THE CREDITS

SECTION 2.1. Commitments. (a) Subject to the terms and conditions set forth herein, each Lender agrees to make Revolving Loans denominated in US Dollars and Alternative Currencies (other than Canadian Dollars) to the Borrowers from time to time and Revolving Loans denominated in Canadian Dollars to the Canadian Borrowers and to the Specified US Borrowers from time to time during the Availability Period in an aggregate principal amount that will not result in (i) such Lender’s Revolving Credit Exposure exceeding such Lender’s Commitment, (ii) the aggregate amount of all Revolving Loans to the Canadian Borrowers (together with the aggregate face amount of all Letters of Credit issued for the account of the Canadian Borrowers) exceeding the Canadian Borrower Sublimit, or (iii) the aggregate outstanding amount of all Revolving Loans exceeding the aggregate Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrowers may borrow, prepay and reborrow Revolving Loans.

(b) On the Effective Date, the Existing Loan held by the Existing Lender under the Existing Credit Agreement shall automatically, and without any action on the part of any Person, be deemed to be a Loan hereunder and such Loan shall be deemed to satisfy such Existing Lender’s obligation under paragraph (a) above to the extent of the unpaid principal amount of the Existing Loan held by such Existing Lender. Each Existing Lender whose Commitment hereunder is decreasing (a “Decreasing Lender”) shall, by assignments to the Increasing Lenders (as defined below), sell a portion of the Loans held by it to each Increasing Lender, and each Lender whose Commitment hereunder is increasing (an “Increasing Lender”) relative to that under the Existing Credit Agreement shall, by assignments from the Decreasing Lenders, purchase a portion of the Loans held by such Decreasing Lender, in each case in such amounts (and the Decreasing Lenders and the Increasing Lenders shall, through the Administrative Agent, make such

NYDOCS/1287812.1

additional adjustments among themselves as shall be necessary) so that after giving effect to such assignments and adjustments, the Lenders shall hold the Loans hereunder ratably in accordance with their respective Commitments set forth on Schedule 2.1. Such assignments shall be deemed to occur hereunder automatically, and without any requirement for additional documentation, on the Effective Date notwithstanding anything to the contrary in Section 10.4. Each Decreasing Lender represents and warrants to each Increasing Lender to which any of its Loans are being assigned that it has not created any adverse claim upon the interest being assigned by it to such Increasing Lender hereunder and that such interest is free and clear of any adverse claim.

SECTION 2.2. Loans and Borrowings. (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 respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Subject to Section 2.13, (i) each Revolving Borrowing denominated in US Dollars shall be comprised entirely of ABR Loans or Eurocurrency Loans as the Borrowers may request in accordance herewith, (ii) each Revolving Borrowing denominated in Canadian Dollars shall be comprised entirely of Canadian Prime Rate Loans or CDOR Rate Loans, (iii) each Revolving Borrowing denominated in Euros shall be comprised entirely of EURIBOR Loans and (iv) each Revolving Borrowing denominated in an Alternative Currency (other than Euros and Canadian Dollars) shall be comprised entirely of Eurocurrency Loans. Each Swingline Loan shall be an ABR Loan. Each Lender, at its option, may make any Eurocurrency Loan or EURIBOR Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan (so long as such election of a foreign branch or Affiliate does not increase the Borrowers’ costs hereunder); provided that any exercise of such option shall not affect the obligation of the applicable Borrower to repay such Loan in accordance with the terms of this Agreement. Each Lender shall, prior to the occurrence of a Default or Event of Default which has occurred and is continuing, maintain a Canadian Lending Office and make any Loans available to the Canadian Borrowers by causing its relevant Canadian Lending Office to make such Loans available.

(c) At the commencement of each Interest Period for any Eurocurrency Revolving Borrowing, any CDOR Rate Revolving Borrowing or any EURIBOR Revolving Borrowing, such Borrowing shall be in an aggregate amount that is a multiple of the Borrowing Multiple and not less than the Borrowing Minimum. At the time that each ABR Revolving Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of US$250,000 and not less than US$1,000,000, or in the case of a Canadian Prime Rate Revolving Borrowing, in an aggregate amount that is an integral multiple of Cdn$250,000 and not less than Cdn$1,000,000; provided (i) that a Canadian Prime Rate Revolving Borrowing may be in an aggregate amount that is equal to the entire balance of the Canadian Borrower Sublimit and (ii) that an ABR Revolving Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of an LC

NYDOCS/1287812.1

Disbursement as contemplated by Section 2.5(e). Each Swingline Loan shall be in an amount that is an integral multiple of $100,000 and not less than $1,000,000. Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of 12 Eurocurrency Revolving Borrowings, CDOR Rate Revolving Borrowings or EURIBOR Revolving Borrowings outstanding.

(d) Notwithstanding any other provision of this Agreement, no Borrower shall be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

SECTION 2.3. Requests for Revolving Borrowings. To request a Revolving Borrowing, the Administrative Borrower, on behalf of the requesting Borrower, shall notify the Applicable Agent of such request by telecopy of a written Borrowing Request in the form of Exhibit G or any other form approved by the London Agent or the Toronto Agent, as applicable and signed by a Responsible Officer of the Administrative Borrower (or, in the case of the Administrative Agent, by telephone confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in the form of Exhibit G or any other form approved by the Administrative Agent and signed by a Responsible Officer of the Administrative Borrower) (a) in the case of a Eurocurrency Borrowing denominated in US Dollars or a CDOR Rate Borrowing denominated in Canadian Dollars, not later than 11:00 a.m., New York City time, three Business Days before the date of the proposed Borrowing, and (b) in the case of a Eurocurrency Borrowing denominated in any other Alternative Currency (other than Canadian Dollars) or a EURIBOR Borrowing, not later than 11:00 a.m., Local Time, three Business Days before the date of the proposed Borrowing and (c) in the case of an ABR Borrowing or a Canadian Prime Rate Borrowing, not later than 11:00 a.m., Local Time, on the same day of the proposed Borrowing; provided that any such notice of an ABR Revolving Borrowing to finance the reimbursement of an LC Disbursement as contemplated by Section 2.5(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 Applicable Agent of a written Borrowing Request in a form approved by the Applicable Agent and signed by the Administrative Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.2:

(i)

the Borrower requesting such Borrowing;

(ii) the currency and the aggregate amount of the requested Borrowing;

(iii)

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

NYDOCS/1287812.1

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

(vi) the location and number of such Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.6; and

(vii) in the case of a Borrowing in an Alternative Currency, the jurisdiction from which payments of the principal and interest on such Borrowing will be made.

If no currency is specified with respect to any requested Eurocurrency Borrowing, then if the applicable Borrower is a US Borrower or a Canadian Borrower, it shall be deemed to have selected US Dollars. If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be (A) in the case of a Borrowing denominated in US Dollars made to a US Borrower or a Canadian Borrower, an ABR Borrowing, (B) in the case of a Borrowing denominated in US Dollars made to any other Borrower (other than a US Borrower or a Canadian Borrower), a Eurocurrency Borrowing, (C) in the case of a Borrowing denominated in Canadian Dollars made to a Canadian Borrower or a US Borrower, a Canadian Prime Rate Borrowing, (D) in the case of a Borrowing denominated in Euros, a EURIBOR Borrowing and (E) in the case of a Borrowing denominated in an Alternative Currency (other than Euros and Canadian Dollars), a Eurocurrency Borrowing. If no Interest Period is specified with respect to any requested Eurocurrency Borrowing, CDOR Rate Borrowing or EURIBOR Borrowing, then the applicable Borrower shall be deemed to have selected an Interest Period of one month’s (or 30 days in the case of a CDOR Rate Borrowing) duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Applicable Agent shall advise each Lender that will make a Loan as part of the requested Borrowing of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

SECTION 2.4. Swingline Loans. (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Administrative Borrower from time to time during the Availability Period, in an aggregate principal amount at any time outstanding that will not result in (i) the aggregate principal amount of outstanding Swingline Loans exceeding $15,000,000 or (ii) the aggregate Revolving Credit Exposures of all Lenders exceeding the total Commitments; provided that 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 Administrative Borrower may borrow, prepay and reborrow Swingline Loans.

