other items required to be discharged by the Grantor during the year
immediately preceding the year during which such Event of Default occurred.
Such amounts shall be held by the Collateral Agent without interest to the
Grantor 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
   25
                                     - 25 -




Grantor 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 Grantor 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 7.14 shall affect any
right or remedy of the Collateral Agent under any provision of this Deed of
Hypothec 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 Grantor of its obligations to make or provide for the payment of
the annual taxes, assessments and other charges required to be discharged by
the Grantor under section 7.14.1.  All sums held pursuant to this section 7.14
shall form part of the Hypothecated Property.  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 7.14 to payment and performance of the
Obligations in accordance with the provisions of the Intercreditor and
Collateral Agency Agreement.  The Grantor 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.

                 7.14.3     Unless contested in accordance with the provisions 
of section 7.14.5, the Grantor 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 Hypothecated Property or any part thereof or the Rents
arising therefrom, or which might result in forfeiture of all or any part of
the Hypothecated Property.

                 7.14.4     The Grantor 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 Authority to operate
or use and occupy the Immovable Property and the Equipment for its intended uses
(collectively, the
   26
                                     - 26 -




"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 7.14.5, the Grantor
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 Hypothecated Property 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 Grantor shall not initiate or consent to any change in the
zoning, subdivision or any other use classification of the Lands, if such
action could have a material adverse effect on the hypothecs granted under of
this Deed of Hypothec or materially impair the present use and operation of the
Hypothecated Property or materially impair the Collateral Agent's rights or
benefits hereunder, without the prior written consent of the Collateral Agent.

                7.14.5           The Grantor may at its own expense contest the
amount or applicability of any of the obligations described in sections 7.14.1,
7.14.3 and 7.14.4 by appropriate legal proceedings, prosecution of which
operates to prevent the collection or enforcement thereof or the sale or
forfeiture of the Hypothecated Property or any part thereof to satisfy such
obligations; provided, however, that:

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

                7.14.5.2         in connection with such contest, the Grantor
shall have made provision for the payment or performance of such contested
obligation on the Grantor's books if and to the extent required by generally
accepted accounting principles then utilized by the Grantor 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 7.14.5:
   27
                                     - 27 -




                 7.14.5.3         no contest of any such obligations may be
pursued by the Grantor 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 Grantor 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

                 7.14.5.4         if at any time payment or performance of any
obligation contested by the Grantor pursuant to this section 7.14.5 shall
become necessary to prevent the delivery of a tax or similar deed conveying the
Hypothecated Property or any portion thereof because of nonpayment or
nonperformance, the Grantor shall pay or perform the same in sufficient time to
prevent the delivery of such tax or similar deed.

                 7.14.6           The Grantor shall, not in its use and
occupancy, of the Plant 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 Deed of Hypothec 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 the Plant or the Equipment and the Grantor
shall otherwise comply in all material respects with the requirements of any
insurer that issues a policy of insurance in respect of the Plant or the
Equipment.

                 7.14.7           The Grantor shall, promptly upon receipt of
any written notice regarding any failure by the Grantor to pay or discharge any
of the obligations described in section 7.14.1 or 7.14.6, furnish a copy of
such notice to the Collateral Agent.  The Grantor shall, promptly upon receipt
of any written notice regarding any failure by the Grantor to pay or discharge
any of the obligations described in section 7.14.3 or 7.14.4, furnish a copy of
such notice to the Collateral Agent, if such failure would have a Material
Adverse Effect.

                 7.15             CERTAIN TAX LAW CHANGES:  In the event of the
passage after the date of this Deed of Hypothec of any Law deducting from the
value of immovable property, for the purpose of taxation, amounts in respect of
any Lien thereon or changing in any way the Laws for the taxation of deeds of
hypothec or debts secured by deeds of
   28
                                     - 28 -




hypothec 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 Deed of Hypothec or the interest of any of the Collateral
Agent, the Administrative Agent, the Trustee, the Lenders and the Noteholders
in any Hypothecated Property (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 Grantor shall promptly pay the Collateral Agent such
amount or amounts as may be necessary from time to time to pay such tax.

