In accordance with the terms of the Purchase Contract Agreement, to be dated as of April 12, 2000, between the Company and The Bank of New York, as purchase contract agent (the "Purchase Contract Agent"), the Preferred Shares will be pledged by the Purchase Contract Agent, on behalf of the holders of the Securities, to The Bank of New York, as collateral agent (the "Collateral Agent"), pursuant to the Pledge Agreement, to be dated as of April 12, 2000 (the "Pledge Agreement"), among the Company, the Purchase Contract Agent and the Collateral Agent, to secure such holders' obligation to purchase Ordinary Shares under the Purchase Contracts.

Pursuant to a remarketing agreement (the "Remarketing Agreement") to be dated as of April 12, 2000, among the Company, the Purchase Contract Agent and a nationally recognized investment banking firm chosen by the Company, certain Preferred Shares may be remarketed, subject to certain terms and conditions. The Company and certain other entities affiliated therewith have filed with the Securities and Exchange Commission (the "Commission") a joint registration statement on Form S-3 (No. 333-78841) and pre-effective amendments nos. 1 and 2 thereto, for the registration of the Securities and certain other securities described therein under the Securities Act of 1933, as amended (the "1933 Act"), and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission under the 1933 Act (the "1933 Act Regulations"). Such registration statement has been declared effective by the Commission. Such registration statement, in the form in which it became effective, is referred to herein as the "Registration Statement"; and the final prospectus and the final prospectus supplement relating to the offering of the Securities, in the form first furnished to the Underwriters by the Company for use in connection with the offering of the Securities, are collectively referred to herein as the "Prospectus"; provided, however, that all references to the "Registration Statement" and the "Prospectus" shall also be deemed to include all documents incorporated therein by reference pursuant to the Securities Exchange Act of 1934, as amended (the "1934 Act"), prior to the time the applicable final prospectus and the final prospectus supplement were first furnished to the Underwriters by the Company; provided, further, that if the Company files a registration statement with the Commission pursuant to Rule 462(b) of the 1933 Act Regulations (the "Rule 462(b) Registration Statement"), then, after such filing, all references to "Registration Statement" shall also be deemed to include the Rule 462 Registration Statement. A "preliminary prospectus" shall be deemed to refer to any prospectus relating to the offering of the Securities that omitted information to be included upon pricing in a form of prospectus filed with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations and was used after the Registration Statement became effective and prior to the execution and delivery of this Underwriting Agreement. For purposes of this Underwriting Agreement, all references to the Registration Statement, Prospectus or preliminary prospectus or to any amendment or supplement to any of the foregoing shall be deemed to include any copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR"). All references in this Underwriting Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" (or other references of like import) in the Registration Statement, Prospectus or preliminary prospectus shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement, Prospectus or preliminary prospectus, as the case may be, prior to the execution of this Underwriting Agreement; and all references in this Underwriting Agreement to amendments or supplements to the Registration Statement, Prospectus or preliminary prospectus shall be deemed to mean and include the filing of any document under the 1934 Act which is incorporated by reference in the Registration Statement, Prospectus or preliminary prospectus, as the case may be, after the execution of this Underwriting Agreement. The Remarketing Agreement, the Purchase Contract Agreement, the Pledge Agreement and this Agreement are referred to collectively as the "Operative Agreements." The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Underwriters deem advisable after this Agreement has been executed and delivered. Section 1. Representations and Warranties. (a) Representations and Warranties by the Company. The Company represents and warrants to the Underwriters as of the date hereof, as of the Closing Time and, if applicable, as of each Date of Delivery (as defined below) (in each case, a "Representation Date"), as follows: (1) Compliance with Registration Requirements. The Company meets the requirements for use of