(b) To request a Swingline Loan, the Administrative Borrower shall notify the Administrative Agent of such request by telephone (confirmed by telecopy), not later than 1:00 p.m., 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 and other relevant information that would be required under Section 2.3 if the Swingline Loan were a

NYDOCS/1287812.1

Revolving Loan. The Administrative Agent will promptly advise the Swingline Lender of any such notice received from the Administrative Borrower. The Swingline Lender shall make each Swingline Loan available to the Administrative Borrower by means of a credit to the general deposit account of the Administrative 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 2.5(e), by remittance to the Issuing Bank) by 3:00 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 1:00 p.m., New York City time, on any Business Day require the applicable 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 applicable Lenders will participate. Promptly upon receipt of such notice, the Administrative Agent will give notice thereof to each applicable Lender, specifying in such notice such Lender’s Applicable Percentage of such Swingline Loan or Loans. Each applicable Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to promptly pay to the Administrative Agent, for the account of the Swingline Lender, such Lender’s Applicable Percentage of such Swingline Loan or Loans. Each applicable 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 Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each applicable Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.6 with respect to Loans made by such Lender (and Section 2.6 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 Administrative Borrower 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 Administrative Borrower (or other party on behalf of the Administrative Borrower) 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 Administrative Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Administrative Borrower of any default in the payment thereof.

SECTION 2.5. Letters of Credit. (a) General. Subject to the terms and conditions set forth herein, the Administrative Borrower may request the issuance of Letters of Credit denominated in US Dollars or any Alternative Currency for its own account, or for the account

NYDOCS/0000000.1

of any other Borrower or any US Subsidiary, 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; provided that (i) with respect to any Letter of Credit issued for the account of any US Subsidiary, the Administrative Borrower shall be a co-applicant, and shall be deemed to be jointly and severally liable, with respect to any such Letter of Credit, and (ii) any Letters of Credit issued for the account of the Canadian Borrowers shall be in either US Dollars or Canadian Dollars, and (iii) the aggregate face amount of all Letters of Credit issued for the account of the Canadian Borrowers, together with the amount of Revolving Loans made to the Canadian Borrowers, shall not exceed the Canadian Borrower Sublimit. 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 Administrative Borrower to, or entered into by the Administrative Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Administrative Borrower 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 signed by a Responsible Officer of the Administrative Borrower requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank, the Administrative Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Administrative Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed US$15,000,000 and (ii) the aggregate Revolving Credit Exposures of all Lenders shall not exceed the total Commitments.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date; provided that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which in no event shall extend beyond the date referred to in clause (ii) above).

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender,

NYDOCS/1287812.1

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

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Administrative Borrower 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 Administrative Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Administrative Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on the Business Day immediately following the day that the Administrative Borrower receives such notice; provided that if such LC Disbursement is not less than US$100,000, the Administrative Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.4 that such payment be financed with an ABR Revolving Borrowing or Swingline Loan, in an equivalent amount (and if such Letter of Credit is issued in an Alternative Currency, the US Dollar Equivalent of such amount) and, to the extent so financed, the Administrative Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Revolving Borrowing or Swingline Loan. If the Administrative Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Administrative Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Administrative Borrower, in the same manner as provided in Section 2.6 with respect to Loans made by such Lender (and Section 2.7 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 Administrative Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the

NYDOCS/1287812.1

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

(f) Obligations Absolute. Subject to the provisions of the next sentence, the Administrative Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not strictly comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Administrative Borrower’s 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 Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Administrative Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Administrative Borrower to the extent permitted by applicable law) suffered by the Administrative Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Administrative Borrower by telephone (confirmed by telecopy) of such

NYDOCS/1287812.1

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 Administrative Borrower of its 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 Administrative Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Administrative Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Revolving Loans denominated in US Dollars; provided that if the Administrative Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.12(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 Administrative Borrower, 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 Administrative Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.11(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 Letters of Credit 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 Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Administrative Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 66 and 2/3% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Administrative Borrower 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 the Administrative Borrower described in clause (h) or (i) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and

NYDOCS/1287812.1

performance of the obligations of the Administrative Borrower 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 Administrative Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Monies 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 Administrative Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing greater than 66 and 2/3% of the total LC Exposure), be applied to satisfy other obligations of the Administrative Borrower under this Agreement. If the Administrative Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Administrative Borrower within three Business Days after all Events of Default have been cured or waived.

SECTION 2.6. Funding of Borrowings. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds in the applicable currency by 12:00 noon, Local Time, to the account of the Applicable 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 2.4. The Applicable Agent will make such Loans available to the applicable Borrower by promptly crediting the amounts so received, in like funds, to an account of such Borrower, designated by such Borrower in the applicable Borrowing Request; provided that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.5(e) shall be remitted by the Administrative Agent to the Issuing Bank.

(b) Unless the Applicable 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 Applicable Agent such Lender’s share of such Borrowing, the Applicable 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 applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Applicable Agent, then the applicable Lender and such Borrower severally agree to pay to the Applicable Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to such Borrower to but excluding the date of payment to the Applicable Agent, at (i) in the case of such Lender, the rate reasonably determined by the Applicable Agent to be the cost to it of funding such account or (ii) in the case of such Borrower, the interest rate applicable to the subject Loan. If such Lender pays such amount to the Applicable Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

NYDOCS/1287812.1

SECTION 2.7. Interest Elections. (a) Each Revolving Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurocurrency Revolving Borrowing, a CDOR Rate Revolving Borrowing or a EURIBOR Revolving Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the applicable Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurocurrency Revolving Borrowing, a CDOR Rate Revolving Borrowing or a EURIBOR Revolving Borrowing, may elect Interest Periods therefor, all as provided in this Section. A Borrower 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. This Section shall not apply to Swingline Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section, a Borrower shall notify the Applicable Agent of such election by telecopy (or, in the case of the Administrative Agent, by telephone) by the time that a Borrowing Request would be required under Section 2.3 if such Borrower 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 a Responsible Officer of the Administrative Borrower, on behalf of the applicable Borrower. Notwithstanding any other provision of this Section, no Borrower shall be permitted to (i) change the currency of any Borrowing, (ii) elect an Interest Period for Eurocurrency Loans, CDOR Rate Loans or EURIBOR Loans that does not comply with Section 2.2(d) or (iii) convert any Borrowing to a Borrowing of a Type not available to such Borrower pursuant to which such Borrowing was made.

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

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

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

(iii) whether the resulting Borrowing is to be (A) an ABR Borrowing or a Eurocurrency Borrowing if in US Dollars or Alternative Currencies (other than Canadian Dollars and Euros), or (B) a Canadian Prime Rate Borrowing or CDOR Rate Borrowing if in Canadian Dollars; and

(iv) if the resulting Borrowing is a Eurocurrency Borrowing, CDOR Rate Borrowing or EURIBOR Borrowing, the Interest Period to be applicable

NYDOCS/1287812.1

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 Eurocurrency Borrowing, a CDOR Rate Borrowing or a EURIBOR Borrowing but does not specify an Interest Period, then the applicable Borrower shall be deemed to have selected an Interest Period of one month’s duration (or 30 days, if applicable).

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

(e) If the applicable Borrower fails to deliver a timely Interest Election Request with respect to a Eurocurrency Revolving Borrowing, a CDOR Rate Revolving Borrowing or a EURIBOR Revolving 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 (i) in the case of a Eurocurrency Borrowing made to a US Borrower or a Canadian Borrower denominated in US Dollars, be converted to an ABR Borrowing, (ii) in the case of a CDOR Rate Borrowing made to a Canadian Borrower or a US Borrower denominated in Canadian Dollars, be converted into a Canadian Prime Rate Borrowing, and (iii) in the case of a EURIBOR Borrowing or any other Eurocurrency Borrowing, become due and payable on the last day of such Interest Period. 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 Administrative Borrower, then, so long as an Event of Default is continuing (i) no outstanding Revolving Borrowing made to a US Borrower or a Canadian Borrower denominated in US Dollars may be converted to or continued as a Eurocurrency Revolving Borrowing, (ii) no outstanding Revolving Borrowing made to an Canadian Borrower or a US Borrower denominated in Canadian Dollars may be converted to or continued as a CDOR Rate Borrowing, and (iii) unless repaid, each Eurocurrency Revolving Borrowing if in US Dollars, or a CDOR Rate Revolving Borrowing if in Canadian Dollars, made to a US Borrower or any Canadian Borrower denominated in US Dollars or Canadian Dollars, respectively, shall be converted to an ABR Borrowing or Canadian Prime Rate Borrowing, as applicable, at the end of the Interest Period applicable thereto.

SECTION 2.8. Termination and Reduction of Commitments. (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(b) The Administrative Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of the Borrowing Multiple and not less than the Borrowing Minimum, in each case for Borrowings denominated in US Dollars and (ii) the Administrative Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the aggregate Revolving Credit Exposures of all Lenders would exceed the total Commitments.

NYDOCS/1287812.1

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

SECTION 2.9. Repayment of Loans; Evidence of Debt. (a) Each Borrower hereby unconditionally promises to pay (i) to the Applicable Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan of such Borrower on the Maturity Date and (ii) to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Maturity Date and the first date after such Swingline Loan is made that is the 15th or last day of a calendar month and is at least two Business Days after such Swingline Loan is made; provided that on each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans then outstanding. On the Maturity Date, all Loans shall become absolutely due and payable and the Borrowers shall pay all of the Loans outstanding, together with any and all accrued and unpaid interest thereon.

