(j)                                     the Collateral Agent may borrow money on the security

the Charged Property whether or not in priority to the Charge; and

 

(k)                                  the Collateral Agent may exercise any other right or

In addition to the remedies set forth in Section 4.2
and elsewhere in this Debenture, whenever the Charge is enforceable, the
Collateral Agent may:

 

(a)                                  redeem any prior Lien against any Charged Property,
procure the transfer of such Lien to itself, or settle and pass the accounts of
the prior mortgagee, chargee or encumbrancer (any accounts to be conclusive and
binding on the Obligor);

 

(b)                                 pay any liability secured by any Lien against any
Charged Property or discharge any Lien that may exist or be threatened against
the Charged Property (the Obligor will promptly upon receipt of written notice
reimburse the Collateral Agent for all such payments);

 

(c)                                  to facilitate the realization of the Charged Property,
enter upon, occupy and use all or any of the premises, buildings and plant
comprising the Charged Property and use all or any of the equipment and other
personal property of the Obligor for such time as the Collateral Agent requires
to facilitate such realization, free of charge (as between the Obligor and the

for any act, omission or neglect in so doing or in respect of any rent,
charges, depreciation or damages incurred in connection with such actions;

 

(d)                                 borrow for the purpose of carrying on the business of

on any private sale, bid for and purchase any or all of the Charged Property
offered for sale and upon

 

14

 

compliance with the terms of such sale, hold,
retain and dispose of such Charged Property without any further accountability
to the Obligor or any other Person with respect to such holding, retention or
disposition, except as required by law. 
In any such sale to the Collateral Agent, the Collateral Agent may, for
the purpose of making payment for all or any part of the Charged Property so
purchased, use any claim for Secured Obligations then due and payable to it as
a credit against the purchase price.

 

Section 4.4                                               Exercise of Remedies.

 

The remedies under Section 4.2 and Section 4.3
may be exercised from time to time separately or in combination and are in
addition to, and not in substitution for, any other rights of the Collateral
Agent and the Secured Creditors however arising or created.  The Collateral Agent and the Secured
Creditors are not bound to exercise any right or remedy, and the exercise of
rights and remedies is without prejudice to the rights of the Collateral Agent
and the Secured Creditors in respect of the Secured Obligations including the
right to claim for any deficiency.

 

Section 4.5                                               Appointment of Attorney.

 

The Obligor irrevocably appoints the Collateral
Agent (and each of its officers) as attorney of the Obligor (with full power of
substitution) to do, make and execute in the name of and on behalf of the
Obligor, upon (and only upon) the Charge becoming enforceable, all such further
acts, documents, matters and things which the Collateral Agent may reasonably
deem necessary or advisable to accomplish the purposes of this Debenture for
the recovery of all fees, tariffs and other sums of money that may become or
are now due or owing to the Obligor in respect of the Charged Property and for
the enforcement of all contracts, covenants or conditions binding on any lessee
or occupier of the Charged Property or on any Person in respect of it, and this
appointment shall take effect if the Charge has become enforceable, subject to
all applicable laws.  The Collateral
Agent or its nominees and transferees are empowered to exercise all rights and
powers and to perform all acts of ownership with respect to the Charged
Property and to deal with the Charged Property, to the same extent as the
Obligor might do.  All acts of any such
attorney are hereby ratified and approved, and the 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.

 

Section 4.6                                   Dealing with the Charged Property.

 

(1)                                  Except as otherwise provided by law or this Debenture,
neither the Collateral Agent, the Secured Creditors, any Receiver nor any agent
of any of them (including any civil enforcement agent) shall be: (i) liable
or accountable for any failure to collect, realize or obtain payment in respect
of the Charged Property; (ii) bound to institute proceedings for the
purpose of collecting, enforcing, realizing or obtaining payment of the Charged
Property or for the purpose of preserving any rights of any Persons; (iii) responsible
for any loss occasioned by any sale or other dealing with the Charged Property
or by the retention of or failure to sell or otherwise deal with the Charged
Property; or (iv) bound to protect the Charged Property from depreciating
in value or becoming worthless.

 

15

 

(2)                                  The Collateral Agent and the Secured Creditors may
grant extensions or other indulgences, take and give up securities, accept
compositions, grant releases and discharges and otherwise deal with the Obligor
and with other Persons, sureties or securities as they may see fit without
prejudice to the Secured  Obligations,
the liability of the Obligor or the rights of the Secured Creditors in respect
of the Charged Property.

 

(3)                                  Neither the Collateral Agent nor the Secured Creditors
shall be obliged to exhaust their recourse against the Obligor or any other
Person  or against any other
security they may hold in respect of the Secured  Obligations before realizing upon or otherwise dealing with
the Charged Property in such manner as the Collateral Agent may consider
desirable.

 

Section 4.7                                   Status of the Receiver.

 

(1)                                  Subject to all applicable laws, any Receiver appointed
by the Collateral Agent is vested with the rights and remedies which could have
been exercised by the Collateral Agent in respect of the Obligor or the Charged
Property and such other powers and discretions as are granted in the instrument
of appointment and any supplemental instruments including, without limitation,
any or all of the powers of the Collateral Agent or of the officer of the
Collateral Agent referred to above.  The
identity of the Receiver, its replacement and its remuneration are within the
sole and unfettered discretion of the Collateral Agent.

 

(2)                                  The Receiver shall, for all purposes relating to the
Receiver’s acts or defaults and remuneration, be deemed to be the agent of the
Obligor and not of the Collateral Agent or any of the Secured Creditors, and
the Obligor shall be solely responsible for the Receiver’s acts or defaults and
remuneration.  The Receiver may sell,
lease, or otherwise dispose of Charged Property as agent for the Obligor or as
agent for the Collateral Agent or the Secured Creditors as the Collateral Agent
may determine in its discretion.

 

(3)                                  All amounts from time to time received by the
Collateral Agent or the Receiver may (but need not) be applied in the following
order: (i) in discharge of all operating expenses and other outgoings
affecting the Charged Property; (ii) in keeping in good standing all Liens
on the Charged Property having priority over the Charge; (iii) in payment
of the remuneration and disbursements of the Receiver (if any); (iv) in
payment to the Collateral Agent of the amounts payable hereunder; (v) to
such reserves against potential claims that the Collateral Agent or the
Receiver in good faith believes should be maintained, until such potential
claims are settled, and the balance, if any, shall be paid in accordance with
the provisions of Section 5.14.

 

(4)                                  The Collateral Agent, in appointing or refraining from
appointing any Receiver, does not incur liability to the Receiver, the Obligor
or otherwise and is not responsible for any misconduct or negligence of such
Receiver.

 

16

 

Section 4.8                                   Powers of Privately Appointed
Receiver.

shall, to the extent permitted by law, have power to:

of the Charged Property and, for that purpose, to take proceedings in the name
of the Obligor or otherwise, and to make any arrangement or compromise;

 

(b)                                 from time to time and without any previous notice or
demand and free of charge, enter upon or into and occupy and use all or any
part of the premises, buildings, plant and undertaking of or occupied or used
by the Obligor without being or being deemed to be a mortgagee in possession;

 

(c)                                  carry on or concur in carrying on all or any part of
the business of the Obligor;

Charged Property in priority to this Debenture or otherwise for such purposes
as may be approved by the Collateral Agent; and

 

(e)                                  sell or lease or concur in selling or leasing all or
any part of the Charged Property without notice and in such manner as may seem
advisable to the Receiver (including, without limitation, sale by way of
deferred payment arrangement), and to effect such sale by conveying in the name
and on behalf of the Obligor or otherwise.

 

Section 4.9                                   Dealings by Third Parties.

 

(1)                                  No Person dealing with the Collateral Agent, any of
the Secured Creditors or an agent or a Receiver is required to determine: (i) whether
the Charge has become enforceable; (ii) whether the powers which such
Person is purporting to exercise have become exercisable; (iii) whether
any money remains due to the Secured Creditors by the Obligor; (iv) the
necessity or expediency of the stipulations and conditions subject to which any
sale or lease shall be made; (v) the propriety or regularity of any sale
or any other dealing by the Collateral Agent or any Secured Creditor with the
Charged Property; or (vi) how any money paid to the Collateral Agent or
the Secured Creditors has been applied.

 

(2)                                  Any bona fide
purchaser of all or any part of the Charged Property from the Collateral Agent
or any Receiver or agent will hold the Charged Property absolutely, free from
any claim or right of whatever kind, including any equity of redemption, of the
Obligor, which it specifically waives (to the fullest extent permitted by law)
as against any such purchaser and all rights of redemption, stay or appraisal
which the Obligor has or may have under any rule of law now existing or
hereafter adopted.

 

Section 4.10                            No Right of Set-Off.

 

The principal, interest and other monies and
liabilities secured by this Debenture shall be paid when due by the Obligor
without regard to any equities existing between the

 

17

 

Obligor and any other party including, without
limitation, the Collateral Agent or any Secured Creditor and without regard to
any right of set-off or cross-claim or of any other claim or demand of the
Obligor against the Collateral Agent or any Secured Creditor.

Section 5.3                                   Discharge.

 

(1)                                  Except as otherwise expressly provided in Section 5.3(2) and
5.3(3), the Charge will be discharged upon, but only upon, full payment and
performance of the Secured Obligations and termination of all commitments
thereunder other than contingent indemnity obligations, if any.  Upon
discharge of the Charge and at the request and expense of the Obligor, the
Collateral Agent will execute and deliver to the Obligor such financing
statements and other documents or instruments as the Obligor may reasonably
require and the Collateral Agent will redeliver to the Obligor against receipt
and without recourse to or warranty by the Collateral Agent, or as the

 

19

 

Obligor may otherwise direct
the Collateral Agent, any Charged Property in its possession which shall not
have been sold or otherwise applied pursuant to the terms hereof.

