SECTION 1.02 Classification of Loans and Borrowings. For purposes of this Agreement, Loans may be classified and referred to by Type (e.g., a “Eurodollar Loan” or a “Eurodollar Revolving Loan”). Borrowings also may be classified and referred to by Type (e.g., a “Eurodollar Borrowing” or a “Eurodollar Revolving Borrowing”).

SECTION 1.03 Terms Generally. The definitions of terms herein shall apply equally to the singular and plural forms of the terms defined. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The words “include”, “includes” and “including” shall be deemed to be followed by the phrase “without limitation”.

References to quarters and months with respect to compliance with financial covenants and financial reporting obligations of the Domestic Borrower shall be fiscal quarters and fiscal months, except where otherwise indicated.

ARTICLE II

The Credits

SECTION 2.01 Commitments. (a) Subject to the terms and conditions set forth herein, each Lender agrees to make Revolving Loans to a Borrower from time to time during the Availability Period in an aggregate principal amount up to such Lender’s Revolving Loan Commitment. Within the foregoing limits and subject to the terms and conditions set forth herein, each Borrower may borrow, prepay and reborrow Revolving Loans.

(b) Revolving Loans, subject to the limitations in Section 2.01(c), below, may, at the option of the Domestic Borrower, be requested in an aggregate amount of not more than $75,000,000 or an Equivalent Amount in an Alternative Currency calculated as of the date such Loans are requested (each a “Domestic Revolving Loan”).

(c) Revolving Loans may, at the option of the Foreign Borrower, be requested in an aggregate amount of not more than $60,000,000 or an Equivalent Amount in an Alternative Currency calculated as of the date such Loans are requested (each a “Foreign Revolving Loan”);

provided, the aggregate principal amount of all Foreign Revolving Loans and all Domestic Revolving Loans, including the total LC Exposure at any time outstanding, shall not exceed the total of all of the Lenders’ Revolving Loan Commitments.

SECTION 2.02 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 Revolving Loan 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 Revolving Loan 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 2.12, for each Borrowing requested in Dollars the interest rate shall be based on the Alternative Base Rate or the Adjusted LIBO Rate as a Borrower may request in accordance herewith. For each Borrowing requested in an Alternative Currency the interest rate shall be based on the Adjusted LIBO Rate. Each Lender at its option may make any Eurodollar Loan or Alternative Currency Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of such Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000 (or, as applicable, an integral multiple of €750,000 and not less than €750,000, or an integral multiple of £500,000 and not less than £500,000). At the time that each ABR Revolving Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000; provided that an ABR Revolving Borrowing may be in an aggregate amount that is equal to (i) the entire unused

balance of the total Revolving Loan Commitments or that (ii) is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.04(e). 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 ten (10) Eurodollar Borrowings.

(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 Revolving Credit Termination Date.

SECTION 2.03 Requests for Borrowings. To request a Revolving Borrowing, either Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 1:00 p.m., Eastern time, three (3) Business Days before the date of the proposed Borrowing, (b) in the case of an ABR Borrowing, not later than 12:00 noon, Eastern time, on the date of the proposed Borrowing or (c) in the case of any Alternative Currency Borrowing, not later than 1:00 p.m., Eastern time three (3) Business Days before the Borrowing Date. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery, telecopy, or scanned copy sent by email to the Administrative Agent of a written Borrowing Request substantially in the form of Exhibit 2.03. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i) the aggregate amount of the requested Borrowing;

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

(iii) whether such Borrowing is to be an ABR Borrowing, a Eurodollar Borrowing or an Alternative Currency Borrowing, in which case such Borrower shall designate an Alternative Currency;

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

(v) the location and number of such Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.05.

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

SECTION 2.04 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, either Borrower may request the issuance of Letters of Credit in Dollars or in Alternative Currency for

its own account or the account of any of its Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the Issuing Lender, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by either Borrower to, or entered into by such Borrower with, the Issuing Lender 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), either Borrower shall hand deliver or telecopy (or transmit by scanned copy sent by email, if arrangements for doing so have been approved by the Issuing Lender) to the Issuing Lender and the Administrative Agent (three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section) the amount of such Letter of Credit, whether such Letter of Credit shall be denominated in Dollars or an Alternative Currency (and if so, which Alternative Currency), 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 Lender, such Borrower also shall submit a letter of credit application on the Issuing Lender’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 such 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 $35,000,000 and (ii) the total Revolving Credit Exposures shall not exceed the total Revolving Loan Commitments. Upon the issuance, amendment, renewal or extension of each Letter of Credit by any Issuing Lender that is not the Administrative Agent, the Issuing Lender with respect thereto shall immediately notify the Administrative Agent of such issuance, amendment, renewal or extension thereof.

(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) or a date of more than one year if the Issuing Lender agrees to such later date in its sole discretion and (ii) the date that is five (5) Business Days prior to the Revolving Credit Termination Date; provided, however, that any Letter of Credit may provide for a later expiration date if, ninety (90) days prior to the Revolving Credit Termination Date (or simultaneously with the issuance (or, if applicable, the renewal) thereof if issued after the date that is ninety (90) days prior to such date), such Borrower pledges to the Issuing Lender in a manner reasonably satisfactory to it, funds in an account with the Issuing Lender within the United States of America equal to 105% of the face amount of such Letter of Credit. After the Obligations are satisfied in full, any Letter of Credit with an expiration after the Revolving Credit Termination Date shall be considered issued solely by the Issuing Lender.

(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 Lender or the Lenders, the Issuing Lender hereby grants to each Lender, and each Lender hereby acquires from the Issuing Lender, 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 Lender, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Lender and not reimbursed by the applicable Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to either 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 an Event of Default or reduction or termination of the Revolving Loan Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Lender shall make any LC Disbursement in respect of a Letter of Credit issued for the account of a Borrower, such Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 3:00 p.m., Eastern time, on the date that such LC Disbursement is made, if such Borrower shall have received notice of such LC Disbursement prior to 1:00 p.m., Eastern time, on such date, or, if such notice has not been received by such Borrower prior to such time on such date, then not later than 1:00 p.m., Eastern time, (i) the Business Day that such Borrower receives such notice, if such notice is received prior to 11:00 a.m., Eastern time, on the day of receipt, or (ii) on the Business Day immediately following the day that such Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that, if such LC Disbursement is not less than $1,000,000, and no Default has occurred and is continuing, such Borrower may, subject to the conditions to borrowing set forth herein, request, in accordance with Section 2.03, that such payment, in the case of Letters of Credit issued in Dollars, be financed with an ABR Revolving Borrowing and, to the extent so financed, such Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Revolving Borrowing. If such 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 such 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 such Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Lender the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from such Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Lender or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Lender, then to such Lenders and the Issuing Lender as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Lender for any LC Disbursement (other than the funding of ABR Revolving Loans as contemplated above) shall not constitute a Loan and shall not relieve such Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. Each 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 Lender under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, each Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Lender, 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 Lender; provided that the foregoing shall not be construed to excuse the Issuing Lender from liability to a Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by each Borrower to the extent permitted by applicable law) suffered by a Borrower that are caused by the Issuing Lender’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 Lender (as finally determined by a court of competent jurisdiction), the Issuing Lender 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 Lender 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 Lender shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Lender shall promptly notify the Administrative Agent and the Borrower for whose account such Letter of Credit was issued by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Lender has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve such Borrower of its obligation to reimburse the Issuing Lender and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If the Issuing Lender shall make any LC Disbursement, then, unless the Borrower for whose account such Letter of Credit was issued 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 such Borrower reimburses such LC Disbursement (i) for Letters of Credit issued in Dollars, at the rate per annum then applicable to ABR Revolving Loans and (ii) for Letters of Credit issued in Alternative Currency, the Adjusted LIBO Rate plus the Applicable Margin; provided that, if such Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.11(d) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Lender, 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 Lender shall be for the account of such Lender to the extent of such payment.

