 time to time authorize the creation of Notes hereunder in each case in fully
 registered form within the meaning of United States Temporary Treasury
 Regulation Section 5f.103-1(c)(1). For clarity and avoidance of doubt, the
 Trustee shall be entitled to assume for all purposes of this Indenture that
 any Note issued or to be issued by the Corporation under this Indenture has
 been or will be issued in fully registered form within the meaning of United
 States Temporary Treasury Regulation Section 5f.103-1(c)(1). It is understood
 and agreed, however, that the Trustee, the Corporation and the Guarantor
 shall co-operate in good faith with each other to ensure that that the
 book-entry system maintained by the Trustee for the purposes of determining
 the registered owner of the Notes complies with the requirements of such
 regulations.

 Indenture, interest shall accrue and be payable on such Fixed Rate Notes in
 arrears and in equal semi-annual instalments or if interest is to be
 calculated for a period shorter or longer than a semi-annual period, such
 interest will be computed on the basis of a 365 day year (regardless of the
 actual number of days in that year) and the actual number of days elapsed in
 that period. If the particular Fixed Rate Note specifies that interest shall

| | (e) | Unless otherwise specified
 in the Note, a Note shall not be repayable at the option of the Registered
 Holder of such Note prior to the Stated Maturity of such Note. A Note may specify
 that it is repayable, in whole or in part, at the option of the Registered
 Holder prior to the Stated Maturity of such Note on such date or dates and at
 such price or prices (expressed as a percentage of the principal amount of
 such Note) as are specified in such Note, together with accrued and unpaid
 interest thereon to but excluding the date of repayment. In order for a Note
 (which is by its terms is repayable at the option of the Registered Holder)
 to be repaid, the Trustee must receive, not less than 30 nor more than 45
 days prior to the date fixed for such repayment, at any of its principal
 offices during normal business hours in Toronto a duly completed Option to
 Elect Repayment form on the reverse of such Note. Any such notices shall be
 irrevocable. The repayment option may be exercised by the Registered Holder
 of a Note (which is by its terms repayable at the option of the Registered
 Holder) for less than the entire principal amount of the Note, provided that
 the principal amount which is to be repaid is equal to the Authorized
 Denomination or an integral multiple of the Authorized Denomination and
 provided that the portion of the principal amount of any Note not being
 repaid shall be at least $5,000. All questions as to the validity, eligibility
 (including time of receipt) and acceptance of any Note for repayment will be
 determined by the Trustee, whose determination will be final and binding.

|The Person in whose name
 any Note shall be registered shall be deemed the owner thereof for all
 purposes of this Indenture, subject to the provisions hereof and except as
 otherwise required by law. The Corporation shall cause to be kept by and at
 the principal office of the Trustee in the City of Toronto, a securities
 register in which shall be entered the names and addresses of Registered
 Holders of Notes and the other particulars, prescribed by law, of the Notes
 held by them respectively. For so long as any Notes are transferable only
 through the Book-Based System, CDS & Co. (or such other name as CDS may
 use from time to time as its nominee name for purposes of the Book-Based
 System) shall appear as the only Registered Holder of such Notes on such
 register. The Trustee shall have the right to treat each Person whose name
 appears on such register as the owner of Notes having face amounts and
 Maturity Dates as indicated on such register in respect of such Person and
 for all purposes of this Indenture. Accordingly, the Trustee shall not be
 bound to recognize any transfer, pledge or other disposition of a Note or any
 attempt to transfer, pledge or dispose of a Note, or any beneficial interest
 or equitable or other right or claim with respect thereto, whether or not the
 Trustee shall have actual or other notice thereof, unless such Note shall
 have been transferred on the register. The Corporation shall also cause to be
 kept by and at the principal office of the Trustee in the City of Toronto,
 the register of transfers, and may also cause to be kept by the Trustee or
 such other registrar or registrars and at such other place or places as the
 Corporation may designate with the approval of the Trustee, branch registers
 of transfers in which shall be recorded the particulars of the transfers of
 Notes, registered in that branch register of transfers. No transfer of a Note
 shall be valid unless made on one of the appropriate registers by the
 Registered Holder or his executors or administrators or other legal
 representatives or his or their attorney duly appointed by an instrument in
 writing in form and execution satisfactory to the Trustee upon compliance
 with such requirements as the Trustee and/or other registrar may prescribe,
 and unless such transfer shall have been duly noted on such Note by the
 Trustee or other registrar.

rights against
the Trustee hereunder. Notwithstanding the foregoing, no transfer shall be
registered by the Trustee during the fifteen days immediately preceding any
date fixed for redemption or payment of interest or principal on any Note.