Form S-3 under the 1933 Act. The Registration Statement (including any Rule 462(b) Registration Statement) has become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement (or such Rule 462(b) Registration Statement) has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information with respect to the Registration Statement (or any document incorporated therein by reference pursuant to the 1934 Act) has been complied with. 2 At the respective times the Registration Statement (including any Rule 462(b) Registration Statement) and any post-effective amendments thereto (including the filing of the Company's Annual Report on Form 10-K for the year ended December 31, 1999 with the Commission (the "Annual Report on Form 10-K")) became effective and at each Representation Date, the Registration Statement (including any Rule 462(b) Registration Statement) and any amendments thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. At the date of the Prospectus, at the Closing Time and at each Date of Delivery, if any, neither the Prospectus nor any amendments and supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement (or any amendment thereto) or the Prospectus made in reliance upon and in conformity with information furnished to the Company in writing by any Underwriter expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto). Each preliminary prospectus and prospectus filed as part of the Registration Statement as originally filed or as part of any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so filed in all material respects with the 1933 Act Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of the Securities will, at the time of such delivery, be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. (2) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission thereunder (the "1934 Act Regulations") and, when read together with the other information in the Prospectus, at the date of the Prospectus, at the Closing Time and at each Date of Delivery, if any, did not and will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. (3) Independent Accountants. The accountants who certified or shall certify the financial statements and any supporting schedules thereto of the Company included in the Registration Statement and the Prospectus are independent public accountants with respect to the Company and its subsidiaries as required by the 1933 Act and the 1933 Act Regulations. (4) Financial Statements. The financial statements of the Company included in the Registration Statement and the Prospectus, together with the related schedules and notes, as well as those financial statements, schedules and notes of any other entity included therein, present fairly the financial position of the Company and its consolidated subsidiaries, or such other entity, as the case may be, at the dates indicated and the statement of operations, stockholders' equity and cash flows of the Company and its consolidated subsidiaries, or such other entity, as the case may be, for the periods specified. Such financial statements have been prepared in conformity with United States generally accepted accounting principles ("GAAP") applied on a consistent basis throughout the periods involved, except as indicated therein or in the notes thereto. The supporting schedules, if any, included in the Registration Statement and the Prospectus present fairly in accordance with GAAP the information required to be stated therein. The selected financial data and the summary financial information, if any, included in the Prospectus present fairly the information shown therein and have been compiled on a basis consistent with that of the related audited financial statements included in the Registration Statement and the Prospectus.

(17) Non-Taxation of Current Payments. Except as disclosed in the Prospectus, under current laws and regulations of the Cayman Islands and Bermuda and any political subdivision thereof, all current payments in respect of Income PRIDES or Growth PRIDES may be paid by the Company to the holders thereof in United States dollars and freely transferred out of the Cayman Islands or Bermuda and all such payments made to holders thereof or therein who are non-residents of the Cayman Islands or Bermuda will not be subject to income, withholding or other taxes under laws and regulations of the Cayman Islands or Bermuda or any political subdivision or taxing authority thereof or therein and will otherwise be free and clear of any other tax, duty, withholding or deduction in the Cayman Islands or Bermuda or any political subdivision or taxing authority thereof or therein and without the necessity of obtaining any governmental authorization in the Cayman Islands or Bermuda or any political subdivision or taxing authority thereof or therein.

