                                   ARTICLE IV.

                         Representations and Warranties

      Section 4.1. Representations and Warranties of US Borrower. In order to
induce the US Lenders to enter into this Amendment, US Borrower represents and
warrants to each US Lender that:

      (a) The representations and warranties contained in Article V of the
Restated Agreement are true and correct at and as of the time of the
effectiveness hereof, except to the extent that the facts on which such
representations and warranties are based have been changed by the extension of
credit under the US Agreement.

      (b) US Borrower is duly authorized to execute and deliver this Amendment
and is and will continue to be duly authorized to borrow monies and to perform
its obligations under the US Agreement. US Borrower has duly taken all corporate
action necessary to authorize the execution and delivery of this Amendment and
to authorize the performance of the obligations of US Borrower hereunder.

      (c) The execution and delivery by US Borrower of this Amendment, the
performance by US Borrower of its obligations hereunder and the consummation of
the transactions contemplated hereby do not and will not (i) conflict with any
provision of (A) any Law, (B) the organizational documents of US Borrower, or
(C) any agreement, judgment, license, order or permit applicable to or binding
upon US Borrower unless such conflict would not reasonably be expected to have a
Material Adverse Effect, or (ii) result in or require the creation of any Lien
upon any assets or properties of US Borrower which would reasonably be expected
to have a Material Adverse Effect, except as expressly contemplated or permitted
in the Loan Documents. Except as expressly contemplated in the Loan Documents no
consent, approval, authorization or order of, and no notice to or filing with,
any Tribunal or third party is required in connection with the execution,
delivery or performance by US Borrower of this Amendment or to consummate any
transactions contemplated by this Amendment, unless failure to obtain such
consent would not reasonably be expected to have a Material Adverse Effect.

      (d) When duly executed and delivered, each of this Amendment and the US
Agreement will be a legal and binding obligation of US Borrower, enforceable in
accordance with its terms, except as limited by bankruptcy, insolvency or
similar laws of general application relating to the enforcement of creditors'
rights and by equitable principles of general application.

      (e) The audited annual Consolidated financial statements of US Borrower
dated as of December 31, 2001 and the unaudited quarterly Consolidated financial
statements of US Borrower dated as of March 31, 2002 fairly present the
Consolidated financial position at such dates and the Consolidated statement of
operations and the changes in Consolidated financial position for the periods
ending on such dates for US Borrower. Copies of such financial statements have
heretofore been delivered to each US Lender. Since such dates no material

                                       4

adverse change has occurred in the Consolidated financial condition or
businesses of US Borrower.

                                   ARTICLE V.

                                  Miscellaneous

amended and restated and the Tranche A Notes are hereby ratified and confirmed
in all respects. The US Loan Documents, as they may be amended or affected by
this Amendment, are hereby ratified and confirmed in all respects. Any reference
to the US Agreement in any Loan Document shall be deemed to be a reference to
the Original Agreement as hereby amended and restated. The execution, delivery
and effectiveness of this Amendment shall not, except as expressly provided
herein, operate as a waiver of any right, power or remedy of US Lenders under
the US Agreement or any other US Loan Document nor constitute a waiver of any
provision of the US Agreement or any other US Loan Document.

      Section 5.2. Survival of Agreements. All representations, warranties,
covenants and agreements of US Borrower herein shall survive the execution and
delivery of this Amendment and the performance hereof, including without
limitation the making or granting of the Loans, and shall further survive until
all of the Obligations are paid in full. All statements and agreements contained
in any certificate or instrument delivered by US Borrower or any Restricted
Person hereunder or under the US Agreement to any US Lender shall be deemed to
constitute representations and warranties by, and/or agreements and covenants
of, US Borrower under this Amendment and under the US Agreement.

      Section 5.3. US Loan Documents. This Amendment is a US Loan Document, and
all provisions in the US Agreement pertaining to US Loan Documents apply hereto.

      Section 5.4. Governing Law. This Amendment shall be governed by and
construed in accordance the laws of the State of Texas and any applicable laws
of the United States of America in all respects, including construction,
validity and performance.

      Section 5.5. Counterparts; Fax. This Amendment may be separately executed
in counterparts and by the different parties hereto in separate counterparts,
each of which when so executed shall be deemed to constitute one and the same
Amendment. This Amendment may be validly executed by facsimile or other
electronic transmission.

      THIS AMENDMENT AND THE OTHER US LOAN DOCUMENTS REPRESENT THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS OF THE PARTIES.

                    AMENDED AND RESTATED US CREDIT AGREEMENT

      THIS AMENDED AND RESTATED US CREDIT AGREEMENT (this "Agreement") is made
as of June 7, 2002, by and among Devon Energy Corporation, a Delaware
corporation (herein called "US Borrower"), Bank of America, N.A., individually
and as administrative agent (herein called "US Agent"), and the Lenders party
to, and as defined under, the Existing US Credit Agreement (as defined below).

      US Borrower, US Agent and US Lenders entered into the US Credit Agreement
dated as of August 29, 2000 (as amended, supplemented or otherwise modified
prior to the Closing Date as defined herein, the "Existing US Credit
Agreement"), for the purpose and consideration therein expressed, wherein US
Lenders became obligated to make loans to US Borrower as therein provided.

      US Borrower has requested that Tranche B Lenders extend the effectiveness
of the Tranche B Revolving Period as set forth in the Existing US Credit
Agreement and make certain other amendments and modifications thereto, all on
the terms and conditions provided herein and in the Seventh Amendment to US
Credit Agreement to which this Amended and Restated Credit Agreement is attached
(the "Seventh Amendment to US Credit Agreement").

      US Agent and Tranche B Required Lenders under the Existing US Credit
Agreement have consented to make such extension and the US Required Lenders
under the Existing US Credit Agreement have consented to such other amendments
effective pursuant to the Seventh Amendment to US Credit Agreement. Accordingly,
in consideration of the loans which may hereafter be made by US Lenders to US
Borrower, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, US Borrower, US Agent and US
Lenders hereby agree as follows:

                            ARTICLE I - The US Loans

      Section 1.1. Commitments to Lend; US Notes.

      (a) Tranche A. Subject to the terms and conditions hereof, each Tranche A
Lender agrees (i) that as of the Closing Date, each Tranche A Loan as defined in
and outstanding under the Existing US Credit Agreement will be continued
automatically as a Tranche A Loan hereunder and (ii) to make loans to US
Borrower (herein called such Tranche A Lender's "Tranche A Loans") upon US
Borrower's request from time to time during the Tranche A Commitment Period,
provided that (i) subject to Sections 3.3, 3.4 and 3.5, all Tranche A Lenders
are requested to make Tranche A Loans of the same Type in accordance with their
respective Tranche A Percentage Shares and as part of the same Borrowing, (ii)
such Tranche A Lender's Tranche A Percentage Share of the Tranche A Facility
Usage shall never exceed such Tranche A Lender's Percentage Share of the Tranche
A Maximum Credit Amount, (iii) such Tranche A Lender's

<PAGE>

Percentage Share of the US Facility Usage shall never exceed such Tranche A
Lender's Percentage Share of the US Maximum Credit Amount, and (iv) the
aggregate amount of the Tranche A Facility Usage and the US Swing Loans
outstanding shall never exceed the Tranche A Maximum Credit Amount. The
aggregate amount of all Tranche A Loans in any Borrowing must be an integral
multiple of US $100,000 which equals or exceeds US $200,000 or must equal the
unadvanced portion of the US Maximum Credit Amount. The obligation of US
Borrower to repay to each Tranche A Lender the aggregate amount of all Tranche A
Loans made by such Tranche A Lender, together with interest accruing in
connection therewith, shall be evidenced by a single promissory note (herein
called such Tranche A Lender's "Tranche A Note") made by US Borrower payable to
the order of such Tranche A Lender in the form of Exhibit A-1 with appropriate
insertions and issued under the Existing US Agreement. The amount of principal
owing on any Tranche A Lender's Tranche A Note at any given time shall be the
aggregate amount of all Tranche A Loans theretofore made by such Tranche A
Lender minus all payments of principal theretofore received by such Tranche A
Lender on such Tranche A Note. Interest on each Tranche A Note shall accrue and
be due and payable as provided herein and therein. Each Tranche A Note shall be
due and payable as provided herein and therein, and shall be due and payable in

      (b) Tranche B. Subject to the terms and conditions hereof, each Tranche B
Lender agrees to make loans to US Borrower (herein called such Tranche B
Lender's "Tranche B Loans") upon US Borrower's request from time to time during
the Tranche B Revolving Period, provided that (i) subject to Sections 3.3, 3.4
and 3.5, all Tranche B Lenders are requested to make Tranche B Loans of the same
Type in accordance with their respective Tranche B Percentage Shares and as part
of the same Borrowing, (ii) such Tranche B Lender's Tranche B Percentage Share
of the Tranche B Facility Usage shall never exceed such Tranche B Lender's
Tranche B Percentage Share of the Tranche B Maximum Credit Amount, and (iii)
such Tranche B Lender's Percentage Share of the US Facility Usage shall never
exceed such Tranche B Lender's Percentage Share of the US Maximum Credit Amount.
The aggregate amount of all Tranche B Loans in any Borrowing must be an integral
multiple of US $100,000 which equals or exceeds US $200,000 or must equal the
unadvanced portion of the US Maximum Credit Amount. The obligation of US
Borrower to repay to each Tranche B Lender the aggregate amount of all Tranche B
Loans made by such Tranche B Lender, together with interest accruing in
connection therewith, shall be evidenced by a single promissory note (herein
called such Tranche B Lender's "Tranche B Note") made by US Borrower payable to
the order of such Tranche B Lender in the form of Exhibit A-2 with appropriate
insertions. The amount of principal owing on any Tranche B Lender's Tranche B
Note at any given time shall be the aggregate amount of all Tranche B Loans
theretofore made by such Tranche B Lender minus all payments of principal
theretofore received by such Tranche B Lender on such Tranche B Note. Interest
on each Tranche B Note shall accrue and be due and payable as provided herein
and therein. Each Tranche B Note shall be due and payable as provided herein and

Subject to the terms and conditions hereof, US Borrower may borrow, repay, and
reborrow Tranche B Loans under the US Agreement during the Tranche B Revolving

Borrower may have no more than ten Borrowings of US Dollar Eurodollar Loans
(including Tranche A Loans and Tranche B Loans) outstanding at any time.

      (c)   Extension of Conversion Date.

            (i) US Borrower may, at its option and from time to time during the
      Tranche B Revolving Period, request an offer to extend the Tranche B
      Revolving Period by delivering to US Agent a Request for an Offer of
      Extension not more than sixty days and not less than thirty days prior to
      the then current Tranche B Conversion Date. US Agent shall forthwith
      provide a copy of the Request for an Offer of Extension to each of the
      Tranche B Lenders. Upon receipt from US Agent of an executed Request for
      an Offer of Extension, each Tranche B Lender shall, within twenty days
      after the date of such Tranche B Lender's receipt of such request from US
      Agent, either:

                  (1) notify US Agent of its acceptance of the Request for an
            Offer of Extension, and the terms and conditions, if any, upon which
            such Tranche B Lender is prepared to extend the Tranche B Conversion
            Date; or

                  (2) notify US Agent that the Request for an Offer of Extension
            has been denied, such notice to forthwith be forwarded by US Agent
            to US Borrower to allow US Borrower to seek a replacement lender
            pursuant to Section 1.1(e) (any Tranche B Lender giving notice of
            such denial is herein called a "Non-Accepting Lender"). The failure
            of a Tranche B Lender to so notify US Agent within such twenty day
            period shall be deemed to be notification by such Tranche B Lender
            to US Agent that such Tranche B Lender has denied US Borrower's
            Request for an Offer of Extension.

            (ii) Provided that all Tranche B Lenders provide notice to US Agent
      under Section 1.1(c)(i) that they accept the Request for an Offer of
      Extension, or if there are Non-Accepting Lenders, such Tranche B Lenders
      shall have been repaid pursuant to Section 1.1(e) or replacement lenders
      shall have become parties hereto pursuant to Section 1.1(e) and shall have
      accepted the Request for an Offer of Extension, such acceptance having
      common terms and conditions, US Agent shall deliver to US Borrower an
      Offer of Extension incorporating the said terms and conditions. Such offer
      shall be open for acceptance by US Borrower until the fifth Business Day
      immediately preceding the then current Tranche B Conversion Date. Upon
      written notice by US Borrower to US Agent accepting an outstanding Offer
      of Extension and agreeing to the terms and conditions, if any, specified
      therein (the date of such notice of acceptance in this Section 1.1 being
      called the "Extension Date"), the Tranche B Conversion Date shall be
      extended to the date 364 days from the Extension Date and the terms and
      conditions specified in such Offer of Extension shall be immediately
      effective.

            (iii) US Borrower understands that the consideration of any Request
      for an Offer of Extension constitutes an independent credit decision which
      each Tranche B Lender retains the absolute and unfettered discretion to
      make and that no commitment in

                                       3
<PAGE>

      this regard is hereby given by a Tranche B Lender and that any offer to
      extend the Tranche B Conversion Date may be on such terms and conditions
      in addition to those set out herein as the extending Tranche B Lenders
      stipulate.

      (d) Conversion to Tranche B Term Loan. Effective at 11:59 p.m. Dallas,
Texas time on the day immediately preceding the Tranche B Conversion Date, (i)
each Tranche B Lender's obligation to make new Tranche B Loans shall be canceled
automatically, and (ii) each Tranche B Lender's Tranche B Loans shall become
term loans maturing on the Tranche B Maturity Date.

      (e) Non-Accepting Lender. Provided that Tranche B Required Lenders provide
notice to US Agent under Section 1.1(c)(i) that they accept the Request for an
Offer of Extension, on notice of US Borrower to US Agent, US Borrower shall be
entitled to choose any of the following in respect of each Non-Accepting Lender
prior to the expiration of the Tranche B Revolving Period, provided that if US
Borrower does not make an election prior to the expiration of the Tranche B
Revolving Period, US Borrower shall be deemed to have irrevocably elected to
exercise the provisions of Section 1.1(e)(i):

            (i) the Non-Accepting Lender's obligations to make Tranche B Loans
      and Canadian Loans shall be canceled as of the Extension Date, the Tranche
      B Maximum Credit Amount and the Canadian Maximum Credit Amount shall be
      reduced by the amount so canceled, and on or prior to the Extension Date
      US Borrower shall repay in full all Tranche B Loans and all Canadian
      Obligations then outstanding to the Non-Accepting Lender (as defined in
      Section 1.1(c)(i)(2)), or

            (ii) replace the Non-Accepting Lender by reaching satisfactory
      arrangements with one or more existing Lenders or new Lenders, for the
      purchase, assignment and assumption of the Tranche B Loans and the
      Canadian Obligations of the Non-Accepting Lender, and the related rights
      and obligations of such Non-Accepting Lender under the Loan Documents,
      provided that any new Tranche B Lender, with, if necessary, any Affiliate,
      shall take a pro rata assignment of such Tranche B Loans, Canadian
      Obligations and related rights and obligations, and such Non-Accepting
      Lender shall be obligated to sell such Obligations in accordance with such
      satisfactory arrangements.

      In connection with any such replacement of a Tranche B Lender pursuant to
      this Section 1.1(e), US Borrower shall pay all costs that would have been
      due to such Tranche B Lender pursuant to Section 3.6 if such Tranche B
      Lender's US Loans had been prepaid at the time of such replacement.

      (f) Swing Loans. Subject to the terms and conditions hereof, US Agent
agrees (i) that as of the Closing Date, each US Swing Loan as defined in and
outstanding under the Existing US Credit Agreement will be continued
automatically as a US Swing Loan hereunder and (ii) to make loans to US Borrower
(herein called "US Swing Loans") upon US Borrower's request from time to time
during the Tranche A Commitment Period, provided that (i) the aggregate amount
of US Swing Loans outstanding shall never exceed the US Swing Sublimit, (ii) the
aggregate amount of Tranche A Facility Usage and US Swing Loans outstanding
shall never exceed the Tranche A

                                       4
<PAGE>

Maximum Credit Amount, and (iii) the US Facility Usage shall never exceed the US
Maximum Credit Amount. The aggregate amount of all US Swing Loans in any
Borrowing must be an integral multiple of US $100,000 which equals or exceeds US
$1,000,000 or must equal the unadvanced portion of the Tranche A Maximum Credit
Amount. The obligation of US Borrower to repay to US Agent the aggregate amount
of all US Swing Loans made by US Agent, together with interest accruing in
connection therewith, shall be evidenced by a single promissory note (herein
called the "US Swing Note") made by US Borrower payable to the order of US Agent
in the form of Exhibit A-3 and issued under the Existing US Credit Agreement.
The amount of principal owing on the US Swing Note at any given time shall be
the aggregate amount of all US Swing Loans theretofore made by US Agent minus
all payments of principal theretofore received by US Agent on the US Swing Note
(including as a result of any refinancing pursuant to Section 1.8). Interest on
the US Swing Note shall accrue and be due and payable as provided herein and
therein. The US Swing Note shall be due and payable as provided herein and
therein, and shall be due and payable in full on the Tranche A Maturity Date.
Subject to the terms and conditions hereof, US Borrower may borrow, repay, and
reborrow US Swing Loans under the US Agreement during the Tranche A Commitment
Period.

      Section 1.2. Requests for New US Loans. US Borrower must give to US Agent
written notice (or telephonic notice promptly confirmed in writing) of any
requested Borrowing of new US Loans to be advanced by Lenders. Each such notice
constitutes a "Borrowing Notice" hereunder and must:

      (a) specify the aggregate amount of any such Borrowing of new US Base Rate
Loans and the date on which such US Base Rate Loans are to be advanced, the
aggregate amount of any such Borrowing of new US Dollar Eurodollar Loans, the
date on which such US Dollar Eurodollar Loans are to be advanced (which shall be
the first day of the Eurodollar Interest Period which is to apply thereto), and
the length of the applicable Eurodollar Interest Period, or the aggregate amount
of any such Borrowing of new US Swing Loans and the date on which such US Swing
Loans are to be advanced; and

      (b) be received by US Agent (i) in the case of US Loans that are not US
Swing Loans, not later than 11:00 a.m., Dallas, Texas time, on the day on which
any such US Base Rate Loans are to be made, or the second Business Day preceding
the day on which any such US Dollar Eurodollar Loans are to be made, and (ii) in
the case of US Loans that are US Swing Loans, not later than 4:00 p.m., Dallas,
Texas time on the Business Day on which any such US Swing Loans are to be made.

Each such written request or confirmation must be made in the form and substance
of the "Borrowing Notice" attached hereto as Exhibit B, duly completed. Each
such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by US Borrower as to the matters which are required
to be set out in such written confirmation. Upon receipt of any such Borrowing
Notice, US Agent shall give each Lender notice of the terms thereof (excluding
US Swing Loans) not later than 2:00 p.m., Dallas, Texas time on the day it
receives such Borrowing Notice from US Borrower if it receives such Borrowing
Notice by 11:00 a.m., Dallas, Texas time, otherwise on the next Business Day. If
all conditions precedent to such new US

                                       5
<PAGE>

Loans have been met, each Lender will on the date requested promptly remit to US
Agent at US Agent's office in Dallas, Texas the amount of such Lender's new US
Loan in immediately available funds, and upon receipt of such funds, unless to
its actual knowledge any conditions precedent to such US Loans have been neither
met nor waived as provided herein, US Agent shall promptly make such US Loans
available to US Borrower. Unless US Agent shall have received prompt notice from
a Lender that such Lender will not make available to US Agent such Lender's new
US Loan, US Agent may in its discretion assume that such Lender has made such US
Loan available to US Agent in accordance with this section and US Agent may if
it chooses, in reliance upon such assumption, make such US Loan available to US
Borrower. If and to the extent such Lender shall not so make its new US Loan
available to US Agent, such Lender and US Borrower severally agree to pay or
repay to US Agent within three days after demand the amount of such US Loan
together with interest thereon, for each day from the date such amount was made
available to US Borrower until the date such amount is paid or repaid to US
Agent, with interest at (1) the Federal Funds Rate, if such Lender is making
such payment; provided that US Agent gave notice of the terms of the Borrowing
Notice to such Lender in accordance with the terms of this Section 1.2, and (2)
the interest rate applicable at the time to the other new US Loans made on such
date, if US Borrower is making such repayment. If neither such Lender nor US
Borrower pays or repays to US Agent such amount within such three-day period, US
Agent shall in addition to such amount be entitled to recover from such Lender
and from US Borrower, on demand, interest thereon at the Default Rate for US
Base Rate Loans, calculated from the date such amount was made available to US
Borrower. The failure of any Lender to make any new US Loan to be made by it
hereunder shall not relieve any other Lender of its obligation hereunder, if
any, to make its new US Loan, but no Lender shall be responsible for the failure
of any other Lender to make any new US Loan to be made by such other Lender.

      Section 1.3. Continuations and Conversions of Existing US Loans. US
Borrower may make the following elections with respect to US Loans already
outstanding under this Agreement: to convert US Base Rate Loans to US Dollar
Eurodollar Loans, to convert US Dollar Eurodollar Loans to US Base Rate Loans on
the last day of the Eurodollar Interest Period applicable thereto, to continue
US Dollar Eurodollar Loans beyond the expiration of such Eurodollar Interest
Period by designating a new Eurodollar Interest Period to take effect at the
time of such expiration, and to convert US Swing Loans to US Dollar Eurodollar
Loans simultaneously with the refinancing of such US Swing Loans pursuant to
Section 1.8. In making such elections, US Borrower may combine existing Tranche
A Loans made pursuant to separate Borrowings into one new Borrowing or divide
existing Tranche A Loans made pursuant to one Borrowing into separate new
Borrowings, or combine existing Tranche B Loans made pursuant to separate
Borrowings into one new Borrowing or divide existing Tranche B Loans made
pursuant to one Borrowing into separate new Borrowings, provided that US
Borrower may have no more than ten Borrowings of US Dollar Eurodollar Loans
outstanding at any time. To make any such election, US Borrower must give to US
Agent written notice (or telephonic notice promptly confirmed in writing) of any
such Conversion or Continuation of existing US Loans, with a separate notice
given for each new Borrowing. Each such notice constitutes a
"Continuation/Conversion Notice" hereunder and must:

                                       6
<PAGE>

      (a) to be continued or converted and whether such US Loans are Tranche A
Loans or Tranche B Loans;

      (b) specify the aggregate amount of any Borrowing of US Base Rate Loans
into which such existing US Loans are to be continued or converted and the date
on which such Continuation or Conversion is to occur, or the aggregate amount of
any Borrowing of US Dollar Eurodollar Loans into which such existing US Dollar
Eurodollar Loans are to be continued or converted, the date on which such
Continuation or Conversion is to occur (which shall be the first day of the
Eurodollar Interest Period which is to apply to such US Dollar Eurodollar
Loans), and the length of the applicable Eurodollar Interest Period; and

      (c) be received by US Agent not later than 10:00 a.m., Dallas, Texas time,
on the day on which any such Continuation or Conversion to US Base Rate Loans is
to occur, or the second Business Day preceding the day on which any such
Continuation or Conversion to US Dollar Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by US Borrower as to the matters which
are required to be set out in such written confirmation. Upon receipt of any
such Continuation/Conversion Notice, US Agent shall give each Lender prompt
notice of the terms thereof. Each Continuation/Conversion Notice shall be
irrevocable and binding on US Borrower. During the continuance of any Default,
US Borrower may not make any election to convert existing US Loans made under
this Agreement into US Dollar Eurodollar Loans or continue existing US Loans
made under this Agreement as US Dollar Eurodollar Loans. If (due to the
existence of a Default or for any other reason) US Borrower fails to timely and
properly give any Continuation/Conversion Notice with respect to a Borrowing of
existing US Dollar Eurodollar Loans at least two Business Days prior to the end
of the Eurodollar Interest Period applicable thereto, such US Dollar Eurodollar
Loans shall automatically be converted into US Base Rate Loans at the end of
such Eurodollar Interest Period. No new funds shall be repaid by US Borrower or
advanced by any Lender in connection with any Continuation or Conversion of
existing US Loans pursuant to this section, and no such Continuation or
Conversion shall be deemed to be a new advance of funds for any purpose; such
Continuations and Conversions merely constitute a change in the interest rate
applicable to already outstanding US Loans.

      Section 1.4. Use of Proceeds. US Borrower shall use all US Loans made
under this Agreement to refinance existing indebtedness (including any
commercial paper issued by or for the account of US Borrower), to finance
capital expenditures, to refinance Matured US LC Obligations outstanding under
this Agreement, and to provide working capital for its operations and for other
general business purposes. US Borrower shall use all Letters of Credit issued
under the US Agreement for its general corporate purposes. If any US Loan is
used for a purpose which is governed by Reg U, US Borrower shall comply with Reg
U in all respects. US Borrower represents and warrants that US Borrower is not
engaged principally, or as one of US

                                       7
<PAGE>

Borrower's important activities, in the business of extending credit to others
for the purpose of purchasing or carrying Margin Stock.

may be rejected by US Agent after conferring with, and upon the instruction of,
US Borrower, and US Agent shall notify the bidding Lender of such rejection as
soon as practicable.

                                       10

If any Lender shall elect not to make a Competitive Bid, such Lender shall so
notify US Agent by facsimile not later than 9:00 a.m., Dallas, Texas time, on
the date specified for a Competitive Bid Loan; provided, however, that failure
by any Lender to give such notice shall not cause such Lender to be obligated to
make any Competitive Bid Loan and by such failure such Lender shall be deemed to
have rejected such Competitive Bid. A Competitive Bid submitted by a Lender
shall be irrevocable.

         (c) Promptly, and in no event later than 9:30 a.m., Dallas, Texas time,
on the date specified for a proposed Competitive Bid Loan, US Agent shall notify
US Borrower by facsimile of all the Competitive Bids made, the Competitive Bid
Rate and the principal amount of each Competitive Bid Loan in respect of which a
Competitive Bid was made, and the identity of each Lender that made each
Competitive Bid. US Agent shall send a copy of all Competitive Bids to US
Borrower for its records as soon as practicable after completion of the bidding
process.

         (d) US Borrower may, subject only to the provisions hereof, accept or
reject any Competitive Bid. US Borrower shall notify US Agent by facsimile
pursuant to a Competitive Bid Accept/Reject Letter whether and to what extent US
Borrower has decided to accept or reject any or all of the Competitive Bids, not
later than 10:00 a.m., Dallas, Texas time, on the date specified for a proposed
Competitive Bid Loan; provided, however, that:

            (i) the failure by US Borrower to accept or reject any Competitive
      Bid within the time period specified herein shall be deemed to be a
      rejection of such Competitive Bid,

            (ii) the aggregate amount of the Competitive Bids accepted by US
      Borrower shall not exceed the principal amount specified in the
      Competitive Bid Request,

            (iii) the aggregate amount of all outstanding US Loans and US LC
      Obligations shall never exceed the US Maximum Credit Amount,

            (iv) if US Borrower shall accept a Competitive Bid or Competitive
      Bids made at a particular Competitive Bid Rate, but the amount of such
      Competitive Bid or Competitive Bids shall cause the total amount of
      Competitive Bids to be accepted by US Borrower to exceed the amount
      specified in the Competitive Bid Request, then US Borrower shall accept a
      portion of such Competitive Bid or Competitive Bids in an amount equal to
      the amount specified in the Competitive Bid Request less the amount of all
      other Competitive Bids accepted with respect to such Competitive Bid
      Request, which acceptance, in the case of multiple Competitive Bids at
      such Competitive Bid Rate, shall be made pro rata in accordance with the
      amount of each such Competitive Bid at such Competitive Bid Rate, and

            (v) no Competitive Bid shall be accepted for a Competitive Bid Loan
      unless such Competitive Bid Loan is in a minimum principal amount of US
      $5,000,000 or a higher integral multiple of US $1,000,000; provided,
      however, that if a Competitive Bid Loan must be in an amount less than US
      $5,000,000 because of the provisions of clause (iv) above, such
      Competitive Bid Loan may be for a minimum of US $1,000,000 or any

                                       11
<PAGE>

      higher integral multiple thereof, and in calculating the pro rata
      allocation of acceptances or portions of multiple bids at a particular
      Competitive Bid Rate pursuant to clause (iv), the amounts shall be rounded
      to integral multiples of US $1,000,000 in a manner which shall be in the
      sole and absolute discretion of US Borrower.

      (e) Promptly on each date US Borrower accepts a Competitive Bid, US Agent
shall notify each Lender whether or not its Competitive Bid has been accepted
(and if so, in what amount and at what Competitive Bid Rate) by facsimile
transmission sent by US Agent, and each successful bidder will thereupon become
bound, subject to the other applicable conditions hereof, to make the
Competitive Bid Loan in respect of which its Competitive Bid has been accepted.
After completing the notifications referred to in the immediately preceding
sentence, US Agent shall notify each Lender of the aggregate principal amount of
all Competitive Bids accepted. Each Lender which is to make a Competitive Bid
Loan shall, before 11:00 a.m., Dallas, Texas time, on the borrowing date
specified in the Competitive Bid Request applicable thereto, make available to
US Agent in immediately available funds the amount of each Competitive Bid Loan
to be made by such Lender, and US Agent shall promptly deposit such funds to an
account designated by US Borrower. As soon as practicable thereafter, US Agent
shall notify each Lender of the aggregate amount of Competitive Bid Loans
advanced, the respective Competitive Bid Interest Periods thereof and
Competitive Bid Rate applicable thereto.

      (f) The obligation of US Borrower to repay to each Lender the aggregate
amount of all Competitive Bid Loans made by such Lender, together with interest
accruing in connection therewith, shall be evidenced by promissory notes
(respectively, such Lender's "Competitive Bid Note") made by US Borrower payable
to the order of such Lender in the form of Exhibit L, with appropriate
insertions. The amount of principal owing on any Lender's Competitive Bid Note
at any given time shall be the aggregate amount of all Competitive Bid Loans
theretofore made by such Lender thereunder minus all payments of principal
theretofore received by such Lender thereon. Interest on each Competitive Bid
Note shall accrue and be due and payable as provided herein and therein. US
Borrower shall repay on the final day of the Competitive Bid Interest Period of
each Competitive Bid Loan (such date being that specified by US Borrower for
repayment of such Competitive Bid Loan in the related Competitive Bid Request
and such date being no later than six months after the date of the Competitive
Bid Loan) the then unpaid principal amount of such Competitive Bid Loan. Subject
to Section 1.6 and the payment of amounts described in Section 3.6, US Borrower
shall have the right to prepay any principal amount of any Competitive Bid Loan.

      (g) No Competitive Bid Loan shall be made within five Business Days after
the date of any other Competitive Bid Loan, unless US Borrower and US Agent
shall mutually agree otherwise. If US Agent shall at any time elect to submit a
Competitive Bid in its capacity as a Lender, it shall submit such bid directly
to US Borrower requesting such Competitive Bid one quarter of an hour earlier
than the latest time at which the other Lenders are required to submit their
bids to US Agent.

      Section 1.8. Refinancings of US Swing Loans. US Agent, at any time in its
sole and absolute discretion, may, upon notice given to each Lender by not later
than 11:30 a.m., Dallas, Texas time, on any Business Day, request that each
Tranche A Lender make a Tranche A Loan that is a US Base Rate Loan (or a Tranche
A Loan that is a US Dollar Eurodollar Loan if requested by US Borrower in
accordance with Section 1.2) in an aggregate amount equal to its Tranche A
Percentage Share of the aggregate unpaid principal amount of any outstanding US
Swing Loans for the purpose of refinancing such US Swing Loans (in this section
called a "Refinancing Loan"). In any event, not later than 11:30 a.m., Dallas,
Texas time, on the first day and the fifteenth day of each calendar month (or if
such day is not a Business Day, on the next Business Day), US Agent will notify
each Tranche A Lender of the aggregate amount of US Swing Loans which are then
outstanding and the amount of the Refinancing Loan required to be made by each
Tranche A Lender to refinance such outstanding US Swing Loans (the aggregate
amount of such Refinancing Loan to be made by each Tranche A Lender shall equal
such Tranche A Lender's Tranche A Percentage Share of such outstanding US Swing
Loans). Upon the giving of notices by US Agent described above, each Tranche A
Lender shall promptly remit to US Agent such Refinancing Loan in the manner
described above in Section 1.2, so long as (a) US Agent believed in good faith
that all conditions to making the subject US Swing Loan were satisfied at the
time such US Swing Loan was made, or (b) if the conditions to such US Swing Loan
were not satisfied, the satisfaction of such conditions have been waived in a
writing by Required Tranche A Lenders in accordance with the provisions of this
Agreement (collectively, the "Refinancing Conditions"). The proceeds of the
Refinancing Loans made pursuant to the preceding sentence shall be paid to US
Agent (and not to US Borrower) and applied to the payment of principal of the
outstanding US Swing Loans. If and to the extent any Tranche A Lender shall not
so make its Refinancing Loan, such Tranche A Lender and US Borrower severally
agree to pay to US Agent (for delivery to US Swing Lender) within three days
after demand the amount of such Refinancing Loan together with interest thereon,
for each day from the date such Refinancing Loan was required to be made until
the date such amount is paid to US Agent, with interest at (1) the Federal Funds
Rate, if such Tranche A Lender is making such payment; provided that US Agent
gave notice of the terms of the Borrowing Notice to such Tranche A Lender in
accordance with the terms of this Section 1.2, and (2) the interest rate
applicable at the time to the other Refinancing Loans, if US Borrower is making
such repayment. If neither such Tranche A Lender nor US Borrower pays to US
Agent (for delivery to US Swing Lender) such amount within such three-day
period, US Swing Lender shall in addition to such amount be entitled to recover
from such Tranche A Lender and from US Borrower, on demand, interest thereon at
the Default Rate for US Base Rate Loans, calculated from the date such
Refinancing Loan was required to be made. Each Tranche A Lender's obligation to
make Refinancing Loans pursuant to this Section shall be absolute and
unconditional and shall not be affected by any circumstances, including, without
limitation, (1) any setoff, counterclaim, recoupment, defense or other right
which such Tranche A Lender may have against US Agent, US Borrower or anyone
else for any reason whatsoever; (2) the occurrence or continuance of an Event of
Default or Default; (3) any adverse change in the condition (financial or
otherwise) of US Borrower; (4) any breach of this Agreement by US Borrower, US
Agent or any Tranche A Lender, except with respect to the Refinancing
Conditions; or (5) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing; provided, that in no event shall
a Tranche A Lender be obligated to make a Refinancing Loan pursuant to this

                                       13
<PAGE>

Section if, after giving effect thereto, (i) such Tranche A Lender's Tranche A
Percentage Share of the Tranche A Facility Usage shall exceed such Tranche A
Lender's Percentage Share of the Tranche A Maximum Credit Amount, or (ii) such
Tranche A Lender's Percentage Share of the US Facility Usage shall exceed such
Tranche A Lender's Percentage Share of the US Maximum Credit Amount. If any
Tranche A Lender is prohibited by Law from making a Tranche A Loan to refinance
a US Swing Loan, such Tranche A Lender shall purchase from US Swing Lender a
participation in such US Swing Loan in the amount of such Tranche A Lender's
refinancing obligation hereunder.