The Registered
Holder of a Note may at any time and from time to time have such Note
transferred at any of the places at which a register of transfer is kept
pursuant to the provisions of this section and in accordance with such
reasonable regulations or requirements as the Trustee may prescribe, and upon
payment of a reasonable fee to be fixed by the Trustee.

The Trustee
and/or any registrar for any of the Notes and/or the Corporation shall not be
charged with notice of or be bound to see to the execution of any trust,
whether express, implied or constructive, in respect of any Note and may
transfer any Note on the direction of the Registered Holder thereof, whether
named as trustee or otherwise, as though that Person were the beneficial owner
thereof.

|2.10 | Form of Notes

It is
acknowledged and agreed that, at the Corporations option, any or all Notes
issued hereunder may be represented in the form of Global Notes, registered in
the name of CDS & Co. as contemplated by, and subject to, section 2.5.

All Global
Notes and Notes not represented by Global Notes shall be issued in registered
form only and shall be substantially in the form set forth in Schedule A
hereto, with such additions, omissions, substitutions and modifications thereto
as the Corporation, with the consent of the Trustee (which consent shall not be
unreasonably withheld), may from time to time approve. Each such Note shall be
serially numbered or numbered in such a way so as to be able to identify the
issuance of securities to which the Note pertains, shall bear such legends as
the Corporation may direct and shall be signed manually on behalf of the
Trustee by a duly authorized officer of the Trustee. No such Note shall be
issued or, if issued, shall be valid or binding on the Corporation until it has
been signed as aforesaid. Any such Note so issued and signed (and Notes
represented by Global Notes so issued and signed) shall be valid and binding
upon the Corporation and shall entitle the holder thereof to all benefits of
this Indenture. Notes shall be issued only in face amounts which are equal to
or in excess of the Authorized Denomination. Each Note shall constitute
evidence of the rights and legal title of the holder in respect of a Note, and
the other rights accorded hereunder to holders and the duty of the Trustee to
perform its obligations hereunder.

the Definitive Notes are to be registered and delivered and the authorized

 registered solely in the name of CDS & Co. (or such other name as CDS
 may use from time to time as its nominee name for purposes of the Book-Based
 System) and represented by one or more Global Notes, the Corporation shall,
 either (i) at least one (1) Business Day prior to each Interest Payment Date,
 deliver or cause to be delivered to the principal office of the Trustee in
 the City of Toronto by wire transfer of immediately available funds the
 amount of interest payable on the Notes on such Interest Payment Date or (ii)
 at least two (2) Business Days prior to each Interest Payment Date, deliver
 or cause to be delivered to the principal office of the Trustee in the City
 of Toronto a certified cheque for the amount of interest payable on the Notes
 on such Interest Payment Date payable to the order of the Trustee and
 negotiable at par. In either such case, the Trustee, upon receipt of the
 funds, shall pay on the Interest Payment Date to an account designated by CDS
 the amount of interest payable on the Notes on such Interest Payment Date (net of any amounts to be withheld by
 applicable law including, without limitation, the Withholding Tax Amount to
 be remitted by the Trustee to the United States Internal Revenue Service in
 accordance with the Administrative Agent Agreement). Any interest earned on
 funds delivered by the Corporation to the Trustee before such funds are paid
 to CDS will belong to the Corporation and shall be paid to the Corporation by
 the Trustee. The delivery of funds by the Corporation to the Trustee as set
 forth above shall satisfy and discharge any liability the Corporation may
 have for the payment of interest due upon the Notes on such Interest Payment
 Date to the extent of the sums represented thereby.

