      UNITED DOMINION REALTY TRUST, INC., a Maryland corporation (the "Company",
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to CEDE & Co., as
nominee for The Depository Trust Company, or registered assigns, the Principal
Amount of FIFTY MILLION DOLLARS ($50,000,000), on the Stated Maturity Date
specified above (or any Redemption Date or Repayment Date, each as defined on
the reverse hereof, or any earlier date of acceleration of maturity) (each such
date being hereinafter referred to as the "Maturity Date" with respect to the
principal repayable on such date) and to pay interest thereon (and on any
overdue principal, premium and/or interest to the extent legally enforceable) at
the Interest Rate per annum specified above, until the principal hereof is paid
or duly made available for payment. The Company will pay interest in arrears on
each Interest Payment Date, if any, specified above (each, an "Interest Payment
Date"), commencing with the first Interest Payment Date next succeeding the
Original Issue Date specified above, and on the Maturity Date; provided,
however, that if the Original Issue Date occurs between a Record Date (as
defined below) and the next succeeding Interest Payment Date, interest payments
will commence on the second Interest Payment Date next succeeding the Original
Issue Date to the registered holder (the "Holder") of this Note on the Record
Date with respect to such second Interest Payment Date. Interest on this Note
will be computed on the basis of a 360-day year of twelve 30-day months.

      Interest on this Note will accrue from, and including, the immediately
preceding Interest Payment Date to which interest has been paid or duly provided
for (or from, and including, March 18, 2004 if no interest has been paid or duly
provided for) to, but excluding, the applicable Interest Payment Date or the
Maturity Date, as the case may be (each, an "Interest Period"). The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, subject to certain exceptions described herein, be paid to the person in
whose name this Note (or one or more predecessor Notes, as defined on the
reverse hereof) is registered at the close of business on the fifteenth calendar
day (whether or not a Business Day, as defined below) immediately preceding such
Interest Payment Date (the "Record Date"); provided, however, that interest
payable on the Maturity Date will be payable to the person to whom the principal
hereof and premium, if any, hereon shall be payable. Any such interest not so
punctually paid or duly provided for on any Interest Payment Date other than the
Maturity Date ("Defaulted Interest") shall forthwith cease to be payable to the
Holder on the close of business on any Record Date and, instead, shall be paid
to the person in whose name this Note is registered at the close of business on
a special record date (the "Special Record Date") for the payment of such
Defaulted Interest to be fixed by the Trustee hereinafter referred to, notice
whereof shall be given to the Holder of this Note by the Trustee not less than
10 calendar days prior to such Special Record Date or may be paid at any time in
any other lawful manner, all as more fully provided for in the Indenture.

      Payment of principal, premium, if any, and interest in respect of this
Note due on the Maturity Date will be made in immediately available funds upon
presentation and surrender of this Note (and, with respect to any applicable
repayment of this Note, upon delivery of instructions as contemplated on the
reverse hereof) at the office or agency maintained by the Company for that
purpose in the Borough of Manhattan, The City of New York, currently the office
of the Trustee located at 40 Broad Street, 5(th) Floor, New York, New York
10004, or at such other paying agency in the Borough of Manhattan, The City of
New York, as the Company

                                       2
<PAGE>

may determine; provided, however, that if the Specified Currency (as defined
below) is other than United States dollars and such payment is to be made in the
Specified Currency in accordance with the provisions set forth below, such
payment will be made by wire transfer of immediately available funds to an
account with a bank designated by the Holder hereof at least 15 calendar days
prior to the Maturity Date, provided that such bank has appropriate facilities
therefor and that this Note is presented and surrendered and, if applicable,
instructions are delivered at the aforementioned office or agency maintained by
the Company in time for the Trustee to make such payment in such funds in
accordance with its normal procedures. Payment of interest due on any Interest
Payment Date other than the Maturity Date will be made at the aforementioned
office or agency maintained by the Company or, at the option of the Company, by
check mailed to the address of the person entitled thereto as such address shall
appear in the Security Register maintained by the Trustee; provided, however,
that a Holder of U.S.$10,000,000 (or, if the Specified Currency is other than
United States dollars, the equivalent thereof in the Specified Currency) or more
in aggregate principal amount of Notes (whether having identical or different
terms and provisions) will be entitled to receive interest payments on such
Interest Payment Date by wire transfer of immediately available funds if such
Holder has delivered appropriate wire transfer instructions in writing to the
Trustee not less than 15 calendar days prior to such Interest Payment Date. Any
such wire transfer instructions received by the Trustee shall remain in effect
until revoked by such Holder.

      If any Interest Payment Date or the Maturity Date falls on a day that is
not a Business Day, the required payment of principal, premium, if any, and/or
interest shall be made on the next succeeding Business Day with the same force
and effect as if made on the date such payment was due, and no interest shall
accrue with respect to such payment for the period from and after such Interest
Payment Date or the Maturity Date, as the case may be, to the date of such
payment on the next succeeding Business Day.

      As used herein, "Business Day" means any day, other than a Saturday or
Sunday, that is neither a legal holiday nor a day on which commercial banks are
authorized or required by law, regulation or executive order to close in The
City of New York; provided, however, that if the Specified Currency is other
than United States dollars, such day must not be a day on which commercial banks
are authorized or required by law, regulation or executive order to close in the
Principal Financial Center (as defined below) of the country issuing the
Specified Currency (or, if the Specified Currency is Euro, such day must be a
day on which the Trans-European Automated Real-Time Gross Settlement Express
Transfer (TARGET) System is open). "Principal Financial Center" means the
capital city of the country issuing the Specified Currency, except that with
respect to United States dollars, Australian dollars, Canadian dollars, Euros,
South African rands and Swiss francs, the "Principal Financial Center" shall be
The City of New York, Sydney, Toronto, Johannesburg and Zurich, respectively.

      The Company is obligated to make payment of principal, premium, if any,
and interest in respect of this Note in the Specified Currency specified above
(or, if such Specified Currency is not at the time of such payment legal tender
for the payment of public and private debts in the country issuing such
Specified Currency or, if such Specified Currency is Euro, in the member states
of the European Union that have adopted the single currency in accordance with
the Treaty establishing the European Community, as amended by the Treaty on
European Union, then in the currency which is at the time of such payment legal
tender in the related country or in the

                                       3
<PAGE>

adopting member states of the European Union) (the "Specified Currency"). If the
Specified Currency is other than United States dollars, except as otherwise
provided below, any such amounts so payable by the Company will be converted by
the Exchange Rate Agent specified above into United States dollars for payment
to the Holder of this Note.

      If the Specified Currency is other than United States dollars, the Holder
of this Note may elect to receive any amounts payable hereunder in such
Specified Currency. If the Holder of this Note shall not have duly made an
election to receive all or a specified portion of any payment of principal,
premium, if any, and/or interest in respect of this Note in the Specified
Currency, any United States dollar amount to be received by the Holder of this
Note will be based on the highest bid quotation in The City of New York received
by the Exchange Rate Agent at approximately 11:00 A.M., New York City time, on
the second Business Day preceding the applicable payment date from three
recognized foreign exchange dealers (one of whom may be the Exchange Rate Agent)
selected by the Exchange Rate Agent and approved by the Company for the purchase
by the quoting dealer of the Specified Currency for United States dollars for
settlement on such payment date in the aggregate amount of the Specified
Currency payable to all Holders of Notes scheduled to receive United States
dollar payments and at which the applicable dealer commits to execute a
contract. All currency exchange costs will be borne by the Holder of this Note
by deductions from such payments. If three such bid quotations are not
available, payments on this Note will be made in the Specified Currency.

      If the Specified Currency is other than United States dollars, the Holder
of this Note may elect to receive all or a specified portion of any payment of
principal, premium, if any, and/or interest in respect of this Note in the
Specified Currency by submitting a written request for such payment to the
Trustee at its corporate trust office in The City of New York on or prior to the
applicable Record Date or at least 15 calendar days prior to the Maturity Date,
as the case may be. Such written request may be mailed or hand delivered or sent
by cable, telex or other form of facsimile transmission. The Holder of this Note
may elect to receive all or a specified portion of all future payments in the
Specified Currency in respect of such principal, premium, if any, and/or
interest and need not file a separate election for each payment. Such election
will remain in effect until revoked by written notice to the Trustee, but
written notice of any such revocation must be received by the Trustee on or
prior to the applicable Record Date or at least 15 calendar days prior to the
Maturity Date, as the case may be.

      If the Specified Currency is other than United States dollars and the
Holder of this Note shall have duly made an election to receive all or a
specified portion of any payment of principal, premium, if any, and/or interest
in respect of this Note in the Specified Currency, but the Specified Currency is
not available due to the imposition of exchange controls or other circumstances
beyond the control of the Company, the Company will be entitled to satisfy its
obligations to the Holder of this Note by making such payment in United States
dollars on the basis of the Market Exchange Rate (as defined below) determined
by the Exchange Rate Agent on the second Business Day prior to such payment date
or, if such Market Exchange Rate is not then available, on the basis of the most
recently available Market Exchange Rate. The "Market Exchange Rate" for the
Specified Currency means the noon dollar buying rate in The City of New York for
cable transfers for the Specified Currency as certified for customs purposes
(or, if not so certified, as otherwise determined) by the Federal Reserve Bank
of New York. Any

                                       4
<PAGE>

payment made in United States dollars under such circumstances shall not
constitute an Event of Default (as defined in the Indenture).

      All determinations referred to above made by the Exchange Rate Agent shall
be at its sole discretion and shall, in the absence of manifest error, be
conclusive for all purposes and binding on the Holder of this Note.

      The Company agrees to indemnify the Holder of any Note against any loss
incurred by such Holder as a result of any judgment or order being given or made
against the Company for any amount due hereunder and such judgment or order
requiring payment in a currency (the "Judgment Currency") other than the
Specified Currency, and as a result of any variation between (i) the rate of
exchange at which the Specified Currency amount is converted into the Judgment
Currency for the purpose of such judgment or order, and (ii) the rate of
exchange at which such Holder, on the date of payment of such judgment or order,
is able to purchase the Specified Currency with the amount of the Judgment
Currency actually received by such Holder, as the case may be. The foregoing
indemnity constitutes a separate and independent obligation of the Company and
continues in full force and effect notwithstanding any such judgment or order as
aforesaid. The term "rate of exchange" includes any premiums and costs of
exchange payable in connection with the purchase of, or conversion into, the
relevant currency.

      Reference is hereby made to the further provisions of this Note set forth
on the reverse hereof and, if so specified on the face hereof, in an Addendum
hereto, which further provisions shall have the same force and effect as if set
forth on the face hereof.

      Notwithstanding the foregoing, if an Addendum is attached hereto or
"Other/Additional Provisions" apply to this Note as specified above, this Note
shall be subject to the terms set forth in such Addendum or such
"Other/Additional Provisions".

      Unless the Certificate of Authentication hereon has been executed by the
Trustee by manual signature, this Note shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

                       UNITED DOMINION REALTY TRUST, INC.

                                MEDIUM-TERM NOTE
                                  (FIXED RATE)

      This Note is one of a duly authorized series of Debt Securities (the "Debt
Securities") of the Company issued and to be issued under an Indenture, dated as
of November 1, 1995, as amended, modified or supplemented from time to time (the
"Indenture"), between the Company and Wachovia Bank, National Association,
(formerly known as First Union National Bank of Virginia) as trustee (the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Debt
Securities, and of the terms upon which the Debt Securities are, and are to be,
authenticated and delivered. This Note is one of the series of Debt Securities
designated as "Medium-Term Notes Due Nine Months or More From Date of Issue"
(the "Notes"). All terms used but not defined in this Note or in an Addendum
hereto shall have the meanings assigned to such terms in the Indenture or on the
face hereof, as the case may be.

      This Note is issuable only in registered form without coupons in minimum
denominations of U.S. $1,000 and integral multiples thereof or other Authorized
Denomination specified on the face hereof.

      This Note will not be subject to any sinking fund and, unless otherwise
specified on the face hereof in accordance with the provisions of the following
two paragraphs, will not be redeemable or repayable prior to the Stated Maturity
Date.

      This Note will be subject to redemption at the option of the Company on
any date on or after the Initial Redemption Date, if any, specified on the face
hereof, in whole or from time to time in part in increments of U.S. $1,000 or
other integral multiple of an Authorized Denomination (provided that any
remaining principal amount hereof shall be at least U.S. $1,000 or such other
minimum Authorized Denomination), at the Redemption Price (as defined below),
together with unpaid interest accrued thereon to the date fixed for redemption
(the "Redemption Date"), on written notice given to the Holder hereof (in
accordance with the provisions of the Indenture) not more than 60 nor less than
30 calendar days prior to the Redemption Date. The "Redemption Price" shall be
the Initial Redemption Percentage specified on the face hereof (as adjusted by
the Annual Redemption Percentage Reduction, if any, specified on the face hereof
as set forth below) multiplied by the unpaid principal amount of this Note to be
redeemed. The Initial Redemption Percentage shall decline at each anniversary of
the Initial Redemption Date by the Annual Redemption Percentage Reduction, if
any, until the Redemption Price is 100% of unpaid principal amount to be
redeemed. In the event of redemption of this Note in part only, a new Note of
like tenor for the unredeemed portion hereof and otherwise having the same terms
and provisions as this Note shall be issued by the Company in the name of the
Holder hereof upon the presentation and surrender hereof.

                                       7
<PAGE>

      This Note will be subject to repayment by the Company at the option of the
Holder hereof on the Optional Repayment Date(s), if any, specified on the face
hereof, in whole or in part in increments of U.S. $1,000 or other integral
multiple of an Authorized Denomination (provided that any remaining principal
amount hereof shall be at least U.S. $1,000 or such other minimum Authorized
Denomination), at a repayment price equal to 100% of the unpaid principal amount
to be repaid, together with unpaid interest accrued thereon to the date fixed
for repayment (the "Repayment Date"). For this Note to be repaid, the Trustee
must receive at its corporate trust office not more than 60 nor less than 30
calendar days prior to the Repayment Date, such Note and instructions to such
effect forwarded by the Holder hereof. Exercise of such repayment option by the
Holder hereof shall be irrevocable. In the event of repayment of this Note in
part only, a new Note of like tenor for the unrepaid portion hereof and
otherwise having the same terms and provisions as this Note shall be issued by
the Company in the name of the Holder hereof upon the presentation and surrender
hereof.

      If this Note is specified on the face hereof to be a Discount Note, the
amount payable to the Holder of this Note in the event of redemption, repayment
or acceleration of maturity will be equal to the sum of (1) the Issue Price
specified on the face hereof (increased by any accruals of the Discount, as
defined below) and, in the event of any redemption of this Note (if applicable),
multiplied by the Initial Redemption Percentage (as adjusted by the Annual
Redemption Percentage Reduction, if applicable) and (2) any unpaid interest
accrued thereon to the Redemption Date, Repayment Date or date of acceleration
of maturity, as the case may be. The difference between the Issue Price and 100%
of the principal amount of this Note is referred to herein as the "Discount".

      For purposes of determining the amount of Discount that has accrued as of
any Redemption Date, Repayment Date or date of acceleration of maturity of this
Note, such Discount will be accrued so as to cause the yield on the Note to be
constant. The constant yield will be calculated using a 30-day month, 360-day
year convention, a compounding period that, except for the Initial Period (as
defined below), corresponds to the shortest period between Interest Payment
Dates (with ratable accruals within a compounding period) and an assumption that
the maturity of this Note will not be accelerated. If the period from the
Original Issue Date to the initial Interest Payment Date (the "Initial Period")
is shorter than the compounding period for this Note, a proportionate amount of
the yield for an entire compounding period will be accrued. If the Initial
Period is longer than the compounding period, then such period will be divided
into a regular compounding period and a short period, with the short period
being treated as provided in the preceding sentence.

      In addition to the covenants set forth in the Indenture, the Company is
required to maintain Total Unencumbered Assets (as defined below) of not less
than 150% of the aggregate outstanding principal amount of the Company's
Unsecured Debt (as defined below). For purposes of this requirement, the
following capitalized terms shall be defined as follows:

      "Total Unencumbered Assets" means the sum of (i) those Undepreciated Real
Estate Assets (as defined below) not subject to an encumbrance and (ii) all
other assets of the Company and its Subsidiaries (as defined below) not subject
to encumbrance determined in accordance with generally accepted accounting
principles (but excluding accounts receivable and intangibles).

                                       8
<PAGE>

      "Subsidiaries" means a corporation, a limited liability company or a
partnership a majority of the outstanding voting stock, limited liability
company or partnership interests, as the case may be, of which is owned,
directly or indirectly, by the Company or by one or more other Subsidiaries of
the Company. For purposes of this definition, "voting stock" means stock having
voting power for the election of directors, managing members or trustees,
whether at all times or only so long as no senior class of stock has such voting
power by reason of any contingency.

      "Undepreciated Real Estate Assets" as of any date means the original cost
plus capital improvements of real estate assets of the Company and its
Subsidiaries determined in accordance with generally accepted accounting
principles.

      "Unsecured Debt" means debt of the Company or any Subsidiary which is not
secured by any mortgage, lien, charge, pledge or security interest of any kind
upon any of their properties.

      If an Event of Default shall occur and be continuing, the principal of the
Notes may, and in certain cases shall, be accelerated in the manner and with the
effect provided in the Indenture.

      The Indenture contains provisions for defeasance of (i) the entire
indebtedness of the Notes or (ii) certain covenants and Events of Default with
respect to the Notes, in each case upon compliance with certain conditions set
forth therein, which provisions apply to the Notes.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debt Securities at any time by the
Company and the Trustee with the consent of the Holders of a majority of the
aggregate principal amount of all Debt Securities at the time outstanding and
affected thereby. The Indenture also contains provisions permitting the Holders
of a majority of the aggregate principal amount of the outstanding Debt
Securities of any series, on behalf of the Holders of all such Debt Securities,
to waive compliance by the Company with certain provisions of the Indenture.
Furthermore, provisions in the Indenture permit the Holders of a majority of the
aggregate principal amount of the outstanding Debt Securities of any series, in
certain instances, to waive, on behalf of all of the Holders of Debt Securities
of such series, certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Note shall be
conclusive and binding upon such Holder and upon all future Holders of this Note
and other Notes issued upon the registration of transfer hereof or in exchange
heretofore or in lieu hereof, whether or not notation of such consent or waiver
is made upon this Note.

      No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay principal, premium, if any, and interest in
respect of this Note at the times, places and rate or formula, and in the coin
or currency, herein prescribed.

      As provided in the Indenture and subject to certain limitations therein
and herein set forth, the transfer of this Note is registrable in the Security
Register of the Company upon surrender of this Note for registration of transfer
at the office or agency of the Company in any place where the principal hereof
and any premium or interest hereon are payable, duly endorsed by, or accompanied
by a written instrument of transfer in form satisfactory to the Company and

                     US COMMITMENTS AND US CREDIT EXTENSION

         2.01     US COMMITTED LOANS. Subject to the terms and conditions set
forth herein, each Lender severally agrees to make loans (each such loan, a "US
Committed Loan") to the US Borrower from time to time, on any Business Day
during the Availability Period, in an aggregate amount not to exceed at any time
outstanding the amount of the US Commitment of such Lender; provided, however,
that after giving effect to any US Committed Borrowing, (i) the Total US
Outstandings shall not exceed the Aggregate US Commitments, and (ii) the
aggregate Outstanding Amount of the US Committed Loans of any Lender, plus such
Lender's Pro Rata Share of the Outstanding Amount of all US L/C Obligations,
plus such Lender's Pro Rata Share of the Outstanding Amount of all US Swing Line
Loans shall not exceed the US Commitment of such Lender. Within the limits of
the US Commitment of each Lender, and subject to the other terms and conditions
hereof, the US Borrower may borrow under this Section 2.01, prepay under Section
2.06, and reborrow under this Section 2.01. US Committed Loans may be US Base
Rate Loans or US Eurodollar Rate Committed Loans, as further provided herein.

         2.02     US BORROWINGS, CONVERSIONS AND CONTINUATIONS OF US COMMITTED
LOANS.

         (a)      Each US Committed Borrowing, each conversion of US Committed
Loans from one Type to the other, and each continuation of US Eurodollar Rate
Committed Loans shall be made upon the US Borrower's irrevocable notice to
(except as provided in Section 5.03(a)) the Administrative Agent, which may be
given by telephone. Each such notice must be received by the Administrative
Agent not later than 11:00 a.m. (i) two Business Days prior to the requested
date of any US Borrowing of, conversion to or continuation of US Eurodollar Rate
Committed Loans or of any conversion of US Eurodollar Rate Committed Loans to US
Base Rate Committed Loans, and (ii) on the requested date of any US Borrowing of
US Base Rate Committed Loans. Each telephonic notice by the US Borrower pursuant
to this Section 2.02(a) must be confirmed promptly by delivery to the
Administrative Agent of a written US Committed Loan Notice, appropriately
completed and signed by a Responsible Officer of the US Borrower. Each US
Borrowing of, conversion to or continuation of US Eurodollar Rate Committed
Loans shall be in a principal amount of US $5,000,000 or a whole multiple of US
$1,000,000 in excess thereof. Except as provided in Sections 2.04(c) and
2.05(c), each US Borrowing of or conversion to US Base Rate Committed Loans
shall be in a principal amount of US $1,000,000

                                                          DEVON CREDIT AGREEMENT

                                       36
<PAGE>

or a whole multiple of US $100,000 in excess thereof. Each US Committed Loan
Notice (whether telephonic or written) shall specify (i) whether the US Borrower
is requesting a US Committed Borrowing, a conversion of US Committed Loans from
one Type to the other, or a continuation of US Eurodollar Rate Committed Loans,
(ii) the requested date of the US Borrowing, conversion or continuation, as the
case may be (which shall be a Business Day), (iii) the principal amount of US
Committed Loans to be borrowed, converted or continued, (iv) the Type of US
Committed Loans to be borrowed or to which existing US Committed Loans are to be
converted, and (v) if applicable, the duration of the Interest Period with
respect thereto. If the US Borrower fails to specify a Type of US Committed Loan
in a US Committed Loan Notice or if the US Borrower fails to give a timely
notice requesting a conversion or continuation, then the applicable US Committed
Loans shall be made as, or converted to, US Base Rate Loans. Any such automatic
conversion to US Base Rate Loans shall be effective as of the last day of the
Interest Period then in effect with respect to the applicable US Eurodollar Rate
Committed Loans. If the US Borrower requests a US Committed Borrowing of,
conversion to, or continuation of US Eurodollar Rate Committed Loans in any such
US Committed Loan Notice, but fails to specify an Interest Period, it will be
deemed to have specified an Interest Period of one month.

         (b)      Following receipt of a US Committed Loan Notice, the
Administrative Agent shall promptly notify each Lender of the amount of its Pro
Rata Share of the applicable US Committed Loans, and if no timely notice of a
conversion or continuation is provided by the US Borrower, the Administrative
Agent shall notify each Lender of the details of any automatic conversion to US
Base Rate Loans described in the preceding subsection. In the case of a US
Committed Borrowing, each Lender shall make the amount of its US Committed Loan
available to the Administrative Agent in immediately available funds at the
Administrative Agent's Office not later than 1:00 p.m. on the Business Day
specified in the applicable US Committed Loan Notice. Upon satisfaction of the
applicable conditions set forth in Section 6.02 (and, if such US Borrowing is
the initial US Credit Extension, Section 6.01), the Administrative Agent shall
make all funds so received available to the US Borrower in like funds as
received by the Administrative Agent either by (i) crediting the account of the
US Borrower on the books of Bank of America with the amount of such funds or
(ii) wire transfer of such funds, in each case in accordance with instructions
provided to (and reasonably acceptable to) the Administrative Agent by the US
Borrower; provided, however, that if, on the date the US Committed Loan Notice
with respect to such US Borrowing is given by the US Borrower, there are US L/C
Borrowings outstanding, then the proceeds of such US Borrowing, first, shall be
applied, to the payment in full of any such US L/C Borrowings, and second, shall
be made available to the US Borrower as provided above.

         (c)      Except as otherwise provided herein, a US Eurodollar Rate
Committed Loan may be continued or converted only on the last day of an Interest
Period for such US Eurodollar Rate Committed Loan. During the existence of a
Default, no Loans may be requested as, converted to or continued as US
Eurodollar Rate Committed Loans without the consent of the US Required Lenders.

         (d)      The Administrative Agent shall promptly notify the US Borrower
and the Lenders of the interest rate applicable to any Interest Period for US
Eurodollar Rate Committed Loans

                                                          DEVON CREDIT AGREEMENT

                                       37
<PAGE>

upon determination of such interest rate. The determination of the US Dollar
Eurodollar Rate by the Administrative Agent shall be conclusive in the absence
of manifest error. At any time that US Base Rate Loans are outstanding, the
Administrative Agent shall notify the US Borrower and the Lenders of any change
in Bank of America's prime rate used in determining the US Base Rate promptly
following the public announcement of such change.

         (e)      After giving effect to all US Committed Borrowings, all
conversions of US Committed Loans from one Type to the other, and all
continuations of US Committed Loans as the same Type, there shall not be more
than ten Interest Periods in effect with respect to US Committed Loans.

         2.03     US BID LOANS.

         (a)      General. Subject to the terms and conditions set forth herein,
each Lender agrees that the US Borrower may from time to time request the
Lenders to submit offers to make loans (each such loan, a "US Bid Loan") for
requested maturities of thirty (30) days or more to the US Borrower prior to the
Maturity Date pursuant to this Section 2.03; provided, however, that after
giving effect to any US Bid Borrowing, the Total US Outstandings shall not
exceed the Aggregate US Commitments. There shall not be more than five different
Interest Periods in effect with respect to US Bid Loans at any time.

         (b)      Requesting US Competitive Bids. The US Borrower may request
the submission of US Competitive Bids by delivering a US Bid Request to the
Administrative Agent not later than 12:00 noon (i) one Business Day prior to the
requested date of any US Bid Borrowing that is to consist of US Absolute Rate
Loans, or (ii) four Business Days prior to the requested date of any US Bid
Borrowing that is to consist of US Eurodollar Margin Bid Loans. Each US Bid
Request shall specify (i) the requested date of the US Bid Borrowing (which
shall be a Business Day), (ii) the aggregate principal amount of US Bid Loans
requested (which must be US $5,000,000 or a whole multiple of US $1,000,000 in
excess thereof), (iii) the Type of US Bid Loans requested, and (iv) the duration
of the Interest Period with respect thereto, and shall be signed by a
Responsible Officer of the US Borrower. No US Bid Request shall contain a
request for (i) more than one Type of US Bid Loan or (ii) US Bid Loans having
more than three different Interest Periods. Unless the Administrative Agent
otherwise agrees in its sole and absolute discretion, the US Borrower may not
submit a US Bid Request if it has submitted another US Bid Request within the
prior five Business Days.

         (c)      Submitting US Competitive Bids.

                  (i)      The Administrative Agent shall promptly notify each
         Lender of each US Bid Request received by it from the US Borrower and
         the contents of such US Bid Request.

                  (ii)     Each Lender may (but shall have no obligation to)
         submit a US Competitive Bid containing an offer to make one or more US
         Bid Loans in response to such US Bid Request. Such US Competitive Bid
         must be delivered to the Administrative Agent not later than 10:30 a.m.
         (A) on the requested date of any US Bid Borrowing that

                                                          DEVON CREDIT AGREEMENT

                                       38
<PAGE>

         is to consist of US Absolute Rate Loans, and (B) three Business Days
         prior to the requested date of any US Bid Borrowing that is to consist
         of US Eurodollar Margin Bid Loans; provided, however, that any US
         Competitive Bid submitted by Bank of America in its capacity as a
         Lender in response to any US Bid Request must be submitted to the
         Administrative Agent not later than 10:15 a.m. on the date on which US
         Competitive Bids are required to be delivered by the other Lenders in
         response to such US Bid Request. Each US Competitive Bid shall specify
         (A) the proposed date of the US Bid Borrowing; (B) the principal amount
         of each US Bid Loan for which such US Competitive Bid is being made,
         which principal amount (x) may be equal to, greater than or less than
         the US Commitment of the bidding Lender, (y) must be US $5,000,000 or a
         whole multiple of US $1,000,000 in excess thereof, and (z) may not
         exceed the principal amount of US Bid Loans for which US Competitive
         Bids were requested; (C) if the proposed US Bid Borrowing is to consist
         of US Absolute Rate Loans, the Absolute Rate offered for each such US
         Bid Loan and the Interest Period applicable thereto; (D) if the
         proposed US Bid Borrowing is to consist of US Eurodollar Margin Bid
         Loans, the US Eurodollar Bid Margin with respect to each such US
         Eurodollar Margin Bid Loan and the Interest Period applicable thereto;
         and (E) the identity of the bidding Lender.

