and Base Rate Advances shall be Continued as Prime Rate Advances or Base Rate
Advances, as applicable, after the Revolving Commitment Termination Date, unless
the Borrower shall have elected otherwise by delivery of a Notice of
Continuation. In accordance with Section 2.08, the Borrower may elect to
Continue Borrowings as Borrowings of the same or a different Type or, in the
case of a Eurodollar Rate Advance or B/A Advance, may elect Interest Periods or
Contract Periods therefor; provided that the Borrower shall not be entitled to
elect to Continue any Borrowings if the Interest Period or Contract Period
requested with respect thereto would end after the Final Maturity Date. After

                  (i) in the case of a proposed Borrowing comprised of Prime
         Rate Advances or Base Rate Advances on the day of notice, provided that

         time) on the third Business Day prior to the date of such proposed
         Borrowing; and

         Business Day prior to the date of such proposed Borrowing or, if such

not later than 10:00 a.m. (Calgary local time) on the date of the proposed
Borrowing), the Administrative Agent shall advise each Lender of the details
thereof and of the amount of such Lender's Advance to be made as part of the
requested Borrowing. Each Lender shall, before 11:00 a.m. (Calgary local time)
on the date of such Borrowing, make available for the account of its Applicable
Lending Office to the Administrative Agent in care of its Payment Office, or at

portion of such Borrowing. Immediately after the Administrative Agent's receipt

Article 3, but no later than 12:00 noon (Calgary local time) on the same date
the Administrative Agent will make such funds available to the Borrower at the
Payment Office of the Administrative Agent, or at any account of the Borrower
maintained by the Administrative Agent (or any successor Administrative Agent)
designated by the Borrower and agreed to by the Administrative Agent (or such
successor Administrative Agent), in same day funds.

                  (b) If no election as to the Type or duration of Advance is

denominated in Cdn. Dollars) or a Base Rate Advance (if denominated in U.S.
Dollars). If no currency is specified, the Advance shall be denominated in Cdn.
Dollars.

                  (c) Each Notice of Borrowing shall be irrevocable and binding
on the Borrower. In the case of any Borrowing which the related Notice of
Borrowing specified is to be comprised of Eurodollar Rate Advances, if such
Advances are not made as a result of any failure to fulfill on or before the
date specified for such Borrowing the applicable conditions set forth in Article
3, the Borrower shall indemnify each Lender against any loss, cost or expense
incurred

                                       20



by such Lender as a result of such failure, including any loss, cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund the Advance to be made by such Lender as part of
such Borrowing.

                  (d) 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 ratable portion of such
Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such Borrowing in
accordance with subsections (a) and (c) of this Section 2.02 and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower on such date a corresponding amount. If and to the extent such
Lender shall not have so made such ratable portion available to the
Administrative Agent, such Lender and the Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent, at the Prime Rate for such day. If such Lender shall repay to the
Administrative Agent such corresponding amount, such amount so repaid shall
constitute such Lender's Advance to the Borrower as part of such Borrowing for
purposes of this Agreement.

                  (e) The failure of any Lender to make the Advance to be made
by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Advance on the date of such Borrowing,
but no Lender shall be responsible for the failure of any other Lender to make
the Advance to be made by such other Lender on the date of any Borrowing.

                  SECTION 2.03. FEES. (a) FACILITY FEE. The Borrower agrees to
pay to the Administrative Agent for the account of each Lender a facility fee on
the average daily amount of such Lender's Commitment, whether or not used or
deemed used, from the Effective Date in the case of each Initial Lender and from
the effective date specified in the Assignment and Acceptance or Commitment
Increase Agreement pursuant to which it became a Lender in the case of each
other Lender, in each case until the Termination Date, payable quarterly in
arrears on the last day of each March, June, September and December during the
term of such Lender's Commitment and on the Termination Date, at a rate per
annum equal to the Facility Fee Percentage in effect from time to time.

                  (b) UTILIZATION FEE. The Borrower agrees to pay to the
Administrative Agent for the account of each Lender (i) for any Utilization Fee
Period, if during such Utilization Fee Period the Average Aggregate Facility
Advances were greater than 25% and less than or equal to 50% of the Average
Aggregate Facility Commitments, a utilization fee of 0.125% per annum on the
average daily amount of such Lender's Advances during such Utilization Fee
Period; and (ii) for any Utilization Fee Period, if during such Utilization Fee
Period the Average Aggregate Facility Advances were greater than 50% of the
Average Aggregate Facility Commitments, a utilization fee of 0.25% per annum on
the average daily amount of such Lender's Advances during such Utilization Fee
Period. If a utilization fee is owing in respect of any Utilization Fee Period,
such fee shall be payable on the last day of such Utilization Fee Period.



                                       21


                  (c) AGENCY FEE. The Borrower agrees to pay to the
Administrative Agent, for its own account, such agency fees as may be separately
agreed to in writing by the Borrower and the Administrative Agent, such fees to
be in the amounts and payable on the dates as may be so agreed to.

                  SECTION 2.04. REDUCTION OF THE COMMITMENTS. The Borrower shall
have the right, upon at least three Business Days' written notice to the
Administrative Agent, to terminate in whole or reduce ratably in part the unused
portions of the Commitments of the Lenders (being the amount by which such
Commitments exceed the aggregate outstanding principal amount of all Advances),
provided that each partial reduction shall be in the aggregate amount of
Cdn.$10,000,000 or any whole multiple of Cdn.$1,000,000 in excess thereof.

                  SECTION 2.05. REPAYMENT OF ADVANCES. (a) (a) The Borrower
shall repay to each Lender on the Final Maturity Date the aggregate principal
amount of the Advances, together with accrued interest thereon, then owing to
such Lender.

                  (b) Subject to Section 2.05(c), after the Revolving Commitment
Termination Date, the Borrower shall repay the principal amount of the Advances
in equal semi-annual installments, each in an amount equal to two and one-half
percent (2.5%) of the aggregate outstanding principal amount of the Advances on
the Revolving Commitment Termination Date. Such installments shall be due and
payable on each June 30 and December 31 of each year, the first such installment
being due and payable on the first December 31 occurring after the Revolving
Commitment Termination Date, with the final installment due and payable on the
Final Maturity Date in an amount equal to the aggregate unpaid principal amount
of such Advances outstanding on the Final Maturity Date.

                  (c) Subject to Article 6, but notwithstanding any other
provision of this Agreement, the Borrower shall not be required to repay more
than 25% of the principal amount (as defined in the Income Tax Act) of the
Advances made to it prior to five years and one day after the Revolving
Commitment Termination Date, including, but not limited to payments under
Section 2.05(b) and Section 2.10(b).

                  (d) The Borrower shall provide written notice to the
Administrative Agent substantially in the form of Exhibit C hereto of any
repayments pursuant to this Section 2.05 at least 2 Business Days prior to such
repayment.

                  SECTION 2.06. INTEREST ON ADVANCES. (a) ORDINARY INTEREST.
The Borrower shall pay interest on the unpaid principal amount of each Advance
owing to each Lender from the date of such Advance until such principal amount
is due (whether at stated maturity, by acceleration or otherwise), at the
following rates:

                  (i) PRIME RATE ADVANCES. During such periods as such Advance
         is a Prime Rate Advance, a rate per annum equal at all times to the
         Prime Rate in effect from time to time plus, following the Revolving
         Commitment Termination Date, as additional interest in lieu of the
         facility fee, the Facility Fee Percentage in effect from time to time,
         payable quarterly in arrears on the last day of each March, June,
         September and December during


                                       22


         such periods and on the date such Prime Rate Advance shall be Continued
         or due (whether at stated maturity, by acceleration or otherwise).

                  (ii) BASE RATE ADVANCES. During such periods as such Advance
         is a Base Rate Advance, a rate per annum equal at all times to the Base
         Rate in effect from time to time plus, following the Revolving
         Commitment Termination Date, as additional interest in lieu of the
         facility fee, the Facility Fee Percentage in effect from time to time,
         payable quarterly in arrears on the last day of each March, June,
         September and December during such periods and on the date such Base
         Rate Advance shall be Continued or due (whether at stated maturity, by

                  (iii) EURODOLLAR RATE ADVANCES. During such periods as such
         Advance is (x) a Cdn. Dollar Eurodollar Rate Advance, a rate per annum
         equal at all times during each Interest Period for such Advance to the
         sum of the Cdn. Dollar Eurodollar Rate for such Interest Period plus
         the Eurodollar Rate Margin in effect from time to time plus, following
         the Revolving Commitment Termination Date, as additional interest in
         lieu of the facility fee, the Facility Fee Percentage in effect from
         time to time, payable on the last day of each such Interest Period and,
         if any such Interest Period has a duration of more than three months,
         on each day which occurs during such Interest Period every three months
         from the first day of such Interest Period and, if such Advance is
         Continued as a Prime Rate Advance on any date other than the last day
         of any Interest Period for such Advance, on the date of such
         Continuation or, if later, the Business Day on which the Borrower shall
         have received at least one Business Day's prior notice from the
         Administrative Agent or the applicable Lender of the amount of unpaid
         interest accrued on such Advance to the date of such Continuation and
         (y) a U.S. Dollar Eurodollar Rate Advance, a rate per annum equal at
         all times during each Interest Period for such Advance to the sum of
         the U.S. Dollar Eurodollar Rate for such Interest Period plus the
         Eurodollar Rate Margin in effect from time to time plus, following the
         Revolving Commitment Termination Date, as additional interest in lieu
         of the facility fee, the Facility Fee Percentage in effect from time to
         time, payable on the last day of each such Interest Period and, if any
         such Interest Period has a duration of more than three months, on each
         day which occurs during such Interest Period every three months from
         the first day of such Interest Period and, if such Advance is Continued
         as a Base Rate Advance on any date other than the last day of any
         Interest Period for such Advance, on the date of such Continuation or,
         if later, the Business Day on which the Borrower shall have received at
         least one Business Day's prior notice from the Administrative Agent or
         the applicable Lender of the amount of unpaid interest accrued on such
         Advance to the date of such Continuation.

                  (iv) B/A ADVANCES. Each Advance comprised of Bankers'
         Acceptances shall be subject to an Acceptance Fee, payable by the
         Borrower on the date of acceptance of the relevant B/A and computed as
         set forth in the definition of "Acceptance Fee" in Section 1.01 plus,
         following the Revolving Commitment Termination Date, as an additional
         acceptance fee in lieu of the facility fee, the Facility Fee Percentage
         in effect from time to time, payable quarterly in arrears on the last
         day of each March, June, September and December during such periods and
         on the date such B/A Advance shall be Continued or due (whether at
         stated maturity, by acceleration or otherwise).

                                       23



                  (v) ADDITIONAL INTEREST. In addition to amounts payable under
         clause (i), (ii), (iii) or (iv) above in respect of any Advance
         following the Revolving Commitment Termination Date, the Borrower shall
         pay to each Lender hereunder as additional interest an amount in lieu
         of the utilization fee equal to 0.25% per annum on the average daily
         amount of such Lender's Term Advances during any period (each such
         period, an "ADDITIONAL INTEREST PERIOD") during the term of this
         Agreement commencing on the Termination Date or on a subsequent January
         1, April 1, July 1 or October 1 and ending in each case on the earliest
         to occur of the next succeeding March 31, June 30, September 30 or
         December 31 and the Final Maturity Date (or, if any Term Advances
         remain outstanding after the Final Maturity Date, such later date on
         which all such Advances are repaid in full). Additional interest owing
         in respect of any Additional Interest Period shall be payable on the
         last day of such Additional Interest Period; provided that additional
         interest owing after the Final Maturity Date shall be payable on
         demand.

                  (b) DEFAULT INTEREST. The Borrower shall pay interest on the
unpaid principal amount of each Advance that is not paid when due (whether at
stated maturity, by acceleration or otherwise) 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 (i) from such due date to the last day of the then
existing Interest Period therefor, in the case of each Eurodollar Rate Advance,
to 1% per annum above the interest rate per annum required to be paid on such
Advance immediately prior to the date on which such amount became due and (ii)
from and after the last day of the then existing Interest Period therefor, in
the case of each Eurodollar Rate Advance, and at all times in the case of each
Prime Rate Advance and each Base Rate Advance, to 1% per annum above the Prime
Rate or Base Rate, as applicable, in effect from time to time.

                  (c) INTEREST ACT CANADA. For the purposes of the Interest Act
(Canada) and disclosure thereunder, whenever any interest or fee to be paid
hereunder or in connection herewith is to be calculated on the basis of any
period of time that is less than a calendar year, the yearly rate of interest to
which the rate used in such calculation is equivalent is the rate so used
multiplied by the actual number of days in the calendar year in which the same
is to be ascertained and divided by 360 or 365, as applicable. The rates of
interest under this Agreement are nominal rates, and not effective rates or
yields. The principle of deemed reinvestment of interest does not apply to any
interest calculation under this Agreement.

                  (d) NO CRIMINAL RATE. If any provision of this Agreement would
oblige the Borrower to make any payment of interest or other amount payable to
any Lender in an amount or calculated at a rate which would be prohibited by law
or would result in a receipt by that Lender of "interest" at a "criminal rate"
(as such terms are construed under the Criminal Code (Canada)), then,
notwithstanding such provision, such amount or rate shall be deemed to have been
adjusted with retroactive effect to the maximum amount or rate of interest, as
the case may be, as would not be so prohibited by law or so result in a receipt
by that Lender of "interest" at a "criminal rate", such adjustment to be
effected, to the extent necessary (but only to the extent necessary), as
follows:



                                       24


                  (i) first, by reducing the amount or rate of interest or the
         amount or rate of any Acceptance Fee required to be paid to the
         affected Lender under Section 2.06(a)(iv); and

                  (ii) thereafter, by reducing any fees, commissions, premiums
         and other amounts required to be paid to the affected Lender which
         would constitute interest for purposes of Section 347 of the Criminal
         Code (Canada).

                  SECTION 2.07. [INTENTIONALLY OMITTED]

                  SECTION 2.08. RATE DETERMINATION. (a) All interest hereunder
shall be payable for the actual number of days elapsed (including the first day
but excluding the last day). Any Advance that is repaid on the same day on which
it is made shall bear interest for one day unless such repayment and notice
thereof are received by 12:00 noon, Toronto, Ontario time, on such day. The
applicable Prime Rate, Base Rate, Eurodollar Rate or Discount Rate shall be
determined by the Administrative Agent, and such determination shall be
conclusive absent manifest error.

                  (b) Each Reference Bank agrees to furnish to the
Administrative Agent timely information for the purpose of determining each
Eurodollar Rate. If any one or more of the Reference Banks shall not furnish
such timely information to the Administrative Agent for the purpose of
determining any such interest rate, the Administrative Agent shall determine
such interest rate on the basis of timely information furnished by the remaining
Reference Banks. Each Schedule II/III Reference Bank agrees to furnish to the
Administrative Agent timely information for the purpose of determining each
Discount Rate. If any one or more of the Schedule II/III Reference Banks shall
not furnish such timely information to the Administrative Agent for the purpose
of determining such Discount Rate, the Administrative Agent shall determine such
Discount Rate on the basis of timely information furnished by the remaining
Schedule II/III Reference Banks.

                  (c) The Administrative Agent shall give prompt notice to the
Borrower and the Lenders of the applicable interest rate determined by the
Administrative Agent for purposes of Section 2.06(a)(i), (ii) or (iii), the
applicable rate, if any, furnished by each Reference Bank for the purpose of
determining the applicable interest rate under Section 2.06(a)(iii), and the
applicable Discount Rate, if any, furnished by each Schedule II/III Reference
Bank for the purpose of determining the applicable Discount Rate under Section
2.11(f).