|    | (a)                    | To evidence
the Guarantee to the Registered Holders of Notes as specified in section 3.2,
the Guarantor hereby agrees to endorse upon each Note duly issued hereunder a
guarantee substantially in the form set out in Schedule A hereto with such
appropriate insertions, omissions, substitutions and variations as the
officers of the Guarantor, acting reasonably, executing the same may approve,
such approval to be conclusively evidenced by the certification of the Note.
The form of the Guarantee may include a corresponding French text. In the
event of any contradictions, discrepancy or difference between the English
language text and the French language text of the form of Guarantee, the
English language text shall govern, except where applicable law otherwise
requires. The Guarantee affixed to each Note shall be executed on behalf of
the Guarantor by any of its duly appointed officers, manually or by facsimile
signature. In case any officer of the Guarantor who shall have signed the
Guarantee, manually or by facsimile signature, shall cease to be such officer
before the Note on which the Guarantee is endorsed shall have been certified
by or on behalf of the Trustee or issued by the Corporation, such Note with
the Guarantee endorsed thereon, nevertheless may be certified, delivered and
issued as though the Person who signed the Guarantee had not ceased to be an
officer.

|3.4 | Certificate By Trustee

The Guarantor
agrees that the certification by the Trustee, in the manner provided in this
Indenture, of any Note (whether in temporary or definitive form) shall be
conclusive evidence that the Guarantee endorsed upon such Note has been duly
executed and delivered and is a valid obligation of the Guarantor. The
Guarantor agrees that the issuance by the Corporation of a Note and the
delivery of such Note by the Trustee, after certification by the Trustee in the
manner provided in this Indenture, shall be deemed delivery by the Guarantor of
the Guarantee appearing upon such Note. The certification of the Trustee shall
not be construed as a representation or warranty by the Trustee as to the
validity of the Guarantee.

The
Corporation covenants that it will pay to the Trustee from time to time
reasonable remuneration for its services hereunder and will pay or reimburse
the Trustee upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in the administration or execution of
the trusts hereby created (including the reasonable compensation and the
disbursements of its Counsel and all other advisers, accountants appraisers,
experts and assistants not regularly in its employ), both before any default
hereunder and thereafter until all duties of the Trustee under the trusts
hereof shall be finally and fully performed, except any such expense,
disbursement or advance as may arise from the negligence or bad faith of the
Trustee. Any amount due under this section 4.2 and unpaid 30 days after request
for such payment shall bear interest from the expiration of such 30 days at a

of any default on the part of the Corporation in the performance of any
covenant or condition herein or of the occurrence of any Event of Default,
notice of every such default or Event of Default, as the case may be, unless
the Trustee reasonably believes that it is in the best interests of the
Registered Noteholders to withhold such notice and so informs the Corporation
in writing.

Where notice
of a default or Event of Default has been given and the default or Event of
Default is cured, notice that the default or Event of Default is no longer
continuing shall be given by the Trustee to the holders of the applicable
series or tranche of Notes within five Business Days after the Trustee becomes
aware that the default or Event of Default has been cured.

If the
Corporation shall fail to perform any of its covenants contained in this
Indenture the Trustee may, subject to section 10.1, itself perform any such
covenants capable of being performed by it or its agents, but shall be under no
obligation to do so. All sums so expended or advanced by the Trustee shall be
repayable as provided in section 4.2. No such performance or advance by the
Trustee shall be deemed to relieve the Corporation of any default hereunder.

 Jurisdiction

If an Event of
Default hereunder has occurred and is continuing, in accordance with its
obligations under the terms and conditions of Article 3 hereof the Guarantor
shall, forthwith on

demand by the
Trustee, pay to the Trustee, for the equal benefit of each and every Note in
respect of which there shall be an Event of Default, the principal, premium (if
any), interest (including interest at the then current interest rate borne by
the Notes on amounts in default) and Additional Amounts outstanding.

