ARTICLE II

The Credits

SECTION 2.1 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make Loans in U.S. Dollars to the 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 U.S. Revolving 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, the Borrower may borrow, prepay and reborrow Loans.

SECTION 2.2 Loans 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; provided that 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 to Sections 2.13 and 2.14, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the 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; provided that any exercise of such option shall not affect the obligation of the 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.$5,000,000 (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.$500,000 and not less than U.S.$500,000 (including any continuation or conversion of existing Loans made in connection therewith); provided that 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; provided that there shall not at any time be more than a total of seven (7) Eurodollar Borrowings outstanding.

(d) Notwithstanding any other provision of this Agreement, the 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 2.3 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Global Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 2:00 p.m., New York City time, three (3) 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 the Borrower, substantially in the form of Exhibit E-1 or otherwise in a form approved by the Global Administrative Agent. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 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 the 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 2.4 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own account or the account of any 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 the Borrower to, or entered into by the 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), the 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 with paragraph (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, the 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 the 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 U.S.$25,000,000 and (ii) the total Credit Exposure shall not exceed the lesser of (x) the aggregate Commitments of the Lenders or (y) the U.S. Revolving Borrowing Base then in effect.

(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, provided such date is not beyond the date in clause (ii)) 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 the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the 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, the 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 the 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 the 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 the Borrower receives such notice; provided that, unless such LC Disbursement is

less than U.S.$500,000, the Borrower may, subject to the conditions to Borrowing set forth herein, request in accordance with Section 2.3 that such payment be financed with a Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Borrowing. If the Borrower fails to make such payment when due, the Global Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the 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 the Borrower, in the same manner as provided in Section 2.5 with respect to Loans made by such Lender (and Section 2.5 shall 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 the Borrower pursuant to this paragraph, 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 the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The 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 term or provision 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, the 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; provided that the foregoing shall not be construed to excuse such Issuing Bank from liability to the 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 the Borrower to the extent permitted by applicable law) suffered by the 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 the 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; provided that any failure to give or delay in giving such notice shall not relieve the 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 the 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 the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if the Borrower fails to reimburse such LC Disbursement within two (2) Business Days after such reimbursement is due pursuant to paragraph (e) of this Section, then Section 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 Lender pursuant to paragraph (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 the Borrower receives notice from the Global Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this paragraph, the 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; provided that 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 the Borrower described in Section 8.1(g). The 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 with Section 2.10. Each such deposit shall be held by the Global Administrative Agent as collateral for the payment and performance of the obligations of the 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 the 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 the 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 the Borrower under this Agreement. If the 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 the Borrower within three (3) Business Days after all Events of Default have been cured or waived. If the Borrower is required to provide an amount of cash collateral hereunder pursuant to Section 2.10, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower as and to the extent that, after giving effect to such return, the Borrower would remain in compliance with Section 2.10 and no Default shall have occurred and be continuing.

SECTION 2.5 Funding 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 12:00 noon, 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 the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Global Administrative Agent in New York City; provided that 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 the 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 the Borrower severally agree to pay to the 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 the 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 the 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 2.6 Interest Elections.

(a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request (or an ABR Borrowing if no Type is specified) and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request (or one month if no Interest Period is specified). Thereafter, the Borrower may elect to convert such 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. The Borrower may, subject to the requirements of Section 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, the Borrower shall notify the Global Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.3 if the 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 the Borrower, substantially in the form of Exhibit E-2 or 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:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

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

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the 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 the 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 Required Lenders, so notifies the 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 Obligations have been accelerated pursuant to Section 8.3, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.7 Global Borrowing Base.

(a) Initial Global Borrowing Base. 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 the Borrower and its Subsidiaries (including the Canadian Borrowers) and agreed to by the Combined Lenders to be U.S.$425,000,000; provided, however, that in the event that the Borrower or any of its Subsidiaries incurs Senior Debt or Subordinated Debt (other than the Bridge Loan) prior to the date of the Initial Borrowing, the Global Borrowing Base and the initial U.S. Revolving Borrowing Base will be reduced as provided for in Section 2.7(g).

(b) Annual Scheduled Determinations of the Global Borrowing Base. Promptly after January 1st of each calendar year (commencing January 1, 2004), and in any event prior to March 1st of each calendar year, the Borrower shall furnish to the Global Administrative Agent and the Combined Lenders a Reserve Report in form and substance reasonably satisfactory to the Global Administrative Agent, which report shall evaluate as of December 31st of the immediately preceding calendar year the Proven Reserves attributable to the Oil and Gas Properties which the 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 the Borrower hereunder, and 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 fifteen (15) days following their receipt of the proposed amount for the redetermined Global Borrowing Base, (x) the Super Majority Lenders if the proposed amount is an increase or (y) the Required Lenders if the proposed amount is a decrease or maintenance, 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, however that failure by any Combined Lender to reject in writing the Global Administrative Agent’s determination of the Global Borrowing Base within said fifteen (15) day period shall be deemed an acceptance of such determination by such Combined Lender. If the Super Majority Lenders

or the Required Lenders, as applicable, 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 Super Majority Lenders if such number would result in an increase in the Global Borrowing Base or otherwise, the 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 Super Majority Lenders or the Required Lenders, as applicable, of the Global Borrowing Base, the Global Administrative Agent upon notice thereof shall, by written notice to the Borrower, and the Combined Lenders, designate the new Global Borrowing Base available to the Borrower, the Canadian Revolving Borrowers and the Canadian Term Borrower (each such notice in this Section 2.7(b), a “Global Borrowing Base Designation Notice”). The Global Borrowing Base Designation Notice shall also set forth the then applicable Revolving Borrowing Base as determined by the Global Administrative Agent. If the Combined Revolving Commitments are in effect and/or any Combined Revolving Obligations are outstanding, then upon receipt of such Global Borrowing Base Designation Notice, the Borrower shall designate the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base to the Global Administrative Agent in accordance with Section 2.7(d).

(d) Allocation of the Revolving Borrowing Base. For so long as any of the Combined Revolving Commitments are in effect and/or any Combined Revolving Obligations are outstanding, the Revolving Borrowing Base shall be comprised of the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base, and allocations between the U.S. Revolving Borrowing Base and Canadian Revolving Borrowing Base shall be made in accordance with this Section 2.7(d).

(i) The “U.S. Revolving Borrowing Base” means, as of any date, the amount in U.S. Dollars designated or determined as such from time to time (A) by the Borrower pursuant to a Revolving Borrowing Base Allocation Notice delivered in accordance with Section 2.7(d)(iii) of this Agreement or (B) in accordance with the other provisions of this Agreement. The U.S. Revolving Borrowing Base shall represent the maximum amount of credit in the form of Loans and Letters of Credit (subject to the aggregate Commitments and subject to the other provisions thereof) that the Lenders will extend to the Borrower at any one time prior to the Maturity Date. On the date of this Agreement, the initial U.S. Revolving Borrowing Base shall be U.S.$290,000,000.

(ii) The “Canadian Revolving Borrowing Base” means, as of any date, the Equivalent Amount in U.S. Dollars designated as such from time to time (A) by the Borrower pursuant to a Revolving Borrowing Base Allocation Notice delivered in accordance with Section 2.7(d)(iii) of this Agreement or (B) in accordance with the other provisions of this Agreement. The Canadian Revolving Borrowing Base shall represent the maximum amount of credit in the form of “Loans”, “Letters of Credit” and “Bankers’ Acceptances” in each case as defined in the Canadian Revolving Credit Agreement (subject to the aggregate “Commitments” as defined in the Canadian Revolving Credit

Agreement and subject to the other provisions thereof) that the Canadian Revolving Lenders will extend to the Canadian Revolving Borrowers at any one time prior to the “Maturity Date” as defined in the Canadian Revolving Credit Agreement. On the date of this Agreement, the initial Canadian Revolving Borrowing Base shall be U.S.$25,000,000.

(iii) Upon receipt of the Global Borrowing Base Designation Notice and the Revolving Borrowing Base set forth therein, the Borrower shall specify within ten (10) days of its receipt thereof the allocation of the Revolving Borrowing Base between the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base by providing a written notice to the Global Administrative Agent of such allocation (each such notice herein a “Revolving Borrowing Base Allocation Notice”); provided that the sum of the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base shall at all times be equal to the Revolving Borrowing Base. In the event that the Borrower fails to provide the Global Administrative Agent with a Revolving Borrowing Base Allocation Notice within the period required by this Section 2.7(d)(iii), the Revolving Borrowing Base will be allocated in same proportion as existed prior to such redetermination. Promptly upon the allocation of the Revolving Borrowing Base between the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base in accordance with the procedures set forth above, the Global Administrative Agent shall provide a written notice to the Combined Revolving Lenders and the Borrower, which written notice shall set forth the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base to be in effect. Any designation of the U.S. Revolving Borrowing Base or the Canadian Revolving Borrowing Base effected pursuant to this Section 2.7(d)(iii) in connection with a determination or redetermination of the Global Borrowing Base shall be effective as of the date of the Global Borrowing Base Designation Notice.