      Section 1.9. Re-allocation of Tranche B Maximum Credit Amount and Canadian
Maximum Credit Amount. Borrowers shall have the right (i) to re-allocate up to
US $100,000,000 of the unused Tranche B Maximum Credit Amount to the Canadian
Maximum Credit Amount (a "Tranche B Re-allocation") by reducing the Tranche B
Maximum Credit Amount and increasing the Canadian Maximum Credit Amount by the
same amount and (ii) to re-allocate up to US $100,000,000 of the unused Canadian
Maximum Credit Amount to the Tranche B Maximum Credit Amount (a "Canadian
Re-allocation") by reducing the Canadian Maximum Credit Amount and increasing
the Tranche B Maximum Credit Amount by the same amount; provided that the
Tranche B Maximum Credit Amount shall never be greater than US $625,000,000, the
Canadian Maximum Credit Amount shall never be greater than US $375,000,000; the
aggregate amount of the Tranche B Maximum Credit Amount and the Canadian Maximum
Credit Amount shall never exceed US $800,000,000. A Re-allocation may be made
only on a Business Day which occurs during the Tranche B Revolving Period and
the Canadian Revolving Period, each Re-allocation shall remain in effect for at
least 90 days and thereafter until a subsequent Re-allocation is made in
accordance with the terms set forth in the Loan Documents, and no more than four
Re-allocations may be made during any Fiscal Year.

      (a) To make any Tranche B Re-allocation, US Borrower must give to US Agent
written notice (or telephonic notice promptly confirmed in writing) of such
Tranche B Re-allocation. Each such notice must:

            (i) specify the amount by which the Tranche B Maximum Credit Amount
      will be reduced, which amount must be equal to US $25,000,000 or any
      higher integral multiple of US $1,000,000, and must also be equal to or
      less than the amount by which the Tranche B Maximum Credit Amount then in
      effect exceeds the Tranche B Facility Usage;

            (ii) specify that the Canadian Maximum Credit Amount will be
      increased by the same amount;

            (iii) specify the effective date of such Tranche B Re-allocation
      which must be at least 90 days after the effective date of the immediately
      preceding Re-allocation (whether a Tranche B Re-allocation or a Canadian
      Re-allocation); and

            (iv) be received by US Agent not later than 10:00 a.m., Dallas,
      Texas time, on or before the 10th Business Day preceding the day on which
      such Tranche B Re-allocation is to occur.

                                       14
<PAGE>

      (b) To make any Canadian Re-allocation, Borrowers must give to US Agent
written notice (or telephonic notice promptly confirmed in writing) of such
Canadian Re-allocation. Each such notice must:

            (i) specify the amount by which the Canadian Maximum Credit Amount
      will be reduced, which amount must be equal to US $25,000,000 or any
      higher integral multiple of US $1,000,000, and must also be equal to or
      less than the amount by which the Canadian Maximum Credit Amount then in
      effect exceeds the Canadian Facility Usage;

            (ii) specify that the Tranche B Maximum Credit Amount will be
      increased by the same amount;

            (iii) specify the effective date of such Canadian Re-allocation
      which must be at least 90 days after the effective date of the immediately
      preceding Re-allocation (whether a Tranche B Re-allocation or a Canadian
      Re-allocation); and

            (iv) be received by US Agent not later than 10:00 a.m., Dallas,
      Texas time, on or before the 10th Business Day preceding the day on which
      such Canadian Re-allocation is to occur.

      Each written request or confirmation described in this section constitutes
a "Re-allocation Notice" and must be made in the form and substance of the
"Re-allocation Notice" attached hereto as Exhibit M, duly completed. Each such
telephonic request shall be deemed a representation, warranty, acknowledgment
and agreement by Borrowers as to the matters which are required to be set out in
such written confirmation. Upon receipt of any such Re-allocation Notice, US
Agent shall give Canadian Agent, each Tranche B Lender and each Canadian Lender
prompt notice of the terms thereof. Each Re-allocation Notice shall be
irrevocable and binding on Borrowers.

                         ARTICLE II - Letters of Credit

      Section 2.1. Letters of Credit. Subject to the terms and conditions
hereof, US Borrower may during the Tranche A Commitment Period request US LC
Issuer to issue one or more Letters of Credit, provided that, after taking such
Letter of Credit into account:

      (a the Tranche A Facility Usage does not exceed the Tranche A Maximum
Credit Amount at such time;

      (b the aggregate amount of US LC Obligations arising from Letters of
Credit issued under this Agreement at such time does not exceed the US LC
Sublimit;

      (c the expiration date of such Letter of Credit is prior to the end of the
Tranche A Commitment Period;

                                       15
<PAGE>

      (d such Letter of Credit is to be used for general corporate purposes of
US Borrower or one or more of its Subsidiaries;

      (e such Letter of Credit is not directly or indirectly used to assure
payment of or otherwise support any Indebtedness of any Person other than
Indebtedness of any Restricted Person permitted by this Agreement;

      (f the issuance of such Letter of Credit will be in compliance with all
applicable governmental restrictions, policies, and guidelines and will not
subject US LC Issuer to any cost which is not reimbursable under Article III;

      (g the form and terms of such Letter of Credit are acceptable to US LC
Issuer in its reasonable discretion;

      (h all other conditions in this Agreement to the issuance of such Letter
of Credit have been satisfied.

Subject to the terms and conditions set forth herein, US LC Issuer will, in
reliance upon the agreements of the other Tranche A Lenders set forth in Section
2.3(b), honor any such request if the foregoing conditions (a) through (h) (in
the following Section 2.2 called the "LC Conditions") have been met as of the
date of issuance of such Letter of Credit. US LC Issuer may choose to honor any
such request for any other Letter of Credit but has no obligation to do so and
may refuse to issue any other requested Letter of Credit for any reason which US
LC Issuer in its sole discretion deems relevant. Upon the execution and delivery
of this Agreement by each of the parties hereto, any letters of credit issued
under the Existing Agreement and outstanding as of the date hereof shall be
deemed Letters of Credit issued hereunder as of the date hereof and shall be
subject to the terms and conditions hereof, including without limitation US
Borrower's reimbursement obligations under Section 2.3 and Lenders'
participation obligations under Section 2.3.

      Section 2.2. Requesting Letters of Credit. US Borrower must make written
application for any Letter of Credit at least three Business Days before the
date on which US Borrower desires for US LC Issuer to issue such Letter of
Credit. By making any such written application US Borrower shall be deemed to
have represented and warranted that the LC Conditions described in Section 2.1
will be met as of the date of issuance of such Letter of Credit. Each such
written application for a Letter of Credit must be made in writing in the form
and substance of Exhibit G, the terms and provisions of which are hereby
incorporated herein by reference (or in such other form as may mutually be
agreed upon by US LC Issuer and US Borrower). Two Business Days after the LC
Conditions for a Letter of Credit have been met as described in Section 2.1 (or
if US LC Issuer otherwise desires to issue such Letter of Credit), US LC Issuer
will issue such Letter of Credit at US LC Issuer's office in Dallas, Texas. If
any provisions of any LC Application conflict with any provisions of this
Agreement, the provisions of this Agreement shall govern and control.

                                       16

      Section 2.3. Reimbursement and Participations.

      (a Reimbursement by US Borrower. If the beneficiary of any Letter of
Credit issued hereunder makes a draft or other demand for payment thereunder
then Tranche A Loans that are US Base Rate Loans shall be made by Tranche A
Lenders to US Borrower in the amount of such draft or demand notwithstanding the
fact that one or more conditions precedent to the making of such US Base Rate
Loans may not have been satisfied. Such US Base Rate Loans shall be made
concurrently with US LC Issuer's payment of such draft or demand without any
request therefor by US Borrower and shall be immediately used by US LC Issuer to
repay the amount of the resulting Matured US LC Obligation.

      (b Participation by Lenders. US LC Issuer irrevocably agrees to grant and
hereby grants to each Tranche A Lender, and to induce US LC Issuer to issue
Letters of Credit hereunder, each Tranche A Lender irrevocably agrees to accept
and purchase and hereby accepts and purchases from US LC Issuer, on the terms
and conditions hereinafter stated and for such Tranche A Lender's own account
and risk, an undivided interest equal to such Tranche A Lender's Tranche A
Percentage Share of US LC Issuer's obligations and rights under each Letter of
Credit issued hereunder and the amount of each Matured US LC Obligation paid by
US LC Issuer thereunder. Each Tranche A Lender unconditionally and irrevocably
agrees with US LC Issuer that, if a Matured US LC Obligation is paid under any
Letter of Credit issued hereunder for which US LC Issuer is not reimbursed in
full, whether pursuant to Section 2.3(a) above or otherwise, such Tranche A
Lender shall (in all circumstances and without set-off or counterclaim) pay to
US LC Issuer on demand, in immediately available funds at US LC Issuer's address
for notices hereunder, such Tranche A Lender's Tranche A Percentage Share of
such Matured US LC Obligation (or any portion thereof which has not been
reimbursed by US Borrower). Each Tranche A Lender's obligation to pay US LC
Issuer pursuant to the terms of this subsection is irrevocable and
unconditional. If any amount required to be paid by any Tranche A Lender to US
LC Issuer pursuant to this subsection is paid by such Tranche A Lender to US LC
Issuer within three Business Days after the date such payment is due, US LC
Issuer shall in addition to such amount be entitled to recover from such Tranche
A Lender, on demand, interest thereon calculated from such due date at the
Federal Funds Rate. If any amount required to be paid by any Tranche A Lender to
US LC Issuer pursuant to this subsection is not paid by such Tranche A Lender to
US LC Issuer within three Business Days after the date such payment is due, US
LC Issuer shall in addition to such amount be entitled to recover from such
Tranche A Lender, on demand, interest thereon calculated from such due date at
the Default Rate.

      (c Distributions to Participants. Whenever US LC Issuer has in accordance
with this section received from any Tranche A Lender payment of such Tranche A
Lender's Tranche A Percentage Share of any Matured US LC Obligation, if US LC
Issuer thereafter receives any payment of such Matured US LC Obligation or any
payment of interest thereon (whether directly from US Borrower or by application
of LC Collateral or otherwise, and excluding only interest for any period prior
to US LC Issuer's demand that such Tranche A Lender make such payment of its
Tranche A Percentage Share), US LC Issuer will distribute to such Tranche A
Lender its Tranche A Percentage Share of the amounts so received by US LC
Issuer; provided, however, that if any such payment received by US LC Issuer
must thereafter be

                                       17
<PAGE>

returned by US LC Issuer, such Tranche A Lender shall return to US LC Issuer the
portion thereof which US LC Issuer has previously distributed to it.

      (d Calculations. A written advice setting forth in reasonable detail the
amounts owing under this section, submitted by US LC Issuer to US Borrower or
any Tranche A Lender from time to time, shall be conclusive, absent manifest
error, as to the amounts thereof."

      Section 2.4. Letter of Credit Fees. In consideration of US LC Issuer's
issuance of any Letter of Credit, US Borrower agrees to pay to US LC Issuer for
its own account, a letter of credit fronting fee at a rate equal to 12.5 Basis
Points per annum multiplied by the face amount of such Letter of Credit, payable
on the date of issuance, and (b) to US Agent, for the account of all Tranche A
Lenders in accordance with their respective Tranche A Percentage Shares, a
letter of credit issuance fee calculated by applying the Applicable Margin for
Tranche A Loans to the face amount of all Letters of Credit outstanding on each
day, payable in arrears on the last day of each Fiscal Quarter.

      Section 2.5. No Duty to Inquire.

      (a Drafts and Demands. US LC Issuer is authorized and instructed to accept
and pay drafts and demands for payment under any Letter of Credit without
requiring, and without responsibility for, any determination as to the existence
of any event giving rise to said draft, either at the time of acceptance or
payment or thereafter. US LC Issuer is under no duty to determine the proper
identity of anyone presenting such a draft or making such a demand (whether by
tested telex or otherwise) as the officer, representative or agent of any
beneficiary under any Letter of Credit, and payment by US LC Issuer to any such
beneficiary when requested by any such purported officer, representative or
agent is hereby authorized and approved. US Borrower releases each Lender Party
from, and agrees to hold each Lender Party harmless and indemnified against, any
liability or claim in connection with or arising out of the subject matter of
this section, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR
CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, provided only that no
Lender Party shall be entitled to indemnification for that portion, if any, of
any liability or claim which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment.

      (b Extension of Maturity. If the maturity of any Letter of Credit is
extended by its terms or by Law or governmental action, if any extension of the
maturity or time for presentation of drafts or any other modification of the
terms of any Letter of Credit is made at the request of any Restricted Person,
or if the amount of any Letter of Credit is increased at the request of any
Restricted Person, this Agreement shall be binding upon all Restricted Persons
with respect to such Letter of Credit as so extended, increased or otherwise
modified, with respect to drafts and property covered thereby, and with respect
to any action taken by US LC Issuer, US LC Issuer's correspondents, or any
Lender Party in accordance with such extension, increase or other modification.

                                       18
<PAGE>

      (c Transferees of Letters of Credit. If any Letter of Credit provides that
it is transferable, US LC Issuer shall have no duty to determine the proper
identity of anyone appearing as transferee of such Letter of Credit, nor shall
US LC Issuer be charged with responsibility of any nature or character for the
validity or correctness of any transfer or successive transfers, and payment by
US LC Issuer to any purported transferee or transferees as determined by US LC
Issuer is hereby authorized and approved, and US Borrower releases each Lender
Party from, and agrees to hold each Lender Party harmless and indemnified
against, any liability or claim in connection with or arising out of the
foregoing, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR
CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, provided only that no
Lender Party shall be entitled to indemnification for that portion, if any, of
any liability or claim which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment.

      Section 2.6. LC Collateral.

      (a US LC Obligations in Excess of US Maximum Credit Amount. If, after the
making of all mandatory prepayments required under Section 1.6(b), the US LC
Obligations outstanding under the US Agreement will exceed the Tranche A Maximum
Credit Amount, then in addition to prepayment of the entire principal balance of
the US Loans US Borrower will immediately pay to US LC Issuer an amount equal to
such excess. US LC Issuer will hold such amount as security for the remaining US
LC Obligations outstanding under the US Agreement (all such amounts held as
security for US LC Obligations being herein collectively called "LC Collateral")
and the other US Obligations, and such collateral may be applied from time to
time to any Matured US LC Obligations or other US Obligations which are due and
payable. Neither this subsection nor the following subsection shall, however,
limit or impair any rights which US LC Issuer may have under any other document
or agreement relating to any Letter of Credit, LC Collateral or US LC
Obligation, including any LC Application, or any rights which any Lender Party
may have to otherwise apply any payments by US Borrower and any LC Collateral
under Section 3.1.

      (b Acceleration of US LC Obligations. If the US Obligations or any part
thereof become immediately due and payable pursuant to Section 8.1 then, unless
Tranche A Required Lenders otherwise specifically elect to the contrary (which
election may thereafter be retracted by Tranche A Required Lenders at any time),
all US LC Obligations shall become immediately due and payable without regard to
whether or not actual drawings or payments on the Letters of Credit have
occurred, and US Borrower shall be obligated to pay to US LC Issuer immediately
an amount equal to the aggregate US LC Obligations which are then outstanding.

      (c Investment of LC Collateral. Pending application thereof, all LC
Collateral shall be invested by US LC Issuer in such Investments as US LC Issuer
may choose in its sole discretion. All interest on (and other proceeds of) such
Investments shall be reinvested or applied to Matured US LC Obligations or other
US Obligations which are due and payable. When all US

                                       19
<PAGE>

Obligations have been satisfied in full, including all US LC Obligations, all
Letters of Credit have expired or been terminated, and all of US Borrower's
reimbursement obligations in connection therewith have been satisfied in full,
US LC Issuer shall release any remaining LC Collateral. US Borrower hereby
assigns and grants to US LC Issuer a continuing security interest in all LC
Collateral paid by it to US LC Issuer, all Investments purchased with such LC
Collateral, and all proceeds thereof to secure its Matured US LC Obligations and
the other US Obligations hereunder, each US Note, and the other US Loan
Documents. US Borrower further agrees that US LC Issuer shall have all of the
rights and remedies of a secured party under the Uniform Commercial Code as
adopted in the State of Texas with respect to such security interest and that an
Event of Default under this Agreement shall constitute a default for purposes of
such security interest. When US Borrower is required to provide LC Collateral
for any reason and fails to do so on the day when required, US LC Issuer may
without notice to US Borrower or any other Restricted Person provide such LC
Collateral (whether by transfers from other accounts maintained with US LC
Issuer, or otherwise) using any available funds of US Borrower or any other
Person also liable to make such payments.

                        ARTICLE III - Payments to Lenders

      Section 3.1. General Procedures. US Borrower will make each payment which
it owes under the US Loan Documents to US Agent for the account of the Lender
Party to whom such payment is owed, in lawful money of the United States of
America, without set-off, deduction or counterclaim, and in immediately
available funds. Each such payment must be received by US Agent not later than
11:00 a.m., Dallas, Texas time, on the date such payment becomes due and
payable. Any payment received by US Agent after such time will be deemed to have
been made on the next following Business Day. Should any such payment become due
and payable on a day other than a Business Day, the maturity of such payment
shall be extended to the next succeeding Business Day, and, in the case of a
payment of principal or past due interest, interest shall accrue and be payable
thereon for the period of such extension as provided in the US Loan Document
under which such payment is due. Each payment under a US Loan Document shall be
due and payable at the place provided therein and, if no specific place of
payment is provided, shall be due and payable at the place of payment of US
Agent's US Note. When US Agent collects or receives money on account of the US
Obligations, US Agent shall distribute all money so collected or received by
2:00 p.m. Dallas, Texas time on the Business Day received, if received by 11:00
a.m. Dallas, Texas time, otherwise on the day of deemed receipt, and each Lender
Party shall apply all such money so distributed, as follows:

      (a first, for the payment of all US Obligations which are then due (and if
such money is insufficient to pay all such US Obligations, first to any
reimbursements due US Agent under Section 6.9 or 10.4, then to any reimbursement
due any other Lender Party under Section 10.4, and then to the partial payment
of all other US Obligations then due in proportion to the amounts thereof, or as
Lender Parties shall otherwise agree);

      (b then for the prepayment of amounts owing under the US Loan Documents
(other than principal on the US Notes) if so specified by US Borrower;

                                       20
<PAGE>

      (c then for the prepayment of principal on the US Notes, together with
accrued and unpaid interest on the principal so prepaid; and

      (d last, for the payment or prepayment of any other US Obligations.

All payments applied to principal or interest on any US Note shall be applied
first to any interest then due and payable, then to principal then due and
payable, and last to any prepayment of principal and interest in compliance with
Sections 1.6 and 2.3. All distributions of amounts described in any of
subsections (b), (c) or (d) above shall be made by US Agent pro rata to each
Lender Party then owed US Obligations described in such subsection in proportion
to all amounts owed to all Lender Parties which are described in such
subsection; provided that if any Lender then owes payments to US LC Issuer for
the purchase of a participation under Section 2.3(b) or to US Agent under
Section 9.8, any amounts otherwise distributable under this section to such
Lender shall be deemed to belong to US LC Issuer, or US Agent, respectively, to
the extent of such unpaid payments, and US Agent shall apply such amounts to
make such unpaid payments rather than distribute such amounts to such Lender.

      Section 3.2. Increased Cost and Reduced Return.

      (a If, after the date hereof, the adoption of any applicable Law, rule, or
regulation, or any change in any applicable Law, rule, or regulation, or any
change in the interpretation or administration thereof by any Governmental
Authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender Party (or its Applicable
Lending Office) with any request or directive (whether or not having the force
of Law) of any such Governmental Authority, central bank, or comparable agency:

            (i) shall subject such Lender Party (or its Applicable Lending
      Office) to any tax, duty, or other charge with respect to any US Dollar
      Eurodollar Loans or Competitive Bid Loans, or its obligation to make US
      Dollar Eurodollar Loans, or change the basis of taxation of any amounts
      payable to such Lender Party (or its Applicable Lending Office) under this
      Agreement or its Note in respect of any US Dollar Eurodollar Loans or
      Competitive Bid Loans (other than taxes (including franchise taxes)
      imposed on the overall net income of such Lender Party by the jurisdiction
      in which such Lender Party has its principal office or such Applicable
      Lending Office);

            (ii) shall impose, modify, or deem applicable any reserve, special
      deposit, assessment, or similar requirement (other than the Reserve
      Requirement utilized in the determination of the Adjusted US Dollar
      Eurodollar Rate) relating to any extensions of credit or other assets of,
      or any deposits with or other liabilities or commitments of, such Lender
      Party (or its Applicable Lending Office), including the commitment of such
      Lender Party hereunder; or

                                       21
<PAGE>

            (iii) shall impose on such Lender Party (or its Applicable Lending
      Office) or the London interbank market any other condition affecting this
      Agreement or its US Notes or any of such extensions of credit or
      liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
Party (or its Applicable Lending Office) of making, converting into, continuing,
or maintaining any US Dollar Eurodollar Loans or Competitive Bid Loans or to
reduce any sum received or receivable by such Lender Party (or its Applicable
Lending Office) under this Agreement or its US Notes with respect to any US
Dollar Eurodollar Loans or Competitive Bid Loans, then US Borrower shall pay to
such Lender Party on demand such amount or amounts as will compensate such
Lender Party for such increased cost or reduction. If any Lender Party requests
compensation by US Borrower under this Section 3.2(a), US Borrower may, by
notice to such Lender Party (with a copy to US Agent), suspend the obligation of
such Lender Party to make or continue US Loans of the Type with respect to which
such compensation is requested, or to convert US Loans of any other Type into US
Loans of such Type, until the event or condition giving rise to such request
ceases to be in effect (in which case the provisions of Section 3.5 shall be
applicable); provided that such suspension shall not affect the right of such
Lender Party to receive the compensation so requested.

      (b If, after the date hereof, any Lender Party shall have determined that
the adoption of any applicable Law, rule, or regulation regarding capital
adequacy or any change therein or in the interpretation or administration
thereof by any Governmental Authority, central bank, or comparable agency
charged with the interpretation or administration thereof, or any request or
directive regarding capital adequacy (whether or not having the force of Law) of
any such Governmental Authority, central bank, or comparable agency, has or
would have the effect of reducing the rate of return on the capital of such
Lender Party or any corporation controlling such Lender Party as a consequence
the obligations of such Lender Party hereunder to a level below that which such
Lender Party or such corporation could have achieved but for such adoption,
change, request, or directive (taking into consideration its policies with
respect to capital adequacy), then from time to time upon demand US Borrower
shall pay such Lender Party such additional amount or amounts as will compensate
such Lender Party for such reduction, but only to the extent that such Lender
Party has not been compensated therefor by any increase in the Adjusted US
Dollar Eurodollar Rate; provided that if such Lender Party fails to give notice
to US Borrower of any additional costs within ninety (90) days after it has
actual knowledge thereof, such Lender Party shall not be entitled to
compensation for such additional costs incurred more than ninety (90) days prior
to the date on which notice is given by such Lender Party.

      (c US LC Issuer and each Lender Party shall promptly notify US Borrower
and US Agent of any event of which it has knowledge, occurring after the date
hereof, which will entitle US LC Issuer or such Lender Party to compensation
pursuant to this Section and will designate a different Applicable Lending
Office if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the judgment of such Lender Party, be
otherwise disadvantageous to it. US LC Issuer or any Lender Party claiming
compensation under this Section shall furnish to US Borrower and US Agent a
statement setting forth the additional amount or amounts to be paid to it
hereunder which shall be conclusive in the absence of manifest

                                       22
<PAGE>

error. In determining such amount, US LC Issuer or such Lender Party shall act
in good faith and may use any reasonable averaging and attribution methods.

      Section 3.3. Limitation on Types of US Loans. If on or prior to the first
day of any Eurodollar Interest Period for any US Dollar Eurodollar Loan:

      (a US Agent determines (which determination shall be conclusive) that by
reason of circumstances affecting the relevant market, adequate and reasonable
means do not exist for ascertaining the US Dollar Eurodollar Rate for such
Eurodollar Interest Period; or

      (b US Required Lenders determine (which determination shall be conclusive)
and notify US Agent that the Adjusted US Dollar Eurodollar Rate will not
adequately and fairly reflect the cost to the Lenders of funding US Dollar
Eurodollar Loans or for such Eurodollar Interest Period;

      then US Agent shall give US Borrower prompt notice thereof specifying the
relevant amounts or periods, and so long as such condition remains in effect,
the Lender Parties shall be under no obligation to make additional US Dollar
Eurodollar Loans, continue US Dollar Eurodollar Loans or convert US Base Rate
Loans into US Dollar Eurodollar Loans, and US Borrower shall, on the last day(s)
of the then current Eurodollar Interest Period(s) for the outstanding US Dollar
Eurodollar Loans, either prepay such US Loans or convert such US Loans into US
Base Rate Loans in accordance with the terms of this Agreement.

      Section 3.4. Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender Party or its
Applicable Lending Office to make, maintain, or fund US Dollar Eurodollar Loans
hereunder, then such Lender Party shall promptly notify US Borrower thereof and
such Lender Party's obligation to make or continue US Dollar Eurodollar Loans
and to convert US Base Rate Loans into US Dollar Eurodollar Loans shall be
suspended until such time as such Lender Party may again make, maintain, and
fund US Dollar Eurodollar Loans (in which case the provisions of Section 3.5
shall be applicable).

      Section 3.5. Treatment of Affected US Loans. If the obligation of any
Lender Party to make a particular Type of Loan or to continue, or to convert US
Loans of any other Type into, US Loans of a particular Type shall be suspended
pursuant to Sections 3.2, 3.3 or 3.4 hereof (US Loans of such Type being herein
called "Affected Loans" and such Type being herein called the "Affected Type"),
such Lender Party's Affected Loans shall be automatically converted into US Base
Rate Loans on the last day(s) of the then current Interest Period(s) for
Affected Loans (or, in the case of a Conversion required by Section 3.4 hereof,
on such earlier date as such Lender Party may specify to US Borrower with a copy
to US Agent) and, unless and until such Lender Party gives notice as provided
below that the circumstances specified in Sections 3.2, 3.3 or 3.4 hereof that
gave rise to such Conversion no longer exist:

      (a to the extent that such Lender Party's Affected Loans have been so
converted, all payments and prepayments of principal that would otherwise be
applied to such Lender Party's Affected Loans shall be applied instead to its US
Base Rate Loans; and

                                       23
<PAGE>

      (b all US Loans that would otherwise be made or continued by such Lender
Party as US Loans of the Affected Type shall be made or continued instead as US
Base Rate Loans, and all US Loans of such Lender Party that would otherwise be
converted into US Loans of the Affected Type shall be converted instead into (or
shall remain as) US Base Rate Loans.

If such Lender Party gives notice to US Borrower (with a copy to US Agent) that
the circumstances specified in Section 3.2, 3.3 or 3.4 hereof that gave rise to
the Conversion of such Lender Party's Affected Loans pursuant to this Section no
longer exist (which such Lender Party agrees to do promptly upon such
circumstances ceasing to exist) at a time when US Loans of the Affected Type
made by other Lender Parties are outstanding, such Lender Party's US Base Rate
Loans shall be automatically converted, on the first day(s) of the next
succeeding Interest Period(s) for such outstanding US Loans of the Affected
Type, to the extent necessary so that, after giving effect thereto, all US Loans
held by the Lender Parties holding US Loans of the Affected Type and by such
Lender Party are held pro rata (as to principal amounts, Types, and Interest
Periods) in accordance with their Percentage Shares of the US Maximum Credit
Amount.

      Section 3.6. Compensation. Upon the request of any Lender Party, US
Borrower shall pay to such Lender Party such amount or amounts as shall be
sufficient (in the reasonable opinion of such Lender Party) to compensate it for
any loss, cost, or expense (including loss of anticipated profits) incurred by
it as a result of:

      (a any payment, prepayment, or Conversion of a US Loan (other than a US
Base Rate Loan) for any reason, whether voluntary, mandatory, automatic, by
reason of acceleration, or otherwise, on a date other than the last day of the
Interest Period for such US Loan; or

      (b any failure by US Borrower for any reason (including, without
limitation, the failure of any condition precedent specified in Article IV to be
satisfied) to borrow, convert, continue, or prepay a US Loan (other than a US
Base Rate Loan) on the date for such borrowing, Conversion, Continuation, or
prepayment specified in the relevant notice of borrowing, prepayment,
Continuation, or Conversion under this Agreement.

      Section 3.7. Change of Applicable Lending Office. Each Lender Party agrees
that, upon the occurrence of any event giving rise to the operation of Sections
3.2 through 3.5 with respect to such Lender Party, it will, if requested by US
Borrower, use reasonable efforts (subject to overall policy considerations of
such Lender Party) to designate another Applicable Lending Office, provided that
such designation is made on such terms that such Lender Party and its Applicable
Lending Office suffer no economic, legal or regulatory disadvantage, with the
object of avoiding the consequence of the event giving rise to the operation of
any such section. Nothing in this section shall affect or postpone any of the
obligations of US Borrower or the rights of any Lender Party provided in
Sections 3.2 through 3.5.

      Section 3.8. Replacement of Lenders. If any Lender Party seeks
reimbursement for increased costs under Sections 3.2 through 3.5, or if a US
Borrower is required to increase any such payment under Section 3.9, then within
ninety days thereafter -- provided no Event of

                                       24
<PAGE>

Default then exists -- US Borrower shall have the right (unless such Lender
Party withdraws its request for additional compensation) to replace such Lender
Party by requiring such Lender Party to assign its US Loans, US Notes, US LC
Obligations, Canadian Advances, Canadian Notes, Canadian LC Obligations and its
commitments hereunder and under the Canadian Agreement to an Eligible Assignee
reasonably acceptable to all Borrowers, provided that: (a) all Obligations of
Borrowers owing to such Lender Party being replaced (including such increased
costs, but excluding principal and accrued interest on the US Notes and the
Canadian Notes being assigned) shall be paid in full to such Lender Party
concurrently with such assignment, and (b the replacement Eligible Assignee
shall purchase the foregoing by paying to such Lender Party a price equal to the
principal amount thereof plus accrued and unpaid interest thereon. In connection
with any such assignment US Borrower, US Agent, such Lender Party and the
replacement Eligible Assignee shall otherwise comply with Section 10.5.
Notwithstanding the foregoing rights of US Borrower under this section, however,
US Borrower may not replace any Lender Party which seeks reimbursement for
increased costs under Section 3.2 through 3.5 unless US Borrower is at the same
time replacing all Lender Parties which are then seeking such compensation. In
connection with any such replacement of a Lender Party, US Borrower shall pay
all costs that would have been due to such Lender Party pursuant to Section 3.6
if such Lender Party's US Loans had been prepaid at the time of such
replacement.

      Section 3.9. Taxes. (a) Any and all payments by US Borrower to or for the
account of any Lender Party, US Agent or US LC Issuer hereunder or under any
other US Loan Document shall be made free and clear of and without deduction for
any and all present or future taxes, duties, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding, in
the case of each Lender Party, taxes imposed on its income, and franchise taxes
imposed on it, by the jurisdiction under the Laws of which such Lender Party (or
its Applicable Lending Office) is organized or is a resident for tax purposes or
any political subdivision thereof (all such non-excluded taxes, duties, levies,
imposts, deductions, charges, withholdings, and liabilities being hereinafter in
this section 3.9 referred to as "Taxes"). If US Borrower shall be required by
Law to deduct any Taxes from or in respect of any sum payable under this
Agreement or any other US Loan Document to any Lender Party, (i) the sum payable
shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this section)
such Lender Party receives an amount equal to the sum it would have received had
no such deductions been made, (ii) US Borrower shall make such deductions, and
(iii) US Borrower shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable Law.

      (b In addition, US Borrower agrees to pay any and all present or future
stamp or documentary taxes and any other excise or property taxes or charges or
similar levies which arise from any payment made under this Agreement or any
other US Loan Document or from the execution or delivery of, or otherwise with
respect to, this Agreement or any other US Loan Document (hereinafter in this
Section 3.9 referred to as "Other Taxes").

      (c US Borrower agrees to indemnify each Lender Party, US Agent and US LC
Issuer for the full amount of Taxes and Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this section) paid by such

                                       25
<PAGE>

Lender Party or US Agent (as the case may be) and any liability (including
penalties, interest, and expenses) arising therefrom or with respect thereto.

      (d Each Lender Party organized under the Laws of a jurisdiction outside
the United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Lender Party listed on the signature pages hereof
and on or prior to the date on which it becomes a Lender Party in the case of
each other Lender Party, and from time to time thereafter if requested in
writing by US Borrower or US Agent (but only so long as such Lender Party
remains lawfully able to do so), shall provide US Borrower and US Agent with a
properly executed (i) Internal Revenue Service Form W-8 BEN, or W-8 ECI, as
appropriate, or any successor form prescribed by the Internal Revenue Service,
certifying that such Lender Party is entitled to benefits under an income tax
treaty to which the United States is a party which reduces the rate of
withholding tax on payments of interest or certifying that the income receivable
pursuant to this Agreement is effectively connected with the conduct of a trade
or business in the United States, (ii) Internal Revenue Service Form W-8 or any
successor form prescribed by the Internal Revenue Service certifying to such
Lender Party's foreign status, and (iii) any other form or certificate required
by any taxing authority (including any certificate required by Sections 871(h)
and 881(c) of the Internal Revenue Code), certifying that such Lender Party is
entitled to an exemption from or a reduced rate of tax on payments pursuant to
this Agreement or any of the other US Loan Documents.

         (e For any period with respect to which a Lender Party has failed to
provide US Borrower and US Agent with the appropriate form pursuant to Section
3.9(d) (unless such failure is due to a change in treaty, Law, or regulation
occurring subsequent to the date on which a form originally was required to be
provided), such Lender Party shall not be entitled to receive any additional
amounts or to indemnification under Sections 3.9(a), 3.9(b) or 3.9(c) with
respect to Taxes imposed by the United States; provided, however, that should a
Lender Party, which is otherwise exempt from or subject to a reduced rate of
withholding tax, become subject to Taxes because of its failure to deliver a
form required hereunder, US Borrower shall take such steps as such Lender Party
shall reasonably request to assist such Lender Party to recover such Taxes.
Further, US Borrower shall not be required to indemnify such Lender Party for
any withholding taxes which US Borrower is required to withhold and remit in
respect of any principal, interest or other amount paid or payable by US
Borrower to or for account of any Lender Party hereunder or under any other US
Loan Document.

      (f If US Borrower is required to pay additional amounts to or for the
account of any Lender Party pursuant to this Section, then such Lender Party
will agree to use reasonable efforts to change the jurisdiction of its
Applicable Lending Office so as to eliminate or reduce any such additional
payment which may thereafter accrue if such change, in the judgment of such
Lender Party, is not otherwise disadvantageous to such Lender Party and in the
event Lender Party is reimbursed for an amount paid by US Borrower pursuant to
this Section, it shall promptly return such amount to US Borrower.

      (g Within thirty (30) days after the date of any payment of Taxes, US
Borrower shall furnish to US Agent the original or a certified copy of a receipt
evidencing such payment.

                                       26
<PAGE>

      (h Without prejudice to the survival of any other agreement of US Borrower
hereunder, the agreements and obligations of US Borrower contained in this
section shall survive the termination of the Tranche A Commitment Period and the
Tranche B Revolving Period and the payment in full of the US Notes.

