ARTICLE 1
INTERPRETATION

1.1 DEFINED TERMS. As used in this agreement, including the recital and the
schedules, unless there is something in the subject matter or the context
inconsistent therewith, the following terms shall have the following
meanings:

(1) "ACCOMMODATION" means:

(a) an Advance by a Lender made on the occasion of a Borrowing
pursuant to an Accommodation Request (whether given or deemed to
be given) or otherwise made or deemed to have been made pursuant
hereto;

(b) the creation of Bankers' Acceptances on the occasion of a
Drawing pursuant to an Accommodation Request;

(d) includes an Advance and a Bankers' Acceptance resulting from a
Rollover or Conversion (whether requested or deemed to have been
requested hereunder) or otherwise effected pursuant hereto.

Each type of Borrowing and each type of Issuance is a "TYPE" of
Accommodation, as are Bankers' Acceptances.

(2) "ACCOMMODATION REQUEST" means a notice of request for a Borrowing
and/or a Drawing substantially in the form of schedule 2 annexed
hereto, or such other form as the Administrative Agent may from time
to time specify.

(4) "ADVANCE" means an advance of monies made or deemed to have been

Dollar Advance shall be designated a "PRIME RATE ADVANCE" and a US
Dollar Advance shall be designated from time to time, as requested
or deemed to have been requested by the Borrower, a "LIBOR ADVANCE"
or a "BASE RATE ADVANCE". Each of a Prime Rate Advance, a LIBOR

(5) "AFFILIATE" means, with respect to any person (the "FIRST PERSON"),
any other person which directly or indirectly controls (or is a
member of a group which directly or
9
- 3 -

indirectly controls), or is under common control with, or is
controlled by, the first person. Notwithstanding the foregoing,
neither the Administrative Agent nor any Lender shall be deemed to
be an affiliate of the Borrower solely by reason of its agency role
or lending relationship.

(6) "APPLICABLE MARGIN" means, in respect of a type of Borrowing and in
respect of Drawings and fees, the corresponding margin or fee
(expressed as basis points (0.01 %) per annum) set forth in schedule

disposition (or series of related sales, leases, transfers or
dispositions) of property or other assets (each referred to for the
purposes of this definition as a "DISPOSITION") by or on behalf of
an MDA Party (including any disposition by means of a merger,
consolidation or similar transaction, but for greater certainty
excluding a writedown of goodwill).

(8) "ASSIGNEE" shall have the meaning ascribed thereto in section
14.8(3)(b).

(9) "BANKERS' ACCEPTANCE" means a depository ▇▇▇▇, as defined by the
Depository Bills and Notes Act (Canada) drawn by the Borrower,
denominated in Canadian Dollars and accepted by a Lender as a
bankers' acceptance, as evidenced by such Lender's endorsement
thereof at the request of the Borrower pursuant to an Accommodation
Request and includes a Bankers' Acceptance resulting from a
Conversion or Rollover.

(10) "BASE RATE" means, at any time, the greater of:

Bank from time to time as the reference rate of interest it
charges to customers for US Dollar loans made by it in Canada;
and

(b) the sum of (i) the Federal Funds Effective Rate multiplied by
365 (or 366) and divided by 360, plus (ii) 50 basis points per
annum;

as to which a certificate of the Administrative Agent, absent
manifest error, shall be conclusive evidence from time to time.
With each quoted or published change in such rate aforesaid of Royal
Bank there shall be a corresponding change in the rate of interest
payable under this agreement, should such changed rate exceed that
set forth in paragraph (b) of this definition, all without the
necessity of any notice thereof to the Borrower or any other person.

(11) "BENEFICIARY" means, in respect of any Letter of Credit, the
beneficiary specified therein.

(12) "BILATERAL L/C"means a letter of credit or letter of guarantee
issued by a Lender at the request and upon the indemnity of the

only after the Borrower has consulted with the

credit or letter of guarantee under one of the Credit Facilities,
together with all indemnities, applications and reimbursement
agreements in connection therewith.

(13) "BORROWER" means ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ and Associates Ltd.

therewith, a day (other than Saturday or Sunday) on which banks

Saturday or Sunday) on which banks are open for business in

auditors of such person).
11
- 5 -

(19) "CDOR RATE" means, on any day, the annual rate of interest
determined by the Administrative Agent which is equal to the average
of the yield rates per annum (calculated on the basis of a year of
365 days) applicable to Canadian Dollar bankers' acceptances having,
where applicable, identical issue and comparable maturity dates as
the Bankers' Acceptances proposed to be issued by the Borrower
displayed and identified as such on the "CDOR Page" (or any display
substituted therefor) of Reuters Monitor Money Rates Service at
approximately 10:00 a.m. (Toronto time) on that day or, if that day
is not a Business Day, then on the immediately preceding Business
Day (as adjusted by the Administrative Agent after 10:00 a.m.
(Toronto time) to reflect any error in a posted rate of interest or

ARTICLE 2
THE CREDIT FACILITIES

2.1 CREDIT FACILITIES.

(1) Commitment. The Credit Facilities to be made available,
subject to the terms and conditions of this agreement, are as
follows:

(a) the RTC Facility, to be made available to the Borrower by
the Lenders on a revolving basis during the Revolving
Period and on a non-revolving basis during the
Non-Revolving Period, in the principal amount of up to but
not exceeding $110 million (or the Equivalent Amount in US
Dollars);

(b) the LC Facility, to be made available to the Borrower by
the Lenders on a non-revolving basis in the aggregate
Face Amount of up to but not exceeding $50 million; and

(c) the Term Facility, to be made available to the Borrower by
the Lenders on a non-revolving basis in the principal
amount of up to but not exceeding $30 million.

Subject to the terms and conditions herein set forth, each
Lender shall make Accommodations available under each of the
RTC Facility, the LC Facility and the Term Facility pro rata on
the basis of their respective Commitments as set forth in
schedule 1 hereto.

Subject to section 2.11, in no event shall a Lender be
obligated to make Accommodations available under a Credit
Facility if after making such Accommodations the Principal
Outstanding of that Lender's Accommodations under all Credit
Facilities would exceed that Lender's Commitment.

Each Lender shall make Accommodations available to the Borrower
through its relevant Lending Branch.

(2) Purposes. The Credit Facilities shall be used only for the
following purposes:

(a) in the case of the RTC Facility, for general corporate
purposes, including without limitation for acquisitions;

(b) in the case of the LC Facility, for the Issuance of
Letters of Credit in favour of CSA with respect to the
construction of Radarsat II; and
31
- 25 -

(c) in the case of the Term Facility, for general corporate
purposes, including without limitation for acquisitions
and to refinance Debt incurred in connection with past
acquisitions.

(3) Accommodations. Subject to the terms and conditions of this
agreement, Accommodations shall be made available under the
Credit Facilities as follows:

RTC FACILITY

Prime Rate Advances
Base Rate Advances
LIBOR Advances
Bankers' Acceptances
Letters of Credit (in both Cdn. Dollars and US Dollars)
LC FACILITY

Letters of Credit (in Cdn. Dollars only)

TERM FACILITY

Prime Rate Advances
Base Rate Advances
LIBOR Advances
Bankers' Acceptances

provided that:

(a) the aggregate Face Amount of EDC-Insured Letters of Credit
issued under the RTC Facility shall not at any time exceed
$25 million (or the Equivalent Amount in US Dollars); not
later than ten days before the end of each Financial
Quarter, the Borrower shall designate in writing to the
Administrative Agent the amount, up to $25 million, that
will be available by way of EDC-Insured Letters of Credit
under the RTC Facility; provided that, if the Borrower
shall fail to give such notice, the availability by way of
EDC-Insured Letters of Credit will be deemed to be $25
million.

(b) Letters of Credit shall be available under the LC Facility
in two tranches, namely (1) EDC-Insured Letters of Credit
up to an aggregate Face Amount at any time not exceeding
$25 million, and (2) other Letters of Credit up to an
aggregate Face Amount at any time not exceeding $25
million and at all times
32
- 26 -

accommodations under the LC Facility shall be apportioned
equally between EDC-Insured Letters of Credit and other
Letters of Credit; and

(4) Minimum Amounts. Subject to the Majority Lenders in any
specific instance waiving such requirement, the following
minimum amounts shall apply in respect of certain Borrowings
and Drawings requested under each Accommodation Request:

(a) each Bankers' Acceptance shall be in a Face Amount of
$100,000 or a whole multiple thereof;

(b) the aggregate of the Face Amount of Bankers' Acceptances
requested in a Drawing shall be at least $5 million and a
whole multiple of $1 million;

(d) the aggregate of the Base Rate Advances and LIBOR Advances
requested shall be at least US$5 million (and, in the case
of LIBOR Advances, whole multiples of US$1 million).

(5) Revolving Repayments. Each of the LC Facility, the RTC
Facility (during the Non-Revolving Period) and the Term
Facility shall not revolve, and amounts repaid or prepaid
thereunder may not be the subject of any further Accommodations
(other than by way of Conversions or Rollovers). During the
Revolving Period, the RTC Facility is a so-called "revolving"
facility and amounts repaid thereunder may be made the subject
of a further Accommodation (subject to compliance with the
terms and conditions of this agreement); repayments of the RTC
Facility in accordance with its revolving nature during the
Revolving Period shall be made on one Business Day's notice for
Prime Rate Advances and Base Rate Advances, and three Business
Days' notice for LIBOR Advances.

Any portion of the Commitments of the Lenders allocated to the
Term Facility not made the subject of an Accommodation on or
before December 31, 2000 shall be cancelled as at such date.

(6) Swingline Advances. In the event that the Borrower has a
requirement for a Prime Rate Advance or a Base Rate Advance in
same day funds in
33
- 27 -

a minimum amount of $1 million and multiples of $100,000 (or in
each case the Equivalent Amount in US Dollars) up to $10
million (or the Equivalent Amount in US Dollars in the
aggregate), the Borrower may (subject to satisfaction of
applicable terms and conditions hereof) obtain such Advance (in
this section 2.1(6), a "SWINGLINE ADVANCE") from the
Administrative Agent alone on a same day basis if the request
is received by the Administrative Agent before 11:00 a.m.
(Toronto time). Each Swingline Advance shall be deemed to
constitute a utilization of the RTC Facility from each Lender
pro rata on the basis of their respective Commitments (and the
risk of each Swingline Advance, and payments on account
thereof, shall be allocated and shared among the Lenders in
accordance with section 14.1) and may not be outstanding more
than five Business Days. The Borrower shall, on or before the
fifth Business Day forthwith following the making of a
Swingline Advance, repay such Swingline Advance in full,
together with all accrued or unpaid interest, either from its
own resources or with the proceeds of an Accommodation, failing
which the Borrower shall be deemed to have delivered to the
Administrative Agent at the close of business in Vancouver on
such fifth Business Day an Accommodation Request requesting a
Prime Rate Advance or a Base Rate Advance (as the case may
be)in the amount of such Swingline Advance. The proceeds of
the funding by the other Lenders under such Accommodation
Request shall be applied by the Administrative Agent to repay
the Administrative Agent that portion of the Swingline Advance
that does not represent its pro rata share thereof.