                  (d) If fewer than two Reference Banks furnish timely
information to the Administrative Agent for determining the Eurodollar Rate for
any applicable Advances,

                  (i) the Administrative Agent shall give the Borrower and each
         Lender prompt notice by telephone (confirmed in writing) that the
         interest rate cannot be determined for such applicable Advances,

                  (ii) (x) to the extent such applicable Advances are Cdn.
         Dollar Eurodollar Rate Advances, each such Advance will automatically,
         on the last day of the then existing Interest Period therefor, Continue
         as a Prime Rate Advance (or if such Advance is then a Prime Rate
         Advance, will Continue as a Prime Rate Advance), and (y) to the extent
         such


                                       25


         applicable Advances are U.S. Dollar Eurodollar Rate Advances, each such
         Advance will automatically, on the last day of the then existing
         Interest Period therefor, Continue as a Base Rate Advance (or if such
         Advance is then a Base Rate Advance, will Continue as a Base Rate
         Advance), and

                  (iii) the obligations of the Lenders to make, or to Continue
         Advances as, Cdn. Dollar Eurodollar Rate Advances or U.S. Dollar
         Eurodollar Rate Advances, as the case may be, shall be suspended until
         the Administrative Agent shall notify the Borrower and the Lenders that
         the circumstances causing such suspension no longer exist.

                  (e) If, with respect to any Eurodollar Rate Advances, the
Majority Lenders determine and give notice to the Administrative Agent that as a
result of conditions in or generally affecting the relevant market, the rates of
interest determined on the basis of the Eurodollar Rate for any Interest Period
for such Advances will not adequately reflect the cost to such Majority Lenders
of making, funding or maintaining their respective Eurodollar Rate Advances for
such Interest Period, the Administrative Agent shall forthwith so notify the
Borrower and the Lenders, whereupon:

                  (i) (x) to the extent such Advances are Cdn. Dollar Eurodollar
         Rate Advances, each such Eurodollar Rate Advance will automatically, on
         the last day of the then existing Interest Period therefor, Continue as
         a Prime Rate Advance and (y) to the extent such Advances are U.S.
         Dollar Eurodollar Rate Advances, each such Eurodollar Rate Advance will
         automatically, on the last day of the then existing Interest Period
         therefor, Continue as a Base Rate Advance, and

                  (ii) the obligation of the Lenders to make, or to Continue
         Advances as, Cdn. Dollar Eurodollar Rate Advances or U.S. Dollar
         Eurodollar Rate Advances, as the case may be, shall be suspended until
         the Administrative Agent shall notify the Borrower and the Lenders that
         the circumstances causing such suspension no longer exist.

                  (f) If the Borrower shall fail to select the duration of any
Interest Period for any Eurodollar Rate Advances in accordance with the
provisions contained in the definition of "INTEREST PERIOD" in Section 1.01, the
Administrative Agent will forthwith so notify the Borrower and the Lenders and
(i) to the extent such Advances are Cdn. Dollar Eurodollar Rate Advances, such
Advances will automatically, on the last day of the then existing Interest
Period therefor, Continue as Cdn. Dollar Eurodollar Rate Advances with an
Interest Period of one month and (ii) to the extent such Advances are U.S.
Dollar Eurodollar Rate Advances, such Advances will automatically, on the last
day of the then existing Interest Period therefor, Continue as U.S. Dollar
Eurodollar Rate Advances with an Interest Period of one month. If the Borrower
shall fail to select the duration of any Contract Period for any B/A Advances in
accordance with the provisions contained in the definition of "CONTRACT PERIOD"
in Section 1.01, the Administrative Agent will forthwith so notify the Borrower
and the Lenders and such B/A Advances will be automatically Continued as B/A
Advances with a Contract Period of one month.

                  (g) On the date on which the aggregate unpaid principal amount
of Advances comprising any Borrowing shall be reduced, by payment or prepayment
or otherwise, to less than


                                       26


Cdn.$5,000,000, such Advances shall, (i) if they are (x) Cdn. Dollar Eurodollar
Rate Advances, automatically Continue as Prime Rate Advances and (y) U.S. Dollar
Eurodollar Rate Advances, automatically Continue as Base Rate Advances, and on
and after such date the right of the Borrower to Continue such Advances as
Eurodollar Rate Advances shall terminate; provided, however, that if and so long
as each such Advance shall be, or be elected to be Continued as, Cdn. Dollar
Eurodollar Rate Advances or U.S. Dollar Eurodollar Rate Advances, as applicable,
having the same Interest Period as Eurodollar Rate Advances of the same Type
comprising another Borrowing or other Borrowings, and the aggregate unpaid
principal amount of all such Eurodollar Rate Advances of the same Type shall, or
upon such Continuation will, equal or exceed, with respect to Cdn. Dollar
Eurodollar Rate Advances, Cdn. $10,000,000 or, with respect to U.S. Dollar
Eurodollar Rate Advances, U.S.$10,000,000, the Borrower shall have the right to
Continue all such Advances as Eurodollar Rate Advances of the same Type having
such Interest Period, and (ii) if they are B/A Advances, automatically Continue
as Prime Rate Advances, and on and after such date the right of the Borrower to
Continue such Advances as B/A Advances shall terminate; provided, however, that
if and so long as each such Advance shall be, or be elected to be Continued as,
B/A Advances having the same Contract Period as B/A Advances comprising another
Borrowing or other Borrowings, and the aggregate unpaid principal amount of all
such B/A Advances shall, or upon Continuation will, equal or exceed
Cdn.$10,000,000, the Borrower shall have the right to Continue all such B/A
Advances as B/A Advances having such Contract Period.

                  SECTION 2.09. VOLUNTARY CONTINUATION OF ADVANCES. The Borrower
may on any Business Day, upon notice given to the Administrative Agent, not
later than the time specified in Section 2.02 for the making of an Advance of
the same Type as that of the existing Advances being Continued if such Advance
were being made on the date of the proposed Continuation, and subject to the
provisions of Section 2.08, 2.12 and 2.14, Continue all Advances of one Type
comprising the same Borrowing as Advances of another Type in the same currency;
provided, however, that any Continuation of any Eurodollar Rate Advances as
Prime Rate Advances or Base Rate Advances, as the case may be, made on any day
other than the last day of an Interest Period for such Eurodollar Rate Advances
shall be subject to the provisions of Section 9.04(b), and any Continuation of
any B/A Advances as Prime Rate Advances made on any day other than the last day
of the Contract Period for such B/A Advance shall be subject to the provisions
of Section 2.11. Each such notice of a Continuation (a "Notice of Continuation")
shall, within the restrictions specified above, specify in substantially the
form attached hereto as Exhibit B (i) the date of such Continuation, (ii) the
Advances to be Continued, (iii) if such Continuation is as Eurodollar Rate
Advances, the Type of Eurodollar Rate Advance and the duration of the Interest
Period for each such Eurodollar Rate Advance, and (iv) if such Continuation is
as B/A Advances, the duration of the Contract Period for each such B/A Advance.

                  SECTION 2.10. PREPAYMENTS. (a) The Borrower may prepay the
Revolving Advances or the Term Advances, provided however that the Borrower may
not prepay any Bankers' Acceptances or B/A Loans; provided, however, that the
Borrower may defease any B/A or B/A Loan by depositing with the Administrative
Agent an amount that, together with interest accruing thereon to the end of the
Contract Period or Interest Period (as applicable) therefor, is sufficient to
pay such maturing Bankers' Acceptances or B/A Loans when due. The Borrower may,
upon (i) in the case of Eurodollar Rate Advances, at least three Business Days
notice or (ii) in the case of Prime Rate Advances or Base Rate Advances,
telephonic notice not


                                       27


later than 8:00 a.m. (Calgary local time) on the date of prepayment followed as
promptly as practicable by written notice, to the Administrative Agent which
specifies the proposed date and aggregate principal amount of the prepayment and
the Type of Advances to be prepaid, and if such notice is given the Borrower
shall, prepay the outstanding principal amounts of the Advances comprising the
same Borrowing in whole or ratably in part, together with accrued interest to
the date of such prepayment on the amount prepaid; provided, however, that (x)
each partial prepayment shall be in an aggregate principal amount not less than
Cdn.$5,000,000 or an integral multiple of Cdn.$1,000,000 in excess thereof in
the case of Prime Rate Advances and Cdn. Dollar Eurodollar Rate Advances, and
U.S.$5,000,000 or an integral multiple of U.S.$1,000,000 in excess thereof in
the case of Base Rate Advances and U.S. Dollar Eurodollar Rate Advances, and (y)
in the event of any such prepayment of Eurodollar Rate Advances on any day other
than the last day of an Interest Period for such Eurodollar Rate Advances, the
Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant
to, and to the extent required by, Section 9.04(b); provided, further, however,
that the Borrower will use its best efforts to give notice to the Administrative
Agent of the proposed prepayment of Base Rate Advances on the Business Day prior
to the date of such proposed prepayment.

                  (b) If on any date, after giving effect to all Advances and
all repayments and prepayments to occur on such date, and based on the Exchange
Rate then in effect, the Administrative Agent determines that the aggregate Cdn.
Dollar Equivalent of the outstanding Advances hereunder shall have exceeded for
more than three consecutive Business Days an amount equal to 105% of the total
Commitments of the Lenders under the Agreement, the Administrative Agent shall
notify the Borrower of such occurrence and the Borrower shall on the next
succeeding Business Day prepay Advances in an aggregate amount sufficient to
eliminate such excess.

                  SECTION 2.11. BANKERS' ACCEPTANCES. (a) Subject to the terms
and conditions of this Agreement, the Borrower may request a Borrowing by
presenting drafts for acceptance and, if applicable, purchase, as B/As by the
Lenders.

                  (b) No Contract Period with respect to a B/A to be accepted
and, if applicable, purchased, as a Revolving Advance shall extend beyond the
Revolving Commitment Termination Date and no Contract Period with respect to a
B/A to be accepted and, if applicable, purchased, as a Term Advance shall extend
beyond the Final Maturity Date.

                  (c) To facilitate availment of B/A Advances, the Borrower
hereby appoints each Lender as its attorney to sign and endorse on its behalf
(in accordance with a Notice of Borrowing or Notice of Continuation relating to
a B/A Advance), in handwriting or by facsimile or mechanical signature as and
when deemed necessary by such Lender, blank forms of B/As in the form requested
by such Lender. In this respect, it is each Lender's responsibility to maintain
an adequate supply of blank forms of B/As for acceptance under this Agreement.
The Borrower recognizes and agrees that all B/As signed and/or endorsed by a
Lender on behalf of the Borrower shall bind the Borrower as fully and
effectually as if signed in the handwriting of and duly issued by the proper
signing officers of the Borrower. Each Lender is hereby authorized (in
accordance with a Notice of Borrowing or Notice of Continuation relating to a
B/A Advance) to issue such B/As endorsed in blank in such face amounts as may be
determined by such Lender; provided that the aggregate amount thereof is equal
to the aggregate amount of B/As required to


                                       28


be accepted and purchased by such Lender. No Lender shall be liable for any
damage, loss or other claim arising by reason of any loss or improper use of any
such instrument except the gross negligence or wilful misconduct of the Lender
or its officers, employees, agents or representatives. Each Lender shall
maintain a record with respect to B/As (i) received by it in blank hereunder,
(ii) voided by it for any reason, (iii) accepted and purchased by it hereunder,
and (iv) canceled at their respective maturities. On request by or on behalf of
the Borrower, a Lender shall cancel all forms of B/As which have been pre-signed
or pre-endorsed on behalf of the Borrower and that are held by such Lender and
are not required to be issued in accordance with the Borrower's irrevocable
notice. Alternatively, the Borrower agrees that, at the request of the
Administrative Agent, the Borrower shall deliver to the Administrative Agent a
"depository note" which complies with the requirements of the Depository Bills
and Notes Act (Canada), and consents to the deposit of any such depository note
in the book-based debt clearance system maintained by the Canadian Depository
for Securities.

                  (d) Drafts of the Borrower to be accepted as B/As hereunder
shall be signed as set forth in this Section 2.11. Notwithstanding that any
Person whose signature appears on any B/A may no longer be an authorized
signatory for any Lender or the Borrower at the date of issuance of a B/A, such
signature shall nevertheless be valid and sufficient for all purposes as if such
authority had remained in force at the time of such issuance and any such B/A so
signed shall be binding on the Borrower.

                  (e) Promptly following the receipt of a Notice of Borrowing or
Notice of Continuation specifying a Borrowing or Continuation of a Borrowing by
way of B/As, the Administrative Agent shall so advise the Lenders and shall
advise each Lender of the aggregate face amount of the B/As to be accepted by it
and the applicable Contract Period (which shall be identical for all Lenders).
In the case of Advances comprised of B/A Advances, the aggregate face amount of
the B/As to be accepted by a Lender shall be in a minimum aggregate amount of
Cdn.$100,000 and shall be a whole multiple of Cdn.$100,000, and such face amount
shall be in the Lenders' pro rata portions of such Borrowing, provided that the
Administrative Agent may in its sole discretion increase or reduce any Lender's
portion of such B/A Advance to the nearest Cdn.$100,000 without reducing the
overall Commitments.

                  (f) The Borrower may specify in a Notice of Borrowing or
Notice of Continuation that it desires that any B/As requested by such Notice of
Borrowing or Notice of Continuation be purchased by the Lenders, in which case
the Lenders shall, upon acceptance of a B/A by a Lender, purchase, or arrange
for the purchase of, each B/A from the Borrower at the Discount Rate for such
Lender applicable to such B/A accepted by it and provide to the Administrative
Agent the Discount Proceeds for the account of the Borrower. The Acceptance Fee
payable by the Borrower to a Lender under Section 2.06(iv) in respect of each
B/A accepted by such Lender shall be set off against the Discount Proceeds
payable by such Lender under this Section 2.11.

                  (g) Where the Borrower so specifies in its Notice of Borrowing
or Notice of Continuation, it shall make its own arrangements for the marketing
of B/As, in which case, by subsequent notice to the Administrative Agent, it
shall provide the Administrative Agent, who shall in turn notify each Lender,
with information as to the discount proceeds payable by the purchasers of the
B/As and the party to whom delivery of the B/As by each Lender is to be made





                                       29


against delivery to each Lender of the applicable discount proceeds, but if it
does not do so, the Borrower shall initiate a telephone call to the
Administrative Agent by 9:00 a.m. (Calgary local time) on the date of advance,
and provide such information to the Administrative Agent. Any such telephonic
advice shall be confirmed by a written notice by the Borrower to the
Administrative Agent prior to 2:00 p.m. (Calgary local time) on the same day.

                  (h) Each Lender may at any time and from time to time hold,
sell, rediscount or otherwise dispose of any or all B/As accepted and purchased
by it.

                  (i) If a Lender is not a bank listed on Schedule I, II or III
of the Bank Act (Canada) or if a Lender notifies the Administrative Agent in
writing that it is otherwise unable to accept bankers' acceptances, such Lender
shall give notice to such effect to the Administrative Agent prior to 10:00
a.m., (Calgary local time), on the date of the requested credit extension (which
notice may, if so stated therein, remain in effect with respect to subsequent
requests for extension of credit by way of Bankers' Acceptance until revoked by
notice to the Administrative Agent) and shall make available to the
Administrative Agent, in accordance with Section 2.01 hereof prior to 11:00 a.m.
(Calgary local time), on the date of such requested credit extension, a Canadian
Dollar Eurodollar Rate Advance (a "BA LOAN") in the principal amount equal to
such Lender's Commitment Percentage of the total amount of credit requested to
be extended by way of Bankers' Acceptances. Such BA Loan shall have an Interest
Period equal to the Contract Period of the Bankers' Acceptances for which it is
a substitute and shall bear interest throughout the Interest Period applicable
to such BA Loan at a rate per annum equal to the Canadian Dollar Eurodollar Rate
plus the Eurodollar Rate Margin. Subject to repayment requirements, on the last
day of the relevant Interest Period for such B/A Loan, the Borrower shall be
entitled to Continue each such B/A Loan as another Type of Advance, or to roll
over each such B/A Loan into another B/A Loan, all in accordance with the
applicable provisions of this Agreement.