None of the Company or any subsidiary thereof is in violation of its charter or by-laws, partnership agreement or other constitutive documents or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any subsidiary thereof is a party or by which it or any of them may be bound, or to which any of the assets, properties or operations of the Company or any subsidiary thereof is subject (collectively, "Agreements and Instruments"), except for such defaults that would not reasonably be expected to result in a Material Adverse Change. The entry by the Company into the Purchase Contacts underlying the Income PRIDES, the offer of the Securities as contemplated herein and in the Prospectus, the issuance of the Ordinary Shares and the sale of the Ordinary Shares pursuant to the Purchase Contracts, the execution, delivery and performance by the Company of each of the Operative Agreements and any other agreement or instrument entered into or issued or to be entered into or issued by the Company in connection with the transactions contemplated hereby or thereby or in the Registration Statement and the Prospectus, and the consummation of the transactions contemplated herein and in the Registration Statement and the Prospectus (including, without limitation, the issuance and sale of the Securities, and the use of the proceeds from the sale of the Securities as described under the caption "Use of Proceeds") and compliance by the Company with its obligations hereunder and thereunder do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any assets, properties or operations of the Company or any subsidiary thereof pursuant to, any Agreements and Instruments (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that would not reasonably be expected to result in a Material Adverse Change), nor will such action result in any violation of the provisions of the charter or by-laws, partnership agreement or other constitutive documents of the Company or any subsidiary thereof or, to the best knowledge of the Company, any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any subsidiary thereof or over any of their assets, properties or operations, except for such violations under any applicable law, statute, rule, regulation, judgement, order, writ or decree as would not reasonably be expected to result in a Material Adverse Change. As used herein, a "Repayment Event" means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder's behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any subsidiary thereof. (20) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending or, to the knowledge of the Company, threatened, against or affecting the Company or any subsidiary thereof which is required to be disclosed in the Registration Statement and the Prospectus (other than as disclosed therein), or which would reasonably be expected to result in a Material Adverse Change, or which would reasonably be expected to materially and adversely affect the ability of the Company to perform its obligations any of the Operative Agreements to which it is a party. 7 (21) Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement, the Prospectus or the documents incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required. (22) Absence of Further Requirements. No consent, approval, authorization, or order of, or filing with, any governmental agency or body or any court, domestic or foreign, is required for the entry into the Purchase Contracts underlying the Income PRIDES or in connection with the issuance, offering and sale of the Securities and the issuance and sale of the Ordinary Shares by the Company pursuant to such Purchase Contracts, for the due authorization, execution or delivery by the Company of the Operative Agreements or for the performance by the Company of its obligations under any of the Operative Agreements, except such as have been obtained or made prior to the Closing Date, such as have been obtained and made under the 1933 Act, such filing of the Prospectus as has been made with the Bermuda Registrar of Companies under the Companies Act 1981 of Bermuda and such as may be required under state securities laws. (23) Possession of Licenses and Permits. The Company and its subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, "Governmental Licenses") issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by them, except where the failure to so possess any such Governmental Licenses would not, singly or in aggregate, reasonably be expected to result in a Material Adverse Change. The Company and its subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Change. Neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to result in a Material Adverse Change. (24) Insurance Laws. Each of the Company and its insurance subsidiaries (including insurance holding companies) is duly registered, licensed or admitted as an insurer or an insurance holding company (as applicable) in each jurisdiction where it is required to be so licensed or admitted to conduct its business as presently conducted, except where the failure to be so registered, licensed or admitted would not reasonably be expected to result in a Material Adverse Change; each of the Company and its insurance subsidiaries (including insurance holding companies) is in compliance with all applicable insurance statutes and regulations and has filed all reports, documents or other information required to be filed under such statutes and regulations, except where the failure to comply or file would not reasonably be expected to result in a Material Adverse Change. (25) Governmental Authorization. Except as set forth in the Registration Statement and the Prospectus, no authorization, approval or consent of any governmental authority or agency is required (other than any license as an insurer or insurance holding company and other than those which have already been obtained) under the laws of any jurisdiction in which the Company or any of its subsidiaries conduct their respective businesses in connection with the ownership, directly or indirectly, by the Company of equity interests in any subsidiary or the repatriation of any amount from or to the Company or any of its subsidiaries, except to the extent that the failure to obtain such authorization, approval or consent would not reasonably be expected to result in a Material Adverse Change. 8 (26) Commodity Exchange Act. The Securities, upon issuance, will be excluded or exempted under, or beyond the purview of, the Commodity Exchange Act, as amended (the "Commodity Exchange Act"), and the rules and regulations of the Commodity Futures Trading Commission under the Commodity Exchange Act (the "Commodity Exchange Act Regulations"). (27) Investment Company Act. The Company is not, and upon the issuance and sale of the Securities as herein contemplated and the application of the net proceeds therefrom as described in the Prospectus will not be, an "investment company" within the meaning of the Investment Company Act of 1940, as amended (the "1940 Act"). (b) Officers' Certificates. Any certificate signed by any officer of the Company or any of its subsidiaries and delivered to the Underwriters or to counsel for the Underwriters in connection with the offering of the Securities shall be deemed a representation and warranty by the Company or such subsidiary, as the case may be, to each Underwriter as to the matters covered thereby on the date of such certificate and, unless subsequently amended or supplemented, at each Representation Date subsequent thereto.