                  (iii)    Any US Competitive Bid shall be disregarded if it (A)
         is received after the applicable time specified in clause (ii) above,
         (B) is not substantially in the form of a US Competitive Bid as
         specified herein, (C) contains qualifying, conditional or similar
         language, (D) proposes terms other than or in addition to those set
         forth in the applicable US Bid Request, or (E) is otherwise not
         responsive to such US Bid Request. Any Lender may correct a US
         Competitive Bid containing a manifest error by submitting a corrected
         US Competitive Bid (identified as such) not later than the applicable
         time required for submission of US Competitive Bids. Any such
         submission of a corrected US Competitive Bid shall constitute a
         revocation of the US Competitive Bid that contained the manifest error.
         The Administrative Agent may, but shall not be required to, notify any
         Lender of any manifest error it detects in such Lender's US Competitive
         Bid.

                  (iv)     Subject only to the provisions of Sections 5.02, 5.03
         and 6.02 and clause (iii) above, each US Competitive Bid shall be
         irrevocable.

         (d)      Notice to US Borrower of US Competitive Bids. Not later than
11:00 a.m. (i) on the requested date of any US Bid Borrowing that is to consist
of US Absolute Rate Loans, or (ii) three Business Days prior to the requested
date of any US Bid Borrowing that is to consist of US Eurodollar Margin Bid
Loans, the Administrative Agent shall notify the US Borrower of the identity of
each Lender that has submitted a US Competitive Bid that complies with Section
2.03(c) and of the terms of the offers contained in each such US Competitive
Bid.

         (e)      Acceptance of US Competitive Bids. Not later than 11:30 a.m.
(i) on the requested date of any US Bid Borrowing that is to consist of US
Absolute Rate Loans, and (ii) three Business Days prior to the requested date of
any US Bid Borrowing that is to consist of US Eurodollar Margin Bid Loans, the
US Borrower shall notify the Administrative Agent of its acceptance or rejection
of the offers notified to it pursuant to Section 2.03(d). The US Borrower shall
be under no obligation to accept any US Competitive Bid and may choose to reject
all US

                                                          DEVON CREDIT AGREEMENT

                                       39
<PAGE>

Competitive Bids. In the case of acceptance, such notice shall specify the
aggregate principal amount of US Competitive Bids for each Interest Period that
is accepted. The US Borrower may accept any US Competitive Bid in whole or in
part; provided that:

                  (i)      the aggregate principal amount of each US Bid
         Borrowing may not exceed the applicable amount set forth in the related
         US Bid Request;

                  (ii)     the principal amount of each US Bid Loan must be US
         $5,000,000 or a whole multiple of US $1,000,000 in excess thereof;

                  (iii)    the acceptance of offers may be made only on the
         basis of ascending Absolute Rates or US Eurodollar Bid Margins within
         each Interest Period; and

                  (iv)     the US Borrower may not accept any offer that is
         described in Section 2.03(c)(iii) or that otherwise fails to comply
         with the requirements hereof.

         (f)      Procedure for Identical US Bids. If two or more Lenders have
submitted US Competitive Bids at the same Absolute Rate or US Eurodollar Bid
Margin, as the case may be, for the same Interest Period, and the result of
accepting all of such US Competitive Bids in whole (together with any other US
Competitive Bids at lower Absolute Rates or US Eurodollar Bid Margins, as the
case may be, accepted for such Interest Period in conformity with the
requirements of Section 2.03(e)(iii)) would be to cause the aggregate
outstanding principal amount of the applicable US Bid Borrowing to exceed the
amount specified therefor in the related US Bid Request, then, unless otherwise
agreed by the US Borrower, the Administrative Agent and such Lenders, such US
Competitive Bids shall be accepted as nearly as possible in proportion to the
amount offered by each such Lender in respect of such Interest Period, with such
accepted amounts being rounded to the nearest whole multiple of US $1,000,000.

         (g)      Notice to Lenders of Acceptance or Rejection of US Bids. The
Administrative Agent shall promptly notify each Lender having submitted a US
Competitive Bid whether or not its offer has been accepted and, if its offer has
been accepted, of the amount of the US Bid Loan or US Bid Loans to be made by it
on the date of the applicable US Bid Borrowing. Any US Competitive Bid or
portion thereof that is not accepted by the US Borrower by the applicable time
specified in Section 2.03(e) shall be deemed rejected.

         (h)      Notice of US Dollar Eurodollar Rate. If any US Bid Borrowing
is to consist of US Eurodollar Margin Bid Loans, the Administrative Agent shall
determine the US Dollar Eurodollar Rate for the relevant Interest Period, and
promptly after making such determination, shall notify the US Borrower and the
Lenders that will be participating in such US Bid Borrowing of such US Dollar
Eurodollar Rate.

         (i)      Funding of US Bid Loans. Each Lender that has received notice
pursuant to Section 2.03(g) that all or a portion of its US Competitive Bid has
been accepted by the US Borrower shall make the amount of its US Bid Loan(s)
available to the Administrative Agent in immediately available funds at the
Administrative Agent's Office not later than 1:00 p.m. on the date of the
requested US Bid Borrowing. Upon satisfaction of the applicable conditions set
forth

                                                          DEVON CREDIT AGREEMENT

                                       40
<PAGE>

in Section 6.02, the Administrative Agent shall make all funds so received
available to the US Borrower in like funds as received by the Administrative
Agent.

         (j)      Notice of Range of US Bids. After each US Competitive Bid
auction pursuant to this Section 2.03, the Administrative Agent shall notify
each Lender that submitted a US Competitive Bid in such auction of the ranges of
bids submitted (without the bidder's name) and accepted for each US Bid Loan and
the aggregate amount of each US Bid Borrowing.

         2.04     US LETTERS OF CREDIT.

         (a)      The US Letter of Credit Commitment.

                  (i)      Subject to the terms and conditions set forth herein,
         (A) the US L/C Issuer agrees, in reliance upon the agreements of the
         other Lenders set forth in this Section 2.04, (1) from time to time on

         Letter of Credit Expiration Date, to issue US Letters of Credit for the

         previously issued by it, in accordance with subsection (b) below, and
         (2) to honor drawings under the US Letters of Credit; and (B) the
         Lenders severally agree to participate in US Letters of Credit issued
         for the account of the US Borrower and any drawings thereunder;
         provided that after giving effect to any US L/C Credit Extension with

         not exceed the Aggregate US Commitments, (y) the aggregate Outstanding
         Amount of the US Committed Loans of any Lender, plus such Lender's Pro
         Rata Share of the Outstanding Amount of all US L/C Obligations, plus
         such Lender's Pro Rata Share of the Outstanding Amount of all US Swing
         Line Loans shall not exceed such Lender's US Commitment, and (z) the
         Outstanding Amount of the US L/C Obligations shall not exceed the US
         Letter of Credit Sublimit. Each request by the US Borrower for the
         issuance or amendment of a US Letter of Credit shall be deemed to be a
         representation by the US Borrower that the US L/C Credit Extension so
         requested complies with the conditions set forth in the proviso to the
         preceding sentence. Within the foregoing limits, and subject to the
         terms and conditions hereof, the US Borrower's ability to obtain US
         Letters of Credit shall be fully revolving, and accordingly the US
         Borrower may, during the foregoing period, obtain US Letters of Credit
         to replace US Letters of Credit that have expired or that have been
         drawn upon and reimbursed. All Existing US Letters of Credit shall be
         deemed to have been issued pursuant hereto, and from and after the
         Closing Date shall be subject to and governed by the terms and
         conditions hereof.

                  (ii)     The US L/C Issuer shall not issue any US Letter of
         Credit, if the expiry date of such requested US Letter of Credit would
         occur after the Letter of Credit Expiration Date, unless all the
         Lenders have approved such expiry date.

                  (iii)    The US L/C Issuer shall not be under any obligation
         to issue any US Letter of Credit if:

                           (A)      any order, judgment or decree of any
                  Governmental Authority or arbitrator shall by its terms
                  purport to enjoin or restrain the US L/C Issuer from issuing
                  such US Letter of Credit, or any Law applicable to the US L/C
                  Issuer or any request or directive (whether or not having the
                  force of law) from any Governmental Authority with
                  jurisdiction over the US L/C Issuer shall prohibit, or request
                  that the US L/C Issuer refrain from, the issuance of letters
                  of credit generally or such US Letter of Credit in particular
                  or shall impose upon the US L/C Issuer with respect to such US
                  Letter of Credit any restriction, reserve or capital
                  requirement (for which the US L/C Issuer is not otherwise
                  compensated hereunder) not in effect on the Closing Date, or
                  shall impose upon the US L/C Issuer any unreimbursed loss,
                  cost or expense which was not applicable on the Closing Date
                  and which the US L/C Issuer in good faith deems material to
                  it, unless the US Borrower confirms that it will pay the
                  foregoing;

                           (B)      the issuance of such US Letter of Credit
                  would violate any Laws;

                           (C)      except as otherwise agreed by the
                  Administrative Agent and the US L/C Issuer, such US Letter of
                  Credit is in an initial face amount less than US $10,000;

                           (D)      such US Letter of Credit is to be
                  denominated in a currency other than US Dollars; or

                           (E)      if the US L/C Issuer is JPMorgan, if such US
                  Letter of Credit is to be issued after the Closing Date unless
                  such US Letter of Credit renews, amends or replaces a US
                  Letter of Credit previously issued by JPMorgan or one of its
                  Affiliates.

                  (iv)     The US L/C Issuer shall not amend any US Letter of
         Credit if the US L/C Issuer would not be permitted at such time to
         issue such US Letter of Credit in its amended form under the terms
         hereof.

                  (v)      The US L/C Issuer shall be under no obligation to
         amend any US Letter of Credit if (A) the US L/C Issuer would have no
         obligation at such time to issue such US Letter of Credit in its
         amended form under the terms hereof, or (B) the beneficiary of such US
         Letter of Credit does not accept the proposed amendment to such US
         Letter of Credit.

         (b)      Procedures for Issuance and Amendment of US Letters of Credit.

                  (i)      Each US Letter of Credit shall be issued or amended,
         as the case may be, upon the request of the US Borrower delivered to
         the US L/C Issuer (with a copy to the Administrative Agent) in the form
         of a US Letter of Credit Application, appropriately completed and
         signed by a Responsible Officer of the US Borrower. Such US Letter of
         Credit Application must be received by the US L/C Issuer and the
         Administrative Agent not later than 11:00 a.m. at least two Business
         Days (or such later date and time as the

                                                          DEVON CREDIT AGREEMENT

         Administrative Agent and the US L/C Issuer may agree in a particular
         instance in their sole discretion) prior to the proposed issuance date
         or date of amendment, as the case may be. In the case of a request for
         an initial issuance of a US Letter of Credit, such US Letter of Credit
         Application shall specify in form and detail satisfactory to the US L/C
         Issuer: (A) the proposed issuance date of the requested US Letter of
         Credit (which shall be a Business Day); (B) the amount thereof; (C) the
         expiry date thereof; (D) the name and address of the beneficiary
         thereof; (E) the documents to be presented by such beneficiary in case
         of any drawing thereunder; (F) the full text of any certificate to be
         presented by such beneficiary in case of any drawing thereunder; and
         (G) such other matters as the US L/C Issuer may reasonably require. In
         the case of a request for an amendment of any outstanding US Letter of
         Credit, such US Letter of Credit Application shall specify in form and
         detail satisfactory to the US L/C Issuer (A) the US Letter of Credit to
         be amended; (B) the proposed date of amendment thereof (which shall be
         a Business Day); (C) the nature of the proposed amendment; and (D) such
         other matters as the US L/C Issuer may require. Additionally, the US
         Borrower shall furnish to the US L/C Issuer and the Administrative
         Agent such other documents and information pertaining to such requested
         US Letter of Credit issuance or amendment, including any Issuer
         Documents, as the US L/C Issuer or the Administrative Agent may
         reasonably require.

                  (ii)     Promptly after receipt of any US Letter of Credit
         Application, the US L/C Issuer will confirm with the Administrative
         Agent (by telephone or in writing) that the Administrative Agent has
         received a copy of such US Letter of Credit Application from the US
         Borrower and, if not, the US L/C Issuer will provide the Administrative
         Agent with a copy thereof. Unless the US L/C Issuer has received
         written notice from any Lender, the Administrative Agent or any Loan
         Party, at least one Business Day prior to the requested date of
         issuance or amendment of the applicable US Letter of Credit, that one
         or more applicable conditions contained in Article VI shall not then be
         satisfied, then, subject to the terms and conditions hereof, the US L/C
         Issuer shall, on the requested date, issue a US Letter of Credit for
         the account of the US Borrower or enter into the applicable amendment,
         as the case may be, in each case in accordance with the US L/C Issuer's
         usual and customary business practices. Immediately upon the issuance
         of each US Letter of Credit, each Lender shall be deemed to, and hereby
         irrevocably and unconditionally agrees to, purchase from the US L/C
         Issuer a risk participation in such US Letter of Credit in an amount
         equal to the product of such Lender's Pro Rata Share times the amount
         of such US Letter of Credit.

                  (iii)    Promptly after its delivery of any US Letter of
         Credit or any amendment to a US Letter of Credit to an advising bank
         with respect thereto or to the beneficiary thereof, the US L/C Issuer
         will also deliver to the US Borrower and the Administrative Agent a
         true and complete copy of such US Letter of Credit or amendment.

         (c)      Drawings and Reimbursements; Funding of Participations.

                  (i)      Upon receipt from the beneficiary of any US Letter of
         Credit of any notice of a drawing under such US Letter of Credit, the
         US L/C Issuer shall notify the US Borrower and the Administrative Agent
         thereof. Not later than 11:00 a.m. on the date of

                                                          DEVON CREDIT AGREEMENT

                                       43
<PAGE>

         any payment by the US L/C Issuer under a US Letter of Credit (each such
         date, an "US Honor Date"), the US Borrower shall reimburse the US L/C
         Issuer through the Administrative Agent in an amount equal to the
         amount of such drawing by means of a Borrowing of US Base Rate
         Committed Loans or otherwise. If the US Borrower fails so to reimburse
         the US L/C Issuer by such time, the Administrative Agent shall promptly
         notify each Lender of the US Honor Date, the amount of the unreimbursed
         drawing (the "US Unreimbursed Amount"), and the amount of such Lender's
         Pro Rata Share thereof. In such event, the US Borrower shall be deemed
         to have requested a US Committed Borrowing of US Base Rate Loans to be
         disbursed on the US Honor Date in an amount equal to the US
         Unreimbursed Amount, without regard to the minimum and multiples
         specified in Section 2.02 for the principal amount of US Base Rate
         Loans, but subject to the amount of the unutilized portion of the
         Aggregate US Commitments and whether or not the conditions set forth in
         Section 6.02 are satisfied. Any notice given by the US L/C Issuer or
         the Administrative Agent pursuant to this Section 2.04(c)(i) may be
         given by telephone if immediately confirmed in writing; provided that
         the lack of such an immediate confirmation shall not affect the
         conclusiveness or binding effect of such notice.

                  (ii)     Each Lender (including the Lender acting as US L/C
         Issuer) shall upon any notice pursuant to Section 2.04(c)(i) make funds
         available to the Administrative Agent for the account of the US L/C
         Issuer at the Administrative Agent's Office in an amount equal to its
         Pro Rata Share of the US Unreimbursed Amount not later than 1:00 p.m.
         on the Business Day specified in such notice by the Administrative
         Agent, whereupon, subject to the provisions of Section 2.04(c)(iii),
         each Lender that so makes funds available shall be deemed to have made
         a US Base Rate Committed Loan to the US Borrower in such amount. The
         Administrative Agent shall remit the funds so received to the US L/C
         Issuer.

                  (iii)    With respect to any US Unreimbursed Amount that is
         not fully refinanced by a US Committed Borrowing of US Base Rate Loans
         for any reason, the US Borrower shall be deemed to have incurred from
         the US L/C Issuer a US L/C Borrowing in the amount of the US
         Unreimbursed Amount that is not so refinanced, which US L/C Borrowing
         shall be due and payable on demand (together with interest) and shall
         bear interest at a per annum rate equal to (i) for the first three (3)
         Business Days after the date of such US L/C Borrowing, the US Base
         Rate, and (ii) thereafter, the US Base Rate plus two percent (2%). In
         such event, each Lender's payment to the Administrative Agent for the
         account of the US L/C Issuer pursuant to Section 2.04(c)(ii) shall be
         deemed payment in respect of its participation in such US L/C Borrowing
         and shall constitute a US L/C Advance from such Lender in satisfaction
         of its participation obligation under this Section 2.04.

                  (iv)     Until each Lender funds its US Committed Loan or US
         L/C Advance pursuant to this Section 2.04(c) to reimburse the US L/C
         Issuer for any amount drawn under any US Letter of Credit, interest in
         respect of such Lender's Pro Rata Share of such amount shall be solely
         for the account of the US L/C Issuer.

<PAGE>

                  (v)      Each Lender's obligation to make US Committed Loans
         or US L/C Advances to reimburse the US L/C Issuer for amounts drawn
         under US Letters of Credit, as contemplated by this Section 2.04(c),
         shall be absolute and unconditional and shall not be affected by any
         circumstance, including (A) any set-off, counterclaim, recoupment,
         defense or other right which such Lender may have against the US L/C
         Issuer, the US Borrower or any other Person for any reason whatsoever;
         (B) the occurrence or continuance of a Default, or (C) any other
         occurrence, event or condition, whether or not similar to any of the
         foregoing. No such making of a US L/C Advance shall relieve or
         otherwise impair the obligation of the US Borrower to reimburse the US
         L/C Issuer for the amount of any payment made by the US L/C Issuer
         under any US Letter of Credit, together with interest as provided
         herein.

                  (vi)     If any Lender fails to make available to the
         Administrative Agent for the account of the US L/C Issuer any amount
         required to be paid by such Lender pursuant to the foregoing provisions
         of this Section 2.04(c) by the time specified in Section 2.04(c)(ii),
         the US L/C Issuer shall be entitled to recover from such Lender (acting
         through the Administrative Agent), on demand, such amount with interest
         thereon for the period from the date such payment is required to the
         date on which such payment is immediately available to the US L/C
         Issuer at a rate per annum equal to the Federal Funds Rate from time to
         time in effect. A certificate of the US L/C Issuer submitted to any
         Lender (through the Administrative Agent) with respect to any amounts
         owing under this clause (vi) shall be conclusive absent manifest error.

         (d)      Repayment of Participations.

                  (i)      At any time after the US L/C Issuer has made a
         payment under any US Letter of Credit and has received from any Lender
         such Lender's US L/C Advance in respect of such payment in accordance
         with Section 2.04(c), if the Administrative Agent receives for the
         account of the US L/C Issuer any payment in respect of the related US
         Unreimbursed Amount or interest thereon (whether directly from the US
         Borrower or otherwise, including proceeds of cash collateral applied
         thereto by the Administrative Agent), the Administrative Agent will
         distribute to such Lender its Pro Rata Share thereof (appropriately
         adjusted, in the case of interest payments, to reflect the period of
         time during which such Lender's US L/C Advance was outstanding) in the
         same funds as those received by the Administrative Agent.

                  (ii)     If any payment received by the Administrative Agent
         for the account of the US L/C Issuer pursuant to Section 2.04(c)(i) is
         required to be returned under any of the circumstances described in
         Section 12.07 (including pursuant to any settlement entered into by the
         US L/C Issuer in its discretion), each Lender shall pay to the
         Administrative Agent for the account of the US L/C Issuer its Pro Rata
         Share thereof on demand of the Administrative Agent, plus interest
         thereon from the date of such demand to the date such amount is
         returned by such Lender, at a rate per annum equal to the Federal Funds
         Rate from time to time in effect.

<PAGE>

         (e)      Obligations Absolute. The obligation of the US Borrower to
reimburse the US L/C Issuer for each drawing under each US Letter of Credit and
to repay each US L/C Borrowing shall be absolute, unconditional and irrevocable,
and shall be paid strictly in accordance with the terms of this Agreement under
all circumstances, including the following:

                  (i)      any lack of validity or enforceability of such US
         Letter of Credit, this Agreement, or any other Loan Document;

                  (ii)     the existence of any claim, counterclaim, set-off,
         defense or other right that the US Borrower or any Subsidiary may have
         at any time against any beneficiary or any transferee of such US Letter
         of Credit (or any Person for whom any such beneficiary or any such
         transferee may be acting), the US L/C Issuer or any other Person,
         whether in connection with this Agreement, the transactions
         contemplated hereby or by such US Letter of Credit or any agreement or
         instrument relating thereto, or any unrelated transaction;

                  (iii)    any draft, demand, certificate or other document
         presented under such US Letter of Credit proving to be forged,
         fraudulent, invalid or insufficient in any respect or any statement
         therein being untrue or inaccurate in any respect; or any loss or delay
         in the transmission or otherwise of any document required in order to
         make a drawing under such US Letter of Credit;

                  (iv)     any payment by the US L/C Issuer under such US Letter
         of Credit against presentation of a draft or certificate that does not
         strictly comply with the terms of such US Letter of Credit; or any
         payment made by the US L/C Issuer under such US Letter of Credit to any
         Person purporting to be a trustee in bankruptcy, debtor-in-possession,
         assignee for the benefit of creditors, liquidator, receiver or other
         representative of or successor to any beneficiary or any transferee of
         such US Letter of Credit, including any arising in connection with any
         proceeding under any Debtor Relief Law; or

                  (v)      any other circumstance or happening whatsoever,
         whether or not similar to any of the foregoing, including any other
         circumstance that might otherwise constitute a defense available to, or
         a discharge of, the US Borrower or any Subsidiary.

         The US Borrower shall promptly examine a copy of each US Letter of
Credit and each amendment thereto that is delivered to it and, in the event of
any claim of noncompliance with the US Borrower's instructions or other
irregularity, the US Borrower will promptly notify the US L/C Issuer. The US
Borrower shall be conclusively deemed to have waived any such claim against the
US L/C Issuer and its correspondents unless such notice is given as aforesaid.

         (f)      Role of US L/C Issuer. Each Lender and the US Borrower agree
that, in paying any drawing under a US Letter of Credit, the US L/C Issuer shall
not have any responsibility to obtain any document (other than any sight draft,
certificates and documents expressly required by the US Letter of Credit) or to
ascertain or inquire as to the validity or accuracy of any such document or the
authority of the Person executing or delivering any such document. None of the
US L/C Issuer, any Agent-Related Person nor any of the respective
correspondents, participants

                                       46
<PAGE>

or assignees of the US L/C Issuer shall be liable to any Lender for (i) any
action taken or omitted in connection herewith at the request or with the
approval of the Lenders or the US Required Lenders, as applicable; (ii) any
action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any document or instrument related to any US Letter of Credit
or US Letter of Credit Application. The US Borrower hereby assumes all risks of
the acts or omissions of any beneficiary or transferee with respect to its use
of any US Letter of Credit; provided, however, that this assumption is not
intended to, and shall not, preclude the US Borrower's pursuing such rights and
remedies as it may have against the beneficiary or transferee at law or under
any other agreement. None of the US L/C Issuer, any Agent-Related Person, nor
any of the respective correspondents, participants or assignees of the US L/C
Issuer, shall be liable or responsible for any of the matters described in
clauses (i) through (v) of Section 2.04(e); provided, however, that anything in
such clauses to the contrary notwithstanding, the US Borrower may have a claim
against the US L/C Issuer, and the US L/C Issuer may be liable to the US
Borrower, to the extent, but only to the extent, of any direct, as opposed to
consequential or exemplary, damages suffered by the US Borrower which the US
Borrower proves were caused by the US L/C Issuer's willful misconduct or gross
negligence or the US L/C Issuer's willful failure to pay under any US Letter of
Credit after the presentation to it by the beneficiary of a sight draft and
certificate(s) strictly complying with the terms and conditions of a US Letter
of Credit. In furtherance and not in limitation of the foregoing, the US L/C
Issuer may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary, and the US L/C Issuer shall not be responsible for
the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a US Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

         (g)      Cash Collateral. Upon the request of the Administrative Agent,
(i) if the US L/C Issuer has honored any full or partial drawing request under
any US Letter of Credit and such drawing has resulted in a US L/C Borrowing, or
(ii) if, as of the Letter of Credit Expiration Date, any US Letter of Credit for
any reason remains outstanding and partially or wholly undrawn, the US Borrower
shall immediately Cash Collateralize the then Outstanding Amount of all US L/C
Obligations (in an amount equal to such Outstanding Amount determined as of the
date of such US L/C Borrowing or the Letter of Credit Expiration Date, as the
case may be). Sections 3.06 and 10.02(c) set forth certain additional
requirements to deliver Cash Collateral hereunder. The US Borrower hereby grants
to the Administrative Agent, for the benefit of the US L/C Issuer and the
Lenders, a security interest in all such cash, deposit accounts and all balances
therein and all proceeds of the foregoing. Such Cash Collateral shall be
maintained in blocked deposit accounts at Bank of America. Pending application
thereof, such Cash Collateral shall be invested by the US L/C Issuer in such
investments as the applicable US L/C Issuer may choose in its sole discretion.
All interest on (and other proceeds of) such investments shall be reinvested or
applied to US L/C Obligations or other US Obligations which are due and payable.

         (h)      Applicability of ISP98 and UCP. Unless otherwise expressly
agreed by the US L/C Issuer and the US Borrower when a US Letter of Credit is
issued (including any such agreement applicable to an Existing US Letter of
Credit), (i) the rules of the ISP shall apply to each standby US Letter of
Credit, and (ii) the rules of the Uniform Customs and Practice for

                                                          DEVON CREDIT AGREEMENT

                                       47
<PAGE>

Documentary Credits, as most recently published by the International Chamber of
Commerce at the time of issuance shall apply to each commercial US Letter of
Credit.

         (i)      US Letter of Credit Fees. The US Borrower shall pay to the
Administrative Agent for the account of each Lender in accordance with its Pro
Rata Share a US Letter of Credit fee (the "US Letter of Credit Fee") for each US
Letter of Credit equal to the Applicable Rate times the daily maximum amount
available to be drawn under such US Letter of Credit. US Letter of Credit Fees
shall be (i) computed on a quarterly basis in arrears and (ii) due and payable
on the first Business Day after the end of each March, June, September and
December, commencing with the first such date to occur after the issuance of
such US Letter of Credit, on the Letter of Credit Expiration Date and thereafter
on demand. If there is any change in the Applicable Rate during any quarter, the
daily maximum amount of each standby US Letter of Credit shall be computed and
multiplied by the Applicable Rate separately for each period during such quarter
that such Applicable Rate was in effect.

         (j)      Fronting Fee and Documentary and Processing Charges Payable to
US L/C Issuer. The US Borrower shall pay directly to the US L/C Issuer for its
own account a fronting fee with respect to each US Letter of Credit in the
amount specified in the applicable Fee Letter, payable on the actual daily
maximum amount available to be drawn under such US Letter of Credit. Such
fronting fee shall be computed on a quarterly basis in arrears. Such fronting
fee shall be due and payable on the first Business Day after the end of each
March, June, September and December, commencing with the first such date to
occur after the issuance of such US Letter of Credit, on the Letter of Credit
Expiration Date and thereafter on demand. In addition, the US Borrower shall pay
directly to the US L/C Issuer for its own account the customary issuance,
presentation, amendment and other processing fees, and other standard costs and
charges, of the US L/C Issuer relating to letters of credit as agreed to by the
US Borrower and the applicable US L/C Issuer. Such customary fees and standard
costs and charges are due and payable on demand and are nonrefundable.

         (k)      Conflict with Issuer Documents. In the event of any conflict
between the terms hereof and the terms of any Issuer Document, the terms hereof
shall control.

         (l)      Designation of Subsidiaries as Account Parties.
Notwithstanding anything to the contrary set forth in this Agreement, including
without limitation Section 2.04(a), a US Letter of Credit issued hereunder
shall, upon the request of the US Borrower, be issued for the account of any
Subsidiary of the US Borrower, provided that notwithstanding such request, the
US Borrower shall be the actual account party for all purposes of this Agreement
for such US Letter of Credit, and such request shall not affect the US
Borrower's reimbursement obligations hereunder with respect to such US Letter of
Credit.

