ARTICLE II

THE LETTER OF CREDIT FACILITY

2.1 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 Letter 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) $10,000,000; 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 faith deems material to it, (ii) one or more of the conditions to such issuance contained in Section 4.2 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. For purposes of clause (iii) of the immediately preceding sentence, at any time there is a Defaulting Lender, the Letter of Credit Commitment shall be automatically reduced by an amount equal to the remainder of (A) such Defaulting Lender’s pro-rata share of the Letter of Credit Commitment minus (B) such Defaulting Lender’s pro-rata share of the Letter of Credit Obligations then outstanding; provided, however, the Letter of Credit Commitment shall be restored if either (i) such Defaulting Lender provides cash collateral to the Agent for the account of such Defaulting Lender pursuant to Section 10.11 in the amount of such Defaulting Lender’s pro-rata share of the Letter of Credit Commitment or (ii) the Borrower has entered into satisfactory arrangements with the Issuer to eliminate the Issuer’s risk with respect to such Defaulting Lender, it being agreed that such satisfactory arrangements may include collateral or the charging of a fee and the Lenders agree that any such collateral or fee shall belong solely to the Issuer and shall not be subject to the sharing provisions of this Agreement. Letters of Credit shall be denominated, at the Borrower’s option, in either Dollars or Pounds.

(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 2.1 hereto) or the date for payment of any draft presented thereunder and accepted by the Issuer, be later than (x) the date one (1) year after the effective date of such Letter of Credit or (y) in the case of the Lloyd’s Letters of Credit, four (4) years after the date of the related Expiry Notice. The Issuer shall not permit the renewal or extension of any Letter of Credit at any time (A) during the continuation of a Default or Unmatured Default or (B) after the Letter of Credit Availability Termination Date.

(c) The Issuer (i) shall issue an Expiry Notice on the Letter of Credit Availability Termination Date and (ii) may, and upon the request of the Required Lenders

shall, issue an Expiry Notice when a Default has occurred and is continuing; provided, however, that upon the occurrence of an Unmatured Default pursuant to Sections 7.6 and 7.7, the Issuer shall immediately issue an Expiry Notice.

(d) The Borrower agrees that, if at any time as a result of reductions in the Letter of Credit Commitment pursuant to Section 2.3 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 a Collateral Account, Cash Collateral Investments with a Collateral Value equal to the product of one hundred and three percent (103%) of the amount as may be necessary to eliminate such excess.

(e) The Letters of Credit identified on Schedule 2.1 hereto (the “Existing Letters of Credit”) which are issued and outstanding under the Existing Credit Agreement shall, upon satisfaction of the conditions set forth in Article IV 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.

(f) For purposes of determining usage and availability under this Section 2.1, 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 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 a Collateral Account Cash Collateral Investments with a Collateral Value equal to the product of one hundred and three percent (103%) of the Conversion Differential.

(g) At the request of the Borrower, Letters of Credit may be issued with any Wholly-Owned Subsidiary of the Borrower as a co-applicant, so long as the Borrower is also a co-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 a co-applicant shall include language substantially similar to that set forth in Exhibit C or otherwise acceptable to the Agent.

2.2 Participating Interests. Immediately upon the issuance by the Issuer of a Letter of Credit in accordance with Section 2.5 (and with respect to the Letters of Credit identified on Schedule 2.1 hereto, upon satisfaction of the conditions set forth in Article IV 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 (including as may be adjusted pursuant to Section 2.1(a)) of the face amount of such Letter of Credit and each draw paid by the Issuer thereunder; provided, however, that during any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit pursuant to this Section 2.2, the pro-rata share of each non-Defaulting Lender shall be computed without including such Defaulting Lender’s share of the Letter of Credit Commitment; provided, further, that once such Defaulting Lender shall cease to be a Defaulting Lender or has provided cash collateral to the Agent pursuant to Section 10.11, the pro-rata share of each Lender shall be recalculated including all Lenders’ share of the Letter of Credit Commitment. Notwithstanding the foregoing, under no circumstances shall any Lender be deemed to have purchased a participation interest in excess of such Lender’s commitment amount. 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.

