THEREFORE, in consideration of the mutual promises herein contained and for other valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties

ARTICLE I Definitions

SECTION
1.1Defined Terms.As used in this Agreement, the following terms have the meanings specified below:

"ABR", when used in reference to any Loan or Borrowing, refers to whether such Loan, or the Loans comprising such Borrowing, are bearing
interest at a rate determined by reference to the Alternate Base Rate.

"Acquisition" means the acquisition by Borrower or one of its wholly-owned Subsidiaries of Target as a result of a merger effected
pursuant to the terms and conditions of the Acquisition Documents.

"Acquisition Documents" means the Merger Agreement.

"Adjusted LIBO Rate" means, with respect to any Eurodollar Borrowing for any Interest Period, an interest rate per annum (rounded upwards,
if necessary, to the next 1/16 of 1%) equal to (a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve Rate.

"Administrative Questionnaire" means an Administrative Questionnaire in a form supplied by the Global Administrative Agent.

"Affiliate" means, with respect to a specified Person, another Person that directly, or indirectly through one or more intermediaries,
Controls or is Controlled by or is under common Control with the Person specified.

"Agents" means each of the Global Administrative Agent, the Co-Global Syndication Agents and the Co-U.S.
Documentation Agents.

"Agreement" means this Second Amended and Restated Credit Agreement, as it may be amended, supplemented, restated or otherwise modified
and in effect from time to time.

"Allocated Canadian Borrowing Base" means from time to time the "Allocated Canadian Borrowing Base" as determined in accordance with Section 2.7(d)(ii).

"Allocated U.S. Borrowing Base" means from time to time the "Allocated U.S. Borrowing Base" as determined in accordance with Section 2.7(d)(i).

"Alternate Base Rate" means, for any day, a rate per annum equal to the greater of (a) the Prime Rate in effect on such day, and

Rate shall be effective from and including the effective date of such change in the Prime Rate or the Federal Funds Effective Rate, respectively. If for any reason the Global Administrative Agent
shall have determined (which determination shall be conclusive and binding, absent manifest error) that it is unable to ascertain the Federal Funds Effective Rate for any reason, including, without
limitation, the inability or failure of the Global Administrative Agent to obtain sufficient bids or publications in accordance with the terms hereof, the Alternate Base Rate shall be the Prime Rate
until the circumstances giving rise to such inability no longer exist.

"Applicable Lending Office" means, for each Lender and for each Type of Loan, such office of such Lender (or of an Affiliate of such
Lender) as such Lender may from time to time specify in writing to the Global Administrative Agent and Borrower as the office by which its Loans of such Type are to be made and/or issued and
maintained.

Commitment. If the Commitments have terminated or expired, the Applicable Percentages shall be determined based upon the Commitments most recently set forth in the Register, giving effect to any
assignments made in accordance withSection 10.4or any increases or decreases in Commitments made in accordance with this Agreement.

the case may be, the applicable rate per annum set forth below in basis points under the caption "Eurodollar Loans," "ABR Loans" or "Commitment Fees," as the case may be, based on the Global Borrowing

ARTICLE II The Credits

SECTION
2.1Commitments.Subject to the terms and conditions set forth herein, each Lender agrees to make Loans
in U.S. Dollars to Borrower from time to time during the Availability Period in an aggregate principal amount that will not result in (a) the Credit Exposure of any Lender exceeding the
Commitment of such Lender, or (b) the aggregate amount of the Credit Exposure of all Lenders exceeding the lesser of (i) the aggregate amount of the Allocated U.S. Borrowing Base then in
effect and (ii) the aggregate amount of the Commitments of the Lenders. Within the foregoing limits and subject to the terms and conditions set forth herein, Borrower may borrow, prepay and
reborrow Loans.

SECTION
2.2Loans and Borrowings.

(a)   Each
Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Applicable Percentages. The failure of
any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder;providedthat the Commitments of
the Lenders are several and no Lender shall be responsible for any other Lender's failure to make Loans as required.

(b)   Subject
toSections 2.13and2.14, each Borrowing shall be comprised
entirely of ABR Loans or Eurodollar Loans as Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate
of such Lender to make such Loan;providedthat any exercise of such option shall not affect the obligation of Borrower to repay such Loan in accordance
with the terms of this Agreement.

(c)   At
the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of U.S.$1,000,000
and not less than U.S.$2,000,000 (including any continuation or conversion of existing Loans made in connection therewith). At the time that each ABR Borrowing is made, such Borrowing shall be in an
aggregate amount that is an integral multiple of U.S.$1,000,000 and not less than U.S. $2,000,000 (including any continuation or conversion of existing Loans made in connection therewith); providedthat
an ABR Borrowing may be in an aggregate amount that is equal to the entire Unutilized Commitment, if less. Borrowings of more than one
Type may be outstanding at the same time;providedthat there shall not at any time be more than a total of ten (10) Eurodollar Borrowings
outstanding.

22

---



(d)   Notwithstanding any other provision of this Agreement, Borrower shall not be entitled to request, or to elect to convert or continue, any Eurodollar Borrowing if the
Interest Period requested with respect thereto would end after the Maturity Date.

SECTION
2.3Requests for Borrowings.To request a Borrowing, Borrower shall notify the Global Administrative
Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 1:00 p.m., New York City time, three Business Days before the date of the proposed Borrowing
or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be irrevocable
and shall be confirmed promptly by hand delivery or telecopy to the Global Administrative Agent of a written Borrowing Request executed by an Authorized Officer of Borrower, substantially in the form
ofExhibit E-1or otherwise in a form approved by the Global Administrative Agent. Each such telephonic and written Borrowing Request
shall specify the following information in compliance withSection 2.2:

(i)  the
aggregate amount of the requested Borrowing;

(ii)  the
date of such Borrowing, which shall be a Business Day;

(iii)  whether
such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv)  in
the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term
"Interest Period".

If
no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing,
then Borrower shall be deemed to have selected an Interest Period of one month's duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Global Administrative
Agent shall advise each Lender of the details thereof and of the amount of such Lender's Loan to be made as part of the requested Borrowing.