      Section 3.10. Currency Conversion and Currency Indemnity.

      (a Restricted Persons shall make payment relative to any US Obligation in
the currency (the "Agreed Currency") in which the US Obligation was incurred. If
any payment is received on account of any US Obligation in any currency (the
"Other Currency") other than the Agreed Currency (whether voluntarily or
pursuant to an order or judgment or the enforcement thereof or the realization
of any security or the liquidation of such Restricted Person or otherwise
howsoever), such payment shall constitute a discharge of the liability of a
Restricted Person hereunder and under the other US Loan Documents in respect of
such US Obligation only to the extent of the amount of the Agreed Currency which
the relevant Lender Parties are able to purchase with the amount of the Other
Currency received by it on the Business Day next following such receipt in
accordance with its normal procedures and after deducting any premium and costs
of exchange.

      (b If, for the purpose of obtaining or enforcing judgment in any court in
any jurisdiction, it becomes necessary to convert into a particular currency
(the "Judgment Currency") any amount due in the Agreed Currency then the
conversion shall be made on the basis of the rate of exchange prevailing on the
next Business Day following the date such judgment is given and in any event
each Restricted Person shall be obligated to pay the Lender Parties any
deficiency in accordance with Section 3.10(c). For the foregoing purposes "rate
of exchange" means the rate at which the relevant Lender Parties, as applicable,
in accordance with their normal banking procedures are able on the relevant date
to purchase the Agreed Currency with the Judgment Currency after deducting any
premium and costs of exchange.

      (c If (i) any Lender Party receives any payment or payments on account of
the liability of a Restricted Person hereunder pursuant to any judgment or order
in any Other Currency, and (ii) the amount of the Agreed Currency which the
relevant Lender Party is able to purchase on the Business Day next following
such receipt with the proceeds of such payment or payments in accordance with
its normal procedures and after deducting any premiums and costs of exchange is
less than the amount of the Agreed Currency due in respect of such US
Obligations immediately prior to such judgment or order, then US Borrower on
demand shall, and US Borrower hereby agrees to, indemnify and save such Lender
Party harmless from and against any loss, cost or expense arising out of or in
connection with such deficiency. The agreement of indemnity provided for in this
Section 3.10(c) shall constitute an obligation separate and independent from all
other obligations contained in this Agreement, shall give rise to a separate and
independent cause of action, shall apply irrespective of any indulgence granted
by the Lender Parties or any of them 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 hereunder or under any judgment or order.

                  ARTICLE IV - Conditions Precedent to Lending

      Section 4.1. Conditions Precedent to all US Loan and Letters of Credit. No
Lender has any obligation to make any US Loan (including its first), and US LC
Issuer has no obligation to issue any Letter of Credit (including its first),
unless the following conditions precedent have been satisfied:

      (a All representations and warranties made by any Restricted Person in any
US Loan Document shall be true on and as of the date of such US Loan or the date
of issuance of such Letter of Credit (except to the extent that the facts upon
which such representations are based have been changed by the extension of
credit hereunder) as if such representations and warranties had been made as of
the date of such US Loan or the date of issuance of such Letter of Credit.

      (b No Default shall exist at the date of such US Loan or the date of
issuance of such Letter of Credit.

                   ARTICLE V - Representations and Warranties

      To confirm each Lender's understanding concerning Restricted Persons and
Restricted Persons' businesses, properties and obligations and to induce each
Lender to enter into this Agreement and to extend credit hereunder, US Borrower
represents and warrants to each Lender that:

      Section 5.1. No Default. No event has occurred and is continuing which
constitutes a Default.

      Section 5.2. Organization and Good Standing. Each of US Borrower and the
Material Subsidiaries is duly organized, validly existing and in good standing
under the Laws of its jurisdiction of organization, having all powers required
to carry on its business and enter into and carry out the transactions
contemplated hereby. Each of US Borrower and the Material Subsidiaries is duly
qualified, in good standing, and authorized to do business in all other
jurisdictions within the United States wherein the character of the properties
owned or held by it or the nature of the business transacted by it makes such
qualification necessary except where failure to so qualify would not have a
Material Adverse Effect. Each of US Borrower and the Material Subsidiaries has
taken all actions and procedures customarily taken in order to enter, for the
purpose of conducting business or owning property, each jurisdiction outside the
United States wherein the character of the properties owned or held by it or the
nature of the business transacted by it makes such actions and procedures
desirable except where failure to so qualify would not have a Material Adverse
Effect.

      Section 5.3. Authorization. US Borrower and Canadian Borrowers have duly
taken all action necessary to authorize the execution and delivery by it of the
Loan Documents to which it

                                       28
<PAGE>
is a party and to authorize the consummation of the transactions contemplated
thereby and the performance of its obligations thereunder. US Borrower is duly
authorized to borrow funds hereunder.

      Section 5.4. No Conflicts or Consents. The execution and delivery by the
various Restricted Persons of the Loan Documents to which each is a party, the
performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents, do
not and will not (i) conflict with any provision of (A) any Law, (B) the
organizational documents of any Restricted Person, or (C) any agreement,
judgment, license, order or permit applicable to or binding upon any Restricted
Person unless such conflict would not reasonably be expected to have a Material
Adverse Effect, or (ii) result in the acceleration of any Indebtedness owed by
any Restricted Person which would reasonably be expected to have a Material
Adverse Effect, or (iii) result in or require the creation of any Lien upon any
assets or properties of any Restricted Person which would reasonably be expected
to have a Material Adverse Effect, except as expressly contemplated or permitted
in the Loan Documents. Except as expressly contemplated in the Loan Documents no
consent, approval, authorization or order of, and no notice to or filing with,
any Tribunal or third party is required in connection with the execution,
delivery or performance by any Restricted Person of any Loan Document or to
consummate any transactions contemplated by the Loan Documents, unless failure
to obtain such consent would not reasonably be expected to have a Material
Adverse Effect.

      Section 5.5. Enforceable Obligations. This Agreement is, and the other
Loan Documents when duly executed and delivered will be, legal, valid and
binding obligations of each Restricted Person which is a party hereto or
thereto, enforceable in accordance with their terms except as such enforcement
may be limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights.

information delivered herewith or heretofore by any Restricted Person to any
Lender in connection with the negotiation of this Agreement or in connection
with any transaction contemplated hereby contains any untrue statement of a
material fact or omits to state any material fact known to any Restricted Person
(other than industry-wide risks normally associated with the types of businesses
conducted by Restricted Persons) necessary to make the statements contained
herein or therein not misleading as of the date made or deemed made. There is no
fact known to any Restricted Person (other than industry-wide risks normally
associated with the types of businesses conducted by Restricted Persons) that
has not been disclosed to each Lender in writing which would reasonably be
expected to have a Material Adverse Effect.

Statements, in the financial statements delivered to Agent and Lenders pursuant
to Section 6.2, in the Disclosure Schedule or in a Disclosure Report, there are
no actions, suits or legal, equitable, arbitrative or administrative proceedings

Restricted Person before any Tribunal which would reasonably be expected to have
a Material Adverse Effect, and there are no outstanding judgments, injunctions,
writs, rulings or

Plans and Multiemployer Plans are listed in the Disclosure Schedule or in a
Disclosure Report. Except as disclosed in the Initial Financial Statements, in
the Disclosure Schedule or in a Disclosure Report, no Termination Event has
occurred with respect to any ERISA Plan or any Multiemployer Plan and all ERISA
Affiliates are in compliance with ERISA in all material respects. Except as set
forth in the Disclosure Statement or in a Disclosure Report, (i) no "accumulated
funding deficiency" (as defined in Section 412(a) of the Internal Revenue Code)
exists with respect to any ERISA Plan, whether or not waived by the Secretary of
the Treasury or his delegate, (ii) the total amount of withdrawal liability that

$250,000,000, and (iii) the total present value of all unfunded benefit
liabilities within the meaning of Title IV of ERISA of all ERISA Plans (based
upon the actuarial assumptions used to fund each such Plan) did not, as of the
respective annual valuation dates for the most recently ended plan year of each
such Plan, exceed US $250,000,000.

      Section 5.9. Environmental and Other Laws. Except as disclosed in the
Disclosure Schedule: (a) Restricted Persons are conducting their businesses in

Material Adverse Effect; (b) none of the operations or properties of any
Restricted Person is the subject of federal, state or local investigation
evaluating whether any material remedial action is needed to respond to a
release of any Hazardous Materials into the environment or to the improper
storage or disposal (including storage or disposal at offsite locations) of any
Hazardous Materials, unless such remedial action would not reasonably be
expected to have a Material Adverse Effect; and (c) no Restricted Person (and to
the best knowledge of US Borrower, no other Person) has filed any notice under
any Law indicating that any Restricted Person is responsible for the improper
release into the environment, or the improper storage or disposal, of any
material amount of any Hazardous Materials or that any Hazardous Materials have
been improperly released, or are improperly stored or disposed of, upon any
property of any Restricted Person, unless such failure to so comply would not
reasonably be expected to have a Material Adverse Effect.

      Section 5.10. US Borrower's Subsidiaries. US Borrower does not presently
have any Material Subsidiary except those listed in the Disclosure Schedule or
in a Disclosure Report (it being understood that inclusion of a Subsidiary on
the Disclosure Schedule does not mean that such Subsidiary is a Material
Subsidiary). US Borrower owns, directly or indirectly, the equity interest in
each of its Material Subsidiaries which is indicated in the Disclosure Schedule
or in a Disclosure Report.

      Section 5.11. Title to Properties; Licenses. Each Restricted Person has
good and defensible title to all of its material properties and assets, free and
clear of all Liens other than Permitted Liens and of all impediments to the use
of such properties and assets in such Restricted

                                       30
<PAGE>

Person's business except to the extent failure to have such title would not have
a Material Adverse Effect. Each Restricted Person possesses all licenses,
permits, franchises, patents, copyrights, trademarks and trade names, and other
intellectual property (or otherwise possesses the right to use such intellectual
property) which are necessary to carry out its business as presently conducted
and as presently proposed to be conducted hereafter except to the extent failure
to possess such licenses, permits, franchises, and intellectual property would
not have a Material Adverse Effect, and no Restricted Person is in violation in
any material respect of the terms under which it possesses such intellectual
property or the right to use such intellectual property except to the extent any
such violation would not have a Material Adverse Effect.

      Section 5.12. Government Regulation. Neither US Borrower nor any other
Restricted Person owing Obligations is subject to regulation under the Public
Utility Holding Company Act of 1935, the Federal Power Act, the Investment
Company Act of 1940 (as any of the preceding acts have been amended) or any
other Law which regulates the incurring by such Person of Indebtedness,
including Laws relating to common contract carriers or the sale of electricity,
gas, steam, water or other public utility services.

      Section 5.13. Solvency. Upon giving effect to the issuance of the US
Notes, the execution of the US Loan Documents by US Borrower and the
consummation of the transactions contemplated hereby, US Borrower will be
solvent (as such term is used in applicable bankruptcy, liquidation,
receivership, insolvency or similar Laws).

Restricted Person's property, including its books of account, other books and

contract or other instrument to which any of them is a party or by which any of
them or any of their properties is bound, if such default would have a Material
Adverse Effect,

      (d) the occurrence of any Termination Event which could reasonably be

amounts it is required to pay under any US Loan Document, US Agent may pay the

any failure by US Agent to so notify US Borrower shall not limit or otherwise
impair US Agent's ability to make any such payment. US Borrower shall
immediately reimburse US Agent for any such payments and each amount paid by US
Agent shall constitute an US Obligation owed hereunder which is due and payable
on the date such amount is paid by US Agent.

      Section 6.10. Interest. US Borrower hereby promises to each Lender Party
to pay interest at the Default Rate applicable to Base Rate Loans on all US
Obligations (including US Obligations to pay fees or to reimburse or indemnify

potential liability or claim in excess of US $250,000,000.

      Section 6.13. Bank Accounts; Offset. US Borrower hereby agrees that each
US Lender shall have the right to offset (which shall be in addition to all
other interests, liens, and rights of any Lender at common Law, under the Loan

without notice to US Borrower), any and all items hereinabove referred to. To
the extent that US Borrower has accounts designated as royalty or joint interest
owner accounts, the foregoing right of offset shall not extend to funds in such
accounts which belong to, or otherwise arise from payments to US Borrower for
the account of, third party royalty or joint interest owners.

agreement, condition or provision of any US Loan Document, and such failure
remains unremedied for a period of thirty (30) days after notice of such failure
is given by US Agent to US Borrower;

      (d) Any representation or warranty previously, presently or hereafter made
in writing by or on behalf of any Restricted Person in connection with any US
Loan Document shall prove to have been false or incorrect in any material
respect on any date on or as of which made provided that if such falsity or lack
of correctness is capable of being remedied or cured within a 30-day period, US
Borrower shall (subject to the other provisions of this Section 8.1) have a
period of 30 days after written notice thereof has been given to US Borrower by
US Agent within which to remedy or cure such lack of correctness; or this
Agreement, any US Note, or the Guaranty executed by US Guarantor is asserted to
be or at any time ceases to be valid, binding and enforceable in any material
respect as warranted in Section 5.5 for any reason other than its release or
subordination by US Agent;

      (e) Any Restricted Person fails to duly pay any Indebtedness in excess of
US $150,000,000 constituting principal or interest owed by it with respect to
borrowed money or money otherwise owed under any note, bond, or similar
instrument, or (ii) breaches or defaults in the performance of any agreement or
instrument by which any such Indebtedness is issued, evidenced, governed, or
secured, other than a breach or default described in clause (i) above, and any
such failure, breach or default results in the acceleration of such
Indebtedness; provided that notwithstanding any provision of this subsection (e)
to the contrary, to the extent that the terms of any such agreement or
instrument governing the sale, pledge or disposal of Margin Stock or

                                       39
<PAGE>

utilization of the proceeds of such Indebtedness in connection therewith would
result in such acceleration and in a Default or an Event of Default under this
Agreement, and would cause this Agreement or any US Loan to be subject to the
margin requirements or any other restriction under Reg U, then such acceleration
shall not constitute a Default or Event of Default under this subsection (e);

      (f) Either of the following occurs: (i) a Termination Event occurs and the
total amount of withdrawal liability that would be incurred by all ERISA
Affiliates upon their complete withdrawal from all Multiemployer Plans would
reasonably be expected to exceed US $250,000,000, or (ii) a Termination Event
occurs and the total present value of all unfunded benefit liabilities within
the meaning of Title IV of ERISA of all ERISA Plans (based upon the actuarial
assumptions used to fund each such Plan) would reasonably be expected to exceed
US $250,000,000;

      (g) Any Change of Control occurs;

      (h) US Borrower, US Guarantor or any other Restricted Person having assets
with a book value of at least US $250,000,000:

            (i) suffers the entry against it of a judgment, decree or order for
      relief by a Tribunal of competent jurisdiction in an involuntary
      proceeding commenced under any applicable bankruptcy, insolvency or other
      similar Law of any jurisdiction now or hereafter in effect, including the
      federal Bankruptcy Code, as from time to time amended, or has any such
      proceeding commenced against it which remains undismissed for a period of
      thirty days; or

            (ii) commences a voluntary case under any applicable bankruptcy,
      insolvency or similar Law now or hereafter in effect, including the

      any such Law; or makes a general assignment for the benefit of creditors;
      or fails generally to pay (or admits in writing its inability to pay) its
      debts as such debts become due; or takes corporate or other action to
      authorize any of the foregoing; or

            (iii) suffers the appointment of or taking possession by a receiver,
      liquidator, assignee, custodian, trustee, sequestrator or similar official
      of all or a substantial part of its property in a proceeding brought
      against or initiated by it, and such appointment or taking possession is
      neither made ineffective nor discharged within thirty days after the
      making thereof, or such appointment or taking possession is at any time
      consented to, requested by, or acquiesced to by it; or

            (iv) suffers the entry against it of a final judgment for the
      payment of money in an amount that exceeds (x) the valid and collectible
      insurance in respect thereof or (y) the amount of an indemnity with
      respect thereto reasonably acceptable to the US Required Lenders by US
      $250,000,000 or more, unless the same is discharged within thirty days

                                       40
<PAGE>

      after the date of entry thereof or an appeal or appropriate proceeding for
      review thereof is taken within such period and a stay of execution pending
      such appeal is obtained; or

            (v) suffers a writ or warrant of attachment or similar process to be
      issued by any Tribunal against all or any part of its property having a
      book value of at least US $250,000,000, and such writ or warrant of
      attachment or any similar process is not stayed or released within thirty
      days after the entry or levy thereof or after any stay is vacated or set
      aside; and

      (i) Any "Event of Default" occurs under the Canadian Agreement.

Upon the occurrence of an Event of Default described in subsection (h)(i),
(h)(ii) or (h)(iii) of this section with respect to US Borrower, all of the US
Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by US Borrower and each Restricted Person who at any
time ratifies or approves this Agreement. Upon any such acceleration, any
obligation of any Lender to make any further US Loans, any obligation of US LC
Issuer to issue Letters of Credit hereunder, and any obligation of US Swing
Lender to make any further US Swing Loans shall be permanently terminated.
During the continuance of any other Event of Default, US Agent at any time and
from time to time may (and upon written instructions from US Required Lenders,
US Agent shall), without notice to US Borrower or any other Restricted Person,
do either or both of the following: (1) terminate any obligation of Lenders to
make US Loans hereunder, any obligation of US LC Issuer to issue Letters of
Credit hereunder, and any obligation of US Swing Lender to make US Swing Loans
hereunder, and (2) declare any or all of the US Obligations immediately due and
payable, and all such US Obligations shall thereupon be immediately due and
payable, without demand, presentment, notice of demand or of dishonor and
nonpayment, protest, notice of protest, notice of intention to accelerate,
declaration or notice of acceleration, or any other notice or declaration of any
kind, all of which are hereby expressly waived by US Borrower and each
Restricted Person who at any time ratifies or approves this Agreement.

      Section 8.2. Remedies. If any Event of Default shall occur and be
continuing, each Lender Party may protect and enforce its rights under the US
Loan Documents by any appropriate proceedings, including proceedings for
specific performance of any covenant or agreement contained in any Loan
Document, and each Lender Party may enforce the payment of any US Obligations
due it or enforce any other legal or equitable right which it may have. All
rights, remedies and powers conferred upon Lender Parties under the US Loan
Documents shall be deemed cumulative and not exclusive of any other rights,
remedies or powers available under the US Loan Documents or at Law or in equity.

                              ARTICLE IX - US Agent

      Section 9.1. Appointment, Powers, and Immunities.

                                       41
<PAGE>

      (a) Each Lender hereby irrevocably appoints and authorizes US Agent to act
as its agent under this Agreement and the other US Loan Documents with such
powers and discretion as are specifically delegated to US Agent by the terms of
this Agreement and the other US Loan Documents, together with such other powers
as are reasonably incidental thereto. The Agent-Related Persons: (i) shall not
have any duties or responsibilities except those expressly set forth in this
Agreement and shall not be trustees or fiduciaries for any Lender; (ii) shall
not be responsible to the Lenders for any recital, statement, representation, or
warranty (whether written or oral) made in or in connection with any Loan
Document or any certificate or other document referred to or provided for in, or
received by any of them under, any Loan Document, or for the value, validity,
effectiveness, genuineness, enforceability, or sufficiency of any Loan Document,
or any other document referred to or provided for therein or for any failure by
any Restricted Person or any other Person to perform any of its obligations
thereunder; (iii) shall not be responsible for or have any duty to ascertain,
inquire into, or verify the performance or observance of any covenants or
agreements by any Restricted Person or the satisfaction of any condition or to
inspect the property (including the books and records) of any Restricted Person
or any of its Subsidiaries or Affiliates or for the failure of any Restricted
Person or Lender Party to perform its obligations under any Loan Document; (iv)
shall not be required to initiate or conduct any litigation or collection
proceedings under any Loan Document; and (v) shall not be responsible for any
action taken or omitted to be taken by it under or in connection with any Loan
Document, except for its own gross negligence or willful misconduct; provided,
however, that no action taken in accordance with the directions of the number of
Lenders herein specified with respect to a particular action shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section.
US Agent may employ agents and attorneys-in-fact and shall not be responsible
for the negligence or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. Without limiting the generality of the
foregoing sentence, the use of the term "agent" herein and in the other Loan
Documents with reference to US Agent is not intended to connote any fiduciary or
other implied (or express) obligations arising under agency doctrine of any
applicable Law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

      (b) US LC Issuer shall act on behalf of the Lenders with respect to any
Letters of Credit issued by it and the documents associated therewith until such
time (and except for so long) as the US Agent may agree at the request of the
Required Lenders to act for US LC Issuer with respect thereto; provided,
however, that US LC Issuer shall have all of the benefits and immunities (i)
provided to the US Agent in this Article IX with respect to any acts taken or
omissions suffered by US LC Issuer in connection with Letters of Credit issued
by it or proposed to be issued by it and the application and agreements for
letters of credit pertaining to the Letters of Credit as fully as if the term
"US Agent" as used in this Article IX included US LC Issuer with respect to such
acts or omissions, and (ii) as additionally provided herein with respect to US
LC Issuer.

      Section 9.2. Reliance by US Agent. US Agent shall be entitled to rely upon
any certification, notice, instrument, writing, or other communication
(including, without limitation,

                                       42
<PAGE>

any thereof by telephone or telecopy) believed by it to be genuine and correct
and to have been signed, sent or made by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel (including counsel for
any Restricted Person), independent accountants, and other experts selected by
US Agent. US Agent may deem and treat the payee of any Note as the holder
thereof for all purposes hereof unless and until US Agent receives and accepts
an Assignment and Assumption executed in accordance with Section 10.6 hereof. US
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement or any other Loan Document in accordance with a
request or consent of the Tranche A Required Lenders, Tranche B Required
Lenders, US Required Lenders, US Majority Lenders or all Lenders, if required
hereunder, and such request and any action taken or failure to act pursuant
thereto shall be binding upon all Lenders and participants. Where this Agreement
expressly permits or prohibits an action unless the Tranche A Required Lenders,
Tranche B Required Lenders, US Required Lenders, US Majority Lenders or all
Lenders otherwise determine, the US Agent shall, and in all other instances, the
US Agent may, but shall not be required to, initiate any solicitation for the
consent or a vote of the Lenders.

      (b) For purposes of determining compliance with the conditions specified
in Section 4.1, each Lender that has signed this Agreement shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document
or other matter either sent by US Agent to such Lender for consent, approval,
acceptance or satisfaction, or required thereunder to be consented to or
approved by or acceptable or satisfactory to a Lender; provided, however, that
US Agent shall not be required to take any action that exposes US Agent to
personal liability or that is contrary to any Loan Document or applicable Law or
unless it shall first be indemnified to its satisfaction by the Lenders against
any and all liability and expense which may be incurred by it by reason of
taking any such action.

      Section 9.3. Defaults. US Agent shall not be deemed to have knowledge or
notice of the occurrence of a Default or Event of Default unless US Agent has
received written notice from a Lender or US Borrower specifying such Default or
Event of Default and stating that such notice is a "Notice of Default". In the
event that US Agent receives such a notice of the occurrence of a Default or
Event of Default, US Agent shall give prompt notice thereof to the Lenders. US
Agent shall (subject to Section 9.1 hereof) take such action with respect to
such Default or Event of Default as shall reasonably be directed by the US
Required Lenders. Notwithstanding the foregoing, unless and until US Agent shall
have received such directions, US Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interest of the Lenders.

      Section 9.4. Rights as Lender. With respect to its Percentage Share of the
US Maximum Credit Amount and the US Loans made by it, US Agent (and any
successor acting as US Agent) in its capacity as a Lender hereunder shall have
the same rights and powers hereunder as any other Lender and may exercise the
same as though it were not acting as US Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include US Agent in its
individual capacity. US Agent (and any successor acting as US Agent) and its
Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make Investments in, provide services to, and
generally engage in any kind of lending, trust, or other

                                       43
<PAGE>

business with any Restricted Person or any of its Subsidiaries or Affiliates as
if it were not acting as US Agent, and US Agent (and any successor acting as US
Agent) and its Affiliates may accept fees and other consideration from any
Restricted Person or any of its Subsidiaries or Affiliates for services in
connection with this Agreement or otherwise without having to account for the
same to the Lenders.

      Section 9.5. Indemnification. The Lenders agree to indemnify each
Agent-Related Person (to the extent not reimbursed under Section 10.4 hereof,
but without limiting the obligations of US Borrower under such section) ratably
in accordance with their respective Percentage Shares, for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including attorneys' fees), or disbursements of any kind and
nature whatsoever that may be imposed on, incurred by or asserted against US
Agent (including by any Lender) in any way relating to or arising out of any
Loan Document or the transactions contemplated thereby or any action taken or
omitted by US Agent under any Loan Document (INCLUDING ANY OF THE FOREGOING
ARISING FROM THE NEGLIGENCE OF US AGENT); provided that no Lender shall be
liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Person to be indemnified, and provided
further that no action taken in accordance with the directions of the number of
Lenders herein specified with respect to a particular action shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section.
Without limitation of the foregoing, each Lender agrees to reimburse US Agent
promptly upon demand for its ratable share of any costs or expenses payable by
US Borrower under Section 10.4, to the extent that US Agent is not promptly
reimbursed for such costs and expenses by US Borrower. The agreements contained
in this section shall survive payment in full of the US Loans and all other
amounts payable under this Agreement.

      Section 9.6. Non-Reliance on US Agent and Other Lenders. Each Lender
agrees that it has, independently and without reliance on US Agent or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of US Borrower and its Subsidiaries
and decision to enter into this Agreement and that it will, independently and
without reliance upon US 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 analysis and decisions in taking or not taking action under the US Loan
Documents. Except for notices, reports, and other documents and information
expressly required to be furnished to the Lenders by US Agent hereunder, US
Agent shall not have any duty or responsibility to provide any Lender with any
credit or other information concerning the affairs, financial condition, or
business of any Restricted Person or any of its Subsidiaries or Affiliates that
may come into the possession of US Agent or any of its Affiliates.

      Section 9.7. Administrative Agent in its Individual Capacity. Bank of
America and its Affiliates may make loans to, issue letters of credit for the
account of, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other
business with each of the Restricted Persons and their respective Affiliates as
though Bank of

                                       44
<PAGE>

America were not the US Agent or the US LC Issuer hereunder and without notice
to or consent of Lenders. Lenders acknowledge that, pursuant to such activities,
Bank of America or its Affiliates may receive information regarding any
Restricted Person or its Affiliates (including information that may be subject
to confidentiality obligations in favor of such Restricted Person or such
Affiliate) and acknowledge that the US Agent shall be under no obligation to
provide such information to them. With respect to its US Loans, Bank of America
shall have the same rights and powers under this Agreement as any other Lender
and may exercise such rights and powers as though it were not the US Agent or
the US LC Issuer, and the terms "Lender" and "Lenders" include Bank of America
in its individual capacity.

      Section 9.8. Sharing of Set-Offs and Other Payments. Each Lender Party
agrees that if it shall, whether through the exercise of rights under US Loan
Documents or rights of banker's lien, set off, or counterclaim against US
Borrower or otherwise, obtain payment of a portion of the aggregate Obligations
owed to it which, taking into account all distributions made by US Agent under
Section 3.1, causes such Lender Party to have received more than it would have
received had such payment been received by US Agent and distributed pursuant to
Section 3.1, then (a) it shall be deemed to have simultaneously purchased and
shall be obligated to purchase interests in the Obligations as necessary to
cause all Lender Parties to share all payments as provided for in Section 3.1,
and (b) such other adjustments shall be made from time to time as shall be
equitable to ensure that US Agent and all Lender Parties share all payments of
Obligations as provided in Section 3.1; provided, however, that nothing herein
contained shall in any way affect the right of any Lender Party to obtain
payment (whether by exercise of rights of banker's lien, set-off or counterclaim
or otherwise) of indebtedness other than the Obligations. US Borrower expressly
consents to the foregoing arrangements and agrees that any holder of any such
interest, may to the fullest extent permitted by Law exercise any and all rights
of banker's lien, set-off, or counterclaim as fully as if such holder were a
holder of the Obligations in the amount of such interest. If all or any part of
any funds transferred pursuant to this section is thereafter recovered from the
seller under this section which received the same, the purchase provided for in
this section shall be deemed to have been rescinded to the extent of such
recovery, together with interest, if any, if interest is required pursuant to
the order of a Tribunal order to be paid on account of the possession of such
funds prior to such recovery.

      Section 9.9. Investments. Whenever US Agent in good faith determines that
it is uncertain about how to distribute to Lender Parties any funds which it has
received, or whenever US Agent in good faith determines that there is any
dispute among Lender Parties about how such funds should be distributed, US
Agent may choose to defer distribution of the funds which are the subject of
such uncertainty or dispute. If US Agent in good faith believes that the
uncertainty or dispute will not be promptly resolved, or if US Agent is
otherwise required to invest funds pending distribution to Lender Parties, US
Agent shall invest such funds pending distribution; all interest on any such
Investment shall be distributed upon the distribution of such Investment and in
the same proportion and to the same Persons as such Investment. All moneys
received by US Agent for distribution to Lender Parties (other than to the
Person who is US Agent in its separate capacity as a Lender Party) shall be held
by US Agent pending such distribution solely as US Agent for such Lender
Parties, and US Agent shall have no equitable title to any portion thereof.

      Section 9.10. Benefit of Article IX. The provisions of this Article (other
than the following Section 9.11) are intended solely for the benefit of Lender
Parties, and no Restricted

                                       45
<PAGE>

Person shall be entitled to rely on any such provision or assert any such
provision in a claim or defense against any Lender. Lender Parties may waive or
amend such provisions as they desire without any notice to or consent of US
Borrower or any Restricted Person.

      Section 9.11. Resignation. US Agent may resign at any time by giving
written notice thereof to Lenders and US Borrower. Each such notice shall set
forth the date of such resignation. Upon any such resignation, US Required
Lenders shall have the right to appoint a successor US Agent and if no Default
or Event of Default has occurred and is continuing, US Required Lenders shall
obtain the consent of US Borrower. A successor must be appointed for any
retiring US Agent, and such US Agent's resignation shall become effective when
such successor accepts such appointment. If, within thirty days after the date
of the retiring US Agent's resignation, no successor US Agent has been appointed
and has accepted such appointment, then the retiring US Agent may appoint a
successor US Agent, which shall be a commercial bank organized or licensed to
conduct a banking or trust business under the Laws of the United States of
America or of any state thereof and if no Default or Event of Default has
occurred and is continuing, retiring US Agent shall obtain the consent of US
Borrower. Upon the acceptance of any appointment as US Agent hereunder by a
successor US Agent, the retiring US Agent shall be discharged from its duties
and obligations under this Agreement and the other US Loan Documents. After any
retiring US Agent's resignation hereunder the provisions of this Article IX
shall continue to inure to its benefit as to any actions taken or omitted to be
taken by it while it was US Agent under the US Loan Documents.

      Section 9.12. Lenders to Remain Pro Rata. It is the intent of all parties
hereto that the pro rata share of each Lender in the Tranche B Loans and in the
Canadian Obligations and the related rights and obligations of such Lender under
the Loan Documents shall be substantially the same at all times during the term
of this Agreement. Accordingly, the initial Tranche B Percentage Share of each
Tranche B Lender in the Tranche B Maximum Credit Amount will be the same as the
initial Percentage Share of such Lender in the Canadian Maximum Credit Amount.
All subsequent assignments and adjustments of the interests of the Tranche B
Lenders in the Tranche B Facility and the Canadian Obligations will be made so
as to maintain such a pro rata arrangement; provided that for the purposes of
determining these pro rata shares, any Percentage Share held by any Lender's
Affiliates shall be included in determining the interests of such Lender.

      Section 9.13. Other Agents. None of the Lenders identified on the facing
page or signature pages of this Agreement as a "syndication agent" or "joint
lead arranger" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of the Lenders so
identified shall have or be deemed to have any fiduciary relationship with any
Lender. Each Lender acknowledges that it has not relied, and will not rely, on
any of the Lenders so identified in deciding to enter into this Agreement or in
taking or not taking action hereunder.

                            ARTICLE X - Miscellaneous

      Section 10.1. Waivers and Amendments; Acknowledgments.

                                       46
<PAGE>

      (a) Waivers and Amendments. No failure or delay (whether by course of
conduct or otherwise) by any Lender Party in exercising any right, power or
remedy which such Lender Party may have under any of the US Loan Documents shall
operate as a waiver thereof or of any other right, power or remedy, nor shall
any single or partial exercise by any Lender Party of any such right, power or
remedy preclude any other or further exercise thereof or of any other right,
power or remedy. No waiver of any provision of any US Loan Document and no
consent to any departure therefrom shall ever be effective unless it is in
writing and signed as provided below in this section, and then such waiver or
consent shall be effective only in the specific instances and for the purposes
for which given and to the extent specified in such writing. No notice to or
demand on any Restricted Person shall in any case of itself entitle any
Restricted Person to any other or further notice or demand in similar or other
circumstances. This Agreement and the other US Loan Documents set forth the
entire understanding between the parties hereto with respect to the transactions
contemplated herein and therein and supersede all prior discussions and
understandings with respect to the subject matter hereof and thereof, and no
waiver, consent, release, modification or amendment of or supplement to this
Agreement or the other US Loan Documents shall be valid or effective against any
party hereto unless the same is in writing and signed by (i) if such party is US
Borrower, by US Borrower, (ii) if such party is US Agent or US LC Issuer, by
such party, (iii) in any provisions requiring the consent of Tranche A Required
Lenders, if such party is a Tranche A Lender, by such Tranche A Lender or by US
Agent on behalf of Tranche A Lenders with the written consent of Tranche A
Required Lenders, (iv) in any provisions requiring the consent of Tranche B
Required Lenders, if such party is a Tranche B Lender, by such Tranche B Lender
or by US Agent on behalf of Tranche B Lenders with the written consent of
Tranche B Required Lenders and (v) if such party is a Lender, by such Lender or
by US Agent on behalf of Lenders with the written consent of US Required Lenders
(which consent has already been given as to the termination of the US Loan
Documents as provided in Section 10.10). Notwithstanding the foregoing or
anything to the contrary herein, US Agent shall not, without the prior consent
of US Majority Lenders and Canadian Majority Lenders, execute and deliver on
behalf of such Lender any waiver or amendment which would increase the US
Maximum Credit Amount hereunder, except in connection with the Re-allocations
described in Section 1.9. Notwithstanding the foregoing or anything to the
contrary herein, US Agent shall not, without the prior consent of each
individual US Lender, execute and deliver on behalf of such Lender any waiver or
amendment which would: (1) waive any of the conditions specified in Article IV,
(2) increase the maximum amount which such Lender is committed hereunder to
lend, (3) reduce any fees payable to such Lender hereunder, or the principal of,
or interest on, such Lender's Note, (4) postpone any date fixed for any payment
of any such fees, principal or interest, (5) change the aggregate amount of
Percentage Shares which is required for US Agent, Lenders or any of them to take
any particular action under the US Loan Documents, (6) release US Borrower or US
Guarantor (to the extent not otherwise released pursuant to the terms of the US
Guaranty) from its obligation to pay such Lender's Loan (it being understood and
agreed that neither any assignment by Devon Financing ULC contemplated by
Section 13 of the Devon Financing ULC Guaranty executed and delivered to US
Agent nor the termination of any Guaranty in accordance with the terms thereof
shall constitute a release of US Borrower or the US Guarantor within the meaning
of this Section 10.1(a) or shall require the consent of any Lender), or (7)
amend this Section 10.1(a), except in connection with the Re-allocations
described

                                       47
<PAGE>

in Section 1.9. Notwithstanding the foregoing or anything to the contrary
herein, US Agent shall not, (a) without the prior consent of each individual
Tranche A Lender, execute and deliver on behalf of such Tranche A Lender any
waiver or amendment which would amend the definition herein of "Tranche A
Required Lenders" and (b) without the prior consent of each individual Tranche B
Lender, execute and deliver on behalf of such Tranche B Lender any waiver or
amendment which would amend the definition herein of "Tranche B Required
Lenders."