(7) Extensions. On an annual basis, the Borrower may request an
extension of the 364 day Revolving Period for an additional 364
days, by giving notice to the Administrative Agent for delivery
to each Lender not more than 90 and not less than 60 days prior
to the end of the then current Revolving Period. No later than
25 days prior to the end of the then current Revolving Period,
each Lender shall notify the Agent of its election (which
election may be made in its sole and absolute discretion) to
extend or not extend the then applicable Revolving Period.
Failure by a Lender to so notify the Administrative Agent shall
be deemed to be an election by such Lender not to extend.
Subject to the consent of the Majority Lenders, the
Administrative Agent may extend the Revolving Period for an
additional 364 day period, such extension applying only to
those Lenders which provided their consent to the extension.
In the case of any Lender not consenting (or being deemed not
to consent) to an extension (a "NON-CONSENTING LENDER"), its
Commitment allocated to the RTC Facility shall be reduced as at
the end of the then current Revolving Period by an amount equal
to the difference between such Commitment so allocated and the
Principal Outstanding owed to it under the RTC Facility at such
time.
34
- 28 -

At its option, the Borrower may:

(a) as to the entire Commitment of the Non-Consenting Lender
or only its Commitment allocated to the RTC Facility,
replace such Non-Consenting Lender with one or more
Lenders or by a new Lender satisfactory to the Borrower
and the Administrative Agent; or

(b) prepay the Obligations owed to such Non-Consenting Lender
under the RTC Facility.

If and to the extent that the portion of the Commitments of the
Non-Consenting Lenders under the RTC Facility are not assumed
or prepaid, the Principal Outstanding owed to each
Non-Consenting Lender under the RTC Facility shall mature and
be payable in full on the second anniversary of the last day of
the then current Revolving Period.

2.2 REPAYMENT.

(1) RTC Facility Repayment. The Principal Outstanding under the RTC
Facility will be repaid in full on its Final Maturity Date.

(2) LC Facility Repayment. The Principal Outstanding under the LC
Facility will be repaid in full on its Final Maturity Date.

(3) Term Facility Repayment. The Principal Outstanding under the Term
Facility will be repaid in full on its Final Maturity Date.

(4) Interest. At the same time as any mandatory or voluntary repayment
or prepayment of principal is made hereunder, the Borrower shall
also pay all accrued and unpaid interest on the principal amount
being repaid or prepaid.

(5) Foreign Exchange Fluctuations. If at any time the Principal
Outstanding under any Credit Facility, as calculated by the
Administrative Agent as at the first day of a calendar month, shall
exceed 105% of the relevant maximum amount set forth in section
2.1(1) by virtue of a change in the Equivalent Amount in Cdn.
Dollars of Accommodations made in US Dollars, the Borrower shall
within five Business Days following demand therefor by the
Administrative Agent at the Borrower's election either (a) pay to
the Administrative Agent such amount as is required to reduce such
Principal Outstanding to, or below, such relevant maximum amount,
or (b) pay such excess amount to the Administrative Agent, to be
held by the Administrative Agent as cash collateral security for
the Obligations.

requirement) shall be in an aggregate minimum amount of $5 million
and multiples in excess thereof of $1 million or in the full amount
of such Principal Outstanding.

(3) Order. Any prepayment under section 2.4(2) shall reduce the
Commitments of the Lenders in respect of the relevant Credit

by the Administrative Agent on the basis of a year of 365 days

(b) interest based on LIBOR shall be made by the Administrative
Agent on the basis of a year of 360 days and the actual number
of days (including the first day but excluding the last day)
occurring in the period for which such interest is payable.

All computations of fees shall be made by the Administrative Agent
on the basis of a year of 365 days or, in the case of a leap year,
366 days and the actual number of days (including the
37
- 31 -

first day but excluding the last day) occurring in the period for
which such fees are payable. Each determination by the
Administrative Agent of an amount of interest or fees payable by
the Borrower hereunder shall be conclusive and binding for all
purposes, absent demonstrated error.

(2) Interest Act (Canada). For purposes of disclosure pursuant to the
Interest Act (Canada), the yearly rate of interest to which any
rate of interest based on LIBOR is equivalent may be determined by
multiplying the applicable rate by a fraction, the numerator of
which is the number of days to the same calendar date in the next
calendar year (or 365 days if the calculation is made as of
February 29) and the denominator of which is 360.

2.7 FEES. The Borrower shall pay to the Administrative Agent the following
fees, calculated as follows:

(1) in respect of each of the RTC Facility and the LC Facility, a
facility fee (for the account of the Lenders pro rata on the basis
of their respective Commitments) payable by the Borrower at the
rate per annum equal to the applicable percentage set forth in the
definition of Applicable Margin on the aggregate Commitments
allocated to such Credit Facility; such fee shall be payable in
Cdn. Dollars, calculated daily from the Closing Date to the
applicable Final Maturity Date, and payable quarterly in arrears on
the first day of each of January, April, July, and October and on
such Final Maturity Date;

(2) in respect of the Term Facility, a standby fee (for the account of
the Lenders pro rata on the basis of their respective Commitments)
payable by the Borrower at the rate per annum equal to the
applicable percentage set forth in the definition of Applicable
Margin on the difference between the aggregate Commitments
allocated to such Credit Facility and the Principal Outstanding
thereunder; such fee shall be payable in Cdn. Dollars, calculated
daily from the Closing Date to December 31, 2000, and payable
quarterly in arrears on each of July 1, 2000, October 1, 2000 and
January 1, 2001; and

(3) the fees agreed with the Administrative Agent in a letter of even
date.

agreement, each amount owed by the Borrower to a Lender which is not paid
when due (whether at stated maturity, on demand, by acceleration or
otherwise) shall bear interest (both before and after judgment), from the
date on which such amount is due until such amount is paid in full,
payable on demand, at a rate per annum equal at all times to the Base Rate
(in the case of amounts denominated in US Dollars) or the Prime Rate (in
the case of amounts denominated in Cdn. Dollars), in each case plus two
(2%) percent per annum in excess of the Applicable Margin.

2.9 WHERE BORROWER FAILS TO PAY. Unless the Administrative Agent has been
notified in writing by the Borrower at least one Business Day prior to the
date on which any payment
38
- 32 -

to be made by the Borrower hereunder is due that the Borrower does not
intend to remit such payment, the Administrative Agent may, in its
discretion, assume that the Borrower has remitted such payment when so due
and the Administrative Agent may, in its discretion and in reliance upon
such assumption, make available to each Lender on such payment date an
amount equal to the portion of such payment which is due to such Lender
pursuant to this agreement. If the Borrower does not in fact remit such
payment to the Administrative Agent, the Administrative Agent shall
promptly notify each Lender and each such Lender shall forthwith on demand
repay to the Administrative Agent an amount equal to the portion of such
assumed payment made available to such Lender, together with interest
thereon until the date of repayment thereof at a rate determined by the
Administrative Agent (such rate to be conclusive and binding on such
Lender) in accordance with the Administrative Agent's usual banking
practice for similar advances to financial institutions of like standing
as such Lender but in no event greater than the Prime Rate.

2.10 ACCOUNT DEBIT AUTHORIZATION. The Borrower authorizes and directs the
Administrative Agent, in its discretion, to automatically debit, by
mechanical, electronic or manual means, the Borrower Account and all other
bank accounts of the Borrower maintained with Royal Bank (for so long as
Royal Bank is Administrative Agent hereunder) for all amounts due and

hereunder comprised in the Obligations.

2.11 ADMINISTRATIVE AGENT'S DISCRETION ON ALLOCATION. In the event that it is
not practicable to:

(1) allocate an Accommodation pro rata in accordance with sections 3.2,
4.1(2) or 5.4 by reason of the occurrence of circumstances
described in Article 11;

(2) allocate a Drawing among the Lenders in accordance with section
4.1(2) such that the aggregate amount of Bankers' Acceptances
required to be accepted hereunder complies with the minimum amounts
or increments set forth in section 2.1(4); or

(3) allocate an Issuance among the Lenders such that the Letter of
Credit required to be issued by each Lender complies with the
reasonable commercial requirements of the Borrower or the
Beneficiary;

the Administrative Agent is authorized by the Borrower and each Lender to
make such allocation as the Administrative Agent determines in its sole
and unfettered discretion may be equitable in the circumstances. All fees
in respect of any such Drawing or Issuance shall be adjusted, as among the
Lenders, by the Administrative Agent accordingly.

2.12 ROLLOVER AND CONVERSION.
39
- 33 -

(1) General. Subject to the terms and conditions of this agreement,
the Borrower may from time to time request that any Bankers'
Acceptance or type of Advance or any portion thereof be rolled over
or converted in accordance with the provisions hereof.

(2) Request. Each request by the Borrower for a Rollover or Conversion
shall be made by the delivery of a duly completed and executed
Accommodation Request to the Administrative Agent and the
provisions of Articles 3 or 4 shall apply to each request for a
Rollover or Conversion as if such request were a request thereunder
for a Borrowing or a Drawing (as the case may be).

(3) Effective Date. Each Rollover or Conversion of a LIBOR Advance or
Bankers' Acceptance shall be made effective as of, in the case of a
LIBOR Advance, the last day of the subsisting Interest Period and,
in the case of a Bankers' Acceptance, the maturity date applicable
thereto.

