(a) Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to the Borrower in a single Borrowing (on a day which shall be a Business Day) occurring on or prior to the Commitment Termination Date in an aggregate principal amount that will not result in (i) such Lender’s Exposure exceeding such Lender’s Commitment or (ii) the sum of the Exposures of all of the Lenders exceeding the Aggregate Commitments.

(b) Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow the Loans. No amounts paid or prepaid with respect to the Loans may be reborrowed.

SECTION 2.02. Loans; Requests for Borrowings. (a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Each Lender at its option may make any Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) At the commencement of each Interest Period for any Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $5,000,000 and not less than $10,000,000 and there shall not at any time be more than one Loan outstanding under this Agreement.

Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent and signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information:

(i) the aggregate amount of the requested Borrowing, and

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

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 2.03. [Intentionally Omitted].

SECTION 2.04. [Intentionally Omitted].

SECTION 2.05. Funding of Borrowings. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 3:00 p.m., New York City 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 by promptly crediting the amounts so received, in like funds, to an account established and maintained by the Borrower at the Administrative Agent’s office in New York City.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time 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 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, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the Federal Funds Effective Rate or (ii) in the case of the Borrower, the interest rate applicable to such Borrowing. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Borrower shall prepay Loans in such aggregate amount (together with accrued interest thereon to the extent required by Section 2.13) as shall be necessary so that, after giving effect to such prepayment, the Total Outstanding Principal does not exceed the Aggregate Commitments.

(b) Each prepayment of Loans pursuant to this Section 2.08 shall be accompanied by the Borrower’s payment of any amounts payable under Section 2.16 in connection with such prepayment. Prepayments of Loans shall be applied ratably to the Loans so prepaid.

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

(e) Any Lender may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 11.04) 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 2.12. Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee (each a “Facility Fee”), which shall accrue at the rate of 0.375% per annum on the daily amount of the Commitment of such Lender (whether used or unused) during the period from and including the Effective Date to but excluding the date set forth in clause (a) of the definition of “Termination Date.” Accrued Facility Fees shall be payable in arrears on the last day of December and on the Termination Date, commencing on the first such date to occur after the Effective Date. All Facility Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) The Borrower agrees to pay to the Administrative Agent for the account of the Lenders an upfront fee (the “Upfront Fee”) in the aggregate amount of $150,000, payable in full on the Effective Date.

SECTION 2.13. Interest. (a) The Loans shall bear interest at a rate per annum equal to the LIBO Rate for a three-month Interest Period.

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

(c) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan; provided that (i) interest accrued pursuant to paragraph (b) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan, accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) all accrued interest shall be payable upon termination of the Commitments.

(d) All interest hereunder shall be computed on the basis of a year of 360 days, and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

SECTION 2.14. [Intentionally Omitted].

SECTION 2.15. Increased Costs. (a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by,

any Lender (except any such reserve requirement described in paragraph (e) of this Section), or

(ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Loans made by such Lender 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 Loan and participation interests therein (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender, as the case may be, such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b) If any 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 capital or on the capital of its holding company, if any, as a consequence of this Agreement to a level below that which such Lender or its holding company could have achieved but for such Change in Law (taking into consideration its policies and the policies of its holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender, as the case may be, such additional amount or amounts as will compensate it or its holding company for any such reduction suffered.

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

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of its right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs or reductions incurred more than ninety days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of its 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 ninety day period referred to above shall be extended to include the period of retroactive effect thereof.

(e) The Borrower shall pay (without duplication as to amounts paid under this Section 2.15) to each Lender, so long as such Lender shall be required under regulations of the Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Loan of such Lender, from the date of such Loan until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the LIBO Rate for the Interest Period for such Loan from (ii) the rate obtained by dividing such LIBO Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Loan. Such additional interest determined

by such Lender and notified to the Borrower and the Administrative Agent, accompanied by the calculation of the amount thereof, shall be conclusive and binding for all purposes absent manifest error.

