2.01 The Letters of Credit. The Issuing Bank agrees, on the terms and subject to the conditions herein set forth, to issue standby letters of credit, substantially in the form of Exhibit B-1 or Exhibit B-2, or in such other form as the Issuing Bank may approve (such approval not to be unreasonably withheld or delayed so long as such form complies with the following provisions of this Section 2.01) (each an “LOC” and collectively the “LOCs”), and extend or increase the amount of LOCs, for the account of ACE on any Business Day from time to time during the period from the Closing Date to the Termination Date; provided that (a) the Issuing Bank shall not have any obligation to issue, extend or increase the amount of any LOC if (i) the aggregate Credit Exposure (after giving effect to such issuance, extension or increase) would exceed the LOC Availability Amount (as defined in the Pricing Agreement) scheduled to be outstanding at any time during the period from the date of such issuance, extension or increase to the stated expiration date of such LOC; or (ii) such issuance, extension or increase would conflict with or cause the Issuing Bank to exceed any limit imposed by applicable law or any applicable requirement thereof; (b) each LOC shall be denominated in U.S. dollars and shall be in a face amount not less than $50,000 (or such lesser amount as the Issuing Bank may agree); (c) each LOC shall be payable only against sight drafts (and not time drafts); (d) no LOC shall have a scheduled expiration date (including all rights of ACE or the beneficiary to require extension thereof) later than the fifth (5^th) Business Day prior to the date on which the aggregate Credit Exposure (including the subject LOC) would exceed the aggregate LOC Availability Amount scheduled to be outstanding at any time during such period if such subject LOC remained outstanding on such date; (e) the Issuing Bank shall not have any obligation to issue any LOC that the Issuing Bank determines, in the exercise of its reasonable judgment consistent with its customary practice, is unsatisfactory in form or substance or is to be issued in favor of a beneficiary that is a Sanctioned Person, is organized under the laws of a Sanctioned Country or is otherwise unsatisfactory to the Issuing Bank; (f) each LOC issued in the form of Exhibit B-1 shall provide that such LOC shall expire on the thirtieth (30^th) day following written notice by

the Issuing Lender to the beneficiary of the occurrence of a “Credit Event” with respect to ACE consisting of a “Failure to Pay” or a “Bankruptcy” (as each such term is defined in the 2003 ISDA Credit Derivatives Definitions published by the International Swaps and Derivatives Association, Inc.); and (g) prior to issuing any LOC in the form of Exhibit B-2, the Issuing Bank or Administrative Agent shall have entered into a reinsurance trust agreement with a reinsurance trustee, in form and substance satisfactory to the Issuing Bank and Administrative Agent and containing terms substantially similar to those set forth on Exhibit C, and, upon issuance of such LOC, such LOC shall be immediately deposited into the reinsurance trust account governed by the terms of such reinsurance trust agreement, and shall at all times thereafter be held in such reinsurance trust account. An LOC may by its terms be automatically extendible annually; provided, that the Issuing Bank shall not permit any such automatic extension if it has determined that such extension would not be permitted, or the Issuing Bank would have no obligation, at such time to issue such LOC as extended under the terms hereof, in which case the Issuing Bank shall notify the beneficiary thereof of its election not to extend such LOC (which the Issuing Bank agrees to do on and subject to the terms of Section 2.02(c)). LOCs may be issued for the benefit of any wholly-owned Subsidiary of ACE; provided that ACE shall be the account party with respect to any such LOC.

2.02 Issuance and Extensions and Drawings, Participations and Reimbursement with Respect to Letters of Credit.

(a) Request for Issuance. ACE may from time to time request, upon at least three Business Days’ notice (given not later than 11:00 A.M.), that the Issuing Bank issue an LOC by delivering to the Issuing Bank (i) a written request substantially in the form of Exhibit D (an “LOC Application”) specifying the date on which such LOC is to be issued (which shall be a Business Day), the expiration date thereof, the Available Amount thereof and the name and address of the beneficiary thereof; and (ii) such other documents as may be required pursuant to the Issuing Bank’s customary practices for the issuance of letters of credit.

If the requirements set forth in the proviso to the first sentence of Section 2.01 and in Article III are satisfied, the Issuing Bank shall issue the applicable LOC on the date requested in such LOC Application. Upon the issuance of an LOC, the Issuing Bank shall (A) deliver the original of such LOC to the beneficiary thereof or as ACE shall otherwise direct and (B) promptly notify the Administrative Agent thereof and furnish a copy thereof to the Administrative Agent. The Issuing Bank may issue LOCs through any of its branches or Affiliates (whether domestic or foreign) that issue letters of credit.

(b) Request for Extension or Increase. ACE may from time to time request, upon at least three Business Days’ notice (given not later than 11:00 A.M.), that the Issuing Bank extend the expiration date of an outstanding LOC or increase (or, with the consent of the beneficiary, decrease) the Available Amount of an outstanding LOC by delivering to the Issuing Bank a written request therefor. Any such request for an extension or increase shall for all purposes hereof (including for purposes of Section 2.02(a)) be treated as though ACE had requested issuance of a replacement LOC (except that the Issuing Bank may, if it elects, issue a notice of extension or increase in lieu of issuing a new LOC in substitution for the outstanding LOC).

(c) Automatic Extensions. If any LOC shall provide for the automatic extension of the expiry date thereof unless the Issuing Bank gives notice that such expiry date shall not be extended, then the Issuing Bank shall allow such LOC to be extended unless it shall have received, at least five days prior to the date on which such notice of non-extension must be delivered under such LOC (or such shorter period acceptable to the Issuing Bank), (i) notice from the Required Banks (or the Administrative Agent on their behalf) stating that the conditions precedent to the extension of such LOC have not been satisfied or (ii) notice from ACE directing the Issuing Bank not to permit the extension of such LOC (and the Issuing Bank shall not permit any LOC to be automatically extended if it has received a timely notice of the type described in the foregoing clause (i) or (ii)).

(d) Limitations on Issuance, Extension and Increase of LOCs. As between the Issuing Bank, on the one hand, and the Administrative Agent and the other Banks, on the other hand, the Issuing Bank shall be justified and fully protected in issuing a proposed LOC, extending the expiration date or increasing the Available Amount of an outstanding LOC or permitting an outstanding LOC to be automatically extended if the Issuing Bank has not received notice that it is not authorized to issue, increase the Available Amount of or extend such LOC as described in the foregoing provisions of this Section 2.02, in each case notwithstanding any subsequent notice to the Issuing Bank, any knowledge the Issuing Bank may have of a Default or of the failure of any condition specified the proviso to the first sentence of Section 2.01 or in Article III to be satisfied, or any other event, condition or circumstance whatsoever. The Issuing Bank may amend, modify or supplement LOCs or LOC Applications, or waive compliance with any condition of issuance, extension or payment, without the consent of, and without liability to, the Administrative Agent or any Bank, provided that any such amendment, modification or supplement that extends the expiration date or increases the Available Amount of or the amount available to be drawn on an outstanding LOC shall be subject to Section 2.01.

