allocated costs of in-house legal counsel, accounting, consulting, brokerage or
other similar professional fees or expenses, and any fees or expenses associated
with any travel or other costs relating to any appraisals or examinations
conducted in connection with the obligations hereunder, provided that Borrower
shall not have to pay any such expenses in excess of $5,000, and the amount of
all such expenses shall, until paid, bear interest at the rate applicable to
principal hereunder. The Borrower shall also pay all expenses of the Lender in
connection with the waiver or amendment of this Note and the administration,
default or collection of any amount due under this Note or other obligations or
administration, default, collection in connection with the Lender's exercise,
preservation or enforcement of any of its rights, remedies or options hereunder,
including, without limitation, fees of outside legal counsel or the allocated
costs of in-house legal counsel, accounting, consulting, brokerage or other

any travel or other costs relating to any appraisals or examinations conducted
in connection with the obligations hereunder, and the amount of all such
expenses shall, until paid, bear interest at the rate applicable to principal
hereunder.

10. SET-OFF. Regardless any means of obtaining repayment of the obligations
hereunder, any deposits, balances or other sums credited by or due from the
Lender to the Borrower may, at any time and from time to time, without notice to
the Borrower or compliance with any other condition precedent now or hereafter
imposed by statute, rule of law, or otherwise (all of which are hereby expressly
waived) be set off, appropriated, and applied by the Lender against any and all
obligations of the Borrower to the Lender or any of its affiliates in such
manner as the Lender in its sole discretion may determine, and the Borrower
hereby grants to the Lender a continuing security interest in such deposits,
balances or other sums for the payment and performance of all such obligations.

11. NO WAIVERS OF LENDER'S RIGHTS. No failure or delay by the Lender in
exercising any right, power or privilege hereunder or under any other documents
or agreements executed in connection herewith shall operate as a waiver thereof;
nor shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies in this Note provided are cumulative and not exclusive of
any rights or remedies otherwise provided by agreement or law.

12. NO IMPAIRMENT. The Borrower will not, by amendment of its charter document
or through any reorganization, recapitalization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Lender, but will at times
in good faith assist in the carrying out of all the provisions of this Note and
in the taking of all such action as may be necessary or appropriate in order to
protect the rights of the Lender.

13. LIMITATION ON INTEREST. Notwithstanding any other provision of this Note,
interest on the indebtedness evidenced by this Note is expressly limited so that
in no contingency or event whatsoever, whether by acceleration of the maturity
of this Note or otherwise, shall the interest contracted for, charged or
received by the Lender exceed the maximum amount permissible under applicable
law. If from any circumstances whatsoever fulfillment of any provisions of this
Note or of any other document evidencing, securing or pertaining to the
indebtedness evidenced hereby, at the time performance of such provision shall
be due, shall involve transcending the limit of validity prescribed by law,
then, ipso facto, the obligation to be fulfilled shall be reduced to the limit
of such validity, and if from any such circumstances the Lender shall ever
receive anything of value as interest or deemed interest by applicable law under
this Note or any other document evidencing, securing or pertaining to the
indebtedness evidenced hereby or otherwise an amount that would exceed the
highest lawful rate, such amount that would be excessive interest shall be
applied to the reduction of the principal amount owing under this Note or on
account of any other indebtedness of the Borrower to the Lender, and not to the
payment of interest, or if such excessive interest exceeds the unpaid balance of
principal of this Note and such other indebtedness, such excess shall be
refunded to the Lender. In determining whether or not the interest paid or
payable with respect to any indebtedness of the Borrower to the Lender, under
any specific contingency, exceeds the highest lawful rate, the Borrower and the
Lender shall, to the maximum extent permitted by applicable law, (a)
characterize any non-principal payment as an expense, fee or premium rather than
as interest, (b) exclude voluntary prepayments and the effects thereof, (c)
amortize, prorate, allocate and spread the total amount of interest throughout
the term of such indebtedness so that the actual rate of interest on account of
such indebtedness does not exceed the maximum amount permitted by applicable
law, and/or (d) allocate interest between portions of such indebtedness, to the
end that no such portion shall bear interest at a rate greater than that
permitted by applicable law. The terms and provisions of this paragraph shall
control and supersede every other conflicting provision of this Note and all
other agreements between the Borrower and the Company

<PAGE>

14. AMENDMENTS. Neither this Note nor any provision hereof may be amended,
waived, discharged or terminated except by a written instrument signed by the
Lender and, in the case of amendments, by the Borrower.

15. BINDING EFFECT OF NOTE. This Note shall be binding upon and inure to the
benefit of the Borrower and the Lender and their respective successors and
assigns; provided that neither the Borrower nor the Lender may assign or
transfer its rights or obligations hereunder. Notwithstanding the foregoing,
Lender may transfer its rights and obligations under this Note to one or more of
its affiliates.

16. PARTIAL INVALIDITY. The invalidity or unenforceability of any one or more
phrases, clauses or sections of this Note shall not affect the validity or
enforceability of the remaining portions of it.

17. CAPTIONS. The captions and headings of the various sections and subsections
of this Note are provided for convenience only and shall not be construed to
modify the meaning of such sections or subsections.

18. ENTIRE AGREEMENT. This Note and the documents and any agreements executed in
connection herewith constitute the final agreement of the parties hereto and
supersede any prior agreement or understanding, written or oral, with respect to
the matters contained herein and therein.

THIS NOTE HAS BEEN EXECUTED AND DELIVERED IN THE CITY OF TORONTO, STATE OF
ONTARIO, CANADA. THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, EXCLUDING CONFLICT OF LAWS
PRINCIPLES THAT WOULD CAUSE THE APPLICATION OF LAWS OF ANY OTHER JURISDICTION.
