2.1 Revolving Credit Advances. Subject to the terms of the Existing Credit Agreement, the lenders party thereto established in favor of the Borrower, and the Lenders hereby continue, a revolving credit facility pursuant to which, upon the following terms and subject to the following conditions:

2.2 Ratable Loans. Each Revolving Credit Advance hereunder shall consist of Revolving Credit Loans made from the several Lenders ratably in proportion to the ratio that

their respective Revolving Credit Commitments bear to the Aggregate Revolving Credit Commitment.

2.3 Types of Revolving Credit Advances. The Revolving Credit Advances may be Alternate Base Rate Advances or Eurodollar Advances, or a combination thereof, selected by the Borrower in accordance with Sections 2.7 and 2.8.

2.4 Commitment Fee; Reductions in Aggregate Revolving Credit Commitment.

2.5 Optional Principal Payments. The Borrower may from time to time pay, without penalty or premium, all outstanding Alternate Base Rate Advances, or, in a minimum aggregate amount of $1,000,000 or any integral multiple of $500,000 in excess thereof, any portion of the outstanding Alternate Base Rate Advances upon two Business Days’ prior notice to the Agent. The Borrower may from time to time pay, subject to the payment of any funding indemnification amounts required by Section 4.4 but without penalty or premium, all outstanding Eurodollar Advances, or, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof, any portion of the outstanding Eurodollar Advances upon three Business Days’ prior notice to the Agent.

2.6 Mandatory Prepayments. Mandatory prepayments of Revolving Credit Loans shall be required in the amounts and at the times set forth below:

2.7 Revolving Credit Advances. The Borrower shall select the Type of Revolving Credit Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto from time to time. The Borrower shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than 10:00 a.m. (Chicago time) at least one (1) Business Day before the Borrowing Date of each Alternate Base Rate Advance and at least three (3) Business Days before the Borrowing Date for each Eurodollar Advance, specifying:

2.8 Conversion and Continuation of Outstanding Revolving Credit Advances. Alternate Base Rate Advances shall continue as Alternate Base Rate Advances unless and until such Alternate Base Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.8 or are repaid in accordance with Section 2.5. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into an Alternate Base Rate Advance unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.5 or (y) the Borrower shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. The Borrower may elect from time to time to convert all or any part of an Alternate Base Rate Advance into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of an Alternate Base Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 10:00 a.m. (Chicago time) at least three Business Days prior to the date of the requested conversion or continuation, specifying:

2.9 Changes in Interest Rate, etc. Each Alternate Base Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Revolving Credit Advance is made or is automatically converted from a Eurodollar Advance into an Alternate Base Rate Advance pursuant to Section 2.8, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.8 hereof, at a rate per annum equal to the Alternate Base Rate for such day. Changes in the rate of interest on that portion of any Revolving Credit Advance maintained as an Alternate Base Rate Advance will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate determined by the Agent as applicable to such Eurodollar Advance based upon the Borrower’s selections under Section 2.7 and 2.8 and otherwise in accordance with the terms hereof. No Interest Period may end after the Revolving Credit Termination Date.

2.10 Rates Applicable After Default. Notwithstanding anything to the contrary contained in Section 2.7 or 2.8, during the continuance of a Default or Unmatured Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 9.2 requiring unanimous consent of the Lenders to reductions in interest rates), declare that no Revolving Credit Advance may be made as, converted into or continued as a Eurodollar Advance. During the continuance of a Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 9.2 requiring unanimous consent of the Lenders to reductions in interest rates), declare that (a) each Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to such Interest Period plus 2% per annum and (b) each Alternate Base Rate Advance shall bear interest at a rate per annum equal to the Alternate Base Rate in effect from time to time plus 2% per annum, provided that, during the continuance of a Default under Section 8.6 or 8.7, the interest rates set forth in clauses (a) and (b) above shall be applicable to all Revolving Credit Advances without any election or action on the part of the Agent or any Lender.

2.11 Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Agent at the Agent’s address specified pursuant to Article XIV, or at any other Lending

Installation of the Agent specified in writing by the Agent to the Borrower, by noon (Chicago time) on the date when due and shall be applied ratably by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIV or at any Lending Installation specified in a notice received by the Agent from such Lender. The Agent is hereby authorized to charge the account of the Borrower maintained with JPMorgan Chase Bank for each payment of principal, interest and fees as it becomes due hereunder.

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

2.13 Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Revolving Credit Advances, effect selections of Types of Revolving Credit Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically.

The Borrower agrees to deliver promptly to the Agent a written confirmation, if such confirmation is requested by the Agent or any Lender, of each telephonic notice signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

2.14 Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Alternate Base Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur after the Closing Date and at maturity or, if later, upon receipt of a ▇▇▇▇ from the Agent. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period or, if later, upon receipt of a ▇▇▇▇ from the Agent. Interest on Eurodollar Advances and fees shall be calculated for actual days elapsed on the basis of a 360-day year, and interest on Alternate Base Rate Advances shall be calculated for actual days elapsed on the basis of a 365 or 366 day year, as applicable. Interest shall be payable for the day a Revolving Credit Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (Chicago time) at the place of payment. If any payment of principal of or interest on a Revolving Credit Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment. Accrued and unpaid interest under the Existing Credit Agreement shall be paid on the Closing Date.

2.15 Notification of Revolving Credit Advances, Interest Rates and Prepayments, Commitment Reductions. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate Revolving Credit Commitment reduction notice, Borrowing Notice, Conversion/Continuation Notice and repayment notice received by it hereunder. The Agent will notify each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate.

2.16 Lending Installations. Each Lender may book its Revolving Credit Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Revolving Credit Loans and any Revolving Credit Notes issued hereunder shall be deemed held by each Lender for the benefit of such Lending Installation. Each Lender may, by written notice to the Agent and the Borrower in accordance with Article XIV, designate replacement or additional Lending Installations through which Revolving Credit Loans will be made by it and for whose account Revolving Credit Loan payments are to be made.

2.17 Non-Receipt of Funds by the Agent. Unless the Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make

payment to the Agent of (a) in the case of a Lender, the proceeds of a Revolving Credit Loan or (b) in the case of the Borrower, a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to (i) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Revolving Credit Loan or (ii) in the case of payment by the Borrower, the interest rate applicable to the relevant Revolving Credit Loan.

3.1 Issuance of Letters of Credit. (a) From and after the date hereof to but excluding the Letter of Credit Availability Termination Date, the Issuer agrees, upon the terms and conditions set forth in this Agreement, to issue at the request and for the account of the Borrower, one or more Letters of Credit for the account of the Borrower (x) to support the obligations of Wholly-Owned Subsidiaries of the Borrower with respect to specific syndicates at the Society of Lloyd’s (the Letters of Credit issued under this clause (x) being called the “Lloyd’s Letters of Credit”) and (y) to support other obligations, provided that the aggregate face amount of all outstanding Letters of Credit Obligations with respect to this clause (y) does not at any time exceed the lesser of (A) the Letter of Credit Commitment and (B) $5,000,000; provided, however, that the Issuer shall not be under any obligation to issue, and shall not issue, any Letter of Credit if: (i) any order, judgment or decree of any governmental authority or other regulatory body with jurisdiction over the Issuer shall purport by its terms to enjoin or restrain such Issuer from issuing such Letter of Credit, or any law or governmental rule, regulation, policy, guideline or directive (whether or not having the force of law) from any governmental authority or other regulatory body with jurisdiction over the Issuer shall prohibit, or request that the Issuer refrain from, the issuance of Letters of Credit in particular or shall impose upon the Issuer with respect to any Letter of Credit any restriction or reserve or capital requirement (for which the Issuer is not otherwise compensated) or any unreimbursed loss, cost or expense which was not applicable, in effect and known to the Issuer as of the date of this Agreement and which the Issuer in good ▇▇▇▇▇ ▇▇▇▇▇ material to it; (ii) one or more of the conditions to such issuance contained in Section 5.2 is not then satisfied; or (iii) after giving effect to such issuance, the aggregate outstanding amount of the Letter of Credit Obligations would exceed the Letter of Credit Commitment. Letters of Credit shall be denominated, at the Borrower’s option, in either Dollars or Pounds.