 

(2)                                  The Charge in proceeds of Charged Property which:

 

(a)                                  constitute any Accounts (other than Accounts
comprising part of the Specified Contract Rights), Assigned Claims (other than
Assigned Claims comprising part of the Specified Contract Rights), cash, cash
equivalents, currency and moneys (other than cash, cash equivalents, currency
or moneys directed to be and deposited in or credited to the Collateral
Account) which arise, become payable or are paid or collected prior to the
Proceeds Date in the following circumstances:

 

(i)                                   where the ABL Credit Agent had no actual knowledge
that same constituted proceeds of Charged Property (x) at the time any
such Accounts or Assigned Claims giving rise to the payments, collections,
cash, cash equivalents, currency or moneys were created or, (y) in the
case of payments or collections, not resulting from any Account or Assigned
Claim, at the time such payments, collections, cash, cash equivalents, currency
or moneys were paid or collected; and

 

(ii)                                where at such Proceeds Date, there are outstanding
Loan Agreement Obligations; and

 

(iii)                             where the ABL Credit Agent in its sole discretion has
not expressly agreed that any such proceeds constitute proceeds of  Charged Property; and

 

(b)                                 which form part of the Liquidity Collateral;

 

will be automatically
released on the Proceeds Date without any further action by the Collateral
Agent.

 

For the purposes of this Section 5.3(2),
the terms “Accounts”, “Assigned Claims”, “Loan Agreement Obligations” and “Proceeds
Date” have the meaning ascribed thereto in the Intercreditor Agreement.

 

(3)                                  The Charged Property shall be released from the Charge
created hereunder pursuant to provisions of Section 8.04 and Section 8.07
of the Indenture; provided that after the issuance of Additional Secured
Obligations, no Charged Property shall be released from the Charge pursuant to
this Section 5.3(3), unless such release is also permitted by the
Additional Secured Debt Documents.

 

(4)                                  At any time that the Obligor desires that the
Collateral Agent take any action to acknowledge or give effect to any release
of Charged Property pursuant to Section 5.3(1), Section 5.3(2) or
Section 5.3(3) the Obligor shall deliver to the Collateral Agent (a) a
certificate signed by an officer of such Obligor stating that the release of
the

 

20

 

respective Charged Property

Additional Secured Creditor, to the provisions of the Additional Secured Debt

A reference herein to “$”, “U.S. $” or the word
“dollar” or “Dollars”, without more, shall be a reference to lawful money of
the United States of America.

 

Section 5.11                                        Severability.

 

If any court of competent jurisdiction from
which no appeal exists or is taken, determines any provision of this Debenture
to be illegal, invalid or unenforceable, that provision will be severed from
this Debenture and the remaining provisions will remain in full force and
effect.

 

Section 5.12                                        Amendment.

 

This Debenture may only be amended,
supplemented or otherwise modified by written agreement executed by the
Collateral Agent and the Obligor and subject to any consent of the Noteholders
required in accordance with the Indenture and any consent of the Additional

Section 5.13                                        Waivers, etc.

 

(1)                                  No consent or waiver by the Collateral Agent or the
Secured Creditors in respect of this Debenture is binding unless made in
writing and signed by an authorized officer of the Collateral Agent and subject

waiver of any other provision.

(2)                                  A failure or delay on the part of the Collateral Agent
or the Secured Creditors in exercising a right under this Debenture does not
operate as a waiver of, or impair, any right of the Collateral Agent or the
Secured Creditors however arising.  A
single or partial exercise of a right on the part of the Collateral Agent or
the Secured Creditors does not preclude any other or further exercise of that
right or the exercise of any other right by the Collateral Agent or the Secured
Creditors.

(4)                                  If, despite the provisions of this Debenture, any
Secured Creditor shall receive any payment or other recovery in excess of its
portion of payments on account of the Secured Obligations to which it is then
entitled in accordance with this Debenture, such Secured Creditor shall hold
such payment or recovery in trust for the benefit of all Secured Creditors for

Section 5.20                                        Additional Secured Obligations.

 

On or after the date hereof, the Issuers may
from time to time designate additional Obligations as additional Secured
Obligations hereunder (the “Additional
Secured Obligations”) by delivering to the Collateral Agent (a) a
certificate signed by the chief financial officer of the Issuers (i) identifying
the obligations so designated and the aggregate principal amount or face amount
thereof, stating that such obligations are designated as Additional Secured
Obligations for purposes hereof, (ii) representing that such designation
of such obligations as Additional Secured Obligations complies with the terms
of the Indenture and (iii) specifying the name and address of the
Authorized Representative for such obligations, and (b) a fully executed
Additional Secured Creditor Joinder (in the form attached as Schedule “B”).  Each Authorized Representative agrees that
upon the satisfaction of all conditions set forth in the preceding sentence,
the Collateral Agent shall act as agent under and subject to the terms of this
Debenture for the benefit of all Secured Creditors, including any Additional
Secured Creditors that hold any such Additional Secured Obligations, and each
Authorized Representative agrees to the appointment, and acceptance of the
appointment, of the Collateral Agent as agent for the holders of such
Additional Secured Obligations as set forth in the Additional Secured Creditor
Joinder, and the Authorized Representative providing such Additional Secured
Creditor Joinder shall, on behalf of itself and each Additional Secured
Creditor it represents, be bound by this Debenture.  For purposes of this Debenture, all
Obligations arising under or in connection with the Notes (including Additional
Notes and Exchange Notes) constitute Note Obligations rather than Additional
Secured Obligations; however upon the issuance of Additional Notes, the Issuers
shall deliver to the Collateral Agent a certificate signed by the chief
financial officer of the Issuers setting forth the particulars of the
Additional Notes

 

26

 

including
the aggregate principal amount or face amount thereof and certifying that such
issuance of First Lien Obligations complies with the terms of the Indenture.

 

Section 5.21                                        Collateral Agent.

 

(1)                                  Each
Noteholder, by its acceptance of the Indenture, and each—Authorized
Representative of any Additional Secured Creditors on behalf of itself and the
Additional Secured Creditors that it represents, by its execution of an
Additional Secured Creditor Joinder, has appointed, and each other Secured
Creditor, by accepting the benefits hereof, hereby appoints, BNY Trust Company
of Canada to serve as Collateral Agent and representative of itself and any
other Secured Creditors that it represents under each of the Security
Documents, and authorizes the Collateral Agent to act as agent for itself and
such Secured Creditors for the purpose of executing and delivering, on behalf
of itself and such Secured Creditors, each of the Security Documents and any
other documents or instruments related thereto or necessary or, as determined
by the Collateral Agent, desirable to perfect the Liens granted to the
Collateral Agent thereunder, for the purpose of holding the Liens on the
Collateral granted pursuant to the Security Documents, and, subject to the
provisions of this Debenture, for the purpose of enforcing its and such Secured
Creditors’ rights in respect of the Collateral and the obligations of the
Obligors under the Security Documents, and for the purpose of, or in connection
with, releasing the obligations of the Obligors under the Security
Documents.  The Collateral Agent hereby
agrees that it shall so act as Collateral Agent and representative of the
Secured Creditors subject to, in respect of any Additional Secured Creditors,
compliance by the Authorized Representative on behalf of such Additional
Secured Creditors with Section 5.20. The Collateral Agent shall have the
sole authority to exercise remedies under the Security Documents.  The Collateral Agent shall have the right
hereunder to make demands, to give notices, to exercise or refrain from
exercising any rights, and to take or refrain from taking action (including the
release or substitution of the Collateral), in accordance with the Secured
Agreements.  The Collateral Agent may resign, may be
removed and a successor Collateral Agent may be appointed in the manner
provided under Section 5.22.

 

(2)                                  The Collateral Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Charged Property in its
possession if such Charged Property is accorded treatment substantially
equivalent to that which a reasonable person accords his own property
consisting of similar property, instruments or interests, it being understood
that neither the Collateral Agent nor any of the Secured Creditors shall have
responsibility for taking any necessary steps to preserve rights against any
Person with respect to any Charged Property.

 

(3)                                  The Collateral Agent shall be entitled to rely upon
any written notice, statement, certificate, order or other document or any
telephone message believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person, and, with respect to all matters
pertaining to the Secured Agreements and its duties thereunder, upon advice of
counsel selected by it (who may be counsel to the Obligor).  The Collateral Agent shall not be deemed to
have actual, constructive,

 

27

 

direct or indirect knowledge
or notice of the occurrence of any Default or Event of Default unless and until
the Collateral Agent has received written notice from a Secured Creditor, the
Issuers or the Obligor referring to the applicable Secured Agreement,
describing such Default or Event of Default and stating that it is a “notice of
default” or a “notice of event of default”, setting forth in reasonable detail
the facts and circumstances thereof and stating that the Collateral Agent may
rely on such notice without further inquiry. 
The Collateral Agent shall have no obligation or duty prior to or after
receiving any such notice to inquire whether a Default or Event of Default has
in fact occurred and shall be entitled to conclusively rely, and shall be fully
protected in so relying, on any such notice furnished to it.

 

(4)                                  If any item of Charged Property also constitutes
collateral granted to the Collateral Agent under any other deed of trust,
mortgage, security agreement, pledge or instrument of any type, in the event of
any conflict between the provisions hereof and the provisions of such other
deed of trust, mortgage, security agreement, pledge or instrument of any type
in respect of such collateral, the terms of this Debenture shall apply.

 

(5)                                  Notwithstanding anything to the contrary contained
herein, the Collateral Agent is authorized, but not obligated, (i) to take
any action reasonably required to perfect or continue the perfection of the
liens on the Charged Property for the benefit of the Secured Creditors and (ii) when
instructions from the Authorized Representatives on behalf of the applicable
Secured Creditors have been requested by the Collateral Agent but have not yet
been received, to take any action which the Collateral Agent, in good faith,
believes to be reasonably required to promote and protect the interests of the
Secured Creditors in the Charged Property; provided that once instructions have
been received, the actions of the Collateral Agent shall be governed thereby
and the Collateral Agent shall not take any further action which would be
contrary thereto.