SECTION
2.4Letters of Credit.

(a)General.Subject to the terms and conditions set forth herein, Borrower may request the issuance of Letters
of Credit for its own account or the account of any Restricted Subsidiary, in a form reasonably acceptable to the Global Administrative Agent and the Issuing Bank, at any time and from time to time
during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other
agreement submitted by Borrower to, or entered into by Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b)Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions.To request the issuance of a Letter
of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), Borrower shall hand-deliver or telecopy (or transmit by electronic communication, if arrangements for
doing so have been approved by the Issuing Bank) to an Issuing Bank and the Global Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a
notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension
(which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply withparagraph (c)of this Section),
the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If
requested by the Issuing Bank, Borrower also shall submit a letter of credit application on the Issuing Bank's standard form in connection with any request for a Letter of Credit. A Letter of Credit
shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit Borrower shall be deemed to represent and warrant that), after giving
effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed the least of (A) the aggregate Commitments hereunder; (B) the

23

---



Allocated
U.S. Borrowing Base as then in effect at such time and (C) U.S.$100,000,000; and (ii) the aggregate Credit Exposure of the Lenders shall not exceed the lesser of (x) the
aggregate Commitments of the Lenders or (y) the Allocated U.S. Borrowing Base then in effect. The Global Administrative Agent shall use reasonable efforts to provide notice to the Lenders on a
quarterly basis with respect to the issuance, amendment, renewal or extension of Letters of Credit hereunder for such quarter.

(c)Expiration Date.Each Letter of Credit shall expire at or prior to the close of business on the earlier of
(i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and
(ii) five (5) Business Days prior to the Maturity Date.

(d)Participations.By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the
amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a
participation in such Letter of Credit equal to such Lender's Applicable Percentage of
the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the
Global Administrative Agent, for the account of the Issuing Bank, such Lender's Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by Borrower on the date due
as provided inparagraph (e)of this Section, or of any reimbursement payment required to be refunded to Borrower for any reason. Each Lender
acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that
each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e)Reimbursement.If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, Borrower
shall reimburse such LC Disbursement by paying to the Global Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC
Disbursement is made, if Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date; or, if such notice has not been received by Borrower
prior to such time on such date, then not later than 12:00 noon, New York City time, on the Business Day immediately following the day that Borrower receives such notice; providedthat, unless such LC
Disbursement is less than U.S.$1,000,000, Borrower may, subject to the conditions to Borrowing set forth herein, request
in accordance withSection 2.3that such payment be financed with a Borrowing in an equivalent amount and, to the extent so financed, Borrower's
obligation to make such payment shall be discharged and replaced by the resulting Borrowing. If Borrower fails to make such payment when due (or fails to request an ABR Loan Borrowing as provided
herein), the Global Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from Borrower in respect thereof and such Lender's Applicable Percentage
thereof. Promptly following receipt of such notice, each Lender shall pay to the Global Administrative Agent its Applicable Percentage of the payment then due from Borrower, in the same manner as
provided inSection 2.5with respect to Loans made by such Lender (andSection 2.5shall
apply,mutatis mutandis, to the payment obligations of the Lenders), and the Global Administrative Agent shall promptly pay to the Issuing Bank the
amounts so received by it from the Lenders. Promptly following receipt by the Global Administrative Agent of any payment from Borrower pursuant to this paragraph (or promptly following the Global
Administrative Agent's receipt from the Lenders of proceeds from a requested Borrowing), the Global Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that
Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to
this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than

24

---



the
funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve Borrower of its obligation to reimburse such LC Disbursement.

(f)Obligations Absolute.Borrower's obligation to reimburse LC Disbursements as provided in
paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement or any
other Loan Document, or any term or provision herein or therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect
or any statement therein proving to be untrue or inaccurate in any respect, (iii) payment by an Issuing Bank under a Letter of Credit against presentation of a draft or other document that does
not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of
this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, Borrower's obligations hereunder. Neither the Agents, the Lenders or any Issuing Bank nor any of their
Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder
(irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other
communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from
causes beyond the control of such Issuing Bank;providedthat the foregoing shall not be construed to excuse such Issuing Bank from liability to
Borrower to the extent of any direct or actual damages (as opposed to special, indirect, consequential or punitive damages, claims in respect of which are hereby waived by Borrower to the extent
permitted by applicable law) suffered by Borrower that are caused by such Issuing Bank's failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit
comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of
competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties
agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either
accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g)Disbursement Procedures.An Issuing Bank shall, promptly following its receipt thereof, examine all
documents purporting to represent a demand for payment under a Letter of Credit. Such Issuing Bank shall promptly notify the Global Administrative Agent and Borrower by telephone (confirmed by
telecopy) of such demand for payment and whether such Issuing Bank has made or will make an LC Disbursement thereunder;providedthat any failure to
give or delay in giving such notice shall not relieve Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h)Interim Interest.If an Issuing Bank shall make any LC Disbursement, then, unless Borrower shall reimburse
such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but
excluding the date that Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans;providedthat, if Borrower fails
to reimburse such LC Disbursement within two (2) Business Days after such reimbursement is due pursuant toparagraph (e)of this Section,
thenSection 2.12(c)shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest
accrued on and after the date of payment by any

25

---



Lender
pursuant toparagraph (e)of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such
payment.