(4) Failure to Elect. If the Borrower does not deliver an
Accommodation Request at or before the time required by section
2.12(2) and:

(a) in the case of a Bankers' Acceptance fails to give two Business
Days prior notice that it will pay to the Administrative Agent
for the account of the applicable Lender (or Participant) the
Face Amount thereof on the maturity date or if the Borrower
gives such notice but fails to act in accordance with it, the
Borrower shall be deemed to have requested a Conversion of the
Face Amount thereof to a Prime Rate Advance and all of the
provisions hereof relating to a Prime Rate Advance shall apply
thereto; or

(b) in the case of a LIBOR Advance, fails to give three Business
Days prior notice that it will pay to the Administrative Agent
for the account of the applicable Lender the principal amount
thereof at the end of the relevant Interest Period or if the
Borrower gives such notice but fails to act in such accordance
with it, the Borrower shall be deemed to have requested a
Conversion of such LIBOR Advance to a Base Rate Advance, and

ARTICLE 3
ADVANCES

3.1 ADVANCES.
40
- 34 -

(1) Commitment. Each Lender agrees (on a several basis with the other
Lenders under each relevant Credit Facility, up to the amount of
such Lender's Commitment allocated to such Credit Facility), on the
terms and conditions herein set forth, from time to time on any
Business Day prior to the relevant Final Maturity Date, to make
Advances under each relevant Credit Facility.

(2) Amounts. The aggregate principal amount of each Borrowing shall
comply with section 2.1(4).

3.2 MAKING THE ADVANCES.

(1) Notice. Each Borrowing shall be made on at least three Business
Days' (in the case of LIBOR Advances) or one Business Day's (in the
case of other types of Advance) prior notice given not later than
10:00 a.m. (Vancouver time) by the Borrower to the Administrative
Agent, and the Administrative Agent shall give to each Lender
prompt notice thereof and of such Lender's rateable portion of each
type of Borrowing to be made under the Borrowing. Each such notice
of a Borrowing shall be given by way of an Accommodation Request or
by telephone (confirmed promptly in writing), with the same
information as would be contained in an Accommodation Request,
including the requested date of such Borrowing and the aggregate
amount of each type of Advance comprising such Borrowing.

(2) Lender Funding. Each Lender shall, before 10:00 a.m. (Vancouver
time) on the date of the requested Borrowing, deposit to the
Payment Account in same day funds such Lender's rateable portion
(subject to section 2.11) of each type of Advance comprising such
Borrowing (in Canadian Dollars, in the case of Prime Rate Advances,
and in US Dollars, in the case of LIBOR Advances and Base Rate
Advances). Promptly upon receipt by the Administrative Agent of
such funds and upon fulfilment of the applicable conditions set
forth in Article 6, the Administrative Agent will make such funds
available to the Borrower by debiting such account (or causing such
account to be debited), and by crediting the Borrower Account (or
causing such account to be credited) with such Advances.

(3) Failure by Lender to Fund. Unless the Administrative Agent shall
have received notice from a Lender prior to the date of any
Borrowing that such Lender will not make available to the
Administrative Agent such Lender's rateable portion of each type of
Advance comprising such Borrowing, the Administrative Agent may
assume that such Lender has made each such portion available to the
Administrative Agent on the date of such Borrowing in accordance
with section 3.2(2) and the Administrative Agent may, in reliance
upon such assumption, make available to the
41
- 35 -

Borrower on such date corresponding amounts. If and to the extent
that such Lender shall not have made its rateable portions
available to the Administrative Agent, such Lender shall pay such
corresponding amounts to the Administrative Agent forthwith on
demand. If such Lender shall pay such corresponding amounts to the
Administrative Agent, the amounts so paid shall constitute such
Lender's rateable portions of such Borrowing for the purposes of
this agreement. The Administrative Agent shall also be entitled to
recover from such Lender interest on such corresponding amounts,
for each day from the date such amounts were made available by the
Administrative Agent to the Borrower until the date such amounts
are repaid to the Administrative Agent, at a rate per annum equal
to:

(a) in the case of Prime Rate Advances, the Bank of Canada rate in
effect from time to time; and

(b) in the case of Base Rate Advances and LIBOR Advances, such rate
as is customary from time to time for interbank payments of
this nature;

together with the Administrative Agent's reasonable administrative
fee. If such Lender shall not pay such corresponding amounts to
the Administrative Agent forthwith on demand, the Borrower shall
pay such corresponding amounts (together with accrued and unpaid
interest at the applicable rate herein set forth for each type of
Advance) to the Administrative Agent within two Business Days of
demand being made upon it.

(4) Ibid. The Administrative Agent shall notify the Borrower of the
failure of any Lender to make an Advance if:

(a) such failure has not been remedied within seven days; or

(b) the Administrative Agent reasonably believes that such failure
was caused by any reason other than a technical failure or as a
result of a defect in the arrangements hereunder for funding
Advances.

The Administrative Agent shall not be liable to the Borrower or any
Lender in respect of notice given or not given pursuant to this
section 3.2(4). In the event of the continuing failure by any
Lender (in this section 3.2(4), the "DEFAULTING LENDER") to make an
Advance, the Borrower and the Administrative Agent shall use their
reasonable best efforts to arrange for one or more other persons
(in this section 3.2(4), the "ASSUMING LENDER") reasonably
satisfactory to the Borrower and the other Lenders to assume all or
a portion of the relevant Commitments and acquire the outstanding
Accommodations and other rights and interests of the defaulting
Lender hereunder. The assuming Lender and defaulting Lender shall
execute all such documents as may be reasonably required by the
Administrative Agent and the Borrower to effect such assumption and
acquisition.
42
- 36 -

3.3 INTEREST ON ADVANCES. The Borrower shall pay interest on the unpaid
principal amount of each Advance at the following rates per annum:

(1) Prime Rate Advances. If and so long as such Advance is a Prime
Rate Advance, at a rate per annum equal at all times to the sum of
the Prime Rate in effect from time to time plus the Applicable
Margin, calculated daily and payable in Cdn. Dollars in arrears:

(a) monthly on the last Business Day of each month; and

(b) when such Prime Rate Advance becomes due and payable in full or
is the subject of a Conversion.

(2) Base Rate Advances. If and so long as such Advance is a Base Rate
Advance, at a rate per annum equal at all times to the sum of the
Base Rate in effect from time to time plus the Applicable Margin,
calculated daily and payable in U.S. Dollars in arrears:

(a) monthly on the last Business Day of each month; and

(b) when such Base Rate Advance becomes due and payable in full or
is the subject of a Conversion.

(3) LIBOR Advances. If and so long as such Advance is a LIBOR Advance,
at a rate per annum equal at all times during each Interest Period
for such LIBOR Advance to the sum of LIBOR for such Interest Period
plus the Applicable Margin, calculated daily and payable in US
Dollars:

(a) at the end of each Interest Period (except where such Interest
Period exceeds three months in duration, in which case such
interest shall be payable on the dates falling every three
months following the commencement of the Interest Period and,
finally, at the end of such Interest Period); and

(b) when such LIBOR Advance becomes due and payable in full or is
the subject of a Conversion.

(confirmed promptly in writing) with the same information as would

Drawing Date and the Face Amounts of the Bankers' Acceptances.

(2) Maturity. The Borrower shall not request in an Accommodation
Request a term for Bankers' Acceptances which would end on a date
subsequent to the relevant Final Maturity Date or that would
conflict with any repayment stipulated herein.

(1) Form. Each Bankers' Acceptance shall:

(a) be in a Face Amount allowing for conformance with section
4.1(2);

(b) be dated the Drawing Date;

on a Business Day which occurs approximately one, two, three or
six months after the date thereof, subject to availability; and

(d) be in a form satisfactory to the relevant Lender.

(2) Applicability of DBNA. It is the intention of the parties that
each Bankers' Acceptance accepted by a Lender under this agreement
shall be issued in the form of a "depository ▇▇▇▇" (as that term is
defined in the Depository Bills and Notes Act (Canada) (the
"DBNA")), be deposited with The Canadian
44
- 38 -

Depository for Securities Limited and be made payable to "CDS &
Co." The Administrative Agent and the Lenders shall effect the
following practices and procedures and, subject to the approval of
the Majority Lenders, establish and notify the Borrower and the
Lenders of any additional procedures, consistent with the terms of
this agreement and the requirements of the DBNA, as are reasonably
necessary to accomplish this intention:

(a) each Bankers' Acceptance accepted and purchased by a Lender
hereunder shall have marked prominently and legibly on its face

will be removed; and

(c) that Bankers' Acceptance shall not be marked with any words
prohibiting negotiation, transfer or assignment of it or of an
interest in it.

(3) Grace. The Borrower hereby waives presentment for payment and any
other defence to payment of any amounts due in respect of any
Bankers' Acceptance, and hereby renounces, and shall not claim, any
days of grace for the payment of any Bankers' Acceptance.

4.4 COMPLETION OF BANKERS' ACCEPTANCE. Upon receipt of the notice from the
Administrative Agent pursuant to section 4.2(1), each Lender is thereupon
authorized to execute Bankers' Acceptances as the duly authorized attorney
of the Borrower pursuant to a Power of Attorney, in accordance with the
particulars provided by the Administrative Agent.

on the Drawing Date specified by the Borrower in the applicable Drawing
Notice, credit the Payment Account with the applicable Discount Proceeds
of the Bankers' Acceptances purchased by that Lender to the Agent Bank for
the account of the Borrower.

4.6 STAMPING FEE. The Borrower shall pay to each Lender a stamping fee in
Canadian dollars. Such stamping fee shall be payable by the Borrower in
advance, on the Drawing Date, and shall be calculated on the Face Amount
of such Bankers' Acceptances on the basis of the number of days in the
term of such Bankers' Acceptances (including the Drawing Date but
excluding the maturity date) at a rate per annum equal to the applicable
percentage set forth in the definition of Applicable Margin.

4.7 PAYMENT AT MATURITY. The Borrower shall pay to the Administrative Agent,
and there shall become due and payable, on the maturity date for each
Bankers' Acceptance an
45
- 39 -

amount in same day funds equal to the Face Amount of the Bankers'
Acceptance. The Borrower shall make each payment hereunder in respect of
Bankers' Acceptances by deposit of the required funds to the Payment
Account. Upon receipt of such payment, the Administrative Agent will
promptly thereafter cause such payment to be distributed to the Lenders in
like funds relating to the payment of Bankers' Acceptances rateably (based
on the proportion that the Face Amount of Bankers' Acceptances accepted by
a Lender maturing on the relevant date bears to the Face Amount of
Bankers' Acceptances accepted by all the Lenders maturing on such date).
Such payment to the Administrative Agent shall satisfy the Borrower's
obligations under a Bankers' Acceptance to which it relates and the
accepting institution shall thereafter be solely responsible for the
payment of such Bankers' Acceptance.

