Within the limits of each US Lender’s US Commitment or its Applicable Percentage of the US Borrowing Base, the US Borrower may from time to time borrow, prepay pursuant to Section 2.7, and reborrow under this Section 2.1(a).

     (b) Canadian Commitment. Each Canadian Lender severally agrees, on the terms and conditions set forth in this Agreement, to make Canadian Advances to the Canadian Borrower from time to time on any Business Day during the period from the Effective Date until the Maturity Date; provided that after giving effect to such Canadian Advances, the aggregate Canadian Outstandings shall not exceed the Credit Amount. Within the limits of each Canadian Lender’s Canadian Commitment or its Applicable Percentage of the Canadian Borrowing Base, the Canadian Borrower may from time to time borrow, prepay pursuant to Section 2.7, and reborrow under this Section 2.1(b).

     (c) Reduction of Commitments.

     (i) US Commitments. The US Borrower shall have the right, upon at least 10 Business Days’ irrevocable notice to the US Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the US Commitments; provided that (A) each partial reduction shall be in the aggregate amount of $1,000,000 and in integral multiples of $1,000,000 in excess thereof; (B) a notice of termination of the US Commitments delivered by the US 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 US Borrower (by notice to the US Administrative Agent on or prior to the specified effective date) if such condition is not satisfied; (C) any reduction or termination of the US Commitments pursuant to this Section shall be permanent, with no obligation of the US Lenders to reinstate such US Commitments, and the unused fees shall thereafter be computed on the basis of the US Commitments, as so reduced; and (D) a termination of the total US Commitments must also terminate the total Canadian Commitments.

     (ii) Canadian Commitments. The Canadian Borrower shall have the right, upon at least 10 Business Days’ irrevocable notice to the Canadian Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Canadian Commitments; provided that (A) each partial reduction shall be in the aggregate amount of $1,000,000 and in integral multiples of $1,000,000 in excess thereof; (B) a notice of termination of the Canadian Commitments delivered by the Canadian 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 Canadian Borrower (by notice to the Canadian Administrative Agent on or prior to the specified effective date) if such condition is not satisfied; and (C) any reduction or termination of the Canadian Commitments pursuant to this Section shall be permanent, with no obligation of the Canadian Lenders to reinstate such Canadian Commitments, and the unused fees shall thereafter be computed on the basis of the Canadian Commitments, as so reduced.

     (d) Reallocation of Commitments. Any Multiple Lender may agree with the Borrowers to reallocate its existing US Commitment or Canadian Commitment, so long as the sum of such US Commitment and Canadian Commitment remains unchanged; provided that, the aggregate amount of all Canadian Commitments, after giving effect to any reallocation, shall not exceed $25,000,000 at any time without the consent of the US Administrative Agent and shall not exceed $75,000,000 at any time without the consent of the US Administrative Agent and the US Majority Lenders. In addition, any US Lender may agree with the Borrowers to convert a portion of its US Commitment into a Canadian Commitment, thereby becoming a Multiple Lender, and any Canadian Lender may agree with the Borrowers to convert a portion of its Canadian Commitment into a US Commitment, thereby becoming a Multiple Lender, in each case so long as (x) each Lender continues to be a US Lender with a US Commitment of at least

$1,000,000, (y) the sum of such Lender’s US Commitment and Canadian Commitment remains equal to the aggregate amount of such Lender’s US Commitment and Canadian Commitment, as the case may be, prior to such reallocation and (z) the aggregate amount of all Canadian Commitments, after giving effect to any reallocation, shall not exceed $25,000,000 at any time without the consent of the US Administrative Agent and shall not exceed $75,000,000 at any time without the consent of the US Administrative Agent and the US Majority Lenders. The Borrowers shall give written notice to the Administrative Agents of any reallocation pursuant to this provision at least ten (10) Business Days prior to the effective date of any such reallocation. No applicable Lender affected by such reallocation shall be required to agree to any such reallocation, but may do so at its option, in its sole absolute discretion. The following conditions precedent must be satisfied prior to any such reallocation becoming effective:

     (i) no Default shall have occurred and be continuing;

     (ii) if, as a result of any such reallocation, the aggregate US Outstandings would exceed the Credit Amount, then the US Borrower shall, on the effective date of such reallocation, repay or prepay US Advances and US Swingline Advances, deposit cash in the US Cash Collateral Account, or cause to be issued an irrevocable standby letter of credit in favor of the US Issuing Lender (or the Underlying Issuer) and issued by a bank or other financial institution acceptable to the US Issuing Lender (or the Underlying Issuer), in an aggregate principal amount, such that, after giving effect thereto, the aggregate US Outstandings shall not exceed the Credit Amount;

     (iii) if, as a result of any such reallocation, the aggregate Canadian Outstandings would exceed the Credit Amount, then the Canadian Borrower shall, on the effective date of such reallocation, repay or prepay Canadian Advances, deposit cash in the Canadian Cash Collateral Account, or cause to be issued an irrevocable standby letter of credit in favor of the Canadian Issuing Lender and issued by a bank or other financial institution acceptable to the Canadian Issuing Lender, in an aggregate principal amount, such that, after giving effect thereto, the aggregate Canadian Outstandings shall not exceed the Credit Amount;

     (iv) Borrowers shall have paid any amounts (or deposited cash in the applicable Cash Collateral Account, or caused to be issued an irrevocable standby letter of credit in favor of the Applicable Issuing Lender and issued by a bank or other financial institution acceptable to such Issuing Lender (or the Underlying Issuer)) due under Section 2.7(c)(i) hereof on the date of such reallocation; and

     (v) Participations by the Lenders in the outstanding Letters of Credit and the Letter of Credit Obligations and the outstanding Advances of the Lenders shall be adjusted to give effect to such reallocation.

     (e) Existing Advances.

     (i) US Advances and US Swingline Advances. Without any further action on the part of either Borrower or the Lenders and so long as all conditions set forth in Section 3.1 and 3.2 have been met, the US Borrower hereby requests that, on the Effective Date, the US Lenders make the US Advances (as Adjusted Base Rate Advances) in the necessary amount to, and apply the proceeds of such US Advances to, (i) repay all outstanding “US Revolving Advances” under, and as defined in, the Restated Agreement, (ii) pay all fees owing to the Lenders or the Administrative Agent as required under the Fee Letter and (iii) pay such other fees, costs, and accounts detailed in the initial Notice of Borrowing delivered to the Administrative Agent. On the Effective Date, all Interest Periods under the Restated Agreement in respect of any Eurocurrency Advances under, and as defined in, the Restated Agreement shall automatically be terminated (and the US Borrower shall, on

the Effective Date, also pay any amounts required under Section 2.12 of the Restated Agreement). Without any further action on the part of either Borrower or the Lenders and so long as all conditions set forth in Section 3.1 and 3.2 have been met, all outstanding “US Swingline Advance” under and as defined in, the Restated Agreement are deemed to be outstanding as US Swingline Advances hereunder.

     (ii) Canadian Advances and Canadian Swingline Advances. Without any further action on the part of either Borrower or the Lenders and so long as all conditions set forth in Section 3.1 and 3.2 have been met, the Canadian Borrower hereby requests that, on the Effective Date, the Canadian Lenders make the Canadian Advances in the necessary amount to, and apply the proceeds of such Canadian Advances to, (i) repay all outstanding “Canadian Advances” and “Canadian Swingline Advances” under, and as defined in, the Restated Agreement, and (ii) pay such other fees, costs, and accounts detailed in the initial Notice of Borrowing delivered to the Administrative Agent. On the Effective Date, all Contract Periods under the Restated Agreement in respect of any Eurocurrency Advances under, and as defined in, the Restated Agreement shall automatically be terminated (and the US Borrower shall, on the Effective Date, also pay any amounts required under Section 2.12 of the Restated Agreement).

     (f) Increase in Commitments.

     (i) At any time prior to the Maturity Date, the Borrowers may effectuate up to two separate increases in the aggregate Commitments (each such increase being a “Commitment Increase”), by designating either one or more of the existing Lenders (each of which, in its sole discretion, may determine whether and to what degree to participate in such Commitment Increase) or one or more other banks or other financial institutions (reasonably acceptable to the Applicable Administrative Agent and the Applicable Issuing Lender) that at the time agree, in the case of any such bank or financial institution that is an existing Lender to increase its US Commitment or Canadian Commitment as such Lender shall so select (an “Increasing Lender”) and, in the case of any other such bank or financial institution (an “Additional Lender”), to become a party to this Agreement; provided, however, that (A) the aggregate Canadian Commitments shall not at any time exceed $25,000,000 at any time without the consent of the US Administrative Agent and shall not exceed $75,000,000 at any time without the consent of the US Administrative Agent and the US Majority Lenders, (B) other than as set forth in clause (C) below, each Commitment Increase shall be of at least $25,000,000, (C) each Commitment Increase which only increases the aggregate Canadian Commitments shall be of at least $5,000,000, (D) the aggregate amount of all Commitment Increases shall not exceed $75,000,000, and (E) all Commitments and Advances provided pursuant to a Commitment Increase shall be available on the same terms as those applicable to the existing Commitments and Advances. The sum of the increases in the Commitments of the Increasing Lenders plus the Commitments of the Additional Lenders upon giving effect to a Commitment Increase shall not, in the aggregate, exceed the amount of such Commitment Increase. The Borrowers shall provide prompt notice of any proposed Commitment Increase pursuant to this clause (f) to the Administrative Agents and the applicable Class of Lenders. This Section 2.1(f) shall not be construed to create any obligation on any of the Administrative Agents or any of the Lenders to advance or to commit to advance any credit to any Borrower or to arrange for any other Person to advance or to commit to advance any credit to any Borrower.

     (ii) A Commitment Increase shall become effective upon (A) the receipt by each Administrative Agent of (1) an agreement in form and substance reasonably satisfactory to the Applicable Administrative Agent signed by the Applicable Borrower, each Increasing Lender and each Additional Lender, setting forth the Commitments, if any, of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all

the terms and provisions hereof binding upon each Lender, and (2) such evidence of appropriate authorization on the part of the Borrowers with respect to such Commitment Increase as the Applicable Administrative Agent may reasonably request, (B) the funding by each Increasing Lender and Additional Lender of the Advances to be made by each such Lender to effect the prepayment requirement set forth in Section 2.7(c)(iv), and (C) receipt by the US Administrative Agent of a certificate of an authorized officer of the US Borrower stating that, both before and after giving effect to such Commitment Increase, no Default has occurred and is continuing, and that all representations and warranties made by the Borrowers in this Agreement are true and correct in all material respects (except that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof), unless such representation or warranty relates to an earlier date which remains true and correct as of such earlier date.

     (iii) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase, all calculations and payments of interest on the Advances shall take into account the actual US Commitment and Canadian Commitment of each Lender and the principal amount outstanding of each Advance made by such Lender during the relevant period of time.

     (g) Reserves. Anything to the contrary in this Section 2.1 notwithstanding, US Administrative Agent and the Canadian Administrative Agent shall have the right to establish reserves against the respective Borrowing Base in such amounts, and with respect to such matters, as such Administrative Agent in its Permitted Discretion shall deem necessary or appropriate, including reserves with respect to (i) sums that the Company or its Subsidiaries are required to pay under any Section of this Agreement or any other Credit Document (such as taxes, assessments, insurance premiums, or, in the case of leased assets, rents or other amounts payable under such leases) and has failed to pay, and (ii) amounts owing by the Company or its Subsidiaries to any Person to the extent secured by a Lien on, or trust over, any of the Collateral (other than a Permitted Lien), which Lien or trust, in the Permitted Discretion of such Administrative Agent likely would have a priority superior to such Administrative Agent’s Liens granted pursuant to the Credit Documents (such as Liens or trusts in favor of landlords, warehousemen, carriers, mechanics, materialmen, laborers, or suppliers, or Liens or trusts for ad valorem, excise, sales, or other taxes where given priority under applicable law) in and to such item of the Collateral.

Section 2.2 Evidence of Indebtedness.

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

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

     (c) Except for any B/A Advances (the compensation for which is set forth in Section 2.5), each Advance shall bear interest from and including the date made on the outstanding principal balance thereof as set forth in Section 2.10.

Section 2.3 Letters of Credit.

     (a) Commitment for Letters of Credit. Subject to the terms and conditions set forth in this Agreement and in reliance upon the agreements of the other Lenders set forth in this Section, (i) the US Issuing Lender agrees to, from time to time on any Business Day during the period from the Effective Date until the Maturity Date, issue, increase or extend the expiration date of, or cause an Underlying Issuer to issue, increase, or extend the expiration of, US Letters of Credit denominated in the Designated Currency for the account of the US Borrower or a US Subsidiary Guarantor; and (ii) the Canadian Issuing Lender agrees to, from time to time on any Business Day during the period from the Effective Date until the Maturity Date, issue, increase or extend the expiration date of, Canadian Letters of Credit denominated in a Designated Currency for the account of the Canadian Borrower or a Guarantor. If US Issuing Lender, at its option, elects to cause an Underlying Issuer to issue a requested Letter of Credit, then US Issuing Lender agrees that it will obligate itself to reimburse such Underlying Issuer (which may include, among, other means, by becoming an applicant with respect to such Letter of Credit or entering into undertakings which provide for reimbursements of such Underlying Issuer with respect to such Letter of Credit; each such obligation or undertaking, irrespective of whether in writing, a “Reimbursement Undertaking”) with respect to Letters of Credit issued by such Underlying Issuer. By submitting a request to US Issuing Lender for the issuance of a Letter of Credit, US Borrower shall be deemed to have requested that US Issuing Lender issue or that an Underlying Issuer issue the requested Letter of Credit and to have requested US Issuing Lender to issue a Reimbursement Undertaking with respect to such requested Letter of Credit if it is to be issued by an Underlying Issuer (it being expressly acknowledged and agreed by US Borrower that US Borrower is and shall be deemed to be an applicant (within the meaning of Section 5-102(a)(2) of the UCC) with respect to each Underlying Letter of Credit).