(e) Letter of Credit Participating Interests. Concurrently with the issuance of each LOC, the Issuing Bank automatically shall be deemed, irrevocably and unconditionally, to have sold, assigned, transferred and conveyed to each other Bank, and each other Bank automatically shall be deemed, irrevocably and unconditionally, severally to have purchased, acquired, accepted and assumed from the Issuing Bank, without recourse to, or representation or warranty by, the Issuing Bank, an undivided interest, in a proportion equal to such Bank’s Pro Rata Share, in all of the Issuing Bank’s rights and obligations in, to or under such LOC, the related LOC Application, all reimbursement obligations with respect to such LOC, and all collateral, guarantees and other rights from time to time directly or indirectly securing or supporting the foregoing (such interest of each Bank being referred to herein as an “LOC Participating Interest”, it being understood that the LOC Participating Interest of the Issuing Bank is the interest not otherwise attributable to the LOC Participating Interests of the other Banks). On the date that any assignee becomes a party to this Agreement in accordance with Section 8.07, LOC Participating Interests in all outstanding LOCs held by the Bank from which such assignee acquired its interest hereunder shall be proportionately reallocated between such assignee and such assignor Bank. Notwithstanding any other provision hereof, each Bank hereby agrees that its obligation to participate in each LOC, its obligation to make the payments specified in Section 2.02(f) and the right of the Issuing Bank to receive such payments in the manner specified therein are each absolute, irrevocable and unconditional and shall not be affected by any event, condition or circumstance whatever. The failure of any Bank to make any such

payment shall not relieve any other Bank of its funding obligation hereunder on the date due, but no Bank shall be responsible for the failure of any other Bank to meet its funding obligations hereunder.

(f) Payment by Banks on Account of Unreimbursed Draws. If the Issuing Bank makes a payment under an LOC and is not reimbursed in full therefor in accordance with Section 2.03, the Issuing Bank may notify the Administrative Agent thereof (which notice may be by telephone), and the Administrative Agent shall forthwith notify each Bank thereof (which notice may be by telephone promptly confirmed in writing). No later than the Administrative Agent’s close of business on the date such notice is given (if notice is given by 2:00 P.M. on a Business Day) or 10:00 A.M. on the following Business Day (if notice is given after 2:00 P.M. on a Business Day), each Bank will pay to the Administrative Agent, for the account of the Issuing Bank, in immediately available funds, an amount equal to such Bank’s Pro Rata Share of the unreimbursed portion of such payment by the Issuing Bank. Amounts received by the Administrative Agent for the account of the Issuing Bank shall be forthwith transferred, in immediately available funds, to the Issuing Bank. To the extent that any Bank fails to make such payment to the Administrative Agent for the account of the Issuing Bank on such date, such Bank shall pay such amount on demand, together with interest, for the Issuing Bank’s own account, from the date such payment is due from such Bank to the Issuing Bank to the date of payment to the Issuing Bank (before and after judgment) at a rate per annum for each day (i) from the date such payment is due from such Bank to the Issuing Bank to the third Business Day thereafter equal to the Federal Funds Rate and (ii) thereafter equal to the Base Rate.

(g) Advances. The term “Advance” is used in this Agreement in accordance with the meanings set forth in this Section 2.02(g). The making of any payment by the Issuing Bank under an LOC is sometimes referred to herein as the making of an Advance by the Issuing Bank in the amount of such payment. The making of any payment by a Bank for the account of the Issuing Bank under Section 2.02(f) on account of an unreimbursed drawing on an LOC is sometimes referred to as the making of an Advance by such Bank. The making of an Advance by a Bank with respect to an unreimbursed drawing on an LOC shall reduce, by a like amount, the outstanding Advance of the Issuing Bank with respect to such unreimbursed drawing.

(h) LOC Reports. The Issuing Bank will furnish to the Administrative Agent prompt written notice of each issuance or extension, or increase in the amount, of an LOC (including the Available Amount and expiration date thereof), amendment to an LOC, cancellation of an LOC and payment on an LOC. The Administrative Agent will furnish to each Bank prior to the fifteenth Business Day of each calendar quarter a written report summarizing issuance, extension and expiration dates of LOCs issued or extended during the preceding calendar quarter and payments and reductions in Available Amounts during such calendar quarter on all LOCs.

(a) ACE agrees to reimburse the Issuing Bank (by making payment to the Administrative Agent for the account of the Issuing Bank in accordance with Section 2.07) in the amount of each Advance made by the Issuing Bank, such reimbursement to be made on the date such Advance is made by the Issuing Bank (but not earlier than one Business Day after notice of the drawing giving rise to such Advance is given to ACE). Such reimbursement obligation shall

be payable without further notice, protest or demand, all of which are hereby waived, and an action therefor shall immediately accrue. To the extent such payment by ACE is not timely made, ACE agrees to pay to the Administrative Agent, for the respective accounts of the Issuing Bank and the Banks that have funded their respective shares of such amount remaining unpaid by ACE, on demand, default interest at a rate per annum equal to the Base Rate plus 2% for each day from the date on which ACE is to reimburse the Issuing Bank to the date such obligation is paid in full. For the avoidance of doubt, the payment by ACE of default interest pursuant to this Section 2.03(a) shall not affect the calculation of fees under the Loan Documents.

(b) The obligation of ACE to reimburse the Issuing Bank for any Advance made by the Issuing Bank, and the obligation of each Bank under Section 2.02(f) with respect thereto, shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement, the applicable LOC Application and any other applicable agreement or instrument under all circumstances, including the following circumstances:

(i) any lack of validity or enforceability of any Loan Document, any LOC Application, any LOC or any other agreement or instrument relating thereto (all of the foregoing, collectively, the “LOC Related Documents”);

(ii) any change in the time, manner or place of payment of, or in any other term of, any obligation of ACE or any other Person in respect of any LOC Related Document or any other amendment or waiver of or any consent to departure from any LOC Related Document;

(iii) the existence of any claim, set-off, defense or other right that ACE or any other Person may have at any time against any beneficiary or any transferee of an LOC (or any Person for which any such beneficiary or any such transferee may be acting), the Issuing Bank or any other Person, whether in connection with the transactions contemplated by the LOC Related Documents or any unrelated transaction;

(iv) any statement or any other document presented under an LOC proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(v) payment by the Issuing Bank under an LOC against presentation of a draft or certificate that does not strictly comply with the terms of such LOC;

(vi) any exchange, release or non-perfection of any collateral granted to secure any obligation of ACE or any other Person in connection with any Loan Document; or

(vii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, ACE.

