          not in material breach of or in default (and to the

                          with due notice or lapse of time or both, may
                          constitute such a material breach or default) under

                          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.

                 (ii)     The corporation shall mange and operate the
                          Collateral or cause the Collateral to be managed and
                          operated in a reasonably prudent manner and, except

                          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.

                 (iii)    The corporation shall not:

                          (aa)    receive or collect, or permit the receipt or

                                  advance of the respective period in respect
                                  of which they are to accrue, except that (i)

                                  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:

                                  (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
                                           lender 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
   26
                                       19

                                           the amount which would have then been
                                           payable under the terminated or
                                           assigned Lease.

                 (iv)     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 lender 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
                          lender.

         (t)     TRANSFER RESTRICTIONS.  Except as otherwise permitted by the
Intercreditor Agreement, the corporation shall not, without the prior written
consent of the lender, 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
lender to be held in the Collateral Account (as defined in the Intercreditor
Agreement) and disbursed pursuant to the Intercreditor Agreement.

         (u)     DESTRUCTION; EXPROPRIATION.

                 (i)      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 lender 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 lender 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
                          lender 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 "INSURANCE PROCEEDS"), shall
                          constitute Moneys and be applied in accordance with
                          the provisions of paragraphs 12(u)(iii) , 12(u)(iv)
                          and (12(u)(v).

                 (ii)     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 lender upon receiving notice of such Taking or
                          commencement of proceeding therefor.  The lender may
                          (but shall not be obligated to) participate in any
                          proceedings or negotiations which might result in any
                          Taking.  The lender may be represented by counsel
                          satisfactory to it at
   27
                                       20

                          the expense of the corporation.  The corporation
                          shall deliver or cause to be delivered to the lender
                          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 lender, and hereby irrevocably
                          authorizes and empowers the lender, 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 lender 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 lender
                          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 lender, 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
                          paragraphs 12(u)(iii), 12(u)(iv) and 12(u)(v).

                 (iii)    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 lender within twenty (20) business
                          days after the date that the lender 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 lender does not
                          receive a Restoration Election Notice within such
                          twenty (20) business day period, the lender shall
                          deal with such Insurance Proceeds or Net Award in
                          accordance with the provisions of the Intercreditor
                          Agreement.

                 (iv)     In the event a Restoration is to be performed under
                          this paragraph 12(u)(iv), the lender shall not
                          release any part of the Net Award or the Insurance
                          Proceeds except in accordance with the provisions of
                          paragraph 12(u)(iii) and the corporation shall, prior
                          to commencing any work to
   28
                                       21

                          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 lender:

                          (aa)    complete plans and specifications (the "PLANS
                                  AND SPECIFICATIONS") for the Restoration;

                          (bb)    an officers' certificate stating that all
                                  permits and approvals required by Law to
                                  commence work in connection with the
                                  Restoration have been obtained;

                          (cc)    a certificate (an "ARCHITECT'S CERTIFICATE")
                                  of an independent, reputable architect or
                                  engineer acceptable to the lender and
                                  licensed in the Province of New Brunswick (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

                          (dd)    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 lender for
                                  application toward the cost of such
                                  Restoration.

                          Upon receipt by the lender of each of the items
                          required pursuant to paragraphs 12(u)(iv)(aa) through
                          12(u)(iv)(dd) above, the lender shall acknowledge
                          receipt of the Plans and Specifications.  Promptly
                          upon such acknowledgement of receipt by the lender,
                          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.

                 (v)      In the event the corporation performs a Restoration
                          of any of the Plants and Equipment as provided in
                          paragraph 12(u)(iv), the lender shall apply any
                          Insurance Proceeds or Net Award held by the lender 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
                          lender to the payment of the Obligations, in
                          accordance with Article 6 of the Intercreditor
   29
                                       22

                          Agreement.  Notwithstanding anything to the contrary
                          herein, if a Destruction or Taking of all or
                          substantially all of the Collateral 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.

         (v)     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 lender 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 paragraph 12(n)(v).

         (w)     HAZARDOUS MATERIAL.

                 (i)      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.

                 (ii)     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.

                 (iii)    The corporation shall (or shall cause other parties
                          obligated to do so under or in accordance with
                          contracts with or indemnity to the corporation):

                          (aa)    take all commercially reasonable actions to
                                  comply with any and all applicable present
                                  and future Environmental Laws relating to the
                                  Plants;

                                  removal, response measure or corrective

                                  agreement or instrument and keep the
                                  Collateral free of any Lien imposed pursuant
                                  to any Environmental Law;
   30
                                       23

                          (cc)    take all commercially reasonable actions to
                                  not Release any Hazardous Materials on, under
                                  or from the Collateral in violation of any
                                  Environmental Law;

                                  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

                          (ee)    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 lender, 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
                                  lender may (upon receipt of an indemnity
                                  satisfactory to the lender), 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 lender
                                  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 lender 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 lender,
                                  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 lender,
                                  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 any time that the
                                  lender is exercising its remedies under this
                                  Debenture, the lender shall have the right
                                  (upon receipt of an indemnity satisfactory to
                                  the lender), 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 lender is exercising
                                  under this Debenture by persons or firms
                                  appointed by the lender, and the lender 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 lender, 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 lender,
   31
                                       24

                                  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 lender,
                                  Administrative Agent, Trustee, Lenders and
                                  Noteholders being deemed an "owner" or
                                  "operator" under applicable Environmental
                                  Law.