If an Event of
Default has occurred and is continuing, and if the Guarantor shall fail
forthwith on demand to make good such default, then and so often as any such
default and failure shall happen, the Trustee may in its discretion proceed in
its name as Trustee hereunder in the enforcement of the rights given hereby or
pursuant hereto by any remedy provided by law whether by legal proceedings or
otherwise and to recover from the Guarantor such sums as the Guarantor may be
liable to pay pursuant to the provisions of the Guarantee and any and all sums
so recovered by the Trustee shall be dealt with by the Trustee in the manner
provided in section 5.9 of this Indenture.

The Guarantor
irrevocably and unconditionally submits to the non-exclusive jurisdiction of
(i) the courts and administrative tribunals of the Province of Ontario, and
(ii) any administrative proceeding in the Province of Ontario, in any
proceeding arising out of or related to the distribution of the Notes. The
Guarantor hereby appoints the Corporation as its agent for service of process
in Canada, in respect thereof.

The Guarantor
agrees to pay all reasonable expenses and charges, legal or otherwise
(including the court costs and legal fees), paid or incurred by the Trustee or
any Registered Noteholder in enforcing this Indenture or in enforcing covenants
hereby guaranteed.

|5.3 | Acceleration on Default

If an Event of
Default with respect to Notes of any series or tranche at the time outstanding
occurs and is continuing, then in every such case, unless the principal amount
of the Notes of such series or tranche shall have already become due and
payable, the Trustee or the Registered Holders of not less than 25% in the
principal amount of the outstanding Notes of that series or tranche may declare
the principal amount (or, if the Notes of that series or tranche are discount
Notes, such portion of the principal amount as may be specified in the terms of
that series or tranche), any premium (including any redemption premium, if
applicable) and accrued and unpaid interest of all of the Notes of that series
or tranche to be due and payable immediately, by a notice in writing to the
Corporation (and to the Trustee if given by Registered Holders), and upon any
such declaration such principal amount or specified amount) shall become
immediately due and payable.

At any time
after such a declaration of acceleration with respect to Notes of any series or
tranche has been made and before a judgment or decree for payment of the money
due has been obtained or entered by the Trustee as hereinafter in this Article
provided, the Registered Holders of a majority in principal amount of the
outstanding Notes of that series or tranche, by written notice to the
Corporation and the Trustee, may rescind and annul such declaration and its
consequences if:

 Registered Noteholders of not less than 51% in principal amount of the Notes
 then outstanding shall have the power (in addition to and subject to the
 powers exercisable by Extraordinary Resolution) by instrument in writing to
 instruct the Trustee to waive the default and/or to annul any declaration
 and/or demand made by the Trustee pursuant to section 5.3 and the Trustee,
 subject to funding and an indemnity satisfactory to it, shall thereupon waive
 the default and/or annul such declaration and/or demand upon such terms and
 conditions as such Registered Noteholders may prescribe; and

| | (b) | the Trustee,
 so long as it has not become bound to institute any proceedings hereunder,
 shall have power to waive the default if, in the Trustees opinion based on
 its Counsels opinion, the same shall have been cured or adequate
 satisfaction made therefor, and in such event to annul any such declaration
 and/or demand theretofore made by the Trustee in the exercise of its
 discretion, upon such terms and conditions as to the Trustee may seem
 advisable;

provided,
however, that no act or omission of the Trustee or the Registered Noteholders
in the premises shall extend to or be taken in any manner whatsoever to affect
any subsequent default or the rights resulting therefrom.

The Trustee,
so long as it has not become bound to institute any proceedings hereunder may
waive or authorize any breach or proposed breach of any of the terms,
conditions or provisions of this Indenture or the Notes if, in the opinion of
the Trustee based on the opinion of its Counsel, such breach or proposed breach
is not materially prejudicial to the interests of the holders of the Notes.

 the holders of the Notes by any action, suit, remedy or proceeding authorized

 claims of the Trustee and of the holders of the Notes lodged in any
 bankruptcy, winding-up or other proceedings relative to the Corporation; and

 provided in section 10.1, the Trustee shall exercise or take such one or more
 of the said remedies as the Registered Noteholders Request or Extraordinary
 Resolution may direct or, if such Registered Noteholders Request or
 Extraordinary Resolution contains no direction, as the Trustee may deem
 expedient.