      (b) Acknowledgments and Admissions. US Borrower hereby represents,
warrants, acknowledges and admits that (i) it has been advised by counsel in the
negotiation, execution and delivery of the US Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement and
the other US Loan Documents to which it is a party, without reliance on any
representation, warranty, covenant or undertaking by US Agent or any Lender,
whether written, oral or implicit, other than as expressly set out in this
Agreement or in another Loan Document delivered on or after the date hereof,
(iii) there are no representations, warranties, covenants, undertakings or
agreements by any Lender as to the US Loan Documents except as expressly set out
in this Agreement or in another Loan Document delivered on or after the date
hereof, (iv) no Lender has any fiduciary obligation toward US Borrower with
respect to any Loan Document or the transactions contemplated thereby, (v) the
relationship pursuant to the US Loan Documents between US Borrower and the other
Restricted Persons, on one hand, and each Lender, on the other hand, is and
shall be solely that of debtor and creditor, respectively, (vi) no partnership
or joint venture exists with respect to the US Loan Documents between any
Restricted Person and any Lender, (vii) US Agent is not US Borrower's US Agent,
but US Agent for Lenders, (viii) without limiting any of the foregoing, US
Borrower is not relying upon any representation or covenant by any Lender, or
any representative thereof, and no such representation or covenant has been
made, that any Lender will, at the time of an Event of Default or Default, or at
any other time, waive, negotiate, discuss, or take or refrain from taking any
action permitted under the US Loan Documents with respect to any such Event of
Default or Default or any other provision of the US Loan Documents, and (ix) all
Lender Parties have relied upon the truthfulness of the acknowledgments in this
section in deciding to execute and deliver this Agreement and to become
obligated hereunder.

      (c) Joint Acknowledgment. THIS WRITTEN AGREEMENT AND THE OTHER US LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

      THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

      Section 10.2. Survival of Agreements; Cumulative Nature. All of Restricted
Persons' various representations, warranties, covenants and agreements in the US
Loan Documents shall survive the execution and delivery of this Agreement and
the other US Loan Documents and the performance hereof and thereof, including
the making or granting of the US Loans and the

                                       48
<PAGE>

delivery of the US Notes and the other US Loan Documents, and shall further
survive until all of the US Obligations are paid in full to each Lender Party
and all of Lender Parties' obligations to US Borrower are terminated. All
statements and agreements contained in any certificate or other instrument
delivered by any Restricted Person to any Lender Party under any Loan Document
shall be deemed representations and warranties by US Borrower or agreements and
covenants of US Borrower under this Agreement. The representations, warranties,
indemnities, and covenants made by Restricted Persons in the US Loan Documents,
and the rights, powers, and privileges granted to Lender Parties in the US Loan
Documents, are cumulative, and, except for expressly specified waivers and
consents, no Loan Document shall be construed in the context of another to
diminish, nullify, or otherwise reduce the benefit to any Lender Party of any
such representation, warranty, indemnity, covenant, right, power or privilege.
In particular and without limitation, no exception set out in this Agreement to
any representation, warranty, indemnity, or covenant herein contained shall
apply to any similar representation, warranty, indemnity, or covenant contained
in any other Loan Document, and each such similar representation, warranty,
indemnity, or covenant shall be subject only to those exceptions which are
expressly made applicable to it by the terms of the various US Loan Documents.

      Section 10.3. Notices. All notices, requests, consents, demands and other
communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that US Agent may give telephonic notices to the other Lender Parties), and
shall be deemed sufficiently given or furnished if delivered by personal
delivery, by facsimile or other electronic transmission, by delivery service
with proof of delivery, or by registered or certified United States mail,
postage prepaid, to US Borrower and Restricted Persons at the address of US
Borrower specified on the signature pages hereto and to each Lender Party at its
address specified on Annex II hereto (unless changed by similar notice in
writing given by the particular Person whose address is to be changed). Any such
notice or communication shall be deemed to have been given (a) in the case of
personal delivery or delivery service, as of the date of first attempted
delivery during normal business hours at the address provided herein, (b) in the
case of facsimile or other electronic transmission, upon receipt, or (c) in the
case of registered or certified United States mail, three days after deposit in
the mail; provided, however, that no Borrowing Notice shall become effective
until actually received by US Agent.

      Section 10.4. Payment of Expenses; Indemnity.

      (a) Payment of Expenses. Whether or not the transactions contemplated by
this Agreement are consummated, US Borrower will promptly (and in any event,
within 30 days after any invoice or other statement or notice) pay: (i) all
reasonable costs and expenses incurred by or on behalf of US Agent (including
without limitation, attorneys' fees) in connection with (1) the negotiation,
preparation, execution and delivery of the US Loan Documents, and any and all
consents, waivers or other documents or instruments relating thereto, (2) the
borrowings hereunder and other action reasonably required in the course of
administration hereof, (3) monitoring or confirming (or preparation or
negotiation of any document related to) US Borrower's compliance with any
covenants or conditions contained in this Agreement or in any Loan Document, and
(ii) all reasonable costs and expenses incurred by or on behalf of any Lender

                                       49
<PAGE>

Party (including without limitation, attorneys' fees, consultants' fees and
accounting fees) in connection with the defense or enforcement of any of the US
Loan Documents (including this section) or the defense of any Lender Party's
exercise of its rights thereunder.

      (b) Indemnity. US Borrower agrees to indemnify each Agent-Related Person
and each Lender Party , upon demand, from and against any and all liabilities,
obligations, claims, losses, damages, penalties, fines, actions, judgments,
suits, settlements, costs, expenses or disbursements (including reasonable fees
of attorneys, accountants, experts and advisors) of any kind or nature
whatsoever (in this section collectively called "liabilities and costs") which
to any extent (in whole or in part) may be imposed on, incurred by, or asserted
against such Lender Party growing out of, resulting from or in any other way
associated with the US Loan Documents and the transactions and events (including
the enforcement or defense thereof) at any time associated therewith or
contemplated therein (whether arising in contract or in tort or otherwise and
including any violation or noncompliance with any Environmental Laws by any
Agent-Related Person or Lender Party or any other Person or any liabilities or
duties of any Agent-Related Person or Lender Party or any other Person with
respect to Hazardous Materials found in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT
ACT OR OMISSION OF ANY KIND BY ANY AGENT-RELATED PERSON OR LENDER PARTY,

provided only that no Agent-Related Person or Lender Party shall be entitled
under this section to receive indemnification for that portion, if any, of any
liabilities and costs which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment. If any
Person (including US Borrower or any of its Affiliates) ever alleges such gross
negligence or willful misconduct by any Lender Party, the indemnification
provided for in this section shall nonetheless be paid upon demand, subject to
later adjustment or reimbursement, until such time as a court of competent
jurisdiction enters a final judgment as to the extent and effect of the alleged
gross negligence or willful misconduct. As used in this section the term "Lender
Party" shall refer not only to each Person designated as such in Section 1.1 but
also to each director, officer, agent, attorney, employee, representative,
attorney-in-fact and Affiliate of such Person.

      Section 10.5. Parties in Interest. All grants, covenants and agreements
contained in the US Loan Documents shall bind and inure to the benefit of the
parties thereto and their respective successors and assigns; provided, however,
that, except as set forth in Section 13 of the Devon Financing ULC Guaranties,
no Restricted Person may assign or transfer any of its rights or delegate any of
its duties or obligations under any Loan Document without the prior consent of
all Lenders (and any attempted assignment or transfer by any Restricted Person
without such consent shall be null and void). Neither US Borrower nor any
Affiliates of US Borrower shall directly or indirectly purchase or otherwise
retire any Obligations owed to any Lender nor will any Lender

                                       50
<PAGE>

accept any offer to do so, unless each Lender shall have received substantially
the same offer with respect to the same Percentage Share of the Obligations owed
to it. If US Borrower or any Affiliate of US Borrower at any time purchases some
but less than all of the Obligations owed to all Lender Parties, such purchaser
shall not be entitled to any rights of any Lender under the US Loan Documents
unless and until US Borrower or its Affiliates have purchased all of the
Obligations.

      Section 10.6. Assignments and Participations.

      (a) Any Lender may at any time assign to one or more Eligible Assignees
all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Tranche A Note and its Percentage
Share of the Tranche A Facility Usage and the Tranche A Maximum Credit Amount,
and related rights and obligations under the US Loan Documents and/or its
Tranche B Note and its Percentage Share of the Tranche B Facility Usage and the
Tranche B Maximum Credit Amount and related rights and obligations under the US
Loan Documents); provided, however, that

            (i) each such assignment shall be to an Eligible Assignee;

            (ii) together with each such assignment of its rights and
      obligations relating to Tranche B Loans under this Agreement, such Lender
      shall assign the same Percentage Share of its rights and obligations under
      the Canadian Agreement to the same Eligible Assignee or an Affiliate of
      such Eligible Assignee.

            (iii) except in the case of such an assignment to another Lender or
      an assignment of all of a Lender's rights and obligations under this
      Agreement, any partial assignment of such Lender's rights and obligations
      under this Agreement and under the Canadian Agreement shall be in a
      collective amount at least equal to US $20,000,000 or an integral multiple
      of US $5,000,000 in excess thereof (in the case of the US Agreement
      calculated with respect to the Maximum US Credit Amount during the Tranche
      B Revolving Period and thereafter calculated with respect to the aggregate
      amount of the Tranche B Facility Usage and the Tranche A Maximum Credit
      Amount, and in the case of the Canadian Credit Agreement calculated with
      respect to the Canadian Maximum Credit Amount during the Canadian
      Revolving Period and thereafter calculated with respect to the Canadian
      Facility Usage);

            (iv) each such assignment by a Lender with respect to Tranche A
      Loans shall be of a constant, and not varying, percentage of all of its
      rights and obligations with respect to Tranche A Loans and Letters of
      Credit under the US Loan Documents and each such assignment by a Lender
      with respect to Tranche B Loans shall be of a constant, and not varying,
      percentage of all of its rights and obligations with respect to Tranche B
      Loans under the US Loan Documents and Canadian Loans under the Canadian
      Loan Documents; and

                                       51
<PAGE>

            (v) the parties to such assignment shall execute and deliver to US
      Agent for its acceptance an Assignment and Assumption in the form of
      Exhibit F hereto, together with any Note subject to such assignment and a
      processing fee of US $3,500.

Subject to acceptance and recording thereof by US Agent pursuant to subsection
(b) of this Section, from and after the effective date specified in each
Assignment and Assumption, the Eligible Assignee thereunder shall be a party to
this Agreement and, to the extent of the interest assigned by such Assignment
and Assumption, have the obligations, rights, and benefits of a Lender under
this Agreement and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 3.2, 3.6, 3.9, and 10.4). Upon the
consummation of any assignment pursuant to this section, the assignor, US Agent
and US Borrower shall make appropriate arrangements so that, if required, new US
Notes are issued to the assignor and the assignee. If the assignee is not
incorporated under the Laws of the United States of America or a state thereof,
it shall deliver to US Borrower and US Agent certification as to exemption from
deduction or withholding of Taxes in accordance with Section 3.10. Any
assignment or transfer by a Lender of rights or obligations under this Agreement
that does not comply with this subsection shall be treated for purposes of this
Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with subsection (d) of this Section.

      (b) US Agent, acting solely for this purpose as an agent of US Borrower,
shall maintain at its address referred to in Section 10.3 a copy of each
Assignment and Assumption delivered to and accepted by it and a register for the
recordation of the names and addresses of the Lenders and their Percentage Share
of the US Maximum Credit Amount of, and principal amount of the US Loans 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 US
Borrower, US 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,
notwithstanding notice to the contrary. The Register shall be available for
inspection by US Borrower or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

      (c) Upon its receipt of an Assignment and Assumption executed by the
parties thereto, together with any Note subject to such assignment and payment
of the processing fee, US Agent shall, if such Assignment and Assumption has
been completed and is in substantially the form of Exhibit F hereto, (i) accept
such Assignment and Assumption, (ii) record the information contained therein in
the Register and (iii) give prompt notice thereof to the parties thereto.

      (d) Any Lender may at any time, without the consent of, or notice to, US
Borrower or US Agent, sell participations to any Person (other than a natural
person or US Borrower or any of US Borrower's Affiliates or Subsidiaries) in all
or a portion of such Lender's rights and/or obligations under this Agreement
(including all or a portion of its US Maximum Credit Amount and its US Loans);
provided, however, that (i) such Lender's obligations under this Agreement

                                       52
<PAGE>

shall remain unchanged, (ii) such Lender shall remain solely responsible to the
other parties hereto for the performance of such obligations, (iii) the
participant shall be entitled to the benefit of the yield protection provisions
contained in Article III (provided that a participant shall not be entitled to
receive any greater payment under Section 3.1 or 3.2 than the applicable Lender
would have been entitled to receive with respect to the participation sold to
such participant, unless the sale of the participation to such participant is
made with US Borrower's prior written consent, and (iv) US Borrower, US 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. A participant that would have been subject to Section 3.9 if it were
a Lender, shall not be entitled to the benefits of Section 3.1 unless US
Borrower has been notified of the participation sold to such participant, and
such participant agrees, for the benefit of US Borrower, to comply with such
Section as if it were a Lender) and the right of offset contained in Section
6.14 (provided that such participant agrees to be subject to Section 9.8 as if
it were a Lender). Any agreement or instrument pursuant to which a Lender sells
such a participation shall provide that such Lender shall retain the sole right
to enforce this Agreement and to approve any amendment, modification, or waiver
of any provision of this Agreement (provided that such Lender may agree that it
will not approve amendments, modifications, or waivers decreasing the amount of
principal of or the rate at which interest is payable on such US Loans or Note,
extending any scheduled principal payment date or date fixed for the payment of
interest on such US Loans or Note, or extending its US Maximum Credit Amount
without the consent of the participant).

      (e) If the consent of US Borrower to an assignment to an Eligible Assignee
is required hereunder, US Borrower shall be deemed to have given its consent ten
(10) Business Days after the date notice thereof has been delivered by the
assigning Lender (through US Agent) unless such consent is expressly refused by
US Borrower prior to such tenth Business Day.

      (f) Notwithstanding anything to the contrary contained herein, if at any
time Bank of America assigns all of its Percentage Share in the Obligations and
its rights and obligations hereunder pursuant to subsection 10.6(a) above, Bank
of America may (i) upon 30 days' notice to US Borrower and the Lenders, resign
as US LC Issuer and/or (ii) upon 30 days' notice to US Borrower, resign as US
Swing Lender and/or terminate its commitment to make US Swing Loans. In the
event of any such resignation by Bank of America as US LC Issuer or US Swing
Lender or termination of its commitment to make US Swing Loans, US Borrower
shall be entitled to appoint from among the US Lenders a successor US LC Issuer
or US Swing Lender hereunder; provided, however, that no failure by US Borrower
to appoint any such successor shall affect the resignation of Bank of America as
US LC Issuer or US Swing Lender or termination of its commitment to make US
Swing Loans, as the case may be. If Bank of America resigns as US LC Issuer, it
shall retain all the rights and obligations of US LC Issuer hereunder with
respect to all Letters of Credit outstanding as of the effective date of its
resignation as US LC Issuer and all US LC Obligations with respect thereto
(including the right to require the Tranche A Lenders to make US Base Rate Loans
or fund participations in unreimbursed amounts pursuant to Section 2.3(b)). If
Bank of America resigns as US Swing Lender or terminates its commitment to make
US Swing Loans, it shall retain all the rights of US Swing Lender provided for
hereunder with respect to US Swing Loans made by it and outstanding as of the
effective date

                                       53
<PAGE>

of such termination, including the right to require the US Lenders to make
Tranche A Loans or fund participations in outstanding US Swing Loans pursuant to
Section 1.8.

      (g) Notwithstanding any other provision set forth in this Agreement, any
Lender may at any time assign and pledge all or any portion of its US Loans and
its Note to any Federal Reserve Bank as collateral security pursuant to
Regulation A and any Operating Circular issued by such Federal Reserve Bank. No
such assignment shall release the assigning Lender from its obligations
hereunder.

      (h) Any Lender may furnish any information concerning US Borrower or any
of its Subsidiaries in the possession of such Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject, however, to the provisions of Section 10.7 hereof.

      Section 10.7. Confidentiality. US Agent and each Lender (in this Section
each is called a "Lending Party") agrees to keep confidential any information
furnished or made available to it by US Borrower pursuant to this Agreement that
is marked confidential; provided that nothing herein shall prevent any Lending
Party from disclosing such information (a) to any other Lending Party or any
Affiliate of any Lending Party, or any officer, director, employee, US Agent, or
advisor of any Lending Party or Affiliate of any Lending Party, (b) to any other
Person if reasonably incidental to the administration of the credit facility
provided herein, (c) as required by any Law, rule, or regulation, (d) upon the
order of any court or administrative agency, (e) upon the request or demand of
any regulatory agency or authority, (f) that is or becomes available to the
public or that is or becomes available to any Lending Party other than as a
result of a disclosure by any Lending Party prohibited by this Agreement, (g) in
connection with any litigation to which such Lending Party or any of its
Affiliates may be a party, (h) to the extent necessary in connection with the
exercise of any remedy under this Agreement or any other Loan Document, and (i)
subject to provisions substantially similar to those contained in this section,
to any actual or proposed participant or assignee.

      Section 10.8. Governing Law; Submission to Process. Except to the extent
that the law of another jurisdiction is expressly elected in a Loan Document,
the US Loan Documents shall be deemed contracts and instruments made under the
laws of the State of Texas and shall be construed and enforced in accordance
with and governed by the laws of the State of Texas and the laws of the United
States of America, without regard to principles of conflicts of law. Chapter 346
of the Texas Finance Code (which regulates certain revolving credit loan
accounts and revolving tri-party accounts) does not apply to this Agreement or
to the US Notes. US Borrower hereby irrevocably submits itself and each other
Restricted Person to the non-exclusive jurisdiction of the state and federal
courts sitting in the State of Texas and agrees and consents that service of
process may be made upon it or any Restricted Person in any legal proceeding
relating to the US Loan Documents or the Obligations by any means allowed under
Texas or federal law.

      Section 10.9. Limitation on Interest. Lender Parties, Restricted Persons
and any other parties to the US Loan Documents intend to contract in strict
compliance with applicable usury

                                       54
<PAGE>

Law from time to time in effect. In furtherance thereof such Persons stipulate
and agree that none of the terms and provisions contained in the US Loan
Documents shall ever be construed to create a contract to pay, for the use,
forbearance or detention of money, interest in excess of the maximum amount of
interest permitted to be charged by applicable Law from time to time in effect.
Neither any Restricted Person nor any present or future guarantors, endorsers,
or other Persons hereafter becoming liable for payment of any Obligation shall
ever be liable for unearned interest thereon or shall ever be required to pay
interest thereon in excess of the maximum amount that may be lawfully charged
under applicable Law from time to time in effect, and the provisions of this
section shall control over all other provisions of the US Loan Documents which
may be in conflict or apparent conflict herewith. Lender Parties expressly
disavow any intention to charge or collect excessive unearned interest or
finance charges in the event the maturity of any Obligation is accelerated. If
(a) the maturity of any Obligation is accelerated for any reason, (b) any
Obligation is prepaid and as a result any amounts held to constitute interest
are determined to be in excess of the legal maximum, or (c) any Lender or any
other holder of any or all of the Obligations shall otherwise collect moneys
which are determined to constitute interest which would otherwise increase the
interest on any or all of the Obligations to an amount in excess of that
permitted to be charged by applicable Law then in effect, then all sums
determined to constitute interest in excess of such legal limit shall, without
penalty, be promptly applied to reduce the then outstanding principal of the
related Obligations or, at such Lender's or holder's option, promptly returned
to US Borrower or the other payor thereof upon such determination. In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable Law, Lender
Parties and Restricted Persons (and any other payors thereof) shall to the
greatest extent permitted under applicable Law, (i) characterize any
non-principal payment as an expense, fee or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable Law in order to
lawfully charge the maximum amount of interest permitted under applicable Law.
In the event applicable Law provides for an interest ceiling under Chapter 303
of the Texas Finance Code (the "Texas Finance Code") as amended, for that day,
the ceiling shall be the "weekly ceiling" as defined in the Texas Finance Code;
provided that if any applicable Law permits greater interest, the Law permitting
the greatest interest shall apply. As used in this section the term "applicable
Law" means the Laws of the State of Texas or the Laws of the United States of
America, whichever Laws allow the greater interest, as such Laws now exist or
may be changed or amended or come into effect in the future.

      Section 10.10. Termination; Limited Survival. In its sole and absolute
discretion US Borrower may at any time that no Obligations are owing elect in a
written notice delivered to US Agent to terminate this Agreement. Upon receipt
by US Agent of such a notice, if no Obligations are then owing this Agreement
and all other US Loan Documents shall thereupon be terminated and the parties
thereto released from all prospective obligations thereunder. Notwithstanding
the foregoing or anything herein to the contrary, any waivers or admissions made
by any Restricted Person in any Loan Document, any Obligations under Sections
3.2 through 3.6, and any obligations which any Person may have to indemnify or
compensate any Lender Party shall

                                       55
<PAGE>

survive any termination of this Agreement or any other Loan Document. At the
request and expense of US Borrower, US Agent shall prepare and execute all
necessary instruments to reflect and effect such termination of the US Loan
Documents. US Agent is hereby authorized to execute all such instruments on
behalf of all Lenders, without the joinder of or further action by any Lender.

      Section 10.11. Severability. If any term or provision of any Loan Document
shall be determined to be illegal or unenforceable all other terms and
provisions of the US Loan Documents shall nevertheless remain effective and
shall be enforced to the fullest extent permitted by applicable Law.

      Section 10.12. Counterparts; Fax. This Agreement may be separately
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to
constitute one and the same Agreement. This Agreement and the US Loan Documents
may be validly executed and delivered by facsimile or other electronic
transmission.

      Section 10.13. Waiver of Jury Trial, Punitive Damages, etc. US BORROWER
AND EACH LENDER PARTY HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND
IRREVOCABLY (A) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH
THE US LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED
THEREWITH, BEFORE OR AFTER MATURITY, IN EACH CASE WHETHER NOW EXISTING OR
HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND
EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR
CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY
PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY, (B) WAIVES, TO THE MAXIMUM
EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY
SUCH LITIGATION ANY "SPECIAL DAMAGES", AS DEFINED BELOW, (C) CERTIFIES THAT NO
PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN
THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (D)
ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER US
LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG
OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION.
AS USED IN THIS SECTION, "SPECIAL DAMAGES" INCLUDES ALL SPECIAL, CONSEQUENTIAL,
EXEMPLARY, OR PUNITIVE DAMAGES (REGARDLESS OF HOW NAMED), BUT DOES NOT INCLUDE
ANY PAYMENTS OR FUNDS WHICH ANY PARTY HERETO HAS EXPRESSLY PROMISED TO PAY OR
DELIVER TO ANY OTHER PARTY HERETO.

      Section 10.14. Defined Terms. Capitalized terms and phrases used and not
otherwise defined herein shall for all purposes of this Agreement have the

                 AMENDED AND RESTATED CANADIAN CREDIT AGREEMENT

      THIS AMENDED AND RESTATED CANADIAN CREDIT AGREEMENT (this "Agreement") is
made as of June 7, 2002, by and among Northstar Energy Corporation, an Alberta
corporation, and Devon Canada Corporation, an Alberta corporation (herein
collectively, called "Canadian Borrowers"), Bank of America, N.A., acting
through its Canadian Branch, individually and as administrative agent (herein
called "Canadian Agent"), and the Lenders party to, and as defined under, the
Existing Canadian Agreement (as defined below).

      Canadian Borrowers, Canadian Agent and Canadian Lenders entered into the
Canadian Credit Agreement dated as of August 29, 2000 (as amended, supplemented
or otherwise modified prior to the Closing Date as defined herein, the "Existing
Canadian Agreement"), for the purpose and consideration therein expressed,
wherein Canadian Lenders became obligated to make loans to Canadian Borrowers as
therein provided.

      Canadian Borrowers have requested that Canadian Lenders extend the
effectiveness of the Canadian Revolving Period as set forth in the Existing
Canadian Agreement and make certain other amendments and modifications thereto,
all on the terms and conditions provided herein.

      Accordingly, in consideration of the loans which may hereafter be made by
Canadian Lenders to Canadian Borrowers, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
Canadian Borrowers, Canadian Agent and Canadian Lenders hereby agree as follows:

                          ARTICLE I - Canadian Advances

      Section 1.1. Commitments to Make Advances; Canadian Notes.

      (a) Canadian Loans. Subject to the terms and conditions hereof, each
Lender agrees to extend credit to each Canadian Borrower by advancing funds to
the applicable Canadian Borrower specified in a Borrowing Notice (herein called
such Lender's "Canadian Revolving Loans" and, with reference to Canadian
Resident Lenders only, accepting or purchasing drafts of Bankers' Acceptances
issued under this Agreement by the applicable Canadian Borrower specified in a
Borrowing Notice herein called such Lender's "Bankers' Acceptances"; each
Lender's Canadian Revolving Loans, Canadian Term Loans, and Bankers' Acceptances
are herein collectively called such Lender's "Canadian Advances") upon the
applicable Canadian Borrower's request from time to time during the Canadian
Revolving Period, provided that (i) subject to Sections 2.1, 2.2., 3.3, 3.4 and
3.5, all Lenders are requested to make Canadian Advances of the same Type in
accordance with their respective Percentage Shares and as part of the same
Borrowing, (ii) such Lender's Percentage Share of the Canadian Facility Usage
shall never exceed such Lender's Percentage Share of the Canadian Maximum Credit
Amount, and (iii) the aggregate amount of the Canadian Facility Usage and the
Canadian Swing Loans outstanding shall never
<PAGE>
exceed the Canadian Maximum Credit Amount. Subject to the terms and conditions
hereof, each Lender also agrees to extend credit to each Canadian Borrower by
participating in draws under Letters of Credit in accordance with Sections 2.6,
2.7 and 2.8 hereof. The aggregate amount of all Canadian Loans in any Borrowing
must be an integral multiple of $100,000 in the Applicable Currency which equals
or exceeds $1,000,000 in the Applicable Currency or must equal the unadvanced
portion of the Canadian Maximum Credit Amount. Each Canadian Borrower may have
no more than ten Borrowings of Eurodollar Loans outstanding at any time. The
obligation of each Canadian Borrower to repay to each Lender the aggregate
amount of all Canadian Loans (excluding Canadian Swing Loans) made by such
Lender to such Borrower, together with interest accruing in connection
therewith, shall be evidenced by a separate promissory note (herein called such
Lender's "Canadian Note") made, by each Canadian Borrower payable to the order
of such Lender in the form of Exhibit A-1 with appropriate insertions. The
amount of principal owing on any Lender's Canadian Note at any given time shall
be the aggregate amount of all Canadian Loans theretofore made by such Lender
minus all payments of principal theretofore received by such Lender on such
Canadian Note. Interest on each Canadian Note shall accrue and be due and
payable as provided herein and therein. Each Lender's Canadian Note shall be due
and payable as provided herein and therein and shall be due and payable in full
on the Canadian Facility Maturity Date.

      (b) Swing Loans. Subject to the terms and conditions hereof, Canadian
Swing Lender agrees to make loans to each Canadian Borrower (herein called
"Canadian Swing Loans") upon the applicable Canadian Borrower's request from
time to time during the Canadian Revolving Period, provided that (i) the
Canadian Facility Usage shall never exceed the Canadian Maximum Credit Amount,
and (ii) the aggregate amount of Canadian Swing Loans outstanding shall never
exceed the Canadian Swing Sublimit. The aggregate amount of all Canadian Swing
Loans in any Borrowing must be an integral multiple of C $100,000 which equals
or exceeds C $1,000,000 or must equal the unadvanced portion of the Canadian
Maximum Credit Amount. The obligation of each Canadian Borrower to repay to
Canadian Swing Lender the aggregate amount of all Canadian Swing Loans made by
Canadian Swing Lender, together with interest accruing in connection therewith,
shall be evidenced by a separate promissory note (herein called each Canadian
Borrower's "Canadian Swing Note") made by each Canadian Borrower payable to the
order of Canadian Swing Lender in the form of Exhibit A-2 with appropriate
insertions. The amount of principal owing on each Canadian Swing Note at any
given time shall be the aggregate amount of all Canadian Swing Loans theretofore
made by Canadian Swing Lender minus all payments of principal theretofore
received by Canadian Swing Lender on such Canadian Swing Note (including as a
result of any refinancing pursuant to Section 1.11). Interest on each Canadian
Swing Note shall accrue and be due and payable as provided herein and therein.
Each Canadian Swing Note shall be due and payable as provided herein and
therein, and shall be due and payable in full on the Canadian Conversion Date.
Subject to the terms and conditions hereof, each Canadian Borrower may borrow,
repay, and reborrow Canadian Swing Loans under the Canadian Agreement during the
Canadian Revolving Period. The Canadian Swing Lender shall be a Canadian
Resident Lender.

      (c) Overterm Canadian Loans are Separate Loans. Any Overterm Canadian
Loans shall be separate and distinct loans with their own independent repayment
terms and conditions as

                                       2
<PAGE>
set forth in this Canadian Agreement. Such loans shall be separate and distinct
from each other and from any Canadian Revolving Loans and Canadian Term Loans
into which such Canadian Revolving Loans may be converted. The parties hereto
further acknowledge and agree that any Canadian Term Loans established upon the
conversion of the Canadian Revolving Loans shall be a continuation of any such
Canadian Revolving Loans and shall not be separate and distinct from any such
Canadian Revolving Loans.

      Section 1.2. Requests for New Canadian Advances. The applicable Canadian
Borrower must give to Canadian Agent written notice (or telephonic notice
promptly confirmed in writing) of any requested Borrowing of new Canadian Loans
and any requested Borrowing by way of new Bankers' Acceptances. Each such notice
constitutes a "Borrowing Notice" hereunder and must:

      (a) specify (i) the aggregate amount of any such Borrowing of new Canadian
Base Rate Loans and the date on which such Canadian Base Rate Loans are to be
advanced, (ii) the aggregate amount of any such Borrowing of Canadian Prime Rate
Loans and the date on which such Canadian Prime Rate Loans are to be advanced,
(iii) the aggregate amount of any such Borrowing of new US Dollar Eurodollar
Loans, the date on which such US Dollar Eurodollar Loans are to be advanced

apply thereto), and the length of the applicable Eurodollar Interest Period,
(iv) the aggregate amount of any such Borrowing of new Canadian Dollar
Eurodollar Loans, the date on which such Canadian Dollar Eurodollar Loans are to
be advanced (which shall be the first day of the Eurodollar Interest Period
which is to apply thereto), and the length of the applicable Eurodollar Interest
Period, (v) the aggregate amount of any such Borrowing by way of Bankers'
Acceptances (subject to Section 2.2(f)), and the date on which such Bankers'
Acceptances are to be accepted and the maturity of such Bankers' Acceptances, or

the date on which such Canadian Swing Loans are to be advanced; and

      (b) be received by Canadian Agent (i) in the case of Canadian Advances
other than Canadian Swing Loans, not later than 11:00 a.m., Toronto, Ontario
time, on (1) on the Business Day preceding the day on which any such Canadian
Base Rate Loans or Canadian Prime Rate Loans are to be made, (2) the third
Business Day preceding the day on which any such Eurodollar Loans are to be made
or (3) the third Business Day before such Bankers' Acceptances are to be issued
and (ii) in the case of Canadian Advances that are Canadian Swing Loans, not
later than 2:00 p.m., Toronto, Ontario time on the Business Day on which any
such Canadian Swing Loans are to be made.

Each such written request or confirmation must be made in the form and substance
of the "Borrowing Notice" attached hereto as Exhibit B, duly completed. Each
such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by the applicable Canadian Borrower as to the
matters which are required to be set out in such written confirmation. Upon
receipt of any such Borrowing Notice, Canadian Agent shall give each Lender
prompt notice of the terms thereof (excluding Canadian Swing Loans) not later
than 5:00 p.m. Toronto, Ontario time on the day it receives such Borrowing
Notice from the applicable

                                       3
<PAGE>
Canadian Borrower if it receives such Borrowing Notice by 11:00 a.m., Toronto,
Ontario time, otherwise on the next Business Day. Each Borrowing Notice shall be
irrevocable and binding on the applicable Canadian Borrower. If all conditions
precedent to such new Canadian Advances have been met, (i) each Lender will on
the date requested promptly remit to Canadian Agent by 1:00 p.m. Toronto,
Ontario time its Canadian Advances made in Canadian Dollars to Canadian Agent's
office in Toronto, Canada and its Canadian Advances made in United States
Dollars to the US Account in New York, New York) in immediately available funds,
and upon receipt of such funds, unless to its actual knowledge any conditions
precedent to such Canadian Advances have been neither met nor waived as provided
herein, Canadian Agent shall promptly make such Canadian Advances available to
the applicable Canadian Borrower or (ii) each Canadian Resident Lender will
accept drafts of Bankers' Acceptances on the date requested in accordance with
Sections 2.1 through 2.3. Unless Canadian Agent shall have received prompt
notice from a Lender that such Lender will not make available to Canadian Agent
such Lender's new Canadian Advance, Canadian Agent may in its discretion assume
that such Lender has made such Canadian Advance available to Canadian Agent in
accordance with this section and Canadian Agent may if it chooses, in reliance
upon such assumption, make such Canadian Advance available to the applicable
Canadian Borrower. If and to the extent such Lender shall not so make its new
Canadian Advance available to Canadian Agent, such Lender and the applicable
Canadian Borrower severally agree to pay or repay to Canadian Agent within three
days after demand the amount of such Canadian Advance together with interest
thereon, for each day from the date such amount was made available to the
applicable Canadian Borrower until the date such amount is paid or repaid to
Canadian Agent, with interest at (1) the Canadian Prime Rate, if such Lender is
making such payment and (2) the interest rate applicable at the time to the
other new Canadian Advances made on such date, if a Canadian Borrower is making
such repayment; provided that Canadian Agent gave notice of the terms of the
Borrowing Notice to such Lender in accordance with the terms of this Section
1.2. If neither such Lender nor such Canadian Borrower pays or repays to
Canadian Agent such amount within such three-day period, Canadian Agent shall in
addition to such amount be entitled to recover from such Lender and from the
applicable Canadian Borrower, on demand, interest on such Canadian Advance at
the Default Rate applicable thereto, calculated from the date such amount was
made available to such Canadian Borrower. The failure of any Lender to make any
new Canadian Advance to be made by it hereunder shall not relieve any other
Lender of its obligation hereunder, if any, to make its new Canadian Advance,
but no Lender shall be responsible for the failure of any other Lender to make
any new Canadian Advance to be made by such other Lender.