(e) Discretionary Determination of the Global Borrowing Base. Each of (i) the Global Administrative Agent or the Majority Lenders in the event that Global Borrowing Base Utilization exceeds 50% at any time for a period of greater than fifteen (15) consecutive Business Days or (ii) (A) the Borrower or (B) the Global Administrative Agent, at the request of the Required Lenders, shall have the right to request in writing a redetermination of the Global Borrowing Base, in its sole discretion at any time and from time to time, provided, that clause (i) and clause (ii) may each be the basis of an unscheduled redetermination not more often than one (1) time during any calendar year. If any Person shall request discretionary redetermination of the Global Borrowing Base pursuant to the provisions of this Section 2.7(e), the Borrower shall within 30 days of receipt of a request therefor from the Global Administrative Agent, deliver to the Global Administrative Agent a Reserve Report dated as of the date requested in such notice and such updated engineering, production, operating and other data as the Global Administrative Agent or any other Combined Lender may reasonably request. The Super Majority Lenders if such number would result in an increase in the Global Borrowing Base or otherwise, the 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 the Borrower shall provide a Revolving Borrowing Base Allocation Notice to the Global Administrative Agent in accordance with Section 2.7(d)(iii); provided that in the event that the Borrower fails to provide such Revolving Borrowing Base Allocation Notice, the Revolving Borrowing Base shall be allocated

between the U.S. Revolving Borrowing Base and Canadian Revolving 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 Super Majority Lenders or Required Lenders, as applicable, taking into consideration the estimated value of the Oil and Gas Properties owned by the Borrower and its 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 other Combined Lender, all in accordance with the other provisions of this Section 2.7 in 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.$425,000,000, 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 to Section 2.7(b) (annual) and Section 2.7(e) (unscheduled) and may be adjusted from time to time to give effect to issuances of Senior Debt or Subordinated Debt under Section 2.7(g) and the occurrence of Casualty Events under Section 2.7(h). 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, Revolving Borrowing Base Deficiency or a U.S. Borrowing Base Deficiency exists, the Global Administrative Agent shall give written notice thereof to the Borrower and the date such notice is received shall be the “Deficiency Notification Date”.

(g) Issuance of Senior Debt and Subordinated Debt. In the event that the Borrower or any of its Subsidiaries incurs any Senior Debt (other than Non-Recourse Debt) on the date of or after the Initial Borrowing, then the Global Borrowing Base and the U.S. Revolving Borrowing Base shall each be reduced immediately by an amount equal to 100% of the stated principal amount of such Senior Debt; provided, however, that no reduction in the U.S. Revolving Borrowing Base pursuant to this Section 2.7(g) attributable to the issuance of Senior Debt shall be effected to the extent that the proceeds of the issuance of such Senior Debt are used to repay or prepay, as the case may be, the “Loans” under the Canadian Term Credit Agreement; and provided, further, that if thereafter the U.S. Revolving Borrowing Base is, or is reduced to, $0, the Canadian Revolving Borrowing Base shall be reduced immediately by an amount equal to (A) 100% of the stated principal amount of such Senior Debt less (B) the amount by which the U.S. Revolving Borrowing Base was reduced pursuant to this Section 2.7(g) as a result of the issuance of such Senior Debt. In the event that the Borrower or any of its Subsidiaries incurs any Subordinated Debt (other than Non-Recourse Debt) on the date of or after the Initial Borrowing, then the Global Borrowing Base and the U.S. Revolving Borrowing Base shall each be reduced immediately by an amount equal to 30% of the stated principal amount of such Subordinated Debt; provided, however, that no reduction in the U.S. Revolving Borrowing Base pursuant to this Section 2.7(g) attributable to the issuance of Subordinated Debt shall be effected to the extent that the proceeds of the issuance of such Subordinated Debt are used to repay or prepay, as the case may be, the “Loans” under the Canadian Term Credit Agreement; and provided, further, that the Indebtedness evidenced by the Bridge Loan shall not be included in the foregoing calculations until after the date of the first scheduled redetermination of the Global Borrowing Base; and provided, further, that if the U.S. Revolving Borrowing Base is, or is

reduced to, $0, the Canadian Revolving Borrowing Base shall be reduced immediately by an amount equal to (A) 30% of the stated principal amount of such Subordinated Debt less (B) the amount by which the U.S. Revolving Borrowing Base was reduced pursuant to this Section 2.7(g) as a result of the issuance of such Subordinated Debt.

(h) Casualty Event. In the event that a Casualty Event has occurred related to any Borrowing Base Property, to the extent that the Net Cash Proceeds received by the Borrower or any of its 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 90 days after the occurrence thereof, the Global Administrative Agent, at the request of the Required Lenders, shall have the right to reduce the U.S. Revolving Borrowing Base and, if applicable, the Canadian Revolving Borrowing Base, in its sole discretion based on its review of such Casualty Event, in the manner set forth in this Section 2.7(h); provided that the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base shall not together be reduced by an amount greater than 100% of such Net Cash Proceeds. The Global Administrative Agent shall provide notice to the Borrower and the Combined Lenders and the other Agents of the reduction, first, in the U.S. Revolving Borrowing Base resulting from such Casualty Event, which reduction shall be effective as of the date of such notice; provided that once the U.S. Revolving Borrowing Base is reduced to $0, then any additional required reduction shall be made to the Canadian Revolving Borrowing Base.

SECTION 2.8 Termination and Reduction of Commitments.

(a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(b) The Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of U.S.$1,000,000 and not less than U.S.$5,000,000 and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the aggregate Credit Exposure of the Lenders would exceed the aggregate Commitments of the Lenders.

(c) The Borrower shall notify the Global Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least two (2) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Global Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Global Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their Applicable Percentage of the Commitments.

(d) The Borrower will not terminate, or permit to expire, all of the Commitments under this Agreement prior to (i) the expiration or termination of the Canadian Revolving Commitments and (ii) the payment and performance in full of all Canadian Revolving Obligations.

SECTION 2.9 Repayment of Loans; Evidence of Indebtedness.

(a) The Borrower hereby unconditionally promises to pay to the Global Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan and Borrowing of such Lender on the Maturity Date.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the Obligations of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Global Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Global Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to paragraphs (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Global Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the 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, the 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 to Section 10.4) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if any such promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.10 Prepayment of Loans.

(a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of Section 2.10(c).

(b) If, (i) either the Global Borrowing Base, Revolving Borrowing Base or the U.S. Revolving Borrowing Base is (A) redetermined or reallocated under Section 2.7, (B) reallocated pursuant to Section 2.7(d), or (C) reduced pursuant to any other provision of this Agreement, and (ii) as a result thereof, either a Global Borrowing Base Deficiency, Revolving Borrowing Base

Deficiency or a U.S. Borrowing Base Deficiency occurs, then the Borrower shall take the following actions:

(1) in the case of a Global Borrowing Base Deficiency or a Revolving Borrowing Base Deficiency resulting from a redetermination or reduction of the Global Borrowing Base, prepay, or cause to be prepaid, Loans and “Loans” under the Canadian Revolving Credit Agreement in an aggregate principal amount equal to such deficiency, together, in each case, with interest on the principal amount paid accrued to the date of such prepayment and, if after prepaying all of such Loans and “Loans” under the Canadian Revolving Credit Agreement, a Global Borrowing Base Deficiency or a Revolving Borrowing Base Deficiency remains as a result of an LC Exposure, pay to the Global Administrative Agent an amount equal to such remaining Global Borrowing Base Deficiency or Revolving Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.4(i); provided that the Borrower shall be obligated to make (or cause to be made) any such prepayment and/or deposit of cash collateral within 180 days following the Deficiency Notification Date with respect to such deficiency, and provided further that within 90 days following the Deficiency Notification Date, the Borrower shall have prepaid (or caused to be prepaid), or deposited cash in an amount equal to, one-half of such Global Borrowing Base Deficiency or Revolving Borrowing Base Deficiency;

(2) in the case of a U.S. Borrowing Base Deficiency resulting from a redetermination or reduction of the Global Borrowing Base, take the action described under clause (1) above (except that prepayments shall be made in respect of Loans made pursuant to this Agreement);

(3) in the case of a U.S. Borrowing Base Deficiency resulting from a reallocation of the Revolving Borrowing Base pursuant to Section 2.7(d), prepay Loans in an aggregate principal amount equal to such deficiency, together with interest on the principal amount paid accrued to the date of such prepayment, and if a U.S. Borrowing Base Deficiency remains after prepaying all of the Loans as a result of an LC Exposure, pay to the Global Administrative Agent an amount equal to such remaining U.S. Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.4(i); it being understood that the Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the effective date of such reallocation;