         2.05     US SWING LINE LOANS.

         (a)      The US Swing Line. Subject to the terms and conditions set
forth herein, the US Swing Line Lender agrees to make loans (each such loan, a
"US Swing Line Loan") to the US Borrower from time to time on any Business Day
during the Availability Period in an aggregate amount not to exceed at any time
outstanding the amount of the US Swing Line Sublimit,

                                                          DEVON CREDIT AGREEMENT

                                       48
<PAGE>

notwithstanding the fact that such US Swing Line Loans, when aggregated with the
Pro Rata Share of the Outstanding Amount of US Committed Loans and US L/C
Obligations of the Lender acting as US Swing Line Lender, may exceed the amount
of such Lender's US Commitment; provided, however, that after giving effect to
any US Swing Line Loan, (i) the Total US Outstandings shall not exceed the
Aggregate US Commitments, and (ii) the aggregate Outstanding Amount of the US
Committed Loans of any Lender, plus such Lender's Pro Rata Share of the
Outstanding Amount of all US L/C Obligations, plus such Lender's Pro Rata Share
of the Outstanding Amount of all US Swing Line Loans shall not exceed such
Lender's US Commitment, and provided, further, that the US Borrower shall not
use the proceeds of any US Swing Line Loan to refinance any outstanding US Swing
Line Loan. Within the foregoing limits, and subject to the other terms and
conditions hereof, the US Borrower may borrow under this Section 2.05, prepay
under Section 2.06, and reborrow under this Section 2.05. Each US Swing Line
Loan shall be a US Base Rate Loan. Immediately upon the making of a US Swing
Line Loan, each Lender shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the US Swing Line Lender a risk
participation in such US Swing Line Loan in an amount equal to the product of
such Lender's Pro Rata Share times the amount of such US Swing Line Loan.

         (b)      US Borrowing Procedures. Each US Swing Line Borrowing shall be
made upon the US Borrower's irrevocable notice to the US Swing Line Lender and
the Administrative Agent, which may be given by telephone. Each such notice must
be received by the US Swing Line Lender and the Administrative Agent not later
than 3:00 p.m. on the requested borrowing date, and shall specify (i) the amount
to be borrowed, which shall be a minimum of US $1,000,000, and (ii) the
requested borrowing date, which shall be a Business Day. Each such telephonic
notice must be confirmed promptly by delivery to the US Swing Line Lender and
the Administrative Agent of a written US Swing Line Loan Notice, appropriately
completed and signed by a Responsible Officer of the US Borrower. Promptly after
receipt by the US Swing Line Lender of any telephonic US Swing Line Loan Notice,
the US Swing Line Lender will confirm with the Administrative Agent (by
telephone or in writing) that the Administrative Agent has also received such US
Swing Line Loan Notice and, if not, the US Swing Line Lender will notify the
Administrative Agent (by telephone or in writing) of the contents thereof.
Unless the US Swing Line Lender has received notice (by telephone or in writing)
from the Administrative Agent (including at the request of any Lender) prior to
4:00 p.m. on the date of the proposed US Swing Line Borrowing (A) directing the
US Swing Line Lender not to make such US Swing Line Loan as a result of the
limitations set forth in the proviso to the first sentence of Section 2.05(a),
or (B) that one or more of the applicable conditions specified in Article VI is
not then satisfied, then, subject to the terms and conditions hereof, the US
Swing Line Lender will, not later than 5:00 p.m. on the borrowing date specified
in such US Swing Line Loan Notice, make the amount of its US Swing Line Loan
available to the US Borrower at its office by crediting the account of the US
Borrower on the books of the US Swing Line Lender in immediately available
funds.

         (c)      Refinancing of US Swing Line Loans.

                  (i)      The US Swing Line Lender at any time in its sole and
         absolute discretion may request, on behalf of the US Borrower (which
         hereby irrevocably authorizes the US

                                                          DEVON CREDIT AGREEMENT

                                       49
<PAGE>

         Swing Line Lender to so request on its behalf), that each Lender make a
         US Base Rate Committed Loan in an amount equal to such Lender's Pro
         Rata Share of the amount of US Swing Line Loans then outstanding. Such
         request shall be made in writing (which written request shall be deemed
         to be a US Committed Loan Notice for purposes hereof) and in accordance
         with the requirements of Section 2.02, without regard to the minimum
         and multiples specified therein for the principal amount of US Base
         Rate Loans, but subject to the unutilized portion of the Aggregate US
         Commitments and the conditions set forth in Section 6.02. The US Swing
         Line Lender shall furnish the US Borrower with a copy of the applicable
         US Committed Loan Notice promptly after delivering such notice to the
         Administrative Agent. Each Lender shall make an amount equal to its Pro
         Rata Share of the amount specified in such US Committed Loan Notice
         available to the Administrative Agent in immediately available funds
         for the account of the US Swing Line Lender at the Administrative
         Agent's Office not later than 1:00 p.m. on the day specified in such US
         Committed Loan Notice, whereupon, subject to Section 2.05(c)(ii), each
         Lender that so makes funds available shall be deemed to have made a US
         Base Rate Committed Loan to the US Borrower in such amount. The
         Administrative Agent shall remit the funds so received to the US Swing
         Line Lender.

                  (ii)     If for any reason any US Swing Line Loan cannot be
         refinanced by such a US Committed Borrowing in accordance with Section
         2.05(c)(i), the request for US Base Rate Committed Loans submitted by
         the US Swing Line Lender as set forth herein shall be deemed to be a
         request by the US Swing Line Lender that each of the Lenders fund its
         risk participation in the relevant US Swing Line Loan and each Lender's
         payment to the Administrative Agent for the account of the US Swing
         Line Lender pursuant to Section 2.05(c)(i) shall be deemed payment in
         respect of such participation.

                  (iii)    If any Lender fails to make available to the
         Administrative Agent for the account of the US Swing Line Lender any
         amount required to be paid by such Lender pursuant to the foregoing
         provisions of this Section 2.05(c) by the time specified in Section
         2.05(c)(i), the US Swing Line Lender shall be entitled to recover from
         such Lender (acting through the Administrative Agent), on demand, such
         amount with interest thereon for the period from the date such payment
         is required to the date on which such payment is immediately available
         to the US Swing Line Lender at a rate per annum equal to the Federal
         Funds Rate from time to time in effect. A certificate of the US Swing
         Line Lender submitted to any Lender (through the Administrative Agent)
         with respect to any amounts owing under this clause (iii) shall be
         conclusive absent manifest error.

                  (iv)     Each Lender's obligation to make US Committed Loans
         or to purchase and fund risk participations in US Swing Line Loans
         pursuant to this Section 2.05(c) shall be absolute and unconditional
         and shall not be affected by any circumstance, including (A) any
         set-off, counterclaim, recoupment, defense or other right which such
         Lender may have against the US Swing Line Lender, the US Borrower or
         any other Person for any reason whatsoever, (B) the occurrence or
         continuance of a Default, or (C) any other occurrence, event or
         condition, whether or not similar to any of the foregoing; provided,
         however, that each Lender's obligation to make US Committed Loans
         pursuant to this Section 2.05(c) is subject to the conditions set forth
         in Section 6.02. No such

                                                          DEVON CREDIT AGREEMENT

                                       50
<PAGE>

         funding of risk participations shall relieve or otherwise impair the
         obligation of the US Borrower to repay US Swing Line Loans, together
         with interest as provided herein.

         (d)      Repayment of Participations.

                  (i)      At any time after any Lender has purchased and funded
         a risk participation in a US Swing Line Loan, if the US Swing Line
         Lender receives any payment on account of such US Swing Line Loan, the
         US Swing Line Lender will distribute to such Lender its Pro Rata Share
         of such payment (appropriately adjusted, in the case of interest
         payments, to reflect the period of time during which such Lender's risk
         participation was funded) in the same funds as those received by the US
         Swing Line Lender.

                  (ii)     If any payment received by the US Swing Line Lender
         in respect of principal or interest on any US Swing Line Loan is
         required to be returned by the US Swing Line Lender under any of the
         circumstances described in Section 12.07 (including pursuant to any
         settlement entered into by the US Swing Line Lender in its discretion),
         each Lender shall pay to the US Swing Line Lender its Pro Rata Share
         thereof on demand of the Administrative Agent, plus interest thereon
         from the date of such demand to the date such amount is returned, at a
         rate per annum equal to the Federal Funds Rate. The Administrative
         Agent will make such demand upon the request of the US Swing Line
         Lender.

         (e)      Interest for Account of US Swing Line Lender. The US Swing
Line Lender shall be responsible for invoicing the US Borrower for interest on
the US Swing Line Loans. Until each Lender funds its US Base Rate Committed Loan
or risk participation pursuant to this Section 2.05 to refinance such Lender's
Pro Rata Share of any US Swing Line Loan, interest in respect of such Pro Rata
Share shall be solely for the account of the US Swing Line Lender.

         (f)      Payments Directly to US Swing Line Lender. The US Borrower
shall make all payments of principal and interest in respect of the US Swing
Line Loans directly to the US Swing Line Lender.

         2.06     PREPAYMENTS.

         (a)      The US Borrower may, upon notice to the Administrative Agent,
at any time or from time to time voluntarily prepay US Committed Loans in whole
or in part without premium or penalty; provided that (i) such notice must be
received by the Administrative Agent not later than 11:00 a.m. (A) two Business
Days prior to any date of prepayment of US Eurodollar Rate Committed Loans and
(B) on the date of prepayment of US Base Rate Committed Loans; (ii) any
prepayment of US Eurodollar Rate Committed Loans shall be in a principal amount
of US $5,000,000 or a whole multiple of US $1,000,000 in excess thereof; and
(iii) any prepayment of US Base Rate Committed Loans shall be in a principal
amount of US $1,000,000 or a whole multiple of US $100,000 in excess thereof or,
in each case, if less, the entire principal amount thereof then outstanding.
Each such notice shall specify the date and amount of such prepayment and the
Type(s) of US Committed Loans to be prepaid. The Administrative Agent will
promptly notify each Lender of its receipt of each such notice, and of the
amount of such Lender's Pro

                                                          DEVON CREDIT AGREEMENT

                                       51
<PAGE>

Rata Share of such prepayment. If such notice is given by the US Borrower, the
US Borrower shall make such prepayment and the payment amount specified in such
notice shall be due and payable on the date specified therein. Any prepayment of
a US Dollar Eurodollar Rate Loan shall be accompanied by all accrued interest
thereon, together with any additional amounts required pursuant to Section 5.05.
Each such prepayment shall be applied to the US Committed Loans of the Lenders
in accordance with their respective Pro Rata Shares.

         (b)      No US Bid Loan may be prepaid without the prior consent of the
applicable US Bid Loan Lender.

         (c)      The US Borrower may, upon notice to the US Swing Line Lender
(with a copy to the Administrative Agent), at any time or from time to time,
voluntarily prepay US Swing Line Loans in whole or in part without premium or
penalty; provided that (i) such notice must be received by the US Swing Line
Lender and the Administrative Agent not later than 1:00 p.m. on the date of the
prepayment, and (ii) any such prepayment shall be in a minimum principal amount
of US $1,000,000. Each such notice shall specify the date and amount of such
prepayment. If such notice is given by the US Borrower, the US Borrower shall
make such prepayment and the payment amount specified in such notice shall be
due and payable on the date specified therein.

         (d)      If for any reason the Total US Outstandings at any time exceed
the Aggregate US Commitments then in effect, the US Borrower shall immediately
prepay Loans and/or Cash Collateralize the US L/C Obligations in an aggregate
amount equal to such excess; provided, however, that the US Borrower shall not
be required to Cash Collateralize the US L/C Obligations pursuant to this
Section 2.06(d) unless after the prepayment in full of the US Committed Loans
and US Swing Line Loans the Total US Outstandings exceed the Aggregate US
Commitments then in effect.

         2.07     REPAYMENT OF US LOANS.

         (a)      The US Borrower shall repay to each Lender on the Maturity
Date the aggregate principal amount of its US Committed Loans and all other US
Obligations owing to such Lender outstanding on such date.

         (b)      The US Borrower shall repay each US Bid Loan on the last day
of the Interest Period in respect thereof.

                                  ARTICLE III.
                              CANADIAN SUBFACILITY

         3.01     CANADIAN COMMITTED LOANS. Subject to the terms and conditions
set forth herein, each Canadian Lender severally agrees to make loans (each such
loan, a "Canadian Committed Loan") to each Canadian Borrower from time to time,
on any Business Day during the Availability Period, in an aggregate amount not
to exceed at any time outstanding the amount of the Canadian Commitment of such
Canadian Lender; provided, however, that after giving effect to any Canadian
Committed Borrowing, (i) the Total Canadian Outstandings (calculated,

                                                          DEVON CREDIT AGREEMENT

                                       52
<PAGE>

as necessary, at the US Dollar Equivalent thereof) shall not exceed the
Aggregate Canadian Commitments, and (ii) the aggregate Outstanding Amount of the
Canadian Committed Loans of any Canadian Lender, plus such Canadian Lender's Pro
Rata Share of the Outstanding Amount of all Canadian L/C Obligations, plus such
Canadian Lender's Pro Rata Share of the Outstanding Amount of all Canadian Swing
Line Loans plus such Canadian Lender's Bankers' Acceptances (in each case,
calculated, as necessary, at the US Dollar Equivalent thereof) shall not exceed
the Canadian Commitment of such Canadian Lender. Within the limits of the
Canadian Commitment of each Canadian Lender, and subject to the other terms and
conditions hereof, each Canadian Borrower may borrow under this Section 3.01,
prepay under Section 3.06, and reborrow under this Section 3.01. Canadian
Committed Loans may be Canadian Prime Rate Loans, Canadian Base Rate Committed
Loans, Canadian Dollar Eurodollar Rate Loans or Canadian US Eurodollar Rate
Committed Loans, as further provided herein.

         3.02     CANADIAN BORROWINGS, CONVERSIONS AND CONTINUATIONS OF CANADIAN
COMMITTED LOANS.

         (a)      Each Canadian Committed Borrowing, each conversion of Canadian
Committed Loans from one Type to another, and each continuation of Canadian
Eurodollar Rate Committed Loans or Canadian US Eurodollar Rate Committed Loans
shall be made upon the applicable Canadian Borrower's irrevocable notice to the
Administrative Agent, which may be given by telephone. Each such notice must be
received by the Administrative Agent not later than 11:00 a.m. (i) three
Business Days prior to the requested date of any Canadian Borrowing of,
conversion to or continuation of Canadian Eurodollar Rate Committed Loans or
Canadian US Eurodollar Rate Committed Loans or of any conversion of Canadian
Eurodollar Rate Committed Loans or Canadian US Eurodollar Rate Committed Loans
to Canadian Prime Rate Committed Loans or Canadian Base Rate Committed Loans,
and (ii) on the requested date of any Canadian Borrowing of Canadian Base Rate
Committed Loans or Canadian Prime Rate Committed Loans. Each telephonic notice
by the Canadian Borrower pursuant to this Section 3.02(a) must be confirmed
promptly by delivery to the Administrative Agent of a written Canadian Committed
Borrowing Notice, appropriately completed and signed by a Responsible Officer of
the applicable Canadian Borrower. Each Canadian Borrowing of, conversion to or
continuation of Canadian Eurodollar Rate Committed Loans or Canadian US
Eurodollar Rate Committed Loans shall be in a principal amount of $5,000,000 in
the Applicable Currency or a whole multiple of $1,000,000 of the Applicable
Currency in excess thereof. Except as provided in Sections 3.04(c) and 3.05(c),
each Canadian Borrowing of or conversion to Canadian Base Rate Committed Loans
or Canadian Prime Rate Committed Loans shall be in a principal amount of
$1,000,000 in the Applicable Currency or a whole multiple of $100,000 in the
Applicable Currency in excess thereof. Each Canadian Committed Borrowing Notice
(whether telephonic or written) shall specify (i) whether the applicable
Canadian Borrower is requesting a Canadian Committed Borrowing, a conversion of
Canadian Committed Loans from one Type to another, or a continuation of Canadian
Eurodollar Rate Committed Loans or Canadian US Eurodollar Rate Committed Loans,
(ii) the requested date of the Canadian Borrowing, conversion or continuation,
as the case may be (which shall be a Business Day), (iii) the principal amount
of Canadian Committed Loans to be borrowed, converted or continued, (iv) the
Type of Canadian Committed Loans to be borrowed or to which existing Canadian
Committed Loans are to be converted, and (v) if applicable, the duration of the
Interest Period with respect thereto. If the

                                                          DEVON CREDIT AGREEMENT

                                       53
<PAGE>

Canadian Borrower fails to specify a Type of Canadian Committed Loan in a
Canadian Committed Borrowing Notice or if the applicable Canadian Borrower fails
to give a timely notice requesting a conversion or continuation, then the
applicable Canadian Loans denominated in Canadian Dollars shall be made as, or
converted to, Canadian Prime Rate Committed Loans and the applicable Canadian
Loans denominated in US Dollars shall be made as, or converted to, Canadian Base
Rate Committed Loans. Any such automatic conversion shall be effective as of the
last day of the Interest Period then in effect with respect to the applicable
Canadian Eurodollar Rate Committed Loans or the applicable Canadian US
Eurodollar Rate Committed Loans. If a Canadian Borrower requests a Canadian
Committed Borrowing of, conversion to, or continuation of Canadian Eurodollar
Rate Committed Loans in any such Canadian Committed Borrowing Notice, but fails
to specify an Interest Period, it will be deemed to have specified an Interest
Period of one month.

         (b)      Following receipt of a Canadian Committed Borrowing Notice,
the Administrative Agent shall promptly notify each Canadian Lender of the
amount of its Pro Rata Share of the applicable Canadian Committed Loans, and if
no timely notice of a conversion or continuation is provided by the applicable
Canadian Borrower, the Administrative Agent shall notify each Canadian Lender of
the details of any automatic conversion to Canadian Prime Rate Committed Loans
or Canadian Base Rate Committed Loans described in the preceding subsection. In
the case of a Canadian Committed Borrowing, each Canadian Lender shall make the
amount of its Canadian Committed Loan available to the Administrative Agent in
immediately available funds at the Administrative Agent's Office not later than
1:00 p.m. on the Business Day specified in the applicable Canadian Committed
Borrowing Notice. Upon satisfaction of the applicable conditions set forth in
Section 6.02 (and, if such Canadian Borrowing is the initial Canadian Credit
Extension, Section 6.01), the Administrative Agent shall make all funds so
received available to the applicable Canadian Borrower in like funds as received
by the Administrative Agent either by (i) crediting the account of the
applicable Canadian Borrower on the books of Bank of America, acting through its
Canadian Branch with the amount of such funds or (ii) wire transfer of such
funds, in each case in accordance with instructions provided to (and reasonably
acceptable to) the Administrative Agent by the applicable Canadian Borrower;
provided, however, that if, on the date the Canadian Committed Borrowing Notice
with respect to such Canadian Borrowing is given by the applicable Canadian
Borrower, there are Canadian L/C Borrowings outstanding, then the proceeds of
such Canadian Borrowing, first, shall be applied, to the payment in full of any
such Canadian L/C Borrowings, and second, shall be made available to the
applicable Canadian Borrower as provided above.

         (c)      Except as otherwise provided herein, a Canadian Eurodollar
Rate Committed Loan or a Canadian US Eurodollar Rate Committed Loan may be
continued or converted only on the last day of an Interest Period for such
Committed Loan. During the existence of a Default, no Loans may be requested as,
converted to or continued as Canadian Eurodollar Rate Committed Loans or a
Canadian US Eurodollar Rate Committed Loan without the consent of the Canadian
Required Lenders.

         (d)      The Administrative Agent shall promptly notify the Canadian
Borrowers and the Canadian Lenders of the interest rate applicable to any
Interest Period for a Canadian Eurodollar Rate Committed Loan or a Canadian US
Eurodollar Rate Committed Loan upon determination

of such interest rate. The determination of the Canadian Dollar Eurodollar Rate
or US Dollar Eurodollar Rate by the Administrative Agent shall be conclusive in
the absence of manifest error. At any time that Canadian Prime Rate Loans or
Canadian Base Rate Committed Loans are outstanding, the Administrative Agent
shall notify the Canadian Borrowers and the Canadian Lenders of any change in
the prime rate or base rate used in determining the Canadian Prime Rate Loans or
Canadian Base Rate promptly following the public announcement of such change.

         (e)      After giving effect to all Canadian Committed Borrowings, all
conversions of Canadian Committed Loans from one Type to another, and all
continuations of Canadian Committed Loans as the same Type, there shall not be
more than ten Interest Periods in effect with respect to Canadian Committed
Loans for each Canadian Borrower.

         (f)      Except as otherwise provided herein, a Canadian Bankers'
Acceptance may be rolled over or converted only on its maturity date. During the
existence of a Default, no Canadian Borrowings may be requested as or converted
to, and no Canadian Bankers' Acceptances may be rolled over as new Canadian
Bankers' Acceptances without the consent of Canadian Required Lenders.

         3.03     CANADIAN BID LOANS.

         (a)      General. Subject to the terms and conditions set forth herein,
each Canadian Lender agrees that each Canadian Borrower may from time to time
request the Canadian Lenders to submit offers to make loans (each such loan, a
"Canadian Bid Loan") for requested maturities of thirty (30) days or more to the
Canadian Borrowers prior to the Maturity Date pursuant to this Section 3.03;
provided, however, that after giving effect to any Canadian Bid Borrowing, the
Total Canadian Outstandings shall not exceed the Aggregate Canadian Commitments.
There shall not be more than five different Interest Periods in effect with
respect to Canadian Bid Loans at any time.

         (b)      Requesting Canadian Competitive Bids. A Canadian Borrower may
request the submission of Canadian Competitive Bids by delivering a Canadian Bid
Request to the Administrative Agent not later than 12:00 noon (i) one Business
Day prior to the requested date of any Canadian Bid Borrowing that is to consist
of Canadian Absolute Rate Loans, or (ii) four Business Days prior to the
requested date of any Canadian Bid Borrowing that is to consist of Canadian
Eurodollar Margin Bid Loans. Each Canadian Bid Request shall specify (i) the
requested date of the Canadian Bid Borrowing (which shall be a Business Day),
(ii) the aggregate principal amount of Canadian Bid Loans requested (which must
be C$5,000,000 or a whole multiple of C$1,000,000 in excess thereof), (iii) the
Type of Canadian Bid Loans requested, and (iv) the duration of the Interest
Period with respect thereto, and shall be signed by a Responsible Officer of the
Canadian Borrower. No Canadian Bid Request shall contain a request for (i) more
than one Type of Canadian Bid Loan or (ii) Canadian Bid Loans having more than
three different Interest Periods. Unless the Administrative Agent otherwise
agrees in its sole and absolute discretion, the Canadian Borrowers may not
submit a Canadian Bid Request if it has submitted another Canadian Bid Request
within the prior five Business Days.

         (c)      Submitting Canadian Competitive Bids.

<PAGE>

         (i)      The Administrative Agent shall promptly notify each Canadian
Lender of each Canadian Bid Request received by it from a Canadian Borrower and
the contents of such Canadian Bid Request.

         (ii)     Each Canadian Lender may (but shall have no obligation to)
submit a Canadian Competitive Bid containing an offer to make one or more
Canadian Bid Loans in response to such Canadian Bid Request. Such Canadian
Competitive Bid must be delivered to the Administrative Agent not later than
10:30 a.m. (A) on the requested date of any Canadian Bid Borrowing that is to
consist of Canadian Absolute Rate Loans, and (B) three Business Days prior to
the requested date of any Canadian Bid Borrowing that is to consist of Canadian
Eurodollar Margin Bid Loans; provided, however, that any Canadian Competitive
Bid submitted by Bank of America in its capacity as a Canadian Lender in
response to any Canadian Bid Request must be submitted to the Administrative
Agent not later than 10:15 a.m. on the date on which Canadian Competitive Bids
are required to be delivered by the other Canadian Lenders in response to such
Canadian Bid Request. Each Canadian Competitive Bid shall specify (A) the
proposed date of the Canadian Bid Borrowing; (B) the principal amount of each
Canadian Bid Loan for which such Canadian Competitive Bid is being made, which
principal amount (x) may be equal to, greater than or less than the Canadian
Commitment of the bidding Canadian Lender, (y) must be C$5,000,000 or a whole
multiple of C$1,000,000 in excess thereof, and (z) may not exceed the principal
amount of Canadian Bid Loans for which Canadian Competitive Bids were requested;
(C) if the proposed Canadian Bid Borrowing is to consist of Canadian Absolute
Rate Loans, the Absolute Rate offered for each such Canadian Bid Loan and the
Interest Period applicable thereto; (D) if the proposed Canadian Bid Borrowing
is to consist of Canadian Eurodollar Margin Bid Loans, the Canadian Eurodollar
Bid Margin with respect to each such Canadian Eurodollar Margin Bid Loan and the
Interest Period applicable thereto; and (E) the identity of the bidding Canadian
Lender.

         (iii)    Any Canadian Competitive Bid shall be disregarded if it (A) is
received after the applicable time specified in clause (ii) above, (B) is not
substantially in the form of a Canadian Competitive Bid as specified herein, (C)
contains qualifying, conditional or similar language, (D) proposes terms other
than or in addition to those set forth in the applicable Canadian Bid Request,
or (E) is otherwise not responsive to such Canadian Bid Request. Any Canadian
Lender may correct a Canadian Competitive Bid containing a manifest error by
submitting a corrected Canadian Competitive Bid (identified as such) not later
than the applicable time required for submission of Canadian Competitive Bids.
Any such submission of a corrected Canadian Competitive Bid shall constitute a
revocation of the Canadian Competitive Bid that contained the manifest error.
The Administrative Agent may, but shall not be required to, notify any Canadian
Lender of any manifest error it detects in such Canadian Lender's Canadian
Competitive Bid.

         (iv)     Subject only to the provisions of Sections 5.02, 5.03 and 6.02
and clause (iii) above, each Canadian Competitive Bid shall be irrevocable.

         (d)      Notice to Canadian Borrowers of Canadian Competitive Bids. Not
later than 11:00 a.m. (i) on the requested date of any Canadian Bid Borrowing
that is to consist of Canadian Absolute Rate Loans, or (ii) three Business Days
prior to the requested date of any Canadian Bid Borrowing that is to consist of
Canadian Eurodollar Margin Bid Loans, the Administrative Agent shall notify the
applicable Canadian Borrower of the identity of each Canadian Lender that has
submitted a Canadian Competitive Bid that complies with Section 3.03(c) and of
the terms of the offers contained in each such Canadian Competitive Bid.

         (e)      Acceptance of Canadian Competitive Bids. Not later than 11:30
a.m. (i) on the requested date of any Canadian Bid Borrowing that is to consist
of Canadian Absolute Rate Loans, and (ii) three Business Days prior to the
requested date of any Canadian Bid Borrowing that is to consist of Canadian
Eurodollar Margin Bid Loans, the applicable Canadian Borrower shall notify the
Administrative Agent of its acceptance or rejection of the offers notified to it
pursuant to Section 3.03(d). The applicable Canadian Borrower shall be under no
obligation to accept any Canadian Competitive Bid and may choose to reject all
Canadian Competitive Bids. In the case of acceptance, such notice shall specify
the aggregate principal amount of Canadian Competitive Bids for each Interest
Period that is accepted. The applicable Canadian Borrower may accept any
Canadian Competitive Bid in whole or in part; provided that:

                  (i)      the aggregate principal amount of each Canadian Bid
         Borrowing may not exceed the applicable amount set forth in the related
         Canadian Bid Request;

                  (ii)     the principal amount of each Canadian Bid Loan must
         be C$5,000,000 or a whole multiple of C$1,000,000 in excess thereof;

                  (iii)    the acceptance of offers may be made only on the
         basis of ascending Absolute Rates or Canadian Eurodollar Bid Margins
         within each Interest Period; and

                  (iv)     the Canadian Borrower may not accept any offer that
         is described in Section 3.03(c)(iii) or that otherwise fails to comply
         with the requirements hereof.