(i)Cash Collateralization.If any Event of Default shall occur and be continuing, on the Business Day that
Borrower receives notice from the Global Administrative Agent or the Majority Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 50% of
the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, Borrower shall deposit in an account with the Global Administrative Agent, in the name of the Global
Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; providedthat the obligation to deposit
such cash collateral shall become effective immediately, and such deposit shall become immediately due and
payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to Borrower described in Section 8.1(g). Borrower also shall deposit cash collateral
pursuant to this paragraph as and to the extent required by Section 2.10, and any such cash collateral so deposited and held by the Global Administrative Agent hereunder shall constitute part of
the Global
Borrowing Base for purposes of determining compliance withSection 2.10. Each such deposit shall be held by the Global Administrative Agent as
collateral for the payment and performance of the obligations of Borrower under this Agreement. The Global Administrative Agent shall have exclusive dominion and control, including the exclusive right
of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Global Administrative
Agent and at Borrower's risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be
applied by the Global Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction
of the reimbursement obligations of Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing
greater than 50% of the total LC Exposure), be applied to satisfy other obligations of Borrower under this Agreement. If Borrower is required to provide an amount of cash collateral hereunder as a
result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to Borrower within three (3) Business Days after all Events of Default
have been cured or waived. If Borrower is required to provide an amount of cash collateral hereunder pursuant toSection 2.10, such amount (to
the extent not applied as aforesaid) shall be returned to Borrower as and to the extent that, after giving effect to such return, Borrower would remain in compliance with Section 2.10and no
Default shall have occurred and be continuing.

SECTION
2.5Funding of Borrowings.

(a)   Each
Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York
City time, to the account of the Global Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Global Administrative Agent will make such Loans available to
Borrower by promptly crediting the amounts so received, in like funds, to an account of Borrower maintained with the Global Administrative Agent in New York City; providedthat ABR Loans made to finance
the reimbursement of an LC Disbursement as provided in Section 2.4(e)shall be remitted by the Global Administrative Agent to the applicable Issuing Bank.

(b)   Unless
the Global Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to
the Global Administrative Agent such Lender's share of such Borrowing, the Global Administrative Agent may assume that such Lender has made such share available on such date in accordance with
paragraph (a) of this Section and may, in reliance upon such assumption, make available to Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the
applicable Borrowing available to the Global Administrative Agent, then the applicable Lender and Borrower severally agree to pay to the

26

---



Global
Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to Borrower to but excluding the
date of payment to the Global Administrative Agent, at (i) in the case of such Lender, the greater of (A) the Federal Funds Effective Rate or (B) a rate determined by the Global
Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of Borrower, the interest rate applicable to Loans made in such Borrowing. If such
Lender pays such amount to the Global Administrative Agent, then such amount shall constitute such Lender's Loan included in such Borrowing.

SECTION
2.6Interest Elections.

(a)   Borrower
may elect to convert a Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods
therefor, all as provided in this Section. Borrower may, subject to the requirements ofSection 2.2(c), elect different options with respect to
different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each
such portion shall be considered a separate Borrowing.

(b)   To
make an election pursuant to this Section, Borrower shall notify the Global Administrative Agent of such election by telephone by the time that a Borrowing Request
would be required underSection 2.3if Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective
date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Global Administrative Agent of a written
Interest Election Request executed by an Authorized Officer of Borrower, substantially in the form ofExhibit E-2or otherwise in a
form approved by the Global Administrative Agent.

(c)   Each
telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.2:



If
any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then Borrower shall be deemed to have selected an Interest Period of one month's
duration.

(d)   Promptly
following receipt of an Interest Election Request, the Global Administrative Agent shall advise each Lender of the details thereof and of such Lender's portion
of each resulting Borrowing.

(e)   If
Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then,
unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event
of Default has occurred and is continuing and the Global Administrative Agent, at the request of the Majority Lenders, so

27

---



notifies
Borrower, then, so long as such Event of Default is continuing, (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless the
Indebtedness has been accelerated pursuant toSection 8.3, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the
Interest Period applicable thereto.

SECTION
2.7Global Borrowing Base.This Section shall be applicable at all times.

(a)Initial Global Borrowing Base.Subject to Section 2.7(g), during the period from the date hereof to the date of the
first redetermination of the Global Borrowing Base pursuant to the
provisions of this Section, the initial amount of the Global Borrowing Base has been determined by the Global Administrative Agent and acknowledged by Borrower and its Restricted Subsidiaries
(including the Canadian Borrowers) and agreed to by the Combined Lenders to be U.S.$1,400,000,000. The Loan Value of the Borrowing Base Properties has been determined by the Global Administrative
Agent and acknowledged by Borrower and its Restricted Subsidiaries (including the Canadian Borrowers) and agreed to by the Combined Lenders.

(b)Annual Scheduled Determinations of the Global Borrowing Base.Promptly after January 1 of each
calendar year (commencing January 1, 2008), and in any event prior to March 15 of each calendar year, Borrower shall furnish to the Global Administrative Agent and the Combined Lenders a
report in form and substance reasonably satisfactory to the Global Administrative Agent, prepared by Borrower's internal petroleum engineers and audited by an Approved Engineer, which report shall
evaluate as of January 1 of such calendar year the Proven Reserves attributable to the Oil and Gas Properties which Borrower wishes to include in the Global Borrowing Base and a projection of
the rate of production and net operating income with respect thereto, as of such date, together with additional data concerning pricing, hedging, operating costs and quantities of production, and
other information and engineering and geological data as the Global Administrative Agent or any Combined Lender may reasonably request. Within 30 days after receipt of such report and
information, the Global Administrative Agent shall make an initial determination of the amount of credit to be made available to Borrower hereunder as of May 1st of such calendar year, and upon
such initial determination shall promptly notify the Combined Lenders in writing of the Global Administrative Agent's initial determination of the Global Borrowing Base. The Global Administrative
Agent shall make such determination in accordance with its customary practices and standards for oil and gas loans and in the exercise of its sole discretion. Within 15 days following their
receipt of the proposed amount for the redetermined Global Borrowing Base, the Borrowing Base Required Lenders shall approve or reject the Global Administrative Agent's initial determination of the
Global Borrowing Base by written notice to the Global Administrative Agent;provided,howeverthat
failure by any Combined Lender to reject in writing the Global Administrative Agent's determination of the Global Borrowing Base within such 15-day period shall be deemed an acceptance of
such determination by such Combined Lender. If the Borrowing Base Required Lenders fail to approve any such determination of the Global Borrowing Base made by the Global Administrative Agent
hereunder, then the Global Administrative Agent shall poll the Combined Lenders and the Global Borrowing Base shall be set at the highest amount on which the Borrowing Base Required Lenders can agree,
it being understood that a Combined Lender is deemed to have agreed to any and all amounts that are lower than the amount actually determined by such Combined Lender to be the appropriate value of the
Global Borrowing Base. Upon approval or deemed approval by the Borrowing Base Required Lenders of the Global Borrowing Base, the Global Administrative Agent upon notice thereof shall, by written
notice to Borrower, the Agents and the Combined Lenders, designate the new Global Borrowing Base available to Borrower and the Canadian Borrowers as of May 1st of such calendar year (each such
notice in thisSection 2.7(b)or2.7(c)below, herein a "Global Borrowing
Base Designation Notice"). Upon receipt of such Global Borrowing Base Designation Notice, Borrower shall designate the Allocated U.S. Borrowing Base and the Allocated Canadian
Borrowing Base to the Global Administrative Agent in accordance withSection 2.7(d).