                  (j) With respect to each B/A Advance, at or before 9:00 a.m.
(Calgary local time) two Business Days before the last day of the Contract
Period of such B/As, the Borrower shall notify the Administrative Agent by
irrevocable telephone notice, followed by a notice of rollover in substantially
the form set forth in Exhibit B hereto on the same day, if the Borrower intends
to issue B/As on such last day of the Contract Period to provide for the payment
of such maturing B/As. If the Borrower fails to notify the Administrative Agent
of its intention to issue B/As on such last day of the Contract Period, the
Borrower shall provide payment to the Administrative Agent on behalf of the
Lenders of an amount equal to the aggregate face amount of such B/As on the last
day of the Contract Period of such B/As. If the Borrower fails to make such
payment, such maturing B/As shall be deemed to have been Continued on the last
day of such Contract Period as a Prime Rate Advance in an amount equal to the
face amount of such B/As.

                  (k) The Borrower waives presentment for payment and any other
defense to payment of any amounts due to a Lender in respect of a B/A accepted
and purchased by it pursuant to this Agreement which might exist solely by
reason of such B/A being held, at the maturity thereof, by such Lender in its
own right, and the Borrower agrees not to claim any days of grace if such
Lender, as holder, sues the Borrower on the B/A for payment of the amount
payable by the Borrower thereunder. On the last day of the Contract Period of a
B/A, or such earlier date as may be required or permitted pursuant to the
provisions of this Agreement, the


                                       30


Borrower shall pay the Lender that has accepted and purchased such B/A the full
face amount of such B/A and, after such payment, the Borrower shall have no
further liability in respect of such B/A and such Lender shall be entitled to
all benefits of, and be responsible for all payments due to third parties under,
such B/A.

                  (l) Except as required by any Lender upon the occurrence of an
Event of Default, no B/A Advance may be repaid by the Borrower prior to the
expiry date of the Contract Period applicable to such B/A Advance.

                  SECTION 2.12. INCREASED COSTS. (a) If, due to either (i) the
introduction after the Effective Date of, or any change after the Effective Date
(including any change by way of imposition or increase of reserve requirements
or assessments) in or in the interpretation of, any law or regulation or (ii)
the compliance with any guideline or request issued or made after the Effective
Date from or by any governmental authority (whether or not having the force of
law), (the occurrence of any of the foregoing events being herein referred to as
a "change in law") in each case above other than with respect to matters covered
by Section 2.13 or 2.16, there shall be any increase in the cost to any Lender
of agreeing to make, fund or maintain, or of making, funding or maintaining
Eurodollar Rate Advances funded in the interbank Eurodollar market, then the
Borrower shall from time to time, upon demand by such Lender (with a copy of
such demand to the Administrative Agent), pay to the Administrative Agent for
the account of such Lender additional amounts sufficient to reimburse such
Lender for all such increased costs (except those incurred more than 60 days
prior to the date of such demand; for the purposes hereof any cost or expense
allocable to a period prior to the publication or effective date of such an
introduction, change, guideline or request shall be deemed to be incurred on the
later of such publication or effective date). Each Lender agrees to use its best
reasonable efforts promptly to notify the Borrower of any event referred to in
clause (i) or (ii) above, provided that the failure to give such notice shall
not affect the rights of any Lender under this Section 2.12(a) (except as
otherwise expressly provided above in this Section 2.12(a)). A certificate as to
the amount of such increased cost, submitted to the Borrower and the
Administrative Agent by such Lender, shall be conclusive and binding for all
purposes, absent manifest error. After one or more Lenders have notified the
Borrower of any increased costs pursuant to this Section 2.12, the Borrower may
specify by notice to the Administrative Agent and the affected Lenders that,
after the date of such notice whenever the election of a Eurodollar Rate Advance
by the Borrower for an Interest Period or portion thereof would give rise to
such increased costs, such election shall not apply to the Advances of such
Lender or Lenders during such Interest Period or portion thereof, and such
Advances shall during such Interest Period or portion thereof be (x) Prime Rate
Advances in lieu of Cdn. Dollar Eurodollar Rate Advances and (y) Base Rate
Advances in lieu of U.S. Dollar Eurodollar Rate Advances. Each Lender agrees to
use its best reasonable efforts (including a reasonable effort to change its
Applicable Lending Office or to transfer its affected Advances to an Affiliate
of such Lender) to avoid, or minimize the amount of, any demand for payment from
the Borrower under this Section 2.12, provided that such avoidance would not, in
the reasonable judgment of such Lender, be otherwise disadvantageous to such
Lender.

                  (b) In the event that any Lender shall have determined (which
determination shall be reasonably exercised and shall, absent manifest error, be
final, conclusive and binding upon all parties) at any time that the making of
or continuance of any Advance denominated in a currency other than Cdn. Dollars
has become unlawful as a result of compliance by such Lender


                                       31


in good faith with any applicable law, or by any applicable guideline or order
(whether or not having the force of law), or impossible as a result of the
market unavailability of such currency, then, in any such event, such Lender
shall give prompt notice (by telephone and confirmed in writing) to the Borrower
and the Administrative Agent of such determination (which notice the
Administrative Agent shall promptly transmit to the other Lenders). Upon the
giving of the notice to the Borrower and the Administrative Agent, the
Borrower's right to request (by Continuation or otherwise), and such Lender's
obligation to make, Advances denominated in a currency other than Cdn. Dollars
shall be immediately suspended, and thereafter, any requested Borrowings of
Advances denominated in a currency other than Cdn. Dollars shall, as to such
Lender only, be deemed to be a request for a Prime Rate Advance, and if the
affected Advance or Advances are still outstanding, the Borrower shall
immediately, or if permitted by applicable law, no later than the latest date
permitted thereby, upon at least one Business Days' prior written notice to the
Administrative Agent and the affected Lender, Continue each such Advance
denominated in a currency other than Cdn. Dollars as a Prime Rate Advance,
provided that if more than one Lender is affected at any time, then all affected
Lenders must be treated the same pursuant to this Section 2.12(b).

                  SECTION 2.13. INCREASED CAPITAL. If either (i) the
introduction of, or any change in or in the interpretation of, any law or
regulation or (ii) compliance by any Lender with any guideline or request from
any central bank or other governmental authority (whether or not having the
force of law) affects or would affect the amount of capital required or expected
to be maintained by such Lender or any corporation controlling such Lender
(including any determination after the Effective Date by any such central bank,
governmental authority or comparable agency that, for purposes of capital
adequacy requirements, the Commitments hereunder do not constitute commitments
with an original maturity of one year or less) and such Lender determines that
the amount of such capital is increased by or based upon the existence of such
Lender's commitment to lend hereunder and other commitments of this type, then,
within ten days after demand, and delivery to the Borrower of the certificate
referred to in the last sentence of this Section 2.13 by such Lender (with a
copy of such demand to the Administrative Agent), the Borrower shall pay to the
Administrative Agent for the account of such Lender, from time to time as
specified by such Lender, additional amounts sufficient to compensate such
Lender or such corporation in the light of such circumstances, to the extent
that such Lender reasonably determines such increase in capital to be allocable
to the existence of such Lender's commitment to lend hereunder (except any such
increase in capital incurred more than, or compensation attributable to the
period before, 90 days prior to the date of such demand; for the purposes hereof
any increase in capital allocable to, or compensation attributable to, a period
prior to the publication or effective date of such an introduction, change,
guideline or request shall be deemed to be incurred on the later of such
publication or effective date). Each Lender agrees to use its best reasonable
efforts promptly to notify the Borrower of any event referred to in clause (i)
or (ii) above, provided that the failure to give such notice shall not affect
the rights of any Lender under this Section 2.13 (except as otherwise expressly
provided above in this Section 2.13). A certificate in reasonable detail as to
the basis for, and the amount of, such compensation submitted to the Borrower
and the Administrative Agent by such Lender shall, in the absence of manifest
error, be conclusive and binding for all purposes.

                  SECTION 2.14. ILLEGALITY. Notwithstanding any other provision
of this Agreement, if the introduction of or any change in or in the
interpretation of any law or regulation shall make



                                       32


it unlawful, or any central bank or other governmental authority shall assert
that it is unlawful, for any Lender or its Applicable Lending Office to perform
its obligations hereunder to make Eurodollar Rate Advances of a particular Type
or to continue to fund or maintain such Advances hereunder, such Lender may, by
notice to the Borrower and the Administrative Agent, suspend the right of the
Borrower to elect Eurodollar Rate Advances of such Type from such Lender and, if
necessary in the reasonable opinion of such Lender to comply with such law or
regulation, Continue all such Eurodollar Rate Advances of such Lender as Prime
Rate Advances or Base Rate Advances, as applicable, at the latest time permitted
by the applicable law or regulation, and such suspension and, if applicable,
such Continuation shall continue until such Lender notifies the Borrower and the
Administrative Agent that the circumstances making it unlawful for such Lender
to perform such obligations no longer exist (which such Lender shall promptly do
when such circumstances no longer exist). So long as the obligation of any
Lender to make Eurodollar Rate Advances of such Type has been suspended under
this Section 2.14, all Notices of Borrowing specifying Advances of such Type
shall be deemed, as to such Lender, to be requests for Prime Rate Advances or
Base Rate Advances, as applicable. Each Lender agrees to use its best reasonable
efforts (including a reasonable effort to change its Applicable Lending Office
or to transfer its affected Advances to an Affiliate) to avoid any such
illegality, provided that such avoidance would not, in the reasonable judgment
of such Lender, be otherwise disadvantageous to such Lender.

                  SECTION 2.15. PAYMENTS AND COMPUTATIONS. (a) The Borrower
shall make each payment hereunder (including under Section 2.03, 2.05, or 2.06)
and under the Notes, whether the amount so paid is owing to any or all of the
Lenders or to the Administrative Agent, not later than 2:00 p.m. (Calgary local
time) without set-off, counterclaim, or any other deduction whatsoever, on the
day when due in (i) Cdn. Dollars, in the case of all fees required to be paid
under Section 2.03, and all amounts payable (whether principal or interest) in
respect of Prime Rate Advances and Cdn. Dollar Eurodollar Rate Advances and all
amounts payable (including the Acceptance Fee) in respect of B/A Advances, and
(ii) in U.S. Dollars, in the case of amounts payable (whether principal or
interest) in respect of Base Rate Advances and U.S. Dollar Eurodollar Rate
Advances, to the Administrative Agent in care of its Payment Office, or at such
other location designated by notice to the Borrower from the Administrative
Agent and agreed to by the Borrower, in same day funds. Each such payment made
by the Borrower for the account of any Lender hereunder, when so made to the
Administrative Agent, shall be deemed duly made for all purposes of this
Agreement and the Notes, except that if at any time any such payment is
rescinded or must otherwise be returned by the Administrative Agent or any
Lender upon the bankruptcy, insolvency or reorganization of the Borrower or
otherwise, such payment shall be deemed not to have been so made. The
Administrative Agent will promptly thereafter cause to be distributed like funds
relating to the payment of principal or interest or fees ratably (other than
amounts payable pursuant to Section 2.12, 2.13, 2.14, 2.16, 9.04(b) or 9.04(c))
to the Lenders for the account of their respective Applicable Lending Offices,
and like funds relating to the payment of any other amount payable to any Lender
to such Lender for the account of its Applicable Lending Office, in each case to
be applied in accordance with the terms of this Agreement. Upon its acceptance
of an Assignment and Acceptance and recording of the information contained
therein in the Register pursuant to Section 9.07(d), from and after the
effective date specified in such Assignment and Acceptance, the Administrative
Agent shall make all payments hereunder and under the Notes in respect of the
interest assigned thereby to the Lender assignee thereunder, and the parties to
such Assignment and Acceptance shall make



                                       33


all appropriate adjustments in such payments for periods prior to such effective
date directly between themselves.

                  (b) All computations of interest based on the Prime Rate and
under clause (i) of the definition of "Base Rate" and all computations of
Acceptance Fees (in the case of Bankers' Acceptances) and facility fees and
utilization fees (or amounts in lieu thereof) shall be made by the
Administrative Agent on the basis of a year of 365 or 366 days, as the case may
be, and all computations of interest based on the Eurodollar Rate or the
Effective Federal Funds Rate shall be made by the Administrative Agent, on the
basis of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest or fees are payable. Each determination by the
Administrative Agent (or, in the case of Section 2.12, 2.13, 2.14, 2.16, 9.04(b)
or 9.04(c), by each Lender with respect to its own Advances) of an interest rate
or an increased cost, loss or expense or increased capital or of illegality or
taxes hereunder shall be conclusive and binding for all purposes if made
reasonably and in good faith.

                  (c) Whenever any payment hereunder or under the Notes shall be
stated to be due on a day other than a Business Day, such payment shall be made
on the next succeeding Business Day, and such extension of time shall in such
case be included in the computation of payment of interest or facility fees, as
the case may be; provided, however, that except with respect to the Final
Maturity Date, if such extension would cause payment of interest on or principal
of Eurodollar Rate Advances to be made in the next following calendar month,
such payment shall be made on the next preceding Business Day.

                  (d) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due to the Lenders
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Lender on such
due date an amount equal to the amount then due such Lender. If and to the
extent the Borrower shall not have so made such payment in full to the
Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at a rate equal to the Prime Rate for such day.

                  SECTION 2.16. TAXES. (a) Any and all payments by the Borrower
or the Parent hereunder or under the Notes shall be made in accordance with
Section 2.15, free and clear of and without deduction for any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, imposed or levied by or on behalf of the
Government of Canada or of any province or territory thereof or by any authority
or agency therein or thereof having power to tax (hereinafter "CANADIAN TAXES"),
unless the Borrower is required to withhold or deduct Canadian Taxes by law or
by the interpretation or administration thereof. If the Borrower is so required
to withhold or deduct any amount for or on account of Canadian Taxes from any
payment made under or with respect to this Agreement or the Notes, the Borrower
will pay to each Indemnified Party as additional interest such additional
amounts as may be necessary so that the net amount received by each Indemnified
Party after such


                                       34


withholding or deduction (and after deducting any Canadian Taxes on such
additional amounts) will not be less than the amount the Indemnified Party would
have received if such Canadian Taxes had not been withheld or deducted. No
additional amounts will be payable with respect to a payment made to an
Indemnified Party under this Section 2.16(a) where such Indemnified Party (i) is
subject to Canadian Taxes by reason of the Indemnified Party being a resident,
domicile or national of, or engaging in business or maintaining a permanent
establishment or other physical presence in or otherwise having some connection
with Canada or any province or territory thereof otherwise than by the mere
making or holding of the Notes or by the receipt of payments thereunder, or (ii)
is subject to Canadian Taxes by reason of its failure to comply with Section
2.16(g), provided, that should an Indemnified Party become subject to Canadian
Taxes because of its failure to deliver a form required hereunder, the Borrower
or the Parent shall take such administrative steps as such Indemnified Party
shall reasonably request to assist such Indemnified Party to recover such
Canadian Taxes, and provided further, that each Indemnified Party, with respect
to itself, agrees to indemnify and hold harmless the Borrower and the Parent
from any Canadian Taxes, penalties, interest and other expenses, costs and
losses incurred or payable by the Borrower or the Parent as a result of the
failure of the Borrower or the Parent to comply with its obligations under this
Section 2.16(a) in reliance on any form or certificate provided to it by such
Indemnified Party pursuant to this Section 2.16. The Borrower will also make
such withholdings or deductions and remit the full amount deducted or withheld
to the relevant authority in accordance with applicable law.