All rights of
action hereunder may be enforced by the Trustee without the possession of any
of the Notes or the production thereof on the trial or other proceedings
relative thereto.

Noteholder or a holder of any interest in the Notes shall have the right to

by this Indenture for the purpose of enforcing any right hereunder or under any
Note or for the execution of any trust or power hereunder or for the
appointment of a liquidator or receiver or for a receiving order under any
bankruptcy legislation or to have the Corporation wound up or to file or prove
a claim in any liquidation or bankruptcy proceedings, unless a Registered
Noteholders Request shall have been given to the Trustee or an Extraordinary
Resolution passed directing the Trustee to institute such action, suit or
proceeding and the funding and indemnity referred to in section 10.1 shall have
been tendered to the Trustee and the Trustee shall have failed to institute
such action, suit or proceeding within 60 days after the later of the (a)
receipt of such request or direction; or (b) receipt of such funds and
indemnity, in such case, but not otherwise, any Registered Noteholder or a holder
of any interest in the Notes acting on behalf of himself and all other
Registered Noteholders or a holder of any interest in the Notes shall be
entitled to take proceedings in any court of competent jurisdiction such as the
Trustee might have taken under section 5.5; it being

understood and
intended that no one or more Registered Noteholders or a holder of any interest
in the Notes shall have any right in any manner whatsoever to affect, disturb
or prejudice the rights hereby created by his or their action, or to enforce
any right hereunder or under any Note except subject to the conditions and in
the manner herein provided, and that all powers and trusts hereunder shall be
exercised and all proceedings at law shall be instituted, had and maintained by
the Trustee, except only as herein provided, and in any event for the equal

|5.7 | Rights and Remedies Cumulative

Except as
otherwise provided with respect to the replacement or payment of mutilated,
destroyed, lost or stolen Notes in section 2.13, no right or remedy herein
conferred upon or reserved to the Trustee or to the Registered Noteholders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at
law or in equity or otherwise. The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

|--- | ----------------------------
|5.8 | Delay or Omission Not Waiver

No delay or
omission of the Trustee or of any other Registered Noteholders to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article 5 to the

ARTICLE 10
CONCERNING THE TRUSTEE

|     |                                                    
|---- | ---------------------------------------------------
|10.1 | Conditions Precedent to Trustees Obligation to Act

The Trustee
shall not be bound to give any notice or do or take any act, action or
proceeding in virtue of the powers conferred on it hereby unless and until it
shall have been required so to do under the terms hereof; nor, subject to any
default which may come to the attention of the Trustee by virtue of the
Corporations compliance with or non-compliance with subsection

---



- 48 -

4.1(e), shall
the Trustee be required to take notice of any default hereunder, other than in
payment of any moneys required by any provision hereof to be paid to it, unless
and until notified in writing of such default, which notice shall distinctly
specify the default desired to be brought to the attention of the Trustee, and
in the absence of any such notice the Trustee may for all purposes of this
Indenture conclusively assume that the Corporation is not in default hereunder
and that no default has been made with respect to the payment of principal or
interest on the Notes or in the observance or performance of any of the
covenants, agreements or conditions contained herein. Any such notice or
requisition shall in no way limit any discretion herein given to the Trustee to
determine whether or not the Trustee shall take action with respect to any
default or take action without any such requisition.

The obligation
of the Trustee to commence or continue any act, action or proceeding for the
purpose of enforcing any right of the Trustee or the holders hereunder shall be
conditional upon such holders furnishing, when required by notice in writing
by the Trustee, sufficient funds to commence or continue such act, action or
proceeding and an indemnity reasonably satisfactory to the Trustee to protect
and hold harmless the Trustee against the costs, charges and expenses and
liabilities to be incurred thereby and any loss and damage it may suffer by
reason thereof.

None of the
provisions contained in this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur financial liability in the performance of
any of its duties or in the exercise of any of its rights or powers unless
indemnified as aforesaid.

