Subject to the terms and conditions set forth herein, each Lender agrees to make CDOR Revolving Loans and Canadian Prime Rate Loans to the Canadian Borrowers denominated in Canadian Dollars and each Lender agrees to make ABR Revolving Loans and Eurodollar Revolving Loans to the Company denominated in US Dollars from time to time during the Availability Period in an aggregate principal amount not to exceed at any time outstanding the amount of such Lender’s Revolving Loan Commitment; provided that (i) any Canadian Dollar Loans funded by a Designated Lender shall constitute a utilization against the Revolving Loan Commitment of its Designating Lender for all purposes hereunder, (ii) after giving effect to any Revolving Loan, (A) such Lender’s Revolving Credit Exposure shall not exceed such Lender’s Revolving Loan Commitment, (B) the sum of the total Revolving Credit Exposures shall not exceed the Aggregate Revolving Loan Commitments, and (iii) at no time shall the aggregate outstanding Canadian Dollar Loans exceed $15,000,000 (with the Equivalent Amount of each such Canadian Dollar Loan in US Dollars for purposes of this sentence being measured only as of the time made). Within the foregoing limits and subject to the terms and conditions set forth in this Agreement, the Borrowers may borrow, prepay and reborrow Revolving Loans.

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

(b) Subject to Section 2.14, each Revolving Borrowing denominated in Canadian Dollars shall be comprised entirely of Canadian Prime Rate Loans or CDOR Rate Loans and each Revolving Borrowing denominated in US Dollars shall be comprised entirely of ABR Loans or Eurodollar Loans as the Company may request in accordance herewith. Swingline Loans may be denominated in Canadian Dollars or in US Dollars. Each Swingline Loan denominated in Canadian Dollars shall be a Canadian Prime Rate Loan and each Swingline Loan denominated in US Dollars shall be an ABR Loan. Each Lender at its option may make any Eurodollar Revolving Loan and CDOR Rate Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrowers to repay such Loan in accordance with the terms of this Agreement.

(c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $50,000.00 and not less

than $500,000.00. At the time each CDOR Borrowing is initially made, such Borrowing shall be in an aggregate amount that is an integral multiple of Cdn $50,000.00 and not less than Cdn $500,000.00 (with the Equivalent Amount of each such CDOR Borrowing in US Dollars for purposes of this sentence being measured only as of the beginning of such Interest Period). At the time that each ABR Revolving Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000.00 and not less than $100,000.00, and at the time that each Canadian Prime Rate Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of Cdn $100,000.00 and not less than Cdn $100,000.00; provided that an ABR Revolving Borrowing or Canadian Prime Rate Revolving Borrowing may be in an aggregate amount that is equal to the entire unused balance of the Aggregate Revolving Loan Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.06(e). Each Swingline Loan shall be in an amount not less than US or Cdn $100,000.00. Borrowings of more than one Type and Class may be outstanding at the same time.

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

(e) For any Lender which is a Designating Lender, any Canadian Dollar Loan shall be made by its Designated Lender.

SECTION 2.03. Requests for Revolving Borrowings. To request a Revolving Borrowing, the Company shall notify the Administrative Agent of such request by telephone (a) in the case of a CDOR Rate Borrowing or Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three (3) Business Days before the date of the proposed Borrowing or (b) in the case of a Canadian Prime Rate Borrowing or an ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of the proposed Borrowing; provided that any such notice of a Canadian Prime Rate Borrowing or an ABR Revolving Borrowing to finance the reimbursement of an LC Disbursement as contemplated by Section 2.06(e) may be given not later than 10:00 a.m., New York City time, on the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent and signed by the Company. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(ii) the aggregate amount of the requested Borrowing (in US Dollars or, with respect to Canadian Dollar Loans, in Canadian Dollars);

(iv) whether such Borrowing is to be an ABR Borrowing, a Canadian Prime Rate Borrowing, a CDOR Borrowing, or a Eurodollar Borrowing;

(v) in the case of a CDOR Rate Borrowing or a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and

(vi) the location and number of the applicable Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.07.

If no election as to the Type of Revolving Borrowing is specified, then the requested Revolving Borrowing shall be a Canadian Prime Rate Borrowing or an ABR Borrowing. If no Interest Period is specified with respect to any requested CDOR Borrowing or Eurodollar Revolving Borrowing, then the Company shall be deemed to have selected an Interest Period of one month’s duration (or 30 days in the case of a CDOR Borrowing). Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Revolving Loan to be made as part of the requested Borrowing.

(a) Request for Increase. The Company may, at any time and from time to time, request, by notice to the Administrative Agent, the Administrative Agent’s approval of an increase of the Aggregate Revolving Loan Commitments (a “Revolving Commitment Increase”) within the limitations hereafter described, which request shall set forth the amount of each such requested Revolving Commitment Increase. Administrative Agent shall notify all the Lenders of any such request and provide them the first right to participate in the same proportions that their respective Applicable Revolving Loan Percentages bear to those of all the Lenders who elect to participate therein. Within twenty (20) days of such request, the Administrative Agent shall advise the Company of its approval or disapproval of such request; failure to so advise the Company shall constitute disapproval. If the Administrative Agent approves any such Revolving Commitment Increase, then the Aggregate Revolving Commitment may be so increased (up to the amount of such approved Revolving Commitment Increase) by having one or more of the Lenders increase the amount of their then existing Revolving Loan Commitments and, if existing the Lenders do not choose to participate to the extent necessary for the applicable Revolving Commitment Increase to be provided entirely by existing the Lenders, by having one or more new the Lenders become the Lenders party to this Agreement. Any Revolving Commitment Increase shall be subject to the following limitations and conditions: (i) any Revolving Commitment Increase shall not be less than $5,000,000.00 (and shall be in integral multiples of $5,000,000.00 if in excess thereof); (ii) no Revolving Commitment Increase shall increase the Aggregate Revolving Loan Commitments to an amount in excess of $175,000,000.00; (iii) the provisions of Section 9.04(b) shall apply in respect of any Increasing Lender that is not a Lender prior to the Revolving Commitment Increase, as if such Increasing Lender were an assignee of a Revolving Loan Commitment, (iv) the Borrowers shall have executed and delivered to the Administrative Agent such Note or Notes as the applicable Increasing Lender shall request to reflect such Revolving Commitment Increase (or, in the case of a new Lender, such Lender’s Revolving Commitment); (v) the Company shall have delivered to the Administrative Agent opinions of counsel (substantially similar to the forms of opinions provided for in Section 4.01 modified to apply to the Revolving Commitment Increase and each Note executed and delivered in connection therewith); (vi) the Guarantors shall have consented in writing to the Revolving Commitment Increase and shall have agreed in writing that their Subsidiary Guarantees continue in full force and effect; and (vii) the Company, Subsidiaries and each Lender shall have executed and delivered such other instruments and documents as the Administrative Agent shall have reasonably requested in connection with such Revolving Commitment Increase. The form and substance of the documents required under clauses (iv) through (vii) above shall be fully acceptable to the Administrative Agent. The Administrative Agent shall provide written notice to all of the Lenders hereunder of any Revolving Commitment Increase.