2.3 Reductions in Letter of Credit Commitment. (a) The Borrower may permanently reduce the Letter of 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 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.

(b) At any time a Lender is a Designated Lender, the Borrower may terminate in full the commitment of such Designated Lender by giving notice to such Designated Lender and the Agent; provided that (i) at the time of such termination, no Default or Unmatured Default exists (or the Required Lenders consent to such termination) and (ii) concurrently with such termination, (A) the Letter of Credit Commitment shall be reduced by the commitment amount of such Designated Lender (it being understood that the Borrower may not terminate the commitment of a Designated Lender if, after giving effect to such termination, the Letter of Credit Obligations would exceed the reduced Letter of Credit Commitment), (B) the Borrower shall pay all amounts owed to such Designated Lender hereunder and (C) the Agent shall return to such Lender any cash collateral held for the account of such Lender pursuant to Section 2.9(d). The termination of the commitment of a Defaulting Lender pursuant to this Section 2.3 shall not be deemed to be a waiver of any right that (x) the Borrower, the Agent, the Issuer or any other Lender may have against such Defaulting Lender or (y) such Defaulting Lender may have against the Borrower based on the estimate described in clause (B) of the preceding sentence.

2.4 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. (New York 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 2.9 or in the applicable Reimbursement Agreement and (ii) interest on any and all amounts remaining unpaid under this Section 2.4 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 plus the Applicable Margin for such day for the first two days following the due date of any Reimbursement Obligations and (B) the Alternate Base Rate plus the Applicable Margin for such day plus 2% per annum thereafter. 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.

(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 Letter of 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 (New York 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 2.4(c)), 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.

2.5 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.

2.6 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.

(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.

2.7 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.

2.8 Cash Collateral for Letters of Credit. On the Letter of Credit Availability Termination Date, the Borrower shall pledge and deliver to the Agent, for the benefit of the Secured Parties, Cash Collateral Investments in a Collateral Account with a Collateral Value equal to the product of one hundred and three percent (103%) of the amount equal to the following percentage of the Letter of Credit Obligations outstanding from time to time during the following periods:

		Percentage of Letter of Credit
Period		Obligations Collateralized
Letter of Credit Availability Termination Date to but not including the date nine (9) months after the Letter of Credit Availability Termination Date			50	%
the date nine (9) months after the Letter of Credit Availability Termination Date, or an earlier date at the Borrower’s option, and at all times thereafter			100	%

2.9 Fees.

(a) Unused Fee. The Borrower agrees to pay to the Agent for the account of each Lender with respect to its Letter of Credit Participation Amount an unused fee at a rate per annum equal to the Applicable Unused 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, calculated with respect to actual days elapsed on the basis of a 360-day year and payable on each Payment Date hereafter and on the Letter of Credit Availability Termination Date or, if later, upon receipt of a bill from the Agent. Accrued and unpaid unused fees under the Existing Credit Agreement shall be paid on the Closing Date or, if later, upon receipt of a bill 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 2.1, the date on which such Letters of Credit are deemed issued under this Agreement pursuant to Section 2.1(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 bill 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 7.6 or 7.7, the Applicable Letter of Credit Participation Fee Rate shall be increased by two percent (2%) without any election or action on the part of the Agent or any Lender. Accrued and unpaid Letter of Credit Participation Fees under the Existing Credit Agreement shall be paid on the Closing Date or, if later, upon receipt of a bill from the Agent.