         (f)      Procedure for Identical Canadian Bids. If two or more Canadian
Lenders have submitted Canadian Competitive Bids at the same Absolute Rate or
Canadian Eurodollar Bid Margin, as the case may be, for the same Interest
Period, and the result of accepting all of such Canadian Competitive Bids in
whole (together with any other Canadian Competitive Bids at lower Absolute Rates
or Canadian Eurodollar Bid Margins, as the case may be, accepted for such
Interest Period in conformity with the requirements of Section 3.03(e)(iii))
would be to cause the aggregate outstanding principal amount of the applicable
Canadian Bid Borrowing to exceed the amount specified therefor in the related
Canadian Bid Request, then, unless otherwise agreed by the Canadian Borrower,
the Administrative Agent and such Canadian Lenders, such Canadian Competitive
Bids shall be accepted as nearly as possible in proportion to the amount offered
by each such Canadian Lender in respect of such Interest Period, with such
accepted amounts being rounded to the nearest whole multiple of C$1,000,000.

         (g)      Notice to Canadian Lenders of Acceptance or Rejection of
Canadian Bids. The Administrative Agent shall promptly notify each Canadian
Lender having submitted a Canadian

                                                          DEVON CREDIT AGREEMENT

                                       57
<PAGE>

Competitive Bid whether or not its offer has been accepted and, if its offer has
been accepted, of the amount of the Canadian Bid Loan or Canadian Bid Loans to
be made by it on the date of the applicable Canadian Bid Borrowing. Any Canadian
Competitive Bid or portion thereof that is not accepted by the applicable
Canadian Borrower by the applicable time specified in Section 3.03(e) shall be
deemed rejected.

         (h)      Notice of Canadian Dollar Eurodollar Rate. If any Canadian Bid
Borrowing is to consist of Eurodollar Margin Loans, the Administrative Agent
shall determine the Canadian Dollar Eurodollar Rate for the relevant Interest
Period, and promptly after making such determination, shall notify the Canadian
Borrower and the Canadian Lenders that will be participating in such Canadian
Bid Borrowing of such Canadian Dollar Eurodollar Rate.

         (i)      Funding of Canadian Bid Loans. Each Canadian Lender that has
received notice pursuant to Section 3.03(g) that all or a portion of its
Canadian Competitive Bid has been accepted by the applicable Canadian Borrower
shall make the amount of its Canadian Bid Loan(s) available to the
Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than 1:00 p.m. on the date of the requested Canadian
Bid Borrowing. Upon satisfaction of the applicable conditions set forth in
Section 6.02, the Administrative Agent shall make all funds so received
available to the applicable Canadian Borrower in like funds as received by the
Administrative Agent.

         (j)      Notice of Range of Canadian Bids. After each Canadian
Competitive Bid auction pursuant to this Section 3.03, the Administrative Agent
shall notify each Canadian Lender that submitted a Canadian Competitive Bid in
such auction of the ranges of bids submitted (without the bidder's name) and
accepted for each Canadian Bid Loan and the aggregate amount of each Canadian
Bid Borrowing.

         3.04     CANADIAN LETTERS OF CREDIT.

         (a)      The Letter of Credit Commitment.

                  (i)      Subject to the terms and conditions set forth herein,
         (A) the Canadian L/C Issuer agrees, in reliance upon the agreements of
         the other Canadian Lenders set forth in this Section 3.04 (1) from time
         to time on any Business Day during the period from the Closing Date
         until the Letter of Credit Expiration Date, to issue Canadian Letters
         of Credit for the account of the applicable Canadian Borrower, and to
         amend or renew Canadian Letters of Credit previously issued by it, in
         accordance with subsection (b) below, and (2) to honor drawings under
         the Canadian Letters of Credit; and (B) the Canadian Lenders severally
         agree to participate in Canadian Letters of Credit issued for the
         account of a Canadian Borrower and any drawings thereunder; provided
         that after giving effect to any Canadian L/C Credit Extension with
         respect to any Letter of Credit, (x) the Total Canadian Outstandings
         shall not exceed the Aggregate Canadian Commitments, (y) the aggregate
         Outstanding Amount of the Canadian Committed Borrowings of any Canadian
         Lender, plus such Canadian Lender's Pro Rata Share of the Outstanding
         Amount of all Canadian L/C Obligations, plus such Canadian Lender's Pro
         Rata Share of the Outstanding Amount of all Canadian Swing Line Loans
         shall not

                                                          DEVON CREDIT AGREEMENT

                                       58
<PAGE>

         exceed such Canadian Lender's Canadian Commitment, and (z) the
         Outstanding Amount of the Canadian L/C Obligations shall not exceed the
         Canadian Letter of Credit Sublimit. Each request by a Canadian Borrower
         for the issuance or amendment of a Letter of Credit shall be deemed to
         be a representation by such Canadian Borrower that the Canadian L/C
         Credit Extension so requested complies with the conditions set forth in
         the proviso to the preceding sentence. Within the foregoing limits, and
         subject to the terms and conditions hereof, each Canadian Borrower's
         ability to obtain Canadian Letters of Credit shall be fully revolving,
         and accordingly each Canadian Borrower may, during the foregoing
         period, obtain Canadian Letters of Credit to replace Canadian Letters
         of Credit that have expired or that have been drawn upon and
         reimbursed. All Existing Canadian Letters of Credit shall be deemed to
         have been issued pursuant hereto, and from and after the Closing Date
         shall be subject to and governed by the terms and conditions hereof.

                  (ii)     The Canadian L/C Issuer shall not issue any Letter of
         Credit if the expiry date of such requested Letter of Credit would
         occur after the Letter of Credit Expiration Date, unless all the
         Canadian Lenders have approved such expiry date.

                  (iii)    The Canadian L/C Issuer shall not be under any
         obligation to issue any Letter of Credit if:

                           (A)      any order, judgment or decree of any
                  Governmental Authority or arbitrator shall by its terms
                  purport to enjoin or restrain the Canadian L/C Issuer from
                  issuing such Letter of Credit, or any Law applicable to the
                  Canadian L/C Issuer or any request or directive (whether or
                  not having the force of law) from any Governmental Authority
                  with jurisdiction over the Canadian L/C Issuer shall prohibit,
                  or request that the Canadian L/C Issuer refrain from, the
                  issuance of letters of credit generally or such Letter of
                  Credit in particular or shall impose upon the Canadian L/C
                  Issuer with respect to such Letter of Credit any restriction,
                  reserve or capital requirement (for which the Canadian L/C
                  Issuer is not otherwise compensated hereunder) not in effect
                  on the Closing Date, or shall impose upon the Canadian L/C
                  Issuer any unreimbursed loss, cost or expense which was not
                  applicable on the Closing Date and which the Canadian L/C
                  Issuer in good faith deems material to it, unless the
                  applicable Canadian Borrower confirms that it will pay the
                  foregoing;

                           (B)      the issuance of such Letter of Credit would
                  violate any Laws;

                           (C)      except as otherwise agreed by the
                  Administrative Agent and the Canadian L/C Issuer, such Letter
                  of Credit is in an initial face amount less than C$10,000 or
                  US $10,000, as the case may be;

                           (D)      such Letter of Credit is to be denominated
                  in a currency other than Canadian Dollars or US Dollars; or

                           (E)      the Canadian L/C Issuer is Royal Bank of
                  Canada and the Canadian L/C Obligations relating to Letters of
                  Credit issued by Royal Bank of

                  Canada as Canadian L/C Issuer hereunder exceed US $125,000,000
                  unless otherwise agreed to by Royal Bank of Canada.

                  (iv)     The Canadian L/C Issuer shall not amend any Letter of
         Credit if the Canadian L/C Issuer would not be permitted at such time
         to issue such Letter of Credit in its amended form under the terms
         hereof.

                  (v)      The Canadian L/C Issuer shall be under no obligation
         to amend any Letter of Credit if (A) the Canadian L/C Issuer would have
         no obligation at such time to issue such Letter of Credit in its
         amended form under the terms hereof, or (B) the beneficiary of such
         Letter of Credit does not accept the proposed amendment to such Letter
         of Credit.

         (b)      Procedures for Issuance and Amendment of Canadian Letters of
Credit.

                  (i)      Each Canadian Letter of Credit shall be issued or
         amended, as the case may be, upon the request of the applicable
         Canadian Borrower delivered to the Canadian L/C Issuer (with a copy to
         the Administrative Agent) in the form of a Canadian Letter of Credit
         Application, appropriately completed and signed by a Responsible
         Officer of the applicable Canadian Borrower. Such Canadian Letter of
         Credit Application must be received by the Canadian L/C Issuer and the
         Administrative Agent not later than 11:00 a.m. at least three Business
         Days (or such later date and time as the Administrative Agent and the
         Canadian L/C Issuer may agree in a particular instance in their sole
         discretion) prior to the proposed issuance date or date of amendment,
         as the case may be. In the case of a request for an initial issuance of
         a Canadian Letter of Credit, such Canadian Letter of Credit Application
         shall specify in form and detail satisfactory to the Canadian L/C
         Issuer: (A) the proposed issuance date of the requested Canadian Letter
         of Credit (which shall be a Business Day); (B) the amount thereof; (C)
         the expiry date thereof; (D) the name and address of the beneficiary
         thereof; (E) the documents to be presented by such beneficiary in case
         of any drawing thereunder; (F) the full text of any certificate to be
         presented by such beneficiary in case of any drawing thereunder; and
         (G) such other matters as the Canadian L/C Issuer may reasonably
         require. In the case of a request for an amendment of any outstanding
         Canadian Letter of Credit, such Canadian Letter of Credit Application
         shall specify in form and detail satisfactory to the Canadian L/C
         Issuer (A) the Canadian Letter of Credit to be amended; (B) the
         proposed date of amendment thereof (which shall be a Business Day); (C)
         the nature of the proposed amendment; and (D) such other matters as the
         Canadian L/C Issuer may require. Additionally, the applicable Canadian
         Borrower shall furnish to the Canadian L/C Issuer and the
         Administrative Agent such other documents and information pertaining to
         such requested Letter of Credit issuance or amendment, including any
         Issuer Documents, as the Canadian L/C Issuer or the Administrative
         Agent may reasonably require.

                  (ii)     Promptly after receipt of any Canadian Letter of
         Credit Application, the Canadian L/C Issuer will confirm with the
         Administrative Agent (by telephone or in writing) that the
         Administrative Agent has received a copy of such Canadian Letter of
         Credit Application from the applicable Canadian Borrower and, if not,
         the Canadian L/C Issuer will provide the Administrative Agent with a
         copy thereof. Unless the Canadian

                                                          DEVON CREDIT AGREEMENT

                                       60
<PAGE>

         L/C Issuer has received written notice from any Canadian Lender, the
         Administrative Agent or any Loan Party, at least one Business Day prior
         to the requested date of issuance or amendment of the applicable Letter
         of Credit, that one or more applicable conditions contained in Article
         VI shall not then be satisfied, then, subject to the terms and
         conditions hereof, the Canadian L/C Issuer shall, on the requested
         date, issue a Letter of Credit for the account of the applicable
         Canadian Borrower or enter into the applicable amendment, as the case
         may be, in each case in accordance with the Canadian L/C Issuer's usual
         and customary business practices. Immediately upon the issuance of each
         Canadian Letter of Credit, each Canadian Lender shall be deemed to, and
         hereby irrevocably and unconditionally agrees to, purchase from the
         Canadian L/C Issuer a risk participation in such Canadian Letter of
         Credit in an amount equal to the product of such Canadian Lender's Pro
         Rata Share times the amount of such Canadian Letter of Credit.

                  (iii)    Promptly after its delivery of any Canadian Letter of
         Credit or any amendment to a Canadian Letter of Credit to an advising
         bank with respect thereto or to the beneficiary thereof, the Canadian
         L/C Issuer will also deliver to the applicable Canadian Borrower and
         the Administrative Agent a true and complete copy of such Canadian
         Letter of Credit or amendment.

         (c)      Drawings and Reimbursements; Funding of Participations.

                  (i)      Upon receipt from the beneficiary of any Canadian
         Letter of Credit of any notice of a drawing under such Letter of
         Credit, the Canadian L/C Issuer shall notify the applicable Canadian
         Borrower and the Administrative Agent thereof. Not later than 11:00
         a.m. on the date of any payment by the Canadian L/C Issuer under a
         Letter of Credit (each such date, a "Canadian Honor Date"), the
         applicable Canadian Borrower shall reimburse the Canadian L/C Issuer
         through the Administrative Agent in an amount equal to the amount of
         such drawing whether by way of Canadian Prime Rate Committed Loans or
         Canadian Base Rate Committed Loans or otherwise. If the applicable
         Canadian Borrower fails so to reimburse the Canadian L/C Issuer by such
         time, the Administrative Agent shall promptly notify each Canadian
         Lender of the Canadian Honor Date, the amount of the unreimbursed
         drawing (the "Canadian Unreimbursed Amount"), and the amount of such
         Canadian Lender's Pro Rata Share thereof. In such event, the applicable
         Canadian Borrower shall be deemed to have requested a Canadian
         Committed Borrowing of Canadian Prime Rate Committed Loans or Canadian
         Base Rate Committed Loans, if applicable, to be disbursed on the
         Canadian Honor Date in an amount equal to the Canadian Unreimbursed
         Amount, without regard to the minimum and multiples specified in
         Section 3.02 for the principal amount of Canadian Prime Rate Committed
         Loans or Canadian Base Rate Committed Loans, but subject to the amount
         of the unutilized portion of the Aggregate Canadian Commitments and
         whether or not the conditions set forth in Section 6.02 are satisfied.
         Any notice given by the Canadian L/C Issuer or the Administrative Agent
         pursuant to this Section 3.04(c)(i) may be given by telephone if
         immediately confirmed in writing; provided that the lack of such an
         immediate confirmation shall not affect the conclusiveness or binding
         effect of such notice.

                  (ii)     Each Canadian Lender (including the Canadian Lender
         acting as Canadian L/C Issuer) shall upon any notice pursuant to
         Section 3.04(c)(i) make funds available to the Administrative Agent for
         the account of the Canadian L/C Issuer at the Administrative Agent's
         Office in an amount equal to its Pro Rata Share of the Canadian
         Unreimbursed Amount not later than 1:00 p.m. on the Business Day
         specified in such notice by the Administrative Agent, whereupon,
         subject to the provisions of Section 3.04(c)(iii), each Canadian Lender
         that so makes funds available shall be deemed to have made a Canadian
         Loan in the form of a Canadian Prime Rate Committed Loan or Canadian
         Base Rate Committed Loans, to the applicable Canadian Borrower in such
         amount. The Administrative Agent shall remit the funds so received to
         the Canadian L/C Issuer.

                  (iii)    With respect to any Canadian Unreimbursed Amount that
         is not fully refinanced by Canadian Prime Rate Committed Loans or
         Canadian Base Rate Committed Loans because the conditions set forth in
         Section 6.02 cannot be satisfied or for any other reason, the
         applicable Canadian Borrower shall be deemed to have incurred from the
         Canadian L/C Issuer a Canadian L/C Borrowing in the amount of the
         Canadian Unreimbursed Amount that is not so refinanced, which Canadian
         L/C Borrowing shall be due and payable on demand (together with
         interest) and shall bear interest at a rate per annum equal to (i) for
         the first three (3) Business Days after the date of such Canadian L/C
         Borrowing, the Canadian Prime Rate or the Canadian US Dollar Base Rate,
         as applicable, and (ii) thereafter such rate plus two percent (2%). In
         such event, each Canadian Lender's payment to the Administrative Agent
         for the account of the Canadian L/C Issuer pursuant to Section
         3.04(c)(ii) shall be deemed payment in respect of its participation in
         such Canadian L/C Borrowing and shall constitute a Canadian L/C Advance
         from such Canadian Lender in satisfaction of its participation
         obligation under this Section 3.04.

                  (iv)     Until each Canadian Lender funds its Canadian
         Committed Loan or Canadian L/C Advance pursuant to this Section 3.04(c)
         to reimburse the Canadian L/C Issuer for any amount drawn under any
         Letter of Credit, interest in respect of such Canadian Lender's Pro
         Rata Share of such amount shall be solely for the account of the
         Canadian L/C Issuer.

                  (v)      Each Canadian Lender's obligation to make Canadian
         Committed Loans or Canadian L/C Advances to reimburse the Canadian L/C
         Issuer for amounts drawn under Canadian Letters of Credit, as
         contemplated by this Section 3.04(c), shall be absolute and
         unconditional and shall not be affected by any circumstance, including
         (A) any set-off, counterclaim, recoupment, defense or other right which
         such Canadian Lender may have against the Canadian L/C Issuer, the
         applicable Canadian Borrower or any other Person for any reason
         whatsoever; (B) the occurrence or continuance of a Default, or (C) any
         other occurrence, event or condition, whether or not similar to any of
         the foregoing. No such making of a Canadian L/C Advance shall relieve
         or otherwise impair the obligation of the applicable Canadian Borrower
         to reimburse the Canadian L/C Issuer for the amount of any payment made
         by the Canadian L/C Issuer under any Letter of Credit, together with
         interest as provided herein.

                                                          DEVON CREDIT AGREEMENT

<PAGE>

                  (vi)     If any Canadian Lender fails to make available to the
         Administrative Agent for the account of the Canadian L/C Issuer any
         amount required to be paid by such Canadian Lender pursuant to the
         foregoing provisions of this Section 3.04(c) by the time specified in
         Section 3.04(c), the Canadian L/C Issuer shall be entitled to recover
         from such Canadian Lender (acting through the Administrative Agent), on
         demand, such amount with interest thereon for the period from the date
         such payment is required to the date on which such payment is
         immediately available to the Canadian L/C Issuer at a rate per annum
         equal to the Canadian Prime Rate or the Canadian US Dollar Base Rate,
         as applicable, from time to time in effect. A certificate of the
         Canadian L/C Issuer submitted to any Canadian Lender (through the
         Administrative Agent) with respect to any amounts owing under this
         clause (vi) shall be conclusive absent manifest error.

         (d)      Repayment of Participations.

                  (i)      At any time after the Canadian L/C Issuer has made a
         payment under any Letter of Credit and has received from any Canadian
         Lender such Canadian Lender's Canadian L/C Advance in respect of such
         payment in accordance with Section 3.04(c), if the Administrative Agent
         receives for the account of the Canadian L/C Issuer any payment in
         respect of the related Canadian Unreimbursed Amount or interest thereon
         (whether directly from the applicable Canadian Borrower or otherwise,
         including proceeds of Cash Collateral applied thereto by the
         Administrative Agent), the Administrative Agent will distribute to such
         Canadian Lender its Pro Rata Share thereof (appropriately adjusted, in
         the case of interest payments, to reflect the period of time during
         which such Canadian Lender's Canadian L/C Advance was outstanding) in
         the same funds as those received by the Administrative Agent.

                  (ii)     If any payment received by the Administrative Agent
         for the account of the Canadian L/C Issuer pursuant to Section
         3.04(c)(i) is required to be returned under any of the circumstances
         described in Section 12.07 (including pursuant to any settlement
         entered into by the Canadian L/C Issuer in its discretion), each
         Canadian Lender shall pay to the Administrative Agent for the account
         of the Canadian L/C Issuer its Pro Rata Share thereof on demand of the
         Administrative Agent, plus interest thereon from the date of such
         demand to the date such amount is returned by such Canadian Lender, at
         a rate per annum equal to the Canadian Prime Rate or Canadian US Dollar
         Base Rate, as applicable, from time to time in effect.

         (e)      Obligations Absolute. The obligation of the applicable
Canadian Borrower to reimburse the Canadian L/C Issuer for each drawing under
each Letter of Credit and to repay each Canadian L/C Borrowing shall be
absolute, unconditional and irrevocable, and shall be paid strictly in
accordance with the terms of this Agreement under all circumstances, including
the following:

                  (i)      any lack of validity or enforceability of such Letter
         of Credit, this Agreement, or any other Loan Document;

                                                          DEVON CREDIT AGREEMENT

                                       63
<PAGE>

                  (ii)     the existence of any claim, counterclaim, set-off,
         defense or other right that the applicable Canadian Borrower or any
         Subsidiary may have at any time against any beneficiary or any
         transferee of such Letter of Credit (or any Person for whom any such
         beneficiary or any such transferee may be acting), the Canadian L/C
         Issuer or any other Person, whether in connection with this Agreement,
         the transactions contemplated hereby or by such Letter of Credit or any
         agreement or instrument relating thereto, or any unrelated transaction;

                  (iii)    any draft, demand, certificate or other document
         presented under such Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect; or any loss or delay in the
         transmission or otherwise of any document required in order to make a
         drawing under such Letter of Credit;

                  (iv)     any payment by the Canadian L/C Issuer under such
         Letter of Credit against presentation of a draft or certificate that
         does not strictly comply with the terms of such Letter of Credit; or
         any payment made by the Canadian L/C Issuer under such Letter of Credit
         to any Person purporting to be a trustee in bankruptcy,
         debtor-in-possession, assignee for the benefit of creditors,
         liquidator, receiver or other representative of or successor to any
         beneficiary or any transferee of such Letter of Credit, including any
         arising in connection with any proceeding under any Debtor Relief Law;
         or

                  (v)      any other circumstance or happening whatsoever,
         whether or not similar to any of the foregoing, including any other
         circumstance that might otherwise constitute a defense available to, or
         a discharge of, any Canadian Borrower or any Subsidiary.

         The applicable Canadian Borrower shall promptly examine a copy of each
Letter of Credit and each amendment thereto that is delivered to it and, in the
event of any claim of noncompliance with such Canadian Borrower's instructions
or other irregularity, the applicable Canadian Borrower will promptly notify the
Canadian L/C Issuer. Such Canadian Borrower shall be conclusively deemed to have
waived any such claim against the Canadian L/C Issuer and its correspondents
unless such notice is given as aforesaid.

         (f)      Role of Canadian L/C Issuer. Each Canadian Lender and each
Canadian Borrower agree that, in paying any drawing under a Letter of Credit,
the Canadian L/C Issuer shall not have any responsibility to obtain any document
(other than any sight draft, certificates and documents expressly required by
the Letter of Credit) or to ascertain or inquire as to the validity or accuracy
of any such document or the authority of the Person executing or delivering any
such document. None of the Canadian L/C Issuer, any Agent-Related Person nor any
of the respective correspondents, participants or assignees of the Canadian L/C
Issuer shall be liable to any Canadian Lender for (i) any action taken or
omitted in connection herewith at the request or with the approval of the
Canadian Lenders or the Canadian Required Lenders, as applicable; (ii) any
action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any document or instrument related to any Letter of Credit or
Letter of Credit Application. Each Canadian Borrower hereby assumes all risks of
the acts or omissions of any beneficiary or transferee with respect to its use

                                                          DEVON CREDIT AGREEMENT

                                       64
<PAGE>

of any Letter of Credit; provided, however, that this assumption is not intended
to, and shall not, preclude such Canadian Borrower's pursuing such rights and
remedies as it may have against the beneficiary or transferee at law or under
any other agreement. None of the Canadian L/C Issuer, any Agent-Related Person,
nor any of the respective correspondents, participants or assignees of the
Canadian L/C Issuer, shall be liable or responsible for any of the matters
described in clauses (i) through (v) of Section 3.04(e); provided, however, that
anything in such clauses to the contrary notwithstanding, the applicable
Canadian Borrower may have a claim against the Canadian L/C Issuer, and the
Canadian L/C Issuer may be liable to such Canadian Borrower, to the extent, but
only to the extent, of any direct, as opposed to consequential or exemplary,
damages suffered by the applicable Canadian Borrower which such Canadian
Borrower proves were caused by the Canadian L/C Issuer's willful misconduct or
gross negligence or the Canadian L/C Issuer's willful failure to pay under any
Letter of Credit after the presentation to it by the beneficiary of a sight
draft and certificate(s) strictly complying with the terms and conditions of a
Letter of Credit. In furtherance and not in limitation of the foregoing, the
Canadian L/C Issuer may accept documents that appear on their face to be in
order, without responsibility for further investigation, and the Canadian L/C
Issuer shall not be responsible for the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign a
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason.

         (g)      Cash Collateral. Upon the request of the Administrative Agent,
(i) if the Canadian L/C Issuer has honored any full or partial drawing request
under any Letter of Credit and such drawing has resulted in a Canadian L/C
Borrowing, or (ii) if, as of the Letter of Credit Expiration Date, any Letter of
Credit for any reason remains outstanding and partially or wholly undrawn, the
applicable Canadian Borrower shall immediately Cash Collateralize the then
Outstanding Amount of all Canadian L/C Obligations (in an amount equal to such
Outstanding Amount determined as of the date of such Canadian L/C Borrowing or
the Letter of Credit Expiration Date, as the case may be). Sections 2.06 and
10.02(c) set forth certain additional requirements to deliver Cash Collateral
hereunder. The applicable Canadian Borrower hereby grants to the Administrative
Agent, for the benefit of the Canadian L/C Issuer and the Canadian Lenders, a
security interest in all such cash, deposit accounts and all balances therein
and all proceeds of the foregoing. Such Cash Collateral shall be maintained in
blocked, deposit accounts at Bank of America. Pending application thereof, such
Cash Collateral shall be invested by the applicable Canadian L/C Issuer in such
investments as Canadian L/C Issuer may choose in its sole discretion. All
interest on (and other proceeds of) such investments shall be reinvested or
applied to Canadian L/C Obligations or other Canadian Obligations which are due
and payable.

         (h)      Applicability of ISP98 and UCP. Unless otherwise expressly
agreed by the Canadian L/C Issuer and the applicable Canadian Borrower when a
Letter of Credit is issued (including any such agreement applicable to an
Existing Canadian Letter of Credit), (i) the rules of the ISP shall apply to
each standby Letter of Credit, and (ii) the rules of the Uniform Customs and
Practice for Documentary Credits, as most recently published by the
International Chamber of Commerce at the time of issuance shall apply to each
commercial Letter of Credit.

                                                          DEVON CREDIT AGREEMENT

<PAGE>

         (i)      Letter of Credit Fees. The applicable Canadian Borrower shall
pay to the Administrative Agent for the account of each Canadian Lender in
accordance with its Pro Rata Share a Letter of Credit fee (the "Canadian Letter
of Credit Fee") for each Letter of Credit equal to the Applicable Rate times the
daily maximum amount available to be drawn under such Letter of Credit (whether
or not such maximum amount is then in effect under such Letter of Credit).
Canadian Letter of Credit Fees shall be (i) computed on a quarterly basis in
arrears and (ii) due and payable on the last Business Day of each March, June,
September and December, commencing with the first such date to occur after the
issuance of such Letter of Credit, on the Letter of Credit Expiration Date and
thereafter on demand. If there is any change in the Applicable Rate during any
quarter, the daily maximum amount of each standby Letter of Credit shall be
computed and multiplied by the Applicable Rate separately for each period during
such quarter that such Applicable Rate was in effect.

         (j)      Fronting Fee and Documentary and Processing Charges Payable to
Canadian L/C Issuer. The applicable Canadian Borrower shall pay directly to the
Canadian L/C Issuer for its own account a fronting fee with respect to each
Letter of Credit in the amount specified in the Fee Letter, payable on the
actual daily maximum amount available to be drawn under such Letter of Credit
(whether or not such maximum amount is then in effect under such Letter of
Credit). Such fronting fee shall be computed on a quarterly basis in arrears.
Such fronting fee shall be due and payable on the first Business Day after the
end of each March, June, September and December, commencing with the first such
date to occur after the issuance of such Letter of Credit, on the Letter of
Credit Expiration Date and thereafter on demand. In addition, the Canadian
Borrower shall pay directly to the Canadian L/C Issuer for its own account the
customary issuance, presentation, amendment and other processing fees, and other
standard costs and charges, of the Canadian L/C Issuer relating to letters of
credit as agreed to by the Canadian Borrowers and the applicable Canadian L/C
Issuer. Such customary fees and standard costs and charges are due and payable
on demand and are nonrefundable.

         (k)      Conflict with Issuer Documents. In the event of any conflict
between the terms hereof and the terms of any Issuer Document, the terms hereof
shall control.

         (l)      Designation of Subsidiaries as Account Parties.
Notwithstanding anything to the contrary set forth in this Agreement, including
without limitation Section 3.04(a), a Canadian Letter of Credit issued hereunder
shall, upon the request of either Canadian Borrower, be issued for the account
of any Subsidiary of such Canadian Borrower, provided that notwithstanding such
request, the applicable Canadian Borrower shall be the actual account party for
all purposes of this Agreement for such Canadian Letter of Credit and such
request shall not affect the applicable Canadian Borrower's reimbursement
obligations hereunder with respect to such Canadian Letter of Credit.