Unless the Borrower notifies the Administrative Agent prior to 10:00 a.m.
(Vancouver time) two Business Days' immediately prior to the maturity date
of a Bankers' Acceptance that the Borrower intends to pay to the
Administrative Agent the Face Amount thereof with funds other than the
proceeds of Advances, (i) the Borrower shall be deemed to have given an
Accommodation Request to the Administrative Agent requesting the Lenders
to make a Prime Rate Advance on such maturity date in an amount equal to
such Face Amount, and (ii) the Lenders shall, on such maturity date, make
such Prime Rate Advance and apply the proceeds thereof to payment of such
Face Amount.

condition precedent to each Lender's obligation to accept Bankers'
Acceptances hereunder, the Borrower shall have delivered to such Lender a
duly executed Power of Attorney, enabling such Lender to execute and
deliver Bankers' Acceptances for and on behalf of the Borrower. No Lender
shall be liable for any damage, loss or other claim arising by reason of
any loss or improper use of any draft or Bankers' Acceptances executed in
blank except any such damage, loss or claim arising by reason of the gross
negligence, wilful misconduct or fraud of such Lender or its officers,
employees, agents or representatives or arising by reason of such Lender
or its officers, employees, agents or representatives failing to exercise
such care in the custody and safekeeping of such draft or Bankers'
Acceptances as it would exercise in the custody and safekeeping of similar
property owned by it.

4.9 PREPAYMENTS. Except as required by section 2.2(5) or 4.10, no payment of
the Face Amount of a Bankers' Acceptance shall be made by the Borrower to
a Lender prior to the maturity date thereof. Any such required payment
made before the applicable maturity date shall be held by the
Administrative Agent as cash collateral security to provide for or to
secure payment of the Face Amount of such outstanding Bankers' Acceptance
upon maturity. Any such required payment made before the applicable
maturity date by the Borrower to the Administrative Agent shall satisfy
the Borrower's obligations under the Bankers' Acceptance to which it
relates. The accepting institution shall
46
- 40 -

thereafter be solely responsible for the payment of the Bankers'
Acceptance and shall indemnify and hold the Borrower harmless against any
liabilities, costs or expenses incurred by the Borrower as a result of any
failure by such Lender or Participant to pay the Bankers' Acceptance in
accordance with its terms.

4.10 DEFAULT. Upon the occurrence of an Event of Default and the
Administrative Agent declaring the Obligations to be due and payable
pursuant to section 12.2, and notwithstanding the date of maturity of any
outstanding Bankers' Acceptances, an amount equal to the Face Amount of
all outstanding Bankers' Acceptances which the Lenders are required to
honour shall thereupon forthwith become due and payable by the Borrower to
the Administrative Agent.

4.11 OLD SYSTEM ISSUERS. The parties acknowledge that certain Lenders ("OLD
SYSTEM ISSUERS") may prefer to effect a Drawing by accepting a
non-interest bearing ▇▇▇▇ of exchange, as defined by the Bills of Exchange
Act (Canada), rather than accepting a Bankers' Acceptance in the form of a
"depository ▇▇▇▇" as defined in the DBNA. The parties agree that should
an Old System Issuer become a Lender, the parties will enter into such
agreement supplemental hereto and in amendment hereof as the
Administrative Agent may reasonably require to accommodate such Old System
Issuer completing and accepting drafts executed in blank by or on behalf
of the Borrower.

of the Lenders;

(c) the Fronting Lender shall be paid by the Borrower, at the time

(2) the existence of any claim, set-off, defence or other right which
the Borrower may have at any time against a Beneficiary or any
transferee of any Letter of Credit (or any persons for whom any
such transferee may be acting), any Lender or any other person,
whether in connection with this agreement, the Credit Facility
Documents, the transactions contemplated herein and therein or any
unrelated transaction (including any underlying transaction between
the Borrower or an affiliate and the Beneficiary of such Letter of
Credit);

(3) any draft, demand, certificate or any other document presented
under any Letter of Credit proving to be forged, fraudulent or
invalid in any respect or any statement therein being untrue or
inaccurate in any respect;

(4) payment by an issuing Lender under any Letter of Credit against

pay and save each issuing Lender and its directors, officers,
employees, agents and representatives harmless from and against any
and all claims, demands, liabilities, damages, losses, costs,
charges and expenses (including legal fees and expenses) which the
indemnitee may incur or be subject to as a consequence, direct or
indirect, of:

(a) the issuance of any Letter of Credit, other than as a result of
the gross negligence or wilful misconduct of the indemnitee, in
the case of a standby letter of credit or letter of guarantee,
or breach of the standards of reasonable care specified in the
Uniform Customs, in the case of a commercial letter of credit;
or

(b) the failure of the indemnitee to honour a drawing under any
Letter of Credit as a result of any act or omission, whether
rightful or wrongful, of any present or future de jure or de
facto government or governmental authority (all such acts or
omissions called in this section 5.8, "GOVERNMENT ACTS").

(2) Risk. As between the Borrower and each issuing Lender, the
Borrower assumes all risks of the acts and omissions of, or misuse
of the Letters of Credit issued by such issuing Lender, by the
respective Beneficiaries of such Letters of Credit and, without
limitation of the foregoing, such issuing Lender shall not be
responsible for:

(a) the form, validity, accuracy, genuineness or legal effect of
any document submitted by any party in connection with the
application for and issuance of such Letters of Credit, even if
it should in fact prove to be in any or all respects invalid,
inaccurate, fraudulent or forged;

(b) the invalidity or insufficiency of any instrument transferring
or assigning or purporting to transfer or assign any such
Letter of Credit or the rights or benefits thereunder or
proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason;

(c) errors, omissions, interruptions or delays in transmission or
delivery of any messages, by mail, cable, telegraph, telex or
otherwise, whether or not they are in cipher;

(d) errors in interpretation of technical terms;

(e) any loss or delay in the transmission or otherwise of any
document required in order to make a drawing under any such
Letter of Credit or of the proceeds thereof;

(f) the misapplication by the Beneficiary of any such Letter of
Credit of the proceeds of any drawing under such Letter of
Credit; and

(g) any consequences arising from causes beyond the control of such
issuing Lender, including any Government Acts.

None of the above shall affect, impair or prevent the vesting of
any of the Lenders' rights or powers hereunder. No action taken or
omitted by the issuing Lender under or in connection with any
Letter of Credit issued by it or the related certificates, if taken
or omitted in good faith, shall put such issuing Lender under any
resulting liability to the Borrower (provided that such issuing
Lender acts in accordance with the standards of reasonable care
specified in the Uniform Customs, in the case of a commercial
letter of credit, and without gross negligence, in the case of a
standby letter of credit or letter of guarantee).

5.9 DEFAULT. Upon the occurrence of an Event of Default and the
Administrative Agent declaring the Obligations to be due and payable
pursuant to section 12.2, and notwithstanding the expiration date of any
outstanding Letters of Credit, an amount equal to the Face Amount of all
outstanding Letters of Credit, and all accrued and unpaid fees owing by
the Borrower in respect of the issuance of Letters of Credit pursuant to
section 5.4, if any, shall thereupon forthwith become due and payable by
the Borrower to the Administrative Agent and, except for any amount
payable in respect of unpaid fees as aforesaid, such amount shall be held
by the Administrative Agent as cash collateral security to provide for or
to secure payment of the amounts payable under such Letters of Credit in
respect of any drawing thereunder.

The Borrower shall pay to the Administrative Agent the aforesaid amount in
respect of both any Letter of Credit outstanding hereunder and any Letter
of Credit which is the subject matter of any order, judgment, injunction
or other such determination (in this section 5.9, a "JUDICIAL ORDER")
restricting payment by the issuing Lender under and in accordance with
such Letter of Credit or extending such issuing Lender's liability under
such Letter of Credit beyond the expiration date stated therein. Payment
in respect of each such Letter of Credit shall be due in the currency in
which such Letter of Credit is stated to be payable.

(a) by reason of any actions or omissions of or by the indemnitee
or any receiver appointed by or at the request of the
Administrative Agent or the Lenders in operating the Collateral
during the course of realization of the Security, unless such
actions or omissions are found to have been conducted or
omitted, as applicable:

(i) in the course of operating such Collateral in
substantially the same manner as the same was operated
while it was being operated by the relevant MDA Party; or

(ii) in accordance with good industry practice as in effect at
the time of such operations of the indemnitee or the
receiver; or

(b) after the Collateral shall have been disposed of by the
Administrative Agent or the Lenders or any receiver to any
third party or parties in the course of realization on the
Security; except where such Claims arise by reason of any act
or omission of or by the relevant MDA Party, or of or by the
Administrative Agent or the Lenders or a receiver (if the
Administrative Agent or the Lenders or the receiver would have
been entitled to indemnification hereunder if such Claims had
been raised prior to such disposition), occurring prior to the
disposition.

The obligations of the Borrower under this section 10.1(12) shall
survive the payment and performance of the Obligations.

(13) Material Contracts. It will comply with, and diligently enforce,
all material obligations under material contracts, save where
failure to do so neither has, nor could reasonably be expected to
have, an MAE, and without limiting the generality of the foregoing
will use reasonable commercial efforts to cure any matter referred
to in a notice given under section 10.1(9)(f).

(14) Acquisitions. The Borrower: (a) will provide 15 Business Days'

the material
67

terms of all material agreements entered into or to be
entered into, in each case if requested by the
Administrative Agent; and

(iii) such other information as the Administrative Agent shall
reasonably request; and

(b) where such transaction involves an acquisition of or investment
in a Non-Recourse Subsidiary or Special Subsidiary in excess of the
threshold (as defined in the next sentence), the Borrower shall not
proceed unless and until it shall receive the written approval of
the Lenders, which approval will not be unreasonably withheld. For
the purposes of the foregoing, the "threshold" at any time shall be
25% of Equity as determined in accordance with the financial
statements most recently delivered to the Administrative Agent
under section 10.1(8).

(15) Title. Except for disposition permitted hereby, it will maintain
and, as soon as reasonably practicable, defend and take all action

the Liens of the Security.

non-speculative purposes.

of the Administrative Agent, duly execute and deliver, or cause to
be duly executed and delivered, to the Administrative Agent such
further instruments and do and cause to be done such further acts
as may be necessary or proper in the reasonable opinion of the
Administrative Agent to carry out more effectually the provisions
and purposes of this agreement and the other Credit Facility
Documents.