3.2 Participating Interests. Immediately upon the issuance by the Issuer of a Letter of Credit in accordance with Section 3.5 (and with respect to the Letters of Credit identified on Schedule 3.1 hereto, upon satisfaction of the conditions set forth in Article V hereof), each Lender shall be deemed to have irrevocably and unconditionally purchased and received from the Issuer, without recourse, representation or warranty, an undivided participation interest equal to its pro-rata share of the Letter of Credit Commitment of the face amount of such Letter of Credit and each draw paid by the Issuer thereunder. Each Lender’s obligation to pay its proportionate share of all draws under the Letters of Credit, absent gross negligence or willful misconduct by the Issuer in honoring any such draw, shall be absolute, unconditional and irrevocable and in each case shall be made without counterclaim or set-off by such Lender.

3.3 Reductions in Letter of Credit Commitment. The Borrower may permanently reduce the Letter of Credit Commitment in whole, or in part ratably among the Lenders in integral multiples of $2,500,000, upon at least five (5) Business Days’ written notice to the Agent, which notice shall specify the amount of such reduction; provided, however, that the amount of the Letter of Credit Commitment may not be reduced below the aggregate amount of the outstanding Letter of Credit Obligations.

3.4 Reimbursement Obligations. (a) The Borrower agrees to pay to the Issuer of a Letter of Credit (i) on each date that any amount is drawn under each Letter of Credit (or, if any draw is paid by the Issuer after 3:00 p.m. (Chicago time) on such date, on the next succeeding Business Day) a sum (and interest on such sum as provided in clause (ii) below) equal to the amount so drawn plus all other charges and expenses with respect thereto specified in Section 3.9 or in the applicable Reimbursement Agreement and (ii) interest on any and all amounts remaining unpaid under this Section 3.4 until payment in full at the rate per annum, computed for actual days elapsed based on a 365 or 366 day year, as applicable, equal to (A) the Alternate Base Rate for such day for the first two days following the due date of any Reimbursement Obligations, and (B) the Alternate Base Rate for such day plus 2% per annum. The Borrower agrees to pay to the Issuer the amount of all Reimbursement Obligations owing in respect of any Letter of Credit immediately when due, under all circumstances, including, without limitation, any of the following circumstances: (w) any lack of validity or enforceability of this Agreement or any of the other Facility Documents; (x) the existence of any claim, set-off, defense or other right which the Borrower may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), any Lender or any other

Person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrower and the beneficiary named in any Letter of Credit); (y) the validity, sufficiency or genuineness of any document which the Issuer has determined in good faith complies on its face with the terms of the applicable Letter of Credit, even if such document should later prove to have been forged, fraudulent, invalid or insufficient in any respect or any statement therein shall have been untrue or inaccurate in any respect; or (z) the surrender or impairment of any security for the performance or observance of any of the terms hereof.

3.5 Procedure for Issuance. Prior to the issuance of each new Letter of Credit, and as a condition of such issuance, the Borrower shall deliver to the Issuer (with a copy to the Agent) a Reimbursement Agreement signed by the Borrower, together with such other documents or items as may be required pursuant to the terms thereof, and the proposed form and content of such Letter of Credit shall be reasonably satisfactory to the Issuer. Each Letter of Credit shall be issued no earlier than two (2) Business Days after delivery of the foregoing documents, which delivery may be by the Borrower to the Issuer by telecopy, telex or other electronic means followed by delivery of executed originals within five (5) days thereafter. The documents so delivered shall be in compliance with the requirements set forth in Section 3.1(b), and shall specify therein (a) the stated amount of the Letter of Credit requested, (b) the effective date of issuance of such requested Letter of Credit, which shall be a Business Day, (c) the date on which such requested Letter of Credit is to expire, which shall be no later than four years from the date of issuance of such Letter of Credit or in the case of a Lloyd’s Letter of Credit, four years from notice of expiry from the Issuer to the Borrower and the beneficiary of such Letter of Credit, (d) whether the Letter of Credit is to be denominated in Dollars or Pounds, and (e) the aggregate amount of Letter of Credit Obligations which are outstanding and which will be outstanding after giving effect to the

requested Letter of Credit issuance. The delivery of the foregoing documents and information shall constitute an “Issuance Request” for purposes of this Agreement. Subject to the terms and conditions of Section 3.1 and provided that the applicable conditions set forth in Section 5.2 hereof have been satisfied, the Issuer shall, on the requested date, issue a Letter of Credit on behalf of the Borrower in accordance with the Issuer’s usual and customary business practices. In addition, any amendment of an existing Letter of Credit shall be deemed to be an issuance of a new Letter of Credit and shall be subject to the requirements set forth above. The Issuer shall give the Agent prompt written notice of the issuance of any Letter of Credit.

3.6 Nature of the Lenders’ Obligations. (a) As between the Borrower and the Lenders, the Borrower assumes all risks of the acts and omissions of, or misuse of the Letters of Credit by, the respective beneficiaries of the Letters of Credit; provided, however, that the Borrower may have a claim against the Issuer, and the Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct (as opposed to consequential or exemplary) damages suffered by the Borrower which the Borrower proves were caused by the Issuer’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Lenders shall not be responsible for: (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for an issuance of a Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) the failure of the beneficiary of a Letter of Credit to comply fully with conditions required to be satisfied by any Person other than the Issuer in order to draw upon such Letter of Credit; (iv) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise; (v) errors in the interpretation of technical terms; (vi) the misapplication by the beneficiary of a Letter of Credit of the proceeds of any drawing under such Letter of Credit; or (vii) any consequences arising from causes beyond control of the Issuer.

3.7 Notification of Issuance Requests. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Issuance Request received by it hereunder.