         3.05     CANADIAN SWING LINE LOANS.

         (a)      The Canadian Swing Line. Subject to the terms and conditions
set forth herein, the Canadian Swing Line Lender agrees to make loans (each such
loan, a "Canadian Swing Line Loan") to each Canadian Borrower from time to time
on any Business Day during the Availability Period in an aggregate amount not to
exceed at any time outstanding the amount of

                                                          DEVON CREDIT AGREEMENT

                                       66
<PAGE>

the Canadian Swing Line Sublimit, notwithstanding the fact that such Canadian
Swing Line Loans, when aggregated with the Pro Rata Share of the Outstanding
Canadian Committed Borrowings and Canadian L/C Obligations of the Canadian
Lender acting as Canadian Swing Line Lender, may exceed the amount of such
Canadian Lender's Canadian Commitment; provided, however, that after giving
effect to any Canadian Swing Line Loan, (i) the Total Canadian Outstandings
shall not exceed the Aggregate Canadian Commitments, and (ii) the aggregate
Outstanding Amount of the Canadian Committed Loans of any Canadian Lender, plus
such Canadian Lender's Pro Rata Share of the Outstanding Amount of all Canadian
L/C Obligations, plus such Canadian Lender's Pro Rata Share of the Outstanding
Amount of all Canadian Swing Line Loans plus such Canadian Lender's Bankers'
Acceptances shall not exceed such Canadian Lender's Canadian Commitment, and
provided, further, that the applicable Canadian Borrower shall not use the
proceeds of any Canadian Swing Line Loan to refinance any outstanding Canadian
Swing Line Loan. Within the foregoing limits, and subject to any other terms and
conditions hereof, the applicable Canadian Borrower may borrow under this
Section 3.05, prepay under Section 3.06, and reborrow under this Section
3.05(a). Immediately upon the making of a Canadian Swing Line Loan, each
Canadian Lender shall be deemed to, and hereby irrevocably and unconditionally
agrees to, purchase from the Canadian Swing Line Lender a risk participation in
such Canadian Swing Line Loan in an amount equal to the product of such Canadian
Lender's Pro Rata Share times the amount of such Canadian Swing Line Loan.

         (b)      Canadian Borrowing Procedures. Each Canadian Swing Line
Borrowing shall be made upon the applicable Canadian Borrower's irrevocable
notice to the Canadian Swing Line Lender and the Administrative Agent, which may
be given by telephone. Each such notice must be received by the Canadian Swing
Line Lender and the Administrative Agent not later than 3:00 p.m. on the
requested borrowing date, and shall specify (i) the amount to be borrowed, which
may be in Canadian Dollars or in US Dollars and shall be a minimum of $1,000,000
of such currency, and (ii) the requested borrowing date, which shall be a
Business Day. Each such telephonic notice must be confirmed promptly by delivery
to the Canadian Swing Line Lender and the Administrative Agent of a written
Canadian Swing Line Loan Notice, appropriately completed and signed by a
Responsible Officer of the applicable Canadian Borrower. Promptly after receipt
by the Canadian Swing Line Lender of any telephonic Canadian Swing Line Loan
Notice, the Canadian Swing Line Lender will confirm with the Administrative
Agent (by telephone or in writing) that the Administrative Agent has also
received such Canadian Swing Line Loan Notice and, if not, the Canadian Swing
Line Lender will notify the Administrative Agent (by telephone or in writing) of
the contents thereof. Unless the Canadian Swing Line Lender has received notice
(by telephone or in writing) from the Administrative Agent (including at the
request of any Canadian Lender) prior to 1:00 p.m. for Canadian Swing Line
Borrowings made in US Dollars and 3:00 p.m. for Canadian Swing Line Borrowings
made in Canadian Dollars, in each case on the date of the proposed Canadian
Swing Line Borrowing (A) directing the Canadian Swing Line Lender not to make
such Canadian Swing Line Loan as a result of the limitations set forth in the
proviso to the first sentence of Section 3.05(a), or (B) that one or more of the
applicable conditions specified in Article VI is not then satisfied, then,
subject to the terms and conditions hereof, the Canadian Swing Line Lender will,
not later than 5:00 p.m. on the borrowing date specified in such Canadian Swing
Line Loan Notice, make the amount of its Canadian Swing Line Loan available to
the applicable Canadian Borrower at its office either

                                                          DEVON CREDIT AGREEMENT

                                       67
<PAGE>

by (i) crediting the account of such Canadian Borrower on the books of the
Canadian Swing Line Lender in immediately available funds or (ii) wire transfer
of such funds, in each case in accordance with instructions provided to (and
reasonably acceptable to) the Administrative Agent by the applicable Canadian
Borrower.

         (c)      Refinancing of Canadian Swing Line Loans.

                  (i)      The Canadian Swing Line Lender at any time in its
         sole and absolute discretion may request, on behalf of the applicable
         Canadian Borrower (which hereby irrevocably authorizes the Canadian
         Swing Line Lender to so request on its behalf), that each Canadian
         Lender make a Canadian Prime Rate Committed Loan or a Canadian Base
         Rate Committed Loan, as applicable, in an amount equal to such Canadian
         Lender's Pro Rata Share of the amount of Canadian Swing Line Loans then
         outstanding. Such request shall be made in writing (which written
         request shall be deemed to be a Canadian Committed Borrowing Notice for
         purposes hereof) and in accordance with the requirements of Section
         3.02, without regard to the minimum and multiples specified therein for
         the principal amount of Canadian Prime Rate Committed Loans or Canadian
         Base Rate Committed Loans, but subject to the unutilized portion of the
         Aggregate Canadian Commitments and the conditions set forth in Section
         6.02. The Canadian Swing Line Lender shall furnish the applicable
         Canadian Borrower with a copy of the applicable Canadian Committed
         Borrowing Notice promptly after delivering such notice to the
         Administrative Agent. Each Canadian Lender shall make an amount equal
         to its Pro Rata Share of the amount specified in such Canadian
         Committed Borrowing Notice available to the Administrative Agent in
         immediately available funds for the account of the Canadian Swing Line
         Lender at the Administrative Agent's Office not later than 1:00 p.m. on
         the day specified in such Canadian Committed Borrowing Notice,
         whereupon, subject to Section 3.05(c)(ii), each Canadian Lender that so
         makes funds available shall be deemed to have made a Canadian Prime
         Rate Committed Loan or Canadian Base Rate Committed Loan, as
         applicable, to the Canadian Borrower in such amount. The Administrative
         Agent shall remit the funds so received to the Canadian Swing Line
         Lender.

                  (ii)     If for any reason any Canadian Swing Line Loan cannot
         be refinanced by such a Canadian Committed Borrowing in accordance with
         Section 3.05(c)(i), the request for Canadian Prime Rate Committed Loans
         or Canadian Base Rate Committed Loans, as applicable, submitted by the
         Canadian Swing Line Lender as set forth herein shall be deemed to be a
         request by the Canadian Swing Line Lender that each of the Canadian
         Lenders fund its risk participation in the relevant Canadian Swing Line
         Loan and each Canadian Lender's payment to the Administrative Agent for
         the account of the Canadian Swing Line Lender pursuant to Section
         3.05(c)(i) shall be deemed payment in respect of such participation.

                  (iii)    If any Canadian Lender fails to make available to the
         Administrative Agent for the account of the Canadian Swing Line Lender
         any amount required to be paid by such Canadian Lender pursuant to the
         foregoing provisions of this Section 3.05(c) by the time specified in
         Section 3.05(c)(i), the Canadian Swing Line Lender shall be entitled

                                                          DEVON CREDIT AGREEMENT

                                       68

         to recover from such Canadian Lender (acting through the Administrative
         Agent), on demand, such amount with interest thereon for the period
         from the date such payment is required to the date on which such
         payment is immediately available to the Canadian Swing Line Lender at a
         rate per annum equal to the Canadian Prime Rate or Canadian US Dollar
         Base Rate from time to time in effect. A certificate of the Canadian
         Swing Line Lender submitted to any Canadian Lender (through the
         Administrative Agent) with respect to any amounts owing under this
         clause (iii) shall be conclusive absent manifest error.

                  (iv)     Each Canadian Lender's obligation to make Canadian
         Committed Loans or to purchase and fund risk participations in Canadian
         Swing Line Loans pursuant to this Section 3.05(c) shall be absolute and
         unconditional and shall not be affected by any circumstance, including
         (A) any set-off, counterclaim, recoupment, defense or other right which
         such Canadian Lender may have against the Canadian Swing Line Lender,
         the applicable Canadian Borrower or any other Person for any reason
         whatsoever, (B) the occurrence or continuance of a Default, or (C) any
         other occurrence, event or condition, whether or not similar to any of
         the foregoing; provided, however, that each Canadian Lender's
         obligation to make Canadian Committed Loans pursuant to this Section
         3.05(c) is subject to the conditions set forth in Section 6.02. No such
         funding of risk participations shall relieve or otherwise impair the
         obligation of the applicable Canadian Borrower to repay Canadian Swing
         Line Loans, together with interest as provided herein.

         (d)      Repayment of Participations.

                  (i)      At any time after any Canadian Lender has purchased
         and funded a risk participation in a Canadian Swing Line Loan, if the
         Canadian Swing Line Lender receives any payment on account of such
         Canadian Swing Line Loan, the Canadian Swing Line Lender will
         distribute to such Canadian Lender its Pro Rata Share of such payment
         (appropriately adjusted, in the case of interest payments, to reflect
         the period of time during which such Canadian Lender's risk
         participation was funded) in the same funds as those received by the
         Canadian Swing Line Lender.

                  (ii)     If any payment received by the Canadian Swing Line
         Lender in respect of principal or interest on any Canadian Swing Line
         Loan is required to be returned by the Canadian Swing Line Lender under
         any of the circumstances described in Section 12.07 (including pursuant
         to any settlement entered into by the Canadian Swing Line Lender in its
         discretion), each Canadian Lender shall pay to the Canadian Swing Line
         Lender its Pro Rata Share thereof on demand of the Administrative
         Agent, plus interest thereon from the date of such demand to the date
         such amount is returned, at a rate per annum equal to the Canadian
         Prime Rate or Canadian US Dollar Base Rate, as applicable. The
         Administrative Agent will make such demand upon the request of the
         Canadian Swing Line Lender.

         (e)      Interest for Account of Canadian Swing Line Lender. The
Canadian Swing Line Lender shall be responsible for invoicing the applicable
Canadian Borrower for interest on the Canadian Swing Line Loans. Until each
Canadian Lender funds its Canadian Prime Rate

Committed Loan , its Canadian Base Rate Committed Loan or its risk participation
pursuant to this Section 3.05 to refinance such Canadian Lender's Pro Rata Share
of any Canadian Swing Line Loan, interest in respect of such Pro Rata Share
shall be solely for the account of the Canadian Swing Line Lender.

         (f)      Payments Directly to Canadian Swing Line Lender. The
applicable Canadian Borrower shall make all payments of principal and interest
in respect of the Canadian Swing Line Loans directly to the Canadian Swing Line
Lender.

         3.06     PREPAYMENTS.

         (a)      Each Canadian Borrower may, upon notice to the Administrative
Agent, at any time or from time to time voluntarily prepay Canadian Committed
Loans in whole or in part without premium or penalty; provided that (i) such
notice must be received by the Administrative Agent not later than 11:00 a.m.
(A) three Business Days prior to any date of prepayment of Canadian Eurodollar
Rate Committed Loans or Canadian US Eurodollar Rate Committed Loans and (B) on
the date of prepayment of Canadian Prime Rate Committed Loans and Canadian Base
Rate , (ii) any prepayment of Canadian Eurodollar Rate Committed Loans shall be
in a principal amount of C$5,000,000 or a whole multiple of C$1,000,000 in
excess thereof; (ii) any prepayment of Canadian US Eurodollar Rate Committed
Loans shall be in a principal amount of US $5,000,000 or a whole multiple of US
$1,000,000 in excess thereof; (iii) any prepayment of Canadian Prime Rate
Committed Loans shall be in a principal amount of C$1,000,000 or a whole
multiple of C$100,000 in excess thereof; and (iv) any prepayment of Canadian
Base Rate Committed Loans shall be in a principal amount of US $1,000,000 or a
whole multiple of US $100,000 in excess thereof or, in each case, if less, the
entire principal amount thereof then outstanding. Each such notice shall specify
the date and amount of such prepayment and the Type(s) of Canadian Committed
Loans to be prepaid. The Administrative Agent will promptly notify each Canadian
Lender of its receipt of each such notice, and of the amount of such Canadian
Lender's Pro Rata Share of such prepayment. If such notice is given by a
Canadian Borrower, such Canadian Borrower shall make such prepayment and the
payment amount specified in such notice shall be due and payable on the date
specified therein. Any prepayment of a Canadian Dollar Eurodollar Rate Loan
shall be accompanied by all accrued interest thereon, together with any
additional amounts required pursuant to Section 5.05. Each such prepayment shall
be applied to the Canadian Committed Loans of the Canadian Lenders in accordance
with their respective Pro Rata Shares.

         (b)      No Canadian Bid Loan may be prepaid without the prior consent
of the applicable Canadian Bid Loan Lender.

         (c)      Each Canadian Borrower may, upon notice to the Canadian Swing
Line Lender (with a copy to the Administrative Agent), at any time or from time
to time, voluntarily prepay Canadian Swing Line Loans in whole or in part
without premium or penalty; provided that (i) such notice must be received by
the Canadian Swing Line Lender and the Administrative Agent not later than 1:00
p.m. on the date of the prepayment, and (ii) any such prepayment shall be in a
minimum principal amount of C $1,000,000 or US $1,000,000, as applicable. Each
such notice shall specify the date and amount of such prepayment. If such notice
is given by a

                                                          DEVON CREDIT AGREEMENT

                                       70
<PAGE>

Canadian Borrower, such Canadian Borrower shall make such prepayment and the
payment amount specified in such notice shall be due and payable on the date
specified therein.

         (d)      If for any reason the Total Canadian Outstandings at any time
exceed the Aggregate Canadian Commitments then in effect, each Canadian Borrower
shall immediately prepay Loans and/or Cash Collateralize the Canadian L/C
Obligations in an aggregate amount equal to such excess (on a proportionate
basis having regard to the Loans and Canadian L/C Obligations of each Canadian
Borrower); provided, however, that the Canadian Borrowers shall not be required
to Cash Collateralize the Canadian L/C Obligations pursuant to this Section
3.06(d) unless after the prepayment in full of the Canadian Committed Loans and
Canadian Swing Line Loans the Total Canadian Outstandings exceed the Aggregate
Canadian Commitments then in effect.

         3.07     REPAYMENT OF CANADIAN LOANS.

         (a)      Each Canadian Borrower shall repay to each Canadian Lender on
the Maturity Date the aggregate principal amount of its Canadian Committed Loans
and all other Canadian Obligations owing to such Lender outstanding on such
date.

         (b)      The applicable Canadian Borrower shall repay each Canadian Bid
Loan made to it on the last day of the Interest Period in respect thereof.

         3.08     BANKERS' ACCEPTANCES.

         (a)      Creation of Bankers' Acceptances. Upon receipt of a Canadian
Committed Borrowing Notice requesting purchase or acceptance of Bankers'
Acceptances, and subject to the provisions of this Agreement, each Canadian
Lender shall accept, in accordance with its Canadian Pro Rata Share of the
requested Canadian Committed Borrowing from time to time such Bankers'
Acceptances as the applicable Canadian Borrower shall request.

         (b)      Terms of Acceptance by the Canadian Lenders.

                  (i)      Delivery and Payment. Subject to Sections 3.08(c) and
         3.08(d) and only if a valid appointment pursuant to Section 3.08(b)(v)
         is not in place, the Canadian Borrowers shall pre-sign and deliver to
         each Canadian Lender bankers' acceptance drafts in sufficient quantity
         to meet the their requirements for anticipated Canadian Committed
         Borrowings by way of Bankers' Acceptances. Each Canadian Borrower
         shall, at its option, provide for payment to Administrative Agent for
         the benefit of Canadian 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 Canadian Committed Borrowing in accordance with this Agreement,
         or through a combination thereof. Each Canadian Borrower waives
         presentment for payment of Bankers' Acceptances by Canadian Lenders and
         shall not claim from Canadian Lenders any days of grace for the payment
         at maturity of Bankers' Acceptances. Any amount owing by a Canadian
         Borrower in respect of any Bankers' Acceptance which is not paid in
         accordance with the foregoing, shall, as and from the

                                                          DEVON CREDIT AGREEMENT

                                       71
<PAGE>

         date on which such Bankers' Acceptance matures, be deemed to be
         outstanding hereunder as a Canadian Prime Rate Loan owing by such
         Canadian Borrower.

                  (ii)     No Liability. Administrative Agent and Canadian
         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 Administrative Agent or a Canadian Lender failing to use
         the same standard of care in the custody of such bankers' acceptance
         drafts as Administrative Agent or such Canadian Lender use in the
         custody of their own property of a similar nature.

                  (iii)    Bankers' Acceptances Purchased by Canadian Lenders.
         Where a Canadian Borrower so elects in the Canadian Committed Borrowing
         Notice, each Canadian Lender shall purchase Bankers' Acceptances
         accepted by it for an amount equal to the Canadian Discount Proceeds.

                  (iv)     Marketing. Where a Canadian Borrower so elects in the
         Canadian Committed Borrowing Notice, it shall be responsible for, and
         shall make its own arrangements with respect to, the marketing of
         Bankers' Acceptances, except for Bankers' Acceptances accepted by
         Canadian Lenders ("Old System Issuers") who are not able to issue
         Bankers' Acceptances as depository bills under the Depository Bills and
         Notes Act (Canada), which Bankers' Acceptances shall in all instances
         be purchased by such Old System Issuer.

                  (v)      Power of Attorney. To facilitate the procedures
         contemplated in this Agreement, each Canadian Borrower appoints each
         Canadian 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 Lender for Bankers' Acceptances denominated
         in Canadian Dollars. Each Bankers' Acceptance executed and delivered by
         a Canadian 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 Responsible Officer of such Canadian Borrower. The foregoing
         appointment shall cease to be effective, in respect of any Canadian
         Lender regarding such Canadian Borrower, three Business Days following
         receipt by such Canadian Lender of a written notice from such Canadian
         Borrower revoking such appointment (which notice shall be copied to the
         Administrative Agent); provided that any such revocation shall not
         affect Bankers' Acceptances previously executed and delivered by such
         Canadian Lender pursuant to such appointment.

                  (vi)     Market. If the Canadian Required Lenders determine,
         which determination shall be final conclusive and binding on the
         Canadian Borrowers, that there does not exist at the applicable time a
         normal market in Canada for the purchase and sale of Bankers'
         Acceptances, the Administrative Agent shall so notify the Canadian
         Borrowers, and the Canadian Lenders' obligation to accept Bankers'
         Acceptances under this Agreement shall be suspended until such time as
         the Administrative Agent (upon the instruction of the Canadian Required
         Lenders) revokes such notice. During any such

                                                          DEVON CREDIT AGREEMENT

                                       72
<PAGE>

         suspension, a request for a Bankers' Acceptance will be deemed to be a
         request for a Canadian Prime Rate Committed Loan.

                  (vii)    Pro-Rata Treatment of Canadian Borrowings.

                           (A)      In the event it is not practicable to
                  allocate Bankers' Acceptances to each Canadian Lender such
                  that the aggregate amount of Bankers' Acceptances required to
                  be purchased by such Canadian Lender hereunder is in a whole
                  multiple of C$100,000, the Administrative Agent is authorized
                  by each Canadian Borrower and each Canadian Lender to make
                  such allocation as the Administrative 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
                  Administrative Agent may allocate (on a basis considered by it
                  to be equitable) the excess of such Bankers' Acceptances over
                  the next lowest whole multiple of C$100,000 to one Canadian
                  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 Canadian Committed Borrowings by
                  way of Bankers' Acceptances of a Canadian Lender exceed such
                  Canadian Lender's Pro Rata Share of the aggregate Canadian
                  Committed Borrowings by way of Bankers' Acceptances by more
                  than C$100,000 as a result of such exercise of discretion by
                  the Administrative Agent.

                           (B)      If during the term of any Bankers'
                  Acceptance accepted by a Canadian Lender hereunder the
                  Canadian Stamping Fee Rate changes as a result of a change in
                  the Applicable Rate or an Event of Default occurs and is
                  continuing, the fee paid to such Canadian Lender by the
                  applicable Canadian Borrower pursuant to Section 4.02 (in this
                  paragraph called the "Initial Fee") with respect to such
                  Bankers' Acceptance shall be recalculated based upon such
                  change in the Canadian Stamping Fee Rate 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 the applicable Canadian
                  Borrower shall pay to such Canadian 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 the applicable Canadian
                  Borrower to such Canadian Lender.

         (c)      General Procedures for Bankers' Acceptances.

                  (i)      Notice. Each Canadian Borrower may in a Canadian
         Committed Borrowing Notice (which notice must be received by the
         Administrative Agent not later than 11:00 a.m. one Business Day prior
         to the date of the requested Canadian Borrowing by way of Bankers'
         Acceptances) request a Canadian Borrowing by way of Bankers'
         Acceptances. If such Canadian Borrower is responsible for marketing of
         such Bankers' Acceptances under Section 3.08(b)(iv), such Canadian
         Borrower by subsequent notice to

                                                          DEVON CREDIT AGREEMENT

                                       73
<PAGE>

         Administrative Agent by 11:00 a.m. on the day of the requested Canadian
         Borrowing by way of Bankers' Acceptances shall provide Administrative
         Agent (which shall in turn promptly notify each Canadian 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 Lender is to be made against delivery to
         each Canadian Lender of the applicable discount proceeds. Such discount
         proceeds less the fee calculated in accordance with Section 4.02(c)
         shall promptly be delivered to the Administrative Agent. Any telephone
         advice given under this Section shall be subject to Section 3.02 and
         shall be confirmed by a written notice of the Canadian Borrower to
         Administrative Agent prior to 2:00 p.m. on the same day.

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

                  (iii)    Conversion from Canadian Prime Rate Loans. In the
         case of a conversion from a Canadian Prime Rate Committed Loan into a
         Canadian Committed Borrowing by way of Bankers' Acceptances to be
         accepted by a Canadian Lender pursuant to Sections 3.08(a), (b) and
         (c), such Canadian 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 owing by such Canadian Borrower being
         converted, shall retain for its own account the Canadian 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 Administrative
         Agent for the benefit of Canadian Lenders an amount equal to the
         difference between the aggregate principal amount of the Canadian Prime
         Rate Loans owing by the applicable Canadian Borrower being converted
         owing to the Canadian Lenders and the aggregate Canadian Discount
         Proceeds of such Bankers' Acceptances.

                  (iv)     Conversions to Canadian Prime Rate Loans. In the case
         of a conversion of a Canadian Committed Borrowing by way of Bankers'
         Acceptances into Canadian Prime Rate Loan, each Canadian Lender, in
         order to satisfy the liability of the 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 such Canadian Borrower provides for payment to
         Administrative Agent for the benefit of Canadian Lenders of the face
         amount of the maturing Bankers' Acceptance in some other manner
         acceptable to Canadian Lenders, including conversion to another Type of
         Canadian Borrowing.

<PAGE>

                  (v)      Authorization. Each Canadian Borrower hereby
         authorizes each Canadian 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 the applicable Canadian Borrower pursuant to Sections 3.01
         and 3.02, as applicable.

                  (vi)     Depository Notes. The parties agree that in the
         administering of Bankers' Acceptances, each Canadian 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 Section 3.02 be deemed
         amended to the extent necessary to comply with the requirements of such
         debt clearing services.

         (d)      Execution of Bankers' Acceptances. The signatures of any
authorized signatory on Bankers' Acceptances may, at the option of the
applicable Canadian Borrower, be reproduced in facsimile and such Bankers'
Acceptances bearing such facsimile signatures shall be binding on the applicable
Canadian Borrower 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
the applicable Canadian Borrower 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 such Canadian Borrower.

         (e)      Escrowed Funds. Upon the occurrence of an Event of Default and
an acceleration of the Canadian Committed Loans under Section 10.02 or upon a
prepayment permitted under Section 3.06, each Canadian Borrower shall forthwith
pay to Administrative Agent for deposit into an escrow account maintained by and
in the name of Administrative Agent for the benefit of Canadian Lenders in
accordance with their Canadian Pro Rata Shares an amount equal to the Canadian
Lenders' maximum potential liability (as determined by Administrative Agent)
under then outstanding Bankers' Acceptances for such Canadian Borrower (the
"Canadian Escrow Funds"). The Canadian Escrow Funds shall be held by
Administrative Agent for set-off against future amounts owing by such Canadian
Borrower in respect to such Bankers' Acceptances and pending such application
shall bear interest at the rate declared by Administrative 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 Canadian Escrow Funds, together with any accrued
interest to the date of release, shall be forthwith released to the applicable
Canadian Borrower.

         3.09     CURRENCY FLUCTUATIONS. Notwithstanding any other provision of
this Agreement, Administrative Agent shall have the right at any time and from
time to time to calculate the Total Canadian Outstandings at the US Dollar
Equivalent thereof in US Dollars for any purposes including making a
determination from time to time of the available undrawn portion of the
Aggregate Canadian Commitments. If following such calculation, Administrative
Agent determines that the Total Canadian Outstandings are greater than 105% of
the Aggregate

                                                          DEVON CREDIT AGREEMENT

                                       75
<PAGE>

Canadian Commitments at such time, then Administrative Agent shall so advise
each Canadian Borrower and such Canadian Borrower shall following such advice
repay, on the later of (a) five Business Days after such advice and (b) the
earlier of (i) the next Interest Payment Date for Canadian Prime Rate Loans,
(ii) the next Interest Payment Date for Canadian US Eurodollar Rate Committed
Loans or Canadian Eurodollar Rate Committed Loans, and (iii) the next maturity
date of any outstanding Bankers' Acceptance, an amount equal to the amount by
which the Total Canadian Outstandings exceeds the Aggregate Canadian
Commitments, together with all accrued interest on the amount so paid.

         3.10     CURRENCY CONVERSION AND CURRENCY INDEMNITY.

         (a)      Each Canadian Borrower shall make payment relative to any
Canadian Borrowings (other than Canadian Base Rate Committed Loans or Canadian
US Eurodollar Rate Committed Loans) or Canadian Letter of Credit denominated in
Canadian Dollars in Canadian Dollars and shall make payment relative to Canadian
US Base Rate Committed Loans, Canadian US Eurodollar Rate Committed Loans, and
Canadian Letters of Credit denominated in US Dollars, in US Dollars. If any
payment is received on account of any such Canadian Borrowings or Letter of
Credit in any currency (the "Other Currency") other than the Applicable Currency
(whether voluntarily, pursuant to any conversion of a Canadian Borrowing or
pursuant to an order or judgment or the enforcement thereof or the realization
of any security or the liquidation of a Canadian Borrower or otherwise
howsoever), such payment shall constitute a discharge of the liability of such
Canadian Borrower hereunder and under the other Loan Documents in respect
thereof only to the extent of the amount of the Applicable Currency which the
Administrative Agent or relevant Canadian Lenders 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 Canadian Dollars, 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 Canadian Borrower shall be obligated to pay the Administrative Agent or
Canadian Lenders any deficiency in accordance with Section 3.10(a). For the
foregoing purposes "rate of exchange" means the rate at which the Administrative
Agent or relevant Canadian Lenders, as applicable, in accordance with their
normal banking procedures are able on the relevant date to purchase Canadian
Dollars with the Judgment Currency after deducting any premium and costs of
exchange.

         (c)      If the Administrative Agent or any Canadian Lender receives
any payment or payments on account of the liability of a Canadian Borrower
hereunder pursuant to any judgment or order in any Other Currency, and the
amount of Canadian Dollars which the Administrative Agent or relevant Canadian
Lender 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 Canadian Dollars due in respect of such liabilities immediately
prior to such judgment or order, then such Canadian Borrower shall, within five
Business Days after demand, and such Canadian Borrower

                                       76
<PAGE>

hereby agrees to, indemnify and save Administrative Agent or such Canadian
Lender 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 Administrative Agent or the Lenders 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.
                     GENERAL PROVISIONS APPLICABLE TO SENIOR

<PAGE>

                  (i)      If any amount of principal of any Loan is not paid
         when due (without regard to any applicable grace periods), whether at
         stated maturity, by acceleration or otherwise, such amount shall
         thereafter bear interest at a fluctuating interest rate per annum at
         all times equal to the rate two percent (2%) above the rate that was
         applicable to such Loan before a principal payment on such Loan became
         past due, to the fullest extent permitted by applicable Laws.