10.2 NEGATIVE COVENANTS. Until the Obligations are paid and satisfied in full
and this agreement has been terminated, and in addition to any other
covenants herein set forth, the Borrower covenants and agrees that it will
not take any of the actions set forth in this section 10.2 or permit or
suffer same to occur without the prior written consent of the Lenders.

legal effect satisfactory to the Lenders the obligations of

Documents to which such MDA Party is a party;

person is directly or indirectly owned by the Borrower;

material contract, where such action has or could reasonably be
expected to have an MAE.

(5) Financial Year. Neither it nor any Designated Subsidiary will
change its Financial Year.

(6) Sale of Assets. Neither it nor any Designated Subsidiary will

otherwise) to any person other than another MDA Party or a
wholly-owned subsidiary of the Borrower at any time in excess of
(for all MDA Parties together) $10 million.

(10) Ibid. The Borrower will not make any loan to, or guarantee of the
indebtedness of, or otherwise provide financial assistance to any

70
- 64 -

(11) Net Position. The aggregate liabilities (excluding amounts owed
to it by any of its subsidiaries which are consolidated with the
Borrower under normal course funding arrangements) owed to the
Borrower by its affiliates (which term shall for this purpose
include any person that is controlled directly or indirectly by the
Borrower and another person on a 50/50 basis), which affiliates are
not Designated Subsidiaries or Non-Recourse Subsidiaries, net of
the aggregate liabilities owed by the Borrower to such affiliates
(excluding management fees and borrowed monies owed by the
Borrower) will not exceed $5 million at any time; provided that the

other Credit Facility Document, the Administrative Agent may, in its sole
discretion acting reasonably, and shall upon the instructions of the
Majority Lenders, perform any of the said covenants capable of being
performed by the Administrative Agent and, if any such covenant requires
the payment or expenditure of money, the Administrative Agent may make
such payment or expenditures with its own funds or with money borrowed for

performance under this section 10.3 shall relieve the Borrower from any
Event of Default.

ARTICLE 11
CHANGES IN CIRCUMSTANCES

11.1 ILLEGALITY. If the enactment of any applicable Law in Canada or any
province or territory or other political subdivision thereof, or any
change therein or in the interpretation or application thereof by any
Official Body or compliance by a Lender with any guideline, official
directive, request or direction (whether or not having the force of Law)
of any Official Body in Canada or any province or territory or other
political subdivision thereof, hereafter makes it unlawful for a Lender to
make, fund or maintain any type of Accommodation or to give effect to its
obligations in respect of such type of Accommodation, such Lender may, by
written notice thereof to the Borrower and to the Administrative Agent,
declare its obligations under this agreement in respect of such type of
Accommodation to be terminated, whereupon the same shall forthwith
terminate, and the Borrower shall within the time required by such Law (or
at the end of such longer period as such Lender at its discretion has
agreed) repay or effect a Conversion of the Principal Outstanding in
respect of such type of Accommodation from such Lender, and shall pay all
accrued interest and fees payable hereunder and all Increased Costs
incurred in connection with the termination or Conversion of such type of
Accommodation.
72
- 66 -

11.2 CIRCUMSTANCES REQUIRING DIFFERENT PRICING. If, on or before any date on
which an interest rate is to be determined on the basis of LIBOR, either:

(1) the Administrative Agent determines that it will not be possible to
determine LIBOR for the applicable Interest Period or in the
applicable amounts; or

(2) the Administrative Agent determines or receives notice from a
Lender that LIBOR will not adequately reflect the cost of making,
funding or maintaining LIBOR Advances for the applicable Interest
Period;

then, the Administrative Agent shall forthwith give notice of such event
to the Borrower and each Lender, whereupon the obligations of the Lenders
to make LIBOR Advances to the Borrower shall be suspended until the
Administrative Agent gives notice to the Borrower and the Lenders that the
circumstances giving rise to such determination no longer exist.

11.3 IBID. If the Administrative Agent determines or receives notice from a
Lender that, by reason of circumstances affecting financial markets inside
or outside Canada, deposits of US Dollars are unavailable to one or more
Lenders in such markets, then,

(1) it shall so notify the Borrower and all Lenders and the right of
the Borrower to select any affected type of Accommodation shall be
suspended;

(2) if any affected type of Accommodation is not yet outstanding, any
applicable Notice shall be cancelled insofar as it relates to that
type of Accommodation and that type of Accommodation requested
therein shall not be made in that form, without affecting the right
of the Borrower to request another type of Accommodation; and

(3) if any affected type of Accommodation is already outstanding at any
time when the right of the Borrower to select such type of
Accommodation is suspended, it shall upon ten days' notice to the
Borrower become a Prime Rate Advance by Conversion, in the case of
a LIBOR Advance on the last day of the then current Interest Period
applicable thereto (or on such earlier date as may be required to
comply with applicable Law, and upon payment of all Increased Costs
arising therefrom).

11.4 INCREASED COSTS. If:

(1) the enactment or amendment of any Law or any change in the
interpretation or application thereof by any Official Body; or

(2) compliance by any Lender with any amendment or change to any
existing directive, request or requirement (whether or not having
the force of Law) of any Official Body (including, without
limitation, the Bank for International
73
- 67 -

Settlements' Paper on Capital Convergence, as implemented in Canada
by the Office of the Superintendent of Financial Institutions'
Release dated August 19, 1988 and any further or other document),
or with any new such directive, request or requirement;

shall have the effect of:

(3) increasing the cost to such Lender of performing its obligations
under this agreement or in respect of any Accommodation, including
the costs of maintaining any capital, reserve or special deposit
requirements with respect to this agreement or any Accommodation or
with respect to its obligations hereunder or thereunder;

(4) requiring such Lender to maintain or allocate any capital
(including a requirement affecting such Lender's allocation of
capital to its obligations) or additional capital in respect of its
obligations under this agreement or in respect of any Accommodation
or otherwise reducing the effective return to such Lender under
this agreement or in respect of any Accommodation or on its total
capital as a result of entering into this agreement or making any
Accommodation;

(5) reducing any amount payable to it by or in an amount it deems
material (other than a reduction resulting from a higher rate of
income or capital Tax or other special Tax relating to such
Lender's income or capital in general); or

(6) causing such Lender to make any payment or to forgo any return on
or calculated by reference to any amount received or receivable by
such Lender under this agreement or in respect of any
Accommodation;

such Lender may give notice to the Borrower (with a copy to the
Administrative Agent) specifying the nature of the event giving rise to
such additional cost, reduction, payment or forgone return and the
Borrower shall promptly pay such amounts as such Lender may specify to be
necessary to compensate it for any such additional cost, reduction,
payment or forgone return. A certificate setting out, in reasonable
detail, the amount of any such additional cost, reduction, payment or
forgone return, submitted in good faith by such Lender to the Borrower,
shall be conclusive and binding for all purposes absent demonstrated
error.

If such circumstances continue in effect for 60 consecutive days, on
request from the Borrower, the Borrower and the Administrative Agent shall
use their reasonable best efforts to arrange for one or more other persons
(in this section 11.4, the "ASSUMING LENDER") reasonably satisfactory to
the Borrower and the other Lenders to assume all or a portion of the
relevant Commitments and acquire the outstanding Accommodations and other
rights and interests of the affected Lender hereunder. The assuming
Lender and affected Lender shall execute all such documents as may
74
- 68 -

be reasonably required by the Administrative Agent and the Borrower to
effect such assumption and acquisition. Failing such assumption and
acquisition, the Borrower may effect a prepayment and cancellation of the
relevant Commitments of the affected Lender (without reducing or prepaying
the Commitment(s) of any other Lender(s));

11.5 INDEMNIFICATION.

(1) Matching Funds. The Borrower shall promptly pay to each Lender any
amounts required to compensate such Lender or its Participants for
any breakage or similar cost, loss, cost of redeploying funds or
other cost or expense suffered or incurred by such Lender or
Participant as a result of:

(a) any payment being made by the Borrower in respect of a LIBOR
Advance or a Bankers' Acceptance (due to acceleration hereunder
or a mandatory repayment or prepayment of principal or for any
other reason) on a day other than the last day of an Interest
Period or the maturity date applicable thereto; provided that,
where the event giving rise to such payment is a mandatory
repayment or prepayment, the Borrower may at its option instead
deposit the amount of the repayment or prepayment to a
segregated account pending expiry of the existing Interest
Period or (as the case may be) maturity of outstanding Bankers
Acceptances, and the monies in such segregated account shall be
applied by the Administrative Agent to the required repayment
or prepayment on the expiry of such Interest Period or maturity
of such Bankers Acceptance;

(b) the Borrower's failure to give notice in the manner and at the
times required hereunder; or

(c) the failure of the Borrower to fulfil or honour, before the
date specified for any Accommodation, the applicable conditions
set forth in Article 6 or to accept an Accommodation after
delivery of a Notice in the manner and at the time specified in
such Notice.

A certificate of such Lender submitted to the Borrower (copy to the
Administrative Agent) as to the amount necessary to so compensate
such Lender or its Participants shall be conclusive evidence,
absent demonstrated error, of the amount due from the Borrower to
such Lender.

(2) General. Subject to section 10.1(12), the Borrower agrees to
indemnify the Administrative Agent, the Lenders and their
respective affiliates, and the directors, officers and employees of
each of them, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever
which may
75
- 69 -

be imposed on, incurred by, or asserted against the indemnitees or
any of them, related to or arising out of the transactions
contemplated hereunder or under any other Credit Facility Document;
provided that no amount shall be payable under this section 11.5(2)
to the extent that same arises out of the gross negligence or
wilful misconduct of an indemnified person, or out of a breach by
it of the terms of this agreement or any other Credit Facility
Document.

11.6 TAXES, COSTS, ETC.

(1) Gross-Up. Any and all payments by the Borrower under this
agreement or any other Credit Facility Document shall be made free
and clear of and without deduction or withholding for Taxes unless
such Taxes are required by Law to be deducted or withheld. If the
Borrower shall be required by Law to deduct or withhold any Taxes
from or in respect of any sum payable hereunder or thereunder:

(a) the sum payable shall be increased as may be necessary so that
after making all required deductions or withholdings (including
deductions or withholdings applicable to additional amounts
paid under this section) the relevant Lender receives an amount
equal to the sum it would have received if no deduction or
withholding had been made;

(b) such Borrower shall make such deductions or withholdings; and

(c) such Borrower shall pay the full amount deducted or withheld to
the relevant taxation or other authority in accordance with
applicable Law.