SECTION 2.16. Break Funding Payments. In the event of (a) the payment of any principal of any Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default); (b) the failure to borrow or prepay any Loan on the date specified in any notice delivered pursuant hereto, or (c) the assignment of any Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.19, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Loan, the loss to any Lender attributable to any such event shall be deemed to include an amount reasonably determined by such Lender to be equal to the excess, if any, of (x) the amount of interest that such Lender would pay for a deposit equal to the principal amount of such Loan for the period from the date of such payment, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, the duration of the Interest Period that would have resulted from such borrowing) if the interest rate payable on such deposit were equal to the LIBO Rate for such Interest Period, over (y) the amount of interest that such Lender would earn on such principal amount for such period if such Lender were to invest such principal amount for such period at the interest rate that would be bid by such Lender (or an affiliate of such Lender) for dollar deposit from other banks in the eurodollar market at the commencement of such period. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.17. Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if any Credit Party 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 or 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 Credit Party shall make such deductions and (iii) such Credit Party shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (and for any Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, or such Lender, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority.

A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

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

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the laws of the jurisdiction in which the Borrower or the Guarantor is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with an additional original or a photocopy, as required under applicable rules and procedures, to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as shall be necessary to permit such payments to be made without withholding or at a reduced rate. Further, in those circumstances as shall be necessary to allow payments hereunder to be made free of (or at a reduced rate of) withholding tax, each other Lender and the Administrative Agent, as applicable, shall deliver to Borrower such documentation as the Borrower may reasonably request in writing.

(f) Except with the prior written consent of the Administrative Agent, all amounts payable by a Credit Party hereunder shall be made by such Credit Party in its own name and for its own account from within the United States by a payor that is a United States person (within the meaning of Section 7701 of the Code).

SECTION 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-Offs. (a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or under Section 2.15, 2.16, 2.17 or 11.03, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 1301 Avenue of the Americas, New York, New York, except that payments pursuant to Sections 2.15, 2.16, 2.17 and 11.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due

hereunder, such funds shall be applied (i) first, to pay 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, to pay principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal 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 the Obligations owing to it resulting in such Lender receiving payment of a greater proportion of the aggregate amount of such Obligations 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 of, or other Obligations owing to, 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 or other Obligations, as applicable; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Guarantor, the Borrower or any other Subsidiary or Affiliate of the Guarantor (as to which the provisions of this paragraph shall apply). The Borrower and the Guarantor consent to the foregoing and agree, to the extent they may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower and the Guarantor rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower or the Guarantor in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such 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 Federal Funds Effective Rate.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Sections 2.05(b) or 2.18(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 2.19. Mitigation Obligations; Replacement of Lenders. (a) Any Lender claiming reimbursement or compensation from the Borrower under either of Sections 2.15 and 2.17 for any losses, costs or other liabilities shall use reasonable efforts (including, reasonable efforts to designate a different lending office of such Lender for funding or booking its Loans or to assign its rights and obligations hereunder to another of its offices, branches or affiliates) to mitigate the amount of such losses, costs and other liabilities, if such efforts can be made and such mitigation can be accomplished without such Lender suffering (i) any economic disadvantage for which such Lender does not receive full indemnity from the Borrower under this Agreement or (ii) otherwise be disadvantageous to such Lender.

(b) In determining the amount of any claim for reimbursement or compensation under Sections 2.15 and 2.17, each Lender will use reasonable methods of calculation consistent with such methods customarily employed by such Lender in similar situations.

(c) Each Lender will notify the Borrower either directly or through the Administrative Agent of any event giving rise to a claim under Section 2.15 or Section 2.17 promptly after the occurrence thereof which notice shall be accompanied by a certificate of such Lender setting forth in reasonable detail the circumstances of such claim.

(d) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 11.04), 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 Borrower 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, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

ARTICLE IX

THE ADMINISTRATIVE AGENT

SECTION 9.01. The Administrative Agent. (a) Each of the Lenders hereby irrevocably appoints the Administrative Agent as its agent 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.

(b) The Person 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 any Credit Party or any of such Credit Party’s Subsidiaries or other Affiliates thereof as if it were not the Administrative Agent hereunder.