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

(c) The 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 each Borrower to each Lender hereunder and (iii) the amount of any sum received by any Agent hereunder for the account of the Lenders and each Lender’s share thereof. The London Agent or the Toronto Agent, as applicable, shall furnish to the Administrative Agent, promptly after the making of any Loan or Borrowing with respect to which it is the Applicable Agent or the receipt of any payment of principal or interest with respect to any such Loan or Borrowing, information with respect thereto that will enable the Administrative Agent to maintain the accounts referred to in the preceding sentence.

(d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any

NYDOCS/1287812.1

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

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, applicable Borrower shall prepare, 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 10.4) 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).

SECTION 2.10. Prepayment of Loans. (a) Any Borrower 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) of this Section.

(b) The Administrative Borrower, on behalf of the applicable Borrower, shall notify the Applicable Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by a telecopy notice signed by a Responsible Officer of the Administrative Borrower) of any prepayment hereunder (i) in the case of prepayment of a Eurocurrency Revolving Borrowing denominated in US Dollars or a CDOR Rate Revolving Borrowing denominated in Canadian Dollars, not later than 11:00 a.m., Local Time, three Business Days before the date of prepayment, (ii) in the case of a Eurocurrency Revolving Borrowing denominated in an Alternative Currency (other than Canadian Dollars) or a EURIBOR Borrowing, not later than 11:00 a.m., Local Time, four Business Days before the date of prepayment, (iii) in the case of prepayment of an ABR Revolving Borrowing or a Canadian Prime Rate Revolving Borrowing, not later than 11:00 a.m., Local Time, one Business Day before the date of prepayment or (iv) 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 Commitments as contemplated by Section 2.8, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.8. Promptly following receipt of any such notice relating to a Revolving Borrowing, the Applicable 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 2.2. Each prepayment of a Revolving Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.12.

(c) If, on any date, the US Dollar Equivalent of the aggregate amount of the Revolving Credit Exposures shall exceed 105% of the aggregate Commitments as a result of currency fluctuations, then the applicable Borrowers shall, not later than the next Business Day, prepay one or more Borrowings in an aggregate principal amount

NYDOCS/1287812.1

sufficient to eliminate such excess. If, on any date, the Canadian Dollar Equivalent of the aggregate amount of the Canadian Revolving Credit Exposures shall exceed 105% of the aggregate Canadian Borrower Sublimit as a result of currency fluctuations, then the Canadian Borrowers shall, not later than the next Business Day, prepay one or more Borrowings in an aggregate principal amount sufficient to eliminate such excess.

SECTION 2.11. Fees. (a) The Administrative Borrower agrees to pay to the Administrative Agent, in US Dollars, for the account of each Lender a commitment fee, which shall accrue daily at the rates set forth below (calculated in accordance with the definition of “Applicable Rate”) on such Lender’s unused Commitment (less such Lender’s Applicable Percentage of the average daily balance of Letters of Credit), during the period from and including the Effective Date to but excluding the date on which such Commitment terminates; provided that if such Lender continues to have any Revolving Credit Exposure after its Commitment terminates with respect thereto, then such commitment fee shall continue to accrue on the daily amount of such Lender’s Swingline Exposure and LC Exposure from and including the date on which its Commitment terminates to but excluding the date on which such Lender ceases to have any Revolving Credit Exposure:

Pricing Level	Leverage Ratio:	Commitment Fee
1	≤ 0.50:1.00	0.080%
2	> 0.50:1.00 and ≤ 1.00:1.00	0.100%
3	> 1.00:1.00 and ≤ 1.50:1.00	0.125%
4	> 1.50:1.00 and ≤ 2.00:1.00	0.150%
5	> 2.00:1.00	0.200%

Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Commitments terminate, commencing on the first such date to occur after the date hereof; provided that any commitment fees accruing after the date on which the Commitments terminate shall be payable on demand. All commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) The Administrative Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurocurrency Revolving Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed

NYDOCS/1287812.1

LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee with respect to the issuance of each Letter of Credit, which shall accrue at the rate or rates per annum separately agreed upon between the Administrative Borrower and the Issuing Bank on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit 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 Effective Date; provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) 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 commitment fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances (unless miscalculated).

SECTION 2.12. Interest. (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate, and the Loans comprising each Canadian Prime Rate Borrowing shall bear interest at the Canadian Prime Rate plus the Applicable Rate.

(b) The Loans comprising each Eurocurrency Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate, the Loans comprising each CDOR Rate Borrowing shall bear interest at the CDOR Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate and the Loans comprising each EURIBOR Revolving Borrowing shall bear interest at the Adjusted EURIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by any Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other

NYDOCS/1287812.1

amount, 2% plus the rate applicable to ABR Loans or Canada Rate Prime Loans as provided in paragraph (a) of this Section.

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving Loans, upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) 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 an ABR Revolving Loan or a Canada Prime Rate 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 and (iii) in the event of any conversion of any Eurocurrency Revolving Loan, CDOR Rate Revolving Loan or EURIBOR Revolving 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. All interest shall be payable in the currency in which the applicable Loan is denominated.

(e) All interest hereunder shall be computed on the basis of a year of 360 days, except that (i) interest on Borrowings denominated in Sterling and in Canadian Dollars and (ii) 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, except in the case of Borrowings denominated in Sterling, 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, Adjusted EURIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

(f) For purposes of disclosure pursuant to the Interest Act (Canada), the annual rates of interest or fees to which the rates of interest or fees provided in this Agreement and the other Loan Documents (and stated herein or therein, as applicable, to be computed on the basis of 360 days or any other period of time less than a calendar year) are equivalent are the rates so determined multiplied by the actual number of days in the applicable calendar year and divided by 360 or such other period of time, respectively.

(g) If any provision of this Agreement or of any of the other Loan Documents would obligate any Loan 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 2.12, 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

NYDOCS/1287812.1

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 Loan 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 Borrower. Any amount or rate of interest referred to in this Section 2.12(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 Effective Date to the Maturity 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.

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

(a) the Applicable 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 Adjusted EURIBO Rate, as applicable, for such Interest Period; or

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

then the Applicable Agent shall give notice thereof to the applicable Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Applicable Agent notifies the applicable Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a Eurocurrency Borrowing or a EURIBOR Borrowing, as the case may be, shall be ineffective, and (ii) if any Borrowing Request requests a Eurocurrency Borrowing in US Dollars, such Borrowing shall be made as an ABR Borrowing; provided that if the circumstances giving rise to such notice affect less than all Types of Borrowings, then the other Types of Borrowings shall be permitted.

SECTION 2.14. Increased Costs. (a) If any Change in Law shall:

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

(ii) impose on any Lender or the Issuing Bank or the London or European interbank market any other condition affecting this Agreement,

NYDOCS/1287812.1

Eurocurrency Loans or EURIBOR Loans made by such Lender or any Letter of Credit or participation therein;

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

(b) If any Lender or the Issuing Bank determines (absent manifest error) 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 applicable Borrower 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 Administrative Borrower and shall be conclusive absent manifest error. The Administrative Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 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 applicable Borrower 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 180 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Administrative Borrower 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 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.15. Break Funding Payments. In the event of (a) the payment of any principal of any Eurocurrency Loan, CDOR Rate Loan or EURIBOR Loan other than on the last

NYDOCS/1287812.1

day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurocurrency Loan, CDOR Rate Loan or EURIBOR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurocurrency Loan, CDOR Rate Loan or EURIBOR Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.10(b) and is revoked in accordance therewith), or (d) the assignment of any Eurocurrency Loan, CDOR Rate Loan or EURIBOR Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the applicable Borrower pursuant to Section 2.18, then, in any such event, the applicable Borrower shall compensate each Lender for the actual loss, cost and expense attributable to such event. In the case of a Eurocurrency Loan, CDOR Rate Loan or EURIBOR 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, the CDOR Rate or the Adjusted EURIBO Rate, as applicable (and without reference to the Applicable Margin) 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 that 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 deposits in the applicable currency of a comparable amount and period from other banks in the London or European interbank market. A certificate of any Lender as to any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Administrative Borrower and shall be conclusive absent manifest error. The Administrative Borrower shall pay such Lender the amount shown as due on any such certificate within 30 days after receipt thereof.

SECTION 2.16. Taxes. (a) Any and all payments by or on account of any obligation of any Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if such Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) each Agent, each Lender and Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) Each relevant Borrower shall indemnify each Agent, each Lender and the Issuing Bank, within 30 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by such Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of such Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not

NYDOCS/1287812.1

such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Administrative Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Borrower to a Governmental Authority, such Borrower shall deliver to the 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.

(e) Any Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which a Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Administrative Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Administrative Borrower as will permit such payments to be made without withholding or at a reduced rate. Each Lender shall promptly notify the Administrative Agent of any change in circumstances which would modify or render invalid any such claimed exemption or reduction.