      Section 1.3. Continuations and Conversions of Existing Canadian Advances.
Subject to the terms of Section 2.3 with respect to Bankers' Acceptances, the
applicable Canadian Borrower may make the following elections with respect to
Canadian Advances and Canadian Swing Loans already outstanding under this
Agreement: (i) to convert any Type of Canadian Advance to any other Type of
Canadian Advance, provided that any such Conversion of any Eurodollar Loan must
be made on the last day of the Eurodollar Interest Period applicable thereto and
any such Conversion of a Bankers' Acceptance must be made on the date of
maturity thereof; (ii) to continue Eurodollar Loans beyond the expiration of
such Eurodollar Interest Period by designating a new Eurodollar Interest Period
to take effect at the time of such expiration, and to rollover any

                                       4
<PAGE>
existing Bankers' Acceptance by designating the new maturity date applicable
thereto; (iii) to convert Canadian Swing Loans to any Type of Canadian Advances
as a refinancing of such Canadian Swing Loans pursuant to Section 1.11; and (iv)
to continue or convert Overterm Canadian Loans to any Type of Canadian Advances.
In making such elections, the applicable Canadian Borrower may combine existing
Canadian Advances made pursuant to separate Borrowings into one new Borrowing or
divide existing Canadian Advances made pursuant to one Borrowing into separate
new Borrowings, provided that Canadian Borrowers may have no more than ten
Borrowings of US Dollar Eurodollar Loans outstanding at any time and no more
than ten Borrowings of Canadian Dollar Eurodollar Loans outstanding at any time,
provided further that Canadian Advances that are Overterm Canadian Loans may not
be combined with any other Canadian Advances that are Canadian Term Loans. To
make any such election, the applicable Canadian Borrower must give to Canadian
Agent written notice (or telephonic notice promptly confirmed in writing) of any
such Conversion or Continuation of existing Canadian Advances, with a separate
notice given for each new Borrowing. Each such notice constitutes a
"Continuation/Conversion Notice" hereunder and must:

      (a) specify the existing Canadian Advances made under this Agreement which
are to be continued or converted;

      (b) specify (i) the aggregate amount of any Borrowing of Canadian Base
Rate Loans or Canadian Prime Rate Loans into which such existing Canadian
Advances are to be continued or converted and the date on which such
Continuation or Conversion is to occur, or (ii) the aggregate amount of any
Borrowing of Eurodollar Loans into which such existing Canadian Advances are to
be continued or converted, the date on which such Continuation or Conversion is
to occur (which shall be the first day of the Eurodollar Interest Period which
is to apply to such Eurodollar Loans), and the length of the applicable
Eurodollar Interest Period, or (iii) the amount of any Borrowing of Bankers'
Acceptances into which such existing Canadian Advances are to be continued or
converted, the date on which such Continuation or Conversion is to occur, and
the maturity of such Bankers' Acceptances; and

      (c) be received by Canadian Agent not later than 11:00 a.m., Toronto,
Ontario time, on (i) the first Business Day preceding the day on which any such
Continuation or Conversion to Canadian Base Rate Loans or Canadian Prime Rate
Loans is to occur, or (ii) the third Business Day preceding the day on which any
such Continuation or Conversion to Eurodollar Loans is to occur, or (iii) on the
third Business Day preceding the day on which any such Continuation or
Conversion to Bankers' Acceptances is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by the applicable Canadian Borrower as to
the matters which are required to be set out in such written confirmation. Upon
receipt of any such Continuation/Conversion Notice, Canadian Agent shall give
each Lender prompt notice of the terms thereof. Each Continuation/Conversion
Notice shall be irrevocable and binding on the applicable Canadian Borrower.
During the continuance of any Default, Canadian Borrowers may not make any
election to convert existing Canadian

                                       5
<PAGE>
Advances or Canadian Swing Loans made under this Agreement into Eurodollar Loans
or Bankers' Acceptances or continue existing Eurodollar Loans made under this
Agreement as Eurodollar Loans or to rollover existing Bankers' Acceptances into
new Bankers' Acceptances. If (due to the existence of a Default or for any other
reason) the applicable Canadian Borrower fails to timely and properly give or
are prevented hereunder from giving any Continuation/Conversion Notice with
respect to a Borrowing of existing Eurodollar Loans or Bankers' Acceptances at
least three days prior to the end of the Eurodollar Interest Period applicable
thereto or maturity of the Bankers' Acceptance, such Eurodollar Loans and
Bankers' Acceptances shall automatically be converted into Canadian Base Rate
Loans (in the case of US Dollar Eurodollar Loans) or Canadian Prime Rate Loans
(in the case of Canadian Dollar Eurodollar Loans and Bankers' Acceptances) at
the end of such Eurodollar Interest Period. No new funds shall be repaid by the
applicable Canadian Borrower or advanced by any Lender in connection with any
Continuation or Conversion of existing Canadian Advances pursuant to this
section, and no such Continuation or Conversion shall be deemed to be a new
advance of funds for any purpose; such Continuations and Conversions merely
constitute a change in terms of already outstanding Advances and the interest
rate applicable thereto.

      Section 1.4. Repayments.

      (a) During Canadian Revolving Period. Subject to the terms and conditions
hereof, either Canadian Borrower may borrow, repay, and reborrow hereunder

      3.6, and provided that no Bankers' Acceptance may be prepaid prior to its
      stated maturity date except in accordance with Section 2.5. Each

      accrued and unpaid on the principal so prepaid, shall be in addition to,
      and not in lieu of, all payments otherwise required to be paid under the
      Canadian Loan Documents at the time of such prepayment, and shall first
      reduce the semi-annual scheduled installments (other than the final
      installment) during the Term Period in respect of Canadian Loans that are
      not Competitive Bid Loans, then reduce the final installment in respect of
      Canadian Loans that are not Competitive Bid Loans or Overterm Canadian
      Loans, and then, unless otherwise designated by Canadian Borrowers, reduce
      the outstanding Competitive Bid Loans in order of shortest maturity. Each
      prepayment of principal under this section in respect of Overterm Canadian
      Loans shall be accompanied by all interest then accrued and unpaid on the
      principal so prepaid, shall be in addition to, and not in lieu of, all
      payments otherwise required to be paid under the Canadian Loan Documents
      at the time of such prepayment, and shall first reduce the semi-annual
      scheduled installments (other than the final installment) during the Term
      Period in respect of Overterm Canadian Loans, and then reduce the final
      installment in respect of such Overterm Canadian Loans.

            (ii) Scheduled Repayments of Principal. Subject to Section
      1.4(b)(iii) during the Term Period, the applicable Canadian Borrower shall
      repay the principal of the Canadian Loans that are not Competitive Bid

      in an amount equal to two and one-half percent (2.5%) of the outstanding
      principal balance of the Canadian Advances on the Canadian Conversion
      Date. Such installments shall be due and payable on each June 30 and
      December 31 each year and in a final installment due and payable on the
      Canadian Facility Maturity Date in an amount equal to the entire unpaid
      principal balance of such Loans outstanding on the Canadian Facility
      Maturity Date.

            (iii) Scheduled Repayments of Overterm Canadian Loans. From and
      after the date any Overterm Canadian Loan arises, the applicable Canadian
      Borrower shall repay the principal of the Overterm Canadian Loans in
      semi-annual installments, each in an amount equal to two and one-half
      percent (2.5%) of the outstanding aggregate principal balance of the
      Overterm Canadian Loans on the date of each such semi-annual installment.
      Such installments shall be due and payable on each June 30 and December 31
      each year and in a final installment due and payable on the Canadian
      Facility Maturity Date in an amount equal to the entire unpaid principal
      balance of such Overterm Canadian Loans outstanding on the Canadian
      Facility Maturity Date.

            (iv) Income Tax Act (Canada). Except as otherwise provided in
      Section 8.1 and except in the case of Overterm Canadian Loans, in no event
      shall either Canadian Borrower be required to repay more than 25% of the
      principal amount (for the purposes of subparagraph 212(1)(b)(vii) of the
      Income Tax Act (Canada)) of the Canadian

                                       7
<PAGE>
      Advances made to it prior to five years and a day after the Canadian
      Conversion Date, including, but not limited to payments under
      Section 1.4(b)(ii), 1.4(c) and 1.4(d).

      (c) Mandatory Prepayments. Except to the extent permitted by Section
1.4(d), and subject to Sections 1.4(b)(iv) and 1.4(e), if the aggregate
principal amount of the outstanding Canadian Obligations ever exceeds the
Canadian Maximum Credit Amount, Canadian Borrowers shall immediately prepay the
principal of the Canadian Loans outstanding under the Canadian Agreement in an
amount at least equal to such excess. Each prepayment of principal under this
section shall be accompanied by all interest then accrued and unpaid on the
principal so prepaid. Any principal or interest prepaid pursuant to this section
shall be in addition to, and not in lieu of, all payments otherwise required to
be paid under the Canadian Loan Documents at the time of such prepayment.

      (d) Currency Fluctuations. Notwithstanding any other provision of this
Agreement, if any Canadian Loan outstanding is denominated in C$, Canadian Agent
shall have the right to calculate the outstanding Canadian Obligations for all
purposes including making a determination from time to time of the available
undrawn portion of the Canadian Maximum Credit Amount. If following such
calculation, Canadian Agent determines that the outstanding Canadian Obligations
are greater than 105% of the Canadian Advances permitted hereby to be
outstanding at such time, then Canadian Agent shall so advise Canadian Borrowers
and, subject to Sections 1.4(b)(iv) and 1.4(e), Canadian Borrowers shall repay,
on the later of five Business Days after such advice and the next applicable
Interest Payment Date immediately following such date of calculation, an amount
sufficient to eliminate the excess over and above the aggregate amount of the
Canadian Loans permitted hereby to be outstanding at such time, together with
all accrued interest on the amount so paid.

      (e) Application of Prepayment. Any mandatory prepayment of any principal
amount (for the purposes of this Section, and as used in subparagraph
212(1)(b)(vii) of the Income Tax Act (Canada)) made by a Canadian Borrower
pursuant to Sections 1.4(c) and 1.4(d) or otherwise in respect of a particular
loan, shall reduce the semi-annual scheduled installments (other than the final
installment) during the Term Period in respect of that loan in inverse order of
maturity. Such mandatory prepayments shall be applied to the Canadian Loans pro
rata based on outstanding principal; provided that if the amount of any
mandatory prepayment obligation is in excess of the amount of any remaining
semi-annual scheduled installments, the excess amount shall be paid by the
applicable Canadian Borrower as part of the final scheduled installment on the
Canadian Facility Maturity Date; and provided further that if any mandatory
prepayment relates to outstanding Bankers' Acceptances, the amount of such
mandatory prepayment shall be paid into the escrow fund maintained in accordance
with Section 2.5 until the maturity date of such outstanding Bankers'
Acceptances.

      Section 1.6. Extension of Canadian Conversion Date.

      (a) Canadian Borrowers may, at their option and from time to time during
the Canadian Revolving Period, request an offer to extend the Canadian Revolving
Period by delivering to Canadian Agent a Request for an Offer of Extension not
more than sixty days and not less than thirty days prior to the then current
Canadian Conversion Date. Canadian Agent shall forthwith provide a copy of the
Request for an Offer of Extension to each of the Lenders. Upon receipt from
Canadian Agent of an executed Request for an Offer of Extension, each

                                       10
<PAGE>
Lender shall, within twenty days after the date of such Lender's receipt of such
request from Canadian Agent, either:

            (i) notify Canadian Agent of its acceptance of the Request for an
      Offer of Extension, and the terms and conditions, if any, upon which such
      Lender is prepared to extend the Canadian Conversion Date; or

            (ii) notify Canadian Agent that the Request for an Offer of
      Extension has been denied, such notice to forthwith be forwarded by
      Canadian Agent to Canadian Borrowers to allow Canadian Borrowers to seek a
      replacement lender pursuant to Section 1.8 (any Lender giving notice of
      such denial is herein called a "Non-Accepting Lender"). The failure of a
      Lender to so notify Canadian Agent within such twenty day period shall be
      deemed to be notification by such Lender to Canadian Agent that such
      Lender has denied Canadian Borrowers' Request for an Offer of Extension.

      (b) Provided that all Lenders provide notice to Canadian Agent under
Section 1.6(a) that they accept the Request for an Offer of Extension, or if
there are Non-Accepting Lenders, such Lenders shall have been repaid pursuant to
Section 1.8 or replacement lenders shall have become parties hereto pursuant to
Section 1.8 and shall have accepted the Request for an Offer of Extension, such
acceptance having common terms and conditions, Canadian Agent shall deliver to
Canadian Borrowers an Offer of Extension incorporating the said terms and
conditions. Such offer shall be open for acceptance by Canadian Borrowers until
the fifth Business Day immediately preceding the then current Canadian
Conversion Date. Upon written notice by Canadian Borrowers to Canadian Agent
accepting an outstanding Offer of Extension and agreeing to the terms and
conditions, if any, specified therein (the date of such notice of acceptance in
Section 1.6 and 1.8 being called the "Extension Date"), the Canadian Conversion
Date shall be extended to the date 364 days from the Extension Date and the
terms and conditions specified in such Offer of Extension shall be immediately
effective.

      (c) Canadian Borrowers understand that the consideration of any Request
for an Offer of Extension constitutes an independent credit decision which each
Lender retains the absolute and unfettered discretion to make and that no
commitment in this regard is hereby given by a Lender and that any offer to
extend the Canadian Conversion Date may be on such terms and conditions in
addition to those set out herein as the extending Lenders stipulate.

      Section 1.7. Conversion to Canadian Term Loan. Unless there is an
extension of the Canadian Revolving Period in accordance with Section 1.6,
effective at 11:59 p.m. Toronto, Ontario time on the day immediately preceding
the Canadian Conversion Date, and provided that no Event of Default shall have
occurred and be continuing, (i) each Lender's obligation to make new Canadian
Advances, Canadian Swing Lender's obligation to make new Canadian Swing Loans,
and Canadian LC Issuer's obligation to issue Letters of Credit hereunder shall
be canceled automatically, and (ii) each Lender's Canadian Loans shall become
term Canadian Loans ("Canadian Term Loans") maturing on the Canadian Facility
Maturity Date.

      Section 1.8. Non-Accepting Lender. Provided that Canadian Required Lenders
provide notice to Agent under Section 1.6(a) that they accept the Request for an
Offer of Extension, on notice of Canadian Borrowers to Agent, Canadian Borrowers
shall be entitled to choose any of the following in respect of each
Non-Accepting Lender prior to the expiration of the Canadian Revolving Period,
provided that if Canadian Borrowers do not make an election prior to the
expiration of the Canadian Revolving Period, Canadian Borrowers shall be deemed
to have irrevocably elected to exercise the provisions of Section 1.8(b)(ii):

      (a) (i) the Non-Accepting Lender's obligations to make Canadian Advances
shall be canceled as of the Extension Date, the Canadian Maximum Credit Amount
shall be reduced by the amount so canceled, and on or prior to the Extension
Date the Canadian Borrowers shall repay in full all Canadian Obligations then
outstanding to the Non-Accepting Lender (as defined in Section 1.6(a)(ii)) , or
(ii) replace the Non-Accepting Lender by reaching satisfactory arrangements with
one or more existing Lenders or new Lenders, for the purchase, assignment and
assumption of all Canadian Obligations and US Obligations of the Non-Accepting
Lender, provided that any new Lender, with, if necessary, any Affiliate, shall
take a pro rata assignment of both Canadian Obligations and US Obligations, and
such Non-Accepting Lender shall be obligated to sell such Obligations in
accordance with such satisfactory arrangements; or

      (b) Canadian Borrowers may elect to revoke and cancel the Request for an
Offer of Extension by giving notice of such revocation and cancellation to Agent
(which shall promptly notify the Lenders thereof), and concurrently therewith,
shall have the option to (i) cancel the obligations of Lenders under the
Canadian Agreement and, subject to the notice requirements set forth in Section
1.6(a) and to the provisions of Article III, repay in full all Canadian
Obligations, or (ii) have the outstanding Canadian Loans that are not
Competitive Bid Loans on the Canadian Conversion Date become term loans as
provided in Section 1.7.

In connection with any such replacement of a Lender Party pursuant to this
Section 1.8, the applicable Canadian Borrower shall pay all costs that would
have been due to such Lender Party pursuant to Section 3.6 if such Lender
Party's Canadian Advances had been prepaid at the time of such replacement.

      Section 1.9. Competitive Bid Loans.

      (a) Either Canadian Borrower may request that each Canadian Resident
Lender submit Competitive Bids (on a several basis) for requested maturities of
thirty days or more to the applicable Canadian Borrower on any Business Day
during the Canadian Revolving Period, provided that all Canadian Resident
Lenders are requested to make a Competitive Bid on the same basis at the same
time. In order to request Competitive Bids, the applicable Canadian Borrower
shall deliver by hand or facsimile to Canadian Agent a Competitive Bid Request,
to be received by Canadian Agent not later than 9:00 a.m., Toronto, Ontario time
one Business Day before the date specified for a proposed Competitive Bid Loan.
A Competitive Bid Request that does not conform substantially to the format of
Exhibit I may be rejected in Canadian Agent's sole discretion, and Canadian
Agent shall promptly notify the applicable Canadian Borrower of such

                                       12
<PAGE>
rejection by facsimile. After receiving an acceptable Competitive Bid Request,
Canadian Agent shall no later than 12:00 noon, Toronto, Ontario time on the date
such Competitive Bid Request is received by Canadian Agent, by facsimile deliver
to Canadian Resident Lenders an Invitation to Bid substantially in the form of
Exhibit J with respect thereto.

      (b) Each Canadian Resident Lender may, in its sole discretion, make one or
more Competitive Bids to Canadian Agent responsive to each Competitive Bid
Request given by the applicable Canadian Borrower. Each Competitive Bid by a
Canadian Resident Lender must be received by Canadian Agent by facsimile not
later than 9:00 a.m., Toronto, Ontario time on the date specified for a proposed
Competitive Bid Loan. Multiple bids may be accepted by Canadian Agent.
Competitive Bids that do not conform substantially to the format of Exhibit K
may be rejected by Canadian Agent after conferring with, and upon the
instruction of, the applicable Canadian Borrower, and Canadian Agent shall
notify the bidding Canadian Resident Lender of such rejection as soon as
practicable. If any Canadian Resident Lender shall elect not to make a
Competitive Bid, such Canadian Resident Lender shall so notify Canadian Agent by
facsimile not later than 9:00 a.m., Toronto, Ontario time, on the date specified
for a Competitive Bid Loan; provided, however, that failure by any Canadian
Resident Lender to give such notice shall not cause such Canadian Resident
Lender to be obligated to make any Competitive Bid Loan and by such failure such
Lender shall be deemed to have rejected such Competitive Bid. A Competitive Bid
submitted by a Canadian Resident Lender shall be irrevocable.

      (c) Promptly, and in no event later than 9:30 a.m., Toronto, Ontario time,
on the date specified for a proposed Competitive Bid Loan, Canadian Agent shall
notify the applicable Canadian Borrower by facsimile of all the Competitive Bids
made, the Competitive Bid Rate and the principal amount of each Competitive Bid
Loan in respect of which a Competitive Bid was made, and the identity of each
Canadian Resident Lender that made each Competitive Bid. Canadian Agent shall
send a copy of all Competitive Bids to the applicable Canadian Borrower for its
records as soon as practicable after completion of the bidding process.

      (d) The applicable Canadian Borrower may, subject only to the provisions
hereof, accept or reject any Competitive Bid. The applicable Canadian Borrower
shall notify Canadian Agent by facsimile pursuant to a Competitive Bid
Accept/Reject Letter whether and to what extent the applicable Canadian Borrower
has decided to accept or reject any or all of the Competitive Bids, not later
than 10:00 a.m., Toronto, Ontario time, on the date specified for a proposed
Competitive Bid Loan; provided, however, that:

            (i) the failure by the applicable Canadian Borrower to accept or
      reject any Competitive Bid within the time period specified herein shall
      be deemed to be a rejection of such Competitive Bid,

            (ii) the aggregate amount of the Competitive Bids accepted by the
      applicable Canadian Borrower shall not exceed the principal amount
      specified in the Competitive Bid Request,

                                       13
<PAGE>
            (iii) the aggregate amount of all outstanding Canadian Loans and
      Canadian LC Obligations shall never exceed the Canadian Maximum Credit
      Amount,

            (iv) if the applicable Canadian Borrower shall accept a Competitive
      Bid or Competitive Bids made at a particular Competitive Bid Rate, but the
      amount of such Competitive Bid or Competitive Bids shall cause the total
      amount of Competitive Bids to be accepted by the applicable Canadian
      Borrower to exceed the amount specified in the Competitive Bid Request,
      then the applicable Canadian Borrower shall accept a portion of such
      Competitive Bid or Competitive Bids in an amount equal to the amount
      specified in the Competitive Bid Request less the amount of all other
      Competitive Bids accepted with respect to such Competitive Bid Request,
      which acceptance, in the case of multiple Competitive Bids at such
      Competitive Bid Rate, shall be made pro rata in accordance with the amount
      of each such Competitive Bid at such Competitive Bid Rate, and

            (v) no Competitive Bid shall be accepted for a Competitive Bid Loan
      unless such Competitive Bid Loan is in a minimum principal amount of C $
      5,000,000 or a higher integral multiple of C $1,000,000; provided,
      however, that if a Competitive Bid Loan must be in an amount less than C
      $5,000,000 because of the provisions of clause (iv) above, such
      Competitive Bid Loan may be for a minimum of C $1,000,000 or any higher
      integral multiple thereof, and in calculating the pro rata allocation of
      acceptances or portions of multiple bids at a particular Competitive Bid
      Rate pursuant to clause (iv), the amounts shall be rounded to integral
      multiples of C $1,000,000 in a manner which shall be in the sole and
      absolute discretion of the applicable Canadian Borrower.

      (e) Promptly on each date the applicable Canadian Borrower accepts a
Competitive Bid, Canadian Agent shall notify each Canadian Resident Lender
whether or not its Competitive Bid has been accepted (and if so, in what amount
and at what Competitive Bid Rate) by facsimile transmission sent by Canadian
Agent, and each successful bidder will thereupon become bound, subject to the
other applicable conditions hereof, to make the Competitive Bid Loan in respect
of which its Competitive Bid has been accepted. After completing the
notifications referred to in the immediately preceding sentence, Canadian Agent
shall notify each Canadian Resident Lender of the aggregate principal amount of
all Competitive Bids accepted. Each Canadian Resident Lender which is to make a
Competitive Bid Loan shall, before 11:00 a.m., Toronto, Ontario time, on the
borrowing date specified in the Competitive Bid Request applicable thereto, make
available to Canadian Agent in immediately available funds the amount of each
Competitive Bid Loan to be made by such Canadian Resident Lender, and Canadian
Agent shall promptly deposit such funds to an account designated by the
applicable Canadian Borrower. As soon as practicable thereafter, Canadian Agent
shall notify each Canadian Resident Lender of the aggregate amount of
Competitive Bid Loans advanced, the respective Competitive Bid Interest Periods
thereof and Competitive Bid Rate applicable thereto.

      (f) The obligation of the applicable Canadian Borrower to repay to each
Canadian Resident Lender the aggregate amount of all Competitive Bid Loans made
by such Canadian Resident Lender, together with interest accruing in connection
therewith, shall be evidenced by promissory notes (respectively, such Canadian
Resident Lender's "Competitive Bid Note") made

                                       14
<PAGE>
by the applicable Canadian Borrower payable to the order of such Canadian
Resident Lender in the form of Exhibit M, with appropriate insertions. The
amount of principal owing on any Canadian Resident Lender's Competitive Bid Note
at any given time shall be the aggregate amount of all Competitive Bid Loans
theretofore made by such Canadian Resident Lender thereunder minus all payments
of principal theretofore received by such Canadian Resident Lender thereon.
Interest on each Competitive Bid Note shall accrue and be due and payable as
provided herein and therein. The applicable Canadian Borrower shall repay on the
final day of the Competitive Bid Interest Period of each Competitive Bid Loan
(such date being that specified by the applicable Canadian Borrower for
repayment of such Competitive Bid Loan in the related Competitive Bid Request
and such date being no later than six months after the date of the Competitive
Bid Loan) the then unpaid principal amount of such Competitive Bid Loan. Subject
to Section 1.4(b) and the payment of amounts described in Section 3.6, the
applicable Canadian Borrower shall have the right to prepay any principal amount
of any Competitive Bid Loan.

      (g) No Competitive Bid Loan shall be made within five Business Days after
the date of any other Competitive Bid Loan, unless the applicable Canadian
Borrower and Canadian Agent shall mutually agree otherwise. If Canadian Agent
shall at any time elect to submit a Competitive Bid in its capacity as a
Canadian Resident Lender, it shall submit such bid directly to the applicable
Canadian Borrower requesting such Competitive Bid one quarter of an hour earlier
than the latest time at which the other Canadian Resident Lenders are required
to submit their bids to Canadian Agent.

      Section 1.10. Use of Proceeds. Canadian Borrowers shall use all Canadian
Advances and Canadian Swing Loans made under this Agreement to refinance
existing indebtedness (including any commercial paper issued by or for the
account of Canadian Borrowers), to finance capital expenditures, to refinance
Matured Canadian LC Obligations outstanding under this Agreement, and to provide
working capital for its operations and for other general business purposes.
Canadian Borrowers shall use all Letters of Credit issued under the Canadian
Agreement for its general corporate purposes. If any Canadian Advance or
Canadian Swing Loan is used for a purpose which is governed by Reg U, Canadian
Borrowers shall comply with Reg U in all respects. Each Canadian Borrower
represents and warrants that such Canadian Borrower is not engaged principally,
or as one of such Canadian Borrower's important activities, in the business of
extending credit to others for the purpose of purchasing or carrying Margin
Stock.

      Section 1.11. Refinancings of Canadian Swing Loans. Canadian Agent, at any
time in its sole and absolute discretion may (and on the Canadian Conversion
Date Canadian Agent shall), upon notice given to each Lender by not later than
11:30 a.m., Toronto, Ontario time, on any Business Day, request that each Lender
make a Canadian Prime Rate Loan (or another Type of Canadian Advance if
requested by the applicable Canadian Borrower in accordance with Section 1.2) in
an aggregate amount equal to its Percentage Share of the aggregate unpaid
principal amount of any outstanding Canadian Swing Loans for the purpose of
refinancing such Canadian Swing Loans (in this section called a "Refinancing
Advance"). In any event, not later than 11:30 a.m., Toronto, Ontario time, on
the penultimate Business Day of each calendar month, Canadian Agent will notify
each Lender of the

                                       15
<PAGE>
aggregate amount of Canadian Swing Loans which are then outstanding and the
amount of the Refinancing Advance required to be made by each Lender to
refinance such outstanding Canadian Swing Loans (the aggregate amount of such
Refinancing Advance to be made by each Lender shall equal such Lender's
Percentage Share of such outstanding Canadian Swing Loans). Upon the giving of
notices by Canadian Agent described above, each Lender shall promptly remit to
Canadian Agent such Refinancing Advance in the manner described above in Section
1.2, so long as (a) Canadian Agent believed in good faith that all conditions to
making the subject Canadian Swing Loan were satisfied at the time such Canadian
Swing Loan was made, or (b) if the conditions to such Canadian Swing Loan were
not satisfied, the satisfaction of such conditions have been waived in writing
by Canadian Required Lenders in accordance with the provisions of this Agreement
(collectively, the "Refinancing Conditions"). The proceeds of the Refinancing
Advances made pursuant to the preceding sentence shall be paid to Canadian Agent
(and not to either Canadian Borrower) and applied to the payment of principal of
the outstanding Canadian Swing Loans. If and to the extent any Lender shall not
so make its Refinancing Advance, such Lender and the applicable Canadian
Borrower severally agree to pay to Canadian Agent (for delivery to Canadian
Swing Lender) within three days after demand the amount of such Refinancing
Advance together with interest thereon, for each day from the date such
Refinancing Advance was required to be made until the date such amount is paid
to Canadian Agent, with interest at (1) the Canadian Prime Rate, if such Lender
is making such payment and (2) the interest rate applicable at the time to the
other new Refinancing Advances, if a Canadian Borrower is making such repayment;
provided that Canadian Agent gave notice of the terms of the refinancing to such
Lender in accordance with the terms of this Section 1.11. If neither such Lender
nor such Canadian Borrower pays to Canadian Agent (for delivery to Canadian
Swing Lender) such amount within such three-day period, Canadian Swing Lender
shall in addition to such amount be entitled to recover from such Lender and
from the applicable Canadian Borrower, on demand, interest on such Refinancing
Advance at the Default Rate applicable thereto, calculated from the date such
Refinancing Advance was required to be made. Each Lender's obligation to make
Refinancing Advances pursuant to this Section shall be absolute and
unconditional and shall not be affected by any circumstances, including, without
limitation, (1) any setoff, counterclaim, recoupment, defense or other right
which such Lender may have against Canadian Agent, Canadian Borrowers or anyone
else for any reason whatsoever; (2) the occurrence or continuance of an Event of
Default or Default; (3) any adverse change in the condition (financial or
otherwise) of either Canadian Borrower; (4) any breach of this Agreement by
either Canadian Borrower, Canadian Agent or any Lender, except with respect to
the Refinancing Conditions; or (5) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing; provided, that in no
event shall a Lender be obligated to make a Refinancing Advance pursuant to this
Section if, after giving effect thereto, the outstanding principal balance of
such Lender's Canadian Advances would exceed its Percentage Share of the
Canadian Maximum Credit Amount.

      Section 1.12. Re-allocation of Tranche B Maximum Credit Amount and
Canadian Maximum Credit Amount. Borrowers shall have the right (i) to
re-allocate up to US $100,000,000 of the unused Tranche B Maximum Credit Amount
to the Canadian Maximum Credit Amount (a "Tranche B Re-allocation") by reducing
the Tranche B Maximum

                                       16
<PAGE>
Credit Amount and increasing the Canadian Maximum Credit Amount by the same
amount and (ii) to re-allocate up to US $100,000,000 of the unused Canadian
Maximum Credit Amount to the Tranche B Maximum Credit Amount (a "Canadian
Re-allocation") by reducing the Canadian Maximum Credit Amount and increasing
the Tranche B Maximum Credit Amount by the same amount; provided that the
Tranche B Maximum Credit Amount shall never be greater than US $625,000,000, the
Canadian Maximum Credit Amount shall never be greater than US $375,000,000; the
aggregate amount of the Tranche B Maximum Credit Amount and the Canadian Maximum
Credit Amount shall never exceed US $800,000,000. A Re-allocation may be made
only on a Business Day which occurs during the Tranche B Revolving Period and
the Canadian Revolving Period, each Re-allocation shall remain in effect for at
least 90 days and thereafter until a subsequent Re-allocation is made in
accordance with the terms set forth in the Loan Documents, and no more than four
Re-allocations may be made during any Fiscal Year.

      (a To make any Tranche B Re-allocation, US Borrower must give to US Agent
written notice (or telephonic notice promptly confirmed in writing) of such
Tranche B Re-allocation. Each such notice must:

            (i) specify the amount by which the Tranche B Maximum Credit Amount
      will be reduced, which amount must be equal to US $25,000,000 or any
      higher integral multiple of US $1,000,000, and must also be equal to or
      less than the amount by which the Tranche B Maximum Credit Amount then in
      effect exceeds the Tranche B Facility Usage;

            (ii) specify that the Canadian Maximum Credit Amount will be
      increased by the same amount;

            (iii) specify the effective date of such Tranche B Re-allocation
      which must be at least 90 days after the effective date of the immediately
      preceding Re-allocation (whether a Tranche B Re-allocation or a Canadian
      Re-allocation); and

            (iv) be received by US Agent not later than 10:00 a.m., Dallas,
      Texas time, on or before the 10th Business Day preceding the day on which
      such Tranche B Re-allocation is to occur.

      (b To make any Canadian Re-allocation, Borrowers must give to US Agent
written notice (or telephonic notice promptly confirmed in writing) of such
Canadian Re-allocation. Each such notice must:

            (i) specify the amount by which the Canadian Maximum Credit Amount
      will be reduced, which amount must be equal to US $25,000,000 or any
      higher integral multiple of US $1,000,000, and must also be equal to or
      less than the amount by which the Canadian Maximum Credit Amount then in
      effect exceeds the Canadian Facility Usage;

            (ii) specify that the Tranche B Maximum Credit Amount will be
      increased by the same amount;

                                       17
<PAGE>
            (iii) specify the effective date of such Canadian Re-allocation
      which must be at least 90 days after the effective date of the immediately
      preceding Re-allocation (whether a Tranche B Re-allocation or a Canadian
      Re-allocation); and

            (iv) be received by US Agent not later than 10:00 a.m., Dallas,
      Texas time, on or before the 10th Business Day preceding the day on which
      such Canadian Re-allocation is to occur.

      Each written request or confirmation described in this section constitutes
a "Re-allocation Notice" and must be made in the form and substance of the
"Re-allocation Notice" attached hereto as Exhibit G, duly completed. Each such
telephonic request shall be deemed a representation, warranty, acknowledgment
and agreement by Borrowers as to the matters which are required to be set out in
such written confirmation. Upon receipt of any such Re-allocation Notice, US
Agent shall give Canadian Agent, each Tranche B Lender and each Canadian Lender
prompt notice of the terms thereof. Each Re-allocation Notice shall be
irrevocable and binding on Borrowers.

            ARTICLE II - Bankers' Acceptances and Letters of Credit

      Section 2.1. Creation of Bankers' Acceptances. Upon receipt of a Borrowing
Notice and subject to the provisions of this Agreement, each Canadian Resident
Lender shall accept, in accordance with its Percentage Share of the requested
Borrowing from time to time such Bankers' Acceptances as Canadian Borrowers
shall request provided that:

      (a Bankers' Acceptances shall be issued on a Business Day;

      (b each Bankers' Acceptance shall have a term of 30, 60, 90 or 180 days
(excluding days of grace), as selected by Canadian Borrowers in the relevant
Borrowing Notice provided that each Bankers' Acceptance shall mature on a
Business Day;

      (c the face amount of each Bankers' Acceptance shall be not less than
C$100,000 and in multiples of C$100,000 for any amounts in excess thereof; and

      (d each Bankers' Acceptance shall be in a form acceptable to the Canadian
Resident Lenders.

      Section 2.2. Terms of Acceptance by the Canadian Resident Lenders.