 

(6)                                  Notwithstanding
anything to the contrary contained herein or in any Security Document, the
Collateral Agent shall not be required to take or refrain from taking, and
shall have no liability to any Secured Creditor for taking or refraining from
taking, any action that exposes or, in the good faith judgment of the
Collateral Agent may expose, the Collateral Agent or its officers, directors,
agents or employees to personal liability, unless the Collateral Agent shall be
adequately indemnified, or that is, or in the good faith judgment of the
Collateral Agent may be, contrary to any Security Document, any other Secured
Agreement or applicable law.  Upon
receipt of such indemnity, however, the Collateral Agent shall act upon the
specific instructions of the Authorized Representatives provided in accordance
with the provisions of this Debenture, except for any instructions that in the
good faith judgment of the Collateral Agent may be contrary to any Security
Document, any other Secured Agreement or applicable law.

 

(7)                                  For purposes of
this Debenture and other Security Documents, each Secured Creditor shall
appoint a Person as its Authorized Representative for the purpose of giving or
delivering any notices or instructions hereunder and thereunder.  Any 

 

28

 

instructions given by the Authorized Representatives (other than the
Trustee) on behalf of the applicable Secured Creditors to the Collateral Agent
pursuant to the Security Documents shall be in writing signed by the Authorized
Representative(s) of the applicable Secured Creditors with respect to such
instructions and such instructions shall certify to and for the benefit of the
Collateral Agent the outstanding aggregate principal amount (or, in the case of
discount notes, accreted value) of all Secured Obligations that the Secured
Creditors authorizing such instructions hold. 
In determining whether the applicable Secured Creditors have consented
to any action under the Security Documents, the Collateral Agent may
conclusively rely on each Authorized Representative as to the amount of Secured
Obligations held by holders represented by such Authorized Representative.  The Collateral
Agent shall be entitled to conclusively and absolutely rely on such
instructions and certification as to the identity of the applicable Secured
Creditors with respect to such instructions, and the Collateral Agent shall not
be required to take any action, and shall not be liable to any Secured Creditor
for failing or refusing to act, pursuant to any instructions which are not
given or delivered by the Authorized Representatives of various Secured
Creditors comprising the applicable Secured Creditors as required by Section 3.11
of the Security Agreements.

 

(8)                                  The Obligor acknowledges that the rights and
responsibilities of the Collateral Agent under this Debenture with respect to
any action taken by the Collateral Agent or the exercise or nonexercise by the
Collateral Agent of any option, voting right, request, judgment or other right
or remedy provided for herein or resulting or arising out of this Debenture
shall, as between the Collateral Agent and the other Secured Creditors, be
governed by the provisions of this Debenture and by such other agreements with
respect thereto as may exist from time to time among them, but, as between the
Collateral Agent and the Obligor, the Collateral Agent shall be conclusively
presumed to be acting as agent for the Collateral Agent and the other Secured
Creditors with full and valid authority so to act or refrain from acting, and
the Obligor shall not be under any obligation, or entitlement, to make any
inquiry respecting such authority.

 

(9)                                  Subject to clause (6) of this Section 5.21,
neither the Collateral Agent nor any of its officers, directors, employees or
agents shall be liable for failure to demand, collect or realize upon any of
the Charged Property or for any delay in doing so or shall be under any
obligation to sell or otherwise dispose of any Charged Property upon the
request of the Obligor or any other Person or to take any other action
whatsoever with regard to the Charged Property or any part thereof.  The powers conferred on the Collateral Agent
hereunder are solely to protect the interests of the Collateral Agent in the
Charged Property and, subject to clause (6) of this Section 5.21,
shall not impose any duty upon the Collateral Agent to exercise any such
powers.  The Collateral Agent shall be
accountable only for amounts that it actually receives as a result of the
exercise of such powers, and neither it nor any of its officers, directors,
employees or agents shall have any duty or liability or be responsible to the
Obligor for any act or failure to act hereunder, except for its own gross
negligence or wilful misconduct.  The
Collateral Agent shall have no duty or liability as to the taking of any
necessary steps to preserve or protect the Charged Property or to preserve
rights

against prior parties.  Nothing contained in this Debenture shall be
construed as requiring or obligating the Collateral Agent, and the Collateral
Agent shall not be required or obligated, to (i) present or file any claim
or notice or take any action with respect to any Charged Property or in
connection therewith or (ii) notify the Obligor of any decline in the
value of any Charged Property.  The
Collateral Agent shall have no duty as to the collection of any Charged
Property in its possession or control or in the possession or control of any
agent or nominee of the Collateral Agent, or any income thereon or any other
rights pertaining thereto.

 

(10)                            No provision of the Secured Agreements shall be deemed
to impose any duty or obligation on the Collateral Agent to perform any act or
acts, receive or obtain any interest in property or exercise any interest in
property, or exercise any right, power, duty or obligation conferred or imposed
on it in any jurisdiction in which it shall be illegal, or in which the
Collateral Agent shall be unqualified or incompetent in accordance with
applicable law, to perform any such act or acts, to receive or obtain any such
interest in property or to exercise any such right, power, duty or obligation;
and no permissive or discretionary power or authority available to the
Collateral Agent shall be construed to be a duty.

 

(11)                            The Collateral Agent shall have the right hereunder to
make demands, to give notices, to exercise or refrain from exercising any
rights, and to take or refrain from taking action (including the release or
substitution of Charged Property), in each case in accordance with the Secured
Agreements.

 

(12)                            Upon resignation of the Collateral Agent in accordance
with the terms of Section 5.22, the Collateral Agent shall thereupon be
discharged from its duties and obligations under the Secured Agreements.  Following the resignation of the Collateral
Agent, the provisions of the Secured Agreements shall inure to its benefit as
to any actions taken or omitted to be taken by it under the Secured Agreements
while it was the Collateral Agent.

 

(13)                            The Collateral Agent shall not have any liability
hereunder except for its own gross negligence or wilful misconduct, or material
breach and under no circumstances shall the Collateral Agent be liable for any special,
punitive, exemplary or consequential damages.

 

(14)                            The Collateral
Agent shall be vested with all of the rights, powers, benefits, privileges and
protections of the Collateral Agent set forth in the Indenture, all of which
are incorporated herein and shall apply to all of the Security Documents.

 

(15)                            The Collateral
Agent may perform any and all of its duties and exercise its rights and powers
hereunder or under any other Indenture Document by or through, or delegate any
and all such rights and powers to, any one or more sub-agents appointed by such
Agent, including a sub-agent which is a non-U.S. affiliate of the Collateral
Agent. Except as otherwise provided in this Section 5.21, neither the
Collateral Agent nor any of its respective officers, directors, employees,
attorney or agents will be responsible or liable for the existence,
genuineness, value or protection of any Collateral, for the legality,
enforceability, effectiveness or sufficiency of the

 

30

 

Security
Documents, for the creation, perfection, priority, sufficiency or protection of
any Lien securing the First Lien Obligations, or for any defect or deficiency
as to any such matters, or for any failure to demand, collect, foreclose or
realize upon or otherwise enforce any such Liens or Security Documents or any
delay in doing so provided that if instructed by the Required Secured Creditors
in accordance with the provisions of the Security Documents, the Collateral
Agent (subject to receipt of an indemnity requested by it and acceptable to it
and any other applicable provisions of the Security Documents) shall comply
with instructions from such Required Secured Creditors.  The Collateral Agent and any such sub-agent
may perform any and all of its duties and exercise its rights and powers by or
through their respective Affiliates.  The exculpatory provisions of
this Section 5.21 shall apply to any agent, attorneys-in-fact or sub-agent
and to the Affiliates of the Collateral Agent and any such agent,
attorneys-in-fact or sub-agent, and shall apply to their respective activities
in connection with the exercise of the rights and remedies of the Collateral
Agent provided for hereunder, as well as all other activities as Collateral
Agent.

 

Section 5.22                                        Resignation and Removal of Collateral
Agent.

 

(1)                                  A resignation or removal of the Collateral Agent and
appointment of a successor Collateral Agent will become effective only upon the
successor Collateral Agent’s acceptance of appointment as provided in this Section 5.22.

 

(2)                                  The Collateral Agent may resign in writing at any time
and be discharged from its obligations hereunder created by so notifying the
Issuers.  Prior to the incurrence of
Additional Secured Obligations, the Holders of a majority in aggregate
principal amount of the then outstanding Notes may remove the Collateral Agent
by so notifying the Collateral Agent and the Issuers in writing.  After incurrence of the Additional Secured
Obligations, the Required Secured Creditors may remove the Collateral Agent by
so notifying the Collateral Agent and the Issuers in writing.  The Issuers may remove the Collateral Agent
if:

 

(a)                                  the Collateral Agent is adjudged a bankrupt or an
insolvent or an order for relief is entered with respect to the Collateral
Agent under any Bankruptcy Law;

 

(b)                                 a custodian or public officer takes charge of the
Collateral Agent or its property; or

 

(c)                                  the Collateral Agent becomes incapable of acting.

 

(3)                                  If the Collateral Agent resigns or is removed or if a
vacancy exists in the office of Collateral Agent for any reason, the Issuers
will promptly appoint a successor Collateral Agent.  Within one year after the successor
Collateral Agent takes office, the Holders of a majority in aggregate principal
amount of the then outstanding Notes (and, after the issuance of any Additional
Secured Obligations, solely the Required Secured Creditors) may appoint a
successor Collateral Agent to replace the successor Collateral Agent appointed
by the Issuers.

 

31

 

(4)                                  If a successor Collateral Agent does not take office
within sixty (60) days after the retiring Collateral Agent resigns or is
removed, the retiring Collateral Agent, the Issuers, or the Holders of at least
10% in aggregate principal amount of the then outstanding Notes (and, after the
issuance of any Additional Secured Obligations, the holders of at least 10% in
aggregate principal amount of the then outstanding Secured Obligations) may
petition any court of competent jurisdiction for the appointment of a successor
Collateral Agent.