(4) in the case of a U.S. Borrowing Base Deficiency resulting from an incurrence of Senior Debt or Subordinated Debt pursuant to Section 2.7(g), utilize the proceeds of such Senior Debt or Subordinated Debt, as applicable, to take the action required under clause (1) above (except that (i) the Borrower shall not be obligated to make any prepayments in respect of “Loans” under the Canadian Term Credit Agreement and (ii) prepayments shall first be made in respect of Loans made pursuant to this Agreement); provided that if a prepayment or deposit is required under this clause (4), then the Borrower shall be obligated to make (or cause to be made) such prepayment and/or deposit of cash collateral

contemporaneously with the incurrence of such Senior Debt or Subordinated Debt;

(5) notwithstanding anything in this Section 2.10 to the contrary, in the event that a U.S. Borrowing Base Deficiency exists at a time when no Revolving Borrowing Base Deficiency exists, then, to the extent that such action would cure (in whole or in part) such U.S. Borrowing Base Deficiency, the Borrower may reallocate the Revolving Borrowing Base between the U.S. Revolving Borrowing Base and the Canadian Revolving Borrowing Base by providing the Global Administrative Agent with its election to do so (which election will designate the relevant reallocations) on the Business Day on which such U.S. Borrowing Base Deficiency occurs; provided, however, that no reallocation shall be permitted to the extent such reallocation would cause the aggregate “Credit Exposure” of the Canadian Revolving Lenders under the Canadian Revolving Credit Agreement to be greater than the lesser of the aggregate “Commitments” thereunder and the Canadian Revolving Borrowing Base; and

(6) in the case of a U.S. Borrowing Base Deficiency resulting from a Casualty Event pursuant to Section 2.7(h), utilize the Net Cash Proceeds of such Casualty Event to take the action described under clause (1) above (except that (i) the Borrower shall not be obligated to make any prepayments in respect of “Loans” under the Canadian Term Credit Agreement and (ii) prepayments shall first be made in respect of Loans made pursuant to this Agreement); provided that if a prepayment or deposit is required under this clause (6), then the Borrower shall be obligated to make (or cause to be made) such prepayment and/or deposit of cash collateral on the Business Day immediately following the Deficiency Notification Date with respect to such deficiency.

(c) The Borrower shall notify the Global Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 1:00 p.m., New York City time, two (2) Business Days before the date of prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid (which amount shall be in a minimum principal amount of U.S.$1,000,000 and in U.S.$1,000,000 increments in excess thereof); provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.8, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.8. Promptly following receipt of any such notice relating to a Borrowing, the Global Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.2. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.12 and by any other amounts then due under this Agreement (including all amounts due under Section 2.16).

SECTION 2.11 Fees.

(a) The Borrower agrees to pay to the Global Administrative Agent for the account of each Lender a commitment fee (the “Commitment Fee”), which shall accrue at the Applicable Rate on the daily amount equal to the Applicable Percentage of such Lender of the Unutilized Commitment during the period from and including the Global Effective Date to but excluding the date on which the Commitments terminate. Accrued Commitment Fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the date of this Agreement; provided that any Commitment Fees accruing after the date on which the Commitments terminate shall be payable on demand. All Commitment Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) The Borrower agrees to pay (i) to the Global Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate as interest on Eurodollar Loans on the average daily amount of such Lender’s Applicable Percentage of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date on which the Commitments terminate and the date on which the Lenders cease to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee equal to the greater of (A) U.S.$500 and (B) the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with respect to the administration, issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees shall be payable in arrears on the last day of each March, June, September and December of each year, commencing on the first such date to occur after the date of this Agreement; provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within ten (10) days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) The Borrower agrees to pay to the Global Administrative Agent, for its own account, the account of the Agents and for the account of each Lender, as applicable, fees, including, without limitation, an upfront fee (the “Upfront Fee”), in the amounts and at the times separately agreed upon between the Borrower, the Global Administrative Agent and the Global Syndication Agents, including, without limitation, the amounts agreed upon in the Fee Letter.

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Global Administrative Agent (or the Issuing Bank, in the case of fees payable to it) for distribution, in the case of Commitment Fees and participation fees, to the Lenders entitled thereto. Fees paid shall not be refundable under any circumstances.

SECTION 2.12 Interest.

(a) Subject to Section 10.13, the Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate for ABR Loans.

(b) Subject to Section 10.13, the Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate for Eurodollar Loans.

(c) Notwithstanding the foregoing, but subject to Section 10.13, if any principal of or interest on any Loan or any fee or other amount payable by the 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 judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section plus, to the extent permitted by applicable law, 2% or (ii) in the case of any other amount, the rate applicable to ABR Loans as provided in paragraph (a) of this Section plus, to the extent permitted by applicable law, 2%.

(d) Subject to Section 10.13, accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand of the Global Administrative Agent or the Majority Lenders (through the Global Administrative Agent), (ii) in the event of any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e) Subject to Section 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). Promptly after the determination of any interest rate provided for herein or any change therein, the Global Administrative Agent shall notify the Lenders to which such interest is payable and the Borrower thereof. Each determination by the Global Administrative Agent of an interest rate or fee hereunder shall, except in cases of manifest error, be final, conclusive and binding on the parties.

SECTION 2.13 Alternate 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 the Borrower,

then the Global Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Global Administrative Agent notifies the 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 2.14 Illegality.

(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 the Borrower thereof through the 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 the 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).

(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 the 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 2.15 Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or any Issuing Bank; or

(ii) impose on any Lender or any Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

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 the 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 the 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 the Borrower and shall be conclusive absent manifest error. The 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; provided that the 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 the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further that, 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 2.16 Break 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 under Section 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 the Borrower pursuant to Section 2.19 then, in any such event, the 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 the Borrower and the Global Administrative Agent and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

SECTION 2.17 Taxes.

(a) Any and all payments by or on account of any obligation of the 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; provided that if the 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 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) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law; provided that if a Lender is in breach of its obligations under Section 2.17(e), then the Borrower shall only be obligated to comply with clauses (ii) and (iii) of this Section 2.17(a) with respect to payments to be made to such Lender.

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

(c) The 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 the 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 breach of its obligations under Section 2.17(e), then the Borrower shall have no obligations under this Section 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 the 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 the Borrower to a Governmental Authority, if available, the 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 the 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 (or if such forms are no longer required, a representation by such Lender) 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 the 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 the Borrower or the Global Administrative Agent, in each case, certifying that such Lender is entitled to receive payments from the 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 the 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 the Borrower at any time pays an amount under Section 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 the Borrower, such Lender, the Global Administrative Agent or any Issuing Bank, as the case may be, shall pay to the 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.

SECTION 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16 or 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 may, in the discretion of the Global Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Global Administrative Agent c/o JPMorgan Chase Bank, Loan and Agency Services, ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇ ▇▇▇▇▇▇, Telephone: ▇▇▇-▇▇▇-▇▇▇▇, Fax: ▇▇▇-▇▇▇-▇▇▇▇, except payments to be made directly to an Issuing Bank as expressly provided herein and payments pursuant to Sections 2.15, 2.16, 2.17(c) and 10.3 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made to the Persons specified therein. The Global Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. Except as set forth in clause (a) of the definition of “Interest Period”, if any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be 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; provided that (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 the 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 the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The 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 the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Global Administrative Agent shall have received notice from the 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 the Borrower will not make such payment, the Global Administrative Agent may assume that the 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 the 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 to Section 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 2.19 Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the

account of any Lender pursuant to Section 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 to Section 2.15 or 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. The 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 2.14 when substantially all other Lenders have not also done so, (ii) any Lender requests compensation under Section 2.15, (iii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or (iv) any Lender defaults in its obligation to fund Loans hereunder, then the 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 restrictions contained in 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); provided that (1) the 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 the Borrower (in the case of all other amounts), (3) the assignee and assignor shall have entered into an Assignment and Acceptance, and (4) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments.

SECTION 2.20 Currency Conversion and Currency Indemnity.

(a) Payments in Agreed Currency. The Borrower shall make payment relative to any Obligation in the currency (the “Agreed Currency”) in which the Obligation was effected. If any payment is received on account of any Obligation in any currency (the “Other Currency”) other than the Agreed Currency (whether voluntarily or pursuant to an order or judgment or the enforcement thereof or the realization of any Collateral or the liquidation of the Borrower or otherwise howsoever), such payment shall constitute a discharge of the liability of the Borrower hereunder and under the other Loan Documents in respect of such obligation only to the extent of the amount of the Agreed Currency which the relevant Lender or Agent, as the case may be, is 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) Conversion of Agreed Currency into Judgment Currency. If, for the purpose of obtaining or enforcing judgment in any court in any jurisdiction, it becomes necessary to convert into a particular currency (the “Judgment Currency”) any amount due in the Agreed Currency

then the conversion shall be made on the basis of the rate of exchange prevailing on the next Business Day following the date such judgment is given and in any event the Borrower shall be obligated to pay the Agents and the Lenders any deficiency in accordance with Section 2.20(c). For the foregoing purposes “rate of exchange” means the rate at which the relevant Lender or Agent, as applicable, in accordance with its normal banking procedures is able on the relevant date to purchase the Agreed Currency with the Judgment Currency after deducting any premium and costs of exchange.