      (a Delivery and Payment. Subject to Sections 2.3 and 2.4 and only if a
valid appointment pursuant to Section 2.2(e) is not in place, Canadian Borrowers
shall pre-sign and deliver to each Canadian Resident Lender bankers' acceptance
drafts in sufficient quantity to meet

                                       18
<PAGE>
Canadian Borrowers' requirements for anticipated Borrowings by way of Bankers'
Acceptances. The applicable Canadian Borrower shall, at its option, provide for
payment to Canadian Agent for the benefit of Canadian Resident Lenders of each
Bankers' Acceptance on the date on which a Bankers' Acceptance matures, either
by payment of the full face amount thereof or through utilization of a
Conversion to another Type of Borrowing in accordance with this Agreement, or
through a combination thereof. Each Canadian Borrower waives presentment for
payment of Bankers' Acceptances by Canadian Resident Lenders and shall not claim
from Canadian Resident Lenders any days of grace for the payment at maturity of
Bankers' Acceptances. Any amount owing by Canadian Borrowers in respect of any
Bankers' Acceptance which is not paid in accordance with the foregoing, shall,
as and from the date on which such Bankers' Acceptance matures, be deemed to be
outstanding hereunder as a Canadian Prime Rate Loan.

      (b No Liability. Canadian Agent and Canadian Resident Lenders shall not be
liable for any damage, loss or improper use of any bankers' acceptance draft
endorsed in blank except for any loss arising by reason of Canadian Agent or a
Canadian Resident Lender failing to use the same standard of care in the custody
of such bankers' acceptance drafts as Canadian Agent or such Canadian Resident
Lender use in the custody of their own property of a similar nature.

      (c Bankers' Acceptances Purchased by Canadian Resident Lenders. Where the
applicable Canadian Borrower so elects in the Borrowing Notice or
Continuation/Conversion Notice, a Canadian Resident Lender shall purchase
Bankers' Acceptances accepted by it for an amount equal to the Discount
Proceeds.

      (d Marketing. Where the applicable Canadian Borrower so elects in the
Borrowing Notice or Continuation/Conversion Notice, it shall be responsible for,
and shall make its own arrangements with respect to, the marketing of Bankers'
Acceptances.

      (e Power of Attorney. To facilitate the procedures contemplated in this
Agreement, each Canadian Borrower appoints each Canadian Resident Lender from
time to time as the attorney-in-fact of such Canadian Borrower to execute,
endorse and deliver on behalf of such Canadian Borrower drafts or depository
bills in the form or forms prescribed by such Canadian Resident Lender for
Bankers' Acceptances denominated in Canadian Dollars. Each Bankers' Acceptance
executed and delivered by a Canadian Resident Lender on behalf of a Canadian
Borrower shall be as binding upon such Canadian Borrower as if it had been
executed and delivered by a duly authorized officer of such Canadian Borrower.
The foregoing appointment shall cease to be effective, in respect of any
Canadian Resident Lender regarding a Canadian Borrower, three Business Days
following receipt by such Canadian Resident Lender of a written notice from such
Canadian Borrower revoking such appointment (which notice shall be copied to the
Canadian Agent); provided that any such revocation shall not affect Bankers'
Acceptances previously executed and delivered by such Canadian Resident Lender
pursuant to such appointment.

      (f Non-resident Lenders Participation in Borrowing of Bankers' Acceptances
by Making Canadian Dollar Eurodollar Loans. As part of each Borrowing by way of
Bankers' Acceptances from Canadian Resident Lenders, each Non-resident Lender
shall, with respect to its

                                       19
<PAGE>
obligations to fund such Borrowing, make a Canadian Dollar Eurodollar Loan by
advancing Canadian Dollars in the amount of its Percentage Share of such
Borrowing having a Eurodollar Interest Period that is substantially the same as
the period to maturity of the Bankers' Acceptances that are accepted in such
Borrowing by Canadian Resident Lenders in order that all Borrowings other than
Competitive Bid Loans shall remain pro rata during the term of this Agreement.
Such Canadian Dollar Eurodollar Loan shall otherwise be made on the terms set
forth in Article I with respect to such Type of Loan.

      (g Canadian Dollars Unavailable to Non-resident Lenders. In the event that
(i) either Canadian Borrower has requested a Borrowing in Canadian Prime Rate
Loans or (ii) the Loans in any Borrowing are automatically converted to Canadian
Prime Rate Loans, and a Non-resident Lender is unable to obtain Canadian Dollars
with which to fund its Percentage Share of such Borrowing, such Non-resident
Lender may, with respect to its obligations to fund such Borrowing, make a
Canadian Base Rate Loan in an amount equal to the US Dollar Exchange Equivalent
of its Percentage Share of such Borrowing.

      (h Pro-Rata Treatment of Canadian Advances.

            (i) Each Canadian Advance shall be made available by each Lender and
      all repayments and reductions in respect thereof shall be made and applied
      in a manner so that the Canadian Advances outstanding hereunder to each
      Lender will, to the extent possible (but in any event, to the extent
      necessary to comply with Section 1.4(b)(iii)), thereafter be pro rata in
      accordance with such Lender's Percentage Share. The Canadian Agent is
      authorized by each Canadian Borrower and each Lender to determine, in its
      sole and unfettered discretion, the portion of each Canadian Advance and
      each Type of Canadian Advance to be made available by each Lender and the
      application of repayments and reductions of Canadian Advances to give
      effect to the provisions of this Section, provided that no Lender shall,
      as a result of any such determination, have a Percentage Share of the
      Canadian Advances which is in excess of its Percentage Share of the
      Canadian Maximum Credit Amount.

            (ii) In the event it is not practicable to allocate Bankers'
      Acceptances to each Lender such that the aggregate amount of Bankers'
      Acceptances required to be purchased by such Lender hereunder is in a
      whole multiple of C $100,000, the Canadian Agent is authorized by each
      Canadian Borrower and each Lender to make such allocation as the Canadian
      Agent determines in its sole and unfettered discretion may be equitable in
      the circumstances and, if the aggregate amount of such Bankers'
      Acceptances is not a whole multiple of C $100,000, then the Canadian Agent
      may allocate (on a basis considered by it to be equitable) the excess of
      such Canadian Advance over the next lowest whole multiple of C $100,000 to
      one Lender, which shall purchase a Bankers' Acceptance with a face amount
      equal to the excess and having the same term as the corresponding Bankers'
      Acceptances. In no event shall the portion of the outstanding Borrowings
      by way of Bankers' Acceptances of a Lender exceed such Lenders' Percentage
      Share of the Aggregate Borrowings by way of Bankers' Acceptances by more
      than C $100,000 as a result of such exercise of discretion by the Canadian
      Agent.

                                       20
<PAGE>
            (iii) If during the term of any Bankers' Acceptance accepted by a
      Lender hereunder the Applicable Margin changes or an Event of Default
      occurs and is continuing, the fee paid to such Lender by the applicable
      Borrower pursuant to Section 1.5(d) (in this paragraph called the "Initial
      Fee") with respect to such Bankers' Acceptance shall be recalculated based
      upon such change in the Applicable Margin or the existence of such Event
      of Default for the number of days during the term of such Bankers'
      Acceptance that such change is applicable or such Event of Default exists.
      If such recalculated amount is in excess of the Initial Fee then such
      Canadian Borrower shall pay to such Lender the amount of such excess, and
      if such recalculated amount is less than the Initial Fee, then the amount
      of such reduction shall be credited to other amounts payable by such
      Canadian Borrower to such Lender.

      Section 2.3. General Procedures for Bankers' Acceptances.

      (a Notice. Either Canadian Borrower may in the Borrowing Notice or in a
Continuation/Conversion Notice request a Borrowing by way of Bankers'
Acceptances and, if the applicable Canadian Borrower is responsible for
marketing of such Bankers' Acceptances under Section 2.2(d), by subsequent
notice to Canadian Agent provide Canadian Agent, which shall in turn notify each
Canadian Resident Lender, with information as to the discount proceeds payable
by the purchasers of the Bankers' Acceptances and the party to whom delivery of
the Bankers' Acceptances by each Canadian Resident Lender is to be made against
delivery to each Canadian Resident Lender of the applicable discount proceeds,
but if it does not do so, the applicable Canadian Borrower shall initiate a
telephone call to Canadian Agent by 10:00 a.m. Toronto, Ontario time on the date
of advance, or the date of the Continuation or Conversion, as applicable, and
provide such information to Canadian Agent. Such discount proceeds less the fee
calculated in accordance with Section 1.5(d) shall promptly be delivered to the
Canadian Agent. Any such telephone advice shall be subject to Section 1.2 and
shall be confirmed by a written notice of the applicable Canadian Borrower to
Canadian Agent prior to 2:00 p.m. Toronto, Ontario time on the same day.

      (b Continuations. In the case of a Continuation of maturing Bankers'
Acceptances, issued by a Canadian Resident Lender, such Canadian Resident
Lender, in order to satisfy the continuing liability of the applicable Canadian
Borrower to the Canadian Resident Lender for the face amount of the maturing
Bankers' Acceptances issued by such Canadian Borrower, shall retain for its own
account the Net Proceeds of each new Bankers' Acceptance issued by it in
connection with such Continuation; and the applicable Canadian Borrower shall,
on the maturity date of the maturing Bankers' Acceptances issued by such
Canadian Borrower, pay to Canadian Agent for the benefit of Canadian Resident
Lenders an amount equal to the difference between the face amount of the
maturing Bankers' Acceptances and the aggregate Net Proceeds of the new Bankers'
Acceptances.

      (c Conversion from Canadian Prime Rate Loans and Canadian Dollar
Eurodollar Loans. In the case of a Conversion from a Borrowing of Canadian Prime
Rate Loans or Canadian

                                       21
<PAGE>
Dollar Eurodollar Loans into a Borrowing by way of Bankers' Acceptances to be
accepted by a Canadian Resident Lender pursuant to Sections 2.1, 2.2 and 2.3,
such Canadian Resident Lender, in order to satisfy the continuing liability of
the applicable Canadian Borrower to it for the principal amount of the Canadian
Prime Rate Loans or Canadian Dollar Eurodollar Loans owing by such Canadian
Borrower being converted, shall retain for its own account the Discount Proceeds
of each new Bankers' Acceptance issued by it in connection with such Conversion;
and the applicable Canadian Borrower shall, on the date of issuance of the
Bankers' Acceptances, pay to Canadian Agent for the benefit of Canadian Resident
Lenders an amount equal to the difference between the aggregate principal amount
of the Canadian Prime Rate Loans or Canadian Dollar Eurodollar Loans owing by
such Canadian Borrower being converted owing to the Canadian Resident Lenders
and the aggregate Discount Proceeds of such Bankers' Acceptances.

      (d Conversions to Canadian Loans in Canadian Dollars. In the case of a
Conversion of a Borrowing by way of Bankers' Acceptances into Canadian Loans,
each Canadian Resident Lender, in order to satisfy the liability of the
applicable Canadian Borrower to it for the face amount of the maturing Bankers'
Acceptances, shall record the obligation of the applicable Canadian Borrower to
it as a Canadian Prime Rate Loan, unless the applicable Canadian Borrower
provides for payment to Canadian Agent for the benefit of Canadian Resident
Lenders of the face amount of the maturing Bankers' Acceptance in some other
manner acceptable to Canadian Resident Lenders, including Conversion to another
Type of Canadian Loan pursuant to a Continuation/Conversion Notice.

      (e Conversion from or to Canadian Loans in U.S. Dollars. In the case of a
conversion of Bankers' Acceptances from or to a Canadian Base Rate Loans or US
Dollar Eurodollar Loans, the parties to which this Section applies shall follow
the notice procedures set out in Section 1.3 and the funding procedures set out
in Section 2.3 (c) and (d) without netting of funds.

      (f Authorization. Canadian Borrowers hereby authorize each Canadian
Resident Lender to complete, stamp, hold, sell, rediscount or otherwise dispose
of all Bankers' Acceptances accepted by it pursuant to this Section in
accordance with the instructions provided by Canadian Borrowers pursuant to
Section 1.3, as applicable.

      (g Depository Notes. The parties agree that in the administering of
Bankers' Acceptances, each Lender may avail itself of the debt clearing services
offered by a clearing house for depository notes pursuant to the Depository
Bills and Notes Act (Canada) and that the procedures set forth in Article II be
deemed amended to the extent necessary to comply with the requirements of such
debt clearing services.

      Section 2.4. Execution of Bankers' Acceptances. The signatures of any
authorized signatory on Bankers' Acceptances may, at the option of Canadian
Borrowers, be reproduced in facsimile and such Bankers' Acceptances bearing such
facsimile signatures shall be binding on Canadian Borrowers as if they had been
manually signed by such authorized signatory. Notwithstanding that any person
whose signature appears on any Bankers' Acceptance as a signatory may no longer
be an authorized signatory of Canadian

                                       22
<PAGE>
Borrowers at the date of issuance of a Bankers' Acceptance, and notwithstanding
that the signature affixed may be a reproduction only, 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 as if such signature had been
manually applied, and any such Bankers' Acceptance so signed shall be binding on
Canadian Borrowers.

      Section 2.5. Escrowed Funds. Upon the occurrence of an Event of Default
and an acceleration of the Canadian Obligations under Section 8.1 or upon a
prepayment permitted under Section 1.4, the applicable Canadian Borrower shall
forthwith pay to Canadian Agent for deposit into an escrow account maintained by
and in the name of Canadian Agent for the benefit of Canadian Resident Lenders
in accordance with their Percentage Shares an amount equal to the Canadian
Resident Lenders' maximum potential liability (as determined by Canadian Agent)
under then outstanding Bankers' Acceptances for the applicable Canadian Borrower
(the "Escrow Funds"). The Escrow Funds shall be held by Canadian Agent for
set-off against future Canadian Obligations of the applicable Canadian Borrower
and pending such application shall bear interest at the rate declared by
Canadian Agent from time to time as that payable by it in respect of deposits
for such amount and for such period relative to the maturity date of the
Bankers' Acceptances, as applicable. If such Event of Default is either waived
or cured in compliance with the terms of this Agreement, then the Escrow Funds,
together with any accrued interest to the date of release, shall be forthwith
released to the applicable Canadian Borrower.

      Section 2.6. Letters of Credit. Subject to the terms and conditions
hereof, either Canadian Borrower may during the Canadian Revolving Period
request Canadian LC Issuer to issue one or more Letters of Credit denominated in
either Canadian Dollars or US Dollars, provided that, after taking such Letter
of Credit into account:

      (a the Canadian Facility Usage does not exceed the Canadian Maximum Credit
Amount at such time;

      (b the aggregate amount of Canadian LC Obligations arising from Letters of
Credit issued under this Agreement at such time does not exceed the Canadian LC
Sublimit;

      (c the expiration date of such Letter of Credit is no more than one year
after the date of issuance thereof;

      (d such Letter of Credit is to be used for general corporate purposes of
such Canadian Borrower or one or more of its Subsidiaries;

      (e such Letter of Credit is not directly or indirectly used to assure
payment of or otherwise support any Indebtedness of any Person other than
Indebtedness of any Restricted Person permitted by this Agreement;

      (f the issuance of such Letter of Credit will be in compliance with all
applicable governmental restrictions, policies, and guidelines and will not
subject Canadian LC Issuer to any cost which is not reimbursable under Article
III;

                                       23
<PAGE>
      (g the form and terms of such Letter of Credit are acceptable to Canadian
LC Issuer in its reasonable discretion; and

      (h all other conditions in this Agreement to the issuance of such Letter
of Credit have been satisfied.

      Subject to the terms and conditions set forth herein, Canadian LC Issuer
will, in reliance upon the agreements of the other Lenders set forth in Section
2.8(a), honor any such request if the foregoing conditions (a) through (h) (in
this Section 2.6 called the "LC Conditions") have been met as of the date of
issuance of such Letter of Credit. Canadian LC Issuer may choose to honor any
such request for any other Letter of Credit but has no obligation to do so and
may refuse to issue any other requested Letter of Credit for any reason which
Canadian LC Issuer in its sole discretion deems relevant.

      Section 2.7. Requesting Letters of Credit. The applicable Canadian
Borrower must make written application for any Letter of Credit at least three
Business Days before the date on which the applicable Canadian Borrower desires
for Canadian LC Issuer to issue such Letter of Credit. By making any such
written application the applicable Canadian Borrower shall be deemed to have
represented and warranted that the LC Conditions described in Section 2.6 will
be met as of the date of issuance of such Letter of Credit. Each such written
application for a Letter of Credit must be made in writing on Canadian LC
Issuer's standard form of Letter of Credit Application, the terms and provisions
of which are hereby incorporated herein by reference (or in such other form as
may mutually be agreed upon by Canadian LC Issuer and the applicable Canadian
Borrower). Three Business Days after the LC Conditions for a Letter of Credit
have been met as described in Section 2.6 (or if Canadian LC Issuer otherwise
desires to issue such Letter of Credit), Canadian LC Issuer will issue such
Letter of Credit at Canadian LC Issuer's office in Toronto, Ontario. If any
provisions of any LC Application conflict with any provisions of this Agreement,
the provisions of this Agreement shall govern and control.

      Section 2.8. Reimbursement and Participations.

      (a Reimbursement by Canadian Borrowers.

            (i) Prior to Canadian Conversion Date. Each Matured Canadian LC
      Obligation arising prior to the Canadian Conversion Date from a Letter of
      Credit issued under the Canadian Agreement shall constitute Canadian Prime
      Rate Loans made by Canadian LC Issuer to the applicable Canadian Borrower
      even if any condition precedent to the making of such a Loan shall not
      have been satisfied. Each Lender shall (in all circumstances and without
      set-off or counterclaim) purchase from Canadian LC Issuer its Percentage
      Share of such Canadian Prime Rate Loans and pay to Canadian LC Issuer on
      demand on the date on which such Matured LC Obligation arises, in
      immediately available funds at Canadian LC Issuer's address for notices
      hereunder, such Lender's Percentage Share of such Matured Canadian LC
      Obligation. Each Lender's obligation to pay

                                       24
<PAGE>
      Canadian LC Issuer pursuant to the terms of this subsection is irrevocable
      and unconditional. If any amount required to be paid by any Lender to
      Canadian LC Issuer pursuant to this subsection is paid by such Lender to
      Canadian LC Issuer within three Business Days after the date such payment
      is due, Canadian LC Issuer shall in addition to such amount be entitled to
      recover from such Lender, on demand, interest thereon calculated from such
      due date at the Canadian Prime Rate. If any amount required to be paid by
      any Lender to Canadian LC Issuer pursuant to this subsection is not paid
      by such Lender to Canadian LC Issuer within three Business Days after the
      date such payment is due, Canadian LC Issuer shall in addition to such
      amount be entitled to recover from such Lender, on demand, interest
      thereon calculated from such due date at the applicable Default Rate.

            (ii) From and After Canadian Conversion Date. Each Matured Canadian
      LC Obligation arising from and after the Canadian Conversion Date from an
      Overterm Canadian LC issued under the Canadian Agreement shall constitute
      Canadian Prime Rate Loans made by Canadian LC Issuer to the applicable
      Canadian Borrower and no conditions precedent to the making of such a Loan
      shall be required (herein called "Overterm Canadian Loans"). Each Lender
      shall (in all circumstances and without set-off or counterclaim) purchase
      from Canadian LC Issuer its Percentage Share of such Canadian Prime Rate
      Loans and pay to Canadian LC Issuer on demand on the date on which such
      Matured LC Obligation arises, in immediately available funds at Canadian
      LC Issuer's address for notices hereunder, such Lender's Percentage Share
      of such Matured Canadian LC Obligation. Each Lender's obligation to pay
      Canadian LC Issuer pursuant to the terms of this subsection is irrevocable
      and unconditional. If any amount required to be paid by any Lender to
      Canadian LC Issuer pursuant to this subsection is paid by such Lender to
      Canadian LC Issuer within three Business Days after the date such payment
      is due, Canadian LC Issuer shall in addition to such amount be entitled to
      recover from such Lender, on demand, interest thereon calculated from such
      due date at the Canadian Prime Rate. If any amount required to be paid by
      any Lender to Canadian LC Issuer pursuant to this subsection is not paid
      by such Lender to Canadian LC Issuer within three Business Days after the
      date such payment is due, Canadian LC Issuer shall in addition to such
      amount be entitled to recover from such Lender and from the applicable
      Canadian Borrower, on demand, interest thereon calculated from such due
      date at the applicable Default Rate.

      (b Calculations. A written advice setting forth in reasonable detail the
amounts owing under this section, submitted by Canadian LC Issuer to Canadian
Borrowers or any Lender from time to time, shall be conclusive, absent manifest
error, as to the amounts thereof.

      Section 2.9. Letter of Credit Fees. In consideration of Canadian LC
Issuer's issuance of any Letter of Credit, the applicable Canadian Borrower
agrees to pay (a) to Canadian LC Issuer for its own account, a letter of credit
fronting fee at a rate equal to 12.5 Basis Points per annum multiplied by the
face amount of such Letter of Credit, payable on the date of issuance, and (b)
to Canadian Agent, for the account of all Lenders in accordance with their
respective Percentage Shares, a letter of credit issuance fee calculated by

                                       25
<PAGE>
applying the Applicable Margin to the face amount of all Letters of Credit
outstanding on each day, payable in arrears on the last day of each Fiscal
Quarter. In addition, the applicable Canadian Borrower will pay to LC Issuer its
standard drawing and other processing fees upon any drawing under a Letter of
Credit.

      Section 2.10. No Duty to Inquire.

      (a Drafts and Demands. Canadian LC Issuer is authorized and instructed to
accept and pay drafts and demands for payment under any Letter of Credit without
requiring, and without responsibility for, any determination as to the existence
of any event giving rise to said draft, either at the time of acceptance or
payment or thereafter. Canadian LC Issuer is under no duty to determine the
proper identity of anyone presenting such a draft or making such a demand
(whether by tested telex or otherwise) as the officer, representative or agent
of any beneficiary under any Letter of Credit, and payment by Canadian LC Issuer
to any such beneficiary when requested by any such purported officer,
representative or agent is hereby authorized and approved. Canadian Borrowers
release each Lender Party from, and agree to hold each Lender Party harmless and
indemnified against, any liability or claim in connection with or arising out of
the subject matter of this section, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT
ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR
IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY,
provided only that no Lender Party shall be entitled to indemnification for that
portion, if any, of any liability or claim which is proximately caused by its
own individual gross negligence or willful misconduct, as determined in a final
judgment.

      (b Extension of Maturity. If the maturity of any Letter of Credit is
extended by its terms or by Law or governmental action, if any extension of the
maturity or time for presentation of drafts or any other modification of the
terms of any Letter of Credit is made at the request of any Restricted Person,
or if the amount of any Letter of Credit is increased at the request of any
Restricted Person, this Agreement shall be binding upon all Restricted Persons
with respect to such Letter of Credit as so extended, increased or otherwise
modified, with respect to drafts and property covered thereby, and with respect
to any action taken by Canadian LC Issuer, Canadian LC Issuer's correspondents,
or any Lender Party in accordance with such extension, increase or other
modification.

      (c Transferees of Letters of Credit. If any Letter of Credit provides that
it is transferable, Canadian LC Issuer shall have no duty to determine the
proper identity of anyone appearing as transferee of such Letter of Credit, nor
shall Canadian LC Issuer be charged with responsibility of any nature or
character for the validity or correctness of any transfer or successive
transfers, and payment by Canadian LC Issuer to any purported transferee or
transferees as determined by Canadian LC Issuer is hereby authorized and
approved, and Canadian Borrowers release each Lender Party from, and agree to
hold each Lender Party harmless and indemnified against, any liability or claim
in connection with or arising out of the foregoing, WHICH INDEMNITY SHALL APPLY
WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT
CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY

                                       26
<PAGE>
ANY LENDER PARTY, provided only that no Lender Party shall be entitled to
indemnification for that portion, if any, of any liability or claim which is
proximately caused by its own individual gross negligence or willful misconduct,
as determined in a final judgment.

      Section 2.11. LC Collateral.

      (a Canadian LC Obligations in Excess of Canadian Maximum Credit Amount.
If, after the making of all mandatory prepayments required under Section 1.4(c),
the outstanding Canadian LC Obligations will exceed Canadian Maximum Credit
Amount, then in addition to prepayment of the entire principal balance of the
Canadian Loans, the applicable Canadian Borrower will immediately pay to
Canadian LC Issuer an amount equal to such excess. Canadian LC Issuer will hold
such amount to apply against the remaining Canadian LC Obligations outstanding
under the Canadian Agreement (all such amounts held for Canadian LC Obligations
under this Section 2.11(a) or Section 2.11(b) being herein collectively called
"LC Collateral") and the other Canadian Obligations, and such collateral may be
applied from time to time to any Matured Canadian LC Obligations or other
Canadian Obligations which are due and payable. Neither this subsection nor the
following subsection shall, however, limit or impair any rights which Canadian
LC Issuer may have under any other document or agreement relating to any Letter
of Credit, LC Collateral or Canadian LC Obligation, including any LC
Application, or any rights which any Lender Party may have to otherwise apply
any payments by Canadian Borrowers and any LC Collateral under Section 3.1.

      (b Acceleration of Canadian LC Obligations. If the Canadian Obligations or
any part thereof become immediately due and payable pursuant to Section 8.1
then, unless Canadian Required Lenders otherwise specifically elect to the
contrary (which election may thereafter be retracted by Canadian Required
Lenders at any time), all Canadian LC Obligations shall become immediately due
and payable without regard to whether or not actual drawings or payments on the
Letters of Credit have occurred, and the applicable Canadian Borrower in respect
of such Canadian LC Obligations shall be obligated to pay to Canadian LC Issuer
immediately an amount equal to the aggregate Canadian LC Obligations which are
then outstanding.

      (c Investment of LC Collateral. Pending application thereof, all LC
Collateral shall be invested by Canadian LC Issuer in such Investments as
Canadian LC Issuer may choose in its sole discretion. All interest on (and other
proceeds of) such Investments shall be reinvested or applied to Matured Canadian
LC Obligations or other Canadian Obligations of the applicable Canadian Borrower
which are due and payable. When all Canadian Obligations have been satisfied in
full, including all Canadian LC Obligations, all Letters of Credit have expired
or been terminated, and all of the applicable Canadian Borrower's reimbursement
obligations in connection therewith have been satisfied in full, Canadian LC
Issuer shall release any remaining LC Collateral. Each Canadian Borrower hereby
assigns and grants to Canadian LC Issuer a continuing security interest in all
LC Collateral paid by it to Canadian LC Issuer, all Investments purchased with
such LC Collateral, and all proceeds thereof to secure its Matured Canadian LC
Obligations and the other Canadian Obligations owing by it under the Canadian
Loan Documents. Each Canadian Borrower further agrees that Canadian LC Issuer
shall have all of the rights and

                                       27
<PAGE>
remedies of a secured party under the Personal Property Security Act (Alberta)
with respect to such security interest and that an Event of Default under this
Agreement shall constitute a default for purposes of such security interest.
When either Canadian Borrower is required to provide LC Collateral for any
reason and fails to do so on the day when required, Canadian LC Issuer may
without notice to Canadian Borrowers or any other Restricted Person provide such
LC Collateral (whether by transfers from other accounts maintained with Canadian
LC Issuer, or otherwise) using any available funds of the applicable Canadian
Borrower or any other Person also liable to make such payments.

                       ARTICLE III - Payments to Lenders

      Section 3.1. General Procedures. Each Canadian Borrower will make each
payment which it owes under the Canadian Loan Documents to Canadian Agent in
Toronto, Canada, if such payment is being made in Canadian Dollars, or to the US
Account, if such payment is being made in US Dollars, in each case for the
account of the Lender Party to whom such payment is owed, without set-off,
deduction or counterclaim, and in immediately available funds, provided that any
such payment may be made net of any deduction or withholding for or on account
of any withholding tax which such Canadian Borrower is required at Law to
withhold or deduct except as otherwise provided in Sections 3.2(d) and 3.2(e).
Each such payment must be received by Canadian Agent not later than 11:00 a.m.,
Toronto, Ontario time, on the date such payment becomes due and payable. Any
payment received by Canadian Agent after such time will be deemed to have been
made on the next following Business Day. Should any such payment become due and
payable on a day other than a Business Day, the maturity of such payment shall
be extended to the next succeeding Business Day, and, in the case of a payment
of principal or past due interest, interest shall accrue and be payable thereon
for the period of such extension as provided in the Canadian Loan Document under
which such payment is due. Each payment under a Canadian Loan Document shall be
due and payable at the place provided therein and, if no specific place of
payment is provided, shall be due and payable at the place of payment of
Canadian Agent's Canadian Note. When Canadian Agent collects or receives money
on account of the Canadian Obligations of a Canadian Borrower, Canadian Agent
shall distribute all money so collected or received by 2:00 p.m. Toronto,
Ontario time on the Business Day received, if received by 11:00 a.m. Toronto,
Ontario time, otherwise on the day of deemed receipt, and each Lender Party
shall apply all such money so distributed, as follows:

      (a first, for the payment of all Canadian Obligations of such Canadian
Borrower which are then due (and if such money is insufficient to pay all such
Canadian Obligations, first to any reimbursements due Canadian Agent under
Section 6.9 or 10.4, then to any reimbursement due any other Lender Party under
Section 10.4, and then to the partial payment of all other Canadian Obligations
of such Canadian Borrower then due in proportion to the amounts thereof, or as
Lender Parties shall otherwise agree);

      (b then for the prepayment of amounts owing by such Canadian Borrower
under the Canadian Loan Documents (other than principal on the Canadian Notes)
if so specified by such Canadian Borrower;

                                       28
<PAGE>
      (c then for the prepayment of principal on the Canadian Notes of such
Canadian Borrower that are not Competitive Bid Notes, together with accrued and
unpaid interest on the principal so prepaid; and

      (d last, for the payment or prepayment of any other Canadian Obligations
of such Canadian Borrower.

      All payments applied to principal or interest on any Canadian Note shall
be applied first to any interest then due and payable, then to principal then
due and payable, and last to any prepayment of principal and interest in
compliance with Sections 1.4 and 2.8. All distributions of amounts described in
any of subsections (b), (c) or (d) above shall be made by Canadian Agent pro
rata to each Lender Party then owed Canadian Obligations described in such
subsection in proportion to all amounts owed to all Lender Parties which are
described in such subsection; provided that if any Lender then owes payments to
Canadian LC Issuer for the purchase of a participation under Section 2.8(a) or
to Canadian Agent under Section 9.8, any amounts otherwise distributable under
this section to such Lender shall be deemed to belong to Canadian LC Issuer, or
Canadian Agent, respectively, to the extent of such unpaid payments, and
Canadian Agent shall apply such amounts to make such unpaid payments rather than
distribute such amounts to such Lender.

      Section 3.2. Change in Law; Gross Up; Increased Cost and Reduced Return.

      (a If, after the date hereof, the adoption of any applicable Law, rule, or
regulation, or any change in any applicable Law, rule, or regulation, or any
change in the interpretation or administration thereof by any Governmental
Authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender Party (or its Applicable
Lending Office) with any request or directive (whether or not having the force
of Law) of any such Governmental Authority, central bank, or comparable agency
(the occurrence of any of the foregoing events being herein referred to as a
"Change in Law"):

            (i) shall subject such Lender Party (or its Applicable Lending
      Office) to any tax, duty, deduction or any other charge (other than with
      respect to Withholding Tax as defined in Section 3.2(d)) with respect to
      any Eurodollar Loans, Bankers' Acceptances or Competitive Bid Loans, or
      its obligation to make Eurodollar Loans, accept Bankers' Acceptances or
      issue Letters of Credit, or change the basis of taxation of any amounts
      payable to such Lender Party (or its Applicable Lending Office) under this
      Agreement or its Canadian Note in respect of any Eurodollar Loans,
      Bankers' Acceptances or Competitive Bid Loans other than taxes (including
      franchise taxes) imposed on the overall net income or capital of such
      Lender Party by the jurisdiction under the Laws of which such Lender Party
      (or its Applicable Lending Office) is organized or is a resident for tax
      purposes or any political subdivision thereof;

            (ii) shall impose, modify, or deem applicable any reserve, special
      deposit, assessment, or similar requirement (other than the Reserve
      Requirement utilized in the

                                       29
<PAGE>
      determination of the Adjusted US Dollar Eurodollar Rate and Adjusted
      Canadian Dollar Eurodollar Rate) relating to any extensions of credit or
      other assets of, or any deposits with or other liabilities or commitments
      of, such Lender Party (or its Applicable Lending Office), including the
      commitment of such Lender Party hereunder; or

            (iii) shall impose on such Lender Party (or its Applicable Lending
      Office) or the London interbank market any other condition affecting this
      Agreement or its Canadian Notes or any of such extensions of credit or
      liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender
Party (or its Applicable Lending Office) of making, converting into, continuing,
or maintaining any Eurodollar Loans, Bankers' Acceptances or Competitive Bid
Loans or to reduce any sum received or receivable by such Lender Party (or its
Applicable Lending Office) under this Agreement or its Canadian Notes with
respect to any Eurodollar Loans, Bankers' Acceptances or Competitive Bid Loans,
then the applicable Canadian Borrower shall pay to such Lender Party on demand
such amount or amounts as will compensate such Lender Party for such increased
cost or reduction. If any Lender Party requests compensation by Canadian
Borrowers under this Section 3.2(a), Canadian Borrowers may, by notice to such
Lender Party (with a copy to Canadian Agent), suspend the obligation of such
Lender Party to make or continue Canadian Advances of the Type with respect to
which such compensation is requested, or to convert Canadian Advances of any
other Type into Canadian Advances of such Type, until the event or condition
giving rise to such request ceases to be in effect (in which case the provisions
of Section 3.5 shall be applicable); provided that such suspension shall not
affect the right of such Lender Party to receive the compensation so requested.

      (b If, after the date hereof, Canadian LC Issuer or any Lender Party shall
have determined that the adoption of any applicable Law, rule, or regulation
regarding capital adequacy or any change therein or in the interpretation or
administration thereof by any Governmental Authority, central bank, or
comparable agency charged with the interpretation or administration thereof, or
any request or directive regarding capital adequacy (whether or not having the
force of Law) of any such Governmental Authority, central bank, or comparable
agency, has or would have the effect of reducing the rate of return on the
capital of such Lender Party or any corporation controlling such Lender Party as
a consequence of the obligations of such Lender Party hereunder to a level below
that which such Lender Party or such corporation could have achieved but for
such adoption, change, request, or directive (taking into consideration its
policies with respect to capital adequacy), then from time to time upon demand
the applicable Canadian Borrower shall pay to such Lender Party such additional
amount or amounts as will compensate such Lender Party for such reduction, but
only to the extent that such Lender Party has not been compensated therefor by
any increase in the Adjusted US Dollar Eurodollar Rate or the Adjusted Canadian
Dollar Eurodollar Rate; provided that if such Lender Party fails to give notice
to Canadian Borrowers of any additional costs within ninety (90) days after it
has actual knowledge thereof, such Lender Party shall not be entitled to
compensation for such additional costs incurred more than ninety (90) days prior
to the date on which notice is given by such Lender Party.

                                       30
<PAGE>
      (c Each Lender Party shall promptly notify Canadian Borrowers and Canadian
Agent of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Lender Party to compensation pursuant to this Section
and will designate a different Applicable Lending Office if such designation
will avoid the need for, or reduce the amount of, such compensation and will
not, in the judgment of such Lender Party, be otherwise disadvantageous to it.
Any Lender Party claiming compensation under this Section shall furnish to
Canadian Borrowers and Canadian Agent a statement setting forth the additional
amount or amounts to be paid to it hereunder which shall be conclusive in the
absence of manifest error. In determining such amount, such Lender Party shall
act in good faith and may use any reasonable averaging and attribution methods.