The Trustee
may, before commencing or at any time during the continuance of any such act,
action or proceeding, require the Registered Noteholders at whose instance it
is acting to deposit with the Trustee the Notes held by them, for which Notes
the Trustee shall issue receipts.

|     |         
|---- | --------
|10.2 | Evidence

Whenever it is
provided in this Indenture, with reference to any application to the Trustee
for the certification and delivery of Notes or other action hereunder, that the
Corporation shall deposit with the Trustee resolutions, certificates, opinions,
requests, orders or other documents, it is intended that the truth, accuracy
and good faith at the time of the granting of such application (or on the
effective date of any such certificate or report, as the case may be) of the
facts and opinions stated in all documents so deposited shall, in each and
every such case, be conditions precedent to the right of the Corporation to
have such application granted. The Trustee may rely and shall be protected in
acting upon any such documents deposited with it in purported compliance with
any such provision or for any other purpose hereof, but may in its discretion
require further evidence before acting or relying thereon.

The Trustee may rely and shall
be protected in acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, letter, telegram, cablegram,
facsimile or other paper or document believed by it to be genuine and to have
been signed, sent or presented by or on behalf of the proper party or parties,
and shall not be required to inquire as to the veracity, accuracy or adequacy
of or be bound by any notice or direction to the contrary by any persons other
than a person entitled to give such notice.

|---- | --------------------
|10.3 | Experts and Advisers

The Trustee
may employ or retain such Counsel, accountants, appraisers, or other experts or
advisers as it may reasonably require for the purpose of discharging its duties
hereunder and shall exercise reasonable care in their selection and ongoing
supervision. The Trustee may pay remuneration for all services performed for it
in the discharge of the trust hereof without taxation for all costs and fees of
any Counsel, solicitor or attorney and may recover such expenses pursuant to
Section 10.8.

The Trustee
may act and shall be protected in acting in good faith on the opinion or advice
of or information obtained from any Counsel, accountant, appraiser or other
expert or adviser, including information obtained from the Corporation, whether
retained or employed by the Corporation, the Registered Noteholders or by the
Trustee, in relation to any matter arising in the administration of the trusts
hereof.

Any opinion of
Counsel may be based, insofar as it relates to factual matters or information
which is in the possession of the Corporation, upon the certificate or opinion
of or representations by an officer or officers of the Corporation unless such
Counsel knows that the certificate, opinion or representation upon which such
Counsels opinion may be based is, or in the exercise of reasonable care should
have known that the same was, erroneous.

Whenever it is
required by any provision hereof that a certificate or opinion be signed by a
person acceptable to the Trustee, the acceptance by the Trustee of the
certificate or opinion signed by such person shall be sufficient evidence that
the signer is acceptable to the Trustee.

|10.4 | Documents, Moneys, etc., Held by Trustee

Any
securities, documents of title or other instruments that may at any time be
held by the Trustee subject to the trusts hereof may be placed in the deposit
vaults of the Trustee or of any Canadian chartered bank or deposited for
safekeeping with any such bank. Unless herein otherwise expressly provided, any
moneys so held, pending the application or withdrawal thereof under any
provisions of this Indenture, may be deposited in the name of the Trustee in
any Canadian chartered bank at the rate of interest (if any) then current on
similar deposits or, with the consent of the Corporation as evidenced by
Written Notice, may be (i) deposited in the deposit department of the Trustee
or any other loan or trust company authorized to accept deposits under the laws
of Canada or a province thereof, or (ii) invested and reinvested in securities
issued or guaranteed by the Government of Canada or of any province thereof,
maturing not more than one year from the date of investment. All interest or
other income received by the Trustee in respect of such deposits and investments
shall belong to the Corporation, unless an Event of Default shall have occurred
and be continuing, in which case all such interest and income shall be held by