(c) The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (i) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (ii) 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 by the Required Lenders, and (iii) 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 Borrower, the Guarantor or any of its other Subsidiaries that is communicated to or obtained by the bank serving as 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, if applicable, all of the Lenders) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (1) any statement, warranty or representation made in or in connection with this Agreement, (2) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (3) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (4) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (5) the satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent and the conformity thereof to such express requirement.

(d) 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 a Credit Party) 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.

(e) The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent,

and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

(f) 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 and the Credit Parties. Upon any such resignation, the Required Lenders shall have the right, with the consent of the Borrower (which consent shall not unreasonably be 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, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank, in any event having total assets in excess of $500,000,000 and who shall serve until such time, if any, as an Agent shall have been appointed as provided above. 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 Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 11.03 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent.

(g) 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.

(h) No Lender identified on the signature pages of this Agreement as a “Lead Arranger” or “Book Runner”, or that is given any other title hereunder other than “Administrative Agent”, shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the generality of the foregoing, no Lender so identified as a “Lead Arranger” or that is given any other title hereunder, shall have, or be deemed to have, any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on the Lenders so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

ARTICLE X

GUARANTY

SECTION 10.01. The Guaranty. (a) The Guarantor, as primary obligor and not merely as a surety, hereby irrevocably, absolutely and unconditionally guarantees to the Administrative Agent and the Lenders and each of their respective successors, endorsees, transferees and assigns (each a “Beneficiary” and collectively, the “Beneficiaries”) the prompt and complete payment by the Borrower, as and when due and payable, of the Obligations, in accordance with the terms of the Credit Documents. The provisions of this Article X are sometimes referred to hereinafter as the “Guaranty”.

(b) The Guarantor hereby guarantees that the Obligations will be paid strictly in accordance with the terms of the Credit Documents, regardless of any law now or hereafter in effect in any jurisdiction affecting any such terms or the rights of the Beneficiaries with respect thereto. The obligations and liabilities of the Guarantor under this Guaranty shall be absolute and unconditional irrespective of: (i) any lack of validity or enforceability of any of the Obligations or any Credit Document, or any delay, failure or omission to enforce or agreement not to enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise of any right with respect to the foregoing (including, in each case, without limitation, as a result of the insolvency, bankruptcy or reorganization of any Beneficiary, the Borrower or any other Person), (ii) any change in the time, manner or place of payment of, or in any other term in respect of, all or any of the Obligations, or any other amendment or waiver of or consent to any departure from the Credit Documents or any agreement or instrument relating thereto, (iii) any exchange or release of, or non-perfection of any Lien on or in any collateral, or any release, amendment or waiver of, or consent to any departure from, any other guaranty of, or agreement granting security for, all or any of the Obligations, (iv) any claim, set-off, counterclaim, defense or other rights that the Guarantor may have at any time and from time to time against any Beneficiary or any other Person, whether in connection with this Transaction or any unrelated transaction, or (v) any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower or any other guarantor or surety in respect of the Obligations or the Guarantor in respect hereof.

(c) The Guaranty provided for herein (i) is a guaranty of payment and not of collection, (ii) is a continuing guaranty and shall remain in full force and effect until the Commitments have been terminated and the Obligations have been paid in full in cash, and (iii) shall continue to be effective or shall be reinstated, as the case may be, if at any time any payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be returned by any Beneficiary upon or as a result of the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or otherwise, all as though such payment had not been made.

(d) The obligations and liabilities of the Guarantor hereunder shall not be conditioned or contingent upon the pursuit by any Beneficiary or any other Person at any time of any right or remedy against the Borrower or any other Person that may be or

become liable in respect of all or any part of the Obligations or against any collateral security or guaranty therefor or right of setoff with respect thereto.

(e) The Guarantor hereby consents that, without the necessity of any reservation of rights against the Guarantor and without notice to or further assent by the Guarantor, any demand for payment of any of the Obligations made by any Beneficiary may be rescinded by such Beneficiary and any of the Obligations continued after such rescission.