The option will expire automatically at the close of business on the 30th calendar day after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Underwriters to the Company setting forth the aggregate number of additional Option Securities as to which the several Underwriters are then exercising the option and the time, date and place of payment and delivery for such Option Securities. Any such time and date of payment and delivery (a "Date of Delivery") shall be determined by the Underwriters and the Company, but shall not be later than seven full business days after the exercise of said options, nor in any event prior to the Closing Time, unless otherwise agreed upon by the Underwriters and the Company. If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities each such Underwriter has severally agreed to purchase bears to the total number of Initial Securities, subject to such adjustments as the Underwriters in their discretion shall make to eliminate any sales or purchases of a fractional number of Option Securities. 9 (c) Pledge of Securities. The Preferred Shares will be pledged with the Collateral Agent to secure the obligations of holders of the Income PRIDES to purchase Ordinary Shares under the Purchase Contracts. Such pledge shall be effected by the transfer to the Collateral Agent of the Preferred Securities at the Closing Time and appropriate Date of Delivery, if any, in accordance with the Pledge Agreement. (d) Payment. Payment of the purchase price for, and delivery of, the Initial Securities shall be made at the offices of Brown & Wood LLP, One World Trade Center, New York, New York, or at such other place as shall be agreed upon by the Underwriters and the Trust, at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date of this Underwriting Agreement (unless postponed in accordance with the provisions of Section 10 hereof), or such other time not later than ten business days after such date as shall be agreed upon by the Underwriters and the Company (such time and date of payment and delivery being herein called "Closing Time"). In addition, in the event that the Underwriters have exercised their option to purchase any or all of the Option Securities, payment of the purchase price for, and delivery of such Option Securities, shall be made at the above-mentioned offices of Brown & Wood LLP, or at such other place as shall be agreed upon by the Underwriters and the Company, on the relevant Date of Delivery as specified in the notice from the Underwriters to the Company. Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Underwriters for the respective accounts of the Underwriters of the Securities to be purchased by them. It is understood that each Underwriter has authorized Merrill Lynch, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Securities which it has severally agreed to purchase. Merrill Lynch, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder. (e) Denominations; Registration. The Securities and certificates for the Securities shall be in such denominations and registered in such names as the Underwriters may request in writing at least one full business day prior to the Closing Time or the relevant Date of Delivery, as the case may be. The Securities and certificates for the Securities will be made available for examination and packaging by the Underwriters in The City of New York not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be. Section 3. Covenants of the Company. The Company covenants with each Underwriter as follows: (a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will notify the Underwriters immediately, and confirm the notice in writing, of (i) the effectiveness of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Prospectus, (ii) the receipt of any comments from the Commission, (iii) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as they deem necessary to ascertain promptly whether the Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, they will promptly file the Prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment. 10 (b) Filing of Amendments. The Company will give the Underwriters notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) of the 1933 Act Regulations) or any amendment, supplement or revision to either the prospectus included in the Registration Statement at the time it became effective or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Underwriters with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will give the Underwriters a reasonable opportunity to comment on any such document prior to such proposed filing or use, as the case may be. (c) Delivery of Registration Statements. The Company has furnished or will deliver to the Underwriters and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Underwriters, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters. The Registration Statement and each amendment thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. (d) Delivery of Prospectuses. The Company will deliver to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter may reasonably request, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Prospectus as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. (e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Underwriting Agreement and in the Registration Statement and the Prospectus. If at any time when the Prospectus is required by the 1933 Act or the 1934 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or to amend or supplement the Prospectus in order that the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as the Underwriters may reasonably request. 11 (f) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Underwriters may designate and to maintain such qualifications in effect for a period of not less than one year from the date of this Underwriting Agreement; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which they are not so qualified or to subject themselves to taxation in respect of doing business in any jurisdiction in which they are not otherwise so subject. In each jurisdiction in which the Securities have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the date of this Underwriting Agreement. (g) Earnings Statement. The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

The foregoing sentence shall not affect the ability of the Company to take any such action (i) in connection with any employee benefit, dividend reinvestment and stock option or stock purchase plans of the Company or its subsidiaries; (ii) in connection with the offering of the Securities issued pursuant to this Agreement; (iii) in connection with any securities issued pursuant to or sold in connection with any securities of the Company or its subsidiaries, outstanding as of the date hereof, that are convertible into or exercisable or exchangeable for or repayable with any securities of the Company and its subsidiaries; (iv) in connection with Growth PRIDES or Income PRIDES to be created or recreated upon substitution of Pledged Securities, or Ordinary Shares issuable upon early settlement of the Income PRIDES or Growth PRIDES; (v) in connection with any merger, acquisition or acquisition of assets by the Company, the consideration for which are securities of the Company; or (vi) upon exercise of stock options. 12 (j) Reporting Requirements.