                  (b) Any and all payments by the Parent (or by the Borrower to
the extent the Borrower causes a payment to be made from any jurisdiction other
than Canada) hereunder or under the Notes shall be made in accordance with
Section 2.15, free and clear of and without deduction for any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto imposed or levied by or on behalf of any
jurisdiction outside Canada, excluding in the case of each Indemnified Party all
taxes, levies, imposts, deductions, charges, or withholdings, and all
liabilities with respect thereto, imposed on or determined by reference to its
income or profits, and all franchise taxes and all other taxes, levies, imposts,
deductions, charges or withholdings in effect at the time that such Indemnified
Party executed this Agreement or otherwise became an "Indemnified Party"
hereunder, and liabilities with respect thereto, imposed on it by reason of the
jurisdiction in which such Indemnified Party is organized, domiciled, resident
or doing business, or any political subdivision thereof, or by reason of the
jurisdiction of its Applicable Lending Office or any other office from which it
makes or maintains any extension of credit hereunder or any political
subdivision thereof (all such non-excluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities in respect of payments under this
Agreement or under the Notes being herein referred to as "NON-CANADIAN TAXES"
and, together with Canadian Taxes, "TAXES"). If the Parent (or the Borrower, as
applicable) shall be required by law to deduct any Non-Canadian Taxes from or in
respect of any sum payable by it hereunder or under any Note to any Indemnified
Party, (i) the sum payable by it shall be increased as may be necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.16) such Indemnified Party receives
an amount equal to the sum it would have received had no such deductions been
made, (ii) the Parent (in the case of payments by it) (or Borrower (in the case
of payments by it) or the Administrative Agent, as applicable) shall make such
deductions at the applicable statutory rate and (iii) the Parent (in the case of
payments by it) (or the Borrower (in the case of payments by it) or the
Administrative Agent, as applicable)




                                       35


shall pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law, provided that the Parent shall not
be required to pay any additional amount (and shall be relieved of any liability
with respect thereto) pursuant to this subsection (b) (or pursuant to Section
2.16(e), except to the extent Section 2.16(e) relates to Other Taxes) to any
Indemnified Party that has failed to submit any form or certificate that it was
required to file or provide pursuant to Section 2.16(f) and is entitled to file
or give, as applicable, under applicable law, provided, further, that should an
Indemnified Party become subject to Non-Canadian Taxes because of its failure to
deliver a form required hereunder, the Parent shall take such administrative
steps as such Indemnified Party shall reasonably request to assist such
Indemnified Party to recover such Non-Canadian Taxes, and provided further, that
each Indemnified Party, with respect to itself, agrees to indemnify and hold
harmless the Parent from any taxes, penalties, interest and other expenses,
costs and losses incurred or payable by the Parent as a result of the failure of
the Parent to comply with its obligations under clauses (ii) or (iii) above in
reliance on any form or certificate provided to it by such Indemnified Party
pursuant to this Section 2.16.

                  (c) If any Indemnified Party receives a net credit or refund
in respect of Taxes or amounts paid pursuant to this Section 2.16 by the
Borrower or the Parent, it shall promptly notify the Borrower or the Parent of
such net credit or refund and shall promptly pay such net credit or refund to
the Borrower or the Parent, provided that the Borrower and the Parent agree to
return such net credit or refund if the Indemnified Party to which such net
credit or refund is applicable is required to repay it.

                  (d) In addition, the Parent and the Borrower agree to pay any
present or future stamp or documentary taxes or any other excise or property
taxes, charges or similar levies which arise from any payment made hereunder or
under the Notes or from the execution, delivery or registration of, or otherwise
with respect to, this Agreement or the Notes (hereinafter referred to as "OTHER
TAXES").

                  (e) The Borrower or the Parent will indemnify each Indemnified
Party for the full amount of Taxes or Other Taxes (including any Taxes or Other
Taxes imposed by any jurisdiction on amounts payable under this Section 2.16 but
excluding Canadian Taxes to the extent that such Indemnified Party is described
in either Section 2.16(a)(i) or (ii) hereof) paid by such Indemnified Party and
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto except as a result of the gross negligence (which shall in
any event include the failure of such Indemnified Party to provide any form or
certificate that it was required to provide either to the Borrower pursuant to
subsection (g) below or to the Parent pursuant to either subsection (f) or (g)
below) or willful misconduct of such Indemnified Party, whether or not such
Taxes or Other Taxes were correctly or legally asserted. This indemnification
shall be made within 30 days from the date such Indemnified Party makes written
demand therefor.

                  (f) On or prior to the date on which each Indemnified Party
that is not a United States person (as such term is defined in Section
7701(a)(30) of the Internal Revenue Code) executes this Agreement or otherwise
becomes an "Indemnified Party" hereunder, such Indemnified Party shall provide
the Parent and the Administrative Agent with U.S. Internal Revenue Service form
W-8BEN or W-8ECI, as appropriate, or any successor form prescribed by


                                       36


the U.S. Internal Revenue Service, certifying, if it is entitled to so certify,
that such Indemnified Party is fully exempt from United States withholding taxes
with respect to all payments to be made to such Indemnified Party hereunder, or
other documents satisfactory to the Parent indicating that all payments to be
made to such Indemnified Party hereunder are fully exempt from such taxes, if
such is the case. Thereafter and from time to time, each such Indemnified Party
shall submit to the Parent and the Administrative Agent such additional duly
completed and signed copies of one or the other of such forms (or such successor
forms as shall be adopted from time to time by the relevant United States taxing
authorities) as may be (i) notified by the Parent to such Indemnified Party and
(ii) required under then-current United States law or regulations to avoid
United States withholding taxes on payments in respect of all amounts to be
received by such Indemnified Party hereunder or under the Notes, including fees,
if the particular Indemnified Party is eligible for such exemption. Upon the
request of the Parent from time to time, each Indemnified Party that is a United
States person (as such term is defined in Section 7701(a)(30) of the Internal
Revenue Code) shall submit to the Parent a certificate to the effect that it is
such a United States person. If any Indemnified Party determines that it is not
fully exempt from United States withholding taxes with respect to all payments
to be received hereunder and is therefore unable to submit to the Parent any
form or certificate that such Indemnified Party would otherwise be obligated to
submit pursuant to this subsection (f), or that such Indemnified Party is
required to withdraw or cancel any such form or certificate previously submitted
because it is no longer entitled to such an exemption, such Indemnified Party
shall promptly notify the Parent and the Administrative Agent of such fact.

                  (g) In the event that, as a result of a Change in Law, Canada
or any political subdivision thereof introduces certification, identification,
information, documentation or other reporting requirements which require
compliance by an Indemnified Party as a pre-condition to an exemption from
withholding on Canadian Taxes for any payment made from Canada by the Borrower
or the Parent, hereunder or under the Notes (the "CANADIAN CERTIFICATION
REQUIREMENTS"), then such Indemnified Party shall provide the Parent, the
Borrower and the Administrative Agent with any applicable forms, certificates or
other documentation, as appropriate and as prescribed by the appropriate
Canadian governmental authority, certifying, if it is entitled to so certify,
that such Indemnified Party is so exempt from Canadian withholding taxes with
respect to payments to be made to such Indemnified Party, if such is the case.
Thereafter and from time to time, each such Indemnified Party shall submit to
the Parent, the Borrower and the Administrative Agent such additional duly
completed and signed copies of one or the other of such forms, certificates or
other documentation as may be notified by the Parent or by the Borrower to such
Indemnified Party and required under then-current Canadian law or regulations
(or the law or regulations of any political subdivision of Canada, if
applicable) to avoid Canadian withholding taxes on payments in respect of all
amounts to be received by such Indemnified Party pursuant to this Agreement or
the Notes, including fees, if the particular Indemnified Party is eligible for
such exemption. If any Indemnified Party determines that it is not exempt from
Canadian withholding taxes with respect to all payments to be received hereunder
and is therefore unable to submit to the Parent, the Borrower or the
Administrative Agent any form, certificate or other documentation that such
Indemnified Party would otherwise be obligated to submit pursuant to this
subsection (g), or that such Indemnified Party is required to withdraw or cancel
any such form, certificate or documentation previously submitted because it is
no longer entitled to such an exemption, then such Indemnified Party shall
promptly notify the Parent, the Borrower and the Administrative Agent of such
fact. The Borrower and the Parent


                                       37


acknowledge that no such Canadian Certification Requirements currently exist
under Canadian law. The obligations of each Indemnified Party under this Section
2.16(g) shall not be effective with respect to such Indemnified Party unless and
until either the Parent, the Borrower or the Administrative Agent provides
written notice to such Indemnified Party of any such Canadian Certification
Requirements and extends to such Indemnified Party a reasonable amount of time,
not to exceed 30 days, to comply with any such requirements.

                  (h) Any Indemnified Party claiming any additional amounts
payable pursuant to this Section 2.16 shall use its best reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to
change the jurisdiction of its Applicable Lending Office if the making of such a
change would avoid the need for, or reduce the amount of, any such additional
amounts which may thereafter accrue and would not, in the reasonable judgment of
such Indemnified Party, be otherwise disadvantageous to such Indemnified Party.

                  (i) Without prejudice to the survival of any other agreement
of the Borrower and the Parent hereunder, the agreements and obligations of the
Borrower, the Parent and each Indemnified Party contained in this Section 2.16
shall survive the payment in full of principal and interest hereunder and under
the Notes.

                  SECTION 2.17. SHARING OF PAYMENTS, ETC. If any Lender shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) on account of the Advances made by it (other
than pursuant to Section 2.12, 2.13, 2.14, 2.16, 9.04(b) or 9.04(c)) in excess
of its ratable share of payments on account of the Advances obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the Advances made by them as shall be necessary to cause such
purchasing Lender to share the excess payment ratably with each of them,
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and each Lender shall repay to the purchasing Lender the
purchase price to the extent of such Lender's ratable share (according to the
proportion of (i) the amount of the participation purchased from such Lender as
a result of such excess payment to (ii) the total amount of such excess payment)
of such recovery together with an amount equal to such Lender's ratable share
(according to the proportion of (A) the amount of such Lender's required
repayment to (B) 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. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 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 the direct creditor of the Borrower in the amount of such
participation.

                  SECTION 2.18. EVIDENCE OF DEBT. (a) Each Lender shall maintain
in accordance with its usual practice an account or accounts evidencing the
Indebtedness of the Borrower to such Lender resulting from each Advance made by
such Lender hereunder, including the amounts of principal and interest payable
and paid to such lender from time to time hereunder.

                  (b) The Administrative Agent shall maintain accounts and
records in which it shall record (i) the amount of each Advance made hereunder,
the type of Advance and, in the


                                       38


cases of B/A Advances and Eurodollar Rate Advances, the relevant Contract Period
or Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder, and (iii) the amount of any sum received by the Administrative
Agent hereunder for the account of the Lenders and each Lender's share thereof.

                  (c) The entries made in the accounts maintained pursuant to
Sections 2.18(a) and (b) shall be conclusive evidence (absent manifest error) of
the existence and amounts of the obligations recorded therein; provided that the
failure of any Lender or the Administrative Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of the Borrower
to repay the Advances in accordance with the terms of this Agreement. In the
event of a conflict between the records maintained by the Administrative Agent
and any Lender, the records maintained by the Lender shall govern. Any Lender
may request that Loans (other than B/As) made by it be evidenced by a Note. In
such event, the Borrower shall prepare, execute and deliver to such Lender a
Note payable to the order of such Lender (or, if requested by such Lender, to
such Lender and its registered assigns) and substantially in the form attached
as Exhibit A hereto. Thereafter, the Loans evidenced by such Note and interest
thereon shall at all times (including after assignment pursuant to Section 9.07)
be represented by one or more Notes in such form payable to the order of the
payee named therein (or, if such Note is a registered Note, to such payee and
its registered assigns).

                  SECTION 2.19. USE OF PROCEEDS. Proceeds of the Advances may be
used for general corporate purposes of the Borrower and its Subsidiaries and of
Parent and any of its other Subsidiaries, including for acquisitions and for
payment of commercial paper issued by the Borrower or any such other Person.

                  SECTION 2.20. INCREASE OF COMMITMENTS. (a) At any time after
the Effective Date, provided that no Event of Default shall have occurred and be
continuing, the Borrower may request an increase of the aggregate Commitments by
notice to the Administrative Agent in writing of the amount (the "Offered
Increase Amount") of such proposed increase (such notice, a "Commitment Increase
Notice"). Any such Commitment Increase Notice must offer each Lender the
opportunity to subscribe for its pro rata share of the increased Commitments. If
any portion of the increased Commitments is not subscribed for by the Lenders,
the Borrower may, in its sole discretion, but with the consent of the
Administrative Agent as to any Person that is not at such time a Lender (which
consent shall not be unreasonably withheld), offer to any existing Lender or to
one or more additional banks or financial institutions the opportunity to
participate in all or a portion of such unsubscribed portion of the increased
Commitments pursuant to paragraph (b) or (c) below, as applicable.

                  (b) Any additional bank or financial institution that the
Borrower selects to offer participation in the increased Commitments, and that
elects to become a party to this Agreement and obtain a Commitment, shall
execute a New Lender Agreement with the Borrower and the Administrative Agent,
substantially in the form of Exhibit E (a "NEW LENDER AGREEMENT"), whereupon
such bank or financial institution (a "NEW LENDER") shall become a Lender for
all purposes and to the same extent as if originally a party hereto and shall be
bound by and entitled to the benefits of this Agreement, and the signature pages
and Schedule III hereof shall be deemed to be amended to add the name and
Commitment of such New Lender, provided

                                       39

that the Commitment of any such New Lender shall be in an amount not less than
Cdn.$5,000,000.

                  (c) Any Lender that accepts an offer to it by the Borrower to
increase its Commitment pursuant to this Section 2.20 shall, in each case,
execute a Commitment Increase Agreement with the Borrower and the Administrative
Agent, substantially in the form of Exhibit F (a "COMMITMENT INCREASE
AGREEMENT"), whereupon such Lender shall be bound by and entitled to the
benefits of this Agreement with respect to the full amount of its Commitment as
so increased, and Schedule III hereof shall be deemed to be amended to so
increase the Commitment of such Lender.

                  (d) The effectiveness of any New Lender Agreement or
Commitment Increase Agreement shall be contingent upon receipt by the
Administrative Agent of such corporate resolutions of the Borrower and legal
opinions of counsel to the Borrower as the Administrative Agent shall reasonably
request with respect thereto, in each case, in form and substance satisfactory
to the Administrative Agent.

                  (e) If any bank or financial institution becomes a New Lender
pursuant to Section 2.20(b) or any Lender's Commitment is increased pursuant to
Section 2.20(c), additional Advances made on or after the effectiveness thereof
(the "RE-ALLOCATION DATE") shall be made pro rata based on the Commitment
Percentages in effect on and after such Re-Allocation Date (except to the extent
that any such pro rata borrowings would result in any Lender making an aggregate
principal amount of Advances in excess of its Commitment, in which case such
excess amount will be allocated to, and made by, such New Lender and/or Lenders
with such increased Commitments to the extent of, and pro rata based on, their
respective Commitments), and continuations of Eurodollar Rate Advances
outstanding on such Re-Allocation Date shall be effected by repayment of such
Eurodollar Rate Advances on the last day of the Interest Period applicable
thereto and the making of new Eurodollar Rate Advances pro rata based on such
new Commitment Percentages. In the event that on any such Re-Allocation Date
there is an unpaid principal amount of Prime Rate Advances or Base Rate
Advances, the existing Lenders shall be deemed to have made partial assignments
thereof to the New Lenders and/or Lenders with such increased Commitments in
such amounts that, after giving effect thereto, the Prime Rate Advances and Base
Rate Advances outstanding are held pro rata based on such new Commitment
Percentages. In the event that on any such Re-Allocation Date there is an unpaid
principal amount of Eurodollar Rate Advances, such Eurodollar Rate Advances
shall remain outstanding with the respective holders thereof until the
expiration of their respective Interest Periods (unless the applicable Borrower
elects to prepay any thereof in accordance with the applicable provisions of
this Agreement), and interest on and repayments of such Eurodollar Rate Advances
will be paid thereon to the respective Lenders holding such Eurodollar Rate
Advances pro rata based on the respective principal amounts thereof outstanding.
In the event that on any such Re-Allocation Date there is an unpaid principal
amount of B/A Advances, such B/A Advances shall remain outstanding with the
respective holders thereof until the expiration of their respective Contract
Periods, and repayments of such B/A Advances will be paid thereon to the
respective Lenders holding such B/As based on the respective face amounts
thereof.