(c) Circumstances Giving Rise to Indemnity. To the fullest extent permitted by applicable law, if (i) any Lender or any Agent receives any payment or payments on account of the liability of the Borrower hereunder pursuant to any judgment or order in any Other Currency, and (ii) the amount of the Agreed Currency which the relevant Lender or Agent, as applicable, is able to purchase on the Business Day next following such receipt with the proceeds of such payment or payments in accordance with its normal procedures and after deducting any premiums and costs of exchange is less than the amount of the Agreed Currency due in respect of such liability immediately prior to such judgment or order, then the Borrower on demand shall, and the Borrower hereby agrees to, indemnify the Lenders and the Agents from and against any loss, cost or expense arising out of or in connection with such deficiency.

(d) Indemnity Separate Obligation. To the fullest extent permitted by applicable law, the agreement of indemnity provided for in Section 2.20(c) shall constitute an obligation separate and independent from all other obligations contained in this Agreement, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by the Lenders or Agents 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 III

SECTION 3.2 Financial Condition. The audited consolidated balance sheet of the Borrower and its Consolidated Subsidiaries as at December 31, 2002 and the related consolidated statement of income, stockholders’ equity and cash flow of the Borrower and its Consolidated Subsidiaries for the fiscal year ended on said date, with the opinion thereon of KPMG LLP

heretofore furnished to each of the Lenders and the unaudited consolidated balance sheet of the Borrower and its Consolidated Subsidiaries as at March 31, 2003 and their related consolidated statements of income, stockholders’ equity and cash flow of the Borrower and its Consolidated Subsidiaries for the three month period ended on such date heretofore furnished to the Global Administrative Agent, are complete and correct and fairly present, in all material respects, the consolidated financial condition of the Borrower and its Consolidated Subsidiaries as at said dates and the results of its operations for the fiscal year and the nine month period on said dates, all in accordance with GAAP, as applied on a consistent basis (subject, in the case of the interim financial statements, to normal year-end adjustments). The pro forma balance sheet of the Borrower as of March 31, 2003 delivered to the Global Administrative Agent and prepared giving effect to the Acquisition (i) has been prepared in good faith in accordance with GAAP, (ii) is based upon assumptions believed to be reasonable and (iii) presents fairly, in all material respects, the unaudited, pro forma financial position of the Borrower and its Subsidiaries as of March 31, 2003. Neither the Borrower nor any Consolidated Subsidiary has on the Closing Date or the Global Effective Date any material Indebtedness, contingent liabilities, liabilities for taxes, unusual forward or long-term commitments or unrealized or anticipated losses from any unfavorable commitments, except as referred to or reflected or provided for in the Financial Statements. Since March 31, 2003, there has been no change or event which could reasonably be expected to have a Material Adverse Effect.

SECTION 3.4 No Breach. Neither the execution and delivery of the Combined Loan Documents, nor compliance with the terms and provisions hereof will conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective Organic Documents of the Borrower or any Subsidiary, or any Governmental Rule or any material agreement or instrument to which the Borrower or any Subsidiary is a party or by which it is bound or to which it or its Properties are subject, or constitute a default under any such agreement or instrument, or result in the creation or imposition of any Lien upon any of the revenues or assets of the Borrower or any Subsidiary pursuant to the terms of any such agreement or instrument other than the Liens created by the Combined Loan Documents.

SECTION 3.5 Authority. Each Loan Party has all necessary power and authority to execute, deliver and perform its obligations under the Combined Loan Documents to which it is a party; and the execution, delivery and performance by each Loan Party of the Combined Loan Documents to which it is a party, have been duly authorized by all necessary action on its part; and the Combined Loan Documents constitute the legal, valid and binding obligations of each

Loan Party thereto, enforceable in accordance with their terms, except to the extent that enforcement may be subject to any applicable bankruptcy, insolvency or similar laws generally affecting the enforcement of creditors’ rights.

SECTION 3.6 Approvals. Except for filings necessary to perfect Liens created under the Combined Loan Documents, no authorizations, approvals or consents of, and no filings or registrations with, any Governmental Authority are necessary for the execution, delivery or performance by any Loan Party of the Combined Loan Documents or for the validity or enforceability thereof.

SECTION 3.7 Use of Proceeds and Letters of Credit. The Borrower will, and will cause each Subsidiary to, use the proceeds of the Loans (a) to refinance existing Indebtedness of the Borrower and its Subsidiaries, (b) to reimburse each Issuing Bank for LC Disbursements in accordance with Section 2.4(e), (c) to pay a portion of the purchase price for the Acquisition, or (d) for the Borrower’s and its Subsidiaries’ general corporate purposes, including intercompany Investments. No part of the proceeds of any Loan will be used, whether directly or indirectly, for any purpose that entails a violation of any of the regulations of the Board, including Regulation U. Letters of Credit will be issued only to support normal and customary oil and gas operations undertaken by the Borrower or any of its Subsidiaries in the ordinary course of its business.

SECTION 3.8 ERISA. Except as could not reasonably be expected to have a Material Adverse Effect (or with respect to clauses (a), (b) or (e) where the failure to take such actions could not reasonably be expected to have a Material Adverse Effect):

(a) The Borrower, each Subsidiary and each ERISA Affiliate have complied with ERISA and, where applicable, the Code regarding each Plan.

(b) Each Plan is, and has been, maintained in substantial compliance with ERISA and, where applicable, the Code.

(c) No act, omission or transaction has occurred which could result in imposition on the Borrower, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to section 502(c), (i) or (l) of ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary duty liability damages under section 409 of ERISA.

(d) No Plan (other than a defined contribution plan) or any trust created under any such Plan has been terminated within the last six (6) calendar years.

No ERISA Event with respect to any Plan has occurred.

(e) Full payment when due has been made of all amounts which the Borrower, any Subsidiary or any ERISA Affiliate is required under the terms of each Plan or applicable law to have paid as contributions to such Plan, and no accumulated funding deficiency (as defined in

section 302 of ERISA and section 412 of the Code), whether or not waived, exists with respect to any Plan.

(f) The actuarial present value of the benefit liabilities under each Plan which is subject to Title IV of ERISA does not, as of the end of the Borrower’s most recently ended fiscal year, exceed the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities. The term “actuarial present value of the benefit liabilities” shall have the meaning specified in section 4041 of ERISA.

(g) None of the Borrower, any Subsidiary or any ERISA Affiliate sponsors, maintains, or contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including, without limitation, any such plan maintained to provide benefits to former employees of such entities, that may not be terminated by the Borrower, a Subsidiary or any ERISA Affiliate in its sole discretion at any time without any material liability.

(i) None of the Borrower, any Subsidiary or any ERISA Affiliate is required to provide security under section 401(a)(29) of the Code due to a Plan amendment that results in an increase in current liability for the Plan.

SECTION 3.9 Taxes. Each of the Borrower and its Subsidiaries has filed all U.S. Federal income tax returns, Canadian income tax returns and all other tax returns which are required to be filed by them and have paid all material taxes due pursuant to such returns or pursuant to any assessment received by the Borrower or any Subsidiary. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of taxes and other governmental charges are, in the opinion of the Borrower, adequate. No tax lien has been filed and, to the knowledge of the Borrower, no claim is being asserted with respect to any such tax, fee or other charge.

SECTION 3.10 Properties, etc.

(a) Each of the Borrower and each of its Subsidiaries has good and defensible title to (i) those Mortgaged Properties, if any, used in calculating compliance with the collateral coverage requirements set forth in Section 5.13 and (ii) its and their other material (individually or in the aggregate) Properties, in each case free and clear of all Liens, except Liens permitted by Section 7.2. Except as set forth in Schedule 3.10, after giving full effect to the Excepted Liens, the Borrower or its Subsidiaries owns the net interests in production attributable to the Hydrocarbon Interests reflected in the most recently delivered Reserve Report and the ownership of such Properties shall not in any material respect obligate the Borrower or any Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the most recently delivered Reserve Report. All information contained in the most recently delivered Reserve Report is true and correct in all material respects as of the date thereof.

(b) All leases and agreements necessary for the conduct of the business of the Borrower and its Subsidiaries are valid and subsisting, in full force and effect and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which would affect in any material respect the conduct of the business of the Borrower and its Subsidiaries.

(c) The rights, Properties and other assets presently owned, leased or licensed by the Borrower and its Subsidiaries including, without limitation, all easements and rights of way, include all rights, Properties and other assets necessary to permit the Borrower and its Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the Global Effective Date.

SECTION 3.11 No Material Misstatements. No written information, statement, exhibit, certificate, document or report furnished to the Global Administrative Agent, the other Agents and the Lenders (or any of them) by the Borrower or any Subsidiary in connection with the negotiation of the Combined Loan Documents contained any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statement contained therein not materially misleading in the light of the circumstances in which made and with respect to the Borrower and its Subsidiaries taken as a whole. There is no fact existing with respect to the Borrower or any Subsidiary which could reasonably be expected to have a Material Adverse Effect or in the future could reasonably be likely to have (so far as the Borrower can now foresee) a Material Adverse Effect and which has not been set forth in this Agreement or the other documents, certificates and statements furnished to the Global Administrative Agent by or on behalf of the Borrower or any Subsidiary prior to, or on, the Global Effective Date in connection with the transactions contemplated hereby.