      (d If by reason of a Change in Law, either Canadian Borrower shall be
required to withhold and remit withholding taxes in respect of any principal,
interest, or other amount paid or payable by it to or for the account of any
Lender Party hereunder or under any other Canadian Loan Document (a "Withholding
Tax"), (i) the sum payable by the applicable Canadian Borrower shall be
increased as necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 3.2) such
Lender Party receives an amount equal to the sum it would have received had no
such deductions been made, (ii) the applicable Canadian Borrower shall make such
deductions, and (iii) the applicable Canadian Borrower shall pay the full amount
deducted to the relevant taxation authority or other authority in accordance
with applicable Law.

      (e If any Overterm Canadian LC is issued for the account of either
Canadian Borrower and such Canadian Borrower is required by applicable Law to
withhold and remit Withholding Taxes in respect of:

            (i) such Overterm Canadian LC,

            (ii) any Matured Canadian LC Obligation and any Canadian Loan, the
      proceeds of which (including indirectly by way of Conversion or
      Continuation) were applied to any such Matured Canadian LC Obligation,
      arising from such Overterm Canadian LC, or

            (iii) any other Canadian Loan where such Withholding Taxes would not
      have arisen if the terms of this Agreement did not permit the issuance of
      Overterm Canadian LCs and Overterm Canadian Loans,

      then:

            (x) the sum payable by the applicable Canadian Borrower shall be
      increased as necessary so that after making all required deductions
      (including deductions applicable to additional sums payable under this
      Section 3.2) each Lender Party receives an amount equal to the sum it
      would have received had no such deductions been made,

      (y) the applicable Canadian Borrower shall make such deductions, and

                                       31
<PAGE>
            (z) the applicable Canadian Borrower shall pay the full amount
      deducted to the relevant taxation authority or other authority in
      accordance with applicable Law.

      (f Except as provided in paragraphs (d) and (e) of this Section 3.2, no
Canadian Borrower shall be required to compensate any Lender Party for any
Withholding Taxes which such Canadian Borrower is required to withhold and remit
in respect of any principal, interest, or other amount paid or payable by it to
or for the account of any Lender Party hereunder or under any other Canadian
Loan Document.

      Section 3.3. Limitation on Types of Canadian Loans. If on or prior to the
first day of any Eurodollar Interest Period for any Eurodollar Loan:

      (a Canadian Agent determines (which determination shall be conclusive)
that by reason of circumstances affecting the relevant market, adequate and
reasonable means do not exist for ascertaining the US Dollar Eurodollar Rate or
the Canadian Dollar Eurodollar Rate, as applicable, for such Eurodollar Interest
Period; or

      (b the Canadian Required Lenders determine (which determination shall be
conclusive) and notify Canadian Agent that the Adjusted US Dollar Eurodollar
Rate or the Adjusted Canadian Dollar Eurodollar Rate, as applicable, will not
adequately and fairly reflect the cost to the Lenders of funding Eurodollar
Loans or for such Eurodollar Interest Period;

then Canadian Agent shall give Canadian Borrowers prompt notice thereof
specifying the relevant amounts or periods, and so long as such condition
remains in effect, the Lender Parties shall be under no obligation to make
additional Canadian Loans, continue Eurodollar Loans or convert Canadian Base
Rate Loans or Canadian Dollar Prime Rate Loans into Eurodollar Loans, and the
applicable Canadian Borrower shall, on the last day(s) of the then current
Eurodollar Interest Period(s) for the outstanding Eurodollar Loans, either
prepay such Canadian Loans or convert such Canadian Loans into Canadian Base
Rate Loans, Canadian Prime Rate Loans, or Bankers' Acceptances in accordance
with the terms of this Agreement.

      Section 3.4. Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender Party or its
Applicable Lending Office to make, maintain, or fund Eurodollar Loans hereunder,
then such Lender Party shall promptly notify Canadian Borrowers thereof and such
Lender Party's obligation to make or continue Eurodollar Loans and to convert
BA's, Canadian Base Rate Loans, Canadian Prime Rate Loans, or Bankers'
Acceptances into Eurodollar Loans shall be suspended until such time as such
Lender Party may again make, maintain, and fund Eurodollar Loans (in which case
the provisions of Section 3.5 shall be applicable).

      Section 3.5. Treatment of Affected Loans. If the obligation of any Lender
Party to make a particular Type of Loan or to continue, or to convert Canadian
Loans of any other Type into, Canadian Loans of a particular Type shall be

                                       32
<PAGE>
suspended pursuant to Sections 3.2 and 3.4 hereof (Canadian Loans of such Type
being herein called "Affected Loans" and such Type being herein called the
"Affected Type"), such Lender Party's Affected Loans shall be automatically
converted into Canadian Base Rate Loans with respect to US $ Loans or to
Canadian Prime Rate Loans with respect to C $ Loans on the last day(s) of the
then current Interest Period(s) for Affected Loans (or, in the case of a
Conversion required by Section 3.4 hereof, on such earlier date as such Lender
Party may specify to Canadian Borrowers with a copy to Canadian Agent) and,
unless and until such Lender Party gives notice as provided below that the
circumstances specified in Sections 3.2 or 3.4 hereof that gave rise to such
Conversion no longer exist:

      (a to the extent that such Lender Party's Affected Loans have been so
converted, all payments and prepayments of principal that would otherwise be
applied to such Lender Party's Affected Loans shall be applied instead to its
Canadian Base Rate Loans or Canadian Prime Rate Loans, as applicable; and

      (b all Canadian Loans that would otherwise be made or continued by such
Lender Party as Canadian Loans of the Affected Type shall be made or continued
instead as Canadian Base Rate Loans or Canadian Prime Rate Loans, as applicable,
and all Canadian Loans of such Lender Party that would otherwise be converted
into Canadian Loans of the Affected Type shall be converted instead into (or
shall remain as) Canadian Base Rate Loans or Canadian Prime Rate Loans, as
applicable.

      If such Lender Party gives notice to Canadian Borrowers (with a copy to
Canadian Agent) that the circumstances specified in Section 3.2 or 3.4 hereof
that gave rise to the Conversion of such Lender Party's Affected Loans pursuant
to this Section no longer exist (which such Lender Party agrees to do promptly
upon such circumstances ceasing to exist) at a time when Canadian Loans of the
Affected Type made by other Lender Parties are outstanding, such Lender Party's
Canadian Base Rate Loans or Canadian Prime Rate Loans, as applicable, shall be
automatically converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding Canadian Loans of the Affected Type, to the
extent necessary so that, after giving effect thereto, all Canadian Loans held
by the Lender Parties holding Canadian Loans of the Affected Type and by such
Lender Party are held pro rata (as to principal amounts, Types, and Interest
Periods) in accordance with their Percentage Shares of the Canadian Maximum
Credit Amount.

      Section 3.6. Compensation. Upon the request of any Lender Party, the
applicable Canadian Borrower shall pay to such Lender Party such amount or
amounts as shall be sufficient (in the reasonable opinion of such Lender Party)
to compensate it for any loss, cost, or expense (including loss of anticipated
profits) incurred by it as a result of:

            (i) any payment, prepayment, or Conversion of a Canadian Loan by
      such Canadian Borrower (other than a Canadian Base Rate Loan or a Canadian
      Prime Rate Loan) for any reason, whether voluntary, mandatory, automatic,
      by reason of acceleration, or otherwise, on a date other than the last day
      of the Interest Period for such Loan; or

                                       33
<PAGE>
            (ii) any failure by such Canadian Borrower for any reason
      (including, without limitation, the failure of any condition precedent
      specified in Article IV to be satisfied) to borrow, convert, continue, or
      prepay a Canadian Loan by such Canadian Borrower (other than a Canadian
      Base Rate Loan or a Canadian Prime Rate Loan) on the date for such
      borrowing, Conversion, Continuation, or prepayment specified in the
      relevant notice of borrowing, prepayment, Continuation, or Conversion
      under this Agreement.

      Section 3.7. Change of Applicable Lending Office. Each Lender Party agrees
that, upon the occurrence of any event giving rise to the operation of Sections
3.2 through 3.5 with respect to such Lender Party, it will, if requested by
Canadian Borrowers, use reasonable efforts (subject to overall policy
considerations of such Lender Party) to designate another Applicable Lending
Office, provided that such designation is made on such terms that such Lender
Party and its Applicable Lending Office suffer no economic, legal or regulatory
disadvantage, with the object of avoiding the consequence of the event giving
rise to the operation of any such section. Nothing in this section shall affect
or postpone any of the obligations of Canadian Borrowers or the rights of any
Lender Party provided in Sections 3.2 through 3.5.

      Section 3.8. Replacement of Lenders. If any Lender Party seeks
reimbursement for increased costs under Sections 3.2 through 3.5, or if a
Canadian Borrower is required to increase any sum payable under Section 3.2(d),
then within ninety (90) days thereafter -- provided no Event of Default then
exists -- Canadian Borrowers shall have the right (unless such Lender Party
withdraws its request for additional compensation) to replace such Lender Party
by requiring such Lender Party to assign its Canadian Advances, Canadian Notes,
Canadian LC Obligations, US Loans, US Notes, US LC Obligations and its
commitments hereunder and under the US Agreement to an Eligible Assignee
reasonably acceptable to all Borrowers, provided that: all Obligations of
Borrowers owing to such Lender Party being replaced (including such increased
costs, but excluding principal and accrued interest on the Canadian Notes and
the US Notes being assigned) shall be paid in full to such Lender Party
concurrently with such assignment, and the replacement Eligible Assignee shall
purchase the foregoing by paying to such Lender Party a price equal to the
principal amount thereof plus accrued and unpaid interest thereon. In connection
with any such assignment Canadian Borrowers, Canadian Agent, US Borrower, US
Agent, such Lender Party and the replacement Eligible Assignee shall otherwise
comply with Section 10.6. Notwithstanding the foregoing rights of Canadian
Borrowers under this section, however, Canadian Borrowers may not replace any
Lender Party which seeks reimbursement for increased costs under Section 3.2
through 3.5, or to which Canadian Borrowers are required to increase any sums
payable under Section 3.2(d), unless Canadian Borrowers are at the same time
replacing all Lender Parties which are then seeking such compensation or to
which such sums payable must be increased. In connection with any such
replacement of a Lender Party, the applicable Canadian Borrower shall pay all
costs that would have been due to such Lender Party pursuant to Section 3.6 if
such Lender Party's Canadian Advances had been prepaid at the time of such
replacement.

      Section 3.9. Other Taxes.

                                       34
<PAGE>
      (a) Each Canadian Borrower agrees to pay any and all present or future
stamp or documentary taxes and any other excise or property taxes or charges or
similar levies which arise from any payment made by such Canadian Borrower under
this Agreement or any other Canadian Loan Document or from the execution or
delivery of, or otherwise with respect to, this Agreement or any other Canadian
Loan Document (hereinafter referred to as "Other Taxes").

      (b) Each Canadian Borrower hereby agrees to indemnify each Lender Party
for the full amount of Other Taxes (including, without limitation, any Other
Taxes imposed or asserted by any jurisdiction on amounts payable by such
Canadian Borrower under this section) paid by such Lender Party or Canadian
Agent (as the case may be) and any liability (including penalties, interest, and
expenses) arising therefrom or with respect thereto.

      (c) If either Canadian Borrower is required to pay additional amounts to
or for the account of any Lender Party pursuant to this Section 3.9, then such
Lender Party will agree to use reasonable efforts to change the jurisdiction of
its Applicable Lending Office so as to eliminate or reduce any such additional
payment which may thereafter accrue if such change, in the judgment of such
Lender Party, is not otherwise disadvantageous to such Lender Party.

      (d) If a Lender Party is reimbursed for an amount paid by either Canadian
Borrower pursuant to this Section 3.9, it shall promptly return such amount to
such Canadian Borrower.

      (e) Within thirty (30) days after the date of any payment of Other Taxes,
the applicable Canadian Borrower shall furnish to Canadian Agent the original or
a certified copy of a receipt evidencing such payment.

      (f) Without prejudice to the survival of any other agreement of Canadian
Borrowers hereunder, the agreements and obligations of Canadian Borrowers
contained in this section shall survive the termination of this Agreement and
the payment in full of the Canadian Notes.

      Section 3.10. Currency Conversion and Currency Indemnity.

      (a) Canadian Borrowers shall make payment relative to any Obligation in
the currency (the "Agreed Currency") in which the Obligation was incurred. If
any payment is received on account of any Obligation in any currency (the "Other
Currency") other than the Agreed Currency (whether voluntarily, pursuant to any
Conversion of a Canadian Advance or pursuant to an order or judgment or the
enforcement thereof or the realization of any security or the liquidation of
such Canadian Borrower or otherwise howsoever), such payment shall constitute a
discharge of the liability of a Canadian Borrower hereunder and under the other
Canadian Loan Documents in respect of such Obligation only to the extent of the
amount of the Agreed Currency which the relevant Lender Parties are able to
purchase with the amount of the Other Currency received by it on the Business
Day next following such receipt in accordance with its normal procedures and
after deducting any premium and costs of exchange.

                                       35
<PAGE>
      (b) If, for the purpose of obtaining or enforcing judgment in any court in
any jurisdiction, it becomes necessary to convert into a particular currency
(the "Judgment Currency") any amount due in the Agreed Currency then the
conversion shall be made on the basis of the rate of exchange prevailing on the
next Business Day following the date such judgment is given and in any event the
applicable Canadian Borrower shall be obligated to pay the Lender Parties any
deficiency in accordance with Section 3.10(c). For the foregoing purposes "rate
of exchange" means the rate at which the relevant Lender Parties, as applicable,
in accordance with their normal banking procedures are able on the relevant date
to purchase the Agreed Currency with the Judgment Currency after deducting any
premium and costs of exchange.

      (c) If any Lender Party receives any payment or payments on account of the
liability of either Canadian Borrower hereunder pursuant to any judgment or
order in any Other Currency, and the amount of the Agreed Currency which the
relevant Lender Party is able to purchase on the Business Day next following
such receipt with the proceeds of such payment or payments in accordance with
its normal procedures and after deducting any premiums and costs of exchange is
less than the amount of the Agreed Currency due in respect of such Obligations
immediately prior to such judgment or order, then such Canadian Borrower on
demand shall, and such Canadian Borrower hereby agrees to, indemnify and save
such Lender Party harmless from and against any loss, cost or expense arising
out of or in connection with such deficiency. The agreement of indemnity
provided for in this Section 3.10(c) shall constitute an obligation separate and
independent from all other obligations contained in this Agreement, shall give
rise to a separate and independent cause of action, shall apply irrespective of
any indulgence granted by the Lender Parties or any of them 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 hereunder or under any
judgment or order.

      Section 4.3. Additional Conditions Precedent to all Canadian Advances and

      (b) No Default shall exist at the date of such Canadian Loan or the date

                   ARTICLE V - Representations and Warranties

      To confirm each Lender's understanding concerning Restricted Persons and
Restricted Persons' businesses, properties and obligations and to induce each
Lender to enter into this Agreement and to extend credit hereunder, each
Canadian Borrower represents and warrants to each Lender that:

      Section 5.1. No Default. No event has occurred and is continuing which
constitutes a Default.

      Section 5.2. Organization and Good Standing. Each Canadian Borrower and
each of the Material Subsidiaries of Canadian Borrowers is duly organized,
validly existing and in good standing under the Laws of its jurisdiction of

                                       38
<PAGE>
organization, having all powers required to carry on its business and enter into
and carry out the transactions contemplated hereby. Each Canadian Borrower and
each of the Material Subsidiaries of Canadian Borrowers is duly qualified, in
good standing, and authorized to do business in all other jurisdictions within
Canada wherein the character of the properties owned or held by it or the nature
of the business transacted by it makes such qualification necessary except where
failure to so qualify would not have a Material Adverse Effect. Each Canadian
Borrower and each of the Material Subsidiaries of Canadian Borrowers has taken
all actions and procedures customarily taken in order to enter, for the purpose
of conducting business or owning property, each jurisdiction outside Canada
wherein the character of the properties owned or held by it or the nature of the
business transacted by it makes such actions and procedures desirable except
where failure to so qualify would not have a Material Adverse Effect.

      Section 5.3. Authorization. Each Canadian Borrower has duly taken all
action necessary to authorize the execution and delivery by it of the Canadian
Loan Documents to which it is a party and to authorize the consummation of the
transactions contemplated thereby and the performance of its obligations
thereunder. Each Canadian Borrower is duly authorized to borrow funds hereunder.

      Section 5.4. No Conflicts or Consents. The execution and delivery by each
Canadian Borrower and each Subsidiary of a Canadian Borrower that is a
Restricted Person of the Canadian Loan Documents to which each is a party, the
performance by each of its obligations under such Canadian Loan Documents, and
the consummation of the transactions contemplated by the various Canadian Loan
Documents, do not and will not (i) conflict with any provision of (A) any Law,
(B) the organizational documents or any unanimous shareholders agreement of any
Restricted Person, or (C) any agreement, judgment, license, order or permit
applicable to or binding upon any Restricted Person unless such conflict would
not reasonably be expected to have a Material Adverse Effect, or (ii) result in
the acceleration of any Indebtedness owed by any Restricted Person which would
reasonably be expected to have a Material Adverse Effect, or (iii) result in or
require the creation of any Lien upon any assets or properties of any Restricted
Person which would reasonably be expected to have a Material Adverse Effect,
except as expressly contemplated or permitted in the Canadian Loan Documents.
Except as expressly contemplated in the Canadian Loan Documents no consent,
approval, authorization or order of, and no notice to or filing with, any
Tribunal or third party is required in connection with the execution, delivery
or performance by any Restricted Person of any Canadian Loan Document or to
consummate any transactions contemplated by the Canadian Loan Documents, unless
failure to obtain such consent would not reasonably be expected to have a
Material Adverse Effect.

      Section 5.5.Enforceable Obligations. This Agreement is, and the other
Canadian Loan Documents when duly executed and delivered will be, legal, valid
and binding obligations of each Restricted Person which is a party hereto or
thereto, enforceable in accordance with their terms except as such enforcement
may be limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights.

                                       39

      Section 5.6. Full Disclosure. No certificate, statement or other
information delivered herewith or heretofore by any Canadian Borrower or any
Subsidiary of a Canadian Borrower that is a Restricted Person to any Lender in
connection with the negotiation of this Agreement or in connection with any
transaction contemplated hereby contains any untrue statement of a material fact
or omits to state any material fact known to any such Person (other than
industry-wide risks normally associated with the types of businesses conducted
by Restricted Persons) necessary to make the statements contained herein or
therein not misleading as of the date made or deemed made. There is no fact
known to any such Person (other than industry-wide risks normally associated
with the types of businesses conducted by Restricted Persons) that has not been
disclosed to each Lender in writing which would reasonably be expected to have a
Material Adverse Effect.

      Section 5.7. Litigation. Except as disclosed in the Initial Financial
Statements, in the financial statements delivered to each Lender Party pursuant
to Section 6.2, in the Disclosure Schedule or in a Disclosure Report, there are
no actions, suits or legal, equitable, arbitrative or administrative proceedings
pending, or to the knowledge of any Canadian Borrower threatened, against any
Canadian Borrower or any Subsidiary of a Canadian Borrower that is a Restricted
Person before any Tribunal which would reasonably be expected to have a Material
Adverse Effect, and there are no outstanding judgments, injunctions, writs,
rulings or orders by any such Tribunal against any such Person which would
reasonably be expected to have a Material Adverse Effect.

      Section 5.8. Environmental and Other Laws. Except as disclosed in the
Disclosure Schedule: (a) Canadian Borrowers and each Subsidiary of a Canadian
Borrower that is a Restricted Person are conducting their businesses in material
compliance with all applicable Laws, including Environmental Laws, and have and
are in compliance with all licenses and permits required under any such Laws,
unless failure to so comply would not reasonably be expected to have a Material
Adverse Effect; (b) none of the operations or properties of any Canadian
Borrowers and each Subsidiary of a Canadian Borrower that is a Restricted Person
is the subject of federal, provincial or local investigation evaluating whether
any material remedial action is needed to respond to a release of any Hazardous

storage or disposal at offsite locations) of any Hazardous Materials, unless

Effect; and (c) neither any Canadian Borrower nor any Subsidiary of a Canadian
Borrower that is a Restricted Person (and to the best knowledge of Canadian
Borrowers, no other Person) has filed any notice under any Law indicating that
any such Person is responsible for the improper release into the environment, or
the improper storage or disposal, of any material amount of any Hazardous

Adverse Effect.

      Section 5.9. Canadian Borrowers' Subsidiaries. Neither Canadian Borrower
presently has any Material Subsidiary except those listed in the Disclosure
Schedule or in a Disclosure Report (it being understood that inclusion of a

                                       40
<PAGE>
Subsidiary on the Disclosure Schedule does not mean that such Subsidiary is a

failure to have such title would not have a Material Adverse Effect. Each
Canadian Borrower and each Subsidiary of a Canadian Borrower that is a
Restricted Person possesses all licenses, permits, franchises, patents,
copyrights, trademarks and trade names, and other intellectual property (or
otherwise possesses the right to use such intellectual property) which are
necessary to carry out its business as presently conducted and as presently
proposed to be conducted hereafter except to the extent failure to possess such
licenses, permits, franchises, and intellectual property would not have a
Material Adverse Effect, and no such Restricted Person is in violation in any
material respect of the terms under which it possesses such intellectual
property or the right to use such intellectual property except to the extent any
such violation would not have a Material Adverse Effect.

      Section 5.11. Solvency. Upon giving effect to the issuance of the Canadian
Notes, the execution of the Canadian Loan Documents by Canadian Borrowers and
the consummation of the transactions contemplated hereby, each Canadian Borrower
will be solvent (as such term is used in applicable bankruptcy, liquidation,
receivership, insolvency or similar Laws).

<PAGE>
notwithstanding any provision of this subsection (e) to the contrary, to the
extent that the terms of any such agreement or instrument governing the sale,
pledge or disposal of Margin Stock or utilization of the proceeds of such

      respect thereto reasonably acceptable to the Required Lenders by US
      $250,000,000 or more, unless the same is discharged within thirty days
      after the date of entry thereof or an appeal or appropriate proceeding for
      review thereof is taken within such period and a stay of execution pending
      such appeal is obtained; or

                                       50
<PAGE>
            (v) suffers a levy of distress or execution or possession, or a writ
      or warrant of attachment or any similar process to be issued by any
      Tribunal against all or any part of its property having a book value of at
      least US $250,000,000, and such writ or warrant of attachment or any
      similar process is not stayed or released within thirty days after the
      entry or levy thereof or after any stay is vacated or set aside.

Upon the occurrence of an Event of Default described in subsection (h)(i),
(h)(ii) or (h)(iii) of this section with respect to Canadian Borrowers, all of
the Canadian Obligations shall thereupon be immediately due and payable, without
demand, presentment, notice of demand or of dishonor and nonpayment, protest,
notice of protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Canadian Borrowers and each Restricted Person who at
any time ratifies or approves this Agreement. Upon any such acceleration, any
obligation of any Lender to make any further Canadian Advances, any obligation
of Canadian LC Issuer to issue Letters of Credit hereunder, and any obligation
of Canadian Swing Lender to make any further Canadian Swing Loans shall be
permanently terminated. During the continuance of any other Event of Default,
Canadian Agent at any time and from time to time may (and upon written
instructions from Canadian Required Lenders, Canadian Agent shall), without
notice to Canadian Borrowers or any other Restricted Person, do either or both
of the following: (1) terminate any obligation of Lenders to make Canadian
Advances hereunder, any obligation of Canadian LC Issuer to issue Letters of
Credit hereunder, and any obligation of Canadian Swing Lender to make Canadian
Swing Loans hereunder, and (2) declare any or all of the Canadian Obligations
immediately due and payable, and all such Canadian Obligations shall thereupon
be immediately due and payable, without demand, presentment, notice of demand or
of dishonor and nonpayment, protest, notice of protest, notice of intention to
accelerate, declaration or notice of acceleration, or any other notice or
declaration of any kind, all of which are hereby expressly waived by Canadian
Borrowers and each Restricted Person who at any time ratifies or approves this
Agreement.

      Section 8.2. Remedies. If any Event of Default shall occur and be
continuing, each Lender Party may protect and enforce its rights under the
Canadian Loan Documents by any appropriate proceedings, including proceedings
for specific performance of any covenant or agreement contained in any Canadian
Loan Document, and each Lender Party may enforce the payment of any Canadian
Obligations due it or enforce any other legal or equitable right which it may
have. All rights, remedies and powers conferred upon Lender Parties under the
Canadian Loan Documents shall be deemed cumulative and not exclusive of any
other rights, remedies or powers available under the Canadian Loan Documents or
at Law or in equity.

                           ARTICLE IX - Canadian Agent

      Section 9.1. Appointment, Powers, and Immunities.

      (a) Each Lender hereby irrevocably appoints and authorizes Canadian Agent
to act as its agent under this Agreement and the other Canadian Loan Documents
with such powers and

                                       51
<PAGE>
discretion as are specifically delegated to Canadian Agent by the terms of this
Agreement and the other Canadian Loan Documents, together with such other powers
as are reasonably incidental thereto. The Agent-Related Persons: (i) shall not
have any duties or responsibilities except those expressly set forth in this
Agreement and shall not be trustees or fiduciaries for any Lender; (ii) shall
not be responsible to the Lenders for any recital, statement, representation, or
warranty (whether written or oral) made in or in connection with any Canadian
Loan Document or any certificate or other document referred to or provided for
in, or received by any of them under, any Canadian Loan Document, or for the
value, validity, effectiveness, genuineness, enforceability, or sufficiency of
any Canadian Loan Document, or any other document referred to or provided for
therein or for any failure by any Restricted Person or any other Person to
perform any of its obligations thereunder; (iii) shall not be responsible for or
have any duty to ascertain, inquire into, or verify the performance or
observance of any covenants or agreements by any Restricted Person or the
satisfaction of any condition or to inspect the property (including the books
and records) of any Restricted Person or any of its Subsidiaries or Affiliates
or for the failure of any Restricted Person or Lender Party to perform its
obligations under any Loan Document; (iv) shall not be required to initiate or
conduct any litigation or collection proceedings under any Loan Document; and
(v) shall not be responsible for any action taken or omitted to be taken by it
under or in connection with any Loan Document, except for its own gross
negligence or willful misconduct; provided, however, that no action taken in
accordance with the directions of the number of Lenders herein specified with
respect to a particular action shall be deemed to constitute gross negligence or
willful misconduct for purposes of this Section. Canadian Agent may employ
agents and attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care. Without limiting the generality of the foregoing sentence, the
use of the term "agent" herein and in the other Loan Documents with reference to
US Agent is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable Law. Instead, such
term is used merely as a matter of market custom, and is intended to create or
reflect only an administrative relationship between independent contracting
parties.

      (b) US LC Issuer shall act on behalf of the Lenders with respect to any
Letters of Credit issued by it and the documents associated therewith until such
time (and except for so long) as the US Agent may agree at the request of the
Required Lenders to act for US LC Issuer with respect thereto; provided,
however, that US LC Issuer shall have all of the benefits and immunities (i)
provided to the US Agent in this Article IX with respect to any acts taken or
omissions suffered by US LC Issuer in connection with Letters of Credit issued
by it or proposed to be issued by it and the application and agreements for
letters of credit pertaining to the Letters of Credit as fully as if the term
"US Agent" as used in this Article IX included US LC Issuer with respect to such
acts or omissions, and (ii) as additionally provided herein with respect to US
LC Issuer.

      Section 9.2. Reliance by Canadian Agent.

      (a) Canadian Agent shall be entitled to rely upon any certification,
notice, instrument, writing, or other communication (including, without
limitation, any thereof by telephone or telecopy) believed by it to be genuine
and correct and to have been signed, sent or made by or on

                                       52
<PAGE>
behalf of the proper Person or Persons, and upon advice and statements of legal
counsel (including counsel for any Restricted Person), independent accountants,
and other experts selected by Canadian Agent. Canadian Agent may deem and treat
the payee of any Canadian Note as the holder thereof for all purposes hereof
unless and until Canadian Agent receives and accepts an Assignment and
Assumption executed in accordance with Section 10.6 hereof. Canadian Agent shall
in all cases be fully protected in acting, or in refraining from acting, under
this Agreement or any other Loan Document in accordance with a request or
consent of the Canadian Required Lenders, Canadian Majority Lenders or all
Lenders, if required hereunder, and such request and any action taken or failure
to act pursuant thereto shall be binding upon all Lenders and participants.
Where this Agreement expressly permits or prohibits an action unless the
Canadian Required Lenders, Canadian Majority Lenders or all Lenders otherwise
determine, the Canadian Agent shall, and in all other instances, the Canadian
Agent may, but shall not be required to, initiate any solicitation for the
consent or a vote of the Lenders.

      (b) For purposes of determining compliance with the conditions specified
in Section 4.01, each Lender that has signed this Agreement shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document
or other matter either sent by Canadian Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to a Lender; provided, however,
that Canadian Agent shall not be required to take any action that exposes
Canadian Agent to personal liability or that is contrary to any Loan Document or
applicable Law or unless it shall first be indemnified to its satisfaction by
the Lenders against any and all liability and expense which may be incurred by
it by reason of taking any such action.

      Section 9.3. Defaults. Canadian Agent shall not be deemed to have
knowledge or notice of the occurrence of a Default or Event of Default unless
Canadian Agent has received written notice from a Lender or Canadian Borrowers
specifying such Default or Event of Default and stating that such notice is a
"Notice of Default". In the event that Canadian Agent receives such a notice of
the occurrence of a Default or Event of Default, Canadian Agent shall give
prompt notice thereof to the Lenders. Canadian Agent shall (subject to Section
9.1 hereof) take such action with respect to such Default or Event of Default as
shall reasonably be directed by the Canadian Required Lenders. Notwithstanding
the foregoing, unless and until Canadian Agent shall have received such
directions, Canadian Agent may (but shall not be obligated to) take such action,
or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Lenders.

      Section 9.4. Rights as Lender. With respect to its Percentage Share of the
Canadian Maximum Credit Amount and the Canadian Loans made by it, Canadian Agent
(and any successor acting as Canadian Agent) in its capacity as a Lender
hereunder shall have the same rights and powers hereunder as any other Lender
and may exercise the same as though it were not acting as Canadian Agent, and
the term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include Canadian Agent in its individual capacity. Canadian Agent (and any
successor acting as Canadian Agent) and its Affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to, make
Investments in, provide services to, and generally engage in any kind of
lending, trust, or other business with

                                       53
<PAGE>
any Restricted Person or any of its Subsidiaries or Affiliates as if it were not
acting as Canadian Agent, and Canadian Agent (and any successor acting as
Canadian Agent) and its Affiliates may accept fees and other consideration from
any Restricted Person or any of its Subsidiaries or Affiliates for services in
connection with this Agreement or otherwise without having to account for the
same to the Lenders.

      Section 9.5. Indemnification. The Lenders agree to indemnify each
Agent-Related Person (to the extent not reimbursed under Section 10.4 hereof,
but without limiting the obligations of Canadian Borrowers under such section)
ratably in accordance with their respective Percentage Shares, for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including legal fees), or disbursements of any kind and nature
whatsoever that may be imposed on, incurred by or asserted against Canadian
Agent (including by any Lender) in any way relating to or arising out of any
Canadian Loan Document or the transactions contemplated thereby or any action
taken or omitted by Canadian Agent under any Canadian Loan Document (INCLUDING
ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF CANADIAN AGENT); provided
that no Lender shall be liable for any of the foregoing to the extent they arise
from the gross negligence or willful misconduct of the Person to be indemnified,
and provided further that no action taken in accordance with the directions of
the number of Lenders herein specified with respect to a particular action shall
be deemed to constitute gross negligence or willful misconduct for purposes of
this Section. Without limitation of the foregoing, each Lender agrees to
reimburse Canadian Agent promptly upon demand for its ratable share of any costs
or expenses payable by Canadian Borrowers under Section 10.4, to the extent that
Canadian Agent is not promptly reimbursed for such costs and expenses by
Canadian Borrowers. The agreements contained in this section shall survive
payment in full of the Canadian Loans and all other amounts payable under this
Agreement.

      Section 9.6. Non-Reliance on Canadian Agent and Other Lenders. Each Lender
agrees that it has, independently and without reliance on Canadian Agent or any
other Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of the Canadian Borrowers and their
Subsidiaries and decision to enter into this Agreement and that it will,
independently and without reliance upon Canadian 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 analysis and decisions in taking or not taking
action under the Canadian Loan Documents. Except for notices, reports, and other
documents and information expressly required to be furnished to the Lenders by
Canadian Agent hereunder, Canadian Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition, or business of any Restricted
Person or any of its Subsidiaries or Affiliates that may come into the
possession of Canadian Agent or any of its Affiliates.

      Section 9.7. Administrative Agent in its Individual Capacity. Bank of
America and its Affiliates may make loans to, issue letters of credit for the
account of, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other
business with each

                                       54
<PAGE>
of the Restricted Persons and their respective Affiliates as though Bank of
America were not the Canadian Agent or the Canadian LC Issuer hereunder and
without notice to or consent of Lenders. Lenders acknowledge that, pursuant to
such activities, Bank of America or its Affiliates may receive information
regarding any Restricted Person or its Affiliates (including information that
may be subject to confidentiality obligations in favor of such Restricted Person
or such Affiliate) and acknowledge that the Canadian Agent shall be under no
obligation to provide such information to them. With respect to its Canadian
Loans, Bank of America shall have the same rights and powers under this
Agreement as any other Lender and may exercise such rights and powers as though
it were not the Canadian Agent or the Canadian LC Issuer, and the terms
"Canadian Lender", "Canadian Lenders", "Lender" and "Lenders" include Bank of
America in its individual capacity.

      Section 9.8. Sharing of Set-Offs and Other Payments. Each Lender Party
agrees that if it shall, whether through the exercise of rights under Canadian
Loan Documents or rights of banker's lien, set off, or counterclaim against
Canadian Borrowers or otherwise, obtain payment of a portion of the aggregate
Canadian Obligations owed to it which, taking into account all distributions
made by Canadian Agent under Section 3.1, causes such Lender Party to have
received more than it would have received had such payment been received by
Canadian Agent and distributed pursuant to Section 3.1, then (a) it shall be
deemed to have simultaneously purchased and shall be obligated to purchase
interests in the Canadian Obligations as necessary to cause all Lender Parties
to share all payments as provided for in Section 3.1, and (b) such other
adjustments shall be made from time to time as shall be equitable to ensure that
Canadian Agent and all Lender Parties share all payments of Canadian Obligations
as provided in Section 3.1; provided, however, that nothing herein contained
shall in any way affect the right of any Lender Party to obtain payment (whether
by exercise of rights of banker's lien, set-off or counterclaim or otherwise) of
indebtedness other than the Canadian Obligations. Canadian Borrowers expressly
consent to the foregoing arrangements and agree that any holder of any such
interest may to the fullest extent permitted by Law exercise any and all rights
of banker's lien, set-off, or counterclaim as fully as if such holder were a
holder of the Canadian Obligations in the amount of such interest. If all or any
part of any funds transferred pursuant to this section is thereafter recovered
from the seller under this section which received the same, the purchase
provided for in this section shall be deemed to have been rescinded to the
extent of such recovery, together with interest, if any, if interest is required
pursuant to the order of a Tribunal order to be paid on account of the
possession of such funds prior to such recovery.