                 (iv)     The corporation may at its own expense contest the
                          amount or applicability of any of the obligations
                          described in the first sentence of paragraph
                          12(w)(iii) by appropriate legal proceedings,
                          prosecution of which operates to prevent the
                          enforcement thereof;  provided, however, that:

                          (aa)    any such contest shall be conducted in good
                                  faith by appropriate legal proceedings
                                  promptly instituted and diligently conducted;
                                  and

                          (bb)    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 lender a sum sufficient to pay and
                                  discharge such obligation and the lender's
                                  estimate of all interest and penalties
                                  related thereto.  Notwithstanding the
                                  foregoing provisions of this paragraph
                                  12(w)(iv), no contest of any such obligations
                                  may be pursued by the corporation if such
                                  contest would expose the lender, 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 lender for any
                                  civil liability for failure to comply with
                                  such obligations.

         (x)     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 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' sole
cost and expense.  If the corporation shall fail so to comply with such Laws,
the lender may (upon receipt of an indemnity satisfactory to the lender) 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 lender 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 lender 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
lender to exercise any rights under such access.  The corporation shall
indemnify and hold each of the lender, Administrative Agent, Trustee, Lenders
and Noteholders harmless from and against all loss, cost, damage and expense
that any of the lender, Administrative Agent, Trustee, Lenders and Noteholders
may sustain as a result of the presence of any ACM and any removal thereof in
   32
                                       25

compliance with any applicable Environmental Law.

         (y)     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 lender 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.

         (z)     NO CLAIMS AGAINST THE LENDER.  Nothing contained in this
Debenture shall constitute any consent or request by the lender, 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 lender 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.

         (aa)    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
paragraph 12(r).

DEFAULT

13.              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 lender without the 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.

REMEDIES

14.              Whenever the Security Interest has become enforceable, the
lender 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 lender 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 lender 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
   33
                                       26

business or as security for loans or advances to enable the lender 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 replacements thereof
and improvements and additions thereto as the lender 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 lender 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 lender 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
lender considers necessary or desirable for the exercise of any and all of the
remedies of the lender provided for herein, including the powers to make any
arrangement or compromise on behalf and in the name of the corporation which
the lender 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 lender 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 lender considers necessary or desirable for the exercise of any of
the rights, powers and remedies of the lender provided for herein, all of which
borrowings, advances and obligations together with interest thereon shall, at
the discretion of the lender, 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 lender 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 lender;

         (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, including without limitation the powers conferred upon a mortgagee
under the Property Act (New Brunswick), and exercise all rights and remedies of
a secured party under the PPSA.

REMEDIES CUMULATIVE AND WAIVER

15.              The rights and remedies hereunder of the lender 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
lender 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
   34
                                       27

be a waiver thereof or to alter, affect or prejudice any other right or remedy
or other rights or remedies to which the lender may be lawfully entitled, for
such default or breach.  The lender 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 lender may have with respect to this Debenture or
any other security or at law, in equity or otherwise.  No delay or omission by
the lender 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 lender 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 lender 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
lender hereunder as a result of any other default or breach hereunder.  No
consent or waiver by the lender shall be effective unless made in writing and
signed by an authorized officer of the lender.

CONCERNING THE RECEIVER

16.      (a)     Any Receiver appointed by the lender shall be vested with the
rights and remedies which could have been exercised by the lender 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 lender.

         (b)     Any Receiver appointed by the lender shall act as agent for
the lender 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 lender as the
lender 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
lender may at its 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 lender 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 lender, 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.

APPOINTMENT OF ATTORNEY

17.              The corporation hereby irrevocably appoints the lender (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 and 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 act, failure to act
or any other matter or thing in connection therewith, except for its own gross
negligence or wilful misconduct.
   35
                                       28

DEALING WITH THE COLLATERAL AND THE SECURITY INTEREST

18.      (a)     The lender shall not be obliged to exhaust its recourse
against the corporation or any other Person or Persons or against any other
security the lender may hold in respect of the Obligations before realizing
upon or otherwise dealing with the Collateral in such manner as the lender may
consider desirable.