(b) Revolving Loans by Increasing Lenders. Upon the effective date of any increase in the Aggregate Revolving Loan Commitments pursuant to the provisions hereof, which effective date shall be mutually agreed upon by the Company, each Increasing Lender and the Administrative Agent, each Increasing Lender shall make a payment to the Administrative Agent in an amount sufficient, upon the application of such payments by all Increasing Lenders to the reduction of the outstanding Revolving Loans held by the Lenders, to cause the principal amount outstanding under the Revolving Loans made by each Lender (including, as applicable, any Increasing Lender) to be in the amount of its Applicable Revolving Loan Percentage (upon the effective date of such increase). The Borrowers hereby irrevocably authorize each Increasing Lender to fund to the Administrative Agent the payment required to be made pursuant to the immediately preceding sentence for application to the reduction of the outstanding Revolving Loans held by the other the Lenders hereunder. If, as a result of the repayment of the Revolving Loans provided for in this Section 2.04(b), any payment of a Eurodollar Revolving Borrowing or CDOR Revolving Borrowing occurs on a day which is not the last day of the applicable Interest Period, the Borrowers will pay to the Administrative Agent for the benefit of any of the Lenders holding such Borrowing any loss or cost incurred by such Lender resulting therefrom in accordance with Section 2.16. Upon the effective date of such increase in the Aggregate Revolving Loan Commitments, all Eurodollar Revolving Loans outstanding hereunder (including any Revolving Loans made by the Increasing Lenders on such date) shall be ABR Loans, subject to the Company’s right to convert the same to Eurodollar Loans on or after such date in accordance with the provisions of Section 2.08.

(c) Increasing Lenders’ Participation in Facility LCs. Upon the effective date of any increase in the Aggregate Revolving Loan Commitments and the making of the Revolving Loans by the Increasing Lenders in accordance with the provisions of Section 2.04(b), each Increasing Lender shall also be deemed to have irrevocably and unconditionally purchased and received, without recourse or warranty, from the Lenders party to this Agreement immediately prior to the effective date of such increase, an undivided interest and participation in any Facility LCs then outstanding, ratably, such that each Lender (including each Increasing Lender) holds a participation interest in each such Facility LC in proportion equal to its Applicable Revolving Loan Percentage upon the effective date of such increase in the Aggregate Revolving Loan Commitments.

(d) No Obligation to Increase Revolving Loan Commitment. Nothing contained herein shall constitute, or otherwise be deemed to be, a commitment or agreement on the part of the Borrowers or the Administrative Agent to give or grant any Lender the right to increase its Revolving Loan Commitment hereunder at any time or a commitment or agreement on the part of any Lender to increase its Revolving Loan Commitment hereunder at any time, and no Revolving Loan Commitment of a Lender shall be increased without its prior written approval, which it may grant or deny in its sole discretion.

(a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans denominated in Canadian Dollars to the Canadian Borrowers and Swingline Loans denominated in US Dollars to the Company from time to time during the Availability Period, in an aggregate principal amount at any time outstanding not to exceed $10,000,000.00 (with the Equivalent Amount of each Canadian Dollar Swingline Loan in US Dollars for purposes of this sentence being measured only as of the time made); provided that (i) after giving effect to any Swingline Loan, the sum of the total Revolving Credit Exposures shall not exceed the Aggregate Revolving Loan Commitments, and (ii) the Swingline Lender shall not be required to make a

Swingline Loan to refinance an outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, the Company may borrow, prepay and reborrow Swingline Loans.

(b) To request a Swingline Loan, the Company shall notify the Administrative Agent of such request by telephone (confirmed by telecopy), not later than 12:00 noon, New York City time, on the day of a proposed Swingline Loan. Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan, as well as the name of the Borrower that will receive the Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Company. The Swingline Lender shall make each Swingline Loan available to the applicable Borrower by means of a credit to the general deposit account of such Borrower with the Swingline Lender (or, in the case of a Swingline Loan made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e), by remittance to the Issuing Bank) by 5:00 p.m., New York City time, on the requested date of such Swingline Loan.

(c) The Swingline Lender may by written notice given to the Administrative Agent not later than 10:00 a.m., New York City time, on any Business Day require the Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which the Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each Lender, specifying in such notice such Lender’s Applicable Revolving Loan Percentage of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s Applicable Revolving Loan Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the Revolving Loan Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.07 with respect to Revolving Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders. The Administrative Agent shall notify the Company of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Administrative Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from the Company (or other party on behalf of the Company) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Administrative Agent, as applicable, if and to the extent such payment is required to be refunded to the Company for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Borrowers of any default in the payment thereof.

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

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

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

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

that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Facility LC, the Borrowers shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if the Company shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Company prior to such time on such date, then not later than 12:00 noon, New York City time, on (i) the Business Day that the Company receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Company receives such notice, if such notice is not received prior to such time on the day of receipt; provided that, if such LC Disbursement is not less than $500,000.00, the Company may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 or 2.05 that such payment be financed with a Canadian Prime Rate Borrowing, an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and, to the extent so financed, the Borrowers’ obligation to make such payment shall be discharged and replaced by the resulting Canadian Prime Rate Borrowing, ABR Revolving Borrowing or Swingline Loan. If the Borrowers fail to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrowers in respect thereof and such Lender’s Applicable Revolving Loan Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Revolving Loan Percentage of the payment then due from the Borrowers, in the same manner as provided in Section 2.07 with respect to Loans made by such Lender (and Section 2.07 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrowers pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that the Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such the Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of a Canadian Prime Rate Loan, ABR Revolving Loan or Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrowers of their obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The Borrowers’ obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Facility LC or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Facility LC proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Facility LC against presentation of a draft or other document that does not comply with the terms of such Facility LC, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of set-off against, the Borrowers’ obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Facility LC or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or

delivery of any draft, notice or other communication under or relating to any Facility LC (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrowers to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrowers to the extent permitted by applicable law) suffered by any of the Borrowers that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Facility LC comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Facility LC, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Facility LC.

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

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrowers shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrowers reimburse such LC Disbursement, at the rate per annum then applicable to Canadian Prime Rate Revolving Loans (if the LC Disbursement is in Canadian Dollars) or ABR Revolving Loans (if the LC Disbursement is in US Dollars); provided that, if the Borrowers fail to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.13(d) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrowers, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrowers shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.12(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Facility LCs to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the

rights and obligations of an Issuing Bank under this Agreement with respect to Facility LCs issued by it prior to such replacement, but shall not be required to issue additional Facility LCs.