3.8 Cash Collateral for Letters of Credit. If no Cash Collateral Security Agreement has been previously entered into, then on the Letter of Credit Availability Termination Date

the Borrower shall enter into the Cash Collateral Security Agreement and, in any event, on and after such date the Borrower shall pledge and deliver to the Agent, for the benefit of the Lenders, cash or Cash Collateral Investments in sufficient amounts to maintain in the Letter of Credit Cash Collateral Account an amount at least equal to the following percentage of the Letter of Credit Obligations outstanding from time to time during the following periods:

3.9 Fees.

3.10 Extension of Revolving Credit Termination Date. The Borrower may request an extension of the Letter of Credit Availability Termination Date and the Revolving Credit Termination Date by submitting a request for an extension to the Agent (an “Extension Request”) on any Business Day that is not less than 30 days prior to the then Letter of Credit Availability Termination Date or Revolving Credit Termination Date. The Extension Request must specify the new Letter of Credit Availability Termination Date or new Revolving Credit Termination Date requested by the Borrower and the date as of which date (which must be at least 30 days after the Extension Request is delivered to the Agent) the Lenders (including the Issuer) must respond to the Extension Request (the “Response Date”). The new Letter of Credit Availability Termination Date or new Revolving Credit Termination Date shall not be more than two years after the Letter of Credit Availability Termination Date or Revolving Credit Termination Date, as applicable, in effect at the time the Extension Request is received, including the Letter of Credit Availability Termination

Date or Revolving Credit Termination Date as one of the days in the calculation of the days elapsed. Promptly upon receipt of an Extension Request, the Agent shall notify each Lender of the contents thereof and shall request the Issuer and each Lender to approve the Extension Request. Each Lender approving the Extension Request shall deliver its written consent no later than the Response Date. If the consent of all of the Lenders in their sole discretion is received by the Agent, the Letter of Credit Availability Termination Date or Revolving Credit Termination Date specified in the Extension Request shall become effective on the existing Letter of Credit Availability Termination Date or Revolving Credit Termination Date and the Agent shall promptly notify the Borrower and each Lender (including the Issuer) of the new Letter of Credit Availability Termination Date and the new Revolving Credit Termination Date. Otherwise the Letter of Credit Availability Termination Date or Revolving Credit Termination Date shall be unchanged.

4.1 Yield Protection. If, on or after the Closing Date, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

4.2 Changes in Capital Adequacy Regulations. If a Lender determines the amount of capital required or expected to be maintained by such Lender, any Lending Installation of such Lender or any corporation controlling such Lender is increased as a result of a Change, then, within 15 days of demand by such Lender, the Borrower shall pay such Lender the amount necessary to compensate for any shortfall in the rate of return on the portion of such

increased capital which such Lender determines is attributable to this Agreement, its Revolving Credit Loans, its Revolving Credit Commitment to make Revolving Credit Loans or its commitment to participate in Letters of Credit hereunder (after taking into account such Lender’s policies as to capital adequacy). “Change” means (a) any change after the Closing Date in the Risk-Based Capital Guidelines or (b) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the Closing Date which affects the amount of capital required or expected to be maintained by any Lender or any Lending Installation or any corporation controlling any Lender. “Risk-Based Capital Guidelines” means (i) the risk-based capital guidelines in effect in the United States on the Closing Date, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to such regulations adopted prior to the Closing Date.

4.3 Availability of Types of Revolving Credit Advances. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Alternate Base Rate Advances, subject to the payment of any funding indemnification amounts required by Section 4.4.

4.4 Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made on the date specified by the Borrower for any reason other than default by the Lenders, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance.

4.5 Taxes. (a) All payments by the Borrower to or for the account of any Lender or the Agent hereunder or under any Revolving Credit Note shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender or the Agent, (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 4.5) such Lender or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (iv) the Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof within thirty (30) days after such payment is made.

4.6 Lender Statements; Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 4.1, 4.2 and 4.5 or to avoid the unavailability of Eurodollar Advances under Section 4.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 4.1, 4.2, 4.4 or 4.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Revolving Credit Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 4.1, 4.2, 4.4 and 4.5 shall survive payment of the Obligations and termination of this Agreement.

5.1 Initial Revolving Credit Loans and Letters of Credit. The amendments to the Existing Credit Agreement embodied in this Agreement shall not be effective (in which case the Existing Credit Agreement shall remain in full force and effect) and the Lenders shall have no obligation to make Revolving Credit Advances hereunder and the Issuer shall have no obligation to issue any Letter of Credit hereunder unless and until all loans under the Existing Credit Agreement have been paid in full and the Borrower has furnished the following to the Agent with sufficient copies for the Lenders and the other conditions set forth below have been satisfied:

5.2 Each Revolving Credit Advance and Letter of Credit. The Lenders shall not be required to make any Revolving Credit Advance (other than a Revolving Credit Advance that, after giving effect thereto and to the application of the proceeds thereof, does not increase the aggregate amount of outstanding Revolving Credit Advances), and the Issuer shall not be obligated to issue any Letter of Credit, unless on the applicable Borrowing Date:

6.1 Existence and Standing. Each of the Borrower and its Subsidiaries is a corporation, duly and properly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted.

6.2 Authorization and Validity. The Borrower has the corporate power and authority and legal right to execute and deliver the Facility Documents and to perform its obligations thereunder. The execution and delivery by the Borrower of the Facility Documents and the performance of its obligations thereunder have been duly authorized by proper corporate proceedings, and the Facility Documents to which the Borrower is a party constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally.

6.3 No Conflict; Government Consent. Neither the execution and delivery by the Borrower of the Facility Documents, nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof will violate (a) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of its Subsidiaries or (b) the Borrower’s or any Subsidiary’s articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (c) the provisions of any indenture, instrument or agreement to which the Borrower or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder, or result in, or require, the creation or imposition of any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the terms of any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Borrower or any of its Subsidiaries, is required to be obtained by the Borrower or any of its Subsidiaries in connection with the execution and delivery of the Facility Documents, the extensions of credit under this Agreement, the payment and performance by the Borrower of the Obligations or the legality, validity, binding effect or enforceability of any of the Facility Documents, except that approval of the New York Insurance Department, the California Insurance Department and/or one or more other state insurance departments would be required in order for the Lenders to acquire control of Navigators and NSIC. Neither the Borrower nor any Subsidiary is in default under or in violation of any foreign, federal, state or local law, rule, regulation, order, writ, judgment, injunction, decree or award binding upon or applicable to the Borrower or such Subsidiary, in each case the consequences of which default or violation could reasonably be expected to have a Material Adverse Effect.

6.4 Financial Statements. (a) The consolidated balance sheets of the Borrower and the Consolidated Subsidiaries as of December 31, 2005 the related consolidated statements of income, consolidated statements of stockholders’ equity, and consolidated statements of cash flows of the Borrower and such Consolidated Subsidiaries for the Fiscal Year then ended, and the accompanying footnotes, together, with the opinion thereon, of KPMG Peat Marwick, independent certified public accountants, copies of which have been furnished to the Lenders, fairly present the financial condition of the Borrower and the Consolidated Subsidiaries as at such dates and the results of the operations of the Borrower and

9.3 Preservation of Rights. No delay or omission of the Lenders or the Agent to exercise any right under the Facility Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Revolving Credit Loan or the issuance of a Letter of Credit notwithstanding the existence of a Default or the

inability of the Borrower to satisfy the conditions precedent to such Revolving Credit Loan or Letter of Credit shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Facility Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 9.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Facility Documents or by law afforded shall be cumulative and all shall be available to the Agent and the Lenders until the Obligations have been paid in full.

10.1 Survival of Representations. All representations and warranties of the Borrower contained in this Agreement or in any Facility Document shall survive the making of the Revolving Credit Loans and the issuance of the Letters of Credit herein contemplated.

10.2 Governmental Regulation. Anything contained in this Agreement to the contrary notwithstanding, no Lender shall be obligated to extend credit to the Borrower in violation of any limitation or prohibition provided by any applicable statute or regulation.

10.3 Headings. Section headings in the Facility Documents are for convenience of reference only, and shall not govern the interpretation of any of the provisions of the Facility Documents.