(b) Except as provided in Section 5.11, the Borrower will not, and will not permit any of its Subsidiaries, to enter into a Hedging Agreement (i) which creates any Lien other than pursuant to any Combined Loan Document or as permitted by Section 7.2(h) or (ii) with a counterparty with a rating of its senior, unsecured, long-term indebtedness for borrowed money that is not guaranteed by any other Person or subject to any other credit enhancement of lower than “BBB-” or Baa3” by S&P and ▇▇▇▇▇’▇, respectively.

ARTICLE IX

Agents

Each of the Lenders, the Issuing Banks and the other Agents hereby irrevocably appoints JPMorgan Chase Bank as the Global Administrative Agent, BNP Paribas, Wachovia Bank, National Association and The Bank of Nova Scotia, as Global Syndication Agents, and U.S. Bank National Association, as U.S. Documentation Agent, and authorizes each such Agent to take such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto.

Any bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

The Agents shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Agents shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) each Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that such Agent is required to exercise following its receipt of written instructions from the Majority Lenders (or such other number or percentage of the Combined Lenders as shall be necessary under the circumstances as provided in Section 10.2), and (c) except as expressly set forth in the Loan Documents, the Agents shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as such Agent or any of its Related Parties in any capacity. Each Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders (or such other number or percentage of the Combined Lenders as shall be necessary under the circumstances as provided in Section 10.2) or in the absence of its own gross negligence or willful misconduct; PROVIDED, HOWEVER, THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH OF THE AGENTS BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. Each Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to such Agent by the Borrower or a Lender, and such Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to such Agent.

The Global Administrative Agent and the other Agents shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Global Administrative Agent and the other Agents also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Global Administrative Agent and the other Agents may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Any Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by such Agent. Any Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of such Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as an Agent.

Subject to the appointment and acceptance of a successor Global Administrative Agent as provided in this paragraph, the Global Administrative Agent may resign at any time by notifying the Combined Lenders and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Global Administrative Agent gives notice of its resignation, then the retiring Global Administrative Agent may, on behalf of the Combined Lenders and the Issuing Banks, appoint a successor Global Administrative Agent which shall be a bank with an office in New York City, or an Affiliate of any such bank. Upon the acceptance of its appointment as Global Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Global Administrative Agent, and the retiring Global Administrative Agent shall be discharged from its duties and obligations hereunder (other than its obligations under Section 10.12). The fees payable by the Borrower to a successor Global Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Global Administrative Agent’s resignation hereunder, the provisions of this Article and Section 10.3 shall continue in effect for the benefit of such retiring Global Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Global Administrative Agent.

Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement, the Intercreditor Agreement, and, when applicable, the Senior Debt Intercreditor Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based

upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Each of the Lenders, for itself and on behalf of any of its Affiliates, and the Issuing Banks hereby irrevocably appoints the Global Administrative Agent to act as its agent under the Intercreditor Agreement and the Senior Debt Intercreditor Agreement and authorizes the Global Administrative Agent to execute the Intercreditor Agreement and the Senior Debt Intercreditor Agreement on its behalf and to take such actions on its behalf and to exercise such powers as are delegated to the Global Administrative Agent by the terms hereof and thereof, together with such actions and powers as are reasonably incidental thereto.

(c) Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this Agreement shall be deemed to have been given on the date of receipt.

SECTION 10.2 Waivers; Amendments.

(a) No failure or delay by the Global Administrative Agent, any Issuing Bank or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Global Administrative Agent, the Issuing Banks and the Lenders hereunder and under the

other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Global Administrative Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any of the Combined Loan Documents nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Global Administrative Agent with the consent of the Majority Lenders, or, in the case of any other Combined Loan Document, pursuant to an agreement or agreements in writing entered into by the relevant Loan Parties thereto and the Majority Lenders or by the relevant Loan Parties thereto and the Global Administrative Agent with the consent of the Majority Lenders, provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section 10.2, or Sections 2.7 or 2.10, or the definition of “Combined Lenders,” “Combined Revolving Lenders,” “Required Lenders,” “Majority Lenders” or “Super Majority Lenders” or any other provision of any Combined Loan Document specifying the number or percentage of Lenders, Canadian Revolving Lenders, Canadian Term Lenders, Combined Lenders or Combined Revolving Lenders required to determine or redetermine the Global Borrowing Base or the Revolving Borrowing Base or required to waive, amend or modify any rights thereunder or make any determination or grant any consent thereunder, without the written consent of each Combined Lender, (vi) release any Loan Party from its Guaranty (except as expressly provided in such Guaranty), or limit its liability in respect of such Guaranty, without the written consent of each Combined Lender, or (vii) except as expressly provided herein, in the Intercreditor Agreement, the Senior Debt Intercreditor Agreement or in the Security Documents (as defined herein and in each other Combined Credit Agreement), release all or any part of the Collateral from the Liens of the Security Documents (as defined herein and in each other Combined Credit Agreement), without the written consent of each Combined Lender; provided further that no such agreement shall amend, waive, modify or otherwise affect the rights or duties of any Agent (as defined herein and in each other Combined Credit Agreement) or any Issuing Bank (as defined herein and in each other Combined Credit Agreement) without the prior written consent of such Agent (as defined herein and in each other Combined Credit Agreement) or any Issuing Bank (as defined herein and in each other Combined Credit Agreement), as the case may be; provided further that the Global Administrative Agent shall have the right to execute and deliver any release of Lien (or other similar instrument) without the consent of any Lender to the extent such

release is required to permit the Borrower or a Subsidiary to consummate a transaction permitted by this Agreement or the other Combined Loan Documents.

SECTION 10.3 Expenses; Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all legal, printing, recording, syndication, travel, advertising and other reasonable out-of-pocket expenses incurred by the Agents, the Arranger and their Affiliates, including the reasonable fees, charges and disbursements of counsel for the Agents and the Arranger, in connection with the syndication of the credit facilities provided for herein, the preparation, execution, delivery and administration of this Agreement, the Loan Documents and each other document or instrument relevant to this Agreement or the Loan Documents and any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by an Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, (iii) the filing, recording, refiling or rerecording of the Pledge Agreements and any other Security Documents and/or any Uniform Commercial Code financing statements relating thereto and all amendments, supplements and modifications to, and all releases and terminations of, any thereof and any and all other documents or instruments of further assurance required to be filed or recorded or refiled or rerecorded by the terms hereof or of the Pledge Agreements and any other Security Documents, and (iv) all reasonable out-of-pocket expenses incurred by the Agents, any Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Agents, any Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such reasonable out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) The Borrower shall indemnify the Agents, each Issuing Bank, the Arranger and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable out-of-pocket fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any other agreement or instrument contemplated hereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the Financing Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by an Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property currently or formerly owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity and release shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related

expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee (IT BEING UNDERSTOOD THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH OF THE INDEMNITEES BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL).

(c) To the extent that the Borrower fails to pay any amount required to be paid by the Borrower to the Global Administrative Agent or an Issuing Bank under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Global Administrative Agent or such Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Global Administrative Agent or such Issuing Bank in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Financing Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable not later than thirty (30) days after written demand therefor.

SECTION 10.4 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Bank that issues any Letter of Credit), except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Global Administrative Agent, each Issuing Bank and each Combined Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Bank that issues any Letter of Credit) and, to the extent expressly contemplated hereby, the Related Parties of each of the Global Administrative Agent, the Issuing Banks and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that (i) except in the case of an assignment to a Lender, a Lender Affiliate or an Approved Fund, each of the Borrower and the Global Administrative Agent (and, in the case of an assignment of all or a portion of a Commitment or any Lender’s obligations in

respect of its LC Exposure, the Issuing Banks) must give their prior written consent to such assignment (which consents shall not be unreasonably withheld), (ii) except in the case of an assignment to a Lender, a Lender Affiliate or an Approved Fund, or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Global Administrative Agent) shall be in increments of U.S.$1,000,000 and not less than U.S.$10,000,000 unless each of the Borrower and the Global Administrative Agent otherwise consent, (iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, except that this clause (iii) shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of its Commitments or Loans in conformity with the Intercreditor Agreement and the Senior Debt Intercreditor Agreement, (iv) the parties to each assignment shall execute and deliver to the Global Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of U.S.$3,500, (v) the assignee, if it shall not be a Lender, shall deliver to the Global Administrative Agent an Administrative Questionnaire, and (vi) after giving effect to any assignment hereunder, the assigning Lender shall have a Commitment of at least U.S.$10,000,000 unless each of the Borrower and the Global Administrative Agent otherwise consents; and provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default under Section 8.1 has occurred and is continuing. Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance, 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 Acceptance, 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 Acceptance, be released from its obligations under this Agreement and the other Loan Documents (and, in the case of an Assignment and Acceptance 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 2.15, 2.16, 2.17, 2.18, 2.20 and 10.3 and 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 the Borrower, shall maintain at one of its offices in New York City a copy of each Assignment and Acceptance 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 the 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 the Borrower, any Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Global Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register and will provide prompt written notice to the 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 the 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); 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 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; provided that 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 to Section 10.2(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to 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 of Section 10.8 and 10.12 as 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 under Section 2.15, 2.16 or 2.17 than 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 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 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; provided that 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 10.5 Survival. 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, 2.20, 10.3 and 10.12 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 10.6 Counterparts; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Except as provided in Section 4.1, this Agreement shall become effective when it shall have been executed by the Global Administrative Agent and when the Global 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 manually executed counterpart of this Agreement.