(2) Pay Taxes. The Borrower shall pay all Taxes which arise from any
payment made hereunder or under any other Credit Facility Document
or from the execution, delivery or registration of, or otherwise
with respect to, this agreement or such other Credit Facility
Document.

(3) Indemnity. The Borrower shall indemnify and save harmless each
Lender for the full amount of Taxes (including any Taxes imposed by
any jurisdiction on amounts payable under this section) paid by
such Lender and any liability (including penalties, interest and
expense) arising therefrom or with respect thereto, whether or not
such Taxes were correctly or legally asserted. Payment under this
indemnification shall be made within 30 days from the date the
Lender makes written demand therefor. A certificate as to the
amount of such Taxes submitted by the Lender to the Borrower (copy
to the Administrative Agent) shall be conclusive evidence, absent
demonstrated error, of the amount due from the Borrower to such
Lender.
76
- 70 -

(4) Survival. Without prejudice to the survival of any other agreement
or obligation of the Borrower hereunder or under any other Credit
Facility Document, the obligations of the Borrower under this
section 11.6 shall survive the payment and performance of the
Obligations.

(5) Lenders. The Lenders shall endeavour to limit the incidence of any
additional amounts payable under this section 11.6, and the
Borrower shall thereafter not be obligated to pay any such amounts
should the cause of same be rescinded, removed, repealed or
withdrawn.

ARTICLE 12

Default shall have occurred as a result thereof unless and until

earlier of (i) written notice thereof given to the Borrower by the
Administrative Agent, and (ii) such time as such person is aware of
same.

12.2 EFFECT.

(1) General. Upon the occurrence and continuance of an Event of

Agent:

(a) shall, at the request of Majority Lenders, by notice to the
Borrower cancel all obligations of the Lenders in respect of
the Commitments (whereupon no further Accommodations may be
made and any Notice given with respect to an Accommodation
occurring on or after the date of such notice or request shall
cease to have effect); and

(b) shall, at the request of Majority Lenders, by notice to the
Borrower declare the Obligations to be forthwith due and
payable, without presentment, demand, protest or further notice
of any kind, all of which are hereby expressly waived by the
Borrower.

(2) Specific Defaults. If any Event of Default specified in section
12.1(6) or 12.1(7) shall occur, then all obligations of the Lenders
in respect of the Commitments shall be automatically cancelled and
the Obligations shall be forthwith due and payable, all as if the
request and notice specified in each of sections 12.2(1)(a) and
12.2(1)(b) had been received and given by the Administrative Agent.

(3) Enforcement. Upon the occurrence of an Event of Default and
acceleration of the Obligations, the Administrative Agent may, and

cumulative and are in addition to and not in substitution for any
other rights or remedies provided by Law; provided that nothing
herein contained shall permit any Lender to take any steps which,
pursuant to this agreement, may
80
- 74 -

only be undertaken by or with the consent of all Lenders or the
Majority Lenders. Nothing contained herein or in any Security now
or hereafter held by the Administrative Agent, with respect to the
Collateral or any part thereof, nor any act or omission of the
Administrative Agent or any Lender with respect to such Security,
shall in any way prejudice or affect the rights, remedies and
powers of the Administrative Agent or the Lenders with respect to
any other such Security.

12.3 RIGHT OF SET-OFF. Following the occurrence of an Event of Default and a
declaration under section 12.2(1)(b) or the Obligations becoming due and
payable under section 12.2(2), each Lender is hereby authorized by the
Borrower at any time and from time to time to the fullest extent permitted
by Law to set off and apply any and all deposits (general or special, time
or demand, provisional or final) at any time held and other Debt at any
time owing to or for the credit or the account of the Borrower against any
and all of the Obligations of the Borrower then due and payable hereunder
and unpaid, and without limitation the Administrative Agent may debit any
account of the Borrower for any such Obligations, whether owed to the
Administrative Agent in its capacity as Administrative Agent or Lender or
owed to other Lenders. Each Lender shall promptly notify the Borrower and
each other Lender after any such set-off and application made by such
Lender; provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of the Lenders under
this section 12.3 are, as between themselves, subject to section 14.1, and
are in addition to all other rights and remedies (including other rights
of set-off) which the Lenders may have.

12.4 CURRENCY CONVERSION AFTER ACCELERATION. At any time following the
occurrence of an Event of Default and the acceleration of the Obligations,
each Lender shall be entitled to convert, with two Business Days' prior
notice to the Borrower, its unpaid and outstanding US Dollar Advances or
any of them to Prime Rate Advances. Any such conversion shall be
calculated so that the resulting Prime Rate Advances shall be the
Equivalent Amount in Cdn. Dollars on the date of conversion of the amount
of US Dollars so converted. Any accrued and unpaid interest denominated
in US Dollars at the time of any such conversion shall be similarly
converted to Cdn. Dollars, and such Prime Rate Advances and accrued and
unpaid interest thereon shall thereafter bear interest in accordance with
Article 3.

ARTICLE 13
THE ADMINISTRATIVE AGENT AND THE LENDERS

13.1 AUTHORIZATION AND ACTION. Each Lender hereby appoints and authorizes the
Administrative Agent to take such action as Administrative Agent on its
behalf and to exercise such powers under this agreement and the other
Credit Facility Documents as are delegated to the Administrative Agent by
the terms hereof and thereof, together with such powers as are reasonably
incidental thereto. As to any matters not expressly provided for by this
agreement or such other Credit Facility Documents, the
81
- 75 -

Administrative Agent shall not be required to exercise any discretion or
take any action, but shall be required to act or to refrain from acting
(and shall be fully indemnified and protected in so acting or refraining
from acting) upon the instructions of the Majority Lenders and such
instructions shall be binding upon all Lenders; provided that the
Administrative Agent shall not be required to take any action which
exposes it to personal liability or which is contrary to this agreement or
such other Credit Facility Documents or applicable Law.

13.2 DUTIES AND OBLIGATIONS. The duties and obligations of the Administrative
Agent hereunder shall be mechanical and administrative in nature, and
Administrative Agent shall not have by reason of this agreement or any
other Credit Facility Document any fiduciary relationship or duty with or
to any Lender.

Neither the Administrative Agent nor any of its directors, officers,
agents or employees shall be liable to any Lender for any action taken or
omitted to be taken by it or them under or in connection with this
agreement or any other Credit Facility Document except for its or their
own gross negligence or wilful misconduct. Without limiting the
generality of the foregoing, the Administrative Agent:

(1) may treat any Lender as the payee of amounts attributable to such
Lender's Commitment unless and until the Administrative Agent
receives written notice of the assignment thereof signed by such
Lender and the Administrative Agent receives the written agreement
of the assignee that such assignee is bound hereby as if it had
been an original Lender party hereto, in each case in form
satisfactory to the Administrative Agent and otherwise in
accordance with section 14.8;

(2) may consult with legal counsel (including counsel for the
Borrower), independent public accountants and other experts
selected by it and shall not be liable to the Lenders for any
action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts;

(3) shall incur no liability under or in respect of this agreement or
any other Credit Facility Document by acting upon any notice,
consent, certificate or other instrument or writing (which may be
by telegram, cable, facsimile or similar means of recorded
communication) believed by it to be genuine and signed or sent by
the proper party or parties or by acting upon any representation or
warranty of the Borrower made or deemed to be made hereunder or
thereunder;

(4) may assume that no Default or Event of Default has occurred and is
continuing unless it has actual knowledge to the contrary; and
82
- 76 -

(5) may rely as to any matters of fact which might reasonably be
expected to be within the knowledge of any person upon a
certificate signed by or on behalf of such person.

Further, the Administrative Agent:

(6) does not make any warranty or representation to any Lender and
shall not be responsible to any Lender for the accuracy or
completeness of the documents, information or financial data made
available to the Lenders in connection with the negotiation of this
agreement, or for any statements, warranties or representations
(whether written or oral) made in or in connection with this
agreement or any other Credit Facility Document;

(7) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or
conditions of this agreement or any other Credit Facility Document
on the part of any MDA Party or any other person or to inspect any
Project Assets (including books and records); or

(8) shall not be responsible to any Lender for the due execution,
legality, validity, enforceability, genuineness, sufficiency or
value of this agreement or any other Credit Facility Document.

The Administrative Agent shall promptly distribute to the Lenders copies
of all material received from the Borrower in compliance with the
Borrower's reporting obligations hereunder.

13.3 ADMINISTRATIVE AGENT AND AFFILIATES. With respect to its Commitment and
Accommodations made and to be made by it, the Administrative Agent, which
is also a Lender, shall have the same rights and powers under this
agreement and every other Credit Facility Document as any other Lender and
may exercise the same as though it were not an Administrative Agent; and
the terms "Lender" and "Lenders" shall, unless otherwise expressly
indicated, include the Administrative Agent in its capacity as Lender.
Each Lender (including the Administrative Agent) and its affiliates may
accept deposits from, lend money to and generally engage in any kind of
business with the Borrower and its affiliates, or any corporation or other
entity owned or controlled by such persons, and any person which may do
business with such persons, all as if it were not a party hereto and
without any duty to account therefor to any Lender; provided that nothing
in this section 13.3 shall affect in any manner whatsoever any covenant or
other obligation on the part of the Borrower or any other person to be
observed or performed under this agreement or any other Credit Facility
Document.

13.4 LENDER CREDIT DECISION. It is understood and agreed by each Lender that
it has itself been, and will continue to be, solely responsible for making
its own independent appraisal of and investigations into the financial
condition, creditworthiness,
83
- 77 -

condition, affairs, status and nature of the Borrower and its affiliates.
Accordingly, each Lender confirms to the Administrative Agent and each
other Lender that it has not relied, and will not hereafter rely, on the
Administrative Agent or any other Lender:

(1) to check or inquire on its behalf into the adequacy, accuracy or
completeness of any information provided by or on behalf of the
Borrower or any affiliate under or in connection with this
agreement or any other Credit Facility Document or the transactions
herein or therein contemplated (whether or not such information has
been or is hereafter distributed to such Lender by the
Administrative Agent or other Lender), or

(2) to assess or keep under review on its behalf the financial
condition, creditworthiness, condition, affairs, status or nature
of the Borrower or any affiliate.