                  (ii)     If any amount (other than principal of any Loan)
         payable by the applicable Borrower under any Loan Document is not paid
         when due (without regard to any applicable grace periods), whether at
         stated maturity, by acceleration or otherwise, then upon the request of
         (x) the US Required Lenders, in the case of a US Obligation, or (y) the
         Canadian Required Lenders, in the case of a Canadian Obligation, such
         amount shall thereafter bear interest at a fluctuating interest rate
         per annum at all times equal to, in the case of a US Obligation, the US
         Base Rate plus two percent (2%), and, in the case of a Canadian
         Obligation, the Canadian Prime Rate plus two percent (2%) to the
         fullest extent permitted by applicable Laws.

                  (iii)    Accrued and unpaid interest on past due amounts
         (including interest on past due interest) shall be due and payable upon
         demand.

         (c)      Interest on each Loan shall be due and payable in arrears on
each Interest Payment Date applicable thereto and at such other times as may be
specified herein. Interest hereunder shall be due and payable in accordance with
the terms hereof before and after judgment, and before and after the
commencement of any proceeding under any Debtor Relief Law.

         (d)      For the purposes of the Interest Act (Canada), whenever
interest payable pursuant to this Agreement with respect to the Canadian
Borrowings, Canadian L/C Obligations and other amounts payable hereunder or
under the other Loan Documents with respect thereto is calculated on the basis
of a period other than a calendar year (the "Relevant 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 Relevant Period.

         (e)      To the extent permitted by law, the provisions of the Judgment
Interest Act (Alberta) R.S.A. 2000 C.J-1 shall not apply to the Loan Documents
and are hereby expressly waived by Canadian Borrowers.

of deemed reinvestment of interest shall not apply to any interest calculation
under the Loan Documents with respect to the Canadian Borrowings, Canadian L/C
Obligations, Bankers' Acceptances and other amounts payable hereunder or under
the other Loan Documents with respect thereto, and the rates of interest
stipulated in this Agreement are intended to be nominal rates and not effective
rates or yields.

         4.02     FEES. In addition to certain fees described in subsections (i)
and (j) of Section 2.04 and subsections (i) and (j) of Section 3.04:

         (a)      Facility Fees.

                  (i)      The US Borrower shall pay to the Administrative Agent
         for the account of each Lender in accordance with its Pro Rata Share, a
         facility fee equal to the Applicable Rate times the actual daily amount
         of the Aggregate US Commitments (or, if the Aggregate US Commitments
         have terminated, on the Outstanding Amount of all US Committed Loans,
         US Swing Line Loans and US L/C Obligations), regardless of usage.

                  (ii)     Devon Canada shall pay to the Administrative Agent
         for the account of each Canadian Lender in accordance with its Pro Rata
         Share, a facility fee equal to the Applicable Rate times the actual
         daily amount of the Aggregate Canadian Commitments (or, if the
         Aggregate Canadian Commitments have terminated, on the Outstanding
         Amount of all Canadian Committed Loans, Canadian Swing Line Loans and
         Canadian L/C Obligations), regardless of usage.

                  (iii)    The facility fees shall accrue at all times during
         the Availability Period (and thereafter so long as any Committed Loans,
         Swing Line Loans or L/C Obligations remain outstanding), including at
         any time during which one or more of the conditions in Article VI is
         not met, and shall be due and payable quarterly in arrears on the first
         Business Day after the end of each March, June, September and December,
         commencing with the first such date to occur after the Closing Date,
         and on the Maturity Date (and, if applicable, thereafter on demand).
         The facility fees shall be calculated quarterly in arrears, and if
         there is any change in the Applicable Rate during any quarter, the
         actual daily amount shall be computed and multiplied by the Applicable
         Rate separately for each period during such quarter that such
         Applicable Rate was in effect.

         (b)      Utilization Fees.

                  (i)      The US Borrower shall pay to the Administrative Agent
         for the account of each Lender in accordance with its Pro Rata Share, a
         utilization fee equal to the Applicable Rate times the Total
         Outstandings on each day that the Total Outstandings exceed 50% of the
         actual daily amount of the Aggregate Commitments then in effect (or, if
         terminated, in effect immediately prior to such termination).

                  (ii)     The utilization fees shall accrue at all times during
         the Availability Period (and thereafter so long as any Committed Loans,
         Swing Line Loans or L/C Obligations remain outstanding), including at
         any time during which one or more of the conditions in Article VI is
         not met, and shall be due and payable quarterly in arrears on the first
         Business Day after the end of each March, June, September and December,
         commencing with the first such date to occur after the Closing Date,
         and on the Maturity Date (and, if applicable, thereafter on demand).
         The utilization fee shall be calculated quarterly in arrears, and if
         there is any change in the Applicable Rate during any quarter, the
         actual

                                                          DEVON CREDIT AGREEMENT

                                       79
<PAGE>

         daily amount shall be computed and multiplied by the Applicable Rate
         separately for each period during such quarter that such Applicable
         Rate was in effect.

         (c)      Canadian Stamping Fee. In consideration of each Canadian
Lender's commitment to accept Bankers' Acceptances under this Agreement, the
applicable Canadian Borrower will pay to Administrative Agent for the account of
each Canadian Lender the Canadian Stamping Fee Rate multiplied by the face
amount of each Bankers' Acceptance accepted by such Canadian Lender under this
Agreement calculated for the number of days in the term of such Bankers'
Acceptance. Such fee shall be due and payable on the date on which such Bankers'
Acceptances are accepted and if such Canadian Lender is purchasing such Bankers'
Acceptance, such fee shall be deducted from the Canadian Discount Proceeds paid
to the applicable Canadian Borrower.

         (d)      Other Fees. The Borrowers shall pay to the Joint Lead
Arrangers and the Administrative Agent for their own respective accounts fees in
the amounts and at the times specified in the Fee Letter. Such fees shall be
fully earned when paid and shall not be refundable for any reason whatsoever.

         4.03     COMPUTATION OF INTEREST AND FEES ON LOANS. All computations of
(a) interest for (i) US Base Rate Loans, (ii) Canadian Base Rate Committed
Loans, and (iii) Canadian Prime Rate Loans, and (b) stamping fees for Bankers'
Acceptances shall be made on the basis of a year of 365 or 366 days, as the case
may be, and actual days elapsed. All other computations of fees and interest on
Loans shall be made on the basis of a 360-day year and actual days elapsed
(which results in more fees or interest, as applicable, being paid than if
computed on the basis of a 365-day year). Interest shall accrue on each Loan for
the day on which the Loan is made, and shall not accrue on a Loan, or any
portion thereof, for the day on which the Loan or such portion is paid, provided
that any Loan that is repaid on the same day on which it is made shall, subject
to Section 4.05(a), bear interest for one day.

         4.04     EVIDENCE OF DEBT.

         (a)      The Credit Extensions made by each Lender shall be evidenced
by one or more accounts or records maintained with respect to each applicable
Borrower by such Lender and by the Administrative Agent in the ordinary course
of business. The accounts or records maintained by the Administrative Agent and
each Lender shall be conclusive absent manifest error of the amount of the
Credit Extensions made by the Lenders to the Borrowers and the interest and
payments thereon. Any failure so to record or any error in doing so shall not,
however, limit or otherwise affect the obligation of the Borrowers hereunder to
pay any amount owing with respect to the Obligations. In the event of any
conflict between the accounts and records maintained by any Lender and the
accounts and records of the Administrative Agent in respect of such matters, the
accounts and records of the Administrative Agent shall control in the absence of
manifest error. Upon the request of any Lender made through the Administrative
Agent, the applicable Borrower shall execute and deliver to such Lender (through
the Administrative Agent) a Note, which shall evidence such Lender's Loans in
addition to such accounts or records. Each Lender may attach schedules to its
Note and endorse thereon the date, Type (if applicable), amount and maturity of
its Loans and payments with respect thereto.

                                                          DEVON CREDIT AGREEMENT

                                       80
<PAGE>

         (b)      In addition to the accounts and records referred to in
subsection (a), each Lender and the Administrative Agent shall maintain in
accordance with its usual practice accounts or records evidencing the purchases
and sales by such Lender of participations in Letters of Credit and Swing Line
Loans. In the event of any conflict between the accounts and records maintained
by the Administrative Agent and the accounts and records of any Lender in
respect of such matters, the accounts and records of the Administrative Agent
shall control in the absence of manifest error.

         4.05     PAYMENTS GENERALLY.

         (a)      All payments to be made by any Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by any Borrower
hereunder shall be made to the Administrative Agent or in the case of Canadian
Borrowings or Canadian Letters of Credit to the Administrative Agent at the
Canadian Payment Office, for the account of the respective Lenders to which such
payment is owed, at the Administrative Agent's Office or the Canadian Payment
Office, as applicable, in the Applicable Currency, and in immediately available
funds not later than 2:00 p.m. on the date specified herein. The Administrative
Agent or the Administrative Agent's office, as applicable, will promptly
distribute to each applicable Lender its Pro Rata Share (or other applicable
share as provided herein) of such payment in like funds as received by wire
transfer to such Lender's Lending Office. All payments received by the
Administrative Agent after 2:00 p.m. shall be deemed received on the next
succeeding Business Day and any applicable interest or fee shall continue to
accrue.

         (b)      If any payment to be made by any Borrower shall come due on a
day other than a Business Day, payment shall be made on the next following
Business Day, and such extension of time shall be reflected in computing
interest or fees, as the case may be.

         (c)      Unless any Borrower or any Lender has notified the
Administrative Agent, prior to the date any payment is required to be made by it
to the Administrative Agent hereunder, that such Borrower or such Lender, as the
case may be, will not make such payment, the Administrative Agent may assume
that such Borrower or such Lender, as the case may be, has timely made such
payment and may (but shall not be so required to), in reliance thereon, make
available a corresponding amount to the Person entitled thereto. If and to the
extent that such payment was not in fact made to the Administrative Agent in
immediately available funds, then:

                  (i)      if any Borrower failed to make such payment, each
         applicable Lender shall forthwith on demand repay to the Administrative
         Agent the portion of such assumed payment that was made available to
         such Lender in immediately available funds, together with interest
         thereon in respect of each day from and including the date such amount
         was made available by the Administrative Agent to such Lender to the
         date such amount is repaid to the Administrative Agent in immediately
         available funds at the Federal Funds Rate (or in the case of the
         Canadian Loans or Canadian Letters of Credit, the Canadian Prime Rate)
         from time to time in effect; and

                                                          DEVON CREDIT AGREEMENT

                                       81
<PAGE>

                  (ii)     if any Lender failed to make such payment, such
         Lender shall forthwith on demand pay to the Administrative Agent the
         amount thereof in immediately available funds, together with interest
         thereon for the period from the date such amount was made available by
         the Administrative Agent to the applicable Borrower to the date such
         amount is recovered by the Administrative Agent (the "Compensation
         Period") at a rate per annum equal to the Federal Funds Rate from time
         to time in effect. If such Lender pays such amount to the
         Administrative Agent, then such amount shall constitute such Lender's
         Committed Loan or Bid Loan, as the case may be, included in the
         applicable Borrowing. If such Lender does not pay such amount forthwith
         upon the Administrative Agent's demand therefor, the Administrative
         Agent may make a demand therefor upon the applicable Borrower, and such
         Borrower shall pay such amount to the Administrative Agent, together
         with interest thereon for the Compensation Period at a rate per annum
         equal to the rate of interest applicable to the applicable Borrowing.
         Nothing herein shall be deemed to relieve any Lender from its
         obligation to fulfill its Commitment or to prejudice any rights which
         the Administrative Agent or any Borrower may have against any Lender as
         a result of any default by such Lender hereunder.

         A notice of the Administrative Agent to any Lender or any Borrower with
respect to any amount owing under this subsection (c) shall be conclusive,
absent manifest error.

         (d)      If any Lender makes available to the Administrative Agent
funds for any Loan to be made by such Lender as provided in the foregoing
provisions of this Article IV, and such funds are not made available to the
applicable Borrower by the Administrative Agent because the conditions to the
applicable Credit Extension set forth in Article VI are not satisfied or waived
in accordance with the terms hereof, the Administrative Agent shall return such
funds (in like funds as received from such Lender) to such Lender, without
interest.

         (e)      The obligations of the Lenders hereunder to make US Committed
Loans and to fund participations in US Letters of Credit and US Swing Line Loans
are several and not joint. The failure of any Lender to make any US Committed
Loan or to fund any such participation on any date required hereunder shall not
relieve any other Lender of its corresponding obligation to do so on such date,
and no Lender shall be responsible for the failure of any other Lender to so
make its US Committed Loan or purchase its participation.

         (f)      The obligations of the Canadian Lenders hereunder to make
Canadian Committed Loans, to accept or purchase Bankers' Acceptances, and to
fund participations in Canadian Letters of Credit and Canadian Swing Line Loans
are several and not joint. The failure of any Canadian Lender to make any
Canadian Committed Loan, to accept or purchase any Bankers' Acceptance, or to
fund any such participation on any date required hereunder shall not relieve any
other Canadian Lender of its corresponding obligation to do so on such date, and
no Canadian Lender shall be responsible for the failure of any other Canadian
Lender to so make its Canadian Committed Loan or purchase its participation.

         (g)      Nothing herein shall be deemed to obligate any Lender to
obtain the funds for any Loan in any particular place or manner or to constitute
a representation by any Lender that it has obtained or will obtain the funds for
any Loan in any particular place or manner.

         4.06     SHARING OF PAYMENTS.

         (a)      If, other than as expressly provided elsewhere herein, any
Lender shall obtain on account of the US Committed Loans made by it, or the
participations in US L/C Obligations or in US Swing Line Loans held by it, any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder) thereof, such Lender shall immediately (i) notify the
Administrative Agent of such fact, and (ii) purchase from the other Lenders such
participations in the US Committed Loans made by them and/or such
subparticipations in the participations in US L/C Obligations or US Swing Line
Loans held by them, as the case may be, as shall be necessary to cause such
purchasing Lender to share the excess payment in respect of such US Committed
Loans or such participations, as the case may be, pro rata with each of them;
provided, however, that if all or any portion of such excess payment is
thereafter recovered from the applicable purchasing Lender under any of the
circumstances described in Section 12.07 (including pursuant to any settlement
entered into by the purchasing Lender in its discretion), such purchase shall to
that extent be rescinded and each other applicable Lender shall repay to the
purchasing Lender the purchase price paid therefor, together with an amount
equal to such paying Lender's ratable share (according to the proportion of (i)
the amount of such paying Lender's required repayment to (ii) the total amount
so recovered from the purchasing Lender) of any interest or other amount paid or
payable by the purchasing Lender in respect of the total amount so recovered,
without further interest thereon. The US Borrower agrees that any Lender so
purchasing a participation from the other Lender may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off, but subject to Section 12.10) with respect to such participation as
fully as if such Lender were the direct creditor of the US Borrower in the
amount of such participation. The Administrative Agent will keep records (which
shall be conclusive and binding in the absence of manifest error) of
participations purchased under this subsection and will in each case notify the
applicable Lenders following any such purchases or repayments. Each Lender that
purchases a participation pursuant to this subsection shall from and after such
purchase have the right to give all notices, requests, demands, directions and
other communications under this Agreement with respect to the portion of the US
Obligations purchased to the same extent as though the purchasing Lender were
the original owner of the US Obligations purchased.

         (b)      If, other than as expressly provided elsewhere herein, any
Canadian Lender shall obtain on account of the Canadian Committed Loans made by
it, the Bankers' Acceptances accepted by it, or the participations in Canadian
L/C Obligations or in Canadian Swing Line Loans held by it, any payment (whether
voluntary, involuntary, through the exercise of any right of set-off, or
otherwise) in excess of its ratable share (or other share contemplated
hereunder) thereof, such Canadian Lender shall immediately (i) notify the
Administrative Agent of such fact, and (ii) purchase from the other Canadian
Lenders such participations in the Canadian Committed Loans and Bankers'
Acceptances made by them and/or such subparticipations in the participations in
Canadian L/C Obligations or Canadian Swing Line Loans held by them, as the case
may be, as shall be necessary to cause such purchasing Canadian Lender to share
the excess payment in respect of such Canadian Committed Loans and Bankers'
Acceptances or such participations, as the case may be, pro rata with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the applicable purchasing

<PAGE>

Canadian Lender under any of the circumstances described in Section 12.07
(including pursuant to any settlement entered into by the purchasing Canadian
Lender in its discretion), such purchase shall to that extent be rescinded and
each other applicable Canadian Lender shall repay to the purchasing Canadian
Lender the purchase price paid therefor, together with an amount equal to such
paying Canadian Lender's ratable share (according to the proportion of (i) the
amount of such paying Canadian Lender's required repayment to (ii) the total
amount so recovered from the purchasing Canadian Lender) of any interest or
other amount paid or payable by the purchasing Canadian Lender in respect of the
total amount so recovered, without further interest thereon. The Canadian
Borrowers agree that any Canadian Lender so purchasing a participation from
another Canadian Lender may, to the fullest extent permitted by law, exercise
all its rights of payment (including the right of set-off, but subject to
Section 12.10) with respect to such participation as fully as if such Canadian
Lender were the direct creditor of the applicable Canadian Borrower in the
amount of such participation. The Administrative Agent will keep records (which
shall be conclusive and binding in the absence of manifest error) of
participations purchased under this subsection and will in each case notify the
applicable Canadian Lenders following any such purchases or repayments. Each
Canadian Lender that purchases a participation pursuant to this subsection shall
from and after such purchase have the right to give all notices, requests,
demands, directions and other communications under this Agreement with respect
to the portion of the Canadian Obligations purchased to the same extent as
though the purchasing Canadian Lender were the original owner of the Canadian
Obligations purchased.

         4.07     CANADIAN REALLOCATION OF THE COMMITMENTS The Borrowers may by
notice to the Administrative Agent reallocate a portion of the Aggregate
Commitments specified therein as part of the Aggregate Canadian Commitments;
provided that (i) any such notice shall be received by the Administrative Agent
not later than 11:00 a.m. five Business Days prior to the date such reallocation
shall become effective, (ii) any such reallocation shall be in an aggregate
amount of US $50,000,000 if the amount of the Aggregate Canadian Commitments at
the time of such reallocation is zero, and otherwise in an aggregate amount of
US $10,000,000 or in each case any whole multiple of US $1,000,000 in excess
thereof, or shall be a reallocation to zero, (iii) after any such reallocation,
the amount of the Aggregate Canadian Commitments shall be equal to or greater
than US $50,000,000 or shall be zero, (iv) the Borrowers shall not reallocate
any portion of the Aggregate Commitments if, after giving effect thereto and to
any concurrent prepayments hereunder (a) the Total Outstandings would exceed the
Aggregate Commitments, (b) the Total Canadian Outstandings would exceed the
Aggregate Canadian Commitments, (c) the sum of any Lender's outstanding US
Committed Loans plus such Lender's Pro Rata Share of outstanding US L/C
Obligations and US Swing Line Loans would exceed such Lender's US Commitment; or
(d) the sum of any Canadian Lender's outstanding Canadian Committed Loans and
Bankers' Acceptances plus such Canadian Lender's Pro Rata Share of outstanding
Canadian L/C Obligations and Canadian Swing Line Loans would exceed such
Canadian Lender's Canadian Commitment, and (v) the Borrowers shall make not more
than four reallocations of the Commitments in any calendar year. The
Administrative Agent will promptly notify the Lenders or their Canadian branches
or affiliates with Canadian Commitments of any such notice of reallocation of
the Commitments and the amount of their respective Canadian Commitments, and
shall notify all Lenders of the Commitments and the Aggregate Canadian
Commitments upon the effectiveness of such reallocation.

         4.08     EXTENSION OF MATURITY DATE.

         (a)      Not earlier than 60 days prior to, nor later than 45 days
prior to, each anniversary of the Closing Date, the US Borrower may, upon notice
to the Administrative Agent (which shall promptly notify the Lenders), request a
one-year extension of the Maturity Date then in effect. Within 30 days of
delivery of such notice, each Lender shall notify the Administrative Agent
whether or not it consents to such extension (which consent may be given or
withheld in such Lender's sole and absolute discretion). Any Lender not
responding within the above time period shall be deemed not to have consented to
such extension. The Administrative Agent shall promptly notify the US Borrower
and the Lenders of the Lenders' responses.

         (b)      The Maturity Date shall be extended only if Lenders holding at
least 75% of the Aggregate Commitments (calculated excluding Defaulting Lenders
and prior to giving effect to any replacements of Lenders permitted herein) (the
"Consenting Lenders") have consented thereto. If so extended, the Maturity Date,
as to the Consenting Lenders, shall be extended to the same date in the
following year, effective as of the Maturity Date then in effect (such existing
Maturity Date being the "Extension Effective Date"). The Administrative Agent
and the US Borrower shall promptly confirm to the Lenders such extension and the
Extension Effective Date. As a condition precedent to such extension, the US
Borrower shall deliver to the Administrative Agent a certificate of each Loan
Party dated as of the Extension Effective Date (in sufficient copies for each
Lender) signed by a Responsible Officer of such Loan Party (i) certifying and
attaching the resolutions adopted by such Loan Party approving or consenting to
such extension and (ii) in the case of each Borrower, certifying that, (A)
before and after giving effect to such extension, the representations and
warranties contained in Article VII and the other Loan Documents made by it are
true and correct in all material respects on and as of the Extension Effective
Date, except to the extent that such representations and warranties specifically
refer to an earlier date, (B) before and after giving effect to such extension
no Default exists or will exist, and (C) no event has occurred since the date of
the most recent audited financial statements of the US Borrower delivered
pursuant to Section 8.02(a) that has had, or could reasonably be expected to
have, a Material Adverse Effect. The US Borrower shall prepay any US Committed
Loans outstanding on the Extension Effective Date (and pay any additional
amounts required pursuant to Section 5.05) to the extent necessary to keep
outstanding US Committed Loans ratable with any revised and new Pro Rata Shares
of all the Lenders effective as of the Extension Effective Date. Each Canadian
Borrower shall prepay any Canadian Committed Loans owing by it outstanding on
the Extension Effective Date (and pay any additional amounts required pursuant
to Section 5.05) to the extent necessary to keep outstanding Canadian Committed
Loans ratable with any revised and new Pro Rata Shares of all the Canadian
Lenders effective as of the Extension Effective Date.

         (c)      If any Lender does not consent to the extension of the
Maturity Date as provided in this Section 4.08, the US Borrower shall have the
right to replace such Lender in accordance with Section 12.17.

         (d)      This Section shall supersede any provisions in Section 4.06 or
12.01 to the contrary.

         4.09     INCREASE IN COMMITMENTS.

         (a)      Provided there exists no Default, upon notice to the
Administrative Agent (which shall promptly notify the Lenders), the US Borrower
may, from time to time, request an increase in the Aggregate Commitments to an
amount not exceeding US $2,000,000,000; provided that (i) any such request for
an increase shall be in a minimum amount of US $50,000,000, and (ii) the US
Borrower may make a maximum of two such requests per calendar year. At the time
of sending such notice, the US Borrower (in consultation with the Administrative
Agent) shall specify the time period within which each Lender is requested to
respond (which shall in no event be less than ten Business Days from the date of
delivery of such notice to the Lenders). Each Lender shall notify the
Administrative Agent within such time period whether or not it agrees to
increase its Commitment and, if so, whether by an amount equal to, greater than,
or less than its Pro Rata Share of such requested increase. Any Lender not
responding within such time period shall be deemed to have declined to increase
its Commitment. The Administrative Agent shall notify the US Borrower and each
Lender of the Lenders' responses to each request made hereunder. To achieve the
full amount of a requested increase, the US Borrower may also invite additional
Eligible Assignees to become Lenders pursuant to a joinder agreement in form and
substance reasonably satisfactory to the Administrative Agent and its counsel.

         (b)      If the Aggregate Commitments are increased in accordance with
this Section, the Administrative Agent and the US Borrower shall determine the
effective date (the "Increase Effective Date") and the final allocation of such
increase. The Administrative Agent shall promptly notify the US Borrower and the
Lenders of the final allocation of such increase and the Increase Effective
Date. As a condition precedent to such increase, the US Borrower shall deliver
to the Administrative Agent a certificate of each Loan Party dated as of the
Increase Effective Date (in sufficient copies for each Lender) signed by a
Responsible Officer of such Loan Party (i) certifying and attaching the
resolutions adopted by such Loan Party approving or consenting to such increase,
and (ii) in the case of each Borrower, certifying that, before and after giving
effect to such increase, (A) the representations and warranties contained in
Article VII and the other Loan Documents made by it are true and correct in all
material respects on and as of the Extension Effective Date, except to the
extent that such representations and warranties specifically refer to an earlier
date, in which case they are true and correct in all material respects as of
such earlier date, and (B) no Default exists. The US Borrower shall prepay any
US Committed Loans outstanding on the Increase Effective Date (and pay any
additional amounts required pursuant to Section 5.05) to the extent necessary to
keep the outstanding US Committed Loans ratable with any revised Pro Rata Shares
arising from any nonratable increase in the US Commitments under this Section.
Each Canadian Borrower shall prepay any Canadian Committed Loans owing by it and
outstanding on the Increase Effective Date (and pay any additional amounts
required pursuant to Section 5.05) to the extent necessary to keep the
outstanding Canadian Committed Loans ratable with any revised Pro Rata Shares
arising from any nonratable increase in the Canadian Commitments under this
Section.

         (c)      This Section shall supersede any provisions in Sections 4.06
or 12.01 to the contrary.

         4.10     TERMINATION OR REDUCTION OF COMMITMENTS. The US Borrower may,
upon notice to the Administrative Agent, terminate the Aggregate Commitments
(including the Aggregate Canadian Commitments), or from time to time permanently
reduce the Aggregate Commitments (and proportionately reduce the Aggregate
Canadian Commitments); provided that (i) any such notice shall be received by
the Administrative Agent not later than 11:00 a.m. two Business Days prior to
the date of termination or reduction, (ii) any such partial reduction shall be
in an aggregate amount of US $10,000,000 or any whole multiple of US $1,000,000
in excess thereof, (iii) the US Borrower shall not terminate or reduce the
Aggregate Commitments (and the Aggregate Canadian Commitments, if applicable)
if, after giving effect thereto and to any concurrent prepayments hereunder, (1)
the Total Outstandings would exceed the Aggregate Commitments, (2) the Total US
Outstandings would exceed the Aggregate US Commitments, or (3) the Total
Canadian Outstandings would exceed the Aggregate Canadian Commitments, and (iv)
if, after giving effect to any reduction of the Aggregate Commitments, the US
Letter of Credit Sublimit or the US Swing Line Sublimit exceeds the amount of
the Aggregate US Commitments or the Canadian Letter of Credit Sublimit or the
Canadian Swing Line Sublimit exceeds the Aggregate Canadian Commitments, such
Sublimits shall be automatically reduced by the amount of such excess. The
Administrative Agent will promptly notify the Lenders of any such notice of
termination or reduction of the Aggregate Commitments. Any reduction of the
Aggregate Commitments shall be applied to the US Commitment of each Lender
according to such Lender's Pro Rata Share. All fees accrued until the effective
date of any termination of the Aggregate Commitments shall be paid on the
effective date of such termination.

                                   ARTICLE V.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

         5.01     TAXES.

         (a)      Any and all payments by any Borrower to or for the account of
the Administrative Agent or any Lender under any Loan Document shall be made
free and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of the
Administrative Agent and each Lender, taxes imposed on or measured by its
overall net income, and franchise taxes imposed on it (in lieu of net income
taxes), by the jurisdiction (or any political subdivision thereof) under the
Laws of which the Administrative Agent or such Lender, as the case may be, is
organized or maintains a lending office (all such non-excluded taxes, duties,
levies, imposts, deductions, assessments, fees, withholdings or similar charges,
and liabilities being hereinafter referred to as "Taxes"). If any Borrower shall
be required by any Laws to deduct any Taxes from or in respect of any sum
payable under any Loan Document to the Administrative Agent or any Lender, (i)
subject to compliance by such Lender with Sections 12.16 and 5.01(g), as
applicable, 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), each of the Administrative Agent and such Lender
receives an amount equal to the sum it would have received had no such
deductions been made, (ii) such Borrower shall make such deductions, (iii) such
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable Laws, and (iv) within 30 days

                                                          DEVON CREDIT AGREEMENT

                                       87
<PAGE>

after the date of such payment, such Borrower shall furnish to the
Administrative Agent (which shall forward the same to such Lender) the original
or a certified copy of a receipt evidencing payment thereof.