(j) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Company receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, the Lenders with LC Exposure representing greater than fifty percent (50%) of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrowers shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to any of the Borrowers described in clause (h) or (i) of ARTICLE VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrowers under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrowers’ risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrowers for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of the Lenders with LC Exposure representing greater than fifty percent (50%) of the total LC Exposure), be applied to satisfy other obligations of the Borrowers under this Agreement. If the Borrowers are required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrowers within three Business Days after all Events of Default have been cured or waived.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be made as provided in Section 2.05. The Administrative Agent will make such Loans available to the Company or the applicable Canadian Borrower, as the case may be, by promptly crediting the amounts so received, in like funds, to an account of the Company or the applicable Canadian Borrower, maintained with the Administrative Agent in Tulsa, Oklahoma or elsewhere and designated by the Company in the applicable Borrowing Request; provided that ABR Revolving Loans and Canadian Prime Rate Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.06(e) shall be remitted by the Administrative Agent to the Issuing Bank.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrowers a corresponding

amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrowers severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrowers to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of either the Federal Funds Effective Rate (in the case of US Dollar-denominated amounts) or the Administrative Agent’s cost of funds (in the case of Canadian Dollar-denominated amounts) and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrowers, the interest rate applicable to ABR Loans (in the case of US Dollar-denominated amounts) or Canadian Prime Rate Revolving Loans (in the case of Canadian Dollar-denominated amounts). If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

(a) Each Revolving Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a CDOR Revolving Borrowing or Eurodollar Revolving Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Company may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Revolving Borrowing or CDOR Revolving Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Company may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing provided that a Borrowing in one currency may only be converted to another Type of Borrowing denominated in the same currency as the Borrowing to be so converted. This Section shall not apply to Swingline Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section, the Company shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Company were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Company.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02:

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

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

(iii) whether the resulting Borrowing, if in Canadian Dollars, is to be a Canadian Prime Rate Borrowing or a CDOR Rate Borrowing, or, if in US Dollars, is to be an ABR Borrowing or a Eurodollar Borrowing; and

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

If any such Interest Election Request requests a CDOR Borrowing or Eurodollar Borrowing but does not specify an Interest Period, then the Company shall be deemed to have selected an Interest Period of 30 days for a CDOR Borrowing or one month for a Eurodollar Borrowing.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion, if any, of each Borrowing affected by such Interest Election Request.

(e) If the Company fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing, then (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

(f) If the Company fails to deliver a timely Interest Election Request with respect to a CDOR Rate Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to a Canadian Prime Rate Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a CDOR Rate Borrowing and (ii) unless repaid, each CDOR Rate Borrowing shall be converted to a Canadian Prime Rate Borrowing at the end of the Interest Period applicable thereto.

(a) Unless previously terminated, the Revolving Loan Commitments shall terminate on the Revolving Credit Termination Date.

(b) The Company may at any time terminate, or from time to time reduce, the Revolving Loan Commitments; provided that (i) each reduction of the Revolving Loan Commitments shall be in an amount that is an integral multiple of $5,000,000.00 and not less than $5,000,000.00 and (ii) the Company shall not terminate or reduce the Revolving Loan Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11, the aggregate Revolving Credit Exposures would exceed the Aggregate Revolving Loan Commitments.

(c) The Company shall notify the Administrative Agent of any election to terminate or reduce the Revolving Loan Commitments under paragraph (b) of this Section at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election

and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Company pursuant to this Section shall be irrevocable; provided that a notice of termination of the Revolving Loan Commitments delivered by the Company may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Company (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Revolving Loan Commitments shall be permanent. Each reduction of the Revolving Loan Commitments shall be made ratably among the Lenders in accordance with their respective Revolving Loan Commitments.

(a) The Borrowers hereby unconditionally promise to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan on the Revolving Credit Termination Date; and (ii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Revolving Credit Termination Date and the first date after such Swingline Loan is made that is the 15^th or last day of a calendar month and is at least two (2) Business Days after such Swingline Loan is made; provided that on each date that a Revolving Borrowing is made, the Borrowers shall repay all Swingline Loans then outstanding.

(b) If at any time the total of all Revolving Credit Exposures exceeds the Aggregate Revolving Loan Commitments, the Borrowers shall immediately repay Revolving Loans in an aggregate principal amount sufficient to eliminate any such excess. If the Revolving Loans have been paid in full, such repayment (or the portion thereof remaining after payment of the Revolving Loans in full) shall be applied to cash collateralize the Letters of Credit.

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

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

(e) The entries made in the accounts maintained pursuant to paragraph (e) or (f) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrowers to repay the Loans in accordance with the terms of this Agreement.

(f) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, Agent shall prepare and the Borrowers shall execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form

payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). Each Note in favor of a Designating Lender shall be deemed to include and represent the obligations to repay the Canadian Dollar Loans funded by the Designated Lender as part of such Designating Lender’s Revolving Loan Commitment.

(a) The Borrowers shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b).

(b) The Company shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed by telecopy) of any prepayment by the Borrowers hereunder (i) in the case of prepayment of a CDOR Rate Borrowing or Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three (3) Business Days before the date of prepayment, (ii) in the case of prepayment of a Canadian Prime Rate Borrowing or an ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Revolving Loan Commitments as contemplated by Section 2.09, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.09. Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Revolving Borrowing shall be in an amount that would be permitted in the case of an advance of a Revolving Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.13.

(a) The Borrowers agree to pay to the Administrative Agent for the account of each Lender an Unused Revolving Credit Facility Fee, which shall accrue at the rate per annum set forth below on the daily amount of the unused Revolving Loan Commitment of such Lender during the period from and including the Closing Date to but excluding the date on which such Revolving Loan Commitment terminates:

The Unused Revolving Credit Facility Fee shall be determined in accordance with the foregoing table based on the Senior Leverage Ratio as reflected in the then most recent financial statements delivered pursuant to Section 5.01(a) or (b). Adjustments, if any, to the Unused

Revolving Credit Facility Fee shall be effective on the Margin Adjustment Date. If the Company fails to deliver the financial statements to the Administrative Agent at the time required pursuant to Section 5.01(a) or (b), then the Unused Revolving Credit Facility Fee shall be adjusted to the highest fee set forth in the foregoing table until five (5) Business Days after such financial statements are so delivered. If at any time previously issued financial statements are adjusted or restated by the Company after delivery pursuant to Section 5.01(a) or (b) to correct an error contained therein, then any resulting changes in the Unused Revolving Credit Facility Fee that would arise from any change in the Senior Leverage Ratio as determined according to the adjusted or restated financial statements shall be effective retroactively as if such adjusted or restated financial statements had been delivered at the time originally required pursuant to Section 5.01. Accrued Unused Revolving Credit Facility Fees shall be payable in arrears on the first day of each fiscal quarter (currently January 1, April 1, July 1, and October 1 of each year) and on the date on which the Revolving Loan Commitments terminate, commencing on the first such date to occur after the date hereof; provided that (i) any Unused Revolving Credit Facility Fees accruing after the date on which the Revolving Loan Commitments terminate shall be payable on demand and (ii) any additional Unused Revolving Credit Facility Fees accruing due to adjusted or restated financial statements and determined after they would have been payable hereunder shall be payable on demand. All Unused Revolving Credit Facility Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

The Borrowers agree to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Facility LCs, which shall accrue at a rate per annum equal to the Applicable Rate for Eurodollar Revolving Loans in the case of Facility LCs denominated in US Dollars and at a rate per annum applicable to the Applicable Rate for Canadian Prime Rate Revolving Loans in the case of Facility LCs denominated in Canadian Dollars, on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Closing Date to but excluding the later of the date on which such Lender’s Revolving Loan Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee of 0.125% per annum of the face of amount of each Facility LC, as well as the Issuing Bank’s standard fees with respect to the issuance, documentation, processing, amendment, renewal or extension of any Facility LC or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Closing Date; provided that all such fees shall be payable on the date on which the Revolving Loan Commitments terminate and any such fees accruing after the date on which the Revolving Loan Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within ten (10) days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) The Company agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Company and the Administrative Agent.