28

(c)Semi-Annual Scheduled Determination of the Global Borrowing Base.In addition, promptly after
July 1 of each calendar year (commencing July 1, 2007, which will result in the first scheduled Global Borrowing Base redetermination), and in any event prior to September 15th of
each calendar year, Borrower will make available for review by the Global Administrative Agent a report in form and substance reasonably satisfactory to the Global Administrative Agent, prepared by
Borrower's internal petroleum engineers, which report shall evaluate as of July 1 of such calendar year the Proven Reserves attributable to the Oil and Gas Properties which Borrower wishes to
include in the Global Borrowing Base and a projection of the rate of production and net operating income with respect thereto, as of such date, together with additional data concerning pricing,
hedging, operating costs, and quantities of production, and other information and engineering and geological data as the Global
Administrative Agent or any Combined Lender may reasonably request. The Global Administrative Agent and the Borrowing Base Required Lenders shall approve and designate the new Global Borrowing Base as
of November 1st of such calendar year in accordance with the procedures and standards described inSection 2.7(b)and Borrower shall
provide a Global Borrowing Base Allocation Notice to the Global Administrative Agent in accordance withSection 2.7(d).

(d)Allocation of the Global Borrowing Base.The Global Borrowing Base shall be comprised of the Allocated U.S.
Borrowing Base and the Allocated Canadian Borrowing Base, and allocations between the Allocated U.S. Borrowing Base and Allocated Canadian Borrowing Base shall be made in accordance with this Section 2.7(d).



29

---





(e)Discretionary Determination of the Global Borrowing Base.Each of Borrower and the Global Administrative
Agent, at the request of the Borrowing Base Required Lenders, shall have the right to redetermine the Global Borrowing Base in their sole discretion at any time and from time to time but not more
often than one (1) time during any calendar year. If either Borrower or the Borrowing Base Required Lenders shall elect to make a discretionary redetermination of the Global Borrowing Base
pursuant to the provisions of thisSection 2.7(e), Borrower shall, within 30 days of receipt of a request therefor from the Global
Administrative Agent, deliver to the Global Administrative Agent such updated engineering, production, operating and other data as the Global Administrative Agent or any Combined Lender may reasonably
request. The Global Administrative Agent and the Borrowing Base Required Lenders shall approve and designate the new Global Borrowing Base in accordance with the procedures and standards described in Section 2.7(b)and Borrower shall provide a Global Borrowing Base Allocation Notice to the Global Administrative Agent in accordance with Section 2.7(d)(iii);providedthat in the event that Borrower fails to provide such Global
Borrowing Base Allocation
Notice, the Global Borrowing Base shall be allocated between the Allocated U.S. Borrowing Base and Allocated Canadian Borrowing Base in accordance with Section 2.7(d)(iii).

(f)General Provisions With Respect to the Global Borrowing Base.The determination of the Global Borrowing Base
shall be made by the Global Administrative Agent and the Borrowing Base Required Lenders, taking into consideration the estimated value of the Oil and Gas Properties owned by Borrower and its
Restricted Subsidiaries as reflected in the most recent Reserve Report delivered hereunder and any other relevant information obtained by or delivered to the Global Administrative Agent or any
Combined Lender, all in accordance with the other provisions of thisSection 2.7in accordance with their customary practices for oil and gas
loans as in effect from time to time. It is understood by the parties hereto that the Combined Lenders shall have no commitment or obligation whatsoever to increase the Global Borrowing Base to any
amount in excess of U.S.$1,400,000,000, and nothing herein contained shall be construed to be a commitment by the Combined Lenders to so increase the Global Borrowing Base. The Global Borrowing Base
may be redetermined pursuant toSection 2.7(b)(annual),Section 2.7(c)(semi-annual) andSection 2.7(e)(discretionary) and may be adjusted from time to time to give effect to issuances of Senior Notes
underSection 2.7(g), the occurrence of Casualty Events underSection 2.7(h), and asset
dispositions underSection 2.7(i). In

connection
with any redetermination or adjustment pursuant to any of the foregoing, if the Global Administrative Agent determines that either a Global Borrowing Base Deficiency or a U.S. Borrowing
Base Deficiency exists, the Global Administrative Agent shall give written notice thereof to Borrower and the date such notice is received shall be the "Deficiency Notification
Date".

(g)   In
the event that Borrower or any of its Restricted Subsidiaries issues any Senior Notes, then each of the Global Borrowing Base and the Allocated U.S. Borrowing Base
shall be reduced immediately by an amount equal to 30% of the stated principal amount of such issued Senior Notes;provided, however, that, notwithstanding
the foregoing, the Global Borrowing Base and the Allocated U.S. Borrowing Base shall not be reduced to the extent that
the proceeds from the issuance of such Senior Notes are used to refinance the principal amount of existing unsecured Indebtedness of the Borrower which constitutes Senior Notes.