                  (f) Notwithstanding anything to the contrary in this Section
2.20, (i) no increase pursuant to this Section 2.20 shall be effective without
the consent of the Required


                                       40


Lenders, (ii) no Lender shall have any obligation to increase its Commitment
unless it agrees to do so in its sole discretion and (iii) the aggregate amount
by which the Commitments hereunder are increased pursuant to this Section 2.20
shall not exceed Cdn.$141,426,000.

                  (g) The Borrower shall execute and deliver a Note to each new
bank or other financial institution becoming a Lender that requests one.

                  SECTION 2.21. EXTENSION OF REVOLVING COMMITMENT TERMINATION
DATE. (a) Not earlier than 65 days prior to and not later than 45 days prior to
the Revolving Commitment Termination Date then in effect, provided that no Event
of Default shall have occurred and be continuing, the Borrower may request an
extension of such Revolving Commitment Termination Date by submitting to the
Administrative Agent an Extension Request containing the information in respect
of such extension specified in Exhibit G, which the Administrative Agent shall
promptly furnish to each Lender. Each Lender shall, by the later of (i) the date
30 days after its receipt from the Administrative Agent of the applicable
Extension Request and (ii) the date 30 days prior to the Revolving Commitment
Termination Date, notify the Borrower and the Administrative Agent of its
consent to extend or its refusal to extend the Revolving Commitment Termination
Date as requested in such Extension Request. Any such Extension Request shall be
approved if the Required Lenders shall approve in writing the extension of the
Revolving Commitment Termination Date requested in such Extension Request. The
Borrower may request no more than ten extensions pursuant to this Section 2.21,
so that the Revolving Commitment Termination Date shall not in any event extend
beyond the tenth anniversary of the initial Revolving Commitment Termination
Date hereunder. The Administrative Agent shall promptly notify the Lenders and
the Borrower of any extension of the Revolving Commitment Termination Date
pursuant to this Section 2.21 and shall promptly notify the Borrower of any
Lender that has notified the Administrative Agent of its consent to extend or
its refusal to extend the Revolving Commitment Termination Date.

                  (b) If any such Extension Request is approved but there are
one or more Lenders that do not consent to the Extension Request in writing
within the period specified in paragraph (a) above (an "Objecting Lender"), the
Borrower shall be entitled to choose any of the following options prior to the
Revolving Commitment Termination Date, provided that if the Borrower does not
make an election prior to such date, the Borrower shall be deemed to have
irrevocably elected to exercise the option in clause (iii)(y) below:

                  (i) the Borrower may elect to cause the Commitments and
         Advances of any Objecting Lender to be transferred or assigned pursuant
         to Section 2.21(c); and/or

                  (ii) the Borrower may elect to voluntarily prepay the
         Advances, if any, of Objecting Lenders together with accrued interest
         thereon, any amounts payable pursuant to Sections 2.06, 2.12, 2.13,
         2.16 and 9.04(b) and any accrued and unpaid facility fee or utilization
         fee or other amounts payable with respect to such Objecting Lenders,
         and the Commitments of such Objecting Lenders shall be terminated; or

                  (iii) the Borrower may elect to revoke and cancel the
         Extension Request by giving notice of such revocation and cancellation
         to the Administrative Agent (which shall promptly notify the Lenders
         thereof) and concurrently therewith shall have the


                                       41


         option to (x) voluntarily prepay the Advances, if any, of all Lenders,
         together with accrued interest thereon, any amounts payable pursuant to
         Sections 2.06, 2.12, 2.13, 2.16 and 9.04(b) and any accrued and unpaid
         facility fee or utilization fee or other amounts payable with respect
         to the Lenders, and the Commitments of all Lenders shall be terminated
         or (y) have the outstanding Advances continue as term loans repayable
         in accordance with paragraphs (a), (b), (c) and (d) of Section 2.05 of
         this Agreement.

                  (c) If any Lender becomes an Objecting Lender, the Borrower
may, at its own expense and in its sole discretion and prior to the then
Revolving Commitment Termination Date, require such Lender to transfer or
assign, without recourse (in accordance with Section 8.07), all of its
interests, rights and obligations under this Agreement and, if the Borrower
shall so determine in its sole discretion, all or part of its interest, rights
and obligations under the U.S. Long-Term Revolving Credit Agreement and/or the
U.S. Short-Term Revolving Credit Agreement, as the case may be) to an Eligible
Assignee (provided that the Borrower, with the full cooperation of such Lender,
can identify an Eligible Assignee that is ready, willing and able to be an
assignee with respect thereto) which shall assume such assigned obligations
(which assignee may be another Lender, if such assignee Lender accepts such
assignment); provided that (A) the assignee or the Borrower, as the case may be,
shall have paid to such Lender in immediately available funds the principal of
and interest accrued to the date of such payment on the Advances made by it
hereunder and the "Advances" made by it under, and as defined in, the U.S.
Long-Term Revolving Credit Agreement or the U.S. Short-Term Revolving Credit
Agreement, as the case may be, and all other amounts owed to it hereunder and
thereunder, including any amounts owing pursuant to Section 9.04(b) (or the
comparable provision of the U.S. Long-Term Revolving Credit Agreement or the
U.S. Short-Term Revolving Credit Agreement, as the case may be) and any amounts
that would be owing under such Section (or comparable provision) if such
Advances and "Advances" (as so defined) were prepaid on the date of such
assignment, and (B) such assignment does not conflict with any law, rule or
regulation or order of any governmental authority. Any assignee that becomes a
Lender as a result of such an assignment made pursuant to this paragraph (b)
shall be deemed to have consented to the applicable Extension Request and,
therefore, shall not be an Objecting Lender.

                  SECTION 2.22. REPLACEMENT OF LENDERS. If any Lender requests
compensation under Sections 2.11 or 2.13 or if the Borrower is required to pay
any additional amount to any Lender or any taxing authority or other authority
for the account of any Lender pursuant to Section 2.16, or if any Lender
suspends the right of the Borrower to elect Eurodollar Rate Advances from such
Lender pursuant to Section 2.14, or if any Lender defaults in its obligation to
fund Advances hereunder, then the Borrower may, at its sole expense and effort,
upon notice to such Lender and the Administrative Agent, require such Lender to
assign and delegate, without recourse (in accordance with and subject to the
restrictions contained in Section 9.07), all its interests, rights and
obligations under this Agreement and, if the Borrower shall so determine in its
sole discretion, the U.S. Long-Term Revolving Credit Agreement and/or the U.S.
Short-Term Revolving Credit Agreement, as the Borrower may determine in its sole
discretion and specify by notice to such Lender, (other than "B Advances" under,
and as defined in, the U.S. Long-Term Revolving Credit Agreement and/or the U.S.
Short-Term Revolving Credit Agreement, as the case may be) to an assignee that
shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (i) the Borrower shall have received the
prior written consent of the Administrative Agent, which


                                       42


consent shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Advances
hereunder and, if the Borrower shall have so determined as specified above, its
"Advances" (other than "B Advances") (each under and as defined in the U.S.
Long-Term Revolving Credit Agreement and/or the U.S. Short-Term Revolving Credit
Agreement, as the case may be), and all accrued interest thereon, accrued fees,
accrued costs in connection with compensation under Sections 2.12 or 2.13 or
payments required to be made pursuant to Section 2.16, if any, and all other
amounts (other than "B Advances") payable to it hereunder and, if the Borrower
shall have so determined as specified above, under the U.S. Long-Term Revolving
Credit Agreement and/or the U.S. Short-Term Revolving Credit Agreement, as the
case may be, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrower (in the case of all other amounts)
and (iii) in the case of any such assignment resulting from a claim for
compensation under Sections 2.12 or 2.13 or payments required to be made
pursuant to Section 2.16, such assignment will result in a reduction in such
compensation or payments. A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply.

                  SECTION 2.23. CURRENCY INDEMNITY. If, for the purposes of
obtaining judgment in any court in any jurisdiction with respect to this
Agreement or any other Financing Document, it becomes necessary to convert into
the currency of such jurisdiction (the "Judgment Currency") any amount due under
this Agreement or under any other Financing Document in any currency other than
the Judgment Currency (the "Currency Due"), then conversion shall be made at the
rate of exchange prevailing on the Business Day before the day on which the
judgment is given. For this purpose, "rate of exchange" means the rate at which
the Administrative Agent is able, on the relevant date, to purchase the Currency
Due with the Judgment Currency in accordance with its normal practice at its
head office in Toronto, Ontario. In the event that there is a change in the rate
of exchange prevailing between the Business Day before the day on which the
judgment is given and the date of receipt by the Administrative Agent of the
amount due, the Borrower will, on the date of receipt by the Administrative
Agent, pay such additional amounts, if any, or be entitled to obtain
reimbursement of such amount, if any, as may be necessary to ensure that the
amount received by the Administrative Agent on such date is the amount in the
Judgment Currency which when converted at the rate of exchange prevailing on the
date of receipt by the Administrative Agent is the amount then due under this
Agreement or under such other Financing Document in the Currency Due. If the
amount of the Currency Due which the Administrative Agent is so able to purchase
is less than the amount of the Currency Due originally due to it, the Borrower
shall indemnify and save the Administrative Agent and the Lenders harmless from
and against all loss or damage arising as a result of such deficiency. This
indemnity shall constitute an obligation separate and independent from the other
obligations contained in this Agreement and the other Financing Documents, shall
give rise to a separate and independent cause of action, shall apply
irrespective of any indulgence granted by the Administrative Agent from time to
time and shall continue in full force and effect notwithstanding any judgment or
order for a liquidated sum in respect of an amount due under this Agreement or
any other Financing Document or under any judgment or order.

                  SECTION 2.24. EXCHANGE RATE CALCULATIONS. (a) Not later than
12:00 noon, Calgary local time, on each Calculation Date, the Administrative
Agent shall (i) determine the




                                       43


Exchange Rate as of such Calculation Date and (ii) give notice thereof to the
Borrower and to each Lender that shall have requested such information. The
Exchange Rates so determined shall become effective on the first Business Day
immediately following the relevant Calculation Date (each, a "Reset Date") and
shall remain effective until the next succeeding Reset Date.

                  (b) Not later than 12:00 noon, Calgary local time, on each
Reset Date, the Administrative Agent shall (i) determine the Cdn.$ Equivalent of
the Advances outstanding on such date, or to be outstanding after giving effect
to any Borrowing to occur on such date, and (ii) notify the Borrower and each
Lender that shall have requested such information of the aggregate outstanding
Advances, based on information provided by the Borrower after giving effect to
all Advances and all repayments and prepayments to occur on such date.

                                   ARTICLE 3

                     CONDITIONS OF EFFECTIVENESS AND LENDING

                  SECTION 3.01. CONDITIONS PRECEDENT TO EFFECTIVENESS OF THIS
AGREEMENT. This Agreement shall become effective when (i) it shall have been
executed by the Borrower, Parent and the Administrative Agent, (ii) the
Administrative Agent and the Borrower either shall have been notified by each
Initial Lender that such Initial Lender has executed it or shall have received a
counterpart of this Agreement executed by such Initial Lender, and (iii) the
Administrative Agent shall have received the following, each dated the date of
delivery thereof unless otherwise specified below (which date shall be selected
by the Borrower and be the same for all documents and all Lenders), in form and
substance satisfactory to the Administrative Agent and (except for the Notes, if
any) in sufficient copies for each Lender:

                  (a) the Notes, to the order of the Lenders requesting Notes,

the Borrowings contemplated hereby and authorizing the execution of this
Agreement and the other Financing Documents, including the Notes, if any, and of
all documents evidencing other necessary corporate action and governmental
approvals, if any, with respect to this Agreement and any other Financing
Documents;

                  (c) a certificate of the Secretary or an Assistant Secretary
of the Borrower and Parent (i) certifying names and true signatures of officers
of such Person authorized to sign this Agreement, the Notes, if any, and any
other Financing Documents to which it is a party and (ii) if the Effective Date
is other than the date of this amendment and restatement, certifying that the
representations and warranties contained in Section 4.01 are true and correct as
of the Effective Date;

                  (d) Evidence of the effectiveness of the amendment and

                         REPRESENTATIONS AND WARRANTIES

                  SECTION 4.01. REPRESENTATIONS AND WARRANTIES OF THE BORROWER.
Each of the Borrower and Parent represents and warrants as follows:

                  (a) The Borrower is a corporation duly amalgamated, validly
existing and in good standing under the laws of the Province of Alberta. The
Parent is a corporation duly incorporated, validly existing and in good standing
under the laws of the State of Delaware. Each Material Subsidiary is duly
incorporated, validly existing and in good standing in the jurisdiction of its
incorporation. Parent and each Material Subsidiary possess all corporate powers
and all other authorizations and licenses necessary to engage in its business
and operations as now conducted, the failure to obtain or maintain which would
have a Material Adverse Effect. Each Subsidiary of Parent that is, on and as of
the Effective Date, a Material Subsidiary is listed on Schedule I hereto.

                  (b) The Transactions are within the corporate powers of the
Borrower and Parent (as applicable), have been duly authorized by all necessary
corporate action, and do not contravene (i) the charter or certificate of
incorporation (as applicable) or by-laws of the Borrower or the Parent (as
applicable) or (ii) law or any contractual restriction binding on or affecting
the Borrower or the Parent. This Agreement, the Notes, if any, and the other
Financing Documents, if any, have been duly executed and delivered by the
Borrower and the Parent (as applicable).

                  (c) The Transactions do not require any authorization or
approval or other action by, nor any notice to or filing with, any governmental
authority or regulatory body for the due execution, delivery and performance by
the Borrower and the Parent (as applicable) of this Agreement, the Notes, if
any, or the other Financing Documents, if any, as applicable, that has not been
duly made or obtained, except those (i) required in the ordinary course to
comply with ongoing covenant obligations of the Borrower and Parent hereunder
the performance of which is not yet due and (ii) that will, in the ordinary
course of business in accordance with this Agreement, be duly made or obtained
on or prior to the time or times the performance of such obligations shall be
due.

                  (d) This Agreement constitutes, and the Notes (if and when
delivered hereunder) and the other Financing Documents, if any, when delivered
hereunder shall constitute, legal, valid and binding obligations of the Borrower
or the Parent (as applicable) enforceable against each such Person in accordance
with their respective terms, except as may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting
creditors' rights generally or by general principles of equity.

                  (e) The consolidated balance sheet of the Parent and its
consolidated Subsidiaries as at December 31, 2000 and the related consolidated
statements of income and cash flow for the fiscal year then ended, reported on
by PricewaterhouseCoopers LLC, independent public accountants, and the
consolidated balance sheet of the Parent and its consolidated subsidiaries as at
September 30, 2001 and the related consolidated statements of income and cash




                                       46


flow for the nine-month period then ended, certified by the chief financial
officer of the Parent, copies of each of which have been furnished to the
Administrative Agent and the Initial Lenders, fairly present the consolidated
financial condition of the Parent and such Subsidiaries as at December 31, 2000,
and September 30, 2001, respectively, and the consolidated results of their
operations for such fiscal periods, subject in the case of the September 30,
2001, statements to normal year-end adjustments, all in accordance with
generally accepted accounting principles consistently applied. From September
30, 2001 to and including the Effective Date there has been no material adverse
change in such condition or results of operations.

                  (f) As at the Effective Date, there is no action, suit or
proceeding pending, or to the knowledge of the Borrower and Parent threatened,
against or involving Parent or any Material Subsidiary in any court, or before
any arbitrator of any kind, or before or by any governmental body, which in the
reasonable judgment of the Borrower and Parent (taking into account the
exhaustion of all appeals) would have a material adverse effect on the
consolidated financial condition of Parent and its consolidated Subsidiaries
taken as a whole, or which purports to affect the legality, validity, binding
effect or enforceability of this Agreement, the Notes, if any, or the other
Financing Documents, if any.

                  (g) Parent and each of its consolidated Subsidiaries has duly
filed all tax returns required to be filed, and duly paid and discharged all
taxes, assessments and governmental charges upon it or against its properties
now due and payable, the failure to file or pay which, as applicable, would have
a Material Adverse Effect, unless and to the extent only that the same are being
contested in good faith and by appropriate proceedings by the Borrower or the
appropriate Subsidiary.