(i) Replacement of the Issuing Lender. The Issuing Lender may be replaced at any time by written agreement among the Borrowers, the Administrative Agent, the replaced Issuing Lender and the successor Issuing Lender. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Lender. At the time any such replacement shall become effective, each Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Lender owed by such Borrower pursuant to Section 2.10(b). From and after the effective date of any such replacement, (i) the successor Issuing Lender shall have all the rights and obligations of the Issuing Lender under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Lender” shall be deemed to refer to such successor or to any previous Issuing Lender, or to such successor and all previous Issuing Lenders, as the context shall require. After the replacement of an Issuing Lender hereunder, the replaced Issuing Lender shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Lender 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 Domestic Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, or the Lenders with LC Exposure representing greater than 50% of the total LC Exposure demanding the deposit of cash collateral pursuant to this paragraph), the Domestic Borrower shall deposit in an account with the Administrative Agent within the United States of America, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash (in Dollars for any Letter of Credit issued in Dollars or in the Alternative Currency in which a Letter of Credit is issued for any Letter of Credit issued in Alternative Currencies) 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 Borrowers described in clause (h) or (i) of Section 7.01. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of each 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 Borrowers’ risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Lender 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 each Borrower for the LC Exposure at such time or, subject to the consent of Lenders with LC Exposure representing greater than 50% of the total LC Exposure, be applied to satisfy other obligations of each Borrower under this Agreement. If the Borrowers are required to provide an amount of cash collateral hereunder, such amount (to the extent not applied as aforesaid) shall be returned to the Borrowers within three (3) Business Days after all Events of Default have been cured or waived.

SECTION 2.05 Funding of Borrowings.

(a) Each Lender shall make each Eurodollar or ABR Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., Eastern time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders and shall make each Alternative Currency Loan to be made by it hereunder on the dates thereof by wire transfer of immediately available funds by 1:00 p.m., Eastern time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower that requested such Loans by promptly crediting the amounts so received, in like funds, to such account or accounts of the applicable 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 2.04(e) shall be remitted by the Administrative Agent to the Issuing Lender.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the 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 Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, plus any customary charges paid by the Administrative Agent to its correspondent bank, 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 Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of such Borrower, the interest rate applicable to such Borrowings. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

SECTION 2.06 Interest Elections.

(a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing or an Alternative Currency 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 Eurodollar Borrowing or an Alternative

Currency Borrowing, may elect Interest Periods therefor, all as provided in this Section. The applicable 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.

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

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

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

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

(iii) whether the resulting Borrowing is to be an ABR Borrowing, a Eurodollar Borrowing or an Alternative Currency Borrowing, in which case the Borrowers shall designate an Alternative Currency; and

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

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

(d) Promptly following receipt of an Interest Election Request, the Administrative 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 Eurodollar Revolving Borrowing denominated in Dollars prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR

Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies such Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing or an Alternative Currency Borrowing and (ii) unless repaid, each Eurodollar Borrowing denominated in Dollars shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.07 Termination and Reduction of Commitments.

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

(b) The Borrowers may at any time terminate or from time to time reduce the Revolving Loan Commitments; provided that (A) each reduction of the Revolving Loan Commitments shall be in an amount that is an integral multiple of $1,000,000 and not less than $1,000,000 (B) the Borrowers shall not terminate or reduce the Revolving Loan Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.09, the Revolving Credit Exposures would exceed the total Revolving Loan Commitments and (C) the aggregate principal amount of all Foreign Revolving Loans at any time outstanding, shall not exceed sixty percent (60%) of the total of all the Lenders’ Revolving Loan Commitments as such commitments are reduced pursuant to this Section 2.07.

(c) The Borrowers shall notify the Administrative Agent of any election to terminate or reduce the Revolving Loan Commitments under paragraph (b) of this Section no earlier than thirty (30) days and no later than three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrowers pursuant to this Section shall be irrevocable; provided that a notice of termination of the Revolving Loan Commitments delivered by the Domestic 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 Domestic Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Subject to the rights of the Domestic Borrower under Section 2.18, any, termination or reduction of the Revolving Loan Commitments shall be permanent. Each reduction of the Revolving Loan Commitments shall be made ratably among the Lenders in accordance with their respective Revolving Loan Commitments.

SECTION 2.08 Repayment of Loans; Evidence of Debt.

(a) Each Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan made to such Borrower on the Revolving Credit Termination Date.

(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 Type, the currency in which said Loan was made 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 the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) Repayments of any Loan or any Borrowing shall be made in the same currency in which said Loan or Borrowing was advanced by the Lenders.

(e) If at any time Administrative Agent notifies (i) the Domestic Borrower in writing that the amount of all Domestic Revolving Loans outstanding exceeds $75,000,000 or (ii) the Foreign Borrower in writing that the amount of all Foreign Revolving Loans outstanding exceeds $60,000,000, or, in either case, the Equivalent Amount in an Alternative Currency, the applicable Borrower shall, within ten (10) days of such notice, either (at the applicable Borrower’s option) repay the applicable Loans or deposit cash in an account with the Administrative Agent until the end of the applicable Interest Period, in either case, in an aggregate amount sufficient to reduce such amount outstanding as of such date of payment such that amount outstanding does not exceed Lenders’ Revolving Loan Commitments or an Equivalent Amount in an Alternative Currency.

(f) 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 manner affect the obligation of each Borrower to repay the Loans in accordance with the terms of this Agreement.

(g) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, each Borrower shall prepare, execute and deliver to such Lender a promissory note (each, a “Note”) payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) substantially in the form of Exhibit 2.08(g) hereto. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 10.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

SECTION 2.09 Prepayment of Loans.

(a) Each Borrower shall have the right at any time and from time to time to prepay any Borrowing made to such Borrower in whole or in part, subject to prior notice in accordance with paragraph (c) of this Section.

(b) Each prepayment pursuant to Section 2.09 shall be applied to reduce pro rata all Loans comprising the designated Borrowing being prepaid.