SECTION 10.7 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any 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 10.8 Right 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 the Borrower or any of its Subsidiaries (other than a Foreign Subsidiary) against any and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured; provided, however, that any such set-off and application shall be subject to the provisions of Section 2.18. As security for such obligations, the Borrower hereby grants to the Agents, each Issuing Bank and each Lender a continuing security interest in any and all balances, credits, deposits, accounts or moneys of the Borrower and its Subsidiaries (other than a Foreign Subsidiary) then or thereafter maintained

with any of the Agents, such Issuing Bank and such Lenders. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 10.11 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 10.12 Confidentiality. In the event that the Borrower provides to the Global Administrative Agent or the Lenders confidential information belonging to the Borrower or any of its Subsidiaries, then the Global Administrative Agent and the Lenders shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without the Global Administrative Agent or the Lenders breaching their obligation of confidence to the Borrower, (iii) are previously known by the Global Administrative Agent or the Lenders from some source other than the Borrower, (iv) are hereafter developed by the Global Administrative Agent or the Lenders without using the Borrower’s information, (v) are hereafter obtained by or available to the Global Administrative Agent or the Lenders from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (vi) are disclosed with the Borrower’s consent, (vii) must be disclosed either pursuant to any Governmental Rule or to Persons regulating the activities of the Global Administrative Agent or the Lenders, or (viii) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, the Global Administrative Agent or a Lender may disclose any such information to any other Lender, any independent petroleum engineers or consultants, any independent certified public or chartered accountants, any legal counsel employed by such Person in connection with this Agreement or any other Combined Loan Document, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans; provided, however, that the Global Administrative Agent or the Lenders shall receive a confidentiality agreement from the

Person to whom such information is disclosed such that said Person shall have the same obligation to maintain the confidentiality of such information as is imposed upon the Global Administrative Agent or the Lenders hereunder. Furthermore, this obligation of confidence shall not apply to, and each of the Agents and the Lenders (and each Person employed or retained by such Agents or Lenders who are or are expected to become engaged in evaluating, approving, structuring or administering the Loans) may disclose to any Person, without limitation of any kind, the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the Loan transactions contemplated by this Agreement and the other Combined Loan Documents, and all materials of any kind (including opinions or other tax analyses) related thereto that are or have been provided to such Agent or Lender relating to such tax treatment or tax structure; provided that with respect to any document or similar item that in either case contains confidential information concerning such tax treatment or tax structure of the Loan transactions contemplated by this Agreement and the other the Combined Loan Documents as well as other information, this sentence shall only apply to such portions of the documents or similar item that relate to such tax treatment or tax structure. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three (3) years from the date the information was furnished, unless the Borrower requests in writing at least thirty (30) days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period. The Borrower waives any and all other rights it may have to confidentiality as against the Global Administrative Agent and the Lenders arising by contract, agreement, statute or law except as expressly stated in this Section 10.12.

SECTION 10.13 Interest Rate Limitation. It is the intention of the parties hereto to conform strictly to applicable interest, usury and criminal laws and, anything herein to the contrary notwithstanding, the obligations of the Borrower and the Guarantors to a Lender, any Issuing Bank or any Agent under this Agreement or any Combined Loan Document shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable 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 applicable to such Lender or Agent notwithstanding anything to the contrary in this Agreement or any other Combined Loan Document then, in that event, notwithstanding anything to the contrary in this Agreement or any other Combined Loan Document, it is agreed as follows:

(i) the provisions of this Section shall govern and control;

(ii) 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 Combined Loan Document or otherwise in connection with this Agreement or any Combined Loan Document by such Lender, such Issuing Bank or such Agent shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to each Lender, each Issuing Bank and the Agents herein called the “Highest Lawful Rate”), and any excess shall be cancelled automatically and if theretofore paid shall be credited to the

Borrower by such Lender, such Issuing Bank or such Agent (or, if such consideration shall have been paid in full, such excess refunded to the Borrower);

(iii) all sums paid, or agreed to be paid, to such Lender, such Issuing Bank or such Agent for the use, forbearance and detention of the indebtedness of the Borrower to such Lender, such Issuing Bank or such Agent hereunder or under any Combined 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;

(iv) if at any time the interest provided pursuant to this Section or any other clause of this Agreement or any other Combined Loan Document, together with any other fees or compensation payable pursuant to this Agreement or any other Combined 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 Combined Loan Document shall be limited, notwithstanding anything to the contrary in this Agreement or any other Combined 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 Combined Loan Document below the Highest Lawful Rate until the total amount of interest accrued pursuant to this Agreement or such other Combined 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 rate per annum equal 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, plus the amount of fees which would have been received but for the effect of this Section; and

(v) 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 Combined Loan Documents) by such Lender, such Issuing Bank or such Agent would cause such Lender to charge the 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 the Borrower so that the rate of interest paid by the Borrower shall not exceed a criminal rate of interest from the date this Agreement was entered into.

SECTION 10.14 Collateral Matters; Hedging Agreements; Overdraft Facility. The benefit of the Security Documents and of the provisions of this Agreement relating to the Collateral shall also extend to and be available to (i) those Lenders or their Affiliates that are counterparties to the Hedging Agreements on a pro rata basis in respect of any Hedging Obligations of the Borrower or any of its Subsidiaries that are in effect at such time as such

Person (or its Affiliate) is a Lender, but only while such Person or its Affiliate is a Lender and (ii) those Lenders which are parties to the Overdraft Facility on a pro rata basis in respect of any Obligations of the Borrower or any of its Subsidiaries under such Overdraft Facility up to a maximum of $5,000,000 that are in effect at such time as such Person is a Lender, but only while such Person is a Lender. It is the intention of the parties hereto that the Hedging Obligations of the Borrower and its Subsidiaries under any Hedging Agreement with a Combined Lender, or any Affiliate of a Combined Lender, will rank pari passu with the obligations of such Person under the Combined Loan Documents, including the Obligations, to the extent applicable.

SECTION 10.15 Arranger; U.S. Documentation Agent; Global Syndication Agents; Other Agents. None of the Persons identified on the facing page or the signature pages of this Agreement as the “Sole Lead Arranger and Bookrunner” or “U.S. Documentation Agent” or “Global Syndication Agents” or any other Agent (other than the Global Administrative Agent) shall have any right, power, obligation, liability, responsibility or duty under this Agreement or any other Combined Loan Document other than, except in the case of the Arranger, those applicable to all Lenders as such. Without limiting the foregoing, none of the Arranger, the U.S. Documentation Agent, the Global Syndication Agents or any other Agent (other than the Global Administrative Agent) shall have or be deemed to have any fiduciary relationship with any Lender or the Borrower or any of its Subsidiaries. The Borrower and each Lender acknowledges that it has not relied, and will not rely, on any of the Arranger, the U.S. Documentation Agent, the Global Syndication Agents or any other Agent (other than the Global Administrative Agent) in deciding to enter into this Agreement or in taking or not taking any action hereunder or under the Combined Loan Documents.

SECTION 10.16 Intercreditor Agreement; Senior Debt Intercreditor Agreement; Security Documents. For so long as the Intercreditor Agreement shall be in effect, the terms and conditions of this Agreement and the other Loan Documents are subject to the terms of the Intercreditor Agreement. In the event of any inconsistency between this Agreement or any other Loan Document and the terms of the Intercreditor Agreement, the Intercreditor Agreement shall control. For so long as any Senior Debt Intercreditor Agreement shall be in effect, the terms and conditions of this Agreement and the other Loan Documents are subject to the terms of such Senior Debt Intercreditor Agreement. In the event of any inconsistency between this Agreement or any other Loan Document and the terms of any Senior Debt Intercreditor Agreement, the Senior Debt Intercreditor Agreement shall control. In the event of any inconsistency between this Agreement and the terms of any other Loan Document, this Agreement shall control.