Without limiting the generality of the foregoing, if a relevant Borrower is resident for tax purposes in the United States, any Foreign Lender shall deliver to the Administrative Borrower (with a copy to the Administrative Agent) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement, upon the occurrence of any event that would result in the invalidity or obsolescence of any previously-provided form, but only in each event if such Foreign Lender is legally entitled to do so, whichever of the following is applicable:

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

(ii)

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

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (A) a certificate to the effect that such Foreign Lender is not (1) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (2) a “10 percent shareholder” of the Borrowers or Parent within the meaning of Section 881(c)(3)(B) of the Code, or (3) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (B) duly completed copies of Internal Revenue Service Form W-8BEN, or

NYDOCS/1287812.1

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

In addition, if a relevant Borrower is resident for tax purposes in the United States, any Lender that is not a Foreign Lender shall deliver to the Administrative Borrower (with a copy to the Administrative Agent) on or prior to the date on which such Lender becomes a Lender under this Agreement, upon the occurrence of any event that would result in the invalidity or obsolescence of any previously-provided form (but only in each such case if such Lender is legally entitled to deliver such form) a duly executed and properly completed copy of Internal Revenue Service Form W-9 (or applicable successor form) establishing an exemption from United States federal backup withholding tax.

(f) If any Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrowers or with respect to which such Borrower has paid additional amounts pursuant to this Section 2.16, it shall pay over such refund to such Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section 2.16 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Administrative Borrower, upon the request of such Agent or such Lender, agrees to repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Agent or such Lender in the event such Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require any Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrowers or any other Person.

(g) All amounts payable by any Borrower to the Agents, the Lenders or the Issuing Bank shall be deemed to be exclusive of any VAT. If VAT is payable on any amount paid to the Agents, the Lenders or the Issuing Bank by any Borrower, the Administrative Borrower or such other Borrower shall pay to the Agents, the Lenders or the Issuing Bank an amount equal to the amount of the VAT.

SECTION 2.17. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) Each Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.14, 2.15, 2.16 or 2.19 or otherwise) prior to 12:00 noon, Local 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 Applicable 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 Applicable Agent for the account of the Lenders to such account as the Applicable Agent shall from time to time specify in one or more notices delivered to the Administrative Borrower, except payments to be made directly to the Issuing Bank or

NYDOCS/1287812.1

Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.14, 2.15, 2.16, 2.19 and 10.3 shall be made directly to the Persons entitled thereto. The Applicable 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 of principal or interest in respect of any Loan or LC Disbursement shall, except as otherwise expressly provided herein, be made in the currency of such Loan or LC Disbursement; all other payments hereunder and under each other Loan Document shall be made in US Dollars. Any payment required to be made by any Agent hereunder shall be deemed to have been made by the time required if such Agent shall, at or before such time, have taken the necessary steps to make such payment in accordance with the regulations or operating procedures of the clearing or settlement system used by such Agent to make such payment.

(b) If at any time insufficient funds are received by the Agents from any Borrower (or from the Administrative Borrower as guarantor of the Obligations of such Borrower pursuant to Article IX) and available to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due from such Borrower hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due from such Borrower 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 from such Borrower 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 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 any Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Administrative Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). Each Borrower consents to the foregoing and

NYDOCS/1287812.1

agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Borrower’s rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

(d) Unless an Agent shall have received notice from a Borrower prior to the date on which any payment is due to such Agent for the account of the Lenders or the Issuing Bank hereunder that such Borrower will not make such payment, such Agent may assume that such Borrower has 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 such Borrower has 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 such 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 Agent, at a rate determined by the 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 2.4(c), 2.5(d) or (e), 2.6(b), 2.17(d) or 10.3(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.

SECTION 2.18. Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.14 or 2.19 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 2.16 or if any Borrower is required to pay any additional interest to any Lender pursuant to Section 2.19, 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 2.14, 2.16 or 2.19 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. Each Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If (i) any Lender requests compensation under Section 2.14 or 2.19, (ii) 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 2.16, (iii) any Loan Party is required to pay any additional interest to any Lender pursuant to Section 2.19 or (iv) any Lender defaults in its obligation to fund Loans hereunder, then the applicable Borrower may, at its 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 10.4), all its

NYDOCS/1287812.1

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 (x) such Borrower 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, (y) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and funded 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 such Borrower (in the case of all other amounts) and (z) in the case of any such assignment resulting from a claim for compensation under Section 2.14 or 2.19 or payments required to be made pursuant to Section 2.16 or additional interest required pursuant to Section 2.19, 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, within five Business Days after being notified that the applicable Borrower proposes to require a Lender to make such assignment and delegation hereunder, as a result of a waiver by such Lender or otherwise, the circumstances entitling such Borrower to require such assignment and delegation cease to apply.

SECTION 2.19. Foreign Subsidiary Costs. (a)If the cost to any Lender of making or maintaining any Loan to any Borrower is increased (or the amount of any sum received or receivable by any Lender (or its applicable lending office) is reduced) by an amount deemed in good faith by such Lender to be material, due to a Change in Law and by reason of the fact that such Borrower is incorporated in, or conducts business in, a jurisdiction other than the United States of America or Canada, such Borrower shall indemnify such Lender for such increased cost or reduction within 30 days after demand by such Lender (with a copy to the Administrative Agent). A certificate of such Lender claiming compensation under this paragraph and setting forth the additional amount or amounts to be paid to it hereunder (and the basis for the calculation of such amount or amounts) shall be conclusive in the absence of manifest error.

(b) Each Lender will promptly notify the Administrative Borrower and the Administrative Agent of any event of which it has knowledge that will entitle such Lender to additional interest or payments pursuant to paragraph (a) above, but in any event within 45 days after such Lender obtains actual knowledge thereof; provided that (i) if any Lender fails to give such notice within 45 days after it obtains actual knowledge of such an event, such Lender shall, with respect to compensation payable pursuant to this Section in respect of any costs resulting from such event, only be entitled to payment under this Section for costs incurred from and after the date 45 days prior to the date that such Lender does give such notice and (ii) each Lender will designate a different applicable lending office, if, in the judgment of such Lender, such designation will avoid the need for, or reduce the amount of, such compensation and will not be otherwise disadvantageous to such Lender.

SECTION 2.20. Redenomination of Certain Alternative Currencies. (a)Each obligation of any party to this Agreement to make a payment denominated in the national currency unit of any member state of the European Union that adopts the Euro as its lawful currency after the Effective Date shall be redenominated into Euro at the time of such adoption (in accordance with

NYDOCS/1287812.1

the EMU Legislation). If, in relation to the currency of any such member state, the basis of accrual of interest expressed in this Agreement in respect of that currency shall be inconsistent with any convention or practice in the London interbank market for the basis of accrual of interest in respect of the Euro, such expressed basis shall be replaced by such convention or practice with effect from the date on which such member state adopts the Euro as its lawful currency; provided that if any Borrowing in the currency of such member state is outstanding immediately prior to such date, such replacement shall take effect, with respect to such Borrowing, at the end of the then current Interest Period.

(b) Each provision of this Agreement shall be subject to such reasonable changes of construction as the London Agent (in consultation with the Administrative Borrower) may from time to time specify to be appropriate to reflect the adoption of the Euro by any member state of the European Union and any relevant market conventions or practices relating to the Euro.

SECTION 2.21. Designation of US Subsidiary Borrowers and Foreign Borrowers. The Administrative Borrower may at any time and from time to time designate (a) any US Subsidiary as a US Subsidiary Borrower, or (b) any Foreign Subsidiary as a Foreign Borrower, in each case by delivery to the Administrative Agent of a Borrower Joinder Agreement executed by such Subsidiary and the Administrative Borrower and upon such delivery such Subsidiary shall for all purposes of this Agreement be a US Subsidiary Borrower or a Foreign Borrower, as the case may be, and a party to this Agreement. Any US Subsidiary Borrower and Foreign Borrower shall continue to be a Borrower and a party hereunder until the Administrative Borrower shall have executed and delivered to the Administrative Agent a Borrower Termination Agreement with respect to such Borrower, whereupon such Borrower shall cease to be a Borrower and a party hereunder. Notwithstanding the preceding sentence, (a) no Borrower Joinder Agreement shall become effective as to any US Subsidiary Borrower or any Foreign Borrower if it shall be unlawful for such Subsidiary to become a Borrower hereunder or for any Lender to make Loans to such Subsidiary as provided herein and (b) no Borrower Termination Agreement will become effective as to any US Subsidiary Borrower or any Foreign Borrower until all Loans made to such Subsidiary shall have been repaid and all amounts payable by such Subsidiary in respect of interest and/or fees (and, to the extent notified by the Administrative Agent or any Lender, any other amounts payable under this Agreement by such Subsidiary) shall have been paid in full; provided that such Borrower Termination Agreement shall be effective to terminate the right of such Subsidiary to request or receive further Borrowings under this Agreement.