All payments to be made by the Company hereunder shall be made without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company shall pay such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made. (l) Reserve of Ordinary Shares. The Company will reserve and keep available at all times, free of preemptive or other similar rights and liens and adverse claims, sufficient Ordinary Shares to satisfy any obligations to issue Ordinary Shares upon settlement of the Purchase Contracts and shall take all actions necessary to keep effective the Registration Statement with respect to the Ordinary Shares.

Indemnification. (a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows: (1) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (2) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and (3) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (1) or (2) above; provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Underwriters expressly for use in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto). (b) Indemnification of the Company, Directors and Officers. Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Underwriters expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment or supplement thereto). 17 (c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(2) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. Section 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Underwriting Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. 18 The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Underwriting Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Securities (before deducting expenses) received by the Company and the total underwriting commission received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of such Securities as set forth on such cover. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Initial Securities set forth opposite their respective names in Schedule A hereto, and not joint. Section 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Underwriting Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of and payment for the Securities. 19 Section 9. Termination. (a) Underwriting Agreement. The Underwriters may terminate this Underwriting Agreement by notice to the Company, at any time at or prior to the Closing Time, if (i) there has been, since the time of execution of this Underwriting Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change, or any development or event involving a prospective material adverse change, in the financial condition, business or results of operations of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) there has occurred any material adverse change in the financial markets in the United States or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case referred to in this clause (ii), the effect of which is such as to make it, in the judgment of the Underwriters, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange or the American Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or (iv) a banking moratorium has been declared by either U.S. Federal, New York or Bermuda authorities. (b) Liabilities. If this Underwriting Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. Section 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time or the relevant Date of Delivery, as the case may be, to purchase the Securities which it or they are obligated to purchase under this Underwriting Agreement (the "Defaulted Securities"), then the Underwriters shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Underwriters shall not have completed such arrangements within such 24-hour period, then: (a) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date pursuant to this Underwriting Agreement, the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations under this Underwriting Agreement bear to the underwriting obligations of all non-defaulting Underwriters, or (b) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date pursuant to this Underwriting Agreement, this Underwriting Agreement (or, with respect to the Underwriters' exercise of the over-allotment option for the purchase of Option Securities on a Date of Delivery after the Closing Time, the obligations of the Underwriters to purchase such Option Securities on such Date of Delivery) shall terminate without liability on the part of any non-defaulting Underwriter. No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default. 20 In the event of any such default which does not result in (i) a termination of this Underwriting Agreement or (ii) in the case of a Date of Delivery after the Closing Time, a termination of the obligations of the Underwriters and the Company with respect to the related Option Securities, as the case may be, either the Underwriters or the Company shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements. Section 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