(d) If at any time a Lender is a Defaulting Lender, then, to the extent permitted by applicable law (and notwithstanding any other provision of this Agreement), (i) any payment of Reimbursement Obligations with respect to Letters of Credit (including through sharing of payments pursuant to Section 10.2, but excluding any payment pursuant to Section 2.3(b) shall, if the Borrower so directs at the time of making such payment, be applied first to amounts owed to Lenders other than such Defaulting Lender, as if the amount owed to such Defaulting Lender hereunder in respect of Reimbursement Obligations were zero, and then to amounts owed to such Defaulting Lender; (ii) such Defaulting Lender’s pro-rata share of the Letter of Credit Obligations shall be excluded for purposes of calculating facility fees pursuant to Section 2.9 in respect of each day on which such Lender is a Defaulting Lender, and such Defaulting Lender shall not be entitled to receive any facility fees for any such day and (iii) such Defaulting Lender’s pro-rata share shall be deemed to be zero for purposes of calculating letter of credit fees pursuant to Section 2.9 in respect of each day on which such Lender is a Defaulting Lender (and the pro-rata shares of the other Lenders shall be correspondingly increased for such purposes), and such Defaulting Lender shall not be entitled to receive any letter of credit fees for any such day. In addition, if any Lender is a Defaulting Lender at the time any payment is to be made by the Lenders to the Issuer pursuant to Section 2.4(c) and such Defaulting Lender fails to make its pro-rata share of such payment, then, solely for purposes of determining the amount of the payment to be made by each Lender to the Issuer (and without limiting the liability of such Defaulting Lender for its failure to make such payment), the pro-rata shares of the other Lenders

shall be correspondingly increased so that, subject to the following proviso, the Issuer receives the full amount of the payments to which it is entitled from the Lenders; provided that under no circumstances shall any Lender be obligated to make a payment to the Issuer pursuant to this sentence that would cause the aggregate principal amount of such Lender’s pro-rata share (without giving effect to any adjustment pursuant to the foregoing provisions of this sentence) of all Letter of Credit Obligations to exceed such Lender’s commitment amount (or, if the Letter of Credit Commitment has terminated, such Lender’s commitment amount at the time of such termination, adjusted for any assignments by or to such Lender). Any payment made pursuant to this Section shall be taken into account for purposes of calculating the Unused Fee and Letter of Credit Participation Fee. The provisions of this Section 2.9(d) do not limit, but are in addition to, any other claim or right that the Borrower, the Agent, the Issuer or any other Lender may have against a Defaulting Lender.

2.10 Extension of Letter of Credit Availability Termination Date. The Borrower may request an extension of the Letter of Credit Availability 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. The Extension Request must specify the new Letter of Credit Availability 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 shall not be more than two years after the Letter of Credit Availability Termination Date in effect at the time the Extension Request is received, including the Letter of Credit Availability 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 specified in the Extension Request shall become effective on the existing Letter of Credit Availability 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. Otherwise the Letter of Credit Availability Termination Date shall be unchanged.

2.11 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 D, request that the Letter of Credit Commitment be increased by an aggregate amount (for all such increases) not exceeding $25,000,000 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 V 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 2.11 shall be effective three (3) 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 D (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 D (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 2.11 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 2.11 is not expressly authorized pursuant to resolutions or consents delivered pursuant to Section 4.1(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.

2.12 Collateral Account.

(a) The Borrower shall at all times maintain Cash Collateral Investments in Collateral Accounts with a Collateral Value of not less than the Required Amount. If at any time the Required Amount shall exceed (the amount of such excess, the “Collateral Shortfall”) the Collateral Value for three (3) consecutive Business Days, the Agent shall provide the Borrower notice, by telephone or in writing, of such Collateral Shortfall and it shall be a Default unless within three (3) Business Days of the Borrower’s receipt of such notice, no Collateral Shortfall exists as a result of (i) a change in the Collateral Value due to market fluctuations and/or (ii) a deposit by the Borrower of additional Cash Collateral Investments in a Collateral Account.

(b) Cash Collateral Investments held in a Collateral Account shall be invested (i) so long as no Default has occurred, at the direction of the Borrower, provided that all such Cash Collateral Investments must be reasonably acceptable to the Agent and otherwise permitted by this Agreement, and (ii) following the occurrence and continuation of a Default, at the direction of the Agent. All income from such Cash Collateral Investments shall be retained in a Collateral Account and added to the Collateral.