     (b) Limitations. In any event, no Letter of Credit will be issued, increased, or extended:

     (i) if such issuance, increase, or extension would cause the US Letter of Credit Exposure to exceed the lesser of (A) the US Letter of Credit Maximum Amount and (B) an amount equal to (1) the Credit Amount minus (2) the sum of the Dollar Equivalent of the aggregate outstanding US Advances plus the aggregate outstanding US Swingline Advances;

     (ii) if such issuance, increase, or extension would cause the Canadian Letter of Credit Exposure to exceed the lesser of (A) the Canadian Letter of Credit Maximum Amount and (B) an amount equal to (1) the Credit Amount minus (2) the sum of the Dollar Equivalent of the aggregate outstanding Canadian Advances plus the aggregate outstanding Canadian Swingline Advances;

     (iii) unless such Letter of Credit has an expiration date not later than 30 days prior to the Maturity Date; provided that, (A) if the US Commitments are terminated in whole pursuant to Section 2.1(d)(i), any US Letter of Credit may have an expiration date after the then resulting Maturity Date if

(1) the US Borrower shall provide Collateralization; and (B) if the Canadian Commitments are terminated in whole pursuant to Section 2.1(d)(ii), any Canadian Letter of Credit may have an expiration date after the then resulting Maturity Date if (1) the Canadian Borrower shall deposit into the Canadian Cash Collateral Account cash in an amount equal to the Canadian Letter of Credit Exposure or (2) the Canadian Borrower shall provide a replacement letter of credit (or other security) reasonably acceptable to the Canadian Administrative Agent, Canadian Issuing Lender and the Canadian Lenders in an amount equal to the Canadian Letter of Credit Exposure;

     (iv) unless such Letter of Credit is a standby or commercial letter of credit not supporting the repayment of indebtedness for borrowed money of any Person;

     (v) unless such Letter of Credit is in form and substance acceptable to the Applicable Issuing Lender in its sole discretion;

     (vi) unless the Applicable Borrower has delivered to the Applicable Issuing Lender a completed and executed applicable Letter of Credit Application; provided that, if the terms of any Letter of Credit Application conflicts with the terms of this Agreement, the terms of this Agreement shall control;

     (vii) unless such Letter of Credit is governed by (A) the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600, or (B) the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590, in either case, including any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the applicable Issuing Lender or Underlying Issuer;

     (viii) if any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the applicable Issuing Lender or Underlying Issuer from issuing, increasing or extending such Letter of Credit, or any Legal Requirement applicable to such Issuing Lender or Underlying Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such Issuing Lender or Underlying Issuer shall prohibit, or request that such Issuing Lender or Underlying Issuer refrain from, the issuance, increase or extension of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuing Lender or Underlying Issuer with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Lender is not otherwise compensated hereunder) not in effect on the Third Amendment Effective Date, or shall impose upon such Issuing Lender any unreimbursed loss, cost or expense which was not applicable on the Third Amendment Effective Date and which such Issuing Lender or Underlying Issuer in good ▇▇▇▇▇ ▇▇▇▇▇ material to it;

     (ix) if the issuance, increase or extension of such Letter of Credit would violate one or more policies of such Issuing Lender or Underlying Issuer applicable to letters of credit generally; or

     (x) any Lender is at such time a Defaulting Lender or a Potential Defaulting Lender hereunder, unless the applicable Issuing Lender or Underlying Issuer has entered into satisfactory arrangements with the Borrowers or such Lender to eliminate such Issuing Lender’s risk with respect to such Lender.

Furthermore, anything contained herein to the contrary notwithstanding, the US Issuing Lender may, but shall not be obligated to, issue or cause the issuance of a Letter of Credit or to issue a Reimbursement Undertaking in respect of an Underlying Letter of Credit, in either case, that supports the obligations of the US Borrower or its Subsidiaries in respect of (1) a lease of real property, or (2) an employment

contract if the US Issuing Lender reasonably determines that the Company’s obligation to reimburse any draws under such Letter of Credit may be limited.

     (c) Requesting Letters of Credit. Each Letter of Credit Extension shall be made pursuant to a Letter of Credit Application, or if applicable, amendments to such Letter of Credit Applications, given by the Applicable Borrower to the Applicable Administrative Agent for the benefit of the Applicable Issuing Lender by telecopy or in writing not later than (i) 11:00 a.m. (Houston, Texas, time) / 12:00 p.m. (Atlanta, Georgia, time) on the third Business Day before the proposed date of the US Letter of Credit Extension and (ii) 11:00 a.m. (Calgary, Alberta Canada, time) on the third Business Day before the proposed date of the Canadian Letter of Credit Extension. Each Letter of Credit Application, or if applicable, amendments to such Letter of Credit Applications, shall be fully completed and shall specify the information required therein. Each Letter of Credit Application, or if applicable, amendments to such Letter of Credit Applications, shall be irrevocable and binding on the Applicable Borrower. Subject to the terms and conditions hereof, the Applicable Issuing Lender shall (i) before 2:00 p.m. (Houston, Texas, time) / 3:00 p.m. (Atlanta, Georgia, time) on the date of such US Letter of Credit Extension and (ii) before 2:00 p.m. (Calgary, Alberta Canada, time) on the date of such Canadian Letter of Credit Extension, make such Letter of Credit Extension to the beneficiary of such Letter of Credit.

     (d) Reimbursements for Letters of Credit; Funding of Participations.

     (i) In accordance with the related Letter of Credit Application, the US Borrower with respect to a US Letter of Credit and the Canadian Borrower with respect to Canadian Letters of Credit, each agrees to pay on demand to Applicable Administrative Agent on behalf of the Applicable Issuing Lender an amount equal to any amount paid by such Applicable Issuing Lender under such Letter of Credit. Upon the Applicable Issuing Lender’s demand for payment under the terms of a Letter of Credit Application, the Applicable Borrower may request that such Borrower’s obligations to the Applicable Issuing Lender thereunder be satisfied with the proceeds of (A) a US Base Rate Advance under the US Facility in the same amount with respect to US Letters of Credit, (B) a Canadian Base Rate (C$) Advance in the same amount with respect to Canadian Letters of Credit denominated in Canadian Dollars, and (C) a Canadian Base Rate (US$) Advance in the same amount with respect to Canadian Letters of Credit denominated in Dollars, (notwithstanding any minimum size or increment limitations on individual Advances). If the Applicable Borrower does not make such request and does not otherwise make the payments demanded by the Applicable Issuing Lender as required under this Agreement or the applicable Letter of Credit Application, then the Applicable Borrower shall be deemed for all purposes of this Agreement to have requested such US Advance, or such Canadian Advance, as the case may be, in the same amount and the transfer of the proceeds thereof to satisfy such Borrower’s obligations to Applicable Issuing Lender. The US Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the US Lenders to make such US Base Rate Advances, to transfer the proceeds thereof to the US Issuing Lender (or the Underlying Issuer) in satisfaction of such obligations, and to record and otherwise treat such payments as a US Base Rate Advance under the US Facility to the US Borrower. The Canadian Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Canadian Lenders to make such Canadian Base Rate Advances, to transfer the proceeds thereof to Canadian Issuing Lender in satisfaction of such obligations, and to record and otherwise treat such payments as a Canadian Base Rate Advance to the Canadian Borrower. Each Administrative Agent and each Lender may record and otherwise treat the making of such Borrowings as the making of (1) a US Borrowing to the US Borrower under this Agreement as if requested by the US Borrower with respect to US Letter of Credit Obligations and (2) a Canadian Borrowing in the same Designated Currency as the applicable Canadian Letters of Credit to the Canadian Borrower under this Agreement as if requested by the Canadian Borrower with respect to Canadian Letter of Credit Obligations. Nothing herein is intended to release any of any Borrower’s obligations under any Letter of Credit Application, but only to provide an additional

method of payment therefor. The making of any Borrowing under this Section 2.3(d) shall not constitute a cure or waiver of any Default or Event of Default, other than the payment Default or Event of Default which is satisfied by the application of the amounts deemed advanced hereunder, caused by a Borrower’s failure to comply with the provisions of this Agreement or the Letter of Credit Application.

     (ii) Each Lender (including the Lender acting as an Applicable Issuing Lender) shall, upon notice from the Applicable Administrative Agent that the Applicable Borrower has requested or is deemed to have requested an Advance pursuant to Section 2.6 and regardless of whether (A) the conditions in Section 3.2 have been met, (B) such notice complies with Section 2.6, or (C) a Default exists, make funds available to the Applicable Administrative Agent (if to the US Administrative Agent, then to the US Administrative Agent’s Account) for the account of the Applicable Issuing Lender in an amount equal to such Lender’s Applicable Percentage of the amount of such Advance not later than 1:00 p.m. (Houston, Texas, time or Calgary, Alberta Canada, time, as applicable) on the Business Day specified in such notice by the Applicable Administrative Agent, whereupon (i) each US Lender that so makes funds available shall be deemed to have made a US Base Rate Advance under the US Facility to the US Borrower in such amount, and (b) each Canadian Lender that so makes funds available shall be deemed to have made a Canadian Base Rate (C$) Advance or Canadian Base Rate (US$) Advance, as applicable, to the Canadian Borrower in such amount. The Applicable Administrative Agent shall remit the funds so received to the Applicable Issuing Lender.

     (iii) If any such Lender shall not have so made such Advance available to the Applicable Administrative Agent pursuant to this Section 2.3, such Lender agrees to pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Overnight Rate for such day for the first three days and thereafter the interest rate applicable to such US Base Rate Advances, or if applicable, the Canadian Base Rate Advances and (B) the Maximum Rate. Whenever, at any time after the Applicable Administrative Agent has received from any Lender such Lender’s Advance, the Applicable Administrative Agent receives any payment on account thereof, the Applicable Administrative Agent will pay to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s Advance was outstanding and funded), which payment shall be subject to repayment by such Lender if such payment received by the Applicable Administrative Agent is required to be returned. Each Lender’s obligation to make the Advances pursuant to this Section 2.3 shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any set-off, counterclaim, recoupment, defense or other right which such Lender or any other Person may have against any Applicable Issuing Lender, any Administrative Agent or any other Person for any reason whatsoever; (2) the occurrence or continuance of a Default or the termination of the Commitments; (3) any breach of this Agreement by a Borrower or any other Lender; or (4) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

     (e) Participations. Upon the date of the issuance or increase of a Letter of Credit or the deemed issuance of the Existing Letters of Credit under Section 2.3(k), (i) the US Issuing Lender shall be deemed to have sold to each other US Lender and each other US Lender shall have been deemed to have purchased from the US Issuing Lender a participation in the related US Letter of Credit Obligations (including the related Reimbursement Undertaking) equal to such US Lender’s Applicable Percentage at such date, and (ii) the Canadian Issuing Lender shall be deemed to have sold to each other Canadian Lender and each other Canadian Lender shall have been deemed to have purchased from the Canadian Issuing Lender a participation in the related Canadian Letter of Credit Obligations equal to such Canadian Lender’s Applicable Percentage at such date, and, in either case, such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The Applicable Issuing Lender shall promptly notify

each such participant Lender by telex, telephone, or telecopy of each Letter of Credit issued or increased and the actual dollar amount of such Lender’s participation in such Letter of Credit.

     (f) Obligations Unconditional. The obligations of the US Borrower under this Agreement in respect of each US Letter of Credit, and the obligations of the Canadian Borrower under this Agreement in respect of each Canadian Letter of Credit, shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances:

     (i) any lack of validity or enforceability of any Letter of Credit Documents;

     (ii) any amendment or waiver of or any consent to departure from any Letter of Credit Documents;

     (iii) the existence of any claim, set-off, defense or other right which any Borrower may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), any Issuing Lender, any Underlying Issuer, any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction;

     (iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect to the extent any Issuing Lender or any Underlying Issuer would not be liable therefor pursuant to the following paragraph (h);

     (v) payment by any Issuing Lender or any Underlying Issuer under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

     (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing;

provided, however, that nothing contained in this paragraph (f) shall be deemed to constitute a waiver of any remedies of the Borrowers in connection with the Letters of Credit.

     (g) Prepayments of Letters of Credit. In the event that any US Letter of Credit shall be outstanding or shall be drawn and not reimbursed after the Maturity Date, the US Borrower shall provide Collateralization to the US Administrative Agent. In the event that any Canadian Letter of Credit shall be outstanding or shall be drawn and not reimbursed after the Maturity Date, the Canadian Borrower shall provide Collateralization to the Canadian Administrative Agent.

     (h) Liability of Issuing Lenders and Underlying Issuers. The US Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any US Letter of Credit with respect to its use of such Letter of Credit. The Canadian Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Canadian Letter of Credit with respect to its use of such Letter of Credit. Neither Issuing Lender, nor any Underlying Issuer, nor any of their respective officers or directors shall be liable or responsible for:

     (i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

     (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged;

     (iii) payment by any Issuing Lender or Underlying Issuer against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

     (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING AN ISSUING LENDER’S OR AN UNDERLYING ISSUER’S OWN NEGLIGENCE),

except that the Applicable Borrower shall have a claim against the Applicable Issuing Lender, and the Applicable Issuing Lender shall be liable to, and shall promptly pay to, the Applicable Borrower, to the extent of any direct, as opposed to consequential, damages suffered by such Borrower which such Borrower proves were caused by (A) such Issuing Lender’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) such Issuing Lender’s willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Lenders and the Underlying Issuers may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

     (i) Cash Collateral Account.

     (i) If the US Borrower is required to deposit funds in the US Cash Collateral Account pursuant to the terms hereof, then the US Borrower and the US Administrative Agent shall establish the US Cash Collateral Account and the US Borrower shall execute any documents and agreements, including the US Administrative Agent’s standard form assignment of deposit accounts, that the US Administrative Agent requests in connection therewith to establish the US Cash Collateral Account and grant the US Administrative Agent an Acceptable Security Interest in such account and the funds therein. The US Borrower hereby pledges to the US Administrative Agent and grants the US Administrative Agent a security interest in the US Cash Collateral Account, whenever established, all funds held in the US Cash Collateral Account from time to time, and all proceeds thereof as security for the payment of the Obligations.

     (ii) If the Canadian Borrower is required to deposit funds in the Canadian Cash Collateral Account pursuant to the terms hereof, then the Canadian Borrower and the Canadian Administrative Agent shall establish the Canadian Cash Collateral Account and the Canadian Borrower shall execute any documents and agreements, including the Canadian Administrative Agent’s standard form assignment of deposit accounts, that the Canadian Administrative Agent requests in connection therewith to establish the Canadian Cash Collateral Account and grant the Canadian Administrative Agent an Acceptable Security Interest in such account and the funds therein. The Canadian Borrower hereby pledges to the Canadian Administrative Agent and grants the Canadian Administrative Agent a security interest in the Canadian Cash Collateral Account, whenever established, all funds held in the Canadian Cash Collateral Account from time to time, and all proceeds thereof as security for the payment of the Canadian Obligations.