SECTION 10.17 NO ORAL AGREEMENTS. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

WHEREAS, pursuant to a Credit Agreement, dated as of June 27, 2003 (together with all amendments, supplements, restatements and other modifications, if any, including, without limitation, any written consents and waivers, from time to time thereafter made thereto, the “Credit Agreement”), among ▇▇▇ ▇▇▇▇▇, Inc., a Delaware corporation (the “Borrower”), the various financial institutions as are, or may from time to time become, parties to the Credit Agreement (the “Lenders”), the various financial institutions as are or may from time to time become Agents under the Credit Agreement and the Global Administrative Agent, the Lenders have agreed to extend Commitments to make Loans to the Borrower, and the Issuing Banks have agreed to issue Letters of Credit for the account of the Borrower and its respective Subsidiaries; and

WHEREAS, the Guarantors have duly authorized the execution, delivery and performance of this Guaranty; and

WHEREAS, it is in the best interests of the Guarantors to execute this Guaranty inasmuch as the Guarantors will derive substantial direct and indirect benefits from the Loans made to, and the Letters of Credit issued from time to time for the account of, the Borrower and its Subsidiaries by the Lenders and the Issuing Banks, as the case may be, pursuant to the Credit Agreement and the financial accommodations extended from time to time to the Borrower and its Subsidiaries by the Lender Parties pursuant to the Hedging Agreements;

The Guaranty

Section 2.1 Obligations Guaranteed. Each Guarantor hereby irrevocably, unconditionally and jointly and severally guarantees in favor of the Global Administrative Agent for the benefit of the Lender Parties the prompt payment of the Obligations when due, whether at maturity or otherwise; provided, however, that, notwithstanding anything herein or in any other Loan Document to the contrary, the maximum liability of each Guarantor hereunder shall in no event exceed the Maximum Guaranteed Amount.

Section 2.2 Nature of Guaranty. This Guaranty is an absolute, irrevocable, completed and continuing guaranty of payment and not a guaranty of collection, and no notice of the Obligations or any extension of credit already or hereafter contracted by or extended to Borrower

need be given to any Guarantor. This Guaranty may not be revoked by any Guarantor and shall continue to be effective with respect to the Obligations arising or created after any attempted revocation by any Guarantor and shall remain in full force and effect until the Obligations are paid in full and the Commitments of the Lenders are terminated notwithstanding that from time to time prior thereto no Obligations may be outstanding. The Borrower and the Lender Parties may modify, alter, rearrange, extend for any period and/or renew from time to time the Obligations, and the Lenders may waive any Default or Events of Default without notice to any Guarantor and in such event each Guarantor will remain fully bound hereunder on the Obligations. This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of the Obligations is rescinded or must otherwise be returned by any of the Lender Parties upon the insolvency, bankruptcy or reorganization of Borrower or otherwise, all as though such payment had not been made. This Guaranty may be enforced by the Global Administrative Agent and any subsequent holder of any of the Obligations and shall not be discharged by the assignment or negotiation of all or part of the Obligations. Each Guarantor hereby expressly waives presentment, demand, notice of non-payment, protest and notice of protest and dishonor, notice of Default or Event of Default, notice of intent to accelerate the maturity and notice of acceleration of the maturity and any other notice in connection with the Obligations other than the notice required by the second sentence of Section 2.5 hereof, and also notice of acceptance of this Guaranty, acceptance on the part of the Lender Parties being conclusively presumed by the request of the Lender Parties for this Guaranty and delivery of the same to the Global Administrative Agent.

Section 2.3 Global Administrative Agent’s Rights. Each Guarantor authorizes the Global Administrative Agent, without notice or demand and without affecting any Guarantor’s liability hereunder, to take and hold security for the payment of this Guaranty and/or the Obligations, and exchange, enforce, waive and release any such security; and to apply such security and direct the order or manner of sale thereof as the Global Administrative Agent in its discretion may determine; and to obtain a guaranty of the Obligations from any one or more Persons and at any time or times to enforce, waive, rearrange, modify, limit or release any of such other Persons from their obligations under such guaranties.

Section 2.4 Guarantor’s Waivers.

(a) General. Each Guarantor waives any right to require any of the Lender Parties to (i) proceed against Borrower or any other Person liable on the Obligations, (ii) enforce any of their rights against any other guarantor of the Obligations, (iii) proceed or enforce any of their rights against or exhaust any security given to secure the Obligations, (iv) have Borrower joined with any Guarantor in any suit arising out of this Guaranty and/or the Obligations, or (v) pursue any other remedy in the Lender Parties’ powers, at law or in equity, whatsoever. The Lender Parties shall not be required to mitigate damages or take any action to reduce, collect or enforce the Obligations. Each Guarantor waives any defense arising by reason of any disability, lack of corporate authority or power, or other defense of Borrower or any other guarantor of the Obligations, and shall remain liable hereon regardless of whether Borrower or any other guarantor be found not liable thereon for any reason. Whether and when to exercise any of the remedies of the Lender Parties under any of the Loan Documents shall be in the sole and absolute discretion of the Global Administrative Agent, and no delay by the Global Administrative Agent in enforcing any remedy, including delay in conducting a foreclosure sale,

shall be a defense to any Guarantor’s liability under this Guaranty. To the extent allowed by applicable law, each Guarantor hereby waives any good faith duty on the part of the Global Administrative Agent in exercising any remedies provided in the Loan Documents.

(b) Subrogation. Until the Obligations have been paid in full and the Commitments of the Lender Parties are terminated, each Guarantor waives all rights of subrogation or reimbursement against the Borrower, whether arising by contract or operation of law (including, without limitation, any such right arising under any federal or state bankruptcy or insolvency laws) and waives any right to enforce any remedy which the Guarantors now have or may hereafter have against the Borrower, and waives any benefit or any right to participate in any security now or hereafter held by the Global Administrative Agent or any Lender Party.

Section 2.5 Maturity of Obligations; Payment. Each Guarantor agrees that if the maturity of any of the Obligations is accelerated by bankruptcy or otherwise, such maturity shall also be deemed accelerated for the purpose of this Guaranty without demand or notice to any Guarantor. Each Guarantor will, forthwith upon notice from the Global Administrative Agent, pay to the Global Administrative Agent the amount due and unpaid of the Obligations by Borrower and Guaranteed hereby up to such Guarantor’s Maximum Guaranteed Amount. The failure of the Global Administrative Agent to give this notice shall not in any way release or reduce the liability of any Guarantor hereunder.

Section 2.6 Global Administrative Agent’s Expenses. If any Guarantor fails to pay the Obligations after notice from the Global Administrative Agent of Borrower’s failure to pay any Obligations when due, and if the Global Administrative Agent or any of the Lender Parties: obtain the services of attorneys for collection of amounts owing by any Guarantor hereunder; obtain advice of counsel in respect of any of their rights under this Guaranty; file suit to enforce this Guaranty or participate in proceedings in any bankruptcy, probate, receivership or other judicial proceeding for the establishment or collection of any amount owing by any Guarantor hereunder; or if any amount owing by any Guarantor hereunder is collected through any such proceedings, each Guarantor agrees to pay to the Global Administrative Agent the Global Administrative Agent’s reasonable attorneys’ fees in connection with each of the foregoing events.

Section 2.7 Liability. It is expressly agreed that the liability of each Guarantor for the payment of the Obligations guaranteed hereby shall be primary and not secondary.

Section 2.8 Events and Circumstances Not Reducing or Discharging Guarantors’ Obligations. To the fullest extent permitted by law, each Guarantor hereby consents and agrees to each of the following, agrees that no Guarantor’s obligations under this Guaranty shall be released, diminished, impaired, reduced or adversely affected by any of the following and waives any rights (including without limitation rights to notice) which such Guarantor might otherwise have as a result of or in connection with any of the following:

(a) Modifications, etc. Any renewal, extension, modification, increase, decrease, alteration or rearrangement of all or any part of the Obligations, the Credit Agreement, the Loan Documents or any instrument executed in connection therewith, or any contract or

understanding between Borrower and any of the Lender Parties, or any other Person, pertaining to the Obligations.

(d) Invalidity of Obligations. The invalidity, illegality or unenforceability of all or any part of the Obligations, or any document or agreement executed in connection with the Obligations, for any reason whatsoever, including without limitation the fact that the Obligations, or any part thereof, exceed the amount permitted by law, the act of creating the Obligations or any part thereof is ultra ▇▇▇▇▇, the officers or representatives executing the documents or otherwise creating the Obligations acted in excess of their authority, the Obligations violate applicable usury laws, the Borrower has valid defenses, claims or offsets (whether at law, in equity or by agreement) which render the Obligations wholly or partially uncollectible from Borrower, the creation, performance or repayment of the Obligations (or the execution, delivery and performance of any document or instrument representing part of the Obligations or executed in connection with the Obligations, or given to secure the repayment of the Obligations) is illegal, uncollectible, legally impossible or unenforceable, or the Credit Agreement or other documents or instruments pertaining to the Obligations have been forged or otherwise are irregular or not genuine or authentic.