10.4 Entire Agreement. The Facility Documents embody the entire agreement and understanding among the Borrower, the Agent, and the Lenders and supersede all prior agreements and understandings among the Borrower, the Agent, and the Lenders relating to the subject matter thereof other than the fee letter dated December 14, 2006 in favor of JPMorgan Chase Bank and JPMorgan Securities Inc. (the “Fee Letter”).

10.5 Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each of the Lenders.

10.6 Several Obligations; Benefits of this Agreement. The respective obligations of the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). The failure of any Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of its obligations hereunder. This Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns, provided, however, that the parties hereto expressly agree that the Arranger shall enjoy the benefits of the provisions of Sections 10.7, 10.11 and 11.11 to the extent specifically set forth therein and shall have the right to

enforce such provisions on its own behalf and in its own name to the same extent as if it were a party to this Agreement.

10.7 Expenses; Indemnification. (a) The Borrower shall reimburse the Agent and the Arranger for any costs, internal charges and out-of-pocket expenses (including reasonable attorneys’ fees and time charges of attorneys for the Agent) paid or incurred by the Agent or the Arranger in connection with the preparation, negotiation, execution, delivery, syndication, review, amendment, modification, and administration of the Facility Documents. The Borrower also agrees to reimburse the Agent, the Arranger and the Lenders for any costs, internal charges and out-of-pocket expenses (including reasonable attorneys’ fees and time charges of attorneys for the Agent, the Arranger and the Lenders), paid or incurred by the Agent, the Arranger or any Lender in connection with the investigation, collection and enforcement of the Facility Documents.

10.8 Accounting. Except as provided to the contrary herein, all accounting terms used herein shall be interpreted and all accounting determinations hereunder shall be made in accordance with Agreement Accounting Principles. In the event the pages, columns, lines or sections of the Annual Statement referenced herein are changed or renumbered, all such references shall be deemed references to such page, column, line or section as so renumbered or changed.

10.9 Severability of Provisions. Any provision in any Facility Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of all Facility Documents are declared to be severable.

10.10 Nonliability of Lenders. The relationship between the Borrower on the one hand and the Lenders and the Agent on the other hand shall be solely that of borrower and lender. Neither the Agent, the Arranger nor any Lender shall have any fiduciary responsibilities to the Borrower. Neither the Agent, the Arranger nor any Lender undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in

connection with any phase of the Borrower’s business or operations. The Borrower agrees that neither the Agent, the Arranger nor any Lender shall have liability to the Borrower (whether sounding in tort, contract or otherwise) for losses suffered by the Borrower in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Facility Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. Neither the Agent, the Arranger nor any Lender shall have any liability with respect to, and the Borrower hereby waives, releases and agrees not to ▇▇▇ for, any special, indirect, punitive or consequential damages suffered by the Borrower in connection with, arising out of, or in any way related to the Facility Documents or the transactions contemplated thereby.

10.11 Confidentiality. Each Lender agrees to hold any confidential information which it may receive from the Borrower pursuant to this Agreement in confidence, except for disclosure (a) to its Affiliates and to other Lenders and their respective Affiliates, (b) to legal counsel, accountants, and other professional advisors to such Lender or to a Transferee, (c) to regulatory officials, (d) to any Person as requested pursuant to or as required by law, regulation, or legal process, (e) to any Person in connection with any legal proceeding to which such Lender is a party, (f) to such Lender’s direct or indirect contractual counterparties in swap agreements or to legal counsel, accountants and other professional advisors to such counterparties and (g) permitted by Section 13.4; provided, that any recipient of such disclosure shall be advised by such Lender of the confidentiality requirements herein set forth.

10.12 Nonreliance. Each Lender hereby represents that it is not relying on or looking to any margin stock (as defined in Regulation U of the Board of Governors of the Federal Reserve System) for the repayment of the Revolving Credit Loans provided for herein.

10.13 Disclosure. The Borrower and each Lender hereby (a) acknowledge and agree that JPMorgan Chase Bank and/or its Affiliates from time to time may hold other investments in, make other loans to or have other relationships with the Borrower, and (b) waive any liability of JPMorgan Chase Bank or such Affiliate to the Borrower or any Lender, respectively, arising out of or resulting from such investments, loans or relationships other than liabilities arising out of the gross negligence or willful misconduct of JPMorgan Chase Bank or its Affiliates.

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

(a) From and including the date hereof to but excluding the Revolving Credit Termination Date, each Lender severally (and not jointly) agrees, on the terms and conditions set forth in this Agreement, to make Revolving Credit Loans to the Borrower from time to time in amounts not to exceed in the aggregate at any one time outstanding the amount of its pro-rata share of the Aggregate Revolving Credit Commitment existing at such time. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Revolving Credit Advances at any time prior to the Revolving Credit Termination Date. The Revolving Credit Commitments shall expire on the Revolving Credit Termination Date. All Revolving Credit Loans shall be in Dollars.

(b) The Borrower hereby agrees that, if at any time as a result of reductions in the Aggregate Revolving Credit Commitment pursuant to Section 2.4(b) or otherwise, the aggregate balance of the Revolving Credit Loans exceeds the Aggregate Revolving Credit Commitment, the Borrower shall repay immediately such then amount of Revolving Credit Loans as may be necessary to eliminate such excess.

(c) Any outstanding Revolving Credit Advances and all other unpaid Obligations with respect to the Revolving Credit Loans shall be paid in full by the Borrower on the Revolving Credit Termination Date.

(d) Upon the effectiveness of this Agreement pursuant to Section 5.1, each Revolving Credit Advance which is then outstanding under the Existing Credit Agreement shall be deemed a Revolving Credit Advance outstanding under this Agreement.

(a) The Borrower agrees to pay to the Agent for the account of each Lender a commitment fee on its Revolving Credit Commitment less its Revolving Credit Loans at a per annum rate equal to the Applicable Commitment Fee Rate from the Closing Date to and including the Revolving Credit Termination Date, payable on each Payment Date hereafter and on the Revolving Credit Termination Date or, if later, upon receipt of a ▇▇▇▇ from the Agent. All such accrued commitment fees shall be payable on the effective date of any termination of the obligations of the Lenders to make Revolving Credit Loans hereunder or, if later, upon receipt of a ▇▇▇▇ from the Agent. Accrued and unpaid commitment fees under the Existing Agreement shall be paid on the Closing Date.

(b) The Borrower may permanently reduce the Aggregate Revolving Credit Commitment in whole, or in part ratably among the Lenders in integral multiples of $5,000,000 upon at least five (5) Business Days’ written notice to the Agent, which notice shall specify the amount of any such reduction; provided, however, that the amount of the Aggregate Revolving Credit Commitment may not be reduced below the aggregate principal amount of the outstanding Revolving Credit Loans.

(a) concurrently with the receipt thereof by the Borrower or any Subsidiary, 75% of the aggregate Net Available Proceeds in excess of $1,000,000 realized upon all Asset Dispositions in any Fiscal Year; and

(b) concurrently with the receipt thereof by the Borrower or any Subsidiary, 75% of the Net Available Proceeds in excess of $1,000,000 realized upon the issuance or

sale by the Borrower or such Subsidiary of any equity or debt securities (other than an issuance or sale of common stock of a Subsidiary to the Borrower);

(a) the Borrowing Date of such Revolving Credit Advance, which shall be a Business Day;

(b) the aggregate amount of such Revolving Credit Advance;

(c) the Type of Revolving Credit Advance selected; and

(d) in the case of each Eurodollar Advance, the Interest Period applicable thereto, which shall end on or prior to the Revolving Credit Termination Date.