(c) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for

distribution, in the case of facility fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

(d) The Company shall pay the cost of all audits, inspections, valuations and/or field examinations conducted pursuant to Section 5.06, provided that if no Event of Default shall be continuing, the Company shall not be required to pay for (i) any such audit, inspection, valuation and/or field examination conducted prior to the date one (1) year after the Closing Date or (ii) more than two (2) such audits, inspections, valuations and/or field examinations per calendar year.

(a) The Loans comprising each ABR Borrowing (including each Swingline Loan denominated in US Dollars) shall bear interest at the Alternate Base Rate plus the Applicable Rate. The Loans comprising each Canadian Prime Rate Borrowing (including each Swingline Loan denominated in Canadian Dollars) shall bear interest at the Canadian Prime Rate plus the Applicable Rate.

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

(c) The Loans comprising each CDOR Borrowing shall bear interest at the CDOR Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(d) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrowers hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section, (ii) in the case of overdue interest on any CDOR Rate Borrowing, 2% plus the rate applicable to CDOR Rate Loans as provided in paragraph (c) of this Section, (iii) in the case of any other amount denominated in US Dollars, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section, or (iv) in the case of any other amount denominated in Canadian Dollars, 2% plus the rate applicable to Canadian Prime Rate Loans as provided in paragraph (a) of this Section.

(e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Revolving Loan Commitments; provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of a Canadian Prime Rate Revolving Loan or an ABR Revolving Loan prior to the end of the Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, (iii) in the event of any conversion of any CDOR Rate Loan or Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion, and (iv) any additional accrued interest accruing due to adjusted or restated financial statements to correct an error contained therein and determined after such interest would have been payable hereunder shall be payable on demand.

(f) All interest hereunder shall be computed on the basis of a year of 360 days, except that (i) interest computed by reference to the Alternate Base Rate at times when the Alternate Base

Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day) and (ii) interest computed by reference to the Canadian Prime Rate or the CDOR Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate, Canadian Prime Rate, CDOR Rate, or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

(g) For purposes of the Interest Act (Canada), where in this Agreement or any other Loan Document a rate of interest is to be calculated on the basis of a year of 360, 365 or 366 days, the yearly rate of interest to which the rate is equivalent is the rate multiplied by the number of days in the year for which the calculation is made and divided by 360, 365 or 366, as applicable.

(h) If any provision of this Agreement or of any of the other Loan Documents would obligate any Credit Party to make any payment of interest or other amount payable to the Lenders in an amount or calculated at a rate which would be prohibited by law or would result in a receipt by the Lenders of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)) then, notwithstanding such provisions, such amount or rate shall be deemed to have been adjusted with retroactive effect to the maximum amount or rate of interest, as the case may be, as would not be so prohibited by law or so result in a receipt by the Lenders of interest at a criminal rate, such adjustment to be effected, to the extent necessary, as follows: (1) firstly, by reducing the amount or rate of interest required to be paid to the Lenders under this Section 2.13, and (2) thereafter, by reducing any fees, commissions, premiums and other amounts required to be paid to the Lenders which would constitute “interest” for purposes of Section 347 of the Criminal Code (Canada). Notwithstanding the foregoing, and after giving effect to all adjustments contemplated thereby, if the Lenders shall have received an amount in excess of the maximum permitted by that section of the Criminal Code (Canada), the Credit Parties shall be entitled, by notice in writing to the Administrative Agent, to obtain reimbursement from the Lenders in an amount equal to such excess and, pending such reimbursement, such amount shall be deemed to be an amount payable by the Lenders to the Borrowers. Any amount or rate of interest referred to in this Section 2.13(g) shall be determined in accordance with generally accepted actuarial practices and principles as an effective annual rate of interest over the term that the applicable Loan remains outstanding on the assumption that any charges, fees or expenses that fall within the meaning of “interest” (as defined in the Criminal Code (Canada)) shall, if they relate to a specific period of time, be pro-rated over that period of time and otherwise be pro-rated over the period from the earliest possible date to the Revolving Credit Termination Date and, in the event of a dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by the Administrative Agent shall be conclusive for the purposes of such determination.

(i) In the event that any financial statement delivered pursuant to Section 5.01(a) or (b) is shown to be inaccurate (regardless of whether this Agreement or the Revolving Loan Commitments are in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Rate for any period (an “Applicable Period”), the Company shall immediately (a) deliver to the Administrative Agent a corrected Compliance Certificate for such Applicable Period, (b) determine the Applicable Rate for such Applicable Period based upon the corrected compliance certificate, and (c) immediately pay to the Administrative Agent for the benefit of the Lenders the accrued additional interest and other fees

owing as a result of such increased Applicable Rate for such Applicable Period, which payment shall be promptly distributed by the Administrative Agent to the Lenders entitled thereto.

(a) If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

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

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

then the Administrative Agent shall give notice thereof to the Company and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Company and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing; provided that if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

(i) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the CDOR Rate for such Interest Period; or

(ii) the Administrative Agent is advised by the Required Lenders that the CDOR Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Company and the Lenders by telephone or facsimile as promptly as practicable thereafter and, until the Administrative Agent notifies the Company and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the continuation of any Borrowing as, a CDOR Rate Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a CDOR Borrowing, such Borrowing shall be made as a Canadian Prime Rate Borrowing.

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

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

(iii) subject any Recipient to any Taxes on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto (other than (A) Indemnified Taxes and (B) Other Connection Taxes on gross or net income, profits or revenue (including value-added or similar Taxes));

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

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

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

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Company of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan or CDOR Rate Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan or CDOR Rate Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan or CDOR Rate Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Company pursuant to Section 2.19, then, in any such event, the Borrowers shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan or CDOR Rate Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate or the CDOR Rate plus the Applicable Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for US Dollar deposits of a comparable amount and period to such Eurodollar Loan from other banks in the eurodollar market, or for Canadian Dollar deposits of a comparable amount and period to such CDOR Rate Loan from other banks in the Canadian bankers’ acceptance market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrowers and shall be conclusive absent manifest error. The Borrowers shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(a) Withholding of Taxes; Gross-Up. Each payment by any Credit Party under any Loan Document shall be made without withholding for any Taxes, unless such withholding is required by any law. If any Withholding Agent determines, in its sole discretion exercised in good faith, that it is so required to withhold Taxes, then such Withholding Agent may so withhold and shall timely pay the full amount of withheld Taxes to the relevant Governmental Authority in accordance with applicable law. If such Taxes are Indemnified Taxes, then the amount payable by such Credit Party shall be increased as necessary so that, net of such withholding (including such withholding applicable to additional amounts payable under this Section), the applicable Recipient receives the amount it would have received had no such withholding been made.

(b) Payment of Other Taxes by the Borrowers. The Borrowers shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes by any Credit Party to a Governmental Authority, such Credit Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(d) Indemnification by the Borrowers. The Borrowers shall indemnify each Recipient for any Indemnified Taxes that are paid or payable by such Recipient in connection with any Loan

Document (including amounts paid or payable under this Section 2.17(d)) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.17(d) shall be paid within 10 days after the Recipient delivers to the Company a certificate stating the amount of any Indemnified Taxes so paid or payable by such Recipient and describing the basis for the indemnification claim. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. Such Recipient shall deliver a copy of such certificate to the Administrative Agent.