SECTION 2.22. Increase in Commitments. The Administrative Borrower shall have the right upon one or more occasions by written notice to the Administrative Agent (a “Commitment Increase Notice”) to request an increase in the aggregate Commitment (the amount of increase requested on any occasion being referred to herein as the “Increase Amount”), to a maximum aggregate Commitment of $250,000,000; provided that at the time of the Commitment Increase Notice and at the time such request would become effective (i) no Default has occurred and is continuing or would exist after giving effect to such increase in the Commitment, and (ii) the Administrative Borrower will be in pro forma compliance with the covenant in Section 6.7 after giving effect to any funding in connection with such increase in the Commitment.

NYDOCS/1287812.1

The Commitment Increase Notice shall be delivered by the Administrative Agent to the Lenders and shall specify a time period selected by the Administrative Borrower within which each Lender is requested to respond to such Commitment Increase Notice (which shall in no event be less than ten Business Days from the date of delivery of such Commitment Increase Notice to the Lenders). Each Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its Commitment and, if so, the amount of such increase. Any such Lender not responding within such time period shall be deemed to have declined to increase its Commitment. The Administrative Agent shall notify the Administrative Borrower and each Lender of such other Lender’s responses to each request made hereunder. After the expiration of the time period set forth in the Commitment Increase Notice or receipt by the Administrative Agent of responses to the Commitment Increase Notice from each of the Lenders, then the Administrative Borrower may, to achieve the full amount of the requested increase in the Commitments, invite one or more other Persons (other than individuals) (an “Additional Lender”) that have agreed to provide all or any portion of the Increase Amount and that are acceptable to each of the Administrative Agent, Swingline Lender and Issuing Bank (such consent not to be unreasonably withheld) (it being agreed that any Lender as of the date of the Commitment Increase Notice would be acceptable) may be admitted as a Lender party to this Agreement in accordance with the provisions of Section 10.4(e). None of the Administrative Agent, Lead Arranger or any other Lender shall have any obligation or other commitment to provide all or any portion of the Increase Amount.

Any such increase in the Commitment shall become effective upon written notice by the Administrative Agent (which shall be promptly delivered by the Administrative Agent) to the Administrative Borrower and the Lenders specifying the effective date of such increase in Commitment, together with a revised Schedule 2.1 stating the new Commitment, and, in respect thereof, the Commitment of each Additional Lender, the respective continuing Commitment of the other Lenders and the new Revolving Credit Exposure of the Lenders.

Upon the effective date of the increased Commitment, each Additional Lender shall make all (if any) such payments to the Administrative Agent for distribution to the other Lenders as may be necessary to result in the respective Revolving Loans held by such Additional Lender and the other Lenders being equal to such applicable Lender’s Applicable Percentage of the aggregate principal amount of all Revolving Loans outstanding as of such date. The Administrative Borrower hereby agrees that any Additional Lender so paying any such amount to the other Lenders pursuant to the preceding sentence shall be entitled to all the rights of a Lender having Commitments hereunder in respect of such amounts, that such payments to such other Lenders shall thereafter constitute Revolving Loans made by such Additional Lender hereunder and that such Additional Lender may exercise all of its right of payment with respect to such amounts as fully as if such Additional Lender had initially advanced to the Administrative Borrower directly the amount of such payments. If any such adjustment payments pursuant to the preceding sentences of this Section 2.22 are made by an Additional Lender to other Lenders at a time other than the end of an Interest Period in the case of all or any portion of Revolving Loans constituting Eurocurrency Loans, CDOR Rate Loans or EURIBOR Loans, the Administrative Borrower shall pay to each of the Lenders receiving any such payment, at the time that such payment is made pursuant to this Section 2.22, the amount that would be required to be paid by the Administrative Borrower pursuant to Section 2.15 had such payments been made directly by the Administrative Borrower.

ARTICLE VIII.

THE AGENTS

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Agents as their agents and authorizes the Agent to take such actions on its behalf and to exercise such powers as are delegated to the Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

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

The Agents shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Agents shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Agents shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Agents are required to exercise in writing as directed by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.2), and (c) except as expressly set forth herein, the Agents shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Administrative Borrower or any of its Subsidiaries that is communicated to or obtained by them or any of their Affiliates in any capacity. The Agents shall not be liable for any action taken or not taken by them with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.2) or in the absence of their own gross negligence or willful misconduct. Each Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to such Agent by the Administrative Borrower or a Lender, and the Agents shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any

NYDOCS/1287812.1

certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to such Agent.

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

Each 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 it. The London Agent shall have no duties or rights hereunder until the Administrative Borrower provides the London Agent with a Borrowing Request and requests a Borrowing in an Alternative Currency other than Canadian Dollars. At such time, the London Agent shall be appointed as an Agent by the Administrative Agent and the London Agent shall become party to this Agreement as an Agent. Thereafter, the London Agent shall be an Agent hereunder. Each 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 activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Agent as provided in this paragraph, each Agent may resign at any time by notifying the other Agents, the Lenders, the Issuing Bank and the Administrative Borrower. Upon any such resignation, the Required Lenders (in the case of a resignation by the Administrative Agent) or the Administrative Agent (in the case of a resignation by any other Agent) shall have the right, in consultation with the Administrative Borrower, to appoint a successor. If no successor Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such Person. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Administrative Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Administrative Borrower and such successor. After an Agent’s resignation hereunder, the provisions of this Article and Section 10.3 shall continue in effect for the benefit of such retiring 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 Agent.

NYDOCS/1287812.1

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

The Lead Arranger shall have no duties, responsibilities or obligations to, no authority to act for, any other party to this Agreement by virtue of its status as Lead Arranger hereunder.

ARTICLE IX.

GUARANTEE

In order to induce the Lenders to extend credit to the other Borrowers hereunder, the Administrative Borrower hereby irrevocably and unconditionally guarantees, as a primary obligor and not merely as a surety, the payment when and as due of the Obligations of such other Borrowers. The Administrative Borrower further agrees that the due and punctual payment of such Obligations may be extended or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its guarantee hereunder notwithstanding any such extension or renewal of any such Obligation.

The Administrative Borrower waives presentment to, demand of payment from and protest to any Borrower of any of the Obligations, and also waives notice of acceptance of its obligations and notice of protest for nonpayment. The obligations of the Administrative Borrower hereunder shall not be affected by (a) the failure of any Agent or Lender to assert any claim or demand or to enforce any right or remedy against any Loan Party under the provisions of this Agreement, any other Loan Document or otherwise, (b) any extension or renewal of any of the Obligations, (c) any rescission, waiver, amendment or modification of, or release from, any of the terms or provisions of this Agreement, or any other Loan Document or agreement, (d) any default, failure or delay, willful or otherwise, in the performance of any of the Obligations or (e) any other act, omission or delay to do any other act which may or might in any manner or to any extent vary the risk of the Administrative Borrower or otherwise operate as a discharge of a guarantor as a matter of law or equity or which would impair or eliminate any right of the Administrative Borrower to subrogation.

The Administrative Borrower further agrees that its agreement hereunder constitutes a guarantee of payment when due (whether or not any bankruptcy or similar proceeding shall have stayed the accrual or collection of any of the Obligations or operated as a discharge thereof) and not merely of collection, and waives any right to require that any resort be had by any Agent or Lender to any balance of any deposit account or credit on the books of any Agent or Lender in favor of any Borrower or any other Person.

The obligations of the Administrative Borrower hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than the indefeasible payment in full of all the Obligations owned by the Administrative Borrower to the Agents, the Issuing Bank and the Lenders), and shall not be subject to any defense or set-off, counterclaim,

NYDOCS/1287812.1

recoupment or termination whatsoever, by reason of the invalidity, illegality or unenforceability of any of the Obligations, any impossibility in the performance of any of the Obligations or otherwise (other than for the indefeasible payment in full of all the Obligations owed by the Administrative Borrower to the Agents, the Issuing Bank and the Lenders).

The Administrative Borrower further agrees that its obligations hereunder shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by any Agent or Lender upon the bankruptcy or reorganization of any Borrower or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Agent or Lender may have at law or in equity against the Administrative Borrower by virtue hereof, upon the failure of any other Borrower to pay any Obligation when and as the same shall become due, whether at maturity, by acceleration, after notice of prepayment or otherwise, the Administrative Borrower hereby promises to and will, upon receipt of written demand by any Agent or Lender, forthwith pay, or cause to be paid, to the Applicable Agent or Lender in cash an amount equal to the unpaid principal amount of such Obligations then due, together with accrued and unpaid interest thereon. The Administrative Borrower further agrees that if payment in respect of any Obligation shall be due in a currency other than US Dollars and/or at a place of payment other than New York and if, by reason of any Change in Law, disruption of currency or foreign exchange markets, war or civil disturbance or other event, payment of such Obligation in such currency or at such place of payment shall be impossible or, in the reasonable judgment of any Agent or Lender, not consistent with the protection of its rights or interests, then, at the election of the Administrative Agent, the Administrative Borrower shall make payment of such Obligation in US Dollars (based upon the applicable Exchange Rate in effect on the date of payment) and/or in New York, and shall indemnify each Agent and Lender against any losses or reasonable out-of-pocket expenses that it shall sustain as a result of such alternative payment.