Sch-B-1 Exhibit A FORM OF OPINION OF MAPLES AND CALDER, THE COMPANY'S CAYMAN ISLANDS COUNSEL, TO BE DELIVERED PURSUANT TO SECTION 5(b) (1) The Company has been duly incorporated and is validly existing and in good standing as an exempted company, under the laws of the Cayman Islands, and has the corporate power and corporate authority to own, lease and operate its property, and to conduct its business, as described in the Registration Statement and the Prospectus, and to enter into and perform its obligations under, or as contemplated under, the Operative Agreements. (2) The authorized share capital of the Company, as set out in its Memorandum and Articles of Association, conforms as to legal matters to the description thereof contained in the Registration Statement and the Prospectus. (3) The Operative Agreements have been duly authorized, executed and delivered by the Company. (4) The execution and delivery by the Company of, and the performance by the Company of its obligations under, the Operative Agreements do not and will not (A) violate any provision of the Memorandum and Articles of Association of the Company; (B) contravene any provision of any law, public rule or regulation of the Cayman Islands applicable to the Company; (C) to the best of such counsel's knowledge, contravene any existing published order or decree of the courts of the Cayman Islands by which the Company is bound or by which its properties or assets may be affected; or (D) require any consent, approval or authorization or order of, or qualification with, any Cayman Islands governmental agency in connection with the offer and sale of the Securities. (5) To the best of such counsel's knowledge, but based only upon a search of the cause list at the offices of the Grand Courts of the Cayman Islands, there was no action, suit or proceeding to which the Company is a party or to which the assets, properties or operations of the Company is subject, before the courts of the Cayman Islands at the close of business on [specify a recent date]. (6) All statements made in the Prospectus with regard to statutes, regulations, rules, treaties and other laws of the Cayman Islands (including, but not limited to, insurance, regulatory and tax matters and the Companies Law (1998 Revision) of the Cayman Islands) and enforcement of judgments in the Cayman Islands are accurate. (7) Pursuant to the Underwriting Agreement, and to the extent that the laws of the Cayman Islands are relevant, the Company has legally, validly, effectively and irrevocably submitted to the jurisdiction of the United States Federal and New York State courts sitting in the Borough of Manhattan in The City of New York, State of New York, and has legally, validly and effectively appointed ACE USA, Inc. as the authorized agent of the Company for the purposes described in Section 13 of the Underwriting Agreement assuming this to be the case as a matter of the applicable United States Federal and New York State laws. A-1 (8) The choice of the laws of the State of New York, United States of America as the governing law of the Underwriting Agreement is a valid and effective choice of law and in an action brought before a court of competent jurisdiction in the Cayman Islands, the laws of the State of New York would, to the extent specifically pleaded and proved as a fact by expert evidence, be recognized and applied by such court to all issues concerning the formal and essential validity of the Underwriting Agreement and the interpretation thereof, except that in any such action such court will apply those laws of the Cayman Islands as such court characterizes as procedural, and will not apply those laws of the State of New York as such court characterizes as procedural. (9) Although there is no statutory enforcement in the Cayman Islands of a judgment obtained in New York, the courts of the Cayman Islands will recognize and enforce a foreign judgment of a court of competent jurisdiction, based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided such judgment is final, for a liquidated sum, not in respect of taxes or a fine or penalty, and was not obtained in a manner and is not of a kind the enforcement of which is contrary to the public policy of the Cayman Islands. A Cayman Islands court may stay proceedings if concurrent proceedings are being brought elsewhere. For the purposes of enforcement of a judgment granted against the Company in respect of the Underwriting Agreement, a court in the Cayman Islands would recognize the jurisdiction of the applicable federal or state court to the jurisdiction of which the Company has submitted rendering such judgment if service of process on the Company is effected pursuant to and in accordance with the provisions of the Underwriting Agreement. (10) On the basis that the Company carries on its business as set forth in the Prospectus, there is no requirement that it be licensed under the Insurance Law, 1979, as amended of the Cayman Islands. (11) The Securities to be purchased by the Underwriters from the Company have been authorized for issuance and sale to the Underwriters and, when issued and delivered by the Company pursuant to the