(e) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent for any Taxes (but, in the case of any Indemnified Taxes, only to the extent that the Borrowers have not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrowers to do so) attributable to such Lender that are paid or payable by the Administrative Agent in connection with any Loan Document and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 2.17(e) shall be paid within 10 days after the Administrative Agent delivers to the applicable Lender a certificate stating the amount of Taxes so paid or payable by the Administrative Agent. Such certificate shall be conclusive of the amount so paid or payable absent manifest error.

(i) Any Lender that is entitled to an exemption from, or reduction of, any applicable withholding Tax with respect to any payments under any Loan Document shall deliver to the Company and the Administrative Agent, at the time or times reasonably requested by the Company or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Company or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender, if requested by the Company or the Administrative Agent, shall deliver such other documentation prescribed by law or reasonably requested by the Company or the Administrative Agent as will enable the Company or the Administrative Agent to determine whether or not such Lender is subject to any withholding (including backup withholding) or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.17(f)(ii)(A) through (F) below) shall not be required if in the Lender’s judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. Upon the reasonable request of the Company or the Administrative Agent, any Lender shall promptly update any form or certification previously delivered pursuant to this Section 2.17(f). If any form or certification previously delivered pursuant to this Section expires or becomes obsolete or inaccurate in any respect with respect to a Lender, such Lender shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify the Company and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so.

(ii) Without limiting the generality of the foregoing, if any Borrower is a U.S. Person, any Lender with respect to such Borrower shall, if it is legally eligible to do so, deliver to the Company and the Administrative Agent (in such number of copies reasonably requested by the Borrower and the Administrative Agent) on or prior to the date on which such Lender becomes a party hereto, duly completed and executed copies of whichever of the following is applicable:

(A) in the case of a Lender that is a U.S. Person, IRS Form W-9 certifying that such Lender is exempt from U.S. Federal backup withholding tax;

(B) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (1) with respect to payments of interest under any this Agreement or any other Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “interest” article of such tax treaty and (2) with respect to any other applicable payments under this Agreement, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. Federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(C) in the case of a Foreign Lender for whom payments under this Agreement constitute income that is effectively connected with such Lender’s conduct of a trade or business in the United States, IRS Form W-8ECI;

(D) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code both (1) IRS Form W-8BEN and (2) a certificate substantially in the form of Exhibit H (a “U.S. Tax Certificate”) to the effect that such 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 Company within the meaning of Section 881(c)(3)(B) of the Code (c) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (d) conducting a trade or business in the United States with which the relevant interest payments are effectively connected;

(E) in the case of a Foreign Lender that is not the beneficial owner of payments made under this Agreement (including a partnership or a participating Lender) (1) an IRS Form W-8IMY on behalf of itself and (2) the relevant forms prescribed in clauses (A), (B), (C), (D) and (F) of this paragraph (f)(ii) that would be required of each such beneficial owner or partner of such partnership if such beneficial owner or partner were a Lender; provided, however, that if the Lender is a partnership and one or more of its partners are claiming the exemption for portfolio interest under Section 881(c) of the Code, such Lender may provide a U.S. Tax Certificate on behalf of such partners; or

(F) any other form prescribed by law as a basis for claiming exemption from, or a reduction of, U.S. Federal withholding Tax together with such supplementary documentation necessary to enable the Company or the Administrative Agent to determine the amount of Tax (if any) required by law to be withheld.

(iii) If a payment made to a Lender under any Loan Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the

Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has or has not complied with such Lender’s obligations under FATCA and, as necessary, to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.17(f)(iii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(g) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.17 (including additional amounts paid pursuant to this Section 2.17), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including any Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid to such indemnified party pursuant to the previous sentence (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 2.17(g), in no event will any indemnified party be required to pay any amount to any indemnifying party pursuant to this Section 2.17(g) if such indemnified party can demonstrate in good faith that such payment would place such indemnified party in a less favorable position (on a net after-Tax basis) than such indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 2.17(g) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the indemnifying party or any other Person.

(a) The Borrowers shall make each payment required to be made by the Borrowers hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, Section 2.16 or Section 2.17, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Section 2.15, 2.16, 2.17 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in the currency in which the applicable Obligations are denominated, and, if not otherwise specified, in US Dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due

hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

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

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

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(c), 2.06(d) or (e), 2.07(b), 2.18(d) or 9.03(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

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

(b) If any Lender requests compensation under Section 2.15, or if 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 2.17, or if any Lender becomes a Defaulting Lender, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrowers shall have received the prior written consent of the Administrative Agent (and if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

SECTION 2.20. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) fees shall cease to accrue on the unfunded portion of the Revolving Loan Commitment of such Defaulting Lender pursuant to Section 2.12;

(b) the Revolving Loan Commitment and Revolving Credit Exposure of such Defaulting Lender shall not be included in determining whether all the Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 9.02), provided that any waiver, amendment or modification requiring the consent of all the Lenders or each affected Lender which affects such Defaulting Lender differently than other affected the Lenders shall require the consent of such Defaulting Lender;

(i) all or any part of such Swingline Exposure and LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting Lender’s Swingline Exposure and LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 4.02 are satisfied at such time; and

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrowers shall within one Business Day following notice by the Administrative Agent (x) first, prepay such Swingline Exposure and (y) second, cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.06(j);

(iii) if the Borrowers cash collateralize any portion of such Defaulting Lender’s LC Exposure pursuant to Section 2.20(c), the Borrowers shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.12 with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to Section 2.20(c), then the fees payable to the Lenders pursuant to Section 2.12 shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; or

(v) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to Section 2.20(c), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all facility fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment that was utilized by such LC Exposure) and letter of credit fees payable under Section 2.12 with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated; and

(d) so long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrowers in accordance with Section 2.20(c), and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.20(c)(i) (and Defaulting Lenders shall not participate therein).

(e) In the event that the Administrative Agent, the Company, the Issuing Bank and the Swingline Lender each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the Swingline Exposure and LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans of the other the Lenders (other than Swingline Loans) as the Administrative shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage.

(a) The Borrowers are accepting and do hereby accept joint and several liability hereunder in regard to all Canadian Dollar Loans and all Obligations related thereto, in consideration of the financial accommodation to be provided by the Lenders under this Agreement, for the mutual benefit, directly and indirectly, of the Borrowers and in consideration of the undertakings of each of the Borrowers to accept joint and several liability as set forth herein. Except as otherwise expressly provided herein, each Borrower hereby waives notice of acceptance of its joint and several liability and any and all demands, notices and other formalities of every kind in connection with this Agreement. Each Borrower hereby assents to, and waives notice of, any extension or postponement of the time for the payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by the Lenders at any time or times in respect of any default by any Borrower in the performance or satisfaction of any term, covenant, condition or provision of this Agreement, any and all other indulgences whatsoever by the Lenders in respect of any of the Obligations, and the taking, addition, substitution or release, in whole or in part, at any time or times, of any security for any of the Obligations or the addition, substitution or release, in whole or in part, of any Borrower. Without limiting the generality of the foregoing, each Borrower assents to any other action or delay in acting or any failure to act on the part of the Administrative Agent or the Lenders, including, without limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with applicable laws or regulations thereunder which might, but for the provisions of this Section, afford grounds for terminating, discharging or relieving such Borrower, in whole or in part, from any of its obligations under this Section, it being the intention of each Borrower that, so long as any of the Obligations hereunder remain unsatisfied, the obligations of such Borrower under this Section shall not be discharged except by performance and then only to the extent of such performance. The obligations of each Borrower under this Section shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect to any reconstruction or similar proceeding with respect to any Borrower or the Lenders. The provisions of this Section shall remain in effect until all the Obligations shall have been paid in full or otherwise fully satisfied and all Revolving Loan Commitments are terminated and of no further force and effect. If at any time, any payment, or any part thereof, made in respect of any of the Obligations, is rescinded or must otherwise be restored or returned by the Lenders upon the insolvency, bankruptcy or reorganization of any of the Borrowers, or otherwise, the provisions of this Section will forthwith be reinstated and in effect as though such payment had not been made. Notwithstanding any provision to the contrary contained herein or in any other of the Loan Documents, the obligations of each Borrower hereunder shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance under Section 548 of the Bankruptcy Code of the United States or any comparable provisions of any applicable Federal, state, provincial, territorial or foreign bankruptcy, insolvency, receivership or similar law now or hereafter in effect.