(c) Each Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 1:00 p.m., Eastern time, three (3) Business Days before the

date of prepayment, (ii) in the case of prepayment of an ABR Borrowing, not later than 1:00 p.m., Eastern time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Revolving Loan Commitments as contemplated by Section 2.07, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07. Promptly following receipt of any such notice relating to a Revolving Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.11.

SECTION 2.10 Fees.

(a) The Borrowers shall pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Commitment Fee Rate on the daily amount of the unused Revolving Loan Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which such Revolving Loan Commitment terminates; provided that, if such Lender continues to have any Revolving Credit Exposure after its Revolving Loan Commitment terminates, then such commitment fee shall continue to accrue on the daily amount of such Lender’s Revolving Credit Exposure from and including the date on which its Revolving Loan Commitment terminates to but excluding the date on which such Lender ceases to have any Revolving Credit Exposure. 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 Revolving Loan 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 Revolving Loan 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) Each Borrower shall pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit issued for the account of such Borrower, which fee shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Revolving Loan Commitment terminates and the date on which it ceases to have any LC Exposure and (ii) to the Issuing Lender a fronting fee, which shall accrue at the rate of 0.125% per annum but in no event less than $500 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 Revolving Loan Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Lender’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 (3rd) Business

Day following such last day of such months, 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 Revolving Loan Commitments terminate and any such fees accruing after the date on which the Revolving Loan Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Lender pursuant to this paragraph shall be payable within ten (10) days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) The Domestic Borrower shall pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times specified in the Fee Letter, or otherwise separately agreed upon, between the Domestic Borrower and the Administrative Agent.

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Lender, 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.

(e) Notwithstanding any provision of this Agreement to the contrary, for a period of twelve (12) months following the Effective Date, the Administrative Agent, each Issuing Lender, the Lead Arrangers, and the Lenders agree that so long as the Borrowers are in compliance with Sections 6.14, 6.15 and 6.16, the Borrowers will not be assessed any additional arrangement or upfront fees in connection with any modification of this Credit Facility; provided said request does not require an amendment to Sections 6.14, 6.15 and 6.16 or the Administrative Agent does not reasonably believe such request materially affects the rights of the Administrative Agent and the Lenders under the Loan Documents.

SECTION 2.11 Interest.

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

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

(c) The Loans comprising each Alternative Currency Loan shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin.

(d) Notwithstanding the foregoing, but subject to Section 10.13, if any principal of or interest on any Loan or any fee or other amount payable by either Borrower hereunder is not paid when due, such overdue amount shall bear interest at the Default Rate.

(e) Subject to Section 10.13, 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 Revolving Loan Commitments; provided that (i) interest accrued pursuant to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any repayment or

prepayment of any Loan (other than a prepayment of an ABR 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 Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

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

SECTION 2.12 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

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

(b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate, the LIBO Rate or the rate applicable to Alternative Currency Borrowings, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

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

SECTION 2.13 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 Issuing Lender; or

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

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or Alternative Currency Loans (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or the Issuing Lender 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 Lender hereunder (whether of principal, interest or otherwise), then each Borrower will pay to such Lender or the Issuing Lender, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Lender, as the case may be, for such additional costs incurred or reduction suffered in connection with the Loans made to, or Letters of Credit issued for the account of, such Borrower.

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

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

(d) Failure or delay on the part of any Lender or the Issuing Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Lender’s right to demand such compensation; provided that neither Borrower shall be required to compensate a Lender or the Issuing Lender 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 Lender, as the case may be, notifies the Borrowers of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Lender’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; provided, further, that no Lender shall seek compensation from either Borrower unless such Lender is actively seeking compensation from other similarly situated borrowers as well.

SECTION 2.14 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan or Alternative Currency Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan or Alternative Currency Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan or Alternative Currency Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.09(c) and is revoked in accordance therewith), or (d) the assignment of any Eurodollar Loan or Alternative Currency Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrowers pursuant to Section 2.18, then, in any such event, the applicable Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan or the rate applicable to Alternative Currency Loans, as applicable, 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 that such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrowers and shall be conclusive absent manifest error. The applicable Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.15 Taxes.

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

(b) [Intentionally Omitted].

(c) Each Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Lender, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Lender, 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 2.15) and any penalties, interest

and reasonable out-of-pocket expenses arising therefrom or with respect thereto, except as a result of the finding by a court of competent jurisdiction in a final, non-appealable order that said sums were imposed as a result of the willful misconduct or gross negligence of the Administrative Agent or Issuing Lender, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to such Borrower by a Lender or the Issuing Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Lender, shall be conclusive absent manifest error. No Administrative Agent, Lender or Issuing Lender shall be entitled to receive any payment with respect to Indemnified Taxes or Other Taxes that are incurred or accrued more than 180 days prior to the date such Administrative Agent, Lender or Issuing Lender gives notice and demand thereof to such Borrower.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by either 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 Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Law of the jurisdiction in which a Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to such 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 such Borrower as will permit such payments to be made without withholding or at a reduced rate.

(f) If the Administrative 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 either Borrower or with respect to which such Borrower has paid additional amounts pursuant to this Section 2.15, 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 2.15 with respect to the Taxes or Other Taxes giving rise to such refund), net of all reasonable out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that such Borrower, upon the request of the Administrative Agent or such Lender, agree to repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to the Borrowers or any other Person.

(g) Each Lender and Issuing Lender shall use its best efforts (consistent with its internal policies and legal and regulatory restrictions) to select a jurisdiction for its applicable lending office or change the jurisdiction of its applicable lending office, as the case may be, so as to avoid the imposition of any Indemnified Taxes or Other Taxes or to eliminate or reduce the

payment of any additional sums under this Section 2.15; provided that no such selection or change of the jurisdiction for its applicable lending office shall be made if, in the reasonable judgment of such Lender or Issuing Lender, such selection or change would be materially disadvantageous to such Lender and Issuing Lender.

SECTION 2.16 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) Each Borrower shall make each payment required to be made by it hereunder on Loans denominated in Dollars (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.13, 2.14 or 2.15, or otherwise) prior to 1:00 p.m., Eastern time, on the date when due in Dollars, in immediately available funds, without set-off or counterclaim. Each Borrower shall make each payment of principal and interest required to be made by it hereunder on Loans denominated in an Alternative Currency at the place designated by the Administrative Agent in its notice therefor in such Alternative Currency. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at Xxx XXXX Xxxxxx, 00xx Xxxxx, Xxxxxxx, Xxx Xxxx 00000, except payments to be made directly to the Issuing Lender as expressly provided herein and except that payments pursuant to Sections 2.13, 2.14, 2.15 and 10.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension.