(c) If any amount received by the Issuing Bank on account of any Advance shall be avoided, rescinded or otherwise returned or paid over by the Issuing Bank for any reason at any time, whether before or after the termination of this Agreement (or the Issuing Bank believes in good faith that such avoidance, rescission, return or payment is required, whether or not such

matter has been adjudicated), each Bank will (except to the extent a corresponding amount received by such Bank on account of its Advance relating to the same payment on an LOC has been avoided, rescinded or otherwise returned or paid over by such Bank), promptly upon notice from the Administrative Agent or the Issuing Bank, pay over to the Administrative Agent for the account of the Issuing Bank its Pro Rata Share of such amount, together with its Pro Rata Share of any interest or penalties payable with respect thereto.

2.04 Termination or Reduction of the Commitments. Subject to the Pricing Agreement, ACE may at any time, upon at least five Business Days’ notice to the Administrative Agent, terminate the Commitments in whole or reduce in part the unused portion of the Commitment Amounts; provided that each partial reduction (i) shall be in an aggregate amount of $10,000,000 or a higher integral multiple of $1,000,000 and (ii) shall be made ratably among the Banks in accordance with their Commitment Amounts. Concurrently with any termination of the Commitments in whole pursuant to this Section 2.04, ACE shall (a) surrender to the Issuing Bank, or provide cash collateral or backup letters of credit (in each case pursuant to documentation reasonably acceptable to the Administrative Agent and, in the case of backup letters of credit, from a financial institution acceptable to the Issuing Bank) in an amount equal to 102% of the Available Amount of, all outstanding LOCs and (b) pay the principal amount of all outstanding Advances, all accrued and unpaid default interest thereon, all accrued and unpaid fees payable pursuant to Section 2.05 and all other obligations then payable hereunder and under the other Loan Documents. If any LOCs remain outstanding at the time of termination of the Commitments pursuant to this Section 2.04, the Issuing Bank shall use reasonable commercial efforts to assist ACE in replacing such LOCs with letters of credit issued by other institutions.

(a) If, due to either (i) the introduction of or any change in or in the interpretation of, in each case after the date hereof, any law or regulation or (ii) compliance with any guideline or request issued after the date hereof from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Bank of agreeing to issue or of issuing or maintaining or participating in LOCs or the making of Advances (excluding, for purposes of this Section 2.06, any such increased costs resulting from (x) Taxes or Other Taxes (as to which Section 2.08 shall govern) and (y) changes in the basis of taxation of overall net income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Bank is organized or has its Lending Office or any political subdivision thereof), then ACE agrees to pay, from time to time, within five days after demand by such Bank (with a copy of such demand to the Administrative Agent), which demand shall include a statement of the basis for such demand and a calculation in reasonable detail of the amount demanded, to the Administrative Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost. A certificate as to the amount of such increased cost, submitted to ACE by such Bank, shall be conclusive and binding for all purposes, absent manifest error.

(b) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation, in each case after the date hereof, or (ii) compliance with any guideline or

request issued after the date hereof from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the amount of capital required or expected to be maintained by any Bank or any corporation controlling such Bank as a result of or based upon the existence of such Bank’s commitment to extend credit hereunder and other commitments of such type, then, within ten days after demand by such Bank or such corporation (with a copy of such demand to the Administrative Agent), which demand shall include a statement of the basis for such demand and a calculation in reasonable detail of the amount demanded, ACE agrees to pay to the Administrative Agent for the account of such Bank, from time to time as specified by such Bank, additional amounts sufficient to compensate such Bank in the light of such circumstances, to the extent that such Bank reasonably determines such increase in capital to be allocable to the existence of such Bank’s commitment to issue or participate in LOCs hereunder or to the issuance or maintenance of or participation in any LOC. A certificate as to such amounts submitted to ACE by such Bank shall be conclusive and binding for all purposes, absent manifest error.

(c) Each Bank shall promptly notify ACE and the Administrative Agent of any event of which it has actual knowledge that will result in, and will use reasonable commercial efforts available to it (and not, in such Bank’s good faith judgment, otherwise disadvantageous to such Bank) to mitigate or avoid, any obligation of ACE to pay any amount pursuant to Section 2.06(a) or 2.06(b) above or pursuant to Section 2.08 (and, if any Bank has given notice of any such event and thereafter such event ceases to exist, such Bank shall promptly so notify ACE and the Administrative Agent). Without limiting the foregoing, each Bank will designate a different Lending Office if such designation will avoid (or reduce the cost to ACE of) any event described in the preceding sentence and such designation will not, in such Bank’s good faith judgment, be otherwise disadvantageous to such Bank.

(d) Notwithstanding the provisions of Section 2.06(a), 2.06(b) or 2.08 (and without limiting Section 2.06(c) above), if any Bank fails to notify ACE of any event or circumstance that will entitle such Bank to compensation pursuant to Section 2.06(a), 2.06(b) or 2.08 within 120 days after such Bank obtains actual knowledge of such event or circumstance, then such Bank shall not be entitled to compensation from ACE for any amount arising prior to the date that is 120 days before the date on which such Bank notifies ACE of such event or circumstance.

(a) ACE shall make each payment hereunder irrespective of any right of counterclaim or set-off not later than 11:00 A.M. on the day when due, in U.S. dollars, to the Administrative Agent at such account as the Administrative Agent shall reasonably direct in immediately available funds, with payments being received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The Administrative Agent will promptly thereafter distribute to each Bank its portion of such payment in accordance with the terms hereof. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Bank assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) All computations of default interest on Advances when the Base Rate is determined by reference to DB’s prime rate shall be made by the Administrative Agent on the basis of a year of 365 or, if applicable, 366 days; all other computations of default interest shall be made by the Administrative Agent on the basis of a year of 360 days. All such computations shall be made for the actual number of days (including the first day but excluding the last day) occurring in the period for which such default interest is payable. Each determination by the Administrative Agent of a default interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(c) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall be included in the computation of any payment of default interest or fees.