 

(5)                                  A successor
Collateral Agent will deliver a written acceptance of its appointment to the
retiring Collateral Agent and to the Issuers. 
The resignation or removal of a Collateral Agent shall become effective
only upon (a) the execution and delivery of such documents or instruments
as are necessary to transfer the rights and obligations of the Collateral Agent
under the Security Documents and (b) the recording or filing of such
documents, instruments or financing statements and the delivery of such
Collateral as may be necessary to maintain the priority and perfection of any
security interest granted by the Security Documents.  Upon the acceptance of any appointment as the
Collateral Agent by a successor Collateral Agent and compliance with the
immediately preceding sentence, the resignation or removal of the retiring
Collateral Agent will become effective, and the successor Collateral Agent will
have all the rights, powers and duties of the Collateral Agent under the Indenture
and the Security Documents, and the retiring Collateral Agent shall thereupon
be discharged from its duties and obligations under the Secured
Agreements.  After any retiring
Collateral Agent’s resignation, the provisions hereof shall inure to its benefit
as to any actions taken or omitted to be taken by it under the Secured
Agreements while it was the Collateral Agent. 
The successor Collateral
Agent will mail a notice of its succession to each Authorized
Representative.  Notwithstanding
replacement of the Collateral Agent pursuant to this Section 5.22, the
Issuers’ obligations under Section 5.24 hereof will continue for the
benefit of the retiring Collateral Agent.

 

If the Collateral Agent consolidates, merges or
converts into, or transfers all or substantially all of its corporate trust
business to, another corporation, the successor corporation without any further
act will be the successor Collateral Agent.

 

Section 5.23                                        Assignment of Rents

 

As further security to the Collateral Agent for
the due payment and performance of all Secured Obligations, the Obligor, in its
own personal capacity and in its capacity as a partner (other than as a limited
partner), managing partner or general partner of any Partnership Obligor in
which it is a partner, managing partner or general partner, hereby assigns,
transfers and sets over to the Collateral Agent, for the benefit of the Secured
Creditors, to the extent not constituting Liquidity Collateral, all leases now
or hereafter granted by the Obligor (or any predecessor or successor in title)
of all or any part of the Charged Property and any rents and other revenues
from the Charged Property now or hereafter due or to become due, provided that:

 

(a)                                  the Collateral Agent will not be entitled to receive
and recover such rents and other revenues until an Event of Default has
occurred which is continuing;

 

32

 

(b)                                 the Collateral Agent will have no obligation to
collect any such rents or other revenues at any time and will be liable only
for monies actually received nor will the Collateral Agent be responsible for
the performance of any terms and conditions of any lease assigned hereunder;

 

(c)                                  nothing contained in this clause nor the exercise by
the Collateral Agent of any rights or remedies arising herefrom will place or
be deemed to place the Collateral Agent in possession of the Charged Property;

 

(d)                                 neither this assignment, nor the collection of rents
pursuant to it, will be construed as a recognition or acceptance of any lease
with respect to the Charged Property;

 

(e)                                  whenever requested by the Collateral Agent the Obligor
will assign to the Collateral Agent its interest in each specific lease of the
Charged Property and will execute such further specific or general assignments
as may be requested by the Collateral Agent from time to time;

 

(f)                                    the Collateral Agent or its agents may separately
register this assignment wherever the Collateral Agent in its discretion deems
appropriate; and

 

(g)                                 neither this assignment nor any act of the Collateral
Agent thereof shall operate to delay, hinder or prejudice any of the Collateral
Agent’s rights or remedies under this Debenture.

 

Section 5.24                                        Costs and Expenses.

 

(1)                                  The Obligor shall pay all reasonable out of pocket
expenses incurred by the Trustee or the Collateral Agent (including the fees,
charges and disbursements of not more than one counsel plus, if necessary, one
local counsel per jurisdiction for the Trustee or the Collateral Agent), in
connection with the enforcement or protection of its rights (i) in
connection with this Debenture and the other Indenture Documents including its
rights under this Section 5.24 (ii) in connection with the Indenture
Documents, the Charge created thereunder or the Charged Property, including all
legal fees, court costs, receiver’s or agent’s remuneration and other expenses
of taking possession of, repairing, protecting, insuring, preparing for
disposition, realizing, collecting, selling, transferring, delivering or
obtaining payment for the Charged Property, and of taking, defending or
participating in any action or proceeding in connection with any of the
foregoing matters or otherwise in connection with the interest of the
Collateral Agent, the Secured Creditors’ (or any one of them) interest in any
Charged Property, whether or not directly relating to the enforcement of this
Debenture and the other Indenture Documents, or (iii) in connection with
the issuance of Notes made under the Indenture, including all such
out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such issuance of Notes and (iv) all documentary
and similar taxes and charges in respect of the Indenture Documents.

 

33

 

(2)                                  The Obligor shall indemnify the Trustee (and any
sub-trustee thereof) and the Collateral Agent (and any sub-agent thereof), and
their respective Affiliates and each officer, director, employee or agent
thereof (each such person being called an “Indemnitee”)
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses (including reasonable fees, charges
and disbursements of any counsel for any Indemnitee) incurred by any Indemnitee
or asserted against any Indemnitee by any party hereto or any third party
arising out of, in connection with, or as a result of any action,
investigation, suit or proceeding (whether commenced or threatened) relating to
or arising out of (i) the execution or delivery of this Debenture, any
other Indenture  Document, or any
amendment, amendment and restatement, modification or waiver of the provisions
hereof or thereof, or any agreement or instrument contemplated hereby or
thereby, the performance by the parties hereto of their respective obligations
hereunder or thereunder or the consummation of the transactions contemplated
hereby or thereby, (ii) any issuance of Notes or the use or proposed use of the proceeds
therefrom, (iii) any actual or alleged presence or Release or threatened
Release of Hazardous Materials on, at, under or from any property or facility
owned, leased or operated by any Credit Party at any time, or any Environmental
Claim related in any way to any Credit Party, or (iv) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory, whether
brought by a third party or by the Issuer or any other Credit Party, and
regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses (x) are
determined by a court of competent jurisdiction to have resulted from the gross
negligence, bad faith or wilful misconduct of such Indemnitee or (y) result
from a claim brought by any Credit Party against an Indemnitee for breach in
bad faith of such Indemnitee’s obligations hereunder or under any other
Indenture Document, if such Credit Party has obtained a judgment in its favor
on such claim as determined by a court of competent jurisdiction.

 

(3)                                  All amounts due under this Section 5.24 shall be
payable not later than three (3) Business Days after demand therefor.

in the course of enforcement of the Charge.

instruments, contractual rights and governmental orders, authorizations,
licenses and permits now or hereafter pertaining thereto) to the same extent as
if this Debenture had not been executed; (ii) the exercise by or on behalf
of the Secured Creditors of any of their rights and remedies under or in regard
to this Debenture shall not release any Obligors from such duties and
obligations subject to applicable law; and (iii) the Secured Creditors (or
any of them) shall have no liability for such duties and obligations by reason

obligation, shall cover and secure any ultimate balance of the Secured  Obligations owing to the Secured Creditors, and shall be
operative and binding notwithstanding that at any time or times the Secured  Obligations may be zero, or that any payments from time to
time may be made to the Secured Creditors, or any settlements of account
effected, or any other thing whatsoever done, suffered or permitted, or any
other action short of complete and irrevocable payment of all the Secured  Obligations and any other amounts payable hereunder.

full power of substitution) to do, make and execute in the name of and on
behalf of such Obligor, upon (and only upon) the Charge becoming enforceable,
all such further acts, documents, matters and things which the Collateral Agent
may reasonably deem necessary or advisable to accomplish the purposes of this
Debenture for the recovery of all fees, tariffs and other sums of money that
may become or are now due or owing to such Obligor in respect of the Charged
Property and for the enforcement of all contracts, covenants or conditions
binding on any lessee or occupier of the Charged Property or on any Person in
respect of it, and this appointment shall take effect if the Charge has become
enforceable, subject to all applicable laws. 
The Collateral Agent or its nominees and transferees are empowered to
exercise all rights and powers and to perform all acts of ownership with
respect to the Charged Property and to deal with the Charged Property, to the
same extent as such Obligor might do. 
All acts of any such attorney are hereby ratified and approved, and the
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.

 

Section 4.6                                   Dealing with the Charged Property.

 

(1)                                  Except as otherwise provided by law or this Debenture, neither the
Collateral Agent, the Secured Creditors, any Receiver nor any agent of any of
them (including any civil enforcement agent) shall be: (i) liable or
accountable for any failure to collect, realize or obtain payment in respect of
the Charged Property; (ii) bound to institute proceedings for the purpose
of collecting, enforcing, realizing or obtaining payment of the Charged

other indulgences, take and give up securities, accept compositions, grant
releases and discharges and otherwise deal with any of the Obligors and with
other Persons,

securities as they may see fit without prejudice to the Secured  Obligations, the liability of any of the Obligors or the
rights of the Secured Creditors in respect of the Charged Property.

 

(3)                                  Neither the Collateral Agent nor the Secured Creditors shall be obliged
to exhaust their recourse against any of the Obligors or any other Person  or against any other security they may hold in respect of
the Secured  Obligations before realizing upon
or otherwise dealing with the Charged Property in such manner as the Collateral
Agent may consider desirable.

Agent is vested with the rights and remedies which could have been exercised by
the Collateral Agent in respect of any of the Obligors or the Charged Property
and such other powers and discretions as are granted in the instrument of
appointment and any supplemental instruments including, without limitation, any
or all of the powers of the Collateral Agent or of the officer of the

(2)                                  The Receiver shall, for all purposes relating to the Receiver’s acts or
defaults and remuneration, be deemed to be the agent of the Obligors and not of
the Collateral Agent or any of the Secured Creditors, and the Obligors shall be
solely responsible for the Receiver’s acts or defaults and remuneration.  The Receiver may sell, lease, or otherwise
dispose of Charged Property as agent for the Obligors or as agent for the
Collateral Agent or the Secured Creditors as the Collateral Agent may determine
in its discretion.