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

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and

(ii) the provisions of this paragraph shall not be construed to apply to any payment made by a 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 a Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrowers consent to the foregoing and agree, to the extent it may effectively do so under applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Borrower 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 the Administrative Agent shall have received notice from a Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Lender hereunder that such Borrower will not make such payment, the Administrative 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 Lender, as the case may be, the amount due. In such event, if a Borrower has not in fact made such payment, then each of the Lenders or the Issuing Lender, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.04(d) or (e), 2.05(b) or 2.16(d), 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 2.17 Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.13, or if either Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, 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 reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Sections 2.13 or 2.15, 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. Such Borrower shall pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If any Lender requests compensation under Section 2.13, or if either Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, or if any Lender defaults in its obligation

to fund Loans hereunder, then the Borrowers may, at their sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrowers shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

SECTION 2.18 Increase of Commitments.

(a) If no Default or Event of Default shall have occurred and be continuing, the Borrowers may at any time during the Availability Period request an increase of the aggregate Revolving Loan Commitments by notice to the Administrative Agent in writing of the amount of such proposed increase (such notice, a “Commitment Increase Notice”); provided, however, that the Revolving Loan Commitment of any Lender may not be increased without such Lender’s consent, the minimum amount of any such increase shall be $10,000,000, the aggregate amount of the Lenders’ Revolving Loan Commitments shall not exceed $150,000,000 and (iv) the aggregate principal amount of all Foreign Revolving Loans at any time outstanding, shall not exceed sixty percent (60%) of the total of all the Lenders’ Revolving Loan Commitments as such commitments are increased pursuant to this Section 2.18. The Administrative Agent shall, within five (5) Business Days after receipt of the Commitment Increase Notice, notify each Lender of such request. Each Lender desiring to increase its Revolving Loan Commitment shall so notify the Administrative Agent in writing no later than twenty (20) days after receipt by the Lender of such request. Any Lender that accepts an offer to it by the Borrowers to increase its Revolving Loan Commitment pursuant to this Section 2.18 shall, in each case, execute a Commitment Increase Agreement with the Borrowers and the Administrative Agent, whereupon such Lender shall be bound by and entitled to the benefits of this Agreement with respect to the full amount of its Revolving Loan Commitment as so increased, and the definition of Revolving Loan Commitment in hereof shall be deemed to be amended to reflect such increase. Any Lender that does not notify the Administrative Agent within such period that it will increase its Revolving Loan Commitment shall be deemed to have rejected such offer to increase its Revolving Loan Commitment. No Lender shall have any obligation whatsoever to agree to increase its Revolving Loan Commitment. Any agreement to increase a Lender’s pro rata share of the increased Revolving Loan Commitment shall be irrevocable and shall be effective upon notice thereof by the Administrative Agent at the same time as that of all other increasing Lenders.

(b) If any portion of the increased Revolving Loan Commitments is not subscribed for by such Lenders, the Borrowers may, in their sole discretion, but with the consent of the Administrative Agent as to any Person that is not at such time a Lender (which consent shall not be unreasonably withheld or delayed), offer to any existing Lender or to one or more additional banks or financial institutions approved by the Administrative Agent the opportunity to participate in all or a portion of the increased Revolving Loan Commitments pursuant to paragraph (c) or (d) below, as applicable, by notifying the Administrative Agent. Promptly and in any event within five (5) Business Days after receipt of notice from the Borrowers of their desire to offer such unsubscribed commitments to certain existing Lenders, to the additional banks or financial institutions identified therein or such additional banks or financial institutions identified by the Administrative Agent and approved by the Borrowers, the Administrative Agent shall notify such proposed lenders of the opportunity to participate in all or a portion of such unsubscribed portion of the increased Revolving Loan Commitments.

(c) Any additional bank or financial institution that the Borrowers select to offer participation in the increased Revolving Loan Commitments shall execute and deliver to the Administrative Agent a New Lender Agreement setting forth its Revolving Loan Commitment, and upon the effectiveness of such New Lender Agreement such bank or financial institution (a “New Lender”) shall become a Lender for all purposes and to the same extent as if originally a party hereto and shall be bound by and entitled to the benefits of this Agreement, and the signature pages hereof shall be deemed to be amended to add the name of such New Lender and Schedule 2.01 and the definition of Revolving Loan Commitment in Section 1.01 hereof shall be deemed amended to increase the aggregate Revolving Loan Commitments of the Lenders by the Revolving Loan Commitment of such New Lender, provided that the Revolving Loan Commitment of any New Lender shall be an amount not less than $10,000,000. Each New Lender Agreement and Commitment Increase Agreement shall be irrevocable and shall be effective upon notice thereof by the Administrative Agent at the same time as that of all other New Lenders or increasing Lenders.

(d) Any Lender that accepts an offer to it by the Borrowers to increase its Revolving Loan Commitment pursuant to this Section 2.18 shall, in each case, execute a Commitment Increase Agreement with the Borrowers and the Administrative Agent, whereupon such Lender shall be bound by and entitled to the benefits of this Agreement with respect to the full amount of its Revolving Loan Commitment as so increased, and Schedule 2.01 and the definition of Revolving Loan Commitment in Section 1.01 hereof shall be deemed to be amended to reflect such increase. Any Commitment Increase Agreement shall be irrevocable and shall be effective upon notice thereof by the Administrative Agent at the same time as that of all other New Lenders and increasing Lenders.

(e) The effectiveness of any New Lender Agreement or Commitment Increase Agreement shall be contingent upon receipt by the Administrative Agent of such corporate resolutions of the Borrowers and legal opinions of counsel to the Borrowers as the Administrative Agent shall reasonably request with respect thereto, in each case in form and substance reasonably satisfactory to the Administrative Agent. Once a New Lender Agreement or Commitment Increase Agreement becomes effective, the Administrative Agent shall reflect the increases in the Revolving Loan Commitments effected by such agreements by appropriate entries in the Register.

(f) If any bank or financial institution becomes a New Lender pursuant to Section 2.18(c) or any Lender’s Revolving Loan Commitment is increased pursuant to Section 2.18(d), additional Loans made on or after the effectiveness thereof (the “Re-Allocation Date”) shall be made pro rata based on their respective Revolving Loan Commitments in effect on or after such Re-Allocation Date (except to the extent that any such pro rata borrowings would result in any Lender making an aggregate principal amount of Loans in excess of its Revolving Loan Commitment, in which case such excess amount will be allocated to, and made by, such New Lender and/or Lenders with such increased Revolving Loan Commitments to the extent of, and pro rata based on, their respective Revolving Loan Commitments), and continuations of Loans outstanding on such Re-Allocation Date shall be effected by repayment of such Loans on the last day of the Interest Period applicable thereto or, in the case of ABR Loan, on the date of such increase, and the making of new Loans of the same Type pro rata based on the respective Revolving Loan Commitments in effect on and after such Re-Allocation Date.

(g) If on any Re-Allocation Date there is an unpaid principal amount of Eurodollar Loans, such Eurodollar Loans shall remain outstanding with the respective holders thereof until the expiration of their respective Interest Periods (unless the Borrowers elects to prepay any thereof in accordance with the applicable provisions of this Agreement), and interest on and repayments of such Eurodollar Loans will be paid thereon to the respective Lenders holding such Eurodollar Loans pro rata based on the respective principal amounts thereof outstanding.