(h)   In
the event that a Casualty Event has occurred related to any Borrowing Base Property, to the extent that the Net Proceeds received by Borrower or any of its Restricted
Subsidiaries with respect to such Casualty Event have not been applied or budgeted to be applied to repair, restore or replace the Property affected by such Casualty Event within 30 days after
the occurrence thereof, the Global Administrative Agent, at the request of the Borrowing Base Required Lenders, shall have the right to reduce the Global Borrowing Base in its sole discretion based on
its review of such Casualty Event;providedthat the Global Borrowing Base shall not be reduced by an amount greater than 100% of such Net Proceeds. The
Global Administrative Agent shall provide notice to Borrower and the Combined Lenders and the other Agents of the reduction in the Global Borrowing Base resulting from such Casualty Event, which
reduction shall be effective as of the date of such notice. Any such reduction in the Global Borrowing Base shall result in a corresponding reduction in the Allocated U.S. Borrowing Base (to the
extent that the Property which is the subject of such Casualty Event is located in the United States) or in the Allocated Canadian Borrowing Base (to the extent that the Property which is the subject
of such Casualty Event is located in Canada).

(i)    In
the event that Borrower sells, transfers or otherwise disposes in one or more transactions any Property pursuant to Section 7.5(g)if the aggregate fair market value of all such Property so sold,
transferred or otherwise disposed of during the period since the
most recent redetermination of the Global Borrowing Base shall exceed 10% of the amount of the then current Global Borrowing Base, then the Global Borrowing Base shall be reduced by an amount equal to
the Loan Value assigned to such Property in the most recently prepared Reserve Report (or if no such Loan Value was assigned, by an amount to be agreed upon by Borrower and the Global Administrative
Agent, acting reasonably). The Global Administrative Agent shall provide notice to Borrower and the Combined Lenders and the other Agents of the reduction in the Global Borrowing Base resulting from
such disposition, which reduction shall be effective as of the date of such notice. Any such reduction in the Global Borrowing Base shall result in a corresponding reduction in the Allocated U.S.
Borrowing Base (to the extent that the Property so sold, transferred or otherwise disposed of is located in the United States) or in the Allocated Canadian Borrowing Base (to the extent that the
Property so sold, transferred or otherwise disposed of is located in Canada).

SECTION

after giving effect to any concurrent prepayment of the Loans in accordance withSection 2.10, the aggregate Credit Exposure of the Lenders would
exceed the aggregate Commitments of the Lenders.

is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by Borrower (by notice to the Global Administrative Agent on or prior to the specified
effective date) if such condition is not satisfied. Subject to the rights of Borrower underSection 2.20, any termination or reduction of the
Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among each of the Lenders in accordance with each such Lender's Applicable Percentage.

any manner affect the obligation of Borrower to repay the Loans in accordance with the terms of this Agreement.

(e)   Any
Lender may request that Loans made by it be evidenced by one or more promissory notes. In such event, Borrower shall prepare, execute and deliver to such Lender
promissory notes payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns and in a form approved by the Global Administrative Agent). Thereafter,
the Loans evidenced by such promissory notes and interest thereon shall at all times (including after assignment pursuant toSection 10.4) be

the foregoing, but subject toSection 10.13, if any principal of or interest on any Loan or any
fee or other amount payable by Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before

Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d)   Subject
toSection 10.13, accrued interest on each Loan shall be payable in arrears on each Interest Payment Date

(e)   Subject
toSection 10.13, all interest hereunder shall be computed on the basis of a year of 360 days,
except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate, shall be computed on the basis of a year of 365 days (or
366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate,
Adjusted LIBO Rate or LIBO Rate shall be determined by the Global Administrative Agent, and such determination shall be conclusive absent manifest error.

SECTION
2.13Alternate Rate of Interest.If prior to the commencement of any Interest Period for a Eurodollar
Borrowing:

(a)   the
Global Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for
ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period;

(b)   the
Global Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate for such Interest Period will not adequately and fairly reflect the cost
to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; or

(c)   the
Global Administrative Agent determines in good faith (which determination shall be conclusive) that by reason of circumstances affecting the interbank dollar market
generally, deposits in U.S. Dollars in the London interbank dollar market are not being offered for the applicable Interest Period and in an amount equal to the amount of the Eurodollar Loan requested
by Borrower,

then
the Global Administrative Agent shall give notice thereof to Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Global Administrative Agent
notifies Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing for the affected Interest Period shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing
shall be made as a Eurodollar Loan having the shortest Interest Period which is not unavailable under clauses (a) through (c) of this Section, and if no Interest Period is available, as
an ABR Borrowing.

SECTION
2.14Illegality.

(a)   Notwithstanding
any other provision of this Agreement to the contrary, if (i) by reason of the adoption of any applicable Governmental Rule or any change in any
applicable Governmental Rule or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with any request or directive (whether or not having the force
of law) of any central bank or other Governmental Authority or (ii) circumstances affecting the London interbank dollar market or the position of a Lender therein shall at any time make it
unlawful or impracticable in the sole discretion of a Lender exercised in good faith for such Lender or its Applicable Lending Office to (A) honor its obligation to make Eurodollar Loans either
generally or for a particular Interest Period provided for hereunder, or (B) maintain Eurodollar Loans either generally or for a particular Interest Period provided for hereunder, then such
Lender shall promptly notify Borrower thereof through Global Administrative Agent and such Lender's obligation to make or maintain Eurodollar Loans having an affected Interest Period hereunder shall
be suspended until such time as such Lender may again make and maintain Eurodollar Loans having an affected Interest Period (in which case the provisions of Section 2.14(b)hereof shall be
applicable). Before giving such notice pursuant to this Section 2.14, such Lender will designate a different available Applicable Lending Office for the affected Eurodollar Loans of such Lender or
take
such other action as Borrower may request if such designation or action will avoid the need to suspend such Lender's obligation to make Eurodollar Loans hereunder and will not, in the sole opinion of
such Lender exercised in good faith, be disadvantageous to such Lender (provided, that such Lender shall have no obligation so to designate an
Applicable Lending Office for Eurodollar Loans located in the United States of America).