 

(3)                                  All amounts from time to time received by the Collateral Agent or the

discharge of all operating expenses and other outgoings affecting the Charged
Property; (ii) in keeping in good standing all Liens on the Charged
Property having priority over the Charge; (iii) in payment of the
remuneration and disbursements of the Receiver (if any); (iv) in payment
to the Collateral Agent of the amounts payable hereunder; (v) to such
reserves against potential claims that the Collateral Agent or the Receiver in
good faith believes should be maintained, until such potential claims are
settled, and the balance, if any, shall be paid in accordance with the
provisions of Section 5.14.

 

(4)                                  The Collateral Agent, in appointing or refraining from appointing any
Receiver, does not incur liability to the Receiver, any Obligors or otherwise
and is not responsible for any misconduct or negligence of such Receiver.

or otherwise, and to make any arrangement or compromise;

 

(b)                                 from time to time and without any previous notice or demand and free of
charge, enter upon or into and occupy and use all or any part of the premises,
buildings, plant and undertaking of or occupied or used by the Obligors without
being or being deemed to be a mortgagee in possession;

 

(c)                                  carry on or concur in carrying on all or any part of the business of any

priority to this Debenture or otherwise for such purposes as may be approved by
the Collateral Agent; and

 

(e)                                  sell or lease or concur in selling or leasing all or any part of the
Charged Property without notice and in such manner as may seem advisable to the
Receiver (including, without limitation, sale by way of deferred payment
arrangement), and to effect such sale by conveying in the name and on behalf of
the applicable Obligor or otherwise.

 

Section 4.9                                   Dealings by Third Parties.

 

(1)                                  No Person dealing with the Collateral Agent, any of the Secured
Creditors or an agent or a Receiver is required to determine: (i) whether
the Charge has become enforceable; (ii) whether the powers which such
Person is purporting to exercise have become exercisable; (iii) whether
any money remains due to the Secured Creditors by any Obligor; (iv) the
necessity or expediency of the stipulations and conditions subject to which any
sale or lease shall be made; (v) the propriety or regularity of any sale
or any other dealing by the Collateral Agent or any Secured Creditor with the
Charged Property; or (vi) how any money paid to the Collateral Agent or
the Secured Creditors has been applied.

 

(2)                                  Any bona fide purchaser of all or any part
of the Charged Property from the Collateral Agent or any Receiver or agent will
hold the Charged Property absolutely, free from any claim or right of whatever
kind, including any equity of redemption, of any Obligor, which it specifically
waives (to the fullest extent permitted by law) as against any such purchaser
and all rights of redemption, stay or appraisal which any Obligor has or may
have under any rule of law now existing or hereafter adopted.

 

Section 4.10                            No Right of Set-Off.

 

The principal, interest and other monies and
liabilities secured by this Debenture shall be paid when due by any of the
Obligors without regard to any equities existing between the Obligors and any
other party including, without limitation, the Collateral Agent or any Secured
Creditor and without regard to any right of set-off or cross-claim or of any
other claim or demand of the Obligors against the Collateral Agent or any
Secured Creditor.

Section 5.3                                   Discharge.

 

(1)                                  Except as otherwise expressly provided in Section 5.3(2) and
5.3(3), the Charge will be discharged upon, but only upon, full payment and
performance of the Secured Obligations and termination of all commitments
thereunder other than contingent indemnity obligations, if any.  Upon
discharge of the Charge and at the request and expense of the Obligors, the
Collateral Agent will execute and deliver to the Obligors such financing
statements and other documents or instruments as the Obligors may reasonably
require and the Collateral Agent will redeliver to the Obligors against receipt
and without recourse to or warranty by the Collateral Agent, or as the Obligors
may otherwise direct the Collateral Agent, any Charged Property in its
possession which shall not have been sold or otherwise applied pursuant to the
terms hereof.

 

(2)                                  The Charge in proceeds of Charged Property which:

 

(a)                                  constitute any Accounts (other than Accounts comprising part of the
Specified Contract Rights), Assigned Claims (other than Assigned Claims
comprising part of the Specified Contract Rights), cash, cash equivalents,
currency and moneys (other than cash, cash equivalents, currency or moneys
directed to be and deposited in or credited to the Collateral Account) which
arise, become payable or are paid or collected prior to the Proceeds Date in
the following circumstances:

 

(i)                                     where the ABL Credit Agent had no actual knowledge that same constituted
proceeds of Charged Property (x) at the time any such Accounts or Assigned
Claims giving rise to the payments, collections, cash, cash equivalents,
currency or moneys were created or, (y) in the case of payments or
collections, not resulting from any Account or Assigned Claim, at the time such
payments, collections, cash, cash equivalents, currency or moneys were paid or
collected; and

 

(ii)                                  where at such Proceeds Date, there are outstanding Loan Agreement
Obligations; and

 

(iii)                               where the ABL Credit Agent in its sole discretion has not expressly
agreed that any such proceeds constitute proceeds of Charged Property; and

 

(b)                                 which form part of the Liquidity Collateral;

 

will be automatically
released on the Proceeds Date without any further action by the Collateral
Agent.

 

19

 

For the purposes of
this Section 5.3(2) the terms “Accounts”, “Assigned Claims”, “Loan
Agreement Obligations” and “Proceeds Date” have the meaning ascribed thereto in
the Intercreditor Agreement.

 

(3)                                  The Charged Property shall be released from the
Charge created hereunder pursuant to provisions of Section 8.04 and Section 8.07
of the Indenture; provided that after the issuance of Additional Secured
Obligations, no Charged Property shall be released from the Charge pursuant to
this Section 5.2(3), unless such release is also permitted by the
Additional Secured Debt Documents.

 

(4)                                  At any time that any Obligor desires that the
Collateral Agent take any action to acknowledge or give effect to any release
of Charged Property pursuant to Section 5.3(1), Section 5.3(2) or
Section 5.3(3) the Obligor shall deliver to the Collateral Agent (a) a
certificate signed by an officer of such Obligor stating that the release of
the respective Charged Property is permitted pursuant to such Section 5.3(1),
Section 5.3(2) or Section 5.3(3) and (b) any other
documents required by Section 8.04 of the Indenture.

 

(5)                                  The Collateral Agent shall have no liability whatsoever to any other
Secured Creditor as the result of any release of Charged Property by it in
accordance with (or which the Collateral Agent believes to be in accordance
with) this Section 5.3.

 

Section 5.4                                   No Merger.

 

This Debenture shall not operate by way of
merger of any of the Secured  Obligations
and no judgment recovered by the Collateral Agent or any of the Secured
Creditors shall operate by way of merger of, or in any way affect, the Charge,
which is in addition to, and not in substitution for, any other security held
by the Collateral Agent and the Secured Creditors in respect of the Secured  Obligations. The representations, warranties and covenants
of each of the Obligors in this Debenture survive the execution and delivery of
this Debenture and the issuance of Notes.  Notwithstanding any investigation made by or
on behalf of the Collateral Agent or the Secured Creditors these covenants,
representations and warranties continue in full force and effect.

 

Section 5.5                                   Undertaking to Provide Fixed Charge.

 

If an Event of
Default has occurred and is at the time of the determination by the Collateral
Agent pursuant to this Section 5.5 continuing and the Collateral Agent
considers it necessary for adequate protection of the Secured Creditors, each
of the Obligors, at the request of the Collateral Agent, will forthwith grant
or cause to be granted to the Collateral Agent for and on behalf of itself and
the Secured Creditors a fixed charge and Lien in such of the Obligors’ real
property, as the Collateral Agent will, in its sole discretion, determine as
security for all then present and future indebtedness of any Obligor to the
Collateral Agent or the Secured Creditors in connection with this
Debenture.  In this regard, each of the
Obligors will:

 

(a)                                  provide the Collateral Agent with such information as is reasonably
required by it to identify the property to be so charged;

 

20

 

(b)                                 do all such things as are reasonably required to grant in favour of the
Collateral Agent for and on behalf of itself and the Secured Creditors a fixed
charge and Lien in respect of such property to be so charged;

 

(c)                                  provide the Collateral Agent with all corporate resolutions and other
action, as reasonably required for such Obligor, to grant to the Collateral
Agent for and on behalf of itself and the Secured Creditors a fixed charge and
Lien in its property identified by the Collateral Agent to be so charged;

 

(d)                                 provide the Collateral Agent with such security instruments and other
documents which the Collateral Agent, acting reasonably, deems are necessary to
give full force and effect to the provisions of this Section;

 

(e)                                  assist the Collateral Agent in the registration or recording of such
agreements and instruments in such public registry offices as the Collateral
Agent, acting reasonably, deems necessary to give full force and effect to these
provisions; and

 

(f)                                    pay all reasonable costs and expenses incurred by the Collateral Agent
in connection with the preparation, execution and registration of all
agreements, documents and instruments, including any amendments to the
Indenture Documents, made in connection herewith.

things and execute and deliver, or cause to be executed and delivered, all
agreements, documents and instruments that the Collateral Agent may require and
take all further steps relating to the Charged Property or any other property
or assets of such Obligor that the Collateral Agent may require for: (i) protecting
the Charged Property; (ii) perfecting, preserving or protecting the
Charge; and (iii) exercising all powers, authorities and discretions
hereby conferred upon the Collateral Agent. 
After the Charge becomes enforceable, each of the Obligors will do all
acts and things and execute and deliver all documents and instruments as the
Collateral Agent may require for facilitating the sale or other disposition of
the Charged Property in connection with its realization.

respect hereto.  Without 

 

21

 

limiting

thereof granted to such Secured Creditor, herein or otherwise, subject however,
in the case of a Noteholder, to the provisions of the Indenture, and in the
case of an Additional Secured Creditor, to the provisions of the Additional
Secured Debt Documents.  None of the Obligors may assign,
transfer or delegate any of its rights or obligations under this Debenture
without the prior written consent of the Collateral Agent which may be
unreasonably withheld except pursuant to
transactions permitted under the Indenture.  Each of the Obligors agrees that its
obligations hereunder and the Charge shall continue to be effective or be
reinstated, as applicable, if at any time payment, or any part thereof, of all
or any part of the Secured Obligations is rescinded or must otherwise be
restored by the Secured Creditors upon the bankruptcy or reorganization of any
Obligor or otherwise.