Upon payment by the Administrative Borrower of any sums as provided above, all rights of the Administrative Borrower against any Borrower arising as a result thereof by way of right of subrogation or otherwise shall in all respects be subordinated and junior in right of payment to the prior indefeasible payment in full of all the Obligations owed by such Borrower to the Agents, the Issuing Bank and the Lenders.

Nothing shall discharge or satisfy the liability of the Administrative Borrower hereunder except the full performance and payment of the Obligations.

(c) Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto.

SECTION 10.2. Waivers; Amendments. (a) No failure or delay by any 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 Agents, 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 any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether any 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 Administrative Borrower and the Required Lenders or by the Administrative Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any provisions of Article IX without the written consent of each Lender or (vi) change any of the provisions of this Section or the definition of “Required Lenders”, “Alternative Currency” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of any Agent, the Issuing Bank or the Swingline Lender hereunder without the prior written consent of such Agent, the Issuing Bank or the Swingline Lender, as the case may be.

SECTION 10.3. Expenses; Indemnity; Damage Waiver. (a) The Administrative Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Agents and their Affiliates, including the reasonable fees, charges and disbursements of counsel for the Agents, in connection with the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated

NYDOCS/1287812.1

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 Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Agents, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Agents, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights after a Default in connection with this Agreement, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder after a Default, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) The Administrative Borrower shall indemnify the Agents, 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 Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Administrative Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Administrative Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

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

(d) To the extent permitted by applicable law, the Administrative Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or

NYDOCS/1287812.1

any agreement or instrument contemplated hereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable promptly after written demand therefor.

SECTION 10.4. Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Loan Parties may not assign or otherwise transfer any of their rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by a Loan Party 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 Letter of Credit), 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 Agents, 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 Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Administrative Borrower, provided that no consent of the Administrative Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (so long as any such assignee shall maintain any loans to the Canadian Borrowers at its Canadian Lending Office before an Event of Default has occurred and is continuing) or, if an Event of Default has occurred and is continuing, any other assignee; and

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

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any Class, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption

NYDOCS/1287812.1

with respect to such assignment is delivered to the Administrative Agent) shall not be less than US$5,000,000 unless each of the Administrative Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Administrative Borrower shall be required if an Event of Default has occurred and is continuing;

(B) 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;

(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 US$3,500 (which fee shall be paid by the assigning Lender);

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in which the assignee designates one or more credit contacts to whom all syndicate-level information (which may contain material non-public information about the Administrative Borrower, the other Loan Parties and their related parties or their respective securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable laws, including Federal and state securities laws;

(E) any Foreign Lender shall have delivered tax certificates described in Section 2.16, which indicate that such Foreign Lender is exempt from any withholding tax under the law of the jurisdiction in which the Administrative Borrower is located, or any treaty to which such jurisdiction is a party; and

(F) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire in which the assignee designates one or more credit contacts to whom all syndicate-level information (which may contain material non-public information about the Administrative Borrower, the other Loan Parties and their related parties or their respective securities) will be made available and who may receive such information in accordance with the assignee’s compliance procedures and applicable laws, including Federal and state securities laws.

For the purposes of this Section 10.4(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

NYDOCS/1287812.1

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 Sections 2.14, 2.15, 2.16, 2.19 and 10.3). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.4 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 Administrative Borrower, 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 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 Administrative Borrower, 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 Administrative Borrower, 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, any certificates required by Section 2.16(e), 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 Sections 2.4(c), 2.5(d) or (e), 2.6(b), 2.17(d) or 10.3(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

NYDOCS/1287812.1

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 Administrative Borrower, 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 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 Administrative Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 10.2(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Administrative Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.14, 2.15, 2.16 and 2.19 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.8 as though it were a Lender, provided such Participant agrees to be subject to Section 2.17(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.14, 2.16 or 2.19 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.16 unless the Administrative Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Administrative Borrower, to comply with Section 2.16(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) On one or more occasions, one or more Additional Lenders may be admitted as Lenders party to this Agreement in connection with an increase of the total Commitment pursuant to Section 2.22, subject to (i) execution and delivery by any such Additional Lender to the Administrative Agent, for recording in the Register, of an

NYDOCS/1287812.1

Instrument of Adherence substantially in the form of Exhibit H hereto (an “Instrument of Adherence”), (ii) acceptance of such Instrument of Adherence by each of the Administrative Agent and the Administrative Borrower by their respective executions thereof, and (iii) the completion of an Administrative Questionnaire by such Additional Lender promptly delivered to the Administrative Agent. Upon the satisfaction of the foregoing conditions, from and after the effective date specified in each such Instrument of Adherence, the Additional Lender shall be a Lender party hereto and have the rights and obligations of a Lender hereunder.

SECTION 10.5. Survival. All covenants, agreements, representations and warranties made by the Borrowers and the Loan Parties 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 Letters of Credit, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.14, 2.15, 2.16, 2.19 and 10.3 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 Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 10.6. 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 Agents or the Issuing Bank 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 4.1, 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 10.7. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 10.8. Right of Setoff. Subject to the provisions of Section 10.18 hereof, 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

NYDOCS/1287812.1

credit or the account of any Borrower against any of and all the obligations of any Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. Subject to the provisions of Section 10.18 hereof, the rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 10.9. 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 New York.

(b) Each party hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this 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 New York 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 any Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Administrative Borrower or its properties in the courts of any jurisdiction.

(c) Each party hereto 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 10.1. 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 10.10. 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

NYDOCS/1287812.1

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

SECTION 10.12. Confidentiality. (a) Each of the Agents, 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’ 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 Administrative Borrower and its obligations, (g) with the consent of the Administrative Borrower 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 any Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Administrative Borrower. For the purposes of this Section, “Information” means all information received from the Administrative Borrower relating to the Administrative Borrower or its business, other than any such information that is available to any Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Administrative Borrower. 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. Each of the Agents, Issuing Bank, and the Lenders agrees to use reasonable commercial efforts (if it may legally do so) to provide prior notice of any disclosure of Information pursuant to clauses (b) or (c) above.

(b) EACH LENDER ACKNOWLEDGES THAT INFORMATION AS DEFINED IN SECTION 10.12(a) FURNISHED TO IT PURSUANT TO THIS AGREEMENT MAY INCLUDE MATERIAL NON-PUBLIC INFORMATION CONCERNING THE ADMINISTRATIVE BORROWER AND ITS RELATED PARTIES OR THEIR RESPECTIVE SECURITIES, AND CONFIRMS 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, PROVINCIAL, TERRITORIAL AND STATE SECURITIES LAWS.

NYDOCS/1287812.1

(c) ALL INFORMATION, INCLUDING REQUESTS FOR WAIVERS AND AMENDMENTS, FURNISHED BY THE ADMINISTRATIVE BORROWER OR THE AGENTS PURSUANT TO, OR IN THE COURSE OF ADMINISTERING, THIS AGREEMENT WILL BE SYNDICATE-LEVEL INFORMATION, WHICH MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION ABOUT THE ADMINISTRATIVE BORROWER, THE OTHER LOAN PARTIES AND THEIR RELATED PARTIES OR THEIR RESPECTIVE SECURITIES. ACCORDINGLY, EACH LENDER REPRESENTS TO THE ADMINISTRATIVE BORROWER AND EACH AGENT THAT IT HAS IDENTIFIED IN ITS ADMINISTRATIVE QUESTIONNAIRE A CREDIT CONTACT WHO MAY RECEIVE INFORMATION THAT MAY CONTAIN MATERIAL NON-PUBLIC INFORMATION IN ACCORDANCE WITH ITS COMPLIANCE PROCEDURES AND APPLICABLE LAW.

SECTION 10.13. 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 10.14. Conversion of Currencies. (a) If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum owing hereunder in one currency into another currency, each party hereto agrees, to the fullest extent that it may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures in the relevant jurisdiction the first currency could be purchased with such other currency on the Business Day immediately preceding the day on which final judgment is given.