(a) All payments by ACE hereunder shall be made, in accordance with Section 2.07, free and clear of and without deduction for, any present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and the Administrative Agent, taxes that are imposed on its overall net income by the United States and taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction under the laws of which such Bank or the Administrative Agent, as the case may be, is organized or any political subdivision thereof and, in the case of each Bank, taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction of such Bank’s Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder, “Taxes”). If ACE shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Bank or the Administrative Agent, (i) the sum payable by ACE shall be increased as may be necessary so that after ACE and the Administrative Agent have made all required deductions (including deductions applicable to additional sums payable under this Section 2.08) such Bank or the Administrative Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) ACE shall make all such deductions and (iii) ACE shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, ACE shall pay any present or future stamp, documentary, excise, property or similar taxes, charges or levies that arise from any payment made hereunder or from the execution, delivery or registration of, performance under, or otherwise with respect to, this Agreement or any other Loan Document (any of the foregoing, “Other Taxes”).

(c) ACE shall indemnify each Bank and the Administrative Agent for and hold each of them harmless against the full amount of Taxes and Other Taxes, and for the full amount of taxes of any kind imposed by any jurisdiction on amounts payable under this Section 2.08, imposed on or paid by such Bank or the Administrative Agent (as the case may be) and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. Any such indemnification payment shall be made within 30 days from the date such Bank or the Administrative Agent (as the case may be) makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes, ACE shall furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment. In the case of any payment hereunder by or on behalf of ACE through an account or branch outside the United States or by or on behalf of ACE by a payor that is not a United States person, if ACE determines that no Taxes are payable in respect thereof, ACE shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at such address, an opinion of counsel acceptable to the Administrative Agent stating that such payment is exempt from Taxes. For purposes of this Section 2.08(d) and Section 2.08(e), the terms “United States” and “United States person” shall have the meanings specified in Sections 7701(a)(9) and 7701(a)(10) of the Internal Revenue Code, respectively.

(e) Each Bank organized under the laws of a jurisdiction outside the United States shall, on or prior to the date of its execution and delivery of this Agreement in the case of each initial Bank, and on the date of the Assignment and Acceptance pursuant to which it becomes a Bank in the case of each other Bank, and from time to time thereafter as requested in writing by ACE (but only so long as such Bank remains lawfully able to do so), provide each of the Administrative Agent and ACE with two original Internal Revenue Service forms W-8BEN or W-8ECI or (in the case of a Bank that has certified in writing to the Administrative Agent that it is not a “bank” as defined in Section 881(c)(3)(A) of the Internal Revenue Code) form W-8 (and, if such Bank delivers a form W-8, a certificate representing that such Bank is not a “bank” for purposes of Section 881(c)(3)(A) of the Internal Revenue Code, is not a 10-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of ACE and is not a controlled foreign corporation related to ACE (within the meaning of Section 864(d)(4) of the Internal Revenue Code)), as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Bank is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or, in the case of a Bank providing a form W-8, certifying that such Bank is a foreign corporation, partnership, estate or trust. If the forms provided by a Bank at the time such Bank first becomes a party to this Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Bank provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate shall be considered excluded from Taxes only for periods governed by such forms; provided that if, at the effective date of the Assignment and Acceptance pursuant to which a Bank becomes a party to this Agreement, the Bank assignor was entitled to payments under Section 2.08(a) in respect of United States withholding tax with respect to default interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Bank assignee on such date. If any form or document referred to in this Section 2.08(e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service form W-8BEN, W-8ECI or W-8 (and the related certificate described above), that the Bank reasonably considers to be confidential, the Bank shall give notice thereof to ACE and shall not be obligated to include in such form or document such confidential information.

(f) For any period with respect to which a Bank which may lawfully do so has failed to provide ACE with the appropriate form described in Section 2.08(e) above (other than if such

failure is due to a change in law occurring after the date on which a form originally was required to be provided or if such form otherwise is not required under Section 2.08(e) above), such Bank shall not be entitled to indemnification under Sections 2.08(a) or 2.08(c) with respect to Taxes imposed by the United States by reason of such failure; provided that should a Bank become subject to Taxes because of its failure to deliver a form required hereunder, ACE shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Taxes.

(g) Each Bank represents and warrants to ACE that, as of the date such Bank becomes a party to this Agreement, such Bank is entitled to receive payments hereunder from ACE without deduction or withholding for or on account of any Taxes.

2.09 Sharing of Payments, Etc. If any Bank shall obtain at any time any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise, other than as a result of an assignment pursuant to Section 8.07) (a) on account of obligations due and payable to such Bank hereunder at such time in excess of its ratable share (according to the proportion of (i) the amount of such obligations due and payable to such Bank at such time to (ii) the aggregate amount of the obligations due and payable to all Banks hereunder at such time) of payments on account of the obligations due and payable to all Banks hereunder at such time obtained by all the Banks at such time or (b) on account of obligations owing (but not due and payable) to such Bank hereunder at such time in excess of its ratable share (according to the proportion of (i) the amount of such obligations owing to such Bank at such time to (ii) the aggregate amount of the obligations owing (but not due and payable) to all Banks hereunder at such time) of payments on account of the obligations owing (but not due and payable) to all Banks hereunder at such time obtained by all of the Banks at such time, such Bank shall forthwith purchase from the other Banks such interests or participating interests in the obligations due and payable or owing to them, as the case may be, as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them; provided that if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, such purchase from each other Bank shall be rescinded and such other Bank shall repay to the purchasing Bank the purchase price to the extent of such Bank’s ratable share (according to the proportion of (i) the purchase price paid to such Bank to (ii) the aggregate purchase price paid to all Banks) of such recovery together with an amount equal to such Bank’s ratable share (according to the proportion of (A) the amount of such other Bank’s required repayment to (B) the total amount so recovered from the purchasing Bank) of any interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered. ACE agrees that any Bank so purchasing an interest or participating interest from another Bank pursuant to this Section 2.09 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such interest or participating interest, as the case may be, as fully as if such Bank were the direct creditor of ACE in the amount of such interest or participating interest, as the case may be.

2.10 Use of Letters of Credit. The LOCs shall be used for general corporate purposes of ACE and its Subsidiaries.

2.11 Replacement of Affected Bank or Nonconsenting Bank. At any time any Bank (other than the Issuing Bank) is an Affected Bank or a Nonconsenting Bank, ACE may, at its sole expense (including the assignment fee specified in Section 8.07(a)) and effort, replace such

Affected Bank or Nonconsenting Bank as a party to this Agreement with one or more other Banks and/or Eligible Assignees, and upon notice from ACE such Affected Bank or Nonconsenting Bank shall assign pursuant to an Assignment and Acceptance, and without recourse or warranty, its Commitment Amount, its LOC Participating Interests, its Advances and all of its other rights and obligations hereunder to such other Banks and/or Eligible Assignees for a purchase price equal to the sum of the principal amount of the Advances so assigned, all accrued and unpaid default interest thereon, such Affected Bank’s or Nonconsenting Bank’s ratable share of all accrued and unpaid fees payable pursuant to Section 2.05 and all other obligations owed to such Affected Bank or Nonconsenting Bank hereunder and under the other Loan Documents. Notwithstanding the foregoing, (i) no Affected Bank or Nonconsenting Bank shall be required to make any such assignment if, prior to its receipt of the notice from ACE referred to in the foregoing sentence, as a result of a waiver or otherwise, the circumstances entitling ACE to require such assignment cease to apply, and (ii) no Nonconsenting Bank shall be required to make any such assignment if at the time of any such proposed assignment, any Default under this Agreement has occurred and is continuing.