|10.8 | Indemnity

In addition to
and without limiting any other protection of the Trustee hereunder or otherwise
by law, the Corporation hereby indemnifies and saves harmless the Trustee and
its officers, directors, representatives and employees from and against any and
all liabilities, losses, costs, actions, claims, damages or demands (other than
taxes) whatsoever which may be brought against the Trustee or which it may
suffer or incur as a result of or arising out of the performance of its duties
and obligations under this Indenture, including without limitation, those
arising out of or related to actions taken or omitted to be taken by the
Trustee contemplated hereby, legal fees and disbursements on a solicitor and
client basis and costs and expenses incurred in connection with the enforcement
of this indemnity which the Trustee may suffer or incur, whether at law or in equity,
in any way caused by or arising directly or indirectly, in respect of any act,
deed, matter or thing whatsoever made, done, acquiesced in or omitted in or
about in relation to the execution of its duties as Trustee, provided that the
Trustee, its directors, representatives, officers and employees have acted
honestly and in good faith and have not acted negligently or in wilful
disregard of the Trustees obligations under this Indenture. It is understood
and agreed that this indemnification shall survive the termination or discharge
of this Indenture or the resignation or removal of the Trustee. The Trustee
shall not be liable for any action suffered by it to be taken or omitted
excepting its own negligence or wilful misconduct.

|     |                       
|---- | ----------------------
|10.9 | Replacement of Trustee

The Trustee
may resign its trust and be discharged from all further duties and liabilities
hereunder by giving to the Corporation not less than 60 days notice in writing
or such shorter notice as the Corporation may accept as sufficient. The Registered
Noteholders, by Extraordinary Resolution, shall have power at any time to
remove the Trustee and to appoint a new Trustee. In the event of the Trustee
resigning or being removed as aforesaid or being dissolved, becoming bankrupt,
going into liquidation or otherwise becoming incapable of acting hereunder, the
Corporation shall forthwith appoint a new Trustee unless a new Trustee has
already been appointed by the Registered Noteholders; failing such appointment
by the Corporation, the retiring Trustee or any Registered Noteholder may apply
to the Ontario Superior Court of Justice (the Court), on such notice as the Court may direct, for the
appointment of a new Trustee; but any new Trustee so appointed by the
Corporation or by the Court shall be subject to removal as aforesaid by the
Registered Noteholders. Any new Trustee appointed under these provisions must
be a corporation authorized to carry on the business of a trust company in the
Province of Ontario. On any new appointment, the new Trustee shall be vested
with the same powers, rights, duties and responsibilities as if it had been
originally named herein as Trustee without any further assurance, conveyance,
act or deed; but there shall be immediately executed, at the expense of the
Corporation, all such conveyances or other instruments as may, in the opinion
of Counsel, be necessary or advisable for the purpose of assuring the same to
the new Trustee. At the request of the Corporation or the new Trustee, the
retiring Trustee, upon payment of the amounts, if any, due to it pursuant to
section 4.2, shall duly assign, transfer and deliver to the new Trustee all
property and money held and all records kept by the retiring Trustee hereunder
or in connection herewith.

Any
corporation into which the Trustee, or its corporate trust department, may be
merged or with which it may be consolidated or any corporation resulting from
any merger, consolidation or amalgamation to which the Trustee shall be a
party, shall be the successor trustee under this

Indenture
without the execution of any instrument or any further act and shall succeed to
all obligations and liabilities of the Trustee hereunder.

|      |                        
|----- | -----------------------
|10.10 | No Conflict of Interest

The Trustee
represents to the Corporation that at the date of the execution and delivery of
this Indenture no material conflict of interest exists in the Trustees role as
fiduciary hereunder and agrees that in the event of a material conflict of
interest arising hereunder the Trustee shall, within 30 days after becoming aware
that such a material conflict of interest exists, either eliminate such
material conflict of interest or resign its trust hereunder. If any such
material conflict of interest exists or hereafter shall exist, the validity and
enforceability of the Indenture and the Notes shall not be affected in any
manner whatsoever by reason thereof.

|      |                           
|----- | --------------------------
|10.11 | Representations by Trustee

The Trustee
represents to the Corporation that at the time of the execution and delivery
hereof it has all necessary power to accept its trusts and carry out its
obligations hereunder.

Subject to the
preceding paragraph, the Trustee, in its personal or any other capacity, may
buy, lend upon and deal in securities of the Corporation and generally may
contract and enter into business transactions with the Corporation or any of
its Affiliates without being liable to account for any profit made thereby.