     (iii) Funds held in the Cash Collateral Accounts shall be held as cash collateral for obligations with respect to US Letters of Credit in the case of the US Cash Collateral Account and the Canadian Letters of Credit in the case of the Canadian Cash Collateral Account. Such funds shall be promptly

applied by the Applicable Administrative Agent at the request of the Applicable Issuing Lender to any reimbursement or other obligations under the applicable Letters of Credit that exist or occur. To the extent that any surplus funds are held in the US Cash Collateral Account above the US Letter of Credit Exposure during the existence of an Event of Default the US Administrative Agent may (A) hold such surplus funds in the US Cash Collateral Account as cash collateral for the Obligations or (B) apply such surplus funds to any Obligations in any manner directed by the Majority Lenders. To the extent that any surplus funds are held in the Canadian Cash Collateral Account above the Canadian Letter of Credit Exposure during the existence of an Event of Default the Canadian Administrative Agent may (A) hold such surplus funds in the Canadian Cash Collateral Account as cash collateral for the Canadian Obligations or (B) apply such surplus funds to any such Obligations in any manner directed by the Canadian Majority Lenders. If no Default exists, the Administrative Agents shall release to the Applicable Borrower at such Borrower’s written request any funds held in the applicable Cash Collateral Account above the amounts required by 2.3(i).

     (iv) Funds held in the US Cash Collateral Account shall be invested in Liquid Investments maintained with, and under the sole dominion and control of, the US Administrative Agent or in another investment if mutually agreed upon by the US Borrower and the US Administrative Agent, but the US Administrative Agent shall have no other obligation to make any other investment of the funds therein. Funds held in the Canadian Cash Collateral Account shall be invested in Liquid Investments maintained with, and under the sole dominion and control of, the Canadian Administrative Agent or in another investment if mutually agreed upon by the Canadian Borrower and the Canadian Administrative Agent, but the Canadian Administrative Agent shall have no other obligation to make any other investment of the funds therein. The Administrative Agents shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Accounts and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which such Administrative Agent accords its own property, it being understood that neither Administrative Agent shall have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

     (v) If any Lender becomes, and during the period it remains, a Defaulting Lender or a Potential Defaulting Lender, if any Letter of Credit or Swingline Advance is at the time outstanding, the applicable Issuing Lender and Swingline Lender, as the case may be, by notice to the Borrowers and such Defaulting Lender or Potential Defaulting Lender through the Applicable Administrative Agent, may require the applicable Borrower to cash collateralize the obligations of the applicable Borrower to such Issuing Lender or Swingline Lender in respect of such Letter of Credit or Swingline Advance in amount at least equal to the aggregate amount of the obligations (contingent or otherwise) of such Defaulting Lender or such Potential Defaulting Lender in respect thereof, or to make other arrangements satisfactory to the Applicable Administrative Agent, and to such Issuing Lender and the Swingline Lender, as the case may be, in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender or Potential Defaulting Lender.

     (j) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary of the US Borrower or a Subsidiary of the Canadian Borrower, (i) the US Borrower shall be obligated to reimburse the US Issuing Lender or the Underlying Issuer hereunder for any and all drawings under such Letter of Credit issued under the US Facility by the US Issuing Lender or Underlying Issuer and (ii) the Canadian Borrower shall be obligated to reimburse the Canadian Issuing Lender hereunder for any and all drawings under such Letter of Credit issued under the Canadian Facility by the Canadian Issuing Lender. The US Borrower hereby acknowledges that the issuance of Letters of Credit for the account of its Subsidiaries inures to the benefit of the US Borrower, and that the US Borrower’s business derives substantial benefits from the businesses of such Subsidiaries. The Canadian Borrower hereby acknowledges that the issuance

of Letters of Credit for the account of its Subsidiaries inures to the benefit of the Canadian Borrower, and that the Canadian Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

     (k) Existing Letters of Credit. (i) The US Issuing Lender, the US Lenders and the US Borrower agree that effective as of the Effective Date, the Existing US Letters of Credit shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement. The Canadian Issuing Lender, the Canadian Lenders and the Canadian Borrower agree that effective as of the Effective Date, the Existing Canadian Letters of Credit shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement. (ii) The US Borrower and each other party hereto hereby acknowledge and agree that all Letters of Credit issued and outstanding on the Third Amendment Effective Date shall constitute Letters of Credit under this Agreement on and after the Third Amendment Effective Date with the same effect as if such Letters of Credit were issued by the Issuing Lender or an Underlying Issuer at the request of US Borrower on the Third Amendment Effective Date.

     (l) Underlying Issuer and Letters of Credit.

     (i) US Borrower agrees to be bound by the Underlying Issuer’s regulations and interpretations of any Letter of Credit or by US Issuing Lender’s interpretations of any Reimbursement Undertaking even though this interpretation may be different from US Borrower’s own, and US Borrower understands and agrees that none of the US Issuing Lender, any Secured Party, or any Underlying Issuer shall be liable for any error, negligence, or mistake, whether of omission or commission, in following US Borrower’s instructions or those contained in the Letter of Credit or any modifications, amendments, or supplements thereto. US Borrower understands that the Reimbursement Undertakings may require US Issuing Lender to indemnify the Underlying Issuer for certain costs or liabilities arising out of claims by US Borrower against such Underlying Issuer. US BORROWER HEREBY AGREES TO INDEMNIFY, SAVE, DEFEND, AND HOLD US ISSUING LENDER AND EACH OTHER SECURED PARTY HARMLESS WITH RESPECT TO ANY LOSS, COST, EXPENSE (INCLUDING REASONABLE ATTORNEYS FEES), OR LIABILITY INCURRED BY THEM AS A RESULT OF THE US ISSUING LENDER’S INDEMNIFICATION OF AN UNDERLYING ISSUER; PROVIDED, HOWEVER, THAT US BORROWER SHALL NOT BE OBLIGATED HEREUNDER TO INDEMNIFY FOR ANY SUCH LOSS, COST, EXPENSE, OR LIABILITY TO THE EXTENT THAT IT IS CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE US ISSUING LENDER. Borrower hereby acknowledges and agrees that none of the US Issuing Lender, any Secured Party, or any Underlying Issuer shall be responsible for delays, errors, or omissions resulting from the malfunction of equipment in connection with any Letter of Credit.

     (ii) US Borrower hereby authorizes and directs any Underlying Issuer to deliver to the US Issuing Lender all instruments, documents, and other writings and property received by such Underlying Issuer pursuant to such Underlying Letter of Credit and to accept and rely upon the US Issuing Lender’s instructions with respect to all matters arising in connection with such Underlying Letter of Credit and the related application.

     (iii) Any and all issuance charges, commissions, fees, and costs incurred by the US Issuing Lender relating to Underlying Letters of Credit shall be Lender Group Expenses for purposes of this Agreement and shall be reimbursable immediately by US Borrower to US Administrative Agent for the account of the US Issuing Lender; it being acknowledged and agreed by US Borrower that the Underlying Issuer may impose a schedule of charges for amendments, extensions, drawings, and renewals.

Section 2.4 Swingline Advances.

     (a) Subfacility. On the terms and conditions set forth in this Agreement, (i) the US Swingline Lender may, but is not obligated to, from time-to-time on any Business Day from the Effective Date until the last Business Day occurring before the Maturity Date, make US Swingline Advances in Dollars to the US Borrower in an aggregate principal amount not to exceed the US Swingline Amount at any time, and (ii) the Canadian Swingline Lender may, but is not obligated to, from time-to-time on any Business Day from the Effective Date until the last Business Day occurring before the Maturity Date, make Canadian Swingline Advances in Canadian Dollars to the Canadian Borrower in an aggregate principal amount not to exceed the Canadian Swingline Amount outstanding at any time; provided that (A) after giving effect to such Swingline Advance, the US Outstandings and the Canadian Outstandings shall not exceed the applicable Credit Amount in effect at such time, (B) no Swingline Advance may mature after the Maturity Date, and (C) no Swingline Advance shall be made by either Swingline Lender if the conditions set forth in Section 3.2 have not been met as of the date of such Swingline Advance. The Borrowers agree that the giving of the applicable Notice of Borrowing and the acceptance by the Applicable Borrower of the proceeds of such Swingline Advance shall constitute a representation and warranty by the such Borrower that on the date of such Swingline Advance the conditions set forth in Section 3.2 have been met.

     (b) Evidence of Indebtedness. The indebtedness of the US Borrower to the US Swingline Lender resulting from US Swingline Advances, and the indebtedness of the Canadian Borrower to the Canadian Swingline Lender resulting from Canadian Swingline Advances shall be evidenced as set forth in Section 2.2.

     (c) Prepayment. Within the limits expressed in this Agreement and subject to the applicable Swingline Lender’s sole discretion, amounts advanced pursuant to Section 2.4(a) may from time to time be borrowed, prepaid without penalty, and reborrowed. If the amount of aggregate outstanding amount of US Swingline Advances ever exceeds the US Swingline Amount, the US Borrower shall, upon receipt of written notice of such condition from the US Swingline Lender and to the extent of such excess, prepay to the US Swingline Lender outstanding principal of the US Swingline Amount such that such excess is eliminated. If the Canadian Dollar Equivalent amount of the aggregate outstanding amount of Canadian Swingline Advances ever exceeds the Canadian Swingline Amount, the Canadian Borrower shall, upon receipt of written notice of such condition from the Canadian Swingline Lender and to the extent of such excess, prepay to the Canadian Swingline Lender outstanding principal of the Canadian Swingline Amount such that such excess is eliminated.

     (d) Refinancing of Swingline Advances.

     (i) The US Swingline Lender at any time in its sole and absolute discretion may request, on behalf of the US Borrower (which hereby irrevocably authorizes such Swingline Lender to so request on its behalf), that each US Lender make a US Base Rate Advance under the US Facility in an amount equal to such Lender’s Applicable Percentage of the amount of US Swingline Advances then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Notice of Borrowing for purposes hereof), without regard to the minimum and multiples specified in Section 2.6(c) for the principal amount of US Borrowings but subject to the unutilized portion of the US Commitments and the conditions set forth in Section 3.2. The US Swingline Lender shall furnish the US Borrower with a copy of the applicable Notice of Borrowing promptly after delivering such notice to the US Administrative Agent. Regardless of whether the request for such US Base Rate Advance complies with Section 2.6, each US Lender shall make an amount equal to its Applicable Percentage of the amount specified in such Notice of Borrowing available to the US Administrative Agent in Same Day Funds to the US Administrative Agent’s Account for the account of the US Swingline Lender at the US Administrative Agent’s Lending Office for Dollar-denominated

payments not later than 1:00 p.m. on the day specified in such Notice of Borrowing, whereupon, subject to Section 2.4(d)(iii), each US Lender that so makes funds available shall be deemed to have made a US Base Rate Advance under the US Facility to the US Borrower in such amount. The US Administrative Agent shall remit the funds so received to the US Swingline Lender.

     (ii) The Canadian Swingline Lender at any time in its sole and absolute discretion may request, on behalf of the Canadian Borrower (which hereby irrevocably authorizes such Swingline Lender to so request on its behalf), that each Canadian Lender make a Canadian Base Rate (C$) Advance denominated in an amount equal to such Lender’s Applicable Percentage of the amount of Canadian Swingline Advances then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Notice of Borrowing for purposes hereof), without regard to the minimum and multiples specified in Section 2.6(c) for the principal amount of Canadian Borrowings but subject to the unutilized portion of the Canadian Commitments and the conditions set forth in Section 3.2. The Canadian Swingline Lender shall furnish the Canadian Borrower with a copy of the applicable Notice of Borrowing promptly after delivering such notice to the Canadian Administrative Agent. Regardless of whether the request for such Canadian Base Rate (C$) Advance complies with Section 2.6, each Canadian Lender shall make an amount equal to its Applicable Percentage of the amount specified in such Notice of Borrowing available to the Canadian Administrative Agent in Same Day Funds for the account of the Canadian Swingline Lender at the Canadian Administrative Agent’s Lending Office for Canadian Dollar-denominated payments not later than 1:00 p.m. on the day specified in such Notice of Borrowing, whereupon, subject to Section 2.4(d)(iii), each Canadian Lender that so makes funds available shall be deemed to have made a Canadian Base Rate (C$) Advance to the Canadian Borrower in such amount. The Canadian Administrative Agent shall remit the funds so received to the Canadian Swingline Lender.

     (iii) If for any reason any Swingline Advance cannot be refinanced by such a US Borrowing or Canadian Borrowing, as applicable, in accordance with Section 2.4(d)(i) or Section 2.4(d)(ii), the applicable Notice of Borrowing submitted by the Applicable Swingline Lender as set forth herein shall be deemed to be a request by such Swingline Lender that each of the applicable Lenders fund its risk participation in the relevant Swingline Advances (with respect to US Swingline Advances, to the US Administrative Agent’s Account) and each such Lender’s payment to the Applicable Administrative Agent for the account of the Applicable Swingline Lender pursuant to Section 2.4(d)(i) or Section 2.4(d)(ii) shall be deemed payment in respect of such participation.

     (iv) If any Lender fails to make available to the Applicable Administrative Agent for the account of the Applicable Swingline Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.4(d) by the time specified in Section 2.4(d)(i) or Section 2.4(d)(ii), the Applicable Swingline Lender shall be entitled to recover from such Lender (acting through the Applicable Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to such Swingline Lender at a rate per annum equal to the applicable Overnight Rate from time to time in effect. A certificate of the Applicable Swingline Lender submitted to any Lender (through the Applicable Administrative Agent) with respect to any amounts owing under this clause (iv) shall be conclusive absent manifest error.

     (v) Each Lender’s obligation to make Advances or to purchase and fund risk participations in Swingline Advances pursuant to this Section 2.4(d) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against any Swingline Lender, the US Borrower, the Canadian Borrower, or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the

foregoing; provided, however, that each Lender’s obligation to make Advances pursuant to Section 2.4(d)(i) or 2.4(d)(ii) is subject to the conditions set forth in Section 3.2. No such funding of risk participations shall (1) relieve or otherwise impair the obligation of the US Borrower to repay the US Swingline Advances, together with interest as provided herein, or (2) relieve or otherwise impair the obligation of the Canadian Borrower to repay the Canadian Swingline Advances, together with interest as provided herein.

     (e) Repayment of Participations.

     (i) At any time after any Lender has purchased and funded a risk participation in a Swingline Advance, if the Applicable Swingline Lender receives any payment on account of such Swingline Advance, the Applicable Swingline Lender will distribute to such Lender its Applicable Percentage of such payment (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s risk participation was funded) in the same funds as those received by the Applicable Swingline Lender.

     (ii) If any payment received by the Applicable Swingline Lender in respect of principal or interest on any Swingline Advance is required to be returned by such Swingline Lender under any of the circumstances described in Section 9.13 (including pursuant to any settlement entered into by such Swingline Lender in its discretion), each Lender shall pay to the Applicable Swingline Lender its Applicable Percentage thereof on demand of the Applicable Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the applicable Overnight Rate. The Applicable Administrative Agent will make such demand upon the request of the Applicable Swingline Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement.