(f) The Guarantor’s obligations under this Guaranty shall be unconditional, irrespective of any lack of capacity of the Borrower or any lack of validity or enforceability of any other provision of this Agreement or any other Credit Document, and this Guaranty shall not be affected in any way by any variation, extension, waiver, compromise or release of any or all of the Obligations or of any security or guaranty from time to time therefor.

(g) The obligations of the Guarantor under this Guaranty shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any proceeding or action, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, marshalling of assets, assignment for the benefit of creditors, composition with creditors, readjustment, liquidation or arrangement of the Borrower or any similar proceedings or actions, or by any defense the Borrower may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding or action. Without limiting the generality of the foregoing, the Guarantor’s liability shall extend to all amounts and obligations that constitute the Obligations and would be owed by the Borrower, but for the fact that they are unenforceable or not allowable due to the existence of any such proceeding or action.

SECTION 10.02. Waivers. (a) The Guarantor hereby unconditionally waives: (i) promptness and diligence, (ii) notice of or proof of reliance by the Administrative Agent or the Lenders upon this Guaranty or acceptance of this Guaranty, (iii) notice of the incurrence of any Obligation by the Borrower or the renewal, extension or accrual of any Obligation or of any circumstances affecting the Borrower’s financial condition or ability to perform the Obligations, (iv) notice of any actions taken by the Beneficiaries or the Borrower or any other Person under any Credit Document or any other agreement or instrument relating thereto, (v) all other notices, demands and protests, and all other formalities of every kind in connection with the enforcement of the Obligations, of the obligations of the Guarantor hereunder or under any other Credit Document, the omission of or delay in which, but for the provisions of this Article X might constitute grounds for relieving the Guarantor of its obligations hereunder, (vi) any requirement that the Beneficiaries protect, secure, perfect or insure any Lien or any property subject thereto, or exhaust any right or take any action against the Borrower or any other Person or any collateral, and (vii) each other circumstance, other than payment of the Obligations in full, that might otherwise result in a discharge or exoneration of, or constitute a defense to, the Guarantor’s obligations hereunder.

(b) No failure on the part of any Beneficiary to exercise, and no delay in exercising, any right, remedy, power or privilege hereunder or under any Credit Document or any other agreement or instrument relating thereto shall operate as a waiver

thereof, nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or under any Credit Document or any other agreement or instrument relating thereto preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. This Guaranty is in addition to and not in limitation of any other rights, remedies, powers and privileges the Beneficiaries may have by virtue of any other instrument or agreement heretofore, contemporaneously herewith or hereafter executed by the Guarantor or any other Person or by applicable law or otherwise. All rights, remedies, powers and privileges of the Beneficiaries shall be cumulative and may be exercised singly or concurrently. The rights, remedies, powers and privileges of the Beneficiaries under this Guaranty against the Guarantor are not conditional or contingent on any attempt by the Beneficiaries to exercise any of their rights, remedies, powers or privileges against any other guarantor or surety or under the Credit Documents or any other agreement or instrument relating thereto against the Borrower or against any other Person.

(c) The Guarantor hereby acknowledges and agrees that, until the Commitments have been terminated and all of the Obligations have been paid in full in cash, under no circumstances shall it be entitled to be subrogated to any rights of any Beneficiary in respect of the Obligations performed by it hereunder or otherwise, and the Guarantor hereby expressly and irrevocably waives, until the Commitments have been terminated and all of the Obligations have been paid in full in cash, (i) each and every such right of subrogation and any claims, reimbursements, right or right of action relating thereto (howsoever arising), and (ii) each and every right to contribution, indemnification, set-off or reimbursement, whether from the Borrower or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, and whether arising by contract or operation of law or otherwise by reason of the Guarantor’s execution, delivery or performance of this Guaranty.

(d) The Guarantor represents and warrants that it has established adequate means of keeping itself informed of the Borrower’s financial condition and of other circumstances affecting the Borrower’s ability to perform the Obligations, and agrees that neither the Administrative Agent nor any Lender shall have any obligation to provide to the Guarantor any information it may have, or hereafter receive, in respect of the Borrower.