                 7.16             REQUIRED INSURANCE POLICIES:

                 7.16.1           The Grantor shall maintain, or cause to be

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 the Plant is
located.  "Full replacement cost" means the cost of construction to replace the
Buildings and the Equipment, exclusive of depreciation, excavation, foundation
and footings, as determined from time to time by a proper officer of the
Grantor in consultation with its insurance company or insurance agent, as
appropriate;

                 7.16.1.2         Comprehensive general liability insurance
against claims for bodily injury, death or property damage occurring on, in or

covering any and all claims, including, without limitation, all legal
liability, subject to customary exclusions, to the extent insurable, imposed
upon the Collateral Agent or any of the Administrative Agent, Trustee, Lenders
or Noteholders, and all court costs and attorneys' fees, arising out of or
connected with the possession, use, leasing, operation or condition of the
Plant, with policy limits and deductibles in such amounts as would be
maintained by a prudent operator of property similar in use
   29
                                     - 29 -

located;

                 7.16.1.3         Comprehensive boiler and machinery insurance
to cover sudden and accidental breakdown, including but not limited to,

policy against claims for bodily injury, death and property damage covering all
owned, leased, non-owned and hired motor vehicles, including loading and
unloading in such amounts as would be maintained by a prudent operator of
property similar in use and configuration to the Plant and the Equipment and
located in the locality where the Plant is located;

                 7.16.1.5         Business interruption insurance on an annual
basis in amounts not less than the projected gross profit of the Plant during
the applicable twelve-month period but in no event less than the amount
necessary to pay the fixed charges and other expenses of owning, operating and
maintaining the Hypothecated Property for the same period;

                 7.16.1.6         To the extent not otherwise covered by the
insurance required under sections 7.16.1.1 and 7.16.1.2, during the performance
of any Alterations, renovations, repairs, restorations or construction, broad
form Builders Risk Insurance on an all-risk completed value basis; and

                 7.16.1.7         Such other insurance, against such risks and
with policy limits and deductibles in such amounts as would be maintained by a
prudent operator of property similar in use and configuration to the Plant and
located in the locality in which the Plant is located.

                 7.16.2           The Grantor may maintain the coverages
required by this section 7.16 under blanket policies covering the Plant and
other locations owned or operated by the Grantor if the terms of such blanket
policies otherwise comply with the provisions of this section 7.16 and contain
specific coverage allocations in respect of the Plant determined in accordance
with the provisions of this section 7.16.  All insurance
   30
                                     - 30 -




policies in respect of the coverages required by sections 7.16.1.1, 7.16.1.4,
7.16.1.6  and, if applicable, 7.16.1.7 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
and Collateral Agency Agreement, pursuant to a standard Canadian Insurance
Bureau standard mortgagee clause for use in the Province of Quebec, or any
equivalent thereof, and each such policy shall, to the extent obtainable at
commercially reasonable costs,

                 7.16.2.1         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 Grantor and
all rights of subrogation against any named insured, and

                 7.16.2.2         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 Grantor 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, 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 7.16.1.2, 7.16.1.5 and, if applicable, 7.16.1.7
shall name the Collateral Agent as an additional insured.

                 7.16.3           Each policy of insurance required under this
section 7.16 shall provide that:

                 7.16.3.1         notices of any failure by the Grantor to pay
any insurance premium in respect thereof, be furnished to the Collateral Agent
contemporaneously with any such notice given to the Grantor and

                 7.16.3.2         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
   31
                                      -31-




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 Grantor.  Settlement of any claim under any of the
insurance policies referred to in this section 7.16 (other than the insurance
contemplated in section 7.16.1.3 which in the Grantor'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 and Collateral Agency Agreement) and the
Grantor shall use its best efforts to cause each such insurance policy to
contain a provision to such effect.

                 7.16.4           At least fifteen (15) days prior to the
expiration of any insurance policy required by this section 7.16, the Grantor
shall deliver to the Collateral Agent evidence that such policy or policies
shall be renewed or extended and the Grantor shall deliver promptly to the
Collateral Agent after receipt thereof the policy or policies renewing or
extending such expiring policy or renewal or extension certificates or other
evidence of renewal or extension, together with a receipt showing payment of
the premium thereof.

                 7.16.5           The Grantor shall not purchase additional
policies in respect of the insurance coverages required to be maintained under
this section 7.16, unless the Collateral Agent is included thereon as an
additional named insured and, if applicable, with loss payable to the
Collateral Agent under an endorsement containing the provisions described in
section 7.16.2 and the policy evidencing such insurance otherwise complies with
the requirements of section 7.16.2.  The Grantor 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.