         (b)     The lender 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 lender may see fit without prejudice to the Obligations or
the rights of the lender in respect of the Collateral.

         (c)     The lender 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 lender 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.

STANDARDS OF SALE

19.              Without prejudice to the ability of the lender to dispose of
the Collateral in any manner which is commercially reasonable, the corporation
acknowledges that a disposition of Collateral by the lender 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 lender, 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 lender, in its sole discretion, may
deem advantageous; and

         (e)     the lender may establish an upset or reserve bid or price in
respect of the Collateral.

DEALINGS BY THIRD PARTIES

20.              No person dealing with any of the lender 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 lender or
its agent is purporting to exercise have been exercisable; (iii) to determine
whether any money remains due to the lender 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 lender with the
Collateral; or (vi) to see to the application of any money paid to the lender.
The Security Interest is in addition to and not in substitution for any
security now held or hereafter acquired by the lender as security for the
Obligations.
   36
                                       29

CORPORATION LIABLE FOR THE DEFICIENCY

21.              In the case of any judicial or other steps or proceedings to
enforce the Security Interest, and without limiting any right of the lender to
obtain judgment for any greater amount, the corporation shall remain liable to
the lender 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.

NOTICE OF SALE

22.              Unless required by applicable Law, neither the lender nor any
Receiver appointed by it shall be required to give the corporation any notice
of any sale, lease or other disposition of the Collateral or any part thereof
or the date after which any private disposition of Collateral or any part
thereof is to be made.

PAYMENT OF PRIOR CLAIMS

23.              If the lender 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 lender in connection
therewith (including legal fees on a solicitor and client basis) shall be
payable by the corporation on demand.

NOTICE

24.              Any and all demands, notices or other communications to be
made or given pursuant to this Debenture shall be given and received in the
manner and at the addresses specified in Section 11.2 of the Intercreditor
Agreement.

RELEASES

25.              Subject to the provisions of the Term Loan Agreement and the
Indenture, the lender may in its discretion, from time to time, release any
part of the Collateral or any other security held by the lender either with or
without any sufficient consideration therefor, without responsibility therefor
and without thereby releasing any other part of the Collateral or any other
security or any Person from the security created by this Debenture or from any

upon all or any part of the Collateral or carrying on all or any part of the
corporation's business relating to the Collateral.

DISCHARGE OF DEBENTURE

The lender, the Administrative Agent and the Trustee shall execute and deliver
to the corporation such releases and discharges as the corporation may
reasonably require.

NO MERGER OF ESTATES

or the lender 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 lender under any
instrument affecting the Collateral, by an appropriate instrument, so declare
and provide.

NO OBLIGATION TO ADVANCE

29.              Neither the issue nor delivery of this Debenture shall

any Lender to advance any funds, or otherwise make or continue to make any
credit available, to the corporation.

PERFECTION OF SECURITY

30.              The corporation shall register, file or record all financing
statements and other documents in all offices where, in the opinion of the
lender, such registration, filing or recording is necessary or desirable to
preserve, perfect or otherwise protect the Security Interest and the priority
thereof.  The lender 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 lender the security interest intended to
be created by this Debenture, except that in no event shall the lender require
that any such amendment be effected if the result thereof would be to grant to
the lender greater rights than are otherwise contemplated herein.

ASSIGNMENTS AND PARTICIPATIONS

31.              The lender 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 of, without regard to any set-off,
counterclaim or equities between the corporation and the lender.  None of the
rights or obligations hereunder of the corporation may be assigned without the
prior written consent of the lender, except in accordance with the provisions
of the Intercreditor Agreement.

corporation and the lender.

FURTHER ASSURANCES

after the Security Interest shall have become enforceable, at its sole cost and
expense, do all such acts and things and execute and deliver all such deeds,
transfers, assignments and instruments as the lender may reasonably require for
protecting the Collateral or perfecting the Security Interest and for
exercising all powers, authorities and discretions hereby conferred upon the
lender and the corporation shall, from time to time after the Security Interest
has become enforceable, at its sole cost and expense, do all such acts and
things and execute and deliver all such deeds, transfers, assignments and
instruments as the lender may require for facilitating the sale of the
Collateral in connection with any realization thereof.

JUDGMENT CURRENCY

36.              If, for the purposes of obtaining judgment in any court, it is
necessary to convert any sum due, or owing to the lender 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 lender 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 lender shall, notwithstanding any
judgment in any Other Currency, be discharged only to the extent that on the
Business Day following receipt by the lender of any such sum adjudged to be so
due or owing in such Other Currency, the lender 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 lender in the Original Currency, the corporation
shall, as a separate obligation and notwithstanding any such judgment,
indemnify the lender 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 lender in the Original Currency, the lender shall remit such excess to the
corporation.

37.              The corporation acknowledges receipt of a copy of this
Debenture.