     (f) Interest for Account of Swingline Lender. The US Swingline Lender shall charge the Loan Account, as permitted under Section 2.18, for interest on the US Swingline Advances. The Canadian Swingline Lender shall be responsible for invoicing the Canadian Borrower for interest on the Canadian Swingline Advances. Until each Lender funds its Advances or risk participation pursuant to this Section to refinance such Lender’s Applicable Percentage of the applicable Swingline Advances, interest in respect of such Applicable Percentage shall be solely for the account of the Applicable Swingline Lender.

     (g) Payments Directly to Swingline Lender. The US Borrower shall make all payments of principal and interest in respect of the US Swingline Advances directly to the US Swingline Lender. The Canadian Borrower shall make all payments of principal and interest in respect of the Canadian Swingline Advances directly to the Canadian Swingline Lender.

     (h) Method of Borrowing. Except as provided in the clause (c) above, each request for a Swingline Advance shall be made pursuant to telephone notice to the Applicable Swingline Lender given no later than 11:00 a.m. (Houston, Texas time or Calgary, Alberta Canada time) / 12:00 p.m. (Atlanta, Georgia time) on the date of the proposed Swingline Advance, promptly confirmed by a completed and executed Notice of Borrowing telecopied or facsimiled to the Applicable Administrative Agent and the Applicable Swingline Lender. The Applicable Swingline Lender will promptly make such Swingline Advance available to the Applicable Borrower at the Applicable Borrower’s account with the Applicable Administrative Agent.

     (i) Discretionary Nature of the Swing Line Facilities. Notwithstanding any terms to the contrary contained herein, each of the Swingline facilities provided herein (i) is an uncommitted facility and the Swingline Lenders may, but shall not be obligated to, make Swingline Advances, and (ii) may be

terminated at any time by the applicable Swingline Lender upon written notice to the applicable Borrower.

Section 2.5 Bankers’ Acceptances.

     (a) Subject to the terms and conditions of this Agreement, the Canadian Borrower may request a Borrowing denominated in Canadian Dollars by presenting drafts for acceptance and, if applicable, purchase as B/As by the Canadian Lenders.

     (b) No Contract Period with respect to a B/A to be accepted and, if applicable, purchased as an Advance shall extend beyond the Maturity Date. All B/A Borrowings shall be denominated in Canadian Dollars.

     (c) To facilitate availment of the B/A Advances, the Canadian Borrower hereby appoints each Canadian Lender as its attorney to sign and endorse on its behalf, in handwriting or by facsimile or mechanical signature as and when deemed necessary by such Canadian Lender, blank forms of B/As in the form requested by such Canadian Lender. The Canadian Borrower recognizes and agrees that all B/As signed and/or endorsed on its behalf by a Canadian Lender shall bind the Canadian Borrower as fully and effectually as if signed in the handwriting of and duly issued by the proper signing officers of the Canadian Borrower. Each Canadian Lender is hereby authorized to issue such B/As endorsed in blank in such face amounts as may be determined by such Canadian Lender; provided that the aggregate amount thereof is equal to the aggregate amount of B/As required to be accepted and purchased by such Canadian Lender. No Canadian Lender shall be liable for any damage, loss or other claim arising by reason of any loss or improper use of any such instrument except the gross negligence or willful misconduct of such Canadian Lender or its officers, employees, agents or representatives. Each Canadian Lender shall maintain a record with respect to B/As (i) voided by it for any reason, (ii) accepted and purchased by it hereunder and (iii) canceled at their respective maturities. Each Canadian Lender further agrees to retain such records in the manner and for the statutory periods provided in the various provincial or federal statutes and regulations which apply to such Canadian Lender. On request by or on behalf of the Canadian Borrower, a Canadian Lender shall cancel all forms of B/A which have been pre-signed or pre-endorsed on behalf of the Canadian Borrower and which are held by such Canadian Lender and are not required to be issued in accordance with the Canadian Borrower’s irrevocable notice. At the discretion of a Canadian Lender, B/As to be accepted by such Canadian Lender may be issued in the form of “Depository Bills” within the meaning of the Depository Bills and Notes Act (Canada) and deposited with the Canadian Depository for Securities Limited (“CDS”) and may be made payable to “CDS & Co.” or in such other name as may be acceptable to CDS and thereafter dealt with in accordance with the rules and procedures of CDS, consistent with the terms of this Agreement and the Depository Bills and Notes Act (Canada). All Depository Bills so issued shall be governed by the provisions of this Section 2.5.

     (d) Drafts of the Canadian Borrower to be accepted as B/As hereunder shall be signed as set forth in this Section 2.5. Notwithstanding that any Person whose signature appears on any B/A may no longer be an authorized signatory for any of the Canadian Lenders or the Canadian Borrower at the date of issuance of a B/A, such signature shall nevertheless be valid and sufficient for all purposes as if such authority had remained in force at the time of such issuance and any such B/A so signed shall be binding on the Canadian Borrower.

     (e) Promptly following receipt of a notice of borrowing, continuation or conversion of B/As, the Canadian Administrative Agent shall so advise the Canadian Lenders and shall advise each Canadian Lender of the aggregate face amount of the B/As to be accepted by it and the applicable Contract Period (which shall be identical for all Canadian Lenders). The aggregate face amount of the B/As to be accepted by a Canadian Lender shall be in an integral multiple of C$100,000 and such face amount shall

be in each Canadian Lender’s Applicable Percentage of such Canadian Borrowing, and each such Canadian Borrowing shall be no less than $1,000,000; provided, that the Canadian Administrative Agent may, in its sole discretion, increase or reduce any Canadian Lender’s portion of such B/A to the nearest C$100,000.

     (f) The Canadian Borrower may specify in a notice of borrowing or conversion or continuation pursuant to Section 2.6(a) or Section 2.6(b), respectively, that it desires that any B/As requested by such notice be purchased by the Canadian Lenders, in which case the Canadian Lenders shall purchase, or arrange the purchase of, each B/A from the Canadian Borrower at the Discount Rate for such Canadian Lender applicable to such B/A accepted by it and provide to the Canadian Administrative Agent the Discount Proceeds for the account of the Canadian Borrower. The Acceptance Fee payable by the Canadian Borrower to a Canadian Lender under Section 2.10(f) in respect of each B/A accepted by such Canadian Lender shall be set off against the Discount Proceeds payable by such Canadian Lender under this Section 2.5.

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

     (h) If a Canadian Lender notifies the Canadian Administrative Agent in writing that it is unable to accept Bankers’ Acceptances, such Canadian Lender will, instead of accepting and, if applicable, purchasing Bankers’ Acceptances, make an advance (a “B/A Equivalent Advance”) to the Canadian Borrower in the amount and for the same term as the draft that such Canadian Lender would otherwise have been required to accept and purchase hereunder. Each such Canadian Lender will provide to the Canadian Administrative Agent the Discount Proceeds of such B/A Equivalent Advance for the account of the Canadian Borrower. Each such B/A Equivalent Advance will bear interest at the same rate that would result if such Lender had accepted (and been paid an Acceptance Fee) and purchased (on a discounted basis at the Discount Rate) a Bankers’ Acceptance for the relevant Contract Period (it being the intention of the parties that each such B/A Equivalent Advance shall have the same economic consequences for the Lenders and the Canadian Borrower as the Bankers’ Acceptance which such B/A Equivalent Advance replaces). All such interest shall be paid in advance on the date such B/A Equivalent Advance is made, and will be deducted from the principal amount of such B/A Equivalent Advance in the same manner in which the Discount Proceeds of a Bankers’ Acceptance would be deducted from the face amount of the Bankers’ Acceptance.

     (i) The Canadian Borrower waives presentment for payment and any other defense to payment of any amounts due to a Canadian Lender in respect of a B/A accepted and purchased by it pursuant to this Agreement which might exist solely by reason of such B/A being held, at the maturity thereof, by such Canadian Lender in its own right and the Canadian Borrower agrees not to claim any days of grace if such Canadian Lender as holder sues the Canadian Borrower on the B/A for payment of the amount payable by the Canadian Borrower thereunder. On the last day of the Contract Period of a B/A, or such earlier date as may be required or permitted pursuant to the provisions of this Agreement, the Canadian Borrower shall pay the Canadian Lender that has accepted and purchased such B/A the full face amount of such B/A (subject to Section 2.5(j) below and Section 2.7(b)), and after such payment, the Canadian Borrower shall have no further liability in respect of such B/A and such Canadian Lender shall be entitled to all benefits of, and be responsible for all payments due to third parties under, such B/A.

     (j) Except as required by any Canadian Lender upon the occurrence of an Event of Default, no B/A Advance may be repaid by the Canadian Borrower prior to the expiry date of the Contract Period applicable to such B/A Advance; provided, however, that any B/A or B/A Equivalent Advance may be defeased as provided in the proviso to Section 2.7(b).

Section 2.6 Borrowings; Procedures and Limitations.

     (a) Notice. Each Borrowing shall be made pursuant to a Notice of Borrowing and given:

     (i) by the US Borrower to the US Administrative Agent not later than 12:00 p.m. (Houston, Texas time) / 1:00 p.m. (Atlanta, Georgia time) on the fourth Business Day before the date of the proposed Borrowing in the case of a Eurocurrency Advance under the US Facility denominated in a Foreign Currency,

     (vi) by the Canadian Borrower to the Canadian Administrative Agent not later than 12:00 p.m. (Calgary, Alberta Canada time) one Business Day before the date of the proposed Borrowing in the case of a Canadian Base Rate (C$) Advance.

The Applicable Administrative Agent shall give each applicable Lender prompt notice on the day of receipt of timely Notice of Borrowing of such proposed Borrowing by telecopier; provided however that the Administrative Agents and each of the Lenders hereby waive the requirement in this Section 2.6(a) with respect to the initial Borrowing to be made on the Effective Date. Each Notice of Borrowing shall be by telephone or telecopier (and if by telephone, confirmed promptly with a written Notice of Borrowing received by the applicable Administrative Agent prior to 4:00 p.m. (Houston, Texas time) / 5:00 p.m. (Atlanta, Georgia time) on the same day), specifying the (i) requested date of such Borrowing (which shall be a Business Day), (ii) requested Type of Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing, (iv) if such Borrowing is to be comprised of Eurocurrency Advances, the Interest Period for such Advances, (v) if such Borrowing is to be comprised of B/A Advances, the Contract Period for such Advances, and (vi) the Designated Currency of such Borrowing. In the case of a proposed Borrowing comprised of Eurocurrency Advances, the Applicable Administrative Agent shall promptly notify each applicable Lender of the applicable interest rate under Section 2.10, as applicable. Each US Lender or Canadian Lender, as applicable, shall before 11:00 a.m. (Houston, Texas time or Calgary, Alberta Canada time, as applicable) on the date of the proposed Borrowing, make available for the account of its Lending Office to the Applicable Administrative Agent at its address referred to in Section 9.7 with respect to the Canadian Administrative Agent, and to the US Administrative Agent’s Account with respect to the US Administrative Agent, or such other location or accounts as the Applicable Administrative Agent may specify by notice to the applicable Lenders, in

Same Day Funds, such Lender’s Applicable Pro Rata Share of such Borrowing.

For purposes other than the conditions set forth in Section 3.2, the portion of Advances comprising part of the same Borrowing that are Converted to Advances of another Type shall constitute a new Borrowing.

     (vii) If any Lender shall, at least one Business Day prior to the requested date of any Borrowing comprised of Eurocurrency Advances or B/A Advances, notify the Applicable Administrative Agent and the Applicable Borrower that the introduction of or any change in or in the interpretation of any Legal Requirement makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations under this Agreement to make Eurocurrency Advances or B/A Advances or to fund or maintain Eurocurrency Advances or B/A Advances, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or take deposits of, Dollars or any Foreign Currency in the applicable interbank market, then (1) if the requested Borrowing was of US Advances, such Lender’s Applicable Percentage of the Dollar Equivalent amount of such Borrowing shall be made as a US Base Rate Advance of such US Lender under the US Facility, (2) if the requested Borrowing was of Canadian Advances denominated in Dollars, such Lender’s Applicable Percentage of the Dollar Equivalent amount of such Borrowing shall be made as a Canadian Base Rate (US$) Advance of such Lender, (3) if the requested Borrowing was of Canadian Advances denominated in Canadian Dollars, such Lender’s Applicable Percentage of the amount of such Borrowing shall be made as a Canadian Base Rate (C$) Advance of such Lender, (4) in any event, such US Base Rate Advance or Canadian Base Rate Advance, as applicable, shall be considered part of the same Borrowing and interest on such US Base Rate Advance or Canadian Base Rate Advance, as applicable, shall be due and payable at the same time that interest on the Eurocurrency Advances or the face amount of the B/A Advances comprising the remainder of such Borrowing shall be due and payable, and (5) any obligation of such Lender to make, continue, or Convert to, Eurocurrency Advances in the affected currency or currencies, or to make B/A Advances, including in connection with such requested Borrowing, shall be suspended until such Lender notifies

the Applicable Administrative Agent and the Applicable Borrower that the circumstances giving rise to such determination no longer exist.

     (viii) If (A) the US Administrative Agent is unable to determine the Eurocurrency Rate for Eurocurrency Advances comprising any requested US Borrowing, or (B) the Canadian Administrative Agent is unable to determine the Eurocurrency Rate for Eurocurrency Advances comprising any requested Canadian Borrowing, the right of the Applicable Borrower to select Eurocurrency Advances in the affected currency or currencies for such Borrowing or for any subsequent Borrowing shall be suspended until the Applicable Administrative Agent shall notify the Applicable Borrower and the applicable Lenders that the circumstances causing such suspension no longer exist, and each US Advance comprising such Borrowing shall be made as a US Base Rate Advance under the US Facility in the Dollar Equivalent of the originally requested Advance, and each Canadian Advance comprising such Borrowing shall be made as a Canadian Base Rate (US$) Advance in the Dollar Equivalent of the originally requested Advance.

or currencies for such Borrowing or for any subsequent Borrowing shall be suspended until the US Administrative Agent shall notify the US Borrower and the US Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be made as a US Base Rate Advance in the Dollar Equivalent of the originally requested Advance.