(a) the requested date, which shall be a Business Day, of such conversion or continuation,

(b) the aggregate amount and Type of the Revolving Credit Advance which is to be converted or continued, and

(c) the amount of such Revolving Credit Advance which is to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto.

(b) The Agent shall also maintain accounts in which it will record (i) the amount of each Revolving Credit Loan made hereunder, the Type thereof and the Interest Period with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Agent hereunder from the Borrower and each Lender’s share thereof.

(c) The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(d) Any Lender may request that its Revolving Credit Loans be evidenced by a promissory note in the form of Exhibit A (a “Revolving Credit Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender a Revolving Credit Note payable to the order of such Lender. Thereafter, the Revolving Credit Loans evidenced by such Revolving Credit Note and interest thereon shall at all times (including after any assignment pursuant to Section 13.3) be represented by one or more Revolving Credit Notes payable to the order of the payee named therein or any assignee pursuant to Section 13.3, except to the extent that any such Lender or assignee subsequently returns any such Revolving Credit Note for cancellation and requests that such Revolving Credit Loans once again be evidenced as described in paragraphs (a) and (b) above.

(b) In no event shall: (i) the aggregate amount of the Letter of Credit Obligations at any time exceed the Letter of Credit Commitment; or (ii) the expiration date of any Letter of Credit (other than the Letters of Credit identified on Schedule 3.1 hereto) or the date for payment of any draft presented thereunder and accepted by the Issuer, be later than (x) the date one year after the effective date of such Letter of Credit or (y) in the case of the Lloyd’s Letters of Credit, four years after notice of expiry from the Issuer to the Borrower and the beneficiary of the Letter of Credit; provided, that each Letter of Credit issued with an automatic “evergreen” provision providing for renewal absent advance notice by the Borrower or the Issuer shall be automatically renewed unless at least 30 days prior to each anniversary of the issuance of such Letter of Credit the beneficiary thereof receives notice from the Issuer that such Letter of Credit shall not be renewed. The Issuer shall be under no obligation to permit the renewal or extension of any Letter of Credit at any time (A) when a Default or Unmatured Default has occurred and is continuing or (B) after the Letter of Credit Availability Termination Date. The Issuer may (and, upon the request of the Required Lenders, shall) give notice of termination of any Lloyd’s Letters of Credit with an expiry date based upon notice at any time (A) when a Default has occurred and is continuing or (B) after the Letter of Credit Availability Termination Date.

(c) The Borrower agrees that, if at any time as a result of reductions in the Letter of Credit Commitment pursuant to Section 3.3 or otherwise the aggregate balance of the Letter of Credit Obligations exceeds the Letter of Credit Commitment, the Borrower shall cash collateralize the Letter of Credit Obligations by depositing into the Letter of Credit Cash Collateral Account cash or Cash Collateral Investments in such amount as may be necessary to eliminate such excess.

(d) The Letters of Credit identified on Schedule 3.1 hereto which are issued and outstanding under the Existing Credit Agreement shall, upon satisfaction of the conditions set forth in Article V hereto, automatically and without further action on the part of the Agent, the Issuer, the Lenders or the Borrower be deemed Letters of Credit issued under this Agreement.

(e) For purposes of determining usage and availability under this Section 3.1, when a Letter of Credit is issued in Pounds, such Pounds will be converted to Dollars upon issuance, upon the proposed issuance of any other Letter of Credit and at the end of each calendar quarter, and at any time thereafter as requested by the Agent or any Lender (including the Issuer) and such determination shall be made by the Agent in its sole determination based upon the spot exchange rate between Dollars and Pounds as quoted by the Agent’s foreign exchange desk as of such date of determination. Notwithstanding any other provisions of this Agreement, if at any time, after giving effect to the conversion of Pounds into Dollars as set forth above, the aggregate face amount of all outstanding Letters of Credit is greater than the Letter of Credit Commitment (“Conversion Differential”), then the Borrower shall cash collateralize such Conversion Differential by depositing into the Letter of Credit Cash Collateral Account cash or Cash Collateral Investments in an amount equal to such difference.

(f) At the request of the Borrower, Letters of Credit may be issued with any Wholly-Owned Subsidiary of the Borrower as an applicant, so long as the Borrower is also an applicant under the applicable Reimbursement Agreement. The fact that such Subsidiary is an applicant shall not affect the obligations of the Borrower with respect to such Letters of Credit hereunder or under any Facility Document in any way. Any Reimbursement Agreement for a Letter of Credit with respect to which such Subsidiary is an applicant shall include language substantially similar to that set forth in Exhibit D or otherwise acceptable to the Agent.

(b) Notwithstanding any provisions to the contrary in any Reimbursement Agreement, the Borrower agrees to reimburse the Issuer for amounts which the Issuer pays under such Letter of Credit no later than the time specified in this Agreement. If the Borrower does not pay any such Reimbursement Obligations when due at any time prior the Revolving Credit Termination Date, such Reimbursement Obligations, if in Pounds, shall be deemed to have been converted into the equivalent amount of Dollars on the date due based upon the spot rate of exchange between Dollars and Pounds as determined by the Agent on the Reuters WRLD Page as of the time of determination on such date. In the event that such rate does not appear on any Reuters WRLD Page, the exchange rate shall be determined by reference to such other publicly available service for displaying exchange rates as may be agreed upon by the Agent and the Borrower, or, in the absence of such an agreement, such exchange rate shall instead be the arithmetic average of the spot rates of exchange of the Agent in London at or about such time between Dollars and Pounds for delivery two Business Days later; provided that if at the time of any such determination, for any reason, no such spot rate is being quoted, the Agent may use any reasonable method it deems appropriate to determine such rate, and such determination shall be presumed correct absent manifest error.

(c) If the Issuer makes a payment on account of any Letter of Credit and is not concurrently reimbursed therefor by the Borrower, then as promptly as practical during normal banking hours on the date of its receipt of such notice or, if not practicable on such date, not later than noon (Chicago time) on the Business Day immediately succeeding such date of notification, each Lender shall deliver to the Agent for the account of the Issuer, in immediately available funds, the purchase price for such Lender’s interest in such unreimbursed Reimbursement Obligations, which shall be an amount equal to such Lender’s pro-rata share of such payment. Each Lender shall, upon demand by the Issuer, pay the Issuer interest on such Lender’s pro-rata share of such draw from the date of payment by the Issuer on account of such Letter of Credit until the date of delivery of such funds to the Issuer by such Lender at a rate per annum, computed for actual days elapsed based on a 360-day year, equal to the Federal Funds Effective Rate on the amount of the unreimbursed Reimbursement Obligations, if in Dollars, or the equivalent amount of Dollars calculated in the manner provided in paragraph (b), if in Pounds, for such period; provided, that such payments shall be made by the Lenders only in the event and to the extent that the Issuer is not reimbursed in full by the Borrower for interest on the amount of any draw on the Letters of Credit.