                 7.17             INSPECTION:  The Grantor shall permit the
Collateral Agent, by its agents, accountants and attorneys, to visit and
inspect the Hypothecated Property upon reasonable prior notice at such times as
may be reasonably requested by the Collateral Agent.

                 7.18             THE GRANTOR TO MAINTAIN IMPROVEMENTS:  The
Grantor shall not commit any waste on the Plant or with respect to any
Equipment or make any change in the use of the Plant or any Equipment.  The
Grantor represents and warrants that:
   32
                                      -32-


                 7.18.1           to the Grantor's knowledge, the Plant is
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 Grantor
have been obtained and duly recorded, and

                 7.18.2           the Grantor has access to the Plant from
public roads sufficient to allow the Grantor and its tenants and invitees to
conduct its and their businesses at the Plant as it is currently conducted.
The Grantor 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 and Collateral Agency Agreement, no Buildings
comprising a portion of the Plant may be demolished nor shall any Equipment be
removed without the prior written consent of the Collateral Agent.

                 7.19             LEASES:

                 7.19.1           All of the Leases are valid and effective in
accordance with their respective terms, except that the enforcement thereof may
be subject to:

                 7.19.1.1         bankruptcy, insolvency, reorganization,
moratorium or other similar Laws affecting or relating to enforcement of
creditors' rights generally, and

                 7.19.1.2         general equitable principles.

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

                 7.19.2           The Grantor shall manage and operate the
Hypothecated Property or cause the Hypothecated Property to be managed and
operated in a reasonably prudent manner and, except as otherwise permitted
under section 7.20, will not enter into any Lease (or any amendment or
modification thereof) or other agreement subsequent
   33
                                     - 33 -




to the date hereof with any Person which, in the reasonable judgment of the
Grantor, individually or in the aggregate, would have a Material Adverse Effect
on the value of the property subject thereto.

                 7.19.3           The Grantor shall not:

                 7.19.3.1         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
collected and received in advance in an amount not in excess of one (1) month's
rent and (ii) the Grantor may receive and collect escalation and other charges
in accordance with the terms of each Lease;

                 7.19.3.2         assign, transfer or hypothecate (other than
to the Collateral Agent hereunder or as otherwise permitted under section 7.20
of this Deed of Hypothec) any rental or other payment under any Lease whether
then due or to accrue in the future, the interest of the Grantor as lessor
under any Lease or the Rents, issues, revenues, profits or other income of the
Hypothecated Property;

                 7.19.3.3         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 Deed of Hypothec;

                 (ii)  such Lease has been hypothecated by the Grantor, as
                 landlord thereunder, to the Collateral Agent under this Deed
                 of Hypothec;

                 (iii)  in the case of any hypothecary recourse hereunder, 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
   34
                                     - 34 -




                 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 the exercise hereunder of any hypothecary
                 recourse in respect of any portion of the 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 the Plant, to the
                 successor owner upon the exercise hereunder of any hypothecary
                 recourse in respect of the Plant or the giving or granting of
                 a deed in lieu thereof; and

                 7.19.3.4         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 Grantor which, in the reasonable judgment of the Grantor,
individually or in the aggregate, would have a Material Adverse Effect or
materially impair the hypothecs created under this Deed of Hypothec unless:

                 (i)  the tenant under such Lease has not paid the equivalent
                 of two months' rent and the Grantor has made reasonable
                 efforts to collect such rent; or

                 (ii)  the Grantor shall deliver to the Collateral Agent an
                 officer's certificate to the effect that the Grantor 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 Grantor) sufficient to pay the
                 rent and other charges due
   35
                                     - 35 -




                 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.

                 7.19.4           The Grantor timely shall perform and observe
all the terms, covenants and conditions required to be performed and observed
by the Grantor 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 hypothecs created under this Deed of
Hypothec.  The Grantor promptly shall notify the Collateral Agent of the
receipt of any notice from any lessee under any Lease claiming that the Grantor
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 Grantor and
will cause a copy of each such notice to be delivered promptly to the
Collateral Agent.