(b) Nothing herein is intended to or shall be construed to modify or restrict any Existing Guarantee to which any Canadian Borrower is a party.

(c) The Company is hereby appointed by each of the Canadian Borrowers as its contractual representative hereunder and under each other Loan Document, and each of the Canadian Borrowers irrevocably authorizes the Company to act as the contractual representative of such Canadian Borrower in regard to this Agreement and the other Loan Documents.

The Borrowers represent and warrant to the Administrative Agent and Lenders that:

SECTION 3.01. Organization; Powers. Each of the Company and its Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.

SECTION 3.02. Authorization; Enforceability. The Transactions are within each Borrower’s corporate powers and have been duly authorized by all necessary corporate and, if required, stockholder action. This Agreement has been duly executed and delivered by the Borrowers and constitutes a legal, valid and binding obligation of each Borrower, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

SECTION 3.03. Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except for the filing of a Current Report on Form 8-K with the Securities and Exchange Commission and except such as have been obtained or made and are in full force and effect, (b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of the Company or any of its Subsidiaries or any order of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon the Company or any of its Subsidiaries or its assets, or give rise to a right thereunder to require any payment to be made by the Company or any of its Subsidiaries, and (d) will not result in the creation or imposition of any Lien on any asset of the Company or any of its Subsidiaries other than those Liens which are created or imposed hereunder or pursuant to the Collateral Documents.

SECTION 3.04. Financial Condition; No Material Adverse Change; Absence of Default.

(a) The Company has heretofore furnished to the Lenders its consolidated balance sheet and statements of income, stockholders equity and cash flows (i) as of and for the fiscal year ended June 30, 2011, reported on by Deloitte & Touche LLP, independent registered public accountants. Such financial statements present fairly, in all material respects, the financial position and results of operations and cash flows of the Company and its consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP.

(b) Since June 30, 2011, there has been no adverse change in the business, assets, operations, prospects or condition, financial or otherwise, of the Company and its Subsidiaries, taken as a whole, that could reasonably be expected to have a Material Adverse Effect.

(a) Each of the Company and the Guarantors has good title to, or valid leasehold interests in, all its real and personal property material to its business, except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes and except as set forth on Schedule 3.05.

(b) Each of the Company and the Guarantors owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by the Company and Guarantors does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

(a) Except as discussed in Schedule 3.06, there are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Company, threatened against or affecting the Company or any of its Subsidiaries (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or (ii) that involve this Agreement or the Transactions.

(b) In the ordinary course of its business the officers of the Company consider the effect of Environmental Laws on the business of the Company and its Subsidiaries, in the course of which they identify and evaluate potential risks and liabilities to which the Company or its Subsidiaries may be subject due to Environmental Laws. On the basis of this consideration, except with respect to matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, neither the Company nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability. Neither the Company nor any Subsidiary has received any notice to the effect that its operations are not in material compliance with any of the requirements of applicable Environmental Laws or are the subject of any federal, state, provincial or territorial investigation evaluating whether any remedial action is needed to respond to a release of any toxic or hazardous waste or substance into the environment, which non-compliance or remedial action could reasonably be expected to have a Material Adverse Effect.

SECTION 3.07. Compliance with Laws and Agreements. Each of the Company and its Subsidiaries is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

SECTION 3.08. Investment Company Status. Neither the Company nor any of its Subsidiaries is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

SECTION 3.09. Taxes. Each of the Company and its Subsidiaries has timely filed or caused to be filed all Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the Company or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with Agreement Accounting Principles and as to which no Lien exists or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of any Taxes or other governmental charges are adequate. Each of the Company and its Subsidiaries has withheld all employee withholdings and has made all employer contributions to be withheld and made by it pursuant to applicable law on account of the Canada and Quebec pension plans, employment insurance and employee income taxes.

(a) Except as set forth on Schedule 3.10(a), (i) no ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect and (ii) neither the Company nor any other member of the Controlled Group has incurred, or is reasonably expected to incur, any withdrawal liability to Multiemployer Plans in excess of $500,000.00 in the aggregate.

(b) None of the Company or any of its Subsidiaries has any Canadian Pension Plan.

(c) Except where the failure to perform any obligation or make any withholding, collection or payment, as applicable, could not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect: (i) all obligations of the Company and its Subsidiaries (including fiduciary, funding, investment, administration and reporting obligations) required to be performed by them in connection with the Canadian Benefit Plans and the funding agreements therefor have been performed (ii) all contributions or premiums required to be made or paid by the Company and its Subsidiaries to the Canadian Benefit Plans have been made or paid in a timely fashion in accordance with the terms of such plans and all applicable laws, and (iii) all employee contributions to the Canadian Benefit Plans by way of authorized payroll deduction or otherwise have been properly withheld or collected by the Company and its Subsidiaries and have been fully paid into those plans in compliance with the plans and applicable laws. There have been no improper withdrawals or applications of the assets of the Canadian Benefit Plans, except where any such withdrawals or applications could not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. There is no proceeding, action, suit or claim (other than routine claims for benefits) pending or threatened involving the Canadian Benefit Plans, and no facts exist which could reasonably be expected to give rise to that type of proceeding, action, suit or claim, except where the outcome thereof could not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect. No promises of benefit improvements under the Canadian Benefit Plans the Company or any of its Subsidiaries have been made except where improvement could not have a Material Adverse Effect.

SECTION 3.11. Plan Assets; Prohibited Transactions; ERISA. Except as to salary deferrals before they are put into trust, no Borrower is an entity deemed to hold “plan assets” within the meaning of 29 C.F.R. § 2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the meaning of Section 4975 of the Code). Neither the execution of this Agreement nor the extending of Loans or issuance of Facility

LCs hereunder gives rise to a prohibited transaction within the meaning of Section 406 of ERISA or Section 4975 of the Code or results in or causes an ERISA Event.

SECTION 3.12. Disclosure. The Company has disclosed to the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. The reports, financial statements, certificates and other information furnished by or on behalf of the Company to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or delivered hereunder (as modified or supplemented by other information so furnished), when taken as a whole, do not contain any material misstatement of fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial information, the Company represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time.