         (b)      In addition, the Borrowers agree to pay any and all present or
future stamp, court or documentary taxes and any other excise or property taxes
or charges or similar levies which arise from any payment made under any Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "Other Taxes").

         (c)      If any Borrower shall be required to deduct or pay any Taxes
or Other Taxes from or in respect of any sum payable under any Loan Document to
the Administrative Agent or any Lender, such Borrower shall also pay to the
Administrative Agent or to such Lender, as the case may be, at the time interest
is paid, such additional amount that the Administrative Agent or such Lender
specifies is necessary to preserve the after-tax yield (after factoring in all
taxes, including taxes imposed on or measured by net income) that the
Administrative Agent or such Lender would have received if such Taxes or Other
Taxes had not been imposed.

         (d)      Subject to compliance by such Lender with Sections 12.16
and 5.01(g), as applicable, each Borrower agrees to indemnify the Administrative
Agent and each Lender for (i) the full amount of Taxes and Other Taxes
(including any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section) paid by the Administrative Agent and such
Lender, (ii) amounts payable under Section 5.01(c) and (iii) any liability
(including additions to tax, penalties, interest and expenses) arising therefrom
or with respect thereto, in each case whether or not such Taxes or Other Taxes
were correctly or legally imposed or asserted by the relevant Governmental
Authority; provided that the Borrowers shall not be obligated to indemnify the
Administrative Agent or any Lender pursuant to this Section 5.01(d) in respect
of penalties, interest or expenses arising from or with respect to such Taxes or
Other Taxes if such penalties, interest or expenses are attributable to the
gross negligence or willful misconduct of the Person seeking indemnification.
Any payment required to be made under this Section 5.01(d) shall be made within
30 days after the date such Lender or the Administrative Agent makes a demand
therefor.

         (e)      In the event that any Lender or the Administrative Agent
receives a refund in respect of Taxes or Other Taxes as to which it has been
paid additional amounts by any Borrower pursuant to clause (a) or (b) above or
indemnified by any Borrower pursuant to clause (d) and such Lender or
Administrative Agent, as applicable, reasonably determines that such refund is
attributable to such additional amounts or indemnification, then such Lender or
Administrative Agent, as applicable, shall promptly notify the Administrative
Agent and the applicable Borrower and shall within 30 Business Days remit to
such Borrower an amount as such Lender or Administrative Agent, as applicable,
determines to be the proportion of the refunded amount as will leave it, after
such remittance, in no better or worse position than it would have been if the
Taxes or Other Taxes had not been imposed and the corresponding additional
amounts or indemnification payment not been made; provided, that such Borrower,
upon request by the Administrative Agent or such Lender, shall promptly return
such refund to the Administrative Agent or such Lender, as the case may be, in
the event that the Administrative

                                                          DEVON CREDIT AGREEMENT

                                       88
<PAGE>

Agent or such Lender is required to repay such refund to the relevant
Governmental Authority. Nothing contained in this Section 5.01(e) shall require
the Administrative Agent or any Lender to make available to any Borrower any of
its tax returns or any other information relating to its taxes that it deems to
be confidential.

         (f)      If requested by any Borrower, any Lender claiming any
indemnity or additional amounts payable pursuant to this Section 5.01 shall use
its reasonable efforts (consistent with its reasonable internal policy and legal
and regulatory restrictions) to change the jurisdiction of its designated
Lending Office if the making of such a change would avoid the need for, or
reduce the amount of, any such indemnity or additional amounts which would be
payable or may thereafter accrue; provided, that such designation would not, in
the sole judgment of such Lender exercised in good faith, be otherwise
disadvantageous to such Lender; provided, further, that nothing in this Section
5.01(f) shall adversely affect or postpone any of the obligations of any
Borrower or the rights of any Lender under this Agreement.

         (g)      Each Canadian Lender that is not a Canadian Resident Lender
shall deliver, or have its applicable lending office deliver, to the Canadian
Borrowers and the Administrative Agent on the date on which such Canadian Lender
or such applicable lending office becomes a Canadian Lender hereunder (whether
by way of becoming a successor Canadian Lender or otherwise), notice that the
Canadian Lender is not a Canadian Resident Lender. In addition, if there is any
change in such status, the applicable Canadian Lender shall provide notice of
such change promptly to the Canadian Borrowers and the Administrative Agent.
Notwithstanding any provision hereof to the contrary and for the avoidance of
doubt, it is acknowledged by the parties that there may be Canadian tax imposed
under Part XIII of the Income Tax Act (Canada) ("Canadian Withholding Tax") on
any payments as, on account or in lieu of payment of, or in satisfaction of,
interest and other fees paid by the Canadian Borrowers or the Administrative
Agent under the Canadian SubFacility (but, for greater certainty, excluding any
payments under the Guaranties) to persons who are not Canadian Resident Lenders
(such payments a "Taxable Payment"). The Canadian Borrowers shall have no
obligation to make any additional or increased payment under clause (a) or
clause (c) above, or to indemnify the Administrative Agent or a Canadian Lender
under clause (d) above, in respect of any Canadian Withholding Tax on a Taxable
Payment, and the Canadian Borrowers shall be entitled to deduct and remit to the
proper Canadian taxing authorities any such Canadian Withholding Tax from any
such Taxable Payments.

         5.02     ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund US
Dollar Eurodollar Rate Loans, or Canadian Dollar Eurodollar Rate Loans, as
applicable, or to determine or charge interest rates based upon the US Dollar
Eurodollar Rate or the Canadian Dollar Eurodollar Rate, then, on notice thereof
by such Lender to each applicable Borrower through the Administrative Agent, any
obligation of such Lender (a) to make or continue US Dollar Eurodollar Rate
Loans or Canadian US Eurodollar Rate Committed Loans, or (b) to convert (i) US
Base Rate Committed Loans to US Eurodollar Rate Committed Loans or (ii) Canadian
Prime Rate Committed Loans or Canadian Base Rate Committed Loans to Canadian
Eurodollar Rate Committed Loans or Canadian US Eurodollar Rate Committed Loans,
shall be suspended until such Lender notifies the Administrative Agent

                                                          DEVON CREDIT AGREEMENT

                                       89
<PAGE>

and each applicable Borrower that the circumstances giving rise to such
determination no longer exist. Upon receipt of such notice, each applicable
Borrower shall, upon demand from such Lender (with a copy to the Administrative
Agent), prepay or, if applicable, (a) convert all US Dollar Eurodollar Rate
Loans or Canadian US Eurodollar Rate Committed Loans of such Lender to US Base
Rate Loans, or Canadian Base Rate Committed Loans, as the case may be, and (b)
convert all Canadian Dollar Eurodollar Rate Loans of such Lender to Canadian
Prime Rate Committed Loans, either on the last day of the Interest Period
therefor, if such Lender may lawfully continue to maintain such US Dollar
Eurodollar Rate Loans or Canadian Dollar Eurodollar Rate Loans, as the case may
be, to such day, or immediately, if such Lender may not lawfully continue to
maintain such US Dollar Eurodollar Rate Loans or Canadian Eurodollar Rate Loans,
as the case may be. Upon any such prepayment or conversion, each applicable
Borrower shall also pay accrued interest on the amount so prepaid or converted.
Each Lender agrees to designate a different Lending Office if such designation
will avoid the need for such notice and will not, in the good faith judgment of
such Lender, otherwise be materially disadvantageous to such Lender.

         5.03     INABILITY TO DETERMINE RATES.

         (a)      If the US Required Lenders determine that for any reason
adequate and reasonable means do not exist for determining the US Dollar
Eurodollar Rate for any requested Interest Period with respect to a proposed US
Eurodollar Rate Committed Loan, or that the US Dollar Eurodollar Rate for any
requested Interest Period with respect to a proposed US Eurodollar Rate
Committed Loan does not adequately and fairly reflect the cost to such Lenders
of funding such Loan, the Administrative Agent will promptly so notify the US
Borrower and each Lender. Thereafter, the obligation of the Lenders to make or
maintain US Dollar Eurodollar Rate Loans shall be suspended until the
Administrative Agent (upon the instruction of the US Required Lenders) revokes
such notice. Upon receipt of such notice, the US Borrower may revoke any pending
request for a US Borrowing of, conversion to or continuation of US Eurodollar
Rate Committed Loans or, failing that, will be deemed to have converted such
request into a request for a US Committed Borrowing of US Base Rate Loans in the
amount specified therein.

         (b)      If the Canadian Required Lenders determine that for any reason
adequate and reasonable means do not exist for determining the US Dollar
Eurodollar Rate or the Canadian Dollar Eurodollar Rate for any requested
Interest Period with respect to a proposed Canadian Eurodollar Rate Committed
Loan, or that the US Dollar Eurodollar Rate or the Canadian Dollar Eurodollar
Rate for any requested Interest Period with respect to a proposed Canadian
Committed Loan does not adequately and fairly reflect the cost to such Canadian
Lenders of funding such Loan, the Administrative Agent will promptly so notify
each Canadian Borrower and each Canadian Lender. Thereafter, the obligation of
the Canadian Lenders to make or maintain Canadian Dollar Eurodollar Rate Loans
and Canadian US Eurodollar Rate Loans shall be suspended until the
Administrative Agent (upon the instruction of the Canadian Required Lenders)
revokes such notice. Upon receipt of such notice, any Canadian Borrower may
revoke any pending request for a Canadian Borrowing of, conversion to or
continuation of such Canadian Committed Loans or, failing that, will be deemed
to have converted such request into a

ON US DOLLAR EURODOLLAR RATE LOANS, CANADIAN DOLLAR EURODOLLAR RATE LOANS, AND
CANADIAN US EURODOLLAR RATE COMMITTED LOANS.

         (a)      If any Lender determines that as a result of a Change in Law,
or such Lender's compliance therewith, there shall be any increase in the cost
to such Lender of agreeing to make or making, funding or maintaining US DOLLAR
EURODOLLAR RATE LOANS, Canadian Dollar Eurodollar Rate Loans, or Canadian US
Eurodollar Rate Committed Loans or (as the case may be) issuing or participating
in Letters of Credit, or a reduction in the amount received or receivable by
such Lender in connection with any of the foregoing (excluding for purposes of
this subsection (a) any such increased costs or reduction in amount resulting
from (i) Taxes or Other Taxes (as to which Section 5.01 shall govern), (ii)
changes in the basis of taxation of, or in the rate or amount of taxes imposed
on or measured by reference to, overall net income or franchise taxes (in lieu
of net income taxes), or overall gross income by the United States or Canada or
any other foreign jurisdiction or any political subdivision of either thereof
under the Laws of which such Lender is organized or maintains a Lending Office,
and (iii) reserve requirements contemplated by Section 5.04(c)), then from time
to time within 20 days following delivery by such Lender of a certificate
described in Section 5.06 (with a copy of such demand to the Administrative
Agent), each applicable Borrower shall pay to such Lender such additional
amounts as will compensate such Lender for such increased cost or reduction.

         (b)      If any Lender determines that a Change in Law regarding
capital adequacy or compliance by such Lender (or its Lending Office) therewith,
has the effect of reducing the rate of return on the capital of such Lender or
any corporation controlling such Lender as a consequence of such Lender's
obligations hereunder (taking into consideration its policies with respect to
capital adequacy and such Lender's desired return on capital), then from time to
time upon demand of such Lender (with a copy of such demand to the
Administrative Agent), each applicable Borrower shall pay to such Lender such
additional amounts as will compensate such Lender for such reduction.

         (c)      The US Borrower shall pay to each Lender, and the applicable
Canadian Borrower shall pay to each Canadian Lender, as long as such Lender
shall be required to maintain reserves with respect to liabilities or assets
consisting of or including Eurocurrency funds or deposits (currently known as
"Eurocurrency liabilities"), additional interest on the unpaid principal amount
of each US Dollar Eurodollar Rate Loan or Canadian Dollar Eurodollar Rate Loan,
as applicable, equal to the actual costs of such reserves allocated to such Loan
by such Lender (as determined by such Lender in good faith, which determination
shall be conclusive), which shall be due and payable on each date on which
interest is payable on such Loan, provided the applicable Borrower shall have
received at least 15 days' prior notice (with a copy to the Administrative
Agent) of such additional interest from such Lender. If a Lender fails to give
notice 15 days prior to the relevant Interest Payment Date, such additional
interest shall be due and payable 15 days from receipt of such notice.

         5.05     COMPENSATION FOR LOSSES. Within 20 days following delivery by
any Lender of a certificate described in Section 5.06, upon demand of such
Lender (with a copy to the Administrative Agent) from time to time, each
applicable Borrower shall promptly compensate such Lender for and hold such
Lender harmless from any loss, cost or expense incurred by it as a result of:

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

         (b)      any failure by the applicable Borrower (for a reason other
than the failure of such Lender to make a Loan) to prepay, borrow, continue or
convert any Loan other than a US Base Rate Loan, a Canadian Prime Rate Loan or a
Canadian Base Rate Committed Loan, as the case may be, on the date or in the
amount notified by the applicable Borrower; or

         (c)      any assignment of a US Dollar Eurodollar Rate Loan or a
Canadian Dollar Eurodollar Rate Loan or a Canadian US Eurodollar Rate Committed
Loan, as the case may be, on a day other than the last day of the Interest
Period therefor as a result of a request by the applicable Borrower pursuant to
Section 12.17;

excluding any loss of anticipated profits but including any actual loss or
expense arising from the liquidation or reemployment of funds obtained by it to
maintain such Loan or from fees payable to terminate the deposits from which
such funds were obtained.

         5.06     MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION.

         A certificate of the Administrative Agent or any Lender claiming
compensation under this Article V and setting forth the additional amount or
amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, the Administrative Agent or such
Lender may use any reasonable averaging and attribution methods. The applicable
Borrower may reasonably request copies of documentation supporting such methods.

         Upon any Lender's making a claim for compensation under Section 5.01 or
5.04, the US Borrower may replace such Lender in accordance with Section 12.17.

         Notwithstanding any other provision of this Agreement to the contrary,
no Borrower shall be under any obligation to compensate the Administrative Agent
or any Lender under Sections 5.01, 5.04 or 5.05 with respect to any request to
be compensated for any losses, costs, expenses or other amounts relating to any
period prior to the date that is 180 days prior to such request if such Lender
or the Administrative Agent, as the case may be, knew of the circumstances
giving rise to such losses, costs, expenses or amounts.

         5.07     SURVIVAL. All of the Borrowers' obligations under this Article
V shall survive termination of the Aggregate Commitments and repayment of all
other Obligations hereunder.

                         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 with respect to the
following matters applicable to it and its Subsidiaries that, and the US
Borrower represents and warrants to each Lender with respect to all of the
following matters that:

         7.01     NO DEFAULT. No event has occurred and is continuing which
constitutes a Default.

         7.02     ORGANIZATION AND GOOD STANDING. Each Restricted Person 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
Restricted Person is duly qualified, in good standing, and authorized to do
business in all other jurisdictions within the United States or 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 Restricted
Person 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 or 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.

         7.03     AUTHORIZATION. Each Borrower has duly taken all action
necessary to authorize the execution and delivery by it of the 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. The
Borrowers are duly authorized to make Borrowings and request Letters of Credit
hereunder.

         7.04     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 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 result in the acceleration of any Indebtedness owed by any
Restricted Person which would reasonably be expected to have a Material Adverse
Effect, or 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 Governmental Authority 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

                                       95

failure to obtain such consent would not reasonably be expected to have a
Material Adverse Effect.

Documents when duly executed and delivered will be, legal, valid and binding
obligations of each Restricted Person which is a party hereto or thereto,

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 when taken together with all reports, statements, schedules and
other information included in filings made by the US Borrower and its
Subsidiaries with the SEC (collectively, "SEC Filings") 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
in the SEC Filings or a Disclosure Report to each Lender in writing which would
reasonably be expected to have a Material Adverse Effect.

         7.07     LITIGATION. Except as disclosed in the SEC Filings or in the
Disclosure Schedule or a Disclosure Report there are no actions, suits or legal,
equitable, arbitrative or administrative proceedings pending, or to the
knowledge of any Restricted Person threatened, against any Restricted Person
before any Governmental Authority 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 Governmental Authority against any
Restricted Person which would reasonably be expected to have a Material Adverse
Effect.

         7.08     ERISA PLANS AND LIABILITIES.

         All currently existing ERISA Plans and Multiemployer Plans are listed
in the Disclosure Schedule. Except as disclosed in the Disclosure Schedule, in
the SEC Filings or a Disclosure Report, no Termination Event when taken together
with all other Termination Events, would reasonably be expected to have a
Material Adverse Effect. Except as set forth in Schedule 7.08 or in the Annual
Report on Form 10K or the Quarterly Report on Form 10Q of US Borrower filed with
the SEC, (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 would be incurred by all ERISA Affiliates
upon their complete withdrawal from all Multiemployer Plans would not reasonably
be expected to exceed the Threshold Amount, 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 the Threshold Amount.

Disclosure Schedule, Restricted Persons 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; 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 no Restricted Person (and to the best knowledge of
Borrowers, 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.

         7.10     MATERIAL SUBSIDIARIES. As of the date hereof: US Borrower does
not have any Material Subsidiary except those listed in the Disclosure Schedule,
and US Borrower owns, directly or indirectly, the equity interest in each of its
Material Subsidiaries which is indicated in the Disclosure Schedule.

         7.11     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 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.

         7.12     GOVERNMENT REGULATION. No Restricted Person owing Obligations
(i) is a "holding company," or a "subsidiary company" of a "holding company," or
an "affiliate" of a holding company" or a "subsidiary company" of a "holding

Investment Company Act of 1940.

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

         7.14     MARGIN STOCK. No Borrower is engaged or will engage,
principally or as one of its important activities, in the business of purchasing
or carrying margin stock (within the

                                                          DEVON CREDIT AGREEMENT

         (f)      non-recourse Indebtedness as to which no Restricted Person

provided that in each case, the Devon Financing ULC Guaranties remain valid,
binding and enforceable obligations of Devon Financing ULC or, if any Devon

replaced, so long as no Restricted Subsidiary increases (except for the purpose
of paying any prepayment premium or any fees and expenses incurred in connection

         the District of Columbia, shall have non-credit enhanced, senior
         unsecured long-term Indebtedness rated "investment grade" by S&P or
         Moody's (or, in the event the US Borrower did not have non-credit
         enhanced, senior unsecured long-term Indebtedness rated "investment
         grade" by S&P or Moody's immediately preceding such transaction, such
         Person shall have non-credit enhanced, senior unsecured long-term
         Indebtedness that is not rated lower by S&P or Moody's than S&P's or
         Moody's ratings, respectively, of the US Borrower's non-credit
         enhanced, senior unsecured long-term Indebtedness immediately preceding
         such transaction), and shall expressly assume, by an agreement

Default or Event of Default shall have occurred and be continuing.

         9.04     FUNDAMENTAL CHANGES OF CANADIAN BORROWERS. No Canadian

         (a)      (i)      in the case of a merger or amalgamation, a Canadian
         Borrower is the surviving entity; or

                  (ii)     all Canadian Obligations of such Canadian Borrower
         shall have been paid in full and the obligations of the Canadian

         continuing from such merger or amalgamation of such Canadian Borrower
         or the Person which acquires by conveyance or transfer, or which
         leases, the properties and assets of such Canadian Borrower
         substantially as an entirety shall be a corporation, unlimited
         liability company, partnership or trust, shall be organized and
         existing under the laws of Canada or any province thereof, and shall
         assume by operation of law or expressly assume, by an agreement
         supplemental hereto, executed and delivered to the Administrative
         Agent, in form reasonably satisfactory to the Administrative Agent, the

favorable in any material respect to it than those which would have been
obtainable at the time in arm's-length dealing with Persons other than such
Affiliates, provided that such restriction shall not apply to transactions among
the US Borrower and its Subsidiaries (including such transactions among such
Subsidiaries).

to make Restricted Payments to such Borrower or otherwise to transfer property
to such Borrower, other than any limitation which would not be reasonably
expected to materially impair the ability of such Borrower to perform its
monetary obligations hereunder.

         9.07     FUNDED DEBT TO TOTAL CAPITALIZATION. The ratio of the US
Borrower's Consolidated Total Funded Debt to the US Borrower's Total
Capitalization will not exceed sixty-five percent (65%) at the end of any Fiscal
Quarter.

Securities in the Subordinated US Borrower Debentures and engaging in only those

its option to defer interest payments on the Subordinated US Borrower Debentures
rather than default on such interest payments. Devon Trust shall not redeem the
Devon Trust Securities prior to their stated maturity, and the US Borrower shall
not prepay or redeem the Subordinated the US Borrower Debentures prior to their
stated maturity, unless both immediately before and immediately after any such
proposed prepayment or redemption, the US

                         EVENTS OF DEFAULT AND REMEDIES

         10.01    EVENTS OF DEFAULT. Each of the following events constitutes an
Event of Default under this Agreement:

         (a)      Any Borrower or any Guarantor fails to pay any principal
component of any Obligation payable by it when due and payable or fails to pay
any interest thereon or fee payable by it within three (3) Business Days after
the date when due and payable or fails to pay any other Obligation within ten
(10) Business Days after the date when due and payable, whether at a date for
the payment of a fixed installment or as a contingent or other payment becomes
due and payable or as a result of acceleration or otherwise;

         (b)      Any "default" or "event of default" occurs under any Loan
Document which defines either such term, and the same is not remedied within the
applicable period of grace (if any) provided in such Loan Document;

         (c)      Any Restricted Person fails (other than as referred to in
subsections (a) or (b) above) to (i) duly comply with Section 8.11 of this
Agreement or (ii) duly observe, perform or comply with any other covenant,
agreement, condition or provision of any Loan Document, and such failure remains
unremedied for a period of thirty (30) days after notice of such failure is
given by Administrative Agent to the 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 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, the US Borrower shall (subject to the other provisions of this
Section 10.01) have a period of 30 days after written notice thereof has been
given to the US Borrower by Administrative Agent within which to remedy or cure
such falsity or lack of correctness; or this Agreement, any Note, or Guaranty
executed by any Guarantor is asserted to be or at any time ceases to be valid,
binding and enforceable in any material respect as warranted in Section 7.05 for
any reason other than its release or subordination by Administrative Agent;

         (e)      Any Restricted Person (i) 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 under this clause (ii) 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 utilization of the proceeds of such Indebtedness in connection

<PAGE>

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 the Threshold Amount, 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 the Threshold Amount;

         (g)      Any Change of Control occurs;

         (h)      Any Borrower, any Guarantor or any other Restricted Person
having assets with a book value equal to or greater than the Threshold Amount:

                  (i)      institutes or consents to the institution of any
         proceeding under any Debtor Relief Law, or makes an assignment for the

                                   ARTICLE XI.
                              ADMINISTRATIVE AGENT

         11.01    APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT.

         (a)      Each Lender hereby irrevocably appoints, designates and
authorizes the Administrative Agent to take such action on its behalf under the
provisions of this Agreement and each other Loan Document and to exercise such
powers and perform such duties as are expressly delegated to it by the terms of
this Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative
Agent shall not have any duties or responsibilities, except those expressly set
forth herein, nor shall the Administrative Agent have or be deemed to have any
fiduciary relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Loan Documents with
reference to the Administrative 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)      The applicable L/C Issuer shall act on behalf of the Lenders
with respect to any Letters of Credit issued by it and the documents associated
therewith, and such L/C Issuer shall have all of the benefits and immunities (i)
provided to the Administrative Agent in this Article XI with respect to any acts
taken or omissions suffered by such L/C Issuer in connection with Letters of
Credit issued by it or proposed to be issued by it and the applications and
agreements for letters of credit pertaining to such Letters of Credit as fully
as if the term "Administrative Agent" as used in this Article XI and in the
definition of "Agent-Related Person" included such L/C Issuer with respect to
such acts or omissions, and (ii) as additionally provided herein with respect to
any L/C Issuer.

         11.02    DELEGATION OF DUTIES. The Administrative Agent may execute any
of its duties under this Agreement or any other Loan Document by or through
agents, employees or attorneys-in-fact, including without limitation the
execution by Administrative Agent of duties relating to the Canadian SubFacility
and shall be entitled to advice of counsel and other consultants or experts
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects in the absence of gross negligence or willful
misconduct, including but not limited to those used in connection with the
Canadian SubFacility.

                                                          DEVON CREDIT AGREEMENT

                                      111
<PAGE>

         11.03    LIABILITY OF ADMINISTRATIVE AGENT. No Agent-Related Person
shall (a) be liable for any action taken or omitted to be taken by any of them
under or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or willful
misconduct in connection with its duties expressly set forth herein), or (b) be
responsible in any manner to any Lender or participant for any recital,
statement, representation or warranty made by any Loan Party or any officer
thereof, contained herein or in any other Loan Document, or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Administrative Agent under or in connection with, this Agreement or any
other Loan Document, or the validity, effectiveness, genuineness, enforceability
or sufficiency of this Agreement or any other Loan Document, or for any failure
of any Loan Party or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Lender or participant to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of any Loan Party or any Affiliate thereof.

         11.04    RELIANCE BY ADMINISTRATIVE AGENT.

         (a)      The Administrative Agent shall be entitled to rely, and shall
be fully protected in relying, upon any writing, communication, signature,
resolution, representation, notice, consent, certificate, affidavit, letter,
telegram, facsimile, telex or telephone message, electronic mail message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel (including counsel to any Loan
Party), independent accountants and other experts selected by the Administrative
Agent. The Administrative Agent shall be fully justified in failing or refusing
to take any action under any Loan Document unless it shall first receive such
advice or concurrence of the Required Lenders as it deems appropriate and, if it
so requests, 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 or continuing to take any such action. The Administrative 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 Required Lenders (or such greater number of Lenders as may be
expressly required hereby in any instance) and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders.

         (b)      For purposes of determining compliance with the conditions
specified in Section 6.01, 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 required thereunder to be consented to or approved by
or acceptable or satisfactory to a Lender unless the Administrative Agent shall
have received notice from such Lender prior to the proposed Closing Date
specifying its objection thereto.

         11.05    NOTICE OF DEFAULT. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default, except with
respect to defaults in the payment of principal, interest and fees required to
be paid to the Administrative Agent for the account of the Lenders, unless the
Administrative Agent shall have received written notice from

                                                          DEVON CREDIT AGREEMENT

                                      112
<PAGE>

a Lender or a Borrower referring to this Agreement, describing such Default and
stating that such notice is a "notice of default." The Administrative Agent will
notify the Lenders of its receipt of any such notice. The Administrative Agent
shall take such action with respect to such Default as may be directed by the
Required Lenders in accordance with Section 10.02; provided, however, that
unless and until the Administrative Agent has received any such direction, the
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default as it shall deem
advisable or in the best interest of the Lenders.

         11.06    CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Loan Party or any Affiliate thereof, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
to any Lender as to any matter, including whether Agent-Related Persons have
disclosed material information in their possession. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the applicable Borrowers hereunder. Each Lender also
represents that it will, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Borrowers. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent herein, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of any of the Loan Parties or any of
their respective Affiliates which may come into the possession of any
Agent-Related Person.

         11.07    INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, the Lenders shall indemnify
upon demand each Agent-Related Person (to the extent not reimbursed by or on
behalf of any Loan Party and without limiting the obligation of any Loan Party
to do so), pro rata, and hold harmless each Agent-Related Person from and
against any and all Indemnified Liabilities incurred by it, provided, however,
that no Lender shall be liable for the payment to any Agent-Related Person of
any portion of such Indemnified Liabilities to the extent determined in a final,
nonappealable judgment by a court of competent jurisdiction to have resulted
from such Agent-Related Person's own gross negligence or willful misconduct;
provided, however, that no action taken in accordance with the directions of the
Required Lenders or all the Lenders, if applicable, shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section.

                                                          DEVON CREDIT AGREEMENT

                                      113
<PAGE>

Without limitation of the foregoing, each Lender shall reimburse the
Administrative Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including Attorney Costs) incurred by the Administrative
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Administrative
Agent is not reimbursed for such expenses by or on behalf of the Borrowers. The
undertaking in this Section shall survive termination of the Aggregate
Commitments, the payment of all other Obligations and the resignation of the
Administrative Agent.

         11.08    BANK OF AMERICA IN ITS INDIVIDUAL CAPACITY. Bank of America
(acting through its Canadian branch or otherwise) 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 Loan Parties
and their respective Affiliates as though Bank of America (acting through its
Canadian branch or otherwise) were not the Administrative Agent or L/C Issuer
hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, Bank of America or its Affiliates
may receive information regarding any Loan Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Loan Party or such Affiliate) and acknowledge that the Administrative Agent
shall be under no obligation to provide such information to them. With respect
to its Loans, Bank of America (acting through its Canadian branch or otherwise)
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 Administrative
Agent or L/C Issuer, and the terms "Lender," "Lenders," "Canadian Lender," and
"Canadian Lenders" include Bank of America in its individual capacity.