(c) So long as no Default has occurred and is continuing, if at any time the Obligations become due and payable hereunder, the Borrower may direct the application of all or any part of the Cash Collateral Investments held in a Collateral Account for the amount which is due and payable, including with respect to any Reimbursement

Obligations; provided, however, the Agent shall have the right, upon five (5) days’ prior notice to the Borrower, to apply all or any part of the Cash Collateral Investments held in a Collateral Account for the amount which is due and payable unless the Borrower shall object in writing and otherwise pay the amount due and payable within such five (5) day period. Upon the occurrence and continuation of a Default, the Agent may apply (without prior notice to the Borrower) all or any part of the Cash Collateral Investments held in a Collateral Account pursuant to and in accordance with Section 8.4.

(d) So long as no Default or Unmatured Default under Section 7.2 has occurred, at any time the Collateral Value exceeds (the amount of such excess, the “Collateral Excess”) the Required Amount, the Borrower can request to receive or otherwise direct the application of such Collateral Excess and the Agent shall release any Lien it has with respect to such Collateral Excess; provided, however, upon the occurrence and continuation of a Default, the Agent shall have sole control over any such Collateral Excess, including the application of such amount pursuant to and in accordance with Section 8.4.

ARTICLE III

YIELD PROTECTION; TAXES

3.1 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:

(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 interest in the Letters of Credit,

(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 issuing Letters of Credit or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with any Letter of Credit, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the

amount of Letters of Credit issued or participated in or interest received by it, by an amount deemed material by such Lender,

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 Letter of 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 Letter of Credit Commitment or interest in Letters of Credit, then, within fifteen (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.

3.2 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 fifteen (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, 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 November 2005 updated report of the Basel Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards: A Revised Framework,” including transition rules, and any amendments to such regulations adopted prior to the Closing Date.

3.3 Taxes. (a) All payments by the Borrower to or for the account of any Lender or the Agent hereunder or under any Reimbursement Agreement 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 3.3) 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.

(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 other Facility Document or from the execution or delivery of, or otherwise with respect to, this Agreement or any other Facility Document (“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 3.3) 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 3.4.

(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, 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 3.3 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 other Facility Document 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 3.3(g) shall survive the payment of the Obligations and termination of this Agreement.

3.4 Lender Statements; Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.3 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 3.1, 3.2 or 3.3. 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. The obligations of the Borrower under Section 3.1, 3.2 and 3.3 shall survive payment of the Obligations and termination of this Agreement.

REPRESENTATIONS AND WARRANTIES

The Borrower represents and warrants to the Lenders that:

5.1 Existence and Standing. Each of the Borrower and its Subsidiaries is duly and properly formed, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization and, except as could not reasonably be expected to have a Material Adverse Effect, has all requisite authority to conduct its business in each jurisdiction in which its business is conducted.

5.2 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.

5.3 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 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.

5.4 Financial Statements. (a) The consolidated balance sheets of the Borrower and the Consolidated Subsidiaries as of December 31, 2009, 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 LLP, 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 Consolidated Subsidiaries for the periods covered by such statements, all in accordance with Agreement Accounting Principles consistently applied.

(b) There are no liabilities of the Borrower or any of the Consolidated Subsidiaries, fixed or contingent, which are material but are not reflected in the most recent financial statements referred to above or in the notes thereto, other than liabilities arising in the ordinary course of business since December 31, 2009.

5.5 Statutory Financial Statements. The Annual Statement of each of the Insurance Subsidiaries (including, without limitation, the provisions made therein for investments and the valuation thereof, reserves, policy and contract claims and statutory liabilities) as filed with the appropriate Governmental Authority of its state of domicile (the “Department”) and delivered to each Lender prior to the execution and delivery of this Agreement, as of and for the 2009 Fiscal Year (the “Statutory Financial Statements”), have been prepared in accordance with SAP applied on a consistent basis (except as noted therein). Each such Statutory Financial Statement was in material compliance with applicable law when filed.