SECTION 11.02. Waivers; Amendments. (a) No failure or delay by the Administrative Agent, 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 and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any Credit Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

(b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower, the Guarantor and the Required Lenders or by the Borrower, the Guarantor and the Administrative Agent with the consent of the Required Lenders; provided that if the representations or covenants under the Existing Agreement are amended, waived or otherwise modified pursuant to an agreement or agreements in writing permitted under

the Existing Agreement, then the analogous representations and covenants under this Agreement shall automatically be amended, waived or modified to the same extent, and, provided further, that no such agreement referred to in this Section 11.02(b) shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees or other amounts payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees or other amounts payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) release the Guarantor from its obligations under the Guaranty without the written consent of each Lender, (vi) waive any of the conditions precedent to the effectiveness of this Agreement set forth in Section 3.01 without the written consent of each Lender, or (vii) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided, further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent.

SECTION 11.03. Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including (in an amount not to exceed $15,000), the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the initial syndication of the credit facilities provided for herein, the preparation and administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), and (ii) all reasonable out of-pocket expenses incurred by the Administrative Agent or any Lender, including the reasonable fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, or in connection with the Loans made, including in connection with any workout, restructuring or negotiations in respect thereof.

(b) The Borrower shall indemnify the Administrative Agent 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 reasonable expenses, including the reasonable 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 transaction contemplated hereby, (ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property now, in the past or hereafter

owned or operated by the Borrower, the Guarantor or any of its other Subsidiaries, or any Environmental Liability related in any way to the Borrower, the Guarantor or any of its other Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

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

(d) To the extent permitted by applicable law, each party hereto shall not assert, and hereby waives, any claim against each other party, 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 or any Loan or the use of the proceeds thereof.

(e) All amounts due under this Section shall be payable not later than 20 days after written demand therefor.

SECTION 11.04. 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; provided that, except to the extent permitted pursuant to Section 6.01(b)(ii), (iii) or (iv), no Credit Party may 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 a Credit Party without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans and other Obligations at the time owing to it); provided that (i) except in the case of an assignment to a Lender or an Affiliate of a Lender, each of the Administrative Agent, and, so long as no Event of Default is continuing, the Borrower must give its prior written consent to such assignment (which consent, in the case of the Administrative Agent and the Borrower, shall not unreasonably be withheld), (ii) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire

remaining amount of the assigning Lender’s Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Administrative Agent and, so long as no Event of Default shall be continuing, the Borrower otherwise consent, (iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, (iv) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500, and (v) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. Upon acceptance and recording pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 11.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section.

(c) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in The City of New York a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans and other Obligations 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 Borrower, the Administrative Agent 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.

(d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Acceptance 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.

(e) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a

portion of its Commitment and the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Guarantor and the Administrative Agent 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 11.02(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16 and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.15 or 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as though it were a Lender.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement 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 assignee for such Lender as a party hereto.

(h) Anything herein to the contrary notwithstanding, each Lender (the “Granting Lender”) shall have the right, without the prior consent of the Borrower, to grant to a special purpose funding vehicle (the “SPFV”) that is utilized by such Granting Lender, identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide all or any part of any Loan that such Granting Lender would otherwise be obligated to make hereunder, provided that (i) nothing herein shall constitute a commitment to make any Loan by any SPFV or shall relieve its Granting Lender of any obligation of such Granting Lender hereunder or under any other Credit Document, except to the extent that such SPFV actually funds all or part of any Loan such Granting Lender is obligated to make hereunder, (ii) if an SPFV elects not to exercise such option or otherwise fails to provide all or any part of such Loan, such Granting Lender shall be obligated to make such Loan pursuant to the terms hereof, (iii) the Granting Lender hereby indemnifies and holds the Administrative Agent harmless from and against any liability, loss, cost or expense (including for or in respect of Taxes) arising out of such identification and grant or any transaction contemplated thereby, and (iv) the provisions of this paragraph (h) shall not impose any increased cost