                 7.20             TRANSFER RESTRICTIONS:  Except as otherwise
permitted by the Intercreditor and Collateral Agency Agreement, the Grantor
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
Hypothecated Property or suffer any of the foregoing to occur by operation of
Law or otherwise (each a "TRANSFER"); provided, however, the Grantor may so
encumber the Hypothecated Property 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 and are hereby
assigned and shall be paid to the Collateral Agent to be held in the Collateral
Account and disbursed pursuant to the Intercreditor and Collateral Agency
Agreement.

                 7.21             DESTRUCTION; CONDEMNATION:

                 7.21.1           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 Grantor 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
   36
                                     - 36 -




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 Grantor.  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 "INSURANCE PROCEEDS"), shall constitute Moneys and
be applied in accordance with the provisions of sections 7.21.3, 7.21.4 and
7.21.5.

                 7.21.2           If there shall occur any taking of the
Hypothecated Property or any part thereof, in or by condemnation or other
eminent domain proceedings pursuant to any Law, general or special, or by
reason of the temporary requisition of the use or occupancy of the Hypothecated
Property or any part thereof, by any Governmental Authority, civil or military
(each, a "TAKING"), the Grantor 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
Grantor.  The Grantor shall deliver or cause to be delivered to the Collateral
Agent all instruments requested by it to permit such participation.  The
Grantor shall in good faith and with due diligence file and prosecute what
would otherwise be the Grantor'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
Grantor 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 Grantor fails so to act, to file and
prosecute such claim.  The Grantor 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 Grantor.  The Grantor shall
take all steps necessary to notify the condemning authority of such assignment.
Such proceeds, award or payment paid to the Collateral
   37
                                     - 37 -




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 7.21.3, 7.21.4 and 7.21.5.

                 7.21.3           So long as no Event of Default shall have
occurred and be continuing, the Grantor shall have the right, at the Grantor's
option, to perform a restoration (a "RESTORATION") of the affected portions of
the Plant and the Equipment.  In the event the Grantor elects to perform a
Restoration, the Grantor 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 Grantor 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
Hypothecated Property shall be in the same condition and shall be of at least
equal utility for its intended purposes as the Hypothecated Property was
immediately prior to such Destruction or Taking.  The Grantor 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 and Collateral Agency Agreement.

                 7.21.4           In the event a Restoration is to be performed
under this section 7.21.4, the Collateral Agent shall not release any part of
the Net Award or the Insurance Proceeds except in accordance with the
provisions of section 7.21.5 and the Grantor 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:

                 7.21.4.1         complete plans and specifications (the "PLANS
AND SPECIFICATIONS") for the Restoration;
   38
                                     - 38 -





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

                 7.21.4.3         a certificate (an "ARCHITECT'S CERTIFICATE")
of an independent, reputable architect or engineer acceptable to the Collateral
Agent and licensed in the Province of Quebec (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

                 7.21.4.4         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 7.21.4.1 through 7.21.4.4 above, the Collateral
Agent shall acknowledge receipt of the Plans and Specifications.  Promptly upon
such acknowledgment of receipt by the Collateral Agent, the Grantor 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 Grantor 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.

                 7.21.5           In the event the Grantor performs a
Restoration of the Plant and Equipment as provided in section 7.21.4, 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 and Collateral Agency Agreement.  In the event there shall be any
surplus after application of the Net Award or the
   39
                                     - 39 -




Insurance Proceeds to Restoration of the Plant 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 and Collateral Agency Agreement.  Notwithstanding
anything to the contrary herein, if a Destruction or Taking of all or
substantially all of the Hypothecated Property 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 and Collateral Agency Agreement.

                 7.22             ALTERATIONS:  The Grantor shall not make any
material  structural addition, modification or change (each, an "ALTERATION")
to the Plant or the Equipment which would materially diminish the utility of
the Hypothecated Property or impair the hypothecs under this Deed of Hypothec.
Whether or not the Collateral Agent has consented to the making of any
Alteration, the Grantor 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 7.14.5.

                 7.23             HAZARDOUS MATERIAL:

                 7.23.1           Except with respect to those matters which
would not reasonably be expected to have a Material Adverse Effect, to the best
knowledge of the Grantor, the Grantor holds all Permits required to permit the
Grantor to conduct its business in the manner now conducted and none of the
Grantor'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 Grantor all such Permits
are valid and in full force and effect; and to the knowledge of the Grantor, no
suspension, cancellation, revocation or termination of any such Permit is
threatened.
   40
                                     - 40 -





                 7.23.2           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 Grantor, threatened, before
any Governmental Authority or before any arbitrator brought by or against the
Grantor or with respect to any of the Hypothecated Property the basis of which
is any Environmental Law.