(d) At any time after the Issuer has made a payment on account of any Letter of Credit and has received from any other Lender such Lender’s pro-rata share of such payment, such Issuer shall, forthwith upon its receipt of any reimbursement (in whole or in part) by the Borrower for such payment, or of any other amount from the Borrower or any other Person in respect of such payment (including, without limitation, any payment of interest or penalty fees and any payment under any collateral account agreement of the Borrower or any Facility Document but excluding any transfer of funds from any other Lender pursuant to Section 3.4(b)), transfer to such other Lender such other Lender’s ratable share of such reimbursement or other amount; provided, that interest shall accrue for the benefit of such Lender from the time such Issuer has made a payment on account of any Letter of Credit; provided, further, that in the event that the receipt by the Issuer of such reimbursement or other amount is found to have been a transfer in fraud of creditors or a preferential payment under the United States Bankruptcy Code or is otherwise required to be returned, such Lender shall promptly return to the Issuer any portion thereof previously transferred by the Issuer to such Lender, but without interest to the extent that interest is not payable by the Issuer in connection therewith.

(e) All payments in respect of Reimbursement Obligations shall be in Dollars at the Issuer’s selling rate for cable transfers to the place of payment of the Letter of Credit current on the date of payment or of the Issuer’s settlement of its obligation, as the Issuer may require or, at the Issuer’s election, in the currency in which the Issuer was required to pay such Letter of Credit. If, for any cause, on the date of payment or settlement, as the case may be, there is no selling rate or other rate of exchange generally current in Chicago for effecting such transfers, the Borrower will pay the Issuer on demand an amount in Dollars equivalent to the Issuer’s actual cost of settlement on its obligation however or whenever the Issuer shall make such settlement, with interest at the Alternate Base Rate from the date of settlement to the date of payment.

(b) In furtherance and extension and not in limitation of the specific provisions hereinabove set forth, any action taken or omitted by the Issuer under or in connection with the Letters of Credit or any related certificates, if taken or omitted in good faith, shall not put the Agent or any Lender under any resulting liability to the Borrower or relieve the Borrower of any of its obligations hereunder to the Issuer or any such Person.

(a) Commitment Fee. The Borrower agrees to pay to the Agent for the account of each Lender with respect to its Letter of Credit Participation Amount a commitment fee at a rate per annum equal to the Applicable Commitment Fee Rate on the daily unused portion of such Lender’s Letter of Credit Participation Amount from the Closing Date to and including the Letter of Credit Availability Termination Date, payable on each Payment Date hereafter and on the Letter of Credit Availability Termination Date or, if later, upon receipt of a ▇▇▇▇ from the Agent. Accrued and unpaid commitment fees under the Existing Credit Agreement shall be paid on the Closing Date or, if later, upon receipt of a ▇▇▇▇ from the Agent.

(b) Letter of Credit Fronting Fee. The Borrower hereby agrees to pay to the Agent, for the account of the Issuer, a letter of credit fronting fee with respect to each Letter of Credit from and including the date of issuance thereof (or, with respect to the Letters of Credit identified on Schedule 3.1, the date on which such Letters of Credit are deemed issued under this Agreement pursuant to Section 3.1(d)) until the date such Letter of Credit is fully drawn, canceled or expired, in an amount equal to the rate provided in the Fee Letter of the aggregate initial face amount of such Letter of Credit, calculated with respect to actual days elapsed on the basis of a 360-day year and payable quarterly in arrears on each Payment Date in each year and upon the expiration, cancellation or utilization in full of such Letter of Credit. In addition to the foregoing, the Borrower agrees to pay the Issuer any other fees customarily charged by it in respect of the issuance, amendment, cancellation, negotiation or transfer of each Letter of Credit and each drawing made thereunder. The letter of credit fronting fee is in addition to (and not included in) the letter of credit participation fee provided for in paragraph (c) below. Accrued and unpaid fronting fees under the Existing Credit Agreement shall be paid on the Closing Date or, if later, upon receipt of a ▇▇▇▇ from the Agent.

(c) Letter of Credit Participation Fee. The Borrower agrees to pay to the Agent for the pro-rata account of the Lenders (including the Issuer) a letter of credit participation fee with respect to each Letter of Credit from and including the date of issuance thereof until the date such Letter of Credit is fully drawn, canceled or expired, in an amount equal to the Applicable Letter of Credit Participation Fee Rate on the aggregate amount from time to time available to be drawn on such Letter of Credit, calculated with respect to actual days elapsed on the basis of a 360-day year and payable quarterly in arrears on each Payment Date in each year and upon the expiration, cancellation or utilization in full of such Letter of Credit. During the continuance of a Default, the Required Lenders may, at their option, by notice to the Borrower, declare that the Applicable Letter of Credit Participation Fee Rate shall be increased by 2% per annum; provided, that during the continuance of a Default under Section 8.6 or 8.7, the Applicable Letter of Credit Participation Fee Rate shall be increased by 2% without any election or action on the part of the Agent or any Lender.

(a) subjects any Lender or any applicable Lending Installation to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender in respect of its Eurodollar Loans or its interest in the Letters of Credit, or

(b) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

(c) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation of making, funding or maintaining its Eurodollar Loans or issuing Letters of Credit or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with its Eurodollar Loans or any Letter of Credit, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Eurodollar Loans held, Letters of Credit issued or participated in or interest received by it, by an amount deemed material by such Lender,

(b) In addition, the Borrower hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Revolving Credit Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Revolving Credit Note (“Other Taxes”).

(c) The Borrower hereby agrees to indemnify the Agent and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 4.5) paid by the Agent or such Lender and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within thirty (30) days of the date the Agent or such Lender makes demand therefor pursuant to Section 4.6.

(d) Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a “Non-U.S. Lender”) agrees that it will, not less than ten (10) Business Days after the date of this Agreement, (i) deliver to each of the Borrower and the Agent such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower, certifying that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. Each Non-U.S. Lender further undertakes to deliver to each of the Borrower and the Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

(e) For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to paragraph (d) above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Lender shall not be entitled to indemnification under this Section 4.5 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. Lender which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under paragraph (d) above, the Borrower shall take such

steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes.

(f) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Revolving Credit Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate.

(g) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under this Section 4.5(g) shall survive the payment of the Obligations and termination of this Agreement.

The Letter of Credit Cash Collateral Account shall be maintained by JPMorgan Chase Bank in the name of the Agent for the ratable benefit of the Lenders and the Agent pursuant to the terms of Article IX; provided, however, that if no Default has occurred and is continuing, the Borrower may direct the investment of funds therein in Cash Collateral Investments. The earnings thereon shall be for the account of the Borrower.