Each Lender acknowledges that a copy of this agreement has been made
available to it for its review and that it is satisfied with the form and
substance hereof.

13.5 INDEMNIFICATIONS. Each Lender shall indemnify the Administrative Agent,
each affiliate thereof, and each respective director, officer, and
employee of the Administrative Agent and of each such affiliate (to the
extent not reimbursed by the Borrower), rateably with all other Lenders
according to their respective Commitments, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever
which may be imposed on, incurred by, or asserted against the
Administrative Agent or any such affiliate, director, officer or employee
in any way relating to or arising out of this agreement or any other
Credit Facility Document or any action taken or omitted by the
Administrative Agent or any such affiliate, director, officer or employee
under this agreement or any other Credit Facility Document; provided that
no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the gross negligence or wilful
misconduct of an indemnitee. Without limiting the generality of the
foregoing, each Lender agrees to reimburse the Administrative Agent and
each such affiliate, director, officer or employee promptly upon demand
for its share (determined rateably as aforesaid) of any out-of-pocket
expenses (including counsel fees) incurred by the indemnitee in connection
with the preservation of any rights of the Administrative Agent or the
Lenders under, or the enforcement of, or legal advice in respect of rights
or responsibilities under, this agreement or any other Credit Facility
Document, to the extent that the Administrative Agent or such affiliate,
director, officer or employee is not reimbursed for such expenses by the
Borrower.

13.6 SUCCESSOR AGENT. The Administrative Agent may, as hereinafter provided,
resign at any time by giving written notice thereof to the Lenders and the
Borrower and may
84
- 78 -

be removed at any time with cause by the Majority Lenders. Upon any such
resignation or removal, the Lenders, after consultation with the Borrower,
shall have the right to appoint a successor Administrative Agent, which
shall be a Lender. If no successor Administrative Agent shall have been so
appointed by the Lenders and shall have accepted such appointment within
30 days after the retiring Administrative Agent's giving of notice of
resignation or the Lenders' removal of the retiring Administrative Agent,
then the retiring Administrative Agent shall on behalf of the Lenders
forthwith designate one of the Lenders the pro tem successor
Administrative Agent, and such designated Lender shall act as
Administrative Agent hereunder pending the appointment of its successor.
Upon the acceptance of any appointment as Administrative Agent hereunder
by a successor Administrative Agent, such successor Administrative Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from any further duties
and obligations under this agreement. After any retiring Administrative
Agent's resignation or removal hereunder as Administrative Agent, the
provisions of this Article 13 shall enure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under
this agreement.

13.7 SUB-AGENT OR CO-AGENT. At any time or times, in order to comply with any
legal requirement in any province, state or other jurisdiction, or to
facilitate the taking by the Administrative Agent of any action provided
for in any Credit Facility Document, the Administrative Agent may appoint
one or more trust companies, chartered banks or other persons (any of whom
may, but need not be, a Lender) to act either as co-agent or sub-agent,
jointly with the Administrative Agent or as a separate agent or agents on
behalf of the Lenders, with such powers and authorities as the
Administrative Agent deems necessary for the effective operation of the
provisions of any Credit Facility Document. In the discretion of the
Administrative Agent, any instrument or agreement appointing any such
co-agent or sub-agent may include provisions for the protection of such
co-agent or sub-agent similar to but no broader than the provisions of
this Article 13. Upon the appointment of any such co-agent or sub-agent
by the Administrative Agent, all references in this agreement and in all
other Credit Facility Documents to the Administrative Agent shall
thereafter be construed as references to such co-agent or sub-agent to the
extent necessary in order to give effect to its powers, authorities and
obligations.

13.8 ASSIGNMENT OF SECURITY. Upon the resignation or removal of the
Administrative Agent pursuant to section 13.6, the Administrative Agent
shall assign and transfer to the successor Administrative Agent all of its
right, title and interest, as agent, in and to the Credit Facility
Document. The successor Administrative Agent shall ensure that all
required notices, registrations and filings in connection with such
assignment are given or made, as the case may be, and the Borrower shall
reimburse the successor Administrative Agent for and in respect of all of
its reasonable costs and expenses in connection therewith.

ARTICLE 14
MISCELLANEOUS

14.1 SHARING OF PAYMENTS; RECORDS.

(1) Sharing. If:

(a) any Lender shall obtain any payment (whether voluntary,
involuntary, through the exercise of any right of set-off
pursuant to section 12.3 or at law or equity, or otherwise) on
account of any Accommodation made by it (other than Increased
Costs paid to it) in excess of its rateable share of payments
on account of such Accommodation; or

(b) (without regard to outstanding Increased Costs) any Lender
shall at the time of acceleration of the Obligations have
outstanding Obligations which are less than its rateable share
of all outstanding Obligations;

then such Lender shall forthwith purchase from the other Lenders
such participations in the Accommodations made by such other
Lenders as shall be necessary to cause such purchasing Lender to
share the excess payment or be owed the outstanding Obligations
rateably with such other Lenders.

In the case of paragraph (a) of this section 14.1(1), if all or any
portion of such excess payment is thereafter recovered from such
purchasing Lender, such purchase from each other Lender shall be
rescinded and each Lender shall repay to the purchasing Lender the
purchase price to the extent of such recovery together with an
amount equal to such other Lender's rateable share (according to
the proportion that the amount such other Lender's required
repayment bears to the total amount so recovered from the
purchasing Lender) of any interest or other amount paid or payable
by the purchasing Lender in respect of the total amount so
recovered.

Any Lender purchasing a participation from another Lender pursuant
to this section 14.1 may, to the fullest extent permitted by Law,
exercise all its rights of payment (including the right of set-off)
with respect to such participation as fully as if such Lender were
a direct creditor of the Borrower in the amount of such
participation.

(2) Records. The Principal Outstanding under the Credit Facilities,
the unpaid interest accrued thereon, the interest rate or rates
applicable to any unpaid principal amounts, the duration of such
application, the date of acceptance or issue, Face Amount and
maturity of all Bankers' Acceptances and Letters of Credit and the
Commitments shall at all times be ascertained from the records of
the Administrative Agent, which shall be conclusive absent
demonstrated error.
86
- 80 -

14.2 AMENDMENTS, ETC.

(1) Amendments - General. Subject to section 14.2(2), no amendment or
waiver of any provision of this agreement or of any other Credit
Facility Document, nor any consent to any departure by the Borrower
or any affiliate herefrom or therefrom, shall in any event be
effective unless the same shall be in writing and signed by the
Majority Lenders, and then such waiver or consent shall be

telephonic notice believed by it in good faith to be from the
Borrower prior to receipt of a Notice. In the event of conflict
between the Administrative Agent's record of the applicable terms
of any Accommodation and such Notice, the Administrative Agent's
record shall prevail, absent demonstrated error.

14.4 NO WAIVER; REMEDIES. No failure on the part of the Administrative Agent
or any of the Lenders to exercise, and no delay in exercising, any right
under any Credit Facility Document shall operate as a waiver thereof, nor
shall any single or partial exercise of any right under any Credit
Facility Document preclude any other or
89
- 83 -

further exercise thereof or the exercise of any other right. The remedies
herein and therein provided are cumulative and not exclusive of any
remedies provided by Law.

14.5 EXPENSES. The Borrower shall pay to the Administrative Agent, on its own
account and on behalf of the Lenders, all reasonable costs and expenses
(including, without limitation, all legal fees and disbursements on a
solicitor and his own client) incurred:

(i) by the Administrative Agent in connection with this agreement, the
other Credit Facility Documents and the Credit Facilities,
including without limitation:

(A) the negotiation of the term sheet and the negotiation,
preparation, printing, execution, delivery, syndication and
interpretation, both prior and subsequent to the Closing Date,
of this agreement and any other Credit Facility Document (in
this section 14.5, collectively, the "DOCUMENTS");

(B) the performance by the Administrative Agent of its obligations
and duties under any Document;

(D) advice of counsel with respect to the administration of or
other matters relating to the Credit Facility, any Document or
any transaction contemplated thereunder;

(E) the enforcement of any Document or the enforcement or
preservation of rights under and the refinancing, renegotiation
or restructuring (including without limitation negotiation of
any so-called "workout" or similar transaction) of the Credit
Facility under this agreement or any other Document or the
bringing of any action, suit or proceeding with respect to the
enforcement of any Document or any such right or seeking any
remedy which may be available to the Administrative Agent or
the Lenders at law or in equity; and

(F) any amendments, waivers or consents requested by or in respect
of the Borrower or any affiliate pursuant to the provisions
hereof or any other Document;

(ii) by each of the Lenders in connection with:

(A) the enforcement of any Document or the enforcement or
preservation of rights under and the refinancing, renegotiation
or restructuring (including without limitation negotiation of
any so-called "workout" or similar transaction) of the Credit
Facility under this agreement or any
90
- 84 -

other Document or the bringing of any action, suit or
proceeding with respect to the enforcement of any Document or
any such right or seeking any remedy which may be available to
the Lenders at law or in equity; and

(B) any amendments, waivers or consents requested by or in respect
of the Borrower or any affiliate pursuant to the provisions
hereof or any other Document.

In addition, the Borrowers shall pay any present or future stamp,
documentary or other like duties and taxes or any other excise or property
taxes, charges or similar levies which arise from any payment made under
any Credit Facility Document or from the execution, delivery or
registration of, or otherwise in respect to, any Credit Facility Document
and shall indemnify and save the Administrative Agent and the Lenders
harmless from and against any and all liabilities with respect to or
resulting from any delay in paying or omission to pay such duties or
taxes. The obligations of the Borrower under this section 14.5 shall
survive the payment and performance of the Obligations.

14.6 JUDGMENT CURRENCY.

(1) Exchange Rate. If, for the purposes of obtaining judgment in any
court, it is necessary to convert a sum due hereunder to the
Administrative Agent or a Lender in one currency (in this section
14.6, the "ORIGINAL CURRENCY") into another currency (in this
section 14.6, the "JUDGMENT CURRENCY"), the parties agree, to the
fullest extent that they may effectively do so, that the rate of
exchange used shall be that at which in accordance with normal
banking procedures the Administrative Agent or Lender could
purchase the Original Currency with the Judgment Currency on the
Business Day preceding that on which final judgment is paid or
satisfied.