(h) Upon the effectiveness of any Commitment Increase Agreement, Section 2.08(b), Schedule 2.01 and other pertinent sections hereof shall be automatically and proportionately modified to reflect the increased Revolving Loan Commitment, the exact figures to be agreed between the Borrowers and the Administrative Agent, and all references to the Revolving Loan Commitments shall be deemed amended mutatis mutandis.

ARTICLE VIII

The Administrative Agent

Each of the Lenders and the Issuing Lender hereby irrevocably appoints the Administrative Agent as its agent under the Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto. Each of the Lenders and the Issuing Lender hereby irrevocably appoints the Administrative Agent to act under any Foreign Security Agreement in its own name, for the benefit and on behalf of the Lenders.

The Lender serving as the Administrative 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 the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrowers or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (b) the Administrative Agent 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 Administrative Agent is 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 10.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrowers or any of their Subsidiaries that is communicated to or obtained by the Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it 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 10.02) or in the absence of its own gross negligence or willful misconduct; PROVIDED, HOWEVER, THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH OF THE AGENTS BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS

SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until written notice thereof is given to the Administrative Agent by the Borrowers or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any 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 the Administrative Agent.

The Administrative 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. The Administrative 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. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), 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.

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

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Lender and the Borrowers. Upon any such resignation, the Required Lenders shall have the right, with the consent of the Borrowers, assuming no Default or Event of Default has occurred and is continuing, such consent not to be unreasonably withheld, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Lender, appoint a successor Administrative Agent with the consent of the Borrowers, assuming no Default or Event of Default has occurred and is continuing, such consent not to be unreasonably withheld, which shall be any Lender or a bank with an office in New York, New York or Houston, Texas, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties

and obligations hereunder. The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 10.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

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

SECTION 9.01 The Guarantee. (a) (i) Each Domestic Guarantor the assets of which are all or substantially all comprised of stock or securities in one or more Foreign Subsidiary hereby jointly, severally, unconditionally and irrevocably with every other such Domestic Guarantor guarantees the full and punctual payment (whether at stated maturity, upon acceleration or otherwise) of the principal of and interest on the Foreign Revolving Loans, and the full and punctual payment of all other Secured Obligations (as defined in the Foreign Security Agreement) payable by the Foreign Borrower and any Foreign Guarantor under the Loan Documents or any Lender Swap Agreement to which the Foreign Borrower or any Foreign Guarantor is a party, as applicable.

(ii) Each Domestic Guarantor the assets of which are not all or substantially all comprised of stock or securities in one or more Foreign Subsidiary hereby jointly, severally, unconditionally and irrevocably with every other such Domestic Guarantor guarantees the full and punctual payment (whether at stated maturity, upon acceleration or otherwise) of the principal of and interest on the Foreign Revolving Loans and the Domestic Revolving Loans, and the full and punctual payment of all other Secured Obligations (as defined in the applicable Security Agreement) payable by either Borrower or any other Guarantor under the Loan Documents or any Lender Swap Agreement to which either Borrower or any Guarantor is a party, as applicable. Upon failure by either Borrower or any other Guarantor to pay punctually any such amount, each such Domestic Guarantor shall forthwith on demand pay the amount not so paid at

the place and in the manner specified in this Agreement or the other Loan Documents or under the applicable Lender Swap Agreement.

(iii) The Guarantee contained in clauses (i) and (ii) of this paragraph is a guaranty of payment and not of collection. The Lenders shall not be required to exhaust any right or remedy or take any action against, as applicable, the Domestic Borrower, the Foreign Borrower, the Foreign Guarantors, the Domestic Guarantors or any other Person or any Collateral. Each Domestic Guarantor agrees that, as between such Domestic Guarantor and the Lenders, the Obligations of, as applicable, the Domestic Borrower, the Foreign Borrower, the Foreign Guarantors or the other Domestic Guarantors may be declared to be due and payable for the purposes of this Guarantee notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards the Domestic Borrower or the Foreign Borrower and that in the event of a declaration or attempted declaration, the Obligations of, as applicable, the Domestic Borrower, the Foreign Borrower, the Foreign Guarantors and the other Domestic Guarantors shall immediately become due and payable by each Domestic Guarantor for the purposes of this Guarantee.

(b) (i) Each Foreign Guarantor hereby jointly, severally, unconditionally and irrevocably guarantees the full and punctual payment (whether at stated maturity, upon acceleration or otherwise) of the principal of and interest on the Foreign Revolving Loans, and the full and punctual payment of all other Secured Obligations (as defined in the Foreign Security Agreement) payable by the Foreign Borrower or any other Foreign Guarantor under the Loan Documents or any Lender Swap Agreement to which the Foreign Borrower or any Foreign Guarantor is a party, as applicable. Upon failure by the Foreign Borrower or any other Foreign Guarantor to pay punctually any such amount, each Foreign Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in this Agreement or the other Loan Documents or under the applicable Lender Swap Agreement. This Guarantee is a guaranty of payment and not of collection. The Lenders shall not be required to exhaust any right or remedy or take any action against the Foreign Borrower, the Foreign Guarantors, or any other Person or any Collateral. The Foreign Guarantors agree that, as between the Foreign Guarantors and the Lenders, the Obligations of the Foreign Borrower and the other Foreign Guarantors may be declared to be due and payable for the purposes of this Guarantee notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards the Foreign Borrower and that in the event of a declaration or attempted declaration, the Obligations of the Foreign Borrower and the other Foreign Guarantors shall immediately become due and payable by each Foreign Guarantor for the purposes of this Guarantee.

(ii) In further limitation of the foregoing, and notwithstanding any other provision of this Agreement to the contrary, the payment undertaking of any Luxembourg Guarantor for the obligations of any Obligor which is not a Subsidiary of such Luxembourg Guarantor shall be limited at any time, to an aggregate amount not exceeding ninety-five per cent. (95%) of the greater of :

(1) the Luxembourg Guarantor’s own funds (“capitaux propres”) and the debt owed by such Luxembourg Guarantor to any of its direct or

indirect shareholders, as determined by Article 34 of the Luxembourg law of 19 December 2002 on the register of commerce and companies, accounting and companies annual accounts, as amended, as at the date of this Agreement;

(2) the Luxembourg Guarantor’s own funds (“capitaux propres”) and the debt owed by such Luxembourg Guarantor to any of its direct or indirect shareholders, as determined by Article 34 of the Luxembourg law of 19 December 2002 on the register of commerce and companies, accounting and companies annual accounts, as amended, as at the date the guarantee is called.

The above limitation shall not apply to any amounts borrowed under any Loan and in each case made available, in any form whatsoever, to such Luxembourg Guarantor or any of its Subsidiaries.