Underwriting Agreement against payment of the consideration set forth therein, will be validly issued and fully paid and non-assessable; the issuance of such Securities will not be subject the preemptive or other similar rights arising by law or otherwise. (12) The Ordinary Shares subject to the Purchase Contract Agreement have been validly authorized and reserved for issuance and, when issued and delivered by the Company in accordance with the provisions of the Purchase Contract Agreement, the Purchase Contracts and the Pledge Agreement, will be fully paid and non-assessable; the issuance of such Ordinary Shares will not be subject to preemptive or other similar rights arising by law or otherwise. A-2 (13) The Preferred Shares have been duly authorized for issuance by the company and, when issued and delivered against payment therefor as provided in the Prospectus, will be validly issued and fully paid and non-assessable. The issuance of the Preferred Shares will not be subject to preemptive or other similar rights. All corporate action required to be taken for the authorization, issuance and delivery of the Preferred Shares has been validly taken. [In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws other than the laws of the Cayman Islands, to the extent such counsel deems proper and specified in such opinion, upon the opinion of other counsel whom such counsel believes to be reliable (which opinion shall be dated and furnished to the Underwriters at the Closing Time, shall be satisfactory in form and substance to counsel for the Underwriters and shall expressly state that the Underwriters may rely on such opinion as if it were addressed to them), provided that such counsel shall state in their opinion that they believe that they and the Underwriters are justified in relying upon such opinion, and (B) as to matters of fact (but not as to legal conclusions), to the extent such counsel deems proper, on certificates of responsible officers of the Company, its subsidiaries and public officials.] A-3 Exhibit B FORM OF OPINION OF CONYERS DILL & PEARMAN, THE COMPANY'S BERMUDA COUNSEL, TO BE DELIVERED PURSUANT TO SECTION 5(b) (1) Each of ACE Bermuda Insurance Ltd. and Tempest Reinsurance Company Limited (collectively, the "Bermuda Insurance Subsidiaries") (A) is validly existing under the laws of Bermuda as a company with limited liability and is in good standing under the laws of Bermuda (meaning that such company has not failed to make any filing with any Bermuda government authority or to pay any Bermuda government fee or tax, the failure of which would make such company immediately liable to be struck off the Register of Companies and thereby cease to exist under the laws of Bermuda) and (B) the corporate objects and powers contained in the Memorandum of Association of each of the Bermuda Insurance Subsidiaries are sufficient to allow them to carry on their business and to own, lease and operate its properties as both are described in the Prospectus. (2) The Company is validly registered under the Companies Act 1981 as a Permit Company and is in good standing under the laws of Bermuda (meaning that such company has not failed to make any filing with any Bermuda government authority or to pay any Bermuda government fee or tax which is required to be paid in respect of Permit Companies in Bermuda). (3) Based solely upon a certified copy of the Register of Members for each of the Bermuda Insurance Subsidiaries, and without further inquiry, (A) all of the issued shares in the share capital of each of the Bermuda Insurance Subsidiaries have been duly and validly authorized and issued and are fully paid and nonassessable (meaning that no further sums are required to be paid by the holders thereof in connection with the issue of such shares); and (B) the Company is the registered holder of all the issued shares of each of the Bermuda Insurance Subsidiaries. (4) Each of the Bermuda Insurance Subsidiaries is duly registered as an insurer under the Insurance Act of 1978 (Bermuda) and the regulations promulgated thereunder (together, the "Insurance Act") and as so registered, each Bermuda Insurance Subsidiary may conduct the insurance business as described in the Prospectus; and based solely on the Certificates of Compliance and without independent inquiry, each of the Bermuda Insurance Subsidiaries has filed with the appropriate Bermuda governmental authority all reports, documents or other information required to be filed under the Insurance Act. (5) The Company is not registered as an insurer under the Insurance Act and is therefore not required to comply with the requirements of the Insurance Act applicable to registered insurers. (6) The execution and delivery by the Company of, and the performance by the Company of its obligations under the Operative Agreements do not and will not (A) violate any provision of the Memorandum of Association or By-laws of either of the Bermuda Insurance Subsidiaries or any applicable law, regulation, order or decree in Bermuda; (B) based