         11.09    SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders and the
Borrowers; provided that any such resignation by Bank of America shall also
constitute its resignation as US Swing Line Lender and Canadian Swing Line
Lender, and, so long as one or more financial institutions reasonably acceptable
to the Borrowers have accepted their appointment as a successor US L/C Issuer
and Canadian L/C Issuer, as US L/C Issuer and Canadian L/C Issuer with respect
to Letters of Credit requested by the applicable Borrower to be issued on or
after the effective date of such resignation. If the Administrative Agent
resigns under this Agreement, (a) the Required Lenders shall appoint from among
the Lenders (that are also Canadian Lenders) a successor administrative agent
(the "successor Administrative Agent") for the Lenders, which successor
Administrative Agent shall be consented to by the US Borrower at all times other
than during the existence of an Event of Default (which consent of the US
Borrower shall not be unreasonably withheld or delayed). If no successor
Administrative Agent is appointed, prior to the effective date of the
resignation of the Administrative Agent, the Administrative Agent may appoint,
after consulting with the Lenders and the US Borrower, a successor
Administrative Agent from among the Lenders (that are also Canadian Lenders).
Upon the acceptance of its appointment as successor Administrative Agent
hereunder, the Persons acting as such successor Administrative Agent shall
succeed to all the respective rights, powers and duties of the retiring
Administrative Agent, US L/C Issuer, Canadian L/C Issuer, US Swing Line Lender
and Canadian Swing Line

                                                          DEVON CREDIT AGREEMENT

                                      114
<PAGE>

Lender and the respective terms "Administrative Agent," "US L/C Issuer,"
"Canadian L/C Issuer," "US Swing Line Lender," and "Canadian Swing Line Lender,"
shall mean such successor Administrative Agent, US L/C Issuer, Canadian L/C
Issuer, US Swing Line Lender and Canadian Swing Line Lender, as applicable, the
retiring Administrative Agent's appointment, powers and duties as Administrative
Agent shall be terminated, and the retiring US L/C Issuer's, Canadian L/C
Issuer's, US Swing Line Lender's and Canadian Swing Line Lender's rights, powers
and duties as such shall be terminated, except with respect to Letters of Credit
issued by it as US L/C Issuer or Canadian L/C Issuer prior to the effective date
of its resignation. All of the provisions of this Agreement that apply to such
Letters of Credit shall continue in full force and effect, without any other or
further act or deed on the part of such retiring L/C Issuer or Swing Line Lender
or any other Lender. The successor L/C Issuers may issue letters of credit in
substitution for the Letters of Credit issued by Bank of America in its capacity
as L/C Issuer, if any, outstanding at the time of such succession. After any
retiring Administrative Agent's resignation hereunder as Administrative Agent,
the provisions of this Article XI and Sections 12.04 and 12.05 shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor Administrative Agent
has accepted appointment as Administrative Agent by the date which is 30 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
Administrative Agent as provided for above.

         11.10    ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIM. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to any Loan Party, the Administrative Agent (irrespective of
whether the principal of any Loan or L/C Obligation shall then be due and
payable as herein expressed or by declaration or otherwise and irrespective of
whether the Administrative Agent shall have made any demand on the applicable
Borrower) shall be entitled and empowered, by intervention in such proceeding or
otherwise

         (a)      to file and prove a claim for the whole amount of the
principal and interest owing and unpaid in respect of the Loans, L/C Obligations
and all other Obligations that are owing and unpaid and to file such other
documents as may be necessary or advisable in order to have the claims of the
Lenders and the Administrative Agent (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Lenders and the
Administrative Agent and their respective agents and counsel and all other
amounts due the Lenders and the Administrative Agent under Sections 2.04(i) and
(j), 4.02 and 12.04) allowed in such judicial proceeding; and

         (b)      to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to the Administrative Agent and, in the event

Required Lenders will confirm in writing the Administrative Agent's authority to

relied, and will not rely, on any of the Persons so identified in deciding to
enter into this Agreement or in taking or not taking action hereunder.

Administrative Agent and the Lenders shall be entitled to rely and act upon any
notices (including telephonic US Committed Loan Notices, Canadian Committed

thereof. The US Borrower shall indemnify each Agent-Related Person and each
Lender, and each Canadian Borrower shall, jointly and severally, indemnify each
Agent-Related Person and each Canadian Lender, from all losses, costs, expenses
and liabilities resulting from the reliance by such Person on each notice

communications with the Administrative Agent may be recorded by the
Administrative Agent, and each of the parties hereto hereby consents to such
recording.

         12.03    NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or
the Administrative Agent to exercise, and no delay by any such Person in
exercising, any right, remedy, power or privilege hereunder shall operate as a

power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights,
remedies, powers and privileges herein provided are cumulative and not exclusive
of any rights, remedies, powers and privileges provided by law.

         12.04    ATTORNEY COSTS AND EXPENSES. The US Borrower agrees (a) to pay

the transactions contemplated hereby and thereby, including all Attorney Costs
(but not other costs of legal counsel), and (b) to pay or reimburse the

Liabilities"), in all cases, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN
PART, OUT OF THE NEGLIGENCE OF THE INDEMNITEE; provided that such indemnity
shall not, as to any Indemnitee, be available to the extent that such
liabilities, obligations, losses, damages, penalties, claims, demands, actions,
judgments, suits, costs, expenses or disbursements are determined by a court of
competent jurisdiction by final judgment to have resulted from the gross

         (b)      Subject to the following requirements of this Section 12.08,
and in the case of Bank of America, Section 11.09, any Lender may at any time

and the Loans (including for purposes of this subsection (b), participations in
L/C Obligations and in Swing Line Loans) at the time owing to it); provided that
(i) except in the case of an assignment of the entire remaining amount of the
assigning Lender's Commitment and the Obligations at the time owing to it or in

outstanding thereunder) subject to each such assignment, determined as of the
date the Assignment and Assumption with respect to such assignment is delivered
to the Administrative Agent or, if "Trade Date" is specified in the Assignment
and Assumption, as of the Trade Date, shall not be less than US $10,000,000
unless each of the Administrative Agent and, so long as no Event of Default has

Assignee); and (iv) the parties to each assignment shall execute and deliver to
the Administrative Agent an Assignment and Assumption, together with a
processing and recordation fee of US $3,500. Subject to acceptance and recording
thereof by the Administrative Agent pursuant to subsection (c) 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
rights and obligations under this Agreement of the assigning Lender, 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 5.01, 5.04, 5.05, 12.04, 12.05 and 12.06 with respect to
facts and circumstances occurring prior to the effective date of such
assignment). Upon request, each applicable Borrower (at its expense) shall
execute and deliver a Note to the assignee Lender. 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.

         (c)      The Administrative Agent, acting solely for this purpose as an
agent of the Borrowers, shall maintain at the Administrative Agent's Office a

recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amounts of the Loans and L/C Obligations owing to, each Lender
pursuant to the terms hereof from time to time (the "Register"). The entries in
the Register shall be conclusive, and the Borrowers, the Administrative Agent
and the Lenders may treat each Person whose name is recorded in the Register
pursuant to the terms hereof as a Lender hereunder for all purposes of this
Agreement, notwithstanding notice to the contrary. The Register shall be
available for inspection by the Borrowers and the Lenders at any reasonable time
and from time to time upon reasonable prior notice. In addition, at any time
that a request for a consent for a material or other substantive change to the
Loan Documents is pending, any Lender wishing to consult with other Lenders in
connection therewith may request and receive from the Administrative Agent a
copy of the Register.

         (d)      Any Lender may at any time, without the consent of, or notice
to, the Borrowers or the Administrative Agent, sell participations to any Person
(other than a natural person or any Borrower or any Affiliates or Subsidiaries
of any Borrower) (each, a "Participant") in all or a portion of such Lender's
rights and/or obligations under this Agreement (including all or a portion of
its Commitment and/or the Loans and Bankers' Acceptances (including such
Lender's participations in L/C Obligations and/or Swing Line Loans owing to it);
provided 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 and (iii) the Borrowers, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. 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 agreement or instrument may provide that such Lender will not, without
the consent of the Participant, agree to any amendment, waiver or other
modification described in the first proviso to Section 12.01 that directly
affects such Participant. Subject to subsection (e) of this Section, Borrowers
agree that each Participant shall be entitled to the benefits of Sections 5.01,
5.04 and 5.05 to the same extent as if it were a Lender and had acquired its
interest by assignment pursuant to subsection (b) of this Section. To the extent
permitted by law, each Participant also shall be entitled to the benefits of
Section 12.10 as though it were a Lender, provided such Participant agrees to be
subject to Section 4.06 as though it were a Lender.

         (e)      A Participant shall not be entitled to receive any greater
payment under Section 5.01 or 5.04 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
Borrowers' prior written consent. A Participant that would be a Non-US Lender if
it were a Lender shall not be entitled to the benefits of Section 5.01 unless
the Borrowers are notified of the participation sold to such Participant and
such Participant agrees, for the benefit of the Borrowers, to comply with
Section 12.16 as though it were a Lender.

         (f)      Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement (including
under its Note, if any) to secure obligations of such Lender, including any
pledge or assignment to secure obligations to a Federal Reserve Bank; provided
that no such pledge or assignment shall release such Lender from any of its
obligations hereunder or substitute any such pledgee or assignee for such Lender
as a party hereto.

         (g)      As used herein, the following terms have the following
meanings:

                  "Eligible Assignee" means (a) a Lender; (b) an Affiliate of a
         Lender; (c) an Approved Fund; and (d) any other Person (other than a
         natural person) approved by (i) the Administrative Agent, the L/C
         Issuer, the US Swing Line Lender, and the Canadian Swing Line Lender,
         and (ii) unless an Event of Default has occurred and is continuing, the
         US Borrower (with respect to a Lender) or the Canadian Borrowers (with
         respect to a Canadian Lender) (each such approval not to be
         unreasonably withheld or delayed); provided that notwithstanding the
         foregoing, "Eligible Assignee" shall not include (A) any Borrower or
         any Affiliates or Subsidiaries of any Borrower or (B) any Canadian
         Lender that is not a Canadian Resident Lender.

                  "Fund" means any Person (other than a natural person) that is
         engaged in making and holding commercial loans and similar extensions
         of credit in the ordinary course of its business.

                  "Approved Fund" means any Fund that is administered or managed
         by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an
         Affiliate of an entity that administers or manages a Lender.

         (h)      Notwithstanding anything to the contrary contained herein, if
at any time Bank of America assigns all of its Commitment and Loans pursuant to
subsection (b) above, Bank of

                                                          DEVON CREDIT AGREEMENT

America may, (i) upon 30 days' notice to the Borrowers and the Lenders, and, so
long as one or more financial institutions reasonably acceptable to the
Borrowers have accepted their appointment as a successor L/C Issuer, resign as
L/C Issuer and/or (ii) upon 30 days' notice to the Borrowers, resign as US Swing
Line Lender and Canadian Swing Line Lender. In the event of any such resignation
as L/C Issuer, US Swing Line Lender, or Canadian Swing Line Lender, the US
Borrower shall be entitled to appoint from among the Lenders a successor US L/C
Issuer or US Swing Line Lender hereunder, and the Canadian Borrowers shall be
entitled to appoint from among the Canadian Lenders a successor Canadian L/C
Issuer or Canadian Swing Line Lender hereunder; provided, however, that no
failure by any Borrower to appoint any such successor shall affect the
resignation of Bank of America as (except as provided above) L/C Issuer, US
Swing Line Lender, or Canadian Swing Line Lender, as the case may be. If Bank of
America resigns as L/C Issuer, it shall retain all the rights and obligations of
the L/C Issuer hereunder with respect to all Letters of Credit outstanding as of
the effective date of its resignation as L/C Issuer and all L/C Obligations with
respect thereto (including the right to require the Lenders to make Base Rate
Committed Loans or fund risk participations in US Unreimbursed Amounts pursuant
to Section 2.04(c) and to require the Canadian Lenders to make Canadian Prime
Rate Committed Loans or fund risk participations in Canadian Unreimbursed
Amounts pursuant to Section 3.04(c). If Bank of America resigns as US Swing Line
Lender or Canadian Swing Line Lender, it shall retain all the rights of the US
Swing Line Lender or Canadian Swing Line Lender, as applicable, provided for
hereunder with respect to Swing Line Loans made by it and outstanding as of the
effective date of such resignation, including the right to require the Lenders
to make Base Rate Committed Loans or fund risk participations in outstanding
Swing Line Loans pursuant to Section 2.05(c).

         12.09    CONFIDENTIALITY. Each of the Administrative Agent and the
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its Affiliates and to
its and its Affiliates' respective partners, directors, officers, employees,
agents, advisors and representatives (it being understood that the Persons to
whom such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential) and that the
Lender providing any such Information shall be responsible for the breach
thereof by any such Person, (b) to the extent requested by any regulatory
authority purporting to have jurisdiction over it (including any self-regulatory
authority, such as the National Association of Insurance Commissioners), (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process; provided that Administrative Agent or such Lender, as
applicable, shall notify US Borrower if disclosure of such Information is so
required, to the extent it is not prohibited from doing so by any Law or such
subpoena or legal process, (d) to any other party hereto, (e) in connection with
the exercise of any remedies hereunder or under any other Loan Document or any
action or proceeding relating to this Agreement or any other Loan Document or
the enforcement of rights hereunder or thereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section, to (i)
any assignee of or Participant in, or any prospective assignee of or Participant
in, any of its rights or obligations under this Agreement or (ii) any actual or
prospective counterparty (or its advisors) to any swap or derivative transaction
relating to any Borrower and its obligations, (g) with the consent of any
Borrower, or (h) to the extent such Information (x) becomes publicly available
other than as a result of a breach of this Section or (y) becomes available to
the Administrative Agent or any Lender on a nonconfidential basis from

                                                          DEVON CREDIT AGREEMENT

                                      125
<PAGE>

a source other than any Borrower unless Administrative Agent or such Lender, as
applicable, shall know that such source was required to keep such information
confidential. For purposes of this Section, "Information" means all information
received from any Borrower or any of its Subsidiaries relating to such Borrower
or any Subsidiary or any of their respective businesses, other than any such
information that is available to the Administrative Agent or any Lender on a
nonconfidential basis prior to disclosure by such Borrower or any Subsidiary,
provided that, in the case of information received from any Borrower or any
Subsidiary after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

         12.10    BANK ACCOUNTS; OFFSET. (a) The US Borrower hereby agrees that
each 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
Documents, or otherwise) (a) any and all moneys, securities or other property
(and the proceeds therefrom) of such Borrower now or hereafter held or received
by or in transit to any Lender for the account of the US Borrower, (b) any and
all deposits (general or special, time or demand, provisional or final) of the
US Borrower with any Lender, (c) any other credits and balances of the US
Borrower at any time existing against any Lender, including claims under
certificates of deposit, and (d) any indebtedness owed or payable by any Lender
to the US Borrower at any time against Obligations due to it that have not been
paid when due. At any time and from time to time after the occurrence of any
Event of Default and during the continuance thereof, each Lender is hereby
authorized to offset against the Obligations then due and payable to it (in
either case without notice to the US Borrower), any and all items hereinabove
referred to. To the extent that the 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 the US Borrower for the account of, third party royalty or joint
interest owners. Each Lender agrees promptly to notify each applicable Borrower
and the Administrative Agent after any such set-off and application made by such
Lender; provided, however, that the failure to give such notice shall not affect
the validity of such set-off and application.

         (b)      Each Canadian Borrower hereby agrees that each Canadian Lender
shall have the right to offset (which shall be in addition to all other
interests, liens, and rights of such Canadian Lender at common Law, under the
Loan Documents, or otherwise) (a) any and all moneys, securities or other
property (and the proceeds therefrom) of such Canadian Borrower now or hereafter
held or received by or in transit to any Canadian Lender for the account of such
Canadian Borrower, (b) any and all deposits (general or special, time or demand,
provisional or final) of such Canadian Borrower with any Canadian Lender, (c)
any other credits and balances of such Canadian Borrower at any time existing
against any Canadian Lender, including claims under certificates of deposit, and
(d) any indebtedness owed or payable by any Canadian Lender to such Canadian
Borrower at any time against Canadian Obligations due to it that have not been
paid when due. At any time and from time to time after the occurrence of any
Event of Default and during the continuance thereof, each Canadian Lender is
hereby authorized to offset against the Canadian Obligations then due and
payable to it by such Canadian Borrower (in either case

                                                          DEVON CREDIT AGREEMENT

                                      126
<PAGE>

without notice to such Canadian Borrower), any and all items hereinabove
referred to. To the extent that either Canadian 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 such Canadian Borrower for the account of, third party royalty or
joint interest owners. Each Canadian Lender agrees promptly to notify each
Canadian Borrower and the Administrative Agent after any such set-off and
application made by such Canadian Lender; provided, however, that the failure to
give such notice shall not affect the validity of such set-off and application.

         12.11    INTEREST RATE LIMITATION. Notwithstanding anything to the
contrary contained in any Loan Document, the interest paid or agreed to be paid
under the Loan Documents shall not exceed the maximum rate of non-usurious
interest permitted by applicable Law (the "Maximum Rate"). If the Administrative
Agent or any Lender shall receive interest in an amount that exceeds the Maximum
Rate, the excess interest shall be applied to the principal of the Loans or, if
it exceeds such unpaid principal, refunded to the applicable Borrower. In
determining whether the interest contracted for, charged, or received by the
Administrative Agent or a Lender exceeds the Maximum Rate, such Person may, to
the extent permitted by applicable Law, (a) characterize any payment that is not
principal as an expense, fee, or premium rather than interest, (b) exclude
voluntary prepayments and the effects thereof, and (c) amortize, prorate,
allocate, and spread in equal or unequal parts the total amount of interest
throughout the contemplated term of the Obligations hereunder. In no event shall
the aggregate "interest" (as defined in section 347 of the Criminal Code
(Canada)) payable with respect to any Canadian Obligations 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, Administrative Agent and Lenders and the amount of such
excess payment or collection shall be refunded to Canadian Borrowers. For
purposes of the Canadian Obligations, 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 Administrative Agent shall be prima facie evidence, for
the purposes of such determination.

         12.12    COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         12.13    INTEGRATION. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and thereof and supersedes all prior agreements, written
or oral, on such subject matter. In the event of any conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control; provided that the inclusion of
supplemental rights or remedies in favor of the Administrative Agent or the
Lenders in any other Loan Document shall not be deemed a conflict with this
Agreement. Each Loan Document was drafted with the

                                                          DEVON CREDIT AGREEMENT

                                      127
<PAGE>

joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof.

         12.14    SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made hereunder and in any other Loan Document or
other document delivered pursuant hereto or thereto or in connection herewith or
therewith shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default at the time of any US Credit Extension, and shall continue in full
force and effect as long as any Loan or any other Obligation hereunder shall
remain unpaid or unsatisfied or any US Letter of Credit shall remain
outstanding.

         12.15    SEVERABILITY. If any provision of this Agreement or the other
Loan Documents is held to be illegal, invalid or unenforceable, (a) the
legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby
and (b) the parties shall endeavor in good faith negotiations to replace the
illegal, invalid or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         12.16    TAX FORMS. (a) (i) Each Lender that is not a "United States
person" within the meaning of Section 7701(a)(30) of the Code (a "Non-US
Lender") shall deliver to the US Borrower and Administrative Agent, prior to
receipt of any payment subject to withholding under the Code (or upon accepting
an assignment of an interest herein), two duly signed completed copies of either
IRS Form W-8BEN or any successor thereto (relating to such Non-US Lender and
entitling it to an exemption from, or reduction of, withholding tax on all
payments to be made to such Non-US Lender by any Borrower pursuant to this
Agreement) or IRS Form W-8ECI or any successor thereto (relating to all payments
to be made to such Non-US Lender by any Borrower pursuant to this Agreement) or
such other evidence satisfactory to the applicable Borrower and the
Administrative Agent that such Non-US Lender is entitled to an exemption from,
or reduction of, U.S. withholding tax, including any exemption pursuant to
Section 881(c) of the Code. Thereafter and from time to time, each such Non-US
Lender shall (A) promptly submit to the US Borrower and Administrative Agent
such additional duly completed and signed copies of one of such forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
applicable Borrower and the Administrative Agent of any available exemption from
or reduction of, United States withholding taxes in respect of all payments to
be made to such Non-US Lender by the applicable Borrower pursuant to this
Agreement, (B) promptly notify the US Borrower and Administrative Agent of any
change in circumstances which would modify or render invalid any claimed
exemption or reduction, and (C) take such steps as shall not be materially
disadvantageous to it, in the reasonable judgment of such Lender, and as may be
reasonably necessary (including the re-designation of its Lending Office) to
avoid any

                                                          DEVON CREDIT AGREEMENT

                                      128
<PAGE>

requirement of applicable Laws that the applicable Borrower make any deduction
or withholding for taxes from amounts payable to such Non-US Lender.

                  (ii)     Each Non-US Lender, to the extent it does not act or
         ceases to act for its own account with respect to any portion of any
         sums paid or payable to such Lender under any of the Loan Documents
         (for example, in the case of a typical participation by such Lender),
         shall deliver to the Administrative Agent and the US Borrower on the
         date when such Non-US Lender ceases to act for its own account with
         respect to any portion of any such sums paid or payable, and at such
         other times as may be necessary in the determination of the
         Administrative Agent (in the reasonable exercise of its discretion),
         (A) two duly signed completed copies of the forms or statements
         required to be provided by such Lender as set forth above, to establish
         the portion of any such sums paid or payable with respect to which such
         Lender acts for its own account that is not subject to U.S. withholding
         tax, and (B) two duly signed completed copies of IRS Form W-8IMY (or
         any successor thereto), together with any information such Lender
         chooses to transmit with such form, and any other certificate or
         statement of exemption required under the Code, to establish that such
         Lender is not acting for its own account with respect to a portion of
         any such sums payable to such Lender.

                  (iii)    No Borrower shall be required to pay any additional
         amount to any Non-US Lender under Section 5.01 (A) with respect to any
         Taxes required to be deducted or withheld on the basis of the
         information, certificates or statements of exemption such Lender
         transmits with an IRS Form W-8IMY pursuant to this Section 12.16(a) or
         (B) if such Lender shall have failed to satisfy the foregoing
         provisions of this Section 12.16(a); provided that if such Lender shall
         have satisfied the requirement of this Section 12.16(a) on the date
         such Lender became a Lender or ceased to act for its own account with
         respect to any payment under any of the Loan Documents, nothing in this
         Section 12.16(a) shall relieve the applicable Borrower of its
         obligation to pay any amounts pursuant to Section 5.01 in the event
         that, as a result of any change in any applicable law, treaty or
         governmental rule, regulation or order, or any change in the
         interpretation, administration or application thereof, such Lender is
         no longer properly entitled to deliver forms, certificates or other
         evidence at a subsequent date establishing the fact that such Lender or
         other Person for the account of which such Lender receives any sums
         payable under any of the Loan Documents is not subject to withholding
         or is subject to withholding at a reduced rate.

                  (iv)     The Administrative Agent may, without reduction,
         withhold any Taxes required to be deducted and withheld from any
         payment under any of the Loan Documents with respect to which no
         Borrower is required to pay additional amounts under this Section
         12.16(a).

         (b)      Upon the request of the Administrative Agent, each Lender that
is a "United States person" within the meaning of Section 7701(a)(30) of the
Code shall deliver to the Administrative Agent two duly signed completed copies
of IRS Form W-9. If such Lender fails to deliver such forms, then the
Administrative Agent may withhold from any interest payment to

                                                          DEVON CREDIT AGREEMENT

                                      129
<PAGE>

such Lender an amount equivalent to the applicable back-up withholding tax
imposed by the Code, without reduction.

         (c)      If any Governmental Authority asserts that the Administrative
Agent did not properly withhold or backup withhold, as the case may be, any tax
or other amount from payments made to or for the account of any Lender, such
Lender shall indemnify the Administrative Agent therefor, including all
penalties and interest, any taxes imposed by any jurisdiction on the amounts
payable to the Administrative Agent under this Section, and costs and expenses
(including Attorney Costs) of the Administrative Agent. The obligation of the
Lenders under this Section shall survive the termination of the Aggregate
Commitments, repayment of all other Obligations hereunder and the resignation of
the Administrative Agent.

         12.17    REPLACEMENT OF LENDERS. In the event that any Lender shall (i)
claim payment of any amount pursuant to Section 5.01; (ii) claim any increased
cost pursuant to Section 5.04 or the benefit of Section 5.03; (iii) fail to
agree to extend the Maturity Date pursuant to Section 4.08, if the requisite
Lenders have agreed to do so; (iv) become and continue to be a Defaulting
Lender; or (v) fail to consent to an election, consent, amendment, waiver or
other modification to this Agreement or any other Loan Document that requires
the consent of a greater percentage of the Lenders than the Required Lenders,
the Required US Lenders or the Required Canadian Lenders, as the case may be,
and such election, consent, amendment, waiver or other modification is otherwise
consented to by the Required Lenders, the Required US Lenders or the Required
Canadian Lenders, as the case may be, (a) the US Borrower may, upon notice to
such Lender and the Administrative Agent, replace such Lender by causing such
Lender to assign its rights and obligations hereunder (with the assignment fee
to be paid by the US Borrower in such instance) pursuant to Section 12.08(b) to
one or more Eligible Assignees that are or have an affiliate that is a Canadian
Resident Lender, if applicable, procured by the US Borrower, each of which shall
assume a pro rata portion of the Commitment (including the Canadian Commitment,
if applicable) and the Credit Extensions of such replaced Lender; provided,
however, that if the US Borrower elects to exercise such right with respect to
any Lender pursuant to Section 5.01, 5.03 or 5.04 or, it shall be obligated to
replace all Lenders that have made similar requests for compensation or benefit
pursuant to Section 5.01, 5.03 or 5.04; or (b) the applicable Borrower may, upon
three Business Days' notice to such Lender through the Administrative Agent,
prepay in full all of the outstanding Loans and Bankers' Acceptances (as
applicable) of such Lender and all other Obligations owing to such Lender, or
its assignee, together with accrued interest thereon to the date of prepayment
and all other amounts owed by the Borrowers to such Lender accrued to the date
of prepayment, and concurrently therewith the US Borrower may terminate this
Agreement with respect to such Lender by giving notice of such termination to
Administrative Agent and such Lender. Upon satisfaction of the requirements set
forth above in clause (a) of the preceding sentence, payment to the Lender to be
replaced of the purchase price in immediately available funds, and the payment
by the US Borrower of all requested costs accruing to the date of purchase which
the Borrowers are obligated to pay under Sections 5.01, 5.03 and 5.04 and all
other amounts owed by the Borrowers to such Lender (other than the principal of
and interest on the Credit Extension of such Lender, and accrued facility and
utilization fees, purchased by the Eligible Assignee) such Eligible Assignee
shall constitute a "Lender", and if applicable, a "Canadian Lender", hereunder,
as the case may be, and the Lender being so replaced shall no longer constitute
a "Lender" or "Canadian Lender" hereunder, as the case may be, and its

                                                          DEVON CREDIT AGREEMENT

                                      130
<PAGE>

Commitment, and if applicable, its Canadian Commitment, shall be deemed
terminated. If, however, (x) the Eligible Assignee fails to purchase such rights
and interest on such specified date in accordance with the terms of such offer,
the Borrowers shall continue to be obligated to pay amounts to such Lender or
Canadian Lender pursuant to Section 5.01 or increased costs pursuant to Section
5.04, as the case may be, or (y) the Lender proposed to be replaced fails to
consummate such purchase offer, the Borrowers shall not be obligated to pay to
such Lender or Canadian Lender such increased costs or additional amounts
incurred or accrued from and after the date of such purchase offer.

         12.18    GOVERNING LAW.

         (a)      THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK; PROVIDED THAT THE
ADMINISTRATIVE AGENT AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER
FEDERAL LAW.

         (b)      ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT
OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK
SITTING IN NEW YORK CITY OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF
SUCH STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE
BORROWERS, THE ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. EACH
OF THE BORROWERS, THE ADMINISTRATIVE AGENT AND EACH LENDER IRREVOCABLY WAIVES
ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN
