AMOUNTS AND TERMS OF LETTERS OF CREDIT

2.01 Letters of Credit. The Bank agrees to (x) issue standby letters of credit (each an “LOC” and collectively the “LOCs”) for the account of ACE or for the account of any Wholly-owned Subsidiary of ACE, provided that ACE shall be a joint applicant and account party with respect to any such LOC, and (y) extend the expiration date for or increase the amount of LOCs, in each case from time to time on any Business Day during the Availability Period; provided that (a) the 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 Commitment Amount; or (ii) such issuance, extension or increase would conflict with or cause the Bank to exceed any limit imposed by applicable law or any applicable requirement thereof; (b) each LOC shall be denominated in Dollars, Sterling, Euro or another currency requested by ACE and acceptable to the Bank in its sole discretion; (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 scheduled Final Expiration Date; (e) each Lloyd’s LOC shall be issued for the benefit of Lloyd’s in the form at the time of issue required by Lloyd’s for the purposes of being eligible to be included in the Funds at Lloyd’s of a Member; (f) each Lloyd’s LOC shall be issued for the purposes of being included in the Funds at Lloyd’s of a Member that is a Wholly-owned Subsidiary of ACE and is not a member of any syndicate at Lloyd’s other than the Syndicate; (g) the Bank shall not have any obligation to issue any LOC (other than a Lloyd’s LOC) that the Bank determines, in the exercise of its reasonable judgment consistent with its customary practice, is unsatisfactory in form or substance; and (h) the Bank shall not have any obligation to issue an LOC that is to be issued in favor of a beneficiary that is a Sanctioned Person or is

organized under the laws of a Sanctioned Country. An LOC may by its terms be automatically extendible annually; provided that the Bank shall not be required to permit any such automatic extension if the Bank has determined that it would have no obligation at such time to issue such LOC as extended under the terms hereof, in which case the Bank shall notify the beneficiary thereof of its election not to extend such LOC (which the Bank agrees to do on and subject to the terms of Section 2.02(c)).

2.02 Issuance and Extensions and Drawings of LOCs.

(a) Request for Issuance. ACE may from time to time during the Availability Period request, upon at least three Business Days’ notice (given not later than 11:00 A.M.), that the Bank issue an LOC by delivering to the Bank (i) 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 Stated Amount thereof and the name and address of the beneficiary thereof; and (ii) such other information and documents as the Bank reasonably requires in accordance with its 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 Bank shall issue the requested LOC on the date specified in such LOC Application. Upon the issuance of an LOC, the Bank shall (A) deliver the original of such LOC to the beneficiary thereof or as ACE shall otherwise direct and (B) furnish a copy thereof to ACE. The Bank may issue LOCs through any branch or Affiliate thereof that (x) customarily issues letters of credit and (y) is an Approved Credit Institution and a Qualifying Bank or is otherwise approved in writing by ACE.

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

(c) Automatic Extensions. If any LOC provides for the automatic extension of the expiry date thereof unless the Bank gives notice that such expiry date shall not be extended, then the Bank shall allow such LOC to be extended; provided that (i) the Bank may give a notice of non-extension with respect to such an LOC if, at the time of the giving of such notice, (x) the conditions precedent to the issuance of a replacement for such LOC are not satisfied; or (y) the LOC would otherwise be automatically extended beyond the Final Expiration Date (and, if the Bank gives such a notice, the Bank will concurrently provide a copy thereof to ACE); and (ii) the Bank shall give a notice of non-extension with respect to such an LOC if the Bank receives, at least 10 Business Days prior to the date on which such notice of non-extension must be delivered under such LOC (or such shorter period as may acceptable to the Bank), notice from ACE directing the Bank not to permit the extension of such LOC.

(d) Illegality. If (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) shall, in either case, make it unlawful for the Bank to issue or maintain letters of credit, then (A) the Bank shall promptly notify ACE of the foregoing; (B) so long as it is unlawful for the Bank to issue letters of credit, the Bank shall not have any obligation to issue any LOC (and ACE shall have no obligation to pay any commitment fee pursuant to Section 2.05 with respect to the period of such unlawfulness); and (C) if it is unlawful for the Bank to maintain any outstanding LOC, ACE shall use reasonable commercial efforts to procure the return of such LOC from the beneficiary thereof (whether by obtaining a replacement letter of credit from another issuing bank or otherwise).

(e) Breach of Lloyd’s Rules. If the Managing Agent, the Syndicate or any Supported Member is in breach of any rule, regulation, requirement or guideline imposed upon it by Lloyd’s, and such breach shall remain unremedied for 30 days after the earlier of the date on which (A) a Responsible Officer of ACE becomes aware of such failure or (B) written notice thereof shall have been given to ACE by the Bank, then ACE will, upon written request of the Bank, use commercially reasonable efforts to procure the return of each Lloyd’s LOC from the beneficiary thereof (whether by obtaining a replacement letter of credit from another issuing bank or otherwise).

2.03 Reimbursement Obligations.

(a) Reimbursement. ACE agrees to reimburse the Bank in the amount of each LOC Disbursement made by the Bank in the currency in which such disbursement was made no later than the Reimbursement Due Date for such LOC Disbursement. 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 is not made by ACE on the date of the applicable LOC Disbursement, the Bank shall be deemed to have made an Advance to ACE, which shall be payable on the Reimbursement Due Date therefor and shall bear interest at a rate per annum equal to the Applicable Rate for each day from the date on which such LOC Disbursement was made to the date such Advance is paid in full; provided that interest on such Advance shall accrue at a rate per annum equal to the Applicable Rate plus 2.0% for each day on and after the Reimbursement Due Date such Advance is not paid in full.

(b) Obligation Unconditional. Except as provided in the proviso to the second sentence of Section 7.13, the obligation of ACE to reimburse the Bank for each LOC Disbursement 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:

(i) any lack of validity or enforceability of any Loan Document or any other agreement or instrument relating to any LOC (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 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 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) Right to make Payments under LOCs. ACE acknowledges that the Bank shall be entitled to make any payment in accordance with the terms of an LOC without any reference to or further authority from ACE or any other investigation or enquiry. ACE irrevocably authorizes the Bank to comply with any demand under an LOC which is valid on its face.

(d) Minimum Interest Rates.

(i) The rate of interest provided for in Section 2.03(a) of this Agreement is the minimum interest rate.

(ii) When entering into this Agreement, the parties hereto have assumed that the interest payable at the rates set out in Section 2.03(a) is not and will not become subject to Swiss Withholding Tax. Notwithstanding that the parties hereto do not anticipate that any payment of interest will be subject to Swiss Withholding Tax, they agree that, in the event that Swiss Withholding Tax should be imposed on interest payments by ACE, the payment of interest due by ACE shall be increased to an amount that (after making any deduction of the Non-refundable Portion of Swiss Withholding Tax as defined below) results in a payment to the Bank entitled to such payment of an amount equal to the payment which would have been due had no deduction of Swiss Withholding Tax been required. For this purpose, the Swiss Withholding Tax shall be calculated on the full grossed-up interest amount.