5.6 Material Adverse Change. Since December 31, 2009 there has been no change in the business, Property, condition (financial or otherwise) or results of operations of

the Borrower and its Subsidiaries which could reasonably be expected to have a Material Adverse Effect.

5.7 Taxes. The Borrower and its Subsidiaries have filed all United States federal tax returns and all other tax returns which are required to be filed and have paid all taxes due pursuant to said returns or pursuant to any assessment received by the Borrower or any of its Subsidiaries, except such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided in accordance with Agreement Accounting Principles and as to which no Lien exists. No tax liens have been filed and no claims are being asserted with respect to any such taxes. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of any taxes or other governmental charges are adequate.

5.8 Litigation and Contingent Obligations. There is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of their officers, threatened against or affecting the Borrower or any of its Subsidiaries which could reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the issuance of any Letters of Credit. Other than any liability incident to any litigation, arbitration or proceeding which could not reasonably be expected to have a Material Adverse Effect, the Borrower has no material contingent obligations not provided for or disclosed in the financial statements referred to in Section 5.4.

5.13 Regulation U. Margin stock (as defined in Regulation U) constitutes less than 25% of the value of those assets of the Borrower and its Subsidiaries which are subject to any limitation on sale, pledge, or other restriction hereunder. Neither the issuance of any Letters of Credit hereunder nor the use of the proceeds thereof, will violate or be inconsistent with the provisions of Regulation T, Regulation U or Regulation X.

5.15 Compliance With Laws. The Borrower and its Subsidiaries have complied with all applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign government or any instrumentality or agency thereof having jurisdiction over the conduct of their respective businesses or the ownership of their respective Property, except where the failure to comply could not reasonably be expected to have a Material Adverse Effect.

The Borrower and each of its Subsidiaries has good title, free of all Liens other than those permitted by Section 6.16, to all of the Property and assets reflected in the Borrower’s most recent consolidated financial statements filed with the Securities and Exchange Commission as owned by the Borrower and its Subsidiaries.

5.18 Environmental Matters. In the ordinary course of its business, the officers of the Borrower consider the effect of Environmental Laws on the business of the Borrower and its Subsidiaries, in the course of which they identify and evaluate potential risks and liabilities accruing to the Borrower due to Environmental Laws. On the basis of this consideration, the Borrower has concluded that Environmental Laws cannot reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any Subsidiary has received any notice to the effect that its operations are not in material compliance with any of the requirements of applicable Environmental Laws or are the subject of any federal or state

investigation evaluating whether any remedial action is needed to respond to a release of any toxic or hazardous waste or substance into the environment, which non-compliance or remedial action could reasonably be expected to have a Material Adverse Effect.

Immediately after the consummation of the transactions to occur on the date hereof and immediately following each issuance of a Letter of Credit (including the Existing Letters of Credit) hereunder on the date hereof and after giving effect to the application of the proceeds of such Letters of Credit, (a) the fair value of the assets of the Borrower and its Subsidiaries on a consolidated basis, at a fair valuation, will exceed the debts and liabilities, subordinated, contingent or otherwise, of the Borrower and its Subsidiaries on a consolidated basis, (b) the present fair saleable value of the Property of the Borrower and its Subsidiaries on a consolidated basis will be greater than the amount that will be required to pay the probable liability of the Borrower and its Subsidiaries on a consolidated basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured, (c) the Borrower and its Subsidiaries on a consolidated basis will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured and (d) the Borrower and its Subsidiaries on a consolidated basis will not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted after the date hereof.

