     Obligations or any other indulgences which the Holders may grant to the

     available to, or a discharge of, the Guarantor, the Company or any other
     person in respect of the Guaranteed Obligations or the Guarantor in respect
     of the Guarantee.

         SECTION 4. REMEDIES. The guarantee set forth in Section 2 constitutes a

Obligations before being entitled to payment or performance hereunder. The
Guarantor hereby waives the right to require the Holders to join the Company in
any action brought hereunder or to commence any action against or obtain any
judgment against the Company or to pursue any other remedy or enforce any other
right. The Guarantor further agrees that nothing contained herein or otherwise
shall prevent the Holders from pursuing concurrently or successively all rights
and remedies available to them at law and/or in equity or under any Debt
Agreement, and the exercise of any of their rights or the completion of any of
their remedies shall not constitute a discharge of any of Guarantor's
obligations hereunder.

amount of the Guaranteed Obligations and all other amounts payable by it to the
Holders hereunder forthwith after demand therefor is made in writing to it and

be entitled to claim repayment against the Company until the claims of the
Holders against the Company in respect of the Guaranteed Obligations have been
repaid in full; and in the case of the liquidation, winding-up or bankruptcy of
the Company (whether voluntary or compulsory) or in the event that the Company
shall make a bulk sale of any of the Company's assets within the provisions of
any bulk sales legislation or makes an assignment for the benefit of creditors
or the assets of the Company are distributed to creditors for any other reason,
the Holders shall have the right to rank in priority to the Guarantor for their
full claims in respect of the Guaranteed Obligations and receive all
distributions and other payments in respect thereof until their claims in
respect of the Guaranteed Obligations have been paid in full, and the Guarantor
shall continue to be liable, less any payments made by or on behalf of the
Guarantor, for any balance which may be owing to the Holders by the Company. If
any amount shall be paid to the Guarantor on the account of any subrogation
rights at any time when all the Guaranteed Obligations shall not have been paid
in full, such amount shall be held in trust for the benefit of the Holders and
shall forthwith be paid to the Holders.

owing by the Company to the Holders, and any payments received by the Guarantor
on account of such Corporate Indebtedness at a time when any Default or Event of
Default exists (as each such term is defined in the governing Debt Agreement)
shall be collected and received by the Guarantor in trust and paid over to the
Holders without impairing or releasing any obligations of the Guarantor
hereunder. The Guarantor shall not assign the Corporate Indebtedness nor any
part thereof to any person other than to a subsidiary of the Company which has
provided a guarantee to the Holders in respect of the Guaranteed Obligations in
the form and substance of this Guarantee, without the prior written consent of
the Holders.

         SECTION 8. SUSPENSION OF GUARANTOR RIGHTS. The Guarantor agrees that so
long as any obligations remain outstanding hereunder, whether present or future,

the performance of any of its obligations hereunder:

(a)  to be indemnified by the Company;
(b)  to claim contribution from any other guarantor of the debts, liabilities or
     obligations of the Company; or
(c)  to take the benefit (in whole or in part and whether by way of subrogation
     or otherwise) of any rights of the Holders under the governing Debt
     Agreements.

         SECTION 9. WAIVERS. The Guarantor hereby waives, to the extent
permitted by applicable law, (i) notice of acceptance of this Guarantee by the
Holders and any and all notices and demands of every kind which may be required
to be given by any statute, rule or law, (ii) any defense, right of set-off or
other claim which the Guarantor may have against the Company or which the
Guarantor or the Company may have against the Holders, (iii) presentment for
payment, demand for payment, notice of nonpayment or dishonor, protest and
notice of protest, diligence in collection and any and all formalities which
otherwise might be legally required to charge the Guarantor with liability,

the Holders to inform the Guarantor of any facts the Holders may now or
hereafter know about the Company, the Debt or the transactions contemplated by
the governing Debt Agreement, it being understood and agreed that the Holders
have no duty to so inform the Guarantor, that the Guarantor is fully responsible
for being and remaining informed by the Company of all circumstances bearing on
the existence or creation, or the risk of nonpayment

guaranteed by the Company prior to such amendment or termination remains
outstanding, no such amendment which adversely affects the holders of such
series of Debt (or, if not issued as a series, such other Debt) or any such
termination shall become effective with respect to such series of Debt (or such
other Debt) unless (i) at least two nationally recognized statistical rating
agencies that have rated such series of Debt (or such other Debt) prior to such
amendment or termination confirm in writing that their ratings for such series
of Debt (or such other Debt) in effect immediately prior to such amendment or
termination will not be downgraded as a result of such amendment or termination
(or, in the case of any such series of Debt (or such other Debt) that is not so
rated, such series of Debt (or such other Debt) shall be treated in the same
manner as any series of similar Debt (or other similar Debt) that is so rated);

accordance with the provisions of the instrument evidencing such series of Debt
(or such other Debt) or any indenture or similar instrument relating thereto; or

such series of Debt consent (or, consents) in writing to such amendment or
termination.

Agreement; and (ii) the date on which the Company or the Guarantor shall have
performed and satisfied in full the Guaranteed Obligation. This Guarantee shall
continue to be effective or be reinstated, as the case may be, if at any time

the Holders contest the order requiring the return of such payment, all as
though such payment had not been made.

         SECTION 12. INTEREST ACT (CANADA). The Guarantor acknowledges that, for
the purposes of the Interest Act (Canada), (i) whenever any interest or fee
applicable to the Guaranteed Obligations is calculated using a rate based on a

when expressed as an annual rate, is equivalent to (x) the applicable rate based
on a year of 360 days or 365 days, as the case may be; (ii) the principle of
deemed reinvestment of interest does not apply to any interest calculation in
respect of the Guaranteed Obligations; and (iii) the rates of interest

liability of the Guarantor hereunder and this Guarantee shall extend to any
person, firm or Company acquiring or from time to time caring on the business of
the Company.

         SECTION 14. NO RECOURSE. Any right of subrogation acquired by the
Guarantor by reason of payment under or pursuant to this Guarantee shall not be
exercised until the Guaranteed Obligations and other amounts due to the Holders
hereunder have been paid or repaid in full and shall be no greater than the
right held by the Holders, and the Guarantor shall have no recourse against the
Holders for any irregularity or defect in the manner or procedure by which the
Holders make demand or pursue any rights or remedies they may have.

         SECTION 15. REPRESENTATIONS AND WARRANTIES. The Guarantor represents