                 7.23.3           The Grantor shall (or shall cause other
parties obligated to do so under or in accordance with contract or indemnity to
the Grantor):

                 7.23.3.1         take all commercially reasonable actions to
comply with any and all applicable present and future Environmental Laws
relating to the Plant;

                 7.23.3.2         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 Hypothecated Property
free of any Lien imposed pursuant to any Environmental Law;

                 7.23.3.3         take all commercially reasonable actions to
not Release any Hazardous Materials on, under or from the Hypothecated Property
in violation of any Environmental Law;

                 7.23.3.4         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

                 7.23.3.5         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 Grantor 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 Grantor's sole cost and
expense cause to be taken, any
   41
                                     - 41 -




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 Grantor.  Any costs or expenses incurred by the Collateral
Agent for such purpose shall be immediately due and payable by the Grantor and
shall bear interest at the Rate of Interest.  The Grantor shall provide to the
Collateral Agent and its agents and employees access to the Hypothecated
Property 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 Grantor 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 Hypothecated Property 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 Deed of Hypothec, 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 Grantor, to conduct an environmental audit or review of the Hypothecated
Property relating to the specific items as required in writing or relating to
the remedy that the Collateral Agent is exercising under this Deed of Hypothec
by persons or firms appointed by the Collateral Agent, and the Grantor shall
cooperate in all reasonable respects in the conduct of such environmental audit
or review, including, without limitation, by providing reasonable access to the
Hypothecated Property and to all records relating thereto.  The Grantor 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.

                 7.23.4           The Grantor may at its own expense contest
the amount or applicability of any of the obligations described in the first
   42
                                     - 42 -




sentence of section 7.23.3 by appropriate legal proceedings, prosecution of
which operates to prevent the enforcement thereof; provided, however, that:

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

                 7.23.4.2         in connection with such contest, the Grantor
shall have made provision for the payment or performance of such contested
obligation on the Grantor's books if and to the extent required by generally
accepted accounting principles then utilized by the Grantor 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 7.23.4, no contest of
any such obligations may be pursued by the Grantor 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 Grantor shall
have furnished an Additional Undertaking therefor satisfactory to the
Collateral Agent or for any civil liability for failure to comply with such
obligations.

                 7.24             ASBESTOS:  The Grantor shall not install nor
permit to be installed in the Hypothecated Property 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 Hypothecated Property, except with respect to
matters which would not have a Material Adverse Effect, the Grantor shall
comply with all Laws applicable to ACM located on the Plant, all at the
Grantor's sole cost and expense.  If the Grantor 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 Grantor and bear interest at the Rate of
Interest.  The Grantor shall provide to the Collateral Agent and its agents and
employees reasonable access to the Hypothecated Property upon reasonable prior
notice to remove such ACM if the Grantor fails to do so and removal is required
under any Environmental Law as provided
   43
                                     - 43 -




for above; provided, however, that nothing contained herein shall obligate the
Collateral Agent to exercise any rights under such access.  The Grantor 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.

                 7.25             BOOKS AND RECORDS; REPORTS:  The Grantor
shall keep proper books of record and account, which shall accurately represent
the financial condition of the Grantor and the business affairs of the Grantor
relating to the Hypothecated Property.  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 Grantor relating to the
operation of the Hypothecated Property at the office of the Grantor.

                 7.26             NO CLAIMS AGAINST THE COLLATERAL AGENT:
Nothing contained in this Deed of Hypothec 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 Grantor 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 hypothecs under this Deed of Hypothec.

                 7.27             UTILITY SERVICES:  The Grantor 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 Plant 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 7.18.