Each of the Obligors acknowledges and agrees
that in the event it amalgamates with any other corporation or corporations, it
is the intention of the parties that the Charge (i) subject to Section 3.5,
extends to: (A) all of the property of the type and description set forth

of the property of the type and description set forth in Section 3.1 that

the payment and performance of all debts, liabilities and obligations of each
of the amalgamating corporations and the amalgamated corporation of type and description
set forth in Section 3.2 and whether incurred prior to, at the time of or
subsequent to the amalgamation.   The
Charge attaches to the additional collateral at the time of amalgamation and to
any collateral thereafter owned or acquired by the amalgamated corporation when
such becomes owned or is acquired.  Upon
any such amalgamation, the defined term “Obligor” includes, collectively,
each of the amalgamating corporations and the amalgamated corporation, the
defined term “Charged
Property” means all of the property and undertaking and interests
described in (i) above, and the defined term “Secured Obligations” means the
obligations described in (ii) above.

Section 5.11                            Severability.

 

If any court of competent jurisdiction from
which no appeal exists or is taken, determines any provision of this Debenture
to be illegal, invalid or unenforceable, that provision will be severed from
this Debenture and the remaining provisions will remain in full force and
effect.

 

22

 

Section 5.12                            Amendment.

 

This Debenture may only be amended,
supplemented or otherwise modified by written agreement executed by the
Collateral Agent and each of the Obligors affected by such amendment,
supplement or modification and subject to any consent of the Noteholders
required in accordance with the Indenture and any consent of the Additional
Secured Creditors required by the Additional Secured Debt Documents.

 

Section 5.13                            Waivers, etc.

Secured Creditors in respect of this Debenture is binding unless made in

to any consent of the Noteholders required in accordance with the Indenture and
any consent of the Additional Secured Creditors required by the Additional
Secured Debt Documents.  Any consent or
waiver given under this Debenture is effective only in the specific instance
and for the specific purpose for which given. 
No waiver of any of the provisions of this Debenture constitutes a
waiver of any other provision.

 

(2)                                  A failure or delay on the part of the Collateral Agent or the Secured
Creditors in exercising a right under this Debenture does not operate as a
waiver of, or impair, any right of the Collateral Agent or the Secured
Creditors however arising.  A single or
partial exercise of a right on the part of the Collateral Agent or the Secured
Creditors does not preclude any other or further exercise of that right or the
exercise of any other right by the Collateral Agent or the Secured Creditors.

 

Section 5.14                            Application of Proceeds of Security.

(c)                                  Third, without duplication of amounts applied pursuant to clause (1) above,

(e)                                  Fifth, the balance, if any, to the Person lawfully entitled thereto
(including the applicable Credit Party or its successors or assigns) or as a
court of competent jurisdiction may direct.

 

All applications of proceeds pursuant to
clauses (a) though (d) above shall be allocated among the Secured
Creditors on a pro
rata basis according to the principal

owing in respect of the Secured Obligations at the time of the
distribution.  In the event that any such
proceeds are insufficient to pay in full the items described in clauses (1) through

severally, liable for any deficiency.

 

(3)                                  Upon the request of the Collateral Agent prior to any distribution under
this Section 5.14, each Secured Creditor or its Authorized Representative
shall provide to the Collateral Agent certificates, in form and substance
reasonably satisfactory to the Collateral Agent, setting forth the respective

Authorized Representative believes it is entitled to receive, and the
Collateral Agent shall be fully entitled to rely on such certificates.

 

(4)                                  If, despite the provisions of this Debenture, any Secured Creditor shall
receive any payment or other recovery in excess of its portion of payments on
account of the Secured Obligations to which it is then entitled in accordance
with this Debenture, such Secured Creditor shall hold such payment or recovery
in trust for the benefit of all Secured Creditors for distribution in accordance
with this Section 5.14.

Section 5.22                            Additional Secured Obligations.

 

On or after the date hereof,
the Issuers may from time to time designate additional Obligations as
additional Secured Obligations hereunder (the “Additional
Secured Obligations”) by
delivering to the Collateral Agent (a) a certificate signed by the chief
financial officer of the Issuers (i) identifying the obligations so
designated and the aggregate principal amount or face amount thereof, stating
that such obligations are designated as Additional Secured Obligations for
purposes hereof, (ii) representing that such designation of such
obligations as Additional Secured Obligations complies with the terms of the
Indenture and (iii) specifying the name and address of the Authorized
Representative for such obligations, and (b) a fully executed Additional
Secured Creditor Joinder (in the form attached as Schedule “B”).  Each Authorized Representative agrees that
upon the satisfaction of all conditions set forth in the preceding sentence,
the Collateral Agent shall act as agent under and subject to the terms of this
Debenture for the benefit of all Secured Creditors, including any Additional
Secured Creditors that hold any such Additional Secured Obligations, and each
Authorized Representative agrees to the appointment, and acceptance of the
appointment, of the Collateral Agent as agent for the holders of such
Additional Secured Obligations as set forth in the Additional Secured Creditor
Joinder,
and the Authorized Representative providing such Additional Secured Creditor
Joinder shall, on behalf of itself and each Additional Secured Creditor it
represents, be bound by this 

 

26

 

Debenture.  For
purposes of this Debenture, all Obligations arising under or in connection with
the Notes (including Additional Notes and Exchange Notes) constitute Note
Obligations rather than Additional Secured Obligations; however upon the
issuance of Additional Notes, the Issuers shall deliver to the Collateral Agent
a certificate signed by the chief financial officer of the Issuers setting
forth the particulars of the Additional Notes including the aggregate principal
amount or face amount thereof and certifying that such issuance of First Lien
Obligations complies with the terms of the Indenture.

 

Section 5.23                            Collateral Agent.

 

(1)                                  Each Noteholder, by its acceptance
of the Indenture, and each Authorized Representative of any Additional Secured
Creditors on behalf of itself and the Additional Secured Creditors that it
represents, by its execution of an Additional Secured Creditor Joinder, has
appointed, and each other Secured Creditor, by accepting the benefits hereof,
hereby appoints, BNY Trust Company of Canada to serve as Collateral Agent and
representative of itself and any other Secured Creditors that it represents
under each of the Security Documents, and authorizes the Collateral Agent to
act as agent for itself and such Secured Creditors for the purpose of executing
and delivering, on behalf of itself and such Secured Creditors, each of the
Security Documents and any other documents or instruments related thereto or
necessary or, as determined by the Collateral Agent, desirable to perfect the
Liens granted to the Collateral Agent thereunder, for the purpose of holding
the Liens on the Collateral granted pursuant to the Security Documents, and,
subject to the provisions of this Debenture, for the purpose of enforcing its
and such Secured Creditors’ rights in respect of the Collateral and the
obligations of the Obligors under the Security Documents, and for the purpose
of, or in connection with, releasing the obligations of the Obligors under the
Security Documents.  The Collateral Agent
hereby agrees that it shall so act as Collateral Agent and representative of
the Secured Creditors subject to, in respect of any Additional Secured
Creditors, compliance by the Authorized Representative on behalf of such
Additional Secured Creditors with Section 5.22. The Collateral Agent shall
have the sole authority to exercise remedies under the Security Documents.  The Collateral Agent shall have the right
hereunder to make demands, to give notices, to exercise or refrain from
exercising any rights, and to take or refrain from taking action (including the
release or substitution of the Collateral), in accordance with the Secured
Agreements.  The
Collateral Agent may resign, may be removed and a successor Collateral Agent
may be appointed in the manner provided under Section 5.24.

 

(2)                                  The Collateral Agent shall be deemed to have exercised reasonable care
in the custody and preservation of the Charged Property in its possession if
such Charged Property is accorded treatment substantially equivalent to that
which a reasonable person accords his own property consisting of similar
property, instruments or interests, it being understood that neither the
Collateral Agent nor any of the Secured Creditors shall have responsibility for
taking any necessary steps to preserve rights against any Person with respect
to any Charged Property.

 

27

 

(3)                                  The Collateral Agent shall be entitled to rely upon any written notice,
statement, certificate, order or other document or any telephone message
believed by it to be genuine and correct and to have been signed, sent or made
by the proper Person, and, with respect to all matters pertaining to the Secured
Agreements and its duties thereunder, upon advice of counsel selected by it
(who may be counsel to one or more of the Obligors).  The Collateral Agent shall not be deemed to
have actual, constructive, direct or indirect knowledge or notice of the occurrence
of any Default or Event of Default unless and until the Collateral Agent has
received written notice from a Secured Creditor, the Issuers or an Obligor
referring to the applicable Secured Agreement, describing such Default or Event
of Default and stating that it is a “notice of default” or a “notice of event
of default”, setting forth in reasonable detail the facts and circumstances
thereof and stating that the Collateral Agent may rely on such notice without
further inquiry.  The Collateral Agent shall
have no obligation or duty prior to or after receiving any such notice to
inquire whether a Default or Event of Default has in fact occurred and shall be
entitled to conclusively rely, and shall be fully protected in so relying, on
any such notice furnished to it.

 

(4)                                  If any item of Charged Property also constitutes collateral granted to
the Collateral Agent under any other deed of trust, mortgage, security
agreement, pledge or instrument of any type, in the event of any conflict
between the provisions hereof and the provisions of such other deed of trust,
mortgage, security agreement, pledge or instrument of any type in respect of
such collateral, the terms of this Debenture shall apply.