(a) LOC Applications. The representations, warranties and covenants by ACE under, and the rights and remedies of the Issuing Bank under, any LOC Application relating to any LOC are in addition to, and not in limitation or derogation of, representations, warranties and covenants by ACE under, and rights and remedies of the Issuing Bank and the other Banks under, this Agreement and applicable law. ACE acknowledges and agrees that all rights of the Issuing Bank under any LOC Application shall inure to the benefit of each Bank to the extent of its LOC Participating Interest in and Advances in connection with the applicable LOC as fully as if such Bank were a party to such LOC Application. In the event of any inconsistency between the terms of this Agreement and any LOC Application, this Agreement shall prevail.

(b) Certain Provisions. The Issuing Bank shall have no duties or responsibilities to the Administrative Agent or any Bank except those expressly set forth in this Agreement, and no implied duties or responsibilities on the part of the Issuing Bank shall be read into this Agreement or shall otherwise exist. The duties and responsibilities of the Issuing Bank to the Banks and the Administrative Agent under this Agreement and the other Loan Documents shall be mechanical and administrative in nature, and the Issuing Bank shall not have a fiduciary relationship in respect of the Administrative Agent, any Bank or any other Person. The Issuing Bank shall not be liable for any action taken or omitted to be taken by it under or in connection with this Agreement or any Loan Document or LOC, except to the extent resulting from its gross negligence or willful misconduct, as finally determined by a court of competent jurisdiction. The Issuing Bank shall not be under any obligation to ascertain, inquire or give any notice to the Administrative Agent or any Bank relating to (i) the performance or observance of any of the terms or conditions of this Agreement or any other Loan Document on the part of ACE, (ii) the business, operations, condition (financial or otherwise) or prospects of ACE or any other Person, or (iii) the existence of any Default. The Issuing Bank shall not be under any obligation, either initially or on a continuing basis, to provide the Administrative Agent or any Bank with any notices, reports or information of any nature, whether in its possession presently or hereafter, except for such notices, reports and other information expressly required by this Agreement to be so furnished. The Issuing Bank shall not be responsible for the execution, delivery, effectiveness, enforceability, genuineness, validity or adequacy of this Agreement or any Loan Document.

(c) Administration. The Issuing Bank may rely upon any notice or other communication of any nature (written, electronic or oral, including telephone conversations and transmissions through the Issuing Bank’s remote access system, whether or not such notice or other communication is made in a manner permitted or required by this Agreement or any other Loan Document) purportedly made by or on behalf of the proper party or parties, and the Issuing Bank shall not have any duty to verify the identity or authority of any Person giving such notice or other communication. The Issuing Bank may consult with legal counsel (including its in-house counsel or in-house or other counsel for ACE), independent public accountants and any other experts selected by it from time to time, and the Issuing Bank shall not be liable for any action taken or omitted to be taken in good faith in accordance with the advice of such counsel, accountants or experts. Whenever the Issuing Bank shall deem it necessary or desirable that a matter be proved or established with respect to ACE, the Administrative Agent or any Bank, such matter may be established by a certificate of ACE, the Administrative Agent or such Bank, as the case may be, and the Issuing Bank may conclusively rely upon such certificate. The Issuing Bank shall not be deemed to have any knowledge or notice of the occurrence of any Default unless the Issuing Bank has received notice from a Bank, the Administrative Agent or ACE referring to this Agreement, describing such Default, and stating that such notice is a “notice of default”.

(d) Indemnification of Issuing Bank by Banks. Each Bank hereby agrees to reimburse and indemnify the Issuing Bank and each of its directors, officers, employees and agents (to the extent not reimbursed by ACE and without limitation of the obligations of ACE to do so), in accordance with its Pro Rata Share, from and against any and all amounts, losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements of any kind or nature (including the reasonable fees and disbursements of counsel (other than in-house counsel) for the Issuing Bank or such other Person in connection with any investigative, administrative or judicial proceeding commenced or threatened, whether or not the Issuing Bank or such other Person shall be designated a party thereto) that may at any time be imposed on, incurred by or asserted against the Issuing Bank, in its capacity as such, or such other Person, as a result of, or arising out of, or in any way related to or by reason of, this Agreement, any other Loan Document or any LOC, any transaction from time to time contemplated hereby or thereby, or any transaction financed in whole or in part or directly or indirectly with the proceeds of any LOC, provided that no Bank shall be liable for any portion of such amounts, losses, liabilities, claims, damages, expenses, obligations, penalties, actions, judgments, suits, costs or disbursements to the extent resulting from the gross negligence or willful misconduct of the Issuing Bank or such other Person, as finally determined by a court of competent jurisdiction.

(e) Issuing Bank in its Individual Capacity. With respect to its commitments and the obligations owing to it, the Issuing Bank shall have the same rights and powers under this Agreement and each other Loan Document as any other Bank and may exercise the same as though it were not the Issuing Bank, and the term “Banks” and like terms shall include the Issuing Bank in its individual capacity as such. The Issuing Bank and its Affiliates may, without liability to account to any Person, make loans to, accept deposits from, acquire debt or equity

interests in, act as trustee under indentures of, act as agent under other credit facilities for, and engage in any other business with, ACE and any stockholder, Subsidiary or Affiliate of ACE, as though the Issuing Bank were not the Issuing Bank hereunder.

2.13 Failure of Issuing Bank to be an Eligible Issuer. If at any time the Issuing Bank ceases to be a Qualifying Issuing Bank, then (a) at the request of ACE, Deutsche Bank AG, New York Branch shall cause Deutsche Bank Trust Company Americas, if it then is a Qualifying Issuing Bank, to be substituted as the Issuing Bank as promptly as practicable thereafter with respect to all subsequent LOCs issued pursuant to this Agreement and (b) if Deutsche Bank Trust Company Americas is not, or subsequently ceases to be, a Qualifying Issuing Bank, the Issuing Bank shall use reasonable commercial efforts in cooperation with ACE to find a substitute Qualifying Issuing Bank as promptly as practicable thereafter which is reasonably satisfactory to ACE to replace the Issuing Bank with respect to all subsequent LOCs issued pursuant to this Agreement. With respect to any LOC outstanding at the time a substitute Qualifying Issuing Bank becomes the Issuing Bank hereunder, the existing Issuing Bank shall use reasonable commercial efforts to assist ACE in replacing such existing LOC with a letter of credit issued by the new Issuing Bank.