SECTION 3.13. Subsidiaries. Schedule 3.13 contains an accurate list of and other information regarding all Subsidiaries of the Company as of the date of this Agreement, setting forth their respective jurisdictions of organization and the percentage of their respective capital stock or other ownership interests owned by the Company or other Subsidiaries. Deliberately omitted from Schedule 3.13 are Matrix Service, Inc., Panama (formed in Panama) and San Luis Tank S.A. de C.V. (formed in Mexico), both of which the Company has represented and does hereby represent to Agent and the Lenders are now dormant and neither of which (i) the Company has any plan or intention to revive or utilize in any way or (ii) has any assets or operations whatsoever. All of the issued and outstanding shares of capital stock or other ownership interests of all Subsidiaries have been (to the extent such concepts are relevant with respect to such ownership interests) duly authorized and issued and are fully paid and non-assessable.

SECTION 3.14. Material Agreements. Neither the Company nor any Subsidiary is subject to any charter or other corporate restriction which could reasonably be expected to have a Material Adverse Effect. Neither the Company nor any Subsidiary is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in (i) any agreement to which it is a party, which default could reasonably be expected to have a Material Adverse Effect or (ii) any agreement or instrument evidencing or governing Indebtedness, including but not limited to any of the Loan Documents.

SECTION 3.15. Post-Retirement Benefits. The present value of the expected cost of post-retirement medical (excluding the cost of continuation coverage as required by §4980(B) of the Code or by similar, applicable state insurance laws) and insurance benefits payable by the Company and its Subsidiaries to its employees and former employees, as estimated by the Company in accordance with procedures and assumptions deemed reasonable by the Required Lenders, does not exceed $500,000.00.

(a) Immediately after the consummation of the transactions to occur on the date hereof and immediately following the making of each Loan, if any, made on the date hereof and after giving effect to the application of the proceeds of such Loans, (i) the fair value of the assets of the Company and its Subsidiaries on a consolidated basis, at a fair valuation, will exceed the debts and liabilities, subordinated, contingent or otherwise, of the Company and its Subsidiaries on a consolidated basis;

(ii) the present fair saleable value of the property of the Company and its Subsidiaries on a consolidated basis will be greater than the amount that will be required to pay the probable liability of the Company and its Subsidiaries on a consolidated basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (iii) the Company and its Subsidiaries on a consolidated basis will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (iv) the Company and its Subsidiaries on a consolidated basis will not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted after the date hereof.

(b) The Company does not intend to, or to permit any of its Subsidiaries to, and does not believe that it or any of its Subsidiaries will, incur debts beyond its ability to pay such debts as they mature, taking into account the timing of and amounts of cash to be received by it or any such Subsidiary and the timing of the amounts of cash to be payable on or in respect of its Indebtedness or the Indebtedness of any such Subsidiary.

SECTION 3.17. Payment and Performance Bonds. Attached hereto as Schedule 3.18 is a list and brief description of all payment and performance bonds to which the Company or any of the Subsidiaries is a party as of the Closing Date.

The Administrative Agent may consult with legal counsel (who may be counsel for the Company), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

SECTION 8.06. Sub-Agents. The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

SECTION 8.07. Successor. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section 8.07, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Company. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Company, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in Tulsa, Oklahoma, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

SECTION 8.08. Lenders’ Reliance; Decisions. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in

taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

(a) Except in the case of notices and other communications expressly permitted to be given by telephone or by electronic communication (and subject to 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 telecopy, as provided in the signature pages hereto.

(b) Notices and other communications to the Lenders and the Administrative Agent hereunder may be delivered or furnished by electronic communications (e.g. E-Mail); provided that the foregoing shall not apply to notices pursuant to ARTICLE II unless otherwise agreed by the Administrative Agent and the applicable Lender.

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

(d) Each Designating Lender shall serve as the administrative agent of its Designated Lender and shall on behalf of the Designated Lender: (i) receive any and all payments made for the benefit of the Designated Lender and (ii) give and receive all communications and notices and take all actions hereunder, including, without limitation, votes, approvals, waivers, consents and amendments under or relating to this Agreement and the other Loan Documents. Any such notice, communication, vote, approval, waiver, consent or amendment shall be signed by the Designating Lender on behalf of the Designated Lender and need not be signed by the Designated Lender on its own behalf. The Borrowers, the Administrative Agent and the Lenders may rely thereon without any requirement that the Designated Lender sign or acknowledge the same. The Designated Lender may not assign or transfer all or any portion of its interest hereunder or under any other Loan Document, other than in conjunction with an assignment by its Designating Lender in accordance with the provisions of this Agreement.

(a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrowers therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the

purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Facility LC shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrowers and the Required Lenders or by the Borrowers and the Administrative Agent with the written consent of the Required Lenders; provided that (i) no such agreement shall (A) increase the Revolving Loan Commitment of any Lender without the written consent of such Lender, (B) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (C) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Revolving Loan Commitment, without the written consent of each Lender affected thereby, (D) change Section 2.10(b) or (c) in a manner that would alter the sharing of payments required thereby, without the written consent of each Lender, (E) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of the Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, or (F) release any Guarantor from any Subsidiary Guaranty or release the Liens on a Substantial Portion of the Collateral except in accordance with the terms of any Loan Document, without the written consent of each Lender and (ii) and no such agreement shall change Section 2.10(b) or (c) provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender hereunder without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be.

(a) The Borrowers shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Facility LC or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Facility LCs issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Facility LCs.

(b) The Borrowers shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a

result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Facility LC or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Facility LC if the documents presented in connection with such demand do not strictly comply with the terms of such Facility LC), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Company or any of its Subsidiaries, or any Environmental Liability related in any way to the Company or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and non-appealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

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

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

(e) All amounts due under this Section shall be payable not later than five (5) days after written demand therefor.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Facility LC), except that (i) the Borrowers may not assign or otherwise transfer any of their respective rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by any Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Facility LC), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Loan Commitment (if any) and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Company, provided that no consent of the Company shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee;

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of any Revolving Loan Commitment to an assignee that is a Lender immediately prior to giving effect to such assignment; and

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Revolving Loan Commitment or Loans of any Class, the amount of the Revolving Loan Commitment or Loans 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 Administrative Agent) shall not be less than the lesser of (i) $5,000,000.00 or (ii) the remaining amount of the assigning Lender’s Revolving Loan Commitment (calculated as of the date of such assignment), if any, and outstanding Loans, unless each of the Company and the Administrative Agent otherwise consent, provided that no such consent of the Company shall be required if an Event of Default has occurred and is continuing;

(B) except in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, 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, provided that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of one Class of Revolving Loan Commitments or Loans;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500.00;

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and

(E) no Designated Lender shall have any right to make any assignment of its rights and obligations hereunder, provided that any assignment by any Designating Lender in accordance herewith shall include an assignment of the same proportionate part of all its Designated Lender’s rights and obligations under this Agreement.

For the purposes of this Section 9.04(b), the term “Approved Fund” has the following meaning:

“Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the 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 Section 2.15, Section 2.16, Section 2.17, and Section 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 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.