(c) The Domestic Borrower hereby unconditionally and irrevocably guarantees the full and punctual payment (whether at stated maturity, upon acceleration or otherwise) of the principal of and interest on the Foreign Revolving Loans, and the full and punctual payment of all other Secured Obligations (as defined in the Foreign Security Agreement) payable by the Foreign Borrower or any Foreign Guarantor under the Loan Documents or any Lender Swap Agreement to which the Foreign Borrower or any Foreign Guarantor is a party, as applicable. Upon failure by the Foreign Borrower or any Foreign Guarantor to pay punctually any such amount, the Domestic Borrower shall forthwith on demand pay the amount not so paid at the place and in the manner specified in this Agreement or the other Loan Documents or under the applicable Lender Swap Agreement. This Guarantee is a guaranty of payment and not of collection. The Lenders shall not be required to exhaust any right or remedy or take any action against the Foreign Borrower, the Foreign Guarantors, or any other Person or any Collateral. The Domestic Borrower agrees that, as between the Domestic Borrower and the Lenders, the Obligations of the Foreign Borrower and the Foreign Guarantors may be declared to be due and payable for the purposes of this Guarantee notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards the Foreign Borrower and that in the event of a declaration or attempted declaration, the Obligations of the Foreign Borrower and the Foreign Guarantors shall immediately become due and payable by the Domestic Borrower for the purposes of this Guarantee.

(d) For the avoidance of doubt, it is the express intention of the Borrowers, the Guarantors, the Administrative Agent, the Issuing Lender and each Lender that nothing herein or in any other Loan Document shall constitute or be deemed to constitute an investment by a Foreign Subsidiary in “United States property” within the meaning of Section 956(c). Accordingly, each party hereto acknowledges and agrees that only the Domestic Guarantors the assets of which are not all or substantially all comprised of stock or securities in one or more Foreign Subsidiary have guaranteed the Obligations of the Domestic Borrower and the guarantees provided in this Article IX shall be construed and limited to give effect to such intention (provided that the foregoing shall not limit the guarantees of the Domestic Guarantors or the Domestic Borrower of the Foreign Revolving Loans or the other Obligations of the Foreign Borrower or its Foreign Subsidiaries). To the extent that any Domestic Guarantor that

has guaranteed the Obligations of the Domestic Borrower holds stock or securities in one or more Foreign Subsidiaries, such Domestic Guarantor’s guarantee of the Domestic Borrower’s Obligations hereunder shall be (and hereby is) limited at all times to an amount equal to the sum of the fair market value of its domestic assets plus 65% of its stock or securities in such Foreign Subsidiary.

SECTION 9.02 Guarantee Unconditional. The respective obligations of each Guarantor and the Domestic Borrower hereunder shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by:

(a) any extension, renewal, settlement, compromise, waiver or release in respect of any Secured Obligation (as defined in the applicable Security Agreement) of either of the Borrowers or any other Guarantor under the Loan Documents or any Lender Swap Agreement, as applicable, by operation of law or otherwise;

(b) any modification, amendment or waiver of or supplement to the Loan Documents or any Lender Swap Agreement;

(c) any release, impairment, non-perfection or invalidity of any direct or indirect security for any obligation of either of the Borrowers or any other Guarantor under the Loan Documents or any Lender Swap Agreement, as applicable;

(d) any change in the corporate existence, structure or ownership of the Borrowers or any other Guarantor, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting either of the Borrowers, any other Guarantor or their respective assets or any resulting release or discharge of any obligation of either of the Borrowers or any other Guarantor contained in the Loan Documents or any Lender Swap Agreement, as applicable;

(e) the existence of any claim, set-off or other rights which the Guarantor may have at any time against either of the Borrowers, any other Guarantor, the Administrative Agent, any Lender or any other Person, whether in connection herewith or any unrelated transactions, provided that nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim;

(f) any invalidity or unenforceability relating to or against either of the Borrowers or any other Guarantor for any reason of the Loan Documents or any Lender Swap Agreement, as applicable, or any provision of applicable law or regulation purporting to prohibit the payment by either of the Borrowers or any other Guarantor of the principal of or interest on any Loan or any other amount payable by either of the Borrowers or any other Guarantor under the Loan Documents or any Lender Swap Agreement, as applicable; or

(g) any other act or omission to act or delay of any kind by either of the Borrowers, any other Guarantor, the Administrative Agent, any Lender or any other Person or any other circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the Guarantor’s obligations hereunder.

Furthermore, notwithstanding that the Borrowers may not be obligated to the Administrative Agent and/or the Lenders for interest and/or attorneys’ fees and expenses on, or in connection with, any Obligations from and after the Petition Date as a result of the provisions of the federal bankruptcy law or otherwise, Obligations for which the Guarantors shall be obligated shall include interest accruing on the Obligations at the Default Rate from and after the date on which such Borrower files for protection under the federal bankruptcy laws or from and after the date on which an involuntary proceeding is filed against such Borrower under the federal bankruptcy laws (herein collectively referred to as the “Petition Date”) and all reasonable attorneys’ fees and expenses incurred by the Administrative Agent and the Lenders from and after the Petition Date in connection with the Obligations.

SECTION 9.03 Discharge Only upon Payment in Full; Reinstatement In Certain Circumstances. The obligations of each Guarantor and the Domestic Borrower hereunder shall remain in full force and effect until the Revolving Loan Commitments shall have terminated and the principal of and interest on the Loans and all other amounts payable by the Obligors under the Loan Documents or any Lender Swap Agreement, as applicable, shall have been paid in full. If at any time any payment of the principal of or interest on any Loan or any other amount payable by the Obligors under the Loan Documents or any Lender Swap Agreement, as applicable, is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of any Obligor or otherwise, the obligations of each of the Guarantors and the Domestic Borrower hereunder with respect to such payment shall be reinstated at such time as though such payment had been due but not made at such time. The Domestic Guarantors under Section 9.01(a)(i) jointly and severally agree to indemnify each Foreign Revolving Lender, the Domestic Guarantors under Section 9.01(a)(ii) jointly and severally agree to indemnify each Domestic Revolving Lender and the Foreign Guarantors jointly and severally agree to indemnify each Foreign Revolving Lender on demand for all reasonable costs and expenses (including reasonable fees of counsel) incurred by such Lender in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law, other than any costs or expenses resulting from the bad faith or willful misconduct of such Lender.

SECTION 9.04 Waiver by Each Guarantor. Each Guarantor irrevocably waives acceptance hereof, diligence, presentment, demand, protest notice of acceleration or the intent to accelerate and any other notice not provided for in this Article IX, as well as any requirement that at any time any action be taken by any Person against the Borrowers or any other Guarantor or any other Person.