3.01 Conditions Precedent to Closing Date. The occurrence of the Closing Date, and the obligation of the Issuing Bank to issue any LOC, is subject to the satisfaction of the following conditions precedent:

(a) The Administrative Agent shall have received the following, each dated the Closing Date (unless otherwise specified), in form and substance reasonably satisfactory to the Administrative Agent (unless otherwise specified) and in sufficient copies for each Bank:

(i) Certified copies of the resolutions of the Board of Directors of ACE approving the transactions contemplated by the Loan Documents.

(ii) A certificate of ACE, signed by a Responsible Officer, certifying as to (1) the truth of the representations and warranties contained in the Loan Documents as though made on and as of the Closing Date and (2) the absence of any Default.

(iv) Favorable opinions of (1) Niederer Kraft & Frey AG, Swiss counsel for ACE, in substantially the form of Exhibit E-1, and (2) Mayer Brown LLP, New York counsel for ACE, in substantially the form of Exhibit E-2.

(b) There shall exist no action, suit, investigation, litigation or proceeding affecting ACE or any of its Subsidiaries pending or threatened before any court, governmental agency or

arbitrator that (x) would be reasonably expected to have a Material Adverse Effect or (y) would reasonably be expected to materially adversely affect the legality, validity or enforceability of any Loan Document or the transactions contemplated thereby.

(c) ACE shall have paid all fees of the Administrative Agent and the Banks and all expenses of the Administrative Agent (including the fees and expenses of counsel to the Administrative Agent), in each case to the extent then due and payable.

3.02 Conditions Precedent to Each Issuance, Extension or Increase of an LOC. In addition to the conditions to issuance, extension or increase set forth in Section 2.01, the obligation of the Issuing Bank to issue, extend or increase the amount of an LOC (including any issuance on the Closing Date) shall be subject to the further conditions precedent that on the date of such issuance, extension or increase (a) the following statements shall be true (and each request for issuance, extension or increase of an LOC and each automatic extension of an LOC shall constitute a representation and warranty by ACE that both on the date of such notice and on the date of such issuance, extension or increase such statements are true):

(i) the representations and warranties contained in each Loan Document are correct in all material respects on and as of such date, before and after giving effect to such issuance, extension or increase, as though made on and as of such date, other than any such representation or warranty that, by its terms, refers to a specific date other than the date of such issuance, extension or increase, in which case as of such specific date (provided that the representation and warranty contained in the last sentence of Section 4.06 shall be excluded from this clause (i) at all times after (but shall be included on and as of) the Closing Date); and

(ii) no Default has occurred and is continuing or would result from such issuance, extension or increase; and

(b) the Administrative Agent shall have received such other approvals, opinions or documents as any Bank through the Administrative Agent may reasonably request.

4.01 Existence, Etc. ACE and each of its Material Subsidiaries (i) is duly organized or formed, validly existing and, to the extent such concept applies, in good standing under the laws of the jurisdiction of its incorporation or formation, except, in the case of any Material Subsidiary, where the failure to do so would not be reasonably likely to have a Material Adverse Effect, (ii) is duly qualified and in good standing as a foreign corporation or other entity in each other jurisdiction in which it owns or leases property or in which the conduct of its business requires it to so qualify or be licensed except where the failure to so qualify or be licensed would not be reasonably likely to have a Material Adverse Effect and (iii) has all requisite power and authority (including all governmental licenses, permits and other approvals) to own or lease and operate its properties and to carry on its business as now conducted and as proposed to be conducted, except where the failure to have any license, permit or other approval would not be reasonably likely to have a Material Adverse Effect.

4.02 Authority and Authorization. The execution, delivery and performance by ACE of each Loan Document, and the consummation of the transactions contemplated thereby, are within the organizational powers of ACE, have been duly authorized by all necessary organizational action, and do not (i) contravene the constitutional documents of ACE, (ii) violate any law, rule, regulation (including Regulation X of the Board of Governors of the Federal Reserve System), order, writ, judgment, injunction, decree, determination or award, (iii) conflict with or result in the breach of, or constitute a default under, any contract, loan agreement, indenture, mortgage, deed of trust, lease or other instrument binding on or affecting ACE or any of its Subsidiaries or any of their respective properties or (iv) result in or require the creation or imposition of any Lien upon or with respect to any of the properties of ACE or any of its Subsidiaries. Neither ACE nor any of its Subsidiaries is in violation of any such law, rule, regulation, order, writ, judgment, injunction, decree, determination or award or in breach of any such contract, loan agreement, indenture, mortgage, deed of trust, lease or other instrument, the violation or breach of which would be reasonably likely to have a Material Adverse Effect.

4.03 Approvals. No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body or any other third party is required for (i) the due execution, delivery or performance by ACE of any Loan Document or the consummation of the transactions contemplated thereby or (ii) the exercise by the Administrative Agent or any Bank of its rights under the Loan Documents, except for the authorizations, approvals, actions, notices and filings that have been duly obtained, taken, given or made and are in full force and effect, subject to bankruptcy, insolvency and similar laws of general application relating to creditors’ rights and to general principles of equity.

4.04 Enforceability. This Agreement has been, and each other Loan Document has been or when delivered hereunder will have been, duly executed and delivered by ACE. This Agreement is, and each other Loan Document is or when delivered hereunder will be, the legal, valid and binding obligation of ACE, enforceable against ACE in accordance with its terms.

4.05 Litigation. There is no action, suit, investigation, litigation or proceeding affecting ACE or any of its Subsidiaries pending or, to the knowledge of ACE, threatened before any court, governmental agency or arbitrator that (i) would be reasonably likely to have a Material Adverse Effect or (ii) would reasonably be expected to affect the legality, validity or enforceability of any Loan Document or the transactions contemplated by the Loan Documents.