     (xii) If the Applicable Borrower shall fail to select the duration or continuation of any Interest Period for any Eurocurrency Advance in accordance with the provisions contained in the definition of “Interest Period” in Section 1.1 and paragraph (a) or (b) above, the Applicable Administrative Agent will forthwith so notify the Applicable Borrower and the applicable Lenders and (A) if denominated in Dollars under the US Facility, such affected Advances will be made available to the US Borrower on the date of such Borrowing as US Base Rate Advances or, if such affected Advances are existing Advances, will be Converted into US Base Rate Advances at the end of Interest Period then in effect, (B) if under the Canadian Facility, such affected Advances will be made available to the Canadian Borrower on the date of such Borrowing as Canadian Base Rate (US$) Advances or, if such affected Advances are existing Advances, will be Converted into Canadian Base Rate (US$) Advances at the end of Interest Period then in effect, and (C) if denominated in a Foreign Currency under the US Facility, the US Borrower shall be deemed to have specified an Interest Period of one month for such affected Advances or, if such affected Advances are existing Advances, such affected Advances will be continued as a Eurocurrency Advance in the original Designated Currency with an Interest Period of one month.

     (xiii) If the Canadian Borrower shall fail to select the duration or continuation of any Contract Period for any B/A Advance in accordance with the provisions contained in the definition of “Contract Period” in Section 1.1, clause (a) and (b) above, and Section 2.5, the Canadian Administrative Agent will forthwith so notify the Canadian Borrower and the Canadian Lenders and such affected B/A Advances will be made available to the Canadian Borrower on the date of such Borrowing as Canadian Base Rate (C$) Advances or, if such affected B/A Advances are existing Advances, will be automatically Converted into Canadian Base Rate (C$) Advances at the end of the Contract Period then in effect.

     (d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on the Applicable Borrower.

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

     (f) Funding by Lenders; Administrative Agents’ Reliance. Unless the Applicable Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing of Eurocurrency Advances or of B/A Advances, or prior to noon on the date of any Borrowing of Base Rate Advances, that such Lender will not make available to the Applicable Administrative Agent such Lender’s share of such Borrowing, the Applicable Administrative Agent may assume that such Lender has made such share available in accordance with and at the time required in Section 2.6 (or, in the case of a Borrowing of B/A Advances, that such Lender has made such share available in accordance with and at the time required by Section 2.5) and may, in reliance upon such assumption, make available to the Applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Applicable Administrative Agent, then the applicable Lender and the Applicable Borrower severally agree to pay to the Applicable Administrative Agent forthwith on demand such corresponding amount in Same Day Funds with interest thereon, for each day from and including the date such amount is made available to such Borrower to but excluding the date of payment to the Applicable Administrative Agent, at (A) in the case of a payment to be made by such Lender, the Overnight Rate and (B) in the case of a payment to be made by such Borrower, the interest rate applicable to the requested Borrowing. If such Borrower and such Lender shall pay such interest to the Applicable Administrative Agent for the same or an overlapping period, the Applicable Administrative Agent shall promptly remit to such Borrower the amount of such interest paid by such Borrower for such period. If such Lender pays its share of the applicable Borrowing to the Applicable Administrative Agent, then the amount so paid shall constitute such Lender’s Advance included in such Borrowing. Any payment by such Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Applicable Administrative Agent. A notice of the Applicable Administrative Agent to any Lender or Applicable Borrower with respect to any amount owing under this subsection (f) shall be conclusive, absent manifest error.

Section 2.7 Prepayments; Defeasance.

     (a) Right to Prepay. No Borrower shall have any right to prepay any principal amount of any Advance except as provided in this Section 2.7.

     (b) Optional.

     (ii) The Canadian Borrower may defease any B/A or B/A Equivalent Advance by depositing with the Canadian Administrative Agent an amount that, together with interest accruing on such amount to the end of the Contract Period for such B/A or B/A Equivalent Advance is sufficient to pay such maturing B/As or B/A Equivalent Advances when due.

     (iii) If any currency shall cease to be an Agreed Currency as provided herein, then promptly, but in any event within five (5) Business Days of receipt of the notice from the US Administrative Agent provided for in such sentence, the US Borrower shall prepay all US Advances funded and

denominated in such affected currency or Convert such US Advances into Advances in Dollars, subject to the other terms set forth in Article II.

     (iv) If a Commitment Increase is effected as permitted under Section 2.1(f), the US Borrower shall prepay any US Advances outstanding on such Increase Date and the Canadian Borrower shall prepay any Canadian Advances to the extent necessary to keep the outstanding Canadian Advances and the outstanding US Advances ratable to reflect the revised Applicable Percentages arising from such Commitment Increase. Any prepayment made by US Borrower in accordance with this clause (iv) may be made with the proceeds of Advances made by all the Lenders in connection the Commitment Increase occurring simultaneously with the prepayment.

     (v) If, at any time and for any reason, the US Outstandings on such date exceeds the aggregate US Commitments then in effect, then US Borrower shall immediately, first prepay outstanding US Advances, second prepay outstanding US Swingline Advances, and third make deposits into the US Cash Collateral Account, such that after giving effect to such prepayment or provision, the Dollar Equivalent of the US Outstandings does not exceed the aggregate US Commitments.

     (vi) If, at any time and for any reason, the Canadian Outstandings on such date exceeds the aggregate Canadian Commitments then in effect, then Canadian Borrower shall immediately, first prepay outstanding Canadian Advances, second prepay outstanding Canadian Swingline Advances, and third make deposits into the Canadian Cash Collateral Account, such that after giving effect to such prepayment or provision, the Dollar Equivalent of the Canadian Outstandings does not exceed the aggregate Canadian Commitments.

     (vii) If, at any time and for any reason, the US Outstandings on such date exceeds the Credit Amount then in effect for the US Facility (such excess being a “Deficiency”), then US Borrower shall immediately, first prepay outstanding US Advances, second prepay outstanding US Swingline Advances, and third make deposits into the US Cash Collateral Account, such that after giving effect to such prepayment or provision, the Dollar Equivalent of the US Outstandings does not exceed such Credit Amount; provided, however, that in the case of a Deficiency caused solely as a result of the charging by US Administrative Agent of Lender Group Expenses to the Loan Account and so long as such Deficiency is not in excess of the aggregate US Commitments, the US Borrower shall have 3 Business Days from the date of the initial occurrence of such charge to pay to US Administrative Agent, in cash, the amount of such excess (which period of 3 Business Days shall in no event be duplicative of the 3 Business Days period referenced in Section 7.1(a) of this Agreement).

     (d) Interest; Costs. Each prepayment pursuant to this Section 2.7 shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.12 as a result of such prepayment being made on such date.

Section 2.11 Illegality. If any Lender shall notify a Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other governmental authority asserts that it is unlawful, for such Lender or its Lending Office to perform its obligations under this Agreement to make, maintain, or fund any Eurocurrency Advances or B/A Advances of such Lender then outstanding hereunder, (a) the Applicable Borrower shall, no later than 11:00 a.m. (Houston, Texas, time or Calgary, Alberta Canada time, as applicable) (i) if not prohibited by

Section 2.13 Increased Costs.

     (a) Increased Costs Generally. If any Change in Law shall:

     (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement contemplated by Section 2.13(e)), any Issuing Lender or any Underlying Issuer;

     (ii) subject any Lender, any Underlying Issuer or any Issuing Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit, any Eurocurrency Advance made by it, or any B/A Advance made or accepted and purchased by it, or change the basis of taxation of payments to such Lender, Underlying Issuer or Issuing Lender in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 2.15 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender, Underlying Issuer or Issuing Lender); or

     (iii) impose on any Lender, Underlying Issuer or Issuing Lender or the London interbank market any other condition, cost or expense affecting this Agreement or Eurocurrency Advances made by such Lender or B/A Advances made or accepted and purchased 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 Eurocurrency Advance or accepting and purchasing any B/A Advance (or of maintaining its obligation to make or accept and purchase any such Advance), or to increase the cost to such Lender, Underlying Issuer or Issuing Lender of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, Underlying Issuer or Issuing Lender hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Underlying Issuer or Issuing Lender, the US Borrower will pay to such US Lender, Underlying Issuer or US Issuing Lender, and the Canadian Borrower will pay to such Canadian Lender or Canadian Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender, Underlying Issuer or Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered.

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

     (c) Certificates for Reimbursement. A certificate of a Lender, Underlying Issuer or Issuing Lender (together with such further information as the Borrowers may reasonably request) setting forth the amount or amounts necessary to compensate such Lender, Underlying Issuer or Issuing Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section and delivered to the Applicable Borrower shall be conclusive absent manifest error. The Applicable Borrower shall pay such Lender, Underlying Issuer or Issuing Lender, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

     (d) Delay in Requests. Failure or delay on the part of any Lender, Underlying Issuer or Issuing Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s, Underlying Issuer’s or such Issuing Lender’s right to demand such compensation, provided that the Borrowers shall not be required to compensate a Lender, Underlying Issuer or Issuing Lender pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender, Underlying Issuer or Issuing Lender, as the case may be, notifies the Applicable Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s, Underlying Issuer’s or Issuing Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

     (e) Additional Reserve Requirement. The Applicable Borrower (subject to the proviso set forth below) shall pay to each Lender Party, (i) as long as such Lender Party shall be required to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency funds or deposits (currently known as Eurocurrency Liabilities), additional interest on the unpaid principal amount of each Eurocurrency Advance equal to the actual costs of such reserves allocated to such Advance by such Lender Party (as determined by such Lender Party in good faith, which determination shall be conclusive in the absence of manifest error), and (ii) as long as such Lender Party shall be required to comply with any reserve ratio requirement or analogous requirement of any other central banking or financial regulatory authority imposed in respect of the maintenance of the US Commitments or the Canadian Commitments or the funding of the Eurocurrency Advances, such additional costs (expressed as a percentage per annum and rounded upwards, if necessary, to the nearest five decimal places) equal to the actual costs allocated to such US Commitments, Canadian Commitment or Advance by such Lender Party (as determined by such Lender Party in good faith, which determination shall be conclusive in the absence of manifest error), which in each case, shall be due and payable on each date on which interest is payable on such Advance; provided that, the Applicable Borrower shall have received at least 3 Business Days’ prior notice (with a copy to each Administrative Agent) of such additional interest or costs from such Lender Party. If a Lender Party fails to give notice 3 Business Days prior to the relevant payment date for interest, such additional interest or costs shall be due and payable 3 Business Days from receipt of such notice.

Section 2.14 Payments and Computations.

     (a) Payments. All payments to be made by the Borrowers shall be made without condition or deduction for any counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein and except with respect to principal of and interest on Advances denominated in a Foreign Currency and Letter of Credit Obligations on Letters of Credit denominated in a Foreign Currency, all payments by the Borrowers hereunder shall be made to the Applicable Administrative Agent, for the account of the respective Lenders to which such payment is owed in Dollars and in Same Day Funds. Except as otherwise expressly provided herein, all payments by the Borrowers hereunder with respect to principal and interest on Advances denominated in a Foreign Currency and Letter of Credit Obligations on Letters of Credit denominated in a Foreign Currency shall be made to the Applicable Administrative Agent, for the account of the respective Lenders to which such payment is owed, in such Foreign Currency and in Same Day Funds. If, for any reason, any Borrower is prohibited by any Legal Requirement from making any required payment hereunder in a Foreign Currency, such Borrower shall make such payment in Dollars in the Dollar Equivalent of the Foreign Currency payment amount. Subject to Section 2.6(c), each payment of any Advance pursuant to this Section or any other provision of this Agreement shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

     (b) Payments by Borrowers; Presumptions by Administrative Agents. Unless the Applicable Administrative Agent shall have received notice from the Applicable Borrower prior to the date on which any payment is due to the Applicable Administrative Agent for the account of the applicable Lenders or the Applicable Issuing Lenders hereunder that the Applicable Borrower will not make such payment, the Applicable Administrative Agent may assume that the Applicable Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Applicable Issuing Lenders, as the case may be, the amount due. In such event, if the Applicable Borrower has not in fact made such payment, then each of the applicable Lenders or the Applicable Issuing Lenders, as the case may be, severally agrees to repay to the Applicable Administrative Agent forthwith on demand the amount so distributed to such Lender or Applicable Issuing Lender, in Same Day Funds 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 Applicable Administrative Agent, at the Overnight Rate. A notice of the Applicable Administrative Agent to any Lender or Applicable Borrower with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

     (c) Payment Procedures. The Borrowers shall make each payment of any amount under this Agreement and under any other Credit Document not later than 11:00 a.m. (Houston, Texas time or Calgary, Alberta Canada time, as applicable) on the day when due to the Applicable Administrative Agent at the Applicable Administrative Agent’s (or such other location as the Applicable Administrative Agent shall designate in writing to the Applicable Borrower) in Same Day Funds. Without limiting the generality of the foregoing, the US Administrative Agent may require that any payments due under this Agreement under the US Facility be made in the United States and the Canadian Administrative agent may require that any payments due under this Agreement under the Canadian Facilities be made in Canada. The Applicable Administrative Agent will promptly thereafter, and in any event prior to the close of business on the day any timely payment is made, cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to any specific Lender Party pursuant to Sections 2.4, 2.11, 2.12, 2.13, 2.15, and 9.1 but after taking into account payments effected pursuant to Section 2.15) in accordance with each Lender’s Applicable Percentage to the Lenders for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon receipt of other amounts due solely to the US Administrative Agent, US Issuing Lender, Underlying Issuer, US Swingline Lender, Canadian Administrative Agent, Canadian Issuing Lender, Canadian Swingline Lender, or a specific Lender, the Applicable Administrative Agent shall distribute such amounts to the appropriate party to be applied in accordance with the terms of this Agreement.

     (d) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of Eurocurrency Advances or B/A Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

     (e) Computations. All computations of interest and fees shall be made by the Applicable Administrative Agent on the basis of a year of 365/366 days for Base Rate Advances based on the Adjusted Base Rate (other than based on the 3-Month LIBOR) or the Canadian Base Rate, and a year of 360 days for all other interest and fees, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Applicable Administrative Agent of an amount of interest or fees shall be conclusive and binding for all purposes, absent manifest error. For purposes of the Interest Act (Canada) and disclosure thereunder, the annual rates of interest to which the rates determined in accordance with the

provisions hereof on the basis of a period of calculation less than a year are equivalent, are the rates so determined (a) multiplied by the actual number of days in the one year period beginning on the first day of the period of calculation, and (b) divided by the number of days in the period of calculation. The principle of deemed reinvestment of interest shall not apply to any interest calculation under this Agreement; all interest payments to be made hereunder shall be paid without allowance or deduction for deemed reinvestment or otherwise. The rates of interest specified in this Agreement are intended to be nominal rates and not effective rates. Interest calculated hereunder shall be calculated using the nominal rate method and not the effective rate method of calculation.

     (f) Sharing of Payments, Etc.