                  (h) Except to the extent permitted pursuant to Section
5.02(e), neither Parent nor any Material Subsidiary is subject to any
contractual restrictions which limit the amount of dividends payable by any
Subsidiary.

                  (i) No Termination Event has occurred or is reasonably
expected to occur with respect to any Plan which, with the giving of notice or
lapse of time, or both, would constitute an Event of Default under Section
6.01(g).

                  (j) Neither Parent nor any ERISA Affiliate has incurred, or is
reasonably expected to incur, any Withdrawal Liability to any Multiemployer Plan
that, when aggregated with all other amounts required to be paid to
Multiemployer Plans in connection with Withdrawal Liability (as of the date of
determination), exceeds 5% of the Consolidated Tangible Net Worth of Parent.

                  (k) Neither Parent nor any ERISA Affiliate has received any
notification that any Multiemployer Plan is in reorganization or has been
terminated, within the meaning of Title IV of ERISA, and no Multiemployer Plan
is reasonably expected to be in reorganization or to be terminated within the
meaning of Title IV of ERISA the effect of which reorganization or termination
would be the occurrence of an Event of Default under Section 6.01(i).



                                       47


                  (l) Neither Parent nor the Borrower is an "investment company"
or a "company" controlled by an "investment company" within the meaning of the
United States Investment Company Act of 1940, as amended.

                  (m) Neither Parent nor the Borrower is a "holding company" or
a "subsidiary company" of a "holding company", or an "affiliate" of a "holding
company" or of a "subsidiary company" of a "holding company", or a "public
utility" within the meaning of the United States Public Utility Holding Company
Act of 1935, as amended.

                  All representations and warranties made by the Borrower and/or
Parent herein or made in any certificate delivered pursuant hereto shall survive
the making of the Advances and the execution and delivery to the Lenders of this
Agreement and the Notes.

                                   ARTICLE 5

                                   COVENANTS

                  SECTION 5.01. AFFIRMATIVE COVENANTS. So long as any Advance,
Note or other amount payable by the Borrower hereunder shall remain unpaid or
any Lender shall have any Commitment hereunder, Parent will, unless the Majority
Lenders shall otherwise consent in writing:

                  (a) PRESERVATION OF CORPORATE EXISTENCE, ETC. Preserve and
maintain, and cause each Material Subsidiary to preserve and maintain, its
existence, rights (organizational and statutory) and material franchises, except
as otherwise contemplated or permitted by Section 5.02(c) or 5.02(d); provided,
that any Material Subsidiary may change its form of organization to a
partnership or other form of Business Entity, provided further that in the case
of any such change by the Borrower, its jurisdiction of organization remains in
Canada, and in connection with any such change by the Borrower, the Borrower
shall cause to be delivered to the Administrative Agent a legal opinion of
counsel acceptable to the Administrative Agent to the effect that the successor
entity to the Borrower continues to be bound by, or has assumed by instrument or
by operation of law, all of the Borrower's obligations under this Agreement and
the Notes.

                  (b) COMPLIANCE WITH LAWS, ETC. Comply, and cause each
Subsidiary to comply, in all material respects, with all applicable laws, rules,
regulations and orders (including all environmental laws and laws requiring
payment of all taxes, assessments and governmental charges imposed upon it or
upon its property except to the extent contested in good faith by appropriate
proceedings) the failure to comply with which would have a Material Adverse
Effect.

                  (c) VISITATION RIGHTS. At such reasonable times and intervals
as the Administrative Agent or any of the Lenders may desire, permit the
Administrative Agent or any of the Lenders to visit the Borrower and to discuss
the affairs, finances, accounts and mineral reserve performance of Parent and
any of its Subsidiaries with officers of the Borrower and Parent and independent
certified public accountants of Parent and any of its Subsidiaries, provided
that if an Event of Default, or an event which with the giving of notice or the
passage of

                                       48


time, or both, would become an Event of Default, has occurred and is
continuing, the Administrative Agent or any Lender may, in addition to the other
provisions of this subsection (c) and at such reasonable times and intervals as
the Administrative Agent or any of the Lenders may desire, visit and inspect,
under guidance of officers of Parent (or, in the case of properties of the
Borrower or its Subsidiaries, of the Borrower), as the case may be, any
properties significant to the consolidated operations of Parent and its
Subsidiaries, and to examine the books and records of account (other than with
respect to any mineral reserve information that Parent determines to be
confidential, except, during the continuation of an Event of Default, if such
Lenders shall have entered into a confidentiality agreement with respect to such
information satisfactory in form and substance to Parent) Parent and any of its
Subsidiaries and to discuss the affairs, finances and accounts of any of the
Subsidiaries of Parent with any of the officers of such Subsidiary.

                  (d) BOOKS AND RECORDS. Keep, and cause each of its
Subsidiaries to keep, proper books of record and account, in which full and
correct entries shall be made of all financial transactions and the assets and
business of Parent and each Subsidiary of Parent in accordance with GAAP either
(i) consistently applied or (ii) applied in a changed manner that does not,
under GAAP or public reporting requirements applicable to Parent either require
disclosure in the consolidated financial statements of Parent and its
consolidated Subsidiaries or require the consent of the accountants which (as
required by Section 5.03(b)) report on such financial statements for the fiscal
year in which such change shall have occurred, or (iii) applied in a changed
manner not covered by clause (ii) above provided such change shall have been
disclosed to the Administrative Agent and shall have been consented to by the
accountants which (as required by Section 5.03(b)) report on the consolidated
financial statements of Parent and its consolidated Subsidiaries for the fiscal
year in which such change shall have occurred, provided further that if any
change referred to in clause (ii) or (iii) above would not meet the standard set
forth in clause (i) or (ii) of Section 1.03, the Administrative Agent, the
Lenders, the Borrower and Parent agree to amend the covenants contained in
Section 5.01 and 5.02 so that the relative protection afforded thereby to the
Lenders and the relative flexibility afforded thereby to the Borrower will in
substance be retained after such amendment, provided further, however, that
until such amendment becomes effective hereunder, the covenants as set forth
herein shall remain in full force and effect and those accounting principles
applicable to Parent and its consolidated Subsidiaries which do meet the
standards set forth in clause (i) or (ii) of Section 1.03 shall be applied to
determine whether or not the Borrower is in compliance with such covenants.

                  (e) MAINTENANCE OF PROPERTIES, ETC. Maintain and preserve, and
cause each Material Subsidiary to maintain and preserve, all of its properties
which are used in the conduct of its business in good working order and
condition, ordinary wear and tear excepted, to the extent that any failure to do
so would have a Material Adverse Effect.

                  (f) MAINTENANCE OF INSURANCE. Maintain, and cause each
Material Subsidiary to maintain, insurance with responsible and reputable
insurance companies or associations in such amounts and covering such risks as
is usually carried by companies engaged in similar businesses and owning similar
properties in the same general areas in which Parent or such Subsidiary
operates.


                                       49


                  SECTION 5.02. NEGATIVE COVENANTS. So long as any Advance, Note
or other amount payable by the Borrower hereunder shall remain unpaid or any

Lenders shall otherwise consent in writing:

                  (a) LIENS, ETC. (i) Create, assume or suffer to exist, or
permit any Material Subsidiary to create, assume or suffer to exist, any Liens
upon or with respect to any of the Equity Interests in any Material Subsidiary,

Material Subsidiary to create or assume, any Liens upon or with respect to any
other assets material to the consolidated operations of Parent and its
consolidated Subsidiaries taken as a whole securing the payment of Debt and
Guaranties in an aggregate amount (determined without duplication of amount (so
that the amount of a Guaranty will be excluded to the extent the Debt Guaranteed
thereby is included in computing such aggregate amount)) exceeding the greater
of (x) U.S.$250,000,000 and (y) 10% of Consolidated Tangible Net Worth as at the
date of such creation or assumption; provided, however, that this subsection (a)
shall not apply to:

         Subsidiaries after the Original Effective Date to the extent that such
         Liens existed at the time of such acquisition and were not placed
         thereon by or with the consent of Parent in contemplation of such
         acquisition;

                  (B) Liens on Equity Interests acquired after the Original
         Effective Date in a Business Entity which has become or becomes a

         extent that such Liens existed at the time of such acquisition and were
         not placed thereon by or with the consent of Parent in contemplation of
         such acquisition;

                  (C) Liens on Margin Stock;

                  (D) Liens on the Equity Interests in, or Debt or other

         which are owned by any Project Financing Subsidiary) securing the
         payment of a Project Financing and related obligations;

                  (E) Permitted Liens;

                  (F) Liens arising out of the refinancing, extension, renewal
         or refunding of any Debt or Guaranty secured by any Lien permitted by
         any of the foregoing clauses of this Section, provided that the
         principal amount of such Debt or Guaranty is not increased (except by
         the amount of costs reasonably incurred in connection with the issuance
         thereof) and such Debt or Guaranty is not secured by any additional
         assets that would not have been permitted by this Section to secure the
         Debt or Guaranty refinanced, extended, renewed or refunded; and

                  (G) Liens on products and proceeds (including dividend,
         interest and like payments on, and insurance and condemnation proceeds
         and rental, lease, licensing and similar proceeds) of, and property
         evidencing or embodying, or constituting rights or

         other general intangibles relating to, and accessions and improvements
         to, collateral subject to Liens permitted by this Section 5.02.

                  (b) DEBT, ETC. Create, assume or suffer to exist, or permit
any of its consolidated Subsidiaries to create, assume or suffer to exist, any
Debt or any Guaranty unless, immediately after giving effect to such Debt or
Guaranty and the receipt and application of any proceeds thereof or value
received in connection therewith,

                  (1) the sum (without duplication) of (i) consolidated Debt of
         Parent and its consolidated Subsidiaries plus (ii) the aggregate amount

         consolidated Subsidiaries is less than 60% of Capitalization, provided
         that Debt for borrowed money either maturing within one year and
         evidenced by instruments commonly known as commercial paper, or

         (other than Debt incurred pursuant to this Agreement, the U.S.
         Short-Term Revolving Credit Agreement or the U.S. Long-Term Revolving
         Credit Agreement or any replacement therefor), shall not exceed the sum
         of unused commitments under this Agreement, the U.S. Short-Term
         Revolving Credit Agreement and the U.S. Long-Term Revolving Credit

         banks or other financial institutions; and

                  (2) with respect to any such Debt created or assumed by a
         consolidated Subsidiary that is either a Subsidiary of Parent as of the
         Original Effective Date or a Subsidiary of Parent acquired or created
         after the Original Effective Date and owning a material portion of the
         consolidated operating assets existing at the Original Effective Date
         of Parent and its Subsidiaries, the aggregate amount of Debt of the
         consolidated Subsidiaries of Parent referred to above in this paragraph
         (2) owing to Persons other than Parent and its consolidated
         Subsidiaries is less than the greater of (i) U.S.$500,000,000
         (exclusive of public Debt of LL&E existing at the time LL&E became a
         Subsidiary, the principal amount of which at such time was
         approximately U.S.$400,000,000, and any refinancing of such Debt, in a
         principal amount not to exceed the principal amount refinanced) and
         (ii) 30% of Consolidated Tangible Net Worth as at the date of

                  (c) SALE, ETC. OF ASSETS. Sell, lease or otherwise transfer,
or permit any Material Subsidiary to sell, lease or otherwise transfer (in
either case, whether in one transaction or in a series of transactions, and

direct or indirect Equity Interests in the transferor immediately prior thereto,
and except as permitted by Section 5.02(d)), assets constituting all or
substantially all of the consolidated assets of Parent and its Material
Subsidiaries, provided that, notwithstanding the foregoing, Parent or any
Material Subsidiary may sell, lease or otherwise transfer any Permitted Assets
constituting all or substantially all of the consolidated assets of Parent and
its Material Subsidiaries, so long as (A) such Permitted Assets are sold, leased
or otherwise transferred in exchange for other Permitted Assets and/or (B) the
proceeds from such sale, lease or other transfer, or an amount equal to the

(y) used to repay Debt the proceeds of which were or are being used for
investment in, and/or the development of, Permitted Assets; provided further
that, no such sale, lease or other transfer shall be permitted by the foregoing
proviso unless either (1) after giving effect to such sale, lease or other
transfer, no Event of Default, and no event which with lapse of time or the

         successor is the Borrower or Parent, as applicable, or (ii) in the case
         of an amalgamation involving the Borrower under the laws of Canada or
         any province thereof, the continuing corporation resulting from such
         amalgamation is organized and existing under the laws of Canada or a
         province thereof and continues by operation of law to be liable for all
         obligations of the Borrower under this Agreement and under the Notes,
         provided that notice thereof and a copy of the amalgamation documents
         are provided to the Administrative Agent, or (iii) each successor or
         surviving Business Entity is organized and existing under the laws of
         Canada or a province thereof or the United States or a state thereof,
         respectively, and expressly assumes the obligations of the Borrower or
         Parent, as applicable, hereunder and under the Notes, (B) if any such
         Subsidiary merges, amalgamates or consolidates with (or liquidates
         into) any other Subsidiary of Parent, one or more Business Entities

         amalgamation or consolidation is on an arm's length basis and (C) as a
         result of such merger, amalgamation or consolidation, no Event of
         Default, and no event which with lapse of time or the giving of notice,
         or both, would constitute an Event of Default, shall have occurred and

not pay its debts as such debts become due; or (B) admit in writing its

Worth at such time shall be rendered against Parent or any Material Subsidiary
and either (i) enforcement proceedings shall have been commenced and are
continuing or have been completed by any creditor upon such judgment or order
(other than any enforcement proceedings consisting of the mere obtaining and
filing of a judgment lien or obtaining of a garnishment or similar order so long
as no foreclosure, levy or similar process in respect of such lien, or payment
over in respect of such garnishment or similar order, has commenced and is
continuing or has been completed) or (ii) there shall be any period of 30
consecutive days during which a stay of execution or enforcement proceedings

(ii) of the definition of Termination Event shall have occurred and then exist,
the liability related thereto), in each case in respect of which Parent or any
ERISA Affiliate has liability, is equal to or greater than U.S.$50,000,000; or

                  (h) Parent or any ERISA Affiliate shall have been notified by

U.S.$50,000,000; or

                  (i) Parent or any ERISA Affiliate shall have been notified by
the sponsor of a Multiemployer Plan that such Multiemployer Plan is in
reorganization or is being terminated, within the meaning of Title IV of ERISA,
if as a result of such reorganization or termination the aggregate annual

Plans which are then in reorganization or being terminated have been or will be
increased over the amounts contributed to such Multiemployer Plans for the
respective plan years which include the Original Effective Date by an amount
exceeding U.S.$50,000,000; or

                  (j) Upon completion of, and pursuant to, a transaction, or a
series of transactions (which may include prior acquisitions of capital stock of

other than Parent, a Subsidiary of Parent or any employee benefit plan
maintained for employees of Parent and/or any of its respective Subsidiaries or
the trustee therefor, shall have acquired direct or indirect ownership of and
paid for in excess of 50% of the outstanding capital stock of Parent entitled to
vote in elections for directors of Parent and (ii) at any time before the later

wholly-owned Subsidiary of the Parent; or

                  (l) The Guaranty of Parent hereunder shall not be (or shall be
claimed by Parent, Borrower or any Subsidiary of Parent not to be) valid or in
full force and effect; provided that if within one Business Day after the
Borrower or Parent receives notice from the Administrative Agent or otherwise
becomes aware that such Guaranty is not valid or in full force and effect,
Parent delivers written notice to the Administrative Agent that it intends to
deliver a


                                       57


valid and effective Guaranty, or to reinstate such Guaranty, as soon as
possible, then an Event of Default shall not exist pursuant this Section 6.01(l)
unless Parent shall fail to deliver or reinstate a Guaranty having substantially
the same effect as the Guaranty set forth in Article 8 within four Business Days
after the delivery of such written notice of intent.