36

---



(b)   If the obligation of any Lender to make or maintain any Eurodollar Loans shall be suspended pursuant to Section 2.14(a)hereof,
all Loans having an affected Interest Period which would otherwise be made by such Lender as Eurodollar Loans shall be
made instead as ABR Loans (and, if such Lender so requests by notice to Borrower with a copy to the Global Administrative Agent, each Eurodollar Loan having an affected Interest Period of such Lender
then outstanding shall be automatically converted into an ABR Loan on the last day of the Interest Period for such Eurodollar Loans unless earlier conversion is required by applicable law) and, to the
extent that Eurodollar Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Eurodollar Loans shall be applied instead to such ABR
Loans.

SECTION
2.15Increased Costs.

(a)   If
any Change in Law shall:



and
the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase
the cost to such Lender or such Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or such Issuing
Bank hereunder (whether of principal, interest or otherwise), then Borrower will pay to such Lender or such Issuing Bank such additional amount or amounts as will compensate such Lender or such
Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b)   If
any Lender or any Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such
Lender's or such Issuing Bank's capital or on the capital of such Lender's or such Issuing Bank's holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in
Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender's or such Issuing Bank's
holding company could have achieved but for such Change in Law (taking into consideration such Lender's or such Issuing Bank's policies and the policies of such Lender's or such Issuing Bank's holding
company with respect to capital adequacy), then Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such
Issuing Bank or such Lender's or such Issuing Bank's holding company for any such reduction suffered.

(c)   A
certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or such Lender's or such
Issuing Bank's holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to Borrower and shall be conclusive absent manifest error. Borrower
shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d)   Failure
or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's or such
Issuing Bank's right to demand such compensation;providedthat Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to
this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies Borrower of the Change in
Law giving rise to such increased costs or reductions and of such Lender's

37

---



or
such Issuing Bank's intention to claim compensation therefor;provided furtherthat, if the Change in Law giving rise to such increased costs or
reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.16Break Funding Payments.In the event of (a) the payment (including prepayment) of any
principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan
other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant
hereto (regardless of whether such notice may be revoked underSection 2.10(b)and is revoked in accordance therewith), or (d) the
assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by Borrower pursuant to Section 2.19then, in any such event,
Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the
case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which
would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event
to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or
continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest
rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the London interbank market. A
certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to Borrower and the Global Administrative Agent and
shall be conclusive absent manifest error. Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

SECTION 2.17Taxes.

(a)   Any
and all payments by or on account of any obligation of Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for
any Indemnified Taxes or Other Taxes;providedthat if Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments,
then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), the Global
Administrative Agent, each Lender or the Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make
such deductions and (iii) Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law; providedthat if a Lender is in default of its
obligations underSection 2.17(e), then Borrower
shall only be obligated to comply with clauses (ii) and (iii) of thisSection 2.17(a)with respect to payments to be made to such Lender.

(b)   In
addition, Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c)   Borrower
shall indemnify the Global Administrative Agent, each Lender and each Issuing Bank, within ten (10) days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by the Global Administrative Agent, such Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any
obligation of Borrower hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any
penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the
relevant Governmental Authority; provided that if a Lender is in default of its obligations underSection 2.17(e), then Borrower shall have no

38

---



obligations
under thisSection 2.17(c)with respect to any payments or liabilities described herein made or owed by such Lender. A certificate as
to the amount of such payment or liability delivered to Borrower by a Lender or an Issuing Bank, or by the Global Administrative Agent on its own behalf or on behalf of a Lender or an Issuing Bank,
shall be conclusive absent manifest error.

(d)   As
soon as practicable after any payment of Indemnified Taxes or Other Taxes by Borrower to a Governmental Authority, if available, Borrower shall deliver to the Global
Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such
payment reasonably satisfactory to the Global Administrative Agent.

(e)   Each
Lender that is not organized under the laws of the United States of America or a state thereof agrees that such Lender will deliver to Borrower and the Global
Administrative Agent two (2) duly completed copies of United States Internal Revenue Service Form W-8 BEN or W-8 ECI certifying in either case that such Lender is
entitled to receive payments from the Loan Parties under the Loan Documents without deduction or withholding of any United States federal income taxes. Each Lender which so delivers a
Form W-8 BEN or W-8 ECI further undertakes to deliver to Borrower and the Global Administrative Agent two (2) additional copies of such form (or a successor form)
on or before such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it and such amendments thereto or extensions or
renewals thereof as may be reasonably requested by Borrower or the Global Administrative Agent, in each case, certifying that such Lender is entitled to receive payments from Borrower under the Loan
Documents without deduction or withholding of any United States federal income taxes, unless (i) an event (including without limitation any change in treaty, law or regulation) has occurred
prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form
with respect to it and (ii) such Lender advises Borrower and the Global Administrative Agent that it is not capable of receiving such payments without any deduction or withholding of United
States federal income tax.

(f)    If
Borrower at any time pays an amount underSection 2.17(a),(b)or(c)to any Lender, the Global Administrative Agent or any Issuing Bank, and such payee receives a refund of or credit for any part of any Indemnified
Taxes or Other Taxes which such payee determines in its sole judgment is made with respect to such amount paid by Borrower, such Lender, the Global Administrative Agent or any Issuing Bank, as the
case may be, shall pay to such Borrower the amount of such refund or credit promptly, and in any event within 60 days, following the receipt of such refund or credit by such payee. Nothing in
this Section shall require any Lender, the Global Administrative Agent or any Issuing Bank to make available its tax returns or any other information relating to its taxes that such Person deems
confidential.

Disbursements, or of amounts payable underSection 2.15,2.16or 2.17, or otherwise) prior to the time
expressly required hereunder or under such other Loan Document for such payment (or, if no such time is expressly
required, prior to 12:00 noon, New York City time), on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date

extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan
Document shall be made in U.S. Dollars.