     (i) Each Canadian Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim against a Borrower or any other Credit Party, or pursuant to a secured claim or other security or interest arising from, or in lieu of, such secured claim, received by such Canadian Lender under any applicable Debtor Relief Law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any Canadian Advance or the participations in the Canadian Letter of Credit Obligations or in the Canadian Swingline Advances held by it, as a result of which the unpaid portion of its Canadian Advances shall be proportionately less than the unpaid portion of the Canadian Advances or the participations in the Canadian Letter of Credit Obligations or in the Canadian Swingline Advances held by it of any other Canadian Lender, it shall be deemed simultaneously to have purchased from such other Canadian Lender at face value, and shall promptly pay to such other Canadian Lender the purchase price for, a participation in the Canadian Advances, the participations in the Canadian Letter of Credit Obligations and in the Canadian Swingline Advances held by it of such other Canadian Lender, so that the aggregate unpaid amount of the Canadian Advances and participations in Canadian Advances, Canadian Letter of Credit Obligations and Canadian Swingline Advances held by each Canadian Lender shall be in the same proportion to the aggregate unpaid amount of all Canadian Advances, Canadian Letter of Credit Obligations and Canadian Swingline Advances then outstanding as the amount of its Canadian Advances, and participations in Canadian Letter of Credit Obligations and Canadian Swingline Advances prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the amount of all Canadian Advances and participations in Canadian Letter of Credit Obligations and Canadian Swingline Advances, outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that if any such purchase or purchases or adjustments shall be made pursuant to this Section 2.14(f)(i) and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest.

     (ii) Each US Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim against a Borrower or any other Credit Party, or pursuant to a secured claim or other security or interest arising from, or in lieu of, such secured claim, received by such US Lender under any applicable Debtor Relief Law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any US Advance or the participations in the US Letter of Credit Obligations or in the US Swingline Advances held by it, as a result of which the unpaid portion of its US Advances shall be proportionately less than the unpaid portion of the US Advances or the participations in the US Letter of Credit Obligations or in the US Swingline Advances held by it of any other US Lender, it shall be deemed simultaneously to have purchased from such other US Lender at face value, and shall promptly pay to such other US Lender the purchase price for, a participation in the US Advances, the participations in the US Letter of Credit Obligations and in the US Swingline Advances held by it of such other US Lender, so that the aggregate unpaid amount of the US Advances and participations in US Advances, US Letter of Credit Obligations and US Swingline Advances held by each US Lender shall be in the same proportion to the aggregate unpaid

amount of all US Advances, US Letter of Credit Obligations and US Swingline Advances then outstanding as the amount of its US Advances, and participations in US Letter of Credit Obligations and US Swingline Advances prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the amount of all US Advances and participations in US Letter of Credit Obligations and US Swingline Advances, outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that if any such purchase or purchases or adjustments shall be made pursuant to this Section 2.14(f)(ii) and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest.

Each 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 such Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

Section 2.15 Taxes. Any and all payments by or on account of any obligation of the respective Borrowers hereunder or under any other Credit Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if the Applicable Borrower shall be required by applicable law to deduct any Indemnified Taxes (including any 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 applicable Administrative Agent, Lender, Underlying Issuer or Issuing Lender, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

     (a) Payment of Other Taxes by the Borrowers. Without limiting the provisions of the terms set forth in this Section above, each Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

     (b) Indemnification by the Borrowers. The Canadian Borrower shall, and does hereby, indemnify the Canadian Administrative Agent, each Canadian Lender and the Canadian Issuing Lender, and the US Borrower shall, and does hereby, indemnify the US Administrative Agent, each US Lender, each Underlying Issuer and the US Issuing Lender, in any case, within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the such Administrative Agent, such Lender, such Underlying Issuer or such Issuing Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, except as a result of the gross negligence or willful misconduct of such Administrative Agent, such Lender, such Underlying Issuer or such Issuing Lender, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to a Borrower by a Lender, Underlying Issuer or an Issuing Lender (with a copy to the Applicable Administrative Agent), or by the Applicable Administrative Agent on its own behalf or on behalf of a Lender, Underlying Issuer or an Issuing Lender, shall be conclusive absent manifest error.

     (c) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Borrower to a Governmental Authority, such Borrower shall deliver to the Applicable Administrative Agent the original or a certified copy of any available receipt issued by such

Governmental Authority evidencing such payment, a copy of the return (if any) reporting such payment or other evidence of such payment.

     (d) Status of Lenders.

     (i) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which a Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Credit Document shall deliver to the Applicable Borrower (with a copy to the Applicable Administrative Agent), prior to the Effective Date (or upon becoming a Lender by assignment or participation) and at any time or times prescribed by applicable law or reasonably requested by the Applicable Borrower or the Applicable Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Applicable Borrower or the Applicable Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Applicable Borrower or the Applicable Administrative Agent as will enable such Borrower or such Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

     (ii) Without limiting the generality of the foregoing, in the event that a Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to the US Borrower and the US Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the US Borrower or the US Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

     (A) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party,

     (B) duly completed copies of Internal Revenue Service Form W-8ECI,

     (C) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Applicable Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

     (D) Any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit the Company to determine the withholding or deduction required to be made.

     (iii) Without limiting the obligations of the Lenders set forth above regarding delivery of certain forms and documents to establish each Lender’s status for U.S. withholding tax purposes, each Lender agrees promptly to deliver to the Applicable Administrative Agent or the Applicable Borrower, as the Applicable Administrative Agent or the Applicable Borrower shall reasonably request, on or prior to the Effective Date, and in a timely fashion thereafter, such other documents and forms required by any relevant taxing authorities under any Legal Requirement of any other

jurisdiction, duly executed and completed by such Lender, as are required under such Legal Requirements to confirm such Lender’s entitlement to any available exemption from, or reduction of, applicable withholding taxes in respect of all payments to be made to such Lender outside of the U.S. by the Borrowers pursuant to this Agreement or otherwise to establish such Lender’s status for withholding tax purposes in such other jurisdiction.

     (iv) Each Lender shall promptly (i) notify the Applicable Administrative Agent of any change in circumstances which would modify or render invalid any such claimed exemption or reduction, and (ii) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Lender, and as may be reasonably necessary (including the re-designation of its Lending Office) to avoid any requirement of applicable Legal Requirements of any such jurisdiction that any Borrower make any deduction or withholding for taxes from amounts payable to such Lender.

     (e) Treatment of Certain Refunds. If any Lender Party determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by any Borrower or with respect to which any Borrower has paid additional amounts pursuant to this Section, it shall pay to such Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Administrative Agent, such Lender or such Issuing Lender, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that each Borrower, upon the request of such Administrative Agent, such Lender, such Underlying Issuer or such Issuing Lender, agrees to repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Administrative Agent, such Lender, such Underlying Issuer or such Issuing Lender in the event such Administrative Agent, such Lender or such Issuing Lender is required to repay such refund to such Governmental Authority. This subsection shall not be construed to require any Lender Party to make available its tax returns (or any other information relating to its taxes that it deems confidential) to any Borrower or any other Person.

     (f) Special Provisions with respect to Canadian Lenders. Notwithstanding anything herein to the contrary, so long as no Default exists, each Canadian Lender, the Canadian Administrative Agent, the Canadian Issuing Lender and Canadian Swingline Lender (each a “Canadian Lender Party”) shall be a resident of Canada for the purposes of the ITA in that it shall either be incorporated under the laws of Canada or a province thereof or be an “authorized foreign bank” as defined under the ITA that will receive all amounts paid or credited to it with respect to the Canadian Facilities in respect of its “Canadian banking business” for the purposes of the ITA (a “Canadian Resident Lender”). In the event that a Canadian Lender Party does not qualify as a Canadian Resident Lender, the Canadian Lender Party shall deliver to the Canadian Borrower and the Canadian Administrative Agent on the date on which such Canadian Lender Party becomes a Canadian Lender Party hereunder or otherwise does not qualify as a Canadian Resident Lender, notice that it is not a Canadian Resident Lender. It is acknowledged that there may be Canadian tax imposed under Part XIII of the ITA (“Canadian Withholding Tax”) on any payments as, on account or in lieu of payment of, or in satisfaction of, interest and other fees paid by the Canadian Borrower with respect to the Canadian Facilities to persons who are not Canadian Resident Lenders (such payments a “Taxable Payment”). So long as no Default exists, the Canadian Borrower and the Canadian Administrative Agent shall have no obligation to make any additional or increased payment under this Agreement in respect of any Canadian Withholding Tax on a Taxable Payment, and the Canadian Borrower shall be entitled to deduct and remit to the proper Canadian taxing authorities any Canadian Withholding Tax on any Taxable Payment. For greater certainty, so long as no Default exists, Indemnified Taxes and Other Taxes in this Section 2.15 shall not include any Canadian Withholding Taxes.

Section 2.16 Replacement of Lenders. Mitigation Obligations; Replacement of Lenders.

     (a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.13, or requires a Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, or suspends its obligation to continue, or Convert Advances into, Eurocurrency Advances pursuant to Section 2.6(c)(vi) or Section 2.11, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Credit Extensions hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or 2.15, as the case may be, in the future or if applicable, would avoid the effect of Section 2.6(c)(vi) or Section 2.11, (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Each Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

     (b) Replacement of Lenders. If (i) any Lender requests compensation under Section 2.13, (ii) a Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, (iii) any Lender suspends its obligation to continue, or Convert Advances into, Eurocurrency Advances pursuant to Section 2.6(c)(vi) or Section 2.11, (iv) any Lender is then a Defaulting Lender or a Potential Defaulting Lender, or (v) any Lender (a “Non-Consenting Lender”) refuses to consent to an amendment, modification or waiver of this Agreement that requires consent of 100% of the Lenders pursuant to Section 9.2(c), consent of 100% of the US Lenders pursuant to Section 9.2(a) or 100% of the Canadian Lenders pursuant to Section 9.2(b) (any such Lender, a “Subject Lender”), then the Applicable Borrower may as to any Subject Lender, at its sole expense and effort, and the Applicable Administrative Agent may as to any Non-Consenting Lender (but neither shall be obligated to), upon notice to the Subject Lender, the Borrowers (if requested by the Applicable Administrative Agent), and the Applicable Administrative Agent (if requested by the Borrowers), require such Subject Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.6), all of its interests, rights and obligations under this Agreement and the related Credit Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment), provided that:

(A) the Applicable Borrower shall have paid to the Applicable Administrative Agent the assignment fee specified in Section 9.6;

(B) such Subject Lender shall have received payment of an amount equal to the outstanding principal of its Advances and participations in outstanding Letter of Credit Obligations and funded participations in outstanding Swingline Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents (including any amounts under Section 2.12) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Applicable Borrower (in the case of all other amounts);

(C) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments thereafter;

(D) in the event such Subject Lender is a Non-Consenting Lender, each assignee shall consent, at the time of such assignment, to each matter in respect of which such Subject Lender was a Non-Consenting Lender; and

(E) such assignment does not conflict with applicable Legal Requirements.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Applicable Borrower to require such assignment and delegation cease to apply.

Section 2.17 Settlement. It is agreed that each US Lender’s funded portion of the US Advances and US Swingline Advances is intended by the US Lenders to equal, at all times, such US Lender’s Applicable Percentage of the outstanding US Advances and US Swingline Advances. Such agreement notwithstanding, US Administrative Agent, US Swingline Lender, and the other US Lenders agree (which agreement shall not be for the benefit of either Borrower or any other Credit Party) that in order to facilitate the administration of this Agreement and the other Credit Documents, settlement among the US Lenders as to the US Advances and the US Swingline Advances shall take place on a periodic basis in accordance with the following provisions:

     (a) US Administrative Agent shall request settlement (“Settlement”) with the US Lenders on a weekly basis, or on a more frequent basis if so determined by US Administrative Agent (1) on behalf of US Swingline Lender, with respect to the outstanding US Swingline Advances, (2) for itself, with respect to the outstanding Overadvances, and (3) with respect to the US Borrower’s or its Subsidiaries’ payments received, as to each by notifying the US Lenders by telecopy, telephone, or other similar form of transmission, of such requested Settlement, no later than 3:00 p.m. (Houston, Texas time) / 4:00 p.m. (Atlanta, Georgia time) on the Business Day immediately prior to the date of such requested Settlement (the date of such requested Settlement being the “Settlement Date”). Such notice of a Settlement Date shall include a summary statement of the amount of outstanding US Advances and US Swingline Advances for the period since the prior Settlement Date. Subject to the terms and conditions contained: (y) if a US Lender’s balance of the US Advances or US Swingline Advances exceeds such US Lender’s Applicable Percentage of such Advances as of a Settlement Date, then US Administrative Agent shall, by no later than 1:00 p.m. (Houston, Texas time) / 3:00 p.m. (Atlanta, Georgia time) on the Settlement Date, transfer in immediately available funds to a deposit account of such US Lender (as such US Lender may designate), an amount such that each such US Lender shall, upon receipt of such amount, have as of the Settlement Date, its Applicable Percentage of such Advances, and (z) if a US Lender’s balance of the US Advances or US Swingline Advances is less than such US Lender’s Applicable Percentage of such Advances as of a Settlement Date, such US Lender shall no later than 1:00 p.m. (Houston, Texas time) / 3:00 p.m. (Atlanta, Georgia time) on the Settlement Date transfer in immediately available funds to US Administrative Agent’s Account, an amount such that each such US Lender shall, upon transfer of such amount, have as of the Settlement Date, its Applicable Percentage of such Advances. Such amounts made available to US Administrative Agent under clause (z) of the immediately preceding sentence shall be applied against the amounts of the applicable US Swingline Advances and, together with the portion of such US Swingline Advances representing US Swingline Lender’s Applicable Percentage thereof, shall constitute US Advances of such US Lenders. If any such amount is not made available to US Administrative Agent by any US Lender on the Settlement Date applicable thereto to the extent required by the terms hereof, US Administrative Agent shall be entitled to recover for its account such amount on demand from such US Lender together with interest thereon at the Overnight Rate.

     (b) In determining whether a US Lender’s balance of the US Advances or US Swingline Advances is less than, equal to, or greater than such Lender’s Applicable Share of the US Advances or US Swingline Advances as of a Settlement Date, US Administrative Agent shall, as part of the relevant Settlement, apply to such balance the portion of payments actually received in good funds by US Administrative Agent with respect to principal, interest, fees payable by US Borrower and allocable to the US Lenders hereunder, and proceeds of Collateral.