SECTION 9.05 Subrogation. Each Domestic Guarantor under Section 9.01(a)(ii) shall be subrogated to all rights of the Domestic Revolving Lenders, the Administrative Agent and the holders of the Domestic Revolving Loans against the Domestic Borrower in respect of any amounts paid by such Domestic Guarantor pursuant to the provisions of this Article IX, and each of the Domestic Guarantors under Section 9.01(a)(i), the Foreign Guarantors and the Domestic Borrower shall be subrogated to all rights of the Foreign Revolving Lender the Administrative Agent and the holders of the Foreign Revolving Loans against the Foreign Borrower; provided that such Guarantor or the Domestic Borrower shall not be entitled to enforce or to receive any payments arising out of or based upon such right of subrogation until

the principal of and interest on the Loans and all other sums at any time payable by the Borrowers under the Loan Documents or any Lender Swap Agreement, as applicable, shall have been paid in full. If any amount is paid to any Guarantor or the Domestic Borrower, as applicable on account of subrogation rights under these Guarantees at any time when all the Obligations have not been paid in full, the amount shall be held in trust for the benefit of the Domestic Revolving Lenders and the Foreign Revolving Lenders, as applicable, and shall be promptly paid to the Administrative Agent to be credited and applied to the Obligations, whether matured or unmatured or absolute or contingent, in accordance with the terms of this Agreement.

SECTION 9.06 Stay of Acceleration. If acceleration of the time for payment of any amount payable by any Obligor under the Loan Documents or any Lender Swap Agreement, as applicable, is stayed upon insolvency, bankruptcy or reorganization of the Domestic Borrower, all such amounts otherwise subject to acceleration under the terms of this Agreement shall nonetheless be payable by each Domestic Guarantor under Section 9.01(a)(ii) for its respective Obligations described hereunder promptly following demand by the Administrative Agent made at the request of the requisite proportion of the Lenders specified in Article X of this Agreement.

If acceleration of the time for payment of any amount payable by any Obligor under the Loan Documents or any Lender Swap Agreement, as applicable, is stayed upon insolvency, bankruptcy or reorganization of the Foreign Borrower, all such amounts otherwise subject to acceleration under the terms of this Agreement shall nonetheless be payable by each Domestic Guarantor under Section 9.01(a)(i), each Foreign Guarantor and the Domestic Borrower hereunder for its respective Obligations as described in this Article IX promptly following demand by the Administrative Agent made at the request of the requisite proportion of the Lenders specified in Article X of this Agreement.

SECTION 9.07 Instrument for the Payment of Money. Each Guarantor acknowledges that the Guarantees in this Article IX constitutes an instrument for the payment of money and consents and agrees that any Lender or the Administrative Agent, at its sole option, in the event of a dispute by such Guarantor in the payment of any moneys due hereunder, shall have the right to bring a motion-action under New York CPLR Section 3213.

SECTION 9.08 Limit of Liability. The obligations of each of the Guarantors and the Domestic Borrower hereunder shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any applicable state law.

SECTION 9.09 Release upon Sale. Upon any sale of any Guarantor permitted by this Agreement, and, if required hereunder, payment to the Administrative Agent, for the prorata benefit of the applicable Lenders, of the proceeds of such sale, such Guarantor shall (a) be released from its obligations as a Guarantor hereunder, (b) all Liens, if any, securing such Guarantee shall automatically be terminated and released and (c) the Administrative Agent will, at the expense of said Guarantor, execute and deliver such documents as are reasonably necessary to evidence said releases and terminations, following written request from the applicable Borrower and receipt by the Administrative Agent of a certificate from the applicable Borrower certifying no Default or Event of Default exists.

SECTION 9.10 Benefit to Guarantor. Each Guarantor acknowledges that the Loans made to the Borrowers will be, in part, re-loaned to, or used for the benefit of, such Guarantor and its Affiliates, that each Guarantor, because of the utilization of the proceeds of the Loans, will receive a direct benefit from the Loans and that, without the Loans, such Guarantor would not be able to continue its operations and carry on its business as presently conducted. The guarantee of any Dutch Guarantor shall be deemed to have been given only to the extent that such guarantee does not violate the prohibition on financial assistance contained in Sections 2:98c and 2:207c of the Dutch Civil Code (Burgerlijk Wetboek).

SECTION 10.02 Waivers; Amendments. (a) No failure or delay by the Administrative Agent, the Issuing Lender or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Lender and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrowers or Guarantors therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a

waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Lender may have had notice or knowledge of such Default at the time.

(b) Except as otherwise provided herein, neither this Agreement nor the other Loan Documents nor any provision hereof or thereof may be waived, amended or modified except pursuant to (x) an agreement or agreements in writing entered into by the Borrowers and the Required Lenders or by the Borrowers and the Administrative Agent with the consent of the Required Lenders or (y) an agreement or agreements in writing entered into by the Borrowers and the Super Majority Lenders for the purpose of reducing the interest rate applicable to overdue amounts; provided that no such agreement shall (i) increase the Revolving Loan 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 directly 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 Revolving Loan Commitment, without the written consent of each Lender directly affected thereby, (iv) change Section 2.10 or Sections 2.16(b) or(c), in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section 10.02(b) or the definition of “Required Lenders” 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, (vi) release all or substantially all of the Collateral without the written consent of each Lender, provided, that nothing herein shall prohibit the Administrative Agent from releasing any Collateral, or require the consent of the other Lenders for such release, in respect of items sold to the extent such sale is permitted or not prohibited hereunder, or (vii) release all or substantially all of the Guarantees (other than in connection with any transactions permitted by the Credit Agreement) without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Issuing Lender hereunder without the prior written consent of the Administrative Agent or the Issuing Lender, as the case may be.

(a) The Borrowers shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the fees, charges and disbursements of one primary law firm as counsel and consultants for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, due diligence undertaken by the Administrative Agent with respect to the financing contemplated by this Agreement, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Lender in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all reasonable out-of-pocket expenses incurred by the Administrative Agent, the Issuing Lender or any Lender for fees, charges and disbursements of one primary law firm as counsel, local counsel as needed and consultants for the Administrative Agent, the Issuing Lender or any Lender and all other reasonable out-of-pocket expenses of the

Administrative Agent, the Issuing Lender or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement during the existence of a Default or an Event of Default (whether or not any waiver or forbearance has been granted in respect thereof), including its rights under this Section, or in connection with the Loans made or Letters of Credit issued hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

(b) Each Borrower shall indemnify the Administrative Agent, the Issuing Lender 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 Lender 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 Borrowers or any of their Subsidiaries, or any Environmental Liability related in any way to the Borrowers or any of their Subsidiaries, or (iv) any actual 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; and whether or not caused by the ordinary, sole or contributory negligence of any Indemnitee, provided further 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 (IT BEING UNDERSTOOD THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH OF THE INDEMNITEES BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL). It is agreed by the parties hereto that the indemnity obligations of the Domestic Borrower under the Commitment Letter are superseded to the extent described in this Agreement.