(b)   If
at any time insufficient funds are received by and available to the Global Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements,
interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance
with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c)   If
any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its
Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued
interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and
participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of
principal of and accrued interest on their respective Loans and participations in LC Disbursements;providedthat (i) if any such participations
are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without
interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by Borrower pursuant to and in accordance with the express terms of this Agreement or any
payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to
Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). Borrower consents to the foregoing and agrees, to the extent it may effectively do so under
applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against Borrower rights of set-off and counterclaim with respect to such
participation as fully as if such Lender were a direct creditor of Borrower in the amount of such participation.

(d)   Unless
the Global Administrative Agent shall have received notice from Borrower prior to the date on which any payment is due to the Global Administrative Agent for the
account of the Lenders or an Issuing Bank hereunder that Borrower will not make such payment, the Global Administrative Agent may assume that Borrower has made such payment on such date in accordance
herewith and may, in reliance upon such assumption, distribute to the Lenders or an Issuing Bank, as the case may be, the amount due. In such event, if Borrower has not in fact made such payment, then
each of the Lenders or each of the Issuing Banks, as the case may be, severally agrees to repay to the Global Administrative Agent forthwith on demand the amount so distributed to such Lender or such
Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Global Administrative Agent, at the greater of
the Federal Funds Effective Rate and a rate determined by the Global Administrative Agent in accordance with banking industry rules on interbank compensation.

(e)   If
any Lender shall fail to make any payment required to be made by it pursuant toSection 2.4(d)or (e),2.5(b),2.18(d)or 10.3(c)then the Global Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts
thereafter
received by the Global Administrative Agent for the account of such Lender to satisfy such Lender's obligations under such Sections until all such unsatisfied obligations are fully paid.

SECTION 2.19Mitigation Obligations; Replacement of Lenders.

(a)   If
any Lender requests compensation underSection 2.15, or if Borrower is required to pay any additional amount to
any Lender or any Governmental Authority for the account of any Lender pursuant toSection 2.17, then such Lender shall use reasonable efforts to
designate a different Applicable Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in
the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant toSection 2.15or 2.17, as
the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)   If
(i) any Lender asserts that events have occurred suspending its obligation to make or maintain Eurodollar Loans under Section 2.14when substantially all other Lenders have not also done so,
(ii) any Lender requests compensation under Section 2.15, (iii) Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any
Lender pursuant toSection 2.17, or (iv) any Lender defaults in its obligation to fund Loans hereunder, then Borrower may, at its sole
expense and effort, upon notice to such Lender and the Global Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the terms of Section 10.4), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee
may be another Lender, if a Lender accepts such assignment);providedthat (1) Borrower shall have received the prior written consent of the
Global Administrative Agent, which consent shall not unreasonably be withheld or delayed, (2) such Lender shall have received payment of an amount equal to the outstanding principal of its
Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or Borrower (in the case of all other amounts), (3) the assignee and assignor shall have entered into an Assignment and Assumption, and (4) in the case of any
such assignment resulting from a claim for compensation underSection 2.15or payments required to be made pursuant to Section 2.17, such
assignment will result in a reduction in such compensation or payments.

SECTION 2.20Addition of Lenders and Increase in Commitments.It is agreed by the parties hereto that one
or more financial institutions acceptable to Borrower and the Global Administrative Agent may become a Lender under this Agreement, with the consent of the Global Administrative Agent (as to the
identity of the institution), or a Lender may increase its Commitment by executing and delivering to Borrower and the Global Administrative Agent a certificate substantially in the form of Exhibit Bhereto (a "Lender Certificate"). Each Lender shall have the option, but no Lender shall
have any obligation, to increase its Commitment hereunder in connection with any increase in Commitments pursuant to this Section. Upon receipt and agreement by Borrower and the Global Administrative
Agent (as to the identity of the institution) of any such Lender Certificate, (a) the aggregate amount of the Commitments of the Lenders (including any Person that becomes a Lender by delivery
of such a Lender Certificate) automatically without further action by Borrower, the Global Administrative Agent or any Lender shall be increased by the amount indicated in such Lender Certificate (but
not in excess of U.S.$1,800,000,000 in the aggregate for all such increases pursuant to this Section and the Equivalent Amount in U.S. Dollars of increases pursuant to Section 2.21 of the
Canadian Credit Agreement) on the effective date set forth in such Lender Certificate (such increased

reflect the increase in the Commitment of an existing Lender, and the Applicable Percentages of the Lenders shall be adjusted accordingly to reflect the additional Lender or the increase in the
Commitment of an existing Lender, (c) any such additional Lender shall be deemed to be a party in all respects to this Agreement and any other Loan Documents to which the Lenders are a party,
and (d) upon the effective date set forth in such Lender Certificate, any such Lender party to the Lender Certificate shall purchase a pro rata portion of the outstanding Credit Exposure of
each of the current Lenders such that the Lenders (including any additional Lender, if applicable) shall have the appropriate portion of the aggregate outstanding Credit Exposure of the Lenders (based
in each case of such Lender's Applicable Percentage, as revised pursuant to this Section).

increased the likelihood of, a Material Adverse Effect.

SECTION 3.7Compliance with Laws and Agreements.Each of Borrower and its Restricted Subsidiaries is in
compliance with all Governmental Rules applicable to such Person or its Property and all indentures, agreements and other instruments binding upon it or its Property, except where the failure to do

the Global Administrative Agent or the Majority Lenders may reasonably request, to effect the transactions contemplated by the Loan Documents or to grant, preserve, protect or perfect the Liens
created or intended to be created by the Security Documents or the validity or priority of any such Lien, all at the expense of the Loan Parties. Borrower also agrees to provide to the Global
Administrative Agent, from time to time upon reasonable request of the Global Administrative Agent, information which is in the possession of Borrower or its Restricted Subsidiaries or otherwise

herein and in the Canadian Credit Agreement) from its Subsidiary Guaranty and its Guaranty (as defined in the Canadian Credit Agreement);provided, further,
 that if, after such release of any or all Loan Parties under the Security Documents, Borrower's Issuer Rating subsequently falls such that the
Issuer Rating issued by both S&P and Moody's is "BB+" and "Ba1," respectively, or lower, then Borrower will, and will cause each other Loan Party to, re-execute and re-deliver
to the Global Administrative Agent any and all Security Documents that are required to be delivered pursuant to the terms and provisions of this Agreement and the Canadian Credit Agreement.