3.11 Optional Increase in Letter of Credit Commitment. The Borrower may, from time to time, by means of a letter delivered to the Agent substantially in the form of Exhibit E, request that the Letter of Credit Commitment be increased by an aggregate amount (for all such increases) not exceeding $20,000,000 by (a) increasing the Letter of Credit Participation Amount of one or more Lenders that have agreed to such increase (in their sole discretion) and/or (b) adding one or more commercial banks or other Persons as a party hereto (each an “Additional Lender”) with a Letter of Credit Participation Amount in an amount agreed to by any such Additional Lender; provided that (i) any increase in the Letter of Credit Commitment shall be in an aggregate amount of $1,000,000 or a higher integral multiple of $1,000,000; (ii) no Additional Lender shall be added as a party hereto without the written consent of the Agent and the Issuer (which consents shall not be unreasonably withheld) or if a Default or an Unmatured Default exists; and (iii) the Borrower may not request an increase in the Letter of Credit Commitment unless the Borrower has delivered to the Agent (with a copy for each Lender) a certificate stating that the representations and warranties contained in Article VI are correct on and as of the date of such certificate as though made on and as of such date and that no Default or Unmatured Default exists on such date. Any increase in the Letter of Credit Commitment pursuant to this Section 3.11 shall be effective three Business Days after the date on which the Agent has received and accepted the applicable increase letter in the form of Annex 1 to Exhibit E (in the case of an increase in the Letter of Credit Participation Amount of an existing Lender) or assumption letter in the form of Annex 2 to Exhibit E (in the case of the addition of a commercial bank or other Person as a new Lender). The Agent shall promptly notify the Borrower and the Lenders of any increase in the Letter of Credit Commitment pursuant to this Section 3.11 and of the Letter of Credit Participation Amount and pro rata share of each Lender after giving effect thereto. To the extent that any increase pursuant to this Section 3.11 is not expressly authorized pursuant to resolutions or consents delivered pursuant to Section 5.1(b), the Borrower shall, prior to the effectiveness of such increase, deliver to the Agent a certificate signed by an authorized officer of the Borrower certifying and attaching the resolutions or consents that have been adopted to approve or consent to such increase.

and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation of making or maintaining its Eurodollar Loans, the Letter of Credit Commitment or Revolving Credit Commitment or its interest in the Letters of Credit or to reduce the return received by such Lender or applicable Lending Installation in connection with such Eurodollar Loans, the Letter of Credit Commitment or Revolving Credit Commitment or interest in Letters of Credit, then, within 15 days of demand by such Lender, the Borrower shall pay such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction in amount received.

Each Borrowing Notice with respect to each such Revolving Credit Advance and each Issuance Request with respect to each such Letter of Credit shall constitute a representation and warranty by the Borrower that the conditions contained in Section 5.2 (a) and (b) have been satisfied. Any Lender may require a duly completed compliance certificate in substantially the form of Exhibit B hereto as a condition to making a Revolving Credit Advance or issuing a Letter of Credit.

The Borrower represents and warrants to the Lenders that:

During the term of this Agreement, unless the Lenders shall otherwise consent in writing:

The Borrower may provide information required under Sections 7.1(a), (b), (k), and (l) by posting such information on ▇▇▇▇▇ and giving notice to the Agent of such posting.

provided that the Borrower will not, and will not permit any Subsidiary to, make any Investments not in conformity with its then applicable investment guidelines.

The occurrence of any one or more of the following events shall constitute a Default:

If, within thirty (30) days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Revolving Credit Loans and/or issue Letters of Credit hereunder as a result of any Default (other than any Default as described in Section 8.6 or 8.7 with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in

their sole discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

provided, further, that no such supplemental agreement shall, without the consent of each Lender, amend this Section 9.2. No amendment of any provision of this Agreement relating to the Agent shall be effective without the written consent of the Agent. The Agent may waive payment of the fee required under Section 13.3.2 without obtaining the consent of any other party to this Agreement.

ARTICLE XI

THE ADMINISTRATIVE AGENT

11.1 Appointment; Nature of Relationship. JPMorgan Chase Bank is hereby appointed by each of the Lenders as Administrative Agent (herein referred to as the “Agent”) hereunder and under each other Facility Document, and each of the Lenders irrevocably authorizes the Agent to act as the Administrative Agent of such Lender with the rights and duties expressly set forth herein and in the other Facility Documents. The Agent agrees to act as such Administrative Agent upon the express conditions contained in this Article XI. Notwithstanding the use of the defined term “Agent,” it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Facility Document and that the Agent is merely acting as the Administrative Agent of the Lenders with only those duties as are expressly set forth in this Agreement and the other Facility Documents. In its capacity as the Lenders’ Administrative Agent, the Agent (a) does not hereby assume any fiduciary duties to any of the Lenders, (b) is a “representative” of the Lenders within the meaning of Section 9-105 of the Uniform Commercial Code and (c) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Facility Documents. Each of the Lenders hereby agrees to assert no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives.

11.2 Powers. The Agent shall have and may exercise such powers under the Facility Documents as are specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties to the Lenders, or any obligation to the Lenders to take any action thereunder except any action specifically provided by the Facility Documents to be taken by the Agent.

11.3 General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action taken or omitted to be taken by it or them hereunder or under any other Facility Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person.

11.4 No Responsibility for Revolving Credit Loans, Recitals, etc. Neither the Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify: (a) any statement, warranty or representation made in connection with any Facility Document or any borrowing hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Facility Document, including, without limitation, any agreement by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition specified in Article V, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability,

effectiveness, sufficiency or genuineness of any Facility Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Borrower or any guarantor of any of the Obligations or of any of the Borrower’s or any such guarantor’s respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders information that is not required to be furnished by the Borrower to the Agent at such time, but is voluntarily furnished by the Borrower to the Agent (either in its capacity as Agent or in its individual capacity).

11.5 Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Facility Document in accordance with written instructions signed by the Required Lenders, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Facility Document unless it shall be requested in writing to do so by the Required Lenders. The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Facility Document unless it shall first be indemnified to its satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

11.6 Employment of Agent and Counsel. The Agent may execute any of its duties as Agent hereunder and under any other Facility Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Agent and the Lenders and all matters pertaining to the Agent’s duties hereunder and under any other Facility Document.

11.7 Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Revolving Credit Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may be employees of the Agent.

11.8 Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent ratably in proportion to their respective Revolving Credit Commitments and Letter of Credit Participation Amount (or, if the Aggregate Revolving Credit Commitments and Letter of Credit Commitments have been terminated, in proportion to their Revolving Credit Commitments and Letter of Credit Participation Amount immediately prior to such termination) (a) for any amounts not reimbursed by the Borrower for which the Agent is entitled to reimbursement by the Borrower under the Facility Documents, (b) for any other expenses incurred by the Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the

Facility Documents (including, without limitation, for any expenses incurred by the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders) and (c) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of the Facility Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Facility Documents or of any such other documents; provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Agent and (ii) any indemnification required pursuant to Section 4.5(g) shall, notwithstanding the provisions of this Section 11.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 11.8 shall survive payment of the Obligations and termination of this Agreement.

11.9 Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a “notice of default”. In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders.

11.10 Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the same rights and powers hereunder and under any other Facility Document with respect to its Revolving Credit Commitment, its Revolving Credit Loans, Letter of Credit Participation Amount, and any Letters of Credit in which it has an interest as any Lender and may exercise the same as though it were not the Agent, and the term “Lender” or “Lenders” shall, at any time when the Agent is a Lender, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Facility Document, with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Lender.

11.11 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, the Arranger or any other Lender and based on the financial statements prepared by the Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Facility Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, the Arranger or any other Lender and based on such documents and information as it shall deem appropriate at the time,

continue to make its own credit decisions in taking or not taking action under this Agreement and the other Facility Documents.

11.12 Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its intention to resign. The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders within thirty days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent. Upon the effectiveness of the resignation or removal of the Agent, the resigning or removed Agent shall be discharged from its duties and obligations hereunder and under the Facility Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of this Article XI shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Facility Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 11.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

11.13 Agents’ Fees. The Borrower agrees to pay to the Agent, for its own account, the fees agreed to by the Borrower and the Agent pursuant to the Fee Letter.

11.14 Delegation to Affiliates. The Borrower and the Lenders agree that the Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Articles X and XI.