Section 2.18 Method of Payment. US Borrower hereby authorizes US Administrative Agent and the US Swingline Lender, from time to time without prior notice to US Borrower, to charge all interest, letter

of credit fees, and all other fees payable hereunder or under any of the other Credit Documents (in each case, as and when due and payable), all costs, expenses, and Lender Group Expenses payable hereunder or under any of the other Credit Documents (in each case, as and when incurred), all charges, commissions, fees, and costs provided for in Section 2.3(l)(iii) (as and when accrued or incurred), and all other payments as and when due and payable under any Credit Document (including any amounts due and payable to Swap Counterparties in respect of Hedging Arrangements up to the amount of the Swap Reserve) to the Loan Account, which amounts thereafter shall constitute US Advances hereunder and shall accrue interest at the rate then applicable to US Base Rate Advances. Any interest, fees, costs, expenses, Lender Group Expenses, or other amounts payable hereunder or under any other Credit Document not paid when due shall be compounded by being charged to the Loan Account and shall thereafter constitute US Advances hereunder and shall accrue interest at the rate then applicable to US Base Rate Advances (unless and until converted into Eurocurrency Advances in accordance with the terms of this Agreement).

Section 2.19 Crediting Payments. The receipt of any payment item by US Administrative Agent shall not be considered a payment on account unless such payment item is a wire transfer of immediately available federal funds made to US Administrative Agent’s Account or unless and until such payment item is honored when presented for payment. Should any payment item not be honored when presented for payment, then US Borrower shall be deemed not to have made such payment and interest shall be calculated accordingly. Anything to the contrary contained herein notwithstanding, any payment item shall be deemed received by US Administrative Agent only if it is received into US Administrative Agent ‘s Account on a Business Day on or before 11:00 a.m. (Houston, Texas time) / 12:00 noon (Atlanta, Georgia time). If any payment item is received into US Administrative Agent ‘s Account on a non-Business Day or after 11:00 a.m. (Houston, Texas time) / 12:00 noon (Atlanta, Georgia time) on a Business Day, it shall be deemed to have been received by US Administrative Agent as of the opening of business on the immediately following Business Day.

Section 2.20 Designated Account. US Administrative Agent is authorized to make the US Advances, and US Issuing Lender and the Underlying Issuers are authorized to issue the Letters of Credit, under this Agreement based upon telephonic or other instructions received from anyone purporting to be a Responsible Officer or, without instructions, if pursuant to Section 2.18. US Borrower agrees to establish and maintain the Designated Account with the depositary bank thereof for the purpose of receiving the proceeds of the US Advances requested by US Borrower and made by US Administrative Agent or the US Lenders hereunder. Unless otherwise agreed by US Administrative Agent and US Borrower, any US Advance or US Swingline Advance requested by US Borrower and made by US Administrative Agent or the US Lenders hereunder shall be made to the Designated Account.

Section 2.21 Maintenance of Loan Account; Statements of Obligations. US Administrative Agent shall maintain an account on its books in the name of US Borrower (the “Loan Account”) on which US Borrower will be charged with all US Advances made by US Administrative Agent, US Swingline Lender, or the US Lenders to US Borrower or for US Borrower’s account, the Letters of Credit issued or made by US Issuing Lender hereunder, and with all other payment Obligations hereunder or under the other Credit Documents (except for Obligations arising under Hedging Arrangements and payments with respect to the Canadian Facility), including, accrued interest, fees and expenses, and Lender Group Expenses. In accordance with Section 2.19, the Loan Account will be credited with all payments received by US Administrative Agent from US Borrower or for US Borrower’s account. US Administrative Agent shall render monthly statements regarding the Loan Account to US Borrower, including principal, interest, fees, and including an itemization of all charges and expenses constituting Lender Group Expenses owing, and such statements, absent manifest error, shall be conclusively presumed to be correct and accurate and constitute an account stated between US Borrower and the US Secured Parties unless,

within 60 days after receipt thereof by US Borrower, US Borrower shall deliver to US Administrative Agent written objection thereto describing the error or errors contained in any such statements.

Section 2.22 Optional Overadvances.

     (a) Any contrary provision of this Agreement notwithstanding but subject to Article III, the US Lenders hereby authorize US Administrative Agent or US Swingline Lender, as applicable, and US Administrative Agent or US Swingline Lender, as applicable, may, but is not obligated to, knowingly and intentionally, continue to make US Advances (including US Swingline Advances) to the US Borrower (any of the Advances described in this Section 2.22(a) shall be referred to as “Overadvances”) so long as (i) after giving effect to such Overadvances, the aggregate US Outstandings does not exceed the US Borrowing Base by more than $11,250,000, (ii) after giving effect to such Overadvances, the aggregate US Outstandings does not exceed the aggregate US Commitments and (iii) all Overadvances must be repaid in full within 30 days following each initial Overadvance and no Overadvance shall be in existence for at least 10 days therafter. Each party hereto hereby acknowledge and agree that any charges to the Loan Account of interest, fees, or Lender Group Expenses shall constitute Overadvances to the extent such amount, if counted as a US Advance, would cause the aggregate US Outstandings to exceed the US Borrowing Base by more than $11,250,000; provided that, in no event shall the aggregate US Outstandings exceed the aggregate US Commitments.

     (b) Each Overadvance shall be deemed to be a US Advance hereunder, except that no Overadvance shall be eligible to be a Eurocurrency Advance. The Overadvances shall be repayable on demand, secured by the US Administrative Agent’s Liens granted pursuant to the Credit Documents, constitute Obligations hereunder, and bear interest at the rate applicable from time to time to Advances that are US Base Rate Advances. The provisions of this Section 2.22 are for the exclusive benefit of US Administrative Agent, US Swingline Lender, and the US Lenders and are not intended to benefit either Borrower or any other Credit Party in any way.

     (c) Notwithstanding anything contained in this Agreement or any other Credit Document to the contrary, no Overadvance may be made by US Administrative Agent if such Advance would cause the aggregate US Outstandings to exceed the US Commitments in effect at such time.

Section 4.8 Compliance with Agreements.

     (a) Neither Borrower nor any Subsidiary is a party to any indenture, loan or credit agreement or any lease or any other types of agreement or instrument or subject to any charter or corporate restriction or provision of applicable law or governmental regulation the performance of or compliance with which could reasonably be expected to cause a Material Adverse Change. Neither Borrower nor any Subsidiary is in default under or with respect to any contract, agreement, lease or any other types of agreement or instrument to which such Borrower or such Subsidiary is a party and which could reasonably be expected to cause a Material Adverse Change.

     (b) No Default has occurred and is continuing. Additionally, no event of default under any financing agreement which would constitute an Event of Default under Section 7.1(f) has occurred and is continuing.

Section 4.9 Pension Plans. (a) Except for matters that could not reasonably be expected to result in a Material Adverse Change, all Plans are in compliance in all material respects with all applicable provisions of ERISA, (b) no Termination Event has occurred with respect to any Plan that would result in an Event of Default under Section 7.1(i), and, except for matters that could not reasonably be expected to result in a Material Adverse Change, each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code, (c) no “accumulated funding deficiency” (as defined in Section 302 of ERISA) has occurred with respect to any Plan and there has been no excise tax imposed upon any Borrower or any Subsidiary under Section 4971 of the Code, (d) to the knowledge of each Borrower, except for matters that could not reasonably be expected to result in a Material Adverse Change, no Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in accordance with applicable provisions of ERISA and the Code, (e) the present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits in an amount that could reasonably be expected to result in a Material Adverse Change, (f) neither Borrower nor any member of

the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for which there is any unsatisfied withdrawal liability that could reasonably be expected to result in a Material Adverse Change or an Event of Default under Section 7.1(j), and (g) except for matters that could not reasonably result in a Material Adverse Change, as of the most recent valuation date applicable thereto, neither Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if any Borrower or any Subsidiary has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, neither Borrower has any reason to believe that the annual cost during the term of this Agreement to any Borrower or any Subsidiary for post-retirement benefits to be provided to the current and former employees of any Borrower or any Subsidiary under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change.

     (c) Certain Actions.

Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Company or any Subsidiary or other Affiliate thereof as if such Person were not the US Administrative Agent or the Canadian Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 8.3 Exculpatory Provisions. Neither Administrative Agent shall have any duties or obligations except those expressly set forth herein and in the other Credit Documents. Without limiting the generality of the foregoing, neither Administrative Agent:

Neither Administrative Agent shall be liable for any action taken or not taken by it (i) with the consent or at the request of the US Majority Lenders or Canadian Majority Lenders, as applicable (or such other number or percentage of the Lenders as shall be necessary, or as such Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 9.2 and 7.1) or (ii) in the absence of its own gross negligence or willful misconduct.

Upon receipt of any such notice of resignation, (a) the US Majority Lenders shall have the right, in consultation with the US Borrower, to appoint a successor US Administrative Agent, US Issuing Lender and US Swingline Lender which need not all be one Person but which, in each case, shall be a bank with an office in Houston, Texas or an Affiliate of any such bank with an office in Houston, Texas, and (b) the Canadian Majority Lenders shall have the right, in consultation with the Canadian Borrower, to appoint a successor Canadian Administrative Agent, Canadian Issuing Lender, and Canadian Swingline Lender which need not all be one Person but which, in each case, shall be a bank who is a Canadian Resident Lender with an office in Calgary, Alberta Canada, or an Affiliate of any such bank with an office in Calgary, Alberta Canada. If no such successor shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Administrative Agent or Issuing Lender gives notice of its resignation, then the retiring Administrative Agent or Issuing Lender, as applicable, may on behalf of the Lenders and Issuing Lenders, appoint a successor agent or issuing lender meeting the qualifications set forth above provided that if the retiring Administrative Agent or Issuing Lender shall notify the Borrowers and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent or Issuing Lender, as applicable, shall be discharged from its duties and obligations hereunder and under the other Credit Documents (except that (y) in the case of any collateral security held by such Administrative Agent on behalf of the Lenders or an Issuing Lender under any of the Credit Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed and (z) the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit.), and (2) all payments, communications and determinations provided to be made by, to or through the retiring Administrative Agent or Issuing Lender, as applicable, shall instead be made by or to each applicable class of Lenders, until such time as the applicable Majority Lenders appoint a successor Administrative Agent or Issuing Lender as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Administrative Agent or Issuing Lender hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges

and duties of the retiring (or retired) Administrative Agent or Issuing Lender, as applicable, and the retiring Administrative Agent or Issuing Lender, as applicable, shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrowers to a successor Administrative Agent or Issuing Lender, as applicable shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor.

Section 8.7 Non-Reliance on Administrative Agent and Other Lenders. Each Lender Party acknowledges that it has, independently and without reliance upon any Administrative Agent or any other Lender Party or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender Party also acknowledges that it will, independently and without reliance upon any Administrative Agent or any other Lender Party or any of their Related Parties 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 Credit Document or any related agreement or any document furnished hereunder or thereunder.

A copy of such intercreditor agreement will be made available to each Secured Party on the Effective Date and thereafter upon request.

Should any Lender or any Swap Counterparty obtain possession or control of any such Collateral, such Lender or Swap Counterparty shall notify the Applicable Administrative Agent thereof, and, promptly upon Applicable Administrative Agent’s request therefor shall deliver possession or control of such Collateral to Applicable Administrative Agent or in accordance with Applicable Administrative Agent’s instructions or otherwise take such actions as the Applicable Administrative Agent shall request to evidence and perfect such Administrative Agent’s Lien on such Collateral.

In case one or more provisions of this Agreement or the other Credit Documents shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality, and enforceability of the remaining provisions contained herein or therein shall not be affected or impaired thereby.

Section 9.4 Survival of Representations and Obligations. All representations and warranties contained in this Agreement or made in writing by or on behalf of any Borrower in connection herewith shall survive the execution and delivery of this Agreement and the other Credit Documents, the making Credit Extensions and any investigation made by or on behalf of the Lenders, none of which investigations shall diminish any Lender’s right to rely on such representations and warranties. All obligations of any Borrower provided for in Sections 2.12, 2.13, 2.15(b), and 9.1(a), (b) and (d) and all of the obligations of the Lenders in Section 9.1(c) shall survive any termination of this Agreement, repayment in full of the Obligations, and termination or expiration of all Letters of Credit.

Section 9.5 Successors and Assigns Generally. 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, except that neither Borrower may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender Party and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (a) to an Eligible Assignee in accordance with the provisions of Section 9.6(a), (b) by way of participation in accordance with the provisions of Section 9.6(d) or (c) by way of pledge or assignment of a security interest subject to the restrictions of Section 9.6(e) (and any other attempted assignment or transfer by any party hereto 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, Participants to the extent provided in Section 9.6(c) and, to the extent expressly contemplated hereby, the Related Parties of each Administrative Agent and each Lender) any legal or equitable right, remedy or claim under or by reason of this Agreement.

Section 9.6 Lender Assignments and Participations.

     (a) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Advances at the time owing to it); provided that

     (i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s applicable Commitment and the Advances under such Commitment at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Advances outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Advances of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Applicable Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $3,000,000 in the case of any assignment in respect the Facilities, unless the Applicable Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrowers otherwise consent (each such consent not to be unreasonably withheld or delayed); provided, however, that concurrent assignments to members of an Assignee Group and concurrent assignments from members of an Assignee Group to a single Eligible Assignee (or to an Eligible Assignee and members of its Assignee Group) will be treated as a single assignment for purposes of determining whether such minimum amount has been met;

     (ii) 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 with respect to the applicable Class of Advances or the applicable Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Facilities on a non-pro rata basis;

     (iii) any assignment of a Commitment must be approved by the Applicable Administrative Agent and the Applicable Issuing Lender (other than Underlying Issuers) unless the Person that is the proposed assignee is itself a Lender with a Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee);

     (iv) the parties to each assignment shall execute and deliver to the Applicable Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $2,000 (it being understood that only one such processing fee is payable for the series of concurrent assignments to members of an Assignee Group or the series of concurrent assignments from members of an Assignee Group to a single Eligible Assignee or to an Eligible Assignee and members of its Assignee Group) and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Applicable Administrative Agent an Administrative Questionnaire; and

     (v) copies of any Assignment and Assumption received by the Canadian Administrative Agent shall be promptly forwarded to the US Administrative Agent.

Subject to acceptance and recording thereof by the Applicable Administrative Agent pursuant to paragraph (b) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this

Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.12, 2.13, 2.15(b), 9.1(a), 9.1(b), 9.1(c), and 9.1(d) with respect to facts and circumstances occurring prior to the effective date of such assignment. 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 (c) of this Section.

     (b) Register. The US Administrative Agent, acting solely for this purpose as an agent of the US Borrower, shall maintain at one of its offices in Denver, Colorado or Houston, Texas a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the US Lenders and the US Commitments of, and principal amounts of the US Advances owing to, each US Lender pursuant to the terms hereof from time to time (the “US Register”). The Canadian Administrative Agent, acting solely for this purpose as an agent of the Canadian Borrower, shall maintain at one of its offices in Calgary, Alberta Canada a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Canadian Lenders, and the Canadian Commitments of, and principal amounts of the Canadian Advances owing to, each Lender pursuant to the terms hereof from time to time (the “Canadian Register”; together with the US Register, the “Registers”). The entries in the applicable Register shall be conclusive absent manifest error, and the Borrowers and the Lender Parties may treat each Person whose name is recorded in the applicable Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.