(iv) The Administrative Agent, acting for this purpose as an agent of the Company, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Revolving Loan Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrowers, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrowers, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.05(c), Section 2.06(d) or Section 2.06(e), Section 2.07(b), Section 2.18(d) or Section 9.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c) (i) Any Lender may, without the consent of the Borrowers, the Administrative Agent, the Issuing Bank or the Swingline Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this

Agreement (including all or a portion of its Revolving Loan Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrowers, the Administrative Agent, the Issuing Bank and the other the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.01(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Section 2.15, Section 2.16, and Section 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.15 or 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers’ prior written consent. A Participant that would be a Foreign Lender if it were a Lender, or a non-resident of Canada for purposes of the ITA in the case of any participation of rights and/or obligations with respect to a Canadian Borrower, shall not be entitled to the benefits of Section 2.17 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.17(e) as though it were a Lender.

(d) 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 without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(e) The Borrowers authorize each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Company and its Subsidiaries.

(f) (i) Any Lender may at any time after approval of the Administrative Agent and the Company designate not more than one Designated Lender to fund Borrowings on behalf of such Designating Lender subject to the terms of this Section 9.04(f), and the provisions of Section 9.04(b) and (c) shall not apply to such designation. No Lender may have more than one Designated Lender at any time. Such designation may occur either by the execution of the signature pages hereof by such Lender and Designated Lender next to the appropriate “Designating Lender” and “Designated Lender” captions, or by execution by such parties of a Designation Agreement subsequent to the date hereof in a form acceptable to the Administrative Agent (a “Designation Agreement”). The parties to each such designation occurring subsequent to the execution date hereof shall execute and deliver to the Administrative Agent and the Company for their acceptance a Designation Agreement. Upon

such receipt of an appropriately completed Designation Agreement executed by a Designating Lender and a designee representing that it is a Designated Lender and consented to by the Company and the Administrative Agent, the Administrative Agent will accept such Designation Agreement and will give prompt notice thereof to the Company and the other Lenders, whereupon, from and after the effective date specified in the Designation Agreement, the Designated Lender shall become a party to this Agreement with a right to fund Canadian Dollar Loans on behalf of its Designating Lender.

(ii) Each Designating Lender shall be and remain obligated to the Company, the Administrative Agent and the Lenders for each and every of the obligations of the Designating Lender and its related Designated Lender with respect to this Agreement.

(iii) Effective upon a Designated Lender’s execution of this Agreement or delivery of a Designation Agreement, as applicable:

(A) The Designated Lender appoints the Designating Lender as Designated Lender’s administrative agent and attorney in fact and grants to Designating Lender an irrevocable power of attorney to receive payments made for the benefit of Designated Lender, to deliver and receive all communications and notices under this Agreement and the other Loan Documents and to exercise on the Designated Lender’s behalf all rights to vote and to grant and make approvals, waivers, consents of amendments to or under this Agreement or the other Loan Papers. Any document executed by Designating Lender on Designated Lender’s behalf in connection with this Agreement or the Loan Documents shall be binding on the Designated Lender. The Borrowers, the Administrative Agent and each of the Lenders may rely on and are beneficiaries of the preceding provision.

(B) Each Designating Lender unconditionally agrees to pay or reimburse its Designated Lender and save it harmless against all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed or asserted by any of the parties to the Loan Documents against the Designated Lender, in its capacity as such, in any way relating to or arising out of this Agreement or any other Loan Documents or any action taken or omitted by the Designated Lender hereunder or thereunder, provided that the Designating Lender shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements if the same results from the Designated Lender’s gross negligence or willful misconduct.

SECTION 9.05. Disclosure. The Borrowers and each Lender hereby (i) acknowledge and agree that (a) one or more Affiliates of JPMorgan Chase are or may become direct or indirect equity investors in the Company, and (b) JPMorgan Chase and/or its Affiliates from time to time may hold other investments in, make other loans to or have other relationships with the Company, and (ii) waive any liability of JPMorgan Chase or such Affiliate to the Company or any Lender, respectively, arising out of or resulting from such investments, loans or relationships other than liabilities arising out of the gross negligence or willful misconduct of JPMorgan Chase or its Affiliates.

SECTION 9.06. Survival. All covenants, agreements, representations and warranties made by the Borrowers herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties

hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Facility LCs, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Facility LC is outstanding and so long as the Revolving Loan Commitments have not expired or terminated. The provisions of Section 2.15, Section 2.16, Section 2.17 and Section 9.03 and ARTICLE VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Facility LCs and the Revolving Loan Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.07. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent 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. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.08. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.09. Right of Set-off. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrowers against any of and all the obligations of the Borrowers now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of set-off) which such Lender may have.

SECTION 9.10. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of Oklahoma.

(b) Each Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any United States federal court or Oklahoma state court sitting in Tulsa, Oklahoma, and any appellate court from any thereof, in any action or proceeding

arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such state or, to the extent permitted by 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 shall affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Borrowers or any of their properties in the courts of any jurisdiction.

(c) Each Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 9.12. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.13. Confidentiality. (a) Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ and Approved Funds’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (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, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (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 Borrowers and their obligations, (g) with the consent of the Borrowers or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a non-confidential basis from a source other than the Borrowers. For the purposes of this Section, “Information” means all information received from the Borrowers relating to the Borrowers or their business, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a non-confidential basis prior to disclosure by the Borrowers; provided that, in the case of information received from the Borrowers after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

(b) EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 9.13(a) FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING THE BORROWER AND ITS RELATED PARTIES OR THEIR RESPECTIVE SECURITIES, THAT IT HAS DEVELOPED COMPLIANCE PROCEDURES REGARDING THE USE OF MATERIAL NON-PUBLIC INFORMATION AND THAT IT WILL HANDLE SUCH MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH THOSE PROCEDURES AND APPLICABLE LAW, INCLUDING FEDERAL AND STATE SECURITIES LAWS.

SECTION 9.14. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

SECTION 9.15. USA PATRIOT Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies the Borrowers that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of the Borrowers and other information that will allow such Lender to identify the Borrowers in accordance with the Act.

(a) The obligations of the Borrowers or any of the other Credit Parties hereunder and under the other Loan Documents to make payments in US Dollars or in Canadian Dollars, as the case may be (the “Obligation Currency”), shall not be discharged or satisfied by any tender or recovery

pursuant to any judgment expressed in or converted into any currency other than the Obligation Currency, except to the extent that such tender or recovery results in the effective receipt by the Administrative Agent or a Lender of the full amount of the Obligation Currency expressed to be payable to the Administrative Agent or such Lender under this Agreement or the other Loan Documents. If, for the purpose of obtaining or enforcing judgment against any Credit Party in any court or in any jurisdiction, it becomes necessary to convert into or from any currency other than the Obligation Currency (such other currency being hereinafter referred to as the “Judgment Currency”) an amount due in the Obligation Currency, the conversion shall be made, at the Administrative Agent’s quoted rate of exchange prevailing, in each case, as of the date immediately preceding the day on which the judgment is given (such Business Day being hereinafter referred to as the “Judgment Currency Conversion Date”).

(b) If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount due, the Credit Parties each covenant and agree to pay, or cause to be paid, such additional amounts, if any (but in any event not a lesser amount), as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial award at the rate of exchange prevailing on the Judgment Currency Conversion Date.

(c) Any amount due from a Credit Party under this Section 9.16(c) shall be due as a separate debt and shall not be affected by judgment being obtained for any other amounts due under or in respect of any of the Loan Documents.

(d) For purposes of determining the prevailing rate of exchange, such amounts shall include any premium and costs payable in connection with the purchase of the Obligation Currency.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