 

(5)                                  Notwithstanding anything to the contrary contained herein, the
Collateral Agent is authorized, but not obligated, (i) to take any action
reasonably required to perfect or continue the perfection of the liens on the
Charged Property for the benefit of the Secured Creditors and (ii) when
instructions from the Authorized Representatives on behalf of the applicable
Secured Creditors have been requested by the Collateral Agent but have not yet
been received, to take any action which the Collateral Agent, in good faith,
believes to be reasonably required to promote and protect the interests of the
Secured Creditors in the Charged Property; provided that once instructions have
been received, the actions of the Collateral Agent shall be governed thereby
and the Collateral Agent shall not take any further action which would be
contrary thereto.

 

(6)                                  Notwithstanding anything to the
contrary contained herein or in any Security Document, the Collateral Agent
shall not be required to take or refrain from taking, and shall have no
liability to any Secured Creditor for taking or refraining from taking, any
action that exposes or, in the good faith judgment of the Collateral Agent may
expose, the Collateral Agent or its officers, directors, agents or employees to
personal liability, unless the Collateral Agent shall be adequately indemnified,
or that is, or in the good faith judgment of the Collateral Agent may be,
contrary to any Security Document, any other Secured Agreement or applicable
law.  Upon receipt of such indemnity,
however, the Collateral Agent shall act upon the specific instructions of the
Authorized Representatives provided in accordance with the provisions of this
Debenture, except for any instructions that in the good faith 

 

28

 

judgment
of the Collateral Agent may be contrary to any Security Document, any other
Secured Agreement or applicable law.

 

(7)                                  For purposes of this Debenture and
other Security Documents, each Secured Creditor shall appoint a Person as its
Authorized Representative for the purpose of giving or delivering any notices
or instructions hereunder and thereunder. 
Any instructions given by the Authorized Representatives (other than the
Trustee) on behalf of the applicable Secured Creditors to the Collateral Agent pursuant
to the Security Documents shall be in writing signed by the Authorized
Representative(s) of the applicable Secured Creditors with respect to such
instructions and such instructions shall certify to and for the benefit of the
Collateral Agent the outstanding aggregate principal amount (or, in the case of
discount notes, accreted value) of all Secured Obligations that the Secured
Creditors authorizing such instructions hold. 
In determining whether the applicable Secured Creditors have consented
to any action under the Security Documents, the Collateral Agent may
conclusively rely on each Authorized Representative as to the amount of Secured
Obligations held by holders represented by such Authorized Representative.    The Collateral Agent shall be entitled to
conclusively and absolutely rely on such instructions and certification as to
the identity of the applicable Secured Creditors with respect to such
instructions, and the Collateral Agent shall not be required to take any
action, and shall not be liable to any Secured Creditor for failing or refusing
to act, pursuant to any instructions which are not given or delivered by the
Authorized Representatives of various Secured Creditors comprising the
applicable Secured Creditors as required by Section 3.11 of the Security
Agreements.

 

(8)                                  Each Obligor acknowledges that the rights and responsibilities of the
Collateral Agent under this Debenture with respect to any action taken by the
Collateral Agent or the exercise or nonexercise by the Collateral Agent of any
option, voting right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Debenture shall, as between the
Collateral Agent and the other Secured Creditors, be governed by the provisions
of this Debenture and by such other agreements with respect thereto as may
exist from time to time among them, but, as between the Collateral Agent and
the Obligors, the Collateral Agent shall be conclusively presumed to be acting
as agent for the Collateral Agent and the other Secured Creditors with full and
valid authority so to act or refrain from acting, and no Obligor shall be under
any obligation, or entitlement, to make any inquiry respecting such authority.

 

(9)                                  Subject to clause (6) of this Section 5.23, neither the
Collateral Agent nor any of its officers, directors, employees or agents shall
be liable for failure to demand, collect or realize upon any of the Charged
Property or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Charged Property upon the request of any Obligor or
any other Person or to take any other action whatsoever with regard to the
Charged Property or any part thereof. 
The powers conferred on the Collateral Agent hereunder are solely to
protect the interests of the Collateral Agent in the Charged Property and,
subject to clause (6) of this Section 5.23, shall not impose any duty
upon the Collateral Agent to exercise any such powers.  The

 

29

 

Collateral Agent
shall be accountable only for amounts that it actually receives as a result of
the exercise of such powers, and neither it nor any of its officers, directors,
employees or agents shall have any duty or liability or be responsible to any Obligor
for any act or failure to act hereunder, except for its own gross negligence or
wilful misconduct.  The Collateral Agent
shall have no duty or liability as to the taking of any necessary steps to
preserve or protect the Charged Property or to preserve rights against prior
parties.  Nothing contained in this
Debenture shall be construed as requiring or obligating the Collateral Agent,
and the Collateral Agent shall not be required or obligated, to (i) present
or file any claim or notice or take any action with respect to any Charged
Property or in connection therewith or (ii) notify any Obligor of any
decline in the value of any Charged Property. 
The Collateral Agent shall have no duty as to the collection of any
Charged Property in its possession or control or in the possession or control
of any agent or nominee of the Collateral Agent, or any income thereon or any
other rights pertaining thereto.

 

(10)                            No provision of the Secured Agreements shall be deemed to impose any
duty or obligation on the Collateral Agent to perform any act or acts, receive
or obtain any interest in property or exercise any interest in property, or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Collateral Agent
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts, to receive or obtain any such interest in
property or to exercise any such right, power, duty or obligation; and no
permissive or discretionary power or authority available to the Collateral
Agent shall be construed to be a duty.

 

(11)                            The Collateral Agent shall have the right hereunder to make demands, to
give notices, to exercise or refrain from exercising any rights, and to take or
refrain from taking action (including the release or substitution of Charged
Property), in each case in accordance with the Secured Agreements.

 

(12)                            Upon resignation of the Collateral Agent in accordance with the terms of
Section 5.24, the Collateral Agent shall thereupon be discharged from its
duties and obligations under the Secured Agreements.  Following the resignation of the Collateral
Agent, the provisions of the Secured Agreements shall inure to its benefit as
to any actions taken or omitted to be taken by it under the Secured Agreements
while it was the Collateral Agent.

 

(13)                            The Collateral Agent shall not have any liability hereunder except for
its own gross negligence or wilful misconduct, or material breach and under no
circumstances shall the Collateral Agent be liable for any special, punitive,
exemplary or consequential damages.

 

(14)                            The Collateral Agent shall be
vested with all of the rights, powers, benefits, privileges and protections of
the Collateral Agent set forth in the Indenture, all of which are incorporated
herein and shall apply to all of the Security Documents.

 

(15)                            The Collateral Agent may perform
any and all of its duties and exercise its rights and powers hereunder or under
any other Indenture Document by or through, or 

 

30

 

delegate
any and all such rights and powers to, any one or more sub-agents appointed by
such Agent, including a sub-agent which is a non-U.S. affiliate of the
Collateral Agent. Except as otherwise provided in this Section 5.23,
neither the Collateral Agent nor any of its respective officers, directors,
employees, attorney or agents will be responsible or liable for the existence,
genuineness, value or protection of any Collateral, for the legality, enforceability,
effectiveness or sufficiency of the Security Documents, for the creation,
perfection, priority, sufficiency or protection of any Lien securing the First
Lien Obligations, or for any defect or deficiency as to any such matters, or
for any failure to demand, collect, foreclose or realize upon or otherwise
enforce any such Liens or Security Documents or any delay in doing so provided
that if instructed by the Required Secured Creditors in accordance with the
provisions of the Security Documents, the Collateral Agent (subject to receipt
of an indemnity requested by it and acceptable to it and any other applicable
provisions of the Security Documents) shall comply with instructions from such
Required Secured Creditors.  The
Collateral Agent and any such sub-agent may perform any and all of its duties
and exercise its rights and powers by or through their respective Affiliates.  The
exculpatory provisions of this Section 5.23 shall apply to any agent,
attorneys-in-fact or sub-agent and to the Affiliates of the Collateral Agent
and any such agent, attorneys-in-fact or sub-agent, and shall apply to their
respective activities in connection with the exercise of the rights and
remedies of the Collateral Agent provided for hereunder, as well as all other activities
as Collateral Agent.

 

Section 5.24                                        Resignation and Removal of Collateral Agent.

 

(1)                                  A resignation or removal of the Collateral Agent
and appointment of a successor Collateral Agent will become effective only upon
the successor Collateral Agent’s acceptance of appointment as provided in this Section 5.24.

 

(2)                                  The Collateral Agent may resign in writing at any
time and be discharged from its obligations hereunder created by so notifying
the Issuers.  Prior to the incurrence of
Additional Secured Obligations, the Holders of a majority in aggregate
principal amount of the then outstanding Notes may remove the Collateral Agent
by so notifying the Collateral Agent and the Issuers in writing.  After incurrence of the Additional Secured
Obligations, the Required Secured Creditors may remove the Collateral Agent by
so notifying the Collateral Agent and the Issuers in writing.  The Issuers may remove the Collateral Agent
if:

 

(a)                                  the Collateral Agent is adjudged a bankrupt or an
insolvent or an order for relief is entered with respect to the Collateral
Agent under any Bankruptcy Law;

 

(b)                                 a custodian or public officer takes charge of the
Collateral Agent or its property; or

 

(c)                                  the Collateral Agent becomes incapable of acting.

 

(3)                                  If the Collateral Agent resigns or is removed or if
a vacancy exists in the office of Collateral Agent for any reason, the Issuers
will promptly appoint a successor 

 

31

 

Collateral Agent.  Within one year after the successor Collateral
Agent takes office, the Holders of a majority in aggregate principal amount of
the then outstanding Notes (and, after the issuance of any Additional Secured
Obligations, solely the Required Secured Creditors) may appoint a successor
Collateral Agent to replace the successor Collateral Agent appointed by the
Issuers.