To the extent that a Borrower fails to pay any amount required to be paid by it to the Administrative Agent or the Issuing Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent or the Issuing Lender, as the case may be, such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or the Issuing Lender in its capacity as such. For purposes hereof, a Lender’s “pro rata share” shall be determined based upon its share of the sum of the total Revolving Credit Exposure and unused Revolving Loan Commitments at the time.

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

All amounts due under this Section shall be payable promptly after receipt of a request therefore by any Borrower.

SECTION 10.04 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 Lender that issues any Letter of Credit), except that (i) the Borrowers may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrowers 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 Lender 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 Administrative Agent, the Issuing Lender and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

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

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

(B) the Administrative Agent and the Issuing Lender, provided that no such consent shall be required for an assignment of any Revolving Loan Commitment to an assignee that is a Lender or an Affiliate of a Lender with a Revolving Loan 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 Revolving Loan Commitment or Loans, the amount of the Revolving Loan Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the

Administrative Agent) shall not be less than $5,000,000 and after giving effect to such assignment, the assigning Lender Revolving Loan Commitment or Loans shall not be less than $5,000,000 (which amount shall be in the aggregate in the event of simultaneous assignments to or by two or more Approved Funds) unless each of the Borrowers and the Administrative Agent otherwise consent, provided that no such consent of the Borrowers shall be required if an Event of Default under clause (a), (b), (h) or (i) of Section 7.01 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 $3,500 (provided that only one such fee shall be payable in the event of simultaneous assignments to or by two or more Approved Funds);

(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 include material non-public information about the Borrowers or Guarantors and their Related Parties or their respective securities) will be made available and who may receive such information in accordance with such assignee’s compliance procedures and applicable law, including Federal and state securities laws; and

(E) prior to any assignment to an assignee that is not a Lender, the Lender making such an assignment shall first offer the assignment to the other Lenders who shall have five (5) Business Days to purchase the assignment on the same terms as are proposed to such non-Lender assignee.

Section 10.04(b)(ii)(B) shall not be construed to prohibit assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of Revolving Loan Commitments or Loans.

For the purpose of this Section 10.04(b), the term “Approved Fund” has the following meaning:

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

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent

of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.14, 2.15 and 10.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

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

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. 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 Agent or the Issuing Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Revolving Loan Commitment and the Loans owing to it); provided that (A) such participations must be approved by the Borrowers so long as no Default has occurred and is continuing, such approval not to be unreasonably withheld, (B) such Lender’s obligations under this Agreement shall remain unchanged, (C) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (D) the Borrowers, the Administrative Agent, the Issuing Lender 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 10.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrowers agrees that each Participant shall be entitled to the benefits of Sections 2.13, 2.14 and 2.15 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 10.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.16(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.13 or 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers’ prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.16 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.16(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.

SECTION 10.05 Survival. All covenants, agreements, representations and warranties made by the Borrowers and each Guarantor 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, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Lender or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Revolving Loan Commitments have not expired or terminated. The provisions of Sections 2.13, 2.14, 2.15 and 10.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Revolving Loan Commitments or the termination of this Agreement or any provision hereof.

SECTION 10.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts and may be delivered in original or facsimile form (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 the other Loan Documents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to

the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 10.07 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 10.08 Right of Setoff. Each Lender and each of its Affiliates is hereby authorized at any time that an Event of Default shall have occurred and is continuing and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrowers or any Guarantor against any and all of the obligations of the Borrowers and each Guarantor now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 10.13 Interest Rate Limitation. It is the intention of the parties hereto to conform strictly to applicable interest, usury and criminal laws and, anything herein to the contrary notwithstanding, the obligations of Borrowers and the Guarantors to a Lender, the Issuing Lender or the Administrative Agent under this Agreement or any Loan Document shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender, such Issuing Lender or Administrative Agent limiting rates of interest which may be charged or collected by such Lender, such Issuing Lender or Administrative Agent. Accordingly, if the transactions contemplated hereby or thereby would be illegal, unenforceable, usurious or criminal under laws applicable to a Lender, the Issuing Lender or the Administrative Agent (including the laws of any jurisdiction whose laws may be mandatorily applicable to such Lender or Administrative Agent notwithstanding anything to the contrary in this Agreement or any other Loan Document then, in that event, notwithstanding anything to the contrary in this Agreement or any other Loan Document, it is agreed as follows:

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

(b) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received under this Agreement or any Loan Document or otherwise in connection with this Agreement or any Loan Document by such Lender, such Issuing Lender or such Administrative Agent shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to each Lender, each Issuing Lender and the Agents herein called the “Highest Lawful Rate”), and any excess shall be cancelled automatically and if theretofore paid shall be credited to Borrowers by such Lender, such Issuing Lender or such Administrative Agent (or, if such consideration shall have been paid in full, such excess refunded to Borrowers);

(c) all sums paid, or agreed to be paid, to such Lender, such Issuing Lender or such Administrative Agent for the use, forbearance and detention of the indebtedness of Borrowers to such Lender, such Issuing Lender or such Administrative Agent hereunder or under any Loan Document shall, to the extent permitted by laws applicable to such Lender, such Issuing Lender or such Administrative Agent, as the case may be, be amortized, prorated,

allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof;

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

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

SECTION 10.14 USA Patriot Act. Each Lender hereby notifies the Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of the Borrowers and other information that will allow such Lender to identify the Borrowers in accordance with the Act.

SECTION 10.15 Final Agreement of the Parties. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES WITH RESPECT TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

SECTION 10.16 Amendment and Restatement; Purchase and Sale of Loans and Participations. This Agreement is an amendment and restatement of the Original Agreement in its entirety upon and subject to the terms, conditions and provisions herein.

The Existing Lenders hereby sell, assign, transfer and convey, and Lenders hereby purchase and accept, so much of the loans and obligations outstanding pursuant to the Original Agreement and all of the related rights, titles, benefits, interests, privileges, claims, liens, security interests, and obligations existing and to exist (collectively the “Interests”) such that, after giving effect to such conveyances, each Lender’s commitment and share of outstanding loans and obligations under the Original Agreement, as continued pursuant to this Agreement, shall be equal to the Revolving Loan Commitment and Revolving Credit Exposure, respectively, of such Lender, provided that the Lenders shall not be liable for any act or omission of the Existing Lenders occurring prior to the Effective Date. The foregoing assignments, transfers and conveyances are without recourse to the Existing Lenders and without any warranties whatsoever by the administrative agent under the Original Agreement or any Existing Lender as to title, enforceability, collectibility, documentation or freedom from liens or encumbrances, in whole or in part, other than the warranty by each Existing Lender that it has not previously sold, transferred, conveyed or encumbered such Interests. Each Lender so acquiring a part of such outstanding loans assumes its Revolving Loan Commitment of the outstanding loans, commitments, rights, titles, interests, privileges, claims, liens, security interests, benefits and obligations under this Agreement and the other Loan Documents.