8.               DEFAULT:

                 8.1              EVENTS OF DEFAULT:  Each and every one of the
following events shall constitute an Event of Default under this Deed:

                 8.1.1            an Event of Default as defined in the Term
                   Loan Agreement;

                 8.1.2            an Event of Default as defined in the
                   Indenture; or

                 8.1.3            if any representation or warranty of the
Grantor made hereunder is or shall be incorrect when made in any material
respect;

                 8.1.4            if the Grantor shall default in the due
performance and observance of any of the Hypothec Obligations;

                 8.1.5            the publication of any prior notice of the
exercise of a hypothecary recourse, or a notice of crystallization as required
by the Civil Code of Quebec with respect to the Hypothecated Property or any
part thereof, unless same is being contested in good faith by appropriate legal
proceedings promptly instituted and diligently conducted, and provided there is
no immediate danger that such Hypothecated Property be taken in payment, be
taken for purposes of administration or be sold.


9.               EFFECTS OF DEFAULT:

                 9.1              RIGHTS UPON DEFAULT:  Upon the occurrence of
an Event of Default, the security hereby constituted shall become enforceable
and the Collateral Agent shall, in addition to any of its other rights,
forthwith be entitled to exercise any and all of the rights provided for in
this Deed and in Chapter V of Title III of Book VI of the Civil Code of Quebec
and in the Code of Civil Procedure of Quebec.  In exercising any of the rights
and recourses available hereunder or at Law, the Collateral Agent may, at its
option, in respect of all or any part of the Hypothecated Property, exercise
such rights and recourses as are available hereunder or at Law, as it chooses
to exercise, without prejudicing the Collateral Agent's other rights and
recourses available in respect of all or part of the other Hypothecated
Property.  Furthermore, the Collateral Agent may exercise any of its rights and
recourses in
   45
                                     - 45 -




respect of all or any part of the Hypothecated Property, simultaneously or
successively.  The Collateral Agent shall be entitled to acquire all or any
part of the Hypothecated Property, when permitted by Law.

                 9.2              PERFORMANCE:  The Collateral Agent shall be
entitled, in its discretion, to perform on behalf of the Grantor any of the
Grantor's obligations hereunder, should there be an Event of Default which has
occurred and is continuing with respect thereto.  In addition, the Collateral
Agent shall be entitled to do such things and make such reasonable expenditures
as it considers appropriate to enforce, preserve and protect its rights and
interests hereunder and the security constituted hereby.

                 9.3              NO WAIVER:  Any action taken by or on behalf
of the Collateral Agent to remedy any Event of Default shall not constitute a
waiver of such default, nor be deemed to have relieved the Grantor therefrom.
Failure of the Collateral Agent to insist upon strict performance of any
covenants of this Deed or to exercise any right or option hereunder shall not
be construed as a waiver or relinquishment for the future of any such covenant,
right or option.

                 9.4              RIGHTS CUMULATIVE:  The acceptance by the
Collateral Agent following the occurrence of any Event of Default or the
exercise by the Collateral Agent of any right or recourse hereunder or under
any other agreement between the Grantor and the Collateral Agent shall not
preclude the Collateral Agent from exercising any other right or recourse, all
rights and recourses of the Collateral Agent being cumulative and not
alternative.

                 9.5              SURRENDER:  If the Collateral Agent gives the
Grantor a prior notice of its intention to exercise a hypothecary right, the
Grantor shall, and shall cause any other Person in possession of the
Hypothecated Property, to immediately voluntarily surrender same to the
Collateral Agent.


10.              POSSESSION FOR PURPOSES OF ADMINISTRATION:

                 10.1             COLLATERAL AGENT'S RIGHTS:  In addition to
the rights available to the Collateral Agent under the Bond and the rights and
recourses upon default described in Article 9 hereof, in the event that the
   46
                                     - 46 -




Collateral Agent exercises the hypothecary right to take possession for
purposes of administration, the Collateral Agent shall have, in addition to the
rights and powers provided by Law as administrator entrusted with full
administration of the property of others, the rights and powers contained in
this Article 10.