 

(4)                                  If a successor Collateral Agent does not take
office within sixty (60) days after the retiring Collateral Agent resigns or is
removed, the retiring Collateral Agent, the Issuers, or the Holders of at least
10% in aggregate principal amount of the then outstanding Notes (and, after the
issuance of any Additional Secured Obligations, the holders of at least 10% in
aggregate principal amount of the then outstanding Secured Obligations) may petition
any court of competent jurisdiction for the appointment of a successor
Collateral Agent.

 

(5)                                  A successor Collateral Agent will
deliver a written acceptance of its appointment to the retiring Collateral
Agent and to the Issuers.  The
resignation or removal of a Collateral Agent shall become effective only upon (a) the
execution and delivery of such documents or instruments as are necessary to
transfer the rights and obligations of the Collateral Agent under the Security
Documents and (b) the recording or filing of such documents, instruments
or financing statements and the delivery of such Collateral as may be necessary
to maintain the priority and perfection of any security interest granted by the
Security Documents.    Upon the
acceptance of any appointment as the Collateral Agent by a successor Collateral
Agent and compliance with the immediately preceding sentence, the resignation
or removal of the retiring Collateral Agent will become effective, and the
successor Collateral Agent will have all the rights, powers and duties of the
Collateral Agent under the Indenture and the Security Documents, and the
retiring Collateral Agent shall thereupon be discharged from its duties and
obligations under the Secured Agreements. 
After any retiring Collateral Agent’s resignation, the provisions hereof
shall inure to its benefit as to any actions taken or omitted to be taken by it
under the Secured Agreements while it was the Collateral Agent.  The
successor Collateral Agent will mail a notice of its succession to each
Authorized Representative. 
Notwithstanding replacement of the Collateral Agent pursuant to this Section 5.24,
the Issuers’ obligations under Section 5.26 hereof will continue for the
benefit of the retiring Collateral Agent.

 

If the Collateral Agent
consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, the successor corporation
without any further act will be the successor Collateral Agent.

 

Section 5.25                                        Assignment of Rents

 

As further security to the Collateral Agent for
the due payment and performance of all Secured Obligations, each of the
Obligors, in its own personal capacity and in its capacity as a partner (other
than as a limited partner), managing partner or general partner of any
Partnership Obligor in which it is a partner, managing partner or general
partner, hereby assigns, transfers and sets over to the Collateral Agent, for
the benefit of the Secured Creditors, to the extent not constituting Liquidity
Collateral, all leases now or hereafter 

 

32

 

granted by each such
Obligor (or any predecessor or successor in title) of all or any part of the
Charged Property and any rents and other revenues from the Charged Property now
or hereafter due or to become due, provided that:

 

(a)                                  the Collateral Agent will not be entitled to receive and recover such
rents and other revenues until an Event of Default has occurred which is
continuing;

 

(b)                                 the Collateral Agent will have no obligation to collect any such rents
or other revenues at any time and will be liable only for monies actually
received nor will the Collateral Agent be responsible for the performance of
any terms and conditions of any lease assigned hereunder;

 

(c)                                  nothing contained in this clause nor the exercise by the Collateral
Agent of any rights or remedies arising herefrom will place or be deemed to
place the Collateral Agent in possession of the Charged Property;

 

(d)                                 neither this assignment, nor the collection of rents pursuant to it,
will be construed as a recognition or acceptance of any lease with respect to
the Charged Property;

 

(e)                                  whenever requested by the Collateral Agent such Obligor will assign to
the Collateral Agent its interest in each specific lease of the Charged
Property and will execute such further specific or general assignments as may
be requested by the Collateral Agent from time to time;

 

(f)                                    the Collateral Agent or its agents may separately register this
assignment wherever the Collateral Agent in its discretion deems appropriate;
and

 

(g)                                 neither this assignment nor any act of the Collateral Agent thereof
shall operate to delay, hinder or prejudice any of the Collateral Agent’s
rights or remedies under this Debenture.

 

Section 5.26                                        Costs and Expenses.

 

(1)                                  Each Obligor, on a joint and several basis, shall pay all reasonable out
of pocket expenses incurred by the Trustee or the Collateral Agent (including
the fees, charges and disbursements of not more than one counsel plus, if
necessary, one local counsel per jurisdiction for the Trustee or the Collateral
Agent), in connection with the enforcement or protection of its rights (i) in
connection with this Debenture and the other Indenture Documents including its
rights under this Section 5.26 (ii) in connection with the Indenture
Documents, the Charge created thereunder or the Charged Property, including all
legal fees, court costs, receiver’s or agent’s remuneration and other expenses
of taking possession of, repairing, protecting, insuring, preparing for
disposition, realizing, collecting, selling, transferring, delivering or
obtaining payment for the Charged Property, and of taking, defending or
participating in any action or proceeding in connection with any of the
foregoing matters or otherwise in connection with the interest of the
Collateral Agent, the Secured Creditors’ (or any one of them) interest in any
Charged Property, whether or not directly relating to the enforcement of this
Debenture and the other Indenture 

 

33

 

Documents, or (iii) in
connection with the issuance of Notes
made under the Indenture, including all such out-of-pocket expenses incurred
during any workout, restructuring or negotiations in respect of such issuance of Notes and (iv) all
documentary and similar taxes and charges in respect of the Indenture
Documents.

 

(2)                                  Each Obligor, on a joint and several basis, shall indemnify the Trustee
(and any sub-trustee thereof), and the Collateral Agent (and any sub-agent
thereof), and their respective Affiliates and each officer, director, employee
or agent thereof (each such person being called an “Indemnitee”)
against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses (including reasonable fees, charges
and disbursements of any counsel for any Indemnitee) incurred by any Indemnitee
or asserted against any Indemnitee by any party hereto or any third party
arising out of, in connection with, or as a result of any action, investigation,
suit or proceeding (whether commenced or threatened) relating to or arising out
of (i) the execution or delivery of this Debenture, any other Indenture  Document, or any amendment, amendment and restatement,
modification or waiver of the provisions hereof or thereof, or any agreement or
instrument contemplated hereby or thereby, the performance by the parties
hereto of their respective obligations hereunder or thereunder or the
consummation of the transactions contemplated hereby or thereby, (ii) any issuance of Notes or the use or proposed use
of the proceeds therefrom, (iii) any actual or alleged presence or Release
or threatened Release of Hazardous Materials on, at, under or from any property
or facility owned, leased or operated by any Credit Party at any time, or any
Environmental Claim related in any way to any Credit Party, or (iv)  any
actual or prospective claim, litigation, investigation or proceeding relating
to any of the foregoing, whether based on contract, tort or any other theory,
whether brought by a third party or by the Issuer or any other Credit Party,
and regardless of whether any Indemnitee is a party thereto; provided that such
indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses (x) are
determined by a court of competent jurisdiction to have resulted from the gross
negligence, bad faith or wilful misconduct of such Indemnitee or (y) result
from a claim brought by any Credit Party against an Indemnitee for breach in
bad faith of such Indemnitee’s obligations hereunder or under any other
Indenture Document, if such Credit Party has obtained a judgment in its favor
on such claim as determined by a court of competent jurisdiction.

 

(3)                                  All amounts due under this Section 5.26 shall be payable not later
than three (3) Business Days after demand therefor.

Reference
is made to the Demand Debenture (as amended, amended and restated, supplemented
or otherwise modified from time to time, the “Demand
Debenture;” capitalized terms used but not otherwise defined herein
shall have the meanings assigned to such terms in the Demand Debenture), dated

LP and Bridge Creek Trucking Ltd.
(each an “Obligor” and together the “Obligors”) in favour of BNY Trust Company of Canada, as collateral agent (in
such capacity and together with any successors and permitted assigns in such
capacity, the “Collateral Agent”).

 

This
Joinder Agreement supplements the Demand Debenture and is delivered by the
undersigned, [                         ] [in its own capacity (“·”) and · as partner/general
partner/managing partner for and on behalf of ·] ([“·” and together with ·,] the “New Obligor”),
pursuant to Section 5.18 of the Demand Debenture. 
The New Obligor hereby agrees to be bound as an Obligor party to the
Demand Debenture by all of the terms, covenants and conditions set forth in the
Demand Debenture to the same extent that it would have been bound if it had
been a signatory Obligor to the Demand Debenture on the date of the Demand
Debenture, on its own behalf and on behalf of any Partnership Obligor in which
it is a partner (other than a limited partner), general partner or managing
partner.  Without limiting the generality
of the foregoing, the New Obligor, in its own personal capacity and in its
capacity as a partner (other than as a limited partner), general partner or
managing partner of any Partnership Obligor in which it is a partner, general
partner or managing partner, grants to the Collateral Agent, for the benefit of
the Secured Creditors, a security interest in, and assigns, mortgages, charges,
hypothecates and pledges to the Collateral Agent, for the benefit of the
Secured Creditors, substantially all of the property of such Obligor and of any
Partnership Obligor in which it is a partner, general partner or managing
partner, of the type and description set forth in Section 3.1 of the
Demand Debenture whether now owned or hereafter acquired.  The New Obligor also expressly assumes all
obligations and liabilities of an Obligor thereunder, on its own behalf and on
behalf of any Partnership Obligor in which it is a partner (other than a
limited partner), 

 

 

general
partner or managing partner.  The New
Obligor hereby makes each of the representations and warranties and agrees to
each of the covenants applicable to the Obligors contained in the Demand
Debenture.

 

This
Joinder Agreement and any amendments, waivers, consents or supplements hereto
may be executed in any number of counterparts and by different parties hereto
in separate counterparts, each of which when so executed and delivered shall be
deemed to be an original, but all such counterparts together shall constitute
one and the same agreement.

 

This
Joinder Agreement will be governed by, interpreted and enforced in accordance
with, the laws of the Province of Alberta and the federal laws of Canada
applicable therein.

 

IN
WITNESS WHEREOF, the New Obligor has caused this Joinder Agreement to be
executed and delivered by its duly authorized officer as of the date first
above written.