                  (m) Any "Event of Default" as defined in the U.S. Short-Term
Revolving Credit Agreement or the U.S. Long-Term Revolving Credit Agreement
shall occur and be continuing;

                  then, and in any such event, the Administrative Agent shall at
the request, or may with the consent, of the Majority Lenders, by notice to the
Borrower and Parent, (i) declare the obligation of each Lender to make Advances
to be terminated, whereupon the same shall forthwith terminate, and (ii) declare
the Advances, all interest thereon and all other amounts payable under this
Agreement to be forthwith due and payable, whereupon the Advances, all such
interest and all such amounts shall become and 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 and Parent; provided, however, that
if an Event of Default under subsection (e) of this Section 6.01 (except under
clause (i)(A) thereof) shall occur, (A) the obligation of each Lender to make
Advances shall automatically be terminated and (B) the Advances, all interest
thereon and all other amounts payable under this Agreement shall automatically
become and be forthwith due and payable, without presentment, demand, protest or
any notice of any kind, all of which are hereby expressly waived by the Borrower
and Parent.

                                   ARTICLE 7

                            THE ADMINISTRATIVE AGENT

                  SECTION 7.01. AUTHORIZATION AND ACTION. Each Lender hereby
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement as are delegated to
the Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including enforcement of this Agreement or collection of the
Notes), the 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 protected in so acting or refraining from acting)
upon the instructions of the Majority Lenders, and such instructions shall be
binding upon all Lenders and all holders of Notes; provided, however, that the
Administrative Agent shall not be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement or applicable law. The Administrative Agent agrees to give to each
Lender prompt notice of each notice given to it by the Borrower pursuant to the
terms of this Agreement. Nothing in this Agreement shall impose upon any
Co-Syndication Agent or Co-Documentation Agent, in its capacity as such, any
duty or liability whatsoever.

                  SECTION 7.02. ADMINISTRATIVE AGENT'S RELIANCE, ETC. Neither
the Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with this Agreement, except for its or their own gross
negligence or willful misconduct. Without limitation of the

                                       58


generality of the foregoing, the Administrative Agent: (i) may treat the payee
of any Note as the holder thereof until the Administrative Agent receives and
accepts an Assignment and Acceptance entered into by the Lender which is the
payee of such Note, as assignor, and an Eligible Assignee, as assignee, as
provided in Section 9.07; (ii) may consult with legal counsel (including counsel
for the Borrower and Parent), independent public accountants and other experts
selected by it and shall not be liable for any action taken or omitted to be
taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (iii) makes no warranty or representation to any Lender
and shall not be responsible to any Lender for any statements, warranties or
representations (whether written or oral) made in or in connection with this
Agreement; (iv) 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 on the part of the Borrower and Parent or to inspect the property
(including the books and records) of the Borrower or Parent; (v) shall not be
responsible to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement or any other
instrument or document furnished pursuant hereto; and (vi) shall incur no
liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by facsimile,
electronic mail, telegram, telecopy, cable or telex) believed by it to be
genuine and signed or sent by the proper party or parties.

                  SECTION 7.03. ADMINISTRATIVE AGENT AND AFFILIATES. With
respect to its Commitments, the Advances made by it and the Notes issued to it,
the Administrative Agent shall have the same rights and powers under this
Agreement as any other Lender and may exercise the same as though it were not
the Administrative Agent; and the term "Lender" or "Lenders" shall, unless
otherwise expressly indicated, include the Administrative Agent in its
individual capacity. The Administrative Agent and its Affiliates may accept
deposits from, lend money to, act as trustee under indentures of, and generally
engage in any kind of business with, Parent, the Borrower, any of their
Subsidiaries, and any Person who may do business with or own securities of
Parent, the Borrower or any of their Subsidiaries, all as if the Administrative
Agent were not the Administrative Agent and without any duty to account therefor
to the other Lenders.

                  SECTION 7.04. LENDER CREDIT DECISION. Each Lender acknowledges
that it has, independently and without reliance upon the Administrative Agent or
any other Lender and based on the financial statements referred to in Section
4.01 and such other documents and information as it has deemed appropriate, made
its own credit analysis and decision to enter into this Agreement. Each Lender
also acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement.

                  SECTION 7.05. INDEMNIFICATION. THE LENDERS AGREE TO INDEMNIFY
THE ADMINISTRATIVE AGENT (TO THE EXTENT NOT REIMBURSED BY THE BORROWER OR
PARENT), RATABLY ACCORDING TO THE RESPECTIVE PRINCIPAL AMOUNTS OF THE ADVANCES
THEN HELD BY EACH OF THEM (OR IF NO ADVANCES ARE AT THE TIME OUTSTANDING OR IF
ANY ADVANCES ARE HELD BY PERSONS WHICH ARE NOT LENDERS, RATABLY ACCORDING TO THE
RESPECTIVE AMOUNTS OF THEIR COMMITMENTS OR THE RESPECTIVE AMOUNTS




                                       59


OF THEIR COMMITMENTS IMMEDIATELY PRIOR TO TERMINATION IF THE COMMITMENTS HAVE
BEEN TERMINATED), FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS
OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY, OR
ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN ANY WAY RELATING TO OR ARISING OUT
OF THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER FINANCING DOCUMENT OR OTHER
INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO OR IN CONNECTION HEREWITH, OR
ANY ACTION TAKEN OR OMITTED BY THE ADMINISTRATIVE AGENT UNDER THIS AGREEMENT, OR
ANY OF THE NOTES OR ANY OTHER FINANCING DOCUMENT OR OTHER INSTRUMENT OR DOCUMENT
FURNISHED PURSUANT HERETO OR IN CONNECTION HEREWITH; 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 ADMINISTRATIVE AGENT'S GROSS NEGLIGENCE OR WILFUL MISCONDUCT.

                  Without limitation of the foregoing, each Lender agrees to
reimburse the Administrative Agent promptly upon demand for such Lender's
ratable share of any reasonable out-of-pocket expenses (including counsel fees)
incurred by the Administrative Agent in connection with the preparation,
execution, delivery, administration, modification, amendment or enforcement
(whether through negotiations, legal proceedings, in bankruptcy or insolvency
proceedings, or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any of the Notes or any other instrument
or document furnished pursuant hereto or in connection herewith to the extent
that the Administrative Agent acts in its capacity as Administrative Agent and
is not reimbursed for such expenses by the Borrower or Parent.

                  SECTION 7.06. SUCCESSOR ADMINISTRATIVE AGENT. The
Administrative Agent may resign at any time by giving written notice thereof to
the Lenders, the Borrower and Parent and may be removed at any time with or
without cause by the Majority Lenders. Upon any such resignation or removal, the
Majority Lenders shall have the right to appoint a successor Administrative
Agent. If no successor Administrative Agent shall have been so appointed by the
Majority Lenders, and shall have accepted such appointment, within 30 days after
the retiring Administrative Agent's giving of notice of resignation or the
Majority Lenders' removal of the retiring Administrative Agent, then such
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a bank organized, or authorized to conduct
a banking business, under the federal laws of Canada and having a combined
capital and surplus of at least U.S.$500,000,000. 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 its duties and obligations under this Agreement. After any retiring
Administrative Agent's resignation or removal hereunder as Administrative Agent,
the provisions of this Article 7 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement.

                                   ARTICLE 8

                                   GUARANTY

                  In order to induce the Lenders to extend credit hereunder,
Parent hereby irrevocably and unconditionally guarantees the Obligations. Parent
agrees that the Guaranteed Parties may make a claim under Parent's guarantee
immediately upon the occurrence of an Event of Default or at any time
thereafter, but (other than in the case of an Event of Default in respect of the
Borrower under Section 6.01(e) (except clause (i)(A) thereof)) following the
making of a demand on the Borrower for payment or performance, as applicable,
without any obligation to first seek any other remedy or take any other action
against the Borrower. Parent further agrees that the due and punctual payment of
the Obligations may be extended or renewed, in whole or in part, without notice
to or further assent from it, and that it will remain bound upon its Guaranty
hereunder notwithstanding any such extension or renewal of any Obligation. Each
and every default in payment of the principal of and premium, if any, or
interest on any Obligation shall give rise to a separate cause of action
hereunder, and separate suits may be brought hereunder as each cause of action
arises.

                  Parent waives presentment to, demand of payment from and
protest to the Borrower of any of the Obligations, and also waives notice of
acceptance of its obligations and notice of protest for nonpayment. The
obligations of Parent hereunder shall not be affected by (a) the failure of any
Guaranteed Party to assert any claim or demand or to enforce any right or remedy
against the Borrower or Parent under the provisions of this Agreement, any other
Financing Document or otherwise; (b) any extension or renewal of any of the
Obligations; (c) any rescission, waiver, amendment or modification of, or
release from, any of the terms or provisions of this Agreement or any other
Financing Document or agreement; (d) the failure or delay of any Guaranteed
Party to exercise any right or remedy against any other guarantor of the
Obligations; (e) the failure of any Guaranteed Party to assert any claim or
demand or to enforce any remedy under any Financing Document, any guaranty or
any other agreement or instrument; (f) any default, failure or delay, wilful or
otherwise, in the performance of the Obligations; or (h) any other act, omission
or delay to do any other act which may or might in any manner or to any extent
vary the risk of Parent or otherwise operate as a discharge of Parent as a
matter of law or equity or which would impair or eliminate any right of Parent
to subrogation.

                  Parent further agrees that its agreement hereunder constitutes
a promise of payment when due (whether or not any bankruptcy or similar
proceeding shall have stayed the accrual or collection of any of the Obligations
or operated as a discharge thereof) and not merely of collection, and waives any
right to require that any resort be had by any Guaranteed Party to any balance
of any deposit account or credit on the books of any Guaranteed Party in favor
of any Borrower or any other Person.

                  The obligations of Parent hereunder shall not be subject to
any reduction, limitation, impairment or termination for any reason, and shall
not be subject to any defense or setoff, counterclaim, recoupment or termination
whatsoever, by reason of the invalidity, illegality or unenforceability of the
Obligations, any impossibility in the performance of the Obligations or
otherwise.



                                       61


                  Parent further agrees that its obligations hereunder shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any Obligation is rescinded or must otherwise
be restored by any Guaranteed Party upon the bankruptcy or reorganization of
Borrower or otherwise.

                  In furtherance of the foregoing and not in limitation of any
other right which any Guaranteed Party may have at law or in equity against
Parent by virtue hereof, upon the failure of the Borrower to pay any Obligation
when and as the same shall become due, whether at maturity, by acceleration,
after notice of prepayment or otherwise, Parent hereby promises to and will,
upon receipt of written demand by the Administrative Agent, forthwith pay, or
cause to be paid, to the Administrative Agent for distribution to the Guaranteed
Parties in cash an amount equal to the sum of (i) the unpaid principal amount of
such Obligations then due, (ii) accrued and unpaid interest and fees on such
Obligations and (iii) all other monetary Obligations then due. Parent further
agrees that if payment in respect of any Obligation shall be due in a currency
other than Cdn. Dollars and/or at a place of payment other than Toronto, Ontario
and if, by reason of any Change in Law, disruption of currency or foreign
exchange markets, war or civil disturbance or similar event, payment of such
Obligation in such currency or at such place of payment shall be impossible or,
in the judgment of any Guaranteed Party, not consistent with the protection of
its rights or interests, then, at the election of such Guaranteed Party, Parent
shall make payment of such Obligation in Cdn. Dollars (based upon the applicable
Exchange Rate in effect on the date of payment) and/or in Toronto, Ontario, and
shall indemnify such Guaranteed Party against any losses or expenses that it
shall sustain as a result of such alternative payment.

                  Upon payment in full by Parent of any Obligation, each Lender
shall, in a reasonable manner, assign the amount of such Obligation owed to it
and so paid to Parent, such assignment to be pro tanto to the extent to which
the Obligation in question was discharged by Parent, or make such disposition
thereof as Parent shall direct (all without recourse to any Guaranteed Party and
without any representation or warranty by any Guaranteed Party).

                  Upon payment by Parent of any sums as provided above, all
rights of Parent against the Borrower arising as a result thereof by way of
right of subrogation or otherwise shall in all respects be subordinated and
junior in right of payment to the prior indefeasible payment in full of all the
Obligations owed by the Borrower to the Guaranteed Parties.

                  Nothing shall discharge or satisfy the liability of Parent
hereunder except the full performance and payment of the Obligations.

                  Each reference herein to any Guaranteed Party shall be deemed
to include their or its successors and assigns, in whose favor the provisions of
this Guaranty shall also inure.

                                    ARTICLE 9

                                  MISCELLANEOUS

                  SECTION 9.01. AMENDMENTS, ETC. An amendment or waiver of any
provision of this Agreement, the Notes or any other Financing Document, or a
consent to any departure by the Borrower therefrom, shall be effective against
the Lenders and all holders of the Notes if, but

                                       62


only if, it shall be in writing and signed or consented to in writing by the
Majority Lenders or, where so specified, the Required Lenders (except any
amendment to give effect to increased Commitments and New Lenders, as
contemplated by Section 2.20), and then such a waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no such amendment, waiver or consent shall,
unless in writing and signed by all the Lenders, be effective to: (a) waive any
of the conditions specified in Article 3, (b) except as contemplated by Section
2.20, increase the Commitments of the Lenders or subject the Lenders to any
additional obligations, (c) reduce the principal of, or interest on, the
Advances or any facility fees or utilization fees hereunder, (d) except as
contemplated by Section 2.21, postpone any date fixed for any payment of
principal of, or interest on, the Advances or any facility fees or utilization
fees hereunder, (e) change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Advances, which shall be required for the Lenders
or any of them to take any action under this Agreement, (f) amend Article VIII
or this Section 9.01, or (g) waive any Event of Default pursuant to Section
6.01(l); and, provided further that no amendment, waiver or consent shall,
unless in writing and signed by the Administrative Agent in addition to the
Lenders required herein above to take such action, affect the rights or duties
of the Administrative Agent under this Agreement or any Note.

                  SECTION 9.03. NO WAIVER; REMEDIES. No failure on the part of
any Lender or the Administrative Agent to exercise, and no delay in exercising,
any right hereunder or under any Note shall operate as a waiver thereof; nor
shall any single or partial exercise of any right hereunder or under any Note
preclude any other or further exercise thereof or the exercise of any other
right. The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

                  SECTION 9.04. COSTS AND EXPENSES; INDEMNITY. (a) The Borrower
agrees to pay on demand (i) all reasonable fees and out-of-pocket expenses of
counsel for the Administrative Agent and the Arranger in connection with the
preparation, execution and delivery of this Agreement, the Notes and the other
Financing Documents to be delivered hereunder and with respect to advising the
Administrative Agent and the Arranger as to their respective rights and
responsibilities under this Agreement, (ii) all reasonable costs and expenses
incurred by the Administrative Agent and its Affiliates and the Arranger and
their Affiliates in initially syndicating all or any portion of the Commitments
hereunder, including the related reasonable fees and out-of-pocket expenses of
counsel for the Administrative Agent or its Affiliates and the Arranger and
their Affiliates, travel expenses, duplication and printing costs and courier
and postage fees, and excluding any syndication fees paid to other parties
joining the syndicate and (iii) all out-of-pocket costs and expenses, if any, of
the Administrative Agent and the Arranger and the Lenders (including reasonable
counsel fees and expenses and the allocated costs of in-house counsel), in
connection with the enforcement (whether through negotiations, legal
proceedings, in bankruptcy or insolvency proceedings, or otherwise) of this
Agreement, the Notes and the other Financing Documents to be delivered hereunder
and thereunder.