11.15 Syndication Agent. The Syndication Agent, Senior Managing Agent, Managing Agent, Documentation Agent and Co-Agent shall have no right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, the Syndication Agent, Senior Managing Agent, Managing Agent, Documentation Agent and Co-Agent shall not have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same acknowledgements with respect to the Syndication Agent, Senior Managing Agent, Managing Agent and Co-Agent as it makes to the Agent in Section 11.10.

ARTICLE XII

SETOFF; RATABLE PAYMENTS

12.1 Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Borrower becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender to or for the credit or account of the Borrower may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part hereof, shall then be due.

12.2 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Revolving Credit Loans or Reimbursement Obligations (other than payments received pursuant to Section 4.1, 4.2, 4.4 or 4.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Revolving Credit Loans or participation interests in Letters of Credit, as the case may be, held by the other Lenders so that after such purchase each Lender will hold its ratable proportion of such Revolving Credit Loans or participation interests in Letters of Credit. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their Revolving Credit Loans and Letter of Credit Participation Amounts. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XIII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

13.1 Successors and Assigns. The terms and provisions of the Facility Documents shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns, except that (a) the Borrower shall not have the right to assign its rights or obligations under the Facility Documents and (b) any assignment by any Lender must be made in compliance with Section 13.3. Notwithstanding clause (b) of

the foregoing sentence, any Lender may at any time, without the consent of the Borrower or the Agent, assign all or any portion of its rights under this Agreement and any Revolving Credit Note to a Federal Reserve Bank; provided, however, that no such assignment to a Federal Reserve Bank shall release the transferor Lender from its obligations hereunder. The Agent may treat the Person which made any Revolving Credit Loan, participated in any Letter of Credit or holds any Revolving Credit Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 13.3 in the case of an assignment thereof or, in the case of any other transfer, a written notice of the transfer is filed with the Agent. Any assignee or transferee of the rights to any Revolving Credit Loan, Letter of Credit or Revolving Credit Note agrees by acceptance of such transfer or assignment to be bound by all the terms and provisions of the Facility Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Revolving Credit Loan (whether or not a Revolving Credit Note has been issued in evidence thereof) or any Letter of Credit, shall be conclusive and binding on any subsequent holder, transferee or assignee of the rights to such Revolving Credit Loan or Letter of Credit, as the case may be.

13.2 Participations.

13.2.1 Permitted Participants; Effect. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities (“Participants”) participating interests in any Revolving Credit Loan owing to such Lender, any Revolving Credit Note held by such Lender, any Revolving Credit Commitment of such Lender, any Letter of Credit Participation Amount of such Lender, any interest of such Lender in any Letters of Credit or any other interest of such Lender under the Facility Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Facility Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Revolving Credit Loans and its interest in any Letters of Credit and the holder of any Revolving Credit Note issued to it in evidence thereof for all purposes under the Facility Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Facility Documents.

13.2.2 Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Facility Documents, except to the extent such amendment, modification or waiver would require the unanimous consent of the Lenders as described in Section 9.2.

13.2.3 Benefit of Setoff. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 12.1 in respect of its participating interest in amounts owing under the Facility Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Facility Documents, provided that each Lender shall retain the right of setoff provided in Section 12.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 12.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 12.2 as if each Participant were a Lender.

13.3 Assignments.

13.3.1 Permitted Assignments. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the Facility Documents. Such assignment shall be substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto. The consent of the Borrower and the Agent shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender or an Affiliate thereof; provided, however, that if a Default has occurred and is continuing, the consent of the Borrower shall not be required. Such consent shall not be unreasonably withheld or delayed. Each such assignment shall (unless it is to a Lender or an Affiliate thereof or the Agent otherwise consents) be in an amount not less than the lesser of (a) $5,000,000 or (b) the remaining amount of the assigning Lender’s Revolving Credit Commitment and/or Letter of Credit Participation Amount (calculated as at the date of such assignment).

13.3.2 Effect; Effective Date. Upon (a) delivery to the Agent and the Borrower of a notice of assignment, substantially in the form attached as Exhibit I to Exhibit C (a “Notice of Assignment”), together with any consents required by Section 13.3.1, and (b) payment of a $3,500 fee to the Agent by the assigning Lender or the Purchaser for processing such assignment, such assignment shall become effective on the effective date specified in such Notice of Assignment. The Notice of Assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Revolving Credit Commitment, Revolving Credit Loans and participation interests in the Letters of Credit under the applicable assignment agreement are “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Facility Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Facility Document executed by or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Facility Documents, to the same extent as if it were an original

party hereto, and no further consent or action by the Borrower, the Lenders or the Agent shall be required to release the transferor Lender with respect to the percentage of the Aggregate Revolving Credit Commitment, the Letter of Credit Commitment, Revolving Credit Loans and the participation interests in Letters of Credit assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 13.3.2, the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Revolving Credit Loans be evidenced by Revolving Credit Notes, make appropriate arrangements so that new Revolving Credit Notes or, as appropriate, replacement Revolving Credit Notes are issued to such transferor Lender and new Revolving Credit Notes or, as appropriate, replacement Revolving Credit Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Revolving Credit Commitments, as adjusted pursuant to such assignment.

13.4 Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Facility Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Borrower and its Subsidiaries; provided that each Transferee and prospective Transferee agrees to be bound by Section 10.11 of this Agreement.

13.5 Tax Treatment. If any interest in any Facility Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 4.5(d).

ARTICLE XIV

NOTICES

14.1 Notices. Except as otherwise permitted by Section 2.12 with respect to borrowing notices, all notices, requests and other communications to any party hereunder shall be in writing (including electronic transmission, facsimile transmission or similar writing) and shall be given to such party: (a) in the case of the Borrower or the Agent, at its address or facsimile number set forth on the signature pages hereof, (b) in the case of any Lender, at its address or facsimile number set forth below its signature hereto or (c) in the case of any party, at such other address or facsimile number as such party may hereafter specify for the purpose by notice to the Agent and the Borrower in accordance with the provisions of this Section 14.1. Each such notice, request or other communication shall be effective (i) if given by facsimile transmission, when transmitted to the facsimile number specified in this Section and confirmation of receipt is received, (ii) if given by mail, 72 hours after such communication is deposited in the mails with first class postage prepaid, addressed as aforesaid, or (iii) if given by any other means, when delivered (or, in the case of

electronic transmission, received) at the address specified in this Section; provided that notices to the Agent under Articles II and III shall not be effective until received.

14.2 Change of Address. The Borrower, the Agent and any Lender may each change the address for service of notice upon it by a notice in writing to the other parties hereto.

ARTICLE XV

COUNTERPARTS

This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart. This Agreement shall be effective when it has been executed by the Borrower, the Agent and the Lenders and each party has notified the Agent by facsimile transmission or telephone that it has taken such action.

ARTICLE XVI

CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL

16.1 CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (INCLUDING, WITHOUT LIMITATION, 735 ILCS SECTION 105/5-1 ET SEQ., BUT OTHERWISE WITHOUT REGARD TO THE CONFLICTS OF LAWS PROVISIONS) OF THE STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

16.2 CONSENT TO JURISDICTION. THE BORROWER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR ILLINOIS STATE COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY FACILITY DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY LENDER OR ANY AFFILIATE OF THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY

ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY FACILITY DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN CHICAGO, ILLINOIS.

16.3 WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY FACILITY DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.