or liability on any Credit Party. The making of a Loan by an SPFV hereunder shall utilize the Commitment of its Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto agrees that no SPFV shall be liable for any payment under this Agreement or any other Credit Document for which a Lender would otherwise be liable, for so long as, and to the extent that, its Granting Lender makes such payment. As to any Loans or portions of Loans made by it, each SPFV shall have all the rights that a Lender making such Loans or such portions of Loans would have had under this Agreement and otherwise; provided that (1) its voting rights under this Agreement shall be exercised solely by its Granting Lender and (2) its Granting Lender shall remain solely responsible to the other parties hereto for the performance of such SPFV’s obligations under this Agreement, including its obligations in respect of the Loans or portions of Loans made by it. No additional promissory notes, if any, shall be required to evidence the Loans or portions of Loans made by a SPFV, and the Granting Lender shall be deemed to hold its promissory note, if any, as agent for its SPFV to the extent of the Loans or portions of Loans funded by such SPFV. Each Granting Lender shall act as administrative agent for its SPFV and give and receive notices and other communications on its behalf. Any payments for the account of any SPFV shall be paid to its Granting Lender as administrative agent for such SPFV, and neither a Credit Party nor the Administrative Agent shall be responsible for any Granting Lender’s application of such payments. In furtherance of the foregoing, each party hereto hereby agrees that, until the date that is one year and one day after the payment in full of all outstanding senior Debt of any SPFV, it shall not institute against, or join any other Person in instituting against, such SPFV any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings (or any similar proceedings) under the laws of the United States of America or any State thereof. In addition, notwithstanding anything to the contrary contained in this paragraph (h), an SPFV may (1) (A) with notice to, but without the prior written consent of, the Administrative Agent or the Borrower and without paying any processing fee therefor, assign all or any portion of its interest in any Loan to its Granting Lender or (B) with the consent (which consent shall not be unreasonably withheld) of the Administrative Agent and (if no Event of Default has occurred and is continuing) the Borrower, but without paying any processing fee therefor, assign all or any portion of its interest in any Loan to any financial institution providing liquidity or credit facilities to or for the account of such SPFV to fund the Loans funded by such SPFV or to support any securities issued by such SPFV to fund such Loans, and (2) disclose, on a confidential basis, any non-public information relating to Loans funded by it to any rating agency, commercial paper dealer or provider of a surety, guaranty or credit or liquidity enhancement to such SPFV. The Borrower shall not be required to pay, or to reimburse any Granting Lender for, its expenses relating to any SPFV identified by such Granting Lender pursuant to this paragraph (h).

SECTION 11.05. Survival. All covenants, agreements, representations and warranties made by the Borrower and the 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. The provisions of Sections 2.15, 2.16, 2.17, 10.01(c)(iii) and 11.03 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the

expiration or termination of the Commitments or the termination of this Agreement or any provision hereof.

SECTION 11.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the commitment letter relating to the credit facility provided hereby (to the extent provided therein) and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 3.01, 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 11.07. 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 11.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender or any Affiliate thereof is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of any Credit Party against any of and all the Obligations 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.

SECTION 11.09. Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the laws of the State of New York.

(b) Each Credit Party hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal

court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against any Credit Party or its properties in the courts of any jurisdiction.

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

(d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 11.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 11.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 11.11. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 11.12. Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent requested by any regulatory authority; (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; (d) to any other party to this Agreement; (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder; (f) subject to an agreement containing

provisions substantially the same as those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement; (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than a Credit Party or any Subsidiary of a Credit Party. For the purposes of this Section, “Information” means all information received from any Credit Party or any Subsidiary of a Credit Party relating to a Credit Party or any Subsidiary of a Credit Party or its respective businesses, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by any Credit Party or any Subsidiary of a Credit Party; provided that, in the case of information received from any Credit Party or any Subsidiary of a Credit Party after the Effective Date, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 11.13. USA PATRIOT Act. Each Lender hereby notifies the Credit Parties 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 Credit Parties, which information includes the name and address of the Credit Parties and other information that will allow such Lender to identify the Credit Parties in accordance with the Act.

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