(iii) For the purposes of the foregoing, “Non-refundable Portion of Swiss Withholding Tax” means Swiss Withholding Tax at the standard rate (which, as of the date hereof, is 35%) unless according to an applicable double tax treaty, the Non-refundable Portion of Swiss Withholding Tax for the Bank is a specified lower rate, in which case such lower rate shall be applied in relation to the Bank. No payment pursuant to this clause (iii) shall be in duplication of any payment pursuant to Section 2.09.

(e) Refunds of Increased Interest. If the Bank becomes aware that it is entitled to claim a refund from a governmental authority in respect of increased interest paid pursuant to clause (d) above, the Bank shall promptly notify ACE of the availability of such refund claim and shall, within 30 days after receipt of a request by ACE, make a claim to such governmental authority for such refund at ACE’s expense, if obtaining such refund would not, in the good faith judgment of the Bank, be materially disadvantageous to the Bank; provided that nothing in this clause (e) shall be construed to require the Bank to institute any administrative proceeding (other than the filing of a claim for any such refund) or judicial proceeding to obtain any such refund. If the Bank determines, in its sole discretion, that it has received a refund in respect of any increased interest paid pursuant to clause (d) above, the Bank shall, within 60 days from the date of such receipt, pay over such refund to ACE (but only to the extent of the increased interest paid by ACE under clause (d) above giving rise to such refund), net of all out-of-pocket expenses of the Bank in obtaining such refund and without interest (other than interest paid by the relevant governmental authority with respect to the relevant portion of such refund); provided that ACE, upon request of the Bank, agrees to repay the amount paid over to ACE (plus penalties, interest or other charges) to the Bank in the event the Bank is required to repay such refund to such governmental authority. Nothing in this clause (e) shall be construed to require the Bank to make available its tax returns (or any other information relating to its taxes which it deems confidential) to ACE or any other Person.

2.04 Termination or Reduction of the Commitment. ACE may at any time, upon at least three Business Days’ notice to the Bank, terminate the Commitment in whole or reduce in part the unused portion of the Commitment Amount; provided that each partial reduction (i) shall be in an aggregate amount of $5,000,000 or a higher integral multiple of $1,000,000. Concurrently with any termination of the Commitment in whole pursuant to this Section 2.04, ACE shall (a) provide and thereafter maintain Collateral or backup letters of credit (pursuant to documentation satisfactory to the Bank and, in the case of backup letters of credit, from a financial institution acceptable to the Bank) with a Collateral Value equal to 101% of the Stated Amount of all LOCs that are outstanding from time to time and (b) pay to the Bank the principal amount of all outstanding Advances, all accrued and unpaid 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. The Commitment shall expire on the Final Expiration Date. For the avoidance of doubt, although the Commitment shall remain in effect after the Availability Termination Date, the Bank shall have no obligation to issue, extend the term of or increase the amount of any LOC after such date.

2.05 Commitment Fee; Upfront Fee. (a) ACE agrees to pay the Bank a commitment fee in Dollars, for the period from the Closing Date to the Availability Termination Date, at a rate per annum equal to the Commitment Fee Rate (determined in accordance with Schedule I) as in effect from time to time on the daily average of the unused portion of the Commitment Amount. The commitment fee shall be payable in arrears on the last Business Day of each calendar quarter and on the Availability Termination Date, in each case for the period then ending for which the commitment fee has not previously been paid.

(b) Any change in the Commitment Fee Rate shall take effect on the day on which the event giving rise to such change occurs.

(c) ACE agrees to pay the Bank in cleared funds an upfront fee in the amount and at the time separately agreed in writing between ACE and the Bank.

2.06 Letter of Credit Commission; Issuing Fees. (a) ACE agrees to pay to the Bank with respect to each LOC, for the period from the date of the issuance of such LOC to the date on which such LOC expires, is fully drawn or is otherwise terminated, a letter of credit commission in Dollars at a rate per annum equal to the LOC Commission Rate (determined from time to time in accordance with Schedule I) as in effect from time to time on the Stated Amount of such LOC. The letter of credit commission shall be payable in arrears on the last Business Day of each calendar quarter and on the Final Expiration Date (and, if applicable, thereafter on demand), in each case for the period then ending for which the letter of credit commission has not previously been paid.

(b) Any change in the LOC Commission Rate shall take effect on the day on which the event giving rise to such change occurs.

(c) ACE also agrees to pay the Bank such fees and charges with respect to each LOC as the Bank customarily requires in connection with the issuance, negotiation, processing and/or administration of letters of credit in similar situations.

2.07 Increased Costs, Etc.

(a) If, due to (i) the introduction of or any change in or in the interpretation of, in each case after the date hereof, any law or regulation, (ii) compliance with any guideline or request issued after the date hereof by any central bank or other governmental authority (whether or not having the force of law) or (iii) the introduction of or changeover to the Euro in any participating member state occurring after the date hereof, there shall be any increase in the cost to the Bank of agreeing to issue or of issuing or maintaining LOCs or the making of Advances (excluding, for purposes of this Section 2.07, any such increased costs resulting from (x) Taxes or Other Taxes (as to which Section 2.09 shall govern) and (y) changes in the basis of taxation of overall net income or overall gross income (or franchise taxes in lieu thereof) by the United States or by the foreign jurisdiction or state under the laws of which the Bank is organized or has its Lending Office or any political subdivision thereof), then ACE agrees to pay to the Bank, from time to time within five Business Days after demand by the Bank, which demand shall include a statement of the basis for such demand and a calculation in reasonable detail of the amount demanded, additional amounts sufficient to compensate the Bank for such increased cost. A certificate as to the amount of such increased cost, submitted to ACE by the Bank, shall be conclusive and binding for all purposes, absent demonstrable error.

(b) If, due to (i) the introduction of or any change in or in the interpretation of any law or regulation, in each case after the date hereof, (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) or (iii) the introduction of or changeover to the Euro in any participating member state occurring after the date hereof, there shall be any increase in the amount of capital required or expected to be maintained by the Bank or any corporation controlling the Bank as a result of or based upon the existence of the Commitment and other commitments of such type, then ACE agrees to pay to the Bank or such corporation, from time to

time within five Business Days after demand by the Bank or such corporation, which demand shall include a statement of the basis for such demand and a calculation in reasonable detail of the amount demanded, additional amounts sufficient to compensate the Bank or such corporation in the light of such circumstances, to the extent that the Bank or such corporation reasonably determines such increase in capital to be allocable to the existence of the Commitment. A certificate as to such amounts submitted to ACE by the Bank or such corporation shall be conclusive and binding for all purposes, absent demonstrable error.

(c) The Bank shall promptly notify ACE 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 the Bank’s good faith judgment, otherwise disadvantageous to the Bank) to mitigate or avoid, any obligation of ACE to pay any amount pursuant to Section 2.07(a), 2.07(b) or 2.09 (and, if the Bank has given notice of any such event and thereafter such event ceases to exist, the Bank shall promptly so notify ACE). Without limiting the foregoing, the 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 the Bank’s good faith judgment, be otherwise disadvantageous to the Bank.

(d) Notwithstanding the provisions of Section 2.07(a), 2.07(b) or 2.09 (and without limiting Section 2.07(c) above), if the Bank fails to notify ACE of any event or circumstance that will entitle the Bank to compensation pursuant to Section 2.07(a), 2.07(b) or 2.09 within 120 days after the Bank obtains actual knowledge of such event or circumstance, then the 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 the Bank notifies ACE of such event or circumstance.

2.08 Payments and Computations; Preservation of Rights; Settlement Conditional.

(a) Payments. ACE shall make each payment hereunder irrespective of any right of counterclaim or set-off not later than 1:00 P.M. on the day when due, in Dollars, to the Bank at such account as the Bank shall reasonably direct in immediately available funds, with payments being received by the Bank after such time being deemed to have been received on the next succeeding Business Day.

(b) Computations. All computations of interest on amounts denominated in Sterling shall be made by the Bank on the basis of a year of 365 or, if applicable, 366 days. All other computations of interest, and all computations of commitment fees and letter of credit commissions, shall be made by the Bank 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 computation is made.

(c) Business Days. 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.

(d) Preservation of Rights. Neither the obligations of ACE set out in this Section 2.08 nor the rights, powers and remedies conferred on the Bank by this Agreement or by law shall be discharged, impaired or otherwise affected by:

(i) the winding-up, dissolution, administration or reorganization of the Bank or any other Person or any change in its status, function, control or ownership;

(ii) any obligation of the Bank or any other Person hereunder or under any LOC or under any other security taken in respect of ACE’s obligations hereunder or otherwise in connection with any LOC being or becoming illegal, invalid, unenforceable or ineffective in any respect;

(iii) time or other indulgence being granted or agreed to be granted to the Bank or any other Person in respect of its obligations hereunder or under or in connection with any LOC or under any such other security;

(iv) any amendment to, or any variation, waiver or release of, any obligation of the Bank or any other Person under any LOC or this Agreement (unless agreed to by the Bank); or

(v) any other act, event or omission that, but for this Clause 2.08(d), might operate to discharge, impair or otherwise affect any of the obligations of ACE set out in this Section 2.08 or any of the rights, powers or remedies conferred upon the Bank by this Agreement or by law.

The obligations of ACE and the rights of the Bank in this Section 2.08 shall be in addition to and not in limitation of any other obligation of ACE or right of the Bank hereunder, under any other Loan Document or under applicable law.

(e) Settlement Conditional. Any settlement or discharge between ACE and the Bank shall be conditional upon no security or payment to the Bank by or on behalf of ACE being avoided or reduced by virtue of any law relating to bankruptcy, insolvency, liquidation or any similar law of general application, and if any such security or payment is so avoided or reduced, the Bank shall be entitled to recover the value or amount of such security or payment from ACE subsequently as if such settlement or discharge had not occurred.

2.09 Taxes.

(a) All payments by ACE hereunder shall be made, in accordance with Section 2.08, 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 taxes that are imposed on the Bank’s overall net income or overall gross income (or franchise taxes in lieu thereof) by the United States or by the foreign jurisdiction or state under the laws of which the Bank is organized or has its Lending Office or any political subdivision of any of the foregoing (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 the Bank, (i) the sum payable by ACE shall be increased as may be necessary so that after ACE has made all required deductions (including

deductions applicable to additional sums payable under this Section 2.09), the Bank 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 the Bank for and hold the Bank 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 2.09, imposed on or paid by the Bank 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 the Bank makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes, ACE shall furnish to the Bank the original or a certified copy of a receipt evidencing such payment (or, if such a receipt is not available, other evidence of such payment reasonably satisfactory to the Bank).

(e) The Bank shall, on or prior to the date of its execution and delivery of this Agreement, and from time to time thereafter as requested in writing by ACE (but only so long as the Bank remains lawfully able to do so), provide ACE with two original Internal Revenue Service forms W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that the Bank is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement.

(f) If, for any period with respect to which the Bank may lawfully do so, the Bank fails to provide ACE with the appropriate form described in Section 2.09(e) above (other than if such failure is due solely to a change in law occurring after the date hereof), the Bank shall not be entitled to indemnification under Sections 2.09(a) or 2.09(c) with respect to Taxes imposed by the United States by reason of such failure; provided that should the Bank become subject to Taxes because of its failure to deliver a form required hereunder, ACE shall take such steps as the Bank shall reasonably request to assist the Bank to recover such Taxes.

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

(h) Nothing in this Agreement shall (i) interfere with the right of the Bank to arrange its affairs (tax or otherwise) in whatever manner it thinks fit; (ii) oblige the Bank to investigate or claim any credit, relief, remission or repayment available to it to the extent, order and manner of any claim; or (iii) oblige the Bank to disclose any information relating to its affairs (tax or otherwise) or any computations in respect of tax.

2.10 LOC Applications and Administration.

(a) LOC Applications. The representations, warranties and covenants by ACE under, and the rights and remedies of the Bank under, the 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 Bank under, this Agreement and applicable law. In the event of any inconsistency between the terms of this Agreement and any LOC Application, this Agreement shall prevail.

(b) Administration. The Bank may rely upon any notice or other communication of any nature (written, electronic or oral, including telephone conversations and transmissions through the Bank’s remote access system, whether or not such notice or other communication is made in a manner permitted or required by this Agreement) purportedly made by or on behalf of the proper party or parties, and the Bank shall not have any duty to verify the identity or authority of any Person giving such notice or other communication.

2.11 Collateralization of LOCs.

(a) Voluntary Collateralization. ACE may at any time provide Collateral to secure any LOC (in which case the pricing applicable to such LOC shall be adjusted as set forth on Schedule I). If at any time the Collateral Value of all Collateral so provided is less than the aggregate Stated Amount of all Secured LOCs, then ACE shall designate from time to time the LOCs that are deemed to be Secured LOCs or provide additional Collateral in an amount sufficient to cause the Collateral Value to equal or exceed such aggregate Stated Amount.

(b) Collateralization upon Downgrade. If at any time the Financial Strength Rating of both Subsidiary Guarantors falls below A- by S&P and below A3 by ▇▇▇▇▇’▇, then ACE shall promptly, and in any event within five Business Days, provide and so long as such circumstance continues shall maintain Collateral with an aggregate Collateral Value not less than the Stated Amount of all outstanding LOCs (and all LOCs shall be deemed to be Secured LOCs).

(c) Collateralization due to Currency Fluctuations. If as of any Revaluation Date the Stated Amount of all LOCs exceeds the Commitment Amount, then ACE shall promptly, and in any event within five Business Days, provide and so long as such circumstance continues shall maintain Collateral with a Collateral Value equal to or greater than such excess.

(d) Releases of Collateral. If ACE has provided (or caused a Subsidiary Guarantor to provide) Collateral pursuant to the foregoing provisions of this Section 2.11 and no Default exists, then the Bank shall, promptly upon request by ACE, (i) release any Collateral granted pursuant to clause (a), (ii) release any Collateral granted pursuant to clause (b) so long as such request is accompanied by evidence, reasonably satisfactory to the Bank, that one of the Subsidiary Guarantors has a rating of A- or better from S&P or A3 or better from ▇▇▇▇▇’▇ and (iii) release any Collateral granted pursuant to clause (c) so long as such request is accompanied by evidence, reasonably satisfactory to the Bank, that after giving effect to such release, the Stated Amount of all LOCs will not exceed the Commitment Amount. In each of the foregoing cases, the Bank agrees to promptly deliver instructions and/or entitlement orders to the Custodian under the Control Agreement directing the Custodian to release such Collateral.

(e) Release of Security Interest. If the Commitment has terminated, no LOCs are outstanding and all liabilities owing to the Bank (other than contingent indemnity liabilities hereunder) have been paid or discharged in full, then the Bank shall, promptly upon request by (and at the expense of) ACE, take all actions reasonably requested by ACE to terminate the Security Agreement and the Control Agreement, any security interest arising thereunder and any Uniform Commercial Code filings made in connection therewith.

(f) Collateralization on Final Expiration Date. If any LOC remains outstanding after the Final Expiration Date, ACE shall promptly, and in any event within five Business Days, provide and so long as such circumstance continues shall maintain Collateral with a Collateral Value equal to Stated Amount of such LOC.

2.12 Bank Representation and Covenant. The Bank (a) represents that, as of the date of this Agreement, the Bank is an Approved Credit Institution and a Qualifying Bank; and (b) agrees that, if at any time it ceases to be an Approved Credit Institution, it will (i) promptly notify ACE and (ii) to the extent practicable, cause an Affiliate thereof that is an Approved Credit Institution and a Qualifying Bank to replace the Bank as the issuer of each LOC that has been issued for Funds at Lloyds.

There is no action, suit, investigation, litigation, arbitration 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 if adversely determined (i) would reasonably be expected 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.

4.07 Financials. The Consolidated balance sheet of ACE and its Subsidiaries as at December 31, 2009, 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 June 30, 2010, and the related Consolidated statements of income and cash flows of ACE and its Subsidiaries for the six months then ended duly certified by the Chief Financial Officer of ACE (such June 30, 2010 balance sheet and statements of income and cash flows, the “Interim Statements”), copies of which have been made available to the Bank, fairly present (subject, in the case of the Interim Statements, 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 Interim Statements, to the absence of footnotes). Since December 31, 2009, there has been no Material Adverse Change.

4.08 Accuracy of Information. No written information, exhibit or report furnished by or on behalf of ACE to the 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 (and in light of the circumstances under which) they were made.

4.09 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.

4.10 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.

4.11 Reimbursement Agreement Representations and Warranties. Each representation and warranty of ACE set forth in clauses (b), (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.

4.12 Governing Law and Enforcement. (a) With respect to each Loan Document that is governed by English law, the choice of English law as the governing law of such Loan Document will be recognized and enforced in ACE’s jurisdiction of incorporation.

(b) Any judgment obtained in England in relation to any Loan Document will be recognized and enforced in ACE’s jurisdiction of incorporation.

4.13 No Filing or Stamp Taxes. Under the laws of the jurisdiction of incorporation of ACE in force on the Closing Date, it is not necessary that the Loan Documents to which ACE is a party be filed, recorded or enrolled with any court or other authority in such jurisdiction or that any stamp, registration or similar tax be paid on or in relation to the Loan Documents to which it is party.

4.14 Liens. On the Closing Date, no Loan Party is subject to any agreement, judgment, injunction, order, decree or other instrument or any law or regulation that would prevent or otherwise interfere with such Loan Party’s obligation to deliver Collateral in the amounts, at the times and as otherwise provided in this Agreement and the Security Agreement.

ARTICLE V.

COVENANTS

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 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 Bank 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 mandatorily preferred by any bankruptcy, insolvency, liquidation or other similar laws of general application.

5.02 Use of LOCs. Ensure that (a) each Lloyd’s LOC is used solely for the purpose of Funds at Lloyd’s of a Member that is a Wholly-owned Subsidiary of ACE and is not a member of any syndicate at Lloyd’s other than the Syndicate, (b) no LOC that is included in the Funds at Lloyd’s of any Supported Member is the subject of any arrangement whereby (i) it is also included (through interavailability or otherwise) in the Funds at Lloyd’s of any other Member or (ii) it is or can be applied for any purpose other than meeting losses of that Supported Member; and (c) each other LOC is used for general corporate purposes.

5.03 Proportionate Use of LOC Facilities. Except to the extent that such ratios are affected by currency movements or drawdown after the date of issue of the relevant Lloyd’s LOCs and other letters of credit included in the Funds at Lloyd’s, in which case it shall use commercially reasonable efforts to restore such ratios to the equivalence required by this Section 5.03, ensure that:

(a) the ratio of (x) the Stated Amount of all Lloyd’s LOCs to (y) the Commitment Amount is at all times substantially the same as the ratio of (x) the Dollar Equivalent of the amount available for drawing under letters of credit included in the Funds at Lloyd’s of the Supported Members under each other LOC Facility to (y) the amount of the commitment under such other LOC Facility; and

(b) the ratio of (x) the Stated Amount of Lloyd’s LOCs included in the Funds at Lloyd’s of any Supported Member to the Stated Amount of Lloyd’s LOCs included in the Funds at Lloyd’s of each other Supported Member is at all times substantially the same as the ratio of (x) the Dollar Equivalent of the amount available for drawing under letters of credit included in the Funds at Lloyd’s of such Supported Member under each other LOC Facility to (y) the Dollar Equivalent of the amount available for drawing under letters of credit included in the Funds at Lloyd’s of each other Supported Member under such other LOC Facility.

5.04 Maintenance, Arrangement and Application of Funds at Lloyd’s.

(a) Ensure that there is included in the Funds at Lloyd’s of the Supported Members at all times an amount of Primary FAL such that the Bank, acting reasonably, is satisfied that the aggregate value that will be attributed to such Primary FAL by Lloyd’s for the purposes of determining the Supported Members’ syndicate premium limits in relation to the Syndicate for the following year of account, net of any liabilities taken into account in calculating the net

Funds at Lloyd’s of those Supported Members, will be not less than the Primary FAL Requirement.

(b) Ensure that at all times the amount of Primary FAL for each Supported Member is at least equal to the product of (x) the highest value of N_YOA given by the application of the formula below in respect of any open year of account and that Supported Member multiplied by (y) $100,000,000 (the sum of the Supported Members’ minimum Primary FAL, the “Primary FAL Requirement”):


N_YOA =		SMSPL_YOA
N_YOA =		AggSMSPL_YOA


		where:

		“SMSPL_YOA”		means the member’s syndicate premium limit of the Supported Member for the relevant year of account in respect of the Syndicate; and

		“AggSMSPL_YOA”		means the aggregate of the members’ syndicate premium limits of the Supported Members for the relevant year of account in respect of the Syndicate;

and “members’ syndicate premium limit” has the meaning given in Lloyd’s Definitions Byelaw (No. 7 of 2005).

(c) Ensure that no part of the Primary FAL of any Supported Member is the subject of any arrangement: (i) whereby it is also included (through interavailability or otherwise) in the Funds at Lloyd’s of any other Member; or (ii) whereby it is or can be applied for any purpose other than meeting losses of that Supported Member.

(d) Use commercially reasonable efforts (i) to ensure that the Primary FAL is applied to the fullest extent possible before any payment is made under (A) any LOC which is included in the Funds at Lloyd’s of any Supported Member or (B) any letter of credit issued under any other LOC Facility which is included in the Funds at Lloyd’s of any Supported Member; and (ii) from time to time on request by the Bank following any change made to the composition of the Funds at Lloyd’s of any Supported Member, to obtain a comfort letter from Lloyd’s, substantially in the form of Exhibit B, with respect to the order of application of Funds at Lloyd’s of each Supported Member.

5.05 Restrictions on Supported Members.

(a) Ensure that no Supported Member is at any time a member of any syndicate at Lloyd’s other than the Syndicate.

(b) Not at any time permit the aggregate underwriting capacity of the Supported Members to be greater than 115% of such capacity on the Closing Date without the prior written consent of the Bank (such consent not to be unreasonably withheld or delayed).

5.06 Control of Supported Members. Ensure that each Supported Member and the Managing Agent are at all times Wholly-owned Subsidiaries of ACE.

5.07 Syndicate Reporting. In addition to the financial reporting required by Section 5.08, (a) promptly, and in any event within 30 days after the request therefor, provide the Bank with such financial information regarding the Syndicate or any Supported Member as the Bank may from time to time reasonably request; and (b) use commercially reasonable efforts to provide the Bank notice of the occurrence of any event or condition that would reasonably be expected to materially increase the likelihood of a Lloyd’s LOC being drawn, provided that ACE’s failure to provide any notice pursuant to this clause (b) shall not constitute a Default or an Event of Default.

5.08 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.

5.09 “Know your customer” checks. If:

(a) the introduction of or any change in (or in the interpretation, administration or application of) any law or regulation made after the date of this Agreement;

(b) any change in the status of any Loan Party after the date of this Agreement; or

obliges the Bank (or, in the case of clause (c) above, any prospective transferee) to comply with “know your customer” or similar identification procedures in circumstances where the necessary information is not already available to it, promptly upon the request of the Bank supply, or procure the supply of, such documentation and other evidence as is reasonably requested by the Bank (for itself or, in the case of the event described in clause (c) above, on behalf of any prospective transferee) in order for the Bank or, in the case of the event described in clause (c) above, any prospective transferee to carry out and be satisfied it has complied with all necessary “know your customer” or other similar checks under all applicable laws and regulations pursuant to the transactions contemplated in the Loan Documents.

5.10 Post-Closing Conditions.

(a) Within 30 days after the Closing Date, provide the Bank with evidence that ACE (i) has terminated the unused “Commitments” under and as defined in the Existing FAL Facility Agreement, (ii) has paid all amounts then payable thereunder and (iii) has caused all letters of credit issued thereunder (except to the extent any such letters of credit will continue to be maintained by a financial institution (other than the Bank) acting in its individual capacity) to be replaced.

(b) Within 30 days after the Closing Date (or such longer time as the Bank may agree in writing), (i) execute and deliver the Security Agreement and the Control Agreement and (ii) provide an opinion letter with respect to the Security Agreement and the Control Agreement that is in form and substance, and from counsel, reasonably satisfactory to the Bank.

(c) Notwithstanding anything in this Agreement to the contrary, if ACE is required to collateralize any LOC prior to delivery of the Security Agreement and the Control Agreement as provided in Section 5.10(b), ACE shall within two Business Days deliver cash collateral directly to the Bank to be held by the Bank in an interest bearing account and otherwise on reasonable terms to be specified by the Bank after consultation with ACE, which ACE shall execute within two Business Days, until ACE has executed and delivered such Collateral Documents (and pledged the Collateral required thereunder) or the event giving rise to such requirement ceases to exist.

(d) Within 30 days after the Closing Date, cause to be executed and delivered (i) a certificate of the Secretary or Assistant Secretary of each of ACE Capital Limited, ACE Capital IV Limited and ACE Capital V Limited, certifying as to the names and true signatures of the officers or directors of such Person that are authorized to sign the FAL Providers’ Agreement on its behalf and (ii) certified copies of the resolutions of the Board of Directors of each of ACE Capital Limited, ACE Capital IV Limited and ACE Capital V Limited approving the execution and delivery of the FAL Providers’ Agreement.

(j) At any time it is or becomes unlawful for any Loan Party to perform or comply with any of its material obligations hereunder or under any other Loan Document or any court or arbitrator or any governmental body, agency or official which has jurisdiction in the matter shall decide, rule or order that any material provision of any of the Loan Documents is invalid or unenforceable;

(k) The registration of either Subsidiary Guarantor as an insurer shall be revoked, suspended or otherwise have restrictions or conditions placed upon it and such event would reasonably be expected to have a Material Adverse Effect on the interests of the Bank under the Loan Documents;

ARTICLE VII.

7.01 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 Bank (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.

7.02 Notices, Etc. All notices and other communications provided for hereunder shall be in writing (including facsimile or e-mail) and mailed or sent to the applicable party at its address set forth below its signature hereto.

partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

7.04 Costs and Expenses; Indemnification.

(a) ACE agrees to pay on demand all reasonable and documented costs and expenses of the Bank on a full indemnity basis together with any VAT thereon incurred in or in connection with (i) (A) the preparation, execution, delivery, administration, modification and amendment of the Loan Documents or (B) addressing any Default, in each case including the reasonable and documented fees and disbursements of a single counsel for the Bank and the lenders under the other LOC Facilities; and (ii) 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 disbursements of counsel for the Bank.

In the case of any investigation, litigation or other proceeding to which the indemnity in this Section 7.04(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 any LOC.

The Bank agrees 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.

7.06 Binding Effect. (a) This Agreement shall become effective when it shall have been executed by ACE and the Bank and thereafter shall be binding upon and inure to the benefit of ACE and the Bank and their respective successors and assigns, except that neither party shall have the right to assign its rights or obligations hereunder or any interest herein without the prior written consent of the other party (except (i) in the case of ACE, to the extent provided in the proviso to clause (x) of the first sentence of Section 2.01 and (ii) in the case of the Bank, (A) to the extent provided in the last sentence of Section 2.02(a) and (B) at any time after termination of the Commitment (by acceleration or otherwise), the Bank may assign its rights to payment hereunder (but not its obligations with respect to any outstanding LOC) to any Qualifying Bank, provided that such assignee has delivered a certificate to the Bank and ACE confirming that it is a Qualifying Bank.

(b) Notwithstanding clause (a) above, the Bank may at any time assign its rights and obligations hereunder with the prior written consent of ACE (such consent not to be unreasonably withheld or conditioned); provided that (i) ACE may condition such consent upon its receipt of a copy of a ruling from the Swiss Federal Tax Administration to the effect that the assignee will be treated as a single Non-Qualifying Bank for purposes of Swiss Withholding Tax matters, (ii) ACE may withhold its consent if the assignee is not an Approved Credit Institution and (iii) ACE may withhold its consent if such assignment would result in a breach of the Ten Non-Bank Rule or the Twenty Non-Bank Rule or otherwise result in any payment by ACE hereunder becoming subject to Swiss Withholding Tax. If the Bank makes any assignment in violation of this Section 7.06, then (A) the Bank shall reimburse and indemnify ACE for all losses, liabilities, taxes, costs and expenses incurred as a result thereof and (B) ACE shall not be required to make any increased payment to the Bank or the applicable assignee pursuant to Section 2.03(d) or Section 2.09. Clauses (i) and (iii) of the proviso to the first sentence of this Section 7.06(b) shall terminate and be of no further force or effect if the Commitments hereunder have terminated and all obligations of ACE hereunder have become forthwith due and payable (at maturity, by acceleration or otherwise).

(b) each payment of interest shall be made in the currency in which the sum in respect of which such interest is payable is denominated;

(d) each payment pursuant to Section 2.07 or 2.09 shall be made in the currency specified by the party claiming thereunder; and

(e) any amount expressed to be payable in a currency other than Dollars shall be paid in that other currency.

7.09 Economic and Monetary Union. If the United Kingdom becomes a participating member state with respect to the Euro, then:

(a) to the extent that any EMU legislation provides that an amount denominated either in Euro or in Sterling and payable within that participating member state by crediting an account of the creditor can be paid by the debtor either in the Euro unit or in Sterling, ACE shall be entitled to pay or repay any such amount payable hereunder either in the Euro unit or in Sterling;

(b) in addition to any method of conversion or rounding prescribed by any EMU legislation, each reference in this Agreement to a fixed amount in a national currency unit to be paid to or by the Bank shall be replaced by a reference to such comparable and convenient fixed amount in the Euro unit as the Bank may from time to time reasonably specify; and

(c) except as expressly provided in this Section 7.09, the Loan Documents shall be subject to such changes of construction or interpretation as the Bank may from time to time reasonably specify to be necessary to reflect the changeover to the Euro in the United Kingdom and to put the parties in the same position, so far as possible, that they would have been in if no change in currency had occurred.

7.10 Severability. Whenever possible each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision

of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement. All obligations of the Loan Parties and rights of the Bank expressed herein or in any other Loan Document shall be in addition to and not in limitation of those provided by applicable law.

7.12 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement (or any related agreement, including any amendment hereto or waiver hereunder) by facsimile or e-mail (in a .pdf or similar file) shall be effective as delivery of an original executed counterpart of this Agreement (or such related agreement).

7.13 No Liability of the Bank. ACE assumes all risks of the acts or omissions of any beneficiary or transferee of any LOC with respect to its use of such LOC. Neither the Bank nor any of its officers, directors, employees or agents shall be liable or responsible for: (a) the use that may be made of any LOC or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by the Bank against presentation of documents that do not strictly comply with the terms of an LOC, including failure of any documents to bear any reference or adequate reference to the LOC; or (d) any other circumstances whatsoever in making or failing to make payment under any LOC; provided that ACE shall have a claim against the Bank, and the Bank shall be liable to ACE, to the extent of any direct, but not consequential, damages suffered by ACE resulting from (i) the Bank’s willful misconduct or gross negligence as determined in a final, non-appealable judgment by a court of competent jurisdiction in determining whether documents presented under any LOC comply with the terms of such LOC or (ii) the Bank’s willful failure to make lawful payment under an LOC after the presentation to it of a draft and certificates strictly complying with the terms and conditions of such LOC. In furtherance and not in limitation of the foregoing, the Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

7.14 Confidentiality. The Bank shall not disclose any Confidential Information to any Person without the consent of ACE, other than (a) to the Bank’s Affiliates and its and their officers, directors, employees, agents and advisors, and to any direct, indirect, actual or prospective counterparty (and its advisor) to any swap, derivative or securitization transaction related to the obligations under this Agreement, in each case on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) as requested or required by any state, federal or foreign authority or examiner regulating the Bank or pursuant to any request of any self-regulatory body having or claiming authority to regulate or oversee any aspect of the Bank’s business or that of any of its Affiliates, (d) subject to a written agreement containing provisions substantially the same as those of this Section, to any other bank or other Person with

which the Bank enters or proposes to enter into a sub-participation arrangement as described in Section 7.07 and (e) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall agree to preserve the confidentiality of any Confidential Information received by it from the Bank and such disclosure otherwise complies with Regulation FD (with respect to any Confidential Information) under the Securities Exchange Act of 1934

7.15 Currency Indemnity. If, for the purposes of making or filing any claim of proof against any Loan Party, obtaining any order or judgment in any court or other tribunal or enforcing any order or judgment given or made in relation thereto or taking any action in exercise of its rights under the Loan Documents, it is necessary to convert a sum due hereunder in one currency into another currency, the rate of exchange used shall be that at which, in accordance with its normal banking procedures, the Bank could purchase the first currency with such other currency on the Business Day preceding that on which final judgment is given or such conversion is otherwise required to be made. The obligation of ACE in respect of any such sum due from it to the Bank hereunder shall, notwithstanding any judgment or other obligation in a currency (the “Obligation Currency”) other than that in which such sum is denominated in accordance with the applicable provisions of this Agreement (the “Agreement Currency”), be discharged only to the extent that on the Business Day following receipt by the Bank of any sum adjudged to be or that is otherwise due in the Obligation Currency, the Bank may in accordance with normal banking procedures purchase the Agreement Currency with the Obligation Currency. If the amount of the Agreement Currency so purchased is less than the sum originally due to the Bank in the Agreement Currency, ACE agrees, as a separate obligation and notwithstanding any such judgment or other determination, to indemnify the Bank against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Bank in such currency, the Bank agrees to return the amount of any excess to ACE (or to any other Person who may be entitled thereto under applicable law).

7.16 Jurisdiction, Etc. (a) Each party hereto irrevocably and unconditionally (i) submits, for itself and its property, to the nonexclusive jurisdiction of the courts of England, in any action or proceeding arising out of or relating to this Agreement or any other Loan Document, or for recognition or enforcement of any judgment with respect thereto; (ii) agrees that all claims in respect of any such action or proceeding may be heard and determined in the courts of England and (iii) agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document in the courts of any jurisdiction.

(b) Each party hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, (i) any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan Document in the courts of England; and (ii) the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(c) ACE irrevocably appoints ACE INA Services UK Limited with offices on the Closing Date at ACE Building, ▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇, as its agent

to receive, accept and acknowledge for and on its behalf service of any legal process, summons, notice and document that may be served in any action or proceeding described above. If for any reason such agent shall cease to be available to act as such, ACE agrees to promptly designate a new agent satisfactory to the Bank in London, England, to receive, accept and acknowledge for and on its behalf service of any legal process, summons, notice or document that may be served in any such action or proceeding. If ACE shall fail to designate such new agent, service of process in any such action or proceeding may be made on ACE by the mailing of copies thereof by express or overnight mail or courier, postage prepaid, to ACE at its address set forth below its signature hereto.

7.17 Governing Law. This Agreement and all non-contractual obligations arising in any way whatsoever out of or in connection with this Agreement shall be governed by, construed and take effect in accordance with, English law.

7.18 Waiver of Jury Trial. Each party hereto waives any right it may have to a jury trial of any claim or cause of action in connection with any Loan Document or any transaction contemplated by any Loan Document. This Agreement may be filed as a written consent to trial by court.

7.19 Certain Pledges. The Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement and the other Loan Documents to secure obligations of the Bank, including any pledge or assignment to secure obligations to a federal reserve or central bank; provided that no such pledge or assignment shall release the Bank from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

7.20 Certain Swiss Withholding Tax Matters. The Bank agrees that it will, and will cause any Person to which it sells any sub-participation to, promptly notify ACE if for any reason it ceases to be a Qualifying Bank. Without limiting the foregoing, if at any time ACE reasonably believes that the Bank’s status for Swiss Withholding Tax purposes has changed, then ACE may request that the Bank (and the Bank agrees that under such circumstances it will) promptly confirm whether it is a Qualifying Bank or a Non-Qualifying Bank.

Form of Deed of Subsidiary Guarantee

THIS DEED OF SUBSIDIARY GUARANTEE (this “Guarantee”) is executed as of November 18, 2010 by each of ACE BERMUDA INSURANCE LTD. and ACE TEMPEST REINSURANCE LTD. (collectively, the “Guarantors”), for the benefit of The ROYAL BANK OF SCOTLAND PLC (the “Bank”). Capitalized terms used but not defined herein have the respective meanings set forth in the Facility Agreement referred to below, and the rules of interpretation set forth in Section 1.02 of the Facility Agreement shall apply herein as if fully set forth herein, mutatis mutandis.

RECITALS

WHEREAS, pursuant to the Facility Agreement dated as of even date herewith (the “Facility Agreement”), between ACE Limited (“ACE”) and the Bank, the Bank has agreed to issue LOCs for the account of ACE and its Wholly-owned Subsidiaries; and

WHEREAS, each of the Guarantors will benefit from the issuance of LOCs pursuant to the Facility Agreement and is willing to guarantee the Guaranteed Obligations (as defined below) as hereinafter set forth;

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Guarantor agrees as follows:

1.01 The Guarantee.

(a) Each Guarantor hereby jointly and severally, unconditionally, absolutely and irrevocably guarantees the full and punctual payment (whether at stated maturity, upon acceleration or otherwise) of all amounts payable by ACE under or in connection with the Loan Documents (including any upfront fee payable pursuant to any fee letter between ACE and the Bank), including the principal of and interest (including, to the greatest extent permitted by law, post-petition interest) on reimbursement obligations and Advances owing by ACE pursuant to the Facility Agreement with respect to LOCs, and all fees, expenses, indemnities or any other obligations, whether now existing or hereafter incurred, created or arising and whether direct or indirect, absolute or contingent, or due or to become due (collectively, the “Guaranteed Obligations”). Upon failure by ACE to pay punctually any Guaranteed Obligation, each Guarantor agrees to pay forthwith on demand the amount not so paid at the place and in the manner specified in the Facility Agreement as if it was a principal obligor. Any amount payable hereunder shall be paid in the currency due under the Facility Agreement.

(b) Each Guarantor, and by its acceptance of this Guarantee, the Bank, hereby confirms that it is the intention of all such Persons that this Guarantee and the obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to this Guarantee and the obligations of each Guarantor hereunder. To effectuate the foregoing intention, the Bank and the

Exh. A-1

Guarantors hereby irrevocably agree that the obligations of each Guarantor under this Guarantee at any time shall be limited to the maximum amount as will result in the obligations of such Guarantor under this Guarantee not constituting a fraudulent transfer or conveyance.

(c) Each Guarantor jointly and severally, unconditionally and irrevocably agrees with the Bank that if any obligation guaranteed by it is or becomes void, voidable, unenforceable, invalid, illegal, or ineffective it will, as an independent and primary obligation, indemnify the Bank immediately on demand against any cost, loss or liability it incurs as a result of ACE not paying any amount which would, but for such unenforceability, invalidity or illegality, have been payable by it under the Loan Documents on the date when it would have been due. The amount payable by a Guarantor under this indemnity will not exceed the amount it would have had to pay under this Guarantee if the amount claimed had been recoverable on the basis of a guarantee.

1.02 Guarantee Unconditional. The obligations of each Guarantor under this Guarantee shall be unconditional, absolute and irrevocable and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by:

(a) any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of any other obligor under any of the Loan Documents, by operation of law or otherwise;

(b) any modification or amendment of or supplement to any of the Loan Documents;

(c) any release, non-perfection or invalidity of any direct or indirect security for any obligation of any other obligor under any of the Loan Documents;

(d) any change in the corporate existence, structure or ownership of any obligor, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting any other obligor or its assets or any resulting release or discharge of any obligation of any other obligor contained in any of the Loan Documents;

(e) the existence of any claim, set-off or other rights which any obligor may have at any time against any other obligor, the Bank or any other Person, whether in connection with any of the Loan Documents or any unrelated transactions, provided that nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim;

(f) any invalidity or unenforceability relating to or against any other obligor for any reason of any of the Loan Documents, or any provision of applicable law or regulation purporting to prohibit the payment by any other obligor of principal, interest or any other amount payable under any of the Loan Documents, including any law affecting compliance with Section 2.03(d) or Section 2.09(a) of the Facility Agreement;

(g) any law, regulation or order of any jurisdiction, or any other event, affecting any term of any obligation of the Bank’s rights with respect thereto; or

(h) any other act or omission to act or delay of any kind by any obligor, the Bank or any other Person or any other circumstance whatsoever which might, but for the provisions of

Exh. A-2

this clause (h), constitute a legal or equitable discharge of or defense to the obligations of either Guarantor under this Guarantee.

1.03 Discharge Only upon Payment in Full; Reinstatement in Certain Circumstances. Each Guarantor’s obligations under this Guarantee shall remain in full force and effect until the Commitment of the Bank under the Facility Agreement shall have terminated, no LOCs shall be outstanding and all amounts payable by the other Loan Parties under the Loan Documents shall have been paid in full. If at any time any payment of the principal of or interest on any reimbursement obligation, Advance or any other amount payable by any Loan Party under the Loan Documents is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of such Loan Party or otherwise, each other Loan Party’s obligations under this Guarantee, as applicable, with respect to such payment shall be reinstated as though such payment had been due but not made at such time.

1.04 Waiver by the Guarantors. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any right it may have of first requiring the Bank to make any demand of ACE or proceed against or enforce any other rights or security or claim payment from any Person or make or file any claim or proof in a winding-up or dissolution of ACE before claiming from that Guarantor under this Guarantee. This waiver applies irrespective of any law or any provision of the Loan Documents to the contrary.

1.05 Subrogation. Each Guarantor hereby unconditionally and irrevocably agrees not to exercise any rights that it may now have or hereafter acquire against any other Loan Party, or any other guarantor that arise from the existence, payment, performance or enforcement of such Loan Party’s obligations under or in respect of this Guarantee or any other Loan Document, including any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Bank against any other Loan Party or any other guarantor or any collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including the right to take or receive from any other Loan Party or any other guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all amounts payable under this Guarantee shall have been paid in full in cash, no LOCs shall be outstanding and the Commitment of the Bank under the Facility Agreement shall have expired or been terminated. If any amount shall be paid to either Guarantor in violation of the immediately preceding sentence at any time prior to the latest of (a) the payment in full in cash of all amounts payable under this Guarantee, and (b) the Final Expiration Date, such amount shall be received and held in trust for the benefit of the Bank, shall be segregated from other property and funds of such Guarantor and shall forthwith be paid or delivered to the Bank in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to all amounts payable under this Guarantee, whether matured or unmatured, in accordance with the terms of the Loan Documents, or to be held as collateral for any amounts payable under this Guarantee thereafter arising. If (i) any Guarantor shall make payment to the Bank of all or any amounts payable under this Guarantee, (ii) all amounts payable under this Guarantee shall have been paid in full in cash, and (iii) the Final Expiration Date shall have occurred, the Bank will, at such Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty,

Exh. A-3

necessary to evidence the transfer by subrogation to such Guarantor of an interest in the obligations resulting from such payment made by such Guarantor pursuant to this Guarantee.

1.06 Stay of Acceleration. If acceleration of the time for payment of any amount payable by any Loan Party under any of the Loan Documents is stayed upon the insolvency, bankruptcy or reorganization of such Loan Party, all such amounts otherwise subject to acceleration under the terms of the Facility Agreement shall nonetheless be payable by the other Loan Parties under this Guarantee forthwith on demand by the Bank.

1.07 Continuing Guarantee; Assignments. This Guarantee is a continuing guarantee and shall (a) remain in full force and effect until the latest of (i) the payment in full in cash of all amounts that are or may become payable under this Guarantee; and (ii) the Final Expiration Date, notwithstanding any settlement of account or other matter or thing whatsoever and shall not be considered satisfied by any intermediate payment or discharge in whole or in part, (b) be binding upon each Guarantor, its successors and assigns and (c) inure to the benefit of and be enforceable by the Bank and its successors and permitted assigns. Without limiting the generality of clause (c) of the immediately preceding sentence, upon the effectiveness of any assignment by the Bank made in accordance with the requirements of Section 7.06 of the Facility Agreement of all or any portion of the Bank’s rights and obligations under the Facility Agreement, such assignee shall become vested with all the benefits in respect thereof granted to the Bank herein or otherwise. Notwithstanding the foregoing, no Guarantor may, without the prior written consent of the Bank, assign any of its rights or obligations under this Guarantee.

1.08 Representations and Warranties. Each Guarantor represents and warrants to the Bank that:

(a) such Guarantor has received, or will receive, direct or indirect benefit from the making of this Guarantee and the Guaranteed Obligations;

(b) such Guarantor is familiar with, and has independently reviewed books and records regarding, the financial condition of the other Loan Parties; however, such Guarantor is not relying on such financial condition as an inducement to enter into this Guarantee;

(c) no Loan Party or any other Person has made any representation, warranty or statement to such Guarantor in order to induce such Guarantor to execute this Guarantee;

(d) as of the date hereof, each Guarantor is, individually and together with its Subsidiaries, Solvent (as defined in the Reimbursement Agreement); and

(e) the representations and warranties made by each Guarantor herein shall survive the execution hereof.

1.09 Miscellaneous.

(a) Notices, Etc. All notices and requests hereunder shall be given in accordance with Section 7.02 of the Facility Agreement and sent to the applicable party at its address set forth below it signature hereto, or at such other address as such party may, by written notice to the other parties, have designated as its address for such purpose.

Exh. A-4

(b) Governing Law. This Guarantee and all non-contractual obligations arising in any way whatsoever out of or in connection with this Guarantee shall be governed by, construed and take effect in accordance with, English law.

(c) Incorporation of Certain Provisions. Sections 7.01, 7.03, 7.10, 7.12, 7.15 and 7.16 of the Facility Agreement shall apply hereto as if fully set forth herein, mutatis mutandis (it being understood that references therein to “this Agreement” or “the Loan Documents” are references to this Guarantee).

Form of Comfort Letter

[Lloyd’s letterhead]

Dear Sir/Madam

I understand that ACE Limited, on behalf of itself and (the “Corporate Members”), has procured or may procure the provision to Lloyd’s of one or more letters of credit (“LOCs”) to form part of their Funds at Lloyd’s.

You have asked whether, in the event of monies having to be applied out of a Corporate Member’s Funds at Lloyd’s, the LOCs and other Funds at Lloyd’s of such Corporate Member may be drawn down in a pre-determined order whereby:

(a)	any drawdown on an LOC would not be made until such time as all other of such Corporate Member’s Funds at Lloyd’s had been applied; and

(b)

thereafter, if such Corporate Member has two or more LOCs included in its Funds at Lloyd’s, any drawdown under those LOCs will be effected on a pro rata basis (that is, the amount of the drawdown under each LOC will be the same percentage of the total outstanding amount available to be drawn down under such LOC).

As you are aware, the LOCs are held by Lloyd’s in its capacity as trustee under the terms of a Security and Trust Deed (substantially in the form STD (GEN) (10)) entered into by each Corporate Member. Any decision to draw down on any LOC involves an exercise of discretion in the light of the circumstances prevailing at the relevant time, and thus no binding undertaking can be given now.

However, I can confirm that at the time of considering the drawdown of a Corporate Member’s Funds at Lloyd’s, Lloyd’s would take into account the requested order of drawdown set out in the second paragraph of this letter.

For the avoidance of doubt, Lloyd’s shall not be responsible to you or any other person for any losses incurred by you or such other person as a consequence of acting in reliance upon this letter.

Yours faithfully,

Exh. B-1