                 10.2             ADMINISTRATION:  The Collateral Agent shall
have the right, after having fulfilled all formalities provided for at Law for
the exercise of its hypothecary right of taking possession for purposes of
administration, to enter into and take possession of, through its officers,
representatives, Receivers or other lawful attorney, all or any part of each of
the Hypothecated Property, with full power of a Person entrusted with full
administration of the property of others including the full power to administer
all or any part of each of the Hypothecated Property, with the full power to
(i) manage, operate, repair, alter, preserve, maintain or extend all or any
part of the Hypothecated Property, including, without limitation, the full
power to make any improvements or additions to the Hypothecated Property, or
any part thereof, as the Collateral Agent shall deem desirable or necessary
(provided that the Collateral Agent shall not be under any obligation to take
any action of any nature in connection with the Hypothecated Property or any
part thereof) and in connection therewith the power to enter into any contracts
or other agreements in respect of all or any part of the Hypothecated Property
in the name of and for the account of the Grantor, the Grantor expressly
authorizing the Collateral Agent to execute any and all such contracts or
agreements for, in the name of and on behalf of the Grantor, and the power to
cancel any contracts entered into by the Grantor or by the Collateral Agent on
its behalf and the power to renew any such contracts, in each case for such
term and subject to such provisions as the Collateral Agent shall deem

and generally the full right, power and authority to carry on the business of
the Grantor in connection with the Hypothecated Property in the place and stead
of the Grantor.  Furthermore, the Collateral Agent may, at its option, advance
its own moneys (and any such advance shall bear interest at the Rate of
Interest) for the payment of Taxes, wages and other charges or hypothecs, costs
or expenses ranking in priority to the Obligations or the security hereof and
other current operating expenses
   47
                                     - 47 -




incurred before or after such taking of possession, or for any other purpose
which the Collateral Agent deems necessary or advisable, but the Collateral
Agent shall not in any event be obliged to advance any such moneys and shall

elect not to do so.  Moneys so advanced shall be repaid by the Grantor on
demand and until repaid, shall bear interest at the Rate of Interest and be
secured by the hypothecs constituted hereby.  The Collateral Agent may borrow
money in connection with the business and affairs of the Grantor in connection
with the Hypothecated Property, in the name of and on behalf of the Grantor,

or any other obligations undertaken by the Collateral Agent pursuant hereto in
connection with the Hypothecated Property.

                 10.3             SURRENDER:  If the Collateral Agent exercises
its hypothecary right of taking possession for the purpose of administration,
the Grantor hereby binds and obliges itself to yield up possession of and
surrender the Hypothecated Property to the Collateral Agent on demand and
agrees to put no obstacles and not to hinder the rights and recourses of the
Collateral Agent, but to facilitate by all legal means, the actions of the
Collateral Agent hereunder and not to interfere with the powers hereby granted
to the Collateral Agent pursuant to this Deed and at Law.

                 10.4             DOCUMENTS:  If an Event of Default occurs and
is continuing, the Grantor shall forthwith by and through its officers and
directors execute such documents and transfers as may be necessary to place the
Collateral Agent in legal possession of any or all of the Hypothecated Property
in order to transfer the control of the administration to the Collateral Agent
and thereupon all the powers, functions, rights and privileges of each and
every of the directors and officers of the Grantor shall cease and determine
with respect to such Hypothecated Property unless specifically continued in
writing by the Collateral Agent for specific purposes.

and any such sale may be on such terms as to credit or otherwise and as to
upset price or reserve bid or price as the Collateral Agent in its sole
discretion may deem advantageous, and the Grantor agrees that the price
received at any such sale shall constitute a commercially reasonable price.

                 11.2             OTHER SALES:  The foregoing shall not
preclude the Collateral Agent from agreeing to sell, or making any sale in any
other manner not prohibited by Law nor shall it be interpreted to mean that

Law, in accordance with the provisions of the Intercreditor and Collateral
Agency Agreement, the Term Loan Agreement or the Indenture in respect of the

usage or custom to the contrary, including Article 2743 of the Civil Code of
Quebec, receipt by the Collateral Agent (or by the Grantor as agent for the
Collateral Agent) of any Claims, Rents or Immovable Claims shall not operate as
payment of any Obligations unless the Collateral Agent expressly applies the
amounts so received in reduction of such Obligations in accordance with this
Deed and to the extent only of such application.

14.              APPOINTED ATTORNEY OF THE GRANTOR:  The Grantor hereby
irrevocably nominates, constitutes and appoints the Collateral Agent and any
Person further designated by the Collateral Agent, upon the occurrence of an
Event of Default which is continuing, to be the lawful attorney-in-fact and
mandatary of the Grantor for and in the name and on behalf of the Grantor to
execute and do any deeds, documents, transfers, demands, conveyances,
assignments, assurances, consents and things which the Grantor ought to sign,
execute or do hereunder and to commence, continue and defend any proceedings
authorized to be taken hereunder and generally to use the name of the Grantor
in the exercise of all or any of the powers hereby conferred on the Collateral
Agent and any agent appointed hereunder.