4.06 Financials. The Consolidated balance sheet of ACE and its Subsidiaries as at December 31, 2008, and the related Consolidated statements of income and of cash flows of ACE and its Subsidiaries for the fiscal year then ended, accompanied by an unqualified opinion of PricewaterhouseCoopers LLP, independent public accountants, and the Consolidated balance sheet of ACE and its Subsidiaries as at March 31, 2009, and the related Consolidated statements of income and cash flows of ACE and its Subsidiaries for the three months then ended, duly certified by the Chief Financial Officer of ACE, copies of which have been furnished to each Bank, fairly present, subject, in the case of said balance sheet as at March 31, 2009, and said statements of income and cash flows for the three months then ended, to year-end audit

adjustments, the Consolidated financial condition of ACE and its Subsidiaries as at such dates, and the Consolidated results of operations of ACE and its Subsidiaries for the periods ended on such dates, all in accordance with GAAP applied on a consistent basis (subject in the case of the March 31, 2009 balance sheet and statements of income and cash flows, to the absence of footnotes). Since December 31, 2008, there has been no Material Adverse Change.

4.07 Accuracy of Information. No written information, exhibit or report furnished by or on behalf of ACE to the Administrative Agent or any Bank in connection with the negotiation of the Loan Documents or pursuant to the terms of the Loan Documents contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements made therein not misleading as at the date it was dated (or if not dated, so delivered).

4.08 Margin Stock. Margin stock (as defined in Regulation U of the Board of Governors of the Federal Reserve System) constitutes less than 25% of the value of those assets of ACE that are subject to any limitation on sale, pledge or other disposition hereunder.

4.09 Compliance with Certain Acts. ACE and each of its Subsidiaries is in compliance in all material respects with the Patriot Act. No part of any payment under any LOC will be used, directly or indirectly, for any payments to any governmental official or employee, political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper advantage, in violation of the United States Foreign Corrupt Practices Act of 1977.

4.10 Reimbursement Agreement Representations and Warranties. Each representation and warranty of ACE set forth in clauses (j), (k), (l), (m), (n) and (p) of Section 4.01 of the Reimbursement Agreement is true and correct in all material respects as if set forth in full herein, mutatis mutandis.

So long as any Advance or any other obligation of ACE under any Loan Document shall remain unpaid, any LOC shall be outstanding or the Issuing Bank shall have any commitment to issue any LOC, ACE will:

5.01 Pari Passu Ranking. Ensure that at all times the claims of the Banks, the Issuing Bank and the Administrative Agent against it under the Loan Documents will rank at least pari passu with the claims of all its other unsecured and unsubordinated creditors, except for claims that are preferred by any bankruptcy, insolvency, liquidation or other similar laws of general application.

5.02 Other Covenants. Comply with all covenants set forth in Article V of the Reimbursement Agreement as if such covenants were set forth in full herein, mutatis mutandis.

6.01 Events of Default and Their Effect. If any of the following events (each an “Event of Default”) shall occur and be continuing:

(a) ACE shall fail to pay any reimbursement obligation in respect of any Advance made by the Issuing Bank pursuant to an LOC when and as the same shall become due and payable; or ACE shall fail to pay any other amount payable by ACE under any Loan Document within five Business Days after the same becomes due and payable;

(b) Any representation or warranty made by ACE (or any of its officers) under or in connection with any Loan Document shall prove to have been incorrect in any material respect when made;

(c) (i) ACE shall fail to perform or observe any term, covenant or agreement contained in Section 2.10, or in Section 5.01(d) (solely with respect to ACE), 5.02, 5.03(a) or 5.04 of the Reimbursement Agreement as incorporated herein by reference; (ii) ACE shall fail to perform or observe any term, covenant or agreement contained in Section 5.01(e) of the Reimbursement Agreement if such failure shall remain unremedied for five Business Days after written notice thereof shall have been given to ACE by the Administrative Agent or any Bank; or (iii) ACE shall fail to perform or observe any other term, covenant or agreement contained or incorporated by reference herein or contained in any Loan Document on its part to be performed or observed if such failure shall remain unremedied for 30 days after the earlier of the date on which (A) a Responsible Officer becomes aware of such failure or (B) written notice thereof shall have been given to ACE by the Administrative Agent or any Bank;

(d) Any “Event of Default” (under and as defined in the Reimbursement Agreement) shall occur and be continuing under Section 6.01(f), (g), (h), (j), (k) or (l) of the Reimbursement Agreement; or

(e) Any event of the type described in Section 6.01(f) of the Reimbursement Agreement shall occur with respect to the Reimbursement Agreement; provided, that for purposes of this Section 6.01(e) only, the references to “Reimbursement Agreement” herein shall include any modifications or amendments to the Reimbursement Agreement as in effect on any determination date;

then, and in any such event, the Administrative Agent (i) shall at the request, or may with the consent, of the Required Banks, by notice to ACE, declare the obligation of the Issuing Bank to issue, extend or increase the amount of any LOC to be terminated, whereupon the same shall forthwith terminate, and/or (ii) shall at the request, or may with the consent, of the Required Banks, by notice to ACE, declare all amounts payable under this Agreement and the other Loan Documents to be forthwith due and payable, whereupon all such amounts shall become and be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by ACE, and/or (iii) may require the beneficiary of any LOC to draw the entire amount available to be drawn under such LOC in accordance with (and

to the extent permitted by) such LOC; provided that in the event of an actual or deemed entry of an order for relief with respect to ACE under the federal Bankruptcy Law, (x) the obligation of the Issuing Bank to issue, extend or increase the amount of any LOC shall automatically terminate, (y) all such amounts shall automatically become due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby expressly waived by ACE and (z) the obligation of ACE to provide cash collateral under Section 6.02 shall automatically become effective.

6.02 Actions in Respect of the Letters of Credit upon Default. If any Event of Default shall have occurred and be continuing, the Administrative Agent may, or shall at the request of the Required Banks, whether before or after taking any of the actions described in Section 6.01, demand that ACE, and forthwith upon such demand ACE will, pay to the Administrative Agent on behalf of the Banks in immediately available funds an amount equal to the aggregate Available Amount of all LOCs then outstanding as cash collateral. If at any time during the continuance of an Event of Default the Administrative Agent determines that such funds are subject to any right or claim of any Person other than the Administrative Agent and the Banks or that the total amount of such funds is less than the aggregate Available Amount of all LOCs, ACE will, forthwith upon demand by the Administrative Agent, pay to the Administrative Agent, as additional cash collateral, an amount equal to the excess of (a) such aggregate Available Amount over (b) the total amount of funds, if any, that the Administrative Agent determines to be free and clear of any such right and claim. Upon the drawing of any LOC, such funds shall be applied to reimburse the Issuing Bank, to the extent permitted by applicable law.

7.01 Authorization and Action. Each Bank (in its capacity as a Bank) hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement and the other Loan Documents as are delegated to the Administrative Agent by the terms hereof and thereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters not expressly provided for by the Loan Documents, the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in acting or refraining from acting) upon the instructions of the Required Banks (or all Banks where unanimity is required), and such instructions shall be binding upon all Banks; provided that the Administrative Agent shall not be required to take any action that exposes the Administrative Agent to personal liability or that is contrary to this Agreement or applicable law. The Administrative Agent agrees to give each Bank prompt notice of each notice given to it by ACE pursuant to the terms of this Agreement.