(e) Release of Obligors. Any full or partial release of the liability of Borrower on the Obligations or any part thereof, of any other Guarantor, or any other Person now or hereafter liable, whether directly or indirectly, jointly, severally, or jointly and severally, to pay, perform, Guarantee or assure the payment of the Obligations or any part thereof, it being recognized, acknowledged and agreed by each Guarantor that, subject to the terms of Section 2.1 and Section 2.9, each Guarantor may be required to pay the Obligations in full without assistance or support of any other Person, and that such Guarantor has not been induced to enter into this Guaranty on the basis of a contemplation, belief, understanding or agreement that any party other than the Borrower will be liable to perform the Obligations, or that the Lender Parties will look to any other party to perform the Obligations.

(f) Other Security. The taking or accepting of any other security, Collateral or guaranty, or other assurance of payment, for all or any part of the Obligations.

(g) Release of Collateral, etc. Any release, surrender, exchange, subordination, deterioration, waste, loss or impairment (including without limitation negligent, willful, unreasonable or unjustifiable impairment) of any Collateral, Property or security, at any

(i) Status of Liens. The fact that any Collateral, security or Lien contemplated or intended to be given, created or granted as security for the repayment of the Obligations shall not be properly perfected or created, or shall prove to be unenforceable or subordinate to any other Lien, it being recognized and agreed by each Guarantor that such Guarantor is not entering into this Guaranty in reliance on, or in contemplation of the benefits of, the validity, enforceability, collectibility or value of any of the Collateral for the Obligations;

(j) Payments Rescinded. Any payment by Borrower to the Lender Parties is held to constitute a preference under the bankruptcy laws, or for any reason the Lender Parties are required to refund such payment or pay such amount to Borrower or any other Person; or

(k) Other Actions Taken or Omitted. Any other action taken or omitted to be taken with respect to the Credit Agreement, the Obligations, or the security and Collateral therefor, whether or not such action or omission prejudices any Guarantor or increases the likelihood that any Guarantor will be required to pay the Obligations pursuant to the terms hereof; it being the unambiguous and unequivocal intention of each Guarantor that such Guarantor shall be obligated to pay the Obligations when due, notwithstanding any occurrence, circumstance, event, action, or omission whatsoever, whether contemplated or uncontemplated, and whether or not otherwise or particularly described herein, except for the full and final payment and satisfaction of the Obligations.

Section 2.9 Right of Subrogation and Contribution. If any Guarantor makes a payment in respect of the Obligations, it shall be subrogated to the rights of the Lender Parties against the Borrower with respect to such payment and shall have the rights of contribution against the other Guarantors as set forth in this Section 2.9; provided that such Guarantor shall not enforce its rights to any payment by way of subrogation or by exercising its rights of contribution or reimbursement or the right to participate in any security or Collateral now or hereafter held by or for the benefit of the Lender Parties until the Obligations have been unconditionally and irrevocably paid in full and are not subject to disgorgement in bankruptcy or otherwise. Each Guarantor agrees that if after all the Obligations have been paid in full its then current Net Payments are less than the amount of its then current Contribution Obligation, such Guarantor shall pay to the other Guarantors an amount (together with any payments required of the other Guarantors by this Section 2.9) such that the Net Payments made by all Guarantors in respect of the Obligations shall be shared among all of the Guarantors in proportion to their respective Contribution Percentage.

(e) No Legal Bar or Resultant Lien.

(f) No Consent. Such Guarantor’s execution, delivery and performance of this Guaranty does not require the consent or approval of any other Person, including without limitation any Governmental Authority of the United States or any state thereof or any political subdivision of the United States or any state thereof.

(g) Solvency.

Each Guarantor hereby acknowledges that it has been furnished a copy of the Credit Agreement and that it is thoroughly familiar with the representations, warranties and covenants which are incorporated herein by virtue of this Section 3.3.

ARTICLE 4

Subordination of Indebtedness

Section 4.1 Subordination of All Guarantor Claims. As used herein, the term “Guarantor Claims” means all debts and liabilities of Borrower to any Guarantor, whether such debts and liabilities now exist or are hereafter incurred or arise, or whether the obligation of Borrower thereon be direct, contingent, primary, secondary, several, joint and several, or otherwise, and irrespective of whether such debts or liabilities be evidenced by note, contract, open account, or otherwise, and irrespective of the Person or Persons in whose favor such debts or liabilities may, at their inception, have been, or may hereafter be created, or the manner in which they have been or may hereafter be acquired by any Guarantor. The Guarantor Claims shall include without limitation all rights and claims of any Guarantor against Borrower arising as a result of subrogation or otherwise as a result of such Guarantor’s payment of all or a portion of the Obligations. If an Event of Default has occurred and is continuing, then no Guarantor shall receive or collect, directly or indirectly, from Borrower or any other party any amount upon the Guarantor Claims.

Section 4.2 Claims in Bankruptcy. In the event of receivership, bankruptcy, reorganization, arrangement, debtor’s relief, or other insolvency proceedings involving Borrower as debtor, the Lender Parties shall have the right to prove their claim in any proceeding, so as to establish their rights hereunder and receive directly from the receiver, trustee or other court custodian, dividends and payments which would otherwise be payable upon Guarantor Claims. Each Guarantor hereby assigns such dividends and payments to the Lender Parties. Should the Global Administrative Agent or any Lender receive, for application upon the Obligations, any such dividend or payment which is otherwise payable to any Guarantor, and which, as between Borrower and such Guarantor, shall constitute a credit upon the Guarantor Claims, then upon payment in full of the Obligations, such Guarantor shall become subrogated to the rights of the Lender Parties to the extent that such payments to the Lender Parties on the Guarantor Claims have contributed toward the liquidation of the Obligations, and such subrogation shall be with respect to that proportion of the Obligations which would have been unpaid if the Global Administrative Agent or a Lender had not received dividends or payments upon the Guarantor Claims.

Section 4.3 Payments Held in Trust. In the event that, notwithstanding Sections 4.1 and 4.2 above, any Guarantor should receive any funds, payments, claims or distributions which are prohibited by such Sections, such Guarantor agrees to hold in trust for the Lender Parties an

amount equal to the amount of all funds, payments, claims or distributions so received, and agrees that it shall have absolutely no dominion over such funds, payments, claims or distributions except to pay them promptly to the Global Administrative Agent, and each Guarantor covenants promptly to pay the same to the Global Administrative Agent.

Section 4.4 Liens Subordinate. Each Guarantor agrees that any Liens, security interests, judgment liens, charges or other encumbrances upon Borrower’s assets securing payment of the Guarantor Claims shall be and remain inferior and subordinate to any Liens, security interests, judgment liens, charges or other encumbrances upon Borrower’s assets securing payment of the Obligations, regardless of whether such encumbrances in favor of such Guarantor, the Global Administrative Agent or the Lender Parties presently exist or are hereafter created or attach. Without the prior written consent of the Required Lenders, no Guarantor shall (a) exercise or enforce any creditor’s right it may have against the Borrower, or (b) foreclose, repossess, sequester or otherwise take steps or institute any action or proceeding (judicial or otherwise, including without limitation the commencement of or joinder in any liquidation, bankruptcy, rearrangement, debtor’s relief or insolvency proceeding) to enforce any Lien, mortgages, deeds of trust, security interest, collateral rights, judgments or other encumbrances on assets of Borrower held by any Guarantor.

Section 4.5 Notation of Records. All promissory notes, accounts receivable ledgers or other evidence of the Guarantor Claims accepted by or held by any Guarantor shall contain a specific written notice thereon that the indebtedness evidenced thereby is subordinated to the Obligations pursuant to the terms of this Guaranty.

ARTICLE 5

Miscellaneous

Section 5.1 Successors and Assigns. This Guaranty is and shall be in every particular available to the successors and assigns of the Lender Parties and is and shall always be fully binding upon the legal representatives, successors and assigns of each Guarantor, notwithstanding that some or all of the monies, the repayment of which this Guaranty applies, may be actually advanced after any bankruptcy, receivership, reorganization, or other event affecting any Guarantor.

Section 5.2 Notices. Any notice or demand to any Guarantor under or in connection with this Guaranty may be given at the address for the Guarantors set forth on the signature page hereto and shall conclusively be deemed and considered to have been given and received in accordance with Section 10.1 of the Credit Agreement.

Section 5.3 Business and Financial Information.

(a) THIS GUARANTY SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

(b) EACH GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE SUPREME COURT OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY OR ANY LOAN DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE OR, TO THE EXTENT PERMITTED BY LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT SHALL AFFECT ANY RIGHT THAT THE AGENTS OR ANY LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT AGAINST A GUARANTOR OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

(c) EACH GUARANTOR HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY LEGALLY AND EFFECTIVELY DO SO, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT IN ANY COURT REFERRED TO IN PARAGRAPH (b) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

(d) EACH PARTY TO THIS AGREEMENT IRREVOCABLY CONSENTS TO SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY TO THIS AGREEMENT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

(e) EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A

TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTY, ANY OTHER LOAN DOCUMENT OR THE FINANCING TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS GUARANTY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 5.5 Invalidity. In the event that any one or more of the provisions contained in this Guaranty shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Guaranty.

This Guaranty shall remain in full force and effect with respect to each Guarantor not released herefrom pursuant to the preceding sentence.