5.21 Insurance Licenses. To the extent required by applicable law, each Insurance Subsidiary holds a License and is authorized to transact insurance business in (i) the line or lines of insurance and (ii) the state, states or jurisdictions it is engaged in, except to the extent that the failure to have such a License or authority could not reasonably be expected to have a Material Adverse Effect. No such License, the loss of which could reasonably be expected to have a Material Adverse Effect, is the subject of a proceeding for suspension, limitation or revocation. To the Borrower’s knowledge, there is not a sustainable basis for such suspension, limitation or revocation, and no such suspension, limitation or revocation has been threatened by any Governmental Authority. The Insurance Subsidiaries do not transact any business, directly or indirectly, requiring any license, permit, governmental approval, consent or other authorization other than those currently obtained, except to the extent of which could not reasonably be expected to have a Material Adverse Effect.

None of the (a) information, exhibits or reports furnished or to be furnished by the Borrower or any Subsidiary to the Agent or to any Lender in connection with the negotiation of the Facility Documents or (b) representations or warranties of the Borrower or any Subsidiary contained in this Agreement, the other Facility Documents or any other document, certificate or written statement furnished to the Agent or the Lenders by or on behalf of the Borrower or any Subsidiary for use in connection with the transactions contemplated by this Agreement or the Facility Documents contained, contains or will contain any untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements contained herein or therein not misleading in light of the circumstances in which the same were made. There is no fact known to the Borrower (other than matters of a general economic nature) that has had or could reasonably be expected to have a Material Adverse Effect and that has not been disclosed herein or in such other documents, certificates and statements furnished to the Lenders for use in connection with the transactions contemplated by this Agreement.

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

8.1 Acceleration. If any Default described in Section 7.6 or 7.7 occurs with respect to the Borrower, the obligations of the Issuer and the Lenders to issue Letters of Credit hereunder shall automatically terminate and the Obligations shall immediately become due and payable without any election or action on the part of the Agent or any Lender. If any other Default occurs, the Required Lenders (or the Agent with the consent of the Required Lenders) may terminate or suspend the obligations of the Issuer and the Lenders to issue Letters of Credit hereunder, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which the Borrower hereby expressly waives. In addition to the foregoing, following the occurrence and during the continuance of a Default, so long as any Letter of Credit has not been fully drawn and has not been canceled or expired by its terms, upon demand by the Agent (which demand shall be made upon the request of the Required Lenders), the Borrower shall deposit, in a Collateral Account, Cash Collateral Investments with a Collateral Value equal to the product of one hundred and three percent (103%) of the aggregate undrawn face amount of all outstanding Letters of Credit and all fees and other amounts due or which may become due with respect thereto.

If, within thirty (30) days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to issue Letters of Credit hereunder as a result of any Default (other than any Default as described in Section 7.6 or 7.7 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) may direct the Agent to rescind and annul such acceleration and/or termination.

8.2 Amendments. Subject to the provisions of this Article VIII, the Required Lenders (or the Agent with the consent of the Required Lenders) and the Borrower may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the Facility Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving any Default hereunder; provided, however, that no such supplemental agreement shall, without the consent of each Lender:

(a) Extend the final maturity of any Obligations or forgive all or any portion of the Reimbursement Obligations, or reduce the rate or extend the time of payment of interest or fees (including without limitation letter of credit fees) hereunder;

(b) Reduce the percentage specified in the definition of Required Lenders;

(c) Reduce the amount of or extend the date for payment of Reimbursement Obligations or commitment and facility reductions required under Section 2.4 or 2.10, or increase the amount of the Letter of Credit Participation Amount of any Lender hereunder;

(d) Extend the Letter of Credit Availability Termination Date; permit any Letter of Credit to have an expiry date beyond four years after notice, in the case of Lloyd’s Letters of Credit, or one year after its effective date in the case of other Letters of Credit; except as permitted in Section 2.5, permit the amendment or extension of any Letter of Credit; or, except as otherwise set forth in Section 2.1(b), permit the renewal of any Letter of Credit;

(e) Permit any amendment of Sections 2.4(d) or 8.4;

(f) Release any guarantor of any Obligations or, except as provided in the Pledge Agreement, release any of the collateral for the Obligations or decrease the amount of collateral required under Sections 2.1(d), 2.1(f), 2.8, 2.12(a) or 8.1;

(g) Permit any assignment by the Borrower of its Obligations or its rights hereunder; or

(h) Permit any amendment of the Reinsurance Guidelines;

provided, further, that no such supplemental agreement shall, without the consent of each Lender, amend this Section 8.2. 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 12.3(b) without obtaining the consent of any other party to this Agreement. Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or

consent hereunder, except that the commitment of such Lender may not be increased or extended without the consent of such Lender.