     (c) Participations. Any Lender may at any time, without the consent of, or notice to, any Borrower or any Administrative Agent, sell participations to any Person (other than a natural person or the Company or any of the Company’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitments and/or the Advances owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrowers and the Lender Parties shall continue to deal solely and directly with such Lender Party in connection with such Lender Party’s rights and obligations under this Agreement.

     Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in clauses (a), (b), (c) or (d) of this Section 9.6 (that adversely affects such Participant). Subject to paragraph (d) of this Section, each Borrower agrees that each Participant shall be entitled to the benefits of, and subject to the requirements of, Sections 2.12, 2.13 and 2.15 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (a) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 7.4 as though it were a Lender, provided such Participant agrees to be subject to Section 2.14(f) as though it were a Lender.

     (d) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Section 2.13 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Applicable Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.15 unless the Applicable Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of such Borrower, to comply with Section 2.15(d), in which case Section 2.15 shall be applied as if such

Participant had become a Lender and had acquired its interest by assignment pursuant to paragraph (a) of this Section; provided that, in no event shall such Participant be entitled to receive any greater payment under Section 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant.

     (e) Certain Pledges. Any Lender may at any time pledge or assign a security interest 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; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 9.7 Notices, Etc.

     (a) Notices Generally. Except in the case of notices and other communications expressly permitted to be given by telephone (and except as provided in paragraph (b) below), all notices and other communications provided for herein shall be in writing and shall be delivered by hand or overnight courier service, mailed by certified or registered mail or sent by telecopier as follows: (i) if to the US Borrower, the Canadian Borrower, or any other Credit Party, at the applicable address (or telecopier numbers) set forth on Schedule III; (ii) if to the US Administrative Agent, Canadian Administrative Agent, US Issuing Lender or Canadian Issuing Lender, at the applicable address (or telecopier numbers) set forth on Schedule III; and (iii) if to a Lender, to it at its address (or telecopier number) set forth in its Administrative Questionnaire. Notices sent by hand or overnight courier service, or mailed by certified or registered mail, shall be deemed to have been given when received; notices sent by telecopier shall be deemed to have been given when sent (except that, if not given during normal business hours for the recipient, shall be deemed to have been given at the opening of business on the next business day for the recipient). Notices delivered through electronic communications to the extent provided in paragraph (b) below, shall be effective as provided in said paragraph (b).

     (b) Electronic Communications.

     (i) The Borrowers and the Lenders agree that the Administrative Agents may make any material delivered by any Borrower to any Administrative Agent, as well as any amendments, waivers, consents, and other written information, documents, instruments and other materials relating to the Company, any of its Subsidiaries, or any other materials or matters relating to this Agreement, the Notes or any of the transactions contemplated hereby (collectively, the “Communications”) available to the Lenders by posting such notices on an electronic delivery system (which may be provided by any Administrative Agent, an Affiliate of an Administrative Agent, or any Person that is not an Affiliate of an Administrative Agent), such as IntraLinks, or a substantially similar electronic system (the “Platform”). The Borrowers acknowledge that (i) the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution, (ii) the Platform is provided “as is” and “as available” and (iii) none of the Administrative Agents nor any of their respective Affiliates warrants the accuracy, completeness, timeliness, sufficiency, or sequencing of the Communications posted on the Platform. The Administrative Agents and their respective Affiliates expressly disclaim with respect to the Platform any liability for errors in transmission, incorrect or incomplete downloading, delays in posting or delivery, or problems accessing the Communications posted on the Platform and any liability for any losses, costs, expenses or liabilities that may be suffered or incurred in connection with the Platform. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by either Administrative Agent or any of their respective Affiliates in connection with the Platform.

     (ii) Each Lender agrees that notice to it (as provided in the next sentence) (a “Notice”) specifying that any Communication has been posted to the Platform shall for purposes of this Agreement constitute effective delivery to such Lender of such information, documents or other materials comprising such Communication. Each Lender agrees (i) to notify, on or before the date such Lender becomes a party to this Agreement, the Applicable Administrative Agent in writing of such Lender’s e-mail address to which a Notice may be sent (and from time to time thereafter to ensure that such Administrative Agent has on record an effective e-mail address for such Lender) and (ii) that any Notice may be sent to such e-mail address.

     (c) Change of Address, Etc. Any party hereto may change its address or telecopier number for notices and other communications hereunder by notice to the other parties hereto.

Section 9.8 Confidentiality. Each Administrative Agent, each Lender and each Issuing Lender agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and other representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Company and its obligations, (g) with the consent of the Company or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to any Lender Party or any of their respective Affiliates on a nonconfidential basis from a source other than a Credit Party. For purposes of this Section, “Information” means all information received from the Company or any of its Subsidiaries relating to the Company or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to Lender Party on a nonconfidential basis prior to disclosure by the Company or any of its Subsidiaries. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 9.9 Business Loans. Each Borrower warrants and represents that the Obligations are and shall be for business, commercial, investment or other similar purposes and not primarily for personal, family, household or agricultural use, as such terms are used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time to time in effect.

Section 9.10 Usury Not Intended. It is the intent of each Borrower and each Lender in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable laws of the State of Texas, the United States from time to time in effect, and any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement. In furtherance thereof, the Lenders and the Borrowers stipulate and

agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes of this Agreement and all other Credit Documents, “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Agreement or any other Credit Document; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received or paid on the Advances, include amounts which by applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and each Lender receiving same shall credit the same on the principal of its Advances owing to such Lender (or if all such Advances shall have been paid in full, refund said excess to the Applicable Borrower). In the event that the maturity of the Advances are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Advances (or, if the applicable Advances shall have been paid in full, refunded to the applicable Borrower of such interest). In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Borrowers and the Lenders shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal parts during the period of the full stated term of the Advances all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Advances. The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith.

Section 9.11 Usury Recapture. In the event the rate of interest chargeable under this Agreement or any other Credit Document at any time is greater than the Maximum Rate, the unpaid principal amount of the Advances shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on the Advances equals the amount of interest which would have been paid or accrued on the Advances if the stated rates of interest set forth in this Agreement or applicable Credit Document had at all times been in effect. In the event, upon payment in full of the Advances, the total amount of interest paid or accrued under the terms of this Agreement and the Advances is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement or such Credit Document had, at all times, been in effect, then the applicable Borrower shall, to the extent permitted by applicable law, pay the Applicable Administrative Agent for the account of the applicable Lender Party an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on Advances owed to it if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on such Advances if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid under this Agreement or any Credit Document on Advances owed to it. In the event the any Lender Party ever receive, collect or apply as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Advances, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the applicable Borrower.

Section 9.12 Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due from any Borrower hereunder in the currency expressed to be payable herein (the “specified currency”) into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with usual and customary banking procedures the US Administrative Agent could purchase the specified currency with such other currency at any of the US Administrative Agent’s offices in the United States of America on the Business Day preceding that on which final judgment is given. The obligations of the Borrowers in respect of any sum due to any Lender Party hereunder shall, notwithstanding any judgment in a

currency other than the specified currency, be discharged only to the extent that on the Business Day following receipt by such Lender, such Issuing Lender, such Underlying Issuer or such Administrative Agent (as the case may be) of any sum adjudged to be so due in such other currency such Lender, such Issuing Lender such Underlying Issuer or such Administrative Agent (as the case may be) may in accordance with normal, reasonable banking procedures purchase the specified currency with such other currency. If the amount of the specified currency so purchased is less than the sum originally due to such Lender, such Issuing Lender, such Underlying Issuer or such Administrative Agent, as the case may be, in the specified currency, the applicable Borrower agrees, to the fullest extent that it may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender, such Issuing Lender, such Underlying Issuer or such Administrative Agent, as the case may be, against such loss, and if the amount of the specified currency so purchased exceeds (a) the sum originally due to any Lender, such Issuing Lender, such Underlying Issuer or such Administrative Agent, as the case may be, in the specified currency and (b) any amounts shared with other Lenders as a result of allocations of such excess as a disproportionate payment to such Lender under Section 2.14, each Lender, Issuing Lender, each Underlying Issuer or each Administrative Agent, as the case may be, agrees to promptly remit such excess to the Applicable Borrower.

Section 9.13 Payments Set Aside. To the extent that any payment by or on behalf of any Borrower is made to any Lender Party, or any Lender Party exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by any Lender Party in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred, and (b) each Lender and each Issuing Lender severally agrees to pay to the Applicable Administrative Agent upon demand its applicable share (without duplication) of any amount so recovered from or repaid by the Applicable Administrative Agent, plus interest thereon from the date of such demand to the date such payment is made at a rate per annum equal to the applicable Overnight Rate from time to time in effect, in the applicable currency of such recovery or payment. The obligations of the Lenders and the Issuing Lenders under clause (b) of the preceding sentence shall survive the payment in full of the Obligations and the termination of this Agreement.

Section 9.14 Governing Law; Submission to Jurisdiction.

     (a) Governing Law. This Agreement, the Notes and the other Credit Documents (unless otherwise expressly provided therein) shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 346 of the Texas Finance Code, as amended (relating to revolving loans and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. ▇▇▇. Art. ▇▇▇▇, ▇▇. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law limiting the amount of interest payable for its account, such Lender shall utilize the indicated (weekly) rate ceiling from time to time in effect.

     (b) Submission to Jurisdiction. Each Borrower irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any Federal or Texas state court sitting in ▇▇▇▇▇▇ County, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Credit Document, or for recognition or enforcement of any judgment, and each of the parties hereto irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such Texas State court or, to the fullest extent permitted by applicable law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on

the judgment or in any other manner provided by law. Nothing in this Agreement or in any other Credit Document shall affect any right that any Lender Party may otherwise have to bring any action or proceeding relating to this Agreement or any other Credit Document against any Credit Party or its properties in the courts of any jurisdiction.

     (c) Waiver of Venue. Each Borrower irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any other Credit Document 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 applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

     (d) Service of Process. Each party hereto irrevocably consents to service of process in the manner provided for notices in Section 9.7. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by applicable law.

Section 9.15 Execution and Effectiveness.

     (a) Execution in Counterparts. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Credit Documents, and any separate letter agreements with respect to fees payable to the Administrative Agents, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. This Agreement shall become effective when it shall have been executed by the Administrative Agents and when the US Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. 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.

     (b) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, or any state laws based on the Uniform Electronic Transactions Act.

Section 9.16 Waiver of Jury. EACH PARTY HERETO HEREBY IRREVOCABLY 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 AGREEMENT OR ANY OTHER CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON 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 AGREEMENT AND THE OTHER CREDIT DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 9.17 USA PATRIOT ACT Notice. Each Lender that is subject to the Act (as hereinafter defined) and each Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of each Borrower and other information that will allow such Lender or such Administrative Agent, as applicable, to identify such Borrower in accordance with the Act.

Section 9.18 Termination for Departing Lenders. Notice of termination given on the Effective Date to any Lender (as defined in the Restated Agreement) which is not also a Lender under this Agreement (“Departing Lender”) shall constitute effective termination of the Restated Agreement with respect to such Departing Lender and upon payment in full of all outstanding Advances, interest and fees under the Restated Agreement owing to such Departing Lender by the Applicable Borrower, the Applicable Borrower shall be released of any obligations to such Departing Lender under the Restated Agreement other than reimbursement and indemnity obligations which by the terms of the Restated Agreement survive.

Section 9.19 Third Party Secured Parties.

     (a) Each Swap Counterparty that are owed Obligations which are secured by any Lien granted pursuant to a Security Document shall be deemed a third party beneficiary hereof and of the provisions of the other Credit Documents solely for purposes of any reference in a Credit Document to the parties for whom the Applicable Administrative Agent is acting. Each Administrative Agent hereby agrees to act as agent for such Swap Counterparties and, by virtue of accepting of the benefits of the Credit Documents and the Liens granted thereby, each such Person shall be automatically deemed to have appointed each Administrative Agent as its agent; it being understood and agreed that the rights and benefits of each Swap Counterparty under the Credit Documents consist exclusively of such Swap Counterparty being a beneficiary of the Liens and security interests (and, if applicable, guarantees) granted to Administrative Agents and the right to share in payments and collections out of the Collateral as more fully set forth herein. In connection with any such distribution of payments and collections, each Administrative Agent shall be entitled to assume no amounts are owing to any Swap Counterparty unless such Swap Counterparty has provided written notification to the Applicable Administrative Agent of the amount that is owing to it and such notification is received by Applicable Administrative Agent a reasonable period of time prior to the making of such distribution.

     (b) Each Swap Counterparty that is not a party hereto, by its acceptance of the benefits of the Credit Documents and the Liens granted thereby, shall be deemed to have agreed to the terms of this Section 9.19 and the terms of Article VIII above.

Section 9.20 Cure of Defaulting Lender. If the applicable Borrower, Administrative Agent, Issuing Lender and Swingline Lender agree in writing in their discretion that a Lender that is a Defaulting Lender or a Potential Defaulting Lender should no longer be deemed to be a Defaulting Lender or Potential Defaulting Lender, as the case may be, such Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will, to the extent applicable, purchase such portion of outstanding Advances of the other Lenders and/or make such other adjustments as the Applicable Administrative Agent may determine to be necessary to cause the US Outstandings, Canadian Outstandings, and applicable Letter of Credit Exposure to be on a pro rata basis in accordance with their respective Commitments in the respective Facilities, whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender; provided that no adjustments will be made retroactively with respect to interest accrued or payments made by or on behalf of the Borrowers while such Lender was a Defaulting Lender; and provided, further, that except to

the extent otherwise expressly agreed by the affected parties, no cessation of any Lender being considered as a Defaulting Lender or Potential Defaulting Lender hereunder will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender or Potential Defaulting Lender.

     PURSUANT TO SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED IN THE LOAN AGREEMENT EXCEEDS $50,000.00 IN VALUE IS NOT ENFORCEABLE UNLESS THE LOAN AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT PARTY’S AUTHORIZED REPRESENTATIVE.

     THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN LOAN AGREEMENT, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED INTO THE LOAN AGREEMENT. THIS WRITTEN AGREEMENT AND THE CREDIT DOCUMENTS, AS DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES WITH RESPECT TO THE SUBJECT MATTERS SET FORTH HEREIN AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

     THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