7.02 Administrative Agent’s Reliance, Etc. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may consult with legal counsel (including counsel for ACE), independent public accountants and other experts selected by it and shall not be liable for any

action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (b) makes no warranty or representation to any Bank and shall not be responsible to any Bank for any statement, warranty or representation (whether written or oral) made in or in connection with the Loan Documents (except for statements, warranties and representations made to ACE in the Pricing Agreement); (c) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any Loan Document on the part of ACE or to inspect the property (including the books and records) of ACE; (d) shall not be responsible to any Bank for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any Lien created or purported to be created under or in connection with, any Loan Document or any other instrument or document furnished pursuant thereto; and (e) shall incur no liability under or in respect of any Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by facsimile) reasonably believed by it to be genuine and signed or sent by the proper party or parties.

7.03 The Administrative Agent and Affiliates. With respect to its Commitment, its Participating Interests and the Advances, the Administrative Agent shall have the same rights and powers under the Loan Documents as any other Bank and may exercise the same as though it were not the Administrative Agent; and the term “Bank” or “Banks” shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. The Administrative Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, ACE, any of its Subsidiaries and any Person that may do business with or own securities of ACE or any such Subsidiary, all as if the Administrative Agent were not the Administrative Agent and without any duty to account therefor to the Banks.

7.04 Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Bank and based on the financial statements and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Bank 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.

(a) Indemnification. Each Bank severally agrees to indemnify the Administrative Agent and its officers, directors, employees, agents, advisors and Affiliates (to the extent not promptly reimbursed by ACE) from and against such Bank’s Pro Rata Share of all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent or any such other Person in any way relating to or arising out of the Loan Documents or any action taken or omitted by the Administrative Agent under the Loan Documents; provided that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s or such other Person’s gross negligence or willful misconduct. Without limitation of the foregoing, each Bank agrees to reimburse the Administrative Agent promptly upon demand for its Pro Rata Share of any costs and expenses (including fees and expenses of counsel) payable by ACE under Section 8.04, to the extent that

the Administrative Agent is not promptly reimbursed for such costs and expenses by ACE. The failure of any Bank to reimburse the Administrative Agent promptly upon demand for its Pro Rata Share of any amount required to be paid by the Banks to the Administrative Agent as provided herein shall not relieve any other Bank of its obligation hereunder to reimburse the Administrative Agent for its Pro Rata Share of such amount, but no Bank shall be responsible for the failure of any other Bank to reimburse the Administrative Agent for such other Bank’s Pro Rata Share of such amount. Without prejudice to the survival of any other agreement of any Bank hereunder, the agreement and obligations of each Bank contained in this Section 7.04(a) shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

7.05 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and ACE. Upon any such resignation or removal of the Administrative Agent, the Required Banks shall have the right to appoint a successor Administrative Agent, subject (so long as no Event of Default exists) to the consent of ACE (which consent shall not be unreasonably withheld). If no successor Administrative Agent shall have been so appointed by the Required Banks, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Required Banks’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $250,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent such successor Administrative Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under the Loan Documents. If within 45 days after written notice is given of the retiring Administrative Agent’s resignation or removal under this Section 7.05 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45^th day (i) the retiring Administrative Agent’s resignation or removal shall become effective, (ii) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (iii) the Required Banks shall thereafter perform all duties of the retiring Administrative Agent under the Loan Documents until such time, if any, as the Required Banks appoint a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent shall have become effective, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.

8.01 Amendments, Etc. No amendment or waiver of any provision of this Agreement or any other Loan Document, nor consent to any departure by ACE therefrom, shall in any event be effective unless the same shall be in writing and signed by the Required Banks (and, in the case of an amendment, ACE), and then any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided that no amendment, waiver or consent shall:

provided, further, that (x) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent in addition to the Banks required above to take such action, affect the rights or duties of the Administrative Agent under this Agreement or any other Loan Document and (y) no amendment, waiver or consent shall, unless in writing and signed by the Issuing Bank in addition to the Banks required above to take such action, affect the rights or duties of the Issuing Bank under this Agreement or any other Loan Document.

The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

(a) ACE agrees to pay on demand (i) all reasonable and documented costs and expenses of the Administrative Agent and the Issuing Bank (including the reasonable and documented fees and expenses of a single counsel for the Administrative Agent and the Issuing Bank) in connection with the preparation, execution, delivery, administration, modification and amendment of the Loan Documents; and (ii) all reasonable and documented costs and expenses of the Administrative Agent and each Bank in connection with the enforcement of the Loan Documents, whether in any action, suit or litigation, or any bankruptcy, insolvency or other similar proceeding affecting creditors’ rights generally (including the reasonable and documented fees and expenses of counsel for the Administrative Agent and each Bank with respect thereto); provided that ACE shall only be obligated to pay the fees and expenses of a single counsel for the Banks (as opposed to the Administrative Agent and the Issuing Bank) unless, and to the extent that, such counsel reasonably determines that a conflict requires the engagement of additional counsel.

(b) ACE agrees to indemnify and hold harmless the Administrative Agent and each Bank and each of their respective Affiliates and the officers, directors, employees, agents and advisors of any of the foregoing (each an “Indemnified Party”) from and against all claims, damages, losses, liabilities and expenses (including reasonable and documented fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party arising out of or in connection with or by reason of (including in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) this Agreement, the actual or proposed use of the proceeds of the Advances, the other Loan Documents or any transaction contemplated hereby or thereby, except to the extent such claim, damage, loss, liability or expense 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 such Indemnified Party or any of its Affiliates; provided that ACE shall only be obligated to pay the fees and expenses of a single counsel for the Indemnified Parties (other than the Administrative Agent and the Issuing Bank, which may engage separate counsel) unless, and to the extent that, such counsel reasonably determines that a conflict requires the engagement of additional counsel. In the case of any investigation, litigation or other proceeding to which the indemnity in this Section 8.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by ACE, its directors, shareholders or creditors or an Indemnified Party or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated by the Loan Documents are consummated. ACE also agrees not to assert any claim against any Indemnified Party, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to this Agreement, any other Loan Document, any transaction contemplated hereby or thereby or the actual or proposed use of the Advances or any LOC.

The Administrative Agent and each Bank agree promptly to notify ACE after any such set-off and application; provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Administrative Agent and each Bank and their respective Affiliates under this Section 8.05 are in addition to other rights and remedies (including other rights of set-off) that the Administrative Agent, such Bank and their respective Affiliates may have.