8.3 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 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 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 8.2, 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.

8.4 Application of Funds. After the occurrence of a Default, any amounts received on account of the Obligations (including proceeds of Collateral) shall be applied by the Agent in the following order:

First, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts (including fees, charges and disbursements of counsel to the Agent and amounts payable under Article III) payable to the Agent in its capacity as such;

Second, to payment of that portion of the Obligations constituting fees, indemnities and other amounts (other than Reimbursement Obligations, interest and Letter of Credit fees) payable to the Lenders and the Issuer (including fees, charges and disbursements of counsel to the respective Lenders and the Issuer (including, without duplication, fees and time charges for attorneys who may be employees of any Lender or the Issuer) and amounts payable under Article III), ratably among them in proportion to the respective amounts described in this clause Second payable to them;

Third, to payment of that portion of the Obligations constituting accrued and unpaid Letter of Credit fees and interest on the Reimbursement Obligations and other Obligations, ratably among the Lenders and the Issuer in proportion to the respective amounts described in this clause Third payable to them;

Fourth, to payment of that portion of the Obligations constituting unpaid Reimbursement Obligations, ratably among the Lenders and the Issuer in proportion to the respective amounts described in this clause Fourth held by them;

Fifth, to the Agent for the account of the Issuer to be held as Collateral for that portion of Letter of Credit Obligations comprised of the aggregate undrawn amount of Letters of Credit; and

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in full and the Letter of Credit Commitment has been terminated, to the Borrower or as otherwise required by Law.

Amounts held as Collateral for the aggregate undrawn amount of Letters of Credit pursuant to clause Fifth above shall be applied to satisfy drawings under such Letters of Credit as they occur. If any Collateral remains after all Letters of Credit have either been fully drawn or expired, such remaining amount shall be applied to the other Obligations, if any, in the order set forth above.

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 sue 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.

9.11 Confidentiality.

10.1 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 X.

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.

10.3 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.

10.5 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.

10.6 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.

10.8 Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent ratably in proportion to their Letter of Credit Participation Amount (or, if the Letter of Credit Commitments has been terminated, in proportion to its 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 3.5(g) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

10.9 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.

10.10 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 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.

10.11 Rights with Respect to Designated Lenders. If any Lender is a Designated Lender, then the Issuer may, by notice to such Designated Lender and the Agent, require such Designated Lender to (a) deliver to the Agent, for the account of the Issuer, cash collateral in an amount equal to the product of one hundred and three percent (103%) of the remainder of (i) such Designated Lender’s pro-rata share of the Letter of Credit Commitment minus (ii) the principal amount of such Designated Lender’s pro-rata share of the Letter of Credit Obligations then outstanding (the “Reserve Amount”) or (b) and solely with respect to a Designated Lender that is not a Defaulting Lender, make other arrangements reasonably

satisfactory to the Issuer to assure that such Designated Lender will reimburse the Issuer for its pro-rata share of any payment made by the Issuer under any Letter of Credit. Any such cash collateral (i) shall be held by the Agent pursuant to arrangements reasonably satisfactory to such Designated Lender, the Issuer and the Agent and (ii) if at any time such Designated Lender becomes obligated to pay any amount to the Issuer pursuant to Section 2.4, shall be applied (to the extent required) by the Agent to pay such amount. Upon the expiration, termination or reduction in amount of any applicable Letter of Credit, the Agent shall release (subject to Section 2.9(d) in the case of a Defaulting Lender) to such Designated Lender (or such other Person as may be entitled thereto) any cash collateral held by the Agent in excess of the Reserve Amount. If any Designated Lender fails to provide cash collateral or make other arrangements as required by the first sentence of this Section 10.11, then the Agent shall retain as cash collateral all amounts otherwise payable to such Designated Lender under this Agreement until the Agent has retained an amount equal to the Reserve Amount.