(b)   Borrower
hereby authorizes the Global Administrative Agent and the Lenders to file one or more financing or continuation statements, and amendments thereto, relative to

information with respect thereto.

Borrower and its Restricted Subsidiaries located in the United States and subject to a mortgage Lien having a Present Value that is less than 1.875 times the amount of the Allocated U.S. Borrowing

acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a
party hereto and to the other Loan Documents and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the
assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement and the other Loan Documents (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 ofSections 2.15,2.16,2.17, 2.18
and10.3and be subject to the terms of Section 10.12). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does
not comply with this paragraph
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 paragraph (e) of this Section.

(c)   The
Global Administrative Agent, acting for this purpose as an agent of Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment
and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and LC Disbursements owing to,
each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and Borrower, the Global
Administrative Agent, the Issuing Banks 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 and the other Loan Documents, notwithstanding notice to the contrary. The Register shall be available for inspection by Borrower, any Issuing Bank and any Lender, at any reasonable time and
from time to time upon reasonable prior notice.

therein in the Register and will provide prompt written notice to Borrower of the effectiveness of such assignment. No assignment shall be effective for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.

(e)   Any
Lender may, without the consent of Borrower, the Global Administrative Agent or any Issuing Bank, sell participations to one or more banks or other entities (a
"Participant") in all or a portion of such Lender's rights and obligations under this Agreement (including all or a portion of its Commitment and the
Loans owing to it);providedthat (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) Borrower, the Global Administrative Agent, the Issuing Banks 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 the Loan Documents and to approve any amendment, modification or waiver of any provision of the Loan Documents; providedthat such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver described in the second proviso toSection 10.2(b)that affects such Participant. Subject to paragraph (f) of this
Section, Borrower agrees that each Participant shall be entitled to the benefits ofSections 2.15,2.16and2.17to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the
extent permitted by law, each Participant also shall be entitled to the benefits ofSection 10.8and 10.12as though it were a Lender, provided such
Participant agrees to be subject to Section 2.18(c)as though it were a Lender.

(f)    A Participant shall not be entitled to receive any greater payment underSection 2.15, 2.16or2.17than the applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17unless Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of Borrower,
to comply withSection 2.17(e)as though it were a Lender.

(g)   Any
Lender may at any time pledge or assign a Lien in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or
assignment to secure obligations to a Federal Reserve Bank or, in the case of a Lender organized in a jurisdiction outside of the United States, a comparable Person, and this Section shall not apply
to any such pledge or assignment of a security interest;providedthat no such pledge or assignment of a security interest shall release a Lender from
any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION
10.5Survival.All covenants, agreements, representations and warranties made by the Loan Parties in the
Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the
other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any
such other party or on its behalf and notwithstanding that any Agent, any Issuing Bank, the Arranger or any Lender may have had notice or knowledge of any Default or incorrect representation or
warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount
payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.15,2.16,2.17, 2.18,10.3and10.12and Article IXshall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the

Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a

jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the
remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION
10.8Right of Setoff.If an Event of Default shall have occurred and be continuing, each of the Agents,
the Issuing Banks, the Lenders and their Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general
or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of Borrower or any of its
Restricted Subsidiaries against any and all the obligations of Borrower now or hereafter existing under

to such Lender, such Issuing Bank or Agent limiting rates of interest which may be charged or collected by such Lender, such Issuing Bank or Agent. Accordingly, if the transactions contemplated hereby
or thereby would be illegal, unenforceable, usurious or criminal under laws applicable to a Lender, any Issuing Bank or any Agent (including the laws of any jurisdiction whose laws may be mandatorily

provisions of this Section shall govern and control;

(b)   the
aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received under this Agreement or
any Loan Document or otherwise in connection with this Agreement or any Loan Document by such Lender, such Issuing Bank or such Agent shall under no circumstances exceed the maximum amount of interest

Lender, such Issuing Bank or such Agent hereunder or under any Loan Document shall, to the extent permitted by laws applicable to such Lender, such Issuing Bank or such Agent, as the case may be, be
amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof;

(d)   if
at any time the interest provided pursuant to this Section or any other clause of this Agreement or any other Loan Document, together with any other fees or
compensation payable pursuant to this Agreement or any other Loan Document and deemed interest under laws applicable to such Lender, such Issuing Bank or such Agent, exceeds that amount which would
have accrued at the Highest Lawful Rate, the amount of interest and any such fees or compensation to accrue to such Lender, such Issuing Bank or such Agent pursuant to this Agreement or such other
Loan Document shall be limited, notwithstanding anything to the contrary in this Agreement or any other Loan Document, to that amount which would have accrued at the Highest Lawful Rate, but any
subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender, such Issuing Bank or such Agent pursuant to this Agreement or such other Loan Document below the Highest
Lawful Rate until the total amount of interest accrued pursuant to this Agreement or such other Loan Document, as the case may be, and such fees or compensation deemed to be interest equals the amount
of interest which would have accrued to such Lender or Agent if a varying rateper annumequal to the interest provided pursuant to any other relevant
Section hereof (other than this Section) or thereof, as applicable, had at all times been in effect,plusthe amount of fees which would have been

(e)   with
the intent that the rate of interest herein shall at all times be lawful, and if the receipt of any funds owing hereunder or under any other agreement related
hereto (including any of the other Loan Documents) by such Lender, such Issuing Bank or such Agent would cause such Lender to charge Borrower a criminal rate of interest, the Lenders, the Issuing
Banks and the Agents agree that they will not require the payment or receipt thereof or a portion thereof which would cause a criminal rate of interest to be charged by such Lender, such Issuing Bank
or such Agent, as applicable, and if received such affected Lender, such Issuing Bank or Agent will return such funds to Borrower so that the rate of interest paid by Borrower shall not exceed a
criminal rate of interest from the date this Agreement was entered into.