      Section 9.9. Investments. Whenever Canadian Agent in good faith determines
that it is uncertain about how to distribute to Lender Parties any funds which
it has received, or whenever Canadian Agent in good faith determines that there
is any dispute among Lender Parties about how such funds should be distributed,
Canadian Agent may choose to defer distribution of the funds which are the
subject of such uncertainty or dispute. If Canadian Agent in good faith believes
that the uncertainty or dispute will not be promptly resolved, or if Canadian
Agent is otherwise required to invest funds pending distribution to Lender
Parties, Canadian Agent shall invest such funds pending distribution; all
interest on any such Investment shall be distributed upon the distribution of
such Investment and in the same

                                       55
<PAGE>
proportion and to the same Persons as such Investment. All moneys received by
Canadian Agent for distribution to Lender Parties (other than to the Person who
is Canadian Agent in its separate capacity as a Lender Party) shall be held by
Canadian Agent pending such distribution solely as Canadian Agent for such
Lender Parties, and Canadian Agent shall have no equitable title to any portion
thereof.

      Section 9.10. Benefit of Article IX. The provisions of this Article (other
than the following Section 9.11) are intended solely for the benefit of Lender
Parties, and no Restricted Person shall be entitled to rely on any such
provision or assert any such provision in a claim or defense against any Lender.
Lender Parties may waive or amend such provisions as they desire without any
notice to or consent of Canadian Borrowers or any Restricted Person.

      Section 9.11. Resignation. Canadian Agent may resign at any time by giving
written notice thereof to Lenders and Canadian Borrowers. Each such notice shall
set forth the date of such resignation. Upon any such resignation, Canadian
Required Lenders shall have the right to appoint a successor Canadian Agent and
if no Default or Event of Default has occurred and is continuing, Canadian
Required Lenders shall obtain the consent of Canadian Borrowers. A successor
must be appointed for any retiring Canadian Agent, and such Canadian Agent's
resignation shall become effective when such successor accepts such appointment.
If, within thirty days after the date of the retiring Canadian Agent's
resignation, no successor Canadian Agent has been appointed and has accepted
such appointment, then the retiring Canadian Agent may appoint a successor
Canadian Agent, which shall be a commercial bank organized or licensed to
conduct a banking or trust business under the Laws of Canada or of any province
thereof and if no Default or Event of Default has occurred and is continuing,
retiring Canadian Agent shall obtain the consent of Canadian Borrowers. Upon the
acceptance of any appointment as Canadian Agent hereunder by a successor
Canadian Agent, the retiring Canadian Agent shall be discharged from its duties
and obligations under this Agreement and the other Canadian Loan Documents.
After any retiring Canadian Agent's resignation hereunder the provisions of this
Article IX shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Canadian Agent under the Canadian Loan
Documents.

      Section 9.12. Lenders to Remain Pro Rata. It is the intent of all parties
hereto that the pro rata share of each Lender in the Tranche B Loans and in the
Canadian Obligations and the related rights and obligations of such Lender under
the Loan Documents shall be substantially the same at all times during the term
of this Agreement. Accordingly, the initial Tranche B Percentage Share of each
Tranche B Lender in the Tranche B Maximum Credit Amount will be the same as the
initial Percentage Share of such Lender in the Canadian Maximum Credit Amount.
All subsequent assignments and adjustments of the interests of the Tranche B
Lenders in the Tranche B Facility and the Canadian Obligations will be made so
as to maintain such a pro rata arrangement; provided that for the purposes of
determining these pro rata shares, any Percentage Share held by any Lender's
Affiliates shall be included in determining the interests of such Lender.

                                       56
<PAGE>
      Section 9.13. Other Agents. None of the Lenders identified on the facing
page or signature pages of this Agreement as a "syndication agent" shall have
any right, power, obligation, liability, responsibility or duty under this
Agreement other than those applicable to all Lenders as such. Without limiting
the foregoing, none of the Lenders so identified shall have or be deemed to have
any fiduciary relationship with any Lender. Each Lender acknowledges that it has
not relied, and will not rely, on any of the Lenders so identified in deciding
to enter into this Agreement or in taking or not taking action hereunder.

                           ARTICLE X - Miscellaneous

      Section 10.1. Waivers and Amendments; Acknowledgments.

      (a) Waivers and Amendments. No failure or delay (whether by course of
conduct or otherwise) by any Lender Party in exercising any right, power or
remedy which such Lender Party may have under any of the Canadian Loan Documents
shall operate as a waiver thereof or of any other right, power or remedy, nor
shall any single or partial exercise by any Lender Party of any such right,
power or remedy preclude any other or further exercise thereof or of any other
right, power or remedy. No waiver of any provision of any Canadian Loan Document
and no consent to any departure therefrom shall ever be effective unless it is
in writing and signed as provided below in this section, and then such waiver or
consent shall be effective only in the specific instances and for the purposes
for which given and to the extent specified in such writing. No notice to or
demand on any Restricted Person shall in any case of itself entitle any
Restricted Person to any other or further notice or demand in similar or other
circumstances. This Agreement and the other Canadian Loan Documents set forth
the entire understanding between the parties hereto with respect to the
transactions contemplated herein and therein and supersede all prior discussions
and understandings with respect to the subject matter hereof and thereof, and no
waiver, consent, release, modification or amendment of or supplement to this
Agreement or the other Canadian Loan Documents shall be valid or effective
against any party hereto unless the same is in writing and signed by (i) if such
party is Canadian Borrowers, by Canadian Borrowers, (ii) if such party is
Canadian Agent or Canadian LC Issuer, by such party, and (iii) if such party is
a Lender, by such Lender or by Canadian Agent on behalf of Lenders with the
written consent of Canadian Required Lenders (which consent has already been
given as to the termination of the Canadian Loan Documents as provided in
Section 10.10). Notwithstanding the foregoing or anything to the contrary
herein, Canadian Agent shall not, without the prior consent of US Majority
Lenders and Canadian Majority Lenders, execute and deliver on behalf of such
Lender any waiver or amendment which would increase the Canadian Maximum Credit
Amount hereunder, except in connection with the Re-allocations described in
Section 1.12. Notwithstanding the foregoing or anything to the contrary herein,
Canadian Agent shall not, without the prior consent of each individual Canadian
Lender, execute and deliver on behalf of such Lender any waiver or amendment
which would: (1) waive any of the conditions specified in Article IV, (2)
increase the maximum amount which such Lender is committed hereunder to lend,
(3) reduce any fees payable to such Lender hereunder, or the principal of, or
interest on, such Lender's Note, (4) postpone any date fixed for any payment of
any such fees, principal or interest,

                                       57
<PAGE>
(5) change the aggregate amount of Percentage Shares which is required for
Canadian Agent, Lenders or any of them to take any particular action under the
Canadian Loan Documents, (6) release either Canadian Borrower, Canadian
Guarantor or Devon Financing ULC (to the extent not otherwise released pursuant
to the terms of the Devon Financing ULC Guaranty executed and delivered to
Canadian Agent) from its obligation to pay such Lender's Advances (it being
understood and agreed that neither any assignment by Devon Financing ULC
contemplated by Section 13 of such Devon Financing ULC Guaranty nor the
termination thereof in accordance with its terms thereof shall constitute a
release of Canadian Borrower or the Canadian Guarantor within the meaning of
this Section 10.1(a) or shall require the consent of any Lender), or (7) amend
this Section 10.1(a), except in connection with the Re-allocations described in
Section 1.12.

      (b) Acknowledgments and Admissions. Each Canadian Borrower hereby
represents, warrants, acknowledges and admits that (i) it has been advised by
counsel in the negotiation, execution and delivery of the Canadian Loan
Documents to which it is a party, (ii) it has made an independent decision to
enter into this Agreement and the other Canadian Loan Documents to which it is a
party, without reliance on any representation, warranty, covenant or undertaking
by Canadian Agent or any Lender, whether written, oral or implicit, other than
as expressly set out in this Agreement or in another Canadian Loan Document
delivered on or after the date hereof, (iii) there are no representations,
warranties, covenants, undertakings or agreements by any Lender as to the
Canadian Loan Documents except as expressly set out in this Agreement or in
another Canadian Loan Document delivered on or after the date hereof, (iv) no
Lender has any fiduciary obligation toward such Canadian Borrower with respect
to any Canadian Loan Document or the transactions contemplated thereby, (v) the
relationship pursuant to the Canadian Loan Documents between such Canadian
Borrower and the other Restricted Persons, on one hand, and each Lender, on the
other hand, is and shall be solely that of debtor and creditor, respectively,
(vi) no partnership or joint venture exists with respect to the Canadian Loan
Documents between any Restricted Person and any Lender, (vii) Canadian Agent is
not such Canadian Borrower's Canadian Agent, but Canadian Agent for Lenders,
(viii) without limiting any of the foregoing, no Canadian Borrower is relying
upon any representation or covenant by any Lender, or any representative
thereof, and no such representation or covenant has been made, that any Lender
will, at the time of an Event of Default or Default, or at any other time,
waive, negotiate, discuss, or take or refrain from taking any action permitted
under the Canadian Loan Documents with respect to any such Event of Default or
Default or any other provision of the Canadian Loan Documents, and (ix) all
Lender Parties have relied upon the truthfulness of the acknowledgments in this
section in deciding to execute and deliver this Agreement and to become
obligated hereunder.

      (c) Joint Acknowledgment. THIS WRITTEN AGREEMENT AND THE OTHER CANADIAN
LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

                                       58
<PAGE>
      THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

      (d) Annual Rates of Interest. For the purposes of the Interest Act
(Canada), whenever interest payable pursuant to this Agreement is calculated on
the basis of a period other than a calendar year (the "Interest Period"), each
rate of interest determined pursuant to such calculation expressed as an annual
rate is equivalent to such rate as so determined multiplied by the actual number
of days in the calendar year in which the same is to be ascertained and divided
by the number of days in the Interest Period.

      Section 10.2. Survival of Agreements; Cumulative Nature. All of Restricted
Persons' various representations, warranties, covenants and agreements in the
Canadian Loan Documents shall survive the execution and delivery of this
Agreement and the other Canadian Loan Documents and the performance hereof and
thereof, including the making or granting of the Canadian Loans and the delivery
of the Canadian Notes and the other Canadian Loan Documents, and shall further
survive until all of the Canadian Obligations are paid in full to each Lender
Party and all of Lender Parties' obligations to Canadian Borrowers are
terminated. All statements and agreements contained in any certificate or other
instrument delivered by any Restricted Person to any Lender Party under any
Canadian Loan Document shall be deemed representations and warranties by each
Canadian Borrower or agreements and covenants of each Canadian Borrower under
this Agreement. The representations, warranties, indemnities, and covenants made
by Restricted Persons in the Canadian Loan Documents, and the rights, powers,
and privileges granted to Lender Parties in the Canadian Loan Documents, are
cumulative, and, except for expressly specified waivers and consents, no
Canadian Loan Document shall be construed in the context of another to diminish,
nullify, or otherwise reduce the benefit to any Lender Party of any such
representation, warranty, indemnity, covenant, right, power or privilege. In
particular and without limitation, no exception set out in this Agreement to any
representation, warranty, indemnity, or covenant herein contained shall apply to
any similar representation, warranty, indemnity, or covenant contained in any
other Canadian Loan Document, and each such similar representation, warranty,
indemnity, or covenant shall be subject only to those exceptions which are
expressly made applicable to it by the terms of the various Canadian Loan
Documents.

      Section 10.3. Notices. All notices, requests, consents, demands and other
communications required or permitted under any Canadian Loan Document shall be
in writing, unless otherwise specifically provided in such Canadian Loan
Document (provided that Canadian Agent may give telephonic notices to the other
Lender Parties), and shall be deemed sufficiently given or furnished if
delivered by personal delivery, by facsimile or other electronic transmission,
by delivery service with proof of delivery, or by registered Canadian mail,
postage prepaid, to each Canadian Borrower and Restricted Persons at the address
of each Canadian Borrower specified on the signature pages hereto and to
Canadian Agent at its address specified on the signature pages hereto and to
each Lender Party at the address specified on Annex II (unless changed by
similar notice in writing given by the particular Person whose address is to be
changed). Any such notice or communication shall be deemed to have been given
(a) in the case of personal delivery or delivery service, as of the date of
first attempted delivery during normal business hours at the address provided
herein, (b) in the case of facsimile or other electronic

                                       59
<PAGE>
transmission, upon receipt, or (c) in the case of registered Canadian mail, five
Business Days after deposit in the mail; provided, however, that no Borrowing
Notice shall become effective until actually received by Canadian Agent.

      Section 10.4. Payment of Expenses; Indemnity.

      (a) Payment of Expenses. Whether or not the transactions contemplated by
this Agreement are consummated, Devon Canada will promptly (and in any event,
within 30 days after any invoice or other statement or notice) pay: (i) all
reasonable costs and expenses incurred by or on behalf of Canadian Agent
(including without limitation, legal fees) in connection with (1) the
negotiation, preparation, execution and delivery of the Canadian Loan Documents,
and any and all consents, waivers or other documents or instruments relating
thereto, (2) the borrowings hereunder and other action reasonably required in
the course of administration hereof, (3) monitoring or confirming (or
preparation or negotiation of any document related to) Canadian Borrowers'
compliance with any covenants or conditions contained in this Agreement or in
any Canadian Loan Document, and (ii) all reasonable costs and expenses incurred
by or on behalf of any Lender Party (including without limitation, legal fees,
consultants' fees and accounting fees) in connection with the defense or
enforcement of any of the Canadian Loan Documents (including this section) or
the defense of any Lender Party's exercise of its rights thereunder.

      (b) INDEMNITY. DEVON CANADA AGREES TO INDEMNIFY EACH AGENT-RELATED PERSON
AND EACH LENDER PARTY, UPON DEMAND, FROM AND AGAINST ANY AND ALL LIABILITIES,
OBLIGATIONS, CLAIMS, LOSSES, DAMAGES, PENALTIES, FINES, ACTIONS, JUDGMENTS,
SUITS, SETTLEMENTS, COSTS, EXPENSES OR DISBURSEMENTS, EXCLUDING PRINCIPAL AND
INTEREST OWING BY NORTHSTAR ENERGY WITH RESPECT TO CANADIAN ADVANCES MADE TO
NORTHSTAR ENERGY, BUT INCLUDING REASONABLE FEES OF LEGAL COUNSEL, ACCOUNTANTS,
EXPERTS AND ADVISORS) OF ANY KIND OR NATURE WHATSOEVER (IN THIS SECTION
COLLECTIVELY CALLED "LIABILITIES AND COSTS") WHICH TO ANY EXTENT (IN WHOLE OR IN
PART) MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST SUCH LENDER PARTY
GROWING OUT OF, RESULTING FROM OR IN ANY OTHER WAY ASSOCIATED WITH THE CANADIAN
LOAN DOCUMENTS AND THE TRANSACTIONS AND EVENTS (INCLUDING THE ENFORCEMENT OR
DEFENSE THEREOF) AT ANY TIME ASSOCIATED THEREWITH OR CONTEMPLATED THEREIN
(WHETHER ARISING IN CONTRACT OR IN TORT OR OTHERWISE AND INCLUDING ANY VIOLATION
OR NONCOMPLIANCE WITH ANY ENVIRONMENTAL LAWS BY ANY AGENT-RELATED PERSON OR ANY
LENDER PARTY OR ANY OTHER PERSON OR ANY LIABILITIES OR DUTIES OF ANY
AGENT-RELATED PERSON OR ANY LENDER PARTY OR ANY OTHER PERSON WITH RESPECT TO
HAZARDOUS MATERIALS FOUND IN OR RELEASED INTO THE ENVIRONMENT).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT
ACT OR OMISSION OF ANY KIND BY ANY AGENT-RELATED PERSON OR LENDER PARTY,

                                       60
<PAGE>
provided only that no Agent-Related Person or Lender Party shall be entitled
under this section to receive indemnification for that portion, if any, of any
liabilities and costs which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment. If any
Person (including Canadian Borrowers or any of their Affiliates) ever alleges
such gross negligence or willful misconduct by any Lender Party, the
indemnification provided for in this section shall nonetheless be paid upon
demand, subject to later adjustment or reimbursement, until such time as a court
of competent jurisdiction enters a final judgment as to the extent and effect of
the alleged gross negligence or willful misconduct. As used in this section the
term "Lender Party" shall refer not only to each Person designated as such in
Section 1.1 but also to each director, officer, agent, attorney, employee,
representative, attorney-in-fact and Affiliate of such Person.

      Section 10.5. Parties in Interest. All grants, covenants and agreements
contained in the Canadian Loan Documents shall bind and inure to the benefit of
the parties thereto and their respective successors and assigns; provided,
however, that, except as set forth in Section 13 of the Devon Financing ULC
Guaranties, no Restricted Person may assign or transfer any of its rights or
delegate any of its duties or obligations under any Canadian Loan Document
without the prior consent of all Lenders (and any attempted assignment or
transfer by any Restricted Person without such consent shall be null and void).
Neither Canadian Borrowers nor any Affiliates of Canadian Borrowers shall
directly or indirectly purchase or otherwise retire any Obligations owed to any
Lender nor will any Lender accept any offer to do so, unless each Lender shall
have received substantially the same offer with respect to the same Percentage
Share of the Obligations owed to it. If Canadian Borrowers or any Affiliate of
Canadian Borrowers at any time purchases some but less than all of the
Obligations owed to all Lender Parties, such purchaser shall not be entitled to
any rights of any Lender under the Canadian Loan Documents unless and until
Canadian Borrowers or their Affiliates have purchased all of the Obligations.

      Section 10.6. Assignments and Participations.

      (a) Any Lender may at any time assign to one or more Eligible Assignees
all or a portion of its rights and obligations under this Agreement (including,
without limitation, all or a portion of its Canadian Loans, Canadian Note, and
its Percentage Share of the Canadian LC Obligations and the Canadian Maximum
Credit Amount); provided, however, that

            (i) each such assignment shall be to an Eligible Assignee;

            (ii) together with each such assignment of its rights and
      obligations under this Agreement, such Lender shall assign the same
      Percentage Share of its rights and obligations with respect to the Tranche
      B Loans under the US Agreement to the same Eligible Assignee or an
      Affiliate of such Eligible Assignee, unless such assignment is being made
      to an Eligible Assignee which is an Affiliate of the assignor;

                                       61
<PAGE>
            (iii) except in the case of such an assignment to another Lender or
      an assignment of all of a Lender's rights and obligations under this
      Agreement, any partial assignment of such Lender's rights and obligations
      under this Agreement and under the US Agreement shall be in a collective
      amount at least equal to US $20,000,000 or an integral multiple of US
      $5,000,000 in excess thereof (in the case of the US Agreement calculated
      with respect to the Maximum US Credit Amount during the Tranche B
      Revolving Period and thereafter calculated with respect to the aggregate
      amount of the Tranche B Facility Usage and the Tranche A Maximum Credit
      Amount, and in the case of the Canadian Credit Agreement calculated with
      respect to the Canadian Maximum Credit Amount during the Canadian
      Revolving Period and thereafter calculated with respect to the Canadian
      Facility Usage);

            (iv) each such assignment by a Lender shall be of a constant, and
      not varying, percentage of all of its rights and obligations under the
      Canadian Loan Documents, excluding, in the case of Bank of America,
      Canadian Swing Loans; and

            (v) the parties to such assignment shall execute and deliver to
      Canadian Agent for its acceptance an Assignment and Assumption in the form
      of Exhibit F hereto, together with any Canadian Note subject to such
      assignment and a processing fee of US$3,500.

Subject to acceptance and recording thereof by Canadian Agent pursuant to
subsection (b) of this Section, from and after the effective date specified in
each Assignment and Assumption, the Eligible Assignee thereunder shall be a
party to this Agreement and, to the extent of the interest assigned by such
Assignment and Assumption, have the obligations, rights, and benefits of a
Lender under this Agreement and the assigning Lender thereunder shall, to the
extent of the interest assigned by such Assignment and Assumption, and be
released from its obligations under this Agreement (and, in the case of an
Assignment and Assumption covering all of the assigning Lender's rights and
obligations under this Agreement, such Lender shall cease to be a party hereto
but shall continue to be entitled to the benefits of Sections 3.2, 3.6, 3.9,
3.10 and 10.4). Upon the consummation of any assignment pursuant to this
section, the assignor, Canadian Agent and Canadian Borrowers shall make
appropriate arrangements so that, if required, new Canadian Notes are issued to
the assignor and the assignee. If the assignee is not incorporated under the
Laws of Canada or a province thereof, it shall deliver to Canadian Borrowers and
Canadian Agent certification as to exemption from deduction or withholding of
Taxes in accordance with Section 3.9 of the US Agreement. Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not
comply with this subsection shall be treated for purposes of this Agreement as a
sale by such Lender of a participation in such rights and obligations in
accordance with subsection (d) of this Section.

      (b) Canadian Agent, acting solely for this purpose as an agent of Canadian
Borrowers, shall maintain at its address referred to in Section 10.3 a copy of
each Assignment and Assumption delivered to and accepted by it and a register
for the recordation of the names and addresses of the Lenders and their
Percentage Share of the Canadian Maximum Credit Amount of, and principal amount
of the Canadian Loans owing to, each Lender from time to time (the "Register").
The entries in the Register shall be conclusive and binding for all purposes,
absent

                                       62
<PAGE>
manifest error, and Canadian Borrowers, Canadian 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, notwithstanding notice to the contrary. The Register
shall be available for inspection by Canadian Borrowers or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

      (c) Upon its receipt of an Assignment and Assumption executed by the
parties thereto, together with any Canadian Note subject to such assignment and
payment of the processing fee, Canadian Agent shall, if such Assignment and
Assumption has been completed and is in substantially the form of Exhibit F
hereto, (i) accept such Assignment and Assumption, (ii) record the information
contained therein in the Register and (iii) give prompt notice thereof to the
parties thereto.

      (d) Any Lender may at any time, without the consent of, or notice to,
Canadian Borrowers or Canadian Agent, sell participations to any Person (other
than a natural person or Canadian Borrowers or any of Canadian Borrowers'
Affiliates or Subsidiaries) in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of the Canadian
Maximum Credit Amount and its Canadian Loans); provided, however, that (i) such
Lender's obligations under this Agreement shall remain unchanged, (ii) such
Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) the participant shall be entitled to the
benefit of the yield protection provisions contained in Article III (provided
that a participant shall not be entitled to receive any greater payment under
Section 3.1 or 3.2 than the applicable Lender would have been entitled to
receive with respect to the participation sold to such participant, unless the
sale of the participation to such participant is made with the Canadian
Borrowers' prior written consent, and (iv) Canadian Borrowers, Canadian 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. A participant that would have been subject to Section 3.9 if it were
a Lender, shall not be entitled to the benefits of Section 3.1 unless Canadian
Borrowers have been notified of the participation sold to such participant, and
such participant agrees, for the benefit of Canadian Borrowers, to comply with
such Section as if it were a Lender) and the right of offset contained in
Section 6.13 (provided that such participant agrees to be subject to Section 9.8
as if it were a Lender). Any agreement or instrument pursuant to which a Lender
sells such a participation shall provide that such Lender shall retain the sole
right to enforce this Agreement and to approve any amendment, modification, or
waiver of any provision of this Agreement (provided that such Lender may agree
that it will not approve amendments, modifications, or waivers decreasing the
amount of principal of or the rate at which interest is payable on such Canadian
Loans or Canadian Note, extending any scheduled principal payment date or date
fixed for the payment of interest on such Canadian Loans or Canadian Note, or
extending its Canadian Maximum Credit Amount without the prior consent of the
participant).

      (e) If the consent of Canadian Borrowers to an assignment or to an
Eligible Assignee is required hereunder, Canadian Borrowers shall be deemed to
have given their consent ten (10) Business Days after the date notice thereof
has been delivered by the assigning Lender (through

                                       63
<PAGE>
Canadian Agent) unless such consent is expressly refused by Canadian Borrowers
prior to such tenth Business Day.

      (f) Notwithstanding anything to the contrary contained herein, if at any
time Bank of America assigns all of its Percentage Share in the Canadian
Obligations and its rights and obligations hereunder pursuant to subsection
10.6(a) above, Bank of America may (i) upon 30 days' notice to Canadian
Borrowers and Canadian Lenders, resign as Canadian LC Issuer and/or (ii) upon 30
days' notice to Canadian Borrowers, resign as Canadian Swing Lender and/or
terminate its commitment to make Canadian Swing Loans. In the event of any such
resignation by Bank of America as Canadian LC Issuer or Canadian Swing Lender or
termination of its commitment to make Canadian Swing Loans, Canadian Borrowers
shall be entitled to appoint from among the Canadian Lenders a successor
Canadian LC Issuer or Canadian Swing Lender hereunder; provided, however, that
no failure by Canadian Borrowers to appoint any such successor shall affect the
resignation of Bank of America as Canadian LC Issuer or Canadian Swing Lender or
termination of its commitment to make Canadian Swing Loans, as the case may be.
If Bank of America resigns as Canadian LC Issuer, it shall retain all the rights
and obligations of Canadian LC Issuer hereunder with respect to all Letters of
Credit outstanding as of the effective date of its resignation as Canadian LC
Issuer and all Canadian LC Obligations with respect thereto (including the right
to require Canadian Lenders to make Canadian Prime Rate Loans or fund
participations in unreimbursed amounts pursuant to Section 2.8. If Bank of
America resigns as Canadian Swing Lender or terminates its commitment to make
Canadian Swing Loans, it shall retain all the rights of Canadian Swing Lender
provided for hereunder with respect to Canadian Swing Loans made by it and
outstanding as of the effective date of such termination, including the right to
require the Canadian Lenders to make Canadian Prime Rate Loans (or other
Advances if requested by a Canadian Borrower) or fund participations in
outstanding Canadian Swing Loans pursuant to Section 1.11.

      (g) Notwithstanding any other provision set forth in this Agreement, any
Lender residing in the United States may at any time assign and pledge all or
any portion of its Canadian Advances and its Canadian Note to any Federal
Reserve Bank as collateral security pursuant to Regulation A and any Operating
Circular issued by such Federal Reserve Bank. No such assignment shall release
the assigning Lender from its obligations hereunder.

      (h) Any Lender may furnish any information concerning Canadian Borrowers
or any of its Subsidiaries in the possession of such Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject, however, to the provisions of Section 10.7 hereof.

      Section 10.7. Confidentiality. Canadian Agent and each Lender (in this
Section each is called a "Lending Party") agrees to keep confidential any
information furnished or made available to it by Canadian Borrowers pursuant to
this Agreement that is marked confidential; provided that nothing herein shall
prevent any Lending Party from disclosing such information (a) to any other
Lending Party or any Affiliate of any Lending Party, or any officer, director,
employee, agent, or advisor of any Lending Party or Affiliate of any Lending
Party, (b) to any other Person if reasonably incidental to the administration of
the credit facility provided herein, (c) as required by any Law, rule, or
regulation, (d) upon the order of any

                                       64
<PAGE>
Tribunal, (e) upon the request or demand of any regulatory agency or authority,
(f) that is or becomes available to the public or that is or becomes available
to any Lending Party other than as a result of a disclosure by any Lending Party
prohibited by this Agreement, (g) in connection with any litigation to which
such Lending Party or any of its Affiliates may be a party, (h) to the extent
necessary in connection with the exercise of any remedy under this Agreement or
any other Canadian Loan Document, and (i) subject to provisions substantially
similar to those contained in this section, to any actual or proposed
participant or assignee.

      Section 10.8. Governing Law; Submission to Process. EXCEPT TO THE EXTENT
THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A CANADIAN LOAN
DOCUMENT, THE CANADIAN LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS
MADE UNDER THE LAWS OF THE PROVINCE OF ALBERTA AND SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE PROVINCE OF ALBERTA
AND THE LAWS OF CANADA APPLICABLE THERETO, WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAW. EACH OF THE PARTIES HEREBY AGREES THAT ANY LEGAL ACTION OR
PROCEEDING AGAINST SUCH CANADIAN BORROWER WITH RESPECT TO THIS AGREEMENT, THE
CANADIAN NOTES OR ANY OF THE CANADIAN LOAN DOCUMENTS MAY BE BROUGHT IN THE
COURTS OF THE PROVINCE OF ALBERTA AND EACH PARTY SUBMITS AND ATTORNS TO, THE
NON-EXCLUSIVE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY WAIVES ANY RIGHT
TO STAY OR TO DISMISS ANY ACTION OR PROCEEDING BROUGHT BEFORE SAID COURTS ON THE
BASIS OF FORUM NON CONVENIENS. NOTHING HEREIN SHALL AFFECT THE RIGHT OF LENDER
PARTIES TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE
RIGHT OF LENDER PARTIES TO BRING PROCEEDINGS AGAINST CANADIAN BORROWERS IN THE
COURTS OF ANY OTHER JURISDICTION.

      Section 10.9. Waiver of Judgment Interest Act (Alberta). To the extent
permitted by Law, the provisions of the Judgment Interest Act (Alberta) shall
not apply to the Canadian Loan Documents and are hereby expressly waived by
Canadian Borrowers.

      Section 10.10. Deemed Reinvestment Not Applicable. For the purposes of the
Interest Act (Canada), the principle of deemed reinvestment of interest shall
not apply to any interest calculation under the Canadian Loan Documents, and the
rates of interest stipulated in this Agreement are intended to be nominal rates
and not effective rates or yields.

      Section 10.11. Limitation on Interest. Lender Parties, Restricted Persons
and any other parties to the Canadian Loan Documents intend to contract in
strict compliance with applicable usury Law from time to time in effect. In
furtherance thereof such Persons stipulate and agree that none of the terms and
provisions contained in the Canadian Loan Documents shall ever be construed to
create a contract to pay, for the use, forbearance or detention of money,
interest in excess of the maximum amount of interest permitted to be charged by
applicable Law from time to time in effect. Neither any Restricted Person nor
any present or future guarantors, endorsers, or other Persons hereafter becoming
liable for payment of any Obligation shall ever be liable for unearned interest
thereon or shall ever be required to pay interest thereon in excess of the
maximum amount that may be lawfully charged

                                       65
<PAGE>
under applicable Law from time to time in effect, and the provisions of this
section shall control over all other provisions of the Canadian Loan Documents
which may be in conflict or apparent conflict herewith. Lender Parties expressly
disavow any intention to charge or collect excessive unearned interest or
finance charges in the event the maturity of any Obligation is accelerated. If
(a) the maturity of any Obligation is accelerated for any reason, (b) any
Obligation is prepaid and as a result any amounts held to constitute interest
are determined to be in excess of the legal maximum, or (c) any Lender or any
other holder of any or all of the Obligations shall otherwise collect moneys
which are determined to constitute interest which would otherwise increase the
interest on any or all of the Obligations to an amount in excess of that
permitted to be charged by applicable Law then in effect, then all sums
determined to constitute interest in excess of such legal limit shall, without
penalty, be promptly applied to reduce the then outstanding principal of the
related Obligations or, at such Lender's or holder's option, promptly returned
to Canadian Borrowers or the other payor thereof upon such determination. In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable Law, Lender
Parties and Restricted Persons (and any other payors thereof) shall to the
greatest extent permitted under applicable Law, and in accordance with generally
accepted actuarial practices and principles, (i) characterize any non-principal
payment as an expense, fee or premium rather than as interest, (ii) exclude
voluntary prepayments and the effects thereof, and (iii) amortize, prorate,
allocate, and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable Law in order to
lawfully charge the maximum amount of interest permitted under applicable Law.
In no event shall the aggregate "interest" (as defined in section 347 of the
Criminal Code (Canada)) payable under the Canadian Loan Documents exceed the
maximum effective annual rate of interest on the "credit advanced" (as defined
in that section) permitted under that section and, if any payment, collection or
demand pursuant to this Agreement in respect of "interest" (as defined in that
section) is determined to be contrary to the provisions of that section, such
payment, collection or demand shall be deemed to have been made by mutual
mistake of Canadian Borrowers, Canadian Agent and Lenders and the amount of such
excess payment or collection shall be refunded to Canadian Borrowers. For
purposes of the Canadian Loan Documents, the effective annual rate of interest
shall be determined in accordance with generally accepted actuarial practices
and principles over the term applicable to the Canadian Obligations on the basis
of annual compounding of the lawfully permitted rate of interest and, in the
event of dispute, a certificate of a Fellow of the Canadian Institute of
Actuaries appointed by Canadian Agent shall be prima facie evidence, for the
purposes of such determination.

      Section 10.12. Termination; Limited Survival. In their sole and absolute
discretion, Canadian Borrowers may at any time that no Canadian Obligations are
owing elect in a written notice delivered to Canadian Agent to terminate this
Agreement. Upon receipt by Canadian Agent of such a notice, if no Canadian
Obligations are then owing this Agreement and all other Canadian Loan Documents
shall thereupon be terminated and the parties thereto released from all
prospective obligations thereunder. Notwithstanding the foregoing or anything
herein to the contrary, any waivers or admissions made by any Restricted Person
in any Canadian Loan Document, any Obligations under Sections 3.2 through 3.6,
and any

                                       66
<PAGE>
obligations which any Person may have to indemnify or compensate any Lender
Party shall survive any termination of this Agreement or any other Canadian Loan
Document. At the request and expense of Canadian Borrowers, Canadian Agent shall
prepare and execute all necessary instruments to reflect and effect such
termination of the Canadian Loan Documents. Canadian Agent is hereby authorized
to execute all such instruments on behalf of all Lenders, without the joinder of
or further action by any Lender.

      Section 10.13. Severability. If any term or provision of any Canadian Loan
Document shall be determined to be illegal or unenforceable all other terms and
provisions of the Canadian Loan Documents shall nevertheless remain effective
and shall be enforced to the fullest extent permitted by applicable Law.

      Section 10.14. Counterparts; Fax. This Agreement may be separately
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to
constitute one and the same Agreement. This Agreement and the Canadian Loan
Documents may be validly executed and delivered by facsimile or other electronic
transmission.

      Section 10.15. Waiver of Jury Trial, Punitive Damages, etc. EACH CANADIAN
BORROWER AND EACH LENDER PARTY HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND
IRREVOCABLY (a) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR
DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH
THE CANADIAN LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR
ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY, IN EACH CASE WHETHER NOW
EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR
OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A
COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE
SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY, (b) WAIVES, TO
THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR
RECOVER IN ANY SUCH LITIGATION ANY "SPECIAL DAMAGES", AS DEFINED BELOW, (c)
CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR
ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH
PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVERS, AND (d) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS
AGREEMENT, THE OTHER CANADIAN LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED
HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS
CONTAINED IN THIS SECTION. AS USED IN THIS SECTION, "SPECIAL DAMAGES" INCLUDES
ALL SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES (REGARDLESS OF HOW
NAMED), BUT DOES NOT INCLUDE ANY PAYMENTS OR FUNDS WHICH ANY PARTY HERETO HAS
EXPRESSLY PROMISED TO PAY OR DELIVER TO ANY OTHER PARTY HERETO.

Exhibits, Schedules, articles, sections, subsections and other subdivisions
refer to the Exhibits, Schedules, articles, sections, subsections and other