solely upon the Cause Book, contravene any judgment, order or decree by the Bermuda Supreme Court against the Company or the Bermuda Insurance Subsidiaries; or (C) require any consent, approval or authorization or order of, or qualification with, any Bermuda governmental agency. (7) Based solely upon the Cause Book and without further inquiry, there is no action, suit or proceeding now pending before the Bermuda Supreme Court against the Company or the Bermuda Insurance Subsidiaries or any of their respective properties. B-1 (8) All statements made in the Registration Statement and Prospectus with respect to statutes, regulations, rules, treaties and other laws of Bermuda (including, but not limited to, statements made with respect to the Insurance Act and Bermuda tax matters) fairly and accurately present the information set forth therein and such counsel's opinion as to such matters. [In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws other than the laws of Bermuda, to the extent such counsel deems proper and specified in such opinion, upon the opinion of other counsel whom such counsel believes to be reliable (which opinion shall be dated and furnished to the Underwriters at the Closing Time, shall be satisfactory in form and substance to counsel for the Underwriters and shall expressly state that the Underwriters may rely on such opinion as if it were addressed to them), provided that such counsel shall state in their opinion that they believe that they and the Underwriters are justified in relying upon such opinion, and (B) as to matters of fact (but not as to legal conclusions), to the extent such counsel deems proper, on certificates of responsible officers of the Company, its subsidiaries and public officials.] B-2 Exhibit C FORM OF OPINION OF PETER N. MEAR, ESQ., GENERAL COUNSEL OF THE COMPANY, TO BE DELIVERED PURSUANT TO SECTION 5(b) (1) The Company is qualified to do business, and is in good standing, as a foreign corporation, under the laws of each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or to be in good standing would not singly or in the aggregate result in a Material Adverse Change; (2) Each of ACE Bermuda Insurance Ltd., Tempest Reinsurance Company Limited, ACE USA, Inc. and ACE INA Holdings Inc. is qualified to transact business and is in good standing (with respect to jurisdictions which recognize such concept) in each jurisdiction in which it owns or leases real property or in which the conduct of its business requires such qualification, except where the failure to be so qualified or to be in good standing (with respect to jurisdictions which recognize such concept) would not singly or in the aggregate result in a Material Adverse Change; (3) Except as set forth in the Registration Statement and the Prospectus, such counsel does not know of any outstanding (A) securities or obligations of the Company convertible into or exchangeable for any shares of capital stock of the Company or any of its subsidiaries; (B) rights, warrants or options to acquire or purchase from the Company any shares of capital stock of the Company or any such convertible or exchangeable securities or obligations; or (C) obligations or understandings of the Company to issue or sell any shares of capital stock of the Company or any of its subsidiaries, any such convertible or exchangeable securities or obligations, or any such warrants, rights or obligations; and (4) To the best of such counsel's knowledge, and other than as disclosed in the Prospectus, there are no threatened legal proceedings against the Company or any of its subsidiaries which, if determined adversely to the Company or such subsidiary, would result in a Material Adverse Change. [In rendering such opinion, such counsel may rely as to matters of fact (but not as to legal conclusions), to the extent such counsel deems proper, on certificates of responsible officers of the Company, its subsidiaries and public officials.] C-1 Exhibit D FORM OF OPINION OF MAYER, BROWN & PLATT, UNITED STATES COUNSEL FOR THE COMPANY, TO BE DELIVERED PURSUANT TO SECTION 5(b) (1) Each of ACE INA Holdings Inc. and ACE USA, Inc. is duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Delaware.

(3) The Operative Agreements have been duly authorized, executed and delivered by the Company. (4) Assuming due authorization, execution and delivery of the Purchase Contract Agreement by the Purchase Contract Agent, the Purchase Contract Agreement constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally or by general equitable principles (regardless of whether enforcement is considered in a proceeding at law or in equity). D-1 (5) Assuming due authorization, execution and delivery of the Pledge Agreement by the Collateral Agent and the Purchase Contract Agent, the Pledge Agreement constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfers), reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally or by general equitable principles (regardless of whether enforcement is considered in a proceeding at law or in equity).