10.12 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.

10.13 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 X 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 10.13, 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.

10.14 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.

10.15 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 IX and X.

10.16 Joint Lead Arranger; Syndication Agent; Documentation Agent. The Joint Lead Arrangers (other than the Arranger), the Syndication Agent and the Documentation 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 Joint Lead Arrangers (other than the Arranger), the Syndication Agent and the Documentation 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 Joint Lead Arrangers (other than the Arranger), the Syndication Agent and the Documentation Agent as it makes to the Agent in Section 10.10.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

11.1 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.

11.2 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Reimbursement Obligations (other than payments received

pursuant to Section 3.1, 3.2 or 3.3) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a 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 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 Letter of Credit Participation Amounts. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1 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 12.3. 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 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 participated in any Letter of Credit as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3 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 Letter of Credit 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 Letter of Credit, shall be conclusive and binding on any subsequent holder, transferee or assignee of the rights to such Letter of Credit, as the case may be.

12.2 Participations.

(a) 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 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 interest in any Letters of Credit 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.

(b) 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 8.2.

(c) Benefit of Setoff. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 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 11.1 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 11.1, 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 11.2 as if each Participant were a Lender.

12.3 Assignments.

(a) 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 B 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; provided, further, that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereto. 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 Letter of Credit Participation Amount (calculated as at the date of such assignment).

(b) 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 B (a “Notice of Assignment”), together with any consents required by Section 12.3(b), 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 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 Letter of Credit Commitment and the participation interests in Letters of Credit assigned to such Purchaser.

12.4 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 9.11 of this Agreement.

12.5 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 3.5(d).

ARTICLE XIII

ARTICLE XV

THE FACILITY DOCUMENTS (OTHER THAN THOSE CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARDS TO THE CONFLICT OF LAW PROVISIONS THEREOF OTHER THAN SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

Applicable Margin			0.50	%			0.75	%			1.00	%			1.50	%

For the purposes of this Schedule, the following terms have the following meanings, subject to the final paragraph of this Schedule:

“Level I Status” exists at any date if, on such date, the Borrower’s S&P Rating is BBB+ or better or the Borrower’s Moody’s Rating is Baa1 or better.

“Level II Status” exists at any date if, on such date, (i) the Borrower has not qualified for Level I Status and (ii) the Borrower’s S&P Rating is BBB or better or the Borrower’s Moody’s Rating is Baa2 or better.

“Level III Status” exists at any date if, on such date, (i) the Borrower has not qualified for Level I Status or Level II Status and (ii) the Borrower’s S&P Rating is BBB- or better or the Borrower’s Moody’s Rating is Baa3 or better.

“Level IV Status” exists at any date if, on such date, the Borrower has not qualified for Level I Status, Level II Status or Level III Status.

“Status” means Level I Status, Level II Status, Level III Status or Level IV Status.

The Applicable Margin and Applicable Fee Rate shall be determined in accordance with the foregoing table based on the Borrower’s Status as determined from its then-current Borrower’s S&P Rating and Borrower’s Moody’s Rating; provided that if the Borrower’s S&P Rating and the Borrower’s Moody’s Rating are not on the same Level, the better Rating shall apply except that if the Ratings differ by more than one Level than the Level above the lower Rating shall apply. The Rating in effect on any date for the purposes of this Schedule is that in effect at the close of business on such date. If at any time the Borrower has only a Borrower’s S&P Rating or a Borrower’s Moody’s Rating, the Borrower’s Status shall be determined from its then current Borrower’s S&P Rating or Borrower’s Moody’s Rating, as the case may be. If at any time the Borrower has neither a Borrower’s S&P Rating nor a Borrower’s Moody’s Rating, Level IV Status shall exist.