                  (b) If any payment of principal of, or Continuation of, any
Eurodollar Rate Advance is made by the Borrower to or for the account of a
Lender on any day other than the last day of the Interest Period for such
Advance, as a result of a prepayment pursuant to Section 2.10 or a Continuation
pursuant to Section 2.08(f) or Section 2.09 or due to acceleration of the
maturity of the Advances pursuant to Section 6.01 or due to any other reason
attributable to the Borrower, or if the Borrower shall fail to borrow, Continue
or prepay any Eurodollar Rate Advance on the date specified in any notice
delivered pursuant hereto, the Borrower shall, upon demand by such Lender (with
a copy of such demand to the Administrative Agent), pay to the Administrative
Agent for the account of such Lender any amounts required to compensate such
Lender for any additional losses, costs or expenses which it may reasonably
incur as a result of such payment or Continuation, including any loss (excluding
loss of anticipated profits), cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by any Lender to
fund or maintain such Advance.

                  (c) If any payment of principal of any B/A Advance is made by
the Borrower to or for the account of a Lender on any day other than the last
day of the Interest Period for such Advance, due to acceleration of the maturity
of the Advances pursuant to Section 6.01, or if the Borrower shall fail to
borrow, Continue or prepay any B/A Advance on the date specified in any notice
delivered pursuant hereto, the Borrower shall, upon demand by such Lender (with
a copy of such demand to the Administrative Agent), pay to the Administrative
Agent for the account of such Lender any amounts required to compensate such
Lender for any additional losses, costs or expenses which it may reasonably
incur as a result of such payment, including any loss (excluding loss of
anticipated profits), cost or expense incurred by reason of the liquidation or




                                       64


reemployment of deposits or other funds acquired by any Lender to fund or
maintain such Advance. It is understood that a defeasance of B/A's under Section
2.10(a) shall not constitute a prepayment.

                  (d) EACH OF THE BORROWER AND PARENT AGREES TO INDEMNIFY AND
HOLD HARMLESS THE ADMINISTRATIVE AGENT, THE ARRANGER AND EACH LENDER FROM AND
AGAINST ANY AND ALL CLAIMS, DAMAGES, LIABILITIES AND EXPENSES (INCLUDING FEES
AND DISBURSEMENTS OF COUNSEL) WHICH MAY BE INCURRED BY OR ASSERTED AGAINST THE
ADMINISTRATIVE AGENT, THE ARRANGER OR SUCH LENDER IN CONNECTION WITH OR ARISING
OUT OF ANY INVESTIGATION, LITIGATION, OR PROCEEDING (WHETHER OR NOT THE
ADMINISTRATIVE AGENT, THE ARRANGER OR SUCH LENDER IS PARTY THERETO) RELATED TO
ANY ACQUISITION OR PROPOSED ACQUISITION BY THE BORROWER, OR BY ANY SUBSIDIARY OF
THE BORROWER, OF ALL OR ANY PORTION OF THE EQUITY INTERESTS IN, OR SUBSTANTIALLY
ALL THE ASSETS OF, ANY PERSON OR ANY USE OR PROPOSED USE OF THE ADVANCES BY THE
BORROWER (EXCLUDING ANY CLAIMS, DAMAGES, LIABILITIES OR EXPENSES INCURRED BY
REASON OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PARTY TO BE
INDEMNIFIED OR ITS EMPLOYEES OR ADMINISTRATIVE AGENTS, OR BY REASON OF ANY USE
OR DISCLOSURE OF INFORMATION RELATING TO ANY SUCH ACQUISITION OR USE OR PROPOSED
USE OF THE PROCEEDS BY THE PARTY TO BE INDEMNIFIED OR ITS EMPLOYEES OR
ADMINISTRATIVE AGENTS).

                  SECTION 9.05. RIGHT OF SET-OFF. Upon the declaration of the
Advances as due and payable pursuant to the provisions of Section 6.01, each
Lender is hereby authorized 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
indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower against any and all of the obligations of the Borrower
now or hereafter existing under this Agreement and any Note held by such Lender,
irrespective of whether or not such Lender shall have made any demand under this
Agreement or such Note and although such obligations may be unmatured. Each
Lender agrees promptly to notify the Borrower 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
each Lender under this Section 9.05 are in addition to other rights and remedies
(including other rights of set-off) which such Lender may have.

                  SECTION 9.06. BINDING EFFECT. This Agreement shall become
effective in accordance with the provisions of Section 3.01, and thereafter
shall be binding upon and inure to the benefit of the Borrower, Parent, the
Administrative Agent, the Arranger and each Lender and their respective
successors and assigns, except that neither Parent nor the Borrower shall have
the right to assign its rights and obligations hereunder or any interest herein
without the prior written consent of all of the Lenders; provided that
notwithstanding the foregoing the Borrower shall be permitted to transfer its
rights and obligations hereunder to a wholly-owned Subsidiary of Parent (i) if
such Subsidiary is organized and existing under the laws of Canada or any


                                       65


political subdivision thereof and (ii) Burlington Resources Canada Ltd.
guarantees the obligations of the new Borrower on substantially the same terms
as Parent, at which time Burlington Resources Canada Ltd. shall cease to be a
Borrower hereunder and shall cease to have any liability under this Agreement,
the Notes, if any, or any other Financing Document except such guarantee. Any
merger, amalgamation or consolidation in compliance with Section 5.02(d) of (i)
the Borrower with Parent or a wholly-owned Subsidiary of Parent organized under
the laws of Canada or any political subdivision thereof, or (ii) Parent shall
not constitute an assignment for purposes of this Section 9.06.

                  SECTION 9.07. ASSIGNMENTS AND PARTICIPATIONS. (a) Each Lender
may assign to one or more banks or other entities all or a portion of its rights
and obligations under this Agreement (including all or a portion of its
Commitment, the Advances owing to it and the Note or Notes held by it);
provided, however, that each such assignment shall be to an Eligible Assignee
and the parties to each such assignment shall execute and deliver to the
Administrative Agent, for its acceptance and recording in the Register, an
Assignment and Acceptance, together with any Note or Notes subject to such
assignment and, except in the case of an assignment to a Lender Affiliate, a
processing and recordation fee of Cdn.$3,500, and shall send to the Borrower an
executed counterpart of such Assignment and Acceptance, and provided further,
however, that (i) except in the case of an assignment to a Lender Affiliate,
each such assignment shall be of a constant, and not a varying, percentage of
all such Lender's rights and obligations under this Agreement, (ii) the amount
of the Commitment of the assigning Lender being assigned to the assignee
pursuant to each such assignment (determined as of the date of the Assignment
and Acceptance with respect to such assignment) must be equal to or greater than
Cdn.$10,000,000, or if less, the entire amount of such assigning Lender's
"Commitment" (unless the Borrower and the Administrative Agent shall otherwise
consent, which consent may be withheld for any reason) and must be an integral
multiple of Cdn.$1,000,000, and (iii) except in the case of an assignment by a
Schedule II Lender to a Lender Affiliate thereof that is a Schedule III Bank,
any assignment to a Lender Affiliate will not relieve the assigning Lender of
its obligation to make Advances hereunder timely in accordance with the terms
hereof in the event such Lender Affiliate shall fail to do so. Upon the
execution, delivery, acceptance and recording of each Assignment and Acceptance
by the parties thereto, from and after the effective date specified in such
Assignment and Acceptance, (x) the assignee thereunder shall be a party hereto
and, subject to clause (iii) above, to the extent that rights and obligations
hereunder have been assigned to it pursuant to such Assignment and Acceptance,
have the rights and obligations of a Lender hereunder and (y) except in the
circumstances contemplated in clause (iii) above, the Lender assignor thereunder
shall, to the extent that rights and obligations hereunder have been assigned by
it pursuant to such Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's rights and obligations under this Agreement,
such Lender shall cease to be a party hereto, provided, however, such assigning
Lender shall retain any claim with respect to any fee, interest, cost, expense
or indemnity which accrues, or relates to an event that occurs, prior to the
date of such assignment pursuant to Section 2.03, 2.06, 2.12, 2.13, 2.16 or
9.04)

                  (b) By executing and delivering an Assignment and Acceptance,
each Lender assignor thereunder and the assignee thereunder confirm to and agree
with each other and the other parties hereto as follows: (i) other than as
provided in such Assignment and Acceptance, such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this




                                       66


Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto; (ii) such assigning Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of the Borrower or Parent or the performance or observance by the Borrower or
Parent of any of its obligations under this Agreement or any other instrument or
document furnished pursuant hereto; (iii) such assignee confirms that it has
received a copy of this Agreement, together with copies of the financial
statements referred to in Section 4.01 and such other documents and information
as it has deemed appropriate to make its own credit analysis and decision to
enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Administrative Agent, such assigning
Lender or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee confirms
that it is (subject to approval in writing by the Borrower and the
Administrative Agent to the extent required) an Eligible Assignee; (vi) such
assignee appoints and authorizes the Administrative Agent to take such action as
agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Administrative Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; and (vii) such assignee agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of this Agreement are required to be performed by it as a Lender.

                  (c) The Administrative Agent shall maintain at its address
referred to in Section 9.02 a copy of each Assignment and Acceptance, each New
Lender Agreement and each Commitment Increase Agreement delivered to and
accepted by it and a register (which register may be in electronic form) for the
recordation of the names and addresses of the Lenders and the Commitment of, and
principal amount of the Advances owing to, each Lender from time to time (the
"REGISTER"). The entries in the Register shall be conclusive and binding for all
purposes, absent manifest error, and the Borrower, the Administrative Agent and
the Lenders may treat each Person whose name is recorded in the Register as a
Lender hereunder for all purposes of this Agreement. The Register shall be
available for inspection by the Borrower or any Lender at any reasonable time
and from time to time upon reasonable prior notice.

                  (d) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an assignee representing that it is an Eligible
Assignee, together with any Note or Notes subject to such assignment, the
Administrative Agent shall, if such Assignment and Acceptance has been completed
and is in substantially the form of Exhibit D hereto, (i) accept such Assignment
and Acceptance, (ii) record the information contained therein in the Register
and (iii) give prompt notice thereof to the Borrower. Within five Business Days
after its receipt of such notice and its receipt of an executed counterpart of
such Assignment and Acceptance, the Borrower, at its own expense, shall execute
and deliver to the Administrative Agent in exchange for any surrendered Note or
Notes a new Note to the order of such Eligible Assignee and, if the assigning
Lender has retained a Commitment hereunder, a new Note to the order of the
assigning Lender. Any such new Note or Notes shall be dated the effective date
of such Assignment and Acceptance and shall otherwise be in substantially the
form of Exhibit A hereto.

                  (e) Each Lender may sell participations to one or more banks
or other entities in or to all or a portion of its rights and obligations under
this Agreement (including all or a

                                       67


portion of its Commitment, and the Advances owing to it and the Note or Notes
held by it); provided, however, that (i) such Lender's obligations under this
Agreement (including its Commitment to the Borrower hereunder) shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations, (iii) such Lender shall remain
the holder of any such Note for all purposes of this Agreement, (iv) the
Borrower, the Administrative Agent and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, (v) such Lender shall continue to be able to
agree to any modification or amendment of this Agreement or any waiver hereunder
without the consent, approval or vote of any such participant or group of
participants, other than modifications, amendments and waivers which (A)
postpone any date fixed for any payment of, or reduce any payment of, principal
of or interest on such Lender's Advances or any facility fees or utilization
fees payable under this Agreement, or (B) increase the amount of such Lender's
Commitment in a manner which would have the effect of increasing the amount of a
participant's participation, or (C) reduce the interest rate payable under this
Agreement and such Lender's Advances, or (D) consent to the assignment or the
transfer by the Borrower or Parent of their respective rights and obligations
under the Agreement, and (vi) except as contemplated by the immediately
preceding clause (v), no participant shall be deemed to be or to have any of the
rights or obligations of a "Lender" hereunder.

                  (f) Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.07, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower furnished to such Lender
by or on behalf of the Borrower; provided that, prior to any such disclosure,
the assignee or participant or proposed assignee or participant shall agree in
writing for the benefit of the Borrower to preserve the confidentiality of any
confidential information relating to the Borrower received by it from such
Lender in a manner consistent with Section 9.08.

                  (g) Anything in this Agreement to the contrary
notwithstanding, any Lender may at any time create a security interest in all or
any portion of its rights under this Agreement (including the Advances owing to
it) and the Notes, if any, issued to it hereunder in favor of any United States
Federal Reserve Bank in accordance with Regulation A of the Board of Governors
of the Federal Reserve System of the United States (or any successor regulation)
and the applicable operating circular of such Federal Reserve Bank.

                  SECTION 9.08. CONFIDENTIALITY. Each Lender and the
Administrative Agent (each, a "PARTY") agrees that it will use its best
reasonable efforts not to disclose, without the prior consent of the Borrower
(other than to its, or its Affiliates, employees, auditors, accountants, counsel
or other representatives, whether existing at the Effective Date or any
subsequent time), any information with respect to the Borrower or Parent which
is furnished pursuant to this Agreement, provided that any party may disclose
any such information (i) as has become generally available to the public, (ii)
as may be required or appropriate in any report, statement or testimony
submitted to any governmental authority having or claiming to have jurisdiction
over such party, (iii) as may be required or appropriate in response to any
summons or subpoena or in connection with any litigation or regulatory
proceeding, (iv) in order to comply with any law, order, regulation or ruling
applicable to such party, or (v) to any prospective assignee or

                                       68


participant in connection with any contemplated assignment of any rights or
obligations hereunder or any sale of any participation therein, by such party
pursuant to Section 9.07, if such prospective assignee or participant, as the
case may be, executes an agreement with the Borrower containing provisions
substantially similar to those contained in this Section 9.08; provided,
however, that the Borrower and Parent acknowledge that the Administrative Agent
has disclosed and may continue to disclose such information as the
Administrative Agent in its sole discretion determines is appropriate to the
Lenders from time to time.

                  SECTION 9.09. CONSENT TO JURISDICTION. (a) Each of the
Borrower and Parent hereby irrevocably and unconditionally submit itself and its
property to the non-exclusive jurisdiction of the Courts of the Province of
Alberta in any action or proceeding by the Administrative Agent, the Arranger,
any Lender or the holder of any Note in respect of, but only in respect of, any
claims or causes of action arising out of or relating to this Agreement, the
Notes or the other Financing Documents (such claims and causes of action,
collectively, being "PERMITTED CLAIMS"), and each of the Borrower and Parent
hereby irrevocably agrees that all Permitted Claims may be heard and determined
in Alberta. Each of the Borrower and Parent hereby irrevocably and
unconditionally waives, to the fullest extent it may effectively do so, the
defense of an inconvenient forum to the maintenance of such action or proceeding
in any aforementioned court in respect of Permitted Claims. Service of the
statement of claim and any other process which may be served by the
Administrative Agent, the Arranger, any Lender or the holder of any Note on the
Borrower or Parent in any such action or proceeding in any aforementioned court
in respect of Permitted Claims may be made by delivering separate copies of such
process to each of the Borrower and Parent by courier and by registered mail
(return receipt requested), fees and postage prepaid at the address of each of
the Borrower and Parent specified pursuant to Section 9.02, to the attention of
each of the Treasurer and the Vice President and General Counsel of Parent, or
each of the General Counsel and Assistant Treasurer in the case of the Borrower.
Each of the Borrower and Parent 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.

                  (b) Nothing in this Section 9.09 (i) shall affect the right of
the Arranger, the Borrower, Parent, any Lender, the holder of any Note or the
Administrative Agent to serve legal process in any other manner permitted by law
or affect any right otherwise existing of the Borrower, any Lender, the
Arranger, the holder of any Note or the Administrative Agent to bring any action

    The applicable pricing level shall change on the date of any relevant change
    in the rating by S&P or Moody's of any public long term senior unsecured
    debt securities of the Borrower. In the case of split ratings from S&P and
    Moody's, the rating to be used to determine the applicable pricing level is
    the higher of the two (e.g., A-/Baa1 results in Level II pricing), provided
    that in the event the split is more than one full category, the average (or
    the higher of two intermediate ratings) shall be used (e.g., A-/Baa2 results
    in Level III pricing, as does A-/Baa3). For the avoidance of doubt, the
    amount to be paid with respect to any Acceptance Fee shall be determined on
    the date of the acceptance of the applicable B/A, and the Acceptance Fee
    paid on each date shall not be subject to adjustment based on a subsequent
    change in the pricing level.