(b) The obligations of each party hereto in respect of any sum due to any other party hereto or any holder of the obligations owing hereunder (the “Applicable Creditor”) shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than the currency in which such sum is stated to be due hereunder (the “Agreement Currency”), be discharged only to the extent that, on the Business Day following receipt by the Applicable Creditor of any sum adjudged to be so due in the Judgment Currency, the Applicable Creditor may in accordance with normal banking procedures in the relevant jurisdiction purchase the Agreement Currency with the Judgment Currency; if the amount of the Agreement Currency so purchased is less than the sum originally due to the Applicable Creditor in the Agreement Currency, the Administrative Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Applicable Creditor against such loss. The obligations of each party hereto contained in

NYDOCS/1287812.1

this Section 10.14 shall survive the termination of this Agreement and the payment of all other amounts owing hereunder.

SECTION 10.15. Releases of Guarantees. (a) In the event of a disposition of all the Equity Interests in a Subsidiary Guarantor to a Person other than the Administrative Borrower or an Affiliate of the Administrative Borrower in a transaction not prohibited by any covenant contained in this Agreement, the Administrative Agent is hereby directed and authorized to take such action and to execute such documents as the Administrative Borrower may reasonably request, at the Administrative Borrower’s sole expense, to evidence or effect the release of the Guarantee by such Subsidiary Guarantor under the Subsidiary Guaranty Agreement.

(b) Without limiting the provisions of Section 10.5, the Administrative Borrower shall reimburse the Administrative Agent for all costs and expenses, including attorney’s fees and disbursements, incurred by it in connection with any action contemplated by this Section 10.15.

SECTION 10.16. 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 each of the Loan Parties that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Loan Parties, which information includes the name and address of each Loan Party and other information that will allow such Lender to identify such Loan Parties in accordance with the Act.

SECTION 10.17. No Fiduciary Duty. The Administrative Borrower, on behalf of itself and the Subsidiaries, agrees that in connection with all aspects of the transactions contemplated hereby and any communications in connection therewith, the Administrative Borrower, the Subsidiaries and their Affiliates, on the one hand, and the Agents, the Issuing Bank, the Lenders and their Affiliates, on the other hand, will have a business relationship that does not create, by implication or otherwise, any fiduciary duty on the part of the Agents, the Issuing Bank, the Lenders or their Affiliates, and no such duty will be deemed to have arisen in connection with any such transactions or communications.

SECTION 10.18. Liability for Obligations. Notwithstanding anything to the contrary contained in this Agreement or in the other Loan Documents to the contrary, the parties agree that: (a) the Foreign Subsidiaries shall not be liable for any obligation of the Administrative Borrower or any US Subsidiary Borrower arising under or with respect to any of the Loan Documents; (b) each Foreign Borrower shall be severally liable only for the obligations of such Foreign Borrower; and (c) no Agent or Lender, or any Affiliate thereof, may set-off or apply any deposits of a Foreign Subsidiary or any other obligations at the time owing to or for the credit of the account of any Foreign Subsidiary by such Agent, Lender of Affiliate thereof, against any or all of the obligations of the Administrative Borrower or any US Subsidiary Borrower.

AMENDED AND RESTATED SUBSIDIARY GUARANTEE AGREEMENT

AMENDED AND RESTATED SUBSIDIARY GUARANTEE AGREEMENT (this “Guaranty”) dated as of March 30, 2007 made by the undersigned (the “Guarantors”) in favor of JPMorgan Chase Bank, National Association, as administrative agent (together with its successor(s) thereto, in such capacity, the “Administrative Agent”), the Lenders and each other Agent under the Amended and Restated Credit Agreement, dated as of the date hereof (as amended, supplemented or otherwise modified from time to time, the “Credit Agreement”), among IDEXX Laboratories, Inc., a Delaware corporation (the “Administrative Borrower”), each Guarantor, IDEXX Laboratories Canada Corporation, a company formed under the laws of Canada (“IDEXX Canada;” together with the Administrative Borrower, each Guarantor and the other persons who are or hereafter are designated as a Borrower pursuant to Section 2.21 thereto, the “Borrowers”), the Lenders party thereto, the Administrative Agent and JPMorgan Chase Bank, National Association, Toronto Branch, as the Toronto Agent (collectively with the Administrative Agent, the “Agents”). Capitalized terms not otherwise defined herein shall have the meanings ascribed to such terms in the Credit Agreement.

PRELIMINARY STATEMENTS:

The Agents and the Lenders have entered into certain arrangements with the Borrowers as more fully set forth in the Credit Agreement, providing for credit extensions or financial accommodation to the Borrowers, including but not limited to the making of loans, advances or overdrafts, issuance or confirmation of letters of credit, guaranties or indemnities (collectively, the “Facilities”) (any writing evidencing or supporting the Facilities, including but not limited to this Guaranty, as such writing may be amended, modified or supplemented from time to time, a “Facility Document”). The Administrative Borrower owns a substantial amount of the stock or other ownership interests of the Guarantors and is financially interested in its affairs.

Certain of the Guarantors entered into a Credit Agreement dated as of January 25, 2007 (as heretofore amended, the “Former Credit Agreement”) with the Administrative Agent and the financial institutions party thereto pursuant to which such financial institutions, subject to the terms and conditions contained therein, provided certain financial accommodations to the Borrowers. The Former Credit Agreement has been amended and restated in its entirety by the Credit Agreement as set forth therein and shall remain in full force and effect only as set forth therein.

Certain of the Guarantors entered into a Guaranty dated as of January 25, 2007 (as heretofore amended, the “Former Guaranty”) in favor of the Administrative Agent. Each Guarantor and the Administrative Agent now wish to amend and restate the Former Guaranty for the benefit of the Administrative Agent as herein provided, which shall supersede the Former Guaranty.

THEREFORE, in order to induce the Agents and the Lenders to extend credit or give financial accommodation under the Facilities, the Guarantors agree as follows:

Exhibit C - Form of Subsidiary Guarantee Agreement

NYDOCS/1287812.1

Section 1. Guaranty of Payment. Each Guarantor unconditionally and irrevocably guarantees to each of the Agents, in their individual capacities, and the Lenders, the punctual payment of all sums now owing or which may in the future be owing by the Borrowers under the Facilities, when the same are due and payable, whether on demand, at stated maturity, by acceleration or otherwise, and whether for principal, interest, fees, expenses, indemnification or otherwise (all of the foregoing sums being the “Liabilities”). The Liabilities include, without limitation, interest accruing after the commencement of a proceeding under bankruptcy, insolvency or similar laws of any jurisdiction at the rate or rates provided in the Facility Documents. This Guaranty is a guaranty of payment and not of collection only. The Agents and the Lenders shall not be required to exhaust any right or remedy or take any action against the Borrowers or any other person or entity or any collateral. Each Guarantor agrees that, as between the Guarantors, the Agents and the Lenders, the Liabilities may be declared to be due and payable for the purposes of this Guaranty notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards the Borrowers and that in the event of a declaration or attempted declaration, the Liabilities shall immediately become due and payable by such Guarantor for the purposes of this Guaranty.

Section 2. Guaranty Absolute. Each Guarantor guarantees that the Liabilities shall be paid strictly in accordance with the terms of the Facilities. The liability of each Guarantor under this Guaranty is absolute and unconditional irrespective of: (a) any change in the time, manner or place of payment of, or in any other term of, all or any of the Facility Documents or Liabilities, or any other amendment or waiver of or any consent to departure from any of the terms of any Facility Document or Liability, including any increase or decrease in the rate of interest thereon; (b) any release or amendment or waiver of, or consent to departure from, any other guaranty or support document, or any exchange, release or non-perfection of any collateral, for all or any of the Facility Documents or Liabilities; (c) any present or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any Facility Document or Liability; (d) without being limited by the foregoing, any lack of validity or enforceability of any Facility Document or Liability; and (e) any other setoff, defense or counterclaim whatsoever (in any case, whether based on contract, tort or any other theory) with respect to the Facility Documents or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or discharge of, the Borrowers.

Section 3. Guaranty Irrevocable. This Guaranty is a continuing guaranty of the payment of all Liabilities now or hereafter existing under the Facilities and shall remain in full force and effect until payment in full of all Liabilities and until all the Commitments have been terminated.

Section 4. Reinstatement. This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Liabilities is rescinded or must otherwise be returned by the Administrative Agent on the insolvency, bankruptcy or reorganization of the Borrowers or otherwise, all as though the payment had not been made.

Section 5. Subrogation. No Guarantor shall exercise any rights which it may acquire by way of subrogation, by any payment made under this Guaranty or otherwise, until all the Liabilities have been paid in full and the Facilities are no longer in effect. If any amount is paid

Exhibit C - Form of Subsidiary Guarantee Agreement

NYDOCS/1287812.1

to any Guarantor on account of subrogation rights under this Guaranty at any time when all the Liabilities have not been paid in full, the amount shall be held in trust for the benefit of the Agents and the Lenders and shall be promptly paid to the Administrative Agent to be credited and applied to the Liabilities, whether matured or unmatured or absolute or contingent, in accordance with the terms of the Facilities. If any Guarantor makes payment to the Administrative Agent of all or any part of the Liabilities and all the Liabilities are paid in full and the Facilities are no longer in effect, the Administrative Agent shall, at such Guarantor’s request, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Liabilities resulting from the payment.