(2) Obligation. The obligations of the Borrower in respect of any sum
due in the Original Currency from it to the Administrative Agent or
a Lender under any Credit Facility Document shall, notwithstanding
any judgment in any Judgment Currency, be discharged only to the
extent that, on the Business Day following receipt by the
Administrative Agent or Lender of any sum adjudged to be so due in
such Judgment Currency, the Administrative Agent or Lender may in
accordance with normal banking procedures purchase the Original
Currency with such Judgment Currency. If the amount of the
Original Currency so purchased is less than the sum originally due
to the Administrative Agent or Lender in the Original Currency, the
Borrower agrees, as a separate obligation and notwithstanding any
such judgment, to indemnify the Administrative Agent or Lender
against such loss and, if the amount of the Original Currency so
purchased exceeds the sum originally due to such Agent
91
- 85 -

or Lender in the Original Currency, the Administrative Agent or
Lender agrees to remit such excess to the Borrower.

14.7 GOVERNING LAW.

(1) Governing Law. This agreement shall be governed by and construed
in accordance with the laws of the Province of British Columbia and
the laws of Canada applicable therein.

(2) Submission to Jurisdiction. Each party hereby irrevocably submits
to the jurisdiction of the courts of British Columbia in any action
or proceeding arising out of or relating to this agreement and
hereby irrevocably agrees that all claims in respect of any such
action or proceeding may be heard and determined in such courts.
Each party hereby irrevocably waives, to the fullest extent it may
effectively do so, the defence of an inconvenient forum to the
maintenance of such action or proceeding. When a name and address
is so indicated opposite a party on the signature pages hereof,
such party hereby irrevocably appoints the person of such name (in
this section 14.7(2), its "PROCESS AGENT") as its agent to receive
on behalf of such party and its property service of copies of the
summons and complaint and any other process which may be served in
any such action or proceeding. Such service may be made by
delivering a copy of such process to the party in care of its
Process Agent at such Process Agent's address so indicated, and
such party hereby irrevocably authorizes and directs its Process
Agent to accept such service on its behalf. As an alternative
method of service, each party also irrevocably consents to the
service of any and all process in any such action or proceeding by
the mailing of copies of such process to it at its address referred
to in section 14.3 or at such other address as it may direct in
accordance with section 14.3. Each party agrees that a final
judgment in any such action or proceeding shall be conclusive and
may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by Law.

(3) Non-Exclusive. Nothing in this section 14.7 shall affect the right
of any party to serve legal process in any other manner permitted
by Law or affect the right of a party to bring any action or
proceeding against another party or its property in the courts of
other jurisdictions.

(4) Trial by Jury. Each of the parties hereto, to the fullest extent
permitted by Law, hereby waives its rights to a trial by jury.
92
- 86 -

14.8 SUCCESSORS AND ASSIGNS.

(1) Effectiveness. This agreement shall become effective when it shall
have been executed by the Borrower, the Administrative Agent and
each Lender and thereafter shall be binding upon and enure to the
benefit of each such person, its successors and permitted assigns.

(2) Borrower not to Assign. The Borrower shall not have the right to
assign its rights or obligations hereunder or any interest herein
(other than in compliance with section 10.2(3), without the prior
consent of all the Lenders, which consent may be arbitrarily
withheld.

(3) Participations; Assignments. A Lender may:

(a) grant participations in all or any part of a Credit Facility to
one or more persons (each a "PARTICIPANT"); or

(b) assign all or any part (in a minimum amount of $5 million) of
its interest in all (but no less than all) of the Credit
Facilities to one or more persons (each an "ASSIGNEE") and, to
the extent of any such assignment (unless otherwise stated
therein), the assignee shall have the same rights and benefits
hereunder and under the other Credit Facility Documents as it
would have if it were a Lender hereunder;

provided that:
(c) no such Participant or Assignee shall be entitled to receive
any greater payment, on a cumulative basis, than the relevant
Lender would have been entitled to receive;

(d) unless an Event of Default shall have occurred and be
continuing, the consent of the Borrower to an assignment under
section 14.8(3)(b) shall be required (which consents shall not
be unreasonably withheld), and the Borrower shall have the
right to request a period of 30 days within which to seek an
alternate assignee;

(e) no Lender shall have a Commitment below $10 million; and

(f) no such Participant or Assignee shall be a non-resident of
Canada for Canadian withholding tax purposes.

(4) Financial Information. A Lender may deliver a copy of any
financial statement or any other information relating to the
business, assets or condition (financial or otherwise) of the
Borrower or its affiliates which may be furnished to it under this
agreement or otherwise to any Participant or Assignee or any
prospective Participant or Assignee to the extent reasonably
required by such
93
- 87 -

Participant or Assignee in connection with its interest or the
proposed acquisition of an interest in a Credit Facility, subject
to compliance by such Lender with section 14.10.

(5) Lender to Act. Prior to the occurrence of a Default or an Event of
Default, the relevant Lender shall act on behalf of all of its
Participants in all dealings with the Borrower in respect of the
relevant Credit Facility.

(6) Assumption. In order to effect an assignment contemplated by
section 14.8(3)(b), the relevant Lender (i) shall deliver to the
Borrower (at such Lender's cost but exclusive of the fees of the
Borrower's counsel) an agreement by which the Assignee assumes the
obligations and agrees to be bound by all the terms and conditions
of this agreement, all as if such Assignee had been an original
party hereto and (ii) shall pay an administration fee of $3,500 to
the Administrative Agent. Upon any such assignment and such
assumption of the obligations of such Lender by such Assignee, such
Lender and the Borrower shall be mutually released from their
respective obligations hereunder to the extent of such assignment
and assumption and shall thenceforth have no liability or
obligations to each other to such extent, except in respect of
actions taken or matters which have arisen prior to such

POWER OF ATTORNEY

WHEREAS ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ and Associates Ltd. (the "BORROWER")
wishes to facilitate the acceptance of Bankers' Acceptances pursuant to
the terms of the credit agreement dated as of March 31, 2000 among the
Borrower, Royal Bank of Canada as Administrative Agent, and the Lenders
named therein, to which NAME OF BANK is a party (as amended, supplemented
and restated from time to time, the "CREDIT AGREEMENT").

NOW THEREFORE, the Borrower hereby appoints NAME OF BANK
(hereinafter called the "BANK"), acting by an authorized signing officer
of the Bank, the attorney of the Borrower:

(a) to sign for and on behalf and in the name of the Borrower as
drawer, and if applicable, as endorser, drafts in the Bank's
standard form ("DRAFTS") drawn on the Bank payable to the order
of CDS & Co. (or other nominee name of The Canadian Depository
for Securities Limited) or payable to the order of the Bank;
and

(b) to fill in the amount, date and maturity date of such Drafts;

provided that such acts in each case are to be undertaken by the Bank in
accordance with instructions given to the Bank by the Borrower as
provided in this power of attorney.

Instructions to the Bank relating to the execution, completion,
endorsement, discount and/or delivery by the Bank on behalf of the
Borrower of Drafts which the Borrower wishes to submit to the Bank for
acceptance by the Bank shall be communicated by the Administrative Agent
and/or the Borrower to the Bank in writing to the Attorney at the Bank's
Lending Branch following delivery by the Borrower of an Accommodation
Request pursuant to section 4.2(1) of the Credit Agreement and shall
specify the following information:

(a) reference to this power of attorney;

(b) a Canadian Dollar amount, which shall be the aggregate face
amount of the Drafts to be accepted by the Bank in respect of a
particular Drawing; and

(c) a specified period of time in accordance with section 4.3 of
the Credit Agreement, which shall be the number of days after
the date of such Drafts that such Drafts are to be payable, and
the dates of issues and maturity of such Drafts.

The communication in writing by the Borrower to the Bank of the
instructions referred to above shall constitute (a) the authorization and
instruction of the Borrower to the Bank to complete and endorse Drafts in
accordance with such information as set out above, and (b) the request of
the Borrower to the Bank to accept such Drafts and deliver the same
against payment as set out in the instructions. The Borrower
acknowledges that the Bank shall not be

103

obligated to accept any such Drafts except in accordance with the
provisions of the Credit Agreement.

The Bank shall be and it is hereby authorized to act on behalf of
the Borrower upon and in compliance with instructions communicated to the
Bank as provided herein if the Bank reasonably believes them to be
genuine. If the Bank accepts Drafts pursuant to any such instructions,
the Bank shall confirm particulars of such instructions and advise the
Borrower that the Bank has complied therewith by notice in writing
addressed to the Borrower in accordance with the Credit Agreement. The
Bank's actions confirmed and advised to the Borrower by such notice shall
be conclusively deemed to have been in accordance with the instructions
of the Borrower unless the Borrower notifies the Bank to the contrary in
writing not later than the Business Day next following such deemed
receipt by the Borrower.

The Borrower agrees to indemnify the Bank and its directors,
officers, employees, affiliates and agents and to hold it and them
harmless from and against any loss, liability, expense or claim of any
kind or nature whatsoever incurred by any of them as a result of any
action or inaction in any way relating to or arising out of this power of
attorney or the act contemplated hereby; provided that this indemnity
shall not apply to any such loss, liability, expense or claim which
results from the negligence or wilful misconduct of the Bank or any of
its directors, officers, employees, affiliates or agents or for the Bank
or any of its directors, officers, employees, affiliates or agents
failing to use the same standard of care in the custody of such Drafts as
the Bank uses in the custody of its own property of a similar nature.

This power of attorney may be revoked at any time upon not less
than five (5) Business Days' written notice served upon the Bank at its
Lending Branch; provided that (i) it may be replaced with another power
of attorney forthwith in accordance with the requirements of section 4.8
of the Credit Agreement; and (ii) no such revocation shall reduce, limit
or otherwise affect the obligations of the Borrower in respect of any
Draft executed, completed, endorsed, discounted and/or delivered in
accordance herewith prior to the time at which such revocation becomes
effective.

This power of attorney is in addition to and not in substitution
for any agreement to which the Bank and the Borrower are parties.

This power of attorney shall be governed in all respects by the
laws of the Province of British Columbia and the laws of Canada
applicable therein and each of the Borrower and the Bank hereby
irrevocably attorns to the non-exclusive jurisdiction of the courts of
such jurisdiction in respect to all matters arising out of this power of
attorney.

In the event of a conflict between the provisions of this Power of
Attorney and the Credit Agreement, the Credit Agreement shall prevail.
Capitalized terms used and not defined herein shall have the meanings