15.              REMEDIES CUMULATIVE:  No remedy, right or recourse of the
Collateral Agent conferred or reserved hereunder is intended to be exclusive of
any other remedy, right or recourse under this Deed, under any other security
or at Law, but each and every such remedy shall be cumulative, and shall be in
addition to every other remedy, right or recourse given hereunder or now
existing or hereafter to exist by contract or by Law.  The exercise by the
Collateral Agent of any right, remedy or recourse available to it pursuant to
this Deed or at Law shall not
   50
                                     - 50 -




preclude the Collateral Agent from exercising any other right, remedy or
recourse at any time or from time to time.


16.              JUDGMENT FOR AMOUNTS REMAINING DUE:  In the case of any
judicial or other proceedings to enforce the security hereby constituted, and
without limiting any right of the Collateral Agent to obtain judgment for any
greater amount, judgment may be rendered against the Grantor in favour of the
Collateral Agent for any amount which may remain due in respect of the
Obligations after the application to the payment thereof of the proceeds of any
sale of all or part of each of the Hypothecated Property or any or all of them
or any additional security therefor.


17.              PAYMENTS TO THIRD PARTIES:  If the Collateral Agent is at any

Collateral Agent shall be secured hereby.


18.              OTHER PROVISIONS CONCERNING THE
                 COLLATERAL AGENT:  By way of supplement to the provisions of

exercise thereof, whether in relation to the manner or as to the mode and time
for the exercise thereof;

                 18.2             Neither the Collateral Agent nor any agent or
Receiver appointed by it shall be responsible or liable, otherwise than for any

Agent or such agent or Receiver shall manage the Hypothecated Property or any
part thereof upon or after entry as herein
   51
                                     - 51 -




provided and the Collateral Agent shall not be bound to do, observe or perform
or to see to the observance or performance by the Grantor of any of the

right comprised therein);

                 18.3             In the event of any sale in accordance with

Receiver or under judicial proceedings, the Grantor shall execute and deliver
to the purchaser on demand any instrument or assurance reasonably necessary to
confirm to the purchaser the title of the property so sold and, in the case of
any such sale, the Collateral Agent is hereby irrevocably authorized by the
Grantor to execute on its behalf any such confirmatory instrument or assurance;

                 18.4             No Person dealing with the Collateral Agent
or its agents or any Receiver shall be concerned to inquire whether the powers
which the Collateral Agent or such agents or Receiver are purporting to
exercise have become exercisable, or whether any money remains due on the
security of this Deed, or as to the necessity or expediency of the stipulations
and conditions subject to which any sale shall be made, or otherwise as to the
propriety or regularity of any sale or of any other dealing by the Collateral
Agent or such agents or Receiver with the Hypothecated Property or to see to
the application of any money paid to the Collateral Agent or such agents or
Receiver.  In the absence of fraud on the part of such Person, such dealings
shall be deemed, insofar as regards the safety and protection of such Person,
to be within the powers hereby conferred and to be valid and effectual
accordingly;

                 18.5             Subject to applicable Laws, no delay or
omission of the Collateral Agent to exercise any right or power accruing upon
any Event of Default shall impair such right or power, or shall be construed to
be a waiver of any such Event of Default or an acquiescence therein and every
power and remedy given hereby to the Collateral Agent may be exercised by it
from time to time and as often as may be deemed expedient by it.

                 18.6             The Collateral Agent may invest any Person

the powers and discretion of the Collateral Agent hereunder;

                 18.6.3           the Collateral Agent may from time to time

employee of the Collateral Agent;

                 18.6.5           the engagement or appointment of every such
Person by the Collateral Agent shall not create any liability on the part of
the Collateral Agent to such Person in any respect and such engagement,
appointment or delegation or anything which may be done by any such Person or
the removal of any Person or the termination of any such appointment or
engagement shall not have the effect of creating any liability of any nature
whatsoever of any such Person towards the Collateral Agent;

                 18.6.6           every such Person shall from time to time
have the power to operate, in accordance with normal practice, all or any part

Agent may determine, and obtain security therefor upon the Hypothecated