Section 6. Subordination. Without limiting each Agents’ rights in their individual capacities as agents, and the Lenders’ rights under any other agreement, any liabilities owed by the Borrowers to any Guarantor in connection with any extension of credit or financial accommodation by any Guarantor to or for the account of the Borrowers, including but not limited to interest accruing at the agreed contract rate after the commencement of a bankruptcy or similar proceeding, are hereby subordinated to the Liabilities, and such liabilities of the Borrowers to such Guarantor, if the Administrative Agent so requests, after the occurrence and during the continuation of a Default or Event of Default, shall be collected, enforced and received by such Guarantor as trustee for the Agents in their individual capacities as agents and the Lenders and shall be paid over to the Administrative Agent for itself and for the other Agents in their individual capacities as agents and the Lenders on account of the Liabilities but without reducing or affecting in any manner the liability of such Guarantor under the other provisions of this Guaranty.

Section 7. Payments Generally. All payments by each Guarantor shall be made in the manner, at the place and in the currency (the “Payment Currency”) required by the Facility Documents; provided, that (if the Payment Currency is other than US Dollars) such Guarantor may, at its option (or, if for any reason whatsoever such Guarantor is unable to effect payments in the foregoing manner, such Guarantor shall be obligated to) pay to the Applicable Agent at its principal office the US Dollar Equivalent computed at the selling rate of the Applicable Agent or a selling rate chosen in good faith by the Applicable Agent, most recently in effect on or prior to the date the Liability becomes due, for cable transfers of the Payment Currency to the place where the Liability is payable. In any case in which such Guarantor makes or is obligated to make payment in US Dollars, such Guarantor shall hold the Agents harmless from any loss incurred by such Agents arising from any change in the value of US Dollars in relation to the Payment Currency between the date the Liability becomes due and the date each such Agent is actually able, following the conversion of the US Dollars paid by such Guarantor into the Payment Currency and remittance of such Payment Currency to the place where such Liability is payable, to apply such Payment Currency to such Liability.

Section 8. Certain Taxes. Each Guarantor further agrees that all payments to be made hereunder shall be made without setoff or counterclaim and free and clear of, and without deduction for, any Indemnified Taxes or Other Taxes (collectively, “Taxes”).

MANDATORY COSTS RATE

1. The Mandatory Costs Rate is an addition to the interest rate to compensate Lenders for the cost of compliance with (a) the requirements of the Bank of England and/or the Financial Services Authority (or, in either case, any other authority which replaces all or any of its functions) or (b) the requirements of the European Central Bank.

2. On the first day of each Interest Period (or as soon as possible thereafter) the London Agent shall calculate a rate (the “Additional Costs Rate”), expressed as a percentage, for each Lender, in accordance with the paragraphs set out below. The Mandatory Costs Rate will be calculated by the London Agent as a weighted average of the Lenders’ Additional Costs Rates (weighted in proportion to the percentage participation of each Lender in the applicable Borrowing) and will be expressed as a percentage rate per annum. The London Agent will, at the request of the Administrative Borrower or any Lender, deliver to the Administrative Borrower or such Lender, as the case may be, a statement setting forth the calculation of the Mandatory Cost Rate.

3. The Additional Costs Rate for any Lender lending from a lending office located in a Participating Member State will be the percentage notified by that Lender to the London Agent. This percentage will be certified by that Lender in its notice to the London Agent to be its reasonable determination of the cost (expressed as a percentage of that Lender’s participation in all Loans made from such lending office) of complying with the minimum reserve requirements of the European Central Bank in respect of Loans made from such lending office.

4. The Additional Costs Rate for any Lender lending from a lending office in the United Kingdom will be calculated by the London Agent as follows:

(a) with respect to any Loan denominated in Sterling:

percent per annum

(b)	with respect to any Loan denominated in any currency (other than Sterling):

percent per annum.

Where:

“A” means the percentage of Eligible Liabilities (assuming these to be in excess of any stated minimum) which that Lender is from time to time required to maintain as an interest free cash ratio deposit with the Bank of England to comply with cash ratio requirements.

Exhibit D - Mandatory Costs Rate

NYDOCS/1287812.1

“B” means the percentage rate of interest (excluding the Applicable Margin and the Mandatory Costs Rate and the additional rate of interest specified in Section 2.12(c)) payable for the applicable Interest Period on the Loan.

“C” means the percentage (if any) of Eligible Liabilities which that Lender is required from time to time to maintain as interest bearing Special Deposits with the Bank of England.

“D” means the percentage rate per annum payable by the Bank of England to the London Agent on interest bearing Special Deposits.

“E” is designed to compensate Lenders for amounts payable under the Fees Rules and is calculated by the London Agent as being the average of the most recent rates of charge supplied by the Lenders to the London Agent pursuant to paragraph 7 below and expressed in Sterling per £1,000,000.

5. For the purposes of this Schedule:

(a) “Eligible Liabilities” and “Special Deposits” have the meanings given to them from time to time under or pursuant to the Bank of England Act 1998 or (as may be appropriate) by the Bank of England.

(b) “Fees Rules” means the rules on periodic fees contained in the Financial Services Authority Supervision Manual or such other law or regulation as may be in force from time to time in respect of the payment of fees for the acceptance of deposits.

(c) “Fee Tariffs” means the fee tariffs specified in the Fees Rules under the activity group A.1 Deposit acceptors (ignoring any minimum fee or zero rated fee required pursuant to the Fees Rules but taking into account any applicable discount rate).

(d) “Participating Member State” means any member state of the European Communities that adopts or has adopted the Euro as its lawful currency in accordance with legislation of the European Community relating to Economic and Monetary Union.

(e) “Tariff Base” has the meaning given to it in, and will be calculated in accordance with, the Fees Rules.

6. In application of the above formulae, A, B, C and D will be included in the formulae as percentages (i.e. 5% will be included in the formula as 5 and not as 0.05). A negative result obtained by subtracting D from B shall be taken as zero. The resulting figures shall be rounded to four decimal places.

7. If requested by the London Agent or the Administrative Borrower, each Lender with a lending office located in the United Kingdom or a Participating Member State shall, as soon as practicable after publication by the Financial Services Authority, supply to the London Agent and the Administrative Borrower, the rate of charge payable by such Lender to the Financial Services Authority pursuant to the Fees Rules in respect of the relevant financial year of the

Exhibit D -Mandatory Costs Rate

NYDOCS/1287812.1

Financial Services Authority (calculated for this purpose by such Lender as being the average of the Fee Tariffs applicable to such Lender for that financial year) and expressed in Sterling per £1,000,000 of the Tariff Base of such Lender.

8. Each Lender shall supply any information required by the London Agent for the purpose of calculating its Additional Costs Rate. In particular, but without limitation, each Lender shall supply the following information on or prior to the date on which it becomes a Lender:

(a) the jurisdiction of its applicable lending office; and

(b) any other information that the London Agent may reasonably require for such purpose.

Each Lender shall promptly notify the London Agent of any change to the information provided by it pursuant to this paragraph.

9. The percentages of each Lender for the purpose of A and C above and the rates of charge of each Lender for the purpose of E above shall be determined by the London Agent based upon the information supplied to it pursuant to paragraphs 7 and 8 above and on the assumption that, unless a Lender notifies the London Agent to the contrary, each Lender’s obligations in relation to cash ratio deposits and Special Deposits are the same as those of a typical bank from its jurisdiction of incorporation with a lending office in the same jurisdiction as its applicable lending office.

10. The London Agent shall have no liability to any person if such determination results in an Additional Costs Rate which over or under compensates any Lender and shall be entitled to assume that the information provided by any Lender or Administrative Agent pursuant to paragraphs 3, 7 and 8 above is true and correct in all respects.

11. The London Agent shall distribute the additional amounts received as a result of the Mandatory Costs Rate to the Lenders on the basis of the Additional Costs Rate for each Lender based on the information provided by each Lender and the Administrative Agent pursuant to paragraphs 3, 7 and 8 above.

12. Any determination by the London Agent pursuant to this Schedule in relation to a formula, the Mandatory Costs Rate, an Additional Costs Rate or any amount payable to a Lender shall, in the absence of manifest error, be conclusive and binding.

13. The London Agent may from time to time, after consultation with the Administrative Borrower and the Lenders, determine and notify to all parties any amendments which are required to be made to this Schedule in order to comply with any change in law, regulation or any requirements from time to time imposed by the Bank of England, the Financial Services Authority or the European Central Bank (or, in any case, any other authority which replaces all or any of its functions) and any such determination shall, in the absence of manifest error, be conclusive and